Description
Technical field
The utility model relates to the multipurpose sending-receiving integration coil design techniques fields of electromagnetic prospecting, specifically
It says, is related to a kind of adjustable assembled electromagnetism of effective area and disappears coupling coil brace.
Background technique
Electromagnetic prospecting has been widely used for mineral exploration, engineer geological prospecting, groundwater resources, underground utilities at present
It is produced using electromagnetism transmitter with fields such as environmental geology explorations wherein there are commonly frequency domain electromagnetic methods and time domain electromagnetic method
Raw excitation primary field, the secondary field of geologic body induction is acquired by receiver, detects structure of geological body by analysis secondary field.
The shortcomings of the prior art is:
1, the size of coil device and the number of turns of coil cannot be adjusted, and larger-size coil device is unfavorable for transporting, and
It increases in task difficulty precipitous, in narrow environment；Spacious construction site, fixed structure coil cannot amplify single turn and send line
Area is enclosed, transmit coil effective area cannot be improved, is unfavorable for deep prospecting.
2, the electrodynamic capacity of the turn-off time and transmit coil that under normal circumstances, send electric current are proportional, and the latter's direct ratio
In square of transmit coil the number of turns.The number of turns by reducing transmit coil can significantly shorten the turn-off time for sending electric current, from
And richer high-frequency excitation signal is generated, be conducive to lifting means in the sensitivity of shallow-layer field of detecting.For same diameter
Transmit coil, the transmission effective area of equipment can be increased by increasing the number of turns, this be conducive to lifting means to deep layer detect
The detectability of target.The transmit coil parameter of existing coil device is unadjustable, it is difficult to take into account and bury in different depth
Hide the Effect on Detecting of object.
Utility model content
In view of the foregoing drawbacks, disappear coupling coil branch the utility model proposes a kind of adjustable assembled electromagnetism of effective area
Frame is easy to on-site assembly, dismantling, is readily transported, cable can remove at any time and pack up and install, and configure the firing cable of different length
And cross brace, the adjustable range of transmit coil effective area can be expanded, improve the adaptability to superficial part, deep detection.
In order to achieve the above objectives, the specific technical solution that the utility model uses is as follows:
A kind of adjustable assembled electromagnetism of effective area disappears coupling coil brace, is provided with central supported, the central supported is living
Dynamic to be equipped at least two coil strut, the coil strut is fixed in central supported through locking mechanism, and with central supported
Center is the center of circle, outside ray divergence, and the free end that the coil strut exhales is n, n >=3；
Change with the length of the coil strut, distance change of the free end apart from the center of circle, n free end surrounds
The area S and perimeter Z of coil support follow variation；
Around the flexible cable for being l equipped with length in the coil support, the l is the integral multiple of Z.
The effective area of coil refers to the single turn area of coil and the product of the number of turns, by above-mentioned design, on the one hand, hair
Sending coil cable can be installed on demand, and when needing stronger transmitting signal, the flexible cable of more the number of turns is coiled in coil support,
Otherwise the number of turns of transmit coil cable is reduced, on the other hand, the single turn area of coil is formed by area by n free end and determines
Fixed, if adjustment free end is with central supported central point at a distance from, area naturally-occurring changes, then the single turn area of coil is therewith
Change.
The firing cable for configuring different length can expand the adjustable range of transmit coil effective area, adjust coil tight beam
Folder forms the conversion of different support length, and bracket tune is short and when increasing transmit coil cable the number of turns, can promote transmit coil to narrow
The adaptability of narrow working space, and when bracket elongation and reduction transmit coil cable the number of turns, transmit coil self-induction can be reduced, it is right

The above design structure can install coil support in the case where through-hole is only arranged, at this point, enabling one or a few line therein
The adjusting rod that strut is length adjustable is enclosed, the cradling piece that at least one passes through the through-hole is length adjustment bar,
That is: the both ends of coil strut described at least one are free end, on the free end and harness guiding device medial surface central point
Joint screw thread assembly, the lateral surface of the harness guiding device are provided with cable trough.
Above-mentioned design coil strut is also configured as removable, more convenient transport with harness guiding device, and has two kinds of adjusting sides
Formula, one are to fix coil strut, and rotation harness guiding device forms spacing and adjusts, second, fixing harness guiding device, rotates
Coil strut obtains same regulating effect, but harness guiding device is often in stationary state when having installed around cable, turns at this time
Moving winding strut, more fast.
Coil strut by replacing different length significantly adjusts the transmitting coil single turn area of coil support
It is whole, by adjusting the single turn area of harness guiding device and the distance fine regulation transmitting coil of coil strut.
Be screwed on by screw thread realize between the two away from elongation and shortening, since the fine difference of effective area all may
Last Effect on Detecting is had an impact, therefore the mode of rotation screw thread is selected to adjust, every rotation screw thread is once to single turn area
Influence it is smaller, i.e., the minimal adjustment degree adjusted each time is smaller, and user can more precisely debug out optimal effectiveness.
On this basis, the threaded line at coil strut both ends is contrary.
At this point, can shorten simultaneously or extend the distance at both ends by rotation single line circle strut, more efficient tune is formed
Section.
The further scheme of first aspect, the bulk connector are also provided with the blind holes that a2 dissipates outward, described in a2 root
The connecting pin of coil strut is plugged in the a2 blind holes and transition fit respectively, and the free end of the coil strut is respectively set
