A tracked underwater dredging robot

Abstract

This utility model discloses a tracked underwater dredging robot, belonging to the field of dredging robot technology. It includes a dredging robot body with tracks at both ends. A pump body is located on one side of the upper end of the dredging robot body, with a discharge pipe at the upper end of the pump body. A connecting pipe is located at one end of the pump body, and a bucket is located at the other end of the connecting pipe. By setting a clamping component, when the dredging robot body enters the pool bottom and moves to the slope of the pool bottom, the fixed rods on both sides of one end of the bucket rotate in a fixed seat via a rotating shaft. The rotation of the rotating shaft causes a sliding plate to slide on an arc-shaped rod. The sliding plate compresses the spring on the arc-shaped rod, thereby allowing the lower end of the bucket to clamp against the pool bottom. Fixed stops on both sides of one end of the fixed seat limit the swing of the bucket. The clamping component ensures that the lower end of the bucket clamps against the pool bottom, preventing gaps between the lower end of the bucket and the pool bottom due to the slope of the pool bottom, which would affect the dredging effect.

Description

Technical Field

[0001] This utility model belongs to the field of dredging robot technology, specifically relating to a tracked underwater dredging robot. Background Technology

[0002] Dredging robots are intelligent devices specifically designed for cleaning silt and debris from waterways or pipelines. They are primarily used in river management, municipal pipeline dredging, and industrial tank cleaning. Tracked underwater dredging robots are remotely controlled or autonomous underwater robots that use a tracked mobile chassis to navigate complex underwater environments such as rivers, lakes, reservoirs, ports, and ponds. They use onboard suction or excavation devices to clean and transport bottom mud, sediment, and pollutants.

[0003] The existing tracked underwater dredging robot's bucket does not have a clamping function. When dredging a pool with a slope, the bucket cannot always be pressed firmly against the bottom, resulting in poor dredging effect. At the same time, the existing tracked underwater dredging robot is not convenient for disassembling and assembling the filter plate, and the filter plate is prone to clogging after long-term use.

Both gear 295 and gear 296 are located inside the protective box 291.

[0019] By adopting the above technical solution, when dredging, the motor 293 is turned on to drive the active crushing roller 292 to rotate. The rotation of the active crushing roller 292 drives the driven crushing roller 294 to rotate in opposite directions through gear 1 295 and gear 2 296. The rotation of the active crushing roller 292 and the driven crushing roller 294 in opposite directions can crush larger impurities in the sludge sucked into the bucket 6, avoiding blockage of the connecting pipe 5 caused by larger impurities.

[0024] Specifically, the sides of the active crushing roller 292 and the driven crushing roller 294 are tangent to the inner wall of the bucket 6, and a rubber sealing ring is provided at the connection between the protective box 291 and the bucket 6.

[0025] By adopting the above technical solution, the sides of the active crushing roller 292 and the driven crushing roller 294 are prevented from scraping against the inner wall of the bucket 6, and the rubber sealing ring is set to make the sealing between the protective box 291 and the bucket 6 better.

[0026] In this embodiment, the filter assembly 3 includes a filter box 31. The filter box 31 is located in the middle of the connecting pipe 5. The filter box 31 contains a filter plate 33. The upper part of the filter box 31 has a slot 38 corresponding to the filter plate 33. A sealing plate 32 is provided on one side of the filter box 31. Insert plates 34 are symmetrically fixed on one side of the sealing plate 32. A slot 35 corresponding to the insert plate 34 is provided on one side of the filter box 31.

[0028] By adopting the above technical solution, the sealing plate 32 fits more closely to the filter box 31 after installation, and no gaps are generated between the side of the filter plate 33 and the inner wall of the filter box 31 after the filter plate 33 is installed in the filter box 31.

[0029] In this utility model, the motor 293 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0030] The structure and working principle of the dredging robot body 1, discharge pipe 4, connecting pipe 5, bucket 6, pump body 7 and walking track 8 of this utility model have been disclosed in a tracked underwater dredging robot disclosed in Chinese Patent Publication No. CN114855912A.

[0031] The working principle and usage process of this utility model are as follows: When using the tracked underwater dredging robot, the robot is placed in a suitable position. The robot body 1 moves via the walking tracks 8. The pump body 7 is activated to suck up the sludge through the connecting pipe 5 and the bucket 6, and discharges the sludge through the discharge pipe 4. After the robot body 1 enters the bottom of the pool, when it moves to the bottom slope, the two fixed rods 22 on both sides of one end of the bucket 6 rotate in the fixed seat 21 via the rotating shaft 23. The rotating shaft 23 rotates... The sliding plate 26 slides on the arc-shaped rod 25, and the sliding plate 26 compresses the spring 27 on the arc-shaped rod 25, so that the lower end of the bucket 6 can be pressed against the bottom of the pool. The fixed stops 28 on both sides of one end of the fixed seat 21 can limit the swing of the bucket 6. By setting the pressing component 2, the lower end of the bucket 6 can be pressed against the bottom of the pool, avoiding the possibility of gaps between the lower end of the bucket 6 and the bottom of the pool due to the existence of a slope in the pool bottom, which would affect the dredging effect. By setting the crushing component 29, when dredging is carried out, the motor 293 is turned on to drive the active crushing roller 292 to rotate, actively The rotation of crushing roller 292 drives driven crushing roller 294 to rotate in opposite directions via gear 295 and gear 296. The rotation of driven and driven crushing rollers 292 and 294 in opposite directions crushes larger impurities in the sludge sucked into bucket 6, preventing blockage of the connecting pipe 5. Crushing component 29 provides better crushing effect for larger impurities. During sludge removal, the sludge enters filter box 31, where filter plate 33 filters out larger impurities. When cleaning filter plate 33 is required, [the filter plate 33 should be removed]. The fixing bolt 36 is unscrewed from the fixing hole 37 of the insert plate 34, and the sealing plate 32 can be removed from the front end of the filter box 31. The insert plate 34 at one end of the sealing plate 32 is removed from the slot 35 at the front end of the filter box 31. Then the filter plate 33 can be removed from the slot 38 of the filter box 31, and the inside of the filter box 31 and the filter plate 33 can be cleaned. By setting the filter assembly 3, larger impurities in the sludge can be filtered, and the filter plate 33 can be easily disassembled and cleaned, avoiding clogging of the filter plate 33 after long-term use.
