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

The invention discloses a fixing device for a pull hook assembly, which comprises a solar battery pack to be tested, longitudinal rods, cross rods, support columns, pull plates and long bolts, wherein the two cross rods are arranged on the two longitudinal rods in parallel, the cross rods are vertical to the longitudinal rods, each longitudinal rod is provided with a longitudinal adjusting groove, the long bolts are sheathed in the longitudinal adjusting grooves, the cross rods are sheathed on the long bolts through fixing holes arranged at two ends, the supporting column and the pull plate are also sleeved on each long bolt, each pull plate is provided with an adjusting groove and a U-shaped bracket, the distance between the lower end surface of each pull plate and the bottom of the supporting columns is larger than the thickness of the solar battery pack to be tested, and the U-shaped brackets on the pull plates hook a fixing plate on an aluminum frame. The pull hook assembly is simple and convenient to adjust; and in the whole testing process, an operator only needs to bear the weight of the solar battery pack, and therefore, the fixing device is light and convenient to operate, greatly reduces the labor intensity of the operator, and improves 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...
