[0039] See also Figure 1 and Figure 4 , Figure 1 A schematic diagram of a photovoltaic assembly installation frame provided in some embodiments of the present application is shown. Figure 4 Schematic diagrams of photovoltaic assembly installation frames provided in other embodiments of the present application are shown.
[0040] The photovoltaic module installation frame provided in an embodiment of the present application includes a first installation frame 100 and a second installation frame 200. A first installation cavity 110 is configured on one side of the first installation frame 100, and the first installation cavity 110 is used to install a first photovoltaic module. A first clamping groove 120 is configured on the side of the first installation frame 100 away from the first installation cavity 110; the second installation frame 200 and the first installation frame 100 are arranged along a first direction and are clamped and connected to each other. Specifically, the first direction is Figures 1-5xx' direction in the second mounting frame 200; a second mounting cavity 210 is configured on one side of the second mounting frame 200, and the second mounting cavity 210 is used to install a second photovoltaic module. A guide portion 220 extending along a second direction is configured on one side of the second mounting frame 200 away from the second mounting cavity 210, and the second direction is set at an angle to the first direction. Specifically, the second direction is Figures 1-5 In the yy′ direction, the guide portion 220 can extend into the first clamping groove 120.
[0041] When two photovoltaic modules adjacent to each other are installed by the photovoltaic module installation frame provided by the present application, a guide portion 220 extending along the second direction is configured on the side of the second installation frame 200 away from the second installation cavity 210, and the guide portion 220 can extend into the first clamping groove 120. In this way, when the photovoltaic module is in use, the water vapor entering the first clamping groove 120 can flow along the extension direction of the guide portion 220 itself and converge to the bottom of the first clamping groove 120 under the effect of the Coanda effect, reducing the possibility of water vapor flowing in the first clamping groove 120 and penetrating into the cell of the photovoltaic module, making it less likely that the cell of the photovoltaic module will fail due to water ingress, and the service life of the photovoltaic module will be longer.
[0042] The following is a detailed description of the structure of the photovoltaic module installation frame. Figures 2-3 and Figure 5 . Figure 2 Shows Figure 1 FIG. 1 is a schematic diagram of a first mounting frame 100 in a photovoltaic assembly mounting frame. Figure 3 Shows Figure 1 FIG. 1 is a schematic diagram of a second mounting frame 200 in a photovoltaic assembly mounting frame. Figure 5 Shows Figure 4 FIG. 1 is a schematic diagram of a second mounting frame 200 in a photovoltaic assembly mounting frame.
[0043] See also Figure 1 and Figure 3 In some embodiments, a guide tip 221 is configured at the end of the guide portion 220 facing the first clamping groove 120. By providing the guide tip 221, when water vapor flows along the extension direction of the guide portion 220 itself, it can easily drip to the bottom of the first clamping groove 120 through the guide tip 221, thereby reducing the possibility of water vapor flowing in the first clamping groove 120 and penetrating into the solar cell of the photovoltaic module.
[0044] See also Figure 4 and Figure 5, in some embodiments, the end of the diversion part 220 facing the first clamping groove 120 is configured with two diversion plates 222 that are connected to each other and arranged at an angle. By providing the two diversion plates 222, when the first mounting frame 100 is clamped and installed with the second mounting frame 200, the end of the diversion part 220 is not likely to cause injury to people. At the same time, by providing the two diversion plates 222, a groove is formed between the two diversion plates 222. Furthermore, through the converging effect of the groove, the continuous infiltration of water vapor can be blocked.
[0045] Please refer to Figure 5 , in some embodiments, the diversion plate 222 includes an inclined plate 2221 and a vertical plate 2222 that are connected to each other; the inclined plate 2221 is inclined downward from the side of the second mounting frame 200 facing the first mounting frame 100, or inclined downward from the side of the first mounting frame 100 facing the second mounting frame 200; the vertical plate 2222 extends along the second direction. By setting the diversion plate 222 as the inclined plate 2221 and the vertical plate 2222 that are connected to each other, the water droplets formed by the convergence of water vapor are guided through the inclination of the inclined plate 2221, and finally the flow direction of the water droplets is changed by the vertical plate 2222, so that the water droplets are easily dripped to the bottom of the first clamping groove 120 under the action of gravity.
