Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a fire extinguishing device linked with an explosion relief plate. Background Art

[0002] Explosion vents are safety devices used to protect equipment, pipelines, and containers. They automatically open when the internal pressure of the system exceeds a predetermined level. In the event of an explosion, the vent wall quickly opens, directing the blast wave to a safe area, mitigating damage and injury. Their specific features include: 1. They act as a barrier to limit and control the spread of explosive energy, protecting personnel and equipment. 2. They prevent the spread of flames: Flames are another significant threat in explosions. Explosion vents release explosive energy by opening and then direct the flames to a safe area, preventing their spread. 3. They effectively control the spread of fire, minimizing damage to the surrounding environment and equipment, and improving firefighting effectiveness. While explosion vents can limit the spread of explosive energy, when installed in an enclosure (such as an electrical control box or power panel), they cannot extinguish the flames if an electrical appliance within the enclosure catches fire. Furthermore, the explosion generates significant internal energy, which can impact surrounding objects and the environment as it is channeled outward. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of a fire extinguishing device linked with an explosion relief plate;

[0014] Figure 2 for Figure 1 Schematic diagram of the internal structure of a fire extinguisher. DETAILED DESCRIPTION

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 and 2 As shown, a fire extinguishing device linked to an explosion venting plate includes a fire extinguisher 2 arranged in a box body 1, an explosion venting hole is opened on the side of the box body 1, an explosion venting plate 3 is installed at the position of the explosion venting hole, and a hollow mesh bracket 4 fixedly connected to the side of the box body 1 is provided in the outer area of ​​the explosion venting plate 3. A piezoelectric ceramic 5 is fixedly provided at a position opposite to the explosion venting plate 3 on the inner side of the hollow mesh bracket 4. The piezoelectric ceramic 5 is connected to the electric ignition head 2.1 in the fire extinguisher 2 through an electric starting line 6.

[0017] Preferably, the fire extinguisher 2 is an aerosol fire extinguishing device.

[0018] Preferably, the fire extinguisher 2 includes a housing 2.2 fixedly connected to the inner side of the housing 1. An aerosol generator 2.3 is disposed within the housing 2.2. The end of the aerosol generator 2.3 contacts the electric ignition head 2.1, and a nozzle 2.4 is disposed at the end of the housing 2.2. More preferably, when the fire extinguisher 2 utilizes an aerosol fire extinguishing device, a coolant is disposed in the region of the housing 2.2 between the aerosol generator 2.3 and the nozzle 2.4 to cool the high-temperature fire extinguishing agent generated by the aerosol generator 2.3 and prevent the nozzle 2.4 from overheating.

[0019] Preferably, the electric ignition head 2.1 is a bridgeless ignition head structure. In this embodiment, the electric ignition head 2.1 adopts a bridgeless ignition head. Since there is a certain gap between the two ignition wires of the bridgeless ignition head, arcing will occur after providing a certain current or induced current to activate the aerosol generating agent 2.3.

[0020] Preferably, the electric ignition head 2.1 is embedded within an ignition powder pack 2.5, which contains aerosol generating agent powder. In this embodiment, the ignition powder pack 2.5 serves as a priming agent, enclosing the electric ignition head 2.1. Upon activation of the electric ignition head 2.1, the aerosol generating agent powder within the ignition powder pack 2.5 ignites, rapidly generating heat that ignites the nearby aerosol generating agent 2.3, significantly increasing the probability of successful activation of the electric ignition head 2.1.

[0021] Preferably, the aerosol generator 2.3 is a powdered aerosol generator or a compressed aerosol generator powder. The aerosol generator 2.3 can be in two forms: a powdered form that burns more vigorously and produces gas quickly, and a compressed form that burns more smoothly and produces gas at a steady rate. In actual production, the preferred form can be selected based on actual conditions.

[0022] Preferably, a protective diaphragm is provided on the surface of the nozzle 2.4. The protective diaphragm prevents moisture in the air from entering the housing 2.2 through the nozzle 2.4 and causing the aerosol generating agent 2.3 to absorb moisture. Furthermore, during the fire extinguishing process, when the air pressure inside the housing 2.2 increases, the protective diaphragm is easily broken through, without affecting the normal spraying process of the nozzle 2.4.

[0023] The working principle of this embodiment is as follows:

[0024] When a fire or explosion occurs within housing 1, enormous internal energy is generated within housing 1. This energy forces the explosion venting plate 3 to break open, releasing the energy generated by the flame and explosion through the hollowed-out portion of the hollow mesh support 4. Once the explosion venting plate is broken open, it collides with the piezoelectric ceramic 5, which activates and generates an induced current. This current is conducted through the activation wire 6 to the electric ignition head 2.1, causing it to operate. This ignites the aerosol generating agent 2.3 within the fire extinguisher 2, completing the activation process. This allows the fire extinguisher within the housing to activate spontaneously without external assistance. The aerosol generating agent 2.3 burns to produce a fire extinguishing substance, thus extinguishing the fire.

[0025] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The embodiments and features therein may be arbitrarily combined unless they conflict. The scope of protection of the present invention shall be the technical solutions described in the claims, including equivalent alternatives to the technical features of the technical solutions described in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
