[0002] Due to their unique climate, desert regions suffer from water scarcity, infertile soil, and difficulties in power transmission, posing significant challenges to agricultural production. Traditional irrigation and fertilization methods are not only inefficient but also often fail to meet the growth needs of crops in desert areas. Therefore, developing equipment that can adapt to the special environment of desert regions and efficiently utilize solar energy resources for irrigation and fertilization is particularly important. This utility model is proposed against this background, aiming to solve the problems of agricultural irrigation and fertilization in desert regions through innovative technological means, improve agricultural production efficiency, and promote agricultural development in desert areas.

[0003] Because existing agricultural irrigation and fertilization equipment mostly relies on traditional energy sources, it is not only energy-intensive, but also often restricted in operation in desert areas where power supply is unstable, which is detrimental to the sustainable development of agriculture in desert areas. The solar-powered irrigation and fertilization equipment for desert areas proposed in this utility model realizes the automation and intelligence of the irrigation and fertilization process by utilizing abundant solar energy resources. It not only improves energy utilization efficiency and reduces operating costs, but also cleans the photovoltaic panels to prevent impurities from adhering to the surface of the photovoltaic panels and affecting light transmittance in harsh environments, thereby further improving the conversion efficiency of solar energy, ensuring the long-term stable operation of the equipment, and reducing the cost of manual irrigation and power consumption in harsh environments.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a solar irrigation and fertilization device for desert areas, including a base 1, a water and fertilizer tank 2 fixedly connected to the top of the base 1, irrigation nozzles 3 fixedly connected to all four sides of the water and fertilizer tank 2, an electrical box 4 installed on the top of the base 1, a mounting frame 5 fixedly connected to the top of the base 1, a controller 6 installed on one side of the mounting frame 5, a photovoltaic panel 7 rotatably connected to the top of the mounting frame 5 via a shaft, sliding rods 8 fixedly connected to both sides of the mounting frame 5, a sliding plate 9 slidably connected to the surface of the sliding rods 8, a brush 10 fixedly connected to one side of the sliding plate 9, the brush 10 abutting against the surface of the photovoltaic panel 7, absorbing solar energy through the photovoltaic panel 7. Light is converted into electrical energy and stored in the power box 4 to provide power for the device. The power box 4 and the irrigation nozzle 3 are then controlled by the controller 6 to spray water and fertilizer in all directions to achieve irrigation and fertilization. When the surface of the photovoltaic panel 7 is covered with mud and sand, the staff pulls the sliding plate 9 upward and slides it on the surface of the sliding rod 8, so that the brush 10 is attached to the surface of the photovoltaic panel 7. The brush 10 rubs the surface of the photovoltaic panel 7, so that the mud and sand attached to the surface of the photovoltaic panel 7 can be removed by the brush 10. This prevents the photovoltaic panel 7 from being covered with mud and sand and affecting the light energy absorption efficiency when the device is used in harsh environments for a long time. This makes it easier for the staff to clean the photovoltaic panel 7 and ensure the cleanliness of the surface of the photovoltaic panel 7.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown in this embodiment: a water spraying device 11 is installed on the top of the mounting frame 5, and several water spray heads 12 are installed on the bottom of the water spraying device 11. A water tank 13 is fixedly connected to the top of the base 1. One side of the water spraying device 11 is connected to the water tank 13 through a water supply pipe. A drive pump 14 is installed on one side of the water tank 13. The drive pump 14 operates to pump clean water from inside the water tank 13 into the water spraying device 11 through the water supply pipe. When the clean water is sprayed onto the surface of the photovoltaic panel 7 through the water spray heads 12, the water spray heads 12 can rinse the surface of the photovoltaic panel 7 from top to bottom, washing away the chemical substances in the fertilizer adsorbed on the surface of the photovoltaic panel 7, preventing the surface of the photovoltaic panel 7 from being corroded and damaged due to long-term adsorption of fertilizer. At the same time, the water spraying heads 12 spray clean water to rinse the photovoltaic panel 7 can improve the self-cleaning effect of this device.

[0023] Reference Figure 2 and Figure 5 As shown in this embodiment: a support plate 15 is fixedly connected to one side of the mounting frame 5. Two electric telescopic rods 16 are installed on one side of the support plate 15. The top of the electric telescopic rods 16 is rotatably connected to one side of the photovoltaic panel 7 via a hinge. Through the support plate 15 and the electric telescopic rods 16, when the electric telescopic rods 16 are running with the power supply from the electrical box 4, the electric telescopic rods 16 can retract and push one side of the photovoltaic panel 7 upward, raising one side of the photovoltaic panel 7 so that the photovoltaic panel 7 can rotate out from inside the mounting frame 5 and rotate to a horizontal position with the mounting frame 5, increasing the solar radiation receiving area of ​​the photovoltaic panel 7. At the same time, the use of electric telescopic rods 16 allows the photovoltaic panel 7 to adjust its angle and raise its height, making it easier for staff to maintain the photovoltaic panel 7.

