Description

Technical Field

[0001] This invention relates to the fields of photovoltaic power generation and ecological restoration technology, and more specifically, to a photovoltaic irrigation system. Background Technology

[0002] Currently, photovoltaic power stations are often built in the goaf areas of coal mines to make full use of the land, and shrubs and grasses are planted at these stations to supply livestock, thus developing the ecological value of the photovoltaic power stations. However, because coal mining and the construction of photovoltaic power stations damage the geology, the geological conditions in the goaf areas of coal mines often suffer from soil degradation such as sandification, resulting in a poor environment for vegetation growth.

[0003] To ensure the normal growth of vegetation, irrigation is carried out in photovoltaic areas. Current ecological irrigation in these areas still employs large-scale agricultural irrigation methods. Because photovoltaic power stations are typically built in areas with strong sunlight, soil evaporation is high, and the land has poor water retention, resulting in ineffective irrigation. To compensate for the large amount of water lost through evaporation caused by strong sunlight, existing technologies usually use more water for irrigation. However, increasing the amount of irrigation water, both during flow and after evaporation, often leads to uneven ground subsidence, causing photovoltaic panels and other facilities to overturn. This not only affects production safety but also wastes a significant amount of water resources, contradicting the original intention of developing ecological value. Summary of the Invention

[0006] Furthermore, multiple photovoltaic power generation devices are installed, and these multiple photovoltaic power generation devices are spaced apart along a first direction. The multiple photovoltaic power generation devices extending along the first direction form a photovoltaic power generation group. Multiple photovoltaic power generation groups are installed, and these multiple photovoltaic power generation groups are spaced apart along a second direction.

[0007] Furthermore, one side of the photovoltaic panel is hinged to the support frame, and a driving device is also provided between the photovoltaic panel and the support frame. The driving device is used to drive the photovoltaic panel to rotate relative to the side of the photovoltaic panel that is hinged to the support frame.

[0008] Furthermore, a guide rail is provided on the photovoltaic panel, and the driving device includes: a connecting plate, a slider on one side of the connecting plate, the slider being hinged to the connecting plate and slidingly engaged with the guide rail; a liquid storage cylinder and a piston rod, the liquid storage cylinder being mounted on a support frame, the piston rod having a piston end and a connecting end, the piston end being movably mounted inside the liquid storage cylinder, the connecting end being drivenly connected to the connecting plate, and the liquid storage cylinder having a connecting port that is connected to a spray pipe.

[0009] Furthermore, the drive device also includes a buffer cylinder, which is mounted on a support frame and connected to a communication port. The buffer cylinder also has an inlet and a outlet. The inlet is connected to a spray pipe, and a first shut-off valve is provided between the inlet and the spray pipe. A second spray head is provided at the outlet, and a second shut-off valve is provided between the outlet and the second spray head.

[0010] Furthermore, the photovoltaic panel includes a base plate and a body, with the body positioned above the base plate. The photovoltaic irrigation system also includes a cooling device, which includes: a cooling pipe positioned on the base plate, the cooling pipe having an inlet end and an outlet end positioned opposite each other, the outlet end being connected to a spray pipe; and a cooling assembly positioned between the water storage device and the inlet end, the cooling assembly being used to cool the water stored in the water storage device and to pass the cooled water into the cooling pipe.

[0011] Furthermore, the cooling assembly includes multiple sets of heat exchange tubes and a fan. The multiple sets of heat exchange tubes are arranged in parallel, with one end of the heat exchange tube connected to a water storage device and the other end connected to the inlet. The fan is arranged corresponding to the heat exchange tubes.

[0012] Furthermore, the water storage device has a water storage tank and a collection trough. The water storage tank has a water storage cavity, which is connected to the water supply system and the sprinkler pipe. The collection trough is located at the top of the water storage tank and is connected to the water storage cavity for collecting rainwater.

