Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a blade circuit breaker device combined with a gas generating device. Background Art

[0002] After an electrical fire occurs, due to tension and panic, people often have accidents in operation. For fires with smaller fires and smaller fire areas, fire-fighting equipment can be used on the spot to extinguish the fire and disconnect the power supply close 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 can be cut off. The steps are relatively cumbersome and have certain risks. When the fire is very fierce, there is no time to cut off the power supply with a switch. At this time, the wires can be shortened or the wires can be made to have no power. However, there will be greater danger in the process of cutting off the power supply. Therefore, how to relatively ensure life safety and be able to cut off power in a timely and effective manner is a big problem.

[0003] With the continuous development of society, the types and quantity of various electrical appliances are gradually increasing. Most electrical appliances need to be kept in a long-term standby state when working. Electrical appliances will generate high temperatures when powered on. As electrical appliances age, they are very likely to cause electrical fires. In addition to timely extinguishing the fire after an electrical appliance catches fire, the power supply should be cut off immediately. If the fire is extinguished when the electrical equipment is powered on, it will be difficult to extinguish the fire, and it is easy for people to get electric shocks and electrical appliances to explode during the rescue process.

[0004] In actual scenarios, electrical fires may cause large fires, making it difficult or impossible to cut off power in time, which greatly increases the difficulty of firefighting. Utility Model Content

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-2 As shown, a blade circuit breaker device combined with a gas generating device comprises a housing 2 and a blade device 3 arranged in the housing 2, wherein a positioning groove 6 cooperating with the electric wire 4 is provided in the housing 2, and the blade device 3 comprises a cutter 3.1, wherein the cutter 3.1 is slidably matched with a cavity 2.2 provided in the housing 2, and a gas generating device 1 is provided on the top of the cutter 3.1, and the bottom of the cutter 3.1 is opposite to the positioning groove 6.

[0021] Preferably, the cutter 3.1 is hollow inside and is provided with a compression spring 3.2, the top of the compression spring 3.2 is connected to the top of the cutter 3.1, the bottom of the compression spring 3.2 is connected to a fixing block 3.3, and the fixing block 3.3 is fixed in the housing 2. When there is no fire, the compression spring 3.2 can support the cutter 3.1 to prevent it from moving downward.

[0022] Preferably, the lower end of the cutter 3.1 is a pointed structure.

[0023] Preferably, a block 5 is provided inside the cavity 2.2, and a sliding plate 3.1.1 is provided on the top of the cutter 3.1, and the sliding plate 3.1.1 is slidably matched with the inner wall of the cavity 2.2. The block 5 can limit the position of the cutter 3.1 moving toward the positioning groove 6 to prevent the cutter 3.1 from moving out of the positioning groove 6.

[0024] Preferably, the gas generating device 1 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, and a spray hole 1.1 is opened at the bottom of the shell, and the spray hole 1.1 is aligned with the sliding plate 3.1.1.

[0025] Preferably, the gas generating agent is an aerosol generating agent.

[0026] In this embodiment, when the aerosol generating agent is ignited to generate aerosol, it can be ejected from the ejection hole 1.1 to generate thrust on the sliding plate 3.1.1, thereby pushing the entire cutter 3.1 downward to cut off the wire 4 in the positioning groove 6, thereby achieving the purpose of circuit breaking.

[0027] Preferably, a cover body 2.1 is detachably connected to the top of the shell 2, and a threading hole 2.1.1 is opened on the surface of the cover body 2.1, and the threading hole 2.1.1 is used to pass the starting wire harness of the starting component.

[0028] Preferably, the starting component is a thermistor structure or an electric starter structure. When the starting component is a thermistor structure, when a fire occurs in the outside world, the flame can directly ignite the thermistor, thereby igniting the aerosol generator in the gas generating device 1. When the starting component is an electric starter structure, it includes an electronic ignition head and a starting harness. The electronic ignition head contacts one end of the aerosol generator, one end of the starting harness is connected to the electronic ignition head, and the other end passes through the threading hole 2.1.1 to connect to the external power supply; when the starting component is an electric ignition head structure, it is also provided with a fire detection device, which is a temperature sensor and / or a smoke sensor. When a fire, overheating, etc. occurs, the fire detection device detects that the high temperature environment is generated by the fire outside, and sends a signal to the microprocessor. The microprocessor controls the external power supply to work, so that the electronic ignition head ignites, and then the aerosol generator is ignited.

[0029] Preferably, the cutter 3.1 is made of insulating material. With such a design, when the cutter 3.1 cuts the electric wire 4, the power-off process will not fail due to the conduction of the cutter 3.1.

[0030] In addition, preferably, the side of the shell 2 is also provided with an air outlet, so that when a fire occurs, the pressure inside the cavity 2.2 can be released after the pressure increases, and aerosol fire extinguishing substances can also be discharged to achieve a certain fire extinguishing function.

[0031] The working principle of this embodiment is as follows:

[0032] When a fire occurs outside, the starting component ignites the aerosol generating agent in the gas generating device 1, thereby generating aerosol fire extinguishing material; the aerosol fire extinguishing material is ejected from the ejection hole 1.1 and generates thrust on the sliding disk 3.1.1, thereby pushing the entire cutter 3.1 downward to cut off the wire 4 in the positioning groove 6, thereby achieving the purpose of circuit breaking.
