Description

River dredging equipment and methods Technical Field

[0001] This invention relates to the field of river dredging technology. More specifically, this invention relates to a river dredging device and method. Background Technology

[0002] Over time, silt easily accumulates at the bottom of river channels in water conservancy projects. This silt can affect the normal functioning of various river functions, such as flood control, drainage, irrigation, water supply, and navigation, thus impacting the normal operation of the water conservancy project. Therefore, regular dredging of the river channels is necessary. Existing technologies typically involve sealing off both ends of the river channel and then using a dredging vessel to remove the silt deposited at the bottom. The dredging vessel is equipped with a dredging machine and a power unit. The dredging machine, driven by the power unit, removes and pumps the silt from the bottom of the river, and then the removed silt is loaded onto the hull or transported by a transport ship. Chinese Patent CN116591252B discloses a dredging device for river channel management in water conservancy projects, which includes a pump and a diversion pipe to pump silt. An alarm is installed inside the diversion pipe to remind workers to adjust the position of the diversion pipe in a timely manner. However, when using the above-mentioned device, due to the limited suction range of the guide pipe, after the silt around the water inlet pipe is cleaned, the position of the pipe needs to be constantly adjusted, which increases the workload. Therefore, the above-mentioned device still has room for improvement. Summary of the Invention

[0003] This invention provides a river dredging device and method, which can expand the suction range of the suction pipe and improve work efficiency.

[0004] To achieve these objectives and other advantages according to the present invention, a river dredging device is provided, comprising a walking mechanism, a robotic arm, and a dredging mechanism. The base of the robotic arm is rotatably mounted on the top of the walking mechanism. The dredging mechanism is connected to the working end of the robotic arm. A collection box is also mounted on the top of the walking mechanism, and a suction pump is disposed within the collection box.

[0005] The dredging mechanism is equipped with a rotating screw and two suction pipes symmetrically arranged on both sides of the rotating screw. One end of the rotating screw is rotatably inserted into a connecting box through a sealed bearing, and the other end is rotatably connected to a fixed plate. A motor is installed in the connecting box, and the rotating screw is coaxially fixed to the rotating shaft of the motor. The working end of the robotic arm is fixedly connected to the top of the connecting box. Both sides of the fixed plate are provided with through holes. One end of each of the two suction pipes is fixedly connected to the two through holes, and the other end of each is connected to the collection box through a hose. A connecting rod is fixedly connected between the two suction pipes, so that the two suction pipes and the connecting rod form a triangular structure. The rotating screw moves vertically through the connecting rod. A first push plate is rotatably fitted around the outer periphery of the rotating screw. Two second push plates are symmetrically movably fitted on the two suction pipes. Both sides of the first push plate are provided with outwardly extending insert plates. The two second push plates have grooves for the insert plates to slide through. The extension direction of the two insert plates and the two grooves is consistent with that of the connecting rod.

[0006] Preferably, the first push plate and the two second push plates are both isosceles trapezoidal structures. The upper base of the two second push plates is flush with the lower base of the first push plate, and the lower base of the two second push plates is flush with the upper base of the first push plate. A threaded hole is vertically connected between the upper and lower bases of the first push plate, and the rotating screw rotates through the threaded hole. The lower base of each of the two second push plates is provided with an outwardly extending extension plate, and an opening is obliquely connected between the parallel upper and lower bases of each second push plate for the corresponding suction tube to move through.

[0007] Preferably, the two insert plates are respectively disposed on the two waist surfaces of the first push plate, and the groove passes through the two waist surfaces of the corresponding second push plate.

[0008] Preferably, the threaded hole and the opening are located near the bottom of the first push plate and the second push plate, respectively.

[0009] Preferably, the two insert plates are close to the top of the first push plate, and the height of the insert plates is less than the height of the first push plate; the two slides are close to the top of the corresponding second push plates, and the height of the slides is greater than the height of the insert plates and less than the height of the second push plates.