[0013] Furthermore, a temporary storage cylinder is provided inside the water storage cavity. The temporary storage cylinder is fixedly installed at the bottom of the collection tank. The temporary storage cylinder has a first opening and a second opening that are arranged opposite to each other. The first opening is connected to the collection tank. A sealing plate is provided at the second opening. The sealing plate is used to seal the second opening. An elastic element is provided between the sealing plate and the collection tank.

[0015] By applying the technical solution of this invention, the support frame can lift the photovoltaic panel, creating a shaded area below the panel. Since the photovoltaic panel is designed and constructed to face the optimal direction of sunlight, the shaded area below the panel will be in a long-term shaded state, and the sunlight in the shaded area will be less than that in other areas for a long time. This application solves this problem by installing sprinkler pipes through the support frame, allowing the sprinkler pipes to spray water into the shaded area for irrigation. The vegetation and soil growing in the shaded area have stronger water retention capacity, resulting in less water evaporation during and after irrigation, reducing uneven ground settlement, ensuring the stability of the photovoltaic power generation device, and allowing water to diffuse into the soil layer of the non-shaded area after entering the soil layer, reducing soil erosion, which is beneficial to vegetation growth. Through natural replacement, an ecological cumulative effect is formed, improving soil fertility, forming a virtuous cycle during irrigation, and ensuring irrigation effect.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a photovoltaic irrigation system, which includes a water storage device 100, a photovoltaic power generation device 200, and an irrigation device. The photovoltaic power generation device 200 has a photovoltaic panel 210 and a support frame 220. The photovoltaic panel 210 is fixedly mounted on the top of the support frame 220, and a shaded area is formed below the photovoltaic panel 210. The irrigation device has a spray pipe 310, which is connected to the water storage device 100 and passes through the support frame 220. Multiple first spray heads 311 are spaced apart along the extension direction of the spray pipe 310, and the area sprayed by the first spray heads 311 is within the shaded area.

[0034] By applying the technical solution of this invention, the support frame 220 can lift the photovoltaic panel 210, forming a shaded area below the photovoltaic panel 210. Since the photovoltaic panel 210 needs to be oriented towards the optimal light direction during design and construction, the shaded area below the photovoltaic panel 210 will be in a long-term shaded state, and the light in the shaded area will be less than that in other areas for a long time. This application sets a sprinkler pipe 310 through the support frame 220, so that the sprinkler pipe 310 sprays water into the shaded area for irrigation. The vegetation and soil growing in the shaded area have stronger water retention capacity, less water evaporation during and after irrigation, reducing uneven ground settlement, ensuring the stability of the photovoltaic power generation device 200, and the water can diffuse to the soil layer in the non-shaded area after entering the soil layer, reducing soil erosion, which is conducive to vegetation growth. Through natural replacement, an ecological cumulative effect is formed, improving soil fertility, forming a virtuous cycle during irrigation, and ensuring irrigation effect.

[0035] Specifically, multiple photovoltaic power generation devices 200 are installed, spaced apart along a first direction. Spray pipes 310 sequentially pass through these devices, forming a photovoltaic power generation array. Multiple photovoltaic power generation arrays are installed, spaced apart along a second direction to achieve the construction of a photovoltaic area. A first diversion pipe 102 and a first pump body 101 are also installed between the water storage device 100 and the spray pipes 310. The multiple spray pipes 310 are connected in parallel to the first diversion pipe 102. Water flowing out of the water storage device 100, under the action of the first pump body 101, first flows through the first diversion pipe 102 to the multiple spray pipes 310, thus achieving the spraying operation for the multiple photovoltaic power generation arrays.

[0036] Reference Figure 1 As shown, in this application, the x-direction is the first direction and the y-direction is the second direction.

[0037] Specifically, the sprinkler pipe 310 can extend through the photovoltaic power generation device 200 at its end in the first direction and extend to the slope area below the goaf. The side wall of the sprinkler pipe 310 extending to the slope area can also be equipped with a first sprinkler head 311 to irrigate the slope area indiscriminately.

