[0031] Reference Figure 2 and Figure 3 The recovery device 9 includes a reeling rod 91, a storage chamber is provided in the floating body 1, the reeling rod 91 is rotatably provided in the storage chamber, one end of the reeling rod 91 is fixedly connected to the unit bar 81, and one end of the unit bar 81 away from the reeling rod 91 is fixedly connected to the anchor 3 connected to the wire rope 2, and a linkage device 10 is provided between the reeling rod 91 and the driving shaft 41, and the linkage device 10 is used to make the driving shaft 41 drive the reeling rod 91 to rotate; the linkage device 10 includes a driving sprocket 101, a driven sprocket 102 and a chain 103, and the driving sprocket 101 and the driven sprocket 102 are connected to the reeling rod 91. The driving shaft 41 is fixedly connected, the driven sprocket 102 is fixedly connected to the winding rod 91, and the chain 103 is sleeved between the driving sprocket 101 and the driven sprocket 102. The driving sprocket 101 drives the driven sprocket 102 to rotate through the chain 103. In this embodiment, the driven sprocket 102 is preferably a one-way sprocket, that is, the driven sprocket 102 can drive the winding rod 91 to rotate synchronously for winding. When the anchor drives the unit bar 81 to slide when sinking, the unit bar 81 drives the winding rod 91 to rotate, and the winding rod 91 will not drive the driven sprocket 102 to rotate.

[0032] The implementation principle of the equipment for cleaning water plants in rivers and lakes according to the embodiment of the present application is as follows: when it is necessary to raise the anchor 3, the winding device on the hull is started to drive the wire rope 2 to drive the anchor 3 to rise, and at this time, the driving member 40 is synchronously started to rotate, and the driving member 40 rotates to drive the driving shaft 41 to rotate, and the driving shaft 41 drives the driven shaft 42 to rotate through the conveyor belt 43. At the same time, the driving shaft 41 rotates to drive the driving sprocket 101 to rotate, and the driving sprocket 101 rotates to drive the driven sprocket 102 to rotate through the chain 103, and the driven sprocket 102 drives the winding device. The winding rod 91 rotates, and the winding rod 91 rotates to wind up the unit bar 81 on the winding rod 91. As the anchor 3 and the anti-entanglement sleeve 8 rise, the water plants wrapped on the anti-entanglement sleeve 8 gradually approach the floating body 1. As the two winding rods 91 are wound, the two unit bars 81 are gradually separated. At this time, the first magnet 201 and the second magnet 202 are separated from each other, so that the elastic rod 30 in the arc shape is restored to a straight rod state, thereby driving the unit bar 81 to return to a straight state, so that the winding rod 91 can wind up the unit bar 81.

[0033] As the two unit bars 81 separate, the water plants wrapped around the outside of the two unit bars 81 are grabbed by the grabbing claws 44 on the conveyor belt, and the two symmetrically arranged stripping devices 4 simultaneously apply opposite forces to the wrapped water plants, thereby tearing the water plants apart so that the water plants are no longer wrapped around the anti-winding sleeve, and the conveyor belt 43 drives the grabbing claws 44 to move to the fixed fence 6, and as the grabbing claws 44 and the cutters 7 on the fence rod 61 intersect with each other, the water plants on the grabbing claws 44 are cut into several fragments, so that the water plants are separated from the grabbing claws 44, so that the grabbing claws 44 can continue to grab new water plants.

[0034] When it is necessary to release the anchor 3 downward, the winding device on the hull is started to rotate in the opposite direction. Under the action of the gravity of the anchor 3, the anchor 3 drives the steel wire rope 2 to slide downward, and at the same time, the anchor 3 drives the unit bar 81 to slide downward. As the two unit bars 81 slide downward and gradually approach each other, under the mutual attraction of the first magnet 201 and the second magnet 202, the two elastic rods 30 are bent in the direction of approaching each other, so that the first magnet 201 and the second magnet 202 are attracted by magnetic force, so that the two unit bars 81 are wrapped around the outside of the steel wire rope 2 to prevent water plants from being entangled on the steel wire rope 2; at the same time, as the unit bar 81 slides downward, the unit bar 81 drives the winding rod 91 to rotate in the opposite direction, and the winding rod 91 cannot drive the driven sprocket 102 to rotate, and there is no need to start the stripping device 4 at this time.

[0035] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
