In addition, the device structure is complex, and the sewage interception frame is difficult to clean after being blocked by mud and sand, making it difficult to promote and use.

[0006] In view of this, the defects of the device are studied and improved, and a sponge city road rainwater interception device is provided in order to achieve a more practical purpose. Summary of the Invention

[0007] The present invention aims to provide an easy-to-clean and detachable sponge city road rainwater interception device to solve the problems that the existing rainwater interception device is not tightly connected with the sponge city green rainwater facilities, the device structure is complex, and it is difficult to clean.

[0008] The technical solution of the present invention:

[0009] Sponge city road rainwater sewage interception device, including sewage interception frame, grate, baffle, detachable filter unit, its characterized in that: the sewage interception frame inside is sequentially provided with grate, baffle and detachable filter unit from top to bottom, sewage interception frame one side is equipped with water inlet, and the other side lower part is provided with first water outlet, and upper part is provided with second water outlet;The detachable filter unit is composed of first detachable filter unit and second detachable filter unit, the first detachable filter unit is composed of bottom plate and a plurality of vertical rods, and the second detachable filter unit is a perforated pad, and the number and size of the perforation are matched with the first detachable filter unit;

[0010] Further, the water inlet is provided with 2-4 vertical rods, and the water inlet is separated into 3-5 holes.

[0011] Further, the grate and the baffle are installed at an angle of 10-20° with the horizontal plane.

[0012] The advantages of the present application are: by optimizing the main structure of the sewage interception frame, the detachable filter unit is increased, the residence time of rainwater in the sewage interception frame is prolonged, the replacement difficulty of the sewage interception frame is reduced, the post-cleaning is facilitated, the service life is increased, the use and popularization are easy, and the waste of manpower and material resources is reduced.The solution of these problems has important significance for accelerating the construction of sponge city and solving the practical application problems of road green rainwater treatment facility sewage interception frame.

[0020] The embodiments are described below in conjunction with the drawings.

[0021] Figure 1 As shown: sponge city road rainwater sewage interception device, including sewage interception frame 1, grate 5, baffle 6, detachable filter unit 7. The inside of sewage interception frame 1 is sequentially provided with grate 5, baffle 6 and detachable filter unit 7 from top to bottom, one side of sewage interception frame 1 is provided with water inlet 2, the other side is provided with first water outlet 3 at lower part and second water outlet 4 at upper part; 2-4 vertical rods are arranged on water inlet 2, which divides water inlet 2 into 3-5 holes; detachable filter unit 7 is composed of first detachable filter unit and second detachable filter unit, first detachable filter unit is composed of bottom plate 701 and a plurality of vertical rods 703, second detachable filter unit is perforated pad 702, the number and size of the perforations are matched with first detachable filter unit; grate 5 and baffle 6 are installed at an angle of 10-20° with horizontal plane.

[0022] Rainwater on the road enters sewage interception frame 1 through water inlet 2, firstly passes through grate 5, then passes through baffle 6 to enter the lower part of sewage interception frame 1, the lower part of sewage interception frame 1 is provided with detachable filter unit 7, rainwater is filtered and enters sponge city green infrastructure 10 through first water outlet 3. Grate 5 and baffle 6 are installed at an angle of 10-20° with horizontal plane, for grate 5, rainwater can be made to fall to the bottom of sewage interception frame first, instead of directly passing through second water outlet 4 to enter sponge city green infrastructure 10; for baffle 6, it can make the deposited solid substances slide to the bottom of sewage interception frame, avoiding that more solid substances are deposited on baffle 6 to affect subsequent use.

[0023] Figure 2 As shown: 2-4 vertical rods are arranged on water inlet 2, which divides water inlet 2 into 3-5 holes, which can intercept large plastic bags, branches and the like into sewage interception frame.

[0024] Figure 3 As shown: detachable filter unit 7 is composed of first detachable filter unit and second detachable filter unit. First detachable filter unit is composed of bottom plate 701 and a plurality of vertical rods 703, vertical rods 703 can slow down the flow rate of rainwater, so that fine particles in rainwater are deposited; second detachable filter unit is perforated pad 702, the number and size of the perforations are matched with first detachable filter unit. Detachable filter unit 7 can be put into or taken out of sewage interception frame through first water outlet 3.

[0025] Figure 4 、 Figure 5 As shown: when more solid impurities are deposited on detachable filter unit 7, detachable filter unit 7 can be taken out of sewage interception frame 1, and first detachable filter unit and second detachable filter unit are separated, and solid impurities are removed with the help of second detachable filter unit.

[0026] Figure 1 , Figure 6 As shown in the figure, when the detachable filter unit 7 is blocked or the rainfall is large, rainwater can exceed the grate 5 and enter the sponge city green infrastructure 10 through the second water outlet 4, without affecting normal rainwater discharge. When the sewage interception frame 1 is installed, the bottom of the water inlet 2 does not exceed the road 8.
