Description

It relates to a semi-floating trim hydrofoil that speeds up ships and saves fuel.

Vehicles have undergone a rapid structural change from the eco-boom around the world, and vehicle development has improved fuel efficiency. Ships are water, wind speed, and rowing when they return to the past, but are currently used for yachts and competitions.

Japanese Utility Model 5-58597 Hull trim control and hull vibration reduction JP 2003-54492 planing boat Patent No. 3803251 Improved hydrofoil device JP 2009-96396 Underwater vehicle The existing fully submerged hydrofoil hydrofoil is about 50 knots, has high power and high fuel efficiency, and has a wing plate fixed underwater. It is a special ship that is inconvenient. This application installs a trim hydrofoil device on a ready-made large and small vessel, and stores it on the folding water during stormy weather and berthing, safe structure for speedup and fuel saving, and free angle adjustment It was a semi hydrofoil trim hydrofoil that would be submerged.

The recent rise in the price of fats and oils has no factor of price reduction in the future, and the number of users of small ships is decreasing. From the rise in fuel prices, vehicles and the like have become hybrid, stop running, and electric vehicles, and ships also require low fuel consumption engines. However, the ship is used for a long period of time, and it is levitation sailing with the resistance of water received by the hull, and hydrofoil levitation that reduces resistance like tire traveling is used for passenger ships etc. However, an engine with a high output is required for the engine output to be constantly levitated.
And since the hull is fully surfaced at high output speed for sailing, it has high output and high fuel consumption, and there is no adoption other than passenger ships, ships, etc.

The speed up of off-the-shelf propeller propulsion vessels, etc. is to make semi-floating trim hydrofoil cruising to reduce the weight of the hull. The side wall に し て is a fixed bearing and is configured to be accommodated by an actuator.
The structure of the metal flat support plate and the hydrofoil surface is hinged, and the blade surface is fixed by folding the support and trunnion cylinder rod of the support and the support and fixing plate of the four-bar link on the support surface. Te, fixed at cruising includes a receiving base plugged struts on the front side wall near the waterline top, or a supporting lifting fixed slide fastener shaped rotation of the side walls and struts, the axis of the bearing pipe stand hydraulic As a support and fixing to the electric actuator, the hydrofoil surface equipment is equipped with a submerged hydrofoil surface that can be freely adjusted by adjusting the lift angle of the prop angle, hydrofoil folding angle, and lift wing area of the flap. From the output adjustment and trim of the tip and tip blade angle to the optimum floating blade angle, at least 30% speed up and fuel efficiency improvement,

A structure that can be easily installed and removed from a small ship of a ready-made ship to a large ship, and that the hydrofoil surface can be folded in a few seconds after high-speed sailing and the struts can be rotated at the same time for sudden changes in weather during navigation. The thickness of the left and right side ridges of the existing FRP ship intended to be thin, light and fast is thin, and the pipe bearing on the draft to fix the column is completely fixed with the fixed plate in the inner hold. It is waterproof, and depending on the hull form, as hydraulic, pneumatic and electric actuators from the draft dock, large steel ship high-speed cargo ships, passenger ships, etc. do not require struts, hydrofoil plates As a semi-levitation ship with trim, stabilizer and flap hydrofoil, a hinge plate was welded under the surface of the water, and it was easy to fold to the side wall with a four-bar link.

And depending on the shape of the hull, the single half-floating trim hydrofoil plate equipment at the center of the left and right side, which is the center of gravity before and after the hull, is of width and area, the hydrofoil fixing plate and the front and rear flap plates In small FRP ships, etc., it is possible to manually adjust the floating angle of the hinge screw shaft, which can be adjusted manually, and in the case of steel ships, etc. Adopted as a remote control, the column plate that is rotated by the cylinder of the shaft shaft of the rod, the hydraulic cylinders of the column, the link support fixing plate of the hinge connection, the hydrofoil plate The folding, rotation, support and fixing and storage are the same as those of the equipment such as the hydraulic equipment.

