[0002] In the sand control technology of photovoltaic sand fields, the method of planting drought-resistant plants is usually adopted to improve the environment and promote vegetation recovery. Irrigation is a key link in supporting plant growth. There are currently two main irrigation methods: one is to directly spray through irrigation water sources to meet the water needs of plants; the other is to use a guide device to concentrate rainwater to the roots of plants.

[0003] However, direct spray irrigation often involves covering a large area with water, which may lead to a large consumption of water resources and high costs. At the same time, this method is difficult to accurately supply water to each plant, which may cause water waste.

[0004] On the other hand, although the practice of using guiding devices to collect and guide rainwater can reduce dependence on water resources, due to the scarcity and uneven distribution of rainwater in desert areas, the irrigation effect of this method is limited, and its contribution to improving plant survival rates is also limited.

[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In the process of managing photovoltaic sand fields, the strategy of planting drought-resistant plants is usually adopted to improve the environment. In order to improve the survival rate of plants, irrigation usually adopts two methods: one is to spray irrigation water directly on the plants, and the other is to install a water guide device to guide rainwater to the plants. However, due to its wide coverage, spray irrigation may lead to waste of water resources and increased costs. The method of relying on water guide devices to collect rainwater has limited irrigation effect and effect on improving plant survival rate.

[0037] Through in-depth research, the inventors found that the core problem of the low survival rate of plants in the photovoltaic sand field area is that the pore water level in this area is far from the ground surface, which makes it difficult for plant roots to obtain water in the waterless layer and must rely on external irrigation. Only when the roots extend to the pore water level can plants survive by absorbing water through the roots. Therefore, the key is to ensure that the plant roots can successfully reach and expand to the pore water level area.

[0038] In view of this, the present application provides a photovoltaic sand control device to ensure that plants can successfully survive the water shortage period after planting until the root system can extend to the pore water level to improve the survival rate of the plants.

[0039] The photovoltaic sand control device provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0040] Figure 1 A schematic diagram of the structure of a photovoltaic sand control device provided in an embodiment of the present application.

[0041] like Figure 1 As shown, the photovoltaic sand control device of this embodiment includes: an irrigation device 100 and a flow regulating device 200.

[0042] The irrigation device 100 includes a water tank 110 and a water pipe 120 connected to the water tank 110. The water pipe 120 extends toward the root system of the plant 700 and is a flexible pipe.

[0043] The flow regulating device 200 is arranged below the surface 500 of the planting area, and the flow regulating device 200 includes a driving structure 210. The driving end 211 of the driving structure 210 has an extrusion position close to the water pipe 120 and a conduction position away from the water pipe 120. The driving end 211 moves between the extrusion position and the conduction position to adjust the flow rate of the water pipe 120.

[0044] Applying the technical solution of this embodiment, the photovoltaic sand control device includes an irrigation device 100 and a flow regulating device 200. The irrigation device 100 includes a water tank 110, which is used to store irrigation water for watering plants. The water tank 110 guides the irrigation water to the plants through the water pipe 120, thereby irrigating the plants. The flow regulating device 200 can adjust the irrigation water flow of the irrigation device 100, thereby achieving precise irrigation of the plants, so that the irrigation water can support the root system of the plant to grow to the pore water level as much as possible, so that the operator does not need to frequently fill the irrigation water in the water tank 110.

[0045] Specifically, the flow regulating device 200 includes a driving structure 210, and a driving end 211 of the driving structure 210 has a squeezing position close to the water pipe 120 and a conducting position away from the water pipe 120, and the driving end 211 moves between the squeezing position and the conducting position. Since the water pipe 120 is a flexible pipe, when the driving end 211 moves from the conducting position to the squeezing position, the water pipe 120 is squeezed, and its flow volume gradually decreases until it is closed. When the driving end 211 moves from the squeezing position to the conducting position, the water pipe 120 gradually opens, and the flow volume gradually increases until it returns to the state of the maximum flow volume, thereby realizing the regulation of the flow volume of the water pipe 120.

