TECHNICAL FIELD
[0001] The present application relates to the technical field of detection, in particular to a performance detection device for a power distribution cabinet body. BACKGROUND
[0002] The power distribution cabinet is a key device for collecting, distributing and controlling electric energy in the power system, and undertakes the important task of safely and stably delivering electric energy from the transformer to various types of electrical equipment. It not only has electrical protection functions such as overload and short circuit, effectively ensuring the safe operation of the circuit, but also usually has a corrosion-resistant coating on the surface of the cabinet body to provide protection for the cabinet body in complex environments and improve the reliability and service life of the equipment. The power distribution cabinet often operates in complex environments, and after mass production of the power distribution cabinet, the cabinet body needs to be sampled and tested, such as pressure and corrosion resistance detection. Pressure detection can verify the structural strength of the cabinet body to ensure that it does not deform during transportation, installation or accidental stress, and maintain the safety and protection level of internal components. Corrosion resistance detection evaluates the protection ability of the cabinet body in humid, salt spray and other corrosive environments, and optimizes the corrosion prevention process through corrosion resistance detection.
[0003] In the existing corrosion resistance detection process of the power distribution cabinet body, the method of spraying acid mist (hydrochloric acid mist, sulfuric acid mist or nitric acid mist) is usually used to simulate harsh corrosive environments. By observing and recording the corrosion changes on the surface of the cabinet body over time, the performance of the corrosion-resistant coating and the corrosion resistance of the cabinet body material are evaluated. However, acid mist has strong volatility and can easily spread into the surrounding air during spraying and detection, not only polluting the laboratory or workshop environment, but also causing irritation and harm to the respiratory system, skin and eyes of the operators. Long-term exposure can cause chronic health problems and affect the occupational safety of workers. After the corrosion resistance detection is completed, the corroded cabinet body needs to be handled, but the acid substances in the acid mist are often still present on the surface of the cabinet body before it is moved and transferred, and the operators are easily injured by acid or other chemical hazards when they come into contact with it, forming a serious secondary safety hazard.

In this process, the one side telescopic rod 48 is shortened to drive the rotating plate 47 to rotate, the rotating plate 47 drives the other side telescopic rod 48 to shorten, so that the other side telescopic rod 48 drives the other side sliding plate 43 to slide along the fixed seat 42 to approach the one side sliding plate 43, thereby realizing that the left and right sliding plates 43 simultaneously slide along the fixed seat 42 to approach each other. When the front and rear second rollers 510 abut against the outer surface of the cabinet body, the left and right sliding plates 43 continue to move to approach each other, the reaction force of the cabinet body drives the second roller 510 to rotate the shaft, the reset torsion spring 491 is deformed, the first roller 51 is driven to move to approach the outer surface of the cabinet body on the two sides by the rotation of the shaft, so that the first roller 51 pushes the cabinet body to approach the center of the first detection box 1, and the four corners of the cabinet body are located between the first roller 51 and the second roller 510, thereby realizing the positioning of the four corners of the cabinet body. The pressure block 40 is driven to move to extrude the outer surface of the cabinet body by the hydraulic rod 39, the real-time pressure of the cabinet body by the pressure block 40 is detected by the pressure sensor 41, and the real-time pressure is recorded. When the cabinet body deforms, the pressure is the maximum bearing pressure of the cabinet body, so that the pressure of the cabinet body can be detected, and the initial distance between the cabinet body and the left and right pressure blocks 40 is ensured to be the same by the clamping assembly, so that the cabinet body remains symmetrical during the stress process, thereby obtaining more accurate and reliable compression performance data, ensuring the scientific nature of the pressure detection, and when the pressure detection is completed, the one side sliding plate 43 is driven to slide away from the other side sliding plate 43 by the elongation of the piston rod of the cylinder 45, the one side telescopic rod 48 is stretched, the other side telescopic rod 48 is stretched by the reverse rotation of the rotating plate 47, the other side sliding plate 43 is reset, the shaft is reversed by the reset of the reset torsion spring 491, and then the cabinet body can be taken out from the first detection box 1.
