Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting and extinguishing, in particular to a self-reactive fire extinguishing sticker. Background Art

[0002] With the development of society, various types of fire extinguishers have emerged one after another. However, most of them, whether portable or fixed, are bulky and fixed in form, making them difficult to place or install in small and complex spaces. Simply reducing the size of the fire extinguisher also makes it difficult to achieve fire extinguishing function. In real life, for example, cable connector protectors, small household distribution cabinets, cable troughs in public places, and so on are prone to fires due to wire overloads or external factors. Fire extinguishing stickers are a new device in the firefighting industry. They are usually installed inside the equipment. When a fire occurs, the internal fire extinguishing composition reacts to extinguish the fire by cooling it and diluting the oxygen concentration. They are small, simple, and low-cost.

[0003] A Chinese patent application, CN117282059A, discloses a fire extinguishing patch comprising a base, a fire extinguishing agent, a trigger, a transmitter, and a temperature sensing component. The base is provided with a cavity, a wire hole, and a plurality of connecting holes, both of which extend from the surface of the base to the cavity. The fire extinguishing agent and the trigger are disposed in the cavity, with the fire extinguishing agent disposed at the trigger end of the trigger, and the trigger and the transmitter are electrically connected. The temperature sensing component comprises a temperature sensing lead and a temperature sensing head, with the temperature sensing lead being disposed in the wire hole, one end of the temperature sensing lead extending into the cavity and connected to the fire extinguishing agent, and the temperature sensing head being connected to the other end of the temperature sensing lead. The transmitter is provided with an independent power supply. When the fire extinguishing agent reacts, the trigger is triggered, and the circuit of the trigger is connected or disconnected, causing the independent power supply to power the transmitter, which in turn causes the transmitter to send a fire signal to a receiving end. The present invention allows personnel to promptly notify personnel of a fire in the equipment, preventing the fire from spreading if the fire extinguishing patch cannot completely extinguish the fire. It also has a wide range of applications and a long service life.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: existing self-reactive fire extinguishing patches only use thermocouples for heat conduction, which makes it impossible to evenly distribute heat to the fire extinguishing agent, resulting in uneven temperatures on the surface of the fire extinguishing agent. As a result, the fire extinguishing composition inside the fire extinguishing agent cannot react simultaneously, resulting in inconsistent dissipation time of the generated fire extinguishing substances, and the concentration of the fire extinguishing substances is relatively low, which reduces the fire extinguishing effect. In addition, it is inconvenient for people to quickly replace the fire extinguishing patch after use. Therefore, a self-reactive fire extinguishing patch is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology, the present invention solves the problem that only using temperature-sensitive wires for heat conduction makes it impossible to evenly distribute heat to the fire extinguishing agent, which causes the surface of the fire extinguishing agent to have different temperatures, and further makes the fire extinguishing composition inside the fire extinguishing agent unable to react at the same time, so that the generated fire extinguishing substances are distributed at inconsistent times, the concentration of the fire extinguishing substances is relatively low, which reduces the fire extinguishing effect, and it is inconvenient for people to quickly replace the fire extinguishing patch after use. The present invention proposes a self-reactive fire extinguishing patch.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: the self-reactive fire extinguishing patch described in the present invention comprises a bottom plate, mounting plates are fixedly connected on both sides of the bottom plate, mounting holes are provided on both sides of the top of the mounting plate, double-sided tape is adhered to the bottom of the mounting plate, a shell is provided on the top of the bottom plate, a smoke sensor is fixedly connected to the top of the shell, a buzzer is fixedly connected to the top of the shell, the buzzer is located on the front of the smoke sensor, first through holes are provided on both sides of the top of the shell, second through holes are provided on the front and back of the shell, a plurality of the first through holes and a plurality of the second through holes are provided, a heat conducting plate is fixedly connected to the inner bottom side of the shell, a fire extinguishing agent is placed on the top of the heat conducting plate, and the two sides of the heat conducting plate are fixedly connected to the sensor Temperature line, one end of the temperature sensing line passes through the inner wall of the shell and is fixedly connected to the temperature sensing head, the inner top wall of the shell is provided with a fixing mechanism, and the inside of the shell is fixedly connected to the battery. First, the bottom plate is fixed to the position where fire protection is required through the mounting plate, and the bottom plate is fixed by using the mounting holes and bolts on the mounting plate. Then, it is clamped in the inside of the card slot through the buckle, so as to fix the shell to the surface of the bottom plate. At the same time, the firmness of the mounting plate and the fixed position can be strengthened by the double-sided tape. When a fire occurs, the heat is conducted to the heat conducting plate through the temperature sensing head and the temperature sensing line, and the heat conducting plate then evenly guides the heat to the fire extinguishing agent, so that the substances in the fire extinguishing agent react to generate fire extinguishing substances. The fire extinguishing substances are emitted to the outside of the shell through the first through hole and the second through hole and extinguish the fire at the fire location.

