[0002] When performing a PID test on a photovoltaic module, the photovoltaic module needs to be fixed first, and then the photovoltaic module is powered on for testing. In order to facilitate the power-on test of the photovoltaic module, the photovoltaic module is usually placed on a test bench and fixed before testing.

[0003] A Chinese patent with announcement number CN216531241U discloses a PID test sample placement device, including a base plate, a shell is installed on the upper surface of the base plate, a first mounting plate and multiple second mounting plates are arranged inside the shell, a fixed block corresponding to the position of the annular member is installed on the first mounting plate, the fixed block and the annular member are connected by multiple connecting rods, multiple mounting blocks are also arranged between the fixed block and the annular member, and the mounting blocks slide along the sides of the fixed block and the annular member. When placing the photovoltaic component, the photovoltaic component is first placed between the first mounting plate and the second mounting plate, and between the second mounting plate and the second mounting plate, and then the screw is rotated through the fixing plate so that the screw rotates in the threaded tube, so that the mounting block will resist the fixed block while rotating, thereby driving the first mounting plate to slide on the first fixing rod and the second fixing rod, thereby clamping the photovoltaic component.

[0004] However, after the frameless photovoltaic module is placed by the above device, the second mounting plate will directly contact and squeeze the frameless photovoltaic module when the frameless photovoltaic module is clamped, which will easily increase the probability of damage to the frameless photovoltaic module. Utility Model Content

[0005] In order to reduce the possibility of damage to photovoltaic modules due to squeezing, the present application provides a support device for photovoltaic module PID testing, which adopts the following technical solution:

At this time, the second positioning plate is pulled to adjust the distance between the first positioning plate and the second positioning plate. When the first hole is connected to the locking hole, under the action of the first spring, one end of the clamping block is inserted into the locking hole, thereby locking the distance between the first positioning plate and the second positioning plate.

[0014] Optionally, the sliding rod is provided with a second scale, and the second scale is arranged along the length direction of the sliding rod.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a supporting device for PID testing of photovoltaic modules.

[0036] Reference Figure 1 and Figure 2 In order to be able to place photovoltaic modules of different thicknesses, the spacing between the first positioning plate 5 and the second positioning plate 6 is set to be adjustable. In order to accurately adjust the distance between the first positioning plate 5 and the second positioning plate 6, a first scale 9 is provided on the optical rod 72, and the first scale 9 is arranged along the length direction of the optical rod 72. A fastening screw 10 is threadedly connected to the first cross plate 51, and one end of the fastening screw 10 is pressed against the support rod 3.

[0037] The implementation principle of Example 1: When in use, the operator adjusts the distance between the first positioning plate 5 and the second positioning plate 6 through the adjustment member, and adjusts the distance between the first positioning plate 5 and the second positioning plate 6 by observing the indication of the first scale 9. When the distance between the two is adjusted to an appropriate position, the photovoltaic component is placed in the placement seat 4. Therefore, the possibility of first placing the photovoltaic component and then adjusting the first positioning plate 5 and the second positioning plate 6, which may cause damage to the photovoltaic component due to squeezing, is reduced. The provision of multiple placement seats 4 facilitates the placement of multiple photovoltaic components for testing.

[0038] Embodiment 2:

[0039] The difference between this embodiment and the embodiment is that, referring to Figure 1 , Figure 3 and Figure 4 The adjusting assembly includes a sliding rod 11, a clamping block 12 and a first spring 13. One end of the sliding rod 11 is connected to the first positioning plate 5, and the other end is connected to the second positioning plate 6. The second positioning plate 6 includes a second transverse plate 61 and a second vertical plate 62. A positioning hole 14 for inserting the sliding rod 11 is opened at the end of the second transverse plate 61. A plurality of locking holes 15 are opened on the side wall of the second transverse plate 61. The plurality of locking holes 15 are all connected to the positioning hole 14, and the plurality of locking holes 15 are arranged along the length direction of the second transverse plate 61.

[0040] Reference Figure 1 , Figure 3 and Figure 4A first hole 16 is provided on the sliding rod 11, one end of the first spring 13 is connected to the first hole 16, and the other end is connected to the clamping block, one end of the clamping block is inserted into the locking hole 15 and fits with the side wall of the locking hole 15, and a second scale 17 is provided on the top wall of the sliding rod 11, and the second scale 17 is provided along the length direction of the sliding rod 11.

[0041] Reference Figure 1 , Figure 3 and Figure 5 In the actual spacing adjustment process, since there is a spacing between two adjacent locking holes 15, the adjusted spacing value is also fixed, which inevitably causes a gap between the first positioning plate 5 and the second positioning plate 6 and the photovoltaic component. In order to solve the above problem, a fine-tuning hole 18 is opened on the side wall of the first horizontal plate 51, and a second hole 19 that slides with the sliding rod 11 is opened on the side wall of the first horizontal plate 51 facing the second horizontal plate 61. The fine-tuning hole 18 is connected to the second hole 19, and a locking member for locking the sliding rod 11 is provided in the fine-tuning hole 18.

[0042] Reference Figure 3 and Figure 5 The locking member includes a locking screw 20, which is threadedly connected to the fine-tuning hole 18, and one end of the locking screw 20 is pressed against the side wall of the sliding rod 11. In order to reduce the possibility that the first positioning plate 5 and the second positioning plate 6 are displaced by the collision of the photovoltaic module during the placement of the photovoltaic module, an anti-skid pattern 21 is provided on the end surface of the locking screw 20, and an anti-skid groove 22 is provided on the side wall of the sliding rod 11. The anti-skid groove 22 is arranged along the length direction of the sliding rod 11, and a rubber pad 23 is connected to the anti-skid groove 22 through Velcro (not shown in the figure), and the anti-skid pattern 21 is pressed against the rubber pad 23.

[0043] The implementation principle of Example 2 is as follows: during adjustment, the operator presses the clamping block so that the first spring 13 is compressed until the clamping block completely enters the first hole 16. At this time, the second positioning plate 6 is pulled to adjust the distance between the first positioning plate 5 and the second positioning plate 6. When the first hole 16 is connected to the locking hole 15, under the action of the first spring 13, one end of the clamping block is inserted into the locking hole 15, thereby locking the distance between the first positioning plate 5 and the second positioning plate 6. Then the operator loosens the locking screw 20. At this time, one end of the second positioning plate 6 at the sliding rod 11 is fixed. By sliding the first positioning plate 5, the distance between the first positioning plate 5 and the second positioning plate 6 can be further adjusted. When the spacing requirement of the photovoltaic components to be placed is reached, it is locked by the locking member to achieve precise adjustment.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
