Description

Technical Field

[0001] The invention relates to the technical field of rainwater purification, in particular to rainwater garden recycling equipment with a purification function. Background Art

[0002] Rainwater is one of the important water resources in nature, especially in arid and semi-arid areas. The effective use of rainwater resources is of great significance to alleviate water shortage. However, in cities, due to the increase of impervious areas, a large amount of rainwater runoff is directly discharged into water bodies without treatment, which not only wastes water resources, but also may pollute the water environment. Through the multi-layer filtration of rain gardens, the natural water cycle is simulated to complete the filtration of rainwater.

[0003] However, most of the current rain gardens fall into the water through channels or directly along the edges. In the long run, this may lead to the accumulation of impurities at the edges, affecting the subsequent rainwater filtration, and less rainwater is filtered in other parts, making it impossible to fully utilize the rain garden. Furthermore, if too much rainwater flows directly into the rain garden for filtration, it may cause too much rain on the surface of the rain garden, affecting its use. Summary of the invention

[0004] The purpose of the present invention is to provide a rainwater garden recycling device with purification function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: The reuse equipment includes a natural filtration tank, a collecting mechanism, an anti-accumulation mechanism, an angle adjustment mechanism and a water treatment mechanism. The natural filtration tank is provided with an anti-accumulation mechanism, and the natural filtration tank is provided with an angle adjustment mechanism. The collecting mechanism is connected to the anti-accumulation mechanism, and the angle adjustment mechanism is connected to the water treatment mechanism. The water treatment mechanism re-processes the filtered rainwater, and the anti-accumulation mechanism is used to prevent rainwater impurities from accumulating in one place.

[0006] In the reuse equipment, the equipment is used to collect and filter rainwater. The natural filter tank can filter most of the impurities in the rainwater. The collection mechanism is used to collect rainwater and flow the rainwater to the natural filter tank through the anti-accumulation mechanism. During the filtration process of rainwater in the natural filter tank, the angle adjustment mechanism assists the flow of the initially filtered rainwater by adjusting the pipe lifting in the natural filter tank, and the water treatment mechanism performs secondary filtration on the initially filtered rainwater.

[0007] Furthermore, the natural filter trough is a trough-shaped structure placed on the ground. From top to bottom, the natural filter trough comprises an aquifer, a covering layer, a planting soil layer, a sand layer, and a gravel layer. The surface of the natural filter trough is covered with vegetation. The natural filter trough is circular when viewed from above. An anti-accumulation mechanism is provided on the top of the natural filter trough, a collection mechanism is provided on the edge of the natural filter trough, and an angle adjustment mechanism is provided on the gravel layer of the natural filter trough.

[0008] In the natural filter tank, the natural filter tank is used to filter the rainwater for the first time in a relatively comprehensive manner, filtering out some visible larger impurities. From top to bottom, the natural filter tank is composed of aquifer, covering layer, planting soil layer, sand layer, and gravel layer. Through multi-layer filtration, it simulates the natural water cycle and filters the rainwater through structural layers such as the soil layer. It can initially filter out impurities in the rainwater more completely. The density of the gravel layer is relatively small, which can make the rainwater gather into a larger water flow and flow out to other institutions, thereby completing the primary filtration of the rainwater.

[0009] Furthermore, the collecting mechanism includes a drainage water collecting channel, a driving motor, a driving baffle, and a rubber pad. The drainage water collecting channel is placed on the ground, the drainage water collecting channel is open, the end of the drainage water collecting channel away from the natural filtration tank is closed, and the end of the drainage water collecting channel close to the natural filtration tank is open. The drainage water collecting channel is provided with a plurality of arc grooves, and a plurality of driving baffles are provided. The number of driving baffles is the same as the number of arc grooves. A moving chain is fastened to the bottom of the driving baffle. The fixed end of the driving motor is fastened to the outer wall of the drainage water collecting channel. A circular driving hole is provided at the connection between the drainage water collecting channel and the driving motor. The output end of the driving motor passes through the circular driving hole and engages with the moving chain. The rubber pad covers the surface of the drainage water collecting channel, the driving baffle is placed between the rubber pad and the drainage water collecting channel, and the drainage water collecting channel is connected to the anti-accumulation mechanism.

