Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, and specifically relates to a high-security switch cabinet. Background Technology

[0002] A switchgear is an electrical device. Its main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components inside a switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protection devices.

[0003] Currently, the support at the bottom of existing switchgear is mainly divided into two types: fixed support legs and movable pulleys. Fixed support legs provide stable support but are inconvenient to move, while movable pulleys provide convenient movement but unstable support. Existing switchgear lacks the ability to combine both functions simultaneously, which leads to problems such as inconvenient movement or unstable support in existing switchgear.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a high-safety switchgear.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a high-safety switch cabinet that can solve the problem that existing switch cabinets cannot simultaneously achieve both convenient movement and stable support.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figures 1 to 9 As shown, a high-security switch cabinet in one embodiment of the present invention includes: a main frame 1 and a support device 2.

[0034] As shown in the figure, a cabinet door 102 is rotatably mounted on the main frame 1, and a handle 104 is rotatably mounted on the cabinet door 102. A handle groove 105 adapted to the handle 104 is carved on the main frame 1. When it is necessary to close the cabinet door 102 on the main frame 1, the handle 104 is rotated to lock the handle 104 into the handle groove 105, thereby locking the cabinet door 102 on the main frame 1. When it is necessary to open the cabinet door 102, the handle 104 is rotated to rotate the handle 104 out of the handle groove 105, and then the cabinet door 102 is opened by pulling the handle 104.

[0035] like Figures 1 to 4 As shown, cover plates 101 are installed on multiple side walls of the main frame 1. Several cover plates 101 have ventilation holes 103. The cover plates 101 serve a protective function and facilitate disassembly, which is beneficial for future maintenance of the equipment inside the main frame 1. The ventilation holes 103 primarily function to dissipate heat. A snap-fit ​​groove 106 is carved into the side wall of the handle groove 105, through which the handle 104 is snapped out of the handle groove 105.

[0036] like Figures 1 to 4 As shown, a locking block 107 is installed on the side wall of the handle groove 105, and a locking groove 110 adapted to the locking block 107 is carved on the handle 104. By inserting the locking block 107 into the locking groove 110, the handle 104 is locked in the handle groove 105, thereby locking the cabinet door 102 onto the main frame 1. A pair of springs 108 are installed between the locking block 107 and the inner wall of the main frame 1. A push plate 109 is fixed to the outside of the main frame 1 for the locking block 107. The elastic force of the springs 108 is used to push the locking block 107 into the locking groove 110, and the push plate 109 is used to drive the locking block 107 out of the locking groove 110.

[0037] like Figures 5 to 9 As shown, the support device 2 is installed inside a pair of side walls of the main frame 1. The support device 2 includes two pairs of fixed bearing seats 201. The two pairs of fixed bearing seats 201 are respectively fixed inside a pair of side walls of the main frame 1. A first support arm 202 and a second support arm 203 are rotatably mounted on a pair of fixed bearing seats 201. A second connecting rod 205 and a pair of first connecting rods 204 are respectively fixed to the ends of the first support arm 202 and the second support arm 203 that are close to each other. The second connecting rod 205 is slidably connected to the pair of first connecting rods 204. A moving wheel 206 is installed on both the first support arm 202 and the second support arm 203. Two pairs of support legs 207 are fixed at the bottom of the main frame 1.

[0038] When the switchgear needs to be moved, the first support arm 202 and the second support arm 203 are rotated around a pair of fixed bearings 201, so that the moving wheel 206 contacts the ground and the switchgear is raised, so that the support leg 207 is disengaged from the ground. Then the switchgear can be moved by the moving wheel 206. After moving to a suitable position, the first support arm 202 and the second support arm 203 are rotated. The first support arm 202 and the second support arm 203 drive the moving wheel 206 to retract into the main frame 1, so that the support leg 207 contacts the ground and provides support. The first support arm 202 or the second support arm 203 can drive the other to rotate through the first connecting rod 204 and the second connecting rod 205.

