Technical Field
[0001] The present invention relates to the technical field of photovoltaic desert control, and more specifically, to a photovoltaic desert control device. Background Art
[0002] Desertification has always been the biggest obstacle to the development of western China. Desert control in the west has always been a major project for China over the centuries. The country has invested a lot of energy and funds in desert control, and new desert control models have been continuously explored in China. Photovoltaic desert control is the latest achievement explored in the second decade of the 21st century. The photovoltaic desert control device realizes the win-win of economic and ecological benefits by installing water-saving drip irrigation facilities under the photovoltaic panels and planting green cash crops. However, the existing photovoltaic desert control devices have the following deficiencies: when the photovoltaic desert control device conducts mobile water-saving drip irrigation in the desert, the photovoltaic desert control device is prone to tipping over, resulting in the inability of the photovoltaic desert control device to stably walk in the desert for water-saving drip irrigation of planting green cash crops, and the wind and sand in the desert are more likely to cover the photovoltaic panels, resulting in the reduction of the area of the photovoltaic panels receiving sunlight and the reduction of the power generation capacity to provide power for the photovoltaic desert control device. Summary of the Invention
[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a photovoltaic desert control device, the structure of which includes a box body, a support mechanism, and a photovoltaic panel. There are four support mechanisms, and two of them are set as a group at the front and rear ends of the box body respectively. The photovoltaic panel is installed directly above the box body, and a moving wheel is provided at each of the four corners of the bottom of the box body. The support mechanism is composed of a hinge block, a spring tube sleeve, a pressing rod, a hinge plate, and a support wheel. The hinge block is fixed on the surface of the box body, and the upper end of the spring tube sleeve is hinged inside the hinge block. The pressing rod is elastically pressed inside the spring tube sleeve through a spring arranged inside the spring tube sleeve. The lower end of the pressing rod is provided with a hinge plate axially connected to the support wheel. The support mechanism is inclined as a whole on the outside of the box body, and the spring tube sleeve and the pressing rod on the four support mechanisms at the front and rear ends of the box body are elastically matched.
[0004] As a further improvement of the present invention, a water collecting port is provided at the upper end of the box body, and a water inlet is arranged inside the water collecting port and is connected to the water tank inside the box body in a through manner. Clamping grooves are embedded at the upper ends of both sides of the water collecting port. A filter plate is installed inside the water collecting port, and clamping rods are provided at both ends of the filter plate. The clamping rods are clamped inside the clamping grooves. The inside of the water collecting port is of an inclined surface structure, and the water inlet is located at the lowest water level inside the water collecting port to ensure that the water source is fully guided and discharged into the water tank.
[0005] As a further improvement of the present invention, a water pump is further provided outside the water tank. The water pump is located inside the box body, and the water pump transports the water source inside the water tank to the inside of the spraying mechanism installed outside the box body. The spray pipe provided on the spraying mechanism is fixed outside the box body, and a convex block is embedded inside the spray pipe. A plurality of spray heads are arranged and distributed at the bottom of the spray pipe. There are six spray pipes, and three of them are in a group and are respectively distributed at both ends outside the box body, and the convex blocks inside the spray pipe are in a pressurized state.
[0006] As a further improvement of the present invention, a splash guard is further provided below the spray pipe, and the spray head is located inside the splash guard. A torsion shaft is provided inside the splash guard, and one end of a shielding piece that abuts against the bottom surface of the spray head is hinged through the torsion shaft. The splash guard has a cover body structure that is narrow at the upper end and wide at the lower end, which can prevent the water mist from being sprayed upward and blown by the wind when the spray head atomizes water, and cannot effectively spray the planted green economic crops. And a rotational torsion elasticity is applied to the shielding piece through the torsion shaft at the bottom.
[0007] As a further improvement of the present invention, there are two photovoltaic panels, and a support frame is provided at the connection of the two photovoltaic panels. The two photovoltaic panels are supported directly above the box body through the support frame. The photovoltaic panels are electrically connected to the electricity storage box installed on the upper surface of the box body, and a cleaning mechanism is further provided at the edge of the photovoltaic panel; The cleaning mechanism is composed of a blower, an air inlet pipe, a diversion pipe, a shunt pipe and a jet nozzle. The blower is fixedly installed on the side of the box body, and the air inlet pipe is embedded at the lower end of the blower. The upper end inside the blower is connected to the lower end of the diversion pipe in a through manner. The upper end of the diversion pipe is connected to the middle of the diversion pipe, and a jet nozzle is embedded on the surface of the diversion pipe. The jet nozzle is located at the edge of the photovoltaic panel. The blower is electrically connected to the electricity storage box. There are two diversion pipes and two shunt pipes, and five jet nozzles are embedded on each of the two shunt pipes.
[0008] As a further improvement of the present invention, a dust-proof cover is provided at the outer end of the air inlet pipe and the two are connected by threads. An elastic filter screen is installed inside the dust-proof cover, and the elastic filter screen matches the inner diameter of the dust-proof cover.
