[0002] The stormwater inlet is the entrance for rainwater to enter the city's underground and is an important facility for collecting ground rainwater. Rainwater from roads, square lawns, and even the roofs of some buildings first flows into the stormwater inlet through grates. As the bottleneck for collecting rainwater runoff in the urban drainage system, it is also the primary channel for urban non-point source pollutants to enter the water environment. It not only drains urban roads, but also replenishes urban water bodies.

When the water level reaches the highest position of the sedimentation structure, it will be filtered by the anti-blocking structure and enter the interior of the drainage pipe. It will first accumulate at the position of the U-shaped pipe section and will not be discharged until the U-shaped pipe section is full of water. The rainwater accumulated at the position of the U-shaped pipe section will completely block and seal the interior of the drainage pipe, so that the two ends of the interior of the drainage structure cannot be connected through the drainage pipe, so that mosquitoes are blocked from entering the interior of the drainage channel through the drainage pipe. At the same time, the water accumulated on the periphery of the surface of the sedimentation structure enters the interior of the water tank through the guide pipe under the filtration of the filter layer for storage, and the excess water will be discharged through the overflow port. The water level of rainwater accumulated at the position of the U-shaped pipe section will lift the piston to block the drain outlet of the water tank, so that the piston can slide along the water level height of the U-shaped pipe section, and then the rainwater in the water tank can replenish the rainwater in the U-shaped pipe section, so that the water level of the U-shaped pipe section will not be too low, so that the water level can ensure the blocking of the drain pipe. Since the drain pipe is located underground, the underground is relatively cool and the temperature is lower than that of the outside world, and the openings at both ends of the drain pipe are not directly connected to the outside world, the air flows slowly, so the evaporation speed of the rainwater stored in the U-shaped drain pipe will be relatively slow, and the amount of rainwater stored in the water tank is greater than the amount stored in the U-shaped pipe of the drain pipe, and the water in the water tank can also be replenished on rainy days, so that it can achieve the ability of continuous endurance, so the water tank can continuously replenish the U-shaped pipe with sufficient water for blocking. This device has the advantages of being easy to solve the problems of mosquito breeding in rainwater wells and pipelines, and easy blockage in curved pipes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the specific implementation process, Figure 1 As shown, the deposition structure 3 also includes a filter layer 32 and a guide tube 33, the filter layer 32 is laid on the periphery of the surface of the base 31, and the guide tube 33 is fixed to the bottom surface of the base 31; the base 31 is convex in shape and is laid on a plane outside the protrusion of the base 31, and the guide tube 33 passes through the bottom surface of the base 31 and is connected with the filter layer 32; the maximum area of the protective plate 42 is larger than the protrusion area of the base 31, and the protective plate 42 can cover the protrusion position of the base 31, and one end of the drain pipe 6 passes through the center position of the base 31, and the screen 43 is vertically fixed to the surface of the base 31 around the top opening of the drain pipe 6 in a hollow ring shape, and the top of the screen 43 is fixed to the bottom surface of the protective plate 42, and there is a support gap for the screen 43 between the protective plate 42 and the base 31.

After passing through the screen 43 to filter out larger debris, the water is discharged into the interior of the drainage channel 23 through the drain pipe 6 for discharge.
[0025] In the specific implementation process, Figure 1 , Figure 3 and Figure 4 As shown, the water storage structure 5 also includes a fixed rod 52, a floating block 53, a piston 56 and a drain port 57.

