Description

Pull solid-spin assembly stationary installation

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 assembly stationary installation.

Background technology:

Solar module must bear the pressure of strong wind and the gravity of ice and snow in long-term outdoor use, therefore the load performance that needs simulation truth test solar module, according to the IEC standard, for the safety coefficient of test suite, need solar module can bear pressure greater than 2400Pa for fitful wind; For the safety coefficient of test suite, need solar module can bear pressure greater than 5400Pa with respect to sleet.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 the pressure of 5400Pa, the pressurized solar module is carried out coherent detection and judgement, and meet the following conditions: 1. no intermittent breaking phenomena in the experimentation; 2. there is not serious open defect; 3. under the standard test condition peak power output pad value be no more than the test before 5%; 4. insulation resistance is preceding identical with experiment.

At present, the module testing shelf structure that solar module is tested usefulness as shown in Figure 1, it comprises two bar shaped steel pipes 1 and places framework 2, placing framework 2 is made up of a rectangle frame 21 and four support bars 22, support bar 22 is installed 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 the rectangle frame 21, both sides at bar shaped steel pipe 1 all have slotted eye 11, and the position of slotted eye 11 is corresponding to the position of mounting hole 31 on the solar module 3 aluminium frames.When the glass of solar module 3 is tested, solar module 3 is directly placed on the test desktop, the glass of solar module is made progress, evenly exert pressure then.When the back side of solar module 3 is tested, because glass must be downwards, must the glass of solar module 3 is unsettled, need solar module 3 be fixed up with the module testing frame and exert pressure, preventing that the glass stress deformation is obstructed influences precision of test result.Concrete installation requirement is: the glass of solar module 3 is kept flat downwards, the mounting hole 31 that slotted eye 11 on the bar shaped steel pipe 1 is aimed on the aluminium frame, pass the back side that mounting hole 31 and slotted eye 11 are fixedly mounted on bar shaped steel pipe 1 on the aluminium frame of solar module 3 with bolt, and then the bar shaped steel pipe 1 that solar module 3 will be housed is placed on the rectangle frame 21, make the glass of solar module 3 unsettled downwards, can begin to carry out static pressure test, truth when ability analog solar battery component 3 uses out of doors like this, but because bar shaped steel pipe 1, solar module 3 and placement framework 2 are all heavier, and volume ratio is bigger, 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 static pressure test, the invention provides a kind of pull solid-spin assembly stationary installation, not only use lightly, and carrying, collection are convenient, can alleviate operator's labour intensity significantly.

The technical solution adopted in the present invention is:

A kind of pull solid-spin assembly stationary installation, 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 the frame, spacing between two longitudinal rods is greater than the width of solar module to be measured, two transverse bars are installed on two longitudinal rods in parallel to each other, transverse bar is vertical with longitudinal rod, on longitudinal rod, be provided with vertical regulating tank, thru-bolt is sleeved in vertical regulating tank, two ends at transverse bar are provided with fixed orifice, transverse bar is sleeved on the thru-bolt by the fixed orifice that is arranged on two ends, and support column is sleeved on the thru-bolt; On pull plate, be provided with regulating tank and hole for hoist, pull plate is sleeved on the thru-bolt by regulating tank, and be positioned at the upper end of support column, the thickness of the distance of support column bottom greater than solar module to be measured is arrived in the lower surface of pull plate, and solar module to be detected is fixed on the lower surface of pull plate by Hanging bolt by the mounting hole on the aluminium frame.

Owing to the intersecting parallels structure that the assembly stationary installation is designed to form by transverse bar and longitudinal rod, longitudinal rod is fixed on the frame, on longitudinal rod, be provided with vertical regulating tank, thru-bolt is sleeved in vertical regulating tank, the two ends of transverse bar are sleeved on the thru-bolt by fixed orifice, support column and pull plate all are sleeved on the thru-bolt, and pull plate can remove by relative thru-bolt by regulating tank.When applied voltage test is carried out in the front of solar module, unclamp the nut on the 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 the position parallel, screw the nut on the thru-bolt, manually lift solar module with longitudinal rod, the glass of solar module is made progress, back side aluminium frame directly is shelved on two transverse bars can carries out applied voltage test; After positive applied voltage test finishes, take out of solar module and overturn 180 °, the aluminium frame at the solar module back side is made progress, unclamp the nut on the thru-bolt, regulate the position of pull plate, make the mounting hole on the hole for hoist aligning aluminium frame on the pull plate, by Hanging bolt that the two is fixedly connected, at last thru-bolt is screwed, solar module just is suspended on four pull plate lower surfaces like this, because the thickness of the distance of support column lower surface greater than solar module is arrived in the pull plate lower surface, therefore when applied voltage test is carried out at the back side of solar module, the glass deflection can not be subjected to any stopping, has guaranteed the accuracy of back side applied voltage test.

This solar module static pressure test pull solid-spin assembly stationary installation, 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 labor intensity of operating personnel, also improved work efficiency.
