Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to rainwater garden recycling equipment with a flow self-adaptation function. Background Art

[0002] The rainwater garden reuse equipment is used to filter and collect rainwater, and then undergoes a series of filtration and purification to achieve the purpose of reuse. The reused rainwater can not only irrigate trees and wash roads, but also replenish groundwater resources, alleviating the problems of water shortage and ecological environment deterioration caused by urbanization.

[0003] However, the flow regulation modules of rainwater garden recycling systems currently available on the market are complex and require continuous power supply, resulting in high energy consumption and a high failure rate. Furthermore, the rainwater collection process generates a large number of bubbles, which, when burst, can cause cavitation in the recycling system's pipelines, thus shortening the overall service life of the recycling system. Therefore, a rainwater garden recycling system with flow adaptation is needed to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to provide a rainwater garden recycling device with flow self-adaptation 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 filter barrel, a connecting pipe and a water reservoir. The outlet of the filter barrel is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the inlet of the water reservoir. A regulating pipe is provided at the inlet of the filter barrel, and the outlet end of the regulating pipe is connected to the inlet of the filter barrel. A garbage screening module, a bubble elimination module and a flow regulating module are provided in the regulating pipe. The garbage screening module is provided at the inlet of the regulating pipe, and the garbage screening module and the regulating pipe are rotatably connected. The flow regulating module is provided at the outlet of the regulating pipe, and the flow regulating module and the regulating pipe are slidably connected. The bubble elimination module is provided in the regulating pipe, and the bubble elimination module is located between the garbage screening module and the flow regulating module. The bubble elimination module and the flow regulating module are fixedly connected, and the bubble elimination module and the regulating pipe are slidably connected.

[0006] When it rains, the rainwater will be mixed with garbage of a relatively large volume. The garbage mixed with the rainwater enters from the inlet of the regulating pipe. The garbage screening module screens out and collects the large-volume garbage from the regulating pipe. Subsequently, the rainwater passes through the bubble elimination module, which drives the bubble elimination module to converge the bubbles towards the central axis of the regulating pipe. Then, in cooperation with the flow regulation module, most of the bubbles are eliminated. When the rainwater flow rate increases, the force exerted by the rainwater on the bubble elimination module and the flow regulation module increases, and the flow regulation module gradually opens, increasing the cross-sectional area of the flow channel in the regulating pipe, thereby increasing the flow rate of the rainwater flowing into the filter barrel. After being filtered by the filter barrel, it is collected by the reservoir, improving the rainwater collection efficiency. At the same time, the force generated when the bubbles in the rainwater burst will also assist the regulation of the flow regulation module. When the rainwater flow rate decreases, the thrust of the rainwater on the bubble elimination module and the flow regulation module decreases, and the bubble elimination module and the flow regulation module slide towards the inlet of the regulating pipe, reducing the cross-sectional area of the flow channel in the regulating pipe, realizing the adaptive regulation of the flow rate.

[0007] Furthermore, diversion pipelines are arranged on both horizontal sides of the regulating pipe. The inlets of the two diversion pipelines are located between the garbage screening module and the bubble elimination module, and the outlets of the two diversion pipelines are located between the bubble elimination module and the flow regulation module.

[0008] When the rainwater flow rate suddenly surges, the high-speed flowing rainwater will cause a large impact force on the bubble elimination module and the flow regulation module, which will damage the bubble elimination module and the flow regulation module, reducing the service life of the reuse equipment. By setting the diversion pipelines, when the rainwater flow rate suddenly surges, the rainwater in the main flow channel of the regulating pipe is diverted, reducing the impact force on the bubble elimination module and the flow regulation module, and improving the service life of the reuse equipment.

[0009] Furthermore, a garbage bin, a filter plate, and a filter pipe are arranged on one horizontal side of the regulating pipe. The inlet of the garbage bin is communicated with the regulating pipe. The inlet of the garbage bin is located between the inlet of the regulating pipe and the garbage screening module. The outlet of the garbage bin is communicated with one end of the filter pipe. A filter plate is arranged inside one end of the filter pipe, and the filter plate is fixedly connected to the filter pipe. The outlet of the garbage bin is communicated with the inlet of the filter barrel.

