Time-domain aeroelectromagnetic method receiving coil attitude change suppression device and manufacturing method thereof

Abstract

The invention relates to a time-domain aeroelectromagnetic method receiving coil attitude change suppression device and a manufacturing method thereof. The time-domain aeroelectromagnetic method receiving coil attitude change suppression device is characterized in that connection points are uniformly arranged in a fixed bracket in circumferential manner; the center point of the circular inner surface of the top layer is provided with a receiving coil bearing connection point; a receiving coil is wound in the axial direction of the receiving coil in a differential structure; fixed connection points are uniformly arranged on the outer surface; the center point of the circular outer surface of the top layer is provided with a receiving coil bearing connection point; through flexible or rigidbinding ropes, the connection points are connected in the radial direction of the receiving coil, and through the flexible binding rope, in the axial direction of the receiving coil, the receiving coil bearing points are connected, thus guaranteeing attitude balance of the receiving coil; and the binding rope enables the receiving coil not to generate moment in the pitching and rolling directions,thus suppressing generation of motion fundamentally; and by means of damping fluid, vibration isolation effect is achieved, and at the same time, the mobile resistance of the receiving coil is increased, thus further limiting spatial displacement of the receiving coil, and improving the primary field compensation effect. The time-domain aeroelectromagnetic method receiving coil attitude change suppression device overcomes limitations of application.

Description

Technical field: [0001] The invention relates to a device for suppressing attitude change of a receiving coil of a helicopter time-domain airborne electromagnetic method, in particular to a pod-type helicopter time-domain electromagnetic detection receiving device. Background technique: [0002] The pod-type helicopter time-domain electromagnetic detection device uses the helicopter as a carrier, and mounts the transmitting coil, compensating coil and receiving coil through hanging ropes. The transmitting coil emits a fixed-frequency bipolar periodic large current to excite the eddy current effect of the underground medium to generate a changing magnetic field signal. The receiving coil receives the changing magnetic field signal and collects it in real time through the receiving system, and then processes and interprets the collected data. , to complete the geological survey. When the bipolar periodic large current passes through the transmitting coil, it will flow in the ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the above-mentioned existing receiving coil introduces motion noise due to the change of pitch angle and roll angle caused by vibration during flight, and provides a restraint device for changing the attitude of the receiving coil to limit the spatial displacement of the receiving coil so that it It is suitable for hard or soft supports in the center mode or eccentric mode, and weakens the motion noise by reducing the moment in the pitch and roll directions. It is suitable for the attitude change suppression device of the receiving coil of the helicopter time-domain airborne electromagnetic method;
