Coil vibration reduction pod device capable of being rapidly disassembled and assembled for aviation large-size magnetic sensor

Abstract

The invention relates to a coil vibration reduction pod device capable of being rapidly disassembled and assembled for an aviation large-size magnetic sensor. A vibration reduction pod comprises multiple straight pipes, multiple bent pipes, a rope positioning protection ring and screws, wherein the straight pipes and the bent pipes are alternately connected in series to form an overall polygonal pod structure; the rope positioning protection ring is arranged on the bent pipes, is of an annular structure, is provided with an annular groove, is used for fixing a hanging cable and is made of a nylon material; the vibration reduction pod is of a sectional type detachable sleeve pipe structure, two ends of each straight pipe and two ends of each bent pipe are provided with sleeving structures, and the caliber of the tail end of the left side of the straight pipe is larger than that of the right side of the bent pipe, so that the tail end of the right side of the bent pipe can be embedded into the tail end of the left side of the bent pipe, the caliber of the left side of the bent pipe is larger than that of the tail end of the right side of the straight pipe, so that the tail end of the right side of the straight pipe can be embedded into the tail end of the left side of the bent pipe, and rivet holes and built-in thread fastening aluminum strips are reserved at the tail ends of the left side and the right side of the straight pipe and the tail ends of the left side and the right side of the bent pipe; and a plurality of straight pipes and bent pipes are assembled into the complete polygonal magnetic sensor coil pod device.

Description

technical field [0001] The invention relates to the field of geophysical airborne electromagnetic prospecting, and belongs to a quickly disassembled and assembled aviation large-size magnetic sensor coil vibration-damping pod device, which is mainly used to reduce structural vibration noise of an aviation pod-type large-size electromagnetic receiving system during flight The influence on the magnetic sensor coil can be applied to the aerial pod type electromagnetic detection equipment system. Background technique [0002] Airborne electromagnetic prospecting system is a kind of airborne geophysical prospecting equipment based on the electrical difference of underground medium or target body to realize geological structure or resource detection. The system has the characteristics of low cost, high efficiency, and good trafficability. It can be used for resource detection target selection and resource reserve rapid evaluation in areas covered by surface vegetation, lakes, swam...

AI Technical Summary

Problems solved by technology

[0007](1) The pod structure of the existing aeronautical electromagnetic receiving system cannot support large-sized magnetic sensor receiving coils, and the detection sensitivity of small-sized magnetic sensor receiving coils is low. It will affect the overall performance of the airborne electromagnetic detection system;

[0008] (2) The hard connection between the receiving coil and the supporting and fixing device of the pod, so that the vibration generated during the flight is directly transmitted to the receiving coil through the hard connecting device, resulting in relatively Large motion noise does not meet the requirements of airborne electromagnetic methods for noise suppression; or only by filling the pod with soft objects such as sponges to fix the receiving coil, it can play a role of fixed support and vibration reduction to a certain extent, but the reduction The vibration effect is very limited, which does not meet the requirements of the airborne electromagnetic method on the vibration and noise of the system

[0009](3) The pod structure of the existing aeronautical electromagnetic receiving system is mostly half-cover type, and it is necessary to use more half-covers and rivets to connect the upper and lower polygonal half- The cover structure is fixed, which is inconvenient to install and cannot be quickly disassembled, which affects the efficiency of field operations and is not easy to carry and transport
