Description

TECHNICAL FIELD

[0001] The present application relates to the field of rainwater collection irrigation, in particular to a rainwater collection irrigation device for garden ecological greening. BACKGROUND

[0002] In some garden scenes, due to building structure restrictions or landscape planning requirements, it is difficult to fixedly set rainwater collection irrigation devices on the roof, so small collection irrigation devices are often used as a substitute. However, in the actual collection process, if the collection surface is set to a low height, although it is convenient to install, it is easy to cause fallen leaves, debris and the like to flow into the collection system with the rainwater, increasing the difficulty of subsequent filtration and purification; if the collection surface height is raised to avoid the entry of debris, the space above the plants will be blocked to some extent, affecting the direct irrigation effect of natural precipitation on the plants, and thus possibly interfering with the normal growth rhythm of the plants and the natural water circulation process of the ecological environment.

[0003] This contradiction in height setting makes small collection irrigation devices face double challenges in technology and design when considering the needs of debris interception and natural irrigation, so it can be seen that the existing rainwater collection irrigation device still has a large room for improvement. SUMMARY

[0004] The purpose of the present application is to solve the problem in the prior art that it is difficult to simultaneously consider debris interception and natural irrigation, and a rainwater collection irrigation device for garden ecological greening is provided.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows: a rainwater collection irrigation device for garden ecological greening, comprising a base, a drain pipe is fixedly connected to the side wall of the base, a top opening is formed in the top of the base, and further comprising:

[0006] a collection box, the collection box is arranged directly above the base, a plurality of electric push rods are fixed between the collection box and the base, a collection opening is formed in the top of the collection box, and a drain opening is formed in the bottom of the collection box;

[0007] a plurality of guide plates, the guide plates are arranged on one side of the collection opening, an adjusting assembly is arranged on the collection box, and the adjusting assembly is used to adjust the overturning angle of the guide plates;

[0008] a guide groove, the guide groove is formed on the surface of the guide plate;

[0009] a guide hole, the guide hole is formed between adjacent guide grooves.

[0010] Specifically, in use, the base is installed in the low tree area in the garden, the collecting box is raised by starting the electric push rod, the collecting box is moved to the position above the tree, the fallen leaves and other sundries of the tree are prevented from entering the inside of the collecting box to cause blockage, the guide plates are adjusted to the two sides of the collecting box by the adjusting assembly to expand the collecting range of the collecting box.

[0011] Since the guide plates are turned over, the natural irrigation of rainwater is blocked, the guide groove and the guide hole are formed on the guide plate, when the rainwater enters the guide groove, the rainwater flows downward along the guide groove and enters the inside of the collecting box, when the rainwater enters the guide hole, the rainwater passes through the guide plate along the guide hole and flows to the blocked area below the guide plate to perform natural irrigation on the blocked area below the guide plate.

[0012] In summary, the scheme reduces the problem of fallen leaves blockage by the raising effect, and also ensures that the rainwater enters the blocked area below the guide plate to complete natural irrigation.

[0013] It should be noted that the rainwater flows from the collecting box to the inside of the base through the drain port, and the drain pipe of the base is connected with the irrigation pipeline.

[0014] Preferably, a rain cover is fixed on the bottom surface of the collecting box and is sleeved on the outside of the base.

[0015] Specifically, rain weather is often accompanied by strong wind, under the action of wind force, the originally vertically falling rainwater will present a skewed state of floating, at this time, since the base exists, the plants on the leeward side of the base will greatly reduce the contact opportunity with the rainwater due to the blocking effect of the base, in addition, considering that there is a ventilation space between the base and the collecting box, the rainwater falling along the guide hole on the leeward side of the collecting box will also be skewed due to the action of wind force and away from the plants on the leeward side of the base, thereby causing the plants on the leeward side of the collecting box to be difficult to obtain uniform natural irrigation, therefore, the rain cover is arranged to effectively block the ventilation space between the base and the collecting box, so as to significantly reduce the influence of wind force on the leeward side of the base, thereby better guaranteeing that the plants on the leeward side can be irrigated with relatively uniform rainwater.

[0016] Preferably, inclined holes are formed on the surface of the rain cover, a windproof cylinder is arranged in the rain cover, and the windproof cylinder is fixed on the bottom surface of the collecting box.

