Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel testing equipment, and in particular to a physical load testing device for solar cell modules. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). A laminate is installed on the outside of the PV panel, primarily composed of tempered glass. This laminate protects the main power generation components (such as the solar cells), and its selection is subject to requirements; it must have high light transmittance (generally above 91%) and undergo ultra-clear tempering treatment.

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

[0004] In existing technologies, such as a physical load photovoltaic module testing device (CN202111104091.X), ice particles falling from a height are used to hit the photovoltaic panel, thereby simulating the gravitational impact of hail on the photovoltaic panel and testing the physical impact load of hail on the photovoltaic panel. However, the consumption of ice particles is relatively large, the tilt angle of the photovoltaic panel is relatively singular, and it is not possible to conduct a comprehensive physical impact test on the photovoltaic panel. At the same time, the speed of the falling ice particles is somewhat different from the speed of ice particles under natural weather conditions, thus failing to accurately simulate the state of hail impacting the photovoltaic panel under natural conditions.

[0036] Example 1

[0037] See Figures 1 to 8 The present invention provides a physical load testing device for solar cell modules, including a base frame 1, a clamping frame 2 for placing solar panels 4 at one end of the base frame 1, and an ice hockey launcher 3 for simulating hail falling at the other end;

[0038] The clamping frame 2 includes a base 201 fixedly mounted on the base frame 1, a rotating plate 202 rotatably mounted in the middle of the base 201, two vertical plates 203 parallelly mounted on the rotating plate 202, and a clamping plate 204 rotatably mounted on the vertical plates 203. The clamping plate 204 is "H" shaped and a solar panel 4 is placed on the clamping plate 204. A clamp 205 for clamping the solar photovoltaic panel is fixedly mounted at each of the four corners of the clamping plate 204.

[0039] The clamp 205 includes a mounting base 2051 fixedly mounted on the clamping plate 204. The mounting base 2051 is "T" shaped, and the horizontal part of the mounting base 2051 is fixedly connected to the clamping plate 204.

[0040] A first connecting rod 2052 is rotatably mounted on the vertical part of the mounting base 2051. A clamping arm 2053 is rotatably mounted on the movable end of the first connecting rod 2052. The middle part of the clamping arm 2053 is rotatably connected to the first connecting rod 2052. A second connecting rod 2054 is rotatably mounted on one end of the clamping arm 2053, and a pad is fixedly mounted on the other end. The pad is made of rubber and can prevent the clamping arm 2053 from damaging the solar panel 4. An adjusting block 2055 is rotatably mounted on the movable end of the second connecting rod 2054. The adjusting block 2055 is slidably connected to the vertical part of the mounting base 2051.

[0041] A third link 2056 is rotatably mounted on the adjusting block 2055, and the third link 2056 is rotatably connected to the middle of the first link 2052;

[0042] It also includes a controller for adjusting the position of the adjustment block 2055.

[0043] The controller includes a handle 2057 rotatably mounted on the horizontal part of the mounting base 2051, a control link 2058 rotatably mounted in the middle of the handle 2057, and the movable end of the control link 2058 rotatably connected to the adjusting block 2055.

[0044] A handle sleeve is fixedly installed on the outside of the handle 2057.

[0045] When the operator needs to clamp the solar panel 4, he can rotate the handle 2057. The handle 2057 drives the adjusting block 2055 to move upward through the control link 2058. Under the combined action of the first link 2052, the second link 2054 and the third link 2056, the adjusting block 2055 drives the clamping arm 2053 to clamp the solar panel 4.

[0046] When it is necessary to release the solar panel 4, turn the handle 2057 in the opposite direction to move the adjusting block 2055 downward. At this time, the clamping arm 2053 is above the mounting base 2051, reducing the volume of the clamp 205. When the operator picks up and puts down the solar panel 4, the clamp 205 will not affect the picking up and putting down of the solar panel 4.

[0047] A vertical guide rail is fixedly installed on the vertical part of the mounting base 2051, and a sliding groove is opened on the side wall of the adjusting block 2055. The adjusting block 2055 is slidably connected to the guide rail through the sliding groove.

[0048] A tilting worm gear 2041 is fixedly installed on the clamping plate 204. The tilting worm gear 2041 is coaxial with the rotating shaft 2045 of the clamping plate 204. One side of the tilting worm gear 2041 meshes with a tilting worm 2042. The tilting worm 2042 is coaxial with the rotating plate 202. A driven bevel tooth 2043 is fixedly installed at the lower end of the tilting worm 2042. A driving bevel tooth 2044 meshes with the driven bevel tooth 2043. A rotating shaft 2045 is fixedly installed on one side of the driving bevel tooth 2044. The rotating shaft 2045 extends to one end of the base frame 1 and is coaxially fixed with a driven gear 206.

[0049] A rotating worm gear 2021 is coaxially fixed at the lower end of the rotating plate 202. One side of the rotating worm gear 2021 meshes with a rotating worm 2022. The rotating worm 2022 is rotatably connected to the base 201. A transmission shaft 2023 is coaxially fixed at one end of the rotating worm 2022. The transmission shaft 2023 extends to one end of the base frame 1 and is coaxially fixed with a driven gear 206.

