By setting up the main pipe for drainage, rainwater can seep outward from the first seepage hole on the main pipe body, so that part of the rainwater can seep back into the soil layer, promoting the rapid infiltration of rainwater and the "sponge" water storage function of the soil; the water inlet hole is in the shape of a long strip, and the width of the water inlet hole is 0.5-1.5 cm. The water inlet hole is provided to increase the catchment area as much as possible without reducing the support strength of the upper part of the main pipe body, thereby reducing the possibility of waterlogging.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the seepage holes of the utility model surround the surface of the distribution device, which makes it difficult to cope with the situation where the device is blocked by soil during backseepage, which may lead to reduced adaptability of the device; the utility model is not easy to automatically clean the inside of the device, and the speed at which rainwater flows into the seepage holes may lead to reduced backseepage efficiency and adaptability of the device.

[0005] Therefore, in view of the above problems, a road rainwater infiltration structure is proposed. Utility Model Content

[0022] See also Figure 1-Figure 3 As shown, a road rainwater infiltration structure comprises a shell 1, a block 2 is fixedly connected to the inner wall of the shell 1, a grille 3 is mounted on the surface of the block 2, a connecting pipe 4 is fixedly connected to one side of the shell 1, a sealing sleeve 7 is connected to the inside of the shell 1, a rotating shaft 8 is rotatably arranged inside the sealing sleeve 7, one end of the rotating shaft 8 is rotatably connected to a base 11, the other end of the rotating shaft 8 penetrates the shell 1 and is rotatably connected to one side of a gear set 13, and the other side of the gear set 13 is fixedly connected to the output end of a motor 14;

[0023] Furthermore, the number of the housings 1 is two, and the two housings 1 are fixedly connected to the two ends of the connecting pipe 4;

[0024] During operation, the structural design of the connecting pipe 4 fixedly connected between the two shells 1 improves the back-infiltration effect of the device.

[0025] Furthermore, a plurality of water seepage holes 5 are evenly distributed on the surface of the connecting pipe 4 near the lower side, and crushed stones 6 are arranged on the outer side of the connecting pipe 4;

[0026] During operation, the structural design that the seepage holes 5 are distributed on the lower side of the connecting pipe 4 reduces the possibility of the device being blocked by mud during backseepage. The structural design that gravel blocks 6 are arranged on the outer side of the connecting pipe 4 further reduces the possibility of blockage caused by mud.

[0027] Furthermore, a spiral blade 9 is fixedly connected to the surface of the rotating shaft 8, and the size of the spiral blade 9 matches the size of the connecting pipe 4;

[0028] During operation, the size of the spiral blade 9 is consistent with the size of the connecting pipe 4, so that the rotation of the shaft 8 drives the rainwater inside the connecting pipe 4 to move, thereby improving the back-infiltration effect of the device.

[0029] Furthermore, a support rod 10 is fixedly connected to the inner wall of the housing 1, and a rotating shaft 8 is rotatably connected to the interior of the support rod 10;

[0030] During operation, the support rod 10 is connected to the rotating shaft 8 through internal rotation, so that the support rod 10 has a supporting and limiting effect on the rotating shaft 8, thereby improving the stability of the device.

[0031] Furthermore, a protective strip 12 is fixedly disposed on the inner wall of the housing 1, the top surface of the protective strip 12 is in an arc shape, and the protective strip 12 is disposed directly above the rotating shaft 8;

[0032] During operation, the protective strip 12 is arranged directly above the rotating shaft 8, thereby increasing the protective effect of the device on the rotating shaft 8. The top surface of the protective strip 12 is designed to be in an arc shape, so that falling debris is bounced off on both sides, further improving the protective effect on the rotating shaft 8.

[0033] Working principle: The device is embedded in the ground, and rainwater falls into the shell 1 through the grille 3, and the rainwater is back-seeded through the seepage holes 5 on the bottom of the connecting pipe 4. Since the seepage holes 5 are distributed on the lower side of the connecting pipe 4, and the outer side of the connecting pipe 4 is provided with gravel 6, the possibility of the device being blocked by mud during back-seepage is reduced. At this time, the motor 14 is controlled by an external power supply to rotate forward and reverse periodically, and the motor 14 drives the gear set 13 to rotate the rotating shaft 8, so that the spiral blade 9 rotates inside the connecting pipe 4. Since the size of the spiral blade 9 is consistent with the size of the inner wall of the connecting pipe 4, the spiral blade 9 drives the rainwater inside the shell 1 on one side to flow back and forth in the shell 1 on the other side, and at the same time increases the speed of the rainwater in the connecting pipe 4 flowing to the seepage holes 5. The sealing performance of the device is increased by the sealing sleeve 7, and the support rod 10 on the inner wall of the shell 1 has a supporting and positioning effect on the rotating shaft 8, thereby improving the stability of the device during operation. The protective strip 12 is arranged directly above the rotating shaft 8, and the top surface of the protective strip 12 is an arc-shaped structural design, which increases the protection effect of the device on the rotating shaft 8.
