[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a guide-rail photovoltaic module. Background Art

Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (assemblies), controllers and inverters, and the main components are composed of electronic components.

[0003] Since photovoltaic power generation requires laying a large number of photovoltaic panels to collect sunlight, a large amount of land area is required in the process of building photovoltaic power plants. In order to prevent the occupation of a large amount of arable land, photovoltaic power plants are now mostly built in Gobi and desert areas. However, in the prior art, photovoltaic modules will experience high temperatures when working in the Gobi and desert, which will affect the working efficiency of the photovoltaic panels. In addition, strong wind and sand will cause destructive problems such as scratches and marks on the surface of the photovoltaic panels, thereby affecting the power generation efficiency of the photovoltaic panels. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a guide-rail photovoltaic assembly.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a guide rail photovoltaic assembly, comprising a bracket, a guide rail arranged in parallel is fixedly installed on the upper end of the bracket, a shell is detachably installed on the guide rail, a heat absorbing plate is fixedly installed between the inner walls of the left and right sides of the shell, a plurality of photovoltaic panels are installed on the front of the heat absorbing plate, and the front of the plurality of photovoltaic panels is jointly covered with a four-layer glass assembly, the four-layer glass assembly is fixedly connected to the shell, and the four-layer glass assembly includes an outer layer of glass, a left inlaid glass, a right inlaid glass and an inner layer of glass, there is a gap between every two layers of glass, the outer layer of glass is a convex curved surface shape, the left inlaid glass and the right inlaid glass are staggered with each other, and both are concave curved glass, and the inner layer of glass is a flat glass;

[0006] A fixed shell distributed laterally is fixedly mounted on the upper end of the heat absorbing plate, an air intake assembly is mounted on the fixed shell, and an output end of the air intake assembly faces the four-layer glass assembly;

[0007] A plurality of second air outlets are provided at the lower end of the shell, and the plurality of second air outlets are all connected with the gaps inside the four-layer glass assembly.

[0008] Preferably, a fixing piece is slidably mounted on the guide rail, a plurality of threaded holes are provided at equal intervals on the bottom wall of the guide rail, and both sides of the housing are fixedly connected to the fixing piece.

[0009] Preferably, the heat absorption plate is made of a composite phase change material, and a plurality of rectangular grids are evenly distributed on the front side thereof, and the photovoltaic panel is embedded and installed inside the rectangular grids.

[0010] Preferably, microcrystals are evenly distributed on the concave surfaces of the left inlaid glass and the right inlaid glass.

[0011] Preferably, the microcrystals are in the shape of small protrusions and are made of glass.

[0012] Preferably, the air intake assembly includes a plurality of groups of suction fans fixedly mounted on the lower surface of a fixed shell, a filter is detachably mounted at the air inlet of the suction fan, a first air outlet is fixedly connected to a side of the fixed shell facing the heat absorption plate, and the first air outlet is directed toward the four-layer glass assembly at an end away from the fixed shell.

[0013] Preferably, the second filter screen and the first filter screen are fixedly installed in the fixed shell from bottom to top.

[0014] Preferably, a third filter is detachably installed inside the second air outlet.

[0015] Preferably, a plurality of heat dissipation holes are provided inside the heat absorbing plate, and the heat dissipation holes are used to enhance the heat dissipation of the heat absorbing plate.

[0016] Preferably, a base is fixedly mounted on the lower end of the bracket.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. In the present application, a four-layer glass assembly is arranged, and the outer layer of glass is a convex curved surface shape. On the one hand, it can make the flow of external air on the glass surface smoother, reducing air stagnation and heat accumulation. On the other hand, it can increase the area of ​​illumination and increase its light reception. The left embedded glass and the right embedded glass are both concave curved glass. The staggered glass structure increases the complexity of the air layer, prolongs the heat conduction path, and reduces the convective heat exchange in the air layer. At the same time, the concave design can make the surface area of ​​the glass relatively small, and the loss of light in the propagation process is relatively small. Therefore, the concave glass has a relatively high degree of absorption of light.

[0019] 2. In the present application, microcrystals are evenly distributed on the concave surfaces of the left embedded glass and the right embedded glass. The microcrystals can make the incident light reflect and refract multiple times between the microstructures, increase the absorption path of light, and improve the utilization rate of light energy.

[0020] 3. In the present application, by configuring the heat absorbing plate, the fixed shell, the first filter and the second filter, on the one hand, the heat absorbing plate can fully absorb the heat on the photovoltaic panel and dissipate the heat, and on the other hand, the suction fan will inhale air and filter the sand and dust inside through the double-layer filter, so that the air is blown out from the first air outlet and enters the four-layer glass assembly. According to the principle that hot air rises and cold air falls, the downward blowing of the wind will cause the rising hot air inside to form natural convection, thereby accelerating the cooling of the inside of the glass.

