Water pipe connection ports 12 are arranged at both the upper end and the lower end of the water passing channel 11. A water pump 13 connected to an external water supply pipe is arranged at the upper end of the top beam 1. Water pipes are connected between the output end of the water pump 13 and the water pipe connection port 12 at the upper end of the water passing channel 11, and between the water pipe connection port 12 at the lower end of the water passing channel 11 and the water inlet 14 of the nozzle mechanism; The escape rope reel assembly includes an escape rope reel 15 rotatably arranged on the function head 5. A limit support block 16 is provided at the lower end of the escape rope reel 15, and an auxiliary hole hook 17 is also provided on the limit support block 16.

[0026] Among them, the lower end of the top beam 1 abuts against the lower end of the body 2 through a torsion spring base block 18. A locking block 19 and a steel wire rope 20 are provided at the upper end of the top beam 1. The steel wire rope 20 is connected to the bolt hole 21 at the upper end of the body 2 through a bolt at the end.

[0027] The docking shaft 10 is installed on the mounting plate 22 in the concave cavity 9.

[0028] The external wiring terminal assembly includes a power supply socket 23 and an indicator light 24.

[0029] The nozzle mechanism includes a water inlet tank 25. Multi-channel nozzles are provided at the outer end of the water inlet tank 25. The inner end of the water inlet tank 25 is connected to the docking shaft 10 through a tight pressing shaft kit 26. The water inlet 14 is provided at the upper end of the water inlet tank 25.

[0030] The multi-channel nozzle includes a central direct injection channel 27 and an outer inclined injection channel 28.

[0031] Extension guide plates 29 are provided at the outer ends of both the direct injection channel 27 and the inclined injection channel 28.

[0032] The function head assembly is arranged in the ceiling board cavity channel 30 at the lower end of the top beam 1, and a pull cover 31 is provided at the lower end of the ceiling board cavity channel 30 where the function head assembly is located.

[0033] Working principle: The body of the fire power supply box of the present invention is installed in a preset slot on the top beam at the elevator entrance or the corridor entrance. In the normal state, it is a retracted structure. The stable state is achieved through the friction coefficient between the chute and the ridges on the left and right inner walls of the top beam slot and the pre-tightening force of the lower torsion spring base block. The upper limit insurance is achieved through the locking block and the steel wire rope above the body, and the lower displacement insurance is achieved through the lower pull cover. In the normal state, the body of the power supply box realizes the normal functions of its internal control circuit, and the electrical wiring is arranged in the ceiling board cavity channel; When a dangerous situation (such as a fire) occurs, it is impossible to enter normally due to the obstruction of the flame in the building floor. Since the installation position of the body of the fire power supply box is in the top beam at the elevator entrance or the corridor entrance, it is hardly affected itself and can ensure normal operation. In addition, the fireman can open the pull cover here, pull down the function head assembly together with the body. The body overcomes the obstruction of the torsion spring base block under the external force and pushes it away, then displaces downward, and stops under the limitation of the upper steel wire rope; At this time, the operator can rotate the functional head so that the nozzle mechanism at one end of the functional head is aligned with the fire location. Under the action of the water pump, water mist is sprayed through the multi-channel nozzle for fire extinguishing. At this time, it is realized that the operator can extinguish the fire at the entrance of the passage into the floor, forming a safe passage for entering the rescue. Expansion function 1: The power supply socket at the lower end of the functional head can supply power to other auxiliary equipment carried by the firefighters, further facilitating the rescue. Expansion function 2: Since the installation position of the body of the fire protection power supply box is at the elevator entrance or the corridor entrance, and generally there is a floor window opposite this place relative to the entrance to the floor. At this time, the escape rope reel and the auxiliary hole hook at the other end of the functional head of the present invention can also play the functions of life-saving rapid descent and auxiliary latching.

[0034] The escape rope reel is a preset structure and can be directly used. It can greatly improve the rescue speed at critical times. When idle, it can be turned up counterclockwise to save the horizontal space for pulling down. At the same time, the auxiliary hole hook can increase the latching anchor points of the rescue equipment.
