Description

Technical Field

[0001] The present invention relates to the field of rainwater collection and irrigation, and in particular to a rainwater collection and irrigation device for garden ecological greening. Background Art

[0002] In some garden settings, due to structural limitations or landscape planning requirements, it's difficult to install fixed rainwater collection and irrigation systems on rooftops. Therefore, multi-point, small-scale collection and irrigation systems are often used as an alternative. However, in actual collection, if the collection surface is set at a low height, while it facilitates installation, it can easily cause fallen leaves and debris to flow into the collection system with rainwater, increasing the difficulty of subsequent filtration and purification. Raising the collection surface to prevent debris from entering will, to a certain extent, block the space above the plants, affecting the direct watering effect of natural precipitation on the plants, and potentially interfering with the normal growth rhythm of the plants and the natural water cycle of the ecological environment.

[0003] This contradiction in height setting makes small-scale collection and irrigation devices face dual challenges in technology and design when taking into account both debris interception and natural irrigation needs. It can be seen that the existing rainwater collection and irrigation devices still have a lot of room for improvement. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that it is difficult to take into account both debris interception and natural irrigation at the same time, and to propose a rainwater collection and irrigation device for garden ecological greening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rainwater collection and irrigation device for garden ecological greening, comprising a base, a side wall of the base being fixedly connected to a drainage pipe, a top opening being opened on the top of the base, and further comprising:

[0006] A collection box is provided directly above the base, a plurality of electric push rods are fixed between the collection box and the base, a collection port is provided at the top of the collection box, and a drainage port is provided at the bottom of the collection box;

[0007] A guide plate, wherein the guide plate is provided in plurality and is arranged on one side of the collection port. The collection box is provided with an adjustment component for adjusting the flip angle of the guide plate;

[0008] A guide groove, wherein the guide groove is provided on the surface of the guide plate;

[0009] The guide holes are opened between adjacent guide grooves.

[0010] Specifically, when in use, the base is installed in the low tree area in the garden. By starting the electric push rod, the collection box can be raised and moved to a position above the tree to prevent debris such as fallen leaves from the tree from entering the collection box and causing blockage. Then, the guide plate is adjusted to flip to both sides of the collection box by adjusting the assembly to expand the collection range of the collection box.

[0011] Since the guide plate will block the natural irrigation of rainwater after it is turned over, the present invention provides a guide groove and a guide hole on the guide plate. When rainwater enters the guide groove, it can flow downward along the guide groove and enter the collection box. When rainwater enters the guide hole, it can pass through the guide plate along the guide hole and flow to the blocked area below the guide plate, thereby naturally irrigating the area blocked by the guide plate.

[0012] In summary, this solution reduces the problem of leaf blockage by raising the plate, while also ensuring that rainwater enters the shielded area below the guide plate, completing natural irrigation.

[0013] It should be noted that after rainwater enters the collection box, it flows from the drain outlet to the inside of the base, and the drain pipe of the base is connected to the irrigation pipe.

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

[0015] Specifically, rainy weather is often accompanied by strong winds. Under the action of wind, the rainwater that originally fell vertically will fall in a skewed state. At this time, due to the existence of the base, the plants on the leeward side will have a greatly reduced chance of contact with rainwater due to the shielding effect of the base. In addition, considering that there is a ventilation space between the base and the collection box, the rainwater falling along the diversion hole on the leeward side of the collection box will also be skewed due to the action of wind, away from the plants on the leeward side of the base, thereby making it difficult for the plants on the leeward side of the collection box to obtain uniform natural irrigation. Therefore, the present invention effectively blocks the ventilation space between the base and the collection box by providing a rain shield, so as to significantly reduce the impact of wind on the leeward side of the base, thereby better ensuring that the plants on the leeward side can obtain more uniform rainwater irrigation.

[0016] Preferably, an oblique hole is opened on the surface of the rain shield, a windshield is provided inside the rain shield, and the windshield is fixed on the bottom surface of the collection box.

[0017] Specifically, under the action of wind, if the skewed rainwater directly hits the surface of the rain shield and flows down along the surface of the rain shield into the soil, it may cause the soil near the base to have excessive water content, making the soil loose and affecting the stability of the base. The present invention provides inclined holes on the surface of the rain shield, so that rainwater can enter the interior of the rain shield through the inclined holes and flow along the inner wall of the rain shield to the interior of the base for collection. On the one hand, it can prevent rainwater from directly entering the soil and causing the soil to become loose, thereby ensuring the stability of the base. On the other hand, it can also increase the collection area of ​​the device and ensure collection efficiency.