[0021] In summary, the present application optimizes and improves the light energy conversion of photovoltaic modules in the desert through the setting of the above-mentioned structure, so that when the wind and sand are strong and the temperature is high in the desert, the photovoltaic modules can be protected and cooled, thereby preventing the temperature of the photovoltaic modules from being high, thereby improving the working efficiency of the photovoltaic modules and making the photovoltaic modules generate more electricity.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1 to 12 A guide rail photovoltaic module includes a base 1, a bracket 2 is fixedly installed on the upper end of the base 1, two sets of guide rails 3 arranged in parallel are fixedly installed on the upper end of the bracket 2, a fixing member 5 is slidably installed on the guide rail 3, and a plurality of threaded holes 4 are evenly spaced on the bottom wall of the guide rail 3. After the fixing member 5 is placed on the guide rail 3, bolts can be screwed into the threaded holes 4 to fix the fixing member 5 on the guide rail 3. A shell 6 is placed above the guide rail 3, and both sides of the shell 6 are fixedly connected to the fixing member 5, so that the shell 6 can be fixed to the guide rail 3 through the fixing member 5.

[0037] A heat absorbing plate 7 is fixedly installed between the inner walls on the left and right sides of the shell 6. A plurality of rectangular grids are evenly distributed on the front of the heat absorbing plate 7. A photovoltaic panel 9 is embedded and installed inside each rectangular grid. The front of the plurality of photovoltaic panels 9 is jointly covered with a four-layer glass assembly. The four-layer glass assembly is fixedly connected to the shell 6. The four-layer glass assembly includes an outer layer of glass 15, a left embedded glass 16, a right embedded glass 17 and an inner layer of glass 18 (as shown in the attached manual). Figures 11 to 12 As shown), there is a gap between each two layers of glass to facilitate air flow. The outer layer of glass 15 is a convex curved surface (i.e., the side facing the sun). The convex shape can make the flow of external air on the glass surface smoother, reducing air stagnation and heat accumulation. On the other hand, it can increase the area of ​​light and increase its light reception.

[0038] The left inlaid glass 16 and the right inlaid glass 17 are arranged in a staggered manner (see the attached manual). Fig.11 As shown in the figure, there is a gap for air flow at one end of the two adjacent to each other, and the left embedded glass 16 and the right embedded glass 17 are both concave curved glass. The staggered glass structure increases the complexity of the air layer, prolongs the path of heat conduction, and reduces the convective heat exchange in the air layer. At the same time, the concave design can make the surface area of ​​the glass relatively small, and the loss of light during the propagation process is relatively small. Therefore, the concave glass has a relatively high degree of absorption of light. Microcrystals 19 are evenly distributed on the concave surfaces of the left embedded glass 16 and the right embedded glass 17. The microcrystals 19 are in the shape of small protrusions and are made of glass. By setting the microcrystals 19, the incident light can be reflected and refracted multiple times between the microstructures, increasing the absorption path of light and improving the utilization rate of light energy.

[0039] The inner glass 18 is a flat glass, which forms a double-layer glass structure with the outer glass 15 . The double-layer glass structure can reduce reflection damage and increase the light absorption rate of the photovoltaic panel 9 .

[0040] A fixed shell 10 distributed laterally is fixedly installed on the upper end of the heat absorbing plate 7, and a plurality of suction fans 13 are fixedly installed at equal intervals on the lower surface of the fixed shell 10. A filter screen (not shown in the figure) is detachably installed at the air inlet of the suction fan 13. A second filter screen 12 and a first filter screen 11 are fixedly installed in the fixed shell 10 from bottom to top in sequence. By arranging the filter screen, the second filter screen 12 and the first filter screen 11, the air sucked into the fixed shell 10 through the suction fan 13 can be fully filtered, thereby ensuring the purity of the gas. A first air outlet 14 is fixedly connected to the side of the fixed shell 10 facing the heat absorbing plate 7. The end of the first air outlet 14 away from the fixed shell 10 faces the four-layer glass component, so that the purified air can be blown into the gap between the four-layer glass components. A plurality of second air outlets 20 are equidistantly provided at the lower end of the outer shell 6. The plurality of second air outlets 20 are all connected to the gap inside the four-layer glass component, and a third filter screen 21 is detachably installed inside the second air outlet 20.

