Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a high-voltage switchgear that is easy to assemble. Background Technology

[0002] A switchgear is an electrical device. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear, and have high-voltage busbars, such as power plants. Some also have underfrequency load shedding to protect the main equipment.

[0003] Utility model patent CN214227541U discloses a high-voltage switchgear device that is easy to assemble, including a housing, a heat dissipation device, and an assembly device. The heat dissipation device includes an electric push rod installed at the top of the housing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution:

[0026] Please see Figures 1 to 6 A high-voltage switchgear that is easy to assemble includes a cabinet 1, a height adjustment mechanism 2 is provided inside the cabinet 1, a front and rear adjustment mechanism 3 is provided on the surface of the height adjustment mechanism 2, an air inlet slot 4 is provided below the surface of the cabinet 1, and an exhaust fan 5 is fixed on the top of the cabinet 1.

[0027] The height adjustment mechanism 2 includes two guide plates 201. The guide plates 201 are fixed to the inner wall of the cabinet 1. A front mounting shell 202 is slidably connected to the surface of the guide plates 201. A rear mounting shell 203 is provided on the rear side of the front mounting shell 202. A shell 204 is fixed to the surface of the front mounting shell 202. A spring 205 is fixed to the inner wall of the shell 204. A trapezoidal block 206 is fixed to one end of the spring 205. Multiple trapezoidal grooves 207 are opened on the surface of the guide plates 201 to accommodate the trapezoidal blocks 206. An extension plate 209 is fixed to the bottom of the shell 204. A shank screw 210 is threaded through the surface of the extension plate 209. A pin block 211 is fixed to one end of the shank screw 210. A pin hole 212 is opened on the surface of the guide plates 201 to accommodate the pin block 211. A combination plate 208 is fixed between the left and right shells 204.

[0028] With the above technical solution, when adjusting the height, the movable combination plate 208, the front mounting shell 202 and the rear mounting shell 203 can slide along the surface of the guide plate 201. The spring 205 pushes the trapezoidal block 206 into the trapezoidal groove 207 of the guide plate 201 to achieve the initial height locking and guiding effect. Through the trapezoidal structure design, the pin block 211 can be automatically guided to one side of the trapezoidal groove 207 with the cooperation of the trapezoidal block 206 and the trapezoidal groove 207 to achieve stage height positioning. Then, the shank screw 210 can be rotated to insert the pin block 211 into the pin hole 212 to further fix the position and enhance the structural rigidity. With this design, the height adjustment of the combination plate 208 can be completed quickly, saving the time of accurately aligning the pin hole 212 and improving the assembly efficiency.

[0029] A telescopic rod 214 is provided inside the spring 205. One end of the telescopic rod 214 is fixedly connected to the surface of the trapezoidal block 206, and the other end of the telescopic rod 214 is fixedly connected to the inner wall of the housing 204.

[0030] Through the above technical solution, the telescopic rod 214 restricts the compression direction of the spring 205, ensuring that the trapezoidal block 206 is embedded in the trapezoidal groove 207 in a straight line, and avoiding the trapezoidal block 206 from getting stuck due to the spring 205 being skewed.

[0031] One end of the pin block 211 has a semi-circular structure design, and the edge of the pin hole 212 has a chamfered structure design.

[0032] With the above technical solution, when the shank screw 210 rotates, the semi-circular end of the pin block 211 contacts the chamfered hole, achieving smooth insertion. The combination of the two improves the smoothness of the locking operation and reduces the assembly difficulty.

[0033] Two assembly blocks 213 are fixed to the surfaces of both the front mounting shell 202 and the rear mounting shell 203. The surfaces of the assembly blocks 213 are provided with mounting holes. The front mounting shell 202 and the rear mounting shell 203 are detachably connected by using bolts passing through the mounting holes.

[0034] Through the above technical solution, the front mounting shell 202 can be disassembled and assembled with the rear mounting shell 203, so that the combination plate 208 can drive the front mounting shell 202 to be removed from the surface of the guide plate 201, and the operator can set up several combination plates 208 on the surface of the guide plate 201 as needed.

