Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panels, and in particular relates to a snow barrier structure for a solar photovoltaic panel. Background Art

[0002] Currently, to meet the power generation needs of solar photovoltaic panels, they are installed at an angle to receive sunlight. In some areas, heavy snowfall can cause a thick layer of snow to accumulate on the panels. As the heat generated by the panels melts, the accumulated snow slides down the tilt of the panels. Since solar photovoltaic panels are often installed on rooftops, large amounts of snow can fall from high altitudes, potentially causing personal injury and property damage. Therefore, snow barriers are necessary to prevent this from happening.

[0003] Existing snow protection structures such as Figure 1-3 As shown, it includes a snow guard bracket 1' and a snow guard net 2'. The snow guard bracket is fixed to the low end side of the photovoltaic panel 3', that is, the part close to the eaves. The snow guard net is fixed to the snow guard bracket by bolts 4'. Figure 2 As shown, the top of the snow guard bracket is provided with a clamping portion 5' and a bayonet 6' on the side facing the photovoltaic panel. The upper part of the snow guard net is provided with an opening. When installing the snow guard net, the snow guard net needs to be adjusted to a certain angle so that the clamping portion can pass through the opening and the snow guard net can be clamped with the bayonet. The specific structure can be referred to patent CN219080773U. This structure makes the installation of the snow guard net troublesome, and the bottom of the snow guard net has no support, and the structure is not stable enough. In addition, if Figure 1 and Figure 3 As shown, the bolt fixing plane 7' is perpendicular to the photovoltaic panel. When locking the bolt, the worker must lean forward on the roof to lock the bolt, which makes the installation troublesome and slow. Utility Model Content

This allows the bolts to be installed at an angle, which is more suitable for installation workers. Workers can install the bolts without leaning forward, making snow screen installation easier and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 4-8 As shown, the utility model provides a snow-blocking structure for a solar photovoltaic panel, comprising a roof 1, a snow-blocking bracket 2 and a snow-blocking net 3. A photovoltaic panel 4 is fixed obliquely on the roof 1. The roof 1 is specifically composed of a plurality of oblique beams 5 arranged obliquely. A cross beam 6 is provided on the oblique beam 5. The cross beam 6 is placed perpendicular to the oblique beam 5. The photovoltaic panel 4 is fixed on the cross beam 6 and is parallel to the oblique beam 5. The photovoltaic panel 4 is also arranged obliquely, and its two ends form a high end and a low end 41. The high end is the highest position of the roof 1, and the low end 41 is the lowest position close to the eaves; a snow-blocking bracket 2 is provided on the roof 1, and the snow-blocking bracket 2 is arranged on the side of the low end 41 of the photovoltaic panel 4. The snow-blocking bracket 2 is specifically a plate-shaped structure and is vertically fixed on the oblique beam 5, and the snow-blocking net 3 is installed on the snow-blocking bracket 2 to prevent snow on the photovoltaic panel 4 from sliding off the eaves.

[0029] The side of the snow guard bracket 2 facing the photovoltaic panel 4 is the mounting side 21 for mounting the snow guard net 3. The mounting side 21 is continuously bent into a stepped shape, and the cross-sectional shape of the snow guard net 3 matches the stepped shape of the mounting side 21. The snow guard net 3 is composed of an upper flat plate 31, a vertical plate 32 and a lower flat plate 33 from top to bottom. Both the upper flat plate 31 and the lower flat plate 33 are perpendicular to the vertical plate 32. The mounting side 21 is composed of an upper flat edge 211, a vertical edge 212 and a lower flat edge 213 from top to bottom. Both the upper flat edge 211 and the lower flat edge 213 are perpendicular to the vertical edge 212. The upper flat edge 31, the vertical plate 32 and the lower flat edge 33 are matched with the upper flat edge 211, the vertical edge 212 and the lower flat edge 213 respectively; the middle part of the vertical plate 32 and the vertical edge 212 is provided with an inclined inclined section, and the inclined section of the vertical edge 212 is provided with a bolt fixing plate 22, and the bolt fixing plate 22 is fixed to the vertical plate 32 by bolts. Specifically, the inclined section of the vertical edge 212 extends laterally to form an inclined bolt fixing plate 22. Taking the installation side 21 as the left side of the snow guard bracket 2 as an example, the bolt fixing plate 22 is formed by extending the inclined section of the vertical edge 212 backward or forward. The bolt fixing plate 22 is perpendicular to the snow guard bracket 2, and the inclined section of the vertical plate 32 is in contact with the bolt fixing plate 22. A bolt mounting hole 221 is provided on the bolt fixing plate 22, and a through hole 321 for the bolt to pass through is correspondingly provided on the vertical plate 32. After the bolt passes through the through hole 321 and the bolt mounting hole 221, it is screwed with a nut to fix the snow guard net 3.

