[0004] In actual use, the drainage structure used in this type of sponge city is not easy to handle impurities attached to the filter structure, which is relatively inconvenient and needs to be improved. Summary of the invention

[0005] In order to facilitate the cleaning of the filtration area of ​​the sponge city road drainage structure, the present application provides a sponge city road drainage structure.

[0006] The present application provides a sponge city road drainage structure, which adopts the following technical solutions:

[0007] A sponge city road drainage structure comprises a road body, the road body is provided with a drainage cavity, the drainage cavity is provided with a confluence pipe, the confluence pipe is provided with a confluence channel, the confluence channel is provided with a liquid inlet side and a liquid discharge side, the liquid flows in a direction from the liquid inlet side toward the liquid discharge side, a filter plate is provided on the inner wall of the confluence channel, the filter plate slides on the inner wall of the confluence channel, the filter plate is provided with filter holes, the filter holes pass through the filter plate, the confluence pipe is connected with a filter pipe, the filter pipe is located below the confluence pipe and on a side of the filter plate close to the liquid inlet side, the filter pipe is provided with a filter channel, and the filter channel is connected with the confluence channel; the filter plate is connected with a driving member, the driving member drives the filter plate to move in a direction close to the liquid discharge side, the inner wall of the confluence channel is provided with a control member, the control member is connected with a scraper, and the control member drives the scraper to move in a vertical direction.

[0008] By adopting the above technical solution, a scraper and a control component are set, and the scraper is driven to move by the control component to remove impurities attached to the filter plate, thereby facilitating the cleaning of impurities and reducing the impact of impurities on the filtration of the filter plate. Secondly, impurities are collected through the filter channel, which facilitates the subsequent direct guidance of impurities and part of the liquid to the equipment for processing impurities, and facilitates the confluence of liquids with low impurity content in the confluence channel.

[0009] Optionally, the filter plate is connected to a limit spring, and the limit spring is located on the side of the filter plate away from the liquid inlet side. The elastic force of the limit spring limits the movement of the filter plate toward the discharge side. The inner wall of the confluence channel is provided with a detection component 1, and the detection component 1 is located on the side of the filter plate close to the discharge side. The detection component 1 is used to detect the movement of the filter plate and control the operation of the driving component.

[0010] By adopting the above technical solution, a detection member is set, and the movement of the filter plate is detected by the detection member. In actual use, when impurities are attached to the filter holes, the impact of the liquid increases the moving distance of the filter plate. Therefore, the detection member is used to detect that the filter plate moves to the position to be detected. The detection member sends a signal to the driving member and causes the driving member to drive the filter plate to move, thereby facilitating the scraping operation of the impurities in cooperation with the scraper.

[0011] Optionally, the confluence channel is provided with a detection groove, and the detection member includes a pressure sensor, a reset spring and a detection block, the pressure sensor is located at the bottom of the detection groove, the reset spring is located at the end of the pressure sensor away from the bottom of the detection groove, the detection block is located at the end of the reset spring away from the pressure sensor, the detection block protrudes from the inner wall of the confluence channel, and the elastic force of the reset spring limits the detection block from moving toward the direction close to the bottom of the detection groove. The detection block is provided with an inclined surface, which is located at the end of the detection block away from the reset spring, and the inclined surface extends from the direction away from the liquid inlet side to the direction close to the bottom of the detection groove.

[0012] By adopting the above technical solution, a pressure sensor is set. When the liquid normally impacts and moves the filter plate, it is difficult for the filter plate to move to the position of the detection slot; when impurities are attached to the filter plate, the liquid impact increases the moving distance of the filter plate, thereby causing the filter plate to hit the inclined surface. When the filter plate hits the inclined surface, the detection block moves toward the bottom of the detection slot and causes the reset spring to contract, and the pressure sensor is subjected to pressure from the reset spring. At this time, the pressure sensor transmits a signal to the drive member and causes the filter plate to move, thereby facilitating the subsequent cleaning of impurities on the filter plate. In this way, the handling of impurities attached to the filter plate is more convenient.

