[0014] The utility model provides a photovoltaic glass impact resistance testing device. Compared with the prior art, the following beneficial effects are achieved:

[0015] (1) The photovoltaic glass impact resistance test device adjusts the positions of the placement plates on both sides by starting the driving cylinders on both sides, then pulls the control handle to drive the fixed rod and the fixed plate to slide upward synchronously, causing the spring to start contracting. Subsequently, the photovoltaic glass is placed inside the placement plate. Under the influence of the spring elasticity, the fixed plates on both sides clamp and fix the photovoltaic glass. Driven by the driving cylinders, the position between the placement plates on both sides can be adjusted for photovoltaic glasses of different sizes, and under the influence of the spring elasticity, the photovoltaic glass is clamped and fixed, thus avoiding the situation of shaking and falling of the photovoltaic glass during subsequent impact resistance tests.

[0016] (2) The photovoltaic glass impact resistance test device adjusts the height of the placement box by starting the electric telescopic rod, places the iron block inside the notch opened inside the placement box and on the surface of the sliding plate. Then, by starting the control cylinder, the piston rod, the sliding plate on the left side and the sliding block slide synchronously, causing the sliding block to slide on the inner surface of the arc-shaped groove, and then the rotating disk starts to rotate. The rotation of the rotating disk causes the sliding block on the right side to slide on the inner surface of the arc-shaped groove on the right side, thereby causing the sliding plates on both sides to slide synchronously towards the relative or opposite sides, realizing the opening and closing of the notch inside the placement box, making the iron block fall onto the surface of the photovoltaic glass, and realizing the test of the impact resistance of the photovoltaic glass. Finally, the height of the placement box is adjusted by the electric telescopic rod and the scale, and by using iron blocks of different weights, the continuous test operation of the impact resistance of the photovoltaic glass is realized.

[0028] Embodiment 2

[0029] The main difference from Embodiment 1 is that:
