Description

Technical Field

[0001] This invention relates to the field of rainwater and sewage separation technology, specifically a municipal rainwater and sewage separation device for sponge cities. Background Technology

[0002] This device is an integrated municipal rainwater and sewage separation equipment developed to meet the needs of sponge city construction. It integrates four core functions: initial rainwater diversion, intelligent switching between rainwater and sewage, rainwater storage and purification, and sewage interception and transportation. It can solve the pain points of traditional separate sewer systems, such as initial rainwater pollution, combined sewer overflow, rainwater resource waste, and easy equipment blockage.

[0003] CN219118312U discloses a rainwater and sewage separation device for sponge cities. The device includes: a separation box; multiple inlet pipes, all mounted on the separation box; a sewage pipe mounted on the separation box; a first solenoid valve mounted on the sewage pipe; a rainwater pipe mounted on the separation box; a second solenoid valve mounted on the rainwater pipe; and an accelerated drainage mechanism located at the bottom of the separation box. This rainwater and sewage separation device for sponge cities has the advantages of water quality monitoring, accelerated drainage, and ease of use.

[0004] During the use of this device, the valve needs to be opened manually when intercepting sewage. In the event of heavy rain, the drainage speed is slow, causing the water level in the device to rise. The lack of continuous cleaning of the filter plate leads to blockage of the water inlet. Therefore, a municipal rainwater and sewage diversion device for sponge cities is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a municipal rainwater and sewage separation device for sponge cities, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a municipal rainwater and sewage separation device for sponge cities, including a tank, an inlet at the rear of the tank, a sewage pipe fixedly connected to the inner wall of the tank, a rainwater pipe fixedly connected to the inner wall of the tank, a float mechanism, a drainage mechanism, and a filter mechanism on the inner wall of the tank. A baffle can block the sewage pipe. At this time, the amount of rainwater in the tank continuously increases. When it increases to a certain amount, the rainwater is discharged through the rainwater pipe, thereby realizing the automatic separation and discharge of rainwater and sewage without manual judgment or electrical signal control. It intercepts sewage entirely based on the actual rainfall, avoids the initial rainwater from polluting natural water bodies, and ensures the resource utilization of clean rainwater, significantly reducing energy consumption and labor costs in long-term operation.

[0007] The float mechanism includes a support rod, a bidirectional telescopic rod, a buoyancy ball, a fixing frame, and a partition. The support rod is fixedly connected to the inner wall of the tank. The bidirectional telescopic rod is rotatably connected to the top of the support rod by a torsion spring. The buoyancy ball is fixedly connected to the top of the bidirectional telescopic rod by a thin rope. The fixing frame is fixedly connected to the inner wall of the tank, and the partition is slidably connected to the inner wall of the fixing frame.

[0008] Preferably, the float mechanism further includes a square box, a first fixing block, an inclined block, and a first elastic telescopic rod. The square box is fixedly connected to the left and right sides of the first fixing frame, the first fixing block is fixedly connected to the circumferential surface of the partition, the inclined block is fixedly connected to the inner wall of the square box, and the first elastic telescopic rod is fixedly connected to the inner wall of the square box.

[0009] Preferably, the bidirectional telescopic rod is rotatably connected to the rear of the partition plate, the partition plate is in contact with the sewage pipe, the partition plate is in contact with the rainwater pipe, the fixed block is in contact with the inclined block, the inclined block is slidably connected to the inner wall of the fixed frame, and the telescopic end of the elastic telescopic rod is fixedly connected to the right side of the inclined block. Due to the spring return action of the elastic telescopic rod, the inclined block squeezes the fixed block. Due to the inclined surface of the inclined block, the fixed block moves down a certain distance and reaches the bottom, thereby closing the sewage pipe. The device can be quickly closed through the partition plate, thereby breaking the balance between the incoming and outgoing rainwater, achieving maximum flow drainage, quickly emptying the water accumulated in the device, reducing the pressure on the municipal pipe network, and alleviating urban flooding from the source.

[0010] Preferably, the drainage mechanism includes a movable frame, a drain pipe, a second fixed frame, a second partition, a second fixed block, an L-shaped rod, a rope, and an arc-shaped plate. The movable frame is slidably connected to the inner wall of the tank, the drain pipe is fixedly connected to the inner wall of the tank, the second fixed frame is fixedly connected to the inner wall of the tank, the second partition is slidably connected to the inner wall of the second fixed frame, the second fixed block is fixedly connected to the circumferential surface of the second partition, the L-shaped rod is disposed at the bottom of the filter mechanism, the rope is fixedly connected to the bottom of the second fixed block, and the arc-shaped plate is slidably connected to the inner wall of the drain pipe.

