Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module testing equipment, and specifically to photovoltaic module testing fixtures. Background Technology

[0002] With the rapid development of the photovoltaic industry, the quality inspection of photovoltaic modules has become increasingly important. As a key piece of equipment in the photovoltaic module testing process, the performance of test fixtures directly affects the accuracy and reliability of test results.

[0003] However, most existing photovoltaic module testing fixtures can only achieve single-direction adjustment during use, and cannot adjust the posture of photovoltaic modules from multiple angles and directions according to different testing scenarios. This results in limited testing scenarios and makes it difficult to fully simulate the actual application environment. In addition, existing fixtures mostly use rigid clamping to fix photovoltaic modules, which can easily cause squeezing damage to the edges of photovoltaic modules during clamping, especially for thin and fragile new photovoltaic modules, where the risk of damage is even higher. At the same time, the test wiring part of existing fixtures lacks effective organization and protection structures, resulting in messy wires during testing. This not only affects the convenience of operation, but may also affect the accuracy of test data due to wire wear, poor contact, and other problems. Therefore, we propose a photovoltaic module testing fixture. Utility Model Content

[0004] In view of the problems existing in the above-mentioned photovoltaic module testing fixtures, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a photovoltaic module testing fixture, which solves the problems of existing photovoltaic module testing fixtures, which mostly only allow for single-direction adjustment during use and cannot adjust the photovoltaic module's posture from multiple angles and directions according to different testing scenarios. This results in limited testing scenarios and makes it difficult to fully simulate the actual application environment. Furthermore, existing fixtures mostly use rigid clamping to fix photovoltaic modules, which can easily cause squeezing damage to the edges of photovoltaic modules during clamping, especially for thin and fragile new photovoltaic modules, where the risk of damage is even higher. At the same time, the test wiring part of existing fixtures lacks an effective organization and protection structure, resulting in messy wires during testing. This not only affects the convenience of operation but may also affect the accuracy of test data due to wire wear, poor contact, and other problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photovoltaic module testing fixture includes a base, a rotating seat, and a clamping frame. A fixed sleeve is fixedly installed on the top of the base. A threaded rod is slidably provided inside the fixed sleeve. A rotating shaft is fixedly installed on the top of the threaded rod. A rotating seat is rotatably provided on the top of the rotating shaft. A fixed seat is fixedly installed on the top of the rotating seat. A ring-shaped locking sleeve is provided inside the fixed seat. A universal ball is provided inside the ring-shaped locking sleeve. A clamping frame is fixedly installed on the top of the universal ball. A fixed clamping plate is fixedly installed on one side of the clamping frame. A movable clamping plate is slidably provided on the other side of the clamping frame. An adjusting screw is threadedly connected to the other side of the clamping frame. The other end of the adjusting screw is rotatably connected to one side of the movable clamping plate.

[0008] Preferably, a fixing block is fixedly installed on one side of the clamping frame, a slide rail is fixedly installed on one end surface of the fixing block, a movable block is slidably provided inside the slide rail, wire holes are provided on the opposite side of the fixing block and the movable block, a first locking bolt is threadedly connected to one side of the slide rail, and the other end of the first locking bolt is rotatably connected to one side of the movable block.

[0009] Preferably, an angle scale is fixedly mounted on the surface of the rotating shaft, a rotating sleeve is fixedly mounted on the bottom of the rotating seat, the rotating sleeve is fitted on the top of the rotating shaft, and a second locking bolt is threaded to one side of the rotating sleeve. A laser pointer is fixedly mounted on the bottom of the rotating seat, and the laser pointer is located at the top of the angle scale.

[0010] Preferably, both the fixed clamp and the movable clamp are provided with elastic protective pads on opposite sides.

[0011] Preferably, the top of the fixed sleeve is rotatably provided with an internal threaded ring, which is threadedly connected to the surface of the threaded rod.

[0012] Preferably, an anti-slip pad is fixedly installed on the bottom of the base.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model utilizes a height adjustment structure composed of a fixed sleeve, a threaded rod, and an internal threaded ring. Rotating the internal threaded ring drives the threaded rod to rise and fall along the fixed sleeve, precisely adjusting the component's testing height. Simultaneously, the horizontal rotation structure of the rotating shaft, rotating seat, and rotating sleeve, in conjunction with an angle scale and laser pointer, can precisely control the rotating seat to drive the component to rotate around the vertical axis, simulating different illumination angles. Furthermore, through the universal adjustment structure of the fixed seat, the ring-shaped locking sleeve, and the universal ball, the universal ball can rotate arbitrarily. After adjusting the component's tilt angle, tightening the ring-shaped locking sleeve provides stable locking. This comprehensively simulates solar illumination scenarios at different latitudes and times of day, solving the limitations of existing fixture testing scenarios.

