[0002] At present, in the field of new energy, photovoltaic power generation has been widely used as an important form of clean energy. However, in the construction and operation of photovoltaic power stations, how to reasonably utilize natural resources and optimize the ecological environment needs to be focused on. Especially under the layout of large-scale photovoltaic power generation facilities, the management of rainwater resources has not been effectively utilized for a long time, resulting in prominent waste of water resources and imbalance of the local ecological environment.

[0003] In the existing technology, although some photovoltaic power generation facilities have a certain ability to collect rainwater, they generally have problems such as low collection efficiency, single storage method, and low subsequent utilization rate. On the one hand, precipitation is uncertain under different climatic conditions, and it is difficult for existing solutions to effectively capture and guide it, which limits the collection process of rainwater resources and makes it impossible to give full play to their value. On the other hand, although some photovoltaic power generation sites are equipped with simple storage equipment, due to the lack of scientific transportation and distribution mechanisms, it is difficult to achieve efficient recycling of rainwater resources. In addition, in arid or semi-arid areas, the ecological environment of the site is relatively fragile, and the existing technology has not yet formed a set of systematic solutions that take into account resource utilization and ecological balance, and it is difficult to meet the sustainability requirements of long-term operation.

[0029] Although some photovoltaic power generation facilities in the related art have the ability to collect rainwater, there are still problems such as low collection efficiency, single storage method, and low subsequent utilization rate. Affected by climatic conditions, the precipitation is uncertain, and the existing solutions are difficult to effectively capture and guide rainwater, resulting in limited collection process and insufficient utilization of water resources. In addition, although some photovoltaic power stations are equipped with simple storage equipment, due to the imperfect conveying and distribution mechanisms, it is difficult to achieve efficient recycling of rainwater resources.

[0030] To solve all or part of the above technical problems in the related art, referring to Figures 1 - 10 As shown, the present disclosure provides a rainwater collection, storage and utilization device for a photovoltaic power station, including a green plant shed 1. A photovoltaic panel 11 and a water guiding component 2 are installed on the top of the green plant shed 1, and the water guiding component 2 is located on one side of the lowest point in the vertical direction of the photovoltaic panel 11. A first water conveying component 6 is arranged below the water guiding component 2, and the first water conveying component 6 is slidably connected to the side of the green plant shed 1. A rainwater irrigation component 3 for irrigating the plants inside the green plant shed 1 is installed inside the green plant shed 1. A water storage bucket 4 is arranged on one side of the green plant shed 1, and a second water conveying component 7 is installed between the water storage bucket 4 and the green plant shed 1. The second water conveying component 7 is used to establish a connection among the rainwater irrigation component 3, the water storage bucket 4 and the first water conveying component 6. A water pump 8 is also installed on the water storage bucket 4. One end of the water pump 8 is communicated with the water storage bucket 4, and the other end of the water pump 8 is communicated with the rainwater irrigation component 3.

[0031] Among them, the green plant shed 1, as the main structure of the device, bears the photovoltaic panel 11, the water guiding component 2, the first water conveying component 6, the rainwater irrigation component 3, the water storage bucket 4 and the second water conveying component 7, ensures the stable installation of each component, and provides support for the growth of green plants. The green plant shed 1 is made of a metal alloy with strong weather resistance or a high-strength composite material to enhance its wind resistance and corrosion resistance, and at the same time has good load-bearing performance to adapt to the long-term outdoor use environment of the photovoltaic power station. The outer surface can be treated with an anti-rust coating or anodic oxidation to improve durability and reduce maintenance requirements. In addition, the frame structure design of the green plant shed 1 reserves adaptable interfaces, enabling it to adjust the layout according to different site conditions to ensure that the device can operate efficiently in a variety of application environments.

[0032] The photovoltaic panel 11 is fixedly installed on the top of the green plant trellis 1, which is used for photovoltaic power generation and also serves as the primary rainwater receiving surface to improve the collection efficiency of precipitation. The tilt angle of the photovoltaic panel 11 is optimized according to the local light conditions and precipitation characteristics, so that it can not only receive solar energy to the maximum extent, but also promote the flow of rainwater to the lowest point. The surface layer of the panel is coated with a low surface energy coating, such as fluoride, to reduce water droplet residue, increase the rainwater collection speed, and at the same time reduce dust adhesion and improve the power generation efficiency. The support part of the panel can be made of aluminum alloy or stainless steel to ensure light weight and durability, and have good wind load resistance to ensure long-term stable operation.

