Abstract
The utility model relates to a ship accelerator, which is composed of two figure-eight water guiding pipes and the water guiding pipes are arranged in the ship body. The water guiding pipe has a big water inlet and a small water outlet, the water inlet is positioned below the draft level of the ship board or the ship head, and the water outlet faces towards the propeller. When the ship sails forwards, the water current of the water guiding pipe impacts the propeller blades to achieve the purposes of relieving 'cavitation erosion ' and reducing dynamic force consumption.
Description
The utility model relates to the hull field, is meant a kind of current of screw propeller and boats and ships boost installation of thrust of changing especially.
Since steam power and the invention of combustion engine powered boats and ships, people improve design by fair means or foul, and the resistance of managing to improve constantly power and reducing the hull each several part is to raise the efficiency and to increase ship's speed.Modern boats and ships mostly are to drive screw propeller by power to obtain thrust, screw propeller when static blade just, the pressure that all equated of the back side, after screw propeller rotates, because the effect of fluid, blade just, the back side forms difference of pressure, rotating speed is high more, difference of pressure is just big more, when producing vacuum on the blade back side, and when reaching water vapor pressure under this temperature, then can produce " cavitation erosion " phenomenon, " cavitation erosion " not only makes blade form empty wagons, and can produce destruction to blade, make the blade back side form the service life that cellular-shaped erosion point has shortened blade.
The purpose of this utility model is to propose a kind ofly to overcome above-mentioned shortcoming, reduces blade " cavitation erosion ", thus the boats and ships boost installation of the efficient of raising screw propeller.
The purpose of this utility model realizes by following scheme: two mozzles become splayed to be installed in the hull, and the water inlet of mozzle is big, and water outlet is young, and water inlet on the quarter or below the floating line of fore, water outlet is facing to the blade of screw propeller.When ship to overtake the time, current will flow backward along with mozzle, because mozzle is that water inlet is big, water outlet is young, so form general torrent, is impacting blade.
Below in conjunction with drawings and Examples, the utility model is further described:
Accompanying drawing is a upward view of the present utility model
1-hull 2-screw propeller 3-mozzle
4-power
3 one-tenth splayeds of two stream pipes are installed in the big hull 1, the water outlet of mozzle 3 faces toward the blade of screw propeller 2, when 2 rotations of power 4 drive screw propellers make ship to overtake, current will flow backward along mozzle 3, because mozzle 3 is that water inlet is big, water outlet is young, impacting blade so form two strands of torrent, thereby make screw propeller obtain enough water yields also because the impact of these two strands of torrent, make blade obtain a rotational force, can reach the consumption of minimizing " cavitation erosion " and minimizing power like this, increase the speed of boats and ships.
The utility model has the advantage of simplicity of design, easy to implement, do not need to change structure and the profile of hull, on obsolete vessel, also can install, can reach the purpose that anti-" cavitation erosion " increases ship's speed with littler improvement cost.
Claims (1)
1, boats and ships boost installation is by screw propeller, and mozzle is formed, it is characterized in that two mozzles become splayed to be installed in the hull, mozzle ground water inlet is big, and water outlet is young, water inlet on the quarter or below the floating line of fore, water outlet is facing to the blade of screw propeller.
