Description

Technical Field

[0001] This invention relates to dredging equipment technology, and more particularly to a mobile and convenient dredging device for water conservancy projects. Background Technology

[0002] In water conservancy project maintenance, dredging is a crucial step in ensuring the normal operation of water conservancy facilities. Existing dredging devices often suffer from insufficient structural coordination. Specifically, the power to transport the broken sludge to the filtration chamber is insufficient, easily leading to sludge accumulation and blockage. Furthermore, the conveying and screening mechanisms of traditional dredging devices are independent, requiring separate drive components, resulting in a complex overall structure and increased energy consumption. In addition, the fixed screening structure in some dredging devices cannot be linked with the conveying process, allowing larger impurities to easily enter the filtration chamber with the sludge, increasing the filtration load on subsequent filter plates, shortening their lifespan, and increasing equipment maintenance frequency. In actual operation, these problems limit dredging efficiency, making them unsuitable for complex water conservancy dredging scenarios and failing to meet the demands for efficient and stable dredging operations. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a dredging device with high sludge transport efficiency and anti-clogging capability. By optimizing the transmission linkage structure, it solves the problems of insufficient transport power and local sludge accumulation and blockage caused by traditional dredging devices relying on the sludge's own gravity or a single pushing structure, thereby achieving continuous and stable sludge transport and ensuring the continuity of dredging operations.

[0004] Another objective of this invention is to provide a dredging device with a simplified structure, low energy consumption, and a continuous dredging process, thereby reducing structural complexity and maintenance costs. It also integrates sludge transportation and preliminary screening into one unit, reducing the pressure on subsequent filtration mechanisms, extending the service life of vulnerable parts, and improving the overall efficiency of dredging operations.

[0005] Technical solution: A mobile and convenient dredging device for water conservancy projects, including a base, with drive wheels symmetrically fixedly connected to the outer side wall of the base, and a track wound around the outer side wall of adjacent drive wheels, a filter chamber fixedly connected to the upper surface of the base, a dredging chamber fixedly connected to the rear surface of the filter chamber, and support rods symmetrically fixedly connected to the outer side wall of the filter chamber.

[0006] Furthermore, the outer wall of the support rod is rotatably connected to a rotating rod via a servo motor. Each end of the rotating rod is fixedly connected to a motor, the output end of which extends to the lower surface of the rotating rod and is fixedly connected to a rotating column. The outer wall of the rotating column is fixedly connected to a crushing blade.

[0007] Furthermore, the sludge-clearing chamber has a rotating groove inside, a second motor is fixedly connected inside the rotating groove, a turntable is fixedly connected to the output end of the second motor, a hollow ring is rotatably connected to the lower surface of the turntable, and a cam is fixedly connected to the outer wall of the hollow ring.

[0008] Furthermore, the inner wall of the rotating groove is provided with multiple sliding openings, and each of the multiple sliding openings is slidably connected to a sliding column. The end of each sliding column is fixedly connected to a sliding plate inside the rotating groove. The sliding plate is slidably connected to the inner wall of the rotating groove. The end of each sliding column is fixedly connected to a vertical plate outside the filter chamber. The bottom end of each vertical plate is fixedly connected to a horizontal plate. The outer wall of each sliding column is wound with a spring on the outer wall of the rotating groove.

[0009] Furthermore, the lower surface of the sludge removal chamber is provided with a rotating opening, and a rotating cylinder is rotatably connected inside the rotating opening. The outer side wall of the rotating cylinder is fixedly connected to a sludge extraction chamber, and the inner side wall of the sludge extraction chamber is symmetrically provided with screening holes. An external gear is fixedly connected to the outer side wall of the rotating cylinder, and a rack is fixedly connected to the outer side wall of the horizontal plate. The rack meshes with the external gear.

[0010] Furthermore, a filter plate is fitted inside the filter chamber, and a water pump is fixedly connected to the left side of the filter chamber. The output port of the water pump is fixedly connected to a drain pipe, which extends to the outside of the filter chamber.

[0011] Furthermore, a top cover is snapped onto the upper part of the filter chamber, and limit strips are symmetrically fixedly connected inside the filter chamber. Sliding grooves are symmetrically fixedly connected to the outer side wall of the filter plate, and the outer side wall of the limit strip is slidably connected to the sliding groove.