[0010] In the collection mechanism, the mechanism is used to collect rainwater and send it to the anti-accumulation mechanism after preliminary filtration, and then the anti-accumulation mechanism sends it to the natural filter tank for filtration. The drainage water collection channel is used to collect rainwater. The driving motor drives the moving chain to move, so that the angle between the driving baffle and the bottom wall of the drainage water collection channel changes, so as to adapt to different water flows. The rubber pad covers the wall surface of the drainage water collection channel and the driving baffle, which can prevent the water flow from causing the moving chain to rust or affect the normal use of the driving motor, and can extend the service life of the collection mechanism. When rainwater falls into the drainage water collection channel, it flows along the drainage water collection channel to the unclosed end. Since the rainwater contains more impurities when it just falls, the angle between the driving baffle and the drainage water collection channel is the largest in the initial state. In this way, when rainwater flows through, some impurities can be retained at the angle between the driving baffle and the drainage water collection channel. At the same time, this can also control the flow rate of rainwater. At a slower flow rate, impurities in rainwater can be more easily precipitated, and thus can be better retained at the angle between the driving baffle and the drainage water collection channel. Thereafter, there are relatively few impurities in rainwater because the amount flowing through is consistent. If the amount of rainwater is small, the driving motor drives the moving chain to move, so that the angle between the driving baffles becomes smaller, and rainwater can pass through the driving baffle faster. However, due to the small amount, some impurities can still be retained at the angle between the driving baffle and the drainage water collection channel. If the amount of rainwater is large, the angle remains unchanged, which can not only filter out some impurities, but also control the flow rate of rainwater to avoid excessive flow rate affecting subsequent filtration.

[0011] Furthermore, the anti-accumulation mechanism includes a spiral pipe, one end of the spiral pipe is fastened to one end of the drainage and water collection channel close to the natural filter tank, the spiral pipe spirals from the edge of the natural filter tank to the center, and a plurality of flow holes are provided on a surface of the spiral pipe close to the natural filter tank. The anti-accumulation mechanism also includes a reset spring, a through-hole baffle and a driving vertical plate. There are a plurality of reset springs, and there are a plurality of through-hole baffles. The number of reset springs and through-hole baffles is the same, and the number of reset springs is less than the number of flow holes in the spiral pipe. One end of the reset spring is fastened to the outer surface of the spiral pipe through a fixed plate, and the reset spring is placed on a side of the spiral pipe close to the natural filter tank. The end of the reset spring away from the fixed plate is fastened to the driving vertical plate, the curvature of the through-hole baffle is consistent with the curvature of the spiral pipe, the through-hole baffle is slidably connected to the inner wall of the spiral pipe, and the through-hole baffle is fastened to the driving vertical plate.

[0012] In the anti-accumulation mechanism, the mechanism disperses rainwater to the position of the natural filter tank by setting up a spiral pipe. Normal rainwater seeps in from the edge of the natural filter tank, which easily leads to the accumulation of impurities at the edge of the natural filter tank where rainwater flows, while the other edge parts and middle parts of the natural filter tank filter less rainwater, and the natural filter tank cannot be fully utilized. At the same time, the setting of the spiral pipe can also extend the flow distance of rainwater. In this process, impurities in the rainwater will also settle. As the spiral pipe flows out to the natural filter tank, it can be filtered faster. A number of flow holes are set at the bottom of the spiral pipe. Under normal conditions, the flow holes in the outer circle are blocked by the through-hole baffle, and only the internal flow holes are in a state of being always open. The through-hole baffle is driven by a reset spring and a vertical plate. Control opening and closing. When the amount of rainwater is small, when the water flows through the outer spiral pipe, it will not cause too much impact force on the through-hole baffle and the driving vertical plate on the flow hole. Therefore, when the rainwater passes, the outer flow hole is in a closed state; when the amount of rainwater is large, the rainwater flows through the outer flow hole, which will cause a certain impact on the through-hole baffle on the surface of the flow hole, causing the through-hole baffle to slide inside the spiral pipe, and the driving vertical plate fastened to the through-hole baffle will move together with the through-hole baffle, and the driving vertical plate is fastened to the return spring. Therefore, the return spring will be compressed at this time. After the amount of rainwater becomes smaller, the impact force of rainwater on the through-hole baffle is less than the elastic force of the return spring. Therefore, the return spring is reset, so that the through-hole baffle covers the flow hole again, which can prevent the accumulation of impurities at the edge.

