Marsh geophone

Abstract

The invention relates to a marsh geophone which solves the technical problems that a connecting wire core of the existing marsh geophone is difficult to weld; the production efficiency is low during batch production; quality defects of cold solder joint, welding slags of welding spots and the like occur frequently; the maintenance is difficult; the stretching resistance between an outgoing cable and a geophone core is weak; and the welding spot is easy to snap and short out because of the twisting force. The marsh geophone is provided with an outer protecting shell, a geophone core, a supporting shock insulator, a sealing guide sleeve, a compression plug, a pressure pad, an outgoing cable and a tail core, wherein the supporting shock insulator, which is a tensile supporting shock insulator, is provided with a tensile notch and a tensile connecting circuit board; and the pressure pad is a torsion-proof pressure pad. The marsh geophone can be widely used for marsh and shoal geophones.

Description

technical field [0001] The invention relates to a geophone, in particular to a swamp geophone. Background technique [0002] We know that in the field of oil exploration, swamp and shoal areas are often encountered during oil exploration, and the geophones used in these areas are swamp geophones. The existing swamp geophones are generally equipped with a geophone core, a fixed ring, a sealing rubber pad, a pressure pad, a cable clamp, an outer shell, a screw plug, and a lead-out cable. Solder to the positive and negative terminals of the detector core. [0003] This kind of swamp detector, because the internal fixing ring is an integral structure, it is difficult to operate when welding and connecting the core; when it is mass-produced, the production efficiency is low; there are often quality defects such as virtual welding and solder joint welding slag, and maintenance is difficult; The tensile force between the outgoing cable and the detector core is weak. When the scr...

Problems solved by technology

[0004] The purpose of the present invention is to solve the difficulty in operation when welding and connecting the wire cores of the existing swamp geophones, the low production efficiency during mass production, the frequent occurrence of quality defects such as virtual welding and welding slag in solder joints, the difficulty in maintenance, and the problems of leading out cables and the core of the geophone Weak tensile force between the solder joints, easy to open welding and short circuit due to torsion force on the solder joints, provide a simple operation for welding and connecting cores, high production efficiency in mass production, and no false soldering, solder joint welding slag, etc. Quality defects, strong tensile strength between the outgoing cable and the detector core, simple maintenance, solder joints will not be affected by torsion force to cause open welding, short circuit new swamp detector
