Example one

This embodiment provides a switch board extinguishing device. As shown in figure 1, the fire extinguishing device of the power distribution cabinet comprises a movable seat 1, an isolation box 2, a pull rod mechanism 3 and a fire extinguishing agent spraying mechanism 4. Isolation box 2 sets up in the top that removes seat 1, and the top of isolation box 2 and the equal uncovered setting of one end of the side of isolation box 2 along first direction. The drawbar mechanism 3 comprises a first slide 31 and a drawbar 32 which are slidably connected. The first slide 31 is arranged on the mobile seat 1. A suction cup 34 is provided at one end of the pull rod 32. When the pull rod 32 slides to the first position along the first slide seat 31, the suction cup 34 can be attracted with the power distribution cabinet; when the pull rod 32 is slid along the first slide 31 into the second position, the switch cabinet can be tilted and poured into the insulation box 2 by means of the suction cup 34. The fire extinguishing agent injection mechanism 4 is arranged on the movable seat 1, a first outlet is arranged at the outlet end of the fire extinguishing agent injection mechanism 4, and the first outlet is communicated with the cavity of the isolation box 2.

When a certain switch board in the switch board room is on fire, remove seat 1 through the removal and can push away this switch board extinguishing device before the switch board on fire to make the uncovered switch board that aims at on fire of shielded cell 2. Then, the pull rod 32 is pushed to enable the suction cup 34 to be attracted with the power distribution cabinet on fire, and the pull rod 32 is pulled to enable the power distribution cabinet on fire to incline towards the isolation box 2 through the suction cup 34. When the switch board that fires inclines to certain angle, it just can be by the uncovered pouring of shielded box 2 in the cavity of shielded box 2 to make the switch board that fires keep apart with switch board on every side under shielded box 2's effect. Finally, spout into fire extinguishing agent through fire extinguishing agent injection mechanism 4 in to the cavity of shielded box 2, just can put out a fire to the switch board on fire, thoroughly avoid stretching of condition of a fire, reduce the loss of fire to the at utmost.

In the present embodiment, the specific arrangement of the isolation box 2 is a rectangular box structure as shown in fig. 1 and 2, and is fixedly arranged on the right side of the bottom plate 11.