[0015] 2. This utility model emphasizes component protection in its clamping structure design. Elastic protective pads are provided on opposite sides of both the fixed and movable clamping plates. The elastic material effectively buffers the squeezing force during clamping. Simultaneously, the movable clamping plate is driven to slide by an adjusting screw, allowing flexible control of the clamping force according to the component size. This avoids squeezing damage to the edges of thin, fragile new photovoltaic modules caused by rigid clamping, reducing component loss costs during testing and solving the problem of easy component damage from existing rigid clamping. Furthermore, the device is equipped with an angle scale and laser pointer, allowing for intuitive reading of the horizontal rotation angle and ensuring angle adjustment accuracy. Height adjustment relies on the threaded transmission of the internal threaded ring and threaded rod, ensuring a smooth adjustment process and precise height control. Each adjustment structure is secured with bolts or locking sleeves, providing a secure lock and preventing displacement. Additionally, the anti-slip pad at the bottom of the base increases friction with the ground, preventing slippage during testing. The overall structure is simple to operate and highly stable, meeting the needs of actual testing work. Attached Figure Description

[0026] This utility model photovoltaic module testing fixture has an angle scale 18 fixedly installed on the surface of the rotating shaft 6, a rotating sleeve 19 fixedly installed on the bottom of the rotating seat 2, the rotating sleeve 19 being fitted onto the top of the rotating shaft 6, and a second locking bolt 20 being threadedly connected to one side of the rotating sleeve 19. A laser pointer 21 is fixedly installed on the bottom of the rotating seat 2, and the laser pointer 21 is located on top of the angle scale 18, which facilitates precise adjustment of the angle of the photovoltaic module.

[0027] The photovoltaic module testing fixture of this utility model has elastic protective pads 22 on the opposite sides of the fixed clamping plate 10 and the movable clamping plate 11 to prevent damage to the photovoltaic module.

[0028] The photovoltaic module testing fixture of this utility model has an internal threaded ring 23 rotatably provided on the top of the fixed sleeve 4. The internal threaded ring 23 is threadedly connected to the surface of the threaded rod 5, which facilitates the adjustment of the height of the photovoltaic module.

[0029] The photovoltaic module testing fixture of this utility model has an anti-slip pad 24 fixedly installed on the bottom of the base 1, which can increase the friction between the base 1 and the ground, improve the stability of the fixture during the testing process, and prevent the fixture from sliding.

[0030] In use, in the initial state, the base 1 is stably placed on the test platform by the bottom anti-slip pad 24, the fixing sleeve 4 is vertically fixed on the top of the base 1, the threaded rod 5 is slidably inserted into the fixing sleeve 4, the rotating seat 2 is sleeved on the top of the rotating shaft 6 by the rotating sleeve 19, the universal ball 9 is embedded in the ring-type locking sleeve 8 in the fixing seat 7, the clamping frame 3 is connected to the rotating seat 2 by the universal ball 9, the movable clamping plate 11 is slidably assembled in the clamping frame 3, the movable block 15 of the wire organizing structure is initially in one end of the slide rail 14, then the photovoltaic module to be tested is placed in the clamping frame 3, so that one side of it is in contact with the elastic protective pad 22 of the fixing clamping plate 10, and then the adjusting screw 12 is rotated to adjust the screw... The rod 12 is pushed along the threaded hole on the side wall of the clamping frame 3, pushing the movable clamping plate 11 to slide towards the fixed clamping plate 10 until the elastic protective pad 22 of the movable clamping plate 11 is tightly attached to the other side of the component. The adjustment screw 12 is then stopped, completing the flexible clamping and fixing of the component to avoid pressure damage to the edge of the component. Then, the internal threaded ring 23 at the top of the fixed sleeve 4 is rotated. The internal threaded ring 23 engages with the threaded rod 5, driving the threaded rod 5 to slide up and down along the inner wall of the fixed sleeve 4, causing the rotating seat 2, the clamping frame 3 and the component to rise and fall synchronously until the target test height is reached. The internal threaded ring 23 is then stopped, and the threaded rod 5 maintains a stable height due to the self-locking of the thread. The second locking screw on the side wall of the rotating sleeve 19 is then loosened. Bolt 20 pushes the rotating seat 2 to rotate around the rotating shaft 6. The laser pointer 21 at the bottom of the rotating seat 2 indicates the rotation angle on the angle scale 18. When the target angle is reached, tighten the second locking bolt 20.

The universal ball 9 is fixed in position by the friction between the inner wall of the locking sleeve and the surface of the universal ball 9, ensuring the stability of the assembly's tilt posture. According to the number and diameter of the wires required for the test, slide the movable block 15 in the slide rail 14 to adjust the fixed position. The distance between the fixed block 13 and the movable block 15 allows the wire holes 16 on opposite sides to combine and form a channel for the wires. The test wire is inserted into the combined wire hole 16. The first locking bolt 17 on one side of the slide rail 14 is rotated to push the movable block 15 toward the fixed block 13 until the wire is tightly clamped in the wire hole 16, thus completing the wire arrangement and preventing the wire from shaking or tangling during the test. After the module posture and wire arrangement are completed, the photovoltaic module performance test can be carried out. After the test, the first locking bolt 17 is loosened in sequence to remove the wire, and the adjusting screw 12 is used to loosen the movable clamp 11 to remove the module. Then, the adjustment structures are reset as needed, ready for the next test.
