Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering equipment, and in particular relates to a dredging device for water conservancy engineering. Background Technology

[0002] In water conservancy projects, after long-term use, the inner walls of water conveyance facilities such as pipelines and channels are prone to accumulating silt, debris, biological residues and other sediments. If not cleaned in time, it will lead to a reduction in the water conveyance cross-section and an increase in water flow resistance. This will not only reduce water conveyance efficiency, but may also cause pipeline blockage, corrosion and aging, and even affect the structural safety of water conservancy facilities. Therefore, dredging devices are key equipment for the maintenance of water conservancy projects.

[0003] A Chinese patent application with publication number CN216225939U discloses a dredging device for water conservancy projects, including a hollow cylinder. A circular through hole is opened at the center of the front surface of the hollow cylinder, and a groove opening is opened on the inner side of the circular through hole. The hollow cylinder has a pull-out structure inside. This utility model can quickly dredge pipes blocked by silt and garbage by using the pull-out structure in conjunction with a rubber piston. The operation process is convenient and simple.

[0004] Although this patent can quickly unclog pipes, it still suffers from low cleaning efficiency and lacks autonomous movement capability. It requires external force such as manual dragging, winch traction, or boat towing to move within the pipe or channel. On the one hand, manual dragging is labor-intensive and affected by the operator's physical strength and skill level, resulting in slow dredging speed and making it unsuitable for dredging operations on long-distance, large-diameter pipes. On the other hand, external traction equipment often requires additional auxiliary facilities, has a complex operation process, and is prone to problems such as device jamming and movement trajectory deviation during traction, leading to incomplete dredging and residual silt in some areas, further reducing dredging efficiency.

[0005] Therefore, we provide a dredging device for water conservancy projects to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dredging device for water conservancy projects. By combining the side support component and the dredging component, it solves the problem that existing dredging devices for water conservancy projects lack autonomous movement capabilities and need to rely on external forces such as manual dragging, winch traction, or boat towing to move within pipelines or channels, resulting in low dredging efficiency.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a dredging device for water conservancy projects, comprising a housing, with side support assemblies fixedly connected to both sides of the housing, and a dredging assembly disposed at the bottom of the housing. Each side support assembly includes a fixing screw, one end of which is movably connected to the surface of the housing. An adjusting threaded tube is threadedly connected to the surface of the fixing screw, and a fixing frame is movably connected to one end of the adjusting threaded tube. A reduction motor is disposed at the top of the fixing frame, and a side wheel is movably connected to the inner cavity of the fixing frame. The output shaft of the reduction motor is fixedly connected to one end of the side wheel. The dredging assembly includes a drive motor, which is fixedly connected to the inner cavity of the housing. A rotating arm is fixedly connected to the output shaft of the drive motor. A spring is fixedly connected to the bottom of the inner cavity of the rotating arm, and a telescopic member is fixedly connected to the top of the spring. A scraper is fixedly connected to the top of the telescopic member via a support rod.

[0009] The present invention is further configured such that a support assembly is provided at the bottom of the outer shell, the support assembly including a support screw, the top of the support screw being movably connected to the bottom of the outer shell, a support threaded tube being threadedly connected to the surface of the support screw, a support frame being fixedly connected to the bottom of the support threaded tube, and a support wheel being provided in the inner cavity of the support frame. When the sludge removal device is placed in the pipe, with the support wheel located at the bottom of the inner cavity of the pipe, the support screw is rotated. When the support screw rotates, it will drive the support threaded tube to move downward, and the support threaded tube will drive the support wheel to move downward, thereby enabling the scraper on the sludge removal device to contact the inner wall of the pipe, so that the sludge removal device can move stably in the pipe to perform sludge removal work.

[0010] The present invention is further configured such that movable plates are movably connected to both sides of the top of the support frame, and the end of the movable plate away from the support frame is movably connected to the bottom of the outer shell. The two movable plates swing as the support frame moves up and down, and the stability of the support frame when moving up and down can be improved by the limiting effect of the movable plates.

[0011] The present invention is further configured such that an adjusting wheel is fixedly connected to the surface of the supporting screw, and an anti-slip rod is provided on the surface of the adjusting wheel. The anti-slip rods on the surface of the adjusting wheel can greatly increase the friction of the adjusting wheel surface, making it convenient for the operator to rotate the adjusting wheel by hand.