[0013] Furthermore, the angle adjustment mechanism includes a perforated tube and an operating chamber, the perforated tube is connected to the natural filter tank, the perforated tube is placed in the gravel layer of the natural filter tank, the upper surface of the perforated tube is provided with holes, an operating chamber is provided at the bottom of the perforated tube, the curvature of the top of the operating chamber is consistent with the curvature of the lower half of the perforated tube, one end of the perforated tube is sealed, and the other end of the perforated tube is connected to the water treatment mechanism, the angle adjustment mechanism also includes a fixing buckle, a rotating shaft and a lifting hydraulic cylinder, the fixing buckle is fastened to one end of the perforated tube close to the water treatment mechanism, two rotating shafts are provided, the side of the fixing buckle is rotatably connected to the two rotating shafts, the rotating shaft passes through the operating chamber, the rotating shaft is placed in the operating chamber, the end of the rotating shaft away from the fixing buckle is fastened to the side wall of the operating chamber, the fixed end of the lifting hydraulic cylinder is fastened to the bottom wall of the operating chamber, a through hole is provided at the operating chamber directly above the lifting hydraulic cylinder, the diameter of the output end of the lifting hydraulic cylinder is consistent with the diameter of the through hole, and the output end of the lifting hydraulic cylinder fits the side of the perforated tube close to the seal.

[0014] In the angle adjustment mechanism, the flow rate of rainwater is adjusted by adjusting the inclination angle of the perforated pipe and the ground. The perforated pipe is placed in the gravel layer of the natural filtration tank to collect rainwater that has completed preliminary filtration. A number of holes are provided on the upper part of the perforated pipe, and the preliminarily filtered rainwater enters the perforated pipe through the holes. When the amount of rainwater is large, the rainwater can flow along the water flow to a suitable position and then be pumped out to the water treatment mechanism by a pump. When the amount of rainwater is small, the lifting hydraulic cylinder is started to lift the closed end of the perforated pipe. At this time, the fixed buckle and the rotating shaft rod rotate relative to each other, so that the rainwater can flow to a suitable position. The operating room is beveled from the fixed buckle to the side close to the water treatment mechanism, so that the perforated pipe will not be disturbed when it is rotated and raised.

[0015] Furthermore, the water treatment mechanism includes a shell, a servo motor, a main shaft, an inner filter and an outer filter. The shell is placed on the ground and is connected to the shell through a hose and a perforated pipe. The fixed end of the servo motor is tightly connected to the shell, and the output end of the servo motor is tightly connected to the main shaft. The main shaft is placed in the shell, and the end of the main shaft away from the servo motor is rotatably connected to the bottom wall of the shell. An impeller is provided on the main shaft, and an inner filter and an outer filter are provided in the shell. The inner filter, the outer filter and the shell have the same axis. The top view diameter of the inner filter is smaller than the top view diameter of the outer filter. A dividing filter is provided in the middle of the inner filter. The water treatment mechanism also includes a first conducting pipe and a second conducting pipe. The bottom and side wall of the shell are respectively provided with a first opening and a second opening. One end of the first conducting pipe is connected to the first opening of the shell, and one end of the second conducting pipe is connected to the second opening of the shell. The first conducting pipe and the second conducting pipe are respectively installed with a first flow regulating valve and a second flow regulating valve.

