[0018] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Embodiment

[0020] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 1 Fig. shows the front view schematic diagram of the test device in the embodiment, Figure 2 Fig. shows the sectional view schematic diagram of the test device in the embodiment; Figure 3 Fig. shows Figure 2 the enlarged schematic diagram of the structure at position A in

[0021] This device includes:

[0022] A test chamber 10 with a chamber door 11 hingedly arranged;

[0023] A clamping assembly, the clamping assembly includes clamping blocks 21 rotatably and symmetrically arranged on the inner side walls of the test chamber 10. A limiting screw 22 is movably inserted into the clamping block 21. A locking block 23 is arranged at the bottom end of the limiting screw 22. Both ends of the photovoltaic module 1 are inserted into the corresponding clamping blocks 21 on the side, and the locking block 23 abuts against the end of the photovoltaic module 1 to fix the photovoltaic module 1;

[0024] On the outer side wall of the test chamber 10, a driving member 26 is provided at a position corresponding to one of the clamping blocks 21. The output end of the driving member 26 is connected to the clamping block 21, and the driving member 26 drives the clamping block 21 to rotate so as to drive the clamped photovoltaic module 1 to rotate.

[0025] The chamber door 11 is hingedly provided on the front side of the test chamber 10, and the waterproof test of the photovoltaic module 1 is carried out inside the test chamber 10; opening the chamber door 11 facilitates the clamping and fixing of the photovoltaic module 1, and after the installation is completed, the chamber door 11 is closed for testing.

[0026] By providing a rotatable clamping assembly, after the photovoltaic module 1 is clamped and fixed, if it is necessary to perform waterproof tests on the photovoltaic module 1 at different angles, there is no need to disassemble and re-clamp and fix the photovoltaic module. It is only necessary to directly start the driving member 26 to rotate the clamping assembly to drive the photovoltaic module 1 to rotate and adjust the fixed angle, thereby improving the test efficiency.

[0027] Specifically, the clamping block 21 is U-shaped, and the open ends of the two U-shaped clamping blocks 21 are arranged opposite to each other, forming a slot. When clamping, the two end portions of the photovoltaic module 1 are placed in the slot. The limit screw 22 is vertically inserted into the clamping block 21, and the limit screw 22 is in threaded cooperation with the clamping block 21. By rotating the limit screw 22, the locking block 23 at the bottom end of the limit screw 22 can be driven to gradually approach the end portion of the photovoltaic module 1 until it abuts against the photovoltaic module 1. The locking block 23 and the clamping block 21 cooperate to achieve the clamping and fixing of the end portion of the photovoltaic module 1.

[0028] The driving member 26 is a motor. After the photovoltaic module 1 is clamped and fixed, by driving the clamping block 21 on one side to rotate through the driving member 26, the photovoltaic module 1 and the clamping block 21 on the other side can be driven to rotate synchronously, thereby realizing the angle adjustment of the photovoltaic module 1.

[0029] As Figure 3 shown, Figure 3 what is shown is Figure 2 an enlarged schematic view of the structure at A in

[0030] Installation shafts 24 are provided at one ends of the clamping blocks 21 close to the installation side wall of the test chamber 10, and bearings 25 connected to the installation shafts 24 are provided on the installation side wall.

[0031] The rotational connection between the clamping block 21 and the test chamber 10 is realized through the provided installation shafts 24 and bearings 25.

[0032] As Figure 2 shown, Figure 2 what is shown is a cross-sectional schematic view of the test device in the embodiment.

[0033] It further includes a testing component, and the testing component includes a water storage pipe 31 arranged at the top inside the testing box 10. A plurality of nozzles 32 communicating with the inner cavity of the water storage pipe 31 are uniformly arranged at one end of the water storage pipe 31 close to the clamping component;

[0034] The water storage pipe 31 is connected to an external water source, and water is sprayed out from the nozzles 32 and sprayed onto the photovoltaic module 1 to conduct a waterproof performance test on the photovoltaic module 1.

[0035] Specifically, in this embodiment, the water storage pipe 31 is fitted and installed on the side wall of the top inside the testing box 10.

[0036] The testing component further includes a water supply tank 33 with an opening at the top. The water supply tank 33 is arranged at the bottom inside the testing box 10. A water pump 34 is arranged inside the water supply tank 33. The output end of the water pump 34 is provided with a water delivery pipe 35, and the other end of the water delivery pipe 35 is communicated with the water storage pipe 31.

[0037] Water is injected into the water supply tank 33, and the water is transported to the water storage pipe 31 through the water pump 34 and the water storage pipe 31. The water supply tank 33 is arranged at the bottom inside the testing box 10. After the water is sprayed out by the nozzles 32, the water is caught by the water supply tank 33 again to form a cycle, avoiding waste of water source.

[0038] Working principle: When this device is in use, the two ends of the photovoltaic module 1 are placed at the open ends of the clamping blocks 21, and then the limiting screw 22 is rotated to drive the locking block 23 at the bottom end of the limiting screw 22 to gradually approach the end of the photovoltaic module 1 until it abuts against the photovoltaic module 1. The locking block 23 and the clamping block 21 cooperate to clamp and fix the end of the photovoltaic module 1. Then, the water pump 34 and the nozzles 32 are turned on to spray water onto the photovoltaic module 1 to conduct a waterproof performance test on the photovoltaic module 1;

[0039] During the test, if it is necessary to conduct waterproof tests on the photovoltaic module 1 at different angles, the driving member 26 is turned on to drive the photovoltaic module 1 to rotate to adjust the angle of the photovoltaic module 1.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