When the water level returns to a certain height, the buoyancy of the water will push the floating block 53 to slide upward on the side wall of the fixed rod 52, thereby driving the piston 56 to block the drain port 57 of the water tank 54.
[0027] The working principle of the road rainwater inlet connecting pipe provided by the utility model is as follows:
[0028] When in use, the main body 21 is built inside the ground so that the surface of the main body 21 is slightly lower than the height of the bottom surface. Then, the main body 21 structure is divided into two independent spaces from the middle position. The drainage channel 23 is built at the bottom end of the inner part of the main body 21 below the wellhead 24, so that the drainage channel 23 extends outward so that rainwater can be discharged through the drainage channel 23. The drainage pipe 6 is first fixed in the inner space of the main body 21 at the bottom of the water inlet 22, so that the lower end of the drainage pipe 6 passes through the partition wall inside the main body 21, so that the two ends inside the main body 21 can be connected through the drainage pipe 6, and then the water level pipe 51 is connected. The side wall of the U-shaped section of the drainage pipe 6 is connected, and the maximum height of the water level pipe 51 is not higher than the drainage height of the U-shaped pipe section. Then, a water tank 54 is set at the top of the water level pipe 51 at the height of the water level pipe 51, so that the water tank 54 can be connected with the water level pipe 51 through the drainage port 57. At the same time, the fixing rod 52 passes through the center position of the drainage port 57 so that the piston 56 can block the drainage port 57. Then, the top of the water tank 54 is connected with the drainage pipe 6 through the overflow port 55, and then the guide pipe 33 is connected to the top surface of the water tank 54. Then, the base 31 is built at the position of the guide pipe 33, so that the base 31 is centered at the end of the drainage pipe 6 with a higher opening. The center is formed by dividing the upper and lower spaces into two spaces, and the base 31 is formed into a convex shape, the top surface of the base 31 is flush with the top opening of the drain pipe 6, and the guide pipe 33 is connected to the water tank 54 and the space at the upper end of the base 31, and then the filter layer 32 is laid on the outer surface of the base 31, and then the protective plate 42 is fixed on the raised surface of the base 31 through the pillar 41, so that the protective plate 42 covers the top of the drain pipe 6, and then the screen 43 is covered on the periphery of the pillar 41 to protect the opening of the drain pipe 6, and then the water inlet grate 1 is installed at the water inlet 22 to protect the water inlet 22 so that rain After water enters through the water inlet 22, it is blocked by the protective plate 42 and will not enter the interior of the drainage pipe 6. The rainwater is first accumulated on the periphery of the base 31, so that the sand and gravel entering can be precipitated. Part of the water will pass through the filter layer 32 and the guide pipe 33 into the water tank 54 for storage. After the water level rises, the rainwater can be discharged into the drainage channel through the drainage pipe 6. The incoming rainwater will first accumulate at the position of the U-shaped pipe section, and will not be discharged into the drainage channel 23 until the U-shaped pipe section is full of water, so that the rainwater is discharged through the drainage channel 23. This device has the advantage of being easy to solve the problem of mosquitoes breeding inside rainwater wells and pipes, and easy blockage in curved pipes.
[0029] Compared with the related art, the road rainwater inlet connecting pipe provided by the utility model has the following beneficial effects:

First, the water inlet grate 1 is installed on the inner side wall of the water inlet 22, so that when rainwater enters the interior of the main body 21 through the water inlet 22, larger debris can be blocked outside. After the rainwater enters, it will first accumulate on the periphery of the interior of the sedimentation structure 3, and the sand and gravel entering with the rainwater will be precipitated. When the water level reaches the highest position of the sedimentation structure 3, it will be filtered through the anti-blocking structure 4 and enter the interior of the drainage pipe 6. It will first accumulate in the U-shaped pipe section The U-shaped pipe section will be filled with water before it is discharged, and the rainwater accumulated at the U-shaped pipe section will completely block and seal the interior of the drainage pipe 6, so that the two ends of the drainage structure 2 cannot be connected through the drainage pipe 6, so as to prevent mosquitoes from entering the drainage channel 23 through the drainage pipe 6. At the same time, the water accumulated on the periphery of the surface of the sedimentation structure 3 will enter the interior of the water tank 54 through the guide pipe 33 under the filtration of the filter layer 32 for storage, and the excess water will be discharged through the overflow port 55. , and the water level of rainwater accumulated in the U-shaped pipe section will lift the piston 56 to block the drain port 57 of the water tank 54, so that the piston 56 can slide along the water level of the U-shaped pipe section, so that the rainwater in the water tank 54 can replenish the rainwater in the U-shaped pipe section, so that the water level of the U-shaped pipe section will not be too low, so that the water level can ensure the blocking of the drain pipe 6. Since the location of the drain pipe 6 is underground, the underground is relatively cool and the temperature is lower than that of the outside world, and the openings at both ends of the drain pipe 6 are not directly connected to the outside world. The air flows slowly, so the evaporation speed of the rainwater stored in the U-shaped drain pipe 6 will be relatively slow, and the amount of rainwater stored in the water tank 54 is greater than the amount stored in the U-shaped drain pipe 6, and the water in the water tank 54 can be replenished on rainy days, so that it can achieve the ability of continuous endurance. Therefore, the water tank 54 can continuously replenish the U-shaped pipe with sufficient water for sealing. This device has the advantage of being easy to solve the problems of mosquito breeding inside rainwater wells and pipes, and easy blockage in curved pipes.