[0017] Specifically, under the action of wind, if the inclined rain directly hits the surface of the rain shield and flows along the surface of the rain shield into the soil, it may cause the soil near the base to have excessive water content, resulting in soft soil and affecting the stability of the base. The inclined hole is arranged on the surface of the rain shield, rain can enter the inside of the rain shield through the inclined hole, and flow along the inner wall of the rain shield to the inside of the base for collection. On the one hand, it can avoid rain directly entering the soil, causing the soil to be soft, and ensuring the stability of the base. On the other hand, it can also increase the collection area of the device and ensure the collection efficiency.

[0018] Further, by arranging the wind shield in the collecting box, the airflow can also avoid passing through the rain shield to affect the natural irrigation effect of the leeward surface.

[0019] Preferably, the flow guide hole is fixed with a flow guide block, the middle part of the flow guide block is provided with a guide groove, and the guide groove is rotatably connected with a rotating ball. The inside of the rotating ball is provided with a water permeable hole penetrating up and down.

[0020] Specifically, since the guide plate is in an inclined state, when the rainwater falls along the flow guide hole, part of the rainwater will flow along the surface of the guide plate under the action of gravity due to the inclination angle and smoothness of the surface of the guide plate, rather than all falling vertically through the flow guide hole. In this case, the flow of rainwater on the surface of the guide plate may cause the rainwater to converge into a stream or flow along a specific trajectory, resulting in a relatively concentrated dropping position of the rainwater in the shielding area below the guide plate, making it difficult to form an uniform dropping effect, and further causing the plants in this area to be unable to uniformly receive rainwater irrigation. The present application guides the rainwater by arranging a flow guide block in the flow guide hole, so that it can enter the water permeable hole in the rotating ball and fall along the water permeable hole. Since the rotating ball adopts an asymmetric mass distribution design, for example, a high-density metal counterweight block is embedded at the bottom, and a lightweight engineering plastic is used at the top. This design allows the rotating ball to always maintain a stable posture with the bottom facing down when subjected to gravity, even if the guide plate is turned over. The water permeable hole in the rotating ball can also maintain a vertical state. Since the rotating ball is spherical, the surface around the water permeable hole on the rotating ball is higher than the bottom of the water permeable hole, forming a funnel-like closing structure. Therefore, it can ensure that the rainwater entering the water permeable hole is not affected by the inclination angle of the guide plate, and always maintains a vertical falling state, thereby ensuring the uniformity of the rainwater dropping in the shielding area below the guide plate.

[0021] Preferably, the adjusting assembly comprises a rotating shaft fixed on the side wall of the guide plate, a driving sleeve rotatably sleeved outside the rotating shaft, an installation groove arranged on the surface of the driving sleeve, a push pin inserted in the installation groove, the push pin being fixed on the rotating shaft, a spring fixed between the push pin and the inner wall of the installation groove, the driving sleeve being rotatably connected to the side wall of the collecting box, an electric motor fixed on the outer wall of the collecting box, and the output shaft of the electric motor being fixedly connected with the driving sleeve.

[0022] Preferably, the water-permeable hole is internally fixed with an air bag ring, the inside of the guide plate is inserted with a flow guide pipe, a plurality of branch pipes are fixedly communicated on the side wall of the flow guide pipe, the branch pipes are respectively communicated with the inside of the corresponding air bag ring, and an inflation and suction assembly is arranged at the end of the flow guide pipe.

[0023] Preferably, the inflation and suction assembly comprises a displacement slot, the displacement slot is arranged on the side wall of the guide plate, a moving rod is slidably connected in the displacement slot, a plurality of push plugs are fixed on the moving rod, the push plugs are inserted in the corresponding flow guide pipes, an elastic push rod is arranged on one side of the moving rod, the fixed end of the elastic push rod is fixed on the side wall of the guide plate, the movable end of the elastic push rod is fixed with the moving rod, a cam is arranged on the other side of the moving rod, and the cam is fixed on the driving sleeve.

[0024] Preferably, an elastic film is fixed on the inner wall of the air bag ring, a plurality of protrusions are fixed on the surface of the elastic film, a through hole is arranged on the surface of the elastic film, and the inner diameter of the through hole is smaller than the inner diameter of the branch pipe.

[0025] Preferably, a groove is arranged on the inner wall of the mounting groove, the groove is arranged at one end of the push pin, and a friction plate is fixed in the groove.

[0026] Preferably, an overflow hole is arranged on the side wall of the flow guide hole, and the overflow hole is communicated with the inside of the flow guide groove.

