Abstract

The invention provides a whole sealing double check detector which solves the technical problems of poor sealing performance caused by unsteady quality and burn-in of an O-shaped sealing ring and reduced anti-jamming capability and short lifetime both caused by silicone oil leakage of the existing double check detector. The whole sealing double check detector is provided with an outer shell; the outer shell is internally provided with a main rotating hull; the main rotating hull is provided with a detector core; one side of the outer shell is provided with an outgoing cable and a sealing plug, and the other side of the outer shell is provided with a hydrophone probe; the outer shell and the hydrophone probe are externally provided with an outer protecting shell; and the outer protecting shell is connected with the sealing plug. The whole sealing double check detector can be widely used in the area of the detector.

Description

technical field [0001] The invention relates to a geophone, in particular to an integrally sealed double geophone. Background technique [0002] We know that double geophones are often used in oil exploration in shallow seas, shoals and deep seas. During construction, the dual geophones are placed on the seabed or the bottom of the lake. Due to different construction environments, sometimes very deep waters are encountered. Therefore, the waterproof requirements for the double detector geophone are very high. If the waterproof performance is not good, the double detector geophone will leak electricity, and serious quality problems will occur, resulting in the inability to collect on-site data; The damping silicone oil filled inside the double detector leaked, which caused its performance to decline and eventually became unusable. The existing dual geophones are provided with a main rotating hull, on which a geophone core is arranged, two ends of the main rotating hull are r...
