Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a dredging device for water conservancy canals. Background Technology

[0002] As an important infrastructure for water resource allocation and flood control and drainage, the unobstructed flow of water canals is crucial for ensuring agricultural irrigation, urban water supply and flood control safety. However, over time, large amounts of silt, weeds and domestic waste tend to accumulate at the bottom and sides of the canals, seriously affecting their water conveyance capacity and service life. Traditional dredging methods mostly rely on manual labor or simple mechanical operations, which are not only labor-intensive and inefficient, but also pose safety hazards. Therefore, it is particularly important to develop an efficient and automated dredging device.

[0003] Referring to CN212715094U, a canal dredging device for water conservancy and hydropower construction includes a fixed plate, support rod, hydraulic push rod, collection box, connecting frame, scraper, sludge removal port, pipe, fixed box, threaded rod, sleeve, coupling, sludge pump, hydraulic cylinder, outer rod, inner rod, pressure plate, sleeve block, and baffle. This device has a reasonable structural design; the scraper facilitates the entry of sludge from the canal into the sludge removal port, the sludge pump delivers the sludge from the sludge removal port into the collection box, and the pressure plate, when lowered, squeezes the sludge, discharging water to reduce the sludge mass, thus facilitating sludge removal and treatment. This utility model's structure... The device features a compact design and adjustable sludge removal port height for easy dredging operations. The outer rod and sleeve work together to keep the sludge removal port stable during movement, reducing the impact of tilting on the dredging effect. The baffle moves left and right to reduce the accumulation of garbage on the water surface at the sludge removal port. As can be seen from the above, although this device can be used well, it is usually not convenient for crushing sludge, weeds, domestic waste and other materials at the bottom of the canal. It is difficult to cut the garbage at the bottom of the canal into small particles, which makes it difficult to pump and remove the garbage at the bottom of the canal, thus affecting the dredging effect and often troubling users. Utility Model Content

[0004] The purpose of this utility model is to provide a dredging device for water conservancy canals, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to crush and process silt, weeds, domestic waste and other materials at the bottom of the canal, and it is difficult to cut the garbage at the bottom of the canal into small particles, which makes it difficult to pump and remove the garbage at the bottom of the canal, thus affecting the dredging effect of the canal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dredging device for a water conservancy canal, comprising a top base, with lifting drive components on both sides of the bottom end of the top base, an inverted T-shaped bracket at the end of the lifting drive component away from the top base, universal wheels mounted on both sides of the bottom end of the inverted T-shaped bracket, a transmission seat on the surface of the top base, a rack on the surface of the transmission seat, guide rails on the top base surfaces at both ends of the rack, two rail seats slidably connected to the surfaces of the guide rails, and placement plates on the surfaces of several rail seats, the surfaces of the placement plates being connected by... The bracket has a component frame. A first motor is mounted on the inner wall of the upper end of the component frame via the bracket. A first rotating shaft is provided at the bottom end of the first motor. The bottom end of the first rotating shaft extends to the outside of the component frame. A second gear is fixed on the outer wall of the upper end of the first rotating shaft. A third gear is rotatably mounted on the bottom of the component frame on one side of the second gear. The third gear meshes with the second gear. A belt drive mechanism is provided at the top end of the third gear via a guide shaft. A second rotating shaft is provided on one side of the bottom end of the belt drive mechanism. The bottom end of the second rotating shaft extends to the outside of the component frame.

[0006] Preferably, a second motor is installed on one side of the surface of the mounting plate. One end of the second motor passes through the mounting plate and is provided with a first gear. The first gear meshes with a rack, and the second motor is configured to drive the first gear to rotate.

[0007] Preferably, a support plate is provided on one side of the surface of the placement frame, and a vertical plate is provided at the end of the support plate away from the placement frame. The vertical plate is provided to facilitate the placement of the sludge collection box and the sludge pump.

[0008] Preferably, a sludge collection box is provided on the outer wall at the lower end of the upright plate, and a sludge pump is installed on the inner wall at the lower end of the upright plate. The sludge pump is used to pump sludge, weeds and other garbage in the water channel into the sludge collection box.