[0011] Preferably, the drainage mechanism further includes a rotating shaft, a gear, a ratchet, a rack, a pawl, a limiting block, a spiral blade, and an elastic telescopic rod. The rotating shaft is rotatably connected to the top of the arc-shaped plate via a supporting ring. The gear is fixedly connected to the circumferential surface of the rotating shaft. The ratchet is fixedly connected to the circumferential surface of the rotating shaft. The rack is fixedly connected to the left side of the L-shaped rod. The pawl is rotatably connected to the left side of the L-shaped rod via a torsion spring. The limiting block is fixedly connected to the left side of the L-shaped rod. The spiral blade is fixedly connected to the circumferential surface of the rotating shaft. The elastic telescopic rod is fixedly connected to the inner wall of the drainage pipe. During the upward movement of the bidirectional telescopic rod driven by the buoyancy ball, the upward movement of the bidirectional telescopic rod drives the moving frame to move upward. The moving frame contacts the fixed block and causes the fixed block to move upward. The upward movement of the fixed block causes the partition plate to move upward. The upward movement of the partition plate allows the drainage pipe to drain water, instantly increasing the total drainage capacity of the system, breaking the drainage bottleneck under peak rainfall, and quickly reducing the liquid level in the device and pipe network, thus avoiding the risk of flooding from the source.

[0012] Preferably, the movable frame is rotatably connected to the rear of the bidirectional telescopic rod, the second fixed frame is in contact with the drain pipe, the movable frame is in contact with the second fixed block, the rope is fixedly connected to the front of the arc plate, the gear meshes with the rack, the pawl is in contact with the top of the limiting block, the pawl is in contact with the ratchet, and the telescopic end of the second elastic telescopic rod is fixedly connected to the right side of the arc plate, thereby causing the gear to rotate. The rotation of the gear drives the first rotating shaft to rotate, the rotation of the first rotating shaft drives the ratchet to rotate, and the rotation of the first rotating shaft causes the spiral blades to rotate. Due to the limiting effect of the pawl and the limiting block, the spiral blades can only rotate in a certain direction, thereby agitating during drainage, breaking down physical obstructions and flow resistance in the drainage process, improving drainage efficiency and smoothness, while avoiding sludge accumulation and blockage inside the device, and ensuring the long-term stability of the rainwater and sewage separation function.

[0013] Preferably, the filtration mechanism includes a water inlet tank, a first fixed rod, a second rotating shaft, straight blades, a belt, a reciprocating screw, a second fixed rod, a first scraper, a filter plate, and a first inclined trough box. The water inlet tank is fixedly connected to the inner wall of the tank body. The first fixed rod is fixedly connected to the left and right sides of the water inlet tank. The second rotating shaft is rotatably connected to the inner wall of the first fixed rod. The straight blades are fixedly connected to the circumferential surface of the second rotating shaft. The belt drive is connected to the circumferential surface of the second rotating shaft. The reciprocating screw is rotatably connected to the inner wall of the water inlet tank. The second fixed rod is fixedly connected to the inner wall of the water inlet tank. The first scraper is movably connected to the circumferential surface of the reciprocating screw. The filter plate is fixedly connected to the inner wall of the water inlet tank. The first inclined trough box is fixedly connected to the inner wall of the water inlet tank.

[0014] Preferably, the turntable, movable plate, fixed plate, U-shaped plate, inclined groove box two, telescopic scraper, fixed rod three, fixed block three, and slide groove are as follows: the turntable is fixedly connected to the circumferential surface of the rotating shaft two; the movable plate is movably connected to the right side of the turntable; the inclined groove box two is fixedly connected to the inner wall of the tank; the fixed plate is fixedly connected to the left and right sides of the inclined groove box two; the U-shaped plate is fixedly connected to the top of the movable plate; the fixed rod three is fixedly connected to the inner wall of the U-shaped plate; the telescopic scraper is slidably connected to the circumferential surface of the fixed rod three; and the fixed... Block 3 is fixedly connected to the front of the telescopic scraper. The chute is opened on the inner wall of the inclined box 2. Due to the fixing and limiting effect of the fixed rod 2, the scraper 1 moves back and forth on the circumferential surface of the reciprocating screw. The reciprocating movement of the scraper 1 can scrape the impurities on the surface of the filter plate onto the inclined box 1 and slide into the inclined box 2. Scraping away the impurities can instantly open the pores of the filter plate, restore its designed drainage flow, ensure the rapid flood discharge capacity during peak rainfall, avoid the risk of waterlogging from the source, prevent pollutants from escaping into natural water bodies, and at the same time ensure the resource utilization of clean rainwater.