[0010] Preferably, the suction tube is made of a rigid material.

[0011] The present invention also provides a dredging method based on the above-mentioned river dredging equipment, comprising the following steps:

[0012] Step 1: The dredging mechanism is placed in the river silt by the control of the robotic arm, and the suction pump is turned on. The silt near the pipe opening is sucked into the collection box by the suction pipe.

[0013] Step 2: Drive the rotating screw to rotate in the forward direction by the motor, so that the first push plate moves along the rotating screw towards the fixed plate. At the same time, under the pushing action of the insert plate and the limiting action of the suction tube, the two second push plates and the first push plate move synchronously towards the fixed plate, thereby pushing the sludge towards the opening of the suction tube and then sucking it into the collection box.

[0014] Step 3: After completing the dredging here, turn off the suction pump and drive the rotating screw to rotate in the opposite direction via the motor. This will cause the first push plate to move the two second push plates toward the connecting box. The walking mechanism will then drive the dredging mechanism to move. Repeat steps 1 and 2 above.

[0015] The present invention has at least the following beneficial effects: The river dredging equipment and method of the present invention utilize the rotation of the rotating screw to drive the first push plate to move, and at the same time drive the two second push plates to move, thereby pushing the silt in the surrounding area to the inlet of the suction pipe, increasing the dredging range and effectively improving work efficiency.

[0026] As shown in Figures 1-6, the present invention provides a river dredging device and method, including a walking mechanism 100, a robotic arm 200, and a dredging mechanism. The base 201 of the robotic arm 200 is rotatably mounted on the top of the walking mechanism 100. The dredging mechanism is connected to the working end of the robotic arm 200. A collection box 101 is also installed on the top of the walking mechanism 100, and a suction pump is installed inside the collection box 101.

[0027] The dredging mechanism includes 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 rotatably inserted into a connecting box 302 via a sealed bearing, and the other end is rotatably connected to a fixed plate 303. A motor 304 is installed inside the connecting box 302, and the rotating screw 300 is coaxially fixed to the rotating shaft of the motor 304. The working end of the robotic arm 200 is fixedly connected to the top of the connecting box 302. Both sides of the fixed plate 303 are provided with through holes 305. One end of each suction pipe 301 is fixedly connected to one of the two through holes 305, and the other end is connected to the collection box 1 via a flexible hose 306. The two suction tubes 301 are connected, and a connecting rod 307 is fixedly connected between them, so that the two suction tubes 301 and the connecting rod 307 form a triangular structure. The rotating screw 300 moves vertically through the connecting rod 307. A first push plate 308 is fitted around the outer periphery of the rotating screw 300. Two second push plates 309 are symmetrically fitted on the two suction tubes 301. Both sides of the first push plate 308 are provided with outwardly extending insert plates 310. The two second push plates 309 are provided with sliding grooves 311 for the insert plates 310 to slide through. The extension direction of the two insert plates 310, the two sliding grooves 311 and 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 hull. A collection box 101 and a base 201 of a robotic arm 200 are mounted on the top of the walking mechanism 100. The base 201 is rotatably connected to the walking mechanism 100. The robotic arm 200 has two hydraulic arm sections. The working ends of the hydraulic arms are connected to the connecting box 302. An electromechanical structure, such as a motor 304, is installed inside the connecting box 302. A rotating screw 300 is coaxially fixed to the shaft of the motor 304. The end of the rotating screw 300 rotatably passes through the side wall of the connecting box 302 via a sealed bearing and is rotatably connected to a fixing plate 303. Two suction pipes 301 are arranged opposite each other on both sides of the rotating screw 300. One end of each suction pipe 301 is fixed... The first end of the suction pipe 300 passes through the fixed plate 303, and the other end is connected to the collection box 101 via the hose 306. A connecting rod 307 connects the two suction pipes 301. The two suction pipes 301 and the connecting rod 307 form an isosceles triangle structure. The rotating bolt moves vertically through the middle of the connecting rod 307, so that the axis of the rotating screw 300 coincides with the center line of the isosceles triangle. A first push plate 308 is rotatably sleeved on the rotating screw 300, and a second push plate 309 is slidably sleeved on the two suction pipes 301. Two insert plates 310 parallel to the connecting rod 307 extend from both sides of the first push plate 308. The two second push plates 309 have grooves 311 for sliding insertion of the corresponding insert 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 hose 306 and suction pipes 301 via a suction pump. In use, the suction pump is turned on, and the sludge is sucked up using the suction pipe 301. Turning on the motor 304 drives the rotating screw 300 to rotate, thereby moving the first push plate 308 forward. The two second push plates 309, pushed by the insert plate 310 and limited by the suction pipe 301, move forward with the first push plate 308, thus pushing the sludge towards the opening of the suction pipe 301. This technical solution utilizes the robotic arm 200 to drive the sludge removal mechanism, improving flexibility; the two suction pipes 301 and the connecting rod 307 form a triangular structure, improving structural stability; while the two suction pipes 301 suck up sludge, they also allow the second push plates 309 to slide and be limited, combined with the driving action of the first push plate 308, simplifying the drive structure and saving energy; the two second push plates 309 move from being far apart to being close to the first push plate 308, gradually pushing a large area of ​​sludge towards the opening of the suction pipe 301, expanding the sludge removal 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 both isosceles trapezoidal structures. The upper bottom surface of the two second push plates 309 is flush with the lower bottom surface of the first push plate 308, and the lower bottom surface of the two second push plates 309 is 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. The rotating screw 300 rotates through the threaded hole 312. The lower bottom surface of each of the two second push plates 309 is provided with an outwardly extending extension plate 313. An opening 314 is obliquely provided between the 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, when the first pushing plate 308 and the two second pushing plates 309 approach and abut against each other, they can form a complete trapezoidal structure, which facilitates the pushing of silt. The extension plate 313 is provided to expand the pushing range of silt and improve work efficiency.

