[0014] By means of the above solution, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention effectively filters debris from rainwater and sewage by installing an outer filter cartridge inside the upper opening of the wellbore and an inner filter cartridge inside the middle of the outer filter cartridge. This method does not affect drainage. Rainwater flows into the upper opening of the outer filter cartridge through a rainwater grate. After initial filtration by the inner filter cartridge, larger debris is trapped inside the inner filter cartridge. The inner filter cartridge's second filter hole has a larger diameter, effectively intercepting larger debris. The filtered rainwater then flows through the second filter hole into the inner bottom of the outer filter cartridge, where smaller debris is trapped. The filtered rainwater then flows out through the first filter hole. This graded filtration mechanism, combined with the outer and inner filter cartridges, significantly improves filtration efficiency, effectively capturing and removing both larger and smaller debris, thereby effectively preventing clogging of the drainage pipe due to debris accumulation. This not only improves the treatment of rainwater and sewage but also reduces the need for drainage pipe maintenance.

[0016] 2. When the rainfall is heavy, the flow of rainwater and sewage increases, and the filter holes may not be able to meet the drainage needs. At this time, the rainwater and sewage level in the external filter cylinder will gradually increase, and eventually flow out through the overflow long hole on the outer wall of the cylinder body, thereby effectively meeting the large flow drainage needs and preventing overflow or blockage due to insufficient drainage.

[0017] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-6The utility model provides a filter bucket for municipal road drainage outlet, including an outer filter cartridge 3 installed on the inner side of the upper opening of the well shaft 1, the upper surface of the outer filter cartridge 3 is in an open state, and the lower surface of the outer filter cartridge 3 is in a closed state. The upper opening of the well shaft 1 is sequentially provided with a placement groove 11 for placing the outer filter cartridge 3 and a placement groove 2 12 for placing the rainwater grate 2 from bottom to top. The outer filter cartridge 3 is composed of an upper edge plate frame 1 31, a square funnel frame 32 and a cylinder body 33. The upper edge plate frame 1 31 is movably placed in the interior of the placement groove 11, the square funnel frame 32 is fixedly connected to the lower end of the upper edge plate frame 1 31, and the cylinder body 33 is fixedly connected to At the lower end of the square funnel frame 32, the lower end and bottom surface of the outer wall of the cylinder body 33 are penetrated by several groups of filter holes 331, and the upper end of the outer wall of the cylinder body 33 is penetrated by several groups of overflow long holes 332. A fixed frame 34 is fixedly connected to the middle position of the inner wall of the cylinder body 33, and the fixed frame 34 is located between the filter hole 1 331 and the overflow long hole 332. An inner filter cartridge 4 is movably placed on the inner side of the fixed frame 34. The upper surface of the inner filter cartridge 4 is in an open state, and the lower surface of the inner filter cartridge 4 is in a closed state. Several groups of filter holes 2 41 are penetrated by the outer wall and bottom surface of the inner filter cartridge 4. The diameter of the filter hole 2 41 is larger than the diameter of the filter hole 1 331.

[0027] The present invention effectively filters waste and debris by installing an outer filter cartridge 3 inside the upper opening of the wellbore 1 and an inner filter cartridge 4 inside the middle of the outer filter cartridge 3. This effectively eliminates waste and debris while maintaining drainage function. Rainwater flows through the rainwater grate 2 through the upper opening of the outer filter cartridge 3. After initial filtration by the inner filter cartridge 4, larger waste and debris in the rainwater are trapped within the inner filter cartridge 4. The second filter hole 41 of the inner filter cartridge 4 has a larger diameter, effectively intercepting larger waste and debris. The filtered rainwater then flows through the second filter hole 41 to the inner bottom of the outer filter cartridge 3, where smaller debris is trapped. The filtered rainwater then flows out through the first filter hole 331. Furthermore, during heavy rainfall, the flow rate of rainwater increases, and the first filter hole 331 may not be able to meet drainage requirements. In this case, the level of rainwater in the outer filter cartridge 3 gradually increases, ultimately allowing it to flow out through the overflow hole 332 on the outer wall of the cartridge body 33, effectively meeting drainage requirements and preventing overflow or blockage due to insufficient drainage.

[0028] Furthermore, the inner filter cartridge 4 adopts a funnel structure.