[0027] Compared with the prior art, the present application has the following beneficial effects:

[0028] Firstly, the flow guide groove and the flow guide hole are arranged on the guide plate, when the rainwater enters the flow guide groove, it can flow downward along the flow guide groove and enter the inside of the collecting box, and when the rainwater enters the flow guide hole, it can pass through the guide plate along the flow guide hole and flow to the shielding area below the guide plate, so that the shielding area of the guide plate is naturally irrigated.

[0029] Secondly, the inclined holes are arranged on the surface of the rain shield, the rainwater can enter the inside of the rain shield through the inclined holes and flow along the inner wall of the rain shield to the inside of the base, on the one hand, the rainwater can be prevented from directly entering the soil to cause the soil to be soft, so that the stability of the base is ensured, and on the other hand, the collecting area of the device can be increased, and the collecting efficiency is ensured.

[0030] Thirdly, the application sets a guide block in the guide hole to guide the rainwater to enter the water-permeable hole in the rotating ball and fall along the water-permeable hole. Since the rotating ball is designed with asymmetric mass distribution, for example, the bottom is embedded with a high-density metal counterweight and the top is made of light engineering plastic, the design makes the rotating ball always keep a stable posture with the bottom down when it is affected by gravity. Even if the guide plate is turned over, the water-permeable hole in the rotating ball can also maintain a vertical state. Since the rotating ball is spherical, the surface around the water-permeable hole on the rotating ball is higher than the bottom of the water-permeable hole, forming a funnel-like closing structure, so as to ensure that the rainwater entering the water-permeable hole is not affected by the inclination angle of the guide plate and always keeps a vertical falling state, thereby ensuring the uniformity of the rainwater dripping in the shielding area below the guide plate.

[0042] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0043] like Figures 1 to 10 The illustrated rainwater harvesting and irrigation device for landscaping includes a base 1, a drain pipe 2 fixedly connected to the side wall of the base 1, and a top opening 3 on the top of the base 1. It also includes:

[0044] Collection box 4 is located directly above base 1. Multiple electric push rods 5 are fixed between collection box 4 and base 1. Collection box 4 has a collection port 6 on top and a drain port 7 on bottom.

[0045] Guide plates 8, there are multiple guide plates 8, the guide plates 8 are arranged on one side of the collection port 6, and the collection box 4 is provided with an adjustment component, which is used to adjust the flip angle of the guide plates 8;

[0046] The flow guide 9 is formed on the surface of the guide plate 8;

[0047] The flow guide hole 10 is formed between adjacent flow guide grooves 9.

[0048] Specifically, when in use, the base 1 is installed in the low-lying tree area of ​​the garden. By activating the electric push rod 5, the collection box 4 can be raised, so that the collection box 4 is moved to a position above the trees, preventing fallen leaves and other debris from entering the collection box 4 and causing blockage. Then, by adjusting the guide plate 8, the collection box 4 can be flipped to both sides to expand the collection range of the collection box 4.

[0049] Since the guide plate 8 will block the natural irrigation of rainwater after it is flipped, the present invention provides a guide groove 9 and a guide hole 10 on the guide plate 8. When rainwater enters the guide groove 9, it can flow downward along the guide groove 9 and enter the collection box 4. When rainwater enters the guide hole 10, it can pass through the guide plate 8 along the guide hole 10 and flow to the blocked area below the guide plate 8 to provide natural irrigation to the area blocked by the guide plate 8.

[0050] In summary, this solution reduces the problem of fallen leaves clogging the area by raising the water level, while also ensuring that rainwater enters the shaded area below the guide plate 8 to complete natural irrigation.

[0051] It should be noted that after the rainwater enters the collection box 4, it flows from the drain outlet 7 into the interior of the base 1, and the drain pipe 2 of the base 1 is connected to the irrigation pipe.

[0052] As a further embodiment of the present invention, a rain cover 11 is fixed on the bottom surface of the collection box 4, and the rain cover 11 is sleeved on the outside of the base 1.

[0053] Specifically, rainy weather is often accompanied by strong winds. Under the influence of the wind, rainwater that originally falls vertically will drift at an angle. At this time, due to the presence of the base 1, the plants on the leeward side will have significantly reduced contact with rainwater due to the shielding effect of the base 1. In addition, considering that there is a ventilation space between the base 1 and the collection box 4, the rainwater falling along the guide hole 10 on the leeward side of the collection box 4 will also be tilted by the wind, moving away from the plants on the leeward side of the base 1. As a result, the plants on the leeward side of the collection box 4 will have difficulty receiving even natural irrigation. Therefore, this invention provides a rain cover 11 to effectively shield the ventilation space between the base 1 and the collection box 4, thereby significantly reducing the impact of wind on the leeward side of the base 1, and thus better ensuring that the plants on the leeward side receive more even rainwater irrigation.

