Description

Technical Field

[0001] This invention belongs to the field of green space drainage technology, and in particular relates to an overflow-type filter structure for permeable green spaces and its construction method. Background Technology

[0002] There are two main methods for draining green spaces: underground drainage and open drainage. Underground drainage involves digging underground ditches or laying pipes under the green space to drain accumulated water. This method saves land, maintains the original appearance of the ground, and does not affect traffic. Open drainage is a method of draining water by digging open ditches with a certain slope in green areas where surface runoff is not easily achieved.

[0003] Compared with existing technologies, municipal green spaces use direct rainwater infiltration for drainage. Rainwater on the surface often contains impurities, and buried blind pipes also carry soil during drainage. Soil and impurities can cause blockages in drainage ditches and blind pipes during drainage, affecting the rainwater discharge effect. Summary of the Invention

[0016] A method for constructing an overflow-type filter structure for permeable green spaces includes the following steps:

[0017] Step S1: According to the design drawings, dig the corresponding pits under the green space, bury blind pipes for rainwater infiltration under the green space, and pour water troughs and collection troughs at the water collection points at the edge of the green space. The collection troughs are used to store impurities, and the water troughs are connected to the municipal drainage system.

[0018] Step S2: Insert scraper strips into the water tank and open first guide plates on both sides of the water tank. The first guide plates are flush with the openings. Cast a recycling chamber around the water tank. The recycling chamber is inclined downward and connected to the collection tank. The first guide plate is inclined downward on one side and connected to the recycling chamber. The second guide plate is inclined downward on the other side and connected to the collection tank.

[0019] Step S3: The lower end of the collection tank is connected to the water tank through a return pipe, and a second filter screen is inserted into the inside of the collection tank.

The second filter screen in the collection tank blocks the impurities. The rainwater entering the recovery chamber passes through the second filter screen and flows back into the water tank through the return pipe. The rainwater is then discharged into the municipal drainage system through the water tank.

[0023] 2. Rainwater collected through the underground blind pipes in the green space will pass through a spiral mixing shaft. The rotating spiral mixing shaft has a guiding effect on the rainwater, avoiding blockage caused by soil mixed in the rainwater, keeping the water flow unobstructed, and allowing it to flow smoothly into the collection tank. The second filter screen further separates the soil, and the water will pass through the second filter screen, enter the water tank through the return pipe, and be discharged through the water tank.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-5 An overflow-type filter structure for permeable green spaces includes a water tank 1 and a collection tank 3.

A first guide plate 11 is connected to one opening 13, and a second guide plate 12 is connected to the other opening 13.

[0032] A scraper 9 is provided on the surface of the water tank 1. One end of the scraper 9 is fixedly connected to a pull shaft 10. A baffle box 4 is fixedly installed in the collection tank 3. A connecting frame 16 is slidably provided in the baffle box 4. One end of the connecting frame 16 is connected to the pull shaft 10, and the other end of the connecting frame 16 is connected to a first linkage shaft 19.

[0033] The blind pipe 5 is connected to the collection tank 3 through the water pipe 6. A spiral stirring shaft 15 is rotatably installed inside the water pipe 6. The upper end of the spiral stirring shaft 15 passes through the water pipe 6 and is connected to the first linkage shaft 19. A linkage mechanism is provided at the upper end of the spiral stirring shaft 15. The spiral stirring shaft 15 is connected to the first linkage shaft 19 through the linkage mechanism. The linkage mechanism includes a second linkage shaft 20.

[0034] A base plate 23 is fixedly connected to the inner wall of the partition box 4. A reciprocating mechanism is provided on the base plate 23. The first linkage shaft 19 is connected to the connecting frame 16 through the reciprocating mechanism.

[0035] A second filter screen 14 is fixedly installed at an angle on the inner wall of the collection tank 3. The position where the recovery chamber 2 communicates with the collection tank 3 is located above the second filter screen 14. The position where the return pipe 7 communicates with the collection tank 3 is located below the second filter screen 14. The position where the return pipe 7 communicates with the water tank 1 is located below the first filter screen 8. The collection tank 3 stores impurities, the second filter screen 14 filters rainwater, and the rainwater flows into the water tank 1 through the return pipe 7. The water tank 1 is used for the discharge of filtered rainwater.

