Description

TECHNICAL FIELD

[0001] The application belongs to the field of power distribution network equipment, and particularly relates to an environment-friendly and energy-saving type gas-filled cabinet for a power distribution network. BACKGROUND

[0002] With the continuous deepening of the construction and reconstruction of the power distribution network, the energy-saving and environment-friendly type gas-filled cabinet has been widely applied in the power distribution network system due to its compact structure, non-influence by adverse environment, high reliability and other advantages. The gas-filled cabinet seals the high-voltage live parts in the gas tank filled with insulating gas, significantly improves the safety and stability of the equipment, and is suitable for various occasions such as urban power grids, rail transit, industrial and mining enterprises and the like. However, in the actual transportation, installation and operation and maintenance process, the existing gas-filled cabinet has obvious defects in mobility and stability.

[0003] Most of the existing fixed installation type gas-filled cabinets are not integrated with special moving devices. After the equipment arrives at the site, external heavy equipment such as forklifts and cranes needs to be used for carrying and positioning, which greatly affects the construction efficiency. In order to facilitate movement, some gas-filled cabinets will be equipped with simple walking wheels at the bottom of the cabinet body. However, the walking wheels are usually directly fixed on the cabinet body, and lack effective locking and stable supporting mechanisms. When the gas-filled cabinet is in place, only relying on the walking wheel support will cause the cabinet body to easily shake or even shift when subjected to external force, which threatens the safe and stable operation of the precise components in the cabinet. Moreover, the existing gas-filled cabinets with walking wheels have a permanent exposed structure of the walking wheels, which cannot be retracted after the equipment is in place. The tires or bearings of the walking wheels are not designed to withstand long-term static load, and long-term compression may cause rubber aging and bearing deformation, which has a risk of failure and reduces the stability of the gas-filled cabinet as a whole. SUMMARY

[0019] The principles and features of the application will be described below in conjunction with the drawings, which are only used to explain the application and do not limit the scope of use of the application.

[0020] As Figures 1-4As shown, this invention proposes an environmentally friendly and energy-saving gas-insulated switchgear for power distribution networks, comprising a switchgear body 1, a housing 2 fixedly mounted at the bottom of the switchgear body 1, a lifting frame movable vertically inside the housing 2, two sliding blocks 6 slidably mounted on the lifting frame, and two telescopic plates 4 on the same side fixed to the same sliding block 6. Specifically, the lifting frame includes left and right side plates 52 and four sliding rods 51 in the middle. The sliding rods 51 are horizontally fixed between the two side plates 52 in the left and right directions, and the four sliding rods 51 are fixed at the four corners of the square side plates 52. The sliding blocks 6 are horizontally slidably fitted onto the sliding rods 51; a screw 71 is installed in the middle between the two side plates 52, and a motor 72 is installed on the right side plate 52 and powered by the screw 71. Vertical slide rails 26 are respectively provided on the left and right inner walls of the housing 2, and the lifting frame is vertically slidably mounted on the slide rails 26 on both sides. Two octagonal strip holes 21 are symmetrically provided on the front and rear side walls of the housing 2. Guide blocks 61 are fixedly provided at the front and rear ends of the moving block 6. The two guide blocks 61 on the same moving block 6 are slidably engaged in the two corresponding strip holes 21 at the front and rear of the housing 2.

[0021] The four sliding rods 51 on the lifting frame of this application can effectively limit the left and right sliding of the moving block 6, significantly improving the stability of the moving block 6. When the two moving blocks 6 are driven to move away synchronously from side to side by the synchronous lateral movement component, the guide block 61 on the moving block 6, guided by the octagonal strip hole 21, will drive the entire lifting frame to move downward, while the telescopic plate 4 connected to the moving block 6 will move downward and extend outward, thereby realizing the extension and downward support of the walking wheel 3. After the air cabinet is installed in place, the synchronous lateral movement component drives the two moving blocks 6 to move closer to each other, which can drive the lifting frame to move upward and cause the telescopic plate 4 to move upward and retract into the box, thereby realizing the retraction of the walking wheel 3.

[0022] A synchronous lateral movement assembly is also horizontally installed on the lifting frame. This assembly is connected to two moving blocks 6 and is used to drive the two moving blocks 6 to move closer or further away synchronously. Specifically, the synchronous lateral movement assembly includes a screw 71 and a motor 72. The screw 71 is horizontally installed in the middle of the two side plates 52 of the lifting frame. A second vertical hole 25 is vertically opened on the side of the housing 2. The motor 72 is located outside the housing 2 and is installed on the right side plate 52 through the second vertical hole 25. The end of the screw 71 is poweredly connected to the motor 72. The left and right sides of the screw 71 are respectively provided with positive and negative threads, and the two moving blocks 6 are respectively threaded onto the positive and negative threads on both sides of the screw 71.

[0023] When the screw 71 is rotated by the motor 72, the two moving blocks 6 can be moved steadily away from or close to each other under the limiting action of the slide bar 51, thereby significantly improving the movement stability of the moving blocks 6, the telescopic plate 4 and the traveling wheel 3.

[0024] Two wheels 3 are respectively provided on the left and right sides of the housing 2, one in front and one behind. The four wheels 3 are mounted on corresponding telescopic plates 4. Specifically, the telescopic plate 4 includes a vertical plate 41 and a base plate 42. One end of the vertical plate 41 is fixed to the end face of the moving block 6, and the other end extends out of the housing 2 through the first vertical hole 24 and is perpendicularly fixed to the base plate 42. The base plates 42 on the two vertical plates 41 on the same side are respectively positioned on opposite sides of the vertical plates 41, and the wheels 3 are mounted on the base plates 42. The opposite positioning of the two base plates 42 increases the wheelbase between the two wheels 3, improving movement stability.

[0025] The left and right sides of the housing 2 are provided with recessed storage slots 23 for storing the wheels 3; the first vertical hole 24 and the second vertical hole 25 are both opened on the inner side wall of the storage slots 23. When the telescopic plate 4 of this application is retracted, it can store the wheels 3 in the storage slots 23 on both sides, thereby avoiding the wheels 3 being exposed and affecting the power distribution network operation site.

[0026] Multiple support seats 22 are fixedly installed at the bottom of the box 2. After the air cabinet is installed in place, the two side wheels 3 are stored in the storage slots 23. The air cabinet is then supported by the support seats 22 below, which avoids the wheels 3 being exposed to the outside for a long time and bearing the weight of the air cabinet, thus significantly improving the support stability of the air cabinet.

[0027] In use, the invention utilizes a motor 72 to drive the screw 71 to rotate, causing the two moving blocks 6 to move in tandem. With the sliding cooperation between the strip hole 21 and the guide block 61, the lifting frame can be moved downwards, thereby causing the telescopic plate 4 to extend on both sides and move downwards. This allows the four traveling wheels 3 on both sides to be stably supported on the ground, lifting the entire device off the ground, thus greatly facilitating the movement and transport of the gas cabinet. Once the gas cabinet is in place, the motor 72 drives the screw 71 to rotate, causing the lifting frame to move upwards. The telescopic plate 4 moves upwards and retracts into the box, thereby causing the traveling wheels 3 on both sides to move upwards and approach the box body 2 until it retracts into the storage slot 23. At this time, the support base 22 at the bottom of the box body 2 supports the entire device, thus significantly improving the installation stability of the gas cabinet.
