Description
Technical field
The present invention relates to a kind of solar photovoltaic assembly checkout equipment, verify that especially solar photovoltaic assembly stands the equipment of hail impact ability.
Background technology
Solar photovoltaic assembly is installed in the open air, should be able to bear hail impact to a certain degree.Standards such as GB/T9535, IEC61215, IEC61730-2, UL 1703 have all proposed the hail testing requirements.
The early stage test method that adopts comprises catapult or spring emission, generally adopt the gases at high pressure emission now, but common way is to allow gases at high pressure directly promote ice hockey.Because ice hockey melts inevitably, it can not accurate control with the tolerance clearance of power valve, and therefore the speed of at every turn launching differs greatly, and the repeatability of test is not good.
Summary of the invention
The energy that the invention provides a kind of gases at high pressure can continue to discharge reposefully and have the solar photovoltaic assembly hail testing machine of good repeatability.
To achieve these goals, the present invention adopts following technical scheme:
It comprises that an air compressor and utilizes the test chassis of gases at high pressure emission ice hockey; Link to each other by first high-pressure air pipe that has reduction valve between described air compressor and the high pressure tank of test on the chassis; Described high pressure tank is provided with a tensimeter; High pressure tank connects a power valve to photovoltaic module emission ice hockey by second high-pressure air pipe that has solenoid valve; Described solenoid valve is triggered by a controller that is installed on the test chassis, the exit of described power valve is provided with a light electric tachometer, the gases at high pressure that described air compressor produces, enter high pressure tank through high-pressure air pipe, after controller triggering solenoid valve, gases at high pressure enter power valve, and gases at high pressure promote piston and quicken to advance, piston promotes ice hockey to be launched to tested solar photovoltaic assembly, and the initial velocity of emission is monitored with light electric tachometer.
Preferably, install a little gas-holder on the described power valve additional, enter the gases at high pressure of power valve through solenoid valve from high pressure tank, be stored in the little gas-holder temporarily, avoid solenoid valve to open moment power valve internal pressure and sharply change and cause gas to leak, and the energy that makes gases at high pressure is along with the preceding of piston and then continue to discharge reposefully.
Preferably, comprise a connecting rod in the described power valve; The connecting rod front end connects a carrying and releases the piston of ice hockey, and piston comprises a bowl-type bullet holder; Rod rear end connects cushion pad and nut, adjustable link length.
Owing to adopted said structure, the velocity-stabilization of solar photovoltaic assembly hail testing machine emission ice hockey of the present invention is controlled.The design that gases at high pressure promote piston has improved the interior impermeability of power valve, make the normal thawing of ice hockey not influence the piston motion effect, therefore guarantee that the speed of at every turn launching ice hockey is consistent, thereby and make the stressed even fragmentation of avoiding of ice hockey, to guarantee the validity of impact test.

The object of the invention, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As shown in Figure 1, present embodiment it comprise that an air compressor 1 and that produces gases at high pressure utilizes the test chassis 15 of gases at high pressure emission ice hockey; Link to each other by first high-pressure air pipe 2 that has reduction valve 3 between described air compressor 1 and the high pressure tank 4 of test on the chassis 15; Described high pressure tank 4 is provided with a tensimeter 5; High pressure tank connects a power valve 9 to photovoltaic module emission ice hockey by second high-pressure air pipe that has solenoid valve 7; Described solenoid valve is triggered by a controller 7 that is installed on the test chassis; The exit of described power valve 9 is provided with a light electric tachometer 14, and the gases at high pressure that described air compressor 1 produces enter high pressure tank 4 through high-pressure air pipe 2; After controller 7 triggering solenoid valves 6, gases at high pressure enter power valve 9, and gases at high pressure promote piston 11 and quicken to advance, and piston promotes ice hockey 16 to be launched to tested solar photovoltaic assembly 17, and the initial velocity of emission is monitored with light electric tachometer 14.
In order better to keep the steady release of gases at high pressure, install a little gas-holder 8 on the described power valve additional, enter the gases at high pressure of power valve 9 through solenoid valve 7 from high pressure tank 4, be stored in the little gas-holder 8 temporarily, avoid solenoid valve 7 to open moment power valve 9 internal pressures and sharply change and cause gas to leak, and the energy that makes gases at high pressure is along with the preceding of piston and then continue to discharge reposefully.
In order further to keep ice hockey steadily to discharge, comprise a connecting rod 10 in the described power valve 9; Connecting rod 10 front ends connect a carrying and release the piston 11 of ice hockey, and piston 11 surfaces comprise a bowl-type bullet holder 12; Rod rear end connects cushion pad 13 and nut, adjustable link length.
The concrete course of work is as follows:
The gases at high pressure that air compressor 1 produces enter high pressure tank 4 through high-pressure air pipe 2; After controller 7 triggering solenoid valves 6, gases at high pressure enter power valve 9, and wherein a part of gas is the process buffering in little gas-holder 8; Gases at high pressure promote piston 11 and quicken to advance, till cushion pad and nut 13 are run into power valve 9.The bowl-type bullet holder 12 of piston nose promotes ice hockey 16 and launches, and the initial velocity of emission is monitored with light electric tachometer 14.