The trim hydrofoil device described above has a structure in which the support plate and the hydrofoil plate are folded and stored, and the hydrofoil plate is directly connected to the bracket without a support plate and a hinge, In addition, support pipes and hinge moving parts use shock absorbing rubber pipe materials, etc., FRP ships are hinged bases with bolts on the draft of the side walls, steel ships, etc. The material of the hydrofoil plate is from metal (steel, aluminum, alloy stainless steel, etc.), or a lift wing configuration consisting of resin, foam, rubber material and composite material, and metal and synthetic material. Damage to the hull due to impacts from waves, collisions with driftwood, water leaks, etc. should be a major accident that should not occur, and the installation location is a safe place such as fishhouse, shipyard etc. with double and triple safety measures And the hydrofoil can be stored Only was a thing of the side wall side of the ship and the integral become curved shape. The installation of the side wall of the existing large steel ship described above is a simple structure of steel welding, and has a structure that is subject to waves and levitation resistance due to the strength of the link support and fixing mechanism. The floating pressure is received by the pressure receiving area of the chamber and the weld fixing portion of the hinge plate in the underwater part.

The feature of the present invention is that the struts and hydrofoil are stored on the draft, and unlike the high-speed fixed hydrofoil of a full surface floating ship, the flap wing surface is piped in the lift wing of a hydraulic pipe or hose. It is good, but fatigue of the bent part of the hinge part should be avoided as much as possible. Leakage such as breakage may cause an accident, and it is necessary to properly apply a lift-shaped resin plate and foam plate material to the flat metal blade surface. Adhering to the upper and lower surfaces, the lift wing surface is designed to reduce drag, and it is as simple as possible by using a flap plate that is manually screw-fixed based on the ship speed, rotation and hydrofoil surface angle .

  This will be described based on the drawings and reference numerals.

[Fig. 1] shows that FRP, steel and aluminum alloy single-sided hydrofoil equipment are fixed to the hull side and deck surface at appropriate bow and stern locations such as off-the-shelf light ships and existing small FRP hulls. As a fixing method, the right and left side hydrofoil equipment suitable for each hull structure is such that the pipe shaft (7) of the strut from the left and right side side (12) part has pipe bearings on the side and deck side. As a fixed base, a rotating structure of hydraulic / pneumatic and electric motors, or as a support plate rotating from the expansion / contraction of the hydraulic cylinder (5b), the connection between the support (2) and hydrofoil (3a) is hinged ( 6) Rotating folding structure of flat plate surface to match the hull shape of the hull is rotated to fix the control valve and fixed with the brake lining cylinder (5c). As a slide support fixing (8), the ready-made ship has a hydraulic rudder Hydraulic control equipment such as a battery power source for starting, etc. are connected to the right and left prop shafts, and the method of simultaneous rotation with one actuator and the left and right separate operating methods (Fig. C) are ready-made The technical support plate of [Fig.2] is a flat metal plate bent from the deck to the bottom of the draft under the side surface (12) shape, and the hydrofoil width area The wing shape and area are approximately the same width as the strut, the link connection support plate in the middle part of the strut plate and the link connection support plate on the wing surface are the expansion and contraction of the hydraulic cylinder according to the hull weight, output and hull form With a four-bar linkage mechanism from the top, the impact of the folding structure and other waves is distributed, and the trunnion type hydraulic cylinder (5a) on the top of the column is extended and retracted so that the angle of the hydrofoil surface can be adjusted freely. It becomes a switching wing surface between lift and drag with a free rotation angle.

And the structural frame material of the hydrofoil surface is made of aluminum alloy, stainless steel, etc., and the blade surface is made of a combination of FRP material and aluminum material in the bracket part, lightened by the lift wing structure filled with foam material, etc. For the prop material that is completely fixed between the hull side and the deck surface, a hard metal material is used, and a simple, light-lifting plastic, foam, rubber, etc. are placed in place on the metal plate of the hydrofoil. Bolt screw (B) to fix the hinge fixed wing plate and flap plate to the lift angle of the speed on the ship by attaching the flap to the output of the machine, providing a lift flap, making it a simple manual hinged flap plate (A) Lifting angle adjustment trim hydrofoil.
Folding and turning storage from underwater to water, the wings are folded at the same time as the props rotate while sailing. It was assumed that contact with the quay was eliminated with materials.

[Fig. 3] is a small boat with a trim hydrofoil hinged on the draft at the center of the small boat. The strut plate width and hydrofoil blade width are within the distance from the draft surface to the side wall of the deck surface. if it falls within, but a configuration of folding and rotation of the similar to the strut, however, the width of the hydrofoil surfaces from also becoming a resistance under draft, by eliminating the post, the side of the ship to the appropriate side wall side of the ship In accordance with the bend, it was made into a hydrofoil surface for folding storage with a hinge fixed with a ridge on the water surface.
The area of the front and rear flap plates can be trimmed, and should be of an appropriate width depending on the hull form, and remote control of off-the-shelf hydraulic / pneumatic equipment or manual screw adjustment (AB) As a thing, a simple lift plate made of light plastic, foam, rubber, etc. on a metal plate is used as an adhesive lift plate configuration. As a fixed type, for FRP ships, etc., shock-absorbing elastic materials (hard elastomer, rubber material) etc. are used for the cushion part of each link connecting part, and the impact from the collision of waves, driftwood, etc. to the hull Was supposed to be less.

