The partition plate 2 divides the inside of the cabinet body 1 into a lower large part and an upper small part, forming a low-voltage chamber 3 and a high-voltage chamber 4. At the opening of the cabinet body 1, a door panel 5 is provided. Between the cabinet body 1 and the door panel 5, a rectangular expansion frame 6 is provided. The door panel 5 is rotatably arranged on the side of the expansion frame 6 away from the cabinet body 1. Inside the expansion frame 6, accommodation cavities (not shown in the attached drawing) for placing the conveying pipes 7 are respectively opened on the left and right sides along the height direction of the cabinet body 1. And accommodation grooves 43 communicating with the accommodation cavities are opened at the upper and lower ends inside the expansion frame 6. One end of the conveying pipe 7 located inside the accommodation cavity is provided with a branch pipe (not shown in the attached drawing) passing through the inside of the accommodation cavity. On the outer wall of the cabinet body 1, a conveying pump 8 is provided. The conveying pipe 7 is connected to the output end of the conveying pump 8 through the branch pipe. The upper and lower ends of the conveying pipe 7 are respectively located in the accommodation grooves 43 at the upper and lower ends inside the expansion frame 6, and are respectively sleeved with bottom plates 25, as Figure 7 shown.

Specifically, the fire extinguishing agent can be water or fire extinguishing powder, and the output nozzle 9 can be a nozzle for spraying water or powder.

[0034] Placing cavities 44 are oppositely opened along the length direction inside the expansion frame 6. Inside the two placing cavities 44, rotating cylinders 13 are respectively vertically arranged. An inflatable pad 14 is wound around the outer wall of the rotating cylinder 13. One end of the inflatable pad 14 passes through the placing cavity 44 and is located inside the expansion shell. The other end of the inflatable pad 14 communicates with the inside of the rotating cylinder 13. The lower end of the rotating cylinder 13 is connected to an air pump (not shown in the attached drawing) through the conveying pipe 7. On the left and right ends inside the expansion frame 6, brackets 16 are horizontally slidably arranged. One end of each of the two inflatable pads 14 located inside the expansion frame 6 is respectively connected to the outer walls of the two brackets 16. On the side of the two brackets 16 away from each other, sliding grooves 17 are opened along their length directions. On the inner wall of the expansion frame 6, a rotating rod 18 is rotatably arranged. One end of the rotating rod 18 is slidably connected to the sliding groove 17 through a movable rod 19. On the outer wall of the cabinet body 1, a push rod 20 is horizontally slidably arranged. One end of the push rod 20 penetrates into the cabinet body 1 and is opposite to the lower end of the rotating rod 18. On the other end of the push rod 20, a wedge-shaped block 1 is provided. A wedge-shaped block 2 is slidably engaged with the wedge-shaped block 1. On the outer wall of the cabinet body 1, a pushing member 23 is provided. The top end of the pushing member 23 is connected to one end of the wedge-shaped block 2 away from the wedge-shaped block 1. In this embodiment, the pushing member 23 is a cylinder.

[0035] On each side where the two sets of brackets 16 are away from each other, an expansion member is provided. The expansion member includes two sets of connecting plates 24 arranged crosswise. The upper and lower ends of the connecting plates 24 are respectively slidably connected to the inner wall of the expansion frame 6 and the brackets 16. In this embodiment, four sets of expansion members are provided, and two sets of expansion members are provided on one set of brackets 16 and are arranged vertically opposite to each other. The purpose is to be able to further support the position of the brackets 16 inside the expansion frame 6.

[0036] On the upper side of the inner wall of the low-voltage chamber 3, a housing 35 is horizontally arranged along the length direction of the cabinet body 1. A rotating rod 11 is horizontally rotatably arranged inside the housing 35. A heat insulation pad 12 is wound around the outer wall of the rotating rod 11. An outlet (not shown in the drawings) for the heat insulation pad 12 to extend out is provided on the lower side of the housing 35. As Figure 8 shown, a driven wheel 38 is sleeved on one end of the rotating rod 11. A support rod 36 is also rotatably arranged inside the housing 35. The support rod 36 is arranged vertically. A driving wheel 37 meshing with the driven wheel 38 is sleeved on its lower end. A driving rope 39 is wound around the upper end of the support rod 36. The top end of the driving rope 39 is connected to the outer wall of the bracket 16 on the side away from the door panel 5 through a fixing block 40. The purpose is that when the two sets of brackets 16 slide horizontally and approach each other inside the expansion frame 6, by pulling the driving rope 39, the driving rope 39 will pull the support rod 36 to rotate. The support rod 36 drives the driving wheel 37 to mesh and drive with the driven wheel 38, thereby driving the rotating rod 11 to rotate and making the heat insulation pad 12 move downward to block the front ends of the low-voltage chamber 3 and the high-voltage chamber 4 of the cabinet body 1.