[0015] Preferably, the belt is connected to the circumferential surface of the reciprocating screw, the scraper is slidably connected to the circumferential surface of the fixed rod, the moving plate is slidably connected to the inner wall of the fixed plate, the U-shaped plate is slidably connected to the inner wall of the fixed plate, the L-shaped rod is fixedly connected to the left side of the moving plate, the telescopic scraper is in contact with the inclined box two, and the fixed block three is in contact with the chute. The reciprocating movement of the moving plate drives the U-shaped plate to move, the movement of the U-shaped plate drives the fixed rod three to move, the movement of the fixed rod three drives the telescopic scraper to move, and the movement of the telescopic scraper drives the fixed block three to move. Due to the limiting effect of the chute, the fixed block three moves obliquely upward, thereby pushing the impurities in the inclined box two onto the underground passage, making it easier for workers to clean and preventing the limited volume of the inclined box two from causing impurities to accumulate to overflowing state, resulting in secondary pollution and completely destroying the function of the device in intercepting and holding dirt.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This municipal rainwater and sewage separation device for sponge cities works in concert with a support rod, a bidirectional telescopic rod, a buoyancy ball, a fixed frame, a partition, a square box, a fixed block, an inclined block, and an elastic telescopic rod to automatically separate and discharge rainwater and sewage. It requires no manual judgment or electrical signal control, relying entirely on actual rainfall to intercept and discharge sewage, preventing initial rainwater pollution of natural water bodies while ensuring the resource utilization of clean rainwater. This significantly reduces energy consumption and labor costs during long-term operation. Furthermore, the partition can be quickly closed, breaking the balance between incoming and outgoing rainwater to achieve maximum flow drainage, rapidly emptying accumulated water within the device, reducing pressure on the municipal pipe network, and alleviating urban flooding at its source. 2. This municipal rainwater and sewage separation device for sponge cities works in concert with a movable frame, drainage pipe, two fixed frames, two partitions, two fixed blocks, an L-shaped rod, ropes, an arc-shaped plate, and a rotating shaft. This allows the drainage pipe to open and drain water, instantly increasing the system's total drainage capacity, breaking through drainage bottlenecks during peak rainfall, and rapidly reducing the liquid level inside the device and in the pipe network. This mitigates the risk of flooding at its source. Simultaneously, the spiral blades can only rotate in a specific direction, thus agitating the drainage process, eliminating physical obstructions and flow resistance, improving drainage efficiency and smoothness, and preventing internal blockages, ensuring the long-term stability of the rainwater and sewage separation function. 3. This municipal rainwater and sewage separation device for sponge cities works in concert with an inlet tank, a fixed rod, a rotating shaft, straight blades, a belt, a reciprocating screw, a fixed rod, a scraper, and a filter plate. This allows impurities on the filter plate surface to be scraped onto the inclined trough box and slid into the inclined trough box. Scraping away impurities instantly opens the pores of the filter plate, restoring its drainage flow and ensuring rapid flood discharge during peak rainfall. This mitigates the risk of urban flooding at its source, prevents pollutants from escaping into natural water bodies, and ensures the resource utilization of clean rainwater. Simultaneously, it pushes impurities in the inclined trough box onto underground channels for easy cleaning by staff, preventing the limited capacity of the inclined trough box from causing overflow and secondary pollution, thus completely destroying the device's sewage interception and collection function.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11 One embodiment of the present invention is: a municipal rainwater and sewage separation device for sponge cities, including a tank 1, an inlet 2 at the rear of the tank 1, a sewage pipe 3 fixedly connected to the inner wall of the tank 1, a rainwater pipe 4 fixedly connected to the inner wall of the tank 1, a float mechanism 5 provided on the inner wall of the tank 1, a drainage mechanism 6 provided on the inner wall of the tank 1, and a filter mechanism 7 provided on the inner wall of the tank 1. The float mechanism 5 includes a support rod 501, a bidirectional telescopic rod 502, a buoyancy ball 503, a fixing frame 504, and a partition 505. The support rod 501 is fixedly connected to the inner wall of the tank 1. The bidirectional telescopic rod 502 is rotatably connected to the top of the support rod 501 by a torsion spring. The buoyancy ball 503 is fixedly connected to the top of the bidirectional telescopic rod 502 by a thin rope. The fixing frame 504 is fixedly connected to the inner wall of the tank 1. The partition 505 is slidably connected to the inner wall of the fixing frame 504.

