Ball conical suspension device for time-domain aero-electromagnetic method transmitting coil

Abstract

The invention discloses a ball conical suspension device for a time-domain aero-electromagnetic method transmitting coil. The ball conical suspension device comprises a support frame and hoisting ropes, wherein the support frame is formed by connecting a plurality of circular tubes in a cross manner; a central cross-shaped connector is arranged at the intersection of the circular tubes; a plurality of hoisting ropes are provided; one end of each hoisting rope is connected with the plurality of circular tubes of the support frame respectively; the other ends of the hoisting ropes are gathered above the center of the support frame, and fixedly and integrally connected at a gathering point; the plurality of hoisting ropes are tensioned respectively; the support frame at the bottom is suspended and hung in balance; and fixed hanging buckles are arranged at the joints between the support frame and the plurality of circular tubes respectively. Through adoption of the ball conical suspensiondevice, the suspension of a transmitting coil cable is realized, the weight of the whole structure is mainly carried by the hoisting ropes, the stress on a support rod is reduced, and the integral structure is more stable. Meanwhile, no bolt structure is used, each component is made of glass fiber or a high molecule rope, and no conductive component is used in the structure, so that interference with electromagnetic emission is avoided.

Description

technical field [0001] The invention relates to a transmitting coil suspension frame, in particular to a spherical cone suspension device used for a time-domain airborne electromagnetic method transmitting coil. Background technique [0002] The time-domain airborne electromagnetic method (ATEM) detection system is a kind of airborne geophysical prospecting. As a fast and economical high-tech exploration method, airborne geophysical prospecting is widely used in western developed countries, mainly for metal mineral resource investigation, regional resource exploration and geological mapping. Flight operations can greatly expand the detection speed and application range, and greatly improve the efficiency of resource exploration. [0003] The time-domain aeronautical electromagnetic detection system consists of on-board equipment such as on-board data acquisition and recording computers, and external transmitter coils and receiver coils. The transmitting device emits a time...

Problems solved by technology

[0004] The current time-domain airborne electromagnetic method measurement system has a variety of structural forms for the transmitting coil support frame, and the connection of the support rods is mostly bolted. On the one hand, the complexity of the structure is increased, the installation is cumbersome, and the structural stability is difficult to control. If there is a metal component in the connector, electromagnetic noise may be induced and affect the performance of the device