[0030] Key references Figure 6 When the staff installs the snow guard net 3, they only need to place the snow guard net 3 on the installation side 21 of the snow guard bracket 2 from top to bottom, the upper plate 31 will be placed on the upper flat edge 211, and the vertical plate 32 will fit with the vertical edge 212, and the lower plate 33 will be placed on the lower flat edge 213, and the snow guard net 3 can be installed in place. After that, the bolts are installed and locked to complete the installation. The inclined sections in the middle of the bolt fixing plate 22 and the vertical plate 32 are tilted so that the bolt fixing plane (that is, the surface of the bolt fixing plate 22) is not perpendicular to the photovoltaic panel 4, but is set toward the upper left, so that the bolt can be installed at an angle, and the bolt head after installation is tilted upward. This setting is more in line with the staff's operating habits, and the staff can easily find the position of the bolt mounting hole 221 and install the bolt without leaning forward, making the bolt installation easier.

[0031] Key references Figure 5 The mounting side 21 is arranged on the upper part of the snow guard bracket 2, and the snow guard net 3 is higher than the upper surface of the photovoltaic panel 4, so that the snow guard net 3 can block the snow on the photovoltaic panel 4; the edge of the lower flat plate 33 extends downward to provide a lower guard edge 35, and the lower guard edge 35 abuts against the low end 41 of the photovoltaic panel 4 to prevent the accumulated snow from leaking out from between the photovoltaic panel 4 and the snow guard net 3, so as to improve the snow blocking effect.

[0032] As a preferred embodiment, the edge of the upper flat plate 31 is extended upward to provide an upper guard edge 34, and the upper guard edge 34 and the lower guard edge 35 are arranged symmetrically with respect to the center, so that the snow guard net 3 is a symmetrical structure. When installing the snow guard net 3, there is no need to distinguish between the upper and lower parts of the snow guard net 3, making the installation of the snow guard net 3 simpler.

[0033] Key references Figure 4 The cross-section of the inclined beam 5 is U-shaped, and the lower part of the snow guard bracket 2 can be fixed in the U-shaped groove 51 of the inclined beam 5. The snow guard bracket 2 can be fixed to the inclined beam 5 by bolts. A mounting plate 23 is formed by extending laterally (towards the front or rear side) at the lower part of the snow guard bracket 2. The mounting plate 23 is perpendicular to the snow guard bracket 2 and fits with the inclined beam 5. Through holes for bolts to pass through are opened on the mounting plate 23 and the inclined beam 5, and the fixing bolts can be self-clinching bolts.

[0034] Furthermore, an inverted L-shaped card plate 24 is extended laterally from the middle part of the snow guard bracket 2, and the card plate 24 is located above the mounting plate 23. The card plate 24 is engaged with a U-shaped arm of the inclined beam 5, which can increase the stability of the snow guard bracket 2. Moreover, when installing the snow guard bracket 2, first place the lower part of the snow guard bracket 2 into the U-shaped groove 51 of the inclined beam 5, and then engage the card plate 24 with a U-shaped arm of the inclined beam 5, so that the through holes 321 on the mounting plate 23 and the inclined beam 5 can be aligned, making the installation of the snow guard bracket 2 more convenient.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
