Abstract

The utility model relates to a quick-automatic-opening fire hydrant box. In the utility model, on the basis of the present roll type fire hydrant box, an automatic unlocking device and a hose roll automatically releasing device are arranged. The utility model can be connected with an automatic fire alarm system. After a signal from a fire monitoring center is obtained, a box door can automatically and quickly open for standby application for releasing a hose roll. The utility model which can save precious time for fire protection can be widely used for the indoor fire protection system of a workshop, the indoor fire protection system of a warehouse, the indoor fire protection system of a high building, and the indoor fire protection systems of other public buildings.

Description

The fire hydrant box of fast automatic unlatching

The utility model is that a kind of being installed in has the case shape permanent fire protection system that the feedwater fire extinguishing waits effect in the building, belongs to fire-fighting domain.

Existing fire hydrant box is mainly by the fire hydrant in casing and the case thereof, the water band, hose roll, fire-fighting equipment such as hydraulic giant and electric equipment is formed, wherein fire hydrant is fixed in the casing, water band one end is connected with fire hydrant, the water band other end is connected with hydraulic giant, the water band is crimped onto on the hose roll, hose roll is installed in and turns the turning on the plate axle of plate arm, the other end that turns the plate arm is installed on the wall box by a rotating shaft, during use, open chamber door by the fire fighter, again hose roll is pulled out in case, extract the water band again out and put out a fire, but fire-fighting fire extinguishing is an important process of seizing every minute and second, and above-mentioned fire hydrant box still seems complicated operation and influences blow-off velocity.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, design a kind of simple in structure, easy to use, can fast automatic unlatching chamber door and discharge the fire hydrant box of hose roll.

Technical measures of the present utility model are to increase auto-unlocking device and the automatic releasing device of hose roll on the basis of existing fire hydrant box, wherein, the auto-unlocking device is made up of door lock electromagnet and armature, armature is contained in the back side of the press button of chamber door springboard lock with screw, the door lock electromagnet is contained on the wall box with the armature opposite position, and the door lock magnet spool is connected with the signal power source at fire monitoring center; The automatic releasing device of hose roll is made up of tractive magnet, fixed mount, latch, stage clip and torsion spring, torsion spring is contained in and turns in plate arm and the rotating shaft that casing is connected, make the power that the plate arm has a kind of rotation outside chamber door that turns, the pin tongue retaining of latch is on the edge of hose roll, the latch afterbody is connected with pin with the iron core of tractive magnet after passing the stage clip that is contained in fixed mount, fixed mount is installed on the interior appropriate location of case, and the tractive magnet coil is connected with the signal power source at fire monitoring center.When receiving fire alarm, the fire monitoring center just connects the fire signal power supply, make the energising of door lock electromagnet and tractive magnet produce magnetic force, attract respectively door lock armature and with latch from the retaining draw back at the edge of hose roll, can open door lock respectively and the torsion of torsion spring will be turned and pull arm and drive hose roll and rush open chamber door and produce casing and be in dormant state, for fire-fighting fire extinguishing gains time.

Accompanying drawing 1 is the structural representation of the utility model fire hydrant box;

Accompanying drawing 2 be the auto-unlocking device structural representation;

Accompanying drawing 3 is structural representations of the automatic releasing device of hose roll.

Referring to accompanying drawing 1, the fire hydrant box of fast automatic unlatching of the present utility model mainly by casing 6, fire hydrant 8, hose roll 5, water band 3, hydraulic giant 1, turn plate arm 7, auto-unlocking device 4 and stop device 2 and form, wherein the auto-unlocking device is made up of door lock electromagnet and armature, referring to Fig. 2, armature 10 usefulness screws are contained in the back side of the press button 12 of chamber door springboard lock 11 among the figure, door lock electromagnet 9 be contained in armature 10 corresponding wall box on, the door lock magnet spool is connected with the signal source at fire monitoring center.The installation of armature 10 does not influence the manual function of press button 12.The automatic releasing device of hose roll is referring to Fig. 3, the plate arm 7 that turns that supports hose roll is installed on the wall box 6 by rotating shaft 13, torsion spring 14 is contained in the rotating shaft 13, torsion spring one end is connected with casing, the torsion spring other end with turn the plate arm and be connected, make the power that the plate arm has a kind of rotation outside chamber door that turns, by tractive magnet 18, fixed mount 17, latch 15 and stage clip 16 are formed stop device, the pin tongue retaining of latch 15 is on the edge of hose roll 5, hose roll can be released because of the torsion of torsion spring 14 to be produced, the afterbody of latch 15 passes stage clip 16 backs that are contained on the fixed mount 17 and is connected with the iron core of tractive magnet 18, the coil of tractive magnet is connected with the signal power source at fire monitoring center, elastic force because of stage clip 16 stretches out the pin tongue at ordinary times, producing magnetic force when the coil switch power of tractive magnet will sell tongue by iron core and retract, also available hand is pushed iron core and will be sold tongue and retract, and latch is the inclined-plane at the pin lingual surface towards chamber door, so that water band rotating disk is pushed back in the case.After the fire power supply is switched on, the door lock electromagnet is inhaled moving armature and is opened door lock, tractive magnet retracts from retaining latch at the edge of hose roll, turn the plate arm under the torsion of torsion spring, with rushing open the chamber door of the lock that is opened, hose roll produces casing, be in dormant state, directly the open the door iron core of pushing tractive magnet again of the still available hand of maintaining at ordinary times will be sold tongue and retract and can discharge hose roll.

The utility model possesses automatically and manual function simultaneously, has the structure letter The advantage such as single, stable and reliable for performance and easy to use can be reported automatically with fire The alarm system networking, behind the signal of receiving the fire monitoring center, can be automatically fast Speed is opened chamber door, and the releasing water belt reel is for fire-fighting fire extinguishing has won valuable Time, be widely used in factory building, storehouse, absciss layer building and other public building The indoor fire extinguishing system of building.