[0018] Furthermore, by providing a windshield in the collection box, it is also possible to prevent airflow from passing through the rain shield and affecting the natural irrigation effect of the leeward side.

[0019] Preferably, a guide block is fixed in the guide hole, a guide groove is provided in the middle of the guide block, a rotating ball is rotatably connected in the guide groove, and a water-permeable hole is provided in the rotating ball which passes through from top to bottom.

[0020] Specifically, since the guide plate is in an inclined state, when rainwater falls along the diversion 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 surface smoothness of the guide plate, rather than all of it dripping vertically through the diversion hole. In this case, the flow of rainwater on the surface of the guide plate may cause the rainwater to gather into streams or flow along a specific trajectory, resulting in the rainwater dripping position in the shielded area below the guide plate being relatively concentrated, making it difficult to form a uniform dripping effect, which may make it impossible for plants in the area to receive rainwater irrigation uniformly. The present invention provides a diversion block in the diversion hole to guide the rainwater so that it can enter the water-permeable hole in the rotating ball and flow along the water-permeable hole. The hole falls, because the rotating ball adopts an asymmetric mass distribution design, for example, a high-density metal counterweight is embedded in the bottom, and a lightweight engineering plastic is used on 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 flips over, the water permeable holes in the rotating ball can maintain a vertical state. Moreover, since the rotating ball is spherical, the surfaces of the water permeable holes on the rotating ball are all higher than the bottom of the water permeable holes, forming a funnel-like closing structure, which can ensure that after rainwater enters the water permeable holes, it will not be affected by the inclination angle of the guide plate and will always maintain a vertical falling state, thereby ensuring the uniformity of rainwater dripping in the shielded area below the guide plate.

[0021] Preferably, the adjusting assembly includes a rotating shaft, which is fixed on the side wall of the guide plate, and a driving sleeve is provided on the rotating sleeve outside the rotating shaft. A mounting groove is provided on the surface of the driving sleeve, and a pushing pin is inserted into the mounting groove. The pushing pin is fixed on the rotating shaft, and a spring is fixed between the pushing pin and the inner wall of the mounting groove. The driving sleeve is rotatably connected to the side wall of the collection box, and a motor is fixed on the outer wall of the collection box, and the output shaft of the motor is fixedly connected to the driving sleeve.

[0022] Preferably, an airbag ring is fixed in the water-permeable hole, a guide tube is inserted into the interior of the guide plate, a plurality of branch tubes are fixedly connected on the side wall of the guide tube, and the branch tubes are respectively connected to the interior of the corresponding airbag ring. An inflation and suction component is provided at the end of the guide tube. When the guide plate is located on the windward side, the inflation and suction component inflates the airbag ring to reduce the water guide channel of the airbag ring.

[0023] Preferably, the charging and suction assembly includes a giveway groove, which is opened on the side wall of the guide plate, and a moving rod is slidably connected to the inside of the giveway groove. A plurality of push plugs are fixed on the moving rod, and the push plugs are inserted into the corresponding guide tubes. An elastic push rod is provided on one side of the moving rod, and 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 to the moving rod, and a cam is provided 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 airbag ring, a plurality of protrusions are fixed on the surface of the elastic film, a through hole is opened 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 provided on the inner wall of the mounting slot, the groove is provided at one end of the pushing pin, and a friction plate is fixed in the groove.

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

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

[0028] 1. The present invention provides a guide groove and a guide hole on the guide plate. When rainwater enters the guide groove, it can flow downward along the guide groove and enter the collection box. After entering the guide hole, the rainwater can pass through the guide plate along the guide hole and flow to the shielded area below the guide plate, thereby naturally irrigating the area shielded by the guide plate.

[0029] 2. The present invention provides inclined holes on the surface of the rain shield, so that rainwater can enter the interior of the rain shield through the inclined holes and flow along the inner wall of the rain shield to the inside of the base for collection. On the one hand, it can prevent rainwater from directly entering the soil, causing the soil to become loose, thereby 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.