[0010] The large-volume garbage mixed in the rainwater is blocked by the garbage screening module and is brought into the garbage bin by the water flow for collection. The rainwater in the garbage bin is filtered by the filter plate and enters the filter barrel through the filter pipe for filtration. By setting the filter pipe that communicates the garbage bin and the filter barrel, it effectively prevents the rainwater from being collected in the garbage bin and then flowing back, bringing the garbage in the garbage bin back into the regulating pipe and blocking the regulating pipe.

[0011] Further, the garbage screening module includes multiple rollers which are vertically arranged. The multiple rollers are rotationally connected to the adjusting pipe. The closer the multiple rollers are to the entrance of the garbage bin, the farther they are from the entrance of the adjusting pipe. The entrance of the garbage bin is located between the roller closest to the entrance of the garbage bin and the entrance of the adjusting pipe.

[0012] Driven by rainwater, large-volume garbage impacts on the rollers. With the continuous impact of rainwater, the large-volume garbage flows along the rollers towards the entrance of the garbage bin and finally enters the garbage bin. The rollers are rotationally connected to the adjusting pipe, facilitating the large-volume garbage to flow towards the garbage bin along the rollers when it impacts on the rollers.

[0013] Further, the bubble elimination module includes a bubble sliding seat, a bubble rotating ring and an impeller. The bubble sliding seat is located between the entrance of the shunt pipeline and the flow rate adjustment module. The bubble sliding seat is fixedly connected to the flow rate adjustment module. The bubble sliding seat is slidably connected to the adjusting pipe. The bubble rotating ring is rotationally connected to the bubble sliding seat. The outer edge of the impeller is fixedly connected to the bubble rotating ring. The central axis of the impeller coincides with the rotation axis of the bubble rotating ring.

[0014] When rainwater flows through the impeller, it drives the impeller and the bubble rotating ring to rotate. When the impeller rotates, affected by the centrifugal force, the bubbles in the rainwater will converge towards the central axis of the adjusting pipe, preventing the bubbles from bursting at the pipe wall of the adjusting pipe, causing cavitation erosion of the pipe wall of the adjusting pipe and greatly reducing the service life of the adjusting pipe.

[0015] Further, the impeller includes a central wheel shaft and blades. One end of the blade is fixedly connected to the central wheel shaft, and the other end of the blade is fixedly connected to the bubble rotating ring. One side of the blade extends beyond the entrance end of the central wheel shaft. The entrance aperture of the central wheel shaft is larger than the exit aperture. The central axis of the central wheel shaft coincides with the rotation axis of the bubble rotating ring.

[0016] One side of the blade extends beyond the entrance end of the central wheel shaft, generating a vortex before the entrance of the central wheel shaft, causing the bubbles to converge towards the central axis of the adjusting pipe in advance and thus enter the central wheel shaft. The entrance aperture of the central wheel shaft is larger than the exit aperture, and the water flow pressure is greater closer to the exit of the central wheel shaft. Tiny bubbles merge near the exit of the central wheel shaft, facilitating the subsequent collapse of the bubbles.

[0017] Further, a shear rod is arranged at the exit in the central wheel shaft. The shear rod penetrates the central wheel shaft along the radial direction of the central wheel shaft, and the shear rod is fixedly connected to the central wheel shaft.

[0018] The shear rod is responsible for initially collapsing the bubbles merged at the exit of the central wheel shaft, improving the collapse efficiency of the bubbles.

[0019] Furthermore, the flow rate adjustment module includes an anti-foaming rod, a sliding base, a return spring, a connecting rod, an adjusting piece, and an adjusting spring. The sliding base is slidably connected to the adjusting pipe, and the sliding base is fixedly connected to the bubble sliding seat. One end of the anti-foaming rod is inserted into the sliding base, and the anti-foaming rod is slidably connected to the sliding base. The return spring is arranged along the axial direction of the adjusting pipe. One end of the return spring is fixedly connected to the anti-foaming rod, and the other end of the return spring is fixedly connected to the sliding base. One end of the connecting rod is hinged to the end of the anti-foaming rod inserted into the sliding base, and the other end of the connecting rod is hinged to one end of the adjusting piece. The other end of the adjusting piece passes through the sliding base along the radial direction of the sliding base, and the adjusting piece is slidably connected to the sliding base. The adjusting spring is arranged along the axial direction of the adjusting pipe. One end of the adjusting spring is fixedly connected to the other end of the sliding base, and the other end of the adjusting spring is fixedly connected to the adjusting pipe.

