[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0026] The utility model can break up and dredge the silt accumulated in the pipeline by arranging a hydraulic cylinder 2, a drill bit 6 and a spiral blade 4, and provide thrust through the hydraulic cylinder 2 during the dredging process, thereby realizing uninterrupted dredging and greatly improving the dredging efficiency. Thoroughly removing the silt in the pipeline can significantly improve the drainage efficiency, ensure unobstructed water flow, and reduce the risk of urban waterlogging. In addition, by disassembling and assembling components, the staff can respond quickly when the hydraulic cylinder 2 fails or requires maintenance, effectively shortening the downtime, thereby improving the overall work efficiency, greatly simplifying the maintenance process, and reducing the maintenance cost. At the same time, by replacing spiral blades 4 of different specifications, the device is given excellent flexibility, and can quickly adapt to the cleaning needs of pipelines of different specifications and types, thereby greatly improving the utilization rate of the equipment and making the municipal pipeline dredging work more efficient and convenient.

[0027] The rotating shaft 3 is a stepped shaft, the shaft section between the spiral blade 4 and the drill bit 6 is a small diameter section, the end of the drill bit fixed to the rotating shaft is the maximum diameter end of the drill bit, and the maximum diameter of the drill bit 6 is larger than the shaft diameter of the small diameter section of the rotating shaft 3. The small diameter section of the rotating shaft 3 can reduce its own weight. In addition, the maximum diameter of the drill bit 6 is larger than the shaft diameter of the small diameter section of the rotating shaft 3, which has the effect of slowing down the impact of silt on the limit cylinder 8 when the hydraulic cylinder 2 is extended.

[0028] The driving assembly includes a housing 1, a motor 23, a transmission mechanism and a fixed shaft 19. The motor 23 is fixedly installed inside the housing 1. The fixed shaft 19 is movably connected to the housing 1 on the side close to the rotating shaft 3. The rotating shaft 3 is fixedly connected to the fixed shaft 19. The motor output shaft and the fixed shaft 19 are driven by the transmission mechanism. The power of the motor 23 is transmitted to the fixed shaft 19 through the transmission mechanism, thereby driving the rotating shaft 3 and the spiral blade to rotate coaxially, thereby cleaning the sludge in the pipeline.

[0029] A support base 24 is arranged at the bottom of the motor 23, and the interior of the support base 24 is U-shaped. The support base 24 provides support for the motor 23 to improve the stability of the motor 23.

[0030] The transmission mechanism is a belt drive, a chain drive or a gear drive. When the transmission mode is a belt drive, the transmission mechanism includes a driving wheel, a driven wheel and a transmission belt, wherein the driving wheel is fixedly connected to the output shaft of the motor, the driven wheel is fixedly connected to the fixed shaft, and the transmission belt is movably connected to the driven wheel and the driving wheel to realize the transmission function between the motor and the fixed shaft.

[0031] The bottom surface of the box is provided with a plurality of universal wheels 25. Preferably, the number of universal wheels is four and the size and shape are the same. By providing the universal wheels 25, the movement of the drive assembly is facilitated, thereby driving the movement of the rotating shaft 3, and facilitating the drill bit 6 to break the silt.

[0032] A plurality of limiting cylinders 8 are circumferentially fixedly connected on the outer circumferential surface of the small diameter section of the rotating shaft 3, and a corresponding spring 9 is fixedly installed in each limiting cylinder 8. A telescopic rod 5 is movably installed in each limiting cylinder 8. The outer edge of the telescopic rod 5 arranged circumferentially at one end in the limiting cylinder 8 cooperates with the inner edge arranged circumferentially on the inner wall of the limiting cylinder near the cleaning brush to achieve the limiting of the telescopic rod 5. The end of the telescopic rod 5 located in the limiting cylinder 8 contacts the spring 9, and the end of the telescopic rod 5 located outside the limiting cylinder 8 is fixedly connected to the cleaning brush 7. The arrangement of the telescopic rod 5 and the spring 9 can meet the cleaning needs of pipelines of different diameters. In addition, the cleaning brush 7 can clean the sludge on the inner wall of the pipeline. Regular cleaning of the inner wall of the pipeline can remove the sludge and impurities that corrode and wear the pipeline, extend the service life of the pipeline, reduce the frequency of replacing the pipeline, and reduce the replacement cost.

