Description

Technical Field

[0001] The present invention relates to the technical field of sewage interception hanging baskets, and specifically to a water storage collector for sponge city green spaces. Background Art

[0002] A sponge city is a new urban rainwater management concept, with the core of building "sponge bodies" with functions of natural accumulation, natural infiltration, and natural purification, aiming to improve the efficiency of the urban drainage system, reduce urban waterlogging, supplement groundwater, and improve the urban ecological environment. Rainwater converges from areas such as roofs, roads, squares, and green belts to the water inlet through the ground slope, permeable pavement, or drainage pipe network, and enters the PP module water storage tank through the central sewage interception hanging basket device and the flow diversion and filtration device of the pretreatment module. After being filtered and disinfected by the buried integrated machine, the rainwater enters the PP module clean water tank to realize the daily use of water resources, such as watering flowers, washing cars, and flushing toilets. The sewage interception hanging basket device consists of a water inlet, a water outlet, a vertical plate filter box hanging basket.

[0003] For example, a sewage interception hanging basket device for a sponge city rainwater recycling system disclosed in the patent with the patent publication number CN214574505U includes a housing, a cover located at the top of the housing, a water inlet located on the left side of the housing, a water outlet located on the right side of the housing, and further includes a hanging basket located inside the housing, a first fixing ring fixedly connected to the top of the hanging basket, a filter screen located inside the hanging basket and dividing the hanging basket into a first space and a second space, a second fixing ring fixedly connected to the top of the filter screen, and a buckle mechanism for detachably connecting the first fixing ring and the second fixing ring.

[0004] Although the above device solves the problem of convenient disassembly of the filter screen, there are still the following defects: when rainwater enters through the filter barrel of the sewage interception hanging basket device and passes through the filter screen, impurities such as filter cakes formed by the accumulation of fine branches or catkins agglomerates often accumulate in the lower area of the outer surface of the filter screen. However, the filter barrel has a certain depth, which makes it particularly inconvenient to clean the impurities in the lower position of the outer surface of the filter screen. The current method is usually to remove the entire filter screen for cleaning. However, this method is not only laborious, but also the rainwater filtration operation cannot be performed during the removal of the filter screen, thereby affecting the continuity and efficiency of the filtration work. Summary of the Invention

[0005] The present invention aims to solve the above problems, and thus provides a water storage collector for sponge city green spaces.

[0006] The technical solution adopted by the present invention to solve the above problems is: A sponge city green space water storage collector, comprising a rainwater diversion well. The inlet pipe of the rainwater diversion well enters the interior through ground water inflow. The outlet pipe of the rainwater diversion well is communicated with a sewage interception hanging basket device. The outlet pipe of the sewage interception hanging basket device is communicated with a rainwater runoff device. The outlet pipe of the rainwater runoff device is communicated with a PP module water storage tank. The outlet pipe of the PP module water storage tank is communicated with an underground integrated machine. The outlet pipe of the underground integrated machine is communicated with a PP module clean water tank. The sewage interception hanging basket device includes a filter barrel, an inlet pipe communicated with the left side of the filter barrel, an outlet pipe communicated with the right side of the filter barrel, and a thickening plate fixedly connected to the inner wall of the right side of the filter barrel. A through hole is opened in the middle of the thickening plate, and the through hole is communicated with the inlet pipe and the outlet pipe. A spherical filter screen for blocking impurities in water is arranged in the through hole. The middle of the spherical filter screen is rotationally connected to the thickening plate through a second rotating shaft.

[0007] Furthermore, a cavity is opened in the thickening plate. One end of the second rotating shaft extends into the cavity and is fixedly connected to the central shaft of a runner in the cavity.

[0008] Furthermore, an impeller is arranged in the outlet pipe. The impeller is rotationally connected to the inner wall of the outlet pipe through a first rotating shaft. One end of the first rotating shaft penetrates through the outlet pipe and is fixedly connected to the central shaft of a pulley inside an installation box. A transmission belt is sleeved on the pulley, and the end of the transmission belt away from the pulley is sleeved on the runner.

[0009] Furthermore, an arc-shaped extrusion plate is arranged above the spherical filter screen. The top surface of the arc-shaped extrusion plate is fixedly connected to the bottom end of a lifting plate. The lifting plate is slidably connected to the thickening plate. The top end of the lifting plate is fixedly connected to one end of a support rod. The other end of the support rod is fixedly connected to an L-shaped connecting rod. The horizontal bar of the L-shaped connecting rod passes through a strip-shaped through hole opened in the filter barrel. The vertical bar of the L-shaped connecting rod is slidably connected to the installation box. A plurality of positioning holes are opened in the vertical bar. An installation plate is fixedly connected to the top of the installation box, and a tightening bolt that can be inserted into the positioning hole is installed on the outer wall of the installation plate.

