Embodiment Construction

[0008] figure 1 It is a schematic diagram of the structure of the present invention. After winding the induction coil with a multi-strand wire on the plastic shell with a through hole in the middle of the cylinder, place it horizontally and use a multimeter to measure and record its various parameters, which are inductance, D, parasitic capacitance, and Q value respectively. , AC resistance and DC resistance. The induction coil is fixed by using a modified acrylate adhesive with fast curing speed and high bonding strength, which is suitable for bonding various industrial materials. Because if the glue is applied to the induction coil, although the relative position between the wires in the coil can be kept unchanged, and its parameters are stable, this will reduce the horizontal and vertical line spacing of the induction coil too much. As a result, the Q value decreases, the inductance and AC resistance increase, and the ideal state after the induction coil is fixed is that i...

Abstract

The invention discloses a fixing method of an induction coil. A plurality of strands of wires are sequentially wound on a cylindrical plastic shell to obtain an induction coil with certain parameters.The induction coil is fixed by using a modified acrylate adhesive according to certain steps. As a result, when the induction coil is in a horizontal placement state and the outside environment of the induction coil is shaken, the appearance and various parameters of the induction coil are not changed at all. The induction coil can be used for manufacturing the reader-writer of an underground pipeline electronic detector. After being fixed, the induction coil can improve the stability and the detection efficiency of the detector.

Description

technical field [0001] The invention relates to the field of wire rods, and more specifically relates to a fixing method of an induction coil. Background technique [0002] Nowadays, due to the rapid development of science and technology, social economy and urban construction, the society's demand for mining and utilization of underground resources is increasing day by day. However, in many cases, the underground situation is complex and unknown, especially in recent decades, the pipelines laid underground are intricate, and there is no accurate drawing of the overall position distribution. It is possible to touch underground pipelines during development and utilization, which may cause accidents and bring losses in all aspects. Among them, the gas pipeline is one of the most widely distributed and numerous pipelines in urban underground pipelines. If the gas pipeline is touched, it will cause safety problems such as leakage, rupture, explosion, and road collapse of the gas...
