Description

Technical Field

[0001] The present application relates to the technical field of pipeline dredging, and in particular to an underground drainage pipe network dredging device. Background Art

[0002] In order to reduce urban waterlogging during the rainy season, cities generally build rainwater drainage systems along the roads to form an urban underground pipe network. That is, prefabricated reinforced concrete pipes are buried at a certain depth underground, and the road surface water is collected through vertical drainage outlets and discharged to rivers or depressions through the rainwater drainage system.

[0003] In the existing underground drainage network, the entrance position of the dredging pipe is first determined, and the dredging equipment is placed in the shaft. Then, the equipment is manually pulled into the pipe network, and the high-pressure water gun in the dredging device is turned on to clean the inside of the pipe to flush out the scale, dirt and sediment on the inner wall of the pipe. During the cleaning process, the sludge will be discharged into the shaft. After the dredging is completed, the sludge in the shaft is extracted and collected using a sludge pipe, waiting for the next step of processing. Finally, the drainage pipe needs to be inspected and evaluated to ensure the normal operation of the pipe.

[0004] When cleaning the existing pipe network, water flow impact is mostly used to discharge the silt. However, if the silt forms hard lumps or blockages in the pipes, the impact force of the water flow may not be able to effectively break it up or remove it, and it may form a blockage again, which directly affects the operation of the entire drainage system and is quite inconvenient. Utility Model Content

[0005] The purpose of the present application is to provide an underground drainage pipe network dredging device to solve the problem that if silt forms hard lumps or blockages in the pipe, the impact force of the water flow may not be able to effectively break it up or remove it.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A device for dredging an underground drainage pipe network comprises a base plate, two rollers 1 are symmetrically connected to the two sides of the base plate for rotation, a water tank is fixedly connected to the top of the base plate, a water inlet pipe is fixedly connected to one side of the water tank, the water inlet pipe is communicated with the water tank, a water pump is arranged inside the water tank, a water outlet end of the water pump is fixedly connected to a water outlet pipe, the water outlet pipe is communicated with the water pump, one end of the water outlet pipe away from the water pump passes through the water tank and is fixedly connected to a nozzle 1, a plurality of nozzles 2 are fixedly connected to the outer surface of the nozzle 1 at equal intervals, a crushing mechanism is arranged on the top of the water tank, and an intercepting mechanism is arranged on the bottom of the base plate.

[0008] By adopting the above technical scheme, the dredging device is placed in the vertical shaft, and then the dredging device is placed in the pipeline by manual traction, and then water is supplied to the water tank through the water inlet pipe, and the water flow is sprayed out from nozzles one and two through the water pump. Nozzle one flushes and removes the silt and blockages in the pipeline, while nozzle two removes the dirt and solid particles deposited on the pipeline wall. By pushing the water inlet pipe, the bottom plate is subjected to force, so that it moves inside the pipeline under the action of roller one, so as to facilitate dredging of various positions inside each pipeline. When the pipeline is dredged, the lumps in the pipeline can be crushed by the crushing mechanism, and the silt in the pipeline can be taken out by the intercepting mechanism, thereby further improving the dredging effect.

[0010] By adopting the above technical solution, the rotating motor is started to drive the driving rod to rotate, and the driving rod rotates to drive the first crushing knife to rotate, and the rotation of the first crushing knife will drive the second crushing knife to rotate, so that the lumps in the pipeline are crushed into smaller particles, which are convenient for being taken out by water flow for treatment.

[0011] Furthermore, a surface of the second crushing knife away from the first crushing knife is fixedly connected with a plurality of blades at equal intervals.

[0012] By adopting the above technical solution, the cutting efficiency is further improved.

[0014] By adopting the above technical solution, the impact force of the agglomeration on the rotating motor is reduced by the damping shock absorber.

[0015] Furthermore, two rubber pads are symmetrically fixedly connected to a side of the base close to the damping shock absorber, and one end of the rubber pad away from the base is fixedly connected to the damping shock absorber.

[0018] By adopting the above technical solution, roller 2 can move on the crushed particles, and the interception plate brings the particles out of the pipeline, further reducing the risk of sludge flowing to other parts of the pipeline and causing blockage.

[0019] Furthermore, one side of the bottom of the base plate is arranged as an inclined surface, and the second roller is installed on the inclined surface.

[0020] By adopting the above technical solution, the second roller is inclined, which makes it easier for the second roller to move on the crushed particles.

[0021] Furthermore, the thickness of one end of the transverse plate away from the intercepting plate gradually decreases.

[0022] By adopting the above technical solution, the transverse plate can be easily moved to the bottom of the particles, so that the particles can be taken out and cleaned by the interception plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, a rotating motor is started to drive a driving rod to rotate, and the rotation of the driving rod drives the first crushing knife to rotate, and the rotation of the first crushing knife will drive the second crushing knife to rotate. The first crushing knife and the second crushing knife can crush the lumps in the pipeline into smaller particles, thereby increasing the channel for water flow, making it easier for the lumps to be washed out with the water flow, thereby improving the water flow rate and effect of the underground pipe network.

[0025] 2. In this application, after the crushing is completed, the horizontal plate moves to the bottom of the particles, and then the interception plate pushes the particles to move, thereby taking the particles out, further reducing the risk of silt flowing to other parts of the pipeline and causing blockage, improving the smoothness of water flow, and ensuring the normal operation of the pipeline.