[0050] A support plate 101 is fixedly installed on the base frame 1. An arc-shaped guide groove 102 is opened on the support plate 101. A slider is slidably installed in the guide groove 102. A drive gear 103 is rotatably installed on the slider. The drive gear 103 meshes with one of the driven gears 206.

[0051] A driven sprocket 104 is coaxially fixed on the drive gear 103, and a drive sprocket 105 is rotatably mounted on the base frame 1. The drive sprocket 105 and the driven sprocket 104 are connected by a chain 106. The rotation shaft 2045 of the drive sprocket 105 is coaxially arranged with the axis of the guide groove 102.

[0052] A handwheel 107 is coaxially fixed on the drive sprocket 105.

[0053] When the driving gear 103 meshes with the driven gear 206 coaxial with the rotating worm 2022, the operator turns the handwheel 107. 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 2021 to rotate. At this time, the operator can adjust the horizontal tilt angle of the solar panel 4 by turning the handwheel 107.

[0054] When the driving gear 103 meshes with another driven gear 206, the operator turns the handwheel 107. Under the action of the driving sprocket 105 and the driven sprocket 104, the driving gear 103 drives the driven gear 206 to rotate. Under the action of the driving bevel gear 2044 and the driven bevel gear 2043, the rotating worm gear 2041 is driven to rotate. At this time, the operator can adjust the rotation angle of the solar panel 4 by turning the handwheel 107.

[0055] The operator can adjust the tilt angle of the solar panel 4 from one side of the transmitter 3, reducing the time required for the operator to adjust the solar panel 4 back and forth and improving the convenience of adjusting the solar panel 4.

[0056] A slide rod 108 is fixedly installed on the base frame 1, and an adjuster 109 is slidably installed on the slide rod 108. The adjuster 109 includes a housing 1010 slidably connected to the slide rod 108. A fixed handle 1012 is fixedly installed on one side of the housing 1010. A clamping rod 1011 is rotatably installed inside the housing 1010. A through hole is opened in the middle of the clamping rod 1011. The slide rod 108 slides in the through hole. A clamping handle 1013 is fixedly installed at one end of the clamping rod 1011.

[0057] A spring is provided between the clamping rod 1011 and the housing 1010. When not in use, the clamping rod 1011 is inclined and the position of the housing 1010 is restricted by the friction between the through hole and the slide rod 108. The spring can ensure that the clamping rod 1011 is always in contact with the slide rod 108.

[0058] When the operator needs to move the housing 1010, press the clamping handle 1013. At this time, a gap appears between the clamping rod 1011 and the slide rod 108. The operator can move the adjuster 109 up and down by moving the housing 1010. After the position is moved, release the clamping handle 1013, and the housing 1010 is fixed on the slide rod 108. The adjustment process is convenient and quick.

[0059] An adjusting rod 1014 is rotatably mounted on one side of the outer casing 1010. One end of the adjusting rod 1014 is rotatably connected to the outer casing 1010, and the other end is rotatably connected to the slider.

[0060] The slider position can be adjusted by adjusting the regulator 109, which controls the engagement of the drive gear 103 with one of the driven gears 206. The operator can switch the drive gear 103 while standing, which improves the convenience of adjustment.

[0061] The hockey launcher 3 includes a launch tube 301 fixedly mounted 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 provided between the gas storage cylinder and the launch tube 301.

[0062] Artificial hailstones are placed in launch tube 301, valve 302 is opened to release compressed air from the air storage tank, and the compressed air pushes the hailstones to impact the solar panel 4, simulating the speed at which hailstones fall naturally. The launch speed of the hailstones can be adjusted by regulating the air pressure in the air storage tank.

[0063] When using this invention, the operator first moves the adjuster 109 to engage the driven gear 206 connected to the rotating shaft 2045 with the driving gear 103. By rotating the handwheel 107, the clamping plate 204 is brought to a horizontal position, making it easier for the operator to pick up and put down the solar panel 4. When the solar panel 4 is placed on the clamping plate 204, the four clamps 205 are used to clamp the four corners of the solar panel 4. Then, the tilt angle of the solar panel 4 is adjusted by rotating the handwheel.

[0064] By engaging the drive gear 103 and the driven gear 206 fixed to the drive shaft 2023, the horizontal tilt angle of the solar panel 4 can be adjusted by rotating the handwheel 17. This can realistically simulate the angle between the solar panel 4 and the hailstones falling, improving the realism of the device's simulation of hailstones falling naturally and further enhancing the accuracy of the device's simulation test.

[0065] Artificial hailstones are placed in launch tube 301, valve 302 is opened to release compressed air from the air storage tank, and the compressed air pushes the hailstones to impact the solar panel 4, simulating the speed at which hailstones fall naturally. The launch speed of the hailstones can be adjusted by regulating the air pressure in the air storage tank.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
