Description

Technical Field

[0001] The present invention relates to the technical field of river channel desilting, and more particularly to a river channel desilting device and method. Background Art

[0002] As time goes by, silt tends to accumulate at the bottom of the river channel of a water conservancy project. The silt at the bottom of the river channel will affect the normal performance of various functions of the river channel, such as flood control, drainage, irrigation, water supply, and navigation, thereby affecting the normal operation of the water conservancy project. Therefore, it is necessary to regularly desilt the river channel of the water conservancy project. In the prior art, the two ends of the river channel are usually blocked first, and then a silt clearing ship is used to clear the silt deposited on the river bottom. The silt clearing ship is equipped with a silt clearer, a power unit, etc. The silt clearer is driven by power to remove and suck out the bottom silt, and then the cleaned silt is loaded on the hull or transported by a transport ship. Chinese patent CN116591252B discloses a silt clearing device for river channel management of a water conservancy project, which is provided with a pump body and a diversion pipe to suck out the silt, and an alarm is provided in the diversion pipe to remind the staff to adjust the position of the diversion pipe in time. However, when the above device is used, due to the limited suction range of the guide pipe, after the sludge around the water inlet pipe is cleaned, the pipe position needs to be constantly adjusted, which increases the workload. Therefore, the above device still needs to be improved. Summary of the Invention

[0027] The dredging mechanism is provided with a rotating screw 300 and two suction pipes 301 symmetrically arranged on both sides of the rotating screw 300. One end of the rotating screw 300 is rotated and penetrated into a connecting box 302 through a sealed bearing, and the other end is rotatably connected to a fixed plate 303. A motor 304 is installed in the connecting box 302. The rotating screw 300 is coaxially fixed to the rotating shaft of the motor 304. The working end of the robotic arm 200 is fixed to the top of the connecting box 302. Through holes 305 are provided on both sides of the fixed plate 303. One end of the two suction pipes 301 is fixedly connected to the two through holes 305 respectively, and the other end is connected to the collection box 1 through a hose 306. 01 is connected, and a connecting rod 307 is fixedly connected between the two suction pipes 301, so that the two suction pipes 301 and the connecting rod 307 are surrounded to form a triangular structure, and the rotating screw 300 moves vertically through the connecting rod 307, and the outer periphery of the rotating screw 300 is matched with a first push plate 308 for rotation, and two second push plates 309 are symmetrically movably sleeved on the two suction pipes 301, and both sides of the first push plate 308 are provided with outwardly extending plug plates 310, and the two second push plates 309 are provided with sliding grooves 311 for the plug plates 310 to slide through, and the two plug plates 310, the two sliding grooves 311 and the extension direction of the connecting rod 307 are all consistent.

[0028] In the above technical solution, the walking mechanism 100 can be a vehicle body or a ship body, and a collection box 101 and a base 201 of a mechanical arm 200 are set on the top of the walking mechanism 100. The base 201 is rotatably connected to the walking mechanism 100, and the mechanical arm 200 is provided with two hydraulic arms. The working ends of the hydraulic arms are connected to the connecting box 302. The connecting box 302 is equipped with electromechanical structures such as a motor 304. The rotating shaft of the motor 304 is coaxially fixed with a rotating screw 300. The end of the rotating screw 300 rotates through the side wall of the connecting box 302 through a sealed bearing and is rotatably connected to the fixed plate 303. Two suction pipes 301 are relatively arranged on both sides of the rotating screw 300, and one end of the two suction pipes 301 is fixed. The two suction pipes 301 are connected to the collection box 101 via a flexible tube 306. A connecting rod 307 is connected between the two suction pipes 301. The two suction pipes 301 and the connecting rod 307 form an isosceles triangle structure. A rotating bolt is rotated vertically through the middle of the connecting rod 307, so that the axis of the rotating screw 300 coincides with the midline of the isosceles triangle. A first push plate 308 is rotatably mounted on the rotating screw 300, and a second push plate 309 is slidably mounted on the two suction pipes 301. Two plug plates 310 extending from either side of the first push plate 308 are parallel to the connecting rod 307. The two second push plates 309 are provided with slots 311 for sliding engagement with the corresponding plug plates 310. The collection box 101 is equipped with a filter screen and has a water outlet and a mud outlet at the bottom. It is connected to the flexible tube 306 and the suction pipe 301 via a suction pump. During use, the suction pump is turned on to suck the sludge through the suction pipe 301. The motor 304 is turned on to drive the screw 300 to rotate, thereby driving the first push plate 308 to move forward. The two second push plates 309, driven by the insert plate 310 and the limiting effect of the suction pipe 301, move forward with the first push plate 308, thereby pushing the sludge toward the mouth of the suction pipe 301. This technical solution uses the robot arm 200 to drive the dredging mechanism, which improves flexibility. The two suction pipes 301 and the connecting rod 307 form a triangular structure, which improves the stability of the structure. The two suction pipes 301 suck the sludge while also allowing the second push plates 309 to slide in a limited position. Combined with the driving effect of the first push plate 308, the drive structure is simplified and energy is saved. The two second push plates 309 gradually move away from each other and closer to the first push plate 308, gradually pushing a large area of ​​sludge to the mouth of the suction pipe 301, expanding the dredging range and improving the working efficiency of the suction pipe 301.

