Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a light-collecting bracket for increasing power during the installation of a photovoltaic array. Background Art

[0002] In recent years, the new energy industry has developed steadily. Photovoltaic power generation technology, as one of its branches, occupies a relatively important position in the new energy industry. The sun is an energy source with extremely huge energy in nature, and its utilization value is immeasurable. The photovoltaic industry also has great development potential. How to make full use of sunlight has become one of the hot topics in today's photovoltaic industry.

[0003] Photovoltaic power stations, in simple terms, capture sunlight in a certain area through solar cells and convert it into electricity. Today, the main photovoltaic power stations are divided into centralized power stations and distributed power stations, but no matter how they are divided, they will face a problem in installation. In the installation of the array, the photovoltaic modules are fixed to the photovoltaic brackets. Therefore, due to the structure of the photovoltaic brackets and related connectors, there will be a large gap between adjacent photovoltaic modules. In the entire array, the total area of ​​these gaps accounts for a large proportion and is a part that cannot be ignored. The light intensity of this part is often absorbed by the installation site and is not captured by the photovoltaic modules, resulting in energy loss. According to research data, the installation site can absorb about 51% of the solar irradiance, which is undoubtedly a huge energy loss. Therefore, a device is needed to reduce the light intensity of this part projected onto the installation site to improve the efficiency and power generation of the photovoltaic power station. Utility Model Content

[0005] To achieve the above purpose, the solution of the utility model is: a concentrating bracket for increasing power in the installation of a photovoltaic array, which is placed in the gap between two adjacent photovoltaic modules, and the concentrating bracket includes a concentrating bracket body with a U-shaped cross-section, the bottom of the concentrating bracket body is fixed to the photovoltaic bracket by fasteners, and both sides of the U-shaped opening of the concentrating bracket body extend outward to form fixed convex edges, and the photovoltaic module is placed between the photovoltaic bracket and the fixed convex edge of the concentrating bracket body, and the fixed convex edge of the concentrating bracket body and the photovoltaic bracket are clamped on the upper and lower surfaces of the photovoltaic module by adjusting the fasteners;

[0006] The top of the fixed protrusion is provided with a mirror layer which is inclined downward from the inside to the outside, and the light is reflected onto the photovoltaic module through the mirror layer.

[0007] Furthermore, the angle between the mirror layer and the horizontal plane is 45°.

[0008] Furthermore, the middle portion of the focusing bracket body is a water guide groove.

[0009] Furthermore, the bottom of the fixed protrusion is a contact surface parallel to the surface of the photovoltaic module.

[0010] Furthermore, a sawtooth pattern is formed on the contact surface between the bottom of the fixed protrusion and the photovoltaic module.

[0011] Furthermore, the bottom of the focusing bracket body is fixed to the photovoltaic bracket by means of threaded connection.

[0012] Furthermore, a plurality of bolt holes are provided at the bottom of the focusing bracket body, and bolt connecting holes are provided at positions corresponding to the bolt holes of the photovoltaic bracket.

At the same time, the shape design of the top of the device can be used as a water channel to discharge rainwater to the ground;

[0018] The U-shaped focusing bracket can also fill the gaps, making the overall appearance of the array more complete and consistent with the application scenario. In the environment of distributed power stations, the setting of the mirror layer also increases the integrity and appearance of the array.

[0019] The contact surface between the focusing bracket and the photovoltaic module is also provided with a serrated pattern to increase the relative roughness of the contact surface, thereby increasing the static friction between the focusing bracket and the photovoltaic module, fixing it and preventing slipping.

[0020] The concentrating bracket of the utility model can replace conventional pressing blocks to fix the photovoltaic components and the photovoltaic bracket, which greatly reduces the use of pressing blocks and the costs caused by them; from the perspective of improving efficiency, the concentrating bracket integrates fixing and focusing, which improves the installation efficiency of the system to a certain extent.

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

[0028] The utility model provides a focusing bracket for increasing power in photovoltaic array installation, such as Figures 1 to 3 As shown, it is used to fix two adjacent photovoltaic modules 3 and the photovoltaic bracket 4. The focusing bracket is placed in the gap between the two adjacent photovoltaic modules 3 and can fill the gap between the two adjacent photovoltaic modules 3.

[0029] like Figure 1 As shown, the concentrator bracket includes a concentrator bracket main body 1 with a U-shaped cross-section, the bottom of the concentrator bracket main body 1 is fixed to the photovoltaic bracket 4 by fasteners, and the two sides of the U-shaped opening of the concentrator bracket main body 1 extend outward to form fixed flanges 2, and the photovoltaic component 3 is placed between the photovoltaic bracket 4 and the fixed flange 2 of the concentrator bracket main body 1. By adjusting the fasteners, the fixed flange 2 of the concentrator bracket main body 1 and the photovoltaic bracket 4 are respectively clamped on the upper and lower surfaces of the photovoltaic component 3, thereby fixing the photovoltaic component 3.