[0012] Beneficial Effects: The newly added components in the sludge removal chamber, through the linkage design of motor two, cam, slide column, and suction chamber, effectively improve sludge conveying efficiency and prevent sludge accumulation and blockage. Motor two drives the turntable to rotate the cam, which in turn squeezes the slide plate to push the slide column back and forth. This, in turn, drives the rack through the vertical and horizontal plates. The rack meshes with the external gear to drive the rotating drum, causing the suction chamber to rotate synchronously with the drum, generating negative pressure suction. This linkage structure makes the suction of the suction chamber and the sludge pushing process work together, actively extracting the sludge mixture in the sludge removal chamber, solving the problem of insufficient conveying power caused by traditional devices relying on the sludge's own gravity or a single pushing structure. At the same time, the rotation of the suction chamber makes the suction coverage wider, which can thoroughly clean the sludge in the sludge removal chamber, avoid local accumulation and blockage, and ensure that the sludge can be continuously and stably transported to the filtration chamber, ensuring the continuity of sludge removal operations.

[0013] The newly added component uses a single motor as the core drive source, achieving synchronous operation of conveying and screening through mechanical transmission. This simplifies the device structure and reduces energy consumption. The elimination of separate drive components for the conveying and screening mechanisms reduces the number of parts, lowers structural complexity, and facilitates installation, maintenance, and repair. Simultaneously, the screening holes on the inner wall of the sludge suction chamber form a linked screening structure with the rotating chamber. The sludge mixture must pass through these screening holes before entering the rotating drum during extraction. These holes preliminarily intercept larger impurities in the sludge, preventing them from entering the filtration chamber, reducing the filtration pressure on subsequent filter plates, extending their lifespan, and lowering maintenance costs. This integrated design of conveying and preliminary screening simplifies the structure while improving the continuity of the dredging process, further optimizing the overall efficiency of the dredging operation.

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-7As shown, a mobile and convenient dredging device for water conservancy projects is provided, including a base 1. Drive wheels 2 are symmetrically fixedly connected to the outer walls of the base 1. A track 3 is wound around the outer walls of adjacent drive wheels 2. A filter chamber 4 is fixedly connected to the upper surface of the base 1. A dredging chamber 5 is fixedly connected to the rear surface of the filter chamber 4. Support rods 6 are symmetrically fixedly connected to the outer walls of the filter chamber 4. Rotating rods 7 are rotatably connected to the outer walls of the support rods 6 via servo motors. Motors 8 are fixedly connected to the ends of the rotating rods 7, and the output ends of the motors 8 extend to the lower surface of the rotating rods 7. The filter chamber 4 is fixedly connected to a rotating column 9, and a crushing blade 10 is fixedly connected to the outer wall of the rotating column 9. A filter plate 27 is snapped into the filter chamber 4. A water pump 28 is fixedly connected to the left side of the filter chamber 4. A drain pipe 29 is fixedly connected to the output port of the water pump 28. The drain pipe 29 extends to the outside of the filter chamber 4. A top cover 32 is snapped into the top of the filter chamber 4. Limiting strips 30 are symmetrically fixedly connected to the inside of the filter chamber 4. A sliding groove 31 is symmetrically fixedly connected to the outer wall of the filter plate 27. The outer wall of the limiting strip 30 is slidably connected to the sliding groove 31. Before operation, the mobile and convenient dredging device for water conservancy projects must be inspected to ensure that the top cover 32 is securely engaged and that the filter plate 27 is precisely installed through the sliding groove 31 and the limiting strip 30. Simultaneously, the connections of components such as the water pump 28, motor, and servo motor must be checked to ensure they are normal. Then, the mobile system is activated, and the transmission wheel 2 on the base 1 drives the track 3 to rotate, allowing the device to move flexibly to the designated dredging location. Next, the angle of the rotating rod 7 on the support rod 6 is adjusted by the servo motor, aligning the rotating column 9 driven by motor 8 and the crushing blades 10 with the silt area. After starting motor 8, the crushing blades 10 rotate at high speed, breaking large pieces of silt into fine particles. The angle is then finely adjusted by the servo motor, and the thrust of the rotating blades pushes the silt mixture into the dredging chamber 5, and then through the connecting structure into the filter chamber 4. The silt mixture entering the filter chamber 4 undergoes a brief buffer for initial sedimentation, then permeates through the filter plate 27 to complete solid-liquid separation. Solid silt is intercepted above the filter plate, while clean water enters the left side of the chamber. Then, the water pump 28 is started to draw the filtered clean water through the drain pipe 29 and discharge it to the designated area. When it is observed that the water pump discharge volume decreases and the filtration efficiency drops, all components are stopped, the top cover 32 is opened, the filter plate is removed using the sliding structure of the filter plate and the limiting strip, the intercepted silt is cleaned, and the device is reset to complete one round of sludge removal.

