Description

Technical Field

[0001] The utility model belongs to the field of vanadium battery testing, and in particular relates to a vanadium battery safety testing protection device. Background Art

[0002] Vanadium batteries, or all-vanadium redox flow batteries, are redox batteries in which the active material is a circulating, flowing liquid. Their cost is similar to that of lead-acid batteries, and they can be manufactured into megawatt-class battery packs, providing high-power, long-term energy. Therefore, vanadium batteries offer unmatched cost-performance advantages over lithium-ion and nickel-metal hydride batteries in large-scale energy storage. Their simple production process, affordability, and excellent electrical performance make them more competitive than fuel cells, which are complex and expensive to manufacture. They offer a wide range of applications, both in large-scale energy storage and as a power source for electric vehicles.

[0003] During battery production, various functions must be tested. Testing involves testing various functions, typically examining the durability of vanadium batteries and their performance under extreme conditions. Therefore, during testing, there is a high risk of vanadium batteries being damaged, potentially polluting the environment and threatening the safety of operators. Currently, there are no specialized protective devices designed to isolate vanadium batteries from operators to ensure their safety and prevent accidents. Utility Model Content

[0004] The utility model aims to provide a vanadium battery safety test protection device to solve the problem that the vanadium battery is damaged during the detection process, thereby threatening the personal safety of operators.

[0006] The working principle and beneficial effects of the present scheme are as follows: when not in use, the movable door and the fixed door seal the front side of the box; when in use, the motor of the gear is started to drive the gear to rotate, so that the rack meshing with the gear moves to one side of the fixed door; the movement of the rack drives the movable wheel mechanism below to slide in the through groove; due to the unique shape of the through groove, the movable wheel mechanism moves away from the opening of the box, and then moves to one side of the fixed door, so that the movable wheel mechanism drives the movable door to slowly move away from the opening of the box first, so that the movable door is separated from the fixed door, and then the movable door slides into the rear of the fixed door, and then the movable door slides to one side of the fixed door to expose the inside of the box, and then the vanadium battery can be placed in the box, and then the motor is reversed to drive the movable door away from the fixed door, so that the side wall of the movable door and the side wall of the fixed door are connected to seal the inside of the box, and the operator can test the vanadium battery; the device places the vanadium battery in the box, and then uses the door opening mechanism to seal the vanadium battery, so that the vanadium battery is wrapped in the box, avoiding the explosion of the vanadium battery during testing and increasing the safety factor of the operator.

[0007] Further, the movable wheel mechanism is provided with a moving block, the top end of the moving block is rotationally connected with the rack, the bottom of the moving block is rotationally connected with the movable door, and two bottom wheels are rotationally connected with the bottom of the moving block. A ring of bosses is arranged around the position close to the bottom of the through groove, side wheels are rotationally connected with the two sides of the moving block, the side wheels are slidingly connected with the two sides of the through groove and the top end of the bosses, and the bottom wheels are slidingly connected in the interior of the bosses. When the rack moves, the movable wheel mechanism below is driven to move, so that the side wheels and the bottom wheels of the movable wheel mechanism can ensure the stable operation of the movable door when deflection occurs, multi-wheel operation reduces the resistance during movement, and the movable door can be more easily opened.

[0008] Further, the bottom of the box is fixedly connected with a sliding rail, and the top end of the sliding rail is slidingly connected with a placing plate. When in use, the placing plate can be slid out of the box, the vanadium battery can be placed on the placing plate, and then the placing plate can be slid into the box, thereby reducing the difficulty of carrying the vanadium battery.

[0009] Further, a plurality of ventilation holes are formed in the side of the box relative to the door opening mechanism. The ventilation holes can dissipate heat inside when the vanadium battery is detected.

[0010] Further, a wire slot is formed in the rear side of the box. When the vanadium battery is detected, a plurality of external wires can be passed out of the wire slot, avoiding the accumulation of the wires in the box and reducing the safety hazard.

[0011] Further, an exhaust fan is arranged on the rear side of the box. The exhaust fan can exhaust the heat generated during the detection of the vanadium battery, ventilate the air inside, reduce the heat during the detection of the vanadium battery, and reduce the safety hazard during the detection.