[0033] The water guiding component 2 is installed on one side of the lowest point in the vertical direction of the photovoltaic panel 11, and its function is to direct the rainwater to ensure that the water flow enters the water conveyance system along the set path. The water guiding component 2 is composed of a water guiding groove and a water guiding pipe. The water guiding groove can be made of high-density polyethylene or stainless steel to ensure corrosion resistance and weather resistance, and at the same time have a smooth inner wall structure to reduce water flow resistance and improve the conveying efficiency. The water guiding pipe is connected to the water guiding groove and is made of PVC, PPR or corrosion-resistant metal pipe to enhance the structural strength and anti-corrosion performance and ensure the stability of long-term outdoor use.

[0034] The first water conveyance component 6 is located below the water guiding component 2 and is slidably connected to the side of the green plant trellis 1, so that it can be adjusted adaptively according to the precipitation and water conveyance requirements to improve the flexibility of water flow conveyance. The first water conveyance component 6 is composed of a water inlet platform, a water conveyance pipe and a filtering device. The water inlet platform can be made of stainless steel to improve the impact resistance and ensure the smooth introduction of water flow into the water conveyance system. The water conveyance pipe can be made of PE, PPR or galvanized steel pipe to balance flexibility and durability, so that it can adapt to different site conditions and withstand the water flow scouring during long-term use. The filtering device is located in the water conveyance path, and the filter element is made of high-density polypropylene or stainless steel mesh, which can effectively remove impurities such as sediment and leaves in the rainwater, improve the water quality and make it suitable for subsequent irrigation or storage.

[0035] The rainwater irrigation component 3 is installed inside the green plant trellis 1 to ensure that the water resources are directly used for plant growth and improve the rainwater utilization rate. The rainwater irrigation component 3 is composed of a water storage pipe, a spray pipe and a spray head. The spray pipe can be made of PVC or aluminum alloy to ensure light weight and durability and ensure uniform water flow distribution. The spray head can adopt an adjustable flow design, and the material is selected from ABS plastic or brass to adapt to the water requirements of different plants, improve the irrigation uniformity and reduce water resource waste.

[0036] The water storage bucket 4 is located on one side of the green plant trellis 1 and is used to store excess rainwater for use during dry periods or when the water demand increases. The material of the water storage bucket 4 can be selected as high-density polyethylene or fiberglass reinforced plastic, which has corrosion resistance, ultraviolet resistance and anti-aging properties and is suitable for long-term outdoor use. A liquid level monitoring device is provided inside to detect the water level height in real time and trigger a water pump or a drain valve when the set threshold is reached, preventing overflow or water shortage from affecting the operation of the irrigation system. The bucket cover of the water storage bucket adopts a detachable design, which is convenient for cleaning and maintenance, and at the same time prevents impurities such as dust and insects from entering the stored water source and affecting the water quality.

[0037] The second water delivery component 7 connects the rainwater irrigation component 3, the water storage bucket 4 and the first water delivery component 6, enabling each part to form a connected system to ensure the reasonable distribution of rainwater among different paths. The second water delivery component 7 consists of multiple water pipes and valves. The valves can be made of brass or stainless steel and have wear resistance and pressure resistance characteristics to ensure the reliability of flow regulation. The water delivery component adopts an adjustable flow splitting mechanism, allowing rainwater to be preferentially supplied for irrigation and only guided to the water storage bucket when there is sufficient storage space, improving the water resource regulation ability.

[0038] The water pump 8 is installed on the water storage bucket 4 to provide the power for water delivery, ensuring that rainwater can still be stably supplied to the rainwater irrigation component 3 during low water levels or long-distance transportation. The start mode of the water pump 8 can be automatically controlled by the liquid level monitoring device to ensure timely start when water is needed and automatic stop when the water volume is sufficient, so as to optimize energy consumption management.

