Description

Simulated hail impact test device

technical field

The utility model relates to a test device for a solar battery panel, in particular to a test device for simulating a hail impact on a solar battery panel.

Background technique

The steel ball impact test of the solar cell panel in the prior art is to judge the quality of the cell panel by manually holding the steel ball, and judging the damage degree of the cell panel by the steel ball (the number of fragments per unit area, the detachment situation). The hand-held steel ball falls freely, the height and dimension are not easy to control, and the instantaneous impact speed is inaccurate, which leads to inaccurate judgment of the quality of the battery board. The outdoor use environment of solar panels is relatively harsh, and sometimes there will be hail weather, and the landing of hail will cause damage to the solar panels. Now it is necessary to simulate the damage of the battery panel by simulating the hail crash.

Contents of the invention

Purpose of the invention: The purpose of this utility model is to address the deficiencies of the prior art, to provide a simulated hail impact test device for simulating damage to solar panels in hail weather, and to judge the mechanical strength and quality of solar panels.

Technical solution: In order to realize the above-mentioned purpose of the invention, the technical solution adopted in the utility model is:

A device for simulating a hail impact test, comprising a base for placing solar panels, a funnel for storing free-falling steel balls is arranged above the base, and the funnel is provided with a valve to control the falling of the steel balls, The base includes a base, a middle plate and a table from bottom to top, and a reciprocating mechanism for reciprocating the table in different directions is arranged between the base, the middle plate and the table. A reciprocating mechanism for moving the table top in the Y direction is provided between the base and the middle plate, and a reciprocating mechanism for moving the table top in the X direction is provided between the middle plate and the table top.

The reciprocating mechanism is a screw transmission mechanism, and a servo motor is arranged at the end of the screw rod of the screw transmission mechanism, and the servo motor is connected to the PC through a servo driver. The random movement of the table is controlled by PC software programming, and the two reciprocating mechanisms that make the table move in different directions continue to move under the control of the PC. The steel balls in the funnel fall and hit different positions on the solar panel, simulating the falling of hail Case.

The valve is an electromagnetic valve, and the control circuit of the electromagnetic valve is connected with a PC.

Beneficial effects: Compared with the prior art, the utility model has the beneficial effects that: the solar battery panel is placed on the table, and the table moves along the X and Y directions driven by the reciprocating mechanism, and the steel ball falls freely from the funnel and hits the solar battery. On the board, it realistically simulates the impact of hailstones on the solar panels, and the quality of the solar panels can be controlled according to the damage of the solar panels, so that they can be put into a suitable environment for application.
