[0002] In the process of power system operation and maintenance, power test devices are often used for insulation testing, relay protection verification and performance testing of various power equipment (such as switch cabinets, transformers, distribution boxes, etc.). In order to ensure the safety and accuracy of the test process, the equipment to be tested needs to be reliably fixed on the test platform to prevent equipment from falling, wiring from loosening or even accidents due to vibration, movement or accidental touching.
[0003] However, the existing power test devices generally lack effective upper limit and dynamic fixing structure, and most of them only rely on the base to be placed or simple lateral buckling for positioning.

DETAILED DESCRIPTION
[0016] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.
[0017] The power test device for power maintenance according to the embodiments of the present application is described below in combination with the drawings.
[0018] Figure 1 is a structural schematic diagram of the power test device for power maintenance according to an embodiment of the present application.
[0019] As Figures 1-3 shown, the power test device for power maintenance according to the embodiments of the present application comprises a main body 10, a rack 20, a lifting frame 30 and a fixing mechanism 40, wherein the lifting frame 30 is installed on the main body 10; the rack 20 is threadedly arranged on the lifting frame 30; the fixing mechanism 40 comprises a plurality of electric telescopic rods 401 fixedly installed on the lifting frame 30; the output ends of the plurality of electric telescopic rods 401 are fixedly installed with a cover plate 402; the bottom surface of the cover plate 402 is provided with a fixed frame 403; a plurality of telescopic cylinders 404 are fixedly installed in the fixed frame 403; an extension rod 405 is slidably connected in each of the plurality of telescopic cylinders 404; a push spring 406 is fixedly connected in each of the plurality of telescopic cylinders 404; and a moving mechanism 407 is arranged on the cover plate 402.
[0020] It should be noted that in the initial state, the electric telescopic rod 401 is in the extended state, and when it is necessary to fix the power equipment, the output end of the electric telescopic rod 401 is controlled to move downward, thereby driving the fixed frame 403 to move downward.
[0021] In an embodiment of the present application, as Figures 1-3 shown, the width of the fixed frame 403 is the same as the width of the rack 20, and one end of each of the plurality of push springs 406 is fixedly connected with the corresponding extension rod 405.
[0022] In one embodiment of the present application, as shown in Figures 1-3 The plurality of telescopic cylinders 404 are evenly distributed in the fixed frame 403, and the length of the plurality of telescopic cylinders 404 is the same as the length of the fixed frame 403.
[0023] Specifically, in actual operation, the power equipment needs to be moved by the main body 10, and the power equipment is directly placed on the placing rack 20, which will shake during movement, affecting the stability of the power equipment.
[0024] When it is necessary to fix the power equipment, first place the power equipment on the placing rack 20, and after placing, control the output end of the electric telescopic rod 401 to move downward by controlling the switch. The output end of the electric telescopic rod 401 moving downward will drive the cover plate 402 to move downward, and the cover plate 402 moving downward will drive the fixed frame 403 and the telescopic cylinder 404 to move downward. When part of the extension rods 405 in the plurality of telescopic cylinders 404 move downward and contact the main body 10, they will be extruded by the main body 10, causing the extension rods 405 in contact with the main body 10 to retract into the corresponding telescopic cylinder 404, and the extension rods 405 around the main body 10 can protect the main body 10 around the top of the main body 10, thereby achieving limiting the top of the main body 10.
[0025] The electric telescopic rod drives the cover plate 402, the fixed frame 403 and the telescopic cylinder 404 to move downward synchronously, causing the extension rods in the plurality of telescopic cylinders 404 to move downward and contact the main body of the power equipment. When part of the extension rods 405 touches the top of the equipment, they automatically retract under the extrusion of the main body, and the remaining extension rods 405 that have not contacted or have contacted less continue to press down and adhere to the equipment around, achieving multi-point limiting and flexible covering of the top and side of the main body. This effectively solves the problem of traditional equipment without upper fixing structure, which is prone to shaking and collision during movement, significantly improving the stability and safety during movement. At the same time, the plurality of extension rods can be independently telescopic, suitable for power equipment of different shapes and sizes, with good versatility and self-adaptability, enhancing the fixing effect and improving the application range of the equipment.
[0026] In one embodiment of the present application, as shown in Figure 2 The moving mechanism 407 includes two support plates 4071 installed on the bottom surface of the cover plate 402; the two support plates 4071 are threadedly provided with moving rods 4072; and one end of the two moving rods 4072 close to the fixed frame 403 is fixedly installed with a moving motor 4073.
[0027] In one embodiment of the present application, as shown in Figure 2 The two moving motors 4073 are oppositely installed on the fixed frame 403, and the output ends of the two moving motors 4073 are fixedly connected with the corresponding moving rods 4072.
[0028] It should be noted that since the two moving rods 4072 on the fixed frame 403 support the fixed frame 403, when the fixed frame 403 is moved, the moving directions of the two moving rods 4072 need to be ensured to be the same, and therefore the two moving motors 4073 need to be ensured to be able to drive the moving rods 4072 to move in the same direction.
[0029] In an embodiment of the present application, as shown in Figure 2 The fixed frame 403 is in sliding connection with the cover plate 402, and the lengths of the two moving rods 4072 are greater than the length of the cover plate 402.
[0030] Specifically, in actual operation, the positions of the power equipment placed on the placing rack 20 are different, so that the fixed frame 403 at the same position cannot fix the power equipment at different positions.
[0031] When it is necessary to fix the power equipment at different positions, first, the output end of the moving motor 4073 is controlled to rotate by controlling the switch, the rotation of the output end of the moving motor 4073 drives the moving rod 4072 to rotate, and since the moving rod 4072 is in threaded connection with the support plate 4071, the moving rod 4072 can move when the moving rod 4072 rotates, the movement of the moving rod 4072 drives the fixed frame 403 to move, and then the fixed frame 403 can be moved to the upper side of the power equipment at different positions, so as to facilitate the fixing of the power equipment at different positions.
[0032] By controlling the moving motor to drive the moving rod to rotate, the fixed frame is driven to move in the horizontal direction accurately by the threaded cooperation of the moving rod and the support plate. When it is necessary to fix the power equipment at different positions, the position of the fixed frame can be automatically adjusted to be accurately moved to the upper side of the target equipment, without manual adjustment or reassembly, which significantly improves the flexibility and applicability of the equipment.
[0033] In summary, the power test device for power maintenance in the embodiment of the present application drives the cover plate, the fixed frame and the telescopic cylinder to move downward synchronously by the electric telescopic rod, so that the extension rods in the plurality of telescopic cylinders move downward and contact the main body of the power equipment. When part of the extension rods touch the top of the equipment, they are automatically retracted under the extrusion of the main body, while the remaining extension rods that are not in contact or have less contact continue to press down and adhere to the equipment, achieving multi-point limiting and flexible covering of the top and the side of the main body. The problem that the equipment is easily shaken and collided during movement due to the lack of upper fixing structure in the traditional device is effectively solved, and the stability and safety during movement are significantly improved. At the same time, the plurality of telescopic rods can be independently telescoped, which is suitable for power equipment with different shapes and sizes, has good universality and self-adaptability, enhances the fixing effect, and improves the application range of the equipment.