[0036] A first turntable 21 is fixedly connected to the upper end of the spiral stirring shaft 15. One end of the second linkage shaft 20 is rotatably connected to the edge of the first turntable 21, and the upper end of the second linkage shaft 20 is rotatably connected to the first linkage shaft 19. As the first linkage shaft 19 moves, it drives the second linkage shaft 20 to move, thereby causing the second linkage shaft 20 to drive the first turntable 21 to rotate. The rotation of the first turntable 21 causes the spiral stirring shaft 15 to rotate. The rotation of the spiral stirring shaft 15 can unclog the blind pipe 5 and the water pipe 6, preventing internal blockages.

[0037] A groove 17 is provided at one end of the connecting frame 16 near the pull shaft 10. A slider 22 is fixedly connected to the end of the pull shaft 10 near the connecting frame 16. The slider 22 passes through the groove 17 and slides within it. When the connecting frame 16 moves back and forth, it can pull the pull shaft 10 to move. The groove 17 is provided to accommodate the displacement of the connecting frame 16 during its reciprocating movement. A limit sleeve is provided on the second guide plate 12, through which the pull shaft 10 passes. The limit sleeve serves to limit the movement, allowing the second guide plate 12 to move smoothly back and forth and ensuring the stability of the movement direction.

[0038] A ring rack 18 is provided inside the connecting frame 16. The reciprocating mechanism includes a gear 24, a second turntable 25, and a third turntable 27. A motor 28 is fixedly connected to the base plate 23. The drive end of the motor 28 is fixedly connected to the third turntable 27. The second turntable 25 is positioned above the third turntable 27. A rotating component 26 is fixedly connected between the edges of the second turntable 25 and the third turntable 27. The end of the first linkage shaft 19 away from the second linkage shaft 20 is rotatably connected to the rotating component 26. A gear 24 is fixedly connected to the second turntable 25, and the gear 24 meshes with the outer surface of the ring rack 18. The motor 28 drives the third turntable 27 to rotate through its drive end. As the third turntable 27 rotates, it drives the rotating component 26 at its edge to move. As the rotating component 26 performs circular motion, it drives the first linkage shaft 19 to perform circular motion as well, thereby driving the spiral stirring shaft 15 to rotate through the linkage mechanism.

[0039] The second turntable 25 is fixedly connected to the gear 24 via a fixed shaft. An annular groove is provided inside the annular rack 18, and the upper end of the fixed shaft slides along the annular groove. The annular groove acts as a limit. When the second turntable 25 moves along the annular groove via the fixed shaft, the gear 24 rotates one end around the annular rack 18, allowing the connecting frame 16 to move back and forth relative to the pull shaft 10. This, in turn, drives the scraper 9 to move back and forth within the water tank 1, achieving a cleaning effect. A sealing cap is snapped onto the upper end of the collection tank 3. The upper surface of the baffle box 4 is pointed, and the cross-section of the baffle box 4 is conical. A grille is snapped onto the upper end of the water tank 1. The conical top allows rainwater to flow smoothly downwards, preventing impurities from accumulating on the surface of the baffle box 4.

[0040] A method for constructing an overflow-type filter structure for permeable green spaces includes the following steps:

[0041] Step S1: According to the design drawings, dig the corresponding pits under the green space, bury the blind pipe 5 for rainwater infiltration under the green space, and pour water trough 1 and collection trough 3 at the water collection point at the edge of the green space. The collection trough 3 is used for storing impurities, and the water trough 1 is connected to the municipal drainage system.

[0042] Step S2: A scraper 9 is attached inside the water tank 1, and a first guide plate 11 is opened on both sides of the water tank 1. The first guide plate 11 is flush with the opening 13. A recycling chamber 2 is cast around the water tank 1. The recycling chamber 2 is inclined downward and communicates with the collection tank 3. The first guide plate 11 is inclined downward on one side of the opening 13 and connected to the recycling chamber 2. The second guide plate 12 is inclined downward on the other side of the opening 13 and communicates with the collection tank 3.

