Device for testing mechanical load of photovoltaic modules

Abstract

The invention discloses a device for testing mechanical load of photovoltaic modules. The device comprises fixed frames and photovoltaic modules, wherein sliding rails are arranged inside the fixed frames; the photovoltaic modules are mounted among four fixed frames which are mutually symmetric in pairs; mutually symmetric photovoltaic module sliding blocks are arranged at two ends of each photovoltaic module; mutually symmetric sensors are arranged on two sides of each photovoltaic module sliding block. The device has the beneficial effects that the sliding blocks and the sliding rails are mounted, so that pressing parts which are sand bags can be uniformly placed between a pressure platform and the photovoltaic modules; the testing process is facilitated; the photovoltaic modules can bedynamically and statically measured; the measurement is more efficient and rapid; a plurality of photovoltaic modules can be simultaneously tested; infrared measurement instruments are mounted on thesliding blocks of the photovoltaic modules, so that the load limit of the photovoltaic modules can be accurately measured; the measured load limit is less in error and more accurate.

Description

technical field [0001] The invention belongs to the related technical field of photovoltaic module testing devices, and in particular relates to a photovoltaic module mechanical load testing device. Background technique [0002] The photovoltaic module mechanical load testing machine is used to verify the ability of the module to withstand static and dynamic loads such as wind, snow or ice under different installation angles. It is widely used in testing the compressive strength test of photovoltaic modules, adopts dynamic pressure holding technology, and simulates the load test to understand the compressive capacity of the product under load. [0003] The photovoltaic industry has developed very rapidly in the past few years in China, and the quality of components is uneven. Now the photovoltaic industry is facing a reshuffle, survival of the fittest, and the survival of enterprises must be based on quality. As the industry has put forward higher requirements for quality, ...
