[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0037] Photovoltaic power generation is a rapidly developing clean energy technology, especially suitable for areas rich in solar energy resources such as deserts, Gobi and wasteland. Since photovoltaic arrays can reduce near-surface wind speeds, the shading of photovoltaic components can reduce surface temperature and reduce soil moisture evaporation, which invisibly provides a good environment for plant seed germination and seedling growth. Planting plants in the surface area near photovoltaic components can improve soil quality and soil quality, and realize the integrated development of ecological governance and photovoltaic power generation, agriculture, forestry and animal husbandry and other industries.

[0038] At present, for plants in the surface area near photovoltaic components, the photovoltaic components themselves are not very effective in recycling water, and external water needs to be regularly delivered for irrigation. However, the cost of frequently delivering water to irrigate plants is high, which is not conducive to the sustainable development of plant cultivation.

[0039] Based on the above problem description, one or more embodiments of the present application provide a photovoltaic irrigation system, in which a first irrigation area is set below the photovoltaic component, and a water storage unit is set on one side of the first irrigation area. Since the first irrigation area is configured to receive water flowing through the photovoltaic component, when the photovoltaic component is washed and cleaned regularly on rainy and snowy days, the water on the photovoltaic component will enter the first irrigation area to irrigate the first irrigation area, and the excess water will enter the water storage unit through the first irrigation area. In dry periods, the water in the water storage unit can be re-transported to the first irrigation area for irrigation, and the original water in the photovoltaic component can be used to irrigate the plants, realizing agricultural and light complementarity, reducing the frequency and amount of irrigation water transported separately, effectively improving the utilization effect of water resources, and reducing water resource consumption.

[0040] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] Reference Figure 1The photovoltaic irrigation system of the embodiment of the present application includes a photovoltaic device, a first irrigation area 201, a water storage unit 300 and a conveying unit, wherein the first irrigation area 201 is arranged on one side of the photovoltaic device, the first irrigation area 201 is used to plant water purification plants, and the first irrigation area 201 is configured to receive water flowing through the photovoltaic device; the water storage unit 300 is arranged on one side of the first irrigation area 201 to collect the water flowing through the first irrigation area 201; the conveying unit connects the water storage unit 300 and the first irrigation area 201, and the water storage unit 300 conveys water to the first irrigation area 201 through the conveying unit.

[0042] The photovoltaic element described above can be a single photovoltaic panel 100, or a photovoltaic matrix composed of a plurality of photovoltaic panels 100 extending at intervals. Exemplarily, the photovoltaic element includes a plurality of photovoltaic panels 100 extending in a certain direction, and the first irrigation area 201 is arranged on one side of the photovoltaic panel 100. When it rains or snows or when washing dust off the photovoltaic panel 100, the accumulated water on the photovoltaic panel 100 will drip along the side end of the photovoltaic panel 100 into the first irrigation area 201, so that the first irrigation area 201 can recycle the water.

[0043] Furthermore, a water outlet weir 101 is provided at the lower end of the photovoltaic panel 100, and the water outlet weir 101 extends along the length direction of the photovoltaic component. The water outlet weir 101 is used to guide the water on the photovoltaic component to the first irrigation area 201. Here, the photovoltaic panel 100 is arranged obliquely, and the water outlet weir 101 is arranged on the lower side of the photovoltaic panel. Exemplarily, the water outlet weir 101 includes a fixed portion fixed to the side end of the photovoltaic panel 100, and a guiding portion protruding relative to the photovoltaic panel 100, the guiding portion is smoothly bent relative to the fixed portion, and the bending direction of the guiding portion is toward the first irrigation area 201, and the water on the photovoltaic panel 100 flows down along the panel surface and is guided by the water outlet weir 101 to drip into the first irrigation area 201.

[0044] In some embodiments, illustratively, the water purification plants planted in the first irrigation area 201 are drought-resistant plants such as ryegrass and pennisetum. Plants such as ryegrass and pennisetum are cold-resistant, drought-resistant, and have strong stress resistance, and have a well-developed root system. They can adapt to the semi-hidden environment under the photovoltaic panel 100, and are also conducive to the formation of a plant retention area in the first irrigation area 201. After the water enters the first irrigation area 201, the rhizosphere action of plants such as ryegrass or pennisetum and the action of soil microorganisms can remove impurities such as suspended matter, heavy metals and nutrients in the water, thereby purifying the water. Here, it should be noted that for different regions, the types of water purification plants actually planted are also different. The types of water purification plants are determined according to relevant factors such as the planting environment, region, and soil composition.

[0045] The photovoltaic irrigation system further includes a water filtering unit 203 , which is connected to the first irrigation area 201 and the water storage unit 300 . The water filtering unit 203 is configured to filter the water in the first irrigation area 201 .

[0046] like Figure 1 As shown, Figure 1 The middle dotted line represents the ground plane, the water filtering unit 203 is located below the first irrigation area 201, the water storage unit 300 has a liquid inlet, and a water outlet is provided below the water filtering unit 203, and the water outlet is connected to the liquid inlet. Here, the water liquid uses its own gravity to penetrate downward, and the water liquid first passes through the water filtering unit 203 and then enters the water storage unit 300, and the water filtering unit 203 further filters the water liquid.

[0047] Reference Figure 1 As shown, illustratively, the water filter unit 203 includes at least two water filter layers stacked in a vertical direction, the water filter layers contain filter gravels, and the particle sizes of the filter gravels in any two adjacent water filter layers are different.

[0048] In the above embodiment, at least two water filtration layers include a crushed stone layer 2031, a pebble layer 2032 and a gravel layer 2033, and the crushed stone layer 2031 is arranged adjacent to the first irrigation area 201. The crushed stone layer 2031 is a crushed stone with a smaller particle size, which plays a role in supporting the upper planting soil and water permeability; the pebble layer 2032 is a pebble with a medium particle size, which plays a role in supporting the upper crushed stone layer 2031 and water permeability; the gravel layer 2033 is a gravel with a larger particle size, which plays a role in supporting the upper pebble and temporarily storing water, and the pebble layer 2032 is sandwiched between the crushed stone layer 2031 and the gravel layer 2033, and the pebble layer 2032 can support the upper crushed stone layer 2031 and provide filtering space.

[0049] For example, the particle size of the crushed stones in the crushed stone layer 2031 is 5-10 mm, and the thickness of the crushed stone layer 2031 is 300 mm, the particle size of the pebbles in the pebble layer 2032 is 10-20 mm, and the thickness of the pebble layer 2032 is 300 mm, the particle size of the gravel in the gravel layer 2033 is 5-10 mm, and the thickness of the gravel layer 2033 is 700 mm. The thickness of the gravel layer 2033 is greater than the thickness of other water filtering layers, thereby, the infiltrated water can be temporarily stored in the gravel layer 2033, so that the water of the subsequent water filtering unit 203 can be collected and entered into the water storage unit 300. Of course, the water filtering layer of the water filtering unit 203 in the embodiment of the present application is only used as an example, and the actual composition and particle size selection of the water filtering layer can be flexibly set.

[0050] In the above embodiment, the gravel layer 2031 is located at the top layer, and the gravel layer 2031 is adjacent to the bottom of the first irrigation area 201. In order to ensure the stable planting of water purification plants in the first irrigation area 201, a planting soil layer 204 and a soil cover layer 205 are laid in the first irrigation area 201. The planting soil layer 204 is laid above the gravel layer 2031, and the thickness is not less than 500 mm. The soil cover layer 205 is located above the soil planting layer. The roots of the water purification plants are planted in the planting soil layer 204. The planting soil layer 204 is composed of topsoil and organic matter, and the soil cover layer 205 is made of bark, hay, pine needles and other materials. The soil cover layer 205 can cover the planting soil to prevent the water dripping from the photovoltaic panel 100 in the first irrigation area 201 from evaporating and losing.

