Abstract
The invention provides a boiler fume temperature probe with a displacement monitoring device. A barrel supporting wheel (2) and a barrel pressing wheel (4) are respectively arranged at one end of a fume temperature probe beam body (1); one end of a probing gun (8) is arranged on a running vehicle (9), and the other end of the probing gun (8) is positioned between the barrel supporting wheel (2) and the barrel pressing wheel (4); the running vehicle (9) is positioned on a rail arranged in the beam body (1); a magnetic steel head (11) is arranged at one side of the running vehicle (9); a magnetic displacement sensor (10) is arranged inside the fume temperature probe beam body (1); the signal output end of the magnetic displacement sensor (10) is electrically connected with the signal input end of a secondary meter. The boiler fume temperature probe has the advantages that after a drag chain mechanism replaces a wheel train mechanism, the corrosion and cable fracturing phenomenon of the wheel train mechanism can be avoided; as the magnetic displacement sensor adopts the full sealing design, the sleeve is made from stainless steel, by adopting the structure, the corrosion can be effectively avoided; the anti-interference performance is strong; the stable and reliable displacement data can be obtained.
Description
Technical field
The present invention relates to boiler smoke temperature sniffer field, be specifically related to a kind of boiler smoke temperature probe with displacement monitor.
Background technology
At present, existing boiler smoke temperature probe is all moved by thermopair and will survey at different warm area, the dynamic position of temperature probe is the 10 circle variable resistors by being arranged on body, being driven by the gear mechanism on sport car makes it rotate the different resistances of acquisition, the dynamic position of its temperature probe is reacted by secondary instrument, this gear mechanism is owing to being subject to the restriction of working condition, the dragging wirerope in its gear mechanism is easy to produce corrosion, be arranged on compensation lead of thermocouple in gear mechanism and the motor line of force is also easy to produce be full of cracks under the effect of its deadweight, therefore failure rate is high, maintenance difficult.
Summary of the invention
Object of the present invention is exactly the deficiency of the technical defect for current existing boiler smoke temperature probe existence, and a kind of boiler smoke temperature probe with displacement monitor of invention.
The present invention includes cigarette temperature probe bodies, cigarette temperature probe bodies mainly comprises cigarette temperature probe beam body, gun barrel support roller, envelope wall case, gun barrel pinch roller, sub-control box, master control box, towing chain mechanism, visit rifle, magnetic displacement transducer, magnet steel head, sport car and travel switch, gun barrel support roller and gun barrel pinch roller are arranged on cigarette temperature probe beam body one end respectively, sub-control box and master control box are arranged on the external side of cigarette temperature probe beam respectively, towing chain mechanism is arranged in cigarette temperature probe beam body by dee, and two ends are separately fixed on dee and sport car, visiting rifle one end is arranged on sport car, the other end is between gun barrel support roller and gun barrel pinch roller, sport car be positioned at that beam body is provided with track on, it is characterized in that it also has displacement monitor, displacement monitor comprises magnetic displacement transducer, magnet steel head and secondary instrument, magnet steel head is arranged on sport car side, and magnetic displacement transducer is arranged on inside cigarette temperature probe beam body, and the signal output part of magnetic displacement transducer is electrically connected with the signal input part of secondary instrument.
Advantage of the present invention is: this device mainly adopts magnetic displacement transducer to substitute former 10 circle variable resistors, adopts towing chain mechanism to substitute former gear mechanism.Towing chain mechanism avoids corrosion and the cable crack performance of gear mechanism after replacing gear mechanism, due to magnetic displacement transducer employing is hermetically sealed design, sleeve pipe is stainless steel, and this structure corrodes outer strong interference immunity except can effectively avoid, and can obtain reliable and stable displacement data.

Embodiment
As shown in Figure 1, the present invention includes cigarette temperature probe bodies, cigarette temperature probe bodies mainly comprises cigarette temperature probe beam body 1, gun barrel support roller 2, envelope wall case 3, gun barrel pinch roller 4, sub-control box 5, master control box 6, towing chain mechanism 7, visit rifle 8, magnetic displacement transducer 10, magnet steel head 11, sport car 9 and travel switch 12, gun barrel support roller 2 and gun barrel pinch roller 4 are arranged on cigarette temperature probe beam body 1 one end respectively, sub-control box 5 and master control box 6 are arranged on outside cigarette temperature probe beam body 1 respectively, towing chain mechanism 7 is arranged in cigarette temperature probe beam body 1 by dee, and two ends are separately fixed on dee and sport car 9, visiting rifle 8 one end is arranged on sport car 9, the other end is between gun barrel support roller 2 and gun barrel pinch roller 4, sport car 9 be positioned at that beam body 1 is provided with track on, it is characterized in that it also has displacement monitor, displacement monitor comprises magnetic displacement transducer 10, magnet steel head 11 and secondary instrument, magnet steel head 11 is arranged on sport car 9 side, and magnetic displacement transducer 10 is arranged on inside cigarette temperature probe beam body 1, and the signal output part of magnetic displacement transducer 10 is electrically connected with the signal input part of secondary instrument.
Principle of work: sport car 9 drives spy rifle 8 and magnet steel head 11 to move back and forth, the electric current making the change in resistance of magnetic displacement transducer 10 produce under the effect of magnetic force converts data-signal by secondary instrument to current signal, be arranged on the thermal sensor (thermopair) visited in rifle 8 and temperature signal is converted to electromotive force signal, then convert the temperature of measured medium to by secondary instrument.Direct reading displacement number or teletransmission are to data collection point.
Sport car 9 drives magnet steel head 11 to move relative to " magnetic inductor 10 " be fixed on beam body 1, because the effect in magnetic field converts the position signalling of ' magnetic head ' to current signal (4-20mA), directly read shift length or teletransmission to data collection point by secondary instrument.
