[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the desert area ecological photovoltaic power station 100 of the embodiment of the present invention includes a photovoltaic array, an ecological protection layer 2, a water collection system and an automatic irrigation system. The photovoltaic array is arranged on the ground in the desert area, and the photovoltaic array includes a plurality of photovoltaic panels 1, and the photovoltaic panels 1 are used to absorb solar energy and convert it into electrical energy. The ecological protection layer 2 is arranged on the ground below the photovoltaic panels 1, and is used to collect precipitation in the desert area and condensation water of the photovoltaic panels 1. The automatic irrigation system is connected to the water collection system to provide moisture for the ecological protection layer 2.

[0022] The desert area ecological photovoltaic power station 100 of the embodiment of the present invention makes efficient use of desert land resources when in use. By building photovoltaic power stations in desert areas, these lands that are not suitable for agriculture and other purposes can be effectively utilized, the occupation of high-quality land can be reduced, and the maximum utilization of land resources can be achieved. The ecological protection layer 2 is set on the ground below the photovoltaic panel 1 to prevent land degradation, maintain soil structure, and reduce soil erosion. The existence of the ecological protection layer 2 provides conditions for plant growth, helps to attract and maintain biodiversity, and reduces the negative impact of the photovoltaic power station on the local ecological environment. By collecting precipitation in the desert area and condensed water from the photovoltaic panel 1, water resources can be fully utilized to provide water for the ecological protection layer 2. The automatic irrigation system connected to the water collection system can intelligently adjust the water volume according to the needs of the ecological protection layer 2 to improve the utilization efficiency of water resources. The ecological protection layer 2 helps to reduce the impact of sand and dust on the photovoltaic panel 1 and improve the efficiency of photovoltaic power generation. The ecological protection layer 2 can also play a certain role in temperature regulation, reduce the temperature around the photovoltaic panel 1, and help improve the working efficiency of the photovoltaic panel 1. By reducing the impact on the ecological environment and extending the service life of the photovoltaic panel 1, the long-term operation of the photovoltaic power station can be guaranteed. Intelligent management of automatic irrigation systems helps reduce the daily maintenance costs of photovoltaic power plants.

[0023] In some embodiments, the ecological protection layer 2 is used to plant ecological vegetation 3.

[0024] The planting of ecological vegetation 3 helps to stabilize the soil, reduce wind erosion and water erosion, and improve the ecological environment in desert areas. Vegetation can absorb carbon dioxide in the atmosphere through photosynthesis, which helps to alleviate global climate change and improve the carbon fixation capacity of the surface. Planting ecological vegetation 3 with strong adaptability and drought resistance in desert areas helps to restore the natural vegetation in desert areas and promote the self-repair of the ecosystem. The planting of vegetation provides an environment for insects, birds and other organisms to live and reproduce, which helps to increase the biodiversity of desert areas. Through the planting of vegetation, the productivity of the land can be improved, and the desert area can be gradually transformed into land with certain production capacity. In the ecological vegetation 3, some plants with economic value can be selected for planting, such as medicinal materials, ornamental plants, etc., so as to bring additional economic benefits to the local area. The planting of vegetation can reduce the surface temperature, increase the air humidity, improve the regional microclimate, and provide a more stable climate environment for the operation of photovoltaic panels 1. The root system of vegetation can fix the soil and improve the water retention capacity of the soil, which is conducive to the recycling of water resources and the effectiveness of the water collection system. Planting ecological vegetation 3 helps to reduce the maintenance cost of the photovoltaic power station, because the vegetation can reduce the erosion of sand and dust on the photovoltaic panels 1 and reduce the cleaning frequency.

[0025] Optionally, the ecological planting is drought-tolerant shrubs or drought-tolerant herbaceous plants.

[0026] Drought-tolerant shrubs and herbs can adapt to the arid environment of desert areas and reduce their dependence on water resources, making them more suitable for growing in desert areas. Drought-tolerant plants usually have efficient water-use strategies and can grow under limited water resources, which helps to improve the water resource utilization efficiency of the entire power station. Drought-tolerant shrubs and herbs fix the soil with their developed root systems, effectively preventing soil erosion and enhancing the surface's resistance to wind erosion. Drought-tolerant plants grow quickly and can cover the surface quickly, increasing vegetation coverage and helping to improve the landscape of desert areas.

