Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module testing technology, specifically to a portable photovoltaic module pressure testing device. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are the core devices that convert solar energy into electrical energy. They are composed of multiple solar cells assembled through an encapsulation process and are the smallest effective power generation unit in a photovoltaic power generation system. To ensure the long-term reliability and safety of photovoltaic modules, stress testing of photovoltaic modules is required.

[0003] Existing photovoltaic module pressure testing devices have a fixed structure, which prevents the hydraulic cylinder position from being adjusted arbitrarily. This results in a fixed pressure detection range, making it impossible to perform distributed or concentrated pressure testing on photovoltaic panels, thus limiting their effectiveness. Furthermore, these devices are fixed in a specific location, making them inconvenient to carry around. Therefore, it is essential to design a portable photovoltaic module pressure testing device. Utility Model Content

[0004] The purpose of this invention is to provide a portable photovoltaic module pressure testing device, which solves the problem in related technologies that it is impossible to conduct decentralized or centralized pressure testing on photovoltaic panels during use, resulting in limited effectiveness.

[0005] The technical solution of this utility model is as follows:

[0006] A portable photovoltaic module pressure testing device includes a test frame. Columns are screwed to the bottom four sides of the test frame. Slots are formed on the top four sides of the test frame, extending into the columns. A top plate is located above the top of the test frame, and connecting rods are screwed to the bottom four sides of the top plate. The bottom of four connecting rods are respectively inserted into four slots. Sliding grooves are formed on the inner walls of both ends of the top plate, and a first support rod is welded between two sliding grooves. Two second support rods are slidably installed between the two sliding grooves, located on either side of the first support rod. Sliding blocks are equidistantly installed on both the first and second support rods, and hydraulic cylinders are screwed to the bottom of the sliding blocks. Pressure pads are screwed to the telescopic ends of the hydraulic cylinders. Several insertion holes are equidistantly formed on both sides of the bottom of the sliding grooves. Damping telescopic rods are screwed to both ends of the bottom of the second support rods, and connecting plates are screwed to the telescopic ends of the damping telescopic rods. An insertion rod is welded to the other end of the top of the connecting plate, and one top end of the insertion rod is inserted into an insertion hole.

[0007] Preferably, spring telescopic rods are screwed to both sides of the slider on the first support rod, and the telescopic ends of the spring telescopic rods are screwed to and fixed to the slider on the second support rod. A hydraulic system is provided on the top of the top plate, and the hydraulic cylinder is electrically connected to the hydraulic system.

[0008] Preferably, a plurality of limiting grooves are equally spaced on one side of the outer wall of the connecting rod, and magnets are screwed around the outer wall of the test frame, with a limiting rod inserted into the center of the magnet. One end of the limiting rod passes through the slot and extends into the limiting groove.

[0009] Preferably, the magnet has notches on both sides, the limiting rod is made of ferritic stainless steel, and the other end of the limiting rod is magnetically connected to the magnet.

[0010] Preferably, a support frame is welded to the bottom of the inner wall of the test frame, a push rod is screwed to the outer wall of one end of the test frame, a base plate is provided at the bottom of the test frame, and the bottom end of the column is welded and fixed to the top of the base plate. All four sides of the bottom of the base plate are screwed with universal wheels with brakes.

[0011] Preferably, a fixing plate is welded to the outer wall of one end of the top plate, and a support plate is welded to the outer wall of the other end of the test frame. A screw is threadedly installed in the center of the support plate, the top end of the screw is inserted into the bottom of the fixing plate, and a hand crank is screwed to the bottom end of the screw.

[0012] Preferably, the top end face of the base plate is provided with a movable groove, and a support plate is installed inside the movable groove via a ball bearing slide rail. A handle is screwed to one side of the support plate, and several sandbags are stacked on top of the support plate.

[0013] Preferably, a limiting block is installed on one side of the base plate via a rotating shaft, and the top end of the limiting block is located on the outside of the support plate.

[0014] The beneficial effects of this utility model are:

[0015] The hydraulic system drives the hydraulic cylinders downwards, allowing pressure pads to press against the photovoltaic panels for dynamic load testing. By pushing the second support rod within the chute and moving the slider, the distance between the hydraulic cylinders can be adjusted, facilitating testing at different locations on the photovoltaic panels. This enables both concentrated and dispersed pressure testing. Pushing the connecting plate upwards inserts the insertion rod into the insertion hole, fixing the position of the second support rod. A spring telescopic rod connects adjacent sliders, allowing the hydraulic cylinders on the first and second support rods to move synchronously. After the dynamic load test, the top plate is raised again, allowing sandbags to be removed and placed on the photovoltaic panels for static load testing, thus improving the equipment's usability.

[0016] By pushing the push rod, the equipment can be moved under the action of the braked casters, making it easy to carry around. By pressing the brake pads on the braked casters, the tires can be locked to prevent the equipment from moving. By rotating the limit block, the pallet can be restricted within the movable groove to prevent it from slipping out during movement, thus improving the safety of the equipment. By inserting the limit rod into the limit groove, the position of the connecting rod can be fixed, improving the support effect on the top plate. The limit rod can be magnetically fixed using a magnet to prevent it from coming out. At the same time, the notch on the magnet can be easily separated from the limit rod.

The hydraulic cylinder 10 can move synchronously. The hydraulic system 17 is used to drive the hydraulic cylinder 10. Several limiting grooves 18 are equally spaced on one side of the outer wall of the connecting rod 5. Magnets 19 are screwed around the outer wall of the test frame 1, and a limiting rod 20 is inserted into the center of the magnet 19. One end of the limiting rod 20 passes through the slot 3 and extends into the limiting groove 18. By inserting the limiting rod 20 into the limiting groove 18, the position of the connecting rod 5 can be fixed. Notches are provided on both sides of the magnet 19. The limiting rod 20 is made of ferritic stainless steel, and the other end of the limiting rod 20 is magnetically connected to the magnet 19.
