Description

Technical Field

[0001] This utility model relates to the technical field of rainwater and sewage filtration, specifically a rainwater and sewage drainage filtration device. Background Technology

[0002] Drainage refers to the artificial control of water flow, the removal and treatment of excess water. Modern cities often install drainage ditches along the sides of roads for convenient and rapid drainage. To prevent pedestrians from stepping into these ditches and to act as a filter, a support filter plate is typically installed on top. Rainwater flows into the ditch through the filter holes on the plate, preventing larger pieces of household waste from entering. Smaller pieces of waste are washed into the sewers by rainwater. Over time, this accumulation of small pieces of waste in the sewers can affect the flow of sewage. Utility Model Content

[0003] To address the shortcomings of existing technologies where small debris is washed into sewers by rainwater, and the accumulation of such debris over time hinders the flow of wastewater, this invention provides a rainwater and wastewater drainage filtration device.

[0005] This utility model discloses a rainwater and sewage drainage filtration device, including a base and a manhole cover. One end of the base is provided with a lower connecting plate, and the bottom of one end of the manhole cover is provided with an upper connecting plate. The upper connecting plate and the lower connecting plate are rotatably connected by a connecting shaft. The end of the manhole cover opposite to the upper connecting plate is provided with a support rod to support the manhole cover. The base is provided with a filter basket for filtering rainwater and sewage and collecting filter residue.

[0006] As a preferred embodiment of the present invention, the filter basket includes a collection box, a bottom filter screen is provided at the bottom of the collection box, and a side filter screen is provided on the periphery of the collection box. A fixing frame is provided on the outside of the collection box, and a mounting hole is provided on the base for the bottom of the collection box to pass through. A bracket for supporting the fixing frame is provided on the periphery of the mounting hole on the base.

[0007] As a preferred embodiment of this utility model, the surface of the bracket is in close contact with the fixing frame.

[0008] As a preferred technical solution of this utility model, the upper part of the collection box is provided with a trumpet-shaped guide frame.

[0009] As a preferred embodiment of this utility model, the guide frame is provided with through slots arranged opposite to each other.

[0010] As a preferred embodiment of this utility model, both the side filter and the bottom filter are stainless steel filters.

[0011] As a preferred technical solution of this utility model, the specifications and dimensions of the mounting hole are consistent with those of the collection box.

[0012] As a preferred embodiment of this utility model, the manhole cover is equipped with a handle.

[0013] The beneficial effects of this utility model are:

[0014] This type of rainwater and sewage drainage filtration device filters rainwater flowing through the manhole cover by setting it on the base. The impurities in the filtered water remain in the filter basket. The filter basket is cleaned every once in a while to prevent it from clogging. This prevents fine debris from being washed into the sewer by rainwater. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example: Figure 1-2As shown, this utility model discloses a rainwater and sewage drainage filtration device, including a base 1 and a manhole cover 2. One end of the base 1 is provided with a lower connecting plate 3, and the bottom of one end of the manhole cover 2 is provided with an upper connecting plate 4. The upper connecting plate 4 and the lower connecting plate 3 are rotatably connected by a connecting shaft. A support rod 5 is provided at the end of the manhole cover 2 opposite to the upper connecting plate 4 to support the manhole cover 2. A filter basket 6 is provided on the base 1 to filter rainwater and sewage and collect filter residue. By setting up a filter basket on the base 1 to filter rainwater flowing through the manhole cover 2, impurities in the filtered water remain in the filter basket 6. The filter basket 6 is cleaned periodically to prevent clogging, thus preventing fine debris from being washed into the sewer by rainwater.

[0021] The filter basket 6 includes a collection box 7. The bottom of the collection box 7 is provided with a bottom filter screen 8, and the periphery of the collection box 7 is provided with side filter screens 9. A fixing frame 10 is provided on the outer side of the collection box 7. A mounting hole 11 is provided on the base 1 for the bottom of the collection box 7 to pass through. A bracket 12 for supporting the fixing frame 10 is provided around the mounting hole 11 on the base 1. Rainwater is filtered through the bottom filter screen, and the filtered rainwater is smoothly discharged into the sewer. Road debris is filtered inside the collection box 7. The sides of the collection box 7 have multiple side filter screens 9, which enhance the drainage performance of the collection box 7, allowing for filtration and drainage even when the bottom filter screen is clogged.

[0022] The upper part of the collection box 7 is provided with a trumpet-shaped guide frame 13, which can better collect sewage by expanding outward through the guide frame 13.

[0023] The guide frame 13 is provided with a corresponding through groove 14 for easy lifting. The worker pulls the handle, causing one end of the manhole cover to rotate around the connecting shaft, thus lifting the manhole cover. Then, the worker can use their hand to grip the through groove and lift the garbage bin to empty the garbage inside. This invention can filter sewage discharged into the sewer system and clean the filtered garbage inside the garbage bin periodically to prevent blockage.

[0024] Both the side filter screen 9 and the bottom filter screen 8 are stainless steel filters, which are not easily corroded or scratched by foreign objects.

[0025] The dimensions of the mounting hole 11 are consistent with those of the collection box 7, which facilitates a perfect connection between the collection box and the base.

[0026] The manhole cover 2 is equipped with a handle 15, and the manhole cover 2 has a handle groove for opening the handle 15, which facilitates opening the manhole cover.

[0027] During operation, this type of rainwater and sewage drainage filtration device filters rainwater flowing through the manhole cover 2 by setting it on the base 1. The impurities in the filtered water remain in the filter basket 6. The filtered garbage inside the filter basket 6 is cleaned every once in a while to prevent it from clogging. This can prevent fine garbage from flowing into the sewer with the rainwater.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