[0054] As a further embodiment of the present invention, the surface of the rain cover 11 is provided with an oblique hole 12, and a windproof tube 13 is provided inside the rain cover 11, and the windproof tube 13 is fixed to the bottom surface of the collection box 4.

[0055] Specifically, under the action of wind, if oblique rainwater directly hits the surface of the rain cover 11 and flows down the surface of the rain cover 11 into the soil, it may cause the soil near the base 1 to have excessive moisture content, resulting in loose soil and affecting the stability of the base 1. The present invention opens oblique holes 12 on the surface of the rain cover 11, so that rainwater can enter the interior of the rain cover 11 through the oblique holes 12 and flow down the inner wall of the rain cover 11 into the interior of the base 1 for collection. On the one hand, it can prevent rainwater from directly entering the soil and causing the soil to become loose, thus ensuring the stability of the base 1. On the other hand, it can also increase the collection area of ​​the device and ensure collection efficiency.

[0056] Furthermore, by setting a windbreak 13 inside the collection box 4, airflow can be prevented from passing through the rain cover 11 and affecting the natural irrigation effect on its leeward side.

[0057] As a further embodiment of the present invention, a guide block 14 is fixed inside the guide hole 10, a guide groove 15 is provided in the middle of the guide block 14, a rotating ball 16 is rotatably connected inside the guide groove 15, and a water-permeable hole 17 is provided inside the rotating ball 16.

[0058] Specifically, because the guide plate 8 is tilted, when rainwater falls along the guide hole 10, some of the rainwater will flow along the surface of the guide plate 8 under the influence of gravity due to the tilt angle and surface smoothness of the guide plate 8, instead of dripping vertically through the guide hole 10. In this case, the flow of rainwater on the surface of the guide plate 8 may cause the rainwater to converge into streams or flow along a specific trajectory, resulting in a relatively concentrated dripping position in the shaded area below the guide plate 8, making it difficult to form a uniform dripping effect. Consequently, the plants in this area may not receive rainwater irrigation evenly. This invention provides a guide block 14 inside the guide hole 10 to guide the rainwater into the permeable hole 17 inside the rotating ball 16, allowing it to flow along the permeable hole 17. As the rotating ball 16 adopts an asymmetrical mass distribution design, for example, a high-density metal counterweight is embedded at the bottom while a lightweight engineering plastic is used at the top. This design ensures that the rotating ball 16 maintains a stable bottom-down posture when subjected to gravity. Even if the guide plate 8 flips over, the water-permeable holes 17 inside the rotating ball 16 can remain vertical. Furthermore, since the rotating ball 16 is spherical, the surrounding surfaces of the water-permeable holes 17 are all higher than the bottom opening of the water-permeable holes 17, forming a funnel-like constricted structure. This ensures that after rainwater enters the water-permeable holes 17, it is not affected by the tilt angle of the guide plate 8 and always maintains a vertical falling state, thereby ensuring the uniformity of rainwater dripping in the area shielded below the guide plate 8.

[0059] As a further embodiment of the present invention, the adjustment assembly includes a rotating shaft 18, which is fixed on the side wall of the guide plate 8. A drive sleeve 19 is rotatably sleeved on the outside of the rotating shaft 18. An installation groove 20 is opened on the surface of the drive sleeve 19. A push pin 21 is inserted into the installation groove 20 and fixed on the rotating shaft 18. A spring 22 is fixed between the push pin 21 and the inner wall of the installation groove 20. The drive sleeve 19 is rotatably connected to the side wall of the collection box 4. A motor 23 is fixed on the outer wall of the collection box 4. The output shaft of the motor 23 is fixedly connected to the drive sleeve 19.

[0060] Specifically, the drive sleeve 19 is driven to rotate by the drive component. When the drive sleeve 19 rotates in the forward direction, it drives the push pin 21 to move through the inner wall of the mounting groove 20. The push pin 21 drives the rotating shaft 18 to rotate, thereby causing the guide plate 8 to flip in the forward direction. When the drive sleeve 19 rotates in the reverse direction, the inner wall of the mounting groove 20 moves away from the push pin 21. Under the gravity of the guide plate 8, the rotating shaft 18 and the push pin 21 can be automatically driven to move with the mounting groove 20, thereby completing the reverse flipping of the guide plate 8.