[0043] Step S3: The lower end of the collection tank 3 is connected to the water tank 1 through the return pipe 7, and the second filter screen 14 is inserted into the inside of the collection tank 3. The spiral stirring shaft 15 is rotatably installed in the water pipe 6. The blind pipe 5 is connected to the collection tank 3 through the water pipe 6. The upper end of the spiral stirring shaft 15 is connected to the first linkage shaft 19 through the linkage mechanism. The first linkage shaft 19 is connected to the connecting frame 16 through the reciprocating mechanism. The scraper 9 is slidably set on the surface of the first filter screen 8. The pull shaft 10 at one end of the scraper 9 passes through the opening 13 and is slidably connected to the connecting frame 16.

[0044] Step S4: Cover the first linkage shaft 19 and the connecting frame 16 with the partition box 4. The partition box 4 spans across the collection trough 3 and closes the first linkage shaft 19 and the connecting frame 16 downwards. Fix the base plate 23 on the inner wall of the partition box 4. Fix the motor 28 on the base plate 23. Connect the drive end of the motor 28 to the reciprocating mechanism. Finally, cover and seal the structure with soil. The upper ends of the collection trough 3 and the partition box 4 are flush with the upper surface of the green space. Cover the collection trough 3 with a sealing cover. Install a fence for protection on the upper end of the water tank 1.

[0045] When there is standing water on the green area, the motor 28 is started. The motor 28 drives the third turntable 27 to rotate through the drive end. The edge of the third turntable 27 is connected to the second turntable 25 through the rotating part 26. The rotating part 26 is rotatably connected to the first linkage shaft 19. When the third turntable 27 rotates, it will drive the second turntable 25 to rotate through the rotating part 26. The rotating part 26 drives the first linkage shaft 19 to make a circular motion. The second turntable 25 meshes with the ring rack 18 through the gear 24 connected by the fixed shaft. When the gear 24 rotates with the second turntable 25, the relative position of the motor 28 is stable, and the relative position of the gear 24 will also be stable. Under the action of mutual meshing, the connecting frame 16 will make a circular motion. One end of the connecting frame 16 is slidably connected to the pull shaft 10 through the slider 22. The slide groove 17 adjusts the width change of the circular motion of the connecting frame 16, so that the pull shaft 10 retains the length change of the circular motion of the connecting frame 16, thereby enabling the connecting frame 16 to drive the pull shaft 10 to achieve reciprocating motion.

[0046] The scraper 9, which is fixedly connected to one end of the pull shaft 10, will also slide back and forth accordingly. The scraper 9 scrapes the surface of the first filter screen 8, and the rainwater from the green area flows into the water tank 1. The impurities carried in the rainwater will be blocked by the first filter screen 8, and as the scraper 9 moves back and forth, it will be transported to the openings 13 on both sides. The angle of the recovery chamber 2 is set at an inclination. The impurities enter the recovery chamber 2 along the second guide plate 12 and the first guide plate 11 and then flow downward into the collection tank 3. The second filter screen 14 in the collection tank 3 will block the impurities. The rainwater entering the recovery chamber 2 will pass through the second filter screen 14 and flow back into the water tank 1 through the return pipe 7. The rainwater will be discharged into the municipal drainage system through the water tank 1.

[0047] When the first linkage shaft 19 is in circular motion, it will simultaneously drive the second linkage shaft 20 to also be in circular motion. One end of the second linkage shaft 20 is rotatably connected to the edge of the first turntable 21. The first turntable 21 will rotate due to the traction of the second linkage shaft 20. The rotation of the first turntable 21 drives the spiral stirring shaft 15 to rotate. The spiral stirring shaft 15 is installed inside the water pipe 6. The rainwater collected by seeping down through the underground blind pipe 5 of the green space will pass through the spiral stirring shaft 15. The rotating spiral stirring shaft 15 has a guiding effect on the rainwater, avoiding the problem of blockage caused by mud mixed in the rainwater, keeping the water flow unobstructed, and allowing it to flow smoothly into the collection tank 3. The second filter screen 14 further filters the mud. The water will pass through the second filter screen 14, enter the water tank 1 through the return pipe 7, and be discharged through the water tank 1.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
