[0001] This application relates to the field of photovoltaic desertification control technology, and in particular to a desertification control device and a photovoltaic desertification control system. Background Technology

[0002] In recent years, with the increasing severity of problems such as water scarcity, soil salinization, and wind erosion, desertification has become increasingly serious, making its control an urgent priority. Photovoltaic desertification control has been widely applied and promoted because it can achieve a coordinated balance of ecological, economic, and social benefits.

[0003] The most distinctive feature of photovoltaic desertification control is that it combines the development of photovoltaic power with desert management, achieving the effect of preventing and controlling desertification through planting vegetation. However, the survival rate of plants in the desert is low, affecting the efficiency of desertification control. Summary of the Invention

[0009] The permeation conduit runs through the side wall of the box and is connected to the water supply pipeline. The part of the permeation conduit that extends out of the box is buried in the sand layer, and the outlet end of the permeation conduit extends to the vicinity of the root system of the plants in the planting area.

[0010] When multiple boxes are assembled, the water supply pipes in each box are interconnected, and the inlet of one of the water supply pipes is connected to an external water source.

[0011] In one possible implementation, the water-retaining layer includes a fertilizer layer, a coarse sand layer, a fine sand layer, and a clay layer. The coarse sand layer is located on the side of the fertilizer layer facing the planting area, the fine sand layer is located on the side of the coarse sand layer facing the planting area, and the clay layer is located on the side of the fine sand layer facing the planting area.

[0012] The second end of the branch pipe extends into the fertilizer layer.

[0013] In one possible implementation, the main body of the branch pipe section is provided with a bend.

[0014] In one possible implementation, the desertification control device also includes a rain collection component, which includes a rain collection umbrella and a first rain guide pipe. One end of the first rain guide pipe extends into the box and is connected to the water supply pipeline. The rain collection umbrella is positioned above the box and connected to the first rain guide pipe. The rainwater collected by the rain collection umbrella can be introduced into the water supply pipeline through the first rain guide pipe.

[0015] In one possible implementation, the rain collection assembly also includes a canopy, which is installed at the other end of the first rain guide tube and communicates with the first rain guide tube. A rain collection umbrella is disposed between the canopy and the housing, with the edge of the rain collection umbrella extending beyond the canopy. The first rain guide tube passes through the rain collection umbrella and has holes on its side wall for rainwater to enter the rain collection umbrella.

[0016] In one possible implementation, the rain collection assembly also includes a second rain guide pipe, which is arranged in a winding manner inside the housing. One end of the second rain guide pipe is connected to one end of the first rain guide pipe, and the other end of the second rain guide pipe is connected to the water supply pipeline.

[0017] In one possible implementation, a check valve is installed between the second rain pipe and the water supply pipe.

[0018] According to another aspect of the embodiments of this application, a photovoltaic desertification control system is provided, including a water supply module and the aforementioned plurality of desertification control devices;

[0019] Multiple desertification control devices are spliced ​​together to define the planting area;

[0020] The water supply module includes an irrigation tank, a water supply station, a water pump, and a monitoring module. The irrigation tank is connected to the water supply station via a pipeline, the water pump is connected in series to the pipeline, and a switch valve is installed on the pipeline.

[0023] The desertification control device provided in this application incorporates a water-retaining layer on the side of the housing facing the planting area. When the water supply pipeline is connected to an external water source, some water from the pipeline flows into the water-retaining layer and then infiltrates into the surrounding sand. Additionally, some water from the pipeline can directly supply moisture to the plants in the planting area via infiltration conduits. Thus, when multiple desertification control devices are interconnected, they not only act as a barrier against sand and soil but also provide the plants with the necessary water for growth, increasing their survival rate in the desert and thereby improving the efficiency of desertification control.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0042] Currently, the survival rate of plants in the desert is low, affecting the efficiency of desertification control. This is due to factors such as water scarcity, high ambient temperatures, and inadequate water conservation measures in the desert.