[0009] The beneficial effects of the present invention are as follows: 1. Through the elastic cooperation of the spring tube sleeve and the extrusion rod on the four support mechanisms at the front and rear ends of the box body, the support wheels can perform elastic adjustment and support at the front and rear ends outside the box body, effectively preventing the box body from tipping over, and the support wheels assist the moving wheels to drive the box body to move stably on the desert; 2. The convex blocks inside the spray pipe are in a pressurized state, accelerating the speed of the water source spraying out from the spray head. Thus, the water source inside the water tank is atomized and sprayed out through the multiple spray heads at the lower ends of the six spray pipes, increasing the spraying area of the water source for the green economic crops planted in the desert, and ensuring the full survival of the green economic crops planted in the desert; 3. Apply rotational torsion elasticity to the shielding piece through the torsion shaft at the bottom, so that the shielding piece rotates downward when the nozzle sprays water, ensuring normal water spraying work. When the nozzle stops spraying water, the shielding piece rotates upward to reset and shield the nozzle, preventing the nozzle from getting wet and causing the sand in the desert to adhere to the lower end of the nozzle to form lumps, which affects the normal water spraying work of the nozzle next time. 4. Generate wind energy through the blower and discharge the wind energy from two diversion pipes into the inside of the shunt pipe and finally spray it out from the inside of the air nozzle to clean the surfaces of the two photovoltaic panels, effectively preventing the sand in the desert from covering the photovoltaic panels and ensuring that the photovoltaic panels maintain normal power generation capacity.

Detailed Embodiment
[0017] The following further describes the present invention with reference to the accompanying drawings: Embodiment
[0018] As shown in Figure 1 to Figure 6 shown: A photovoltaic sand control device of the present invention, its structure includes a box body 1, a support mechanism 2, and a photovoltaic panel 3. There are four support mechanisms 2, and two of them are set as a group and are respectively arranged at the front and rear ends of the box body 1. The photovoltaic panel 3 is installed directly above the box body 1, and a moving wheel 15 is provided at each of the four corners of the bottom of the box body 1. The support mechanism 2 is composed of a hinge block 21, a spring tube sleeve 22, a pressing rod 23, a hinge plate 24, and a support wheel 25. The hinge block 21 is fixed on the surface of the box body 1, and the upper end of the spring tube sleeve 22 is hinged to the inside of the hinge block 21. The pressing rod 23 is elastically pressed inside the spring tube sleeve 22 through a spring arranged inside the spring tube sleeve 22. The lower end of the pressing rod 23 is provided with a hinge plate 24 which is axially connected to the support wheel 25. The upper end of the box body 1 is provided with a water collecting port 12, and a water inlet 122 is arranged inside the water collecting port 12 and is connected to the water tank 13 inside the box body 1 in a through manner. Clamping grooves 121 are embedded at the upper ends of both sides of the water collecting port 12. A filter plate 123 is installed inside the water collecting port 12, and clamping rods 124 are provided at both ends of the filter plate 123. The clamping rods 124 are clamped inside the clamping grooves 121. A water pump 14 is further arranged outside the water tank 13. The water pump 14 is located inside the box body 1, and the water pump 14 transports the water source inside the water tank 13 to the inside of a spraying mechanism 11 installed outside the box body 1. A spray pipe 111 provided on the spraying mechanism 11 is fixed outside the box body 1, and a convex block 112 is embedded inside the spray pipe 111. A plurality of spray heads 113 are arranged in a row at the bottom of the spray pipe 111. A splash-proof cover 114 is further arranged below the spray pipe 111, and the spray heads 113 are located inside the splash-proof cover 114. A torsion shaft 115 is arranged inside the splash-proof cover 114, and one end of a shielding piece 116 that abuts against the bottom surface of the spray head 113 is hinged through the torsion shaft 115.
