[0004] However, at present, the accumulated water will be recycled through drainage channels. In the early stage of rainfall, the rain first dissolves pollutants such as acidic gases, automobile exhaust, and factory exhaust in the air, and then washes the impermeable surfaces such as roofs and roads after falling to the ground, thus carrying a large amount of pollutants, such as dust, debris, oil, heavy metals and other suspended matter, with a high degree of pollution, even exceeding the pollution level of ordinary urban sewage. Therefore, if the initial rainwater flows directly into the same reservoir, it will increase the difficulty of subsequent sewage treatment. Summary of the invention

[0005] In order to divert and store initial rainwater and reduce the difficulty of subsequent sewage treatment, the present application provides a municipal road rainwater drainage system.

[0007] By adopting the above technical solution, after the initial rainwater mixed with impurities flows into the underground pipe, it will first contact the sieve plate at the bottom, and the impurities will remain on the sieve plate. The initial rainwater will flow into the initial rainwater channel. At the same time, after the absorbent block absorbs the rainwater, as its weight increases, the partition plate and the sieve plate will rotate, so that the rainwater will flow into the later rainwater channel, achieving the purpose of diversion.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment discloses a municipal road rainwater drainage system, referring to Figure 1 , Figure 2 , including an underground pipeline 100 , the cross-section of the underground pipeline 100 is rectangular, the bottom of the underground pipeline 100 is rotatably connected to a sieve plate 110 , and the sieve plate 110 is connected to one side wall of the underground pipeline 100 through a rotating shaft 111 .

[0025] The lower side of the underground pipe 100 is an initial rainwater channel 112, and there is a certain distance between the initial rainwater channel 112 and the sieve plate 110. At the same time, the side of the underground pipe 100 close to the rotating shaft 111 is a later rainwater channel 113, and a receiving box 114 is provided on the side of the underground pipe 100 away from the later rainwater channel 113. The receiving box 114 is located on the lower side of the sieve plate 110.

[0026] The inner wall of the underground pipe 100 near the rotating shaft 111 has a connecting hole 120, and the rotating shaft 111 also has a partition plate 115 perpendicular to the sieve plate 110, and the partition plate 115 is used to block the connecting hole 120. The rainwater that starts to flow in will flow downward along the underground pipe 100, and after passing through the sieve plate 110, it will flow into the initial rainwater channel 112 on the lower side, and the impurities will be intercepted on the sieve plate 110.

[0027] The sieve plate 110 has a water absorbing block 122 for absorbing rainwater on the lower side, and a mounting frame 121 on the lower side of the sieve plate 110. The water absorbing block 122 is made of sponge material in this embodiment, and is embedded and fixed in the mounting frame 121. The water absorbing block 122 is located near the receiving box 114. In this embodiment, there are multiple long holes on the sieve plate 110, and the water absorbing block 122 is located at the farthest side of the long holes away from the rotating shaft 111, so that rainwater from top to bottom can contact the water absorbing block 122, but it will not affect the flow of rainwater.

[0028] Reference Figure 2 , Figure 3An elastic member is provided between the sieve plate 110 and the underground pipe 100. The elastic member is a return spring 123. One end of the return spring 123 is connected to the underground pipe 100, and the other end is connected to the sieve plate 110. In this way, the sieve plate 110 has a tendency to abut against the lower end of the underground pipe 100. As time goes by, the water-absorbing block 122 after absorbing water makes the end of the sieve plate 110 heavier. After overcoming the force of the return spring 123, the sieve plate 110 and the partition plate 115 rotate at the same time. At this time, the back side of the partition plate 115 covering the through hole will be opened and will be impacted by rainwater, thereby helping the partition plate 115 to rotate and abut against the inner wall of the underground pipe 100. At this time, the rainwater flows into the later rainwater channel 113.

[0029] At the same time, the sieve plate 110 has an extension portion 124 extending toward the side away from the rotating shaft 111 to the top of the receiving box 114, so that after the sieve plate 110 is rotated, the impurities located on the upper side of the sieve plate 110 can be transported to the receiving box 114. In order to prevent the impurities from falling from the side into the initial rainwater channel 112 when it is opened, the two sides of the sieve plate 110 have baffle plates 125 parallel to the inner wall of the underground pipe 100, and the baffle plates 125 are in the shape of an arc, so that they can move together during the rotation process.

[0030] Reference Figure 1 , Figure 4 An expansion member 130 is provided on the side wall of the underground pipe 100 and at both ends of the rotating shaft 111. Specifically, the expansion member 130 is located on the side of the rotating shaft 111 away from the screen plate 110, so that when rainwater flows in later, it will contact the expansion member 130. A brake block 131 is provided on the rotating shaft 111. The expansion member 130 expands after absorbing water and contacts the brake block 131 to limit the rotation angle of the rotating shaft 111.

[0031] The material of the expansion member 130 is sponge or wood or modified polyurethane or silicone compound or cross-linked sodium polyacrylate, and it can absorb water and expand, and recover after losing water. In this embodiment, it is silicone compound, and its main function is to expand after being soaked in rainwater, and to recover to its original state in the later waterless process. For example, the corresponding material composition may be: vinyl silicone rubber, PAM, sodium bicarbonate, white carbon black, platinum catalyst.

[0032] Reference Figure 4 , Figure 5The expansion member 130 and the brake block 131 are both arc-shaped. The inner wall of the underground pipe 100 has a connecting shell 132 for embedding the expansion member 130. The connecting shell 132 is open on one side close to the rotating shaft 111. The upper side of the connecting shell 132 has a plurality of penetration holes 133, and the expansion member 130 has corresponding water absorption holes 134. When rainwater enters and flows onto the connecting shell 132 in the later period, it can enter through the penetration holes 133 and contact the expansion member 130. The expansion member 130 will gradually expand, and because it is limited on all sides, the expansion member 130 will approach the brake block 131 in the radial direction, and finally contact the brake block 131, thereby limiting the rotation angle of the rotating shaft 111. So that when the rainwater becomes smaller in the later period and the amount of rainwater is not enough to resist the reset spring 123, the expansion member 130 can be fixed.

[0033] When there is no rain at all for a period of time, the water in the expansion member 130 is lost, the limit of the rotating shaft 111 is lost, and the water in the water absorbing block 122 evaporates, and the reset spring 123 will drive the screen plate 110 to reset. When it rains again, the initial rainwater, impurities, and later rainwater can be repeatedly diverted.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