[0051] In some embodiments, reference Figure 1 As shown, the photovoltaic irrigation system of the embodiment of the present application also includes an anti-leakage trough 202, in which the water filtering unit 203 and the first irrigation area 201 are arranged. The liquid inlet of the water storage unit 300 is provided with a connecting pipe 301, and the connecting pipe 301 extends into the anti-leakage trough 202 to collect the water filtered by the water filtering unit 203. The anti-leakage trough 202 can ensure that the water entering the first irrigation area 201 is fully recovered to prevent the loss of water.

[0052] In the above embodiment, the anti-leakage trough 202 is preferably made of concrete material, and an opening is provided on one side of the bottom end of the anti-leakage trough 202, and the connecting pipe 301 is connected to the opening after being inserted into the anti-leakage trough 202. Further, the opening is located in the middle of the bottom of the anti-leakage trough 202, and the bottom of the anti-leakage trough 202 is gradually concave toward the middle, and the opening is at the lowest point of the bottom of the trough, so that the water filtered by the water filter layer can be guided into the opening at the bottom of the trough, so that the water storage unit 300 can collect the water.

[0053] The water storage unit 300 in the embodiment of the present application can be a buried PE (Polyethylene) tank or a fiberglass tank. The water storage unit 300 is buried in the underground area. On the one hand, it prevents the high temperature of the external environment from evaporating the water in the water storage unit 300, and on the other hand, it can make full use of the gravity difference to collect the water in the first irrigation area 201.

[0054] It should be noted that, in some embodiments, the water storage unit 300 is further provided with an external liquid inlet, and external water can be used to transport water to the water storage unit 300 through the external liquid inlet. Here, the external liquid inlet is connected through a pipeline and extends out of the ground, and the external water can be connected to the water storage unit 300 by connecting with the pipeline and directly supplying water to the water storage unit 300. This arrangement can facilitate the water storage unit 300 to store external water, so that the external water can temporarily transport water to irrigate plants in a long-term drought environment.

[0055] Reference Figure 1 As shown, in some embodiments, the photovoltaic irrigation system also includes a second irrigation area 400, which is arranged on one side of the first irrigation area 201; the delivery unit includes a first delivery pipeline 501 for connecting the first irrigation area 201 and the water storage unit 300, and a second delivery pipeline 502 for connecting the second irrigation area 400 and the water storage unit 300, and the water storage unit 300 delivers water to the second irrigation area 400 through the second delivery pipeline 502.

[0056] The above-mentioned second irrigation area 400 is also provided with a planting soil layer 204 and a soil covering layer 205 . The planting soil layer 204 is laid above the soil surface layer with a thickness of not less than 500 mm. The soil covering layer 205 is located above the soil planting layer. The roots of the plants in the second irrigation area 400 are planted in the planting soil layer 204 .

[0057] Illustratively, in the above-mentioned embodiment, the first delivery pipeline 501 and the second delivery pipeline 502 can be made of polyvinyl chloride (Unplasticized Polyvinyl Chloride, UPVC) material. After the first delivery pipeline 501 is connected to the first irrigation area 201, it extends along the length direction of the first irrigation area 201. After the second delivery pipeline 502 is connected to the second irrigation area 400, it extends along the length direction of the second irrigation area 400. A plurality of sprinkler heads 503 and drip irrigation nozzles are arranged on the first delivery pipeline 501 and the second delivery pipeline 502. The sprinkler heads 503 and the drip irrigation nozzles are connected in parallel on the delivery pipeline. The irrigation mode of sprinkler irrigation or drip irrigation is switched by external control to realize irrigation of the first irrigation area 201 and the second irrigation area 400.

