Description

Technical Field

[0001] This application relates to the field of photovoltaic module testing technology, and in particular to a test bracket and test chamber. Background Technology

[0002] The photovoltaic module environmental test chamber is equipped with a test rack to support the photovoltaic modules under test. Existing test racks have a simple structure, only suitable for placing one of the photovoltaic modules or laminates. This limitation prevents simultaneous testing of both photovoltaic modules and laminates during the testing process. When both photovoltaic modules and laminates need to be tested, they must be tested separately, i.e., one is tested first, then the other. This results in frequent replacement of the tested components, readjustment of the test chamber's environmental parameters, low testing efficiency, and failure to fully utilize the test chamber's space resources.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] This application provides a test bracket for use within a test chamber to support photovoltaic modules and / or laminates for testing. The test chamber can be an environmental simulation test chamber, where the photovoltaic modules and / or laminates are placed, exposing them to a simulated test environment for performance testing. The test chamber can also be a hot spot testing chamber, etc. The test bracket provided in this application can be applied to various current or future test chambers. Figure 1 A schematic diagram of the structure of a test bracket according to an embodiment of this application is shown. Figure 1 As shown, the test support includes a first support 3, a second support 1, and a top plate 2. The first support 3 is used to support the photovoltaic modules. The first support 3 is fixed inside the test chamber. It can be a movable fixation, for example, placed inside the test chamber, or moved out as needed. Alternatively, the first support 3 can be fixed inside the test chamber and cannot be moved. Figure 2 A schematic diagram of the structure of the first support 3 according to an embodiment of this application is shown. Figure 2 As shown, the first support 3 is an L-shaped support, which includes a first horizontal plate and a first vertical plate 320. The first vertical plate 320 and / or the first horizontal plate are provided with grooves 311 for defining photovoltaic modules. Photovoltaic modules are inserted into the grooves 311, with one photovoltaic module inserted into each groove 311, so that the first support 3 can support multiple photovoltaic modules in the test chamber for testing. The number of grooves 311 or the size of the first horizontal plate is set according to the size of the test chamber. Figure 3 A schematic diagram of the connection between the second support 1 and the top plate 2 according to an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of an L-shaped rod according to an embodiment of this application is shown. Figures 1 to 4As shown, the second support 1 includes multiple L-shaped rods and limiting members for positioning the laminated components. Each L-shaped rod includes a second vertical rod 202 and a second horizontal rod 204. The top plate 2 is fixed to the test chamber and / or the first vertical plate 320. The second vertical rod 202 of the L-shaped rods is slidably connected to the top plate 2. The second support 1 is used to support the laminated components placed inside the test chamber for testing. Since the laminated components are relatively small compared to photovoltaic modules, they can be supported by the smaller second support 1. The limiting members are used to restrict the vertical placement of the laminated components on the second support 1. Each L-shaped rod has a limiting member, and each L-shaped rod supports one laminated component. The second vertical rod 202 of the L-shaped rod is slidably connected to the top plate 2. The L-shaped rod slides relative to the top plate 2 along a first direction, which is perpendicular or approximately perpendicular to the first horizontal rod 310. The slidable connection between the second vertical rod 202 and the top plate 2 allows the L-shaped rods to be evenly distributed along the first direction. When only multiple laminated components need to be tested, multiple laminated components can be evenly arranged inside the test chamber. The second vertical bar 202 of the L-shaped rod is slidably connected to the top plate 2, allowing the L-shaped rod to be distributed between two adjacent first horizontal bars 310. This enables the simultaneous testing of photovoltaic modules and laminates, allowing photovoltaic modules to be inserted onto the first horizontal bars 310, followed by laminates, and then another arrangement of photovoltaic modules, thus enabling the test support to support multiple photovoltaic modules and multiple laminates. The slidable connection between the second vertical bar 202 of the L-shaped rod and the top plate 2 allows for free adjustment of the L-shaped rod's position, facilitating the arrangement of photovoltaic modules and / or laminates.

[0028] The test bracket provided in this application embodiment can simultaneously test photovoltaic modules and laminates, thereby improving testing efficiency.

[0029] Especially during the research and development of new photovoltaic modules, multiple tests are required on different photovoltaic modules or laminates. The aforementioned test fixture enables efficient testing, shortens the development cycle of new products, and reduces development costs. The test fixture provided in this application embodiment is of great and far-reaching significance for improving the development speed of photovoltaic modules, enhancing quality inspection efficiency, and promoting the high-quality development of the photovoltaic industry.