[0039] In the actual application process, the rainwater collection, storage and utilization device relies on the inclined structure of the photovoltaic panel 11 to guide rainwater to the lowest point during rainfall and collect it efficiently through the water guide assembly 2, which converges and flows to the first water conveyance assembly 6. The rainwater enters the water guide pipe through the water guide groove, falls into the water inlet platform under the action of gravity, and is distributed along the water conveyance path. Part of the rainwater is directly conveyed to the rainwater irrigation assembly 3 through the first water conveyance assembly 6. Through the uniform distribution of the water storage pipe and the spray pipe, it is atomized and sprayed by the spray head to achieve precise irrigation of the green plants. At the same time, according to the different water requirements of the plants, the flow rate of the adjustable spray head is used to optimize the water supply and avoid over-irrigation or water resource waste. When the rainfall is large, the first water conveyance assembly 6 continuously conveys the rainwater under the action of gravity, and the second water conveyance assembly 7 establishes a communication path between the rainwater irrigation assembly 3 and the water storage bucket 4 according to the water flow state, so that the excess rainwater enters the water storage bucket 4 for storage for subsequent use. A liquid level monitoring device is provided inside the water storage bucket 4 to monitor the water level change in real time. When the storage amount is close to the upper limit, the water pump 8 can be automatically started according to the liquid level signal to convey the stored water to the rainwater irrigation assembly 3, ensuring that the water resource can still be recycled during drought or insufficient rainfall to maintain a stable water supply for the green plants. In the case of continuous drought or insufficient rainfall, the water pump 8 actively pumps the rainwater in the water storage bucket 4 and conveys it to the rainwater irrigation assembly 3 through the second water conveyance assembly 7 to maintain the normal growth of the green plants. At the same time, the water resource distribution can be optimized by adjusting the valve to improve the water utilization rate and avoid unnecessary losses.

[0040] Next, the rainwater collection, storage and utilization device for a photovoltaic power station of the present disclosure will be further described in other embodiments.

[0041] In some embodiments, a plurality of mutually engaged green plant pots 12 are installed at the bottom of the inner wall of the green plant shed 1. By providing the green plant pots 12, it is convenient to place or transfer green plants to other places in the power plant. Among them, the engaging structure design of the green plant pots 12 adopts a nested or slot-type connection, enabling them to be firmly fixed without using additional fasteners, reducing the installation difficulty, and enhancing the flexibility and adaptability of the overall structure. The bottom of the green plant pot 12 can be designed with a drainage hole structure to prevent waterlogging from causing root rot of the plants. At the same time, a detachable filter screen or absorbent cotton is equipped to adjust the water penetration rate to ensure a balanced soil humidity and improve the plant survival rate. To improve the convenience of transportation, the bottom of the green plant pot 12 can be equipped with hidden rollers or sliding brackets, enabling it to move smoothly on the hard ground inside the photovoltaic power station and reducing the labor consumption during the handling process.

[0042] In some embodiments, the water guiding assembly 2 includes a water guiding pipe 21 and a water guiding groove 22. A side groove for receiving the rainwater of the photovoltaic panel 11 is formed in the water guiding groove 22. The top end of the water guiding pipe 21 is communicated with the water guiding groove 22, and the bottom end of the water guiding pipe 21 is located directly above the first water conveying assembly 6. Among them, the water guiding groove 22 cooperates with the water guiding plate 11 to be able to receive rainwater and collect the rainwater. The water guiding groove 22 itself can also protect the green plant shed 1 from rain, and after the rainwater is collected, it is led out through the water guiding pipe 21 to the first water conveying assembly 6, which is convenient for subsequent operations. An anti-blocking filter screen or a small grille can be arranged inside the water guiding groove 22 to prevent fallen leaves, dust or impurities from entering the water guiding pipe 21, avoid clogging of the water flow channel, and improve the long-term operation stability of the system. The bottom of the water guiding pipe 21 can be designed into a funnel shape or an arc-shaped closing structure to ensure that the water flow can flow centrally when falling into the first water conveying assembly 6, and reduce the impact loss caused by the dispersion of the water flow. In other embodiments of the present disclosure, the water guiding pipe 21 can be equipped with a connecting piece with an adjustable angle, so that it can be adjusted according to different installation angles or water flow requirements to adapt to different inclination angles of the photovoltaic panel 11 and changes in precipitation. In addition, the water guiding pipe 21 can adopt a telescopic pipe design, so that it can adjust the length according to the actual water flow requirements to ensure efficient transportation under different rainfall conditions.