[0010] Furthermore, the outlet pipe includes an upper water outlet channel and a lower water outlet channel. The upper water outlet channel is communicated with the through hole of the thickening plate, and the lower water outlet channel is not communicated with the through hole of the thickening plate. An inlet for communicating with the lower water outlet channel is opened at one end of the upper water outlet channel close to the spherical filter screen. Further, a blocking plate for blocking the water inlet is arranged at the top of the lower water outlet channel. The blocking plate is slidably connected to the lower water outlet channel through the cooperation of a slider at its upper end and a transverse groove on the top surface of the lower water outlet channel. A transverse toothed plate is fixedly arranged on one side of the blocking plate. The transverse toothed plate meshes with a driving gear. One end of the central axis of the driving gear is fixedly connected to one end of a third rotating shaft. The other end of the third rotating shaft is fixedly connected to the central axis of a rotating gear. The rotating gear meshes with a vertical toothed plate. The vertical toothed plate is fixedly installed at the bottom of the vertical rod of the L-shaped connecting rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this sponge city green space water storage collector, the original vertical filter screen is optimized into a spherical filter screen. By using the second rotating shaft, the spherical filter screen can rotate, so that the impurities originally located at the lower position of the filter barrel are turned to the upper part as the spherical filter screen rotates, which is convenient for people to clean the impurities from the opening of the filter barrel. At the same time, the spherical filter screen can still maintain the filtering ability when rotating. Compared with directly disassembling and cleaning in the prior art, it can not only conveniently clean the impurities below the filter screen, but also ensure the continuity and efficiency of the filtering work of the filter screen. In this sponge city green space water storage collector, through the setting of the impeller, the rotation of the spherical filter screen can be realized by driving the impeller through the impact force of water flow. This not only simplifies the rotation mechanism, makes the operation more convenient, but also reduces the demand for additional power equipment, thereby reducing the cost investment.

Specific implementation manner

[0014] The present invention will be further described below in conjunction with embodiments, and the purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0015] Please refer to Figure 1 - Figure 7 , a sponge city green space water storage collector, including a rainwater diversion well. The water inlet pipe of the rainwater diversion well enters the interior through the ground water inlet. The water outlet pipe of the rainwater diversion well is communicated with the sewage interception hanging basket device. The water outlet pipe of the sewage interception hanging basket device is communicated with the rainwater runoff device. The water outlet pipe of the rainwater runoff device is communicated with the PP module reservoir. The water outlet pipe of the PP module reservoir is communicated with the underground integrated machine. The water outlet pipe of the underground integrated machine is communicated with the PP module clean water tank. The sewage interception hanging basket device includes a filter barrel 1, a water inlet pipe communicated with the left side of the filter barrel 1, a water outlet pipe 2 communicated with the right side of the filter barrel 1, and a thickened plate 3 fixedly connected to the inner wall of the right side of the filter barrel 1. A through hole is provided in the middle of the thickened plate 3, and the through hole is communicated with the water inlet pipe and the water outlet pipe 2. A spherical filter screen 4 for blocking impurities in the water is arranged in the through hole. The middle of the spherical filter screen 4 is rotatably connected to the thickened plate 3 through a second rotating shaft 17.