[0013] Optionally, the driving member includes a driving motor and a driving screw, the driving screw having a round rod segment at one end away from the driving motor, the limiting spring having a cleaning plate connected to one end away from the filter plate, the cleaning plate having a circulation hole, the circulation hole passing through the cleaning plate, the cleaning plate having an extension rod at one end close to the filter plate, the extension rod being used to embed into the filter hole; the cleaning plate is threadedly connected to the driving screw, the filter plate is threadedly connected to the driving screw, when the driving screw rotates to cause the filter plate to move to the round rod segment, the filter plate stops moving, the cleaning plate moves and causes the extension rod to embed into the filter hole.

[0014] By adopting the above technical solution, in actual use, some impurities may enter the filter holes and get stuck in the filter holes. Such impurities are not easy to remove and easily affect the scraping effect of the scraper on the end face of the filter plate. Therefore, a cleaning plate and an extension rod are provided. The extension rod is embedded in the filter holes and the impurities stuck in the filter holes are cleaned, thereby improving the impurity removal effect.

[0015] Optionally, a fixing protrusion is provided on the inner wall of the confluence channel, and the fixing protrusion is located on the side of the round rod segment away from the driving screw. A fixing spring is provided on one end of the fixing protrusion close to the round rod segment, and the elastic force of the fixing spring limits the filter plate from moving to the round rod segment.

[0016] By adopting the above technical solution, a fixed protrusion is provided, and the movement of the filter plate is limited by the fixed protrusion and the fixed spring, so that when the driving motor rotates, the filter plate contacts the fixed spring so that the fixed spring is in a compressed state. When the driving motor stops rotating, the elastic force of the fixed spring and the impact of water cause the filter plate to return to its original position. In this way, impurities can be removed easily.

[0017] Optionally, the extension rod includes a fixed portion and an extension portion, the extension portion is located at an end of the fixed portion away from the cleaning plate, the extension portion is used to embed into the filter hole, the size of the fixed portion is larger than the size of the filter hole, and when the fixed portion contacts the filter plate, the end of the extension portion away from the fixed portion is flush with the end surface of the filter portion away from the fixed portion.

[0018] By adopting the above technical solution, it is arranged that when the fixed part contacts the filter plate, the end of the extension part away from the fixed part is flush with the end face of the filter part away from the fixed part. Through such an arrangement, the situation where the extension part protrudes from the end of the filter part away from the fixed part to affect the scraping of the scraper is reduced, and the low efficiency of impurity removal in the filter hole is reduced, thereby improving the impurity removal effect.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A scraper and a control member are provided, and the scraper is driven by the control member to move so as to remove impurities attached to the filter plate, thereby facilitating the cleaning of impurities and reducing the influence of impurities on the filtration of the filter plate. Secondly, the impurities are collected through the filter channel, which facilitates the subsequent direct guidance of impurities and part of the liquid to the equipment for treating impurities, and facilitates the confluence of the confluence channel for the liquid with low impurity content;

[0021] 2. A pressure sensor is provided. When the liquid normally impacts and causes the filter plate to move, the filter plate is difficult to move to the position of the detection slot; when impurities are attached to the filter plate, the impact of the liquid causes the filter plate to move further, thereby causing the filter plate to contact the inclined surface. When the filter plate contacts the inclined surface, the detection block moves toward the bottom of the detection slot and causes the reset spring to contract. The pressure sensor is subjected to pressure from the reset spring. At this time, the pressure sensor transmits a signal to the drive member and causes the filter plate to move, thereby facilitating the subsequent cleaning of impurities on the filter plate. In this way, the handling of impurities attached to the filter plate is more convenient.

[0022] 3. A fixed protrusion is set to limit the movement of the filter plate through the fixed protrusion and the fixed spring, so that when the drive motor rotates, the filter plate contacts the fixed spring so that the fixed spring is in a compressed state. When the drive motor stops rotating, the elastic force of the fixed spring and the impact of water return the filter plate to its original position. In this way, impurities can be removed easily.