[0030] The focusing bracket can completely cover the gaps between adjacent photovoltaic modules 3 in the array, preventing rainwater from leaking from the gaps to the ground and soaking the connecting terminals, DC cables and other power components on the ground, effectively reducing the possibility of grounding on rainy days and improving the safety of maintenance on rainy days to a certain extent. At the same time, the middle part of the focusing bracket body 1 can be used as a water guide 11 to discharge the accumulated water to the ground.

[0031] As a further improvement of the structure, Figure 1 As shown, the top of the fixed flange 2 has a slope sloping downward from the inside to the outside, and the surface of the slope is mirror-polished to form a downward-sloping mirror layer 21. The mirror layer 21 has good reflectivity, and light is reflected by the mirror layer 21 onto the photovoltaic module 3, thereby achieving the effect of increasing the power generation power of the photovoltaic module 3.

[0032] The angle between the mirror layer 21 and the horizontal plane is preferably designed to be 45° in order to better reflect light. Figure 3 As shown, when light is incident vertically on the mirror layer 21, it will be reflected to the surface of the photovoltaic component 3 on the same side, thereby improving the power generation efficiency; if the mirror layer 21 is not provided, the light there cannot be captured by the photovoltaic component 3, resulting in energy loss.

[0033] Key References Figure 1 The bottom of the fixed convex edge 2 is a contact surface parallel to the surface of the photovoltaic module 3, and a serrated pattern 22 is formed on the contact surface. When the photovoltaic bracket 4 is fixed to the concentrating bracket, the compression force generated by the connection of the fasteners such as the bolts 5 will cause the two sides of the concentrating bracket to generate compression force on the photovoltaic module 3. The serrated pattern 22 on the contact surface can effectively increase the relative roughness of the contact surface, thereby increasing the static friction between the concentrating bracket and the photovoltaic module 3, making it fixed and preventing the occurrence of slipping.

[0034] The bottom of the focusing bracket body 1 is fixed to the photovoltaic bracket 4 by threaded connection. Figure 2 and Figure 3 As shown, the bottom of the concentrator bracket body 1 is provided with a plurality of bolt holes 12, and the photovoltaic bracket 4 is provided with bolt connection holes 41 at positions corresponding to the bolt holes 12. The bolts 5 pass through the bolt holes 12 and the bolt connection holes 41 from the inner side of the concentrator bracket body 1 in sequence to reach the outer side of the photovoltaic bracket 4, and are tightened by nuts 6, thereby fixing the concentrator bracket body 1 to the photovoltaic bracket 4. This case does not limit the position and number of the bolt holes 12 on the concentrator bracket, and can be arranged according to the size of the actual photovoltaic module 3 and the position of the photovoltaic bracket 4.

[0035] The design of the bolt hole 12 at the bottom of the focusing bracket also takes into account the requirements of waterproofing and drainage. Figure 1As shown, the side wall of the bolt hole 12 extends axially upward to form a bolt seat 13 with a "convex" cross-section, and the bottom of the bolt 5 head abuts against the top of the "convex" bolt seat 13. The bolt seat 13 is designed to be "convex" to prevent water or snow from eroding the bolt 5, thereby improving the life cycle of the device.

[0036] The method of using the utility model focusing bracket is as follows (refer to Figure 3 ):

[0037] First, pre-connect the focusing bracket with the photovoltaic bracket 4 by means of bolts 5, then place the photovoltaic assembly 3 on the photovoltaic bracket 4, and adjust the position of the photovoltaic assembly 3 so that it is located at the desired installation position, and then adjust the bolts 5 and nuts 6 so that the fixed flange 2 presses the photovoltaic assembly 3 onto the photovoltaic assembly 3, thereby completing the assembly of the photovoltaic assembly 3.

[0038] After installation, the focusing bracket fills the gaps in the arrangement of conventional photovoltaic modules 3. On the one hand, the focusing bracket makes the photovoltaic modules 3 array more beautiful. On the other hand, due to the focusing effect of the mirror layer 21, the light intensity that cannot be captured by the photovoltaic modules 3 can be reflected on the photovoltaic modules 3, thereby improving the power generation of the photovoltaic modules 3. In some severe weather, the focusing bracket can also play a certain protective role in the photovoltaic system. For example, in rainy weather, it can prevent rainwater from leaking on the ground, causing grounding faults in rainy days, and can also protect the terminal from water damage to a certain extent. In addition, the "convex" structure of the bolt seat 13 can also effectively prevent the erosion of the bolt 5 connection by accumulated water or snow, thereby improving the life cycle of the device.