[0043] After repeated consideration and verification, the inventors of this application discovered that if a sand control device is designed, multiple sand control devices can be interconnected and arranged around a planting area. The sand control device includes a water supply pipeline that can connect to an external water source, and a seepage conduit connected to the water supply pipeline. The outlet end of the seepage conduit extends to the vicinity of the plant roots within the planting area. Water can be supplied to the plants in the planting area through the water supply pipeline and the seepage conduit. Furthermore, the side of the sand control device facing the planting area is designed as a water-retaining layer. Some water from the water supply pipeline can flow to the water-retaining layer and then seep into the sand surrounding the sand control device, thus retaining water. In this way, the sand control device not only blocks sand but also improves the survival rate of plants in the desert.

[0044] In view of this, the inventors of this application have designed a desertification control device, including a box, a water supply pipeline, and an infiltration conduit. Part of the box is embedded in the sand layer, and the wall of the box facing the planting area is a water-retaining layer. The water supply pipeline inside the box can deliver water to the water-retaining layer and the infiltration conduit respectively. The infiltration conduit can directly supply water to the plants in the planting area, and the water-retaining layer can improve the water retention of the planting area. Using this desertification control device can improve the survival rate of plants in the desert.

[0045] The technical solutions of the desertification control device and photovoltaic desertification control system provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0046] Reference Figures 1-5As shown, this application embodiment provides a sand control device 100. Multiple sand control devices 100 can be spliced ​​together to enclose and define a planting area 200. The sand control device 100 includes a box body 110, a water supply pipeline 120, a branch pipe section 130, and a seepage conduit 140. The box body 110 is configured to be partially buried in the sand layer, and the side wall of the box body 110 facing the planting area 200 is a water-retaining layer 111. The water supply pipeline 120 is disposed inside the box body 110, and the first end of the branch pipe section 130 is connected to the water supply pipeline 120, and the second end extends into the water-retaining layer 111. The seepage conduit 140 penetrates the side wall of the box body 110 and is connected to the water supply pipeline 120. The portion of the seepage conduit 140 extending out of the box body 110 is configured to be buried in the sand layer, and the outlet end of the seepage conduit 140 extends to the vicinity of the root system of the plants in the planting area 200. When multiple boxes 110 are spliced ​​together, the water supply pipes 120 in each box 110 are interconnected, and the inlet of one of the water supply pipes 120 is connected to an external water source.

[0047] Schematic illustration: Multiple sand control devices 100 can be spliced ​​together to form a ring structure, which surrounds the planting area 200. For example, the ring structure can be rectangular, with the splicing surfaces of adjacent sand control devices 100 joined together at the four corners by bevels. In connecting multiple sand control devices 100, trenches can be dug on the site first, each sand control device 100 placed in the trench, and adjacent devices 100 spliced ​​and fixed. After splicing, the trench is filled, burying part of the box 110 in the sand layer. The portion of the box 110 above the sand layer can act as a shield against the sand. For example, the sand control device 100 can be made of biodegradable materials such as bamboo powder biodegradable material.

[0048] In one possible implementation, a support structure can be provided inside the housing 110 to fix the water supply pipe 120 inside the housing 110. For example... Figure 3 and Figure 5As shown, the water supply pipeline 120 is provided with an inlet and an interface 121 exposed from the housing 110, with the interface 121 located on the splicing surface of the housing 110. When multiple desertification control devices 100 are spliced ​​together, the inlet of the water supply pipeline 120 in one of the desertification control devices 100 can be connected to an external water source, and the interface 121 of the water supply pipeline 120 can be connected to the inlet of the water supply pipeline 120 in another desertification control device 100. It is worth mentioning that the number of interfaces 121 of the water supply pipeline 120 can be one or multiple. When the water supply pipeline 120 is provided with multiple interfaces 121, the water supply pipeline 120 in the desertification control device 100 connected to the external water source is provided with only one inlet, while the water supply pipelines 120 in the other desertification control devices 100 can be provided with multiple inlets and outlets. When the housings 110 of two adjacent desertification control devices 100 are spliced ​​together, the interface 121 of the water supply pipeline 120 of one desertification control device 100 is closely connected to the inlet of the water supply pipeline 120 of the other desertification control device 100.

[0049] like Figure 3 and Figure 4 As shown, for example, the first end of the branch pipe section 130 can be connected to point A of the water supply pipe 120. The thickness of the water-retaining layer 111 can be set as needed and is not limited here.