[0016] In the water treatment mechanism, the mechanism performs secondary filtration on the rainwater after the primary filtration, the filtration aperture of the inner filter is larger than the filtration aperture of the outer filter, and one end of the first conducting pipe is connected to the first opening of the shell, and one end of the second conducting pipe is connected to the second opening of the shell, the first conducting pipe can flow the rainwater passing through the inner filter, and the second conducting pipe can flow the rainwater passing through the outer filter, so as to determine which degree of filtration of rainwater is needed according to different needs, the rainwater is discharged after being filtered by the inner filter, and the rainwater after the primary filtration is transported to the water treatment mechanism through a pump and a hose, and then the servo is used to filter the rainwater. The servo motor starts to drive the main shaft to rotate, and the impeller is rotated together with it, so that the rainwater is rotated together, and the impurities will be thrown to the periphery due to the rotation, so that the impurities and rainwater can be roughly distinguished for easy filtering. If relatively pure rainwater is needed, the first flow regulating valve will close the first conduction pipe, and the second conduction pipe will be turned on, and the rainwater will be discharged after double filtration by the inner filter and the outer filter; if the required purity of the rainwater is not very high, the second flow regulating valve will close the second conduction pipe, and the first conduction pipe will be turned on, and the rainwater will flow out through the split filter to the first conduction pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: after being started, the present invention drives the moving chain to move by a driving motor, so that the angles of the driving baffle and the bottom wall of the drainage and water collection channel change, so as to adapt to different water flows, and can preliminarily filter out impurities. It can also control the flow rate of rainwater to avoid excessive flow rate affecting subsequent filtration, and then disperse the rainwater through the spiral pipe to the position of the natural filter tank to avoid the accumulation of rainwater impurities at the edge of the natural filter tank. When the amount of rainwater is small, the water flow will not cause too much impact force on the through-hole baffle on the flow hole. Therefore, when rainwater passes through, the outer flow holes are in a closed state; when the amount of rainwater is large, the rainwater causes a certain impact on the through-hole baffle on the surface of the flow hole, causing the through-hole baffle to slide inside the spiral pipe, and the flow hole covered by the through-hole baffle opens. The positioning spring will be compressed. After the amount of rainwater becomes smaller, the impact force of rainwater on the through-hole baffle is less than the elastic force of the reset spring. Therefore, the reset spring is reset, so that the through-hole baffle covers the flow hole again. Then the rainwater completes the initial filtration through the natural filter trough and reaches the perforated pipe. When the amount of rainwater is large, the rainwater can flow to the appropriate position along the water flow and then be pumped out to the water treatment mechanism through the pump. When the amount of rainwater is small, the lifting hydraulic cylinder is started to lift the closed end of the perforated pipe. At this time, the fixed buckle and the rotating shaft rotate relative to each other, and the rainwater can flow to the appropriate position. Then the rainwater is filtered for the second time. The degree of filtration of rainwater is determined according to different needs. If purer rainwater is needed, the rainwater is discharged after being double filtered by the inner filter and the outer filter. If the required purity of rainwater is not very high, the rainwater flows out through the split filter to the first conduction pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the reuse equipment, the equipment is used to collect and filter rainwater. The natural filter tank 1 can filter most of the impurities in the rainwater. The collection mechanism 2 is used to collect rainwater and let the rainwater flow to the natural filter tank 1 through the anti-accumulation mechanism 3. During the filtering process of rainwater in the natural filter tank 1, the angle adjustment mechanism 4 assists the flow of the initially filtered rainwater by adjusting the pipe lifting in the natural filter tank 1. The water treatment mechanism 5 performs secondary filtration on the initially filtered rainwater.

[0023] The natural filter tank 1 is a trough-shaped structure placed on the ground. The natural filter tank 1 comprises a water storage layer, a covering layer, a planting soil layer, a sand layer and a gravel layer from top to bottom. The surface of the natural filter tank 1 is covered with vegetation. The natural filter tank 1 is circular when viewed from above. An anti-accumulation mechanism 3 is provided on the top of the natural filter tank 1. A collecting mechanism 2 is provided on the edge of the natural filter tank 1. The gravel layer of the natural filter tank 1 is provided with an angle adjustment mechanism 4.

[0024] In the natural filter tank 1, the natural filter tank 1 is used to perform a relatively comprehensive initial filtration of rainwater to filter out some visible larger impurities. The natural filter tank 1 is composed of an aquifer, a covering layer, a planting soil layer, a sand layer, and a gravel layer from top to bottom. Through multi-layer filtration, the natural water cycle is simulated, and rainwater is filtered through structural layers such as the soil layer. Impurities in the rainwater can be initially filtered out relatively completely. The density of the gravel layer is relatively small, which can allow the rainwater to gather into a larger water flow and flow out to other organizations, thereby completing a single filtration of the rainwater.

