Technical Field
[0001] The utility model relates to the technical field of drainage engineering, in particular to a self-cleaning rainwater outlet. Background Art
[0002] A rainwater inlet is a structure that collects rainwater on a rainwater pipe or combined pipe. Rainwater on the street surface first flows into the drainage pipe through the rainwater inlet through the connecting pipe. The form, number and arrangement of the rainwater inlet should be determined according to the number of catchment areas, the drainage capacity of the rainwater inlet and the road form. The location of the rainwater inlet should ensure the rapid and effective collection of ground rainwater.
[0003] A grating plate is usually provided on the rainwater outlet to prevent pedestrians and large foreign objects from falling in and to prevent the diversion of rainwater. However, the grating holes on the grating plate are usually large. For rainwater outlets located on streets and other places, there are many pedestrians. Smaller items on pedestrians, such as keys and mobile phones, will fall directly into the rainwater outlet channel after accidentally falling into the rainwater outlet. The grating plate cannot filter smaller foreign objects such as leaves, and the cleaning of the overflow well of the rainwater outlet is also very complicated and difficult. Utility Model Content
[0004] The utility model provides a self-cleaning gully, which overcomes the deficiencies of the prior art and can effectively solve the problem that the grating plates arranged in the existing gully cannot filter smaller impurities and debris, resulting in heavy and difficult cleaning work of the gully overflow well.
[0005] In order to solve the above problems, the utility model describes a self-cleaning rainwater inlet, including an overflow well, an overflow well cushion base, a grille rain grate, a filter screen, a slag discharge pipe, an overflow pipe, and a net cleaning thorn. The overflow well cushion base is fixed at the bottom of the overflow well, a filter screen is provided on the middle and lower side of the overflow well, a spring pull bolt is provided at the connection between the filter screen and the overflow well, and net cleaning thorns corresponding to the mesh holes of the filter screen are provided above the overflow well cushion base below the filter screen, a slag discharge pipe is fixedly connected to the side wall of the overflow well above the filter screen, an overflow pipe is fixedly connected to the side wall of the overflow well below the filter screen, and a grille rain grate is provided at the opening above the overflow well.
[0006] Plastic turf is arranged above the overflow well and around the grille rain grate.
[0007] A layer of bagged gravel is arranged outside the overflow well above the above-mentioned slag discharge pipe, and a plurality of drainage holes penetrating inside and outside are arranged on the overflow well corresponding to the position of the bagged gravel.
[0008] The utility model discloses to filter rainwater entering the overflow well by setting a filter net, filters smaller impurities and debris brought in by the rainwater, and discharges them through a slag discharge pipe. The filtered rainwater is discharged through the overflow pipe, which is convenient for cleaning the overflow well. The utility model solves the problem that the grid plate set at the existing rainwater outlet cannot filter smaller impurities and debris, making the cleaning work of the overflow well of the rainwater outlet heavy and difficult, and achieves the effect of filtering the rainwater in the overflow well.

[0015] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.
[0016] The present invention is further described below in conjunction with the embodiments and drawings:
[0017] like Figure 1-4 As shown, a self-cleaning rainwater inlet comprises an overflow well 1, an overflow well cushion base 2, a grille rain grate 3, a filter screen 7, a slag discharge pipe 9, an overflow pipe 10, and a net-cleaning thorn 11. The overflow well cushion base 2 is fixed to the bottom of the overflow well 1, a filter screen 7 is provided at the middle and lower side of the overflow well 1, a spring pull bolt 8 is provided at the connection between the filter screen 7 and the overflow well 1, and net-cleaning thorns 11 corresponding to the mesh holes of the filter screen 7 are provided above the overflow well cushion base 2 below the filter screen 7, a slag discharge pipe 9 is fixedly connected to the side wall of the overflow well 1 above the filter screen 7, an overflow pipe 10 is fixedly connected to the side wall of the overflow well 1 below the filter screen 7, and a grille rain grate 3 is provided at the opening above the overflow well 1.
[0018] The overflow well 1 is composed of cement mortar brick masonry, the overflow well cushion base 2 is cast by concrete, and the grille rain grate 3 adopts a finished polymer resin composite annular grille rain grate 3. The grille rain grate 3 is 2 to 5 cm lower than the ground at its location and is used for preliminary filtering of rainwater so that rainwater can quickly enter the overflow well 1.
[0019] The spring pull bolt 8 is arranged to ensure that the filter screen 7 has sufficient elastic deformation; the cleaning thorns 11 are arranged one by one corresponding to the mesh holes of the filter screen 7 and are used to clean the blocked mesh holes of the filter screen 7, thereby solving the problem that conventional rainwater outlets are easily blocked and have poor drainage effect.
[0020] The above-mentioned slag discharge pipe 9 and overflow pipe 10 can be set with a certain slope outward to facilitate slag discharge and water drainage; the slag discharge pipe 9 is mainly used to discharge the debris and part of the rainwater filtered out by the filter screen 7.
[0021] like Figure 1 , 3 As shown, plastic turf 4 is provided above the overflow well 1 and around the grille rain grate 3. Thus, rainwater can be prevented from being lost, rainwater can flow smoothly into the overflow well 1, and rainwater splashing can be prevented.
[0022] like Figure 1 , 2 As shown, a layer of bagged gravel 5 is arranged outside the overflow well 1 above the slag discharge pipe 9, and a plurality of drainage holes 6 are arranged on the overflow well 1 corresponding to the position of the bagged gravel 5. The drainage holes 6 can be arranged in a plum blossom shape to facilitate the infiltration of external water.
[0023] When the utility model is in use, the overflow pipe 10 is connected to the nearest rainwater inlet or rainwater well, and the rainwater enters the inner side of the overflow well 1 after preliminary filtration through the grille rain grate 3, and the filter residue is intercepted by the filter screen 7 inside the overflow well 1, and the rainwater flows into the overflow well 1 below the filter screen 7 through the filter screen 7, and then is discharged through the overflow pipe 10. In this process, the accumulation of filter residue will cause the filter screen 7 to be blocked, but as the filter residue on the upper side of the filter screen 7 increases, the filter screen 7 sinks under the action of gravity, and each mesh of the filter screen 7 is aligned with the clean filter at the corresponding position. The net thorns 11 come into contact with each other, and the net cleaning thorns 11 enter the mesh holes to clear and dredge the filter residue in the mesh holes. In this process, a large amount of debris will be suspended on the water surface and instantly washed into the slag discharge pipe 9 by rainwater and discharged from the overflow well 1. As the debris and rainwater are continuously discharged, the weight of the filter screen 7 is reduced, so that it automatically returns to its original position and continues to play the filtering function, thereby achieving the effect of smoothly discharging the rainwater in the overflow well 1; at the same time, during operation, the water outside the overflow well 1 infiltrates through the bagged gravel 5, and then enters the inside of the overflow well 1 through the drainage hole 6 and is then discharged.
[0024] In summary, the utility model filters the rainwater entering the overflow well 1 by setting a filter net 7, filters the smaller impurities and debris brought in by the rainwater, and discharges them through the slag discharge pipe 9. The filtered rainwater is discharged through the overflow pipe 10, which is convenient for cleaning the overflow well 1. It solves the problem that the grid plate set at the existing rainwater outlet cannot filter smaller impurities and debris, resulting in heavy and difficult cleaning work of the rainwater outlet overflow well 1, and achieves the effect of filtering the rainwater in the overflow well 1.