[0050] The number of seepage conduits 140 is not limited, and those skilled in the art can set them as needed, without making a unique limitation here. One end of the seepage conduit 140 is connected to the water supply pipe 120, and the other end of the seepage conduit 140 passes through the side wall of the bottom of the tank. Figure 2 and Figure 3 As shown, a water infiltration element 141 is installed at one end of the water infiltration conduit 140 away from the water supply pipe 120. The water infiltration element 141 is a spherical structure with small holes, through which water is supplied to the plants in the planting area 200.

[0051] The desertification control device 100 provided in this application embodiment has a water-retaining layer 111 on the side of the housing 110 facing the planting area 200. When the water supply pipeline 120 is connected to an external water source, some of the water in the pipeline 120 can flow to the water-retaining layer 111 and infiltrate into the sand around the device. In addition, some of the water in the pipeline 120 can also directly supply water to the plants in the planting area 200 via the infiltration conduit 140. Thus, when multiple desertification control devices 100 are connected together, they not only act as a barrier against sand but also provide the plants in the planting area 200 with the necessary water for growth, improving the survival rate of plants in the desert and thereby increasing the efficiency of desertification control.

[0052] Furthermore, the desertification control device 100 provided in this application embodiment has strong site adaptability. Multiple desertification control devices 100 can be assembled as needed, and the connection speed of multiple desertification control devices 100 is relatively fast. By supplying water to the plants in the planting area 200, the desertification control device 100 can achieve a relatively long desertification control cycle.

[0053] In one embodiment, such as Figure 4 and Figure 6 As shown, the water-retaining layer 111 includes a fertilizer layer 1111, a coarse sand layer 1112, a fine sand layer 1113, and a clay layer 1114. The coarse sand layer 1112 is located on the side of the fertilizer layer 1111 facing the planting area 200, the fine sand layer 1113 is located on the side of the coarse sand layer 1112 facing the planting area 200, the clay layer 1114 is located on the side of the fine sand layer 1113 facing the planting area 200, and the second end of the branch pipe section 130 extends into the fertilizer layer 1111.

[0054] The fertilizer in the fertilizer layer 1111 can be organic fertilizer. In one possible implementation, multiple layers of support netting can be installed on the housing 110, with the fertilizer layer 1111, coarse sand layer 1112, fine sand layer 1113, and clay layer 1114 positioned between adjacent layers of support netting, supporting each layer in the water-retaining layer 111. Those skilled in the art can adjust the thickness of each layer as needed; no single thickness is specified here. When the branch pipe section 130 delivers water into the fertilizer layer 1111, the water in the fertilizer layer 1111 can permeate through the coarse sand layer 1112 and the fine sand layer 1113, finally seeping into the clay layer 1114. Once the clay layer 1114 has absorbed sufficient water, it can provide nutrient-rich water to the plants in the planting area 200.

[0055] This structure, comprising a fertilizer layer 1111, a coarse sand layer 1112, a fine sand layer 1113, and a clay layer 1114, ensures that the water-retaining layer 111 has sufficient water retention capacity and allows water to permeate from the fertilizer layer 1111 into the clay layer 1114. This allows the water-retaining layer 111 to provide nutrient-rich water to the plants within the planting area 200, providing them with the necessary nutrients and water for growth. Understandably, within the planting area 200, as the plants grow, their roots extend outwards, eventually penetrating into the clay layer 1114. It is worth noting that when using a support net to support the water-retaining layer 111, the net can be made of biodegradable materials, ensuring that it does not obstruct the roots from entering the clay layer 1114. As the roots penetrate the clay layer 1114 and become thicker, more nutrient-rich water seeps out from it. With the above setup, before the plants in the planting area 200 have the function of preventing wind and controlling sand, the sand control device 100 can provide the plants with nutrients and water to help them grow vigorously; the sand control device 100 can supply water to the plants in real time according to their growth, without the need for manual monitoring of crop growth, and can reduce water waste and lower the cost of plant cultivation.

[0056] In a specific embodiment, such as Figure 4 As shown, the main body of the branch pipe section 130 is provided with a bend section 131. The number of bend sections 131 is not limited and is not specified here. By providing bend sections 131, the impact of water in the branch pipe section 130 on the water-retaining layer 111 can be reduced, which helps to improve the service life of the water-retaining layer 111.

