Description

Technical Field

[0001] The present application relates to the technical field of solar power supply, and in particular to an off-grid solar photovoltaic power supply system. Background Art

[0002] Existing lighting equipment and monitoring equipment require electricity supply, but since some places that require lighting or monitoring are not convenient for circuit wiring, an off-grid power supply mode is usually adopted, that is, solar energy is used for power supply. Existing solar power supply mostly uses a combination of photovoltaic panels and batteries to power electrical equipment.

[0003] CN117157874A discloses a solar rotating module, which improves the lighting efficiency and reduces the probability of foreign matter accumulating on the solar panel surface by rotating the solar panel. However, it removes the attachments on the panel surface through continuous rotation, resulting in high energy consumption. Summary of the invention

[0004] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide an off-grid solar photovoltaic power supply system, which has the advantage of low energy consumption.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0006] An off-grid solar photovoltaic power supply system comprises a bracket, wherein an air bag and a mounting plate are arranged on the bracket, the lower surface of the air bag is fixedly mounted on the bracket, the mounting plate is fixedly mounted on the upper surface of the air bag, the mounting plate is used for mounting a solar panel, and an exhaust valve is arranged on the air bag.

[0007] By adopting the above technical solution, when there are impurities on the surface of the solar panel during use, the gas in the airbag is discharged. When the gas in the airbag is completely discharged, the solar panel is tilted during use, so it will slide under the action of gravity, and the impurities attached to the solar panel will have an initial velocity, making it easier to slide off the solar panel. In this process, the movement of the solar panel relies on gravity, so it has lower energy consumption.

[0008] In a preferred example, the present application can be further configured as follows: a plurality of unconnected chambers are provided in the airbag, and each chamber corresponds to an exhaust valve.

[0009] By adopting the above technical solution, the presence of multiple chambers ensures that even if an airbag is damaged during use, it can still provide a good supporting effect.

[0010] In a preferred example, the present application can be further configured to: adjust the exhaust of the corresponding airbag according to the weather, thereby adjusting the tilt angle of the solar panel.

[0011] By adopting the above technical solution, that is, by adjusting the exhaust of the airbag, the tilt angle of the solar panel can be adjusted, thereby reducing the probability of debris adhering to the solar panel in special weather.

[0012] In a preferred example, the present application can be further configured to: receive weather information, and if it is snowing, the gas in the airbag gradually decreases from one end of the solar panel to the other end.

[0013] By adopting the above technical solution, the tilt angle of the solar panel is increased, so that it is more difficult for snow to adhere to the surface of the solar panel in snowy weather.

[0014] In a preferred example, the present application can be further configured as follows: after the snowy weather stops, the exhaust valves in all airbags open to discharge the gas.

[0015] By adopting the above technical solution, during use, the solar panel is tilted, so under the action of gravity, the solar panel will slide, and the snow attached to the solar panel will have an initial velocity, making it easier to slide off the solar panel.

[0016] In a preferred example, the present application can be further configured as follows: when the gas in the airbag is discharged, the power supply is detected and the weather conditions are obtained. If the weather meets the standards and the power supply is greater than a preset value, the pressurizing device is started to pressurize the airbag.

[0017] By adopting the above technical solution, that is, when the lighting conditions are good and the power supply is greater than a preset value, the airbag is pressurized by the pressurizing device, so that the solar panel is reset.

[0018] In a preferred example, the present application can be further configured as follows: when the power reaches a limited value or the airbag pressure reaches a preset value, the pressurizing device stops working.

[0019] By adopting the above technical solution, when the power supply reaches a limited value, the pressurizing device stops working, thereby achieving the purpose of giving priority to load power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-Figure 3 , which is an off-grid solar photovoltaic power supply system disclosed in the present application, includes a control system, a power source (battery), a solar panel 4, a load and a bracket 1, an airbag 2 and a mounting plate 3 are provided on the bracket 1, the lower surface of the airbag 2 is fixedly mounted on the bracket 1, the mounting plate 3 is fixedly mounted on the upper surface of the airbag 2, the mounting plate 3 is used to mount the solar panel 4, and an exhaust valve is provided on the airbag 2.

[0026] The solar panel 4 is used to supply energy to the power supply / load, and the power supply is used to supply energy to the load. In this embodiment, the load includes but is not limited to a control system, a camera, a lighting lamp, a network device and a pressurizing device. In this embodiment, the pressurizing device is an air pump.

[0027] A partition layer is provided in the airbag 2, and the partition layer is made of rubber material. The airbag 2 is divided into a plurality of unconnected chambers 21, and each chamber 21 is equipped with an exhaust valve. In the present embodiment, the plurality of chambers 21 are divided into two rows, and a mounting groove 31 for mounting a solar panel 4 is provided on the mounting plate 3. An air outlet 32 ​​is also provided on the mounting plate 3, and the air outlet 32 ​​can be connected to one or more exhaust valves. The air outlet 32 ​​and the mounting groove 31 are connected to blow the surface of the solar panel 4.

[0028] The control system receives weather information through the network. When snow is forecasted, the airbag 2 is adjusted to exhaust gas so that the gas in the airbag 2 gradually decreases from one end of the solar panel 4 to the other end (see Figure 3 ,by Figure 3 Taking the position of the airbag 2 as an example, the pressure of the chamber 21 in the middle position gradually decreases to the lowest chamber 21 (corresponding to the lowest end in the tilted state during use), and the pressure of the chamber 21 in the middle position gradually decreases to the highest chamber 21, and the pressure of the chamber 21 in the highest chamber 21 gradually increases. At this time, the pressure in the highest chamber 21 is the cleaning value). Thus, the tilt angle of the solar panel 4 is increased.

[0029] After the snowy weather ends, the control system determines the power level of the power supply. If the power level of the power supply is greater than the preset value, the pressurizing device is started to pressurize the airbag 2, and the pressure in the airbag 2 reaches the cleaning value. When the cleaning value is reached, the control system controls all exhaust valves to open, so that the gas is discharged from the air outlet 32. In this process, the gas in the airbag 2 is rapidly reduced in a short time, so the support plate will move downward, and when the gas in the airbag 2 is discharged more, the support plate moves obliquely downward under the action of gravity. In this process, it can have a good effect on removing snow. In use, the surface of the solar panel 4 can be imaged. When there is a lot of snow, when the power level of the power supply is greater than the preset value, the exhaust step can be performed multiple times.

[0030] After the gas in the airbag 2 is discharged, the control system detects the power supply and obtains the weather conditions. If the weather meets the standards (that is, the light intensity meets the requirements, such as non-rainy or snowy weather or non-cloudy weather), and the power is greater than the preset value, the pressurizing device is started to pressurize the airbag 2 and pressurize it to the standard value (the pressure corresponding to the cleaning value is greater than the pressure corresponding to the standard value). When the power reaches the limit value or the air pressure of the airbag 2 reaches the preset value (standard value), the pressurizing device stops working.

[0031] The implementation principle of this embodiment is: since the solar panel 4 is tilted when in use, the solar panel 4 will slide under the action of gravity, so that the debris attached to the solar panel 4 has an initial velocity, making it easier to slide off the solar panel 4.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
