Description

Multihull

Technical field

The invention relates to a multi-hull ship which is formed by using a plurality of thin hulls spaced at a certain distance and connected by an upper strong frame.

Background technique

In the online encyclopedia "Baidu Encyclopedia", the term "multihull" provides a detailed introduction to multihulls. At present, the world's main multihulls are: catamarans, trimarans, quadrames, and pentahums. Ships, like monohulls, have a larger deck area than multihulls, better stability and wave resistance. The term "waterline surface" in the online encyclopedia "Baidu Encyclopedia" introduced the small waterline surface catamaran (SWATH) and the small waterline surface catamaran "Silaisi", which explained in detail The advantages of the small waterline surface hull boat, the small waterline surface hull boat has better wave resistance than the small waterline surface hull boat. The disadvantage of the small waterline surface hull boat is that the draught change caused by the smaller load change Larger.

technical problem

The technical problem to be solved by the present invention is to provide a multi-hull ship, which can switch between a small-water-plane multi-hull ship and a non-small-water-plane multi-hull ship. Under the influence of waves, it is converted into a small waterline surface multihull. Sailing or floating in this state has the advantages of a small waterline surface multihull. The multihull can also increase the area of the waterline surface and change to not. The small waterline area multi-hull ship can reduce the draught depth and reduce the influence of the load change on the draft. It has the advantages of not being a small waterline area multi-hull ship.

Technical solutions

To solve the above technical problems, the multihull ship of the present invention provides three solutions.

Here is an explanation of the upper hull, middle hull, and lower hull claimed in each scheme: when the multihull is converted to a small waterplane surface multihull, the hull above the water surface is the upper hull, and it is below the water surface. The hull is a lower hull, part of which is above the water surface, and part of the hull below the water surface is a medium hull. The role of the upper hull is to provide reserve buoyancy when the small waterline surface multihull is in the state of the lower hull. Provides primary buoyancy in the state, and secondary buoyancy in the state of the small waterline surface hull; in the state of the small waterline surface hull, the smaller the hull, the better the wave resistance and stability of the multihull The worse, the larger the hull of the multihull, the worse the wave resistance and stability of the multihull, the size of the midhull is determined according to actual needs; when the multihull of the present invention is converted to a non-small-waterplane multihull, the upper The hull and lower hull provide both buoyancy.

The first solution is that the multihull ship of the present invention consists of four or six upper hulls with hull pillars that can move up and down, and four or six middle hulls with hull pillars that can move up and down. Four or six lower hulls with hull pillars that can move up and down, and a strong frame connecting each hull; the volume of all upper hulls is greater than the volume of all middle hulls, and the volume of all lower hulls is greater than the volume of all middle hulls; The strong frame has connecting parts connected to the respective hull pillars of the upper hull, the middle hull, and the lower hull. The strong frame has a driving device for moving the upper hull, the middle hull, and the lower hull pillar of the upper hull up and down, the connecting part and the driving device. They are all part of the strong structure. The hull pillars can be moved up and down by the driving device through the connecting parts, and can fix each hull pillar when the hull needs to stay; each hull pillar of the upper hull, middle hull, and lower hull passes through The respective connecting parts are connected to the strong frame, and the upper hull, middle hull and lower hull can be The hull pillars can be moved up and down, and the respective hull pillars can be fixed when the hull stay is needed; the upper hull, middle hull, and lower hull hull pillars must have a certain length, and the length of each hull pillar can allow the upper hull, middle hull, The lower hull is separated by a certain vertical distance from top to bottom. The spaced certain vertical distance is to allow the multihull ship to pass through the middle hull of the waves in the sailing water when the multihull is in the state of a small waterline surface multihull. Do not touch or touch the upper hull, so that the troughs of the waves can pass under the middle hull, and do not touch or less touch the lower hull. This can reduce the impact of the waves on the multihull ship of the present invention. The upper hull, middle hull, and lower hull are from top to bottom. The larger the distance is, the higher the waves that the multihull ship can withstand. The length of each hull pillar must be determined according to the hull size, hull structure and wave resistance height. In order to ensure that the multihull ship of the invention can be converted to For small waterline area multi-hull boats, the length of the hull pillars on the upper hull must also ensure that the upper hull and the lower hull can be at the same level; The hull is submerged in the water, providing most of the buoyancy, moving the upper hull above the water surface, providing reserve buoyancy, so that part of the middle hull is below the water surface, and part of it is above the water surface, providing a small portion of buoyancy. Surface hull state; using the driving device to move the hull pillars of the upper hull and the lower hull, the upper hull and the lower hull can be at the same level. At this time, the multi-hull ship of the present invention is not a small-water-plane multi-hull state. When the area of the waterline surface becomes larger, the draught becomes shallower, and the increase and decrease in load capacity and distribution have a smaller effect on the change in draught. The multihull ship of the present invention has the advantage that it is not a small waterplane surface multihull ship. It also moves to the same horizontal plane, the water surface area is larger, and the multi-hull ship of the present invention is more stable; the powerful structure of the multi-hull ship of the present invention is equipped with a hydrofoil with hydrofoil props that can move up and down, and can be used when needed. The position where the hydrofoil stays fixes the hydrofoil props. The number and size of the hydrofoils are determined as needed. For the installation method of the hydrofoil and the method for driving the hydrofoil props, refer to the multibody of the present invention. The method of mounting and driving the hull strut. The multihull ship of the present invention can be equipped with sailing masts, stabilizers, rudders and other components used on the powerful structure of the multihull ship to allow the multihull ship to sail on the wind when it is not in a small waterline state. The outrigger can be installed on the strong frame.