[0020] When there is no rainwater flowing into the adjusting pipe, the sliding base blocks part of the outlet of the diversion pipeline. When the rainwater flow rate into the adjusting pipe increases, the rainwater flow velocity increases, and the impact force on the overall bubble elimination module and flow rate adjustment module increases. The adjusting spring compresses, and the sliding base slides towards the outlet of the adjusting pipe. The cross-sectional area of the outlet blocked by the sliding base in the diversion pipeline becomes smaller, and the flow rate in the diversion pipeline becomes larger, realizing the flow rate adjustment of the diversion pipeline. At the same time, under the impact force of the water flow and the impact force generated by the bubble collapse, the anti-foaming rod is pushed towards the outlet of the adjusting pipe, the return spring compresses, the anti-foaming rod drives the connecting rod, and the connecting rod then pushes the adjusting piece to slide radially outward along the sliding base, realizing the increase in the cross-sectional area of the flow channel in the adjusting pipe and increasing the rainwater flow rate in the adjusting pipe. When the rainwater flow rate into the adjusting pipe decreases, the return spring and the adjusting spring rebound, and the cross-sectional areas of the flow channels of the diversion pipeline and the adjusting pipe decrease.

[0021] Furthermore, an anti-foaming needle array is arranged on the end face of the anti-foaming rod facing the central wheel shaft, and the anti-foaming needle array points to the outlet of the central wheel shaft.

[0022] The bubbles flowing out from the outlet of the central wheel shaft impact on the anti-foaming needle array, and the anti-foaming needle array collapses the bubbles. The impact force generated by the bubble collapse simultaneously pushes the end face of the central wheel shaft, and then generates a certain thrust on the central wheel shaft. When the rainwater flow rate becomes larger, the bubble content in the rainwater becomes more, and the impact force generated by the bubble collapse becomes larger, thereby increasing the thrust on the central wheel shaft and realizing the rapid adjustment of the rainwater flow rate in the adjusting pipe.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention is provided with a garbage screening module. Driven by rainwater, large-volume garbage impacts on the drum. With the continuous impact of rainwater, the large-volume garbage flows along the drum towards the entrance of the garbage bin and finally enters the garbage bin for collection. 2. The present invention is provided with a bubble elimination module. When rainwater flows through the impeller, it drives the impeller and the bubble rotating ring to rotate. When the impeller rotates, under the influence of centrifugal force, the bubbles in the rainwater will converge towards the central axis of the regulating pipe, preventing the bubbles from bursting at the pipe wall of the regulating pipe, which may cause cavitation erosion of the pipe wall of the regulating pipe and greatly reduce the service life of the regulating pipe. One side of the blade extends beyond the inlet end of the central wheel shaft, generating a vortex before the inlet of the central wheel shaft, causing the bubbles to converge towards the central axis of the regulating pipe in advance, and then enter the central wheel shaft. The inlet aperture of the central wheel shaft is larger than the outlet aperture, and the water flow pressure is greater closer to the outlet of the central wheel shaft. Tiny bubbles merge near the outlet of the central wheel shaft, facilitating the subsequent collapse of the bubbles. 3. The present invention is provided with a flow rate adjustment module. When the flow rate of rainwater flowing into the regulating pipe increases, the flow velocity of the rainwater increases, and the impact force on the overall bubble elimination module and flow rate adjustment module increases. The adjusting spring is compressed, and the sliding base slides towards the outlet of the regulating pipe. The outlet cross-sectional area blocked by the sliding base in the shunt pipeline becomes smaller, and the flow rate in the shunt pipeline becomes larger, realizing the flow rate adjustment of the shunt pipeline. At the same time, under the impact force of the water flow and the impact force generated by the collapse of the bubbles, the defoaming rod is pushed towards the outlet of the regulating pipe, the reset spring is compressed, the defoaming rod drives the connecting rod, and the connecting rod then pushes the adjusting piece to slide radially outward along the sliding base, realizing an increase in the cross-sectional area of the flow channel inside the regulating pipe and increasing the rainwater flow rate inside the regulating pipe. When the flow rate of rainwater flowing into the regulating pipe decreases, the reset spring and the adjusting spring rebound, and the cross-sectional areas of the flow channels of the shunt pipeline and the regulating pipe decrease.

