[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-9 as shown, the present invention provides a technical solution:

[0031] An integrated system for increasing snow storage and water conservation and ecological restoration of photovoltaic panels in alpine degraded grasslands includes a water storage tank 1. A photovoltaic module 3 is provided on the top of the water storage tank 1, and an irrigation assembly 2 is provided at the bottom of the water storage tank 1. The photovoltaic module 3 includes a snow storage board 33. The snow storage board 33 is inclined. A plurality of photovoltaic panels 34 are provided on the top of the snow storage board 33. The inside of the snow storage board 33 is a cavity structure. An electric heating wire 331 is provided inside the snow storage board 33. After the electric heating wire 331 is energized and heated, the snow attached to the surface of the photovoltaic panel 34 can be melted. A drainage groove 35 is provided between two adjacent photovoltaic panels 34. The drainage groove 35 is arranged along the width direction of the snow storage board 33. The melted snow can flow down along the drainage groove 35. A snow baffle 4 is fixedly connected to the peripheral surface of the snow storage board 33. The periphery of the snow baffle 4 is a convex structure for preventing the melted snow from overflowing. The photovoltaic module 3 further includes a diagonal brace 31 installed on the top surface of the water storage tank 1. The snow storage board 33 is installed on the inclined top surface of the diagonal brace 31. A crossbeam frame 32 is installed at a position near the bottom inside the diagonal brace 31.

[0032] Specifically, an ecological restoration area is delimited around the water storage tank 1, grass seeds and ground cover plants are sown, an irrigation pipe network is laid, the irrigation assembly 2 is connected to the water storage tank 1 and an intelligent control system, and a humidity sensor is installed on the grassland to transmit the monitoring data to the control center for system joint debugging.

[0033] Furthermore, the surface of the photovoltaic panel 34 has protrusions and grooves, which can enhance the adsorption force of snowflakes and allow more snow to adhere. At the same time, a snow baffle 4 is provided around the photovoltaic panel 34 to prevent snow from sliding outwards and increase the snow accumulation. A snow storage plate 33 is provided at the bottom of the photovoltaic panel 34. Using the waste heat generated by photovoltaic power generation, it is transferred to the snow storage plate 33 and the photovoltaic panel 34 through the built-in heating wire 331, so that the accumulated snow slowly melts, and the melted snow water flows into the connection shell 6 through the diversion groove 35.

[0034] Furthermore, the water storage tank 1 adopts a double-layer heat preservation structure. The inner layer is made of stainless steel, and the outer layer is made of polyurethane heat preservation material, with good heat preservation and anti-seepage performance.

[0035] In this embodiment, a filter tank 5 is installed on the cross beam frame 32. The interior of the filter tank 5 is a cavity structure. A filter element 51 is provided inside the filter tank 5, and a water pipe 52 communicating with the inner cavity of the water storage tank 1 is installed at a position near the rear side of the bottom of the filter tank 5.

[0036] Specifically, the filter element 51 inside the filter tank 5 can purify the melted snow. The filter element 51 can intercept impurities such as sediment and microorganisms carried in the snow water and play a filtering role. The snow water filtered by the filter element 51 becomes relatively clean water and flows into the water storage tank 1 through the water pipe 52. In this way, the impurities of the water entering the water storage tank 1 are reduced, which can effectively avoid blocking the pipelines of the irrigation assembly 2 and ensure that the subsequent irrigation system can operate stably and efficiently, providing clean water for the grassland ecological restoration.

[0037] In this embodiment, a connection shell 6 is provided on the front side of the filter tank 5. The interior of the connection shell 6 is a cavity structure. The connection shell 6 is communicated with its interior through the bottom surface of the snow baffle 4. The melted snow can flow along the inner cavity of the connection shell 6 to the inside of the filter tank 5. A grid plate 61 is provided at the water inlet of the connection shell 6 for intercepting large impurities in the snow accumulation.

[0038] Specifically, the grid plate 61 at the water inlet of the connection shell 6 can intercept large impurities such as branches and large ice blocks, and preliminarily filter the snow water. The snow water after preliminary filtration will flow into the filter tank 5 under the guidance of the connection shell 6, which can prevent large impurities from entering the filter tank 5, avoid subsequent blockage of the filter element 51, ensure that the filter tank 5 can normally play its fine filtering function, and ensure the stable and efficient progress of the melted snow water purification process.

[0039] In this embodiment, a fertilizer storage barrel 7 is also installed on the top surface of the water storage tank 1. A fertilizer delivery pump 72 is installed outside the fertilizer storage barrel 7. The water inlet of the fertilizer delivery pump 72 is communicated with the inner cavity of the fertilizer storage barrel 7. A connecting pipe 71 communicating with the inner cavity of the water storage tank 1 is installed at the water outlet of the fertilizer delivery pump 72. A fertilizer adding port 73 is provided at the top of the fertilizer storage barrel 7.

