Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage equipment, in particular to a filtering device for municipal ditch drainage. Background Technique
[0002] The municipal ditch system is an important part of the urban drainage system. An orderly planned and densely arranged ditch system can effectively drain the accumulated water on the urban road surface. In bad weather such as heavy rain, if the urban road lacks an effective ditch drainage system, a large amount of water will accumulate, which will further lead to flood risks in low-lying areas, causing public or private property losses. In severe cases, even casualties may occur. Therefore, when the city develops and expands, the ditch drainage system must also be designed synchronously.
[0003] Most of the current ditch drainage systems only have a single filtering method of ditch covers, which only intercept and filter large sundries, or filter stations are set between two ditches with a certain distance. The filtering is not timely. While the ditch system bears silt, a large amount of fine sand and gravel will also accumulate in the ditch, which is extremely easy to cause the ditch channel to be blocked, thereby greatly affecting the drainage function.
[0004] In order to solve the above problems, we made improvements and proposed a filtering device for municipal ditch drainage. Content of the Utility Model
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] The utility model provides a filtering device for municipal ditch drainage, including a filter box. The top surface of the filter box is detachably provided with a box cover. Both the left and right top ends of the filter box are fixedly welded with channel filter plates. The size of the channel filter plates is similar to the cross-section of the ditch. The front and rear ends of the top surface of the box cover are fixedly welded with handles. The top of the box cover is detachably provided with an anti-tripping pedal. The top end inside the filter box is detachably provided with a filter box. The height of the filter box is close to half of the height of the filter box, and its length and width are smaller than the length and width of the filter box.
[0007] As a preferred technical solution of the utility model, the surfaces of the filter box, the box cover and the anti-tripping pedal are evenly distributed with water leakage holes. The length and width of the anti-tripping pedal are equal to the length and width of the box cover. The front and rear ends of the bottom surface of the box cover are fixedly welded with L-shaped plates.
[0008] As a preferred technical solution of the utility model, the front and back top ends of the filter box are fixedly welded with inserting strips. The box cover is slidably and detachably connected to the filter box through the inserting strips and the L-shaped plates. The front and rear ends of the top surface of the anti-tripping pedal are respectively provided with handle through holes. The plane positions of the two handle through holes are the same as and aligned with the handles.
[0009] As a preferred technical solution of the present utility model, holding grooves are formed at the tops of the left and right ends of the anti-tripping pedal, and four limiting cylinders are fixedly welded to the top surface of the box cover, and the four limiting cylinders are respectively located at the four corner positions of the top surface of the box cover.
[0010] As a preferred technical solution of the present utility model, four limiting tubes are fixedly welded to the bottom surface of the anti-tripping pedal, and the four limiting tubes are respectively located at the four corner positions of the bottom surface of the anti-tripping pedal. The cross-sectional dimension of the limiting tube is equal to the inner diameter of the limiting cylinder, and the anti-tripping pedal is detachably connected to the box cover through the limiting cylinder and the limiting tube.
[0011] As a preferred technical solution of the present utility model, a support bar is circumferentially welded to the inner wall of the top end of the filter box. An L-shaped edge is provided at the top end of the filter box. The filter box is erected at the top end inside the filter box through the support bar and the L-shaped edge. A handle is fixedly arranged in the middle of the top surface of the L-shaped edge of the filter box by screws. A gravel filter screen is fixedly arranged on the bottom surface of the filter box, and a channel filter screen is fixedly arranged in the middle of the channel filter plate.
[0012] The beneficial effects of the present utility model are as follows: For the filtering device for municipal ditch drainage, by changing the basic municipal ditch plate to a filter box with a cover, the internally equipped filter box and the external channel filter plate can filter fine gravel and sundries in the water twice in a graded manner to prevent blockage of the ditch drainage system. Its installation principle is simple, the disassembly is convenient, and the maintenance is fast and convenient. At the same time, an anti-tripping pedal higher than the handle is added, which effectively prevents maintenance personnel or passers-by from being tripped and injured, and also plays a certain protective role for the filter box.