Detailed implementation manner

[0026] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment: As Figure 1 - Figure 8 shown, the present invention provides a technical solution for a rain garden reuse device with a flow self-adaptive function: As Figures 1 - 3 shown, the reuse device includes a filtration barrel 1, a connecting pipe 2 and a reservoir 3. The outlet of the filtration barrel 1 is communicated with one end of the connecting pipe 2, and the other end of the connecting pipe 2 is communicated with the inlet of the reservoir 3. A regulating pipe 4 is arranged at the inlet of the filtration barrel 1. The outlet end of the regulating pipe 4 is communicated with the inlet of the filtration barrel 1. A garbage screening module 5, a bubble elimination module 6 and a flow regulation module 7 are arranged in the regulating pipe 4. The garbage screening module 5 is arranged at the inlet in the regulating pipe 4. The garbage screening module 5 is rotationally connected with the regulating pipe 4. The flow regulation module 7 is arranged at the outlet in the regulating pipe 4. The flow regulation module 7 is slidably connected with the regulating pipe 4. The bubble elimination module 6 is arranged in the regulating pipe 4. The bubble elimination module 6 is located between the garbage screening module 5 and the flow regulation module 7. The bubble elimination module 6 is fixedly connected with the flow regulation module 7. The bubble elimination module 6 is slidably connected with the regulating pipe 4.

[0028] When it rains, the rainwater will be mixed with garbage of a relatively large volume. The garbage mixed with the rainwater enters from the inlet of the regulating pipe 4. The garbage screening module 5 screens out and collects the large-volume garbage from the regulating pipe 4. Subsequently, the rainwater passes through the bubble elimination module 6, which drives the bubble elimination module 6 to converge the bubbles towards the central axis of the regulating pipe 4. Then, in cooperation with the flow rate regulating module 7, most of the bubbles are eliminated. When the rainwater flow rate increases, the force of the rainwater pushing the bubble elimination module 6 and the flow rate regulating module 7 increases. The flow rate regulating module 7 gradually opens, increasing the cross-sectional area of the flow channel in the regulating pipe 4, thereby increasing the flow rate of the rainwater flowing into the filter barrel 1. After being filtered by the filter barrel 1, it is collected by the reservoir 3, improving the rainwater collection efficiency. At the same time, the force generated when the bubbles in the rainwater burst will also assist in the regulation of the flow rate regulating module 7. When the rainwater flow rate decreases, the thrust of the rainwater on the bubble elimination module 6 and the flow rate regulating module 7 decreases. The bubble elimination module 6 and the flow rate regulating module 7 slide towards the inlet of the regulating pipe 4, reducing the cross-sectional area of the flow channel in the regulating pipe 4, realizing the adaptive regulation of the flow rate.

[0029] As Figure 2 and Figure 3 shown, diversion pipelines 41 are arranged on both horizontal sides of the regulating pipe 4. The inlets of the two diversion pipelines 41 are located between the garbage screening module 5 and the bubble elimination module 6, and the outlets of the two diversion pipelines 41 are located between the bubble elimination module 6 and the flow rate regulating module 7.

[0030] When the rainwater flow rate suddenly surges, the high-speed flowing rainwater will cause a large impact force on the bubble elimination module 6 and the flow rate regulating module 7, which will damage the bubble elimination module 6 and the flow rate regulating module 7, reducing the service life of the reuse equipment. By setting the diversion pipelines 41, when the rainwater flow rate suddenly surges, the rainwater in the main flow channel of the regulating pipe 4 is diverted, reducing the impact force on the bubble elimination module 6 and the flow rate regulating module 7, and improving the service life of the reuse equipment.

[0031] As Figure 2 shown, a garbage bin 42, a filter plate 43 and a filter pipe 44 are arranged on one horizontal side of the regulating pipe 4. The inlet of the garbage bin 42 is communicated with the regulating pipe 4. The inlet of the garbage bin 42 is located between the inlet of the regulating pipe 4 and the garbage screening module 5. The outlet of the garbage bin 42 is communicated with one end of the filter pipe 44. A filter plate 43 is arranged inside one end of the filter pipe 44. The filter plate 43 is fixedly connected to the filter pipe 44. The outlet of the garbage bin 42 is communicated with the inlet of the filter barrel 1.

[0032] Large-volume garbage mixed in rainwater is blocked by the garbage screening module 5 and is carried by the water flow into the garbage bin 42 for collection. The rainwater in the garbage bin 42 is filtered by the filter plate 43 and enters the filter barrel 1 through the filter pipe 44 for filtration. The filter pipe 44 connecting the garbage bin 42 and the filter barrel 1 is provided, effectively preventing the rainwater from being collected in the garbage bin 42 and then causing a backflow phenomenon, bringing the garbage in the garbage bin 42 back into the regulating pipe 4 and blocking the regulating pipe 4.

