[0026] Reference Figure 1-5 The utility model provides a rainwater pump station drainage structure, which mainly includes:

[0027] The main structure 100, such as Figure 1The main structure 100 includes a water collecting tank 101, a water inlet pipe 102 fixedly connected to the top of one side of the water collecting tank 101, and a drain pipe 103 fixedly connected to the bottom of the other side of the water collecting tank 101. A tank cover 104 is fixedly installed on the top of the water collecting tank 101 by bolts. The tank cover 104 is fixed by bolts so that the tank cover 104 can be disassembled, thereby facilitating the cleaning of impurities inside the filter frame 401 at a later time.

[0028] The partition 200, such as Figure 2-3 The partition 200 is fixedly connected to the inside of the water collecting tank 101, and the bottom of the partition 200 is spaced apart from the inner bottom wall of the water collecting tank 101. The purpose of the spacing is to discharge the filtered rainwater through the drain pipe 103. A through groove 201 is provided on the partition 200, and the inner bottom wall of the through groove 201 corresponds to the bottom of the filter screen plate 300. By providing the through groove 201, the filtered impurities can be introduced into the filter frame 401;

[0029] Filter plate 300, such as Figure 2 The filter screen plate 300 is located on the side of the partition plate 200 facing the water inlet pipe 102, and is fixedly connected to the inner wall of the water collection tank 101 by bolts. The filter screen plate 300 is a hollow semi-conical structure, so that the side of the filter screen plate 300 is an inclined surface, and the impurities filtered by the filter screen plate 300 are easily impacted by the water flow and fall into the filter frame 401 through the through groove 201, which is convenient for the centralized collection of impurities, thereby reducing the blockage of the rainwater pumping station caused by the accumulation of impurities in the rainwater pumping station, thereby ensuring the normal drainage operation of the rainwater pumping station;

[0030] The impurity collecting structure 400 is located on a side of the partition plate 200 away from the filter screen plate 300;

[0031] The fixing structure 500 is connected to the water collecting tank 101 , the impurity collecting structure 400 and the partition plate 200 , and is used to fix the impurity collecting structure 400 .

[0032] Specifically, Figure 4 The impurity collection structure 400 includes a filter frame 401, which is located below the through groove 201. The filter frame 401 is embedded in the space formed between the partition 200 and the water collection tank 101. A pair of fixing rods 402 are fixedly connected to the top of the filter frame 401, and a U-shaped frame 403 with an opening downward is fixedly connected to the top of the pair of fixing rods 402.

[0033] like Figure 5The fixing structure 500 includes a support plate 501 movably arranged on the inner bottom wall of the U-shaped frame 403. The filter frame 401 is positioned by the supporting effect of the support plate 501 so that it will not fall to the bottom of the water collecting tank 101. The partition 200 is provided with a snap-fitting groove 202, and one side of the support plate 501 is adapted to snap-fit ​​with the snap-fitting groove 202. Such a connection can improve the stability of the support plate 501, and thus improve the stability of the filter frame 401. The other side of the support plate 501 slides out of the water collecting tank 101 and is fixedly connected with a fixing seat 502. The fixing seat 502 is fixedly connected to the outer wall of the water collecting tank 101 by fastening bolts 503. The fixing seat 502 is fixed by fastening bolts 503, which has the characteristics of easy disassembly and assembly, and is convenient for taking out the filter frame 401 for cleaning later.

[0034] In summary, during the flood season, rainwater enters the water collection tank 101 through the water inlet pipe 102, and impurities in the rainwater are filtered out by the filter mesh plate 300. The filtered impurities fall into the filter frame 401 through the through groove 201 under the impact of rainwater and are collected centrally. The filtered rainwater flows into the drain pipe 103 through the bottom of the partition 200 and is discharged through the drain pipe 103, thereby reducing the blockage of the rainwater pumping station caused by the accumulation of impurities in the rainwater pumping station, thereby ensuring the normal drainage operation of the rainwater pumping station.

[0035] When the flood season is over, remove the bolts on the tank cover 104, open the tank cover 104, and then remove the fastening bolts 503 on the fixing seat 502. After that, the staff pulls the U-shaped frame 403 to move slightly upward, and then pulls the support plate 501 out of the engaging groove 202 and the water collecting tank 101 through the fixing seat 502 to release the positioning effect on the filter frame 401. Then the staff pulls the filter frame 401 upward through the U-shaped frame 403, takes the filter frame 401 out of the water collecting tank 101 and cleans it. The overall operation is simple, and it is convenient to remove impurities in the filter frame 401.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