[0021] The float mechanism 5 also includes a square box 506, a fixing block 507, an inclined block 508, and an elastic telescopic rod 509. The square box 506 is fixedly connected to the left and right sides of the fixing frame 504, the fixing block 507 is fixedly connected to the circumferential surface of the partition 505, the inclined block 508 is fixedly connected to the inner wall of the square box 506, and the elastic telescopic rod 509 is fixedly connected to the inner wall of the square box 506. This allows for the automatic separation and discharge of rainwater and sewage without the need for manual judgment or electrical signal control. It achieves sewage interception and discharge entirely based on actual rainfall, avoiding initial rainwater pollution of natural water bodies, while ensuring the resource utilization of clean rainwater, and significantly reducing energy consumption and labor costs during long-term operation.

[0022] The bidirectional telescopic rod 502 is rotatably connected to the rear of the partition 505. The partition 505 is in contact with the sewage pipe 3 and the rainwater pipe 4. The fixed block 507 is in contact with the inclined block 508. The inclined block 508 is slidably connected to the inner wall of the fixed frame 504. The telescopic end of the elastic telescopic rod 509 is fixedly connected to the right side of the inclined block 508. At the same time, it can be quickly closed by the partition 505, thereby breaking the balance between the incoming and outgoing rainwater, achieving maximum flow drainage, quickly emptying the water in the device, reducing the pressure on the municipal pipe network, and alleviating urban flooding from the source.

[0023] The drainage mechanism 6 includes a movable frame 601, a drain pipe 602, a fixed frame 603, a partition 604, a fixing block 605, an L-shaped rod 606, a rope 607, and an arc-shaped plate 608. The movable frame 601 is slidably connected to the inner wall of the tank 1, the drain pipe 602 is fixedly connected to the inner wall of the tank 1, the fixed frame 603 is fixedly connected to the inner wall of the tank 1, the partition 604 is slidably connected to the inner wall of the fixed frame 603, the fixing block 605 is fixedly connected to the circumferential surface of the partition 604, the L-shaped rod 606 is located at the bottom of the filter mechanism 7, the rope 607 is fixedly connected to the bottom of the fixing block 605, and the arc-shaped plate 608 is slidably connected to the inner wall of the drain pipe 602.

[0024] The drainage mechanism 6 also includes a rotating shaft 609, a gear 610, a ratchet 611, a rack 612, a pawl 613, a limiting block 614, a spiral blade 615, and an elastic telescopic rod 616. The rotating shaft 609 is rotatably connected to the top of the arc-shaped plate 608 via a supporting ring. The gear 610 is fixedly connected to the circumferential surface of the rotating shaft 609. The ratchet 611 is fixedly connected to the circumferential surface of the rotating shaft 609. The rack 612 is fixedly connected to the left side of the L-shaped rod 606. The pawl... 613 is rotatably connected to the left side of L-shaped rod 606 via a torsion spring. Limiting block 614 is fixedly connected to the left side of L-shaped rod 606. Spiral blade 615 is fixedly connected to the circumferential surface of rotating shaft 609. Elastic telescopic rod 616 is fixedly connected to the inner wall of drain pipe 602, which allows drain pipe 602 to be opened and drained. This can instantly improve the total drainage capacity of the system, break the drainage bottleneck under peak rainfall, quickly reduce the liquid level in the device and pipe network, and avoid the risk of waterlogging from the source.

[0025] The movable frame 601 is rotatably connected to the rear of the bidirectional telescopic rod 502. The fixed frame 603 contacts the drain pipe 602. The movable frame 601 contacts the fixed block 605. The rope 607 is fixedly connected to the front of the arc plate 608. The gear 610 meshes with the rack 612. The pawl 613 contacts the top of the limit block 614. The pawl 613 contacts the ratchet 611. The telescopic end of the elastic telescopic rod 616 is fixedly connected to the right side of the arc plate 608. At the same time, the spiral blade 615 can only rotate in a certain direction, thereby stirring during drainage, breaking down physical obstructions and flow resistance in the drainage process, improving drainage efficiency and smoothness, and avoiding sludge accumulation and blockage inside the device, ensuring the long-term stability of the rainwater and sewage separation function.