[0035] When it is necessary to clean the underground pipe network, first put the bottom plate 1 into the shaft, then put the bottom plate 1 into the pipe by manual traction, then deliver water to the water tank 3 through the water inlet pipe 4, and spray water from the nozzle 1 6 and the nozzle 2 7 through the water pump. The nozzle 1 6 flushes and removes the silt and blockages in the pipe, while the nozzle 2 7 removes the dirt and solid particles deposited on the pipe wall, thereby ensuring the overall smoothness of the pipe. By pushing the water inlet pipe 4, the bottom plate 1 is subjected to force, so that it moves inside the pipe under the action of the roller 1 2, which is convenient for dredging various positions inside each pipe. When dredging the pipe, the lumps in the pipe can be crushed by the crushing mechanism, so that the solid blockages can be removed more easily. The silt in the pipe can be brought out by the intercepting mechanism, which further improves the dredging effect.

[0036] Reference Figure 2 , Figure 3 and Figure 4The crushing mechanism includes a driving box 8 fixedly connected to the top of the water tank 3, a base 9 is arranged inside the driving box 8, a rotating motor 10 is fixedly connected to the top of the base 9, a driving rod 11 is fixedly connected to the output end of the rotating motor 10, the driving rod 11 penetrates the driving box 8 and is fixedly connected to a crushing knife 12, a side of the crushing knife 12 away from the driving rod 11 is fixedly connected to a crushing knife 2 13, the crushing knife 12 and the crushing knife 2 13 are arranged in a cross, and a buffer is arranged at the bottom of the base 9.

[0037] Among them, a side of the crushing knife 2 13 away from the crushing knife 1 12 is fixedly connected with a plurality of blades 14 at equal intervals.

[0038] In addition, the buffer component includes a slide plate 22 fixedly connected to the inner bottom wall of the drive box 8, and slide grooves 17 are opened on both sides of the top of the slide plate 22. Slide blocks are fixedly connected to both sides of the bottom of the base 9, and the slide blocks are slidably connected to the base 9. Damping shock absorbers 15 are fixedly connected to both sides of the inner wall of the drive box 8, and the damping shock absorbers 15 are fixedly connected to the base 9.

[0039] In addition, two rubber pads 16 are symmetrically fixedly connected to a side of the base 9 close to the damping shock absorber 15 , and one end of the rubber pad 16 away from the base 9 is fixedly connected to the damping shock absorber 15 .

[0040] When the pipeline is dredged, the rotating motor 10 is started to drive the driving rod 11 to rotate, and the driving rod 11 rotates to drive the crushing knife 1 12 to rotate, and the crushing knife 1 12 rotates to drive the crushing knife 2 13 to rotate. The crushing knife 1 12 and the crushing knife 2 13 can crush the lumps in the pipeline into smaller particles, thereby increasing the channel for water flow to pass through, making it easier for the lumps to be washed out with the water flow, thereby improving the water flow rate and effect of the underground pipe network. When crushing the lumps, the blade 14 is set on the side of the crushing knife 12, and the blade 14 can increase the cutting force on the lumps and effectively cut them into smaller particles. When the crushing blade 13 contacts the agglomerates, the crushing blade transmits pressure to the driving rod 11, and the driving rod 11 transmits pressure to the rotating motor 10, so that the rotating motor 10 moves on the top of the slide plate 22, thereby squeezing the damping shock absorber 15, and then the damping shock absorber 15 buffers and offsets the energy generated by the movement of the rotating motor 10, thereby reducing the impact force on the rotating motor 10 and reducing the damage to the rotating motor 10. A rubber pad 16 is provided between the rotating motor 10 and the damping shock absorber 15, and the rubber pad 16 can play a role of buffering and shock absorption, further reducing the impact force on the rotating motor 10.

[0042] Among them, one side of the bottom of the bottom plate 1 is set as an inclined surface, and the second roller 19 is installed on the inclined surface.

[0043] In addition, the thickness of one end of the transverse plate 21 away from the intercepting plate 20 gradually decreases.

[0044] After the crushing is completed, the roller 2 19 can move on the crushed particles, thereby reducing the risk of particles blocking the movement of the bottom plate 1, so that the bottom plate 1 can enter the interior of the pipeline for cleaning. When the internal dredging of the pipeline is completed, the staff pulls the water inlet pipe 4 to make the bottom plate 1 slowly move out of the pipeline. During the movement, the connecting plate 23 is driven downward by starting the electric push rod 24, and the downward movement of the connecting plate 23 drives the intercepting plate 20 to move downward, so that the cross plate 21 moves to the bottom of the particles, and then the particles are pushed to move through the intercepting plate 20, so that The particles are taken out, and the risk of silt flowing to other parts of the pipeline and causing blockage is further reduced, the smoothness of water flow is improved, and the normal operation of the pipeline is ensured. The bottom ends of the intercepting plate 20 and the transverse plate 21 are both set as arc surfaces, so that the intercepting plate 20 and the transverse plate 21 can better fit the shape of the underground drainage pipe. The roller 2 19 is fixed to the bottom of the slope, so that the roller 2 19 is inclined, which makes it easier for the roller 2 19 to move on the crushed particles. The thickness of the transverse plate 21 is gradually reduced, so that the transverse plate 21 can better enter the bottom of the particles, so that they are taken out for cleaning by the intercepting plate 20.

[0046] Roller 2 19 can move on the crushed particles, thereby reducing the risk of particles blocking the movement of the bottom plate 1, so that the bottom plate 1 can enter the interior of the pipeline for cleaning. After the internal pipeline is unblocked, the staff pulls the water inlet pipe 4 to make the bottom plate 1 slowly move out of the pipeline. During the movement, the connecting plate 23 is driven downward by starting the electric push rod 24, and the downward movement of the connecting plate 23 will drive the intercepting plate 20 to move downward, so that the cross plate 21 moves to the bottom of the particles, and then the particles are pushed to move by the intercepting plate 20, so as to bring the particles out, further reducing the risk of silt flowing to other parts of the pipeline and causing blockage, thereby ensuring the normal operation of the pipeline.