[0025] The collecting mechanism 2 includes a drainage and water collecting channel 21, a driving motor 22, a driving baffle 23, and a rubber pad 24. The drainage and water collecting channel 21 is placed on the ground and is open. The end of the drainage and water collecting channel 21 away from the natural filtration tank 1 is closed, and the end of the drainage and water collecting channel 21 close to the natural filtration tank 1 is open. The drainage and water collecting channel 21 is provided with a plurality of arc grooves, and the driving baffle 23 is provided with a plurality of driving baffles. The number of the driving baffles 23 is the same as the number of the arc grooves. A moving chain is fastened to the bottom of the driving baffle 23. The fixed end of the driving motor 22 is fastened to the outer wall of the drainage and water collecting channel 21. A circular driving hole is provided at the connection between the drainage and water collecting channel 21 and the driving motor 22. The output end of the driving motor 22 passes through the circular driving hole and engages with the moving chain. The rubber pad 24 covers the surface of the drainage and water collecting channel 21. The driving baffle 23 is placed between the rubber pad 24 and the drainage and water collecting channel 21. The drainage and water collecting channel 21 is connected to the anti-accumulation mechanism 3.

[0026] In the collecting mechanism 2, the mechanism is used to collect rainwater and send it to the anti-accumulation mechanism 3 after preliminary filtration, and then the anti-accumulation mechanism 3 sends it to the natural filtration tank 1 for filtration. The drainage water collection channel 21 is used to collect rainwater. The driving motor 22 drives the moving chain to move, so that the angle of the driving baffle 23 and the bottom wall of the drainage water collection channel 21 changes, so as to adapt to different water flows. The rubber cushion 24 covers the wall surface of the drainage water collection channel 21 and the driving baffle 23, which can prevent the water flow from causing the moving chain to rust or affect the normal use of the driving motor 22, and can extend the service life of the collecting mechanism 2. When rainwater falls into the drainage water collection channel 21, it flows along the drainage water collection channel 21 toward the unclosed end. Since the rainwater contains more impurities when it just falls, the driving baffle 23 and the drainage water collection channel 21 are clamped in the initial state. The angle is the largest, so that when rainwater flows through, some impurities can be retained at the angle between the driving baffle 23 and the drainage water collection channel 21. At the same time, this can also control the flow rate of rainwater. At a slower flow rate, impurities in rainwater can be more easily precipitated, so they can be better retained at the angle between the driving baffle 23 and the drainage water collection channel 21. Thereafter, there are relatively few impurities in rainwater, because the amount flowing through is consistent. If the amount of rainwater is small, the driving motor 22 drives the moving chain to move, so that the angle between the driving baffles 23 becomes smaller, and the rainwater can pass through the driving baffle 23 faster. However, due to the small amount, some impurities can still be retained at the angle between the driving baffle 23 and the drainage water collection channel 21; if the amount of rainwater is large, the angle remains unchanged, which can not only filter out some impurities, but also control the flow rate of rainwater to avoid excessive flow rate affecting subsequent filtration.

[0027] The anti-accumulation mechanism 3 includes a spiral pipe 31, one end of the spiral pipe 31 is fastened to one end of the drainage and water collecting channel 21 close to the natural filter tank 1, the spiral pipe 31 spirals from the edge of the natural filter tank 1 to the center, and a plurality of flow holes are provided on one surface of the spiral pipe 31 close to the natural filter tank 1, the anti-accumulation mechanism 3 also includes a reset spring 32, a through-hole baffle 33 and a driving vertical plate 34, a plurality of reset springs 32 are provided, a plurality of through-hole baffles 33 are provided, the number of reset springs 32 and through-hole baffles 33 are the same, the number of reset springs 32 is less than the number of flow holes in the spiral pipe 31, one end of the reset spring 32 is fastened to the outer surface of the spiral pipe 31 through a fixed plate, the reset spring 32 is placed on one side of the spiral pipe 31 close to the natural filter tank 1, the end of the reset spring 32 away from the fixed plate is fastened to the driving vertical plate 34, the curvature of the through-hole baffle 33 is consistent with that of the spiral pipe 31, the through-hole baffle 33 is slidably connected to the inner wall of the spiral pipe 31, and the through-hole baffle 33 is fastened to the driving vertical plate 34.

