Description

Technical Field

[0001] The utility model relates to the technical field of drainage, and particularly relates to a rainwater inlet for preventing blockage. Background Art

[0002] Rainwater inlets are an important part of the urban drainage system and occupy an important position in the urban drainage system. They are distributed widely with many points. They not only undertake the function of collecting and discharging surface rainwater in urban areas, but also, because road pollutants will enter the urban water circulation system through the rainwater inlets along with surface runoff, it has become increasingly important to reasonably control water pollutants with the help of rainwater inlets.

[0003] Especially under harsh weather conditions such as heavy rain or rainstorm, the surface runoff is large and contains a large amount of debris, which is likely to cause blockage of the rainwater outlet of the rainwater inlet, resulting in poor water passage in the area and seriously affecting its normal use. Most of the existing rainwater wells are concrete pipe wells. When the well depth is too long, it is necessary to go down into the well for cleaning. During rain, only the form of garbage fishing can be used for garbage cleaning. The cleaning is laborious and the outlet cannot be cleared in time.

[0004] Although the prior art such as CN220318733U discloses a device for preventing blockage of rainwater inlets, its filter tank is square with a small water passing area. When encountering heavy rain, it is easy to cause blockage of the rainwater inlet, poor drainage, and the rainwater inlet loses its function. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above problems and provide a rainwater inlet for preventing blockage. To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rainwater inlet for preventing blockage, comprising a rainwater inlet, a water inlet grate, and a filter tank. The water inlet grate is arranged on the top of the rainwater inlet, and the filter tank is arranged inside the rainwater inlet;

[0007] The filter tank comprises a plurality of filter troughs. Each filter trough comprises an inclined plate, a vertical plate, and a bottom-sealed flat plate. The two side surfaces of the filter trough are provided with inclined plates inclined from the bottom to the center of the filter trough. The front and back surfaces of the filter trough are provided with vertical plates. The bottom of the filter trough is provided with a bottom-sealed flat plate. The inclined plates, vertical plates, and flat plates are uniformly provided with water-permeable holes.

[0008] The filter tank is divided into a plurality of filter troughs. Each filter trough consists of an inclined plate, a vertical plate, and a bottom-sealed flat plate. Compared with the ordinary square filter trough, the total number of water-permeable holes is greatly increased, and the water passing area of rainwater is increased. When encountering heavy rain, some of the water-permeable holes are often blocked. For the ordinary square filter trough, due to the small total number of water-permeable holes, blocking a part of the water-permeable holes will greatly reduce the rainwater interception capacity and is extremely easy to be blocked. The filter tank of the utility model is divided into a plurality of filter troughs, and the total number of water-permeable holes is large. Blocking a part of the water-permeable holes will not greatly affect the interception capacity, and the anti-blocking effect is good.

[0009] As an improvement, the outer vertical plate and the outer inclined plate of the filter box extend upward, and a first protrusion is provided at the top of the outer inclined plate. The upward extension of the outer vertical plate and the outer inclined plate will increase the volume of the filter box, and more intercepted substances can be accommodated in the filter box.

[0010] As an improvement, a second protrusion for placing the inlet grille is provided on the top side wall of the rainwater inlet, and a third protrusion for placing the first protrusion is provided on the inner side wall of the rainwater inlet.

[0011] As an improvement, a handle is provided on the top of the first protrusion.

[0012] As an improvement, a coarse grille is provided on the inlet grille, and a handle hole is provided at the edge of the inlet grille.

[0013] The advantages of the present utility model are as follows:

[0014] 1. The filter box of the rainwater inlet of the present utility model is divided into several filter grooves, the water passing area of the rainwater is increased, and the total number of permeable holes is large, greatly improving the anti-blocking ability of the rainwater inlet.

[0015] 2. The present utility model is provided with a handle and a handle hole. When cleaning, the relevant staff can easily lift the inlet grille and the filter box, and the dredging of the rainwater inlet can be completed only by cleaning the inlet grille and the filter box, without the need to go down the well to clean the garbage, reducing the workload and improving the work efficiency.

