Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, and in particular to a municipal pipeline dredging device. Background Technology

[0002] Municipal pipelines are widely used in every corner of the city, but with urban development, there are more and more trees and green plants on the roads, and fallen leaves and other debris fall from the road surface. When there is heavy rainfall, these debris are washed into the sewers by rainwater, causing blockages. Therefore, a municipal pipeline dredging device is needed to clear the blocked pipes.

[0003] However, existing patents have the following drawbacks:

[0004] (1) In order to make the spray angle of the nozzle on the central axis of the pipe, most existing utility model municipal pipeline dredging devices have a support component on the outside of the municipal pipeline dredging device, so that the municipal pipeline dredging device is supported in the pipe and the nozzle can flush out the blockage. However, most of the support components of existing municipal pipeline dredging devices are electrically controlled and require manual control and adjustment to support and move in the pipe. They cannot automatically adapt to the pipe, the operation is relatively cumbersome, and the manufacturing cost is high.

[0005] (2) Existing utility model municipal pipeline dredging devices usually have auxiliary moving rollers installed on the outside of the support components. By continuously pushing the connected water pipe into the pipeline, the municipal pipeline dredging device is pushed to move in the pipeline. Due to the large spray force of the nozzle, when encountering blockages, the municipal pipeline dredging device is not only difficult to push but may also be pushed backward due to the counter-force, affecting the speed of pipeline cleaning and reducing cleaning efficiency.

[0039] Example 1:

[0040] like Figures 1 to 6 As shown, a municipal pipeline dredging device includes: a device housing 1, a self-adjusting support assembly 2, a backflow prevention and movement assembly 3, a connecting pipe 4, and a rotating flushing assembly 5; the self-adjusting support assembly 2 is disposed on the outside of the device housing 1, the backflow prevention and movement assembly 3 is disposed on the inside of the self-adjusting support assembly 2, the connecting pipe 4 is fixedly connected to the tail end of the device housing 1, and the rotating flushing assembly 5 is disposed on the inside of the device housing 1.

[0041] The self-adjusting support assembly 2 includes a support rod 1 201, a support rod 202, a connecting pipe 203, a connecting rod 204, and a spring 1 205.

The connecting rod 204 and the connecting pipe 203 are slidably connected. The spring 1 205 is sleeved on the outer side of the connecting rod 204. One end of the spring 1 205 is fixedly connected to the inner side of the opening of the connecting pipe 203, and the other end of the spring 1 205 is fixedly connected to the end of the connecting rod 204 away from the support rod 202. The spring 1 205 supports and pushes the connecting rod 204 to insert into the inner side of the connecting pipe 203.

[0042] The anti-reverse movement assembly 3 includes a moving wheel 301, an electric push rod 305, a pressing base 307, a locking tooth 309, and a second spring 310. A rotating shaft 302 is rotatably connected to the inner side of the end of support rod 1 201 and support rod 202 away from the outer casing 1. The moving wheel 301 is fixedly connected to both ends of the rotating shaft 302. A ratchet 303 is fixedly connected to the outer side of the rotating shaft 302. A drive chamber 304 is formed inside the support rod 1 201 and support rod 2 202. The electric push rod 305 is fixedly installed inside the drive chamber 304. The silo wall has a limiting groove 306. The extrusion base 307 is slidably connected to the inner side of the limiting groove 306. The extrusion base 307 is fixedly connected to the end of the electric push rod 305. The inner side of the extrusion base 307 is fixedly connected to the limiting shaft 308. The locking tooth 309 is fixedly connected to the inner side of the extrusion base 307. The locking tooth 309 is slidably connected to the limiting shaft 308. The second spring 310 is sleeved on the outer side of the limiting shaft 308. One end of the second spring 310 is fixedly connected to the bottom end of the locking tooth 309. The other end of the second spring 310 is fixedly connected to the bottom end of the inner side of the extrusion base 307.

[0043] The rotary flushing assembly 5 includes a sealing cover 501, a motor 502, a first gear 503, a nozzle 504, and a second gear 506. The sealing cover 501 is fixedly connected to the bottom of the device housing 1. The motor 502 is fixedly installed inside the sealing cover 501. The first gear 503 is fixedly connected to both ends of the drive shaft of the motor 502. The nozzle 504 is rotatably connected to the inside of the device housing 1. A nozzle 505 is fixedly installed at the front end of the nozzle 504. The second gear 506 is fixedly connected to the outside of the nozzle 504. The second gear 506 meshes with the first gear 503.

[0044] In practical use, an external water pump and a water delivery hose are connected to the connecting pipe 4 at the tail end of the municipal pipeline dredging device, thus completing the assembly of the device. Rotating support rod 1 201 and support rod 202 causes them to move away from each other, reducing the overall cross-section of the municipal pipeline dredging device and making it longer and thinner, allowing it to be inserted into the pipeline. After insertion, spring 1 205 pushes connecting rod 204 to slide into the inner side of connecting pipe 203, causing support rod 1 201 and support rod 202 to rotate closer to each other. This increases the overall cross-sectional area of ​​the municipal pipeline dredging device, causing it to expand. The moving wheel 301 contacts the inner wall of the pipeline, supporting the device in the center of the pipeline.

[0045] Start the water pump to fill the nozzle 504 with water, and spray the water out from the nozzle 505 to flush the inner wall of the pipe and remove blockages. Start the motor 502 to drive the gear 1 503 at both ends to rotate. The gear 1 503 drives the gear 2 506 that meshes with it to rotate, so that the nozzle 504 rotates inside the device housing 1. This allows the sprayed water to rotate and flush the inner wall of the pipe, improving the cleaning effect of the blockage.

[0046] A flexible hose continuously supplies water into the pipe, propelling the municipal pipe cleaning device deeper into the pipe. Due to the anti-slip and wear-resistant properties of the moving wheel 301, the municipal pipe cleaning device can continuously move forward. The rotation of the moving wheel 301 drives the rotating shaft 302 and ratchet 303 to rotate. As the ratchet 303 rotates, it continuously compresses and contracts its matching locking teeth 309, allowing the moving wheel 301 to continue rotating forward. When encountering a blockage, the municipal pipe cleaning device will retract due to the reaction force of the water flow. At this time, the locking teeth 309 deeply engage with the ratchet 303, locking the ratchet 303 and the moving wheel 301, preventing the municipal pipe cleaning device from retracting, maintaining a good distance for flushing, and improving the unblocking effect.

[0047] After the blockage is cleared, the remote-controlled electric push rod 305 drives the compression base 307, which is fixedly connected to its end, to slide in the limiting groove 306, pulling the locking tooth 309 away from the ratchet 303, so that the moving wheel 301 can rotate freely. At this time, the municipal pipeline dredging device can be pulled out from the pipeline through the water hose, completing the recycling of the municipal pipeline dredging device.

[0048] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
