Description

Technical Field

[0001] This utility model relates to the field of urban drainage technology, specifically a diversion structure for urban drainage. Background Technology

[0002] Drainage systems are an important infrastructure of modern cities. People need to use water in their daily lives and production activities. Water can become polluted during use and turn into sewage, which needs to be treated and discharged. In addition, urban precipitation has a large runoff volume, which needs to be discharged in a timely manner to avoid the impact of untimely discharge on the city.

[0003] However, the existing urban drainage system is inadequate and cannot effectively divert and discharge wastewater, which may lead to untimely drainage and thus have an impact on the city.

[0004] As disclosed in announcement number CN215829574U, a diversion structure for urban drainage is installed with diversion pipe one and diversion pipe two. When the discharge speed of the main pipeline is insufficient, the water level in the diversion pipe rises. When the water exceeds the corresponding position of the mounting seat one, the water enters the diversion pipe one through the mounting seat one for diversion. When the water still cannot be discharged in time, when the water exceeds the corresponding position of the mounting seat two, the water enters the diversion pipe two through the mounting seat two again for diversion and discharge. This diversion structure can effectively improve the drainage effect of urban drainage.

[0005] However, the filter screen of this device is prone to clogging during use, which affects the drainage effect.

[0006] Therefore, we urgently need to provide a diversion structure for urban drainage. Utility Model Content

[0007] The purpose of this invention is to provide a diversion structure for urban drainage, in order to solve the problem mentioned in the background art that the filter screen is easily clogged during use, thereby affecting the drainage effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a diversion structure for urban drainage, comprising a main pipe, a diversion box, and diversion pipes. The diversion box is installed on the right end of the main pipe via a flange, and multiple diversion pipes are installed on the right side of the diversion box via flanges. An auxiliary device is provided inside the diversion box, including an anti-blocking mechanism, an anti-backflow mechanism, and a buffer mechanism.

[0009] The anti-blocking mechanism is located inside the diversion box, the anti-backflow mechanism is located inside the main pipe, and the buffer mechanism is located inside the diversion box.

[0010] The anti-clogging mechanism includes a top cover, a filter screen, a telescopic component, a connecting plate, a connecting rod, a mounting plate, a housing, a spring, a mounting rod, and a brush plate. The top cover is bolted to the top of the diversion box. The filter screen is installed inside the diversion box. The telescopic component is fixedly installed on the top of the top cover. The connecting plate is fixedly installed on the top of the telescopic component. The connecting rod is fixedly installed at both ends of the bottom of the connecting plate, with its lower end extending into the diversion box. The mounting plate is fixedly installed at the bottom of the two connecting rods. The housing is fixedly installed at both ends of the left side of the mounting plate. One end of the spring is fixedly installed on the inner wall of the housing. The mounting rod is fixedly installed at the other end of the spring and extends through the mounting plate to the outside of the mounting plate. The brush plate is fixedly installed at the right end of the mounting rod.

[0011] Preferably, the brush plate is inclined and fits against the surface of the filter screen. By activating the telescopic component, the connecting plate is pushed to move the connecting rod up and down. When the connecting rod moves, it moves the brush plate up and down. In conjunction with the spring, the mounting rod is pushed to make the brush plate fit against the surface of the filter screen, thereby sweeping away the impurities attached to the surface of the filter screen and improving the drainage effect.

[0012] Preferably, the housing and mounting plate have mounting holes inside, and the diameter of the mounting holes is equal to the diameter of the mounting rod. A sealing gasket is installed at the connection between the mounting rod and the mounting plate, so that the mounting rod moves in a straight line along the mounting hole, avoiding the brush plate from becoming skewed, which would prevent the brush plate from adhering to the surface of the filter screen.

[0013] Preferably, the anti-backflow mechanism includes a flow-limiting block, a sealing block, a sealing ring, a connecting shaft, a pressure plate, and a second spring. The flow-limiting block is fixedly installed on the inner wall of the main pipe, the sealing block is installed inside the main pipe and located at the lower end of the flow-limiting block, the sealing ring is fixedly installed on the top of the sealing block, the connecting shaft is fixedly installed on the top of the sealing block and extends above the flow-limiting block, the pressure plate is fixedly installed on the top of the connecting shaft, and the second spring is fixedly installed between the flow-limiting block and the pressure plate.

