Carrying structure for aviation transient electromagnetic coil

Abstract

The invention discloses a carrying structure for an aviation transient electromagnetic coil. The carrying structure comprises a polygonal frame and coil supporting cushions, wherein the polygonal frame is formed by sequentially connecting a plurality of air columns and a plurality of bent connectors, and the coil supporting cushions are arranged on the air columns. The bent connectors are of double-way structures with angles, the two ends of the bent connectors are nested with the ends of the air columns, and the angles of the bent connectors are identical to the angle of a polygon. Hanging connectors are arranged at the turning position of the bent connector. Line slots for laying electromagnetic cables are formed in the coil supporting cushions. Heat insulation layers are arranged in line slots. Regarding the characteristics that the aviation transient electromagnetic coil is huge in size, the requirement of the carrying structure for specific stiffness is high, and the requirement for materials are limited, the carrying structure for the aviation transient electromagnetic coil, wherein the carrying structure is different from the foreign technology and has the advantages of being large in size, good in rigidity, small in mass, convenient to use and maintain and the like.

Description

technical field [0001] The invention relates to the field of aeronautical geophysical prospecting, in particular to an aeronautical transient electromagnetic coil carrying structure. Background technique [0002] Aeronautical transient electromagnetic geophysical prospecting method is a fast and economical geological survey method. This method uses the principle of electromagnetic induction to establish a pulsed magnetic field of the ground and minerals by electrifying the electromagnetic transmitting coil on the aircraft, and then receives the ground and mineral induction. The secondary magnetic field is used to detect geological and mineral information. In order to ensure that the transmitting coil in the air can generate a large enough magnetic field, it is necessary to make the area of ​​the transmitting coil large enough. [0003] Due to the large area of ​​the transmitting coil, it is necessary to have a support structure that is compatible with the coil and is not ea...

AI Technical Summary

Problems solved by technology

[0003] Due to the large area of ​​the transmitting coil, it is necessary to have a support structure that is compatible with the coil and is not easily deformed; at the same time, the coil and its support structure are carried on the aircraft, and the weight of the support structure must be as light as possible; Therefore, the supporting structure cannot use materials with high dielectric properties such as metals

At present, there are coil carrying devices made of glass fiber or wood structure in foreign countries, but the construction is difficult and the cost is high, and there is no relevant research in China