[0046] It should be noted that, in order to reduce the loss of irrigation water in the irrigation device 100, the irrigation device can be set below the ground surface 500 of the planting area, thereby reducing the evaporation of irrigation water in the water storage tank 110 due to the high ground surface temperature. Accordingly, the flow regulating device 200 can be set below the ground surface 500 of the planting area, so that the flow regulating device 200 can adjust the flow rate of the water pipe 120.

[0047] It should also be noted that the water pipe 120 is a flexible pipe, and the location of the flexible pipe is flexible, so that the flexible pipe can be pulled to the root system of the plant. At the same time, the flexible pipe is easy to deform, so that the driving end of the driving device can adjust the flow rate of the water pipe 120 by moving, rotating, etc.

[0048] In some embodiments, the photovoltaic sand control device further includes a photovoltaic power generation device 300 , which is disposed above the ground surface 500 of the planting area. The photovoltaic power generation device 300 is connected to the flow regulating device 200 to supply power to the flow regulating device 200 .

[0049] In the above structure, a photovoltaic power generation device 300 can be set in the photovoltaic sand field, and the flow regulating device 200 is powered by the electric energy generated by the photovoltaic power generation device 300, which efficiently utilizes the light energy resources of the photovoltaic sand field to power the flow regulating device 200, thereby achieving energy saving.

[0050] Figure 3 A schematic diagram of a flow regulating device for a photovoltaic sand control device provided in an embodiment of the present application;

[0051] like Figure 3 As shown, in some embodiments, the flow regulating device 200 further includes an energy storage device 220 , the photovoltaic power generation device 300 is connected to the energy storage device 220 , and the energy storage device 220 is connected to the driving structure 210 .

[0052] In the above structure, the energy storage device 220 can further improve the operational stability of the flow regulating device 200, compensating for the unstable power generation capacity of the photovoltaic power generation device 300, thereby enabling the flow regulating device 200 to accurately regulate the flow of irrigation water.

[0053] Exemplarily, the energy storage device 220 may be a power source capable of realizing charging and discharging functions.

[0054] It should also be noted that, in some embodiments, the photovoltaic sand control device further includes an inverter connected between the photovoltaic power generation device 300 and the energy storage device 220 .

[0055] In some embodiments, the photovoltaic sand control device further includes a controller 240 , which can send a control signal to the driving structure 210 . In response to the control signal, the driving structure 210 can generate corresponding movement at the driving end 211 , thereby adjusting the flow rate of the water pipe 120 .

[0056] Figure 2 A schematic structural diagram of a flow regulating device for a photovoltaic sand control device provided in an embodiment of the present application.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the flow regulating device 200 includes a shell 230, the driving structure 210 is disposed in the shell 230, the water pipe 120 passes through the shell 230 and is located between the driving structure and the shell 230, and when the driving end 211 moves from the conduction position to the extrusion position, the driving end 211 abuts the flexible tube against the inner wall of the shell 230.

[0058] In the above structure, the flow regulating device 200 can be set below the ground surface 500, and the housing 230 can accommodate the driving structure 210, the energy storage device 220 and the controller 240, isolating the above structure from the soil layer to achieve a protective effect. At the same time, the housing 230 has a large strength and can cooperate with the driving end to form an extrusion effect on the water pipe 120. Specifically, when the driving end 211 moves from the conduction position to the extrusion position, the driving end 211 abuts the flexible tube against the inner wall of the housing 230 to achieve the regulation of the flow rate of the water pipe 120.

[0059] like Figure 2 As shown, in some embodiments, the driving structure 210 includes a rotary motor and a cam disposed on a rotating shaft of the rotary motor, and the cam forms a driving end 211 of the driving structure 210 .