[0030] 3. The present invention provides a guide block within the guide hole to guide rainwater so that it enters the water-permeable hole in the rotating ball and falls along the water-permeable hole. Since the rotating ball adopts an asymmetric mass distribution design, for example, a high-density metal counterweight is embedded in the bottom and a lightweight engineering plastic is used on the top, this design ensures that the rotating ball always maintains a stable bottom-down posture when subjected to gravity. Even if the guide plate flips, the water-permeable hole in the rotating ball can remain in a vertical state. Moreover, since the rotating ball is spherical, the surrounding surfaces of the water-permeable hole on the rotating ball are all higher than the bottom of the water-permeable hole, forming a funnel-like closing structure. This ensures that after entering the water-permeable hole, rainwater will not be affected by the inclination angle of the guide plate and will always maintain a vertical falling state, thereby ensuring that rainwater drips evenly in the shielded area below the guide plate.

DETAILED DESCRIPTION

[0042] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0043] like Figures 1 to 10 The rainwater collection and irrigation device for garden ecological greening shown in the figure includes a base 1, a drainage pipe 2 is fixedly connected to the side wall of the base 1, a top opening 3 is opened on the top of the base 1, and further includes:

[0044] The collecting box 4 is arranged just above the base 1. A plurality of electric push rods 5 are fixed between the collecting box 4 and the base 1. A collecting port 6 is provided at the top of the collecting box 4, and a drain port 7 is provided at the bottom of the collecting box 4.

[0045] A plurality of guide plates 8 are provided, each of which is disposed on one side of the collecting port 6. The collecting box 4 is provided with an adjustment component for adjusting the flip angle of the guide plate 8.

[0046] A guide groove 9 is provided on the surface of the guide plate 8;

[0047] The guide holes 10 are opened between adjacent guide grooves 9 .

[0048] Specifically, when in use, the base 1 is installed in a low tree area in a garden. By starting 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 tree, thereby preventing debris such as fallen leaves from the tree from entering the collection box 4 and causing blockage. Then, the guide plate 8 is adjusted by the adjustment component to flip to both sides of the collection box 4, thereby expanding the collection range of the collection box 4.

[0049] Since the guide plate 8 is turned over, it will block the natural irrigation of rainwater. In the present invention, a guide groove 9 and a guide hole 10 are opened on the guide plate 8. When rainwater enters the guide groove 9, it can flow downward along the guide groove 9 and enter the interior of the collection box 4. When the 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, thereby naturally irrigating the area blocked by the guide plate 8.

[0050] In summary, this solution reduces the problem of leaf blockage by raising the water level, and at the same time ensures that rainwater enters the shielded area below the guide plate 8, completing natural irrigation.

[0051] It should be noted that after rainwater enters the collection box 4, it flows from the drain port 7 to the inside 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 shield 11 is fixed on the bottom surface of the collection box 4 , and the rain shield 11 is sleeved on the outer side of the base 1 .

[0053] Specifically, rainy weather is often accompanied by strong winds. Under the action of wind, the rainwater that originally fell vertically will fall in a skewed state. At this time, due to the existence of the base 1, the plants on the leeward side will have a greatly reduced chance of 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 skewed due to the action of wind, away from the plants on the leeward side of the base 1, thereby making it difficult for the plants on the leeward side of the collection box 4 to obtain uniform natural irrigation. Therefore, the present invention effectively blocks the ventilation space between the base 1 and the collection box 4 by providing a rain shield 11, thereby significantly reducing the impact of wind on the leeward side of the base 1, thereby better ensuring that the plants on the leeward side can obtain more uniform rainwater irrigation.

[0054] As a further embodiment of the present invention, an oblique hole 12 is opened on the surface of the rain shield 11 , and a windshield 13 is provided inside the rain shield 11 . The windshield 13 is fixed to the bottom surface of the collection box 4 .

[0055] Specifically, under the action of wind, if skewed rainwater directly hits the surface of the rain shield 11 and flows downward along the surface of the rain shield 11 into the soil, it may cause the soil near the base 1 to have excessive water content, resulting in loose soil and affecting the stability of the base 1. The present invention provides an inclined hole 12 on the surface of the rain shield 11, so that rainwater can enter the interior of the rain shield 11 through the inclined hole 12 and flow along the inner wall of the rain shield 11 to 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, thereby 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 providing a windshield 13 in the collection box 4, it is also possible to prevent airflow from passing through the rain shield 11 and affecting the natural irrigation effect of the leeward side thereof.

[0057] As a further embodiment of the present invention, a guide block 14 is fixed in the guide hole 10, a guide groove 15 is opened in the middle of the guide block 14, a rotating ball 16 is rotatably connected in the guide groove 15, and a water-permeable hole 17 is opened in the rotating ball 16 that passes through from top to bottom.