[0057] In one embodiment, such as Figure 2 and Figure 3 As shown, the desertification control device 100 also includes a rain collection component 150. The rain collection component 150 includes a rain collection umbrella 151 and a first rain guide pipe 152. One end of the first rain guide pipe 152 extends into the housing 110 and is connected to the water supply pipe 120. The rain collection umbrella 151 is located above the housing 110 and is connected to the first rain guide pipe 152. The rainwater collected by the rain collection umbrella 151 can be introduced into the water supply pipe 120 through the first rain guide pipe 152.

[0058] The first rain guide tube 152 can extend vertically, and the position of the first rain guide tube 152 near the bottom can be fixed to the top wall of the box 110. The first rain guide tube 152 can pass through the center of the rain collection umbrella 151. Figure 2 and Figure 3As shown, the edge of the rain collecting umbrella 151 is higher than the center. During rainy weather, the rain collecting umbrella 151 can guide rainwater to flow towards the first rain guide 152. Holes for rainwater to enter can be opened on the side wall of the first rain guide 152. It is understood that there can be one or more rain collecting umbrellas 151. When there are multiple rain collecting umbrellas 151, they are arranged vertically at intervals, and the area of ​​the lower rain collecting umbrella 151 is larger than the area of ​​the upper rain collecting umbrella 151, so that the edge of the lower rain collecting umbrella 151 extends beyond the upper rain collecting umbrella 151.

[0059] In one possible implementation, there can be multiple first rain guide tubes 152, each of which is equipped with a rain collection umbrella 151 and is connected to the water supply pipeline 120.

[0060] This structure utilizes a rain-collecting umbrella 151 to collect rainwater, which is then channeled into a water supply pipe 120 via a first rain guide pipe 152, thus conserving water. Furthermore, when it is not raining, the rain-collecting umbrella 151 provides shade, reducing water evaporation near the sand control device 100 and sunlight exposure to the plants. This reduces water evaporation from the plants and the surrounding sand, improving the water retention capacity of the sand control device 100, enhancing the plant's entropy retention effect, and further increasing the plant's survival rate.

[0061] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the rain collection assembly 150 also includes a canopy 153. The canopy 153 is installed at the other end of the first rain guide tube 152 and communicates with the first rain guide tube 152. The rain collection umbrella 151 is disposed between the canopy 153 and the housing 110. The edge of the rain collection umbrella 151 extends beyond the canopy 153, and the first rain guide tube 152 is disposed through the rain collection umbrella 151. The side wall of the first rain guide tube 152 is provided with holes for rainwater to enter the rain collection umbrella 151.

[0062] Specifically, the canopy 153 is installed at the top of the first rain guide 152, and the canopy 153 has a through hole communicating with the first rain guide 152. The height of the edge of the canopy 153 is higher than the height of the connection point between the canopy 153 and the first rain guide 152. In rainy weather, the canopy 153 can also collect rainwater and guide it into the first rain guide 152.

[0063] For example, there can be multiple holes, which can be arranged around the first rain guide tube 152. It is understood that the projected area of ​​the rain collecting umbrella 151 in the height direction of the housing 110 is greater than the projected area of ​​the canopy 153 in the height direction of the housing 110.

[0064] This structure, by setting up a canopy 153, increases the projected area of ​​the rain-collecting component 150 in the vicinity when there is no rainfall, further improving the water retention function of the sand control device 100, thereby further improving the survival rate of plants. During rainy weather, the canopy 153 can also collect rainwater. Furthermore, the edge of the rain-collecting umbrella 151 extends beyond the canopy 153, ensuring that the rain-collecting umbrella 151 can collect more rainwater.

[0065] In a more specific embodiment, such as Figure 3 As shown, the rain collection assembly 150 also includes a second rain guide pipe 154, which is arranged in a winding manner inside the housing 110. One end of the second rain guide pipe 154 is connected to one end of the first rain guide pipe 152, and the other end of the second rain guide pipe 154 is connected to the water supply pipeline 120.