[0030] In another technical solution, two insert plates 310 are respectively disposed on two waist surfaces of the first push plate 308, and the sliding groove 311 passes 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, thereby improving the smoothness of the structural movement.

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

[0032] In another technical solution, two insert plates 310 are located near the top of the first push plate 308, and the height of the insert plates 310 is less than the height of the first push plate 308. Two sliding grooves 311 are located near the top of their respective second push plates 309, and the height of the sliding grooves 311 is greater than the height of the insert plates 310 but less than the height of the second push plate 309. In this technical solution, the opening 314 is located near the bottom of the push plate, and the insert plates 310 and sliding grooves 311 are located near the top of the push plate, so that the opening 314 and the 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 rigid material. In this technical solution, the suction pipe 301 has a rigid structure, which improves structural stability. Spiral blades or similar components can also be installed inside the suction pipe 301 to improve the suction effect on silt.

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

[0035] Step 1: The dredging mechanism is placed in the river silt by the control of the robotic arm 200, the suction pump is turned on, and the silt near the pipe opening is sucked into the collection box 101 by the suction pipe 301.

[0036] Step 2: The motor 304 drives the rotating screw 300 to rotate in the forward direction, causing the first push plate 308 to move along the rotating screw 300 towards 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 towards the fixed plate 303, thereby pushing the sludge towards the opening of the suction pipe 301 and then sucking it 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 towards the connecting box 302, and use the walking mechanism 100 to drive the dredging mechanism to move, repeating the above steps 1 and 2.

[0038] In the above technical solution, the position of the dredging mechanism is adjusted by 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 the suction pump and suction pipe 301, which facilitates 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 area around the suction pipe 301 toward the opening of the suction pipe 301, which facilitates the suction pipe 301 to suck the sludge, expands the working range, and improves the working efficiency.

[0039] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0040] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