[0039] like Figures 5 to 9 As shown, a push rod 210 is rotatably mounted above the second support arm 203 and the first support arm 202. By rotating the push rod 210, the push rod 210 pushes the second support arm 203 to rotate downwards around the fixed shaft seat 201. At the same time, the second support arm 203 drives the first support arm 202 to rotate downwards. A pair of slide rails 211 are cut into the push rod 210, and a moving part 212 is slidably mounted in the pair of slide rails 211. A control rod 213 is rotatably mounted on the main frame 1. The control rod 213 is threadedly connected to the moving part 212. A control shaft 214 is slidably mounted on one end of the control rod 213 near the second support arm 203. The control shaft 214 is used to drive the control rod 213 to rotate. When the control rod 213 is rotated, the control rod 213 drives the moving part 212 to move. The movement of the moving part 212 drives the push rod 210 to rotate, while the moving part 212 slides in the slide rails 211.

[0040] like Figures 5 to 9 As shown, a groove 209 is carved on the second connecting rod 205, and a connecting shaft 208 is fixed between a pair of first connecting rods 204. The connecting shaft 208 slides within the groove 209, thereby achieving a sliding connection between the second support arm 203 and the first support arm 202. When the push rod 210 presses the second support arm 203 downward, the second support arm 203 drives the first support arm 202 to move through the connecting shaft 208. A limit groove 216 is carved on the main frame 1. A control head 215 is fixed at one end of the control shaft 214 located within the limit groove 216. The rotation of the control head 215 drives the control shaft 214 to rotate, which in turn drives the control rod 213 to rotate. When rotation is not required, the control head 215 is inserted into the limit groove 216 to prevent the control shaft 214 and the control rod 213 from rotating.

[0041] like Figures 5 to 9As shown, a limit head 219 is fixed to the end of the control shaft 214 away from the control head 215. The limit head 219 is used to limit the control shaft 214 to prevent the control shaft 214 from detaching from the control rod 213 when the control head 215 drives the control shaft 214 to slide outward. A limit block 220 is fixed inside the main frame 1 on the side of the push rod 210 away from the control shaft 214. The limit block 220 is slidably connected to the control rod 213. The limit block 220 is used to limit the push rod 210 to prevent it from rotating too far when the push rod 210 pushes the second support arm 203 downward. On the other hand, the limit block 220 supports the control rod 213. The control lever 213 has a pair of slots 217, and the control shaft 214 has a pair of slots 218 fixed on it. The slots 218 slide in the slots 217. By sliding the slots 217, the control shaft 214 can always drive the control lever 213 to rotate after it is pulled out.

[0042] Working principle: When this switchgear needs to be moved, firstly, a pair of control heads 215 are pulled out of the limiting slot 216. The control heads 215 drive the control shaft 214 to slide outward. Then, the control heads 215 are rotated, causing the control shaft 214 and control rod 213 to rotate. The rotation of the control rod 213 causes the moving part 212 to move towards the limiting block 220. The movement of the moving part 212 drives the push rod 210 to rotate. At the same time, the moving part 212 slides in the slide rail 211. When the push rod 210 rotates, it pushes the second... The support arm 203 rotates downward around the fixed shaft seat 201. At the same time, the second support arm 203 drives the first support arm 202 to rotate downward. The first support arm 202 and the second support arm 203 drive the moving wheel 206 to rotate outward, so that the moving wheel 206 contacts the ground and lifts the switch cabinet upward, so that the support leg 207 is no longer in contact with the ground. Then, the control head 215 is pushed into the limit groove 216 to prevent the control rod 213 from rotating, thereby preventing the first support arm 202 and the second support arm 203 from rotating. Then the switch cabinet can be moved.

[0043] After moving to the appropriate position, the control head 215 is pulled out of the limit groove 216, and the control head 215 is rotated in the opposite direction. This causes the push rod 210 to rotate in the opposite direction. Due to the weight of the switch cabinet itself, it moves downward, thereby retracting the moving wheel 206 and allowing the support leg 207 to contact the ground for support.

[0044] When the cabinet door 102 needs to be closed on the main frame 1, first push the plate 109 to retract the locking block 107 into the main frame 1, then turn the handle 104 to lock the handle 104 into the handle groove 105, then release the push plate 109, and the spring force of the spring 108 pushes the locking block 107 into the groove 110, thereby locking the handle 104 into the handle groove 105, thus locking the cabinet door 102 onto the main frame 1. When the cabinet door 102 needs to be opened, first push the plate 109 to remove the locking block 107 from the groove 110, then use the latch 106 to latch the handle 104 out of the handle groove 105 and rotate it out, then pull the handle 104 to open the cabinet door 102.
