Description

Technical Field

[0001] This utility model belongs to the field of road drainage technology, specifically relating to a road drainage structure that prevents blockage. Background Technology

[0002] Road drainage systems include drainage covers, sedimentation tanks, and drainage pipes. Rainwater flows into the sedimentation tank through gaps in the drainage covers, then into the drainage pipes, and finally into rivers and other bodies of water. The drainage covers are placed on the road surface to allow rainwater to pass through while blocking debris such as leaves, preventing excessive debris from clogging the sedimentation tank. However, in practice, because the drainage covers are constantly exposed to the outside environment, on sunny days or other days when drainage is not needed, leaves and other debris can easily cover the surface of the drainage covers, causing blockages in the gaps. This reduces the flow of rainwater through the gaps, making it difficult for rainwater to enter the sedimentation tank during rainy days, thus preventing the proper drainage of water from the road. Utility Model Content

[0020] Please see Figures 1-7The present invention provides the following technical solution: a drainage cover plate 1 is provided, the drainage cover plate 1 has several water leakage slits 11 inside, a scraper rod 2 is slidably connected to the top of the drainage cover plate 1, an auxiliary block 21 is fixedly connected to the bottom of the scraper rod 2, a water guide plate 3 is fixedly connected to the bottom of the drainage cover plate 1, a water inlet chamber 31 is detachably connected to one side of the water guide plate 3, several water delivery pipes 32 are installed at the bottom of the water inlet chamber 31, a settling chamber 4 and a counterweight block 41 are provided below the drainage cover plate 1, the position of the settling chamber 4 corresponds to the position of the water delivery pipes 32, and a traction rope 42 is fixedly connected between the settling chamber 4, the counterweight block 41 and the auxiliary block 21.

[0021] In this implementation scheme: the drainage cover 1 is used to support and connect various components, thereby completing the work of guiding road rainwater into the sedimentation tank through the cooperation of other components, and completing the final drainage work through the drainage pipe. The drainage cover 1 has several drainage slits 11 inside, through which rainwater from the road flows downwards. A water guide plate 3 is fixed to the bottom of the drainage cover 1, guiding the downward-flowing rainwater into the water intake chamber 31. The rainwater entering the water intake chamber 31 is then discharged through the water delivery pipe 32. Since the position of the sedimentation chamber 4 corresponds to the water delivery pipe 32, ... Rainwater discharged through water pipe 32 enters and is stored inside the settling chamber 4. When the settling chamber 4 is empty, its mass is less than that of the counterweight 41. Since both the settling chamber 4 and the counterweight 41 are connected to the auxiliary block 21 via traction rope 42, the counterweight 41 uses its own weight to hold the scraper rod 2 and the settling chamber 4 in a certain position. However, when the settling chamber 4 is full of rainwater, the mass of the settling chamber 4 and the rainwater inside will be greater than that of the counterweight 41. This causes the settling chamber 4 to move vertically downwards by gravity, and the auxiliary block 21 and the counterweight 41 are moved by the traction rope 42. Block 41 moves, and when auxiliary block 21 moves, it drives scraper 2 to move at the top of drainage cover 1. Scraper 2 scrapes away leaves and other debris above drainage cover 1, thus preventing some of the leak gaps 11 from being blocked by leaves and other debris, ensuring the flow of rainwater through the leak gaps 11. When the settling chamber 4 is full of rainwater, the rainwater flowing into the settling chamber 4 through water pipe 32 will overflow and flow downwards into the grit chamber. When the rainwater flows, it will carry sand and other impurities. However, the inner wall of water pipe 32 is small, preventing sand and other impurities from flowing downwards with the rainwater into the settling tank. Inside the sedimentation chamber 4, the amount of sand and gravel impurities reaching the sedimentation tank is reduced, further reducing the possibility of impurities clogging the drainage pipes. The water intake chamber 31 is connected to the water guide plate 3 by bolts, etc., so that the staff can remove the impurities inside the water intake chamber 31 at certain intervals to prevent the impurities from clogging the drainage hole 34. After the rainwater is completely drained, the rainwater inside the sedimentation chamber 4 will gradually evaporate, causing the mass of the sedimentation chamber 4 to gradually fall below the counterweight block 41. Then, the counterweight block 41 will drive the scraper rod 2 and the sedimentation chamber 4 to move back to their original positions through the traction rope 42, waiting for the next operation.

[0022] The top of the drainage cover 1 is provided with a guide groove 12, and the auxiliary block 21 is slidably connected to the inside of the drainage cover 1 through the guide groove 12. The guide groove 12 at the top of the drainage cover 1 is used to guide and constrain the sliding of the scraper rod 2, so that when the settling chamber 4 or the counterweight block 41 drives the scraper rod 2 to move through the traction rope 42, the scraper rod 2 will not deviate or tilt, ensuring that the scraper rod 2 can move stably to complete the scraping of debris above the drainage cover 1.

[0023] The drainage cover 1 has a clearance groove 13 and a force guide groove 14 inside, which are connected to the guide groove 12. The force guide groove 14 inside the drainage cover 1 is used to make room for the traction rope 42 to pass through, and the traction rope 42 can be stably driven by the gravity of the settling chamber 4 and the counterweight 41 to drive the auxiliary block 21 and the scraper rod 2 to complete the scraping of debris above the drainage cover 1.

[0024] A constraint block 22 is fixedly connected to the outer wall of the auxiliary block 21. The constraint block 22 slides inside the relief groove 13. The constraint block 22 fixed to the outer wall of the auxiliary block 21 is used to constrain the auxiliary block 21. The constraint block 22 slides inside the relief groove 13, thereby preventing the scraper rod 2 from detaching from the top of the drainage cover plate 1. This ensures that the scraper rod 2 can stably complete the scraping of debris above the drainage cover plate 1, preventing debris from blocking part of the water leakage seam 11, so as to ensure the flow of rainwater through the water leakage seam 11.

[0025] A water inlet 33 is provided on one side of the water intake chamber 31, and the position of the water inlet 33 corresponds to that of the water guide plate 3. Several drainage holes 34 are provided at the bottom of the water intake chamber 31, and several water drop holes 35 are provided inside the water guide plate 3. The water inlet 33 on one side of the water intake chamber 31 is used to guide the rainwater flowing above the water guide plate 3 into the water intake chamber 31, so that the water intake chamber 31 can pre-filter impurities inside the rainwater to reduce the amount of impurities reaching the sedimentation tank, thereby further reducing the possibility of blockage in the drainage pipe. The drainage holes 34 at the bottom of the water intake chamber 31 are used to drain the rainwater inside the water intake chamber 31. The water is introduced into the water supply pipe 32 so that rainwater can be stably discharged into the sedimentation chamber 4 through the water supply pipe 32, and impurities larger than the diameter of the drainage hole 34 will not reach the sedimentation chamber 4, thus achieving the purpose of pre-filtering impurities. The water guide plate 3 has several drainage holes 35. When the rainwater from the road reaches the surface of the water guide plate 3 through the water leakage seam 11, some of the rainwater will be discharged directly into the sedimentation tank through the drainage holes 35, and the other rainwater will carry impurities to the water intake chamber 31, thereby preventing the rainwater from being difficult to discharge due to excessive rainwater flow or blockage of the drainage hole 34.

[0026] The settling chamber 4 has a water storage cavity 43 inside, and several overflow outlets 44 are provided on one side of the settling chamber 4. The water storage cavity 43 inside the settling chamber 4 is used to store rainwater. When the water storage cavity 43 is full of rainwater, the rainwater will be discharged from the inside of the water storage cavity 43 through the overflow outlets 44, so that the rainwater that has been pre-filtered by the water inlet 31 will flow into the grit chamber, so that the rainwater can be drained through the grit chamber and the drainage pipe.

[0027] The working principle and usage process of this utility model are as follows: Workers can install the drainage cover 1 at a suitable position on the road surface. During rainy weather, rainwater on the road surface will flow downwards through the leak seam 11. The downward-flowing rainwater will reach the top of the guide plate 3. Some rainwater will be directly discharged downwards through the drain hole 35, while other rainwater will carry impurities and flow into the water intake chamber 31 under the guidance of the guide plate 3. The impurities will be filtered into the water intake chamber 31 by the drain hole 34. The rainwater will be discharged into the settling chamber 4 through the drain hole 34 and the water pipe 32. When the settling chamber 4 is full of rainwater, the mass of the settling chamber 4 and the rainwater inside will be higher than the counterweight 41, causing the settling chamber 4 to move vertically downwards by gravity, and the auxiliary force will be driven by the traction rope 42. The auxiliary block 21 and the counterweight block 41 move. When the auxiliary block 21 moves, it will drive the scraper 2 to move at the top of the drainage cover 1. The scraper 2 will scrape away the leaves and other impurities above the drainage cover 1, thereby preventing some of the water leakage gaps 11 from being blocked by leaves and other objects, ensuring the flow of rainwater through the water leakage gaps 11. The rainwater that continues to flow into the settling chamber 4 will overflow from the settling chamber 4 through the overflow outlet 44. The overflowing rainwater will flow into the sedimentation tank and eventually be discharged through the drainage pipe. After the rainwater is completely discharged, the rainwater inside the settling chamber 4 will gradually evaporate, causing the mass of the settling chamber 4 to gradually fall below that of the counterweight block 41. Then, the counterweight block 41 will drive the scraper 2 and the settling chamber 4 to move back to their original positions through the traction rope 42, waiting for the next operation.