[0058] Specifically, since the guide plate 8 is in an inclined state, when rainwater falls along the diversion hole 10, part of the rainwater will flow along the surface of the guide plate 8 under the action of gravity due to the inclination angle and surface smoothness of the guide plate 8, rather than all of the rainwater dripping vertically through the diversion 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 the rainwater dripping position in the shielded area below the guide plate 8 being relatively concentrated, making it difficult to form a uniform dripping effect, which may make it impossible for plants in the area to receive rainwater irrigation uniformly. The present invention provides a diversion block 14 in the diversion hole 10 to guide the rainwater so that it can enter the water-permeable hole 17 in the rotating ball 16 and flow along the water-permeable hole 17. Falling, because the rotating ball 16 adopts an asymmetric mass distribution design, for example, a high-density metal counterweight is embedded in the bottom, and a lightweight engineering plastic is used on the top, this design allows the rotating ball 16 to always maintain a stable posture with the bottom facing downward when subjected to gravity. Even if the guide plate 8 flips over, the water permeable hole 17 in the rotating ball 16 can maintain a vertical state. Moreover, since the rotating ball 16 is spherical, the surfaces of the water permeable hole 17 on the rotating ball 16 are all higher than the bottom of the water permeable hole 17, forming a funnel-like closing structure, thereby ensuring that after rainwater enters the water permeable hole 17, it is not affected by the inclination angle of the guide plate 8 and always maintains a vertical falling state, thereby ensuring the uniformity of rainwater dripping in the shielded area below the guide plate 8.

[0059] As a further embodiment of the present invention, the adjusting component includes a rotating shaft 18, which is fixed on the side wall of the guide plate 8. A driving sleeve 19 is provided on the outer side of the rotating shaft 18. A mounting groove 20 is provided on the surface of the driving sleeve 19. A pushing pin 21 is inserted into the mounting groove 20. The pushing pin 21 is fixed on the rotating shaft 18. A spring 22 is fixed between the pushing pin 21 and the inner wall of the mounting groove 20. The driving sleeve 19 is rotatably connected to the side wall of the collecting box 4. A motor 23 is fixed on the outer wall of the collecting box 4. The output shaft of the motor 23 is fixedly connected to the driving sleeve 19.

[0060] Specifically, the driving sleeve 19 is driven to rotate by the driving assembly. When the driving sleeve 19 rotates forward, the pushing pin 21 is driven to move through the inner wall of the mounting groove 20, and the rotating shaft 18 is driven to rotate through the pushing pin 21, thereby driving the guide plate 8 to flip forward. When the driving sleeve 19 rotates reversely, the inner wall of the mounting groove 20 moves away from the pushing pin 21. Under the action of the gravity of the guide plate 8, the rotating shaft 18 and the pushing pin 21 can be automatically driven to move along with the mounting groove 20, thereby completing the reverse flipping of the guide plate 8.

[0061] Furthermore, in strong winds, when the guide plate 8 is located on the windward side, the wind will push the guide plate 8 to flip forward, thereby driving the push pin 21 to compress the spring 22 and flip it out of position. When the wind decreases, the push pin 21 is reset under the push of the spring 22, thereby driving the rotating shaft 18 and the guide plate 8 to reset. The guide plate 8 is provided with a certain range of flipping and making room, mainly to give the guide plate 8 a buffering ability to adapt to external forces in a windy environment. When strong winds act on the guide plate 8, the guide plate 8 can flip and move within the preset flipping and making room. This design can effectively alleviate the direct impact of the wind on the guide plate 8 and prevent the guide plate 8 from being structurally damaged or deformed due to excessive wind.

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

[0063] As a further implementation scheme of the present invention, an airbag ring 24 is fixed in the water-permeable hole 17, a guide tube 25 is inserted into the interior of the guide plate 8, and a plurality of branch tubes 26 are fixedly connected on the side wall of the guide tube 25. The branch tubes 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 to reduce the water guide channel of the airbag ring 24.

[0064] Specifically, due to the effect of wind, rainwater tends to fall in an inclined state. When rainwater falls on the windward side of the device, it will directly enter the shielding area of ​​the guide plate 8 along the inclined angle. At this time, the diversion holes 10 on the guide plate 8 are still continuously draining water downward, which can easily lead to excessive rainwater being poured on the windward side of the device, resulting in problems such as local water accumulation. To solve this problem, the present invention provides an airbag ring 24 in the diversion hole 10. Under normal conditions, the airbag ring 24 is installed inside the diversion hole 10, and the middle part of the airbag ring 24 has a diversion channel for rainwater to flow. Rainwater can flow downward from the diversion channel to achieve normal drainage function. When the guide plate 8 is on the windward side, the device's inflation and suction components will start working, inflating the diversion tube 25. 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 shrinking the diversion channel in the middle of the airbag ring 24, thereby effectively reducing the amount of rainwater poured on the windward side and avoiding excessive rainwater.

