Description

Technical Field

[0001] This utility model relates to the field of power-off device technology, and in particular to a power-off device combined with a gas generating device. Background Technology

[0002] In the event of an electrical fire, people often make mistakes in their operations due to tension and panic. For fires that are small and cover a small area, fire-fighting equipment can be used on-site to extinguish the fire and disconnect the power supply closest to the fire source. When disconnecting the power supply, the circuit breaker must be turned off first, and then the isolating switch or knife switch must be turned off. The steps are relatively cumbersome and somewhat dangerous. When the fire is very intense and there is no time to turn off the power supply with a switch, the wire can be cut short or the wire can be made to be de-energized. However, there is also a great danger in the process of cutting the power supply. Therefore, how to ensure life safety and achieve timely and effective power disconnection is a big problem.

[0003] With the continuous development of society, the types and quantities of electrical appliances are gradually increasing. Most electrical appliances need to remain in a standby state for extended periods while in operation. These appliances generate high temperatures when powered on, and as they age, they are highly susceptible to electrical fires. In addition to timely firefighting, the power supply should be immediately cut off after an electrical fire breaks out. Attempting to extinguish a fire while the electrical equipment is powered on is not only more difficult, but also carries the risk of electric shock and electrical explosions for firefighters.

[0004] In real-world scenarios, electrical fires can escalate to large scale, making it difficult or impossible to cut off the power in time, which greatly complicates firefighting efforts. Utility Model Content

[0007] Preferably, the H-shaped conductive slider is interference-fitted with the inner side of the housing.

[0008] Preferably, a stop is fixedly provided on the inner side of the housing at the position where it contacts the H-shaped conductive slider.

[0009] Preferably, the gas generating device comprises a shell and a gas generating agent arranged in the shell, one end of the gas generating agent is connected with the starting component, a spray hole is arranged on the surface of the shell, and the spray hole faces one end of the H-shaped conductive sliding block.

[0011] More preferably, the starting component is a thermal sensitive wire structure or an electric starter structure.

[0018] The utility model will be described in further detail in combination with the drawings and specific embodiments.

[0019] As shown in Figures 1-3 , a power-off device combined with a gas generating device comprises a shell 1, the shell 1 comprises an insulating ring 3 located in the middle region, the insulating ring 3 is connected with a conductive end cover 5 through a conductive ring 4 on both sides, the conductive end cover 5 is connected with an electric wire 2, the shell 1 is provided with an H-shaped conductive sliding block 6 matched with the shell 1, the H-shaped conductive sliding block 6 is in contact with the inner side of the conductive ring 4 on both ends, and a gas generating device 7 is arranged in the cavity between one end of the H-shaped conductive sliding block 6 and the conductive end cover 5.

[0020] When a fire does not occur, the H-shaped conductive sliding block 6 cannot slide in the shell 1, and the H-shaped conductive sliding block 6 can be limited through the following two implementation modes.

[0021] In the embodiment, when the starting component ignites the aerosol generating agent in the gas generating device 7, aerosol fire extinguishing material is generated and sprayed out of the spray hole to generate a pushing force on one end of the H-shaped conductive sliding block 6. After the H-shaped conductive sliding block 6 moves, one end of the H-shaped conductive sliding block 6 contacts the insulating ring 3, thereby achieving the purpose of breaking the circuit.

[0022] In the embodiment, as shown in the figure, a stopper 8 is fixedly arranged at a position where the inner side of the shell 1 contacts the H-shaped conductive sliding block 6. The stopper 8 can block the H-shaped conductive sliding block 6. When a sufficient pushing force is generated on one side of the H-shaped conductive sliding block 6, the H-shaped conductive sliding block 6 breaks through the stopper 8 and smoothly slides in the shell 1. Figure 3

[0023] Preferably, the gas generating device 7 comprises a shell and a gas generating agent arranged in the shell. One end of the gas generating agent is connected to the starting component. A spray hole is arranged on the surface of the shell and faces one end of the H-shaped conductive sliding block 6.

[0024] More preferably, the gas generating agent is an aerosol generating agent.

[0025] In the embodiment, when the starting component ignites the aerosol generating agent in the gas generating device 7, aerosol fire extinguishing material is generated and sprayed out of the spray hole to generate a pushing force on one end of the H-shaped conductive sliding block 6. After the H-shaped conductive sliding block 6 moves, one end of the H-shaped conductive sliding block 6 contacts the insulating ring 3, thereby achieving the purpose of breaking the circuit.

[0026] More preferably, the starting component is a heat-sensitive wire structure or an electric starter structure. When the starting component is a heat-sensitive wire structure, the heat-sensitive wire can be directly ignited by a flame in the event of a fire, thereby igniting the aerosol generating agent in the gas generating device 7. When the starting component is an electric starter structure, it comprises an electronic ignition head and a starting wire harness. One end of the electronic ignition head contacts the aerosol generating agent, and one end of the starting wire harness is connected to the electronic ignition head and the other end passes through a wire hole and is connected to an external power source. When the starting component is an electric ignition head structure, it further comprises a fire detection device, which is a temperature sensor and / or a smoke sensor. When a fire, overheating or other situation occurs, the fire detection device detects a high-temperature environment generated by the fire outside and sends a signal to a microprocessor. The microprocessor controls the external power source to work, thereby igniting the electronic ignition head and igniting the aerosol generating agent.

[0027] Preferably, the surface of the shell 1 is further provided with a gas pressure balancing hole 9. The gas pressure balancing hole 9 has two functions. One is to ensure the smooth movement of the H-shaped conductive sliding block 6, otherwise the gas pressure may hinder the movement of the H-shaped conductive sliding block 6. The other is to prevent the internal pressure of the shell 1 from being too high due to excessive gas generated by the gas generating device 7, thereby preventing the risk of explosion.​

[0028] The working principle of this embodiment is as follows:

[0029] like Figure 3 As shown, when no fire occurs, both ends of the H-shaped conductive slider 6 are in contact with the inner side of a conductive ring 4, so that the wires 2 at both ends of the outer casing 1 are connected in sequence through one conductive end cap 5, one conductive ring 4, H-shaped conductive slider 6, the other conductive ring 4 and the other conductive end cap 5, and the entire circuit is connected at this time. When a fire occurs outside, when the starting component ignites the aerosol generator in the gas generating device 7, it can generate aerosol fire extinguishing material, which is sprayed out from the discharge hole and generates a thrust on one end of the H-shaped conductive slider 6. After the H-shaped conductive slider 6 moves, one end of the H-shaped conductive slider 6 contacts the insulating ring 3, so that the wires 2 at both ends of the outer casing 1 are not connected to each other, and the entire circuit achieves the purpose of breaking the circuit.

[0030] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