[0060] Specifically, the cam has a first end and a second end relative to each other, the distance from the first end of the cam to the rotating shaft is smaller than the distance from the second end of the cam to the rotating shaft, when the driving end 211 is in the extrusion position, the first end of the cam abuts and cooperates with the water pipe 120, and when the driving end 211 is in the conduction position, the second end of the cam contacts and cooperates with the water pipe 120.

[0061] In some embodiments, the drive structure may further include a linear motor, and a drive shaft of the linear motor forms a drive end of the drive structure. The drive shaft can move between a squeeze position and a conduction position, thereby achieving a regulation effect on the flow rate of the water pipe 120.

[0062] Furthermore, if Figure 1 As shown, in some embodiments, the photovoltaic sand control device also includes: a water retaining device 400, the water retaining device 400 includes a first water retaining portion 410 and a second water retaining portion 420, and there is a planting space for planting plants 700 between the first water retaining portion 410 and the water retaining portion, and the irrigation device 100 is arranged in the planting space.

[0063] In the above structure, the water retaining device 400 can stop the irrigation water flowing out of the irrigation device 100 to prevent the irrigation water from diffusing to the area far away from the plant root system, thereby increasing the water content in the soil at the plant root system, improving the utilization rate of the irrigation water, and further improving the survival rate of the plant. Specifically, the water retaining device 400 includes a first water retaining portion 410 and a second water retaining portion 420, and a planting space for planting plants 700 is formed between the first water retaining portion 410 and the second water retaining portion 420. The first water retaining portion 410 and the second water retaining portion 420 can block the irrigation water flowing out of the irrigation device 100 from flowing to a position outside the planting space, guide the irrigation water to diffuse downward, and help guide the irrigation water to the pore water level 600, and further help to construct a channel connecting the pore water level 600 and the irrigation water in the planting space, thereby effectively improving the irrigation effect of the plant.

[0064] In some embodiments, the first water retaining portion 410 and the second water retaining portion 420 are buried in the planting area of ​​the plant 700, and the top ends of the first water retaining portion 410 and the second water retaining portion 420 extend to the ground surface 500 of the planting area, and the bottom ends extend to the pore water level 600 of the planting area.

[0065] In the above structure, since the top ends of the first water retaining portion 410 and the second water retaining portion 420 both extend to the surface of the planting area, and the bottom ends both extend to the pore water level 600 of the planting area, the first water retaining portion 410 and the second water retaining portion 420 can not only block the irrigation water flowing out of the irrigation device 100 from flowing to a position outside the planting space, thereby improving the utilization rate of the irrigation water, but also the first water retaining portion 410 and the second water retaining portion 420 can also guide the irrigation water to diffuse downward, which helps to guide the irrigation water to the pore water level, and then helps to build a channel in the planting space that connects the pore water level with the irrigation water, thereby effectively improving the irrigation effect of the plant.

[0066] It should be noted that the pore water level refers to the height of the water level in the pores of underground rocks or soil. The change of the pore water level is affected by many factors, including rainfall, groundwater recharge, groundwater discharge, etc. The measurement of the pore water level can be achieved by various water level gauges or pressure gauges. For example, the pore water level can be measured by a pore water pressure gauge or a vibrating wire water level gauge.

[0067] In some embodiments, the irrigation device 100 further includes an injection needle 130 disposed at the water outlet end of the water conduit 120 , and the injection needle 130 is used to be inserted into the root system of the plant 700 .

[0068] In the above structure, the plant root system is an important part of the plant's water absorption. Therefore, by connecting the injection needle 130 to the plant root system, irrigation water can be directly injected into the plant's root system, thereby improving the irrigation effect, achieving precise irrigation, and saving irrigation water.

[0069] It should be noted that the injection needle 130 can be passed through the cortex 711 of the plant root system and connected to the wood part 712 , so that the irrigation water can be directly injected into the wood part 712 .

[0070] It should also be noted that the injection needle 130 and the plant root system can be fixed by a fastener 800, and the fastener 800 can be a rubber band.
