[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, circuit breakers and distribution cabinets in the power system. The distribution cabinet is used to distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load and provide protection, monitoring and control for the load.

[0003] After searching, CN 221408062 U, an electrical protection device, is found. Dry ice is placed on a mesh plate in a first chamber. After a fire occurs in a second chamber, a motor is driven to rotate the opening and closing member to an open position to connect the first chamber and the second chamber. The vaporized dry ice extinguishes the fire.

[0004] However, the above application still has certain defects: the above application emphasizes the use of dry ice to extinguish the fire source, but the dry ice needs to be stored at a very low temperature (at least minus 78.5°C), and the storage conditions are harsh. Moreover, after the dry ice enters the second chamber from the first chamber, it still takes a period of time to evaporate before it can be used to extinguish the fire. The fire source cannot be extinguished immediately, and there are certain defects in the fire extinguishing efficiency. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

When a fire occurs in the device main body 1 due to overload or short circuit, the controller 8 controls the opening of the fire extinguisher bottle while controlling the operation of the drive assembly. In the process of the drive assembly driving the first slide 13 and the second slide 14 to move up and down, the nozzle 6 can be driven to spray the dry powder fire extinguishing agent up and down, thereby achieving full coverage of the fire extinguishing treatment inside the device main body 1 to prevent the spread of fire.

[0025] In addition, a sensor 9 is installed on the top surface of the second chamber 3. The sensor 9 is electrically connected to the controller 8. The sensor 9 can sense the smoke in the device main body 1 in the first time, so that the controller 8 can control the fire extinguishing operation in time.

[0026] Embodiment 2

[0027] This embodiment is improved on the basis of Embodiment 1. Specifically:

[0028] Please refer to Figure 2-4 , the sliding member 5 includes a first sliding plate 13, a second sliding plate 14 and a plurality of connecting rods 15 installed between the first sliding plate 13 and the second sliding plate 14. A through hole 16 is further formed on the second sliding plate 14. A reversing rod 18 is rotatably arranged in the through hole 16 through a mounting shaft 17. One end of the reversing rod 18 is fixedly installed with the spray head 6. A power component for driving the reversing rod 18 to swing reciprocally is further arranged on the first sliding plate 13 and the second sliding plate 14. The arrangements of the reversing rod 18, the mounting shaft 17 and the power component can, during the process that the spray head 6 is driven to move up and down reciprocally, the power component can drive the reversing rod 18 to reciprocally turn around the mounting shaft 17, thereby increasing the spraying range of the spray head 6 and avoiding the phenomenon of spraying dead angles, and further improving the fire extinguishing effect.

[0029] Specifically, the power component includes a movable plate 19, a slide rail 20, a driving member 21, a dial rod 22 and a power module. A pair of slide rails 20 are fixedly arranged on the side surface of the second sliding plate 14. The movable plate 19 is fixedly and slidably arranged between the two slide rails 20. A pair of driving members 21 are fixedly arranged on the side surface of the movable plate 19. The driving member 21 is in a "冂" - shaped structure. The dial rod 22 is fixedly installed at the end of the reversing rod 18. The dial rod 22 is movably arranged between the two driving members 21. The power module is used to provide power for the reciprocating movement of the movable plate 19.

[0030] Preferably, the power unit includes a gear 23 rotatably arranged on the side surface of the first sliding plate 13, a round rod 25 fixedly installed at an eccentric position of the gear 23 and a straight rack 24 meshing with the gear 23. The straight rack 24 is fixedly installed in one of the limit rails 4. A strip - shaped hole 26 for the round rod 25 to slide is further formed on the movable plate 19. With the arrangement of this power unit, during the process that the first sliding plate 13 and the second sliding plate 14 move up and down, through the meshing of the straight rack 24 and the gear 23, the round rod 25 can be driven to revolve around the axis of the gear 23. When the round rod 25 slides in the strip - shaped hole 26 of the movable plate 19, it can drive the movable plate 19 to reciprocate, without additionally arranging a driving element, reducing the cost of the power component.

[0031] Working principle: When the sensor 9 senses smoke or fire in the device body 1, the sensor 9 sends an electrical signal to the controller 8, and the controller 8 immediately controls the opening of the fire extinguisher bottle and controls the operation of the motor 12. When the motor 12 drives the screw 10 to rotate, the first slide 13, the second slide 14 and the nozzle 6 can be driven to reciprocate up and down. Moreover, during the reciprocating movement of the nozzle 6, the engagement of the spur rack 24 with the gear 23 can drive the round rod 25 to revolve around the axis of the gear 23. When the round rod 25 slides in the bar hole 26 of the movable plate 19, it can drive the movable plate 19 to reciprocate. The two driving parts 21 on the movable plate 19 contact the lever 22, which can drive the flip rod 18 to flip back and forth within a certain angle range, thereby driving the change of the spray angle of the nozzle 6 and enabling the nozzle 6 to cover every corner of the device body 1, thereby realizing a comprehensive fire extinguishing operation in the device body 1.