[0033] As Figure 2 and Figure 3 shown, the garbage screening module 5 includes multiple rollers 51. The multiple rollers 51 are vertically arranged. The multiple rollers 51 are rotationally connected to the regulating pipe 4. The closer the multiple rollers 51 are to the entrance of the garbage bin 42, the farther they are from the entrance of the regulating pipe 4. The entrance of the garbage bin 42 is located between the roller 51 closest to the entrance of the garbage bin 42 and the entrance of the regulating pipe 4.

[0034] Driven by the rainwater, the large-volume garbage impacts on the roller 51. With the continuous impact of the rainwater, the large-volume garbage flows along the roller 51 towards the entrance of the garbage bin 42 and finally enters the garbage bin 42. The roller 51 is rotationally connected to the regulating pipe 4, facilitating the large-volume garbage to flow along the roller 51 towards the garbage bin 42 when it impacts on the roller 51.

[0035] As Figure 4 , Figure 6 and Figure 7 shown, the bubble elimination module 6 includes a bubble sliding seat 61, a bubble rotating ring 62 and an impeller 63. The bubble sliding seat 61 is located between the entrance of the shunt pipeline 41 and the flow regulation module 7. The bubble sliding seat 61 is fixedly connected to the flow regulation module 7. The bubble sliding seat 61 is slidably connected to the regulating pipe 4. The bubble rotating ring 62 is rotationally connected to the bubble sliding seat 61. The outer edge of the impeller 63 is fixedly connected to the bubble rotating ring 62. The central axis of the impeller 63 coincides with the rotation axis of the bubble rotating ring 62.

[0036] When the rainwater flows through the impeller 63, it drives the impeller 63 and the bubble rotating ring 62 to rotate. When the impeller 63 rotates, affected by the centrifugal force, the bubbles in the rainwater will converge towards the central axis of the regulating pipe 4, preventing the bubbles from bursting at the wall of the regulating pipe 4 and causing cavitation erosion of the wall of the regulating pipe 4, greatly reducing the service life of the regulating pipe 4.

[0037] As Figure 4 , Figure 6 and Figure 7As shown in the figure, the impeller 63 includes a central wheel shaft 64 and blades 65. One end of each blade 65 is fixedly connected to the central wheel shaft 64, and the other end of each blade 65 is fixedly connected to the bubble swivel ring 62. One side of each blade 65 extends beyond the inlet end of the central wheel shaft 64. The inlet aperture of the central wheel shaft 64 is larger than the outlet aperture. The central axis of the central wheel shaft 64 coincides with the rotation axis of the bubble swivel ring 62.

[0038] One side of each blade 65 extends beyond the inlet end of the central wheel shaft 64, generating a vortex before the inlet of the central wheel shaft 64, causing the bubbles to converge towards the central axis of the regulating pipe 4 in advance, and thus entering the central wheel shaft 64. Since the inlet aperture of the central wheel shaft 64 is larger than the outlet aperture, the water flow pressure is greater closer to the outlet of the central wheel shaft 64, and the tiny bubbles merge near the outlet of the central wheel shaft 64, facilitating the subsequent collapse of the bubbles.

[0039] As Figure 4 shown in the figure, a shear rod 66 is provided at the outlet inside the central wheel shaft 64. The shear rod 66 passes through the central wheel shaft 64 along the radial direction of the central wheel shaft 64, and the shear rod 66 is fixedly connected to the central wheel shaft 64.

[0040] The shear rod 66 is responsible for initially collapsing the bubbles merged at the outlet of the central wheel shaft 64, improving the collapse efficiency of the bubbles.

