Description

The Drawable hook type component fixing device

Technical field:

The present invention relates to static pressure testing device of solar cell assembly, relate in particular to solar module static pressure test pothook type component fixing device.

Background technology:

Solar module must bear the pressure of strong wind and the gravity of ice and snow in long-term outdoor use procedure, therefore the load performance that needs Reality simulation situation test solar module, according to the IEC standard, for the safety coefficient of test suite for fitful wind, need solar module can bear the pressure that is greater than 2400Pa; For the safety coefficient of test suite with respect to sleet, need solar module can bear the pressure that is greater than 5400Pa.People must carry out the bearing capacity test to the solar module surface for this reason, the back side to solar module evenly applies 2400Pa pressure, the assembly front surface is evenly applied to the pressure of 5400Pa, the pressurized solar module is carried out to coherent detection and judgement, and meet the following conditions: 1. Non-intermittent breaking phenomena in experimentation; 2. without serious open defect; 3. under standard test condition the peak power output pad value be no more than the test before 5%; 4. insulation resistance is with identical before experiment.

At present, the module testing shelf structure that solar module is tested to use as shown in Figure 1, it comprises two bar shaped steel pipes 1 and places framework 2, placing framework 2 is comprised of a rectangle frame 21 and four support bars 22, support bar 22 is arranged on four angles of rectangle frame 21, the interior rectangular area of rectangle frame 21 is greater than the area of solar module 3, the length of bar shaped steel pipe 1 is greater than the length of rectangle frame 21, during use, bar shaped steel pipe 1 directly is placed on rectangle frame 21, both sides at bar shaped steel pipe 1 all have slotted eye 11, the position of slotted eye 11 is corresponding to the position of mounting hole 31 on solar module 3 aluminium frames.When the glass surface to solar module 3 is tested, solar module 3 is directly placed on the test desktop, make the glass surface of solar module upwards, then evenly exert pressure.When the back side to solar module 3 is tested, because glass surface must be downwards, must the glass surface of solar module 3 is unsettled, need to solar module 3 is fixed up and be exerted pressure with the module testing frame, preventing that the glass surface stress deformation is obstructed affects the accuracy of test result.Concrete installation requirement is: the glass surface of solar module 3 is kept flat downwards, the mounting hole 31 that slotted eye 11 on bar shaped steel pipe 1 is aimed on the aluminium frame, bar shaped steel pipe 1 is fixedly mounted on to the back side of the aluminium frame of solar module 3 with bolt through mounting hole 31 and slotted eye 11, and then the bar shaped steel pipe 1 that solar module 3 will be housed is placed on rectangle frame 21, make the glass surface of solar module 3 unsettled downwards, can start to carry out static pressure test, truth when ability analog solar battery component 3 is used out of doors like this, but due to bar shaped steel pipe 1, solar module 3 and placement framework 2 are all heavier, and volume ratio is larger, the each placement, carry all gruelling, and it is not easy to operate, not only operating process is too loaded down with trivial details to use this testing jig, and the running time is longer.

Summary of the invention:

In order more easily solar module to be carried out to static pressure test, the invention provides a kind of Drawable hook type component fixing device, not only use lightly, and carrying, collection are convenient, can significantly alleviate operator's labour intensity.

The technical solution adopted in the present invention is:

A kind of Drawable hook type component fixing device, it is characterized in that: it comprises solar module to be measured, longitudinal rod, transverse bar, support column, pull plate and thru-bolt, two longitudinal rods are parallel, contour, be horizontally fixed on frame, spacing between two longitudinal rods is greater than the width of solar module to be measured, two transverse bars are arranged on two longitudinal rods in parallel to each other, transverse bar is vertical with longitudinal rod, be provided with vertical regulating tank on longitudinal rod, thru-bolt is sleeved in vertical regulating tank, two ends at transverse bar are provided with fixed orifice, transverse bar is sleeved on thru-bolt by the fixed orifice that two ends are set, support column is sleeved on thru-bolt, be provided with regulating tank and U-shaped bracket on pull plate, pull plate is sleeved on thru-bolt by regulating tank, and be positioned at the upper end of support column, the lower surface of pull plate is greater than the thickness of solar module to be measured to the distance of support column bottom, held the fixed head on the aluminium frame of solar module to be detected by the U-shaped bracket hook on pull plate.

Due to the intersecting parallels structure that component fixing device is designed to formed by transverse bar and longitudinal rod, longitudinal rod is fixed on frame, be provided with vertical regulating tank on longitudinal rod, thru-bolt is sleeved in vertical regulating tank, the two ends of transverse bar are sleeved on thru-bolt by fixed orifice, support column and pull plate all are sleeved on thru-bolt, and pull plate can remove by relative thru-bolt by regulating tank.When applied voltage test is carried out in the front to solar module, unclamp the nut on thru-bolt, regulate the spacing between two transverse bars, make it with solar components length direction to be measured shelve require corresponding, then pull plate is pushed to the position parallel with longitudinal rod, screw the nut on thru-bolt, manually lift solar module, make the glass surface of solar module upwards, the back aluminium frame directly is shelved on two transverse bars and can carries out applied voltage test, after positive applied voltage test finishes, take out of solar module and overturn 180 °, make the aluminium frame at the solar module back side upwards, unclamp the nut on thru-bolt, regulate the position of pull plate, make the U-shaped bracket hook on pull plate hold the fixed head on the aluminium frame, finally the nut on thru-bolt is screwed, solar module just is suspended on four pull plate lower surfaces like this, be greater than the thickness of solar module to the distance of support column lower surface due to the pull plate lower surface, while therefore at the back side to solar module, carrying out applied voltage test, the glass surface deflection can not be subject to any stopping, guaranteed the accuracy of back side applied voltage test.

This solar module static pressure test Drawable hook type component fixing device, use adjusting simple and convenient, the maximum weight that the operator will carry in whole test process is exactly the weight of solar module, without any condiment, and volume does not increase simple and convenient yet, greatly alleviate operating personnel's labour intensity, also improved work efficiency.
