Technical field
The utility model relates to a kind of temperature sensing device, particularly a kind of temperature sensing device for diesel locomotive wide area temperature sensing.
Background technology
Along with the high speed development of transportation by railroad, when moving on railway, locomotive in order to satisfy the requirements such as line conditions, natural environmental condition, operating condition, make locomotive need have good performance and adaptive faculty widely.Due to the long-time large load of locomotive, high-frequency running, the hazard level of its breaking out of fire is also high.
For diesel locomotive, the keypoint part of fire prevention and control is diesel oil unit rooms.Diesel engine plays very large effect as the power source of locomotive aspect operation.And diesel engine generates heat because of long time running, and diesel engine indoor oil smoke density is large, thereby has great potential safety hazard.In case diesel engine generation local overheating or because the local circuit loose contact produces spark is easy to cause fire.
At present, adopted infrared ray fire detection system, video monitoring system and smog warning system etc. on a lot of locomotives, be used for the fire prevention and control, but because the car inner structure is complicated, its application has been subject to sizable limitation.Especially for the diesel oil unit room of diesel locomotive, because the condition of work of diesel oil unit room is special, environment is broad and abominable, and existing detection system adaptive faculty is limited, is difficult to satisfy fire prevention and control requirement, still has larger potential safety hazard.
Therefore, how to design a kind of be fit to interior temperature monitoring and overtemperature alarm on a large scale, and has good specific environmental adaptability, can in time find fire, the temperature sensing device that is used for diesel locomotive wide area temperature sensing that people can be adopted an effective measure within the shortest time is present various equivalent modifications problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of temperature sensing device for diesel locomotive wide area temperature sensing is provided, it is simple in structure, easy for installation, temperature monitoring and overtemperature alarm in being fit on a large scale, and have good specific environmental adaptability, can in time find fire, people can be adopted an effective measure within the shortest time, eliminated potential safety hazard.
The technical solution of the utility model is: a kind of temperature sensing device for diesel locomotive wide area temperature sensing, comprise K type armouring Continuous Heat galvanic couple and compensating wire, the two ends of described K type armouring Continuous Heat galvanic couple are connected with respectively a plug, described compensating wire is two, one end of two compensating wires is connected with respectively a socket, and the two ends of described K type armouring Continuous Heat galvanic couple are pegged graft fixing by the socket of plug and each compensating wire respectively.
The junction of described K type armouring Continuous Heat galvanic couple and plug is perfused with fluid sealant; The junction of described compensating wire and socket is perfused with fluid sealant.
Described plug is provided with contact pin, and socket is provided with the jack corresponding with contact pin.
Described contact pin adopts the copper gilding to make.
Described plug and socket all adopts copper nickel plating material to make.
The junction of described plug and socket is provided with O-ring seal.
adopt technique scheme: because this temperature sensing device comprises K type armouring Continuous Heat galvanic couple and compensating wire, the two ends of described K type armouring Continuous Heat galvanic couple are connected with respectively a plug, described compensating wire is two, one end of two compensating wires is connected with respectively a socket, the two ends of described K type armouring Continuous Heat galvanic couple are pegged graft fixing by the socket of plug and each compensating wire respectively, make like this this temperature sensing device can be by the indoor wide area temperature sensing that carries out of K type armouring Continuous Heat galvanic couple combustion motor car diesel engine, thereby realize the situation that excess temperature or fire occur is reported to the police, can in time find fire, people can be adopted an effective measure within the shortest time, eliminated potential safety hazard.Two ends due to K type armouring Continuous Heat galvanic couple are connected with respectively plug simultaneously, have formed redundancy structure, have guaranteed the safety and reliability of product.And peg graft fixingly because K type armouring Continuous Heat galvanic couple and compensating wire adopt, be easy for installation and maintenance.
Because the junction of junction, compensating wire and the socket of K type armouring Continuous Heat galvanic couple and plug is perfused with respectively fluid sealant, can not only reach good waterproof heatproof effect, avoided because of dabble in piggyback pod, water inlet or humidity is excessive etc. causes electric elements short circuit or jitter in this temperature sensing device, and can also play the further fixedly effect of the two poles of the earth and insulation.
Because the contact pin employing copper gilding of plug is made, can guarantee intensity and the decay resistance of contact pin, can reduce contact resistance again.
Make because plug and socket all adopts copper nickel plating material, make it have good salt spray corrosion resistance.
Because the junction of plug and socket is provided with O-ring seal, guaranteed the waterproof effect of the junction of plug and socket.
The utility model is simple in structure for the temperature sensing device of diesel locomotive wide area temperature sensing, easy for installation, temperature monitoring and overtemperature alarm in being fit on a large scale, and has good specific environmental adaptability, can in time find fire, people can be adopted an effective measure within the shortest time, eliminated potential safety hazard.
