Description

Technical Field

[0001] The utility model relates to the field of rainwater collection, in particular to a municipal road rainwater collection device. Background Art

[0002] In the construction of municipal roads, rainwater can be collected and treated for use in green irrigation, which can not only reduce drainage pressure but also alleviate the problem of water shortage.

[0003] When collecting rainwater, a rainwater collection device is generally used. After the rainwater collection device is full of rainwater, the rainwater in the rainwater collection device will be pumped out through a pumping device, and then the green belt will be irrigated through a watering equipment, thereby reducing the drainage pressure.

[0004] After searching the patent document with the announcement number CN220847970U, the patent document discloses "a municipal road rainwater collection device, the filter cartridge in the above device can be installed in the sewer, directly replacing the floor drain connecting the sewer and the ground, so a grate is arranged on the upper surface of the filter cartridge to intercept branches or other larger impurities, and the debris accumulated on the grate can be cleaned by sanitation, and a filter plate is also arranged in the filter cartridge, the filter plate is mainly connected to the debris such as leaves that can pass through the grate, the filter plate is tilted, so that the debris accumulated on the filter plate rolls down into the collection basket under the impact of water flow and its own gravity, the collection basket can be cleaned regularly, and the rainwater filtered by the grate and the filter plate basically does not contain larger debris, and then the stone particles in the rainwater are intercepted by the arranged permeable plate, the permeable plate is conical, the rainwater falls on the permeable plate and penetrates to the bottom, and the stone falls on the permeable plate and rolls down and falls out from the top opening of the bundle on the filter cartridge.";

[0005] When the above-mentioned device is in operation, since the above-mentioned device can also be installed in the sewer, when collecting rainwater, it is easy for some debris mixed with sand, gravel, soil and the like to be brought into the collecting device. Although the above-mentioned device can filter some debris such as leaves and stones, some fine sand, gravel and soil are difficult to filter. In this way, when the pumping equipment pumps out the water in the water collection device, it is easy for these unfiltered sand and gravel to be pumped out along with it, which can easily cause these sand and gravel to affect the pumping equipment. In addition, when the rainfall is large, if some larger leaves flow onto the grate of the above-mentioned device with the rainwater, the leaves can easily block the grate, thereby causing a large amount of rainwater to be lost. Utility Model Content

[0006] The purpose of the utility model is to provide a municipal road rainwater collection device in order to solve the above problems.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0008] A municipal road rainwater collection device comprises a bottom plate, a water collection box is fixed on the upper end of the bottom plate, and a filtering mechanism for filtering impurities in the rainwater;

[0009] The filtering mechanism includes a water collecting bucket, which is arranged at the upper end of the water collecting box. Lower extension rods are fixed at the four corners of the lower end of the water collecting bucket, and the lower extension rods are slidably connected to the inner wall of the water collecting box. A filter plate is fixed at the bottom of the water collecting bucket. A sliding frame plate is arranged between the four lower extension rods, and the sliding frame plate is slidably connected to the inner wall of the water collecting box. Two threaded plug rods are arranged at both ends of the sliding frame plate, and the threaded plug rods penetrate the water collecting box and are threadedly connected to the sliding frame plate. A plurality of telescopic rods are fixed to the lower end of the sliding frame plate, and springs are arranged on the periphery of the telescopic rods. A pressure frame is fixed to the lower end of the telescopic rods, and a mounting square ring is fixed to the lower end of the lower extension rod. A metal sand filter frame is fixed to the lower end of the mounting square ring by bolts. The filter mesh size of the metal sand filter frame is 0.2 cm. Two lifting racks are fixed in the middle of the water collecting bucket.

[0010] Preferably, the water collecting bucket is an inverted trapezoidal structure that is wide at the top and narrow at the bottom, and the height of the water collecting bucket is 20 centimeters.

[0011] Preferably, a long strip through groove is provided in the middle of the sliding frame plate and the pressing frame, and the distance between the sliding frame plate and the pressing frame is the same as the height of the installation square ring and the metal sand filter frame.

[0012] Preferably, the edges of the inner wall of the upper end of the installation square ring are rounded.

[0013] Preferably, the size of the pressing frame is smaller than the size of the inner wall of the metal sand filter frame.

[0014] Preferably: a drain pipe is fixed at the bottom of one end of the water collecting box, and a valve body is installed in the middle of the drain pipe.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] When the above-mentioned device collects rainwater, the size of the filter screen of the metal sand filter frame is small. In this way, when rainwater flows into the device with some mud and sand, the metal sand filter frame will filter out the mud and sand in the rainwater. When it is necessary to clean the mud and sand inside the metal sand filter frame, the lifting frame is repeatedly lifted and connected with the water collecting box through the sliding connection of the lower extension rod. When the lifting frame is lifted, the structure of the filter mechanism except the sliding frame plate and the pressure frame can be raised. In this way, when the metal sand filter frame rises, the pressure frame can squeeze the mud and sand in the metal sand filter frame, thereby squeezing out the rainwater remaining in the mud and sand, and then the threaded plug rod is unscrewed, and finally the lifting frame is lifted again to lift the entire filter mechanism, so as to facilitate its cleaning. Moreover, through the setting of the water collecting bucket, when the upper surface of the filter plate is blocked and affects the rainwater entering the device, a certain amount of rainwater can be stored inside the water collecting bucket, thereby avoiding a large amount of rainwater from being directly lost.
