Description

Technical Field

[0001] This utility model relates to the field of drainage pipe anti-clogging technology, specifically a drainage pipe anti-clogging rain grate. Background Technology

[0002] When rain falls, the storm drain quickly activates its working mode. With its unique mesh structure, it efficiently collects rainwater from the road surface, acting like countless tiny funnels to precisely guide the rainwater into the drainage pipes, preventing road flooding and ensuring the safe passage of pedestrians and vehicles. In addition, the storm drain also has a certain filtering function, intercepting leaves, garbage and other debris to prevent them from entering the drainage pipes and causing blockages, thus reducing the operating efficiency of the drainage system.

[0003] Traditional storm drain grates have many problems in practical use. On roads, storm drain grates allow fine particles such as mud, sand, and pebbles carried by rainwater to accumulate in the drainage pipes, affecting drainage function. When the gaps in the grates are too large, the drainage speed is faster, but debris such as leaves, plastic bags, and branches can easily flow into the drainage pipes, causing blockages, affecting drainage efficiency, and even causing urban flooding. When the gaps are too small, the drainage speed is reduced, and during heavy rainfall, a large amount of rainwater cannot be discharged, also causing road flooding. Furthermore, once debris accumulates on the storm drain grates, cleaning is extremely difficult. Therefore, we need a storm drain grate that prevents blockages in drainage pipes. Summary of the Invention

[0004] The purpose of this utility model is to provide a drainage pipe anti-clogging rain grate to solve the existing problems mentioned in the background art, such as rain grate on the road surface causing fine particles such as mud, sand and small stones carried by rainwater to accumulate in the drainage pipe, affecting the drainage function, and when the gap of the grate is too large, the drainage speed is faster, but debris such as leaves, plastic bags, and branches can easily flow into the drainage pipe and cause blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The fixing plate 206 is located below the rain grate 205 and is fixedly connected to the ductile iron U-shaped groove 1. That is, a fixing plate 206 is fixed at the four corners of the top opening of the ductile iron U-shaped groove 1. The rain grate 205 is supported on the four fixing plates 206. A fastening bolt 207 is installed through the four corners of the rain grate 205. The bottom of the fastening bolt 207 is threadedly connected to the fixing plate 206.

[0024] Furthermore, such as Figure 2 As shown, the ductile iron U-shaped groove 1 forms a rotating structure with the rain grate 205 through the rotating shaft 204. The two ends of the rotating shaft 204 are fixed to the inside of the ductile iron U-shaped groove 1, and the outer wall of the rotating shaft 204 moves with one side of the rain grate 205. With the support of the ductile iron U-shaped groove 1, the rotating shaft 204 can make the rain grate 205 rotate, thereby opening the rain grate 205 and making it easier for workers to clean the inside.

After fine-tuning the flatness and slope, tighten the first nut 203 completely; pass the four fastening bolts 207 through the four corners of the rain grate 205 and connect them to the corresponding fixing plates 206. By rotating the four fastening bolts 207, fix the rain grate 205 on the ductile iron U-shaped groove 1. When it is necessary to open the rain grate 205, the fixation of the rain grate 205 can be released by rotating the four fastening bolts 207, so that the rain grate 205 can be rotated through the rotating shaft 204, thereby opening the rain grate 205. When it is necessary to clean the blockage in the ductile iron U-shaped groove 1, the rain grate 205 can be opened, and the two handles 304 can be lifted upwards. The handles 304 will drive the support block 302 to move upwards, and the support block 302 will drive the cleaning box 303 to move upwards, thus cleaning the blockage inside the cleaning box 303. After cleaning, the cleaning box 303 can be put back into the ductile iron U-shaped groove 1, and the rain grate 205 can be closed.
