[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A fireproof insulated cable junction box comprises a junction box 1, a partition 2 is fixed inside the junction box 1, and the surfaces of the junction box 1 and the partition 2 are provided with fireproof insulating materials to improve the protection performance of the device body, a fire extinguishing tank 3 is installed on the partition 2, and a smoke sensor 4 is also provided inside the junction box 1. A plurality of nozzles 5 facing the electrical components are provided inside the junction box 1, and the nozzles 5 are connected with the inside of the fire extinguishing tank 3. A moving component for driving the nozzle 5 to move up and down is provided inside the junction box 1, and a swinging component for driving the nozzle 5 to swing left and right is also provided inside the junction box 1. Both the moving component and the swinging component are used to expand the spraying range of the nozzle 5.

[0025] Reference Figure 1 and Figure 3 The moving assembly includes a reciprocating screw rod 7 rotatably connected to the inner bottom surface of the junction box 1, a motor 9 is fixed on the partition 2, the output shaft end of the motor 9 is axially connected to one end of the reciprocating screw rod 7, a slide plate 6 is threadedly sleeved on the reciprocating screw rod 7, a sliding rod 8 for guiding is fixedly connected to the inner bottom surface of the junction box 1, one end of the sliding rod 8 passes through the slide plate 6, and the sliding rod 8 is slidably connected to the slide plate 6, a slide groove 10 is provided on the side wall of the slide plate 6 facing the electrical component, and the nozzle 5 is located inside the slide groove 10. By setting the moving assembly, the nozzle 5 can move under the action of the reciprocating screw rod 7, so that the fire extinguishing range can be increased in the vertical direction of the junction box 1 and the fire extinguishing efficiency is improved.

[0026] Reference Figure 2 and Figure 3 The swing assembly includes a driving plate 11 slidably connected to the inside of the slide groove 10, and a plurality of fixed blocks 13 are provided on the two inner sides directly opposite to the junction box 1. Two connecting blocks 14 matching with the fixed blocks 13 are fixedly connected to the driving plate 11. The nozzle 5 is rotatably connected to the bottom surface of the slide groove 10. Control blocks 12 are provided on both sides of the nozzle 5. All the control blocks 12 are fixedly connected to the driving plate 11. By setting the swing assembly, the nozzle 5 can swing, thereby increasing the jet area in the horizontal direction, ensuring the comprehensiveness and effectiveness of fire extinguishing.

[0027] Reference Figure 4 The inner bottom surface and the inner top surface of the slide groove 10 are both provided with guide grooves 15, the top and bottom of the driving plate 11 are respectively located inside the two guide grooves 15, and the driving plate 11 is slidably connected with the guide grooves 15. The guide grooves 15 play a limiting and guiding role in the movement of the driving plate 11, thereby ensuring the stability of the overall structure of the device.

[0028] Reference Figure 1 A buzzer 16 for reminding the public is fixedly connected to the side wall of the junction box 1. When the smoke sensor 4 detects a fire, the buzzer 16 will make a sound to promptly remind the surrounding people to evacuate, thereby reducing the threat of fire to the public. It is worth mentioning that the smoke sensor 4, the motor 9, the valve of the fire extinguisher 3 and the buzzer 16 are all connected to the PLC controller. The specific connection method and working principle are not the innovation points of the utility model, and will not be elaborated here.

[0029] Reference Figure 1 and Figure 2 The fixing blocks 13 on the same side are arranged at equal intervals, and the longitudinal section of the fixing block 13 is an isosceles triangle structure. When the connecting block 14 contacts the fixing block 13, the connecting block 14 can move under the action of the inclined surface of the fixing block 13.

[0030] The specific working principle of the utility model is as follows:

[0031] When a fire occurs inside the junction box 1, the smoke sensor 4 detects that the smoke data is abnormal. At this time, the valve of the fire extinguisher tank 3 is opened, and the fire extinguishing gas in the fire extinguisher tank 3 is sprayed toward the electrical equipment through the nozzle 5. There is no need to wait for the staff to rush to the scene to manually extinguish the fire, which ensures the timeliness of fire extinguishing. Such timely measures can reduce the spread of fire, on the one hand, reduce the threat to the safety of the surrounding people, and on the other hand, reduce property losses. At the same time as the valve of the fire extinguisher tank 3 is opened, the motor 9 is started, and the output shaft of the motor 9 rotates to drive the reciprocating screw rod 7 to rotate. Under the guidance of the slide rod 8, the slide plate 6 will not rotate with the reciprocating screw rod 7, but will move along the axis direction of the reciprocating screw rod 7, which will drive the nozzle 5 to move together, so that the fire extinguishing gas can be evenly sprayed on the electrical equipment in the vertical direction, preventing the fire extinguishing gas from missing the fire source and affecting the fire extinguishing effect;

[0032] Furthermore, during the movement of the slide plate 6, the connecting block 14 moves along with it. When one of the connecting blocks 14 contacts one of the fixed blocks 13 on the same side thereof, the fixed block 13 will squeeze the connecting block 14 under the action of the inclined surface on the fixed block 13, so that the connecting block 14, the drive plate 11 and the control block 12 move together in a direction away from the fixed block 13, so that the control block 12 will squeeze one end of the nozzle 5, so that the nozzle 5 will swing. Conversely, when the other connecting block 14 contacts the fixed block 13 on the corresponding side, it will also drive the nozzle 5 to swing toward the other side. Under the action of the fixed blocks 13 on both sides, the nozzle 5 will swing back and forth under the action of the control block 12, so that the fire extinguishing gas can fully extinguish the electrical equipment in the direction perpendicular to the axis of the reciprocating screw 7, further ensuring the comprehensiveness and effectiveness of the fire extinguishing.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