[0027] In some embodiments, the ecological protection layer 2 includes a surface covering layer 201, an organic fertilizer layer 202, a water retaining agent layer 203, a microbial inoculation layer 204, a clay layer 205 and an anti-corrosion layer 206 arranged in sequence from top to bottom.

[0028] like Figure 2As shown, the surface covering layer 201 can protect the structure of the lower layer from weathering and erosion, and prevent the upper soil and organic fertilizer from being lost due to rain erosion. The organic fertilizer layer 202 provides necessary nutrition for plants, promotes plant growth, and improves the fertility and water retention of the soil. The water retaining agent layer 203 can absorb and retain a large amount of water and provide it to the plant root system. Reduce the evaporation of water in the soil and improve the water use efficiency. The microorganisms inoculated in the microbial inoculation layer 204 can promote the absorption of nutrients by plants and improve the disease resistance of plants. It is helpful to establish and maintain the ecological balance of soil microorganisms. The clay layer 205 can prevent excessive water from penetrating into the anti-corrosion layer 206 below, and protect the anti-corrosion layer 206 from being eroded. Maintain a certain soil moisture and provide a stable water supply for plant growth. The anti-corrosion layer 206 prevents soil erosion and maintains the stability of the soil structure. Provide a solid foundation for the entire ecological protection layer 2.

[0029] The synergistic effect between the layers provides good growth conditions for plants, thereby improving the survival rate and growth rate of vegetation. Through layer-by-layer protection, the damage to the soil caused by wind erosion and water erosion is effectively reduced, and the ecological protection effect is enhanced. The water retaining agent layer 203 and the clay layer 205 work together to optimize the allocation and utilization of water resources. The reasonable construction of the ecological protection layer 2 helps to achieve the harmonious coexistence of photovoltaic power stations and the ecological environment and promote sustainable development.

[0030] In some embodiments, the desert ecological photovoltaic power station 100 of the embodiment of the present invention further includes a wind-proof and sand-fixing system, which is arranged around the photovoltaic array and is used to fix the ground surface around the photovoltaic array.

[0031] The wind and sand fixation system can effectively reduce the erosion of the surface around the photovoltaic array by wind and protect the infrastructure of the photovoltaic power station from damage. By fixing the sand, the wind and sand fixation system can prevent the occurrence of sandstorms, reduce the impact of sand and dust on photovoltaic panels 1, and maintain the efficiency of photovoltaic power generation. The existence of the wind and sand fixation system helps to improve the ecological environment in desert areas and provide stable conditions for the growth of vegetation. The wind and sand fixation system can reduce the risk of infrastructure damage caused by wind erosion and improve the operational safety of photovoltaic power stations.

[0032] Optionally, the windbreak and sand fixation system includes grass grids and a surface fixing net, the grass grids are arranged around the photovoltaic array, and the surface fixing net is used to be laid on the grass grids to fix the grass grids.

[0033] The grass grid can reduce the wind speed on the surface and reduce the erosion of the soil by wind. The grass grid structure helps to fix the sand and prevent the flying of sand and dust. The surface fixing net can fix the position of the grass grid to prevent the grass grid from being blown away or shifted by the wind. The combination of the surface fixing net and the grass grid improves the overall stability of the wind-proof and sand-fixing system.

[0034] In some embodiments, the desert ecological photovoltaic power station 100 of the embodiment of the present invention further includes an intelligent monitoring system, which is used to monitor the environmental parameters of the desert area and the operating status of the photovoltaic array in real time.

