Description

Technical Field

[0001] The utility model belongs to the field of solar power generation equipment, in particular to a solar power supply system for deserts with automatic cleaning and snow melting functions. Background Art

[0002] Environmental climate change and disaster warning in the desert are usually monitored by 24-hour automatic online monitoring equipment. Due to the lack of stable power supply in the desert environment, solar photovoltaic panels are usually used to power the detection equipment. However, the climate environment in the desert is relatively harsh, and the dust is large. The solar photovoltaic panels are exposed to the outside world for a long time, and a lot of dust will accumulate on them. If these dusts are not removed in time, it will affect the normal energy absorption of the solar panels. Due to factors such as being located in the desert, remote location, and unchanged transportation, manual cleaning is difficult. In the prior art, some solar photovoltaic panels are equipped with automatic cleaning devices, but they require water sources and cannot handle conditions such as snowfall and icing, so they are not suitable for cleaning solar photovoltaic panels in the desert. Utility Model Content

A mounting plate is arranged in the middle of the solar photovoltaic panel. The cleaning device comprises a profile mounting bar and a cleaning drive device. A brush is installed on the lower surface of the profile mounting bar. A rotating shaft penetrating the mounting plate is arranged in the middle of the profile mounting bar. The cleaning drive device comprises a driving motor fixed under the mounting plate, and the output shaft of the driving motor is connected to the rotating shaft through a coupling.

[0006] Preferably, a bearing is provided between the rotating shaft and the mounting plate.

[0007] Preferably, both ends of the profile mounting strip are provided with connecting seats, and rollers contacting the solar panel or screws with balls at the lower ends are installed in the connecting seats.

[0008] Preferably, the mounting plate is also provided with a proximity switch for detecting the profile mounting strip.

[0009] Preferably, a graphene heating film is provided on the lower surface of the solar photovoltaic panel.

[0010] Preferably, the drive motor is fixed on the mounting plate via a motor bracket, and a motor protective cover and a rear cover plate screwed onto the motor protective cover are arranged outside the drive motor.

[0011] Preferably, the brush comprises bristles and a bristle fixing plate, and two brush slots are provided on the lower surface of the profile mounting strip, and the bristle fixing plate is installed in the brush slots.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The solar power supply system for deserts described in the utility model can effectively remove sand and dust and other sediments on the surface of solar photovoltaic panels through the cleaning device, reduce obstruction, and enable solar photovoltaic panels to absorb sunlight more fully, thereby improving power generation efficiency and ensuring continuous power supply for electrical equipment in desert areas.

DETAILED DESCRIPTION

[0021] In order to better understand the present invention, a detailed description is given below in conjunction with the accompanying drawings and embodiments.

[0022] Example: Figure 1As shown, a solar power supply system for desert with automatic cleaning and snow melting function includes a bracket 1, a solar photovoltaic panel 2, a cleaning device and a control system. The upper surface of the bracket 1 forms an inclined surface, and the solar photovoltaic panel 2 is obliquely installed on the bracket 1. The solar photovoltaic panel 2 is divided into two left and right parts, and the two ends of the two solar photovoltaic panels 2 are connected by an end face horizontal plate 3, and a mounting plate 4 is also connected between the end face horizontal plates 3.

[0023] like Figure 2-5 As shown, the cleaning device includes a profile mounting strip 5 and a cleaning drive device. A brush 6 is installed on the lower surface of the profile mounting strip 5. The brush 6 includes a bristle fixing plate, and a plurality of bristles are arranged in sequence on the bristle fixing plate. Two brush card slots along the length direction are arranged on the lower surface of the profile mounting strip 5, and the bristle fixing plate is detachably installed in the brush card slot. A rotating shaft 7 is arranged in the middle of the profile mounting strip 5. The rotating shaft 7 passes through the mounting plate 4 and extends to the bottom of the mounting plate 4. A bearing 8 is arranged between the rotating shaft 7 and the mounting plate 4. The cleaning drive device includes a driving motor 9 fixed under the mounting plate 4, and the output shaft of the driving motor 9 is connected to the rotating shaft 7 through a coupling 10. The driving motor 9 is fixed on the mounting plate 4 through a motor bracket 11, and a motor protective cover 12 and a rear cover plate 13 screwed on the motor protective cover 12 are arranged outside the driving motor 9. The driving motor 9 is electrically connected to the control system. The driving motor 9 rotates to drive the profile mounting strip 5 to rotate around the rotating shaft 7, so that the brush 6 can clean the sediment on the surface of the solar photovoltaic panel 2 to keep the surface of the solar photovoltaic panel 2 clean.

[0024] In order to increase the stability of the profile mounting bar 5 during the rotation process, the profile mounting bar 5 is installed with a connecting seat 14 at both ends, and a roller that contacts the solar panel is installed in the connecting seat 14, or a screw 15 is screwed in the mounting seat, and a ball 16 is installed at the lower end of the screw 15. During the rotation process of the profile mounting bar 5, the roller and the ball 16 contact and roll with the upper surface of the solar photovoltaic panel 2, giving support force to the profile mounting bar 5 to prevent it from deformation.

[0025] The mounting plate 4 is also provided with a proximity switch 17 for detecting the profile mounting strip 5. The proximity switch 17 is electrically connected to the control system. The proximity switch 17 can detect the number of revolutions of the cleaning device. After reaching a preset number of revolutions, the cleaning is terminated and stops at the proximity switch 17.

[0026] The lower surface of the solar photovoltaic panel 2 is provided with a graphene heating film, which is electrically connected to the control system. When the outside weather is below zero degrees Celsius and it starts to snow, the low-power graphene heating film on the back of the solar photovoltaic panel 2 is activated to achieve the purpose of rapid snow melting and prevent ice from forming. For the convenience of remote control, a wireless communication device electrically connected to the control system is also provided, and the cleaning frequency can be adjusted through the wireless communication device according to the weather conditions.

[0027] The solar power supply system for deserts described in the utility model can effectively remove sand and dust and other sediments on the surface of the solar photovoltaic panel 2 through the cleaning device, reduce obstruction, and enable the solar photovoltaic panel 2 to absorb sunlight more fully, thereby improving power generation efficiency and ensuring continuous power supply for electrical equipment in desert areas. Keeping the solar panel clean and reducing erosion and damage to the panel body by dirt can extend the service life of the solar panel. Reduce the need for manual cleaning, reduce maintenance costs and labor intensity. Through the graphene heating film, snow and ice can be melted quickly to ensure that the solar photovoltaic panel 2 can operate normally under cold conditions.