[0026] Working principle: When the device is started, rainwater enters the tank 1 through the inlet 2. When the amount of rainwater in the tank 1 reaches a certain level, the buoyancy ball 503 moves upward due to buoyancy. The upward movement of the buoyancy ball 503 drives the bidirectional telescopic rod 502 to move upward, which in turn drives the partition 505 to move downward. Thus, the partition 505 can block the sewage pipe 3. At this time, the amount of rainwater in the tank 1 continues to increase. When it reaches a certain level, the rainwater is discharged through the rainwater pipe 4, thereby realizing the automatic separation and discharge of rainwater and sewage. No manual judgment or electrical signal control is required. It intercepts sewage based entirely on the actual rainfall, avoiding the initial rainwater pollution of natural water bodies, while ensuring the resource utilization of clean rainwater, and significantly reducing energy consumption and labor costs in long-term operation. During the process of the partition 505 moving down to close the sewage pipe 3, the partition 505 moves down, causing the fixed block 507 to move down. The fixed block 507 moves down and contacts the inclined block 508. At this time, when the rainwater inflow and rainwater outflow reach a balance point, rainwater cannot be recycled. Therefore, when the fixed block 507 moves down and squeezes the inclined block 508, due to the spring return action of the elastic telescopic rod 509, the inclined block 508 squeezes the fixed block 507. Due to the inclined surface of the inclined block 508, the fixed block 507 moves down a certain distance and reaches the bottom, thereby closing the sewage pipe 3. The device can be quickly closed by the partition 505, thereby breaking the balance point between the rainwater inflow and rainwater outflow, achieving maximum flow drainage, quickly emptying the water accumulated in the device, reducing the pressure on the municipal pipe network, and alleviating urban flooding from the source.

[0027] During the process of the buoyancy ball 503 driving the bidirectional telescopic rod 502 to move upward, the bidirectional telescopic rod 502 moves upward, causing the moving frame 601 to move upward. The moving frame 601 moves upward and contacts the fixed block 605, causing the fixed block 605 to move upward. The fixed block 605 moves upward, causing the partition plate 604 to move upward. The partition plate 604 moves upward, which in turn allows the drainage pipe 602 to drain water. This can instantly improve the total drainage capacity of the system, break the drainage bottleneck under the peak of rain and flood, quickly reduce the liquid level in the device and the pipe network, and avoid the risk of waterlogging from the source. As the second fixed block 605 moves upward, it drives the rope 607 upward, which in turn pulls the arc-shaped plate 608 forward. This forward movement of the arc-shaped plate 608 causes the first rotating shaft 609 to move, which in turn moves the gear 610, engaging it with the rack 612. The filter mechanism 7 then drives the L-shaped rod 606 to reciprocate up and down, which in turn drives the moving plate 712 to reciprocate, thus engaging the gear... Gear 610 rotates, which drives rotating shaft 609 to rotate. Rotating shaft 609 drives ratchet 611 to rotate, and rotating shaft 609 drives spiral blade 615 to rotate. Due to the limiting effect of pawl 613 and limiting block 614, spiral blade 615 can only rotate in a certain direction, thereby agitating during drainage, breaking down physical obstructions and flow resistance in the drainage process, improving drainage efficiency and smoothness, and at the same time avoiding sludge accumulation and blockage inside the device, ensuring the long-term stability of rainwater and sewage separation function.

[0028] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the filtration mechanism 7 includes a water inlet tank 701, a first fixing rod 702, a second rotating shaft 703, a straight blade 704, a belt 705, a reciprocating screw 706, a second fixing rod 707, a first scraper 708, a filter plate 709, and a first inclined trough box 710. The water inlet tank 701 is fixedly connected to the inner wall of the tank body 1, the first fixing rod 702 is fixedly connected to the left and right sides of the water inlet tank 701, and the second rotating shaft 703 is rotatably connected to the... The inner wall of the fixed rod 702, the straight blade 704 is fixedly connected to the circumferential surface of the rotating shaft 703, the belt 705 is connected to the circumferential surface of the rotating shaft 703, the reciprocating screw 706 is rotatably connected to the inner wall of the water inlet tank 701, the fixed rod 707 is fixedly connected to the inner wall of the water inlet tank 701, the scraper 708 is movably connected to the circumferential surface of the reciprocating screw 706, the filter plate 709 is fixedly connected to the inner wall of the water inlet tank 701, and the inclined trough box 710 is fixedly connected to the inner wall of the water inlet tank 701.

