Description
Technical field
The present invention relates to pipeline detection technical field, be a kind of transmitter, especially a kind of big electric current low frequency
Transmitter.
Background technology
Mainly using transmitter, signal clamp, receiver during pipeline detection, tested pipeline given by transmitter
Applying the signal code of a particular frequencies, general signal clamp or the tieline of passing through is to target pipeline
Apply current signal, receiver built-in sensitive coil, receive the magnetic field that the signal code on target pipeline produces
Signal, coil produces induced voltage, is divided by the induced voltage size of diverse location above detection target pipeline
Cloth is so that it is determined that the position of underground utilities and the degree of depth.Although present underground pipeline finder can be fine
Ground solves the detection problem of various underground utilities, but in place of prior art still also exists some shortcomings:
Such as investigation depth is smaller；Underground pipeline finder peak power output ripe in the market is general only
Having 10W, maximum output current is less than 1A, it is impossible to meet the requirement of big depth underground pipeline detection.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that one disclosure satisfy that big depth underground pipeline detection is wanted
The big electric current low frequency transmitter asked.
For reaching above-mentioned purpose, present invention employs following technical proposal: a kind of big electric current low frequency transmitter,
It is characterized in that, including internal with can the cavity of lithium battery of charge function, if cavity upper surface is provided with
Dry the delivery outlet can being connected with circuit, is provided with in the middle of cavity and can show the output display of electric current, electricity
Source switch, frequency selective switch and power regulating switch etc..
In above-mentioned a kind of big electric current low frequency transmitter, described cavity lateral surface is provided with guard box；Protect
Protecting box includes upper cover and lower cover.
In above-mentioned a kind of big electric current low frequency transmitter, described guard box is additionally provided with portable
Handle.
In above-mentioned a kind of big electric current low frequency transmitter, described delivery outlet is provided with three.
Compared with prior art, it is an advantage of the current invention that: by increasing the signal code size of target pipeline
Improve the Electromagnetic Survey of Underground Pipelines degree of depth and precision.

Guard box can be good at protecting the internal structure of cavity, it addition, be additionally provided with portable carrying on guard box
Hands 5.Guard box uses aluminium sheet material, improves heat-sinking capability.Cavity upper surface is provided with several can be with circuit
The delivery outlet 6 connected, in the technical program, described delivery outlet is provided with three, is provided with and can show in the middle of cavity
Show the display 7 of output size of current, and on and off switch, frequency selective switch and power regulating switch 8,
Circuit uses D class power amplification circuit module, improves power amplifier efficiency, and is beneficial to heat radiation, and circuit uses
Same signal generating circuit, to ensure the phase equalization of three delivery outlet signals；D class power amplification electricity
Road module uses three tunnel independent design, accurately to control the output size of current of each passage.Big electric current low frequency
Rate conjugation all has greatly than conventional conjugation on output, operating frequency and output electric current
Width improves.The output electric current of transmitter can bring up to about 2A, and output reaches about 200W, can
To solve the cable detection problem of the degree of depth 10 meters.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
