Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, and in particular to a pulse-type underground seepage pipe network cleaning device. Background Technology

[0002] Buried permeable pipes are widely used in urban drainage, garden drainage, and tunnel drainage due to their excellent drainage performance and durability. Buried permeable pipes are laid underground, and during periods of heavy rainfall or irrigation, excess water is quickly discharged through them. Over time, sediment can clog the permeable holes or accumulate at the bottom of the pipe. If not cleaned promptly, this reduces drainage efficiency and can eventually lead to complete blockage. To clean these pipes, pipe cleaning devices are typically used, inserting a cleaning head into the drain outlet. However, existing pipe cleaning devices have limited cleaning depth and cannot accommodate longer permeable pipes, resulting in incomplete cleaning. Utility Model Content

One end of the feeding rod is movably disposed between two oppositely disposed driven rollers. One end of the water supply pipe is connected to the pulse cleaning assembly. The pulse cleaning assembly is fixedly mounted on the movable base plate.

[0005] Preferably, the support device includes a support body, and the support body is provided with a plurality of elastic components along the axial direction. The top of each of the plurality of elastic components is fixedly connected to an inner support plate. Two first supports and two second supports are provided between the inner support plate and the support body. One end of each of the two first supports is hinged to the inner support plate, and one end of each of the two second supports is hinged to the support body. The first supports and the second supports are hinged end to end in a V-shape. Each elastic component includes a telescopic sleeve, a support spring, and a limiting post. The support spring is sleeved in the telescopic sleeve, and both ends of the telescopic sleeve and the support spring are fixedly installed on the support body and the inner support plate, respectively. The limiting post is sleeved in the support spring, and one end of the limiting post is fixedly connected to the inner support plate. The support device is mainly used to support the cleaning components. The water tank extends into the pipe and can be kept stable by the support device. The inner support plate is also covered with a rubber pad. The inner support plate fits against the inner wall of the pipe through the rubber pad, which can reduce the vibration generated during pulse cleaning and prevent the pipe from loosening from the surrounding soil. The support spring is used to hold the inner support plate and make it fit against the inner wall of the pipe to accommodate pipes of different diameters. The telescopic sleeve is fitted on the spring to prevent the spring from shifting when compressed. The height of the limiting post is half of the telescopic sleeve at its longest state, which is used to limit the minimum diameter of the support device entering the pipe. There are several inner support plates and first and second supports that are hinged to them, all of which are set along the axial direction of the support body.

[0006] Preferably, a guide plate is fixedly installed on the support plate, the guide plate is located between the clamping roller group and the two sets of feeding roller groups, the guide plate has a guide through hole on one side, and an anti-blocking groove on the top of the guide plate, the anti-blocking groove communicating with the guide through hole, one end of the connecting pipe is provided with a plug-in protrusion, and both the connecting pipe and the feeding rod have plug-in grooves at one end, the side of the plug-in protrusion is provided with a stepped positioning bead, the side of the plug-in groove has a positioning through hole, there are several connecting pipes, the ends of the connecting pipes are connected, and the connecting pipes and the feeding rod The device, consisting of two interlocking plates arranged vertically, includes a clamping block fixedly installed between the two plates.

One side of the T-shaped limiting strip is in contact with the outer wall of the support plate. The guide plate guides the feed rod and connecting tube to move smoothly between the clamping roller group and the two sets of feed roller groups, preventing them from deviating during movement. The anti-blocking groove and clamping groove both have the function of allowing the step positioning beads to pass through, and also play a role in maintaining the posture of the feed rod and connecting tube and preventing displacement. The two snap-fit ​​plates play the role of fixing the snap-fit ​​blocks. The feed rod and connecting tube can move in the clamping through hole. The separation block is set between the two sets of clamping roller groups. When one end of the separation block is in contact with the inner wall of the clamping through hole, the step positioning beads that have entered the clamping groove are squeezed, so that the connecting tubes and the feed rod and connecting tube are separated or connected by the two sets of clamping roller groups. The separation block is fixed and removed by the T-shaped limit strip.

The pulsed water flow passes through the water inlet, through the high-pressure water drum hose reel wrapped with the flexible hose, and enters the water delivery pipe. The high-pressure water drum hose reel serves to wind up the flexible hose.

[0008] Preferably, the two support plates are respectively provided with a first protective plate and a second protective plate at both ends. A rod-release pipe is fixedly installed on the first protective plate, with one end of the rod-release pipe passing through the first protective plate and located between two sets of pipe-feeding rollers.

The bottom of the movable base plate 3 is fixedly installed with movable wheels 24.

[0030] In use, the device is first moved to the drain outlet of the seepage pipe. The disconnecting block 12 is pushed to fit against the inner wall of the clamping through hole 10, and the T-shaped limiting strip 14 is inserted into the limiting through hole 13 to fix the disconnecting block 12. The pipe cleaning component 1 is aligned with the drain outlet, and the inner support plate 7 is pressed down, so that the entire support device 102 enters the seepage pipe. At this time, the inner support plate 7 is in contact with the inner wall of the seepage pipe under the elastic support of the support spring 602. The controller starts the two power motors 201, which drive the two pipe feeding roller groups 201 to rotate respectively. The upper and lower pipe feeding roller groups 201 rotate in opposite directions, and the feeding rod 104 clamped between the two sets of pipe feeding roller groups 201 is inserted. The pusher moves forward, and the feed rod moves through the guide plate 25, the clamping roller assembly 203, and the support through hole 22.

The connecting pipe 204 moves forward under the push of the two sets of feeding rollers 201. When the connecting pipe 204 moves into the clamping through hole 10 in the clamping block 9, the stepped positioning bead 17 is pushed inward by the disengagement block 12, which is in contact with the inner wall of the clamping through hole 10. Subsequently, the insertion protrusion 15 of the connecting pipe 204 is inserted into the insertion groove 16 of the feeding rod 104. When the stepped positioning bead 17 leaves the disengagement block 12, it will pop out in the positioning through hole 18. At this time, the connecting pipe 204 is connected to the feeding rod 104. Starting from this point, new connecting pipes 204 are continuously added so that they connect end to end to expand the cleaning depth. When the deepest part of the pipe is reached, the power motor 202 is reversed, and the two sets of pipe feeding rollers 201 drive the connecting pipes 204 and the feeding rod 104 to move backward. When the connecting pipes 204 move to the separation device 205, under the action of the separation block 12, the step positioning bead 17 located in the positioning through hole 18 is pressed down. At this time, the two connecting pipes 204 connected end to end are respectively located under the two active rollers 206 of the pipe feeding rollers 201. The two connecting pipes 204 connected end to end are separated and popped out from the release pipe 21. The above operation is repeated at each drain outlet of the seepage pipe network to complete the cleaning operation.
