[0026] The driving assembly includes a rotating shaft 25, which is rotatably installed below the frame 1. The rotating shaft 25 is connected to the motor 12 through a connecting assembly. A half gear 26 is fixedly sleeved outside the rotating shaft 25. A rack 27 is fixedly installed above the support frame 20, and the rack 27 is meshed with the half gear 26.

[0029] Furthermore, the moving mechanism includes a push plate 13 and a push block 14. The push block 14 is fixedly installed above the processing part 17.

[0030] Specifically, the power structure includes a slide rod 15, both ends of which are fixedly mounted with support plates 16, the support plate 16 is slidably connected to the frame 1, the slide rod 15 is slidably connected to the push block 14, and the outer movable sleeve of the slide rod 15 is provided with a No. 1 spring 19, and the No. 1 spring 19 is fixedly connected to the push block 14.

[0031] Working principle: the frame 1 falls into shallow waters, and the processing component 17 contacts the bottom of the water. Under the action of gravity, the frame 1 moves toward the direction of the processing component 17, and the frame 1 drives the push plate 13 to rotate. The push plate 13 drives the two groups of processing components 17 to move away from each other through the push block 14. The protrusion 18 contacts the garbage on the bottom of the water and drives the garbage on the bottom of the water to move synchronously. Moreover, the protrusion 18 will not drive the mud and sand on the bottom of the water to move when it moves. The processing component 17 slides on the outside of the slide rod 15 when it moves, and the No. 1 spring 19 is deformed by the force. At the same time, the support plate 16 slides inside the frame 1.

[0032] When the processing part 17 moves to a certain position, the processing part 17 stops moving, and the motor 12 is connected to an external power source. The motor 12 drives the second gear 11 to rotate. Since the first gear 8 and the second gear 11 rotate, the second gear 11 can rotate. Under the mutual cooperation of the groove body 9 and the protrusion 10, the second gear 11 drives the positioning pile 2 to rotate. The positioning pile 2 is threadedly connected to the frame 1. The positioning pile 2 can move downward and be inserted into the bottom of the water when rotating.

[0033] Under the action of the fixing frame 4, when the positioning pile 2 moves downward, the adjusting member 7 moves downward under the action of gravity. When the adjusting member 7 moves to a point where it is no longer in contact with the connecting member 6, the connecting member 6 can rotate above the column 3 through the connecting seat 5, so that the dredger can also move within a certain range when positioning.

[0034] At the same time, the motor 12 drives the No. 1 wedge 28 to rotate. Since one side of the No. 2 wedge 29 is inclined, the No. 1 wedge 28 can push the No. 2 wedge 29 into the inside of the groove 31 when rotating, and the shaft 25 does not rotate at this time.

[0035] When there is no need to position the dredger, the positioning pile 2 moves upward, and the No. 1 wedge 28 drives the No. 2 wedge 29 to move synchronously. At this time, the rotating shaft 25 can drive the half gear 26 to rotate, and the half gear 26 and the rack 27 are engaged, thereby driving the support frame 20 to slide on the outside of the guide rod 23, and the No. 2 spring 24 is deformed under the force, so that the brush 21 can clean the outer surface of the positioning pile 2 and remove the mud and sand attached to the outer surface of the positioning pile 2. When the half gear 26 rotates to no longer engage with the rack 27, under the elastic force of the No. 2 spring 24, the support frame 20 can be reset. At this time, the knocking piece 22 can knock on the positioning pile 2, so that the positioning pile 2 can vibrate, drive the water around the device to flow, and allow the organisms around the device to stay away from the device.