[0029] Specifically, the funnel-shaped inner filter cartridge 4 significantly increases its filterable area, thereby improving filtration efficiency. Furthermore, it also increases the space for accommodating waste and debris, enabling more efficient interception of waste and debris. Furthermore, the funnel structure helps direct rainwater and sewage toward the center of the inner filter cartridge 4, further improving filtration performance and reducing the accumulation of waste and debris within the inner filter cartridge 4.

[0030] Furthermore, a plurality of groups of cylindrical protrusions 44 are fixedly connected to the inner wall and the inner bottom surface of the inner filter cartridge 4 , and the plurality of groups of cylindrical protrusions 44 are evenly distributed between the plurality of groups of filter holes 331 .

[0031] Specifically, the inner filter cartridge 4 is used to filter larger garbage and debris in rainwater and sewage. By providing a plurality of groups of cylindrical protrusions 44, during the filtering process, large garbage and debris will not directly contact the inner wall of the inner filter cartridge 4, so that the filter hole 2 41 of the inner filter cartridge 4 is always in an unobstructed state, ensuring that the filter hole 2 41 can continuously and effectively filter and is not easily blocked by large garbage and debris.

[0032] Furthermore, the outer side of the upper end of the inner filter cartridge 4 is fixedly connected with an upper edge frame 42 , the inner side of the fixed frame 34 is provided with a mounting groove 341 for placing the upper edge frame 42 , and the lower surface of the fixed frame 34 is provided with a guide slope 342 .

[0033] Specifically, the inner filter cartridge 4 is movably positioned inside the fixed frame 34 via the upper edge frame 2 42, facilitating subsequent cleaning and maintenance. The function of the guide slope 342 is that when dumping the garbage and debris from the outer filter cartridge 3, the outer filter cartridge 3 needs to be inverted. At this time, the garbage and debris in the outer filter cartridge 3 will slide out along the guide slope 342, reducing the potential blind spots during cleaning, thereby making cleaning more thorough and efficient.

[0034] Furthermore, handles 43 are fixedly connected to the left and right sides of the upper surface of the upper edge frame 42.

[0035] Specifically, the handle 43 allows the inner filter cartridge 4 to be taken out of or put into the fixing frame 34 more easily.

[0036] Furthermore, a guide frame 5 is movably placed inside the upper opening of the outer filter cartridge 3 . The guide frame 5 adopts a funnel structure, and the lower surface of the guide frame 5 is lower than the lowest point of the overflow long hole 332 .

[0037] Specifically, the guide frame 5 uses a funnel structure to guide rainwater and sewage into the inner filter cartridge 4, improving the inflow efficiency of rainwater and sewage. Furthermore, the lower surface of the guide frame 5 is lower than the lowest point of the overflow slot 332. This design ensures that the guide frame 5 blocks the overflow slot 332, ensuring that, under normal flow conditions, rainwater and sewage will flow sequentially through the second and first filter holes 41 and 331, rather than directly through the overflow slot 332. Only when the flow rate of rainwater and sewage is high, exceeding normal processing capacity, will it be discharged through the overflow slot 332.

[0038] Furthermore, the outer side of the upper end of the guide frame 5 is fixedly connected to the upper edge plate frame three 51, and the inner side of the upper edge plate frame one 31 is provided with a mounting groove one 311 for placing the upper edge plate frame three 51.

[0039] Specifically, the guide frame 5 is movably placed on the inner side of the upper edge frame 1 31 through the upper edge frame 3 51 , so as to facilitate subsequent taking and placing.

[0040] Furthermore, two sets of C-shaped handles 35 are rotatably connected to the upper surface of the upper frame 31.

[0041] Specifically, the design of the C-shaped handle 35 enables the staff to conveniently grasp and operate the outer filter cartridge 3. The C-shaped handle 35 provides a stable gripping point, which facilitates the staff to effectively control when taking and placing the outer filter cartridge 3.

[0042] With this new design, workers only need to regularly clean the garbage and debris inside the outer filter cartridge 3 and inner filter cartridge 4, reducing the need for cleaning the drain ditch. To clean the garbage and debris, first remove the outer filter cartridge 3 from the shaft 1, then remove the guide frame 5, and finally remove the inner filter cartridge 4. Empty the garbage and debris trapped inside the inner filter cartridge 4, and finally empty the garbage and debris trapped inside the outer filter cartridge 3. Once emptying is complete, the inner filter cartridge 4 and guide frame 5 are sequentially installed inside the outer filter cartridge 3.

[0043] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
