The utility model provides an underwater detection equipment separator, the device is by the separator, detection equipment carrier two parts constitutes, the separator includes the disconnecting lever, disconnecting lever transmission sleeve, the sleeve is retrieved to the disconnecting lever, the separator base, the separator latch hook, separator latch hook hook is tied, carrier fixed steel wire rope, parts such as electric cap, the detection equipment carrier is by the plane platform, the detection equipment support frame, detection equipment support frame locator, the detection equipment layer board, the separator fixed plate, the wire rope lantern ring, remove constitutions such as pulley. The device is after detecting device forms wholly with the detection equipment carrier, the small blasting power of launching the sleeve electric cap through the disconnecting lever jets out the disconnecting lever that gets into in the disconnecting lever recovery sleeve with the disconnecting lever from disconnecting lever transmission sleeve and retrieves the room, solid latch hook was not owing to there has been the retardation of disconnecting lever to come off rapidly this time, the wire rope who hangs on solid latch hook also drops rapidly, wire rope no longer produces the fastening effect to detecting device and detection equipment carrier platform, thereby the separation of underwater detection equipment has been realized.
