[0057] The driving motor 64 works to make the threaded rod 61 rotate, the threaded rod 61 drives the first sliding block 62 to rotate through the gear 63, so that the first sliding block 62 is driven to move in the inside of the mobile box 1, compared with the prior art, the first sliding block 62 of the present application can reciprocate in one direction in the inside of the mobile box 1, so that the gravity center of the mobile box 1 is changed.

[0058] Referring to Figure 4 , Figure 9 and Figure 10As shown in the figure: the gravity center adjusting assembly 6 further comprises a first guide rod 65 and a connecting plate 66, the first guide rod 65 is fixedly arranged in the interior of the moving box 1, the axis of the first guide rod 65 is parallel to the axis of the threaded rod 61, the first sliding block 62 is slidably arranged on the first guide rod 65, the connecting plate 66 is fixedly connected with the two first sliding blocks 62, the driving motor 64 is fixedly arranged at the lower center of the connecting plate 66, and the water blocking assembly 7 is provided with two output ends, and the connecting plate 66 is between the two output ends of the water blocking assembly 7.

[0062] As shown in the figure Figure 4 , Figure 9 and Figure 10 : the gravity center adjusting assembly 6 further comprises a second guide rod 67, the second guide rod 67 is fixedly arranged in the interior of the moving box 1, the axis of the second guide rod 67 is parallel to the axis of the first guide rod 65, the second guide rod 67 is slidably connected with the connecting plate 66, and the second guide rod 67 is slidably connected with the two output ends of the water blocking assembly 7.

[0063] When the moving box 1 swings with waves on the sea surface, the connecting plate 66 and the two output ends of the water blocking assembly 7 always remain on the same straight line, compared with the prior art, the second guide rod 67 of the present application limits the position of the connecting plate 66 and the two output ends of the water blocking assembly 7, thereby ensuring that the connecting plate 66 can stably contact the two output sections of the water blocking assembly 7 when moving.

[0064] As shown in the figure Figures 4 to 10As shown: the water blocking assembly 7 includes a fixed frame 71, a second sliding block 72, a third sliding block 73 and a limiting strip 74, the fixed frame 71 is elastically connected with the moving box 1, the fixed frame 71 moves along the height direction of the moving box 1, the second sliding block 72 is slidably connected with the second guide rod 67, both ends of the connecting plate 66 are provided with a second sliding block 72, the sliding direction of the second sliding block 72 is parallel to the axis of the second guide rod 67, the third sliding block 73 is slidably arranged along the height direction of the moving box 1, the second sliding block 72 and the third sliding block 73 are connected through a hinged rod, the limiting strip 74 is slidably arranged along the connecting direction of the two floats 11, the limiting strip 74 is hinged with a third sliding block 73 through a hinged rod, and the fixed frame 71 is provided with a limiting hole 711 matched with the limiting strip 74.

[0065] Initially, the elastic connection between the fixed frame 71 and the moving box 1 is in a tight state, when the connecting plate 66 moves away from the center of the moving box 1, the connecting plate 66 moves to push the second sliding block 72 to move along the axis direction of the second guide rod 67, the second sliding block 72 moves to drive the third sliding block 73 to move along the vertical direction of the moving box 1, the third sliding block 73 moves to drive the limiting strip 74 to move, so that the limiting strip 74 is separated from the limiting hole 711, and the fixed box moves along the height direction of the moving box 1. Compared with the prior art, the fixed frame 71, the second sliding block 72, the third sliding block 73 and the limiting strip 74 of the present application can temporarily store seawater on the top surface of the moving box 1, so that the seawater flow can carry away the seaweed on the top surface of the moving box 1.

[0066] Referring to Figures 4 to 10 As shown: the water blocking assembly 7 further includes an elastic assembly 75, which is fixedly arranged between the third sliding block 73 and the moving box 1.

[0067] When the connecting plate 66 approaches the center of the moving box, the elastic assembly 75 will provide elastic force to push the third sliding block 73 back to the original position at this time in order to restore the state, and the second sliding block 72 returns to the original position with the movement of the third sliding block 73. Compared with the prior art, the elastic assembly 75 of the present application can automatically reset the limiting strip 74 when the center of gravity of the moving box 1 returns to the center, so that the whole device can be used repeatedly.

[0069] When the limiting strip 74 is disengaged from the limiting hole 711, the fixed frame 71 moves along the height direction of the moving box 1 by the elastic force, and the second limiting protrusion 13 contacts the end of the first limiting sliding groove 712 after the fixed frame 71 moves a certain distance, and the fixed frame 71 stops moving, compared with the prior art, the first limiting sliding groove 712 and the second limiting protrusion 13 of the present application limit the moving range of the fixed frame 71, thereby avoiding the fixed frame 71 from being disengaged from the connection with the moving box 1.

[0072] Referring to Figures 4 to 10 As shown: a second limiting sliding groove 14 is formed on the moving box 1 to limit the second sliding block 72 from approaching the center of the moving box 1.

[0073] When the connecting plate 66 is at the center of the moving box 1, the second sliding block 72 returns to the original position under the action of the elastic assembly 75, at this time, there is a certain gap between the second sliding block 72 and the connecting plate 66, compared with the prior art, the second limiting sliding groove 14 of the present application makes the connecting plate 66 move a certain distance to contact the second sliding block 72, thereby avoiding the fixed frame 71 from moving upward first to prevent the top surface of the moving box 1 from being immersed in the sea surface.
