Description

Technical Field

[0001] This invention relates to the field of pipe dredging technology, and in particular to a device for treating blockages in drainage pipes. Background Technology

[0002] When using existing high-pressure water jets to clear blockages in municipal pipelines, the impact force of the high-pressure water flow can easily exceed the pressure-bearing limits of old or fragile pipes, especially PVC pipes, which can easily cause pipe wall rupture. Simultaneously, the high-speed rotating high-pressure water jet continuously rubs against the pipe wall, causing significant damage. Furthermore, because the high-pressure water jet is pulled by a flexible water pipe, it is prone to swinging and striking the inner wall of the pipe, which can also easily cause pipe damage. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] The outer wall of the waterproof cylinder is provided with a plurality of push rod motors in a circular array. The output end of each push rod motor is fixedly connected to the arc-shaped anti-slip plate. A pressure sensor is provided at the connection position between the push rod motor and the arc-shaped anti-slip plate.

[0013] Furthermore, the stable puncture and cleaning mechanism also includes a rotating plate rotatably connected to the inner wall of the waterproof cylinder. A toothed ring is fixed on one side of the rotating plate, and a gear meshes on one side of the toothed ring. A motor is fixed to the inner wall of the waterproof cylinder, and the output end of the motor is fixedly connected to the gear. The gear meshes with the toothed ring.

[0014] The reciprocating screw has a water pipe hole inside;

[0015] The reciprocating screw is threaded with a movable plate, and the movable plate is fitted with multiple guide rods inside. The multiple guide rods are fixedly connected to the waterproof cylinder, and a connecting ring is fixed to one end of each guide rod.

[0016] Furthermore, the stable puncture cleaning mechanism also includes a channel opened in the drill bit, a high-pressure nozzle one is embedded in the front end of the drill bit, and a high-pressure nozzle two corresponding to the number of scrapers is fixed in a circular array on the outer wall of the drill bit, and the liquid sprayed by the high-pressure nozzle two contacts the scrapers.

[0017] The channel is connected to high-pressure nozzle one and high-pressure nozzle two respectively. One end of the channel is connected to a high-pressure telescopic tube. The high-pressure telescopic tube includes an inner tube and an outer tube. The outer tube is connected to the channel through a rotary seal. The piston of the inner tube is sleeved inside the outer tube. One end of the inner tube is connected to a water pipe connector.

[0018] The high-pressure telescopic tube is fitted inside the water pipe hole one.

[0019] Furthermore, the pipeline cleaning and anti-rush protection mechanism also includes a support cylinder rotatably connected to one side of the moving plate. One side of the support cylinder has a shaped hole that matches the shaped rod. The support cylinder is sleeved inside the connecting ring. The other side of the support cylinder is rotatably connected to the moving plate. The shaped rod has a second water pipe hole inside. The high-pressure telescopic pipe is sleeved inside the second water pipe hole.

[0020] Furthermore, the pipeline cleaning anti-rush protection mechanism also includes a docking cylinder fixed to one side of the support cylinder.

[0023] Compared with existing technologies, the beneficial effects of this invention are:

[0024] 1. This invention solves the problem of drill bit contact with pipe wall and drill bit swinging and hitting the pipe wall by installing a pipe anti-wear limiting mechanism, so that the rotating drill bit coincides with the central axis of the pipe. It effectively avoids the risk of pipe wall damage caused by drill bit rotating and scraping the inner wall of the pipe and swinging and hitting the pipe wall in the prior art.

[0025] 2. This invention utilizes a pipe cleaning anti-impact protection mechanism to peel dirt from the pipe as the scraper rotates. The high-pressure nozzle and scraper rotate synchronously, always remaining on the same plane. The liquid sprayed from the high-pressure nozzle impacts the dirt scraped off by the scraper, while the scraper simultaneously blocks the high-pressure liquid, preventing it from directly impacting the pipe wall and causing damage. When the liquid impacts the scraper, it not only separates the surface dirt but also disperses the dirt, flushing it out of the pipe with the water flow. Furthermore, a diversion slope diverts the high-pressure liquid, allowing the water to contact the inner wall of the pipe along the slope, thoroughly cleaning the pipe while forming a protective layer and effectively preventing pipe wall damage.

[0048] The stable puncture cleaning mechanism 3 also includes a channel opened in the drill bit 311. A high-pressure nozzle 313 is embedded in the front end of the drill bit 311. A high-pressure nozzle 312 corresponding to the number of scrapers 47 is fixed in a circular array on the outer wall of the drill bit 311. The liquid sprayed by the high-pressure nozzle 312 comes into contact with the scraper 47.