[0066] Indicatively, the second rain guide 154 can be integrally formed with the first rain guide 152. After the rain collection umbrella 151 and the canopy 153 guide rainwater into the first rain guide 152, the rainwater in the first rain guide 152 can enter the water supply pipeline 120 through the second rain guide 154.

[0067] This structure, by setting a second rain guide pipe 154 and setting the second rain guide pipe 154 in a meandering manner inside the box 110, can increase the rainwater storage capacity of the sand control device 100 when the rainfall is large, thereby further reducing the use of external water resources.

[0068] Optionally, a check valve is provided between the second rain guide pipe 154 and the water supply pipe 120. This embodiment does not limit the specific structure of the check valve; those skilled in the art can select a suitable check valve according to actual needs.

[0069] With this structure, when an external water source enters the water supply pipeline 120, the one-way valve can prevent water from entering the second rain guide pipe 154 from the water supply pipeline 120, and prevent the second rain guide pipe 154 from affecting the water supply pipeline 120 in delivering water to the water-retaining layer 111 and the seepage conduit 140; during rainy weather, water in the second rain guide pipe 154 can enter the water supply pipeline 120 through the one-way valve.

[0070] like Figure 1 As shown, this application also provides a photovoltaic desertification control system, including a water supply module and the aforementioned multiple desertification control devices 100. The multiple desertification control devices 100 are interconnected and define a planting area 200. The water supply module includes an irrigation tank 330, a water supply station 340, a water pump, and a monitoring module. The irrigation tank 330 is connected to the water supply station 340 via a pipeline. The water pump is connected in series to the pipeline, and a switch valve 360 ​​is installed on the pipeline. The monitoring module is electrically connected to the water pump and is configured to acquire the water volume in the irrigation tank 330 and control the start and stop of the water pump.

[0071] Understandably, when multiple desertification control devices 100 are connected together, the inlet of the water supply pipeline 120 of one of the desertification control devices 100 can be connected to the irrigation tank 330 via a pipe. For example, a pump can be configured to drive water from the irrigation tank 330 into the water supply pipeline 120 of the desertification control device 100 through a pipe; alternatively, the end of the pipe connected to the irrigation tank 330 can be higher than the end connected to the desertification control device 100, allowing water from the irrigation tank 330 to flow by gravity into the water supply pipeline 120 of the desertification control device 100 via a pipe.

[0072] For example, such as Figure 1 As shown, the pipeline includes a main water supply pipe 351 and a branch water supply pipe 352. One end of the main water supply pipe 351 is connected to the water supply station 340, and the other end of the main water supply pipe 351 is connected to one end of the branch water supply pipe 352. The other end of the branch water supply pipe 352 is connected to the irrigation tank 330. A switch valve 360 ​​can be installed on the branch water supply pipe 352 to control the connection between the water supply station 340 and the irrigation tank 330.

[0073] In one possible implementation, the monitoring module is electrically connected to both the water pump and the switching valve 360. When the monitoring module detects insufficient water in the irrigation tank 330, it can control both the water pump and the switching valve 360 ​​to open, allowing the water pump to draw water from the water supply station 340 into the irrigation tank 330. When the monitoring module detects that the water level in the irrigation tank 330 has reached a preset level, it can control the switching valve 360 ​​and the water pump to close.

[0074] With this structure, the water supply station 340 can automatically replenish the irrigation tank 330 according to the water volume in the irrigation tank 330, eliminating the need for manual inspection of the irrigation tank 330 and thus reducing labor costs.

[0075] In one embodiment, such as Figure 1 As shown, the water supply module also includes a rainwater collection box 320 and a rainwater collection trough 310. The rainwater collection trough 310 is installed on the photovoltaic module 500, and the rainwater collection box 320 is connected to the rainwater collection trough 310. The rainwater collection box 320 is connected to the irrigation tank 330 via a pipeline, and the rainwater collection box 320 is connected to the water supply station 340 via a pipeline. Water in the rainwater collection box 320 and the irrigation tank 330 can flow into the water supply station 340 by gravity via the pipeline, and a water pump is configured to drive water in the water supply station 340 into the water supply station 340 and the irrigation tank 330 via the pipeline.

