Description

Technical Field

[0001] The present invention relates to an irrigation system, in particular to a photovoltaic panel intensive water use irrigation system for desert ecological management, belonging to the technical field of desert ecological management. Background Art

[0002] Due to their unique geographical location, arid climate, and frequent sandstorms, desertification in desert regions has become a serious threat to human survival and socio-economic development. Desertification not only causes ecosystem imbalance but also shrinks arable land. Therefore, effectively managing deserts and sandy areas and curbing their expansion are key components of current ecological development. Traditional management measures, such as enclosures and conservation, artificial afforestation, and sand-fixing nets, require large engineering efforts and high investment, but their effectiveness is limited. Afforestation or pasture planting can better manage the desert environment, but these methods require watering to ensure their continued growth. To further utilize desert terminal resources, solar photovoltaic panels will be installed in afforestation areas. This combination of photovoltaic panels and specialized pastures can mitigate wind and sand erosion, enrich the land, and reduce dust. It is beneficial to photovoltaic power generation and can improve the ecological environment. However, wind and sand will cause sand accumulation and dust in the photovoltaic area, reducing the power generation efficiency and polluting the environment. Therefore, in order to better achieve the photovoltaic power generation effect, the photovoltaic panels need to be cleaned regularly. The water used for cleaning the photovoltaic panels can be further utilized to irrigate trees or pastures.

[0003] The cleaning brush is moved by the rotating frame to move the cleaning brush toward the photovoltaic panel, and the cleaning brush is moved by the rotating frame to move the cleaning brush toward the photovoltaic panel, so as to clean the surface of the photovoltaic panel more efficiently. After that, some impurities will be stuck on the cleaning brush or sponge strip used. For example, for photovoltaic panels in a fan environment, since the surface of the photovoltaic panels is mainly accumulated sand, it is easy to adhere to the cleaning brush, which will cause scratches on the surface of the photovoltaic panels and incomplete cleaning after long-term use. That is, the existing cleaning method has many disadvantages, and the cleaning brush is easy to wear out, and long-term outdoor cleaning cannot be achieved. Secondly, there is no reasonable reuse of the clean water generated, and the photovoltaic panels will also collect a certain amount of rainwater on the upper surface when it rains. If the clean water and part of the rainwater can be collected and utilized, it can better save water resources. The photovoltaic panels are installed in open areas such as outdoors, so some plants will be planted in the installation area of ​​the photovoltaic panels. The existing technology only cleans the photovoltaic panels, and fails to combine the photovoltaic panels with the surrounding planting environment, and cannot play a role in improving the environment.

While generating electricity through the photovoltaic panel 1, it can also achieve the management of the surrounding environment, so that solar power generation and ecological management complement each other's shortcomings, and achieve multiple ecological benefits of land improvement, sand fixation, sand control, and vegetation restoration while generating electricity. It can also provide high-quality fodder, promote the development of animal husbandry, and improve economic and ecological benefits.

[0038] The fixed cleaning pipe 31 and the movable cleaning pipe 32 are distributed in a misaligned vertical state. The fixed cleaning pipe 31 is parallel to the inclined upper edge of the photovoltaic panel 1. The movable cleaning pipe 32 moves horizontally along the inclined upper edge of the photovoltaic panel 1, and the movable cleaning pipe 32 is parallel to the inclined plate body of the photovoltaic panel 1. Fixed cleaning nozzles 314 are provided on the pipe body of the fixed cleaning pipe 31, and movable cleaning nozzles 315 are provided on the pipe body of the movable cleaning pipe 32.

[0039] Embodiment 2

[0040] Based on Embodiment 1, the improvement is as follows:

A U-shaped drain groove 24 is provided on the plate body of the outer frame plate 2, and the drain groove 24 is located on both sides and the bottom edge of the photovoltaic panel 1. The drain groove 24 at the bottom edge of the photovoltaic panel 1 is connected to the recovery pipe 54, so that the photovoltaic panel 1 and the outer frame plate 2 can be combined together, and then the cleaning water or rainwater can flow downward along the inclined surface of the photovoltaic panel 1 to be collected by the drain groove 24. When the movable cleaning pipe 32 comprehensively flushes and cleans the photovoltaic panel 1, the cleaning water sprayed by the movable cleaning pipe 32 when it moves to both sides can also be collected by the drain groove 24 and can converge to the bottom edge of the drain groove 24 for recovery, realizing the maximum collection of the cleaning water or rainwater on the surface of the photovoltaic panel 1.

[0042] Furthermore, a side wall of the drainage trough 24 close to the side of the photovoltaic panel 1 is set as a water-guiding slope 25, and a filter screen 22 is placed on the drainage trough 24. The filter screen 22 can block the space inside the drainage trough 24, thereby preventing larger debris such as leaves or weeds from falling into the trough and affecting the normal drainage of the drainage trough 24. At the same time, since the water-guiding slope 25 is provided, when the filter screen 22 is placed on the opening at the upper end of the drainage trough 24, a certain gap will be left between the filter screen 22 and the water-guiding slope 25, thereby facilitating clean water or rainwater to flow into the trough along the gap.

[0043] like Figure 1 、 Figures 4 to 9 As shown, the cleaning assembly 3 also includes a U-shaped frame 33, a threaded rotating rod 34 and a slider 35.

The electromagnetic three-way valve 316 and the limit switch 36 are both connected to the external terminal for signal transmission. In the initial state, the fixed clean water supply pipe 311 can be opened at any time through the electromagnetic three-way valve 316. The fixed clean water supply pipe 311 or the movable clean water supply pipe 312 supplies water. If the fixed clean water supply pipe 311 is supplied with water first, when the water is transported into the fixed clean water supply pipe 311, it can drive the rotating water wheel in the forward turbine 38 to rotate forward, and then drive the threaded rotating rod 34 to rotate forward, so as to realize the movement of the slider 35 in one direction. When it moves to the end point, the slider 35 will touch the limit switch 36 of the end point. At this time, the electromagnetic three-way valve 316 will be controlled to switch the passage, and water will be supplied to the movable clean water supply pipe 312. Then the water is When transported to the movable cleaning pipe 32, it can drive the rotating water wheel in the reverse turbine 39 to reverse, and then drive the threaded rotating rod 34 to reverse, so as to drive the slider 35 to move in the other direction. While the movable cleaning pipe 32 moves, it can also spray the surface of the photovoltaic panel 1. When it moves to the end point, the slider 35 will touch the limit switch 36 of the end point, and the above process can be repeated. Through intermittent cleaning and flushing of the fixed cleaning pipe 31 and the movable cleaning pipe 32, it is ensured that the photovoltaic panel 1 is thoroughly cleaned.