[0061] Furthermore, in windy weather, when the guide plate 8 is on the windward side, the wind will push the guide plate 8 to rotate in the forward direction, thereby driving the push pin 21 to compress the spring 22 and rotate to make room. When the wind force decreases, the push pin 21 will be pushed back to its original position under the pushing action of the spring 22, thereby driving the rotating shaft 18 and the guide plate 8 to return to their original position. The guide plate 8 is provided with a certain range of rotation and clearance space, mainly to give the guide plate 8 the ability to adapt to external forces in windy environments. When strong winds act on the guide plate 8, the guide plate 8 can rotate and move smoothly within the preset rotation and clearance space. This design can effectively alleviate the direct impact of wind on the guide plate 8 and prevent the guide plate 8 from being structurally damaged or deformed due to excessive wind force.

[0062] Furthermore, a pressure sensor can be installed to detect the compressive force of the spring 22. When the compressive force reaches a preset value, the guide plate 8 is driven to flip to a horizontal state, further reducing damage.

[0063] As a further embodiment of the present invention, an airbag ring 24 is fixed inside the water-permeable hole 17, and a guide tube 25 is inserted inside the guide plate 8. Multiple branch pipes 26 are fixedly connected to the side wall of the guide tube 25. The branch pipes 26 are respectively connected to the interior of the corresponding airbag ring 24. An inflation and suction assembly is provided at the end of the guide tube 25. When the guide plate 8 is located on the windward side, the inflation and suction assembly inflates the airbag ring 24, reducing the water-guiding channel of the airbag ring 24.

[0064] Specifically, due to the force of wind, rainwater often falls at an angle. When rainwater falls on the windward side of the device, it directly enters the shielded area of ​​the guide plate 8 along the angle of inclination. At this time, the guide holes 10 on the guide plate 8 are still continuously draining water, which can easily lead to excessive rainwater being poured on the windward side of the device, causing problems such as local water accumulation. To solve this problem, the present invention sets an airbag ring 24 inside the guide hole 10. Under normal conditions, the airbag ring 24 is installed inside the guide hole 10, and its central part has a guide channel for rainwater to flow. Rainwater can flow downward from the guide channel to achieve normal drainage function. When the guide plate 8 is on the windward side, the device's charging and suction components will start working, inflating the guide pipe 25 with air. The gas enters the interior of each airbag ring 24 through each branch pipe 26, causing each airbag ring 24 to inflate and expand, thereby narrowing the guide channel in the central part of the airbag ring 24, thus effectively reducing the amount of rainwater poured on the windward side and avoiding excessive rainwater pouring.

[0065] It should be noted that the branch tube 26 is rotatably connected to the rotating ball 16, and the branch tube 26 is connected to the airbag ring 24 after being inserted into the rotating ball 16.

[0066] As a further embodiment of the present invention, the filling and suction assembly includes a relief groove 27, which is formed on the side wall of the guide plate 8. A movable rod 28 is slidably connected inside the relief groove 27. A plurality of push plugs 29 are fixed on the movable rod 28 and inserted into the corresponding guide tube 25. An elastic push rod 30 is provided on one side of the movable rod 28. The fixed end of the elastic push rod 30 is fixed on the side wall of the guide plate 8, and the movable end of the elastic push rod 30 is fixed to the movable rod 28. A cam 31 is provided on the other side of the movable rod 28 and is fixed on the drive sleeve 19.

[0067] Specifically, during the process of the wind-driven guide plate 8 flipping, the guide plate 8 drives the moving rod 28 to move. The moving rod 28 slides on the surface of the cam 31. Under the pushing action of the cam 31, the moving rod 28 drives the push plug 29 to move inside the guide tube 25, thereby pushing the gas inside the guide tube 25 into the branch tube 26 and into the airbag ring 24 along the branch tube 26, thus completing the inflation function of the airbag ring 24.

[0068] During the movement of the moving rod 28, the elastic push rod 30 is compressed. When the wind force decreases and the guide plate 8 is reset, the elastic push rod 30 can push the moving rod 28 and the push plug 29 to reset, thus completing the air intake function.

[0069] As a further embodiment of the present invention, an elastic film 32 is fixed on the inner wall of the airbag ring 24, a plurality of protrusions 33 are fixed on the surface of the elastic film 32, and a through hole 34 is opened on the surface of the elastic film 32, the inner diameter of the through hole 34 being smaller than the inner diameter of the branch pipe 26.