[0041] A plurality of heat dissipation holes 8 are provided inside the heat absorbing plate 7 to enhance the heat dissipation of the heat absorbing plate 7 .

[0042] The specific working principle of the present invention is as follows: first, the fixing member 5 and the shell 6 are threadedly connected so that the four fixing members 5 are fixed on the shell 6, and then the fixing member 5 is placed obliquely on the guide rail 3, the base 1 and the bracket 2 are fixedly connected, the bracket 2 and the guide rail 3 are fixedly connected, and a plurality of groups of threaded holes 4 are provided on the guide rail 3, and then the fixing member 5 and the threaded holes 4 are fixedly connected so that they are fixed on the guide rail 3, thereby fixing the entire device.

[0043] The temperature in the desert is high during the day, and the high temperature will increase the series resistance of the photovoltaic module by about 20% to 30%, which will directly affect the power generation efficiency of the photovoltaic module. It will also affect the bypass diode. If the bypass diode has poor heat dissipation, it may cause its temperature to be too high and damaged, thereby affecting the performance and safety of the entire photovoltaic module. Therefore, the photovoltaic panel 9 of the device is installed on the heat absorbing plate 7, and the outer surface of the heat absorbing plate 7 and the outer shell 6 are fixedly connected. The photovoltaic panel 9 is embedded in the inside of the heat absorbing plate 7. The material of the heat absorbing plate 7 is a composite phase change material, so that it can absorb the heat from the photovoltaic panel 9, and the heat absorbing plate 7 is provided with a heat dissipation hole 8, and the heat dissipation hole 8 is on the shady side, which can enable it to have a certain heat dissipation effect in the desert.

[0044] A fixed shell 10 is fixedly connected to one side surface of the heat absorbing plate 7, and a first filter 11 is arranged on one side of the interior of the fixed shell 10, and a second filter 12 is arranged on one side of the first filter 11, and a suction fan 13 is arranged inside the fixed shell 10, and an outer layer of glass 15, a left embedded glass 16, a right embedded glass 17 and an inner layer of glass 18 are fixedly connected to the inner side of the outer shell 6, a second air outlet 20 is opened on one side surface of the outer shell 6, and a third filter 21 is arranged on the outer side surface of the second air outlet 20. When the device is working, the suction fan 13 will inhale air, and filter the internal sand and dust through the double-layer filter, so that the air is blown out of the first air outlet 14.

[0045] The outer layer of glass 15 and the inner layer of glass 18 form a double-layer glass structure, which can reduce reflection damage and increase the light absorption rate of the photovoltaic panel 9. The outer layer of glass 15 is convex in shape, so that the convex surface allows the external air to flow more smoothly on the glass surface, reduces air stagnation and heat accumulation, and increases the area of ​​illumination, increasing its light reception. The inner left embedded glass 16 and the right embedded glass 17 are staggered designs, and both pieces of glass are concave curved glass. The staggered glass structure increases the complexity of the air layer, lengthens the heat conduction path, and reduces the convective heat exchange in the air layer.

[0046] When two pieces of glass are staggered, the flow of air is restricted, reducing the possibility of heat transfer through convection. At the same time, the concave design can make the surface area of ​​​​the glass relatively small, and the loss of light during the propagation process is relatively small. Therefore, the concave glass absorbs light to a relatively high degree.

[0047] Microcrystals 19 are arranged on the concave surfaces of the left embedded glass 16 and the right embedded glass 17. The microcrystals 19 are shaped like small protrusions, which can make the incident light reflect and refract multiple times between the microstructures, increase the light absorption path, and improve the utilization rate of light energy. The conduction temperature on the inner side of the glass after long-term exposure to the sun will be too high, which will cause a certain impact on the photovoltaic panel. The structure of the four-layer glass component can increase the thermal resistance to the greatest extent, so that the wind can take away heat faster when blowing from top to bottom. The second air outlet 20 and the third filter 21 at the bottom can block the wind and sand and prevent it from entering the inside of the glass. According to the principle that hot air rises and cold air falls, the downward blowing of the wind will cause the rising hot air inside to form natural convection, thereby accelerating the cooling of the inside of the glass.

[0048] The characteristic of the composite phase change material is that it can store heat. When the desert turns to night, the composite phase change material will release heat, giving the photovoltaic panel 9 a certain amount of heat, so that it can be protected to a certain extent, increase its service life, and prevent its output power from fluctuating greatly when the sun rises in the early morning of the next day. The double-layer glass in this device is LOW-E double-layer glass, and the embedded glass is ultra-white glass.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
