Wireless signal transmitter 22 passes data to intelligent terminal in real time, convenient for related personnel timely to detection case.
It is transmitted in real time to processor 13 specifically, just receiving device 19 by probe signal in moving process due to probe 11
Information proves that oil and gas pipeline has breakage herein, needs maintenance personnel to safeguard in time, still when magnetic field varies widely
A region substantially can only be known at present, can not be learnt accurate location, be not easy to maintenance personnel and oil and gas pipeline is safeguarded,
In order to overcome the above problem, fluorescent pigment box 23, the fluorescent pigment box and spray is arranged in 1 side of shell described in the present embodiment
One end connection of pipe 24 is penetrated, the other end of the injection pipe 24 is arranged spray head 25, jet pump is arranged on the injection pipe 24
26, the jet pump 26 and injection pump controller 27 are electrically connected, and the injection pump controller 27 and processor 13 are electrically
Connection, the processor 13 and GPS module 28 are electrically connected.Device 19 is just received by probe signal when processor 13 and receives spy
When the information that first 11 magnetic fields sent vary widely, processor 13, which controls power wheel 9 by power wheel controller 17, to be stopped
Rotation, the accurate coordinate of this position that simultaneous processor 13 is positioned GPS module 28 by wireless signal transmitter 22 is by information
Intelligent terminal 34 is passed to, simultaneous processor 13 opens the Oil/Gas Pipe that jet pump 26 is safeguarded in needs by injection pump controller 27
Spraying fluorescent pigment in road has effectively saved the time consequently facilitating maintenance personnel searches and maintenance.
Specifically, since when being moved to tube coupling, pipe diameter measuring appliance 20 measures outer diameter increase during traveling,
Processor 13 passes through the first electric putter controller 15 after receiving signal and third electric putter controller 18 controls the first electric putter 5
And third electric putter 10 is when shrinking to avoid magnetizing coil 4 and 11 processes touched with joint of popping one's head in need certain
Between, since distance is too small between pipe diameter measuring appliance 20 and magnetizing coil 4 in the present invention, when the outer diameter and oil and gas pipeline of tube coupling
Outer diameter difference it is larger, it is mobile that the insufficient time makes the first electric putter 5 drive magnetizing coil 4, thus make magnetizing coil 4 with
Tube coupling collides, so as to cause normal detection is influenced, in order to overcome the above problem, on magnetizing coil 4 described in the present embodiment
Rangefinder 29 is arranged in front, and the rangefinder 29 and rangefinder signal receiver 30 are electrically connected, the rangefinder signal
Receiver 30 and processor 13 are electrically connected.Rangefinder 29 by rangefinder signal receiver 30 in real time to processor 13 transmitting with
The information of distance between tube coupling, processor 13 receives rangefinder 29 by rangefinder signal receiver 30 when close to tube coupling
Information, processor 13 control 9 retarded motion of power wheel by power wheel controller 17, give reason device 13 convenient for reserving the sufficient time
Pass through the first electric putter controller 15 after receiving signal and third electric putter controller 18 controls the first electric putter 5 and third
Electric putter 10 is shunk, and avoids magnetizing coil 4 from colliding with tube coupling, it is ensured that normal use of the present invention.
More specifically, due to when magnetizing coil 4 is contacted with oil and gas pipeline frictional force it is larger, cause the resistance of motion larger, by
It is limited in the electricity of power supply 14, to will affect detecting distance of the invention, in order to overcome the above problem, described in the present embodiment
Idler wheel 31 is set on magnetizing coil 4.The frictional force between magnetizing coil 4 and oil and gas pipeline can effectively be reduced by roller 31,
So that it is guaranteed that detecting distance of the invention.
Further, the power supply units such as battery, dry cell are generallyd use for the ease of mobile use due to power supply 14, but
It is that cannot carry out electric energy supplement using external environment in moving process at present, causes detection length shorter, it is above-mentioned in order to overcome
Problem, the outside of shell 1 described in the present embodiment are arranged solar power generation layer 32, the solar power generation layer by conducting wire with
Power supply 14 connects.Solar power generation layer 32 can convert solar energy into power storage in power supply 14 when sunny,
To be the power supply of power supply 14 using solar energy, increase moving distance of the invention, or even this can be made when sunlight is very sufficient
The continuous detection of invention, is easy to use.
Further, due to needing replacement power supply 14 in time when 14 electricity of power supply is low, it is ensured that detection is normally carried out, in order to
Overcome the above problem, power supply 14 described in the present embodiment and electrical quantity sensor 33 are electrically connected, the electrical quantity sensor 33 with
Processor 13 connects.The electricity of 33 real-time detection power supply 14 of electrical quantity sensor, and the information about power of power supply 14 is passed into processing
Device 13, cause when 14 low battery of power supply the present invention can not normal movement when, processor 13 pass through wireless signal transmitter 22
The accurate coordinate for this position that GPS module 28 positions is passed information into intelligent terminal 34, convenient for arranging personnel's replacement nearby
Power supply 14 is easy to use.
Further, intelligent terminal 34 described in the present embodiment is computer or mobile phone.
