Embodiment 1
[0041] For the time-domain electromagnetic detection system of the soft support helicopter in the center mode, the transmitting coil 3 and the compensation coil 4 are concentric circles in the same plane. Based on their size, the size of the receiving coil 52 is calculated by using the principle of primary field compensation to determine the fixed support 51 and the size of the fixed bracket base 54.
[0042] After determining the size, it is made of completely non-magnetic material.
[0043] Make evenly distributed connection points 521, 522, 523, 524, 525, 526 at the center of the axis of the outer circumferential surface of the receiving coil, and make a receiving coil gravity bearing point 527 at the center of the top circular area.
[0044] The receiving coil bearing point 517 is arranged at the center of the circular area on the top layer of the inner surface of the fixing bracket 51, corresponding to the receiving coil gravity bearing point 527, and the two-point connection di...
Embodiment 2
[0053] For eccentric hard or soft stent helicopter time-domain electromagnetic detection systems, the transmitting coil 3 and the compensation coil 4 are eccentric circular structures in the same plane. Based on their structure and size, the size of the receiving coil 52 is calculated using the principle of primary field compensation. , Thereby determining the size of the fixed bracket 51 and the fixed bracket base 54.
[0054] After determining the size, it is made of completely non-magnetic material.
[0055] Make evenly distributed connection points 521, 522, 523, 524, 525, 526 at the center of the axis of the outer circumferential surface of the receiving coil, and make a receiving coil gravity bearing point 527 at the center of the top circular area.
[0056] The receiving coil bearing point 517 is arranged at the center of the circular area on the top layer of the inner surface of the fixing bracket 51, corresponding to the receiving coil gravity bearing point 527, and the two-...