[0043] In some embodiments, the rainwater irrigation assembly 3 includes two water storage pipes 31. A plurality of spray pipes 32 are communicated between the two water storage pipes 31, and a plurality of spray heads 33 are installed at the bottom of each spray pipe 32. The arranged water storage pipes 31 are matched with the spray pipes 32 to achieve covering watering over the entire green plants. The spray heads 33 are further used to irrigate the water more evenly. Among them, the spray heads 33 can adopt various spraying modes, including micro-spraying, atomized spraying and directional drip irrigation, etc., to adapt to the growth requirements of different types of green plants. In other embodiments of the present disclosure, a flow control valve can be arranged at the connection between the water storage pipe 31 and the spray pipe 32 to adjust the water flow according to the irrigation requirements of different regions, ensure the balanced water supply of each spray head 33, and avoid excessive local water pressure affecting the spraying effect. In order to further improve the intelligent level of the system, a humidity sensor and a flow regulating device can also be installed on the water storage pipe 31, so that the spray system can automatically adjust the water flow according to the environmental humidity, achieve precise irrigation, and optimize the utilization of water resources.

[0044] In some embodiments, the first water conveying assembly 6 includes a water inlet platform 61. The water inlet platform 61 is located directly below the water guiding pipe 21. A first water conveying pipe 62 is communicated with the bottom of the water inlet platform 61. Two filter pipes 63 are communicated with the first water conveying pipe 62. The output ends of the two filter pipes 63 are both abutted against the surface of the second water conveying assembly 7. The bottom end of the first water conveying pipe 62 is slidably connected with a positioning rod 67. The bottom of the positioning rod 67 is fixed to the second water conveying assembly 7. A spring 66 is also installed inside the positioning rod 67; among them, a filter element 65 is inserted into the filter pipe 63.

[0045] Specifically, the first water delivery component 6 collects the rainwater flowing out of the water conduit 21 through the water inlet platform 61 and ensures that the water flows smoothly into the first water delivery pipe 62. The bottom of the water inlet platform 61 is funnel-shaped, which optimizes the water flow guidance, reduces splashing and water accumulation, and improves the delivery efficiency. The first water delivery pipe 62 is hermetically connected to the water inlet platform 61 and is made of corrosion-resistant material with a smooth inner surface to reduce water resistance and sedimentation and improve the water flow stability. The first water delivery pipe 62 communicates with two filter pipes 63, and filter elements 65 are inserted into the filter pipes 63 to remove suspended impurities and improve the water quality. The filter elements 65 are designed to be replaceable, and their materials can be polypropylene or stainless steel mesh materials to ensure the filtering effect and long-term use stability. The output end of the filter pipe 63 is hermetically abutted against the second water delivery component 7 to prevent leakage, and the reliability of the connection is improved through a flexible joint or a sealing ring. The bottom end of the first water delivery pipe 62 is slidably connected to a positioning rod 67, and the bottom of the positioning rod 67 is fixed to the second water delivery component 7 to ensure that the pipeline can dynamically adjust its position under the action of water flow, reduce impact, and improve the system stability. A spring 66 is installed inside the positioning rod 67, and the spring 66 provides a buffering effect, enabling the first water delivery pipe 62 to be appropriately adjusted under the impact of water flow and automatically restore its position when the water flow weakens, optimizing the water delivery path, and improving the durability and adaptability.

[0046] In some embodiments, two sliding rings 64 are installed on the first water delivery pipe 62, and both sliding rings 64 are slidably connected to the side of the green plant trellis 1. Among them, the sliding rings 64 are used to support and guide the first water delivery pipe 62, enabling it to make adaptive adjustments when affected by water flow impact or environmental changes, and improving the stability and flexibility of the water delivery system. The two sliding rings 64 are respectively installed at different positions on the first water delivery pipe 62 to disperse the load brought by the water flow impact and prevent the pipeline from shaking or misaligning during water delivery. The sliding rings 64 are slidably connected to the side of the green plant trellis 1, and their sliding structures can be rail type, groove-embedded type, or ball sliding structure to ensure that the first water delivery pipe 62 can move adaptively under the change of water pressure and remain stable in the state of no water flow or low water flow, avoiding unnecessary shaking or falling off. The sliding rings 64 can be installed in a snap-on or bolt-fixed manner, enabling them to be quickly disassembled or adjusted when necessary, which is convenient for maintenance and replacement.