[0049] The channel is connected to high-pressure nozzle 313 and high-pressure nozzle 312 respectively. One end of the channel is connected to a high-pressure telescopic tube 314. The high-pressure telescopic tube 314 includes an inner tube and an outer tube. The outer tube is connected to the channel through a rotary seal. The piston of the inner tube is sleeved inside the outer tube. One end of the inner tube is connected to the water pipe connector 24.

[0050] The high-pressure telescopic pipe 314 is fitted inside the water pipe hole 36.

[0051] The pipeline cleaning and anti-rush protection mechanism 4 also includes a support cylinder 43 rotatably connected to one side of the movable plate 38. One side of the support cylinder 43 is provided with a shaped hole 44 that matches the shaped rod 41. The support cylinder 43 is sleeved inside the connecting ring 310. The other side of the support cylinder 43 is rotatably connected to the movable plate 38. The shaped rod 41 is provided with a water pipe hole 42 inside. The high-pressure telescopic pipe 314 is sleeved inside the water pipe hole 42.

[0052] The pipeline cleaning anti-rush protection mechanism 4 also includes a docking cylinder 45 fixed on one side of the support cylinder 43. The outer wall of the docking cylinder 45 has a circular array of multiple push rod motors 46. The output end of the push rod motors 46 is fixedly connected to the scraper 47. A pressure sensor is provided at the connection position between the push rod motors 46 and the scraper 47.

[0053] The high-pressure telescopic tube 314 is sleeved inside the docking cylinder 45. The drill bit 311 is fixedly connected to the docking cylinder 45. A pressure sensor is installed at the connection position between the drill bit 311 and the docking cylinder 45.

[0054] The control module inside the mobile vehicle 11 is electrically connected to the motor 33, the push rod motor 1 22 and the push rod motor 2 46 respectively, and the mobile vehicle 11 is connected to an external controller.

[0055] Working principle:

[0056] The controller controls the mobile cart 11 to move within the pipe that needs dredging. A camera on the mobile cart 11 captures the conditions inside the pipe. Once it reaches the desired dredging location, the mobile cart 11 stops moving, and the pusher motor 22 is activated to push the curved anti-slip plate 23 closer to the pipe wall. The lower curved anti-slip plate 23 first contacts the bottom of the pipe wall. After contact, it drives the pipe anti-wear limiting mechanism 2, the stabilizing puncture cleaning mechanism 3, and the pipe cleaning anti-impact protection mechanism 4 via the slide rail 13 and slider 14. Once all the curved anti-slip plates 23 have contacted the inner wall of the pipe, and all pressure sensors have reached their pressure thresholds, multiple pusher motors 22 are shut off.

[0057] At this time, the pipeline anti-wear limiting mechanism 2, the stable puncture cleaning mechanism 3, and the pipeline cleaning anti-impact protection mechanism 4 are all precisely positioned on the central axis of the pipeline, effectively avoiding the risk of pipe wall damage caused by the rotation of the drill bit scraping the inner wall of the pipeline in the existing technology.

[0058] Multiple push rod motors 46 are activated to push the scraper 47 to adhere to the inner wall of the pipe. Multiple pressure sensors 3 stop moving after acquiring pressure. Control motor 33 drives gear 34 to rotate. The rotation of gear 34 drives gear ring 32 and rotating plate 31 to rotate. Rotating plate 31 drives reciprocating screw 35 and shaped rod 41 to rotate. The rotation of reciprocating screw 35 causes moving plate 38 to push support cylinder 43, scraper 47, and drill bit 311 to move horizontally. During this movement, shaped rod 41 drives support cylinder 43 to rotate through shaped hole 44. Support cylinder 43 drives docking cylinder 45, push rod motors 46, scraper 47, and drill bit 311 to rotate, supplying water to drill bit 311. Water is then sprayed out through high-pressure nozzles 312 and 313. Drill bit 311 and high-pressure nozzle 313 face forward. During the cleaning process, the scraper 47 rotates to separate the dirt from the pipe. The high-pressure nozzle 312 and the scraper 47 rotate synchronously and remain on the same plane. The liquid sprayed from the high-pressure nozzle 312 impacts the dirt scraped off by the scraper 47. At the same time, the scraper 47 blocks the high-pressure liquid to prevent it from directly hitting the pipe wall and causing damage. When the liquid impacts the scraper 47, it not only separates the surface dirt but also disperses the dirt and discharges it into the pipe with the water flow. In addition, the diversion slope 48 diverts the high-pressure liquid, allowing the water to contact the inner wall of the pipe along the diversion slope 48. This thoroughly cleans the pipe and forms a protective layer, effectively preventing damage to the pipe wall. After cleaning this position, the push rod motor 22 and the push rod motor 46 are retracted, and the moving vehicle 11 is moved to the next position for unblocking.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
