By setting the adjustment structure 3, the hook 311 can be easily adjusted to control the stainless steel barrel 316 and the crucible 317. There is no need for personnel to directly use their hands to move the hook 311, which improves the safety and convenience of the experimental process.

[0040] The following describes in detail the specific settings and functions of the adjustment structure 3.

[0041] Reference Figures 2 to 4As shown, in this embodiment: the adjustment structure 3 also includes a support plate 314, the lower surface of the support plate 314 is fixedly connected to the upper surface of the base plate 1, the upper surface of the support plate 314 is fixedly connected to a workbench 315, the stainless steel barrel 316 and the crucible 317 are both placed on the upper surface of the workbench 315, before using the experimental device to perform a heat and cold resistance impact test on the photovoltaic glass, the stainless steel barrel 316 and the crucible 317 can be placed on the workbench 315 for preparatory work before the experiment, a stopwatch 320 is installed on one side of the support plate 314, and by setting the stopwatch 320, the heat and cold resistance test of the photovoltaic glass can be accurately performed. The time is controlled, the side thread of the fixed seat 306 is penetrated by a screw rod 303, the screw rod 303 is rotatably connected to the inner wall of the sliding hole 302, and the rotating screw rod 303 can drive the fixed seat 306 to move, thereby achieving the effect of conveniently controlling the fixed seat 306, and the side sliding of the fixed seat 306 is penetrated by a plurality of guide rods 307, the guide rods 307 are fixedly connected to the inner wall of the sliding hole 302, and the fixed seat 306 moves along the inner wall of the sliding hole 302.

The welding plate One side of 312 is fixedly connected with a positioning tube 313, and the inner wall of the positioning tube 313 is slidably connected to the arc surface of the connecting rope 310. During the process of the reel 308 retracting and releasing the connecting rope 310, the positioning tube 313 can limit the connecting rope 310, thereby improving the stability of the connecting rope 310 during movement. The connecting rope 310 is specifically a steel wire rope. By setting the connecting rope 310 as a steel wire rope, the steel rope is resistant to high temperature, cold and corrosion, and is suitable for occasions requiring high temperature resistance and strength. One side of the fixing seat 306 is fixedly connected with a motor 309, and the output end of the motor 309 is fixedly connected to one side of the reel 308. When the motor 310 is started, 09 can drive the reel 308 to rotate automatically, thereby improving the degree of automation of the impact test device.

The screw rod 303 is specifically made of stainless steel. By setting the material of the screw rod 303 to stainless steel, the oxidation rate of the screw rod 303 is reduced, thereby increasing the service life of the screw rod 303.

[0042] When it is necessary to use an experimental device to conduct heat and cold resistance tests on photovoltaic glass, the following steps need to be performed:

[0043] S1. Sampling photovoltaic glass: 5 pieces of 60*20 and 5 pieces of 40*20 glass sheets are sampled to obtain photovoltaic glass samples;

[0044] S2. Etching the photovoltaic glass sample with a hydrofluoric acid solution to remove 2 μm of impurities on the surface of the glass sample, as well as sharp edges, micro-cracks and other external factors that may affect the glass itself during the experiment, thereby obtaining an etched glass sample;

[0045] S3, take one 60*20 and one 40*20 etched glass sample, and slowly put them into In a 316 stainless steel barrel to avoid damage to the etched glass specimens;

[0046] S4. Slowly place the stainless steel barrel 316 containing the etched glass sample into the liquid nitrogen tank 2. After the boiling sound in the liquid nitrogen tank 2 stops, start a 5-minute timer. After 5 minutes, slowly remove the stainless steel barrel. After a while, slowly pour the low-temperature sample in the barrel onto a soft cloth to prevent the glass sample from breaking. Observe the low-temperature sample and record it.

[0047] S5. After the low-temperature sample returns to room temperature, place the sample in the crucible 317 and put it in the 150°C oven 4 for 5 minutes. After 5 minutes, take it out of the oven 4 and observe and record the high-temperature sample.

[0048] S6, repeat the above steps for 6 cycles for each etched glass sample;

[0049] S7. After 6 cycles of 5 etched glass samples, the final sample results are formed.

[0050] When the adjustment structure 3 is needed to control the stainless steel barrel 316 and the crucible 317, the servo motor 305 is first started to drive the screw rod 303 to rotate, and the screw rod 303 drives the fixed seat 306 to move along the inner wall of the slide hole 302. When the fixed seat 306 drives the hook 311 to move to the top of the stainless steel barrel 316 containing the etched glass sample, the motor 309 is started to drive the reel 308 to rotate, so that the connecting rope 310 gradually falls off the arc surface of the reel 308. The connecting rope 310 drives the hook 311. When the hook 311 is moved to the top of the stainless steel barrel 316 containing the etched glass sample, the motor 309 is started to drive the reel 308 to rotate, so that the connecting rope 310 gradually falls off the arc surface of the reel 308. The connecting rope 310 drives the hook 311. After the cylinder 310 is moved to a suitable height, the hook 311 is used to hang the steel ring 319, and then the servo motor 305 is started to drive the screw 303 to rotate, the screw 303 drives the fixing seat 306, and the fixing seat 306 drives the hook 311 and the stainless steel barrel 316. When the stainless steel barrel 316 moves to the top of the liquid nitrogen tank 2, the motor 309 is started to drive the reel 308 to rotate, so that the connecting rope 310 drives the hook 311, and the hook 311 drives the stainless steel barrel 316 into the liquid nitrogen tank 2, and then the cold impact resistance test of the etched glass sample can be carried out. The above steps can also conveniently control the crucible 317 to enter the oven 4 to perform a temperature impact test on the etched glass sample. Before using the experimental device to perform a temperature and cold impact test on the photovoltaic glass, the stainless steel barrel 316 and the crucible 317 can be placed on the workbench 315 for pre-experimental preparation. In addition, by setting the stopwatch 320, the time of the temperature and cold resistance test of the photovoltaic glass can be accurately controlled. During the movement of the fixed seat 306 along the inner wall of the sliding hole 302, the guide rod 307 can guide and position it, thereby achieving the effect of improving the stability of the movement process of the fixed seat 306. During the process of the reel 308 retracting and releasing the connecting rope 310, the positioning tube 313 can limit the connecting rope 310, thereby achieving the effect of improving the stability of the movement process of the connecting rope 310. By setting the connecting rope 310 to be a steel wire rope, the steel rope is resistant to high temperature, cold and corrosion, and is suitable for occasions requiring high temperature resistance and strength. Finally, by setting the material of the screw rod 303 to stainless steel, the oxidation rate of the screw rod 303 is reduced, thereby improving the service life of the screw rod 303.
