step four: after a plurality of electrical accessories are installed inside the cabinet body 1 through the supporting frame 6, when the upper and lower electrical accessories need to be connected, a plurality of connector lugs above the bottom electrical accessory penetrate through the movable plate 25 through electric wires to be electrically connected with the conductive plate 26 above the movable plate; the movable plate 25 is inserted into the movable groove 24 at the bottom of the transverse plate 21, the conductive plates 26 at the upper part of the movable plate 25 are tightly abutted with the conductive plates 26 at the top end in the movable groove 24, the two conductive plates 26 are smooth in power, and upper and lower electrical fittings are connected;

step five: when the smoke detector 10 at the bottom of the top cover 3 is used, an alarm signal is sent out after smoke is detected, workers and a background control system are informed, the background control system opens an electromagnetic valve inside the discharge pipe 11, fire extinguishing materials inside the fire extinguisher box 2 enter the conveying pipe 9 from the discharge pipe 11, then the fire extinguishing materials are sprayed to the inside of the cabinet body 1 through the conveying pipe 9, and the fire extinguishing materials treat internal fires; when working personnel deal with fire, the electric telescopic column 14 can be started to extend upwards to jack the top cover 3 to be separated from the cabinet body 1, the upper part of the cabinet body 1 is communicated with the outside, and the working personnel can spray fire extinguishing materials into the cabinet body 1 from the upper part; taking out the required support frame 6 according to the damage condition of internal electric fittings after fire extinguishing; when the support frame 6 is pulled out, the upper moving plate 25 is pulled out from the inside of the upper lateral plate 21.

When the cabinet is used, the whole cabinet body 1 is fixed at a position needing to be used, and a plurality of wiring terminals 17 on the side surface of the slide rail groove 8 are connected with an external circuit. An external line passes through a hole groove on one side of the cabinet body 1, so that the connection part of the line and the touch head 16 is not exposed outside, and the safe and normal use can be realized.

The support frame 6 is pulled out from the cabinet 1, and the electric accessories to be used are mounted on the upper portion of the support frame 6. A plurality of connector lug that electrical accessories outside used passes through the electric wire and is connected with the inside a plurality of line board connecting rod body of inside groove 20 to pass through the electric wire with electrical fittings and lead electrical pillar 22 electric connection, and then make electrical fittings can with the current conducting plate 26 electric connection of diaphragm 21 bottom, make things convenient for a plurality of electrical fittings of inside to connect the circular telegram each other, can make a plurality of electrical fittings in the cabinet body can normally connect work according to the needs of reality.

The braced frame 6 that will install electrical accessories installs in the inside of the cabinet body 1, and during the installation, the equal joint in the inside of slide rail groove 8 in braced frame 6's both sides inwards promotes braced frame 6, and the slide 19 of braced frame 6 both sides slides in the inside of slide rail groove 8, and the gliding direction of restriction is more stable in the removal. And the guide rails 15 on the upper and lower sides of the sliding plate 19 move in the guide grooves 18, so that the moving direction can be limited, and meanwhile, the support frame 6 is not easy to shake towards the side surface when the guide rails 15 move, the movement is more stable, and the falling is not easy to occur. When the supporting frame 6 is installed, the connecting column 28 is inserted into the positioning hole 29, the spring 27 is kept in a pressed state, the side plate 23 is not in contact with the inner side surface of the slide rail groove 8, and the normal movement of the supporting frame 6 is not influenced.

After the supporting frame 6 is installed, the conductive posts 22 correspond to the touch heads 16 in the sliding rail groove 8 one by one. The side plate 23 is pulled outwards, the connecting column 28 is pulled out from the positioning hole 29, and the spring 27 pushes the side plate 23 to move outwards, so that the side plate 23 can be abutted with the contact head 16 inside the slide rail groove 8. The side plate 23 can be normally electrified after being contacted with the touch head 16, so that the internal circuit can be normally connected with the external circuit, and the internal electric fittings can be normally used.

After a plurality of electrical accessories are installed in the cabinet body 1 through the supporting frame 6, when the upper and lower electrical accessories need to be connected, a plurality of connector lugs above the bottom electrical accessories penetrate through the movable plate 25 through electric wires to be electrically connected with the conductive plate 26 above the movable plate. And the movable plate 25 is inserted into the movable groove 24 at the bottom of the transverse plate 21, so that the conductive plates 26 at the upper part of the movable plate 25 can be tightly abutted to the conductive plates 26 at the top end in the movable groove 24, the smoothness of electric power can be kept between the two conductive plates 26, and upper and lower electrical accessories can be normally connected for use. And do not influence each other between the upper and lower electrical accessories, if one of them breaks down after, can directly outwards stimulate the electrical accessories who damages, can not cause the influence to the position of other electrical accessories, follow-up maintenance is changed simply swiftly.

If in the use after the cabinet body 1 inside conflagration trouble of taking place, send alarm signal after the smog detector 10 of top cap 3 bottom detects smog, inform staff and backstage control system, backstage control system opens 11 inside solenoid valves of discharging pipe, the inside fire extinguishing material of fire extinguisher case 2 inside enters into the inside of conveyer pipe 9 from discharging pipe 11, and then spray to the inside of the cabinet body 1 through conveyer pipe 9, fire extinguishing material can carry out timely processing to the conflagration of inside, can avoid the conflagration to stretch, reduce the loss. When the staff handled the conflagration, 14 upwards extensions on the electronic flexible post of startable break away from the cabinet body 1 with top cap 3 jack-up, the upper portion of the cabinet body 1 link up with the external world, and the staff can follow upper portion and spout into fire extinguishing materials to the inside of the cabinet body 1, and further putting out a fire improves the efficiency of putting out a fire. The cabinet body 1 has a self-protection function inside, and has better safety performance in use.

After fire extinguishment, the required support frame 6 can be taken out independently according to the damage condition of the internal electric fittings. When taking out, the side plate 23 is pressed to move inwards, the connecting column 28 enters the positioning hole 29, and the pulling-out is more stable. The supporting frame 6 can be directly pulled outwards, and the disassembling efficiency is improved. When the supporting frames 6 are pulled out, the moving plate 25 on the upper portion is pulled out from the inner portion of the upper transverse plate 21, so that the electrical accessories on the upper portion of each supporting frame 6 can be detached, replaced and installed independently, and convenience and working efficiency in use are improved.