[0019] As a further improvement of the present invention, there are two photovoltaic panels 3, and a support frame 31 is arranged at the connection of the two photovoltaic panels 3. The two photovoltaic panels 3 are supported directly above the box body 1 through the support frame 31. The photovoltaic panel 3 is electrically connected to a power storage box 32 installed on the upper surface of the box body 1, and a cleaning mechanism 33 is further arranged at the edge of the photovoltaic panel 3; the cleaning mechanism 33 is composed of a blower 331, an air inlet pipe 332, a diversion pipe 333, a shunt pipe 334, and a jet nozzle 335. The blower 331 is fixedly installed on the side of the box body 1, and the air inlet pipe 332 is embedded at the lower end of the blower 331. The upper end inside the blower 331 is connected to the lower end of the diversion pipe 333 in a through manner. The upper end of the diversion pipe 333 is connected to the middle of the diversion pipe 333, and jet nozzles 335 are embedded on the surface of the diversion pipe 333. The jet nozzles 335 are located at the edge of the photovoltaic panel 3. The blower 331 is electrically connected to the power storage box 32. A dust-proof cover 3321 is arranged at the outer end of the air inlet pipe 332 and the two are connected by threads. An elastic filter screen 3322 is installed inside the dust-proof cover 3321; In the present invention, water source is added or collected from rainfall through the water inlet 12, and the water source is discharged into the interior of the water tank 13. The photovoltaic panel 3 above receives sunlight for power generation, and the electric energy is stored in the electricity storage box 32. The moving wheels 15 provided at the bottom of the box body 1 drive the box body 1 to move in the desert. During the moving process, the water pump 14 is started to convey the water source in the water tank 13 into the spray pipe 111 and finally atomized and sprayed out from the spray head 113 to water the green cash crops planted in the desert. When the device moves and waters in the desert, the spring tube sleeve 22 and the extrusion rod 23 on the four support mechanisms 2 at the front and rear ends of the box body 1 are elastically matched, so that the support wheels 25 can elastically adjust the support at the front and rear ends outside the box body 1, effectively preventing the box body 1 from tipping over. And the support wheels 25 assist the moving wheels 15 to drive the box body 1 to move stably in the desert. When the photovoltaic panel 3 receives sunlight for power generation, the sandy soil in the desert is likely to cover the surface of the photovoltaic panel 3. At this time, the blower 331 is started to generate wind energy. The wind energy is discharged into the shunt pipe 334 from the two diversion pipes 333 and finally sprayed out from the air jet nozzle 335 to clean the surfaces of the two photovoltaic panels 3, effectively preventing the sandy soil in the desert from covering the photovoltaic panel 3 and ensuring that the photovoltaic panel 3 maintains normal power generation capacity.
[0020] In a preferred technical solution, the support mechanism 2 is inclined as a whole outside the box body 1. The spring tube sleeve 22 and the extrusion rod 23 on the four support mechanisms 2 at the front and rear ends of the box body 1 are elastically matched, so that the support wheels 25 can elastically adjust the support at the front and rear ends outside the box body 1, effectively preventing the box body 1 from tipping over. And the support wheels 25 assist the moving wheels 15 to drive the box body 1 to move stably in the desert; In a preferred technical solution, the interior of the water inlet 12 has an inclined surface structure. The water inlet 122 is located at the lowest water level inside the water inlet 12 to ensure that the water source is fully guided and discharged into the interior of the water tank 13. And the filter plate 123 is stably installed inside the water inlet 122 by engaging the engaging rods 124 on both sides of the filter plate 123 into the engaging grooves 121 to filter the artificially added water source or the water source collected during rainfall, preventing the sandy soil in the desert from entering the interior of the water tank 13; In a preferred technical solution, there are six spray pipes 111, and three of them are in a group and are respectively distributed at both ends outside the box body 1. The convex blocks 112 inside the spray pipe 111 are in a pressurized state, accelerating the speed of the water source sprayed out from the spray head 113. Thus, the water source in the water tank 13 is atomized and sprayed out through the multiple spray heads 113 at the lower ends of the six spray pipes 111, increasing the area of the water source sprayed on the green cash crops planted in the desert and ensuring the full survival of the green cash crops planted in the desert; A preferred technical solution is that the splash guard 114 has a cover structure that is narrow at the upper end and wide at the lower end. It can prevent the water mist from spraying upward when the nozzle 113 atomizes water and being blown by the wind, so that it cannot effectively spray the planted green economic crops. And through the torsion shaft 115 at the bottom, rotational torsion elasticity is applied to the shielding piece 116, so that the shielding piece 116 rotates downward when the nozzle 113 sprays water, ensuring normal spraying work. When the nozzle 113 stops spraying water, the shielding piece 116 rotates upward and resets to shield the nozzle 113 to prevent the nozzle 113 from getting wet, so that the sandy soil in the desert adheres to the lower end of the nozzle 113 to form lumps, which affects the normal spraying work of the nozzle 113 next time. A preferred technical solution is that there are two diversion pipes 333 and two shunt pipes 334. Five air nozzles 335 are embedded on each of the two shunt pipes 334. The blower 331 generates wind energy and discharges the wind energy from the two diversion pipes 333 into the shunt pipes 334 and finally sprays it out from the air nozzles 335 to clean the surfaces of the two photovoltaic panels 3, effectively preventing the sandy soil in the desert from covering the photovoltaic panels 3 and ensuring that the photovoltaic panels 3 maintain normal power generation capacity. A preferred technical solution is that the elastic filter screen 3322 matches the inner diameter of the dust-proof cover 3321. When the blower 331 works and sucks the external air into the intake pipe 332, the elastic filter screen 3322 sinks inward, improving the effect of filtering the sandy soil in the air. And when the blower 331 stops working, the elastic filter screen 3322 rebounds, and can eject the filtered sandy soil, reducing the sandy soil covering the surface of the elastic filter screen 3322, so that the elastic filter screen 3322 achieves the self-cleaning effect. Using the technical solution of the present invention, or those skilled in the art being inspired by the technical solution of the present invention to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present invention.