[0038] Specifically, when the surface soil of the photovoltaic site has strong water retention and the area is covered with obvious grass, the irrigation area is 15cm inward from each boundary of the photovoltaic panel 210, and irrigation is carried out once every 7 days. The water supply should be sufficient to allow effective infiltration to a depth of 60cm below the surface.

[0039] In one embodiment of this application, one side of the photovoltaic panel 210 is hinged to the support frame 220, and a driving device is also provided between the photovoltaic panel 210 and the support frame 220, as shown in the reference. Figure 3 and Figure 4As shown, the driving device is used to drive the photovoltaic panel 210 to rotate relative to the side of the photovoltaic panel 210 that is hinged to the support frame 220. With the above configuration, the photovoltaic panel 210 can adapt to the angle of sunlight in different seasons by rotating relative to the support frame 220, thereby improving the sunlight reception effect, ensuring the power generation efficiency of the photovoltaic power generation device 200, and also adaptively ensuring the area of ​​the shading area to improve the soil and water conservation effect of the shading area.

[0040] Specifically, the photovoltaic panel 210 is equipped with a guide rail 230, and the driving device includes a connecting plate 410, a liquid storage cylinder 430, and a piston rod 440. A slider 420 is provided on one side of the connecting plate 410, hinged to the connecting plate 410 and slidably engaged with the guide rail 230. The liquid storage cylinder 430 is mounted on a support frame 220. The piston rod 440 has a piston end and a connecting end. The piston end is movably mounted within the liquid storage cylinder 430, and the connecting end is drivenly connected to the connecting plate 410. The liquid storage cylinder 430 has a connecting port 431, which communicates with the spray pipe 310. Through this arrangement, water from the spray pipe 310 can enter the liquid storage cylinder 430, and the piston rod 440 can move upwards under water pressure to rotate the photovoltaic panel 210 and adjust its angle. The guide rail 230 guides the movement of the slider 420, ensuring smooth operation between the driving device and the photovoltaic panel 210.

[0041] Furthermore, the drive device also includes a buffer cylinder 450, which is mounted on the support frame 220 and connected to the communication port 431. The buffer cylinder 450 also has a liquid inlet and a liquid outlet. The liquid inlet is connected to the spray pipe 310. A first shut-off valve 451 is provided between the liquid inlet and the spray pipe 310. A second spray head 453 is provided at the liquid outlet. A second shut-off valve 452 is provided between the liquid outlet and the second spray head 453. Through the above settings, the angle of the photovoltaic panel 210 can be adaptively adjusted according to the vegetation growth and climate change monitoring in the shaded area. Specifically, when the photovoltaic panel 210 needs to rotate upward, the controller can open the first shut-off valve 451, and the water in the spray pipe 310 enters the buffer tank 450 under water pressure. After the buffer tank 450 is full, the water enters the storage tank 430, causing the piston rod 440 to move upward. The buffer tank 450 can prevent the water pressure from directly impacting the piston rod 440, ensuring the stability of the cooperation between the storage tank 430 and the piston rod 440. After the photovoltaic panel 210 is raised, the first shut-off valve 451 can be closed to keep the photovoltaic panel 210 at a certain angle. When the photovoltaic panel 210 needs to rotate downward, the second shut-off valve 452 can be opened, allowing the water in the buffer tank 450 to be sprayed onto the shaded area through the second spray head 453. The water pressure in the storage tank 430 decreases, and the photovoltaic panel 210 can rotate downward under its own weight, thus achieving angle adjustment.

[0042] In this application, a buffer structure is also provided between the connecting plate 410 and the support frame 220 to buffer the downward rotation of the photovoltaic panel 210, and to prevent the photovoltaic panel 210 from falling too fast and causing excessive vibration, which would affect the stability of the connection between the photovoltaic panel 210 and the support frame 220.

