[0004] The initial rainwater pool is used for collecting rainwater in the first 20 minutes, and subsequent rainwater is overflowed into the clean rainwater pipe network through the overflow pipe of the initial rainwater pool. The initial rainwater pool is used for collecting initial rainwater in the production device area and the tank area, and the rainwater contains a small amount of combustible organic matter, most of which is insoluble in water and has a density lower than that of water. The rainwater overflowed into the clean rainwater pipe network will carry the organic matter, pollute the entire clean rainwater pipe network system, and further pollute the environment. The organic matter is flammable material, and accumulation to a certain amount will also bring safety hazards.

[0024] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the present application will be described in detail below in combination with the drawings and preferred embodiments.
[0025] The reference signs in the drawings of the specification include: a water storage tank 1, an end cover 2, a preliminary rainwater pool 3, an overflow pool 4, rainwater 5, a ground 6, a partition plate 7, a concrete layer 8, a water collecting pit 9, a filtering assembly 10, an outer frame 1001, a mounting block 1002, a filter screen 1003, a mounting hole 1004, an inner frame 1005, an overflow pipe 11, a collar 12, and a bolt 13.
[0026] The embodiments are as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4
[0027] A rainwater pipe network overflow port filtering structure includes a water storage tank 1 arranged below a ground 6, a partition plate 7 arranged in the water storage tank 1, a preliminary rainwater pool 3 and an overflow pool 4 arranged on both sides of the partition plate 7 respectively, and an overflow pipe 11 in communication with the overflow pool 4, one end of the overflow pipe 11 is arranged in the bottom of the overflow pool 4, and the other end of the overflow pipe 11 is arranged outside the overflow pool 4 and connected with a suction assembly.
[0028] The connection between the overflow pipe 11 and the bottom of the overflow pool 4 is provided with a filter assembly 10 for preventing debris from blocking the overflow pipe 11 due to excessive suction force of the suction assembly.
[0029] Regarding the setting of the device:
[0030] Firstly, the water storage tank 1 is arranged below the ground 6, so that the rainwater 5 can be collected by falling, and a partition plate 7 is arranged in the water storage tank 1. Based on the arrangement of the partition plate 7, the initial rainwater pool 3 and the overflow pool 4 are formed. The rainwater 5 in the initial rainwater pool 3 can only be collected, and then enters the overflow pool 4, because the rainwater 5 in the initial rainwater pool 3 can be used as standby;
[0031] Regarding the collection of rainwater 5 in the initial rainwater pool 3 and the construction of the water storage tank 1:
[0032] The water storage tank 1 adopts a concrete structure, and the inner wall of the water storage tank 1 is coated with a waterproof coating. The top of the initial rainwater pool 3 is communicated with a rainwater 5 inlet, which is arranged on the ground 6. The rainwater 5 inlet is detachably connected with an end cover 2.
[0033] When the rainfall is too large, the end cover 2 is opened to realize the entry of rainwater 5 into the initial rainwater pool 3. When the capacity of the initial rainwater pool 3 is exceeded, the rainwater 5 overflows the partition plate 7 and enters the overflow pool 4;
[0034] Based on the problem of impurity blockage, the bottom of the overflow pool 4 and the overflow pool 4 itself are improved:
[0035] The bottom of the overflow pool 4 is filled with a concrete layer 8, which adopts C35, mainly to provide arrangement space for the water collecting pit 9. Specifically, the top of the concrete layer 8 is provided with a water collecting pit 9, and the upper surface of the water collecting pit 9 is used for mounting the filter assembly 10. The input end of the overflow pipe 11 is located at the inner bottom of the water collecting pit 9.
[0036] Regarding the water collecting pit 9:
[0037] Since the density of impurities is mostly less than that of water, the input end of the overflow pipe 11 is directly located at the inner bottom of the water collecting pit 9 to avoid the influence of impurities, thereby avoiding the entry of impurities into the overflow pipe 11;
[0038] When the suction force of the suction assembly is too large, impurities will still enter the overflow pipe 11;
[0039] Therefore, the device is provided with a filter assembly 10:
[0040] Specifically:
[0041] The filter assembly 10 comprises an outer frame 1001, an inner frame 1005, a filter screen 1003 arranged between the outer frame 1001 and the inner frame 1005, and a mounting hole 1004 arranged in the inner frame 1005 and detachably connected with the input end of the overflow pipe 11.
[0042] The core is the filter screen 1003, which isolates the impurities with a density greater than water from sinking to the bottom, and prevents the impurities from entering the overflow pipe 11 due to excessive suction force of the suction assembly.
[0043] In order to stably install the filter assembly 10, the outer frame 1001 is provided with a mounting block 1002 arranged on the outer side away from the inner frame 1005.
[0044] The mounting block 1002 is provided with a connecting hole, and a connecting screw is threadedly connected in the connecting hole to stably install the filter assembly 10 on the upper surface of the sump 9.
[0045] In order to stably install the overflow pipe 11, the output end of the overflow pipe 11 is arranged on the mounting hole 1004.
[0046] The inner frame 1005 is uniformly provided with a plurality of fixing holes on the upper surface, the input end of the overflow pipe 11 is fixedly connected with a sleeve ring 12, the sleeve ring 12 is provided with a plurality of latch hole 13 holes corresponding in number and position to the fixing holes, and a latch 13 is connected in the latch hole 13 hole to connect the latch hole 13 hole and the fixing hole.
[0047] The latch 13 connects the latch hole 13 hole and the fixing hole to stably install the output end of the overflow pipe 11.
[0048] After the overflow pipe 11 is installed, the end cover 2 is opened, water storage is started, and then the suction assembly works to perform water suction operation on the overflow pool 4. In this process, due to the sinking arrangement of the overflow pipe 11, the impurities with a density less than water cannot enter the overflow pipe 11, and due to the arrangement of the filter assembly 10, the impurities with a density greater than water cannot enter the overflow pipe 11 under the action of large suction force, so that the overflow pipe 11 is prevented from being blocked.
[0049] The overflow pipe 11 sinking technical measure is adopted to prevent the organic pollutants floating on the water surface from entering the clean rainwater 5 pipe network.
[0050] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make minor changes or modifications to the disclosed technical content, or make equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change or modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the technical solution of the present application.