[0028] In the anti-accumulation mechanism 3, the mechanism disperses rainwater to the position of the natural filter tank 1 by setting a spiral pipe 31. Normal rainwater infiltrates from the edge of the natural filter tank 1, which easily leads to the accumulation of impurities at the edge of the natural filter tank 1 where rainwater flows, while the other edge parts and middle parts of the natural filter tank 1 filter less rainwater, and the natural filter tank 1 cannot be fully utilized. At the same time, the setting of the spiral pipe 31 can also extend the flow range of rainwater. In this process, impurities in the rainwater will also settle. As the spiral pipe 31 flows out into the natural filter tank 1, it can be filtered faster. A number of flow holes are set at the bottom of the spiral pipe 31. Under normal conditions, the flow holes of the outer circle are blocked by the through-hole baffle 33, and only the internal flow holes are in a state of being always open. The through-hole baffle 33 controls the opening and closing through the reset spring 32 and the driving vertical plate 34. When the amount of rainwater is small, when the water flows through the outer spiral pipe 31, it will not cause too much impact force on the through-hole baffle 33 and the driving vertical plate 34 on the flow hole. Therefore, when the rainwater passes, the outer flow hole is in a closed state; when the amount of rainwater is large, the rainwater flows through the outer flow hole, which will cause a certain impact on the through-hole baffle 33 on the surface of the flow hole, causing the through-hole baffle 33 to slide inside the spiral pipe 31, and the driving vertical plate 34 fastened to the through-hole baffle 33 will move together with the through-hole baffle 33, and the driving vertical plate 34 is fastened to the return spring 32. Therefore, the return spring 32 will be compressed at this time. After the amount of rainwater becomes smaller, the impact force of rainwater on the through-hole baffle 33 is less than the elastic force of the return spring 32, so the return spring 32 is reset, so that the through-hole baffle 33 covers the flow hole again, which can prevent the accumulation of impurities at the edge.

[0029] The angle adjustment mechanism 4 includes a perforated pipe 41 and an operating chamber 42. The perforated pipe 41 is connected to the natural filtration tank 1. The perforated pipe 41 is placed in the gravel layer of the natural filtration tank 1. The upper surface of the perforated pipe 41 is provided with holes. The bottom of the perforated pipe 41 is provided with an operating chamber 42. The curvature of the top of the operating chamber 42 is consistent with the curvature of the lower half of the perforated pipe 41. One end of the perforated pipe 41 is sealed, and the other end of the perforated pipe 41 is connected to the water treatment mechanism 5. The angle adjustment mechanism 4 also includes a fixing buckle 43, a rotating shaft 44 and a lifting hydraulic cylinder 45. The fixing buckle 43 and the perforated pipe 41 are close to the water treatment mechanism 5. The ends are tightly connected, two rotating shafts 44 are provided, the side of the fixed buckle 43 is rotatably connected to the two rotating shafts 44, the rotating shaft 44 passes through the operating room 42, the rotating shaft 44 is placed in the operating room 42, the end of the rotating shaft 44 away from the fixed buckle 43 is tightly connected to the side wall of the operating room 42, the fixed end of the lifting hydraulic cylinder 45 is tightly connected to the bottom wall of the operating room 42, and the operating room 42 is provided with a through hole directly above the lifting hydraulic cylinder 45, the output end diameter of the lifting hydraulic cylinder 45 is consistent with the diameter of the through hole, and the output end of the lifting hydraulic cylinder 45 is in contact with the side of the perforated tube 41 close to the seal.

[0030] In the angle adjustment mechanism 4, the flow rate of rainwater is adjusted by adjusting the inclination angle of the perforated pipe 41 and the ground. The perforated pipe 41 is placed in the gravel layer of the natural filtration tank 1 to collect rainwater that has completed preliminary filtration. The upper part of the perforated pipe 41 is provided with a plurality of holes, and the preliminarily filtered rainwater enters the perforated pipe 41 through the holes. When the amount of rainwater is large, the rainwater can flow along the water flow to a suitable position and then be pumped out to the water treatment mechanism 5 by a pump. When the amount of rainwater is small, the lifting hydraulic cylinder 45 is started to lift the closed end of the perforated pipe 41. At this time, the fixed buckle 43 and the rotating shaft 44 rotate relative to each other, so that the rainwater can flow to a suitable position. The operating room 42 is beveled from the fixed buckle 43 to the side close to the water treatment mechanism 5, so that the perforated pipe 41 will not be disturbed when it is rotated and lifted.

