Abstract:
A submerged maritime pump comprising:a) a plurality of supports; b) a hollow tube pump body having opposite lateral sides slidably mounted on the plurality of supports, the hollow tube pump body having front and rear ends; c) a floating block mounted on the hollow tube pump body so as to position the hollow tube pump body at a predetermined level below a water surface; d) a hopper mounted on the front end of the hollow tube pump body including a plurality of surfaces inclined outwardly from the pump body so as to direct water into the tube pump body; e) an outlet pipe mounted to the rear end of the tube pump body and having therein an anti-countercurrent valve, a cross-section of the outlet pipe being smaller than a cross-section of the hollow tube body; f) an intake on the rear end of the tube pump body, the intake including an intake gate pivotally connected to the tube pump body so as to pivot inwardly into the tube pump body to open the intake and a stopper to locate the intake gate in a closed position; g) a plurality of guiding sticks located within the tube pump body; and, h) a piston slidably movable on the guiding sticks and located within the tube pump body so as to be movable between the front and rear ends of the tube pump body, the piston having a cross-sectional configuration the same as the tube pump body, whereby movement of the piston from the front end of the tube pump body towards the rear end urges water in the tube pump body through the outlet pipe.
