[0003] The balance state of traditional civilian ships in lakes is very easily affected by water fluctuations. Sometimes in rainy weather, the water fluctuations are relatively large. Since the length of the ship is much greater than its width, the rolling shake is usually more serious than the pitching shake, which may cause the hull to capsize and then sink into the water. Summary of the invention

[0004] The object of the present invention is to provide a polyethylene ship and a ship anti-tilt component to solve the problem mentioned in the above background technology that the balance state of traditional civilian ships in lakes is very easily affected by water flow fluctuations. Sometimes in rainy weather, the water flow fluctuations are relatively large. Since the length of the ship is much larger than the width of the ship, the rolling shake is usually more serious than the pitching shake, which may cause the hull to capsize.

[0014] Technical effects and advantages of the present invention:

[0015] The polyethylene ship and the ship anti-tilt assembly are provided with air bags respectively installed on both sides of the polyethylene hull. When the polyethylene hull tilts to one side, the dual-axis motor located on the side works to drive the two guide blocks to move toward each other, and cooperates with the push-pull rod to drive the protection box to descend, thereby driving the air bag to descend into the water, increasing the buoyancy of one side of the polyethylene hull, and quickly resetting the polyethylene hull, so that the polyethylene hull maintains a balanced state;

After the polyethylene hull docks, the fixing plate and the fixing box are moved toward each other. At the same time, the rotating motor drives the reel to rotate, automatically reeling the airbag, discharging the gas in the airbag, and reeling the airbag to avoid damage to the airbag due to being exposed to the outside and hit by foreign objects;

[0017] At the same time, during the process of rolling up the airbag, the sealing sleeve can scrape off the water stains on the surface of the airbag, making the airbag drier, avoiding the corrosion of the airbag by impurities in the water, and extending the service life of the airbag;

[0018] The fixing ring is supported by a fixing spring so that the two fixing pins are respectively inserted into the fixing holes of the two connecting blocks, so that the installation and fixation of the fixing plate and the fixing box can be quickly completed. At the same time, the fixing pin is pulled to separate the fixing pin from the connecting block, and the fixing plate and the fixing box can be disassembled, thereby facilitating the disassembly and maintenance of the airbag. The polyethylene ship and the ship anti-tilt component can quickly correct the position of the polyethylene hull after it tilts, so that it can quickly maintain a balanced state.

[0037] Working principle:

[0038] When the polyethylene ship and the ship anti-tilt assembly are in use, when the polyethylene hull 1 tilts to one side, the dual-axis motor 4 located on the side works to drive the two guide blocks 7 to move toward each other, and cooperates with the push-pull rod 8 to drive the protection box 10 to descend, thereby driving the airbag 25 to descend into the water, increasing the buoyancy of one side of the polyethylene hull 1, and quickly resetting the polyethylene hull 1, so that the polyethylene hull 1 maintains a balanced state;

[0039] When the polyethylene hull 1 docks, the control valve on the vent pipe 27 is opened, the forward and reverse motors 12 are started, and the two connecting blocks 15 are driven to move toward each other at the same time, so that the fixing plate 17 and the fixing box 18 move toward each other, and the rotating motor 22 is started at the same time to drive the winding disk 23 to rotate, and the airbag 25 is automatically wound to discharge the gas in the airbag 25. After the airbag 25 is wound on the outside of the winding disk 23, the fixing plate 17 and the fixing box 18 are fitted to avoid damage to the airbag 25 due to the impact of foreign objects when the airbag 25 is exposed to the outside. At the same time, in the process of winding the airbag 25, the sealing sleeve 26 scrapes off the water stains on the surface of the airbag 25 to make the airbag 25 drier, avoid corrosion of the airbag 25 by impurities in the water, and extend the service life of the airbag 25.