[0035] The intelligent monitoring system can collect environmental parameters such as temperature, humidity, wind speed, precipitation, etc. in the desert area in real time, and provide data support for the operation and maintenance of the power station. Through real-time monitoring, the system can detect abnormal environmental changes in time and start the early warning mechanism. The intelligent monitoring system can monitor the key performance indicators such as power generation and efficiency of the photovoltaic array to ensure the efficient operation of the photovoltaic power station. The system can detect faults and abnormalities of the photovoltaic array in time, quickly locate problems, and reduce troubleshooting time. According to changes in environmental parameters, the intelligent monitoring system can automatically adjust the angle or operation mode of the photovoltaic array to optimize power generation efficiency. The system can intelligently dispatch the operation of the power station according to actual conditions, such as adjusting cleaning and maintenance plans. The intelligent monitoring system can realize remote monitoring, reduce the number of on-site inspections by operation and maintenance personnel, and improve operation and maintenance efficiency. By analyzing the collected data, the system can provide a basis for operation and maintenance decisions and improve the quality and efficiency of operation and maintenance.

[0036] In some embodiments, the intelligent monitoring system includes multiple sensors, a data acquisition unit, a data processing unit and an early warning unit, and the sensors include a temperature sensor, a humidity sensor, a light sensor, a wind speed sensor and a soil moisture sensor.

[0037] The data acquisition unit is used to collect sensor data and transmit the data to the data processing unit. The data processing unit is used to analyze the sensor data and generate environmental parameter reports and photovoltaic power generation system status reports. The early warning unit is used to send environmental abnormality warnings or equipment failure warnings to power station managers based on the analysis results of the data processing unit.

[0038] Temperature sensors monitor ambient temperature and provide data for temperature management of photovoltaic arrays and regulation of cooling systems inside power stations. Humidity sensors monitor ambient humidity, which helps to assess air humidity and vegetation irrigation needs. Light sensors monitor light intensity and provide data support for optimizing photovoltaic power generation efficiency. Wind speed sensors monitor wind speed, which is essential for regulating wind and sand fixation systems and evaluating wind energy resources. Soil moisture sensors monitor soil moisture and provide data basis for intelligent regulation of automatic irrigation systems. The data acquisition unit collects sensor data in real time to ensure the accuracy and timeliness of the monitoring system. Data integration integrates data collected by different sensors for unified management and analysis. The data processing unit processes and analyzes the collected data, extracts useful information, and provides support for the operation decision-making of the power station. The processed data is stored for historical data query and long-term trend analysis. When abnormalities are detected in photovoltaic arrays or environmental parameters, fault warnings are issued in a timely manner. When safety hazards such as fire and theft are detected, the early warning mechanism is quickly activated.

[0039] The desert area ecological photovoltaic power station 100 of the embodiment of the present invention monitors the operating status of the photovoltaic array in real time, adjusts the operating parameters in time, and improves the power generation efficiency. The intelligent monitoring system helps to discover and solve potential problems in time, reducing failure and maintenance costs. By real-time monitoring of environmental parameters, the adaptability of the power station to environmental changes is improved and the stability is enhanced. The intelligent monitoring system provides a scientific basis for the operation and management of the power station, improves the management level and decision-making quality. By intelligently adjusting irrigation and power station operation, the use efficiency of water, electricity and other resources is optimized. Through real-time monitoring and early warning, the adverse impact of photovoltaic power stations on the environment is reduced.

[0040] In some embodiments, the photovoltaic array includes a photovoltaic panel 1, a support frame and a lifting assembly. The photovoltaic panel 1 is arranged on the support frame through the lifting assembly, and the lifting assembly is used to adjust the height of the photovoltaic panel 1.

[0041] In strong winds, the height of the photovoltaic panel 1 can be lowered to reduce the direct impact of wind on the photovoltaic panel 1 and enhance the stability of the photovoltaic array. In harsh environments, the lifting assembly can raise the photovoltaic panel 1 to reduce contact with the ground and reduce the risk of corrosion. The lifting assembly allows the photovoltaic panel 1 to adapt to different terrains and landforms, such as mountainous areas, hills and other areas with complex terrain. Vegetation can be planted under the photovoltaic panel 1, and the adjustment of the lifting assembly can reduce the obstruction of the vegetation, which is helpful for ecological protection.