[0007] Preferably, guide plates are fixedly connected to the inner sides of the shell, and an air collecting hood is fixedly connected to the inner top wall of the shell. The top of the air collecting hood and the first through hole are interconnected. The fire extinguishing material can be distributed to the top side of the shell through the first through hole, and the fire extinguishing material can be distributed to the side of the shell through the second through hole, so that the fire around the fire extinguishing sticker can be extinguished and controlled. The fire extinguishing gas can be conveniently and quickly guided to the first through hole through the air collecting hood, and the fire extinguishing material can be quickly guided to the second through hole through the guide plate, so that the fire extinguishing gas can be quickly dispersed and extinguished, thereby improving the fire extinguishing rate. When a fire occurs, the smoke is sensed by the smoke sensor, and the smoke sensor is wirelessly connected to the buzzer. When the smoke sensor detects smoke, the smoke sensor triggers the buzzer to emit a prompt sound, thereby reminding the staff to further control the fire and facilitating people to replace the fire extinguishing sticker.

[0008] Preferably, the fixing mechanism includes a base plate, the base plate is fixedly connected to the inner top wall of the shell, the bottom of the base plate is fixedly connected to a fixing plate, and the number of the fixing plates is set to be multiple.

The tightening spring is located inside the corrugated shell, and the fire extinguishing agent can be tightly pressed against the surface of the heat conducting plate through the fixing mechanism, preventing the fire extinguishing agent from detaching from the heat conducting plate and being unable to react normally and extinguish the fire, thereby improving the stability of the fire extinguishing patch during use.

[0011] Preferably, a buckle is fixedly connected to the top of the base plate, and a slot is provided on the surface of the shell. The buckle is snapped into the inside of the slot. The arrangement of the buckle and the slot makes it convenient for people to replace the fire extinguishing sticker.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model uses the fixing mechanism and the heat conducting sheet to evenly conduct heat to the surface of the fire extinguishing agent, thereby ensuring the consistency of the surface temperature of the fire extinguishing agent, so that the internal fire extinguishing composition reacts consistently, ensuring that the concentration of the generated fire extinguishing substance is sufficient to extinguish the fire, and improving the fire extinguishing effect. The surrounding of the fire extinguishing agent is fixed by the fixing plate to prevent the fire extinguishing agent from shifting at the position of the heat conducting sheet, and the corrugated shell can be pressed downward by the tightening spring, so that the corrugated shell presses the fire extinguishing agent downward, thereby pressing the fire extinguishing agent tightly against the surface of the heat conducting sheet, preventing the fire extinguishing agent from separating from the heat conducting sheet and failing to react normally and extinguish the fire, thereby improving the stability of the fire extinguishing patch when in use.

[0015] 2. The utility model is provided with a base plate, a mounting plate, a slot and a buckle, etc., and the base plate is fixed to a position requiring long-term fire protection through the mounting plate, and the base plate is fixed by the mounting holes and bolts on the mounting plate.