[0016] In the sponge city green space water storage collector of the present invention, as Figure 1 shown, when rainwater converges into the water collection port from areas such as roofs, roads, squares, and green belts through the ground slope, permeable pavement, or drainage pipe network, it flows into the rainwater diversion well, enters the PP module reservoir through the sewage interception hanging basket device and the rainwater runoff device, and enters the PP module clean water tank after being processed by the underground integrated machine; When the filter barrel 1 in the sewage interception hanging basket device is performing the filtering operation, the spherical filter screen 4 performs the filtering work. When impurities are washed to the lower position and are difficult to clean and get stuck, the spherical filter screen 4 can be rotated to make the second rotating shaft 17 rotate in the thickened plate 3, realizing the rotation of the spherical filter screen 4, rotating the lower position to the upper position, so that the impurities originally located at the lower position of the filter barrel 1 are rotated to the upper position along with the rotation of the spherical filter screen 4, thus facilitating people to clean the impurities from the opening of the filter barrel 1; By optimizing the original vertical filter screen into a spherical filter screen 4 and using the second rotating shaft 17, the spherical filter screen 4 can rotate, enabling the impurities originally located at the lower position of the filter barrel 1 to be rotated to the upper part as the spherical filter screen 4 rotates. This facilitates people to clean the impurities from the opening of the filter barrel 1. At the same time, the spherical filter screen 4 can still maintain its filtering ability during rotation. Compared with the prior art of directly disassembling and cleaning, it can not only ensure the convenient cleaning of impurities in the lower position, but also ensure the continuity and efficiency of the filtering work of the filter screen; As a preferred technical solution of the present invention, a cavity is provided inside the thickening plate 3, and one end of the second rotating shaft 17 extends into the cavity and is fixedly connected to the central axis of the rotating wheel 29 inside the cavity.

[0017] As a preferred technical solution of the present invention, an impeller 7 is arranged inside the water outlet pipe 2. The impeller 7 is rotatably connected to the inner wall of the water outlet pipe 2 through a first rotating shaft 15. One end of the first rotating shaft 15 penetrates through the water outlet pipe 2 and is fixedly connected to the central axis of the pulley 18 inside the installation box 5. A transmission belt 19 is sleeved on the pulley 18, and the end of the transmission belt 19 away from the pulley 18 is sleeved on the rotating wheel 29.

[0018] Specifically, through the arrangement of the impeller 7, under the impact of the rainwater flow, the impeller 7 is driven to rotate. The impeller 7 drives the first rotating shaft 15 to rotate, and the first rotating shaft 15 drives the pulley 18 located inside the installation box 5 to rotate. The pulley 18 rotates, driving the transmission belt 19 to rotate, and driving the rotating wheel 29 and the second rotating shaft 17 to rotate. At this time, the second rotating shaft 17 smoothly drives the spherical filter screen 4 to rotate; Through the impeller 7, the rotation of the spherical filter screen 4 can be realized by driving the impeller 7 through the impact force of the water flow. This not only simplifies the rotation mechanism, makes the operation more convenient, but also reduces the demand for additional power equipment, thereby reducing the cost investment.

[0019] It should be noted that in order to ensure that the rotation direction of the impeller 7 corresponds to the clockwise rotation of the spherical filter screen 4, the blades of the impeller 7 are designed to be helically inclined in the clockwise direction and are distributed in an involute shape from the leading edge to the trailing edge to adapt to the water flow impact direction.

[0020] As a preferred technical solution of the present invention, an arc-shaped extrusion plate 20 is arranged above the spherical filter screen 4. The top surface of the arc-shaped extrusion plate 20 is fixedly connected to the bottom end of the lifting plate 6. The lifting plate 6 is slidably connected to the thickening plate 3. The top end of the lifting plate 6 is fixedly connected to one end of a support rod, and the other end of the support rod is fixedly connected to an L-shaped connecting rod 12. The horizontal bar of the L-shaped connecting rod 12 passes through the strip-shaped through hole opened on the filter barrel 1, and the vertical bar of the L-shaped connecting rod 12 is slidably connected to the installation box 5. A plurality of positioning holes 26 are opened on the vertical bar, and an installation plate 14 is fixedly connected to the top of the installation box 5. A tightening bolt 25 that can be inserted into the positioning hole 26 is installed on the outer wall of the installation plate 14.

[0021] Specifically, to prevent the spherical filter screen 4 from rotating under the impact of water flow during the filtering operation, the L-shaped connecting rod 12 can be pressed down to drive it to slide within the strip-shaped through-hole and also slide within the installation box 5. When the L-shaped connecting rod 12 moves downward, it can drive the lifting plate 6 and the arc-shaped pressing plate 20 to move downward, causing the arc-shaped pressing plate 20 to press the spherical filter screen 4. Through friction, the spherical filter screen 4 is limited. On the premise that the spherical filter screen 4 is limited, the impeller 7 is also limited. Meanwhile, to ensure that the arc-shaped pressing plate 20 will not loosen after pressing the spherical filter screen 4, the tightening bolt 25 can be rotated, and the tightening bolt 25 is inserted into the positioning hole 26 through the mounting plate 14 to complete the limit of the L-shaped connecting rod 12 and ensure the stability of the arc-shaped pressing plate 20.

