[0002] With the construction of sponge cities, more and more ecological retention ponds are being set up in urban road green belts. The purpose of setting up ecological retention ponds in green belts is to allow road rainwater to be directly discharged into the ecological retention ponds in the green belts through the perforated curbstones, thereby improving the water retention and storage capacity of sponge cities. However, during rainfall, road rainwater carrying a large amount of sediment, garbage and pollutants directly enters the ecological retention pond, affecting the service life of the ecological retention pond. In severe cases, it even causes local enrichment of pollutants and causes the death of a large number of green plants. Therefore, it is necessary to use a rainwater outlet sewage interception device to filter the rainwater.

[0003] At present, common rainwater inlet sewage interception devices usually use a filter screen combined with purified ceramsite to filter and intercept rainwater. However, during use, debris on the filter screen accumulates and is prone to clogging, making it difficult to clean, and also affecting the purification and drainage efficiency of rainwater.

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The urban green belt rainwater inlet sewage interception device according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the sewage interception device for rainwater outlets in urban green belts according to an embodiment of the utility model may include a sewage interception trough 10 , a filter cartridge 20 , a guide plate 30 , a collection basket 40 and a purification area 50 .

[0022] The bottom of the sewage interception tank 10 is provided with an outlet 11 .

[0023] The filter cartridge 20 is horizontally movably arranged inside the sewage interception tank 10. Both ends of the filter cartridge 20 are provided with shaft bodies 21. The two shaft bodies 21 are movably arranged to penetrate the inner wall of the sewage interception tank 10. A plurality of first filter holes 22 are circumferentially arranged on the filter cartridge 20, and a plurality of retractable inclined plates 23 are circumferentially arranged on the outside.

[0024] The guide plate 30 and the collecting basket 40 are respectively arranged on the symmetrical sides of the filter cartridge 20, and the guide plate 30 is extended to the outside of the sewage interception trough 10. One side of the collecting basket 40 is erected inside the sewage interception trough 10 through a frame 41, and a collecting trough 42 is arranged on the other side of the collecting basket 40. The collecting trough 42 is against the filter cartridge 20, and a second filter hole 421 is arranged at the bottom thereof.

[0025] It is understandable that the first filter hole 22 can filter the rainwater entering the sewage interception trough 10 from the guide plate 30, and the second filter hole 421 can filter the debris placed in the collection trough 42, thereby achieving the purpose of fully filtering the rainwater entering the sewage interception trough 10.

[0026] It is understandable that the collection basket 40 is overlapped with the sewage interception trough 10. When it is necessary to clean the debris in the collection trough 42, the collection basket 40 can be taken out as a whole through the frame 41, so that it can be cleaned conveniently.

[0027] The guide plate 30 and the collecting trough 42 are both provided with arc-shaped baffles 60 for telescopically limiting the inclined plate 23 .

[0028] It is understandable that when the filter cartridge 20 drives the inclined plate 23 thereon to rotate, when the inclined plate 23 rotates through the arc baffle 60, the inclined plate 23 can shrink under the action of the arc baffle 60, so that the filter cartridge 20 can rotate smoothly under the push of rainwater.

[0029] The purification zone 50 is disposed inside the sewage interception tank 10 . The purification zone 50 is located between the filter cartridge 20 and the outlet 11 . The second filter hole 421 is disposed above the purification zone 50 .

[0030] It should be noted that the purification area 50 described in this embodiment may be provided with light ceramsite, sand, gravel, activated carbon, etc. The purification area 50 can further remove pollutants in road rainwater to achieve the purpose of purifying rainwater, increase the service life of the ecological retention pond in the green belt, and ensure its normal function.

[0031] Specifically, in the actual process of intercepting rainwater, the relevant personnel first install the device at the rainwater outlet of the urban green belt, and set the guide plate 30 toward the direction of rainwater flow.

[0032] When rainwater flows toward the rainwater outlet, it can enter the sewage interception trough 10 through the guide plate 30, and the rainwater contacts the filter cartridge 20 and the inclined plate 23 on the filter cartridge 20. During this process, the impact force of the rainwater on the filter cartridge 20 and the inclined plate 23 will push the filter cartridge 20 to form a rotational torque, thereby causing the filter cartridge 20 to rotate.

[0033] After the filter cartridge 20 rotates, the debris intercepted on its surface can be transferred to the collection tank 42 in time, thereby solving the clogging problem of the filter cartridge 20, and then the sewage interception tank 10 can operate continuously and stably, improving the efficiency of rainwater treatment and drainage.

[0034] The rainwater filtered by the filter cartridge 20 and the collection tank 42 then enters the purification area 50, which can further remove pollutants in the rainwater to achieve the purpose of purifying the rainwater.

[0035] Finally, the purified rainwater can be discharged into the ecological retention pond through outlet 11.

[0036] As a possible situation, the device can be installed at rainwater outlets in urban green belts with one-way flow, river drainage outlets, etc. The device can filter and clean debris in the water flow in a timely manner. While improving the sewage interception and filtration effect, it can reduce the frequency of filter cleaning, thereby reducing manual maintenance costs and facilitating promotion and use.

[0037] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a slope 31 is provided on one side of the guide plate 30, and the slope 31 abuts against the filter cartridge 20. It can be understood that the provided slope 31 helps to increase the impact force of rainwater on the filter cartridge 20, helps the filter cartridge 20 to rotate smoothly, and transfers the intercepted debris to the collection tank 42.

[0038] In one embodiment of the present invention, Figure 3 As shown, the filter cartridge 20 is provided with a slide groove 24 for the extension and retraction of the inclined plate 23, and a spring 80 is provided in the slide groove 24. One end of the spring 80 is connected to the inner wall of the slide groove 24, and the other end of the spring 80 is connected to the inclined plate 23. One end of the inclined plate 23 is slidably arranged in the slide groove 24.

[0039] It can be understood that when the filter cartridge 20 drives the inclined plate 23 to rotate, when the inclined plate 23 passes through the arc-shaped baffle 60, the arc-shaped baffle 60 restricts the inclined plate 23, so that the inclined plate 23 squeezes the spring 80 while rotating, and finally shrinks back into the corresponding slide groove 24, so that the filter cartridge 20 can rotate smoothly.

[0040] When the inclined plate 23 is not in contact with the arc-shaped baffle 60 , the guide plate 30 and the collection basket 40 , the inclined plate 23 is stretched and reset under the action of the spring 80 .

[0041] In one embodiment of the present invention, Figure 3 As shown, a groove 422 is provided on one side of the collecting tank 42, and a brush 70 is provided in the groove 422, and the brush 70 contacts the filter cartridge 20. It can be understood that the brush 70 can brush and clean the outer wall of the filter cartridge 20 and ensure that the filter cartridge 20 rotates smoothly.

[0042] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a top cover 90 is provided on the upper side of the collection hanging basket 40, and the top cover 90 is set on the top of the sewage interception trough 10. It can be understood that the top cover 90 can protect the internal structure of the sewage interception trough 10 and limit the entry direction of rainwater, so that rainwater can enter the filter cartridge 20 from the side of the guide plate 30.

[0043] In summary, the urban green belt rainwater outlet sewage interception device of the embodiment of the utility model can push the filter cartridge to generate a rotational torque while rainwater is filtered through the filter cartridge, so that the filter cartridge rotates to transfer the intercepted debris to the collection trough in time, thereby solving the filter cartridge blockage problem, and further enabling the sewage interception trough to operate continuously and stably, thereby improving the efficiency of rainwater treatment and drainage.