[0018] In this embodiment, a rotating groove 11 is provided inside the sludge removal chamber 5. A second motor 12 is fixedly connected inside the rotating groove 11. A turntable 13 is fixedly connected to the output end of the second motor 12. A hollow ring 14 is rotatably connected to the lower surface of the turntable 13. A cam 15 is fixedly connected to the outer wall of the hollow ring 14. Multiple sliding openings 16 are provided on the inner wall of the rotating groove 11. A sliding column 17 is slidably connected inside each of the multiple sliding openings 16. A sliding plate 18 is fixedly connected to the end of the sliding column 17 inside the rotating groove 11. The sliding plate 18 is slidably connected to the inner wall of the rotating groove 11. The end of the sliding column 17 is located inside the rotating groove 11. Vertical plates 19 are fixedly connected to the outside of the filter chamber 4. A horizontal plate 20 is fixedly connected to the bottom of the vertical plates 19. Springs 21 are wound around the outer walls of the sliding column 17 and the outer walls of the rotating groove 11. A rotating opening 22 is opened on the lower surface of the sludge removal chamber 5. A rotating cylinder 23 is rotatably connected inside the rotating opening 22. A sludge suction chamber 24 is fixedly connected to the outer wall of the rotating cylinder 23. Screening holes 25 are symmetrically opened on the inner wall of the sludge suction chamber 24. An external gear 35 is fixedly connected to the outer wall of the rotating cylinder 23. A rack 26 is fixedly connected to the outer wall of the horizontal plate 20. The rack 26 meshes with the external gear 35. After the crushed sludge mixture is pushed into the sludge removal chamber 5, the newly added components immediately start working in tandem to enhance the sludge conveying and preliminary screening effects. First, the motor 12 fixed in the rotating groove 11 of the sludge removal chamber 5 starts, driving the turntable 13 connected to the output end to rotate. The hollow ring 14 rotatably connected to the lower surface of the turntable 13 and the cam 15 fixed to the outer wall rotate synchronously. As the cam 15 rotates, its protruding part continuously squeezes the slide plate 18 in the rotating groove 11, pushing the slide plate 18 to slide along the inner wall of the rotating groove, thereby driving the multiple sliding columns 17 connected to the slide plate to slide back and forth along the sliding opening 16. The spring 21 wrapped around the outside of the sliding column 17 repeatedly extends and retracts with the sliding column, playing a buffering and reset role to ensure sliding stability. The vertical plate 19 and horizontal plate 20 connected to the end of the sliding column 17 extending to the outside of the filter chamber 4 move back and forth synchronously. The rack 26 fixed to the outer wall of the horizontal plate drives the meshing external gear 35 to rotate, thereby driving the rotating drum 23 rotatably connected in the rotating opening 22 to rotate. The sludge suction chamber 24, which is fixedly connected to the outer wall of the rotating drum, rotates with the drum, generating negative pressure suction to accelerate the extraction of the sludge mixture in the sludge suction chamber. When the mixture passes through the screening holes 25 on the inner wall of the sludge suction chamber 24, larger impurities are initially intercepted. The screened sludge is then continuously transported to the filter chamber 4 as the drum rotates, preparing for subsequent solid-liquid separation. The sludge suction continues until the sludge suction operation is completed, at which point the motor 12 stops and all components are reset.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
