Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic panel frame and a photovoltaic component. Background Art

[0002] Photovoltaic modules are devices that can convert solar energy into electrical energy and are widely used. The surface of existing photovoltaic modules is relatively flat and smooth, and is mainly used in areas with good lighting conditions, no freezing rain, and no ice and snow disasters. However, when extreme weather such as freezing rain, ice and snow occur, a thin layer of ice will form on the surface of the photovoltaic module due to the low temperature, and the thin ice will be covered with a thicker layer of snow or ice. When the temperature rises, the thin ice will gradually melt. Since the surface of the photovoltaic module is flat and smooth, the ice layer on the surface of the photovoltaic module or the snow layer on the ice layer will freeze and thaw suddenly. When a large area of ​​ice and snow falls suddenly, it has a large instantaneous impact load, which is very easy to cause damage to houses, vehicles and pedestrians. Utility Model Content

The first connecting plate and the baffle will block the ice and snow layer to prevent the ice and snow layer from falling suddenly due to gravity. At the same time, the hook formed at one end of the baffle increases the contact area with the ice and snow layer, so that the snow-blocking assembly forms a firm connection with the ice and snow layer, further enhancing the blocking effect of the snow-blocking assembly on the ice and snow layer, and effectively avoiding the problem of sudden falling of the ice and snow layer.

[0014] In an optional embodiment, the snap-in plate is provided with a third receiving groove, the third receiving groove is communicated with the first slot, and when the photovoltaic panel is inserted into the first slot, the third receiving groove is suitable for filling with adhesive material.

[0034] When encountering extreme weather such as snowing, freezing rain, etc., a layer of ice and snow will form on the surface of the photovoltaic panel inserted in the first slot 111, and the edge of the ice and snow layer will spread into the first accommodating groove 23 formed by the support component 1, the first connecting plate 21 and the baffle 22. The first connecting plate 21 and the baffle 22 will block the ice and snow layer to prevent the ice and snow layer from falling suddenly due to gravity. At the same time, the hook portion 221 formed at one end of the baffle 22 increases the contact area with the ice and snow layer, so that the snow-blocking component 2 forms a firm connection with the ice and snow layer, further strengthening the blocking effect of the snow-blocking component 2 on the ice and snow layer, and effectively avoiding the problem of sudden falling of the ice and snow layer.

[0035] Specifically, the support assembly 1 includes a plug-in portion 11, which includes a first support plate 112, a second connection plate 113 and a snap-in plate 114, the first connection plate 21 is connected to the snap-in plate 114, one end of the second connection plate 113 is connected to one end of the snap-in plate 114, and the other end of the second connection plate 113 is connected to the first support plate 112, a first slot 111 is formed between the first support plate 112, the second connection plate 113 and the snap-in plate 114, and a first accommodating groove 23 is formed between the snap-in plate 114, the first connection plate 21 and the baffle 22. The first slot 111 is formed between the first support plate 112, the second connection plate 113 and the snap-in plate 114, so that the photovoltaic panel can be inserted into the first slot 111 and connected to the support assembly 1.

[0036] Specifically, the clamping plate 114 is provided with a third accommodating groove 1141, which is connected to the first slot 111. When the photovoltaic panel is inserted into the first slot 111, the third accommodating groove 1141 is suitable for filling with adhesive material.

[0037] Specifically, the support assembly 1 further includes a heat preservation portion 12, which is disposed at the lower end of the plug-in portion 11. The heat preservation portion 12 is provided with a fourth accommodating cavity 123, and the fourth accommodating cavity 123 is suitable for filling with heat preservation material. The heat preservation material filled in the fourth accommodating cavity 123 can play a role in heat preservation and heat insulation, and can extend the service life of the photovoltaic panel while also enhancing the power generation efficiency.
