| description | According to the underwater distance measurement method based on double-water-flow intersection, a double-jet-flow intersection fixed-point measurement technology is provided, so that interference of environmental factors on optical equipment, acoustic equipment and the like is overcome, and efficient, accurate and continuous distance measurement is achieved. Belongs to the field of ocean engineering and underwater exploration, in particular to a double-water-flow jet device which comprises a base, two groups of nozzles are arranged at two horizontal ends of the base, the two groups of nozzles have the same vertical mounting height, and each group of nozzles can horizontally and vertically rotate in a reciprocating manner around a fixing shaft in a horizontal plane on the base; during measurement, the two groups of nozzles respectively eject a group of water flow with the same water pressure and direction, the initial ejection pressure of the water flow is the pressure pumped out by the water pump, an interse |
