[0002] Urban drainage systems are usually composed of drainage pipes and sewage treatment plants. When the sewage and rainwater diversion system is implemented, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled. Rainwater runoff is collected by drainage pipes and discharged into nearby water bodies. In recent years, heavy rains have occurred frequently in various places, and the drainage systems of many cities cannot drain water in time, resulting in urban waterlogging disasters.

DETAILED DESCRIPTION

[0023] See also Figure 1-4 A drainage structure for municipal engineering includes a main pipe 1. Two drainage pipes 2 are fixedly connected to the outer surface of the main pipe 1. A non-return mechanism 3 is fixedly connected to the inner wall of the main pipe 1. A top cover 4 is arranged inside the main pipe 1. A fixed shaft 5 is fixedly connected to the inner wall of the top cover 4. The outer surface of the fixed shaft 5 is rotatably connected to the inner wall of the main pipe 1. The top cover 4 is provided to support the rolling of pedestrians and vehicles. The fixed shaft 5 allows the top cover 4 to rotate with the main pipe 1 to play a connecting role.

[0024] The anti-return mechanism 3 includes two stop plates 301, and the outer surface of each stop plate 301 is rotatably connected to the inner wall of the drain pipe 2. Two air holes 7 are provided on the upper surface of the top cover 4, and a lifting hole 6 is provided on the upper surface of the top cover 4. The lifting holes 6 make it convenient for the staff to lift up the top cover 4, and the air holes 7 play a role in ventilation.

[0025] The front of each stop plate 301 is fixedly connected with a handle 302, the inner wall of each drain pipe 2 is fixedly connected with a blocking block 303, the inner wall of the main pipeline 1 is fixedly connected with an anti-fall frame 8, and the inner wall of the anti-fall frame 8 is fixedly connected with an anti-fall net 9. The anti-fall frame 8 and the anti-fall net 9 can both play an anti-fall role and can catch people or objects that are about to fall into the main pipeline 1.

[0026] The front of each blocking block 303 is in contact with the back of the stop plate 301, and the inner wall of the main pipe 1 is fixedly connected to the support frame 304. Six bolts 10 are arranged inside the main pipe 1. The end of each bolt 10 close to the anti-fall frame 8 penetrates the anti-fall frame 8 and is threadedly connected to the inner wall of the main pipe 1. The bolts 10 are arranged to fix the anti-fall frame 8, and the anti-fall frame 8 is threadedly fixed to the inner wall of the main pipe 1.

[0027] The inner wall of the support frame 304 is fixedly connected with two limit blocks 305 and two load-bearing blocks 307, the inner wall of the support frame 304 is fixedly connected with four rotating seats 306, the inner wall of the main pipe 1 is fixedly connected with a mud guard 11, the bottom surface of the mud guard 11 is fixedly connected with a mesh plate 12, and the bottom surface of the mesh plate 12 is fixedly connected to the inner bottom wall of the main pipe 1. By providing the cooperation of the mud guard 11 and the mesh plate 12, garbage can be blocked from entering the downstream, thereby playing an anti-blocking role.

[0028] Two water stop plates 308 are arranged inside the support frame 304, and the inner wall of each water stop plate 308 is fixedly connected to two rotating shafts 309, and the outer surface of each rotating shaft 309 is rotatably connected to the inner wall of the rotating seat 306. A limiting edge 13 is arranged below the top cover 4, and the outer surface of the limiting edge 13 is fixedly connected to the inner wall of the main pipeline 1. By setting the limiting edge 13, the load-bearing capacity of the top cover 4 is increased.

[0029] The working principle of the utility model is as follows: when in use, rainwater first enters the interior of the main pipe 1 from the periphery of the top cover 4 or the tilting holes 6 and the air holes 7, and then the rainwater passes through the anti-falling net 9 and falls on the water stop plate 308. At this time, the water stop plate 308 is connected to the interior of the rotating seat 306 by rotating the rotating shaft 309. At this time, the water stop plate 308 will naturally fall under the influence of gravity. At this time, the bearing block 307 can be used to limit the rotation angle of the water stop plate 308, which will not be parallel to the main pipe 1, but will form a certain angle with the main pipe 1;

[0030] If there is a lot of rain at this time, the rainwater left from the upstream will first enter the main pipe 1, and then the rainwater will pass through the mesh plate 12 to intercept the garbage brought down from the upstream and remain inside the main pipe 1. If the rain is too heavy and the drainage end has a backflow phenomenon due to excessive rainwater, the backflow of rainwater will first contact the stop plate 301 inside the downstream drainage pipe 2, and the stop block 303 will be used to block the stop plate 301 until the stop plate 301 completely blocks the inner wall of the drainage pipe 2, making it difficult for water to flow back from the downstream drainage pipe 2 to the upstream main pipe 1;

[0031] If the rain is heavy and enters the main pipe 1 from the top cover 4 of the road surface, a large amount of water will accumulate on the road surface and inside the main pipe 1 when the drainage volume of the pipe is less than the rainfall. If the rain accumulates to the height of the water stop plate 308, the water stop plate 308 is affected by the buoyancy and the constraints of the load-bearing block 307 and the limit block 305. At this time, the water stop plate 308 rotates around the rotation axis 309 as the axis until the water stop plate 308 contacts the limit block 305. At this time, the two water stop plates 308 are both vertical to the main pipe 1. At this time, the water stop plate 308 and the inner wall of the support frame 304 are tightly fitted to effectively play a role of sealing and water stopping. Until the rain recedes, the water stop plate 308 naturally falls due to the influence of gravity and the lack of buoyancy, and then returns to normal drainage use, achieving the drainage structure used in this municipal engineering project, which can effectively solve the problem of excessive rainwater backflow in urban waterlogging.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
