Abstract
The invention relates to an underwater cable cutting device which is used in combination with a geophysical exploration apparatus carrying a depth control unit. The depth control unit is provided with guiding planes which are protected by the cable cutting device mounted ahead of the depth control unit. The cutting device has a generally flat body having a curved forward portion and a pair of hook-shaped cutting portions on opposite rearwardly extending sides of the flat body for deflecting a cable from the depth control unit and severing the cable or mooring line with its cutting surface formed by the hooked-shaped cutting elements. The device is attached to an elongated housing and abuts a securing shank of the depth control unit, without requiring any modifications to be made to the depth control unit.
Claims10
An underwater cable cutting device for use with a geophysical exploration apparatus having an elongated housing carrying a depth control unit mounted thereon, said cutting device comprising:
- a substantially flat body means having a curved forward end portion;
- a pair of opposite side portions extending outwardly and rearwardly from said forward end portion;
- a bearing base rear portion;
- a pair of hook-like cutting portions disposed adjacent to rearmost parts of said opposite side portions, said cutting portions comprising a hook-shaped element curved towards said side portion and forming a cable receiving passageway therebewteen, said hook-shaped element further forming a generally circular cutting surface rearwardly from said cable receiving passageway;
- and
- a means for detachably securing said device to said elongated housing forward from said depth control unit.
An underwater cable cutting device for use with a geophysical exploration apparatus having housing carrying a depth control unit mounted thereon, said cutting device comprising:
- a substantially flat body having a curved forward end portion and having a transverse axis;
- a pair of opposite side portions, each extending outwardly and rearwardly from said forward end portion at an acute angle in relation to said transverse axis;
- a flat bearing rear base portion having a centrally located cutout groove;
- a pair of hook-like cutting portions disposed adjacent rearmost parts of said opposite side portions, each of said cutting portions being symmetrically disposed on opposite sides of the transverse axis of said flat body and comprising a hook-shaped element curved towards said side portion and forming a cable receiving passageway therebetween, said hook-shaped element further forming a generally circular cutting surface rearwardly from said cable receiving passageway;
- and
- wherein said body is being provided with an aperture forwardly from said cutout groove for receiving a securing screw therethrough to detachably secure the flat body to the elongated housing of the geophysical exploration apparatus.
