[0002] The transient electromagnetic method is a method that uses a wired power source or an ungrounded loop to emit a pulsed magnetic field underground, and uses an electromagnetic coil or a magnetic induction coil to observe the secondary induced eddy current field during the intermittent period of the pulsed magnetic field. Nowadays, the transient electromagnetic method is mainly used for geological exploration, and it has good effects in exploring underground ore bodies, oil, water bodies, and monitoring underground pollution, etc.

[0003] A transient electromagnetic device is an instrument that embodies the transient electromagnetic method. It mainly consists of a transient electromagnetic instrument, an output module, and a transmitting antenna. Among them, the structure and performance of the transmitting antenna directly affect the monitoring depth and accuracy. At present, the transmitting antenna has no fixed structure and is mainly temporarily built by operators on-site. Generally, a multi-strand coil is used for building, which has the disadvantages of shallow received signal depth and poor anti-external interference ability. Therefore, the present invention provides a transmitting device of a new type of transient electromagnetic device. Summary of the Invention

The fixed column 202 is hollow inside, there is a coil 16 inside the fixed column 202, there is a transient electromagnetic instrument interface 3 and a detachable electromagnetic coil interface 4 at the top of the fixed column 202. The transient electromagnetic instrument interface 3 is connected to the coil 16. There is a slot 6 on the outer side surface of the fixed column 202, and the bone support 201 is inserted into the slot 6 and connected to the fixed column 202. The bone support 201 is made of copper. The detachable electromagnetic coil 1 is divided into two types: a main electromagnetic coil 101 and a reflection electromagnetic coil 102. The main electromagnetic coil 101 is connected to the end of the bone support 201, and the reflection electromagnetic coil 102 is arranged in a net shape on the bone support 201. Both the main electromagnetic coil 101 and the reflection electromagnetic coil 102 can be removed from the bone support 201.

[0022] Preferably, the slot 6 on the outer side surface of the fixed column 202 runs through the fixed column 202 up and down. There are conduction copper sheets 7 on the two inner side surfaces of the slot 6, and the conduction copper sheets 7 are connected to the coil 16 inside the fixed column 202.

[0023] Preferably, the bone support 201 is composed of a connecting piece 8, a fixing screw 9, a support rod 10 and an anchor 11. The fixing screw 9 is located on the connecting piece 8, and both ends of the support rod 10 are connected to the connecting piece 8 and the anchor 11 through rotating shafts respectively.

[0024] Preferably, the support rod 10 is made of copper, and there is a fixed wire clip 13 on each support rod 10. The whole fixed wire clip 13 is made of copper, and the number of fixed wire clips 13 on each support rod 10 is not less than 4.

[0025] Preferably, the anchor 11 is made of copper, and there is a fixing buckle 12 for the main electromagnetic coil 101 on the anchor 11.

[0026] Preferably, the diameter of the main electromagnetic coil 101 is 30 mm ± 0.2 mm. There is a separately protruding lead interface 5 on the main electromagnetic coil 101. The lead interface 5 is matched with the detachable electromagnetic coil interface 4. There are metal lead buckles 15 at both the head and the tail of the main electromagnetic coil 101. The main electromagnetic coil 101 forms a closed loop through the metal lead buckles 15 at the head and the tail. The surface of the main electromagnetic coil 101 is wrapped with insulating rubber.

When the main electromagnetic coil 101 is not enough to surround the conduction skeleton 2, multiple main electromagnetic coils 101 can be connected end to end, and finally form a closed loop. When the installation of the main electromagnetic coil 101 is completed, connect the separately protruding lead interface 5 to the electromagnetic coil 16 interface of the top column of the fixed column 202. Then install the reflection electromagnetic coil 102. After the reflection electromagnetic coil is buckled on the fixed wire clip 13, it forms a quasi-reflection net structure with the bone strut 201. Thus, the present invention is installed. When in use, connect the transient electromagnetic instrument to the transient electromagnetic instrument interface 3 at the top of the fixed part to work.
