Description

Technical Field

[0001] The utility model relates to the field of municipal drainage, in particular to an anti-blocking and dredging device for urban sewers. Background Art

[0002] Urban sewers are an important part of urban infrastructure, used to collect and discharge sewage and rainwater generated in the city. They are usually composed of a pipe system that runs through the entire city underground, discharging wastewater from houses, factories, commercial facilities and roads to treatment facilities or natural water bodies. However, since urban road runoff carries a large amount of impurities and foreign matter, it is very easy to cause sewer blockage, thereby affecting urban drainage. Existing devices generally add filtering devices to the drain outlets to block impurities and foreign matter outside the drain outlets. Although this method can alleviate the problem of sewer blockage to a certain extent, if the filtering device is blocked, water will accumulate on urban roads, causing urban waterlogging problems.

[0003] Therefore, a kind of anti-blocking dredging device of urban sewer is now developed for the problems referred to above. Utility Model Content

[0004] In order to overcome the disadvantages that if the existing device is blocked, it lacks the self-dredging ability, and water will accumulate on the city road, thus causing urban waterlogging, the utility model provides an anti-blocking dredging device for urban sewers.

[0005] The technical implementation scheme of the utility model is: an anti-blocking and dredging device for urban sewers, including a mounting plate, a bearing frame is connected to the top of the mounting plate, a plurality of drainage grooves are opened on the outer side of the bearing frame, a plurality of anti-blocking parts are connected to the mounting plate, guide columns are connected to the upper sides of the left and right parts of the mounting plate, a filter plate is slidably arranged between the guide columns, the filter plate is slidably connected to the drainage grooves on the bearing frame, the holes on the filter plate correspond to the positions of the anti-blocking parts, two springs are connected between the filter plate and the mounting plate, and the springs are both sleeved on the corresponding guide columns.

[0006] As an improvement of the above solution, it also includes a handle, and the handle is connected to the left and right sides of the interior of the carrying frame.

[0007] As an improvement of the above solution, a cover is further included, and the cover is clamped on the top of the carrying frame.

[0008] As an improvement of the above solution, a hidden handle is also included, and the left and right parts of the cover are rotatably provided with the hidden handle.

[0009] As an improvement of the above solution, the mounting plate is provided with water leakage holes.

[0010] As an improvement of the above solution, the upper part of the supporting frame is an outwardly protruding structure.

[0011] By adopting the above technical solution, the advantages of the utility model are:

[0012] 1. When the utility model is performing drainage treatment, the water flow will be subjected to three-level filtration treatment, so as to prevent impurities and foreign bodies from entering the sewer with the water flow to the greatest extent. At the same time, when the drainage is filtered, the filter plate is pushed downward by the gravity of the water flow, so that the drainage groove on the supporting frame is opened to prevent the water flow from being blocked and accumulating to produce water accumulation. At the same time, in this process, the anti-blocking component will also dredge the filter plate to achieve the effect of anti-blocking and dredging.

[0013] 2. The utility model is very convenient to install. It relies on the upper protruding structure of the bearing frame to be snap-connected with the drain outlet, so it can be quickly installed and disassembled, and is very convenient to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] A device for preventing and dredging urban sewers, such as Figure 1 , Figure 2 and Figure 4As shown, it includes a mounting plate 1 with leakage holes, a supporting frame 2 is connected to the top of the mounting plate 1, the upper part of the supporting frame 2 is a protruding structure, which can improve the convenience of installation, and a plurality of drainage grooves are opened on the outer side of the supporting frame 2, and a plurality of anti-blocking parts 3 are connected to the mounting plate 1, and guide columns 5 are connected to the upper sides of the left and right parts of the mounting plate 1, and a filter plate 6 is slidably arranged between the guide columns 5, and the filter plate 6 is slidably connected to the drainage grooves on the supporting frame 2, and the holes on the filter plate 6 correspond to the positions of the anti-blocking parts 3, and two springs 4 are connected between the filter plate 6 and the mounting plate 1, and the springs 4 are all sleeved on the corresponding guide columns 5.

[0021] like Figure 2 and Figure 4 As shown, a handle 7 is also included. The left and right sides of the carrying frame 2 are connected with the handle 7. The handle 7 is convenient for operators to quickly place and take the device.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a cover 8 is also included, and the cover 8 is clamped on the top of the carrying frame 2.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown in the figure, it also includes a hidden handle 9, and both the left and right parts of the cover 8 are rotatably provided with the hidden handle 9.

[0024] It should be noted that in order to avoid long-term blockage in urban sewers, the present device can be installed at the drain outlet to prevent blockage and dredge. First, press downward on the upper rear side of the hidden handle 9 so that the front end of the hidden handle 9 is tilted upward, then remove the cover 8 by pulling the hidden handle 9, and then install the supporting frame 2 by pulling the handle 7 so that the upper edge of the supporting frame 2 can be snapped into the drain outlet to complete the quick installation process. After the installation is completed, put the cover 8 back in place. When the water flows into the supporting frame 2 through the cover 8, it will be preliminarily filtered by the cover 8. The water after the preliminary filtration enters the supporting frame 2 and contacts the filter plate 6, moves downward under the filtering action of the filter plate 6, and finally completes the drainage operation through the filtration of the mounting plate 1. In this process If blockage occurs, the water flow will stagnate between the cover 8 and the filter plate 6. As the water flow increases, the filter plate 6 will be squeezed by the gravity of the water flow and begin to move downward. At this time, the spring 4 will be compressed, and as the filter plate 6 slides downward, the drainage groove on the supporting frame 2 is no longer blocked by the filter plate 6, and the water flow will begin to slowly discharge from the drainage groove to avoid long-term stagnation of water flow and blockage and water swelling. At the same time, as the filter plate 6 slides downward, the anti-blocking parts 3 will pass through the holes on the filter plate 6, thereby pushing out foreign objects blocked in the holes to achieve a dredging effect. At this time, the water flow will no longer continue to stay, and will be discharged downward through the dredged holes. At the same time, as the water flow continues to decrease, the squeezing force on the filter plate 6 is reduced, and under the action of the spring 4, the filter plate 6 will slide upward and reset.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the 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.