[0031] The water treatment mechanism 5 includes a housing 51, a servo motor 52, a main shaft 53, an inner filter 54 and an outer filter 55. The housing 51 is placed on the ground and is connected to the perforated pipe 41 through a hose. The fixed end of the servo motor 52 is tightly connected to the housing 51, and the output end of the servo motor 52 is tightly connected to the main shaft 53. The main shaft 53 is placed in the housing 51, and one end of the main shaft 53 away from the servo motor 52 is rotatably connected to the bottom wall of the housing 51. An impeller is arranged on the main shaft 53, and an inner filter 54 and an outer filter 55 are arranged in the housing 51. The inner filter 54 and the outer filter 55 are connected to the housing 51. The axes of the net 55 and the shell 51 are consistent, the top view diameter of the inner filter 54 is smaller than the top view diameter of the outer filter 55, and a partition filter is arranged in the middle of the inner filter 54. The water treatment mechanism 5 also includes a first conducting pipe 56 and a second conducting pipe 57. The bottom and the side wall of the shell 51 are respectively provided with a first opening and a second opening. One end of the first conducting pipe 56 is connected to the first opening of the shell 51, and one end of the second conducting pipe 57 is connected to the second opening of the shell 51. The first conducting pipe 56 and the second conducting pipe 57 are respectively installed with a first flow regulating valve and a second flow regulating valve.

[0032] In the water treatment mechanism 5, the mechanism performs secondary filtration on the rainwater after the primary filtration. The filtration aperture of the inner filter 54 is larger than the filtration aperture of the outer filter 55, and one end of the first conducting pipe 56 is connected to the first opening of the shell 51, and one end of the second conducting pipe 57 is connected to the second opening of the shell 51. The first conducting pipe 56 can flow the rainwater passing through the inner filter 54, and the second conducting pipe 57 can flow the rainwater passing through the outer filter 55. In this way, the required filtering degree of rainwater is determined according to different needs. The rainwater is discharged after being filtered by the inner filter 54, and the rainwater that has been filtered for the primary time is transported to the water treatment mechanism 5 through a pump and a hose. Afterwards, the servo motor 52 starts to drive the main shaft 53 to rotate, and the impeller is rotated together, so that the rainwater is rotated together, and the impurities will be thrown to the periphery due to the rotation, so that the impurities and rainwater can be roughly distinguished, which is convenient for filtering. If purer rainwater is needed, the first flow regulating valve closes the first conducting pipe 56, and the second conducting pipe 57 is turned on, and the rainwater is discharged after being double filtered by the inner filter 54 and the outer filter 55; if the required purity of the rainwater is not very high, the second flow regulating valve closes the second conducting pipe 57, and the first conducting pipe 56 is turned on, and the rainwater flows out through the split filter to the first conducting pipe 56.

[0033] Working principle of the present invention: After starting, the present invention drives the moving chain to move through the driving motor 22, so that the angle of the driving baffle 23 and the bottom wall of the drainage and water collection channel 21 changes, so as to adapt to different water flows, and can preliminarily filter out impurities. It can also control the flow rate of rainwater to avoid excessive flow rate affecting subsequent filtration, and then disperse the rainwater to the position of the natural filter tank 1 through the spiral pipe 31 to avoid the accumulation of rainwater impurities at the edge of the natural filter tank 1. When the amount of rainwater is small, the water flow will not cause too much impact force on the through-hole baffle 33 on the flow hole. Therefore, when the rainwater passes through, the outer flow hole is in a closed state; when the amount of rainwater is large, the rainwater causes a certain impact on the through-hole baffle 33 on the surface of the flow hole, causing the through-hole baffle 33 to slide inside the spiral pipe 31, and the flow hole covered by the through-hole baffle 33 is opened, and the reset spring 32 will be compressed at this time. After the amount of rainwater decreases, the impact force of rainwater on the through-hole baffle 33 is less than the elastic force of the reset spring 32, so the reset spring 32 is reset, so that the through-hole baffle 33 covers the flow hole again, and then the rainwater completes the preliminary filtration through the natural filtration tank 1 to reach the perforated pipe 41. When the amount of rainwater is large, the rainwater can flow along the water flow to a suitable position and then be pumped out to the water treatment mechanism 5 through a pump. When the amount of rainwater is small, the lifting hydraulic cylinder 45 is started to lift the closed end of the perforated pipe 41. At this time, the fixed buckle 43 and the rotating shaft 44 rotate relative to each other, and the rainwater can flow to a suitable position. Then the rainwater is filtered for the second time, and the degree of filtration required for rainwater is determined according to different needs. If purer rainwater is needed, the rainwater is discharged after double filtration through the inner filter screen 54 and the outer filter screen 55; if the required purity of rainwater is not very high, the rainwater flows out through the split filter screen to the first conducting pipe 56.