[0019] The following is a description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0020] Embodiment: As Figures 1-4 shown, a filtering device for municipal ditch drainage includes a filter box 1. A box cover 2 is detachably arranged on the top surface of the filter box 1. Channel filter plates 3 are fixedly welded to the top ends of the left and right sides of the filter box 1. The size of the channel filter plates 3 is similar to the cross-section of the ditch. Handles 4 are fixedly welded to the front and rear ends of the top surface of the box cover 2. An anti-tripping pedal 5 is detachably arranged on the top of the box cover 2. A filter box 13 is detachably arranged at the top end inside the filter box 1. The height of the filter box 13 is close to half of the height of the filter box 1, and its length and width are smaller than the length and width of the filter box 1.
[0021] Leakage holes are evenly distributed on the surfaces of the filter box 1, the box cover 2 and the anti-tripping pedal 5. The length and width of the anti-tripping pedal 5 are equal to the length and width of the box cover 2. L-shaped plates 6 are fixedly welded to the front and rear ends of the bottom surface of the box cover 2.
[0022] Insertion strips 7 are fixedly welded to the top ends of the front and back sides of the filter box 1. The box cover 2 is slidably and detachably connected to the filter box 1 through the insertion strips 7 and the L-shaped plates 6. Handle through-holes 8 are penetrated through the front and rear ends of the top surface of the anti-tripping pedal 5. The plane positions of the two handle through-holes 8 are the same as and aligned with the handles 4.
[0023] Gripping grooves 9 are formed at the top ends of the left and right sides of the anti-tripping pedal 5. Four limiting cylinders 10 are fixedly welded to the top surface of the box cover 2. The four limiting cylinders 10 are respectively located at the four corner positions of the top surface of the box cover 2.
[0024] Four limiting pipes 11 are fixedly welded to the bottom surface of the anti-tripping pedal 5. The four limiting pipes 11 are respectively located at the four corner positions of the bottom surface of the anti-tripping pedal 5. The cross-sectional dimension of the limiting pipe 11 is equal to the inner diameter of the limiting cylinder 10. The anti-tripping pedal 5 is detachably connected to the box cover 2 through the limiting cylinders 10 and the limiting pipes 11.
[0025] Support strips 12 are welded around the inner wall of the top end of the filter box 1. An L-shaped edge is arranged at the top end of the filter box 13. The filter box 13 is erected at the top end inside the filter box 1 through the support strips 12 and the L-shaped edge. A handle is fixedly arranged in the middle of the top surface of the L-shaped edge of the filter box 13 by screws. A gravel filter screen 14 is fixedly arranged on the bottom surface of the filter box 13. A channel filter screen 15 is fixedly arranged in the middle of the channel filter plate 3.
[0026] Working principle: When this kind of filtering device for municipal ditch drainage is in use, a stepped groove needs to be opened at the top edge of the ditch. The depth is equal to the sum of the thickness of the box cover 2, the height of the limiting cylinder 10, the thickness of the anti-tripping pedal 5, and the height of the L-shaped plate 6. The width of the stepped groove is equal to the width difference between the box cover 2 and the filter box 1. The filter box 13 is placed on the support bar 12 of the filter box 1. Then, the filter box 1 is slid into the L-shaped plate 6 of the box cover 2 through the insertion bar 7. Next, the filter box 1 is installed at the top end in the ditch through the handle 4. At this time, the channel filter plate 3 touches the bottom. Finally, the limiting tube 11 of the anti-tripping pedal 5 is aligned with the limiting cylinder 10 and inserted to complete the placement and installation of the anti-tripping pedal 5. At this time, the top surface of the anti-tripping pedal 5 should be flush with the ground surface, and the installation can be completed. The box cover 2, the anti-tripping pedal 5, and the filter box 1 can all ensure that when rainwater leaks, large fallen leaves, stones and other sundries will not fall in. The sand filter screen 14 of the internal filter box 13 can filter and intercept relatively fine sand and other sundries in the water and accumulate in the filter box 13. During later maintenance, it can be taken out and cleaned through the handle at the top of the filter box 13. The channel filter plate 3 and the channel filter screen 15 play a role in further filtering and intercepting finer sundries.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