[0030] In one embodiment, the first horizontal plate includes a plurality of first horizontal bars 310, all of which are fixedly connected to the first vertical plate 320.

[0031] In the first support 3, the first horizontal plate adopts multiple first horizontal bars 310, which can reduce material waste and reduce the weight of the first support 3.

[0032] The "plate" mentioned in this application embodiment is not limited to a solid plate, but can be a plate made up of multiple rods. That is, the plate can be a plate including multiple hollow areas. In some other examples, it can also be a solid plate.

[0033] In this embodiment, the first horizontal plate adopts multiple first horizontal bars 310, which also facilitates the position adjustment of the L-shaped bar, so as to easily move the L-shaped bar between the two first horizontal plates.

[0034] In this embodiment, the first horizontal plate adopts multiple first horizontal bars 310, which can also facilitate finding the position of the groove 311, so as to insert the photovoltaic module into the groove 311 more quickly and further improve the testing efficiency.

[0035] In one embodiment, the first vertical plate 320 is formed by a plurality of first connecting rods 321 connected in an alternating manner; the plurality of first connecting rods 321 include at least a vertically arranged first vertical rod 322, and the first vertical rod 322 is fixedly connected to the first horizontal rod 310.

[0036] The first vertical plate 320 is formed by interlacing multiple first connecting rods 321. The interlacing connection of the multiple first connecting rods 321 can be fixed by welding, threading, etc.

[0037] In one example, multiple first links 321 are interlocked to form a first vertical plate 320, which can be manufactured in one piece.

[0038] The first vertical plate 320 is formed by multiple first connecting rods 321 connected in an interlaced manner, which creates multiple hollow areas, reduces the weight of the first bracket 3, and facilitates the installation of the test bracket.

[0039] The plurality of first links 321 include at least a vertically arranged first vertical bar 322, which is fixedly connected to the first horizontal bar 310, so as to facilitate the fixed connection between the first horizontal bar 310 and the first vertical plate 320.

[0040] In one example, the first vertical plate 320 is formed by a plurality of first connecting rods 321 connected in a crisscross pattern, such as Figure 2 As shown.

[0041] In one embodiment, the top plate 2 is formed by a plurality of second connecting rods 501 and is fixed to one end of the first vertical plate 320 away from the first horizontal plate.

[0042] The top plate 2 is formed by multiple second connecting rods 501, creating a hollow area in the middle, which also saves materials.

[0043] The top plate 2 can be fixed to the top of the test chamber or to the side wall of the test chamber, and is located at the end of the first vertical plate 320 opposite to the first horizontal plate. The first horizontal plate is set near the bottom of the test chamber, and the top plate 2 is set near the top of the test chamber. There needs to be enough space between the top plate 2 and the first horizontal plate to accommodate the photovoltaic modules.

[0044] In one embodiment, the top plate 2 further includes at least one third link 502, and the number of second links 501 is four, with the four second links 501 forming a square; the third link 502 is fixed to two second links 501 on opposite sides of the first vertical plate 320, and the second vertical plate 202 is connected to the third link 502.

[0045] The top plate 2 is formed into a square by four second connecting rods 501. The third connecting rod 502 is fixed to the central area of ​​the top plate 2. The second vertical rod 202 is connected to the third connecting rod 502, allowing the second support 1 to be set within the space formed by the top plate 2 and the first support 3. The laminate can be placed on the second support 1 without adding or expanding additional space. This facilitates simultaneous testing of the laminate and photovoltaic modules without requiring additional space for the entire operation or the size of the test chamber, making the operation smoother.

[0046] In one embodiment, the third link 502 is slidably connected to the two second links 501.

[0047] The third link 502 and the two second links 501 can slide along a second direction, which can be the same as the extension direction of the first crossbar 310. The sliding of the third link 502 can adjust the position of the second bracket 1.

[0048] In one example, the third link 502 can be limited to sliding within a local length of the second link 501, which is adapted to the length difference between the first crossbar 310 and the second crossbar 204.

[0049] In one example, the third link 502 can slide within the full range of the second link 501, allowing for free adjustment of the position of the third link 502 during actual operation.

[0050] It is understandable that a limiting structure can be set on the second link 501 to limit the sliding range of the third link 502, thereby preventing the third link 502 from slipping.

