The person who was called a silly bag in the limerick was the director of another 100-ton construction factory. However, he was implicated by Sun Shanming and Lin Zhenkang. As soon as the joke came out, he was also looked at by the public. Some people took the opportunity to vent their dissatisfaction with him and were eventually slandered as a silly bag.

Li Qinjun, a native of Liaoning, went abroad to study abroad during the Beiyang period and graduated from a major in science and engineering. After returning to China, he entered a shipyard in the Northeast and became a teacher at the shipyard. He systematically studied ship-related design and construction, and participated in or presided over a large number of ship construction.

Before September 18, he had already started the army and was responsible for all the work of a small boat dock for several years. After September 18, the shipyard was taken away by Japanese merchants, and he also quietly retreated south with his family and his family.

Finally, he came to Shanghai and rejoined a shipyard, but his resume was not outstanding. Most of the ships he participated in were small boats that could only sail in the sea, while most of the ships he was responsible for were motorized ships running in the inland rivers, mainly iron-hulled ships, iron-hulled ships, and even a lot of work was used to modify the sails.

So he didn't have a high position in the shipyard in Shanghai and did some auxiliary work, so when the Lin family came to him, he agreed readily.

His resume is not the best among the people recruited by the Lin family, but the small dock he was responsible for was very similar to the 100-ton construction factory in the Lin family, and the ships he made were very similar. In addition, the construction factory was only the lowest level in the Lin family's shipyard, so he was appointed as the factory director after considering it.

Its performance can also be said to be fully in line with the Lin family's imagination of the shipyard manager. They understand technology and various technical problems. Even if they cannot solve them themselves, they can organize technical personnel to handle them properly. When encountering problems that cannot be solved in the factory, they are also very clear about what help they need and can report them accurately, clearly and meticulously. As long as the Lin family does as they follow, they will basically not encounter any wrong words.

All matters in the shipyard are handled in an orderly manner, and all matters are progressed in an orderly manner. They have a very thorough understanding of the needs of the Lin family, and can propose various effective solutions, solutions, etc. to solve the needs of the Lin family.

The source of the dirty water was ridiculed as a new ship designed and built by its organization. It suffered a serious failure during the test and finally sank. Judging from the results alone, it was the most serious accident among the three shipyards so far.

But the accident has nothing to do with it. When the Lin family purchased the power system components of the ship, the seller mixed some defective products into it, which were not even considered defective products, but scrap products that should not be produced by the factory.

When testing the ship, the engine transmission shaft suddenly broke down because it was running at full power at that time. The broken transmission shaft broke the rod and debris were extremely powerful, which damaged the engine and broke through the oil pipeline, causing the ship to lose its main power and the cabin to catch fire.

Because it is a small boat, the main engine and the auxiliary power engine are in the same cabin. When the fire is on, the temperature will rise rapidly. The two engines as auxiliary power will stop one after another due to the temperature.

Fortunately, the captain of the test ship was experienced, and Li Qinjun had given me a detailed advice in advance. As soon as the ship had a problem, he immediately sailed to the shore. When the ship was completely powered, he was not far from the shore. The captain immediately decided to abandon the boat and swam ashore, otherwise there would be casualties.

The test section of the river was very fast. Even if it was not far from the shore, the crew members were in danger when they came ashore. The boat was taken away by the water flow. After hitting the reef several times, they sank directly. They were salvaged behind them. They found that the river water was also swept away, and it was unimaginable that people were swept away.

The Lin family organized many people to study the reasons for the ship's problems. The final conclusion was that there were serious problems with the transmission shaft, and during the blast material processing stage, serious hidden injuries were caused on the steel due to improper operation, which caused the processed transmission shaft to have great defects.

This defect problem is very obvious. It can be easily discovered in all aspects such as processing and inspection. The things should be scrapped directly, but for some reason, they continue to process, and finally let the dealer mix them in the good ones and sell them to the Lin family.

Through inspections of other goods purchased from the same dealer, some problematic products were found, and the other party obviously did it on purpose, so the problem occurred to the dealer and the Lin family, who did not know much about the industry.

As for the shipyard, one thing was purchased by the Lin family; the other was that others had covered up the problem, which was very difficult to find, and the shipyard did not have a corresponding inspection department.

During this period, few domestic factories could have a complete process, which is normal, but the shipyard has learned its lesson and organized special personnel to carefully inspect the purchased materials, parts, etc. before using them.

When building a new ship, Li Qinjun was not as fond of merit as Sun Shanming, nor was he like Lin Zhenkang. He was so itchy when he saw others' glory. Instead, he actually believed that the Lin family needed such a ship to organize people, conduct research, design and build them.

Li Qinjun was in charge of designing and building a small boat of twenty or thirty tons, which was used to drag or push other ships, that is, a small tugboat.

