[0002] Currently, the main method for dredging small and medium-sized water bodies is to drain the water and then use excavators or dredging machines to carry out dredging work directly in the absence of water. This method requires diverting the river and sometimes even has to excavate temporary channels. The workload is large and complicated, and the dredging site cannot be used for production for a long period of time, resulting in certain economic losses. Therefore, this method has low production efficiency, high labor intensity, and is primitive. Moreover, in many cases, due to the depth of the riverbed and the terrain, it is impossible to use large-scale engineering machinery for mechanized operations.

[0003] There are also underwater sludge suction equipment used for underwater work. Existing underwater sludge suction equipment generally moves through a tracked structure. However, the tracked structure is relatively simple. When the underwater sludge is shallow, rocks or other objects on the bottom will be exposed. The tracked structure often loses its grip due to these protruding parts, making it difficult for the equipment to move and affecting the sludge removal efficiency. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: an underwater dredging robot, comprising a main body 1 and two tracked mechanisms 2; Two track mechanisms 2 are respectively located on both sides of the main body 1 of the device, and an extraction structure is provided on the top of the main body 1 of the device. Both track mechanisms 2 have the same structure. One track mechanism 2 includes a front support wheel 21 that is laterally rotatably connected to the front end of the device body 1. A motor is fixedly connected to the rear end of the same side surface of the device body 1. A rear support wheel 22 is fixedly connected to the outer end of the output shaft of the motor. Multiple vertically movable lower support wheels 212 are provided on the lower part of the same side surface of the device body 1. Tensioning wheels 210 are provided on both sides of the multiple lower support wheels 212 on the same side surface of the device body 1. A driven track 213 is sleeved on the outside of the front support wheel 21, the rear support wheel 22, the multiple lower support wheels 212 and the two tensioning wheels 210.

[0016] The outer surface of the driven track 213 is provided with anti-slip texture.

[0017] In this embodiment, when the device is performing underwater dredging operations, it is driven to move by the track mechanisms 2 on both sides. The track mechanisms 2 of the device are equipped with multiple vertically movable lower support wheels 212. When moving in places with protrusions such as rocks on the bottom of the water, the movable lower support wheels 212 can ensure that the track has a certain bending deformation space, so as to adapt to the uneven riverbed environment, ensure the movement capability of the device, and thus indirectly improve the dredging efficiency of the device.

[0018] Furthermore, the outer surfaces of the front support wheel 21 and the rear support wheel 22 are provided with a plurality of toothed grooves 214 along their circumferential direction, and the inner surface of the driven track 213 is provided with a toothed belt 215 that is adapted to the plurality of toothed grooves 214.

[0019] In this embodiment, the motor drives the rear support wheel 22 to rotate, and the toothed grooves 214 on the outer surface of the rear support wheel 22 will drive the driven track 213 to move through the toothed belt 215, thereby driving the track mechanism 2 as a whole to move.

[0020] Furthermore, a plurality of vertically arranged grooves 26 are provided on the lower part of the outer surface of the main body 1 of the device. Each groove 26 has a movable block 27 vertically slidably connected inside. A compression spring 28 is fixedly connected between the top of the movable block 27 and the top of the groove 26. A lower wheel axle 211 is horizontally fixedly connected to the outer surface of each movable block 27. A plurality of lower support wheels 212 are rotatably connected to the outer surface of the lower wheel axle 211 and located on both sides of the toothed belt 215.

[0021] In this embodiment, when the device moves on the riverbed, when it reaches a riverbed with protruding rocks, the protruding part of the rocks will lift up that part of the driven track 213, and the lower support wheel 212 at the current position will also move upward a certain distance accordingly. However, under the action of the compression spring 28, the lower support wheel 212 will apply pressure to the driven track 213, so that its lower surface always adheres to the rocks, thereby improving the grip of the device when moving on the riverbed and ensuring the device's mobility.

[0022] Furthermore, inclined grooves 23 are provided on the outer surface of the main body 1 and on both sides of the multiple vertical grooves 26. Slider 24 is slidably connected inside the multiple inclined grooves 23 along its length. Tension springs 25 are fixedly connected at both ends of the two sliders 24 between the top and bottom ends inside the two inclined grooves 23, respectively. Wheel axles 29 are fixedly connected laterally to the outer surface of the two sliders 24. Multiple tension wheels 210 are rotatably connected to the outer surface of the two wheel axles 29 and located on both sides of the toothed belt 215.

[0023] In this embodiment, the tension wheel 210 can provide a tensioning effect. When the driven track 213 deforms, the slider 24 will move accordingly to change the position of the tension wheel 210, thereby ensuring that the driven track 213 always remains in a tensioned state and will not detach from the structure.

[0024] Furthermore, the extraction structure includes a mounting base 3 fixedly connected to the upper surface of the device body 1. A connecting tube 4 is fixedly connected inside the mounting base 3. The front end of the connecting tube 4 extends to the lower part of the front of the device body 1. A suction nozzle 5 communicating with the front end of the connecting tube 4 is fixedly connected to the bottom of the front end of the connecting tube 4.

[0025] In this embodiment, the top end of the connecting pipe 4 is connected to an external extraction pump or other extraction structure. The extraction structure generates suction to extract the silt from the riverbed through the suction nozzle 5 and the connecting pipe 4.

[0026] The working principle and usage process of this utility model: After the utility model is installed, when the device is performing underwater dredging operations, it is driven to move by the track mechanism 2 on both sides. The track mechanism 2 of the device is equipped with multiple vertically movable lower support wheels 212. When moving in places with protrusions such as rocks on the bottom of the water, the movable lower support wheels 212 can ensure that the track has a certain bending deformation space, so as to adapt to the uneven riverbed environment, ensure the movement capability of the device, and thus indirectly improve the dredging efficiency of the device.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