[0046] Please refer to Figure 1 , Figure 2 and Figure 4 , in some embodiments, the first mounting frame 100 includes a first frame body 130 and a first convex arm 140 that is connected to the first frame body 130 and extends along the first direction; the first mounting frame 100 further includes a second convex arm 150 and a third convex arm 160; the second convex arm 150 and the first convex arm 140 are arranged at intervals along the second direction, and the second convex arm 150 extends along the first direction, and one end of the second convex arm 150 is connected to the first frame body 130; the third convex arm 160 extends along the second direction, the third convex arm 160 is connected to the side of the second convex arm 150 away from the first frame body 130, and the third convex arm 160 is arranged facing the side close to the diversion part 220; the first frame body 130, the first convex arm 140, the second convex arm 150, and the third convex arm 160 jointly enclose and form the first clamping groove 120. By setting it in this way, the processing of the first mounting frame 100 is relatively simple and convenient, and the processing cost is relatively low.
[0047] Please refer to Figure 3 and Figure 5, in some embodiments, the second mounting frame 200 includes a second frame body 230 and a fourth convex arm 240 connected to the second frame body 230 and extending in the first direction; the diversion portion 220 is connected to the fourth convex arm 240, and the diversion portion 220 and the fourth convex arm 240 together enclose a second clamping groove 250; when the first mounting frame 100 is clamped and connected to the second mounting frame 200 (specifically, Figure 1 and Figure 4 the state in is the clamped connection state); the first convex arm 140 is received in the second clamping groove 250. By receiving the first convex arm 140 in the second clamping groove 250 in the connected state, the first convex arm 140 can be limited by the groove wall of the second clamping groove 250, so that the splicing gap between the first mounting frame 100 and the second mounting frame 200 after connection is smaller, reducing the possibility of water vapor entering the first clamping groove 120.
[0048] Please refer to Figure 3 and Figure 5 , in some embodiments, the second mounting frame 200 further includes a fifth convex arm 260 and a sixth convex arm 270 that are connected to each other and arranged at an angle; the fifth convex arm 260 and the fourth convex arm 240 are spaced apart in the second direction, and the fifth convex arm 260 extends in the first direction, and one end of the fifth convex arm 260 is connected to the second frame body 230; the sixth convex arm 270 extends in the second direction; the second frame body 230, the fifth convex arm 260, and the sixth convex arm 270 together enclose a third clamping groove 280; when the first mounting frame 100 is clamped and connected to the second mounting frame 200, the third convex arm 160 is clamped in the third clamping groove 280. By setting it like this, the processing of the second mounting frame 200 is relatively simple and convenient, and the processing cost is relatively low. At the same time, in the clamped connection state, due to the limiting effect of the groove wall of the third clamping groove 280 on the third convex arm 160, the splicing gap between the first mounting frame 100 and the second mounting frame 200 after connection is smaller, reducing the possibility of water vapor entering the first clamping groove 120.
[0049] Please refer to Figure 1 and Figure 4 , in some embodiments, both side surfaces of the third convex arm 160 opposite to the sixth convex arm 270 are partially annular structures. By setting it like this, it is more convenient to clamp or separate the third convex arm 160 and the sixth convex arm 270, and thus it is convenient to disassemble and replace the photovoltaic modules with each other.
[0050] In this application, through the cooperation of the first convex arm 140 and the first clamping groove 120, as well as the cooperation of the third convex arm 160 and the sixth convex arm 270, when the first mounting frame 100 and the second mounting frame 200 are in a connected state, the interval in the first direction is relatively reasonable, neither too large nor too small. This makes it easier to engage and connect the first mounting frame 100 and the second mounting frame 200, and at the same time, water vapor is not likely to enter the first clamping groove 120.
[0051] Please refer to Figure 1 and Figure 4 In some embodiments, along the second direction, the end of the diversion portion 220 facing the first clamping groove 120 is disposed below the fifth convex arm 260. By setting it in this way, the length of the diversion portion 220 along the second direction is relatively long, so that the water vapor in the first clamping groove 120 has a larger contact area with the diversion portion 220, and the water vapor is more likely to converge into water droplets on the surface of the diversion portion 220, further reducing the content of water vapor in the first clamping groove 120.
[0052] Please refer to Figure 2 In some embodiments, the end of the first convex arm 140 away from the first frame body 130 protrudes with a clamping protrusion 141 along the second direction. By providing the clamping protrusion 141, when the first convex arm 140 is clamped with the second clamping groove 250, it is not easy to hurt the hand and is relatively safe. At the same time, through the guiding action of the clamping protrusion 141, the water vapor on the first convex arm 140 can be more easily guided by the clamping protrusion 141 to converge into water droplets and drip onto the bottom wall of the first clamping groove 120.
[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0054] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
