Description

Technical Field

[0001] The utility model relates to the technical field of single crystal component processing, and more specifically, to a testing device for single crystal components. Background Art

[0002] Monocrystalline modules are one of the core components of solar power generation systems. Specifically, they refer to photovoltaic modules made from monocrystalline silicon rods. Due to the complete lattice arrangement and low defect rate of monocrystalline silicon wafers, the transmission of electrons in the crystal is smoother, reducing energy loss, making the photoelectric conversion efficiency of monocrystalline modules high. They are widely used in various photovoltaic power stations, industrial rooftop photovoltaic projects, and scenarios with high requirements for photovoltaic system performance.

[0003] In order to ensure the performance of single crystal modules in actual use, single crystal modules are usually tested. Current testing equipment, such as Chinese patent application number: CN202122806634.4, "A testing device for single crystal modules", is equipped with a test box, a fan, a metal tube, a temperature control box, a box door, a left clamping plate, a placement table, a right clamping plate, a fluorescent lamp, a heating rod, a coil, a refrigerator, a screw, a stepper motor, a screw block and a temperature sensor, which solves the problems of poor performance of traditional single crystal module testing equipment, inconvenience in clamping and fixing the modules, and inconvenience in adjusting the ambient temperature.

[0004] However, in actual use, solar panels made of single-crystal components are usually placed at an angle to increase the rate of receiving sunlight. The device can only test the performance of single-crystal components at different temperatures, and cannot simulate the actual application environment well to test their waterproof performance and photoelectric conversion performance during rainfall. Therefore, it needs to be improved and optimized. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, the utility model provides a testing device for single crystal components, including a test box 1, a box door 2 is provided on the front side of the test box 1, the test box 1 and the box door 2 are rotatably connected by a hinge 3, and an observation window 4 is provided on the front side of the box door 2;

[0028] A drainage plate 5 is fixedly installed inside the test box 1. Support columns 8 are fixedly installed on the left and right sides of the top of the drainage plate 5. A support plate 10 is rotatably installed between the two groups of support columns 8. A slide groove 11 is opened on the front side of the support plate 10. Slide blocks 13 are movably installed on the left and right sides of the slide groove 11. A screw rod 12 is rotatably installed inside the slide groove 11. The screw rod 12 and the two groups of slide blocks 13 are threadedly connected. A clamping plate 14 is fixedly installed on one end of the slide block 13.

[0029] A movable groove 16 is provided on the rear side of the drainage plate 5, and a screw rod 17 is rotatably installed inside the movable groove 16. A movable block 18 is movably installed inside the movable groove 16. The movable block 18 and the screw rod 17 are threadedly connected. One end of the movable block 18 is rotatably connected to the connecting rod 9, and the other end of the connecting rod 9 is rotatably connected to the support plate 10. A water spray pipe 21 is provided on the top of the test box 1, and a fluorescent lamp 20 is fixedly provided on the top of the test box 1.

[0030] When it is necessary to test the single crystal component, the staff first connects the water inlet 24 and the water supply pipe to each other, and then the staff places the single crystal component on the top of the support plate 10, and makes one end of the single crystal component and the slider 13 abut against each other. At this time, the staff turns the knob 15 to rotate the screw rod 12, and the rotation of the screw rod 12 drives the two sets of sliders 13 threadedly connected to it to move inward, further making the two sets of clamping plates 14 fix the single crystal component. At this time, the staff turns on the fluorescent lamp 20 and starts to test the single crystal component. When it is necessary to simulate a real external rainfall environment, the staff starts the external water pump to make the water pass through the water inlet 24 and be sprayed out by the water pipe 21. The staff can start the motor 19, and the operation of the motor 19 provides power for the rotation of the screw rod 2 17, so that the screw rod 2 17 drives the moving block 18 threadedly connected to it to move, and the moving block 18 moves along the moving groove 16, so that the moving block 18 pushes the connecting rod 9 to move, and further lifts the support plate 10. At this time, the single crystal component is in a tilted state and begins to simulate the external environment during actual use. At this time, the staff can test the waterproof performance and working performance of the single crystal component during rainfall. When the water pipe 21 simulates rainfall, the water source will fall into the water storage tank 6 through the drainage board 5. After the test is completed, the staff can recycle the water source in the water storage tank 6 through the drain outlet 7 for reuse.

[0031] By rotating the knob 15, the rotation of the screw rod 12 drives the two groups of sliders 13 threadedly connected to it to move inward, further making the two groups of clamping plates 14 fix the single crystal component, and then through the operation of the motor 19, the screw rod 2 17 drives the moving block 18 threadedly connected to it to move along the moving groove 16, lifting the support plate 10 to an inclined shape. Compared with the traditional device, this device fixes the single crystal component through two groups of clamping plates 14, and then tilts the support plate 10 through the operation of the motor 19, thereby simulating the actual application environment of the single crystal component, and can effectively detect the working efficiency of the single crystal component in actual use, making the detection function richer and the detection result more in line with reality.

