Abstract
The present utility model relates to a power supply socket for preventing electric appliance fire hazards. A socket box is provided with a mechanical type pressure switch, a pressure switch normally opened contact is connected in parallel between an AC power supply live wire and a live wire jack, one end of a polymer flexible pipe is connected with a pressure switch control mouth, the other end is connected with an inflation non-return valve, the polymer flexible pipe is arranged inside an electric appliance and filled with extinguishing chemical and pressurizing gas for fighting electric appliance fire hazards, and the flexible pipe or the non-return valve is connected with a gas-pressure meter. When the temperature of a certain fire hazard dangerous source inside the electric appliance reaches the softening and explosion temperature of the adjacent polymer flexible pipe, the extinguishing chemical inside the flexible pipe will spray out and effectively cover the dangerous source, thus abnormal temperature rise inside the electric appliance can be reduced, and initial fire hazards can be put out rapidly. At the same time, control pressure of the pressure switch is lost, the contact is broken immediately and a main power supply is cut off. In the power supply socket, fire hazard detection, fire extinguishing and power supply interruption are integrated, and fire hazard detection is timely and reliable and fire extinguishing is rapid and accurate.
Description
Technical field
The utility model belongs to supply socket, particularly relates to a kind of supply socket that prevents appliance fire.
Background technology
Along with the continuous increase of constantly the popularizing of China's electric power, power consumption equipment, the appliance fire that is caused by power consumption equipment superpressure, overburden or short circuit is more and more.According to the fire department statistics, appliance fire has become one of most important cause of fire, and all can cause a large amount of economy and property loss to country every year, so the protection of appliance fire has become the significant challenge that China security against fire field faces.
At present; The device that in electrical equipment, is used for ultra-voltage, supercurrent or short-circuit protection mainly is overload protective device, short-circuit protector and earth leakage protective device etc.; These protection devices all are when overcurrent or overvoltage phenomenon appear in electrical equipment or power circuit, to avoid fault further to enlarge with the mode of cutting off the electricity supply, but then do not have the function of in time putting out for the initial fire disaster that causes because of said fault.
Existing fire-fighting system comprises localised protection fire extinguishing system and total flooding extinguishing system, but these fire extinguishing system general costs are higher, are not suitable for common power consumption equipment.Pony is the fire-fighting equipment that is applicable to that family or general place are equipped with; But pony can't play a role during for frequent unattended charged electrical equipment generation appliance fire, or usually can't in time put out the initial stage that maybe can not be controlled at fire for the appliance fire that has taken place.
Summary of the invention
The purpose of the utility model is to disclose a kind of supply socket that prevents appliance fire, and this supply socket has can in time be surveyed the superthermal or initial fire disaster of electrical equipment, cuts off the power supply automatically and put out the characteristics of initial fire disaster.
The utility model is taked following technical scheme for realizing above-mentioned purpose: the supply socket of this prevention appliance fire comprises socket box; Characteristic is; Socket box is provided with the mechanical compression switch, is in series with the normally opened contact of mechanical compression switch between AC power live wire and the socket box firewire jack, and polymer flexible pipe one end that big of main body is arranged in the electrical equipment is connected with mechanical compression switch pressure control input port; The other end is provided with the inflation unidirectional valve; Said polymer flexible pipe is filled with and is suitable for the extinguishing chemical and the pressurized gas of putting out a fire to save life and property appliance fire, and pressurized gas pressure is 0.6-2.0Mpa, and said polymer flexible pipe or inflation unidirectional valve are connected with air gauge.
The utility model can also be taked following technical measures:
Said polymer flexible pipe is that fire-fighting system is with thalposis fire extinguishing tube or fiery inserting tube.
Said polymer flexible pipe is connected with the extinguishing chemical storage tank jar mouth valve outlet port of the appliance fire that is suitable for putting out a fire to save life and property.
The extinguishing chemical of the said appliance fire that is suitable for putting out a fire to save life and property is a kind of of clean gas extinguishing chemical, especially heptafluoro-propane or HFC-236fa or fluoroform or fluorinated ketone or monobromo trifluoro propene, and its pressurized gas is nitrogen or carbon dioxide.
The extinguishing chemical of the said appliance fire that is suitable for putting out a fire to save life and property is a ultra-fine dry powder extinguishing agent, and its pressurized gas is nitrogen or carbon dioxide.
The beneficial effect and the advantage of the utility model are: the employed polymer flexible pipe of this supply socket is that fire-fighting fire extinguishing has performance characteristics such as long-term anti-leakage property, resistance to pressure, response to temperature and pliability with thalposis fire extinguishing tube or fiery inserting tube, and is filled with the extinguishing chemical of certain pressure in inside.When the temperature in the inner somewhere of electrical equipment reached the explosion temperature of adjacent polymeric thing flexible pipe, extinguishing chemical ejection and effective covering initial stage burning things which may cause a fire disaster that being suitable in the polymer flexible pipe puted out a fire to save life and property appliance fire not only can put out initial fire disaster and also can reduce the electrical equipment temperature inside.Meanwhile, because the explosion of polymer flexible pipe, the mechanical compression switch has lost controlled pressure, and its normally opened contact is reverted to the disjunction state immediately and cut off the electrical equipment general supply by engagement state.The utility model integrates detection, puts out a fire and cuts off the electricity supply, and has in time reliable, the outstanding accurately rapidly advantage of putting out a fire of detection.
