Description

Technical Field

[0001] The present invention relates to the technical field of fire alarm platforms, and in particular to an intelligent fire alarm device for buildings. Background Art

[0002] Fire alarm devices are detection and alarm devices in fire alarm systems that can identify and warn of fires. Currently, smoke sensors, temperature sensors, flame detectors, and other devices are commonly used to monitor signs of fire in the environment in real time. Once an abnormality is detected, such as an increase in smoke concentration or a rapid rise in temperature, the system will immediately sound an alarm. However, when a fire occurs in a building, current fire alarm devices can only sound an alarm and cannot guide residents of other rooms in the building to evacuate in an orderly manner based on the floor and room number of the fire room. After receiving the alarm, all users in the building will be easily confused in the safe passage due to the anxiety of escaping, which greatly increases the probability of stampedes and causes unnecessary casualties.

[0003] For example, the intelligent fire alarm device for buildings disclosed in Publication No. CN114639211B can increase the visibility of the alarm signal in thick smoke when a fire occurs. However, in the early stages of the alarm, the smoke in the building is not thick, and the chaos caused by the disorderly evacuation of residents is difficult to avoid.

[0018] The present invention provides an intelligent fire alarm device for buildings. Compared with the prior art, it has the following advantages:

[0019] (1) The intelligent fire alarm device for a building is provided with an alarm body, a signal line, a split box, an indicator board, and a battery compartment. By installing the alarm body in a room, when a fire occurs in the room, the alarm body transmits the alarm signal to the property control room, and transmits the alarm signal to the local fire department through the property control room, and at the same time transmits the alarm signal to the split box in the adjacent room of the room where the fire occurs, and controls the indicator board on the top of the split box to light up, indicating the floor where the fire is found and the escape direction. The arrow on the indicator board points to the direction of the nearest safe passage from the current room and lights up an exclamation mark. According to the location of the fire room in the building and the distance from other rooms, the residents in the building can be prompted to evacuate quickly and orderly from the corresponding safe passage, thereby reducing casualties and avoiding the chaos caused by the residents rushing to the safe passage, resulting in unnecessary casualties and reducing the evacuation speed of the residents in the safe passage.

[0020] (2) The intelligent fire alarm device for buildings is provided with a fixed electromagnet, a moving electromagnet, a slide rail, a spring, a sliding rod, a sliding push block, a sliding push plate, a sliding block, a support shaft, a baffle, a limit plate, a water storage bottle, and a storage box. When the alarm body issues a fire alarm and the yellow light or red light is always on, the property control room will cut off the power supply to the floors where the rooms with the yellow light or red light are located to avoid further spread of the fire due to short circuit of the wires. At this time, the battery in the battery compartment will be used for power supply, and the emergency response mode will be entered at the same time. The sliding rod will be squeezed and moved by the magnetic attraction and mutual repulsion of the fixed electromagnet and the moving electromagnet. The sliding block flips and increases the flip angle of the baffle. The opening of the water bottle is larger, and the water can flow into the storage box more quickly, soaking the cloth in the storage box. At this time, the resident can take out the soaked cloth from the storage box, cover his mouth and nose, and quickly move to the safe passage indicated by the arrow. When a fire occurs, it can intelligently select the appropriate split box to enter the emergency response mode, and provide the soaked cloth to the residents of the room where the split box is located in a short time without the need for the residents to operate themselves. This saves time leaving the fire scene while improving safety during the departure process, and avoids health problems caused by inhaling too much smoke during the escape process.

[0021] (3) The intelligent fire alarm device for buildings is provided with a fixed storage board, a dynamic storage board, a guide rod, a limit rod, a fixed rod, a sliding sleeve, a telescopic rod, a rotating seat, a cover plate, a movable shaft, a gear, a rack, a floating plate, a support rod, an extrusion rod, a sliding plate, a positioning rod, and a spring. When the split box enters the emergency response mode, the number of storage components in the storage box is equipped according to the number of residents in the room, and the water in the water bottle flows into the storage box and flows through the water flow holes opened on the surface of the upper fixed storage board and the dynamic storage board to the cloth block of the lower layer until the water in the water bottle is completely drained and the dynamic storage board is used. The storage board extends from the fixed storage board to the outside of the storage box, so that the soaked cloth is extended to the outside of the storage box for the resident to take out. When the baffle is reset, the sliding plate is reset to the initial state under the action of spring 2, so that the storage component with the cloth placed again is retracted into the storage box again to wait for the next use. The soaked cloth can be extended from the storage box as soon as the water in the water bottle is drained, which is convenient for the resident to take out, reducing the preparation time for the resident to escape from the fire scene, saving the time of leaving the fire scene and improving the safety during the departure process, avoiding the resident from inhaling too much smoke during the escape and causing health problems.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figures 1 to 10 , the present invention provides the following technical solutions:

