Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and more specifically, to a photovoltaic panel device with a snow removal function. Background Art

[0002] As the installed capacity of photovoltaic power stations continues to increase, mountainous and hilly areas will become the main sites for the construction of photovoltaic power stations. Since the construction sites in complex terrains such as mountains and hills have uneven surfaces and gullies, it is particularly easy to form snow. Photovoltaic panels built in mountains and hills will seriously affect their power generation efficiency when covered by snow.

[0003] In the related art, the snow covering the surface of photovoltaic panels is generally cleared by manual cleaning. However, due to the complex terrain, the cost of manual cleaning is high. If mechanical equipment is used to clean the snow, it cannot fully exert its effectiveness due to the terrain restrictions.

[0004] Therefore, how to design a photovoltaic panel bracket with automatic snow removal function is one of the problems that need to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 4 As shown, the photovoltaic panel device with snow removal function provided in the embodiment of the present application includes a ramp plate 100, a photovoltaic panel 300, a drive motor 500 and an eccentric wheel 600, wherein the ramp plate 100 is a device for fixing and supporting the photovoltaic panel 300, and the photovoltaic panel 300 is a device for converting solar energy into electrical energy. A cavity 110 is provided inside the ramp plate 100, and an opening 120 is provided on the upper surface of the ramp plate 100, and the area of ​​the opening 120 is smaller than the upper surface area of ​​the ramp plate 100. The photovoltaic panel 300 is installed at the opening 120 of the ramp plate 100, preferably, the area of ​​the photovoltaic panel 300 is larger than the area of ​​the opening 120, and the area of ​​the photovoltaic panel 300 is adapted to the upper surface area of ​​the ramp plate 100.

[0028] The ramp board 100 has a short side and a long side in the vertical direction. A first hinge 200 is fixedly provided at the short side of the ramp board 100. A second hinge 400 is fixedly provided at a position of the photovoltaic panel 300 close to the short side of the ramp board 100. The photovoltaic panel 300 is hingedly connected to the second hinge 400 of the ramp board 100 through the first hinge 200. Therefore, the photovoltaic panel 300 can rotate unilaterally with the short side of the ramp board 100 as the axis.

[0029] In this embodiment, the driving motor 500 is disposed on the side wall of the ramp plate 100, and the driving motor 500 is close to the long side direction of the ramp plate 100, such as Figure 3 As shown, the driving shaft of the driving motor 500 passes through the side wall of the ramp plate 100 and extends into the cavity 110. The eccentric wheel 600 is fixedly connected to the driving shaft of the driving motor 500, and the eccentric wheel 600 contacts the bottom surface of the photovoltaic panel 300. Preferably, a plurality of eccentric wheels 600 are fixedly connected to the driving shaft of the driving motor 500, and the plurality of eccentric wheels 600 are equidistantly distributed along the axis of the driving shaft, and all contact the bottom surface of the photovoltaic panel 300.

[0030] In the photovoltaic panel device with snow removal function provided in the embodiment of the present application, when it is necessary to clear the snow on the photovoltaic panel 300, the driving motor 500 can be started to drive the eccentric wheel 600 to rotate. Since the fixed end of the photovoltaic panel 300 is hingedly connected to the ramp plate 100 through the hinge structure, the eccentric wheel 600 will cause the free end of the photovoltaic panel 300 to perform periodic reciprocating vibrations during the rotation process, thereby realizing the function of vibrating the snow off the photovoltaic panel 300. The above structural design can not only realize the self-cleaning function of the photovoltaic panel device, but also greatly improve the efficiency of clearing the snow.

[0031] In some embodiments, a buffer column 700 is provided at the position where the upper surface of the ramp plate 100 contacts the free end of the photovoltaic panel 300. The buffer column 700 can reduce the hard contact between the free end of the photovoltaic panel 300 and the ramp plate 100, thereby greatly extending the service life of the photovoltaic panel 300.

[0032] In some embodiments, a snow collecting frame 800 is provided at the short side of the ramp plate 100, and the snow collecting frame 800 can collect the snow falling from the photovoltaic panel 300, so as to facilitate the subsequent directional treatment of the snow. Preferably, the two short sides of the snow collecting frame 800 can also be hinged with door panels 810, and the snow can be subsequently treated by opening the door panels 810.

[0033] In some embodiments, an electric heating wire 900 is disposed inside the bottom surface of the snow collecting frame 800. When the accumulated snow falls into the snow collecting frame 800, the electric heating wire 900 can be energized so that the accumulated snow can melt in the snow collecting frame 800. Figure 3 As shown, the bottom surface of the snow collecting frame 800 may be an inclined surface 820 inclined toward both sides in the length direction, so that the melted water can flow outwards easily.

[0034] In some embodiments, a screw rod 130 and a positioning rod 140 are respectively disposed on both sides of the upper surface of the ramp plate 100. Figure 4As shown, a brush body 150 is further provided between the screw rod 130 and the positioning rod 140, and the bottom surface of the brush body 150 contacts the upper surface of the photovoltaic panel 300. When the screw rod 130 rotates, the brush body 150 can be driven to slide along the upper surface of the ramp plate 100, so that the snow adhering to the photovoltaic panel 300 can be cleaned.