[0016] 3. The structure of the present utility model is simple and easy to use, and it can be applied to various types of rainwater drainage systems, with a wide market prospect. Description of the Drawings

[0031] Example 1

[0032] This example discloses a rainwater inlet that prevents blockage.

[0033] As Figure 1 、 Figure 2 、 Figure 3 shown, this example includes a rainwater inlet 1, a grating 2, and a filter box 3. The grating 2 is arranged on the top of the rainwater inlet 1, and the filter box 3 is arranged inside the rainwater inlet 1;

[0034] The filter box 3 includes a number of filter slots 31. The filter slot 31 includes an inclined plate 32, a vertical plate 33, and a bottom-sealed flat plate 34. The two side surfaces of the filter slot 31 are provided with inclined plates 32 that incline from the bottom to the center of the filter slot 31. The front and back surfaces of the filter slot 31 are provided with vertical plates 33, and the bottom of the filter slot 31 is provided with a bottom-sealed flat plate 34. The inclined plate 32, the vertical plate 33, and the flat plate are evenly provided with water-permeable holes 35.

[0035] The filter box 3 is divided into a number of filter slots 31. Each filter slot 31 consists of an inclined plate 32, a vertical plate 33, and a bottom-sealed flat plate 34. Compared with the ordinary square filter slot 31, the total number of water-permeable holes 35 is greatly increased, and the water-passing area of rainwater is increased. When encountering heavy rain, some of the water-permeable holes 35 are often blocked. For the ordinary square filter slot 31, since the total number of water-permeable holes 35 is small, blocking a part of the water-permeable holes 35 will greatly reduce the rainwater interception capacity and is extremely easy to be blocked. The filter box 3 of the present utility model is divided into a number of filter slots 31, and the total number of water-permeable holes 35 is large. Blocking a part of the water-permeable holes 35 will not significantly affect the interception capacity, and the anti-blocking effect is good.

[0036] The outer vertical plate 36 and the outer inclined plate 37 of the filter box 3 extend upward, and a first protrusion 11 is provided at the top of the outer inclined plate 37. The upward extension of the outer vertical plate 36 and the outer inclined plate 37 will increase the volume of the filter box 3, and more intercepted substances can be accommodated inside the filter box 3. The first protrusion 11 can place the filter box 3 on the inner wall of the rainwater inlet 1.

[0037] The top side wall of the rainwater inlet 1 is provided with a second protrusion 12 for placing the grating 2, and the inner side wall of the rainwater inlet 1 is provided with a third protrusion 13 for placing the first protrusion 11. The grating 2 is placed on the top of the rainwater inlet 1 through the second protrusion 12, and the size specification of the grating 2 is adapted to the top opening of the rainwater inlet 1, so that the grating 2 can be effectively fixed. The function of the third protrusion 13 provided on the inner side wall of the rainwater inlet 1 is to place the filter box 3.

[0038] A handle 14 is provided at the top of the first protrusion 11. The handle 14 facilitates the cleaning worker to lift the filter box 3. The worker can regularly clean the garbage intercepted inside the filter box 3. Just cleaning the grating 2 and the filter box 3 can complete the dredging of the rainwater inlet 1, without the need to clean the garbage in the well, reducing the workload and improving the work efficiency.

[0039] The inlet grille 2 is provided with a coarse grille 21, and a lifting hole 22 is provided at the edge of the inlet grille 2. The function of the coarse grille 21 is to intercept larger garbage and prevent the excessive garbage from blocking the rainwater inlet 1. The lifting hole 22 facilitates the cleaning worker to lift the inlet grille 2. After lifting the inlet grille 2, the worker can regularly clean the garbage intercepted inside the filter box 3. Just cleaning the inlet grille 2 and the filter box 3 can complete the dredging of the rainwater inlet 1, without the need to go down into the well to clean the garbage, reducing the workload and improving the work efficiency.