[0041] As Figures 3 - 6 and Figure 7 shown in the figure, the flow rate regulating module 7 includes an anti-foaming rod 71, a sliding base 72, a return spring 73, a connecting rod 74, a regulating piece 75, and a regulating spring 76. The sliding base 72 is slidably connected to the regulating pipe 4. The sliding base 72 is fixedly connected to the bubble sliding seat 61. One end of the anti-foaming rod 71 is inserted into the sliding base 72, and the anti-foaming rod 71 is slidably connected to the sliding base 72. The return spring 73 is arranged along the axial direction of the regulating pipe 4. One end of the return spring 73 is fixedly connected to the anti-foaming rod 71, and the other end of the return spring 73 is fixedly connected to the sliding base 72. One end of the connecting rod 74 is hinged to the end of the anti-foaming rod 71 inserted into the sliding base 72, and the other end of the connecting rod 74 is hinged to one end of the regulating piece 75. The other end of the regulating piece 75 passes through the sliding base 72 along the radial direction of the sliding base 72, and the regulating piece 75 is slidably connected to the sliding base 72. The regulating spring 76 is arranged along the axial direction of the regulating pipe 4. One end of the regulating spring 76 is fixedly connected to the other end of the sliding base 72, and the other end of the regulating spring 76 is fixedly connected to the regulating pipe 4.

[0042] When there is no rainwater flowing into the regulating pipe 4, the sliding base 72 blocks part of the outlet of the diversion pipeline 41. When the rainwater flow rate into the regulating pipe 4 increases, the rainwater velocity increases, and the impact force on the bubble elimination module 6 and the flow rate regulating module 7 as a whole increases. The regulating spring 76 compresses, and the sliding base 72 slides towards the outlet of the regulating pipe 4. The cross-sectional area of the outlet of the diversion pipeline 41 blocked by the sliding base 72 becomes smaller, and the flow rate in the diversion pipeline 41 becomes larger, realizing the flow rate regulation of the diversion pipeline 41. At the same time, under the impact force of the water flow and the impact force generated by the bubble collapse, the defoaming rod 71 is pushed towards the outlet of the regulating pipe 4, the reset spring 73 compresses, the defoaming rod 71 drives the connecting rod 74, and the connecting rod 74 further pushes the regulating piece 75 to slide radially outward along the sliding base 72, realizing an increase in the cross-sectional area of the flow channel in the regulating pipe 4 and increasing the rainwater flow rate in the regulating pipe 4. When the rainwater flow rate into the regulating pipe 4 decreases, the reset spring 73 and the regulating spring 76 rebound, and the cross-sectional areas of the flow channels of the diversion pipeline 41 and the regulating pipe 4 decrease.

[0043] As Figure 4 , Figure 5 and Figure 7 shown, on the end face of the defoaming rod 71 facing the central wheel shaft 64, a defoaming needle array 77 is provided, and the defoaming needle array 77 points to the outlet of the central wheel shaft 64.

[0044] The bubbles flowing out from the outlet of the central wheel shaft 64 impact on the defoaming needle array 77, and the defoaming needle array 77 collapses the bubbles. The impact force generated by the bubble collapse simultaneously pushes the end face of the central wheel shaft 64, and then generates a certain thrust on the central wheel shaft 64. When the rainwater flow rate becomes larger, the bubble content in the rainwater becomes more, and the impact force generated when the bubbles collapse becomes larger, thereby increasing the thrust on the central wheel shaft 64 and realizing the rapid regulation of the rainwater flow rate in the regulating pipe 4.

[0045] The working principle of the present invention: When it rains, larger volume of garbage will be mixed in the rainwater. The garbage mixed with the rainwater enters from the inlet of the regulating pipe 4. The garbage screening module 5 screens out and collects the large-volume garbage from the regulating pipe 4. Subsequently, the rainwater passes through the bubble elimination module 6, which drives the bubble elimination module 6 to converge the bubbles towards the central axis of the regulating pipe 4. Then, in cooperation with the flow rate regulating module 7, most of the bubbles are eliminated. When the rainwater flow rate becomes larger, the force of the rainwater pushing the bubble elimination module 6 and the flow rate regulating module 7 increases, and the flow rate regulating module 7 gradually opens, increasing the cross-sectional area of the flow channel in the regulating pipe 4, thereby increasing the rainwater flow rate into the filter barrel 1. After being filtered by the filter barrel 1, it is collected by the reservoir 3, improving the rainwater collection efficiency. At the same time, the force generated when the bubbles in the rainwater burst will also assist in the regulation of the flow rate regulating module 7. When the rainwater flow rate becomes smaller, the thrust of the rainwater on the bubble elimination module 6 and the flow rate regulating module 7 decreases, and the bubble elimination module 6 and the flow rate regulating module 7 slide towards the inlet of the regulating pipe 4, and the cross-sectional area of the flow channel in the regulating pipe 4 decreases, realizing the adaptive regulation of the flow rate.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