[0032] There are two groups of fluorescent lamps 20, and a water spray pipe 21 is rotatably installed between the two groups of fluorescent lamps 20;

[0033] A bracket 22 is fixedly installed on the rear side wall of the test box 1, and the bracket 22 is rotatably connected to the water spray pipe 21. A gear 23 is fixedly installed on the outer wall of the water spray pipe 21, and a guide groove 25 is fixedly installed below the gear 23. A rack 26 is movably installed inside the guide groove 25, and the rack 26 and the gear 23 are engaged with each other. An electric push rod 27 is fixedly installed on one side of the guide groove 25, and the output shaft of the electric push rod 27 is fixedly connected to the rack 26.

[0034] When the water spray pipe 21 simulates rainfall, the staff can start the electric push rod 27. The operation of the electric push rod 27 will push the rack 26 to move. At this time, the rack 26 moves along the guide groove 25, so that the rack 26 drives the gear 23 threadedly connected to it to rotate. The rotation of the gear 23 drives the water spray pipe 21 to rotate, and the direction of the simulated rainfall of the water spray pipe 21 changes, further enriching the simulated rainfall function of the water spray pipe 21.

[0035] Through the operation of the electric push rod 27, the rack 26 is displaced along the guide groove 25, and the rack 26 further drives the gear 23 threadedly connected to it to rotate. The rotation of the gear 23 drives the water pipe 21 to rotate. At this time, the simulated rainfall direction of the water pipe 21 changes. Compared with the traditional device, this device rotates the water pipe 21 through the operation of the electric push rod 27, further enabling the single crystal component to be tested for rainfall in different directions, and can effectively detect the waterproof performance of the single crystal component, thereby improving the detection accuracy.

[0036] A water storage tank 6 is provided at the bottom of the drainage board 5 , and a drainage port 7 is provided on the outer wall of the test box 1 . The drainage port 7 and the water storage tank 6 are communicated with each other.

[0037] When the water spray pipe 21 simulates rainfall, water will fall into the water storage tank 6 through the drainage plate 5. After the test is completed, the staff can recycle the water in the water storage tank 6 through the drainage port 7 for reuse.

[0038] The threads on the left and right ends of the screw rod 12 are opened in opposite directions and have the same pitch. A knob 15 is rotatably installed on the outer wall of the support plate 10, and the knob 15 is fixedly connected to the screw rod 12.

[0039] Since the threads of the screw rod 12 are opened in different directions, the rotation of the screw rod 12 drives the two sets of sliders 13 threadedly connected thereto to move inward.

[0040] A motor 19 is fixedly mounted on the rear side wall of the test box 1 , and an output shaft of the motor 19 is fixedly connected to the second screw rod 17 .

[0041] The operation of the motor 19 provides power for the rotation of the screw rod 17, so that the screw rod 17 drives the moving block 18 threadedly connected thereto to move.

[0042] A water inlet 24 is fixedly mounted on the rear side of the bracket 22 , and the water inlet 24 is responsible for connecting to a water source.

[0043] By setting up an external water pump, the water supply pipe transports water to the water spray pipe 21 through the water inlet 24 .

[0044] The clamping surfaces of the two sets of clamping plates 14 are fixedly provided with rubber pads, which are responsible for fixing and protecting the single crystal components.

[0045] The working principle and use process of this utility model:

[0046] When it is necessary to test the single crystal component, the staff first connects the water inlet 24 and the water supply pipe to each other, and then the staff places the single crystal component on the top of the support plate 10, and makes one end of the single crystal component and the slider 13 abut against each other. At this time, the staff turns the knob 15 to rotate the screw rod 12, and the rotation of the screw rod 12 drives the two sets of sliders 13 threadedly connected to it to move inward, further making the two sets of clamping plates 14 fix the single crystal component. At this time, the staff turns on the fluorescent lamp 20 and starts to test the single crystal component. When it is necessary to simulate a real external rainfall environment, the staff starts the external water pump to make the water pass through the water inlet 24 and be sprayed out by the water pipe 21. The staff can start the motor 19, and the operation of the motor 19 provides power for the rotation of the screw rod 2 17, so that the screw rod 2 17 drives the moving block 18 threadedly connected to it to move, and the moving block 18 moves along the moving groove 16, so that the moving block 18 pushes the connecting rod 9 to move, and further lifts the support plate 10. At this time, the single crystal component is in a tilted state and begins to simulate the external environment during actual use. At this time, the staff can test the waterproof performance and working performance of the single crystal component during rainfall. When the water pipe 21 simulates rainfall, the water source will fall into the water storage tank 6 through the drainage board 5. After the test is completed, the staff can recycle the water source in the water storage tank 6 through the drain outlet 7 for reuse.

[0047] When the water spray pipe 21 simulates rainfall, the staff can start the electric push rod 27. The operation of the electric push rod 27 will push the rack 26 to move. At this time, the rack 26 moves along the guide groove 25, so that the rack 26 drives the gear 23 threadedly connected to it to rotate. The rotation of the gear 23 drives the water spray pipe 21 to rotate, and the direction of the simulated rainfall of the water spray pipe 21 changes, further enriching the simulated rainfall function of the water spray pipe 21.