[0043] Specifically, the buffer structure includes a first guide rod 460 and a first spring 470. The first spring 470 is sleeved on the first guide rod 460. The first guide rod 460 is fixedly connected to the connecting plate 410 and extends vertically. A first limiting plate 480 is also provided on the support frame 220. The first limiting plate 480 is mounted on the support frame 220 through a mechanism supporting the upright plate. The first guide rod 460 passes through the first limiting plate 480. One end of the first spring 470 is fixedly connected to the first limiting plate 480, and the other end is fixedly connected to the abutting end of the first guide rod 460. The first spring 470 provides an elastic force for the first guide rod 460 and the connecting plate 410 to move upward, thereby buffering the downward movement of the photovoltaic panel 210. Furthermore, the first guide rod 460 also guides the movement of the first guide rod 460 and the connecting plate 410.

[0044] Furthermore, multiple buffer structures can be configured, such as two, three, or four.

[0045] In some feasible embodiments of this application, a filter screen 454 may be provided in the buffer tank 450 to filter the water entering the storage tank 430, so as to prevent impurities from affecting the cooperation effect and service life of the storage tank 430 and the piston rod 440.

[0046] Specifically, in this application, see reference to Figures 1 to 5 As shown, the photovoltaic panel 210 includes a base plate 211 and a main body, with the main body positioned above the base plate 211. The photovoltaic irrigation system also includes a cooling device, which comprises a cooling pipe 510 and a cooling assembly 520. The cooling pipe 510 is mounted on the base plate 211 and has an inlet end and an outlet end positioned opposite each other. The outlet end is connected to the spray pipe 310. The cooling assembly 520 is positioned between the water storage device 100 and the inlet end. The cooling assembly 520 is used to cool the water stored in the water storage device 100 and to pass the cooled water into the cooling pipe 510. During the use of the photovoltaic panel 210, overheating may occur, requiring cooling of the photovoltaic panel 210 to improve its power generation efficiency and extend its service life. This application utilizes the water stored in the water storage device 100 within the irrigation system, allowing the cooled water to flow through the photovoltaic panel 210 for heat exchange, thereby reducing the instability between the main body and the base plate of the photovoltaic panel 210 and effectively lowering the temperature of the photovoltaic panel 210.

[0047] like Figure 6 and Figure 7As shown, the cooling assembly 520 includes multiple sets of heat exchange tubes 521 and a fan 522. The multiple sets of heat exchange tubes 521 are arranged in parallel, specifically 3, 4, or 5, etc. One end of each heat exchange tube 521 is connected to the water storage device 100, and the other end is connected to the inlet. The fan 522 is arranged corresponding to the heat exchange tubes 521. Through the above arrangement, the fan 522 can reduce the temperature of the water inside the heat exchange tubes 521, thereby cooling the stored water.

[0048] In the embodiments provided in this application, each photovoltaic power generation unit is provided with a cooling water inlet pipe 540 and a cooling water outlet pipe 550. The inlet end of each cooling pipe 510 is connected to the cooling water inlet pipe 540 via a hose, and the outlet end of each cooling pipe 510 is connected to the cooling water outlet pipe 550 via a hose. Multiple cooling pipes 510 are arranged in parallel between the cooling water inlet pipe 540 and the cooling water outlet pipe 550. Multiple cooling water inlet pipes 540 are connected to the cooling components via a second branch pipe 530, and multiple cooling water outlet pipes 550 are connected in parallel with the first branch pipe 102 to allow the cooled water after heat exchange to be introduced into the spray pipe 310 for irrigation. Specifically, a one-way valve is provided on both the cooling water inlet pipe 540 and the cooling water outlet pipe 550 to control the flow direction of the cooling water and prevent the cooling water from flowing back into the water storage device 100.

[0049] Specifically, a second pump body can be installed on the second branch pipe 530 to drive the flow of cold water.

[0050] Furthermore, the water storage device 100 includes a water storage tank 110 and a collection trough 120. The water storage tank 110 has a water storage cavity, which is connected to the water supply system and the sprinkler pipe 310. The collection trough 120 is located at the top of the water storage tank 110 and is connected to the water storage cavity for collecting rainwater. With the above configuration, the water storage tank 110 can be connected to the municipal water supply system or the irrigation water supply system for storing irrigation water. In addition, it can also collect rainwater through the collection trough 120 for irrigation, making full use of water resources.