[0076] For example, the rainwater collection trough 310 can be a long strip structure with a U-shaped cross-section. One rainwater collection trough 310 can be connected to multiple photovoltaic modules 500 in a row. The rainwater collection trough 310 is installed at the bottom of the photovoltaic panel of the photovoltaic module 500. When it rains, the photovoltaic panels of each photovoltaic module 500 can guide rainwater into the rainwater collection trough 310, and the rainwater in the rainwater collection trough 310 can enter the rainwater collection box 320 through pipes.

[0077] For example, the pipeline includes a main water supply pipe 351 and multiple branch water supply pipes 352, one of which is connected to an irrigation tank 330, and the remaining branch water supply pipes 352 are connected to rainwater collection tanks 320 one by one. Figure 1 As shown, a switch valve 360 ​​is installed on the branch water supply pipe 352 connected to the rainwater collection tank 320. In one possible implementation, the end of the pipeline connected to the water supply station 340 is at a lower height than the end connected to the irrigation tank 330 and the end connected to the rainwater collection tank 320. When the rainfall is heavy, the switch valves 360 on the pipeline can be opened, allowing water in the irrigation tank 330 and the rainwater collection tank 320 to flow back into the water supply station 340 through the pipeline.

[0078] Through the above setup, the photovoltaic desertification control system can collect and utilize rainwater, thereby achieving water conservation.

[0079] In one embodiment, such as Figure 1 As shown, the monitoring module includes a water volume monitor 430 installed in the irrigation tank 330, a first pressure gauge 410 installed on the pipeline, and a controller (not shown). The water volume monitor 430, the first pressure gauge 410, the water pump, and the switch valve 360 ​​are electrically connected to the controller.

[0080] Figure 1 As shown, a first pressure gauge 410 is installed on a branch water supply pipe 352 connected to the irrigation tank 330. A switch valve 360 ​​on this branch water supply pipe 352 is located on the side of the first pressure gauge 410 away from the irrigation tank 330. When the switch valve 360 ​​is closed, the first pressure gauge 410 can detect the pressure inside the irrigation tank 330. When the switch valve 360 ​​is open, the first pressure gauge 410 can detect the liquid pressure in the pipeline between the water supply station 340 and the irrigation tank 330, preventing excessive liquid pressure in the pipeline when the water supply station 340 replenishes liquid into the irrigation tank 330, which could damage the pipeline. It is understood that the water volume monitor 430 can detect the water volume in the irrigation tank 330. This embodiment does not limit the specific structure of the water volume monitor 430 and the first pressure gauge 410; those skilled in the art can select a suitable first pressure gauge 410 and water volume monitor 430 according to actual needs.

[0081] In this embodiment, the first pressure gauge 410 can detect the pressure in the irrigation tank 330, and the water volume monitor 430 can detect the water volume in the irrigation tank 330. When the water volume or pressure in the irrigation tank 330 is low, the controller can control the water pump and the corresponding switch valve 360 ​​to open, and water from the water supply station 340 enters the irrigation tank 330 under the drive of the water pump. When the water volume and pressure in the irrigation tank 330 reach preset values, the control box controls the water pump and switch valve 360 ​​to close, and the water supply station 340 stops supplying water to the irrigation tank 330. When there is heavy rainfall causing the water volume and pressure in the irrigation tank 330 to exceed the preset values, the controller can control the switch valve 360 ​​to open, and the water in the rainwater collection tank 320 and the irrigation tank 330 flows back to the water supply station 340 via pipeline by gravity. Through the above settings, it can be ensured that the water volume and pressure in the irrigation tank 330 meet the irrigation requirements of the plants in the planting area 200.

[0082] Optional, such as Figure 1 As shown, a second pressure gauge 420 is installed on the branch water supply pipe 352 connected to the rainwater collection tank 320. The second pressure gauge 420 is electrically connected to the controller. The pressure in the rainwater collection tank 320 can be detected by the second pressure gauge 420. The controller can control the working status of the water pump and the corresponding switch valve 360 ​​according to the signal transmitted by the second pressure gauge 420, so that the water supply station 340 replenishes water to the rainwater collection tank 320.

[0083] Optional, such as Figure 1 As shown, a flushing valve 370 is installed on the pipeline. The pipeline can be flushed through the flushing valve 370 to ensure that the pipeline is unobstructed.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
