Description

Technical Field

[0001] The present invention relates to the field of photovoltaic panel testing equipment, and particularly to a physical load testing equipment for solar cell modules. Background Art

[0002] A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight, and is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). A laminate is provided on the outer side of the photovoltaic panel, and the laminate is mainly composed of tempered glass. Its function is to protect the power generation body (such as the battery chip), and there are requirements for its selection. The light transmittance must be high (generally above 91%); ultra-white tempering treatment is required.

[0003] Photovoltaic panels are mainly installed in outdoor environments, so they will face various complex weather conditions, such as strong winds, hail and other bad weather. Therefore, the encapsulation quality of photovoltaic modules determines the service life and reliability of photovoltaic panels.

[0004] In the prior art, such as a physical load photovoltaic module testing equipment (CN202111104091.X), ice particles dropped from a high place are used to hit the photovoltaic panel, so as to simulate the gravitational impact when hail drops on the photovoltaic panel and test the physical impact load of hail on the photovoltaic panel. However, the consumption of ice particles is large, the inclination angle of the photovoltaic panel is relatively single, and the anti-physical impact test of the photovoltaic panel cannot be carried out in all directions. At the same time, there is a certain gap between the speed of the dropped ice particles and the speed of ice particles in natural weather, so the state of hail impacting the photovoltaic panel in a natural state cannot be well simulated.

The solar panel 4 is placed on the clamping plate 204. A clamp 205 for clamping the solar photovoltaic panel is fixedly provided at each of the four corners of the clamping plate 204.

[0030] The clamp 205 includes a mounting seat 2051 fixedly provided on the clamping plate 204. The mounting seat 2051 is in an "丄" shape.

The movable end of the control connecting rod 2058 is rotatably connected to the adjusting block 2055.

[0032] A handle sleeve is fixedly provided on the outer side of the handle 2057.

[0033] When the operator needs to clamp the solar panel 4, the handle 2057 is turned, and the handle 2057 drives the adjustment block 2055 to move upward through the control connecting rod 2058. The adjustment block 2055 drives the clamping arm 2053 to clamp the solar panel 4 under the joint action of the first connecting rod 2052, the second connecting rod 2054 and the third connecting rod 2056.

[0034] When the solar panel 4 needs to be released, the handle 2057 is rotated in the opposite direction to move the adjustment block 2055 downward. At this time, the clamping arm 2053 is located above the mounting seat 2051, reducing the volume of the clamp 205. When the operator takes or places the solar panel 4, the clamp 205 will not affect the taking or placing of the solar panel 4.

[0035] A vertical guide rail is fixedly arranged on the vertical portion of the mounting seat 2051 , and a sliding groove is provided on the side wall of the adjusting block 2055 , and the adjusting block 2055 is slidably connected to the guide rail through the sliding groove.

[0038] A support plate 101 is fixedly arranged on the bottom frame 1, and an arc-shaped guide groove 102 is provided on the support plate 101. A slider is slidably arranged in the guide groove 102, and a driving gear 103 is rotatably arranged on the slider. The driving gear 103 is meshed with one of the driven gears 206; A driven sprocket 104 is coaxially fixedly arranged on the driving gear 103, a driving sprocket 105 is rotatably arranged on the bottom frame 1, and the driving sprocket 105 and the driven sprocket 104 are connected by a chain 106; a rotating shaft 2045 of the driving sprocket 105 is coaxially arranged with the axis of the guide groove 102; A hand wheel 107 is coaxially fixedly arranged on the driving sprocket 105 .

[0039] When the driving gear 103 is meshed with the driven gear 206 coaxial with the rotating worm 2022, the operator turns the hand wheel 107, and under the action of the driving sprocket 105 and the driven sprocket 104, the driving gear 103 drives the driven gear 206 to rotate, thereby driving the rotating worm gear 2021 to rotate. At this time, the operator adjusts the horizontal tilt angle of the solar panel 4 by turning the hand wheel 107.

[0040] When the driving gear 103 is meshed with another driven gear 206, the operator turns the hand wheel 107, and under the action of the driving sprocket 105 and the driven sprocket 104, the driving gear 103 drives the driven gear 206 to rotate, and under the action of the driving bevel gear 2044 and the driven bevel gear 2043, the flip worm gear 2041 is driven to rotate. At this time, the operator adjusts the flip angle of the solar panel 4 by turning the hand wheel 107.

[0041] The operator can adjust the tilt angle of the solar panel 4 on one side of the transmitter 3, which reduces the time required for the operator to adjust the solar panel 4 back and forth and improves the convenience of adjusting the solar panel 4.

[0042] A slide bar 108 is fixedly arranged on the bottom frame 1, and an adjuster 109 is slidably arranged on the slide bar 108.

The clamping rod 1011 is arranged at an angle when not in use. The position of the housing 1010 is limited by the friction between the through hole and the slide bar 108. The spring can ensure that the clamping rod 1011 is always in contact with the slide bar 108. When the operator needs to move the shell 1010, the clamping handle 1013 is pressed. At this time, a gap appears between the clamping rod 1011 and the sliding rod 108. The operator can move the shell 1010 to move the adjuster 109 up and down. After the position movement is completed, the clamping handle 1013 is released, and the shell 1010 is fixed on the sliding rod 108. The adjustment process is convenient and quick.

[0044] The position of the slider can be adjusted by the regulator 109 to control the driving gear 103 to mesh with one of the driven gears 206 . The operator can switch the driving gear 103 while standing, which improves the convenience of adjustment.

[0045] The ice ball launcher 3 includes a launch tube 301 fixedly arranged on the base frame 1 , one end of the launch tube 301 faces the solar panel 4 , and the other end is connected to the gas storage cylinder. A valve 302 is arranged between the gas storage cylinder and the launch tube 301 .

[0046] Place an artificial hail ball in the launching tube 301, open the valve 302, release the compressed air in the air cylinder, and push the hail ball through the compressed air to impact the solar panel 4, simulating the speed of hail falling naturally. The launching speed of hail can be adjusted by adjusting the air pressure in the air cylinder.

[0047] When the present invention is used, the operator first moves the regulator 109 to mesh the driving gear 103 with the driven gear 206 connected to the rotating shaft 2045, and turns the hand wheel 107 to make the clamping plate 204 horizontal, which is convenient for the operator to take and place the solar panel 4. When the solar panel 4 is placed on the clamping plate 204, four clamps 205 are used to clamp the four corners of the solar panel 4 respectively, and then the pitch angle of the solar panel 4 is adjusted by turning the hand wheel; By meshing the driving gear 103 with the driven gear 206 fixed to the transmission shaft 2023 and rotating the hand wheel 17, the horizontal tilt angle of the solar panel 4 can be adjusted, and the angle between the hail and the solar panel 4 when falling can be realistically simulated, thereby improving the authenticity of the device in simulating the natural falling of hail and further improving the accuracy of the device simulation test.

[0048] Place an artificial hail ball in the launching tube 301, open the valve 302, release the compressed air in the air cylinder, and push the hail ball through the compressed air to impact the solar panel 4, simulating the speed of hail falling naturally.