[0051] Specifically, the collection trough 120 can be a conical trough to facilitate the collection and diversion of rainwater, so that the rainwater in the collection trough 120 can enter the water storage tank 110.

[0052] like Figure 8As shown, a temporary storage cylinder 130 is installed inside the water storage chamber. The temporary storage cylinder 130 is fixedly installed at the bottom of the collection tank 120. The temporary storage cylinder 130 has a first opening and a second opening that are arranged opposite to each other. The first opening communicates with the collection tank 120, and a sealing plate 131 is installed at the second opening to seal it. An elastic element is installed between the sealing plate 131 and the collection tank 120 to provide an elastic force for the sealing plate 131 to move toward the second opening. With the above arrangement, when the pressure provided by the rainwater collected in the temporary storage cylinder 130 on the sealing plate 131 can overcome the elastic force of the elastic element, the sealing plate 131 can open, and rainwater can enter the water storage chamber through the second opening. After the water in the temporary storage cylinder 130 flows out, the sealing plate 131 will continue to seal the second opening under the elastic force of the elastic element, so as to reduce the evaporation of water in the water storage tank 110 and prevent water waste.

[0053] In this application, the elastic element includes a second guide rod 132, a second spring 133, and a second limiting plate 134. The second limiting plate 134 is fixedly disposed at the first opening. The second guide rod 132 is fixedly connected to the second limiting plate 134 and passes through the second limiting plate 134. A limiting block is provided at one end of the second guide rod 132 away from the sealing plate 131. The second spring 133 is disposed between the limiting block and the second limiting plate 134 and is used to provide an elastic force to the sealing plate 131 in the direction of the second opening to drive the sealing plate 131.

[0054] To further improve vegetation growth, photovoltaic irrigation systems also include water and fertilizer mixing devices, such as... Figure 8 As shown, the water-fertilizer mixing device includes a mixing tank 610 and a mixing element 620. The mixing tank 610 has an inlet and a outlet arranged opposite to each other. The inlet is connected to a water storage device 100. A third pump body 630 is provided between the mixing tank 610 and the water storage device 100 to introduce water stored in the water storage device 100 into the mixing tank 610. The outlet is connected to a manifold 640, which is connected to a first branch pipe 102 so that the mixing tank is connected to multiple spray pipes 310. The mixing tank 610 is also provided with a feeding port 611 for adding fertilizer into the mixing tank 610. The mixing element 620 is provided inside the mixing tank 610 to mix water and fertilizer. The mixed water-fertilizer mixture can enter the spray pipes 310 through the manifold 640 to fertilize the vegetation during spray irrigation, improve the vegetation growth effect, and improve the convenience of fertilization. Specifically, a one-way valve may be installed on the manifold 640, and the manifold 640 is connected to the upstream of the first pump body 101 to ensure the correct flow of water.

[0055] When the surface soil of the photovoltaic site has poor water retention and there is no obvious grass cover on the surface of the area, the irrigation area is 20cm inward from each boundary of the photovoltaic panel 210, and irrigation is carried out once every 3 days. The water supply should be sufficient to allow effective infiltration to 150cm below the surface, and water and fertilizer should be integrated for irrigation.

[0056] By applying the technical solution of this application, targeted irrigation of the shaded area can effectively reduce the evaporation of surface water compared to the indiscriminate irrigation in traditional technical solutions, ensuring irrigation effect. It can also reduce the impact of land subsidence, thereby improving the stability of photovoltaic panel 210 installation, realizing the integration and complementarity of photovoltaic safety production and vegetation enhancement, reducing soil erosion caused by agricultural irrigation, increasing regional vegetation coverage, enriching regional vegetation diversity, improving surface habitat, effectively increasing soil moisture content, thereby increasing vegetation coverage, and forming an ecological cumulative effect through natural succession, thus improving soil fertility.