[Fig. 4] shows the shape of a side wall dredging that does not require a support plate such as a large steel ship (1b), with the bow and stern hydrofoil surfaces being hinged at appropriate positions below the dredged water surface. In the middle of the wing surface, a four-bar linkage mechanism with a hinged link support plate is installed, and a plurality of flexible trunnion-type hydraulic cylinders are installed at the top of the cage. It is fixed underwater with hydraulic pressure of the cylinder with the same pin connection, and it is folded and retracted by expansion and contraction, and the structure without the rotating support plate becomes the lift adjustment angle of the angle below the water surface from the expansion and contraction of the cylinder rod. The flap is convenient for fine adjustment , and is a remote control by a hydraulic / pneumatic device or the flap plate of the above-mentioned simple manual hinge connection.

The large container ship's dredger is flat and welded with the hinges of the hydrofoil blades to the dredger, the above-mentioned lift structure and the storage structure that does not slow down in the folding storage navigation during waves and stormy weather In the welding of metal ships, there is no fear of inundation or leakage, and the structure of the lift hydrofoil is a simple metal plate bonded to the lift plate, or an airfoil-like hollow buoyancy structure, The structure is such that there is no hindrance such as contact with the quay at the time of berthing.
Assuming that a 6m draft, a ship length of 180m, a width of 20m, a hull weight of 5000t, and a 25-knot container ship with a height of 1m, the trim and stabilizer will be lighter by 1000t, reducing fuel costs at the same speed.

The hinge fixing strength and the resistance and load on the wing surface are the link support fixing and hinge of the strength that supports buoyancy of 250t or more, which is a quarter of 1000t, on the four hydrofoils at the tip of the container ship and the anchor. As a connecting part, it is assumed that it is received at a head chamber pressure area of 3000 square centimeters of three cylinders, it can be stored while sailing, the flap adjustment is also easy and the screw adjustment is easy, and it is easily installed on the old ship The structure was made possible.

And, the hydrofoil that folds a small FRP ship of about 10 tons with the above-mentioned rotating prop is roughly proportional to the above, strength burden, speed, fuel consumption, and the difficulty is in the wave because of the semi-levitation voyage, It becomes the thing of the run which stored.
For a semi-levating cruising of about 30cm in a 10t hull (15m x 4m x 1.3m), the shaft center part, hinge part, slide frame material part fixed to the prop and hydrofoil are 1.0t each on the left and right and front and rear wings. The strength of the thin old hull FRP material fixing bolts, struts, and wing faceplates is not sufficient, and the left and right hull sides on the deck outer surface and the inner surface of the hold and ginger etc. The slide frame material of the support post should be a secure place to be secured even if it is damaged and flooded, and the wing and support post should be hinged at an appropriate position, and the four-bar link and hinge fixed at an appropriate position on the wing surface The tip of the wing was fixed by a slide part on the side surface of the upper part of the water.
The semi-levitation of a 10-ton ship will speed up the existing output from 20 knots to 25 knots, reach the destination quickly, and save energy by adjusting the output and levitation.

Since existing ships are berthing and mooring, hydrofoil ships are used for passenger ships, ships, etc. that require special high speeds. It is also used for most small and large vessels. Container vessels, etc. need speed, and fuel efficiency is an important part of the overall cost. If the knot navigation and fuel efficiency are improved by 30%, the equipment cost of the ready-made steel ship will be a freight of simple design and construction for new ship or remodeling, and it is inevitable from the comparison of cost effectiveness It can be recovered in a few years, and if it is a hydrofoil facility of any shape for the current 35 knot sailing ship etc., it will be possible to navigate 45 knots, trim, stabilizer, speed up , The most suitable configuration for aircraft carriers, etc. It will also be a means to solve the current increase in fuel costs, and if a new ship is designed as a trim hydrofoil, it will be possible to combine high speed and low fuel consumption from long-term hydrofoil navigation with a more stable structure and ship type Trim hydrofoil device that can be configured as a trim type or a floating type.