[0065] It should be noted that the branch pipe 26 is rotatably connected to the rotating ball 16 , and the branch pipe 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 charging and suction assembly includes a giveway groove 27, which is opened on the side wall of the guide plate 8. The inside of the giveway groove 27 is slidably connected to a moving rod 28, and a plurality of push plugs 29 are fixed on the moving rod 28. The push plugs 29 are inserted into the corresponding guide tubes 25. An elastic push rod 30 is provided on one side of the moving 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 moving rod 28. A cam 31 is provided on the other side of the moving rod 28, and the cam 31 is fixed on the drive sleeve 19.

[0067] Specifically, when the wind pushes the guide plate 8 to flip, the guide plate 8 drives the moving rod 28 to move, and 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 into the inside of the guide tube 25, thereby pushing the gas inside the guide tube 25 into the inside of the branch pipe 26, and then into the airbag ring 24 along the branch pipe 26, completing the inflation function of the airbag ring 24;

[0068] During the movement of the moving rod 28, the elastic push rod 30 will be 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, thereby completing the air suction 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, and the inner diameter of the through hole 34 is 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 the rainwater may still adhere to the inner ring surface of the airbag ring 24, which may easily cause the diversion channel to be blocked over time. To solve this problem, the present invention provides an elastic film 32 in the airbag ring 24 to separate the interior of the airbag ring 24 into a first chamber and a second chamber. At the initial stage of inflation, the gas first enters the first chamber. As the gas is continuously injected, the gas pressure in the first chamber gradually increases. When the air pressure inside the first chamber is greater than that in the second chamber, the elastic film 32 bends toward the second chamber under the action of the pressure difference. Since a plurality of protrusions 33 are pre-arranged on the surface of the elastic film 32, the corresponding positions on the outer surface of the airbag ring 24 become convex under the push of the protrusions 33, so that the surface of the entire airbag ring 24 changes from its 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 mutation. 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, prompting the impurities to detach from the surface.

[0071] It should be noted that in the initial stage of inflation, part of the gas will slowly enter the second chamber through the through holes 34 opened on the surface of the elastic film 32, causing the air pressure in the second chamber to gradually increase. However, since the aperture of the through holes 34 is designed to be small, the gas circulation speed is relatively slow. Therefore, the air pressure in the first chamber is always higher than that in the second chamber, thereby maintaining the tendency of the elastic film 32 to bulge toward the second chamber, ensuring that the concave and convex state of the surface of the airbag ring 24 is maintained.

[0072] When the suction process is started and reset is completed, the airbag ring 24 will return to a flat surface state. This flat surface can reduce the resistance of rainwater passing 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 formed on the inner wall of the mounting groove 20 . The groove 35 is provided at one end of the pushing pin 21 . A friction plate 36 is fixed in the groove 35 .

[0074] Specifically, the friction plate 36 is made of elastic material and has a rough surface. When the push pin 21 moves, the friction resistance increases after it contacts the friction plate 36, thereby limiting the moving speed of the push pin 21. The present invention provides a friction plate 36 at the end of the moving trajectory of the push pin 21. This design prevents the push pin 21 from contacting the friction plate 36 at the initial stage of movement. Only when the guide plate 8 flips a certain distance will the push pin 21 be hindered by the friction plate 36. In this way, during the inflation process, the initial stage is relatively slow due to the relatively fast flipping speed of the guide plate 8. Fast, it can be inflated at a faster speed, causing the elastic diaphragm to quickly produce a bulge 33, and the instantaneous pressure change causes a small vibration on the surface of the airbag ring 24, which preliminarily loosens 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 a stable pressure, so that the surface of the airbag ring 24 maintains a concave-convex structure, and then the continuous surface deformation and the turbulent effect generated by rainwater flowing through are used to further flush out impurities, achieving a more thorough cleaning effect.

[0075] As a further embodiment of the present invention, an overflow hole 37 is opened on the side wall of the guide hole 10, and the overflow hole 37 is connected to the interior of the guide groove 9.

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

[0077] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
