Drawing and screwing type assembly fixing device

Abstract

The invention relates to a drawing and screwing type assembly fixing device which comprises a solar module to be tested, two longitudinal bars, two transverse bars, support columns, drawing plates and through bolts, wherein the two transverse bars are parallel to each other and are mounted on the two longitudinal bars, the transverse bars are perpendicular to the longitudinal bars, the longitudinal bar are provided with longitudinal regulating grooves, the through bolts are sleeved in the longitudinal regulating grooves, the transverse bars are sleeved on the through bolts through fixing holes arranged at both ends thereof, one support column and one drawing plate are sleeved on each through bolt, each drawing plate is provided with a regulating groove and a lifting hole, the distance from the lower end surface of the drawing plate to the bottom of the support column is more than the thickness of the solar module to be tested, and the solar module to be tested is fixed on the lower end surface of the drawing plate by a suspension bolt through a mounting hole in an aluminum border. The invention is simple and convenient in regulation, and an operator only needs to bear the weight of the solar module in the whole testing process, thereby ensuring convenient operation, greatly reducing the labor intensity of the operator and improving the working efficiency.

Description

Technical field: [0001] The invention relates to a static pressure test device for a solar battery module, in particular to a hook-type component fixing device for the static pressure test of a solar battery module. Background technique: [0002] Solar cell modules must bear the pressure of strong winds and the gravity of ice and snow during long-term outdoor use. Therefore, it is necessary to simulate the real situation to test the pressure-bearing performance of solar cell modules. According to IEC standards, in order to test the safety factor of modules against gusts, solar cells are required. The module can withstand a pressure greater than 2400Pa; in order to test the safety factor of the module relative to rain and snow, it is required that the solar cell module can withstand a pressure greater than 5400Pa. For this reason, people must test the pressure bearing capacity of the surface of the solar cell module, uniformly apply a pressure of 2400Pa to the back of the sol...

Problems solved by technology

The specific installation requirements are: place the glass surface of the solar cell module 3 downwards, make the slot 11 on the strip steel pipe 1 align with the installation hole 31 on the aluminum frame, and use bolts to pass through the installation hole 31 and the slot 11 to connect the strip The steel pipe 1 is fixedly installed on the back of the aluminum frame of the solar cell module 3, and then the strip-shaped steel pipe 1 with the solar cell module 3 placed on the rectangular frame 21, so that the glass surface of the solar cell module 3 is suspended downward, and the process can be started. Static pressure test is carried out, so as to simulate the real situation of solar cell module 3 when it is used outdoors, but because strip steel pipe 1, solar cell module 3 and placement frame 2 are all relatively heavy, and the volume is relatively large, it is difficult to place and carry each time. It is very laborious and difficult to operate. Using this kind of test stand is not only too cumbersome to operate, but also takes a long time to operate