[0014] Preferably, the flow-limiting block has a hollow structure with chamfers at both ends. The diameter of the sealing block is larger than the inner diameter of the flow-limiting block, and the pressure plate is smaller than the inner diameter of the main pipe. After water enters the main pipe, the water squeezes the pressure plate, thereby pushing the connecting shaft to move the sealing block downward. At this time, the water can enter the diversion pipe through the flow-limiting block. When the water flows back, the water exerts an upward thrust on the sealing block, thereby causing the sealing block to move the sealing ring upward to seal the flow-limiting block, thus preventing the backflow of water.

[0015] Preferably, the buffer mechanism includes a box body, a damping rod, a damping spring, a limiting plate, and a pressure rod. The box body is fixedly installed on the front and rear sides of the inner wall of the diversion box. The damping rod is fixedly installed on the inner wall of the box body. The damping spring is installed on the outer side of the damping rod. The limiting plate is fixedly installed on the left end of the damping spring and slidably connected inside the box body. The pressure rod is fixedly installed on the left side of the limiting plate and extends to the outer side of the box body.

[0016] Preferably, the left end of the pressure rod is fixedly connected to the right side of the filter screen. The filter screen is V-shaped. After the water flows into the inside of the diversion box, the impact of the water flow is reduced by the V-shaped filter screen. At the same time, the filter screen pushes the pressure rod to squeeze the damping rod and the damping spring, further reducing the impact on the filter screen and improving the service life of the filter screen.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This diversion structure for urban drainage, by setting an anti-clogging mechanism, pushes the connecting plate through the activation of the telescopic component, which drives the connecting rod to move up and down. When the connecting rod moves, it drives the brush plate to move up and down. In conjunction with a spring, it pushes the mounting rod to make the brush plate fit against the surface of the filter screen, thereby sweeping away the impurities attached to the surface of the filter screen and improving the drainage effect.

[0018] 2. This diversion structure for urban drainage, by setting an anti-backflow mechanism, after water enters the main pipe, the water squeezes the pressure plate, thereby pushing the connecting shaft to move the sealing block downward. At this time, the water can enter the diversion pipe through the flow limiting block. When the water flows back, the water generates an upward thrust on the sealing block, thereby causing the sealing block to move the sealing ring upward to seal the flow limiting block, thus preventing the water from flowing back.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Due to the current technology, the filter screen is prone to clogging during use, thus affecting drainage performance. Please refer to [link / reference needed]. Figures 1-6 This embodiment provides a diversion structure for urban drainage, which can remove impurities attached to the surface of a filter screen and improve drainage efficiency. The diversion structure for urban drainage includes a main pipe 1, a diversion box 2, and diversion pipes 3. The diversion box 2 is installed at the right end of the main pipe 1 via a flange, and multiple diversion pipes 3 are installed at the right side of the diversion box 2 via flanges. The diversion box 2 is equipped with auxiliary devices, including an anti-clogging mechanism, an anti-backflow mechanism, and a buffer mechanism.

[0023] The anti-blocking mechanism is located inside the diversion box 2, the anti-backflow mechanism is located inside the main pipe 1, and the buffer mechanism is located inside the diversion box 2.

[0024] The anti-clogging mechanism includes a top cover 401, a filter screen 402, a telescopic component 403, a connecting plate 404, a connecting rod 405, a mounting plate 406, a housing 407, a spring 408, a mounting rod 409, and a brush plate 410. The top cover 401 is bolted to the top of the diversion box 2. The filter screen 402 is installed inside the diversion box 2. The telescopic component 403 is fixedly installed on the top of the top cover 401. The telescopic component 403 is an electric push rod, model SK25H, which has good waterproof performance and can work normally in humid environments. The connecting plate 404 is fixedly installed on the top of the telescopic component 403. The connecting rod 405 is fixedly installed at the bottom front and rear ends of the connecting plate 404, with its lower end extending into the diversion box 2. The mounting plate 406 is fixedly installed at the bottom of the two connecting rods 405. The housing 407 is fixedly installed at the left front and rear ends of the mounting plate 406. The housing 407 and the mounting plate 406 have mounting holes inside, and the diameter of the mounting holes is the same as the diameter of the mounting rod 409. The mounting rod 409 and mounting plate 406 are connected with a sealing gasket, which allows the mounting rod 409 to move linearly along the mounting hole, preventing the brush plate 410 from tilting and thus preventing it from adhering to the surface of the filter screen 402. One end of the spring 408 is fixedly installed on the inner wall of the housing 407, and the mounting rod 409 is fixedly installed on the other end of the spring 408 and extends through the mounting plate 406 to the outside of the mounting plate 406. The brush plate 410 is fixedly installed on the right end of the mounting rod 409. The brush plate 410 is inclined and adheres to the surface of the filter screen 402. By activating the telescopic component 403, the connecting plate 404 is pushed, which drives the connecting rod 405 to move up and down. When the connecting rod 405 moves, it drives the brush plate 410 to move up and down. In conjunction with the spring 408, the mounting rod 409 is pushed, which drives the brush plate 410 to adhere to the surface of the filter screen 402. This allows the brush plate 410 to sweep away impurities adhering to the surface of the filter screen 402 and improve the drainage effect.

