[0002] A life raft refers to a non-self-propelled boat for life-saving on a ship. A certain amount of food and fresh water are provided in the life raft for the crew to use when drifting at sea waiting for rescue. Life rafts can be divided into two categories: rigid life rafts and inflatable life rafts according to their structural forms.

[0003] In the existing production and manufacturing process of inflatable life rafts, a detection device is needed to detect the watertightness of the life raft to ensure that the life raft will not leak during use and has good watertightness. The existing devices for detecting the watertightness of life rafts often use a fixed structure to fix the entire life raft, and then submerge the life raft in water to observe whether there are bubbles on the water surface to detect the watertightness of the life raft. However, the existing fixed structures for fixing life rafts are all bolt-locked and fixed, and the position of the fixed structure cannot be adjusted, so that only life rafts of one specification can be fixed, and the practicability is relatively low. Content of the Utility Model

The column of the connecting column movably penetrates the wall of the detection pool, and the two ends of the column of the connecting column are respectively fixedly connected to one side wall of the moving plate and one side wall of the L-shaped plate.

[0007] Preferably, the driving assembly includes a driving rod, a rotating wheel, fixing plates, belt pulleys, and a belt. There are two fixing plates, and the two fixing plates are symmetrically and fixedly installed on the front side wall of the detection tank. Both ends of the rod body of the driving rod penetrate through the plate bodies of the fixing plates on both sides, and the connection between the driving rod and the fixing plates is connected by bearings.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3, the present utility model provides a technical solution: a life raft watertightness detection device, including a detection pool 1. There are four L-shaped plates 11, which are respectively located at the four corners of the inner cavity of the detection pool 1. A vertical groove 13 is opened on one side wall of the L-shaped plate 11. The bottom rod body of the screw rod 14 is installed on the bottom wall of the groove cavity of the groove 13 through a bearing, and its top rod body penetrates through the top wall of the groove 13 through a bearing. A moving block 15 adapted to the groove cavity of the groove 13 is screwed on the rod surface of the screw rod 14. A clamping plate 12 is welded on one side wall of the moving block 15. A knob block 16 is welded on the top rod body of the screw rod 14. The purpose is to drive the screw rod 14 to rotate by screwing the knob block 16. Then, under the matching action of the groove 13 and the moving block 15, the moving block 15 rises or falls along the rod body of the screw rod 14, thereby driving the clamping plate 12 to lift, and then the adjustment can be realized, clamping and fixing life rafts of different thicknesses, and improving the practicability. The adjustment component is used to adjust the distance between the L-shaped plates 11 on the left and right sides, and the driving component is used to drive the adjustment component to operate. The adjustment component includes a moving plate 5, a threaded rod 7, a guide rod 8, and a connecting column 17. There are two threaded rods 7 and two guide rods 8. The two threaded rods 7 are respectively rotatably installed on the left and right side walls of the front end of the pool body of the detection pool 1 through bearings, and the two guide rods 8 are respectively welded on the left and right side walls of the rear end of the pool body of the detection pool 1. The front end plate body of the moving plate 5 is screwed on the rod surface of the threaded rod 7, and the rear end plate body of the moving plate 5 is movably sleeved on the rod surface of the guide rod 8. The purpose is to limit and guide the moving plate 5 through the guide rod 8, so that the threaded rod 7 can drive the moving plate 5 to move left and right during rotation. The column body of the connecting column 17 movably penetrates through the wall body of the detection pool 1, that is, the connecting column 17 can move along the wall body of the detection pool 1. And the two end column bodies of the connecting column 17 are respectively welded on one side wall of the moving plate 5 and one side wall of the L-shaped plate 11. The purpose is to enable the moving plate 5 to drive the L-shaped plate 11 to move simultaneously during movement.

There are two fixing plates 4, and the two fixing plates 4 are symmetrically welded on the front side wall of the detection pool 1. The left and right ends of the rod body of the driving rod 2 respectively penetrate through the plate bodies of the left and right fixing plates 4. The connection between the driving rod 2 and the fixing plate 4 uses a bearing connection. The runner 3 is welded on the middle rod surface of the driving rod 2, so that when the runner 3 rotates, the driving rod 2 can be driven to rotate. The pulleys 9 are fixedly installed at the left and right end portions of the rod body of the driving rod 2 and the end portions of the rod body of the threaded rod 7. The belt 10 is connected to the adjacent pulleys 9. By driving the driving rod 2 to rotate through the runner 3, under the transmission effect of the pulleys 9 and the belt 10, the driving rod 2 drives the threaded rod 7 to rotate together during rotation. Then, under the action of the guide rod 8, the moving plate 5 can drive the L-shaped plate 11 to move under the action of the connecting column 17, and then the distance between the L-shaped plates 11 on the left and right sides can be adjusted, so that life rafts of different widths can be placed in the detection pool 1, improving the practicability.

[0019] A water inlet pipe 6 is connected to the upper right side wall of the detection pool 1, and a drain pipe 18 is connected to the lower left side wall of the detection pool 1. By providing the water inlet pipe 6 and the drain pipe 18, it is convenient to add water to the detection pool 1.
