Description
Technical field
It the utility model is related to a kind of portable assembly transient electromagnetic coil device, more particularly to a kind of tunnel transient electromagnetic
Combined type transmitting, receiving coil.
Background technology
Transient electromagnetic detecting method is to produce electromagnetic excitation using transmitting coil, geologic body is produced secondary field, is encouraging
Source receives the secondary field of geologic body generation using receiving coil after closing, by analyzing secondary field Decay Law back analysis geologic body
Apparent resistivity, achievees the purpose that to detect low-resistance geologic body.Lane (tunnel) road total space transient electromagnetic method has convenient test, work
Efficient, high resolution and it is widely used in advance geologic prediction the advantages of be quick on the draw to post non of low resistance body (water-filling, folder mud),
And one of an important factor for transient electromagnetic is launched, receiving coil performance is decision test data quality.
The design wide variety of transient coil and stent at present, usually forms circular or square outer edges using different materials
Frame, then by artificial circle into coil be fixed on frame, due to circle into coil be integral type, and there is larger size,
Its full extension is difficult to ensure that when in use, and actual size and theoretical value have certain deviation, and large scale coil packaging and fortune
It is defeated also extremely inconvenient.Since the cross dimensions in different lanes (tunnel) road, detection accuracy and detection range are different, need to according to its it is specific will
Definite coil turn and the area of plane are asked, same coil can not meet the detection requirement to all engineerings, and field-winding coil needs
When it is longer, coil utilization rate is low.In addition, the transmitting of the common coincide-loop in lane (tunnel) road and receiving coil often mutually twine
Strong around, both mutual inductance signals, test data early time data resolution ratio is very poor, and it is accurate to influence near field country rock unfavorable geology prediction
Property.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of portable assembly wink
Become electromagnetic spool device, to meet the quick assembling of low mutual inductance, Different Plane size and number of turn transient electromagnetic coil device coil
With the purpose of test.
Technical solution：To achieve the above object, the technical solution adopted in the utility model is：
A kind of portable assembly transient electromagnetic coil device, including bar, connector and output line, bar pass through connector
It is end to end to be assembled into closure wire frame；Parallel arrangement has some cores in the bar, the core include transmitting core and/
Or receive core；The connector includes AN connector and jumper coupler, and jumper coupler is provided with delivery outlet, output line
Picked out by the delivery outlet of jumper coupler.
In this case, jumper coupler is compared with AN connector, in addition to bar wiring connector is provided with delivery outlet, its both ends
The connection mode of (side a and b) is according to also likely to be present difference：AN connector only by the binding post of both ends same position into
Row connection；And in order to which all cores are connected into single line (transmitting receives) or both threads (transmitting+reception), wire jumper connection
Device needs A, B end both ends jumping a connection, such as the mode of connection of jumper coupler in Examples hereinafter.
In this case, transient electromagnetic coil includes two kinds of transmitting coil and receiving coil, can separate and design, based on this case,
Only launch core i.e. in bar and only receive the situation of core；But conventional method is to fold transmitting coil and receiving coil
It is added together, based on this case, i.e., there is transmitting core in bar at the same time and receive core.Core and connect for transmitting is provided simultaneously with
The situation of take-up core, all cores in the cable leather sheath of bar are divided into two parts by us, and a part, which is used as, launches core, and one
Part is as reception core, and the accounting of two kinds of cores can be distributed according to circumstances.As shown in figure 3, F cores are used for being connected into
Transmitting coil, S cores are used for being connected into reception core, finally pick out four connectors (hair from wire jumper receiver (51 in Fig. 5)
Ray circle and each two the end of a thread of receiving coil).

One shares 100 circle cores, and transmitting core (or transmitting coil) has n circles, and receiving core (or receiving coil) then has 100-n circles,
The number of turn can also be reduced by subtracting circle connector on the basis of this, can be at least respectively 1 circle.
Preferably, connected between the bar and connector by pin and box sub, to improve the versatility of all parts.
Preferably, one or more adjacent core parallel connection is subtracted circle by each binding post on the connector to be formed, i.e.,
On the basis of conventional each binding post connects a core, several adjacent cores are together in parallel and are connected to one by we
On binding post.Due to having been completed that connector both ends correspond to the connection of binding post in AN connector and jumper coupler, because
This by the way of each binding post a plurality of core in parallel, undoubtedly adds wire core diameter, reduces relative to conventional connection mode
The number of turn of same line cored wire rod composition coil.For example, it is originally 100 circle 2mm2Core, if by 2 adjacent parallel connections, this
Two, sample is simultaneously done one (although both threads core is really separated, effect is the same), and section is changed into 2 × 2mm2, circle
Number is changed into original 1/2, i.e. 50 circles.We can there will be connector in parallel to be known as subtracting circle connector, is specifically divided into and subtracts circle
AN connector and subtract circle wire jumper and connect machine.
Preferably, the bar is in series by more than one standard bar.The design causes whole transient electromagnetic coil
The component of smaller can be split into, is also convenient for being assembled into the transient electromagnetic coil of bigger.
Preferably, the pin and box sub at the standard bar both ends is adapted with the pin and box sub on connector, i.e., single mark
Directrix rod can be directly connected with connector.
Preferably, the core parallel arrangement in the bar, the transmitting coil that is formed by connecting by transmitting core and by receiving
The receiving coil that core is formed by connecting, the harness after connector do not intersect.
Preferably, the bar is linear pattern or arc line type, and joint connector can be assembled into square, rectangle, circle
Shape, ellipse etc. close wire frame, that is, form transient electromagnetic coil of different shapes.
Preferably, the length of the bar is 0.2~10m, and the quantity of core is 4~200 in bar, core it is a diameter of
0.1~10mm2。
Preferably, the lapping of the lapping of core, the lapping of bar and connector is non-conductive material,
Such as PVC, PE, EVA or glass fibre.
Beneficial effect：Portable assembly transient electromagnetic coil device provided by the utility model, relative to the prior art, tool
There is following advantage：1st, transmitting and receiving coil are made of bar, AN connector, jumper coupler and output line, large scale line
Circle can also be composed in series by more bars, convenient to carry and carry over long distances, and Assembling is convenient, it is only necessary to which 2 people can complete
The competent work of 3~4 talent of normal coil；2nd, using non-conductive material by transmitting coil fixation parallel with receiving coil core
In bar, the artificial winding coil core mutually strong mutual inductance effect caused by is reduced, improves near field country rock detection validity
And precision；3rd, AN connector and jumper coupler can be by adjacent more core parallel connections, it is only necessary to which replacing connector can be assembled into
Few circle, low magnetic flux amount, small turn-off time coil, substantially increase the utilization rate of coil, using same bar realize shallow-layer and