[0058] In the above embodiment, crops or trees and other plants are planted in the second irrigation area 400. The water quality requirements of the plants in the second irrigation area 400 are higher than those of the plants in the first irrigation area 201. The plants in the second irrigation area 400 receive the filtered water from the water storage unit 300. Generally, the water storage unit 300 is connected to a metering pump 506, and the metering pump 506 is used to pump the water into the first delivery pipeline 501 and the second delivery pipeline 502, so as to irrigate the first irrigation area 201 and the second irrigation area 400.

[0059] In addition, the photovoltaic irrigation system in the embodiment of the present application also includes a flow control component 504, a soil environment detection room and a control module, wherein the flow control component 504 is arranged in at least one of the first delivery pipeline 501 and the second delivery pipeline 502; the soil environment detection component 505 is arranged in at least one of the first irrigation area 201 and the second irrigation area 400; the control module is respectively communicated with the flow control component 504 and the soil environment detection component 505; the control module is configured to control the flow control component 504 according to the detection data of the soil environment detection component 505 to adjust the irrigation flow of at least one of the first delivery pipeline 501 and the second delivery pipeline 502.

[0060] In the above embodiment, illustratively, flow control components 504 are provided on the first delivery pipeline 501 and the second delivery pipeline 502. The flow control component 504 can adopt a solenoid valve with controllable valve opening. The larger the opening of the solenoid valve, the greater the volume flow rate of water passing through. The first irrigation area 201 and the second irrigation area 400 are both provided with soil environment detection components 505. The soil environment detection component 505 can adopt a soil thermometer and humidity meter to detect the temperature and humidity conditions of the soil. The control module can adopt a programmable controller in related technologies, for example, a PLC (Programmable Logic Controller) microcontroller and other related modules.

[0061] In some embodiments, a humidity warning threshold is set for the first irrigation area 201 and the second irrigation area 400, respectively. When the soil humidity detected by the soil environment detection element 505 is lower than the humidity warning threshold, it proves that the soil is lacking water, and the control module controls the flow control element 504 to start the irrigation operation. Here, the humidity warning threshold can be flexibly set according to factors such as the region, ambient temperature and humidity, and is not absolutely limited in the embodiments of the present application.

[0062] It should be noted that due to the different plant species in the first irrigation area 201 and the second irrigation area 400, the temperature and humidity control of the first irrigation area 201 and the second irrigation area 400 will also change accordingly. According to the irrigation needs, the control module switches the sprinkler head 503 or the drip irrigation nozzle to perform corresponding irrigation operations. For example, during the irrigation process, the first irrigation area 201 is sprinkler irrigation, and the second irrigation area 400 is drip irrigation, or the first irrigation area 201 and the second irrigation area 400 are both sprinkler irrigation, and the irrigation water volume and irrigation intensity are controlled according to the detection data of the soil environment detection component 505.

[0063] An exemplary working process of the photovoltaic irrigation system in the embodiment of the present application is as follows:

[0064] During operation, rainwater and snow water falling on the photovoltaic panel 100 and clean water for washing the photovoltaic panel 100 drip into the first irrigation area 201 along the outlet weir plate 101. The water purification plants in the first irrigation area 201 form plant retention. Part of the water is absorbed by the water purification plants, and part of it penetrates into the water filtration unit 203 by gravity. The water passing through the water filtration unit 203 is collected and enters the water storage unit 300 through the connecting pipe 301.

[0065] The soil environment detection element 505 of the first irrigation area 201 and the second irrigation area 400 detects the soil state. When it is detected that the soil moisture in the first irrigation area 201 is low, the control module controls the flow control element 504 of the first delivery pipeline 501 to open, and water passes through the first delivery pipeline 501 to irrigate the plants in the first irrigation area 201; when it is detected that the soil moisture in the second irrigation area 400 is low, the control module controls the flow control element 504 of the second delivery pipeline 502 to open, and water passes through the second delivery pipeline 502 to irrigate the plants in the second irrigation area 400.