[0029] In another technical solution, the first push plate 308 and the two second push plates 309 are all isosceles trapezoidal structures, the upper bottom surfaces of the two second push plates 309 are flush with the lower bottom surface of the first push plate 308, and the lower bottom surfaces of the two second push plates 309 are flush with the upper bottom surface of the first push plate 308. A threaded hole 312 is vertically provided between the upper bottom surface and the lower bottom surface of the first push plate 308, and the rotating screw 300 rotates through the threaded hole 312. The lower bottom surfaces of the two second push plates 309 are both provided with outwardly extending extension plates 313, and an opening 314 is obliquely provided between the mutually parallel upper bottom surface and the lower bottom surface of each second push plate 309 for the corresponding suction tube 301 to move through. In this technical solution, the first push plate 308 and the two second push plates 309 can form a complete trapezoidal structure when they are close to and abut against each other, which is convenient for pushing the sludge. The extension plate 313 is provided to expand the pushing range of the sludge and improve work efficiency.

[0030] In another technical solution, two insert plates 310 are respectively provided on the two waist surfaces of the first push plate 308, and the slide groove 311 extends through the two waist surfaces of the corresponding second push plate 309. In this technical solution, the two insert plates 310 are parallel to the connecting rod 307 and perpendicular to the rotating screw 300, improving the smoothness of the structural movement.

[0031] In another technical solution, the threaded hole 312 and the opening 314 are respectively close to the bottom of the first push plate 308 and the second push plate 309. In this technical solution, the threaded hole 312 and the opening 314 are arranged close to the bottom of the push plate to facilitate the suction pipe 301 to suck the silt at the bottom of the river channel.

[0032] In another technical solution, two inserting plates 310 are located near the top of the first push plate 308, and the height of each inserting plate 310 is less than that of the first push plate 308. Two sliding grooves 311 are located near the top of the corresponding second push plate 309, and the height of each sliding groove 311 is greater than the height of the inserting plates 310 but less than that of the second push plate 309. In this technical solution, the opening 314 is located near the bottom of the push plate, and the inserting plates 310 and sliding grooves 311 are located near the top of the push plate, so that the opening 314 and sliding grooves 311 do not interfere with each other, ensuring smooth sliding.

[0033] In another technical solution, the suction pipe 301 is made of a hard material. In this technical solution, the suction pipe 301 is a hard structure to improve structural stability. Spiral blades can also be installed in the suction pipe 301 to improve the suction effect of sludge.

[0034] The present invention also provides a dredging method based on the above-mentioned river dredging equipment, comprising the following steps:

[0035] Step 1: Use the robotic arm 200 to control the silt removal mechanism to be placed in the riverbed silt, start the suction pump, and use the suction pipe 301 to suck the silt near the pipe opening into the collection box 101;

[0036] Step 2: The motor 304 drives the rotating screw 300 to rotate forward, causing the first push plate 308 to move along the rotating screw 300 toward the fixed plate 303. At the same time, under the pushing action of the insert plate 310 and the limiting action of the suction pipe 301, the two second push plates 309 and the first push plate 308 move synchronously toward the fixed plate 303, thereby pushing the sludge toward the nozzle of the suction pipe 301 and then being sucked into the collection box 101.

[0037] Step 3: After completing the dredging here, turn off the suction pump, drive the rotating screw 300 to rotate in the opposite direction through the motor 304, so that the first push plate 308 drives the two second push plates 309 to move toward the direction close to the connection box 302, and use the walking mechanism 100 to drive the dredging mechanism to move, and repeat the above steps 1 and 2.

[0038] In the above technical solution, the position of the dredging mechanism is adjusted by using the walking mechanism 100 and the robotic arm 200, making the operation flexible and convenient; the sludge is sucked into the collection box 101 by using the suction pump and the suction pipe 301, which is convenient for transportation or subsequent processing; the motor 304 drives the first push plate 308 together with the second push plate 309 to move, pushing the sludge in a large range around the suction pipe 301 toward the pipe mouth of the suction pipe 301, making it convenient for the suction pipe 301 to suck the sludge, expanding the working range and improving work efficiency.