[0012] The present invention is further configured such that a water spray frame is fixedly connected to one side of the outer shell, and a water receiving pipe is provided on one side of the water spray frame. One end of an external water supply hose is connected to the water receiving pipe, and water is injected into the inner cavity of the water spray frame through the water receiving pipe. Under pressure, the water is sprayed at high speed through the water spray holes on the surface of the water spray frame to the inner wall of the pipe, thereby cleaning the inner wall of the pipe.

[0013] The present invention is further configured such that a fixing frame is fixedly connected to one side of the fixing screw, and a limiting frame is fixedly connected to the bottom of the fixing frame. One side of the limiting frame is movably connected to the surface of the fixing frame through a sliding sleeve. The sliding sleeve on one side of the limiting frame moves on the surface of the fixing frame as the fixing frame moves. The limiting structure composed of the fixing frame and the limiting frame can improve the stability of the fixing frame and its inner cavity side wheels during adjustment.

[0014] The present invention is further configured such that limiting plates are fixedly connected to both sides of the inner cavity of the rotating arm, the bottom of the limiting plate is in contact with the surface of the telescopic member, and the telescopic member will contact the bottom of the limiting plate after the inner cavity of the rotating arm moves to the limit position. The limiting effect of the limiting plate can prevent the telescopic member from moving out of the inner cavity of the rotating arm.

[0015] The present invention is further configured such that scraper blades are fixedly connected to the surface of the scraper, the scraper blades being made of the same material as the scraper, and multiple scraper blades forming a continuous sludge scraping structure on the surface of the scraper, which can efficiently scrape away the sludge on the inner wall of the pipe.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model realizes efficient and automated dredging operations. It drives the side wheels to rotate on the inner wall of the pipe through the built-in geared motor, thereby having the ability to move independently. It completely gets rid of the dependence on external manual dragging or traction equipment. This not only significantly reduces the labor intensity of operators, but also avoids the problem of jamming or trajectory deviation caused by insufficient traction, ensuring that the dredging device can move forward stably and at a constant speed.

[0018] 2. This utility model demonstrates high adaptability and thoroughness in dredging. Both its support wheels and side wheels can be adjusted via screws, allowing the scraper to conform to the inner walls of pipes with different diameters. At the same time, the clamping design of the side wheels enhances the stability of the equipment during movement. Combined with high-pressure water spray to soften the sludge and the scraper rotation driven by spring telescopic components for cleaning, this design can actively adapt to the unevenness of the inner wall of the pipe, achieving a synergistic dredging effect of "softening and scraping," effectively reducing residue. It is particularly suitable for dredging tasks of long-distance, large-diameter pipelines. Attached Figure Description

[0028] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figure 1-7 This utility model is a dredging device for water conservancy projects, including a shell 1. Side support components 2 are fixedly connected to both sides of the shell 1, and a dredging component 3 is provided at the bottom of the shell 1. The side support components 2 include a fixing screw 201, one end of which is movably connected to the surface of the shell 1. An adjusting threaded tube 202 is threadedly connected to the surface of the fixing screw 201. A fixing frame 203 is movably connected to one end of the adjusting threaded tube 202. A reduction motor 204 is provided at the top of the fixing frame 203. A side wheel 205 is movably connected to the inner cavity of the fixing frame 203. The output shaft of the reduction motor 204 is fixedly connected to one end of the side wheel 205. The dredging component 3 includes a drive motor 301, which is fixedly connected to the inner cavity of the shell 1. A rotating arm 302 is fixedly connected to the output shaft of the drive motor 301. A spring 303 is fixedly connected to the bottom of the inner cavity of the rotating arm 302. A telescopic member 304 is fixedly connected to the top of the spring 303. A scraper 305 is fixedly connected to the top of the telescopic member 304 through a support rod.

[0030] Specifically: Rotate the adjusting threaded tube 202. As the adjusting threaded tube 202 rotates, it will move on the surface of the fixed screw 201, thereby driving the fixed frame 203 at one end and the side wheel 205 in its inner cavity to move until the side wheels 205 on both sides of the outer shell 1 are pressed against the inner wall of the pipe to be dredged. When the dredging work starts, turn on the reduction motor 204. The two reduction motors 204 run synchronously to drive the side wheel 205 to rotate. The two side wheels 205 rotate synchronously on the inner wall of the pipe to be dredged, thereby driving the dredging device to move at a constant speed in the pipe to be dredged.

