  • Remote underwater excavator and sampler
    Patent number: 4932144
    Abstract: An underwater excavator in which when energized by a supply of hydraulic oil or other means a propeller is set in motion with water being drawn through a water intake into a cylindrical tube and expelled at the water outlet to create a flow of water of sufficient volume and velocity to blow away seabed materials. Thrust and torque are counteracted by the suction force developed at the water intake. Optional filter nets or sieves may be fixed to a foot of the machine to capture samples of the material washed out of the seabed.