[0022] As a preferred technical solution of the present invention, the water outlet pipe 2 includes an upper water outlet channel 8 and a lower water outlet channel 9. The upper water outlet channel 8 is communicated with the through-hole of the thickening plate 3, and the lower water outlet channel 9 is not communicated with the through-hole of the thickening plate 3. An inlet 11 for communicating with the lower water outlet channel 9 is provided at one end of the upper water outlet channel 8 close to the spherical filter screen 4.

[0023] As a preferred technical solution of the present invention, a blocking plate 10 for blocking the inlet 11 is provided at the top of the lower water outlet channel 9. The blocking plate 10 is slidably connected to the lower water outlet channel 9 through the cooperation of the slider 16 at its upper end and the transverse groove 24 on the top surface of the lower water outlet channel 9. A transverse toothed plate 28 is fixedly provided on one side of the blocking plate 10. The transverse toothed plate 28 meshes with the driving gear 27. One end of the central axis of the driving gear 27 is fixedly connected to one end of the third rotating shaft 23, and the other end of the third rotating shaft 23 is fixedly connected to the central axis of the rotating gear 22. The rotating gear 22 meshes with the vertical toothed plate 13, and the vertical toothed plate 13 is fixedly installed at the bottom of the vertical rod of the L-shaped connecting rod 12.

[0024] Specifically, when the spherical filter screen 4 needs to rotate, the L-shaped connecting rod 12 is operated to open the arc-shaped pressing plate 20, so that the spherical filter screen 4 loses its restraint. When the L-shaped connecting rod 12 moves upward, it drives the vertical toothed plate 13 to move upward within the installation box 5. The vertical toothed plate 13 meshes with the rotating gear 22 and rotates, driving the third rotating shaft 23 to rotate, driving the driving gear 27 to rotate. The driving gear 27 meshes with the transverse toothed plate 28, causing the transverse toothed plate 28 to drive the blocking plate 10 to move. When the blocking plate 10 moves, it drives the slider 16 on its top surface to move within the transverse groove 24. During the movement of the blocking plate 10, the inlet 11 is closed. At this time, the lower water outlet channel 9 is closed, and after the rainwater is filtered by the spherical filter screen 4, it can only pass through the upper water outlet channel 8. At this time, the diameter through which the rainwater can flow is reduced, the flow rate of the rainwater increases, and the impact force generated by the water flow on the impeller 7 is enhanced. According to the principle of fluid mechanics, this enhances the impact force generated by the water flow on the impeller 7, thereby providing a greater driving force for the impeller 7 to rotate.

[0025] After the cleaning is completed, lower the L-shaped connecting rod 12, driving the vertical toothed plate 13 to move downward in the installation box 5, so that the vertical toothed plate 13 meshes with and rotates the gear 22, driving the third rotating shaft 23, the driving gear 27 to mesh with the horizontal toothed plate 28, and then driving the plugging plate 10 to move, opening the water inlet 11, and the water automatically flows downward, enters from the water inlet 11. On the premise that the rainfall is not large, the impeller 7 is not impacted by the rainwater, reducing the probability of the impeller 7 being soaked in the rainwater for a long time to a certain extent.

[0026] It should be noted that the connections between the first rotating shaft 15 and the upper water outlet channel 8, between the second rotating shaft 17 and the thickening plate 33, and between the third rotating shaft 23 and the lower water outlet channel 9 are all treated with oil seals, which can prevent the water in the filter barrel 1, the upper water outlet channel 8 and the lower water outlet channel 9 from leaking out.

[0027] For this sponge city green space water storage collector, by optimizing the original vertical filter screen into a spherical filter screen and using the second rotating shaft, the spherical filter screen can rotate, so that the impurities originally located at the lower position of the filter barrel are rotated to the upper part as the spherical filter screen rotates, facilitating people to clean the impurities from the opening of the filter barrel. At the same time, the spherical filter screen can still maintain the filtering ability when rotating. Compared with the prior art of directly disassembling and cleaning, it can not only conveniently clean the impurities below the filter screen, but also ensure the continuity and efficiency of the filter screen filtering work; through the setting of the impeller, the rotation of the spherical filter screen can be realized by driving the impeller by the impact force of the water flow, which not only simplifies the rotation mechanism, makes the operation more convenient, but also reduces the demand for additional power equipment, thus reducing the cost investment.

[0028] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of rights of the present invention accordingly. Any equivalent changes made by using the content of the specification and drawings of the present invention are included in the scope of rights of the present invention.
