DEVICE OF MULTI-SECTION MULTICHANNEL EXTENDED TOWED SEISMIC RECEIVE SYSTEM Russian patent published in 2023 - IPC G01V1/38 B63B21/60 

FIELD: seismic exploration.

SUBSTANCE: invention relates to seismic exploration, namely, to technical means for receiving seismic acoustic signals and can be used in multi-section multi-channel cable-type extended seismic receiving systems that require mechanical and electrical integrity to be maintained during operation of the system during towing. A device for a multi-section multi-channel extended towed seismic receiver system is proposed, containing series-connected multi-channel cable-type seismic receiver sections, each of which contains seismic receivers according to the number of channels in the section, hose connectors, wired communication lines connected to hermetic multi-contact pin-type connectors, ring-type power cables, holders power cables consisting of two disk rollers installed with the help of a vertical axis in the holder. Moreover, the hose includes a device for compensating the tightening of wire communication lines inside the hose towards towing, consisting of two cylindrical support bushings installed vertically on both holders of power cables, with wire communication lines fixed to them with a thread bandage.

EFFECT: preservation of the electrical and mechanical integrity of the intra-hose communication lines of the multi-channel sectional extended towed receiving device due to the reverse tightening of the wire lines when the towing force is removed.
