[0031] When in use, rainwater falls into the water collection ditch 11, and the water quality detector 12 detects the rainwater in the water collection ditch 11. When the rainwater reaches the discharge standard, the gate 22 in the drainage ditch 21 opens, and the rainwater in the water collection ditch 11 is directly discharged through the drainage ditch 21. When the rainwater does not reach the discharge standard, the gate 22 in the return ditch 31 opens, and the rainwater in the water collection ditch 11 passes through the return ditch 31 into the sewage treatment system, and is discharged after being treated.

[0032] In the utility model, rainwater in the ditch 11 is detected by a water quality detector 12. Rainwater that meets the standards is directly discharged through the drainage ditch 21, and rainwater that does not meet the standards enters the sewage treatment system through the return ditch 31 and is discharged after being treated, thereby improving the cleanliness of rainwater and reducing pollution to the environment.

[0033] To intercept floating objects in rainwater, please refer to Figure 2 In a preferred embodiment, a plurality of cover plates 13 are clamped on the top of the ditch 11 along the length direction of the ditch 11, and the cover plates 13 are provided with leakage holes 14 arranged in an array.

[0034] When in use, on the one hand, the possibility of workers falling into the ditch 11 is reduced, thereby improving safety. On the other hand, rainwater enters the ditch 11 through the leakage hole 14, and the cover plate 13 plays a certain isolation role, thereby reducing the possibility of impurities entering the ditch 11, improving the cleanliness of rainwater, and reducing the burden of subsequent processing.

[0035] To increase the service life of the gate 22, please refer to Figure 3 In a preferred embodiment, the gate 22 includes a door body 24 and a protective layer 25 wrapped around the side of the door body 24.

[0037] In order to facilitate the staff to lift and lower the gate 22, please refer to Figure 3 In a preferred embodiment, handles 27 are fixedly connected to the tops of both sides of the door body 24 .

[0038] When in use, it is convenient for a worker to hold the handle 27 to lift and lower the gate 22, thereby reducing the possibility of slipping.

[0039] In order to intercept floating objects in the drainage ditch 21, please refer to Figure 4 In a preferred embodiment, a grille 4 is installed in the drainage ditch 21.

[0040] When in use, floating objects in rainwater are intercepted, thus improving the cleanliness of rainwater.

[0041] To optimize the grid 4 structure, please refer to Figure 4In a preferred embodiment, the grille 4 includes two cross beams 41 and a plurality of vertical beams 42 disposed between the two cross beams 41 , and the plurality of vertical beams 42 are arranged in sequence and spaced apart along the length direction of the cross beams 41 .

[0042] When in use, the two cross beams 41 play a supporting and fixing role, and the vertical beam 42 plays a role in intercepting floating objects. The structure is simple and the production cost is reduced.

[0043] In order to improve the corrosion resistance of the door body 24, the cross beam 41 and the vertical beam 42, please refer to Figure 4 In a preferred embodiment, the door body 24, the cross beam 41 and the vertical beam 42 are all coated with an anti-corrosion layer, and the material of the anti-corrosion layer is asphalt.

[0044] When used, asphalt has the functions of waterproofing, moisture-proofing and anti-corrosion, and it is low-priced and easy to construct.

[0045] To remove the floating objects between the adjacent vertical beams 42, please refer to Figure 4 In a preferred embodiment, the vertical beam 42 is horizontally rotatably connected to the cross beam 41, and a plurality of pull rods 43 are fixedly connected to the vertical beam 42 at intervals along the length direction of the vertical beam 42. The cross beam 41 is provided with a driving component 5 for driving the vertical beam 42 to rotate.

[0046] When in use, the size of some floating objects may be the same as the spacing between adjacent vertical beams 42, and these floating objects may be stuck between adjacent vertical beams 42, causing certain troubles for subsequent cleaning. Under the driving action of the driving assembly 5, the vertical beams 42 rotate, and the vertical beams 42 drive the pull rod 43 to rotate, and the pull rod 43 pulls out the floating objects stuck between adjacent vertical beams 42, which is convenient for subsequent cleaning.

[0047] To drive the pull rod 43 to rotate, please refer to Figure 5 In a preferred embodiment, the driving assembly 5 includes a motor 51 mounted on the cross beam 41, a worm 52 is fixedly connected to the output shaft of the motor 51, the worm 52 extends along the length direction of the cross beam 41, and a turbine 53 meshing with the worm 52 is coaxially fixedly connected to the top of the plurality of vertical beams 42.

[0048] When in use, the motor 51 is started, the motor 51 drives the worm 52 to rotate, the worm 52 drives multiple turbines to rotate, the turbine drives the vertical beam 42 to rotate, the vertical beam 42 drives the pull rod 43 to rotate, so as to pull out the floating objects between adjacent vertical beams 42. One motor 51 can drive multiple vertical beams 42 to rotate at the same time, which is energy-saving and environmentally friendly and reduces costs.

[0049] To improve the cleaning effect of the pull rod 43, please refer to Figure 4 In a preferred embodiment, the pull rods 43 on adjacent vertical beams 42 are arranged in a staggered manner.

[0050] During use, when the pulling rods 43 are arranged in a staggered manner, the gaps between the pulling rods 43 are smaller, making it easier to pull out floating objects between adjacent vertical beams 42, resulting in a better cleaning effect.
