Description

Technical Field

[0001] The utility model belongs to the technical field of fire hydrants, and specifically relates to an intelligent smoke alarm device for fire hydrants. Background Art

[0002] Fire hydrants, formally called fire hydrants, are fixed fire-fighting facilities whose main function is to control combustibles, isolate combustibles, and eliminate ignition sources. They can be used to extinguish fires in the early stages of a fire, and if the fire cannot be extinguished, they can also provide necessary assistance for the safe evacuation of personnel. Fire hydrants are mainly divided into indoor fire hydrants and outdoor fire hydrants;

[0003] Indoor fire hydrants are used to supply water to the fire scene through indoor pipe networks. They have valve interfaces and are usually installed in fire hydrant boxes. They are equipped with fire hoses, water guns and other equipment. They can be used in high-rise buildings, factories, warehouses, public places and other indoor environments.

[0004] At present, fire hydrants used indoors are generally not equipped with locking devices, which means that non-rescue personnel and maintenance personnel can easily open the door. This situation not only provides an opportunity for cheap people to steal water from fire hydrants, but may also affect the normal use of fire hydrants in emergency situations, thereby posing a potential threat to fire prevention and control work. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent smoke alarm device for fire hydrants, which can self-lock the door when there is no fire, and can effectively prevent others from stealing fire water, thereby ensuring the safety and reliability of fire-fighting equipment and providing solid protection for responding to sudden fire incidents.

[0007] The fire hydrant intelligent smoke alarm device comprises a box body, the inner bottom wall of the box body is provided with a fire hydrant body, the inner side of the box body is provided with a water hose reel, one side of the box body is rotatably provided with a box door, one side of the box door is provided with glass, the inner top wall of the box body is provided with a circuit box, the inner wall of the circuit box is provided with a single-chip computer, the top of the box body is provided with a smoke sensor electrically connected to the single-chip computer, the top of the box body is provided with an infrared flame detection sensor electrically connected to the single-chip computer, the inner side of the box body is fixed with a mounting block, the interior of the mounting block is provided with a mounting groove, and the inner side of the mounting block is provided with a mounting groove. The bottom wall is provided with an electromagnet electrically connected to the single-chip computer, an iron block is provided on the inner side of the installation groove and above the electromagnet, sliders are fixed on both sides of the iron block, a slide groove slidably connected to the slider is provided on the inner side of the installation groove, a spring is fixed on the inner side of the slide groove, and the top of the spring is fixed to the bottom wall of the slider, a latch is fixed on the top of the iron block, a guide hole slidably connected to the latch is provided at the top of the installation block, a fixing plate is provided on one side of the box door, a pin hole is provided on the outer wall of the fixing plate corresponding to the latch, and an alarm button electrically connected to the single-chip computer is provided on one side of the box door.

[0008] Furthermore, the outer wall of the box is provided with a power lock electrically connected to the electromagnet.

[0009] Furthermore, a speaker is disposed on one side of the box, and a microphone is disposed on the outer wall of the box below the speaker. Both the speaker and the microphone are electrically connected to the single-chip computer.

[0010] Furthermore, a warning emergency light is fixed on one side of the door and above the glass, and the warning emergency light is electrically connected to the single-chip microcomputer.

[0011] Furthermore, a networked alarm is provided on the inner bottom wall of the circuit box and located on one side of the single-chip computer, and the networked alarm is electrically connected to the single-chip computer.

[0013] Furthermore, a detachable window-breaking hammer is provided on the outer wall of the box.

[0014] The technical effects achieved by this utility model are:

[0015] This practical fire hydrant intelligent smoke alarm device is equipped with an electromagnet. Only when the smoke sensor and the infrared flame detection sensor detect a fire, the single-chip microcomputer controls the activation of the electromagnet, the horn and the warning emergency light. The activation of the electromagnet will generate magnetic force, which will suck the iron block downward, drive the latch to disengage from the pin hole, and open the door. The alarm button can also be manually controlled to control the activation of the electromagnet to open the door, but at the same time, the horn and the warning emergency light will be activated. In the absence of a fire, the door can be self-locked, which can effectively prevent others from stealing fire water, thereby ensuring the safety and reliability of fire-fighting equipment and providing a solid guarantee for responding to sudden fire incidents.
