[0022] When in use, the self-locking universal wheel 19 can be used to conveniently move and fix the position of the device, thereby improving the flexibility of the device. In addition, by starting the driving device 15, the driving device 15 drives the winding roller 16 to rotate, and the rotation of the winding roller 16 can drive the rope 17 to move upward, thereby driving the cross plate 3, the hook 11 and the seawater filter 12 to move upward.

[0023] As a further implementation of this embodiment, Figure 1-Figure 4 As shown, both sides of the bracket 1 are provided with limit grooves 2, and the limit grooves 2 cooperate with the limit blocks 4 on both sides of the cross plate 3. A pair of fixed plates 5 are fixedly connected to the lower end of the cross plate 3, and a rotating handle 6 is arranged on one side of the fixed plate 5. One end of the rotating handle 6 passes through the fixed plate 5 and is fixedly connected to the bidirectional screw rod 7. One end of the bidirectional screw rod 7 is rotatably connected to the fixed plate 5. A pair of connecting blocks 8 are threadedly connected on the bidirectional screw rod 7. A limit rod 9 is fixedly connected between the two fixed plates 5, and the limit rod 9 passes through the connecting block 8. The limit rod 9 can limit the connecting block 8. A threaded rod 10 is fixedly connected to the lower end of the connecting block 8. The threaded rod 10 is threadedly connected to the threaded hole at the end of the hook 11, and the hook 11 cooperates with two ears 13 on the seawater filter 12.

[0024] When in use, by rotating the rotating handle 6, the rotating handle 6 can drive the bidirectional screw rod 7 to rotate, and the rotation of the bidirectional screw rod 7 drives the two connecting blocks 8 to move toward each other. The connecting block 8 is more stable in the process of moving under the limiting action of the limiting rod 9, and the two connecting blocks 8 can drive the two hooks 11 to move, so that the distance between the two hooks 11 can be adjusted, which is convenient for hoisting seawater filters 12 of different sizes.

When the hook 11 is hung on the lifting ear 13, the driving device 15 is started, and the driving device 15 drives the winding roller 16 to rotate, and the winding roller 16 rotates. The movement can drive the line 17 to move upward, and then drive the cross plate 3 and the limit block 4 to move upward. Under the limiting effect of the limit groove 2, the movement of the cross plate 3 can be more stable. The movement of the cross plate 3 can indirectly drive the hook 11 and the seawater filter 12 to move and lift, so that it is more convenient to repair the seawater filter 12. The seawater filters 12 of different sizes can be lifted by the device. At the same time, the hook 11 on the threaded rod 10 can be removed from the threaded rod 10 by rotating the hook 11, which is convenient for replacing the hook 11 according to the size of the lifting ear 13, and the seawater filter 12 can be stably lifted and moved upward.