[0029] The components include a turntable 711, a movable plate 712, a fixed plate 713, a U-shaped plate 714, a second inclined chute box 715, a telescopic scraper 716, a third fixed rod 717, a third fixed block 718, and a chute 719. The turntable 711 is fixedly connected to the circumference of the second rotating shaft 703. The movable plate 712 is movably connected to the right side of the turntable 711. The second inclined chute box 715 is fixedly connected to the inner wall of the tank 1. The fixed plate 713 is fixedly connected to the left and right sides of the second inclined chute box 715. The U-shaped plate 714 is fixedly connected to the top of the movable plate 712. The third fixed rod 717 is fixedly connected to... On the inner wall of the U-shaped plate 714, the telescopic scraper 716 is slidably connected to the circumferential surface of the fixed rod 717, and the fixed block 718 is fixedly connected to the front of the telescopic scraper 716. The chute 719 is opened on the inner wall of the inclined box 715, so that impurities on the surface of the filter plate 709 can be scraped onto the inclined box 710 and slid into the inclined box 715. Scraping away impurities can instantly open up the pores of the filter plate 709, restore its drainage flow, ensure rapid flood discharge capacity during peak rainfall, avoid the risk of waterlogging from the source, prevent pollutants from escaping into natural water bodies, and at the same time ensure the resource utilization of clean rainwater.

[0030] The belt 705 is circumferentially connected to the reciprocating screw 706. The scraper 708 is slidably connected to the circumferential surface of the fixed rod 707. The moving plate 712 is slidably connected to the inner wall of the fixed plate 713. The U-shaped plate 714 is slidably connected to the inner wall of the fixed plate 713. The L-shaped rod 606 is fixedly connected to the left side of the moving plate 712. The telescopic scraper 716 contacts the inclined box 715. The fixed block 718 contacts the chute 719. At the same time, it can push the impurities in the inclined box 715 to the underground passage, which is convenient for the staff to clean. It avoids the limited volume of the inclined box 715 from causing impurities to accumulate to overflowing state, causing secondary pollution and completely destroying the function of the device to intercept and collect dirt.

[0031] Working principle: When rainwater flows into inlet 2, it enters the inlet tank 701 through inlet 2 and then enters the tank 1 through filter plate 709. When the rainwater flows out from filter plate 709, it contacts and impacts the straight blade 704, causing the straight blade 704 to rotate. The rotation of the straight blade 704 drives the second rotating shaft 703 to rotate, which in turn drives the belt 705 to rotate. The belt 705 then drives the reciprocating screw 706 to rotate, which in turn drives the scraper 708 to rotate. As the fixed rod 707 provides a fixed limit, the scraper 708 moves back and forth on the circumferential surface of the reciprocating screw 706. The reciprocating movement of the scraper 708 can scrape impurities on the surface of the filter plate 709 onto the inclined box 710 and slide into the inclined box 715. Scraping away impurities can instantly open up the pores of the filter plate 709, restore its designed drainage flow, ensure rapid flood discharge capacity during peak rainfall, avoid the risk of waterlogging from the source, prevent pollutants from escaping into natural water bodies, and at the same time ensure the resource utilization of clean rainwater. During the rotation of the second rotating shaft 703, the rotation of the second rotating shaft 703 drives the turntable 711 to rotate, and the rotation of the turntable 711 drives the moving plate 712 to rotate. Due to the limiting effect of the fixed plate 713, the moving plate 712 moves up and down back and forth. The back and forth movement of the moving plate 712 drives the L-shaped rod 606 to move up and down back and forth. The back and forth movement of the moving plate 712 drives the U-shaped plate 714 to move. The movement of the U-shaped plate 714 drives the fixed rod 717 to move. The movement of the fixed rod 717 drives the telescopic scraper 716 to move. The movement of the telescopic scraper 716 drives the fixed block 718 to move. Due to the limiting effect of the chute 719, the fixed block 718 moves obliquely upward, which can push the impurities in the inclined chute box 715 onto the underground passage, making it easier for the staff to clean. This avoids the limited volume of the inclined chute box 715 from causing impurities to accumulate to overflowing state, causing secondary pollution and completely destroying the function of the device in intercepting and storing dirt.