[0024] Reference Figure 4 As shown in this embodiment: both ends of one side of the slide plate 9 are fixedly connected to extension plates 17. The interior of the extension plates 17 is rotatably connected to a rotating plate 18. A sponge wiping device 19 is fixedly connected to one side of the rotating plate 18. When the operator rotates the rotating plate 18 along the extension plates 17, the sponge wiping device 19 is made to adhere to the surface of the photovoltaic panel 7. Then, the rotating plate 18 is pushed upward, so that the rotating plate 18 can move upward through the sliding connection between the slide plate 9 and the slide rod 8, so that the sponge wiping device 19 can wipe the surface of the photovoltaic panel 7 and absorb the moisture or dirt on the surface of the photovoltaic panel 7. This prevents water stains from remaining after rinsing the photovoltaic panel 7, which would affect the light transmittance of the photovoltaic panel 7, and prevents residual water stains from re-absorbing mud and sand, thus affecting the power generation efficiency.

[0025] Reference Figure 5As shown in this embodiment, the mounting frame 5 has three openings 20, which pass through the mounting frame 5. The 20s make the middle part of the mounting frame 5 a ventilation area. In strong winds, the wind can circulate through the 20s, preventing the device from being blown over by strong winds due to obstruction of the mounting frame 5. This improves the service life of the device in severe weather. At the same time, the design of the 20s can also promote air convection in the mounting frame 5, effectively dissipate heat from the photovoltaic panel 7, and reduce the equipment failure rate caused by high temperature. In addition, the opening of the 20s also prevents impurities from accumulating inside the mounting frame 5.

[0026] Reference Figure 6 As shown in this embodiment, several water nozzles 12 are installed at an angle of 10° at the bottom of the water spraying device 11. This angled installation ensures that the water is sprayed at an angle, allowing the water to be precisely sprayed onto the top of the photovoltaic panel 7. This ensures that the water is evenly covered on the surface of the photovoltaic panel 7. The angled spraying method also reduces water evaporation, ensuring that every drop of water is effectively utilized. This design is particularly important in desert areas where water resources are precious. In addition, the angled installation of the water nozzles 12 can also prevent wind and sand from clogging the spray nozzles to a certain extent, maintaining the continuous and stable operation of the equipment and further improving its reliability and durability.

[0027] Working Principle: The photovoltaic panel 7 absorbs sunlight and converts it into electrical energy, which is stored in the power box 4 to power the device. The controller 6 then drives the power box 4 and the irrigation nozzles 3 to spray water and fertilizer in all directions for irrigation and fertilization. When sediment adheres to the surface of the photovoltaic panel 7, the operator pulls the sliding plate 9 upwards, causing the brush 10 to adhere to the surface of the photovoltaic panel 7. The brush 10 rubs against the surface of the photovoltaic panel 7, removing the sediment and preventing it from being covered by sediment during long-term use in harsh environments, thus ensuring the surface cleanliness of the photovoltaic panel 7 and facilitating cleaning. The pump 14 drives the pump to operate the water tank 13. Clean water enters the water spraying device 11 through the water supply pipe, and is then sprayed onto the surface of the photovoltaic panel 7 through the spray nozzle 12. This allows the spray nozzle 12 to rinse the surface of the photovoltaic panel 7 from top to bottom, washing away the chemicals adsorbed from the fertilizer and preventing corrosion damage caused by long-term fertilizer adsorption. Simultaneously, the spraying of clean water from the spray nozzle 12 improves the self-cleaning effect of the device. Through the support plate 15 and the electric telescopic rod 16, when the electric telescopic rod 16 is powered by the electrical box 4, it retracts, pushing one side of the photovoltaic panel 7 upwards, lifting it so that the photovoltaic panel 7 can rotate out of the mounting frame 5. The photovoltaic panel 7 is moved to a horizontal position with the mounting frame 5, increasing its solar energy reception area. Simultaneously, an electric telescopic rod 16 allows the photovoltaic panel 7 to be adjusted in angle for lowering and then raised, facilitating maintenance. By rotating the rotating plate 18 along the extension plate 17, the sponge 19 adheres to the surface of the photovoltaic panel 7. Pushing the rotating plate 18 upwards allows it to move through the sliding connection between the sliding plate 9 and the sliding rod 8, enabling the sponge 19 to wipe the surface of the photovoltaic panel 7, absorbing moisture and dirt. This prevents water stains from remaining after rinsing, which could affect the light transmittance of the photovoltaic panel 7 and prevent residual water from re-absorbing dirt and affecting power generation efficiency. The design of the bracket 20 creates a ventilation area in the middle of the mounting frame 5. In strong winds, wind can circulate through the bracket 20, preventing the device from being blown over by strong winds and extending its lifespan in harsh weather. The design of the bracket 20 also promotes air convection within the mounting frame 5, effectively dissipating heat from the photovoltaic panel 7 and reducing equipment failure rates due to high temperatures. Furthermore, the bracket 20 prevents the accumulation of impurities inside the mounting frame 5. The tilted installation of the water nozzles 12 ensures that the water is sprayed at an angle, precisely targeting the top of the photovoltaic panel 7 and ensuring even coverage. This tilted spraying method also reduces water evaporation.Ensuring that every drop of water is used effectively is crucial, especially in desert regions where water resources are precious. The angled spray head 12 also helps prevent wind and sand from clogging the spray nozzles, maintaining the equipment's continuous and stable operation and further enhancing its reliability and durability.
