Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module testing tools, and specifically relates to a photovoltaic IV testing tool. Background Technique

[0002] A photovoltaic module, namely a solar cell module. Since the output voltage of a single solar cell is relatively low, and the electrodes of the unpackaged battery are prone to falling off due to environmental influence, a certain number of single cells must be sealed into a photovoltaic module in series and parallel to avoid corrosion of the battery electrodes and interconnections. When performing an IV test on a photovoltaic module, it is necessary to clamp and fix the photovoltaic module.

[0003] The internal and external structures of the existing photovoltaic module testing tools are relatively simple. They cannot perform automatic coaxial clamping on the photovoltaic module well, are not convenient for adjusting the height of the device, and cannot provide good protection for the photovoltaic module during clamping to avoid wear caused by direct contact between the photovoltaic module and the clamping head, and cannot well meet people's usage requirements.

[0004] For example, a photovoltaic module IV testing tool disclosed in Chinese Patent CN212435645U, through the settings of a clamping head and a groove, is beneficial for clamping and fixing the photovoltaic panel, and can improve the stability of the photovoltaic panel during testing. The setting of the rubber pad is beneficial for protecting the photovoltaic panel and avoiding wear between the edge of the photovoltaic panel and the clamping head during clamping, thereby causing damage to the photovoltaic panel.

[0005] However, when testing a larger photovoltaic module with this device, it is necessary to lift the photovoltaic panel and then horizontally move it into the clamping head and then clamp it by the clamping head, which increases the labor intensity of the staff during the horizontal movement of the photovoltaic panel and is not convenient to use.

[0006] Therefore, we urgently need to provide a photovoltaic IV testing tool. Content of the Utility Model

[0007] The purpose of the utility model is to provide a photovoltaic IV testing tool to solve the problem of increasing the labor intensity of the staff during the horizontal movement of the photovoltaic panel and being inconvenient to use as proposed in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A photovoltaic IV testing tool, including a housing, and a clamping device is arranged inside the housing.

[0009] The clamping device includes a moving unit and a clamping unit. The moving unit is arranged on the top of the housing, and the clamping unit is arranged inside the housing.

[0010] The mobile unit includes a telescopic member, a fixed frame, rollers, mounting rods, a support plate, support rods, and a disc. The telescopic members are fixedly installed on the left and right sides of the bottom inside the housing. The fixed frame is fixedly installed on the top of the telescopic member. The rollers are fixedly installed inside the fixed frame. The mounting rods are fixedly installed around the top inside the housing. The support plate is fixedly installed at the bottom of the four mounting rods. The support rods are fixedly installed on the top of the support plate and located between adjacent rollers. The disc is fixedly installed on the top of the support rod.

[0011] Preferably, the clamping unit includes a fixed block, a motor, a connecting rod, a limiting rod, and a clamping plate. The fixed blocks are fixedly installed at the front and rear ends of the top inside the housing. The motor is fixedly installed on the front of the front fixed block. One end of the connecting rod is fixedly installed on the output end of the motor, and the other end is rotatably connected to the inside of the rear fixed block. The limiting rod is fixedly installed on the adjacent side of the front and rear fixed blocks above the connecting rod. The lower ends of the clamping plates are installed on the outer sides of the front and rear ends of the connecting rod and the limiting rod.

[0012] Preferably, a rectangular groove equal in size to the fixed frame is provided on the upper surface of the housing. The rollers are equidistantly distributed inside the fixed frame. By starting the telescopic member to push the fixed frame upward, the height of the fixed frame is made higher than that of the disc. Then, one end of the photovoltaic panel to be tested is placed on the top of the rollers, and the photovoltaic panel is pushed in cooperation with the rollers to move the photovoltaic panel to the right until it reaches a suitable position, eliminating the need for workers to lift the photovoltaic panel and then move it, reducing the labor intensity of the workers.

[0013] Preferably, the diameter of the disc is smaller than the distance between adjacent rollers to prevent the fixed frame from colliding with the disc during the up and down movement.

[0014] Preferably, external threads in opposite directions are provided at the front and rear ends of the connecting rod. The lower ends of the front and rear clamping plates are threadedly connected to the outside of the connecting rod. By starting the motor to drive the connecting rod to rotate, when the connecting rod rotates and is threadedly connected to the front and rear clamping plates, the clamping plates move along the limiting rod to clamp the photovoltaic panel.

[0015] Preferably, the clamping units are symmetrically distributed on the left and right sides of the top inside the housing. By providing two clamping units at the left and right ends of the photovoltaic panel, the clamping stability of the photovoltaic panel is improved.

[0016] Preferably, rubber pads are fixedly installed on the adjacent sides of the front and rear clamping plates to prevent the clamping plates from scratching the side of the photovoltaic panel when clamping the photovoltaic panel.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. The photovoltaic IV test tooling, by setting a moving unit, starts the telescopic member to push the fixed frame upward, making the height of the fixed frame higher than that of the disc. Then, one end of the photovoltaic panel to be tested is placed on the top of the roller, and then the photovoltaic panel is pushed to cooperate with the roller to move the photovoltaic panel to the right until the photovoltaic panel moves to a suitable position. Then, the telescopic member is started to drive the fixed frame and the photovoltaic panel to move downward. When the fixed frame is lower than the disc, the bottom of the photovoltaic panel abuts against the top of the disc, so as to support the photovoltaic panel through the support rod and the disc, without the need for staff to lift the photovoltaic panel and then move the photovoltaic panel, reducing the labor intensity of the staff and solving the problem of increasing the labor intensity of the staff and inconvenient use in the background technology during the horizontal movement of the photovoltaic panel.

[0019] 2. The photovoltaic IV test tooling, through the clamping unit, starts the motor to drive the connecting rod to rotate. When the connecting rod rotates, it is threadedly connected to the front and rear two clamping plates, so that the clamping plates move along the limiting rod to clamp the photovoltaic panel, with high clamping efficiency.