[0035] Embodiment 1: An intelligent fire alarm device for a building comprises an alarm body 1 and a signal line 101 fixedly mounted on the alarm body 1. The alarm body 1 is electrically connected to a split box 102 via the signal line 101. A battery compartment 104 is fixedly mounted in the split box 102. A group of batteries can be detachably mounted in the battery compartment 104. An indicator sign 103 is fixedly mounted on the top of the split box 102. The indicator sign 103 is provided with an arrow for guiding the direction of escape, an exclamation mark for indicating the floor of the room where the fire occurs, and an emergency situation indicating the current location.

[0036] When in use, by installing the alarm body 1 in a room, when a fire occurs in the room, the alarm body 1 transmits the alarm signal to the master control system in the property control room through the signal line 101, and the alarm signal is transmitted to the local fire brigade through the master control system and is also transmitted to the split box 102 in each room in the building, and the indicator sign 103 on the top of the split box 102 is controlled to light up, indicating the floor where the fire is found and the escape direction. The arrow on the indicator sign 103 points to the direction of the nearest safe passage from the current room, and an exclamation mark is lit;

[0037] When the exclamation mark is always green, it indicates that the fire room is far away from the current room or the fire is small, prompting people to evacuate in an orderly manner;

[0038] When the exclamation mark flashes yellow, it indicates that the fire room is at a moderate distance from the current room or the fire is spreading, prompting personnel to evacuate as soon as possible;

[0039] When the exclamation mark is always yellow, it indicates that the fire is in an adjacent room on the same floor as the current room, prompting personnel to use the firefighting facilities in the building to help extinguish the fire;

[0040] When the exclamation mark is flashing red, it indicates that there is a fire in the room and the personnel in the room can use the fire-fighting facilities in the building to extinguish the fire;

[0041] When the exclamation mark is solid red, it indicates that the fire is difficult to control and prompts people to evacuate as soon as possible and wait for professional firefighters to arrive. At the same time, the room with the exclamation mark yellow will also change to solid red.

[0042] The people in the rooms above the room where the fire occurred can receive the news in time and evacuate as soon as possible to reduce casualties. After receiving the news, the people in the adjacent rooms on the same floor can immediately use the fire-fighting facilities in the building to assist the people in the room where the fire occurred in extinguishing the fire. The time interval for notifying the residents of different floors is set according to the distance and danger level of the fire room, and the residents in the building are guided to different safe passages in the building to divert the fleeing crowd, so as to avoid the residents of all floors from rushing to the safe passages, causing chaos and unnecessary casualties.

[0043] When the fire in the room where the fire occurred is effectively controlled, the smoke and temperature parameters measured in the fire room and the surrounding areas by the alarm body 1 located on the same floor and above the fire room are transmitted to the property control room. The property control system determines whether the parameters are on an upward or downward trend, and decides whether to cancel the alarm information sent to the local fire department.

One end of the support shaft 28 is movably provided in the water storage bottle 211 through a bearing. The top of the water storage bottle 211 is fixedly mounted on the side wall of the split box 102 through a mounting plate.

[0048] A spring 23 is fixedly installed on the side wall of the moving electromagnet 21, and the other end of the spring 23 is fixedly installed on the side wall of the slide rail 22 away from the fixed electromagnet 2. One end of the sliding rod 24 slides out of the slide rail 22 and the split box 102 in turn. The side wall of the storage box 3 is fixedly installed on the side wall of the split box 102 through the mounting column, and the storage box 3 is connected to the water storage bottle 211.

[0049] When in use, when the alarm body 1 issues a fire alarm and the yellow light or red light is on, the property control room will cut off the power supply to the floors where the rooms with the yellow light or red light are located to prevent the fire from spreading further due to short circuits or other reasons;

[0050] At this time, the battery in the battery compartment 104 will supply power, and the emergency response mode will be entered at the same time.
