[0001] The utility model relates to the technical field of drainage pipe blocking prevention, in particular to a pipe cleaning device for road drainage in municipal engineering. Background Art

[0002] Drainage pipes refer to pipes that collect and discharge sewage, wastewater and rainwater. During municipal road construction, drainage pipes need to be set up to guide and discharge sewage from the road surface. After long-term use of drainage pipes, dirt is easily accumulated inside them. In order to avoid interference with drainage, cleaning devices need to be used to clean the pipes.

[0003] When cleaning existing drainage pipes, cleaning tools or equipment are usually placed into the pipes for cleaning. The cleaning process requires personnel to manually operate multiple devices or tools, which has low cleaning efficiency. In addition, when cleaning dirt, blockage is usually discovered. At this time, the amount of impurities accumulated in the pipes is large, and cleaning is more laborious. At the same time, impurities are easily deteriorated in a high temperature environment when they are cleaned, causing odors to float out of the drain pipes, affecting air quality.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a pipe cleaning device for municipal engineering road drainage includes an anti-blocking drainage pipe 1, a water inlet pipe 2 is connected to the rear position of the top of the anti-blocking drainage pipe 1, and a cleaning component 3 is provided at the front end of the anti-blocking drainage pipe 1;

[0024] The cleaning assembly 3 includes a cleaning pipe 4, which is installed at the front end of the anti-blocking drain pipe 1 through a sealing flange. A filter screen cartridge 5 is fixedly installed inside the cleaning pipe 4. A sewage collecting frame 6 that matches the filter screen cartridge 5 is provided at the bottom end of the cleaning pipe 4. A sewage pipe 7 is connected to the bottom end of the sewage collecting frame 6, and a sewage discharge solenoid valve is provided at the connection between the sewage pipe 7 and the sewage collecting frame 6. A cleaning motor 8 is installed at the rear end of the anti-blocking drain pipe 1. The driving shaft of the cleaning motor 8 passes through the rear end of the anti-blocking drain pipe 1 and is connected to an adjusting threaded rod 9, and the end of the adjusting threaded rod 9 away from the cleaning motor 8 is rotatably connected to the filter screen cartridge 5, and the outer ring of the adjusting threaded rod 9 is threadedly connected to a cleaning scraper 10.

[0025] In this embodiment, a number of water holes are opened through the front and rear ends of the cleaning scraper 10. The outer ring of the cleaning scraper 10 is in contact with the inner walls of the anti-blocking drain pipe 1 and the cleaning pipe 4. The water holes are set to facilitate the passage of water, and the cleaning scraper 10 moves inside the anti-blocking drain pipe 1 and the cleaning pipe 4, so that most of the impurities inside them that are not washed away by the water flow are pushed to the dirt collecting frame 6, thereby improving the cleaning effect.

[0026] In this embodiment, the cleaning motor 8 is a waterproof motor, and the connection between the cleaning motor 8 and the anti-blocking drain pipe 1 is a mechanical seal. The waterproof motor can reduce the probability of the cleaning motor 8 being damaged by moisture, and the mechanical seal can prevent fluid leakage.

[0027] In this embodiment, the filter screen cartridge 5 is a hollow cylindrical setting extending in the direction of the water inlet pipe 2. A number of filter holes are evenly opened on the filter screen cartridge 5, and the opening rate is not less than 80%. The filter screen cartridge 5 is non-planar mesh setting. When the dirt is pushed by the water flow and accumulated on the filter screen cartridge 5, the dirt will only block the filter holes of the filter screen cartridge 5 from the front to the back. During this period, sewage can flow into the unblocked filter holes until all the filter holes are blocked to block the flow of sewage, thereby improving the anti-blocking effect.

[0028] In this embodiment, the front end of the cleaning pipe 4 is connected to the water outlet pipe 12, and a backwash pipe 13 is provided inside the filter screen cylinder 5. The end of the backwash pipe 13 away from the filter screen cylinder 5 passes through the top of the water outlet pipe 12 and extends out, and the end of the backwash pipe 13 away from the filter screen cylinder 5 is connected to a water pipe joint. By connecting the external cleaning water pipe to the backwash pipe 13, and then opening the external cleaning water valve, the cleaning water is transported to the filter screen cylinder 5 and sprayed out to flush the filter holes on the filter screen cylinder 5, so as to facilitate the flushing of impurities blocked in the filter holes.

[0029] In this embodiment, cleaning scrapers 11 are installed at the upper and lower ends of the outer ring of the adjusting threaded rod 9 through fixing bolts. The opposite surfaces of the two cleaning scrapers 11 are in contact with the outer ring of the filter mesh cylinder 5. The cleaning scrapers 11 rotate on the outer ring of the filter mesh cylinder 5 to facilitate scraping off impurities adhered to the outer ring of the filter mesh cylinder 5, thereby further improving the anti-blocking effect of the filter mesh cylinder 5.