[0051] In one embodiment, the second vertical rod 202 is slidably connected to the third connecting rod 502. This slidable connection between the second vertical rod 202 and the third connecting rod 502 achieves a slidable connection between the second vertical rod 2 and the top plate 2. The L-shaped rod slides relative to the top plate 2 along a first direction, which is perpendicular or approximately perpendicular to the first horizontal rod 310. The slidable connection between the second vertical rod 202 and the top plate 2 allows the L-shaped rods to be evenly distributed along the first direction. When only multiple laminates need to be tested, multiple laminates can be evenly arranged inside the test chamber. The slidable connection between the second vertical rod 202 and the top plate 2 also allows the L-shaped rods to be distributed between two adjacent first horizontal rods 310. This enables the simultaneous testing of photovoltaic modules and laminates, allowing photovoltaic modules to be inserted into the first horizontal rods 310, followed by laminates, and then another arrangement of photovoltaic modules, thus enabling the test bracket to support multiple photovoltaic modules and multiple laminates. The second vertical rod 202 in the L-shaped rod is slidably connected to the top plate 2, which allows the position of the L-shaped rod to be freely adjusted, facilitating the arrangement of photovoltaic modules and / or laminates.

[0052] In one embodiment, the number of first horizontal bars 310 is N, where N is a positive integer greater than or equal to 2; the number of second vertical bars 202 is M times N-1, where M is a positive integer greater than or equal to 1.

[0053] The number of first crossbars 310 is adapted to the size of the test chamber.

[0054] In one example, for instance, if 10 photovoltaic modules can be tested simultaneously in an existing test bracket, then 10 first crossbars 310 or 10 grooves 311 are required; in the test bracket of this application embodiment, 10 first crossbars 310 can be set, or less than 10 first crossbars 310 can be set, with less than 10 used to leave space for the second bracket 1.

[0055] The second vertical bar 202 can be set between two first horizontal bars 310. M second vertical bars 202 can be set between every two first horizontal bars 310, so the number of second vertical bars 202 is M times N-1.

[0056] During the testing process, if there are 10 first horizontal bars 310, only 5 photovoltaic modules need to be tested. Alternatively, multiple second vertical bars 202 can be slid to the edge, and the remaining space can be used to place 5 photovoltaic modules.

[0057] In one embodiment, the spacing between adjacent first crossbars 310 is adapted to be M times the width of the second crossbar 204.

[0058] The second crossbar 204 is used to support the laminate. M second crossbars 204 are placed between adjacent first crossbars 310. The spacing between adjacent first crossbars 310 is adapted to M times the width of the second crossbar 204. The spacing between adjacent first crossbars 310 is greater than M times the width of the second crossbar 204, so that there is enough space between adjacent first crossbars 310 to accommodate M second crossbars 204. In order to have a preset gap between adjacent laminates, the spacing between adjacent first crossbars 310 is slightly greater than M times the width of the second crossbar 204.

[0059] In one embodiment, the limiting member includes a fourth link 203, two fourth links 203 are respectively fixed to opposite sides of the L-shaped rod, and the two ends of the fourth link 203 are respectively connected to the second vertical rod 202 and the second horizontal rod 204.

[0060] The laminate can be inserted between the two fourth links 203, allowing the two fourth links 203 to limit the position of the laminate, so that the laminate can be stably placed on the L-shaped rod. In this method, the laminate can be placed on the second support 1 conveniently and quickly, and the second crossbar 204 can be narrow, eliminating the need to stabilize the laminate by setting grooves on the second crossbar 204.

[0061] In some other examples, the laminate can also be stabilized in other ways, such as by setting grooves on the second crossbar 204.

[0062] In one embodiment, the second vertical rod 202 is rotatably connected to the second horizontal rod 204, and the fourth connecting rod 203 is rotatably connected to the second vertical rod 202 and / or the second horizontal rod 204.

[0063] In one example, the second vertical bar 202 and the second horizontal bar 204 are connected by a 90° rotation. When they are joined, they can be at 0° or less than 15°, and when they are opened, they are at 90° to facilitate the support of the laminate.

[0064] The second vertical rod 202 is rotatably connected to the second horizontal rod 204, and the fourth connecting rod 203 is rotatably connected to the second vertical rod 202 and / or the second horizontal rod 204, so that the second bracket 1 can be opened and closed. When opened, it is used to test the laminate. When the laminate does not need to be tested, it is closed to avoid occupying space and reduce the speed at which the photovoltaic module is affected by the simulated environment.

[0065] In one example, the first support 3 and the second support 1 of this application embodiment are further provided with a plurality of limiting protrusions 201 to assist in limiting the laminate and / or photovoltaic module, so as to more stably support the laminate and / or photovoltaic module.

[0066] This application also provides a test chamber, including a chamber body and a test bracket according to any of the above embodiments, wherein the test bracket is disposed inside the chamber body.