[0009] Preferably, one end of the sludge pump is equipped with a suction nozzle through a conduit, and the other end of the sludge pump is connected to the surface of the sludge collection box through a flexible hose. The suction nozzle is designed to work in conjunction with the sludge pump to perform suction operations on the sludge in the water channel.

[0010] Preferably, both the first and second rotating shafts are provided with a linkage rod at their bottom ends, and a cutter is installed at the bottom end of the linkage rod. The cutter is used to cut and crush silt, weeds, and domestic waste in the water channel into small particles.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the dredging device for the water conservancy canal not only ensures the dredging effect of the dredging device on the canal when it is used, but also enables dredging operations in designated locations and depths of the canal, thereby expanding the application range of the dredging device and improving the convenience of using the dredging device.

[0012] (1) By moving the cutter to the bottom of the ditch, when the first motor drives the first shaft to rotate, the first shaft will drive the third gear to rotate via the second gear, so that the third gear drives the second shaft to rotate via the belt drive mechanism, thereby causing the first shaft and the second shaft to rotate via the linkage rod to drive the two cutters to rotate, so that the cutters can cut and crush the garbage at the bottom of the ditch, so that the garbage, weeds and other garbage are cut into small particles, making it easier to pump and remove the garbage at the bottom of the ditch into the sludge collection box, thus ensuring the sludge removal effect of the dredging device on the ditch when it is used;

[0013] (2) The top seat is raised and lowered by the lifting drive component, so the height of the cutter and the suction nozzle can be adjusted as needed. Then the first gear is rotated by the second motor. Because the first gear and the rack mesh with each other, the plate slides on the surface of the guide rail via the rail seat, so the lateral position of the cutter and the suction nozzle can be adjusted as needed. This enables dredging operations at designated locations and depths in the water channel, thereby improving the application range of the dredging device.

[0014] (3) The garbage at the bottom of the canal is cut and crushed by the cutting blade, and then the small particles of garbage are pumped into the sludge collection box by the sludge pump through the suction nozzle. At this time, the garbage is stored in the sludge collection box, and the sewage is discharged through the drain mesh on the surface of the sludge collection box. This achieves the purpose of automatically cleaning the canal and collecting garbage, thereby improving the convenience of using the sludge cleaning device. Attached Figure Description

[0022] In use, the second motor 18 is configured to drive the first gear 19 to rotate;

[0023] The surface of the placement plate 8 is provided with a placement frame 16 via a bracket. A support plate 11 is provided on one side of the surface of the placement frame 16, and a vertical plate 12 is provided at the end of the support plate 11 away from the placement frame 16.

[0024] In use, the vertical plate 12 is used to house the sludge collection box 15 and the sludge pump 13.

[0025] A sludge collection box 15 is provided on the outer wall at the lower end of the vertical plate 12, and a sludge pump 13 is installed on the inner wall at the lower end of the vertical plate 12.

[0026] When in use, the sludge pump 13 is set up to pump sludge, weeds and other garbage in the water channel into the sludge collection box 15;

[0027] One end of the sludge pump 13 is equipped with a suction nozzle 14 through a conduit, and the other end of the sludge pump 13 is connected to the surface of the sludge collection box 15 through a hose.

[0028] When in use, the suction nozzle 14 is designed to work with the sludge pump 13 to perform suction operations on the sludge in the water channel.

[0029] A first motor 17 is mounted on the inner wall of the upper end of the frame 16 via a bracket. The bottom end of the first motor 17 is provided with a first rotating shaft 21.

Finally, by moving the cutter 10 down to the bottom of the ditch, when the first motor 17 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 will drive the third gear 24 to rotate via the second gear 22. The third gear 24 will then drive the second rotating shaft 25 to rotate via the belt drive mechanism 23. This will cause the first rotating shaft 21 and the second rotating shaft 25 to drive the two cutter 10 to rotate via the linkage rod 9. The cutter 10 will cut and crush the waste at the bottom of the ditch, breaking the waste, weeds, and other debris into small particles, making it easier to pump and remove the waste from the bottom of the ditch into the sludge collection box 15. This will efficiently clean the ditch and complete the use of the sludge cleaning device.