[0040] Specifically, when it is necessary to irrigate and fertilize the grassland, the fertilizer pump 72 is started. The fertilizer pump 72 generates suction, sucks the fertilizer in the fertilizer storage tank 7 through the water inlet, and then transports it to the water storage tank 1 through the connecting pipe 71. After the fertilizer enters the water storage tank 1, it is mixed with the water in the water storage tank 1 to form a water-fertilizer mixture, which is then evenly irrigated onto the grassland through the irrigation component 2 to meet the nutrient requirements during the ecological restoration of the grassland. The fertilizer can be conveniently added into the tank by the fertilizer addition port 73.

[0041] In this embodiment, a liquid level gauge 11 is provided on the front side of the water storage tank 1, and a leg support 12 is fixedly installed at the bottom of the water storage tank 1.

[0042] Specifically, the liquid level gauge 11 can monitor the water level height in the water storage tank 1. The staff can intuitively understand the water volume in the tank through the liquid level gauge 11, which is convenient for timely replenishment when the water volume is insufficient, preventing the irrigation operation from being affected due to water shortage.

[0043] In this embodiment, a motor 8 is installed on the outer surface of one side of the water storage tank 1. The output shaft end of the motor 8 movably penetrates the outer wall of the water storage tank 1 and extends into the interior. A stirring shaft 81 is installed at the output shaft end of the motor 8. The stirring shaft 81 is arranged along the length direction of the water storage tank 1, and a plurality of stirring blades 82 are installed on the stirring shaft 81.

[0044] Specifically, after the motor 8 is started, it drives the stirring shaft 81 and the stirring blades 82 to rotate together. Under the action of the stirring blades 82, the water in the water storage tank 1 and the fertilizer transported from the fertilizer storage tank 7 are fully mixed to form a uniform water-fertilizer mixture. This uniform mixing ensures that the water and nutrients are evenly distributed at every place irrigated onto the grassland through the irrigation component 2, providing more stable and effective nourishment for the ecological restoration of the alpine degraded grassland and improving the grassland restoration effect.

[0045] In this embodiment, the irrigation component 2 includes an irrigation pump 21 installed at the rear side of the water storage tank 1. The water inlet of the irrigation pump 21 is communicated with the inner cavity of the water storage tank 1. A water outlet pipe 22 is installed at the water outlet of the irrigation pump 21. A flow meter 23 is installed on the water outlet pipe 22. The end of the water outlet pipe 22 is communicated with a main pipeline 24. A plurality of branch pipelines 25 are equidistantly communicated on the main pipeline 24. The branch pipelines 25 are vertically arranged. A capillary pipe 26 is fixedly communicated at the bottom end of the branch pipeline 25. The capillary pipe 26 is laid on the grassland, and a plurality of irrigation holes 27 are provided on the surface of the capillary pipe 26.

[0046] Specifically, when starting the irrigation operation, the irrigation pump 21 starts to work, sucking the mixed water and fertilizer in the storage tank 1 from its water inlet. Subsequently, the water and fertilizer are output through the water outlet pipe 22 connected to the water outlet of the irrigation pump 21. The flowmeter 23 can monitor and display the flow rate of the flowing water and fertilizer in real time, facilitating the staff to accurately regulate the irrigation amount according to the actual needs of the grassland. The water and fertilizer are preliminarily distributed into the branch pipes 25 through the main pipe 24, and the branch pipes 25 further evenly disperse the water and fertilizer onto the capillary pipes 26. Finally, the water and fertilizer slowly and evenly penetrate into the grassland soil through the irrigation holes 27 on the capillary pipes 26, realizing the irrigation of the alpine degraded grassland and promoting the growth of grassland vegetation and ecological restoration.

[0047] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0048] Working principle: When it snows in winter, the snowflakes fall on the photovoltaic panel 34. When snow melting is required, the heating wire 331 in the snow storage plate 33 is electrified to melt the snow attached to the surface of the photovoltaic panel 34. The melted snow flows down along the diversion trough 35. After intercepting large impurities through the grid plate 61 at the water inlet, it flows into the filter tank 5 through the connecting shell 6. In the filter tank 5, it is further filtered through the filter element 51, and then flows into the storage tank 1 through the water outlet pipe 52 at the rear side of the bottom, realizing the effective utilization of natural snowfall resources. The fertilizer storage barrel 7 adds fertilizer into the storage tank 1 through the fertilizer delivery pump 72 and the connecting pipe 71, and is stirred by the motor 8 driving the stirring shaft 81 and the stirring blades 82 to fully mix the water and fertilizer. When ecological restoration irrigation of the degraded grassland is required, the irrigation pump 21 conveys the mixed water and fertilizer in the storage tank 1 through the water outlet pipe 22. After measuring the flow rate by the flowmeter 23, it is transported to the main pipe 24, then through the branch pipes 25, and finally, through multiple irrigation holes 27 on the capillary pipes 26, the water and fertilizer are evenly irrigated onto the grassland, realizing the ecological restoration of the alpine degraded grassland.
