Description

Technical Field

[0001] This utility model relates to the field of municipal water supply and drainage technology, specifically to an anti-clogging device for municipal water supply and drainage. Background Technology

[0002] During use, municipal sewer systems typically discharge sewage containing a large amount of impurities, which easily accumulate in the drain pipes, leading to blockages. When blockages occur, because the pipes are laid underground, maintenance personnel cannot quickly clear them, preventing sewage from being discharged. Larger debris in the pipes cannot pass through the filters, and these larger debris cannot be broken up, causing further blockages as they flow through the pipes. Furthermore, the debris inside the pipes cannot be automatically cleared.

[0003] For example, a municipal water supply and drainage anti-clogging device with application number CN202310786274.7 and publication date 20230919 includes a well box, a drain pipe, and a filter pipe. The bottom end of the well box is fixedly connected to the drain pipe, and one end of the drain pipe outlet is fixedly connected to the filter pipe. A pre-filtration mechanism is installed inside the well box, a hydraulic component is installed inside the drain pipe, and a vibrating screen assembly is installed on the upper part of the filter pipe. The bottom end of the vibrating screen assembly is drivenly connected to a vibrating platform and a screen shaft. A rotary vibrating cylinder is rotatably connected to the circumferential side of the screen shaft. The circumferential side of the rotary vibrating cylinder is rotatably connected to the vibrating platform. The rotary vibrating cylinder is drivenly connected to the screen shaft through a reverse linkage assembly, and the circumferential side of the rotary vibrating cylinder is slidably connected to the filter pipe. This invention effectively improves the anti-clogging effect of water supply and drainage pipes by achieving the effect of water and sewage circulation, crushing, screening, and refining.

[0004] Most anti-clogging devices for water supply and drainage rely on hydraulic crushing and filter screens to intercept large particles of debris, lacking an active crushing mechanism. This leads to the accumulation of debris and blockage of pipes. Therefore, there is an urgent need to design an anti-clogging device for municipal water supply and drainage to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging device for municipal water supply and drainage, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A municipal water supply and drainage anti-clogging device includes a manhole cover assembly and a pipe treatment assembly. The manhole cover assembly and the pipe treatment assembly are connected together. The pipe treatment assembly includes a cylinder. One side wall of the cylinder has an inlet, and the other side wall of the cylinder has an outlet. An intercepting net is installed inside the outlet by bolts. A support plate is installed inside the cylinder by bolts, and a drive motor is installed at the bottom center of the support plate by bolts. A crushing shaft is installed at the output end of the drive motor by a coupling. Multiple crushing blades are evenly distributed around the circumference of the crushing shaft. A connecting seat is welded to the top center of the top of the cylinder, and a steel wire rope is installed at the top of the connecting seat by bolts. A hanger is installed at the top of the steel wire rope by bolts, and an insertion hole is opened on one side of the outer wall of the hanger.

[0008] Furthermore, a battery module is bolted to the center of the bottom of the inner wall of the cylinder, and the battery module is electrically connected to the drive motor via wires.

[0009] Furthermore, a support plate is bolted inside the cylinder, and a control module is bolted to the outer wall of the top side of the support plate. The control module is electrically connected to the battery module and the drive motor via wires.

[0010] Furthermore, a small generator is bolted to the top center of the support plate, and the small generator is electrically connected to the control module and the battery module respectively through wires.

[0011] Furthermore, the output end of the small generator is equipped with an impeller shaft via a coupling, and the impeller shaft is connected to the crushing shaft via the coupling.

[0012] Furthermore, the manhole cover assembly includes a cover body, on the outer wall of one side of the top of the cover body, there are twelve permeable holes arranged in an array, and a filter screen is embedded inside the permeable holes.

[0013] Furthermore, the bottom end of the cover is threadedly connected to a housing, and the outer wall of one side of the bottom of the housing has several through holes, and the inside of the housing is filled with an activated carbon filter element.

[0014] Furthermore, a limit rod is welded at the center of the bottom of the housing, and the hanger is installed on the outside of the limit rod through a plug hole. A limit nut is threaded to one end of the limit rod.

[0015] In the above technical solution, the anti-clogging device for municipal water supply and drainage provided by this utility model has the following advantages:

[0016] (1) By setting up a drive motor, crushing shaft and crushing blades, the drive motor directly drives the crushing shaft and the circumferentially distributed crushing blades, which can actively crush hard debris inside the cylinder and achieve multi-stage cutting of fibrous debris and tough materials. This solves the clogging problem caused by existing technologies that rely on hydraulic crushing or passive filtration, so that it can continue to work even in low flow rate or no water flow state, significantly improving the water flow efficiency of the pipeline. At the same time, the rotation of the crushing blades can prevent debris from accumulating and stagnating, reducing the risk of clogging from the source. In case of severe clogging, the pipeline treatment component can be pulled up by the hanger and wire rope to facilitate the treatment of debris inside the cylinder, and it is also convenient for workers to repair the structure in the pipeline treatment component.

[0017] (2) By setting up a small generator and impeller shaft, when the water flow is sufficient, the water will impact the impeller shaft, causing the impeller shaft to rotate. The impeller shaft will drive the small generator to rotate, generating and storing energy. When the power supply is unstable, the battery power supply can be switched. At the same time, the small generator is linked with the crushing shaft through the connecting shaft, converting the mechanical energy in the crushing process into electrical energy and storing it in the battery module, realizing energy recycling, reducing dependence on external power supply, and ensuring continuous operation.

[0018] (3) The manhole cover assembly is filled with activated carbon filter element. While filtering impurities, it adsorbs harmful gases such as hydrogen sulfide that escape from the pipe, reducing the risk of pipe corrosion. When it rains, when sewage from the road enters the water supply and drainage pipe through the manhole cover assembly, the permeable holes and filter screen initially intercept large particles of debris. Subsequently, the activated carbon filter element will filter the sewage, realizing multi-stage filtration of sewage. Attached Figure Description

The limiting rod 9 cooperates with the insertion hole 18 of the hanging device 17, and the pipe processing assembly 2 is locked by the limiting nut 10 to ensure that the cylinder 11 is vertically suspended in the drainage pipe.

[0030] This utility model provides an anti-clogging device for municipal water supply and drainage.