The reason is that when we learned that the Lin family modified the ships mainly for normal navigation on the Yangtze River waterways entering and leaving Sichuan and Chongqing, it was believed that even if the Three Gorges River section had very rapid water flow, only a small part of the river section, there was no need to install a larger horsepower power system for the ship to pass through this small part of the river section normally.

The purpose of developing tugboats in this section of the river is to help the ship navigate through towing, pushing, etc., so that the carrier ships can choose to assemble a power system with a lower power, so that they can navigate inside and outside Sichuan and Chongqing, thereby reducing the cost of modification.

After all, the waterway with extreme conditions only accounts for a very small part of the entire journey, and for this small part, it is definitely not cost-effective to significantly increase the installed power.

Normal commercial shipping emphasizes cost-effectiveness, that is, the unit price or cost of cargo transportation should be as low as possible. Even if a high-power engine is installed, it is necessary to make a choice between speed and consumption during normal navigation.

During water transportation, the speed and fuel consumption increase in proportion. Even if the installed power is very sufficient, it is likely that it will not be used in normal navigation in order to consider economics. So the excess power will not be used most of the time, isn’t it a waste?

The Lin family lacks transportation capacity, but transporting raw materials, equipment, etc. can take thousands of kilometers, and the products produced may have to be transported out of Sichuan. Therefore, the Lin family still needs economic considerations for most transportation, and this ship type is also very suitable for the needs of the Lin family.

Moreover, the transportation capacity and reducing loading power are not completely in conflict with each other. Even if the Lin family is not short of money to purchase many high-horsepower engines, the difficulty of getting high-horsepower and lower-horsepower engines is different.

Even the difficulty and time of installing the two onto the ship are different. The difficulty and time of installing the transport ship with a lower horsepower engine can obviously provide more modified ships faster, and after careful calculation, it can also provide more transportation capacity faster.

The tugboat was equipped with a high-horsepower engine as the main power, and two lower-horsepower engines as auxiliary power and backup engines when necessary. Like Lin Zhenkang's boat, it uses three-machine and three-paddles.

Most of the reason why small boats use multiple oars is to prevent unexpected situations. Unfortunately, in the end, the situation occurred in an unexpected place. However, after investigation, the Lin family still recognized and accepted the ship. Many of them have been built and put into use.

The reason for being scolded is that one is implicated and dragged down, and the other is that some people are targeted, slandered, and thrown dirty water. Who is it? In fact, you can tell from the words used in limericks. Silly bags and candies are basically used in Sichuan and Chongqing.

There are a large number of poor people from Sichuan and Chongqing who are working here to make a living. Li Qin and the people are all working on this boat. Minxian is considered to have threatened their jobs. Of course, it is definitely not them who are slandering and throwing dirty water, but those who claim to be talking for them.

Those who say this are either stupid or bad. The Lin family is doing incremental growth, and this move can greatly increase the number of navigation in the Three Gorges. Once the shipping volume increases, the loading and unloading, freight and even the built factories can bring a lot of employment demand, and the demand for catering and other services can provide more opportunities for making a living. Many people at least don’t have to squeeze in here to pull the fiber, instead of finding other ways out like now.

Back to the topic, the tow barge fleet that Lin Mo encountered on the road was on both sides of the fleet, and the small boat with a slightly smaller shape and no coal burning boat was designed and built by Li Qinjun.

The one who towed the fleet first was that it lengthened the original tug, so it was a bit strange to look at the two. After the ship replaced the main engine with a coal-burning high-power steam engine, the fuel was replaced with coal, mainly to reduce costs for long-range towing. The ship was modified in a hurry. After accumulating some experience in use, a new ship model will be designed that is more suitable for this work.

As for the barge, it was the batch of ships designed and built by Sun Shanming. Li Qinjun was also responsible for cleaning up the mess, mainly three factory directors. He was reliable. As for other great people with more prominent titles, the Lin family was a little scared after Sun Shanming's incident, but they were all sent to the aftermath team. They tried the quality first to avoid making jokes when they joined the company in the future.

After some discussion, these people finally agreed that the only way to change the formed ship to a barge, move the control room, cabin, etc. on the bow side to the stern side, and cut off the section of the bow.

The ship was shortened, and its performance was optimized and improved in all aspects, which was more suitable for domestic channel needs. At the same time, a set of rudder wing systems that can greatly increase stability and resist wave rod performance were used. After some modification, the ship could basically drive normally in most inland waters in China.

The cabin changed to the stern of the boat only retains a low-horsepower engine, uses stopping brakes, maneuvering in and out at the docks, and maneuvering slowly and short distances alone in calm waters, etc., to remove high-horsepower engines, mainly to reduce weight and adjust the waterline of the ship's center of gravity.

The only engine was left behind by Li Qinjun's repeated insistence. The angle is exactly the same as designing and building a towboat. The retaining of a small number of moving boats can make the barge more widely applicable, such as brake stops, entry and exit of the dock.