[0047] In some embodiments, the second water delivery component 7 includes a partition plate 71. One side of the partition plate 71 communicates with a second water delivery pipe 73 and a third water delivery pipe 75. The third water delivery pipe 75 is communicated with the water storage bucket 4, and the second water delivery pipe 73 is communicated with the rainwater irrigation component 3. A water valve 74 is installed on the second water delivery pipe 73. Among them, In some embodiments, two sealing rings 72 for temporarily sealing the pipeline, which are fitted with the filter pipe 63, are installed on one side of the partition plate 71 away from the third water delivery pipe 75. The first water delivery assembly 6 and the second water delivery assembly 7 cooperate to be linked according to the weight and impact force generated by the actual rainfall amount, and finally achieve different effects according to different rainfall amounts, so as to select irrigation or storage. Among them, the partition plate 71 plays a role of water flow distribution and path isolation in the second water delivery assembly 7, ensuring the reasonable diversion of rainwater between different delivery paths and improving the utilization efficiency of water resources. One side of the partition plate 71 is communicated with the second water delivery pipe 73 and the third water delivery pipe 75, enabling rainwater to flow to the rainwater irrigation assembly 3 or the water storage bucket 4 under different demand scenarios, realizing the flexible switching between irrigation and storage. In other embodiments of the present disclosure, the water valve 74 can be an electromagnetic valve, and the water valve 74 can be linked with a humidity sensor and an automatic control system to accurately adjust the rainwater flow direction and optimize the water resource utilization efficiency. When rainfall occurs, the water guiding assembly 2 introduces the rainwater collected by the photovoltaic panel 11 into the first water delivery assembly 6. After the water flow is treated by the filter pipe 63, it enters the second water delivery assembly 7. At this time, the electromagnetic valve judges the current irrigation demand according to the logic set by the system. When the humidity sensor detects that the soil moisture content in the green plant area is low, the system controls the electromagnetic valve to open the second water delivery pipe 73, so that the rainwater is directly delivered to the rainwater irrigation assembly 3. If the soil humidity reaches the set threshold, the electromagnetic valve automatically closes the second water delivery pipe 73 and simultaneously opens the third water delivery pipe 75, enabling the rainwater to enter the water storage bucket 4 for storage for subsequent use during drought. When the water level in the water storage bucket 4 reaches the upper limit, the system can send a signal to control the electromagnetic valve to close the third water delivery pipe 75 to prevent waste of water resources.

[0048] In some embodiments, a linkage frame 5 is provided on the water storage bucket 4. The linkage frame 5 includes a first support 51 and a floating plate 52. The floating plate 52 is located inside the water storage bucket 4, and the top end of the floating plate 52 penetrates and extends out of the water storage bucket 4. A first support 51 is connected to the extended end of the floating plate 52, and a second support 53 is installed at the bottom of the first support 51. The second support 53 is located directly below the adjacent filter pipe 63. Among them, the linkage frame 5 is used to detect the water level change in the water storage bucket 4 and control the water inlet state of the filter pipe 63 through mechanical linkage to optimize the storage and delivery of rainwater. The floating plate 52 is located inside the water storage bucket 4, and its main function is to move up or down with the water level to drive the entire linkage frame 5 to make corresponding adjustments. The first support 51 is connected to the extended end of the floating plate 52, and its main function is to transfer the displacement of the floating plate 52 to the second support 53 and control the water inlet path of the filter pipe 63. The second support 53 is installed at the bottom of the first support 51 and is located directly below the adjacent filter pipe 63, and its main function is to control the water inlet channel of the filter pipe 63.

