Description

Technical Field

[0001] The utility model relates to the field of photovoltaics, and in particular to a low wind resistance photovoltaic component mounting frame. Background Art

[0002] Photovoltaic modules are devices that use solar energy to convert light energy into electrical energy. When in use, they generally need to be placed in outdoor areas with sufficient sunlight. These areas are relatively open and often encounter strong winds. Existing photovoltaic modules are all installed on a fixed frame. Due to the large surface area of ​​photovoltaic modules, strong winds will form greater resistance on their surface. The pressure caused by strong winds can easily shorten the life of photovoltaic modules, and there is also a risk of them being overturned in extremely bad weather.

[0003] In order to reduce the wind resistance of photovoltaic modules, the applicant designed an articulated photovoltaic module. When the wind is strong from the front, the photovoltaic module can reduce the angle with the wind by rotating, thereby relieving the wind pressure and reducing the wind resistance. At the same time, a bow-shaped backboard is added to the back of the traditional photovoltaic panel to guide the back wind direction to the top and bottom of the photovoltaic module to avoid direct blowing, thereby reducing the back wind resistance. However, there is no suitable mounting frame in the prior art.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a low wind resistance photovoltaic component mounting frame that can be adapted to hingedly mounted photovoltaic components and has a significant wind resistance reduction effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a low wind resistance photovoltaic component mounting frame, comprising two symmetrically arranged vertical frames, the vertical frames comprising a support platform and a leg connected to the bottom of the support platform, the support platform comprising a bottom supporting arc rod, a horizontal rod and a rearward limiting rod, the bottom supporting arc rod is inclined from the front lower part to the rear upper part, the rear end of the bottom supporting arc rod is connected to the front end of the horizontal rod, and a hinged seat is arranged above the intersection of the bottom supporting arc rod and the horizontal rod; the bottom end of the rearward limiting rod is connected to the rear of the horizontal rod for limiting the rearward angle of the photovoltaic component.

[0007] Based on the above, the supporting legs include a front supporting leg, a middle supporting leg and a rear supporting leg. The bottom end of the front supporting leg is tilted forward, and the top end is connected to the front part of the bottom supporting arc rod. The bottom end of the middle supporting leg is tilted backward, and the top end is connected to the intersection of the bottom supporting arc rod and the horizontal rod. The bottom end of the rear supporting leg is tilted backward, and the top end is connected to the rear part of the horizontal rod.

[0008] Based on the above, a limiting groove for contacting with the photovoltaic component is provided on the front side of the rearward limiting rod.

[0009] Based on the above, a transverse brace is connected between the two reclining limit rods, between the two horizontal rods and between the two bottom supporting arc rods respectively.

[0010] Based on the above, the photovoltaic assembly includes a photovoltaic panel and an arched back panel, the top end of the arched back panel is connected to the top of the back side of the photovoltaic panel body, the bottom end of the arched back panel is connected to the bottom of the back side of the photovoltaic panel body, the middle part of the arched back panel is arched backward in an arc shape, and hinge columns are coaxially arranged on both sides of the middle part of the arched back panel; the hinge columns are hingedly installed on the hinge seat, and in a natural state, the bottom supporting arc rod supports the lower edge of the middle part of the arched back panel.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) By setting the hinged seat, the photovoltaic module can be hingedly connected. When the wind pressure on the front of the photovoltaic module is large, the photovoltaic module will be driven to rotate, reducing the angle with the wind, thereby achieving the effect of relieving the wind pressure. After the wind force decreases, it will return to its original position, thereby reducing the front wind resistance.

[0013] (2) The shape of the bottom supporting arc rod is consistent with the lower edge of the arched back plate, and the support is more stable in the natural state; when the photovoltaic module leans back, the limiting groove is convenient to contact with the arched back plate, which plays a role in limiting the leaning angle.

[0014] (3) The bottom end of the front leg is inclined forward, and the bottom ends of the middle leg and the rear leg are inclined backward. The provision of multiple cross braces enhances the strength of the mounting frame, and both further improve the support stability. BRIEF DESCRIPTION OF THE DRAWINGS
