Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited by the examples.

[0029] A stern water supply device for propeller-propelled high-speed planing boats, the specific structure is as follows figure 1 As shown, the water supply device includes a water supply suction port 3, a water pipe 4 and a one-way check valve 5; the water supply suction port 3 is fixed on the paddle shaft of the propeller and a coarse filter is provided on the water supply suction port 3; The water pipe 4 includes a water pipe 41 in the paddle shaft, a flexible water pipe 42 and a water pipe 43 in the hull; the water pipe 41 is embedded in the paddle shaft inside of the propeller and accounts for 1 / of the propeller shaft length of the paddle shaft length. 2. The water inlet of the inner water pipe 41 of the paddle shaft is connected to the water supply suction port 3, the water outlet of the inner water pipe 41 of t...

Abstract

The invention relates to a tail water supplement device for a high-speed skimming boat propelled by a propeller, and belongs to the technical field of supplementary devices of ships. According to the tail water supplement device for the high-speed skimming boat propelled by the propeller, under the condition that a boat body leaves the water surface frequently when the skimming boat encounters too much inrush current, the situation that water suction through a seawater suction port in the bottom of the boat body is interrupted due to the fact that the boat body leaves the water surface frequently, and consequentially, cooling water cannot be provided for a main unit cooling system is avoided, and the problem that when the skimming boat encounters too much inrush current, a cylinder gets stuck due to the fact that the temperature of a main unit is too high is solved. The water supplement device provided by the invention can be applied to various skimming boats propelled by propellers and is wide in application range and high in practicability.

Description

technical field [0001] The invention relates to a tail water supply device for a propeller-propelled high-speed planing boat, and belongs to the technical field of ship supply devices. Background technique [0002] As a new type of high-performance boat, planing boats are mainly high-speed small boats based on the principle of surface gliding, including yachts, high-speed rescue boats, patrol boats, torpedo boats, missile speedboats and other practical boats. Its main features are shallow draft and high speed. [0003] It is generally believed that when the Fourier number F n >1 or After that, the bottom of the boat is affected by the hydrodynamic force, and the hull is lifted out of the water (this process is called take-off). At this time, the boat changes from the state of displacement sailing to the state of high-speed gliding, and the stage before this is called between displacement sailing and high-speed flight. Transition state between taxis. [0004] When mos...