[0049] Furthermore, when the water level in the water storage bucket 4 has not reached the upper limit, the second support 53 is in a sunken state and does not exert an additional effect on the filter pipe 63, allowing rainwater to flow into the water storage bucket 4 normally for storage. When the water level in the water storage bucket 4 rises to the upper limit, the floating plate 52 rises accordingly, driving the first support 51 to move upward. The first support 51 further pushes up the second support 53, causing it to press against the water inlet of the filter pipe 63 upward, thereby physically closing the path for rainwater to enter the water storage bucket 4 and preventing water resources from overflowing due to excessive storage. In other embodiments of the present disclosure, the linkage frame 5 may also be provided with an elastic reset structure, such as a spring or a buffer pad is provided at the connection between the first support 51 and the floating plate 52, to ensure that when the water level drops, the first support 51 and the second support 53 can quickly fall back to the initial position, restoring the water inlet passage of the filter pipe 63 and enabling rainwater to enter the water storage bucket 4 again for storage. The design of the linkage frame 5 realizes automatic adjustment during the rainwater storage process, without additional power drive, can dynamically adjust the water volume in the water storage bucket 4 in different precipitation environments, improve the stability of system operation and water resource utilization efficiency, and reduce maintenance requirements at the same time. In some embodiments, a warning button 55 and two telescopic rods 56 are further installed on the inner wall of the water storage bucket 4. The bottom ends of the two telescopic rods 56 are provided with a lifting plate 54, and the warning button 55 is located directly above the lifting plate 54. Among them, the warning button 55 is used to trigger a warning signal when the water level in the water storage bucket 4 reaches the set upper limit, reminding the management staff to take necessary measures, such as stopping water intake, starting drainage, or adjusting the rainwater utilization strategy. The warning button 55 is installed above the inner wall of the water storage bucket 4 and maintains an appropriate distance from the lifting plate 54 to ensure timely response when the water level changes. The warning button 55 can be a mechanical button or an electronic sensing button. The two telescopic rods 56 are installed on the inner wall of the water storage bucket 4, mainly used to support and guide the lifting plate 54, so that it moves smoothly when the water level rises, ensuring the accuracy and reliability of the process of triggering the warning button 55. When the water level in the water storage bucket 4 is normal, the lifting plate 54 is in a low position and does not touch the warning button 55, and the system remains in a standby state. When the water level gradually rises, the lifting plate 54 floats accordingly and moves upward along the trajectory of the telescopic rod 56. When the water level reaches the upper limit, the lifting plate 54 is completely lifted up and presses the warning button 55, triggering a signal to remind the staff to take measures.

[0050] Furthermore, by setting the linkage frame 5, when the water in the water storage barrel 4 is about to overflow, the buoyancy of the water is used to float the linkage frame 5 and lift up the corresponding filter tube 63 below, so that the filter tube 63 is lifted up and no water is released into the water storage barrel 4, realizing an autonomous linkage effect of shutting off water filling, and the lifting plate 54 is used to press the warning button 55 to conveniently remind the staff to replace the water storage barrel 4 in time when it overflows. Through the combined design of the warning button 55, the telescopic rod 56 and the lifting plate 54, the device can realize automatic monitoring and alarm when the water level in the water storage barrel 4 reaches the set threshold, prevent water from overflowing, improve the management efficiency of rainwater collection and storage, and reduce the workload of manual inspections, ensuring the long-term stable operation of the system.

[0051] Furthermore, the green plant trellis 1 only appears as a frame in the illustrations of the present disclosure. In actual use, baffles or access doors can be installed on the side frames of the green plant trellis 1 to form the entire green plant trellis 1 into a closed space, and transparent materials can be used on any one or more sides to ensure the lighting of the green plants inside.

[0052] Furthermore, the bottom end of the first water delivery pipe 62 is closed, and water can only be discharged through the filter pipe 63 but not from the bottom.

[0053] Furthermore, the warning button 55 is a push-type structure. After being pressed, the signal can be remotely connected to the staff's mobile phone or other signal receiver. The specific model and size can be selected according to actual conditions.

