Description

Technical Field

[0001] The utility model relates to the technical field of hail test, and more specifically, to a hail impact testing machine. Background Art

[0002] A hail impact test device is a test device that uses artificially made ice balls to simulate hailstones in a natural environment and evaluates and verifies the ability of a workpiece to resist hail impact at the end of the test;

[0003] The hail impact test device for photovoltaic modules is composed of four devices tightly combined to form an organic operating whole to complete the entire process of the hail impact test. It mainly consists of:

[0004] 1. Pneumatic launching device: That is, the starting control part for hail impact launching;

[0005] 2. Mechanical moving device: That is, the transmission control part for different impact test areas of the photovoltaic module;

[0006] 3. Sample fixing rack: That is, the fixing device for the test photovoltaic module;

[0007] 4. Speed testing device: That is, the control part for the hail launching speed.

[0008] However, in the current hail impact test device, the pneumatic launching device used to launch ice balls mainly consists of a gas cylinder connected with a valve and a fixture for storing ice balls. During the launching preparation stage, it is necessary to support the ice ball with a supporting film and place it in the fixture, and then push the valve against the mold to form a seal. When moving the valve against the mold, it is mainly manually operated by the staff. In actual operation, it is rather laborious and prone to the problem of incomplete sealing and air leakage, resulting in inaccurate impact data due to air pressure leakage when the ice ball is fired. In view of this, we propose a hail impact testing machine. Content of the Utility Model