[0037] Two sets of pressing plates 28 are respectively arranged at the low-voltage chamber 3 and the high-voltage chamber 4 inside the cabinet body 1. The pressing plates 28 are horizontally placed and are respectively located at the upper and lower ends of the low-voltage chamber 3 and the high-voltage chamber 4. And through holes 30 are opened on both sides of the end of the inner wall of the cabinet body 1 away from the door panel 5. Connecting ropes 29 are connected to the left and right ends of each set of pressing plates 28. A roller one 32 is horizontally rotatably arranged inside the through holes 30. One end of the connecting rope 29 located inside the through holes 30 is in sliding contact with the surface of the roller one 32. One ends of the connecting ropes 29 on the same side of the cabinet body 1 are connected to a handle 31 outside the cabinet body 1. The purpose is that personnel can pull the connecting ropes 29 on the same side simultaneously through the handle 31.

[0038] Elastic members are arranged below each set of through holes 30 on the inner wall of the cabinet body 1. The elastic members include a base 41 connected to the inner wall of the cabinet body 1 and an elastic piece 42 arranged on the base 41. The purpose is that when the pressing plate 28 is pulled and passes through the elastic piece 42, the elastic piece 42 will reset. When the pressing plate 28 moves back due to inertia or external impact, it will be blocked by the elastic piece 42 to prevent the pressing plate 28 from moving back when pressing the heat insulation pad 12.

[0039] In this embodiment, the driving rope 39, the connecting rope 29, and the elastic member are all composed of high-temperature-resistant metal materials.

[0040] On the side of the partition plate 2 facing the opening of the cabinet body 1, a second roller 33 is provided, and on the side of the pressing plate 28 away from the opening of the cabinet body 1, a third roller 34 is provided. The purpose is that when the pressing plate 28 is driven to press the heat insulation pad 12 to cover the electrical components in the low-voltage chamber 3 and the high-voltage chamber 4, the frictional force between the partition plate 2 and the pressing plate 28 and the contact surface of the heat insulation pad 12 can be smaller, which is more conducive to the stretching of the heat insulation pad 12.

[0041] When the electrical components in the low-voltage chamber 3 and the high-voltage chamber 4 in the cabinet body 1 are working normally, the two groups of brackets 16 are located at the left and right ends inside the expansion frame 6, the pressing plate 28 is at one end facing the expansion frame 6, the pushing member 23 is in a retracted state, the entire output nozzle 9 is located in the receiving groove 43, the torsion spring 26 is in a stressed and twisted state, and the delivery pump 8 is in a stopped state.

[0042] When an electrical component in the cabinet body 1 overheats or catches fire due to a short circuit, the personnel first activate the pushing member 23. The second wedge block 22 on the pushing member 23 moves downward, pushing the first wedge block 21 to slide horizontally. The push rod 20 under the first wedge block 21 moves horizontally toward the inside of the cabinet body 1, pushing the lower end of the rotating rod 18. The rotating rod 18 starts to rotate around the central axis of the connection between its lower end and the inner wall of the expansion frame 6. Its upper end pushes the bracket 16 to move horizontally toward the middle inside the expansion frame 6, and the inflatable pad 14 is pulled synchronously. When the two groups of brackets 16 are in contact, the air pump starts to inflate the inflatable pad 14 to block the opening of the expansion frame 6. The purpose is to reduce the splashes generated by the fire from splashing out of the cabinet body 1. At this time, the bottom plate 25 in the receiving groove 43 is driven by the torsion spring 26 to rotate a certain angle around the central axis of the output pipe, so that the top of the output nozzle 9 moves out of the receiving groove 43 and points into the cabinet body 1. At the same time, when the bracket 16 moves, it will pull the driving rope 39. Through the meshing transmission of the driving wheel 37 and the driven wheel 38, the heat insulation pad 12 is indirectly driven to extend out of the housing 35 and block in front of the electrical components in the low-voltage chamber 3 and the high-voltage chamber 4. After the heat insulation pad 12 is fully stretched, the personnel pull the two groups of handles 31 outside the cabinet body 1, and the pulling direction is to pull away from each other on the left and right sides of the cabinet body 1, driving the connecting rope 29. The four pressing plates 28 start to push the heat insulation pad 12 closer to the electrical components in the cabinet body 1. The heat insulation pad 12 is divided into upper and lower covering surfaces by the four pressing plates 28, respectively covering the electrical components in the low-voltage chamber 3 and the high-voltage chamber 4. The personnel pull the connecting rope 29 until the pressing plate 28 moves past the elastic piece 42. At this time, the return of the pressing plate 28 will be blocked by the upper end of the elastic piece 42, and the delivery pump 8 starts to operate, transporting the fire extinguishing agent in the storage box 10 to the output nozzle 9, and the output nozzle 9 starts to output the fire extinguishing agent.

[0043] The above embodiments are illustrative of the present invention and not restrictive thereof. Any solution obtained by simply transforming the present invention falls within the protection scope of the present invention.