[0054] The working principle and usage of this disclosure: The device uses a green plant trellis 1 as the main body, and a photovoltaic panel 11 that can catch rainwater is installed on the top of the green plant trough 1. The rainwater is fed into a water channel 22 by gravity, and the rainwater is collected by the water channel 22 and flows into the photovoltaic panel 11. The water pipe 21 sprays the rainwater out under the action of gravity. The rainwater will fall into the bowl-shaped water inlet platform 61 through the water pipe 21, and then enter the two filter tubes 63 through the first water pipe 62 to filter out the floating dust and some harmful substances. As long as it can be used to irrigate some green plants in the power plant or as cooling water for power generation, the rainwater will then have two paths. The first path is through the sealing ring 72, the second water pipe 73, the water storage pipe 31, the sprinkler pipe 32, and then through the sprinkler head 33 to irrigate the green plants. The second path is through the sealing ring 72 and the third water pipe 75 to enter the water storage barrel 4 to store the rainwater. However, there are certain conditions for entering the above two paths: Because of the sliding support of the sliding ring 64 and the positioning rod 67, in conjunction with the sliding support of the first water pipe 62 through the sliding ring 64 and the photovoltaic panel 11, the entire first water pipe 62 can drive the filter pipe 63 to move up and down.

[0055] In the initial state, when the water inlet platform 61 is not subjected to any impact and there is no rainwater inside, the upper filter tube 63 and the lower filter tube 63 will form a closed state with the partition 71, which can also prevent dust and impurities from entering the water storage barrel 4 or the rainwater irrigation component 3.

[0056] When it rains lightly, rainwater will fall through the photovoltaic panel 11, the water trough 22, and the water pipe 21 without impacting the water inlet platform 61. However, the water flow in the first water pipe 62 has weight at this time, which will drive the first water pipe 62 to move downward. After being filtered by the filter element 65, it will take the first route. At this time, the water valve 74 is opened, and the rainwater is poured into the water storage pipe 31 through the second water pipe 73, and then enters the sprinkler pipe 32 and is finally poured into the green plants planted in the green plant pot 12 through the sprinkler head 33.

[0057] When it rains moderately, the rain will not only be heavier, but also have a certain impact on the water inlet platform 61. At this time, the two filter tubes 63 will be connected to the two sealing rings 72 respectively. At this time, when the water valve 74 is opened, water will be supplied to the rainwater irrigation component 3 and the water storage barrel 4 through the first and second lines at the same time.

[0058] When it rains heavily or rainstorms occur, the rain is heavier and the impact force is greater. At this time, the first water pipe 62 moves downward to compress the spring 66 until the spring 66 shrinks to its limit. At this time, only the upper filter tube 63 enters the second path through the sealing ring 72 to supply water to the water storage barrel 4, while the lower filter tube 63 will be blocked in cooperation with the second water delivery component 7, and only the water source is stored in the water storage barrel 4.

[0059] In addition to the above-mentioned situations, there is another weather condition. When water is continuously stored inside the water storage barrel 4, the water level will rise until the float plate 52 can be lifted up. At this time, the float plate 52 will drive the first bracket 51 and the second bracket 53 to move upward. When the water level in the water storage barrel 4 reaches the limit, the first bracket 51 and the float plate 52 will be forced to link the second bracket 53 to lift the filter tube 63 to forcibly close the second path. At this time, the lifting plate 54 on the telescopic rod 56 will move to the top to press the warning button 55. The warning button 55 will remotely transmit the signal to the staff for timely replacement because the top of the water storage barrel 4 can be opened, and the rest of the parts are integrated on the cover, or a water outlet can be added at the bottom of the side of the water storage barrel 4 to divert the water flow.

[0060] In the dry season, the water pump 8 can also be actively started to pump water from the water storage barrel 4 and directly introduce it into the rainwater irrigation assembly 3, and supply water to the green plants in the green plant pot 12 through the water storage pipe 31, the spray pipe 32 and the spray head 33.

[0061] In addition, in other embodiments of the present disclosure, when the plants in the green plant pot 12 do not need to be watered frequently, the water pump 8 can be directly removed, and the whole only needs to supply water to the plants in the green plant pot 12 on rainy days, effectively reducing the cost of the overall system and not affecting the normal operation of the device.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations. In addition, in the description of the present disclosure, unless otherwise stated, the meaning of "a plurality of" is two or more.