[0035] The front-to-back adjustment mechanism 3 includes a first guide shell 301 and a second guide shell 302. There are two first guide shells 301 and four second guide shells 302. The surface of the rear second guide shell 302 is fixedly connected to the surface of the combination plate 208. Two first mounting shafts 303 are fixedly fixed to the surface of the first guide shell 301. Two first connecting plates 304 are rotatably connected to the surface of the first mounting shafts 303. A secondary sliding groove 305 is formed on the surface of the second guide shell 302, and a main sliding groove 306 is formed on the surface of the first guide shell 301. A first slide rod 307 is rotatably connected to the surface of the connecting plate 304. The first slide rod 307 is slidably connected to the surface of the secondary slide groove 305. Two second mounting shafts 308 are fixed to the surface of the second guide shell 302. A second connecting plate 309 is rotatably connected to the surface of the second mounting shaft 308. A second slide rod 310 is rotatably connected to the surface of the second connecting plate 309. The second slide rod 310 is slidably connected to the surface of the main slide groove 306. A mounting plate 311 is fixed to the surface of the front second guide shell 302. An equipment mounting bracket 312 is fixed to the surface of the mounting plate 311.

[0036] Through the above technical solution, when the second guide shell 302 is activated, the first guide shell 301 and the second guide shell 302 are linked together, causing the first connecting plate 304 to drive the first slide rod 307 to slide along the secondary slide groove 305, and the second connecting plate 309 to drive the second slide rod 310 to slide along the main slide groove 306, pushing the mounting plate 311 and the equipment mounting frame 312 to move back and forth. The multi-level slide groove and the linkage realize the linear adjustment of the equipment mounting frame 312, expand the flexibility of the equipment layout, and allow the equipment mounting frame 312 to move to the front position inside the cabinet 1, so that the operator can install the equipment more conveniently and it is more suitable for precision assembly operations in narrow spaces.

[0037] The surface of the second slide rod 310 is threaded, and a wing nut 313 is threadedly connected to the surface of the second slide rod 310.

[0038] Through the above technical solution, after the butterfly nut 313 is tightened, it presses against the second connecting plate 309 and the first guide shell 301, restricting the displacement of the second slide rod 310 in the main slide groove 306, thereby achieving the positioning effect of the mounting plate 311 after front and rear adjustment.

[0039] The second slide bar 310 located on the inner surface of the first guide shell 301 and the first slide bar 307 located on the inner surface of the second guide shell 302 are both fixed with anti-detachment limiting blocks 314.

[0040] Through the above technical solution, the anti-detachment limiting block 314 prevents the first slide rod 307 and the second slide rod 310 from sliding excessively out of the slide groove, thus avoiding loss of adjustment control.

[0041] Its working principle is as follows: Cabinet 1 achieves segmented vertical adjustment of the equipment through height adjustment mechanism 2: When adjusting the height of mounting plate 311, front mounting shell 202 and rear mounting shell 203 slide along guide plate 201, spring 205 pushes trapezoidal block 206 into trapezoidal groove 207 for initial locking and position guidance, ensuring that one end of the shank screw 210 is located on one side of pin hole 212, saving time for precise alignment. The shank screw 210 drives pin block 211 to insert into pin hole 212 for further reinforcement, completing the height adjustment of mounting plate 311. When the mounting plate 311 is in the front and back position, the movable mounting plate 311, the first connecting plate 304 drives the first sliding rod 307 to move along the secondary sliding groove 305, the second connecting plate 309 slides in the main sliding groove 306 through the second sliding rod 310, driving the mounting plate 311 and the equipment mounting frame 312 to move back and forth, the butterfly nut 313 locks the second sliding rod 310 to fix the position, realizing the adjustment of the front and back position of the mounting plate 311, thus making it easier to install equipment in a small space. The bottom air inlet slot 4 of the cabinet 1 and the top exhaust fan 5 form a forced heat dissipation air duct to ensure the temperature control of the internal equipment.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
