Acoustic wave receiver for underwater seismic prospecting

Claim 1

An acoustic wave receiver for underwater seismic prospecting comprising a plurality of tubular sections filled with liquid and containing coupled pressure transducers, electric conductors interconnecting the transducers, a multiconductor electric cable having a tight sleeve adjacent each end thereof and an electrical connector arranged at each end, towing cables and coupling means for interconnecting the tubular sections, said coupling means including couplers secured to the ends of the tubular sections, each coupler having a wall with an internal protrusion forming a bearing and first and second recesses separated by said bearing, means for anchoring the ends of the towing cables, said anchoring means being secured within the coupler at the region of the first recess, means for connecting the electrical connector in a predetermined angular position substantially at the end portion of the coupler containing the second recess and removable means for fastening the sleeve of the multiconductor cable to said bearing, said coupling means also including a coupling member for interconnection of the couplers, said coupling member having an internal section substantially equal to the external section of the end of the coupler containing the second recess and having additional means for the angular positioning and fastening of each coupler, and sealing means associated with the external wall of the sleeves of the multiconductor cable and with the end of the coupler contained in the coupling member for insulating said second recess of the coupler from the internal liquid of the tubular sections and from the surrounding water.