A limiting groove 20 is provided on the side wall of the mounting seat 11. The inner wall of the limiting groove 20 has a slope. The mounting plate 11 is slidably connected in the guide groove. A connecting block 15 is fixedly connected to one end of the mounting plate 14 away from the spring 22. A connecting block 16 is fixedly installed on the side of the connecting block 15 close to the spring 22. Each connecting block 16 is fixedly connected to one end close to the spring 22 with a limiting block 18 having the same slope as the limiting groove 20. When the device is in working state, the limiting block (18) is clamped with the limiting groove 1 (20) having the same slope. The connecting block 15 and the connecting block 2 16 provide a gripping space for the staff to disassemble and assemble the hydraulic cylinder 2. The spring 22 can provide a thrust when the limit groove 20 and the limit block 18 are connected to prevent the mounting plate 14 from detaching or sliding out of the mounting seat 11. At the same time, by pushing the mounting plate toward the bottom of the guide groove, the spring 22 is compressed, and the limit block 18 slides out of the limit groove 20, thereby realizing the disassembly of the mounting plate 14.

[0034] At least one spring 22 is provided, and when there are multiple springs 22, they are evenly distributed at the bottom of the guide groove. At least one connecting block 15, connecting block 2 16 and limit block 18 are provided, and when there are only one connecting block 15, connecting block 2 16 and limit block 18, they can be arranged on the mounting plate 14. Preferably, two connecting blocks 15, connecting block 2 16 and limit block 18 are provided, which are symmetrically arranged on the side wall of the mounting plate 14 away from the spring 22, so that the staff can hold them with both hands.

[0035] When the mounting plate 14 is connected to the mounting seat 11, the shape of the second connecting block 16 and the selection of a material with elastic deformation properties enable the stop block 18 to engage with the stop groove 1 20 when the device is in working state.

[0036] The disassembly assembly component also includes a support plate 10, a fixed block 12 and a tool box 13. The mounting seat 11 is fixedly connected to the support plate 10. The fixed block 12 is fixedly installed on the side of the support plate 10 away from the hydraulic cylinder 2. The fixed block 12 is provided with a second limiting groove 21, and the tool box 13 is inserted into the second limiting groove 21. Preferably, the second limiting groove is a T-shaped limiting groove, and the tool box is connected to the second limiting groove by fixing the T-shaped plate. The tool box 13 can be disassembled, assembled and replaced through the second limiting groove 21. In addition, when the staff performs equipment maintenance or adjustment, they can directly take out the required tools and spare parts from the tool box 13, thereby greatly saving time.

[0037] The bottom surface of the support plate is fixedly connected to a plurality of positioning blocks 17. Preferably, the number of positioning blocks is four and they are of the same size and shape. The support plate 10 is fixed by the positioning blocks 17. For example, it can be fixed on the ground or on an equipment vehicle. The fixing of the support plate 10 by the positioning blocks 17 provides support for the operation of the hydraulic cylinder 22 and improves the stability of the hydraulic cylinder 22.

[0038] The hydraulic cylinder is a customized hydraulic cylinder with a maximum allowable stroke of 50 meters, which can meet the needs of most pipeline desilting.

[0039] The utility model is a pipeline desilting device for municipal engineering, and its specific working steps are described as follows:

[0040] Step 1: Place the device inside the pipe to be cleaned, and adjust the distance between the device and the pipe until the drill bit 6 contacts the sludge;

[0041] Step 2: The staff uses steel nails to drive into the multiple positioning blocks 17 to fix the support plate 10 on the ground;

[0042] Step 3: The cleaning brush and the telescopic rod 5 are squeezed by the pipeline, so that the telescopic rod 5 compresses the spring until the cleaning brush fits the inner wall of the pipeline;

[0043] Step 3: Turn on the motor 23 to transmit power to the fixed shaft 19 through the transmission mechanism, thereby driving the rotating shaft 3 to rotate, the spiral blade 4 to rotate synchronously, and the cleaning brush 7 and the drill bit 6 on the rotating shaft 3 to rotate coaxially. The drill bit 6 initially crushes the sludge, the cleaning brush 7 scrubs the inner wall of the pipe, and the spiral blade 4 further crushes the sludge, and the crushed sludge is transported out of the pipe through the spiral blade 4;

[0044] Step 4: Control the piston rod of the hydraulic cylinder 2 to extend, and push the drive assembly into the depth of the pipeline through the universal wheel 25, so as to achieve rapid dredging and thorough desilting of the pipeline;

[0045] Step 5: When the hydraulic cylinder 2 needs to be replaced or maintained, the staff holds the second connection block 16 and pushes the mounting plate 14 toward the second springs 22. During the compression of the second springs 22, the second limit blocks 18 are separated from the corresponding limit grooves 20, thereby realizing the disassembly of the hydraulic cylinder 2.

[0046] Step six, when the hydraulic cylinder 2 is maintained and needs to be installed, the staff holds the connecting block 2 16 and slides the mounting plate 14 into the mounting seat 11 along the guide groove until the multiple limit blocks 18 enter the corresponding limit groove 1 20 to fix the hydraulic cylinder.
