Description

Technical Field

[0001] The present invention relates to the technical field of functional fire power supply box structures, and in particular to a top-mounted structure of a fire power supply box with a directional auxiliary defense function sprinkler assembly. Background Art

[0002] Nowadays, power boxes are generally installed in various power distribution hubs in buildings, playing the role of power distribution, circuit control, safety isolation, maintenance and monitoring. Among them, the installation location and functionality of fire power boxes with special emergency functions are even more important;

[0003] In the existing technology, the installation of fire protection power supply is still integrated into the conventional power distribution hub. When a dangerous situation (such as fire) occurs, the elevator / corridor entrance on the floor may be blocked by the fire, making it impossible for firefighters to enter the floor smoothly to operate the various equipment in the power distribution hub on that floor;

[0004] Moreover, due to the lack of access, there is a possibility that the equipment carried by firefighters that requires power cannot be powered, and it is impossible to open a channel to complete the water supply connection to the internal fire hydrant;

[0005] Furthermore, the emergency fire power supply in the conventional power distribution hub installation area is itself threatened by fire to a great extent and can be easily damaged and rendered ineffective.

[0006] Therefore, it is necessary to improve the existing fire power supply in terms of installation location, function expansion, and usage protection. Summary of the Invention

[0055] Working principle:

[0056] The body of the fire-fighting power supply box of the present invention is installed in a preset slot of the top beam at the elevator entrance or corridor entrance. Under normal conditions, it is an upward retracted structure. A stable state is achieved through the friction coefficient between the slide groove and the convex strips on the left and right inner walls of the top beam slot, as well as the pre-tightening force of the torsion spring bottom support block below. The upper limit safety is achieved by the locking block and steel wire rope above the body, and the lower displacement safety is achieved by the pull cover below. Under normal conditions, the body of the power supply box realizes the normal functions of its internal control circuit, and the electrical wiring is arranged through the cavity channel of the ceiling panel.

[0057] When a dangerous situation (such as a fire) occurs, the building floors cannot be normally entered due to the flame obstruction. Since the main body of the fire power box is installed in the top beam of the elevator entrance or corridor entrance, it will hardly be affected and can ensure normal operation. In addition, firefighters can open the sliding cover there and pull down the functional head assembly together with the main body. Under the action of external force, the main body overcomes the obstruction of the torsion spring bottom support block and pushes it open, then moves downward and stops at the limit position under the action of the upper end wire rope;

[0058] At this time, the operator can rotate the functional head so that the nozzle mechanism at one end of the functional head is aimed at the fire. Under the action of the water pump, the multi-channel nozzle is used to spray water mist to extinguish the fire. At this time, the operator can extinguish the fire at the entrance to the floor, forming a safe passage for rescue;

[0059] Extended function 1: The power supply board at the bottom of the function head can power other auxiliary equipment carried by firefighters, further facilitating rescue;

[0060] Extended function 2: Since the main body of the fire power box is installed at the elevator entrance or corridor entrance, and there is usually a floor window opposite to the entrance floor, the escape rope reel and auxiliary hole hook at the other end of the functional head of the present invention can also play the role of life-saving rapid descent and auxiliary splicing.

[0061] The escape rope reel is a preset structure and can be used directly. It can greatly increase the rescue speed at critical moments. When idle, it can be flipped upwards counterclockwise to save horizontal space for pulling down. At the same time, the auxiliary hole hook can increase the lap anchor point of the rescue equipment.