[0070] Specifically, although the design of raising the collection box 4 can effectively reduce the probability of larger impurities such as leaves entering the collection box 4, fine impurities such as dust and spores mixed in with rainwater may still adhere to the inner ring surface of the airbag ring 24. Over time, this can easily lead to blockage of the flow channel. To solve this problem, the present invention sets an elastic membrane 32 inside the airbag ring 24, dividing the interior of the airbag ring 24 into a first chamber and a second chamber. In the initial stage of inflation, gas first enters the first chamber. As gas is continuously injected, the gas pressure in the first chamber gradually increases. When the gas pressure inside the first chamber is greater than that in the second chamber, the elastic membrane... Under the action of pressure difference, 32 bends towards the second chamber. Since multiple protrusions 33 are pre-set on the surface of the elastic film 32, the corresponding position on the outer surface of the airbag ring 24 becomes convex under the push of the protrusions 33, so that the surface of the entire airbag ring 24 changes from the original smooth state to an uneven state. When the surface of the airbag ring 24 changes from smooth to uneven, its surface curvature undergoes a significant abrupt change. The impurities originally attached to the surface will be subjected to uneven mechanical stress due to the change in surface shape. This change in stress distribution can effectively destroy the adhesion between the impurities and the surface of the airbag ring 24, causing the impurities to detach from the surface.

[0071] It should be noted that during the initial inflation phase, some gas will slowly enter the second chamber through the through-hole 34 on the surface of the elastic membrane 32, causing the air pressure in the second chamber to gradually increase. However, since the aperture of the through-hole 34 is designed to be small, the gas flow rate is relatively slow. Therefore, the air pressure in the first chamber is always higher than that in the second chamber, thus maintaining the tendency of the elastic membrane 32 to bulge towards the second chamber and ensuring that the uneven state of the surface of the airbag ring 24 is maintained.

[0072] Once the air intake process is initiated and reset, the airbag ring 24 will return to a flat surface. This flat surface reduces the resistance when rainwater passes through, ensuring that the efficiency of the natural irrigation process is not affected.

[0073] As a further embodiment of the present invention, a groove 35 is provided on the inner wall of the mounting groove 20, the groove 35 is disposed at one end of the push pin 21, and a friction plate 36 is fixed in the groove 35.

[0074] Specifically, the friction plate 36 is made of elastic material with a rough surface. During the movement of the push pin 21, its contact with the friction plate 36 increases frictional resistance, thereby limiting the movement speed of the push pin 21. This invention places the friction plate 36 at the end of the push pin 21's movement trajectory. This design ensures that the push pin 21 does not contact the friction plate 36 in the initial stage of movement. Only after the guide plate 8 has rotated a certain distance will the push pin 21 be obstructed by the friction plate 36. Thus, during the inflation process, in the initial stage, due to the relatively high rotation speed of the guide plate 8... It can inflate quickly, causing the elastic diaphragm to rapidly bulge 33. The instantaneous pressure change triggers a slight vibration on the surface of the airbag ring 24, initially loosening the impurities attached to the surface. As the push pin 21 contacts the friction plate 36, the moving speed of the guide plate 8 gradually decreases, and the inflation speed also slows down. At this time, the bulge 33 of the diaphragm is maintained with stable pressure, keeping the surface of the airbag ring 24 in an uneven structure. Then, by utilizing the continuous surface deformation and the turbulence effect generated when rainwater flows through, the impurities are further washed away, achieving a more thorough cleaning effect.

[0075] As a further embodiment of the present invention, an overflow hole 37 is provided on the side wall of the guide hole 10, and the overflow hole 37 is in communication with the interior of the guide groove 9.

[0076] Specifically, during the inflation and expansion of the airbag ring 24 and the reduction of the flow channel, the cross-sectional area of ​​the flow channel decreases accordingly, and the resistance to rainwater flow increases significantly, causing the rainwater discharge speed to gradually slow down. When rainwater continues to fall into the flow hole 10, and the discharge speed cannot match the inflow speed, the rainwater in the flow hole 10 will gradually accumulate, and may even become full. At this time, the excess rainwater is likely to overflow from the edge of the flow hole 10. To solve this problem, the present invention opens an overflow hole 37 on the side wall of the flow hole 10. The overflow hole 37 is connected to the flow channel 9 on the guide plate 8. When the rainwater in the flow hole 10 is full, the excess rainwater can immediately overflow from the overflow hole 37 and flow along the preset channel to the flow channel 9, thereby avoiding the waste of rainwater caused by water overflow.
