Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a shockproof high and low voltage switch cabinet. Background Art

[0002] High and low voltage switchgear is an electrical device mainly used to receive high or low voltage cables. The external lines of this equipment will first enter the main control switch in the cabinet, and then enter the sub-control switch. Each branch is set according to its needs. For example, instruments, automatic control, motor magnetic switches, and various AC contactors may be set up. Some switchgears will also have high-voltage and low-voltage rooms with high-voltage busbars, such as in power plants and other places. In addition, some switchgears will be equipped with low-frequency load reduction and other functions. High and low voltage switchgear can be divided into many types, including low-voltage withdrawable switchgear. When operating high and low voltage switchgear, there are some important safety technical operating procedures that need to be paid attention to, such as switchgear, AC low-voltage distribution cabinet, metal armored removable switchgear, low-voltage fixed partition switchgear, high-voltage capacitor cabinet and high-voltage switchgear. For example, when working on a fully or partially energized panel, the maintenance equipment should be separated from the operating equipment with obvious signs. In addition, the secondary windings of the current transformer and voltage transformer should have permanent and reliable protective grounding. When working on the secondary circuit of a running current transformer, some specific safety measures should be taken.

[0003] Although the existing high and low voltage switch cabinets can protect the high and low voltage equipment inside them, when the cabinet is impacted by external force, the overall structure cannot play a good buffering and shock-absorbing effect, which causes the high and low voltage equipment inside to be easily displaced, and then the cables are broken. It is necessary to replace new cables and reconnect them, which is troublesome. In addition, when one of the cables is broken, electric sparks are likely to occur, which in turn affects other cables. The safety is poor. Therefore, a shockproof high and low voltage switch cabinet is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a shockproof high and low voltage switch cabinet, which solves the problem that the internal high and low voltage equipment is easily displaced due to the overall structure not being able to play a good buffering and shock absorbing effect, and then the cables are broken. It is necessary to replace new cables and re-wire them, which is rather troublesome. In addition, when one of the cables is broken, electric sparks are likely to occur, which in turn affects other cables, resulting in poor safety.

[0005] To achieve the above object, the utility model provides the following technical solutions: a shockproof high and low voltage switch cabinet, comprising a switch cabinet body, high and low voltage equipment, a base and a substrate, wherein shockproof mechanisms are arranged inside the switch cabinet body and the base;

[0006] The anti-vibration mechanism includes a threaded rod fixedly connected to the inside of the switch cabinet body, the outer surface of the threaded rod is slidably connected to a pressure plate, the outer surface of the threaded rod is threadedly sleeved with a locking nut, the bottom of the pressure plate is fixedly connected to a No. 1 damper, the back of the base is provided with a threaded hole, the internal thread of the threaded hole is connected to a threaded column, the front end of the threaded column is fixedly connected to a No. 2 damper, the tops of the No. 1 damper and the No. 2 damper are both bonded with rubber insulating pads, and the rear end of the threaded column is fixedly connected to a turntable.

[0007] Furthermore, the top and bottom of the turntable are fixedly connected to a limit frame, the inner side of the limit frame is sleeved with a nylon belt, and the top end of the nylon belt is fixedly connected to a limit ring.

[0008] Furthermore, a hook is fixedly connected to the back side of the base, and the limiting ring is hung on the hook.

[0009] Furthermore, an armrest lock buckle is fixedly installed on the top of the base plate, and fixed blocks are fixedly connected to the left and right sides of the base.

[0010] Furthermore, the armrest locks are relatively distributed on the left and right sides of the base, and the armrest locks are clamped with the fixing block.

[0011] Furthermore, a cabinet door is installed on the front of the switch cabinet body through a hinge, and a handle and a door lock are arranged on the front of the cabinet door.

[0012] Furthermore, a ventilating hole for heat dissipation is provided on the outer surface of the cabinet door, and a filter screen for dust prevention is fixedly connected to the inner side of the ventilating hole.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The shockproof high and low voltage switch cabinet achieves the effect of buffering and shock absorption by setting a shockproof mechanism. When in use, the tightening nut can limit the position of the pressure plate, so that the No. 1 damper can firmly press the high and low voltage equipment inside the switch cabinet body to avoid displacement, thereby reducing the probability of cable breaking. It has good safety, and the staff only needs to turn the turntable clockwise to drive the No. 2 damper to move forward continuously through the threaded column, so that it can firmly press against the back of the switch cabinet body, thereby preventing the switch cabinet body from being violently vibrated due to external force impact.

[0015] 2. The shockproof high and low voltage switch cabinet, through the cooperation of the limit frame, nylon belt, limit ring and hook, when the No. 2 damper is against the back of the switch cabinet body, the staff only needs to pick up the limit ring and hang it on the inside of the hook to limit the turntable to prevent it from continuing to rotate due to external force. The handrail lock and fixed block can also limit the base to the top of the substrate, improve its stability and reduce the probability of tipping. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the locking nut 6 can limit the position of the pressure plate 5, so that the damper No. 1 7 can firmly press the high and low voltage equipment 2 inside the switch cabinet body 1 to avoid displacement, thereby reducing the probability of cable breaking.

[0025] The staff only needs to rotate the turntable 12 clockwise to drive the second damper 10 to move forward continuously through the threaded column 9, so that it can firmly press against the back of the switch cabinet body 1, thereby preventing the switch cabinet body 1 from vibrating violently due to external impact.

[0026] Among them, the top and bottom of the turntable 12 are fixedly connected to the limit frame 13, the inner side of the limit frame 13 is sleeved with a nylon belt 14, the top of the nylon belt 14 is fixedly connected to the limit ring 15, the back of the base 3 is fixedly connected with a hook 16, and the limit ring 15 is hung with the hook 16. Through the cooperation of the limit frame 13, the nylon belt 14, the limit ring 15 and the hook 16, when the No. 2 damper 10 is against the back of the switch cabinet body 1, the staff only needs to pick up the limit ring 15 and hang it on the inner side of the hook 16 to limit the turntable 12 and prevent it from continuing to rotate due to external force.