[0030] In this embodiment, a plurality of equally spaced connection ports 14 are provided at the top ends of the anti-blocking drainage pipe 1 and the cleaning pipe 4, and the anti-blocking drainage pipe 1 and the cleaning pipe 4 are connected to the same exhaust pipe 15 through the connection ports 14. By connecting the exhaust pipe 15 to an external exhaust pump, it is convenient to extract the odor generated by the accumulation of impurities, avoid overflowing in large quantities from the water inlet pipe 2 and affecting the air quality around the road, and facilitate manual deodorization.

[0031] It should be noted that the present invention is a pipe cleaning device for road drainage in municipal engineering. When in use, the water inlet pipe 2 can be connected to the drainage pipe beside the road as needed, and it is ensured that the water inlet pipe 2 is the initial water inlet pipe and the water outlet pipe 12 is the water outlet pipe. Thus, when sewage such as rainwater enters the water inlet pipe 2 through the drainage channel beside the road, the sewage will enter the filter screen cylinder 5 from the filter holes on the filter screen cylinder 5 and flow out from the water outlet pipe 12, and most of the dirt will be blocked by the filter screen cylinder 5.

[0032] Furthermore, because the filter screen cartridge 5 is not arranged in a planar mesh shape and the extension direction of the filter screen cartridge 5 is opposite to the water inlet direction, the anti-clogging effect of the filter screen cartridge 5 can be effectively improved. That is, when the dirt is pushed by the water flow and accumulated on the filter screen cartridge 5, the dirt will only block the filter holes of the filter screen cartridge 5 from the front to the back. During this period, sewage can flow in from the unblocked filter holes until all the filter holes are blocked and the flow of sewage is blocked.

[0033] When cleaning is needed, a dirt collecting frame 6 is provided below the filter screen cartridge 5. The dirt collecting frame 6 collects the impurities filtered out by the filter screen cartridge 5, and a drain pipe 7 is connected below the dirt collecting frame 6. Thus, the drain solenoid valve provided between the dirt collecting frame 6 and the drain pipe 7 can be opened, and the external cleaning water pipe is connected to the backwash pipe 13.

[0034] After that, the external cleaning water valve can be opened to deliver the cleaning water to the filter screen cylinder 5 and spray it out to flush the filter holes on the filter screen cylinder 5, so as to flush out the impurities blocked in the filter holes.

[0035] At the same time, the sewage suction pipe of the external sewage pump can be connected to the sewage discharge pipe 7 as needed, so that when cleaning the filter cylinder 5, the external sewage pump can be started to extract the sewage accumulated in the sewage collecting frame 6 into the anti-blocking drainage pipe 1 and the cleaning pipe 4, completing the sewage cleaning process, avoiding a large amount of sewage from accumulating in the anti-blocking drainage pipe 1 and then deteriorating, and avoiding the generation of a large amount of toxic gas;

[0036] At the same time, during the cleaning process, the cleaning motor 8 can be started. Since the driving shaft of the cleaning motor 8 is connected to the adjusting threaded rod 9, the outer ring of the adjusting threaded rod 9 is threadedly connected to the cleaning scraper 10, and the outer ring of the cleaning scraper 10 contacts the inner wall of the anti-blocking drain pipe 1 and the cleaning pipe 4. Therefore, the adjusting threaded rod 9 can be driven to rotate by the driving shaft of the cleaning motor 8, and the thread pushes the cleaning scraper 10 to move inside the anti-blocking drain pipe 1 and the cleaning pipe 4, so that most of the impurities inside them that have not been washed away by the water flow are pushed to the dirt collecting frame 6, so as to improve the cleaning effect;

[0037] At the same time, after cleaning, it is necessary to ensure that the cleaning scraper 10 is reset again, that is, according to the above steps, the cleaning motor 8 is controlled to reverse and the cleaning scraper 10 is adjusted to the front of the water inlet pipe 2 for next use. At the same time, the cleaning scraper 11 is installed at the end of the adjusting threaded rod 9 through the fixing bolt, and the adjusting threaded rod 9 is rotatably installed on the filter screen drum 5, so that during the rotation of the adjusting threaded rod 9, the cleaning scraper 11 can be driven to rotate on the outer ring of the filter screen drum 5, so as to facilitate scraping off impurities adhered to the outer ring of the filter screen drum 5, thereby further improving the anti-blocking effect of the filter screen drum 5;

[0038] At the same time, when cleaning the filter screen cylinder 5, the anti-blocking drainage pipe 1 and the cleaning pipe 4, it is only necessary to connect multiple pipes during the initial installation, and they can be reused subsequently. Therefore, when cleaning multiple times, there is no need for personnel to use tools multiple times to perform sewage and anti-blocking operations, which is convenient for reducing the tedious steps during cleaning and improving cleaning efficiency.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
