Embodiment 1

[0069] The propulsion scheme on both sides of the bow of the leading water propelled ship of the present invention will be further described in Embodiment 1 in conjunction with the accompanying drawings.

[0070] As shown in Fig. 1 and Fig. 2, a double-slope plowshare type pipe nose body 5 is set under the water level line in the front projection of the bow 2, and the nose pipes arranged on the slopes on both sides are used as the water inlet 21, and the bottom axis It is the extension of the longitudinal axis of the bottom of the ship. The two sides of the bottom are tilted into a double-wing V shape. The two sides and the upper part are connected with the bow 2, and the adjustable horizontal grid type sewage is set outside the water inlet 21 on both sides. Grid 41. On the upper part of the round bilge 8 of the front shoulder 3 on both sides of the hull 1, the water outlets 22 on both sides of the rearward bow of the symmetrical position and the half of the symmetrical mouth ...

Embodiment 2

[0079] Below in conjunction with the accompanying drawings, the scheme of setting the stern propulsion and flow layer on the leading water propulsion ship of the present invention will be further described in Embodiment 2.

[0080] As shown in Figures 11 and 12, with reference to Embodiment 1, a pipe nose body 5 is provided in front of the bow and a sewage grid 41 with an extension is provided on the surface of the water inlets on both sides. The lower parts of the rear shoulders 4 on both sides are respectively provided with symmetrical and symmetrical total water outlets 22, and a longitudinal flow layer 23 and branch pipes 24 on both sides are arranged between it and the water inlets 21 on both sides, and the branch pipes 24 on both sides are arranged. Exhaust pipes 42 are arranged on the rear top surface of 24 respectively. Symmetrical or similar counter-rotating spiral diesel propulsion devices 31 are arranged side by side in the main water outlets 22 on both sides. The ...

Embodiment 3

[0084] The combined stern and side propulsion of the leading water propelled ship of the present invention with longitudinal flow tubes and side flow tubes will be further described below in conjunction with the accompanying drawings as Embodiment 3.

[0085] As shown in FIG. 14 , a longitudinally inverted trumpet-shaped flow pipe 24 is arranged on the longitudinal axis of the ship bottom, and a total water outlet 22 and a lower edge extending edge 28 are arranged at the tail of the ship's stern. The same type of parallel counter-rotating twin propellers 31 are arranged in the main water outlet 22, and are driven by the same type of diesel engines 35 respectively arranged on the top thereof. Side flow pipe 25 on both sides among the figure, water outlet 22, protruding body 14, water outlet 15, streamlined flow section 6, propeller propulsion device 31, exhaust pipe 42, side shovel dendrobium 43, blowdown grid 41, diesel engine 35 and The nose body 5 and the water inlet 21 are ...

Abstract

The present invention discloses a front water diversion propulsion ship and aims at providing a regular water diversion type ship which can eliminate wave making completely or reduce the wave making and eliminate wave making resistance and can also reduce the friction resistance and motivate the hydrodynamic propulsion to improve the comprehensive performance of the ship such as speed, stability and efficiency. The front water diversion propulsion ship is realized by a technical proposal as follows: a forward water inlet is arranged under the water line at the front part of the ship; and a backward water outlet or a thruster inlet are arranged and matched at the forward water inlet with a flow passage which runs through the forward water inlet and a stern or arranged at two lateral parts. Or a forward-backward thruster is arranged under the water line, or a watercourse is matched and arranged in the front of the water line, two lateral water outlets which are propelled by two sides of the front of the ship or propelled by a stern impeller are arranged, or the back ship body of the thruster is arranged as a streamline after run to motivate the hydrodynamic propulsion. The technology of the front water diversion propulsion ship can fit for designing and manufacturing a powered regular drainage ship and improving the existing ship and is especially fit for designing, manufacturing and improving the economical, large and jumbo ships.

Description

technical field [0001] The invention relates to a ship, in particular to a conventional displacement ship in which the water in front of the pilot ship is used as the propelling medium. Search the International Patent Classification for genus B63B1 / 04. Background technique [0002] At present, the conventional displacement ships sailing on the international water surface increase the length-to-width ratio of the ship to deal with wave-making and wave-making resistance, and increase the power to fight against the peak value of wave-making resistance. An insurmountable physical barrier is set for conventional displacement ships to increase their speed and enter the high-performance ship row. Moreover, the wake of the stern or bilge water or chord water is used as the propulsion medium, not only the propeller or the pump encounters cavitation, cavitation, noise and vibration, but also involves thrust deduction points, which effectively exerts the existing power , especially t...
