Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic power station construction equipment, and particularly relates to an anti-skid snow device for photovoltaic modules. Background Art

[0002] In the application of the slope roof structure of distributed power stations, the inclination angle of photovoltaic modules is too large, and large ice blocks are easily formed during the freezing and thawing of snow in winter, which can easily cause safety and property loss incidents. In order to reduce the harm caused by snow sliding, it is necessary to install a snow blocking device on the row of modules at the lowest position of the photovoltaic array, so as to divide the large-area sliding snow into small pieces of snow. However, the existing snow blocking devices cannot adapt to photovoltaic panels without frames at the short side parts during installation, or need to drill holes in the frames of the photovoltaic panels, which will damage the modules.

[0003] There is a publicly known snow blocking device for photovoltaic modules (patent application number: CN202222406439.7), which includes a U-shaped clamping part for clamping on the long side of the photovoltaic module. The U-shaped clamping part includes an upper clamping plate, a connecting surface and a lower clamping plate connected in sequence. Through holes for passing through fasteners to fasten the U-shaped clamping part to the long side of the photovoltaic module are formed on the surface of the lower clamping plate, and a snow blocking plate is connected to one side of the lower clamping plate.

[0004] This disclosed solution can be used for photovoltaic modules without frames at the bottom of the short side, and can divide the snow on the basis of not damaging the module frame and avoiding hidden cracks in the module. However, it can only be installed at the corner positions, and the installation area is limited. It cannot perform segmentation processing on the skiing in the middle of the photovoltaic module, and there are technical defects. Moreover, it is clamped and installed on the side of the photovoltaic module through fasteners, and the fasteners are structures similar to screws. During the fastening process, it will still damage the photovoltaic module, and it is easy to loosen during long-term use, and the fastening effect is not good. Summary of the Utility Model

[0005] The present application provides an anti-skid snow device for photovoltaic modules, aiming to solve the problems that the above-mentioned snow blocking device can only be installed at the corner positions, the installation area is limited, the skiing in the middle of the photovoltaic module cannot be segmented, and during the fastening process, it will damage the photovoltaic module, and it is easy to loosen during long-term use, and the fastening effect is not good.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An anti-skid snow device for a photovoltaic module, comprising a fixture and a snow dividing member. The snow dividing member is installed on the back of the fixture away from the photovoltaic module. A clamping adjustment assembly is installed on the lower clamping plate of the fixture. The clamping adjustment assembly includes a rotary knob, a screw rod and a clamping plate. One end of the screw rod is fixed to the rotary knob, and the other end of the screw rod passes through the lower clamping plate and is fixed to the clamping plate. The side of the photovoltaic module is located between the clamping plate and the upper clamping plate of the fixture, and the snow dividing member is slidably connected to the back of the fixture.

Detailed implementation mode

[0023] Embodiment 1

[0024] As Figures 1-3 shown, an anti-skiing device for a photovoltaic module includes a clamp 1 and a snow separating member 2. The snow separating member 2 is installed on the back of the clamp 1 away from the photovoltaic module. The lower clamping plate 11 of the clamp 1 is provided with a clamping and adjusting assembly 3. The clamping and adjusting assembly 3 includes a knob 31, a screw rod 32 and a clamping plate 33. One end of the screw rod 32 is fixed to the knob 31, and the other end of the screw rod 32 passes through the lower clamping plate 11 and is fixed to the clamping plate 33. The side of the photovoltaic module is located between the clamping plate 33 and the upper clamping plate 13 of the clamp 1. The snow separating member 2 is slidably connected to the back of the clamp 1.

[0025] The snow separating member 2 is vertically arranged, so that like a blade, the snow sliding down on the photovoltaic module is divided into small pieces and falls, avoiding potential safety risks.

[0026] The connecting panel 12 of the clamp 1 is provided with a slide rail 121. The snow separating member 2 includes a slider 21 and a snow separating plate 22 for separating skiing. The snow separating plate 22 is fixed to the slider 21, and the slider 21 is slidably connected to the slide rail 121.

[0027] After the clamp 1 is clamped and installed, if it is necessary to finely adjust the position of the snow separating member 2, it can be achieved by sliding the slider 21, without the need to remove and reinstall the clamp 1 again, which is more convenient to use.

[0028] One end of the snow separating plate 22 close to the upper clamping plate 13 is provided with a snow blocking member.

[0029] The snow blocking member is an arc-shaped baffle 23, and the arc-shaped baffle 23 is located in the middle or at the tail of one end of the snow separating plate 22 close to the upper clamping plate 13.

[0030] The arc-shaped baffle 23 assists the snow dividing plate 22 in dividing the accumulated snow.

[0031] The end face of the snow dividing member 2 close to the upper clamping plate 13 is not in the same plane as the upper clamping plate 13.

[0032] There is an included angle between the snow dividing member 2 and the fixture 1, so as to ensure that when the accumulated snow slides down, it can be divided by the snow dividing member 2 instead of continuing to slide along the snow dividing member 2.

[0033] The orthographic projection of the clamping plate 33 in the direction of the lower clamping plate 11 is located within the lower clamping plate 11.

[0034] The working principle of this device: First, adjust the clamping plate 33 to one side of the lower clamping plate 11, then install it on the side edge of the photovoltaic module, and then rotate the knob 31 from below to gradually bring the clamping plate 33 closer to the upper clamping plate 13 until it is locked and fixed to the side edge of the photovoltaic module to complete the connection.

[0035] Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that: as Figure 4 shown, the snow blocking member is an arc-shaped convex block 24, and the arc-shaped convex block 24 is located in the middle or at the tail of the end of the snow dividing plate 22 close to the upper clamping plate 13.

[0037] The shape and structure of the snow blocking member are diverse, as long as it can assist the snow dividing plate 22 in dividing the accumulated snow.

[0038] Embodiment 3

[0039] The difference between this embodiment and Embodiment 1 is that: the upper clamping plate 13 is provided with a plurality of first rubber pads 131, and the clamping plate 33 is provided with a plurality of second rubber pads 331.

[0040] The first rubber pads 131 and the second rubber pads 331 play a role in preventing damage during contact and increasing the clamping effect.

[0041] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
