In the face of today's shift from high-power and high-consumption traditional machinery to clean and simple equipment, and the increasing investment in the offshore engineering industry, more and more investors have turned their attention to various supporting equipment for the offshore industry. Influenced by the current rising manufacturing industry, the use of thruster covers in the field of shipbuilding and offshore engineering has become more and more widespread.
[0003] Most of the existing ship thrust covers are exposed on the outside of the hull. During the ship's travel, the exposed thrust covers will increase the water resistance of the ship, increase the energy consumption of the ship, and do not conform to the development concept of energy conservation and emission reduction.

A square groove 1 is opened on the left side of the side thrust cover 4, and the inner wall of the square groove 1 is slidably connected to the right side of the sliding block 226. By setting the thrust cover assembly 22, specifically, the movement of the moving block 222 will drive the fixed block 223 to move to the right, so that the sliding block 226 moves in the square groove 1 opened inside the side thrust cover 4. When the moving block 222 moves to the far right, the right side of the side thrust cover 4 will overlap with the outer surface of the outer wall 3 of the ship, thereby reducing the resistance encountered by the ship during driving and reducing the energy consumption of the ship during driving.
[0029] The bottom of the hollow frame 11 is fixedly connected to the top of the side push box 2. A circular groove 1 is opened inside the hollow frame 11. A threaded rod 15 is rotatably connected to the inner wall of the circular groove 1. A motor 12 is fixedly connected to the left side of the hollow frame 11.
[0030] The right output end of the motor 12 is fixedly connected to the left side of the threaded rod 15, and the outer surface of the threaded rod 15 is threadedly connected to a moving block 13. The front and back sides of the moving block 13 are fixedly connected to a moving frame 14, and the sides of the two moving blocks 222 that are away from each other are fixedly connected to the side of the moving frame 14 close to the round rod 221.

The parts contained in the two decompression assemblies 33 are the same. The decompression assembly 33 includes a second sliding block 331, and a square groove 2 is opened on the left side of the side push cover 4.

[0034] A specific application of this embodiment is: when the ship completes the steering, the motor 12 is turned on to drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, the moving block 13 is driven to move to the right. During the movement of the moving block 13, the front and back moving frames 14 are driven to move to the right. During the movement of the moving frame 14, the moving block 222 is driven to move to the right on the outer surface of the round rod 221. When the moving block 222 moves, the fixed block 1 223 is driven to move to the right. During this process, the rotating rod 224 is rotated in the inner wall of the fixed block 1 223 and the sliding block 1 226, so that the sliding block 1 226 moves in the square groove 1 inside the side thrust cover 4, driving the side thrust cover 4 to rotate toward the inside of the side thrust box 2. When the moving block 222 moves to the far right, the right side of the thrust cover 4 will overlap with the outer surface of the outer wall 3 of the ship, reducing the resistance encountered by the ship during driving and reducing the energy consumption of the ship during driving. The limit block 225 will contact the front of the fixed block 1 223, and the rotating rod 224 cannot continue to rotate clockwise, so that the thrust cover 4 will not be opened due to the pressure of the external water flow. In this process, the spring 335 will elastically push the sliding rod 333 to move toward the side close to the rotating block 332, so that the rotating block 332 drives the sliding block 2 331 to move in the inner wall of the square groove 2 opened inside the thrust cover 4, so that the thrust cover 4 can share the pressure on the rotating rod 224 when closed, thereby improving the service life of the parts inside the device.
