[0003] In the prior art, the photovoltaic panel impact test mainly uses a driving device to control the impact ball to achieve the impact on the photovoltaic panel. During the impact process, since the driving device is usually not convenient for automatically retracting the impact ball after the impact is completed, it is easy for the photovoltaic panel to be tested to be hit for the second time, and the photovoltaic panel impact test effect is not good. In view of the shortcomings of the prior art, the utility model provides a mechanism for preventing secondary impact in the photovoltaic panel impact test to solve the above problems.

When the impact ball hits the photovoltaic panel to be tested, the delay relay is immediately energized after the timing is completed, and the electrically controlled air valve is controlled to be energized. The compressed air of the air compressor quickly pressurizes the large-stroke cylinder through the quick exhaust valve, and the push rod of the large-stroke cylinder quickly rebounds, tightening the protective wire rope and pulling the impact ball to prevent the impact ball from hitting the tested object again, thereby ensuring a good effect of the photovoltaic panel impact test.

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0018] The embodiment of the present application solves the problem in the prior art that the photovoltaic panel impact test mainly uses a driving device to control the impact ball to achieve impact on the photovoltaic panel, by providing a mechanism to prevent secondary impact in the photovoltaic panel impact test. During the impact process, since the driving device is usually not convenient for automatically retracting the impact ball after the impact is completed, it is easy for the photovoltaic panel to be tested to be hit twice, resulting in poor photovoltaic panel impact test results.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] The embodiment of the utility model discloses a mechanism for preventing secondary impact in a photovoltaic panel impact test. Figure 1 As shown, it includes an air compressor 1 and a mounting bracket 2 set on the ground, the mounting bracket 2 is provided with a long-stroke cylinder 3 connected to the air compressor 1, and the output end of the long-stroke cylinder 3 is provided with a push rod 31; the mounting bracket 2 is provided with a photovoltaic panel 9 to be tested corresponding to the position of the impact ball 5.

[0021] The mounting bracket 2 is connected to a hanging rope 51, on which a striking ball 5 is provided, and a protective steel wire rope 4 is connected between the striking ball 5 and the push rod 31;

[0022] An electric-controlled air valve 6 is provided between the pipeline between the air compressor 1 and the large-stroke cylinder 3. The electric-controlled air valve 6 is connected to a time delay relay 7. The time delay relay 7 is provided with a release switch 71. A quick exhaust valve 8 is provided between the pipeline between the large-stroke cylinder 3 and the electric-controlled air valve 6.

[0023] When the device is testing, the air compressor 1 is used to provide power. When the release switch 71 is closed, the compressed air of the air compressor 1 is used to reduce the pressure of the large-stroke cylinder 3 through the quick-release valve 8. The push rod 31 of the large-stroke cylinder 3 is pushed out, and the protective wire rope 4 is pulled by the gravity of the impact ball 5. The impact ball 5 begins to swing down. At this time, the release switch 71 starts the timing of the delay relay 7. When the impact ball 5 hits the photovoltaic panel 9 to be tested, the delay relay 7 is immediately energized after the timing is completed, and the electronically controlled air valve 6 is controlled to be energized. The compressed air of the air compressor 1 is used to quickly pressurize the large-stroke cylinder 3 through the quick-release valve 8. The push rod 31 of the large-stroke cylinder 3 rebounds quickly, tightening the protective wire rope 4 and pulling the impact ball 5 to prevent the impact ball 5 from hitting the test piece again.

[0024] The quick exhaust valve 8 is fixedly connected to the mounting bracket 2 , and the mounting bracket 2 is used to provide support and limit for the quick exhaust valve 8 , thereby ensuring that the force on the quick exhaust valve 8 is stable.

[0025] A load-bearing bracket 22 is fixedly connected to the quick exhaust valve 8, and the load-bearing bracket 22 is used to provide support for the electric control gas valve 6 and the time delay relay 7. The device uses the load-bearing bracket 22 to limit the electric control gas valve 6 and the time delay relay 7, so that the force on the electric control gas valve 6 and the time delay relay 7 is stable.

[0026] The mounting bracket 2 is provided with a fixed pulley 21 for providing support and limitation for the protective steel wire rope 4. The design of the fixed pulley 21 stabilizes the force applied to the protective steel wire rope 4, thereby achieving good control over the impact ball 5.

[0027] The mechanism for preventing secondary impact in the photovoltaic panel impact test is as follows: when the photovoltaic panel 9 to be tested is tested, the photovoltaic panel 9 to be tested is fixed on the mounting bracket 2, the quick exhaust valve 8 and the large-stroke cylinder 3 are installed on the mounting bracket 2, the impact ball 5 is hung on the mounting bracket 2 by the hanging rope 51, the air pipe of the air compressor 1 is connected to the electric control air valve 6, the quick exhaust valve 8 and the large-stroke cylinder 3, the release switch 71 is connected to the electric control air valve 6 and the delay relay 7 through a cable, one end of the protective wire rope 4 is connected to the push rod 31 of the large-stroke cylinder 3, and the other end is connected to the impact ball 5, thereby realizing the assembly of the entire device. The overall structure of the device is compact and easy to maintain, meeting the use requirements.