[0031] A support assembly 4 is provided at the bottom of the outer casing 1. The support assembly 4 includes a support screw 401. The top of the support screw 401 is movably connected to the bottom of the outer casing 1. A support threaded tube 402 is threadedly connected to the surface of the support screw 401. A support frame 403 is fixedly connected to the bottom of the support threaded tube 402. A support wheel 404 is provided in the inner cavity of the support frame 403. Movable plates 5 are movably connected to both sides of the top of the support frame 403. The end of the movable plate 5 away from the support frame 403 is movably connected to the bottom of the outer casing 1. The surface of the support screw 401 is fixedly connected to... It has an adjusting wheel with an anti-slip rod on its surface. A water spray frame 6 is fixedly connected to one side of the outer shell 1, and a water inlet pipe 7 is provided on one side of the water spray frame 6. A fixing bracket is fixedly connected to one side of the fixing screw 201. A limit bracket is fixedly connected to the bottom of the fixing frame 203. One side of the limit bracket is movably connected to the surface of the fixing bracket through a sliding sleeve. Limit plates are fixedly connected to both sides of the inner cavity of the rotating arm 302. The bottom of the limit plate is in contact with the surface of the telescopic member 304. A scraper blade is fixedly connected to the surface of the scraper 305. The scraper blade is made of the same material as the scraper blade 305.

[0032] Specifically: The sludge removal device is placed in the pipeline, with the support wheel 404 located at the bottom of the pipeline cavity. Rotating the support screw 401 causes the support threaded tube 402 to move downwards, which in turn moves the support wheel 404 downwards. This allows the scraper 305 on the sludge removal device to contact the inner wall of the pipeline, enabling the device to move stably within the pipeline for sludge removal. The two movable plates 5 swing as the support frame 403 moves up and down. The limiting effect of the movable plates 5 improves the stability of the support frame 403 during its up-and-down movement. Several anti-slip rods on the surface of the adjusting wheel greatly increase the friction, making it easier for workers to manually rotate the adjusting wheel and connect one end of the external water supply hose to the water inlet. Pipe 7 is connected, and water is injected into the inner cavity of the spray frame 6 through the water inlet pipe 7. Under pressure, the water is sprayed at high speed through the spray holes on the surface of the spray frame 6 to clean the inner wall of the pipe. The sliding sleeve on one side of the limiting frame moves on the surface of the fixed frame as the fixed frame 203 moves. The limiting structure composed of the fixed frame and the limiting frame can improve the stability of the fixed frame 203 and its inner cavity side wheel 205 during adjustment. After the telescopic part 304 moves to the limit position in the inner cavity of the rotating arm 302, it will contact the bottom of the limiting plate. The limiting effect of the limiting plate can prevent the telescopic part 304 from moving out of the inner cavity of the rotating arm 302. Multiple scrapers form a continuous sludge scraping structure on the surface of the scraper 305, which can efficiently scrape off the sludge on the inner wall of the pipe.

[0033] The working principle of this utility model is as follows: The dredging device is placed in the pipe to be dredged, with the support wheel 404 positioned at the bottom of the pipe cavity. The support screw 401 is rotated, causing the support threaded tube 402 to move downwards. The support threaded tube 402 then moves the support wheel 404 downwards, thereby causing the scraper 305 on the dredging device to move upwards and contact the inner wall of the pipe. One end of the external water supply hose is connected to the water inlet pipe 7. The adjusting threaded tube 202 is rotated, causing it to move on the surface of the fixed screw 201, which in turn moves the fixed frame 203 at one end and the side wheels 205 within its cavity until the side wheels 205 on both sides of the outer casing 1 are pressed tightly against the inner wall of the pipe to be dredged. When the dredging operation begins, the reduction motor 204 is turned on. Two geared motors 204 operate synchronously, driving the side wheels 205 to rotate. The two side wheels 205 rotate synchronously on the inner wall of the pipe to be cleaned, thereby driving the cleaning device to move at a constant speed in the pipe. Then, water is injected into the inner cavity of the spray frame 6 through the water inlet pipe 7. Under pressure, the water is sprayed at high speed through the spray holes on the surface of the spray frame 6 onto the inner wall of the pipe. The drive motor 301 is turned on, and the output shaft of the drive motor 301 drives the rotating arm 302 to rotate. The rotating arm 302 drives the telescopic member 304 at one end and the scraper 305 at the other end to rotate, scraping the sludge on the inner wall of the pipe. The telescopic member 304 is set in the inner cavity of the rotating arm 302 by the spring 303. When squeezed, it can retract into the inner cavity of the rotating arm 302, which can adapt to different conditions of the inner wall of the pipe.