[0025] To prevent water backflow and road contamination, this device is equipped with an anti-backflow mechanism. This mechanism includes a flow-limiting block 501, a sealing block 502, a sealing ring 503, a connecting shaft 504, a pressure plate 505, and a spring 506. The flow-limiting block 501 is fixedly installed on the inner wall of the main pipe 1. The sealing block 502 is installed inside the main pipe 1 and located below the flow-limiting block 501. The flow-limiting block 501 has a hollow structure with chamfered edges at both ends. The diameter of the sealing block 502 is larger than the inner diameter of the flow-limiting block 501, and the pressure plate 505 is smaller than the inner diameter of the main pipe 1. After water enters the main pipe 1, the water squeezes the pressure plate 505. The pressure pushes the connecting shaft 504, causing the sealing block 502 to move downward. At this time, water can enter the diversion pipe 3 through the flow limiting block 501. When the water flows back, the water exerts an upward thrust on the sealing block 502, causing the sealing block 502 to move the sealing ring 503 upward to seal the flow limiting block 501, thereby preventing the backflow of water. The sealing ring 503 is fixedly installed on the top of the sealing block 502. The connecting shaft 504 is fixedly installed on the top of the sealing block 502 and extends above the flow limiting block 501. The pressure plate 505 is fixedly installed on the top of the connecting shaft 504. The second spring 506 is fixedly installed between the flow limiting block 501 and the pressure plate 505.

[0026] Example 2: Based on Example 1, please refer to Figures 1-6 To prevent excessive water flow from causing significant impact on the filter screen 402 and damaging it, this device also includes a buffer mechanism. The buffer mechanism comprises a housing 601, a damping rod 602, a damping spring 603, a limiting plate 604, and a pressure rod 605. The housing 601 is fixedly installed on the front and rear sides of the inner wall of the diversion box 2. The damping rod 602 is fixedly installed on the inner wall of the housing 601. The damping spring 603 is installed on the outer side of the damping rod 602. The limiting plate 604 is fixedly installed on the left end of the damping spring 603 and slides... The dynamic connection is inside the box 601. The pressure rod 605 is fixedly installed on the left side of the limiting plate 604 and extends to the outside of the box 601. The left end of the pressure rod 605 is fixedly connected to the right side of the filter screen 402. The filter screen 402 is V-shaped. After the water flows into the inside of the diversion box 2, the impact of the water flow is reduced by the V-shaped filter screen 402. At the same time, the filter screen 402 pushes the pressure rod 605 to squeeze the damping rod 602 and the damping spring 603, further reducing the impact on the filter screen 402 and improving the service life of the filter screen 402.

[0027] During use, after water enters the main pipe 1, the water squeezes the pressure plate 505, thereby pushing the connecting shaft 504 to move the sealing block 502 downward. At this time, the water enters the diversion box 2 through the flow limiting block 501. After entering the diversion box 2, the water impacts the filter screen 402, causing the filter screen 402 to push the pressure rod 605 to squeeze the damping rod 602 and the damping spring 603, reducing the impact on the filter screen 402 and improving its service life. The water filtered by the filter screen 402 is diverted and discharged through the diversion pipe 3. When the filter screen 402 is clogged, the connecting plate 402 is pushed by activating the telescopic component 403. 4. The connecting rod 405 moves up and down, and the brush plate 410 moves up and down when the connecting rod 405 moves. In conjunction with the spring 408, the mounting rod 409 is pushed to make the brush plate 410 fit against the surface of the filter screen 402, so that the brush plate 410 sweeps away the impurities attached to the surface of the filter screen 402 and avoids the filter screen 402 from clogging. When it is necessary to clean the impurities inside the diversion box 2, the top cover 401 can be removed and cleaned. When water flows back, the water exerts an upward thrust on the sealing block 502, so that the sealing block 502 drives the sealing ring 503 to move up and seal the flow limiting block 501, thereby preventing the backflow of water.
