Solenoid coil applied to time domain aviation detection of helicopter

Abstract

The embodiment of the invention provides a solenoid coil applied to time domain aviation detection of a helicopter. The solenoid coil comprises metal conductive straight pipes, metal conductive bending pipes and sleeves, wherein the metal conductive straight pipes and the metal conductive bending pipes are sequentially connected at intervals by the sleeves to form an enclosed coil, the metal conductive straight pipe and the metal conductive bending pipe respectively comprises an inner embedment core and an outer sleeve, the inner embedment core is embedded into the outer sleeve and is a carbonfiber composite material, and the outer sleeve is an aluminum alloy material. The solenoid coil applied to time domain aviation detection of the helicopter, provided by the embodiment of the invention uses the metal conductive straight pipe made of the carbon fiber composite material inner embedment core and the metal conductive bending pipe made of the aluminum alloy material outer pipe, and themetal conductive straight pipes and the metal conductive bending pipes are fixedly connected by the sleeves to form the enclosed coil; and with the adoption of the carbon fiber composite material andthe aluminum alloy material, the requirements that the emission magnetic torque of an electromagnetic emission coil is constantly increased while the weight of the solenoid coil is not increased aremet on the premise that an emission current of the solenoid coil is enabled not to be changed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of airborne electromagnetic exploration, and in particular to an electromagnetic coil for helicopter time-domain aerial exploration applications. Background technique [0002] At present, with the rapid development of my country's economy, people's demand for mineral resources continues to increase. The exploration of mineral resources has been basically completed in areas with relatively superior terrain conditions in China. However, although the central and western regions, which account for more than 65% of my country's land area, are rich in mineral resources, due to their extremely harsh terrain conditions, it is impossible for staff to carry out exploration work on the ground, resulting in the rich mineral resources contained in it. be exploited effectively. In order to solve this problem, people's research on mineral resource exploration methods gradually turned to airborne elec...

AI Technical Summary

Problems solved by technology

[0004] At present, the electromagnetic coils used for aeronautical electromagnetic exploration at home and abroad are all made of copper, which leads to the coil itself being soft and poor in hardness. It must be equipped with a bracket to support the coil itself.

Because the copper itself has the characteristics of high density and heavy mass, coupled with the weight of the bracket, the weight of the entire electromagnetic launch device is greatly increased. The heavy electromagnetic coil makes the load capacity of the flight platform close to the rated value, reducing the The efficiency of the entire electromagnetic exploration system cannot meet the requirements of increasing the emission magnetic moment of the airborne electromagnetic transmission coil with the continuous increase of the exploration depth of mineral resources