The second solution is that the multihull ship of the present invention consists of four or six upper hulls with hull pillars that can move up and down, and four or six middle hulls with hull pillars that can move up and down. Two lower hulls with hull pillars and strong frames fixedly connected, and strong frames connecting each hull; the volume of all upper hulls is greater than the volume of all middle hulls, and the volume of all lower hulls is greater than the volume of all middle hulls; There are connecting parts connected to the upper hull and the middle hull hull pillars. The strong frame has a driving device for moving each hull pillar up and down. The connecting parts and the driving device are part of the strong frame. The upper hull and middle hull hull pillars are worn through. The connecting parts can be moved up and down by the driving device, and the respective hull pillars can be fixed at the positions where each hull is to stay; the upper hull, middle hull, and lower hull hull pillars must have a certain length; the driving device is used to move the upper hull and The hull pillar of the middle hull can make the upper hull, the middle hull, and the lower hull spaced a certain vertical distance. At this time, the multihull ship of the present invention is in a state of small waterline surface; when the hull pillars of the upper hull are moved using the driving device, the upper hull and the lower hull can be at the same level. At this time, the multihull ship of the present invention is not in small water. Line surface state.

The third solution is that the multi-hull ship of the present invention consists of four or six upper hulls that can move up and down with hull pillars at a certain distance, two lower hulls with hull pillars fixedly connected to a strong frame, and two The middle hull fixed on the hull pillars of the lower hull, and the strong frame connecting each hull; each lower hull can have two or more hull pillars; the volume of all upper hulls is greater than the volume of the two middle hulls, and the two lower The volume of the hull is greater than the volume of the two middle hulls; there is a connecting member connected to the hull pillar of the upper hull on the strong frame, and a driving device of the hull pillar that moves the upper hull up and down on the strong frame. The connecting member and the driving device are strong frames Part of the upper hull hull pillar can be moved up and down through the connecting part by the driving device, and the hull pillar can be fixed where the upper hull stays; the lower hull pillar is directly fixed on the strong frame, and the middle hull is directly fixed on the lower side. The proper position of the hull pillars of the hull. The crests of the waves can pass over the middle hull without touching or less touching the upper hull, so that the wave troughs can pass under the middle hull without touching or less touching the lower hull, which can reduce the impact of the waves on the multihull ship of the present invention; The hull pillar is fixed on the strong frame and the middle hull is fixed on the hull pillar of the lower hull. Although it does not have the function of moving up and down, it saves materials and enhances the firmness of the connection, which is conducive to making the multihull ship of the present invention larger. It is still possible to rely on the up and down movement of the upper hull to achieve the conversion between a small waterline surface multihull ship and a non-small waterline surface multihull ship; the hull pillars of the upper hull and the lower hull must have a certain length; the use of a driving device can allow The upper hull leaves the water surface and provides reserve buoyancy. At this time, the lower hull provides most of the buoyancy below the water surface. A part of the middle hull is below the water surface and a part is above the water surface to provide a small amount of buoyancy. The multihull is a small waterline surface multihull ship. The state has the advantages of a small waterline surface hull ship; using the driving device to move the hull pillars of the upper hull down, The upper hull and the lower hull are at the same level. At this time, the multihull ship of the present invention is in a state of not being a small waterline surface multihull ship. When the multihull ship of the present invention is not a small waterline surface multihull ship, the increase and decrease of the load capacity and The influence of distribution on draught changes becomes smaller. At this time, the multi-hull ship of the present invention has various advantages that are not small-water-plane multi-hull boats.

The multi-hull ship strong frame of the present invention has connecting members connected to the hull pillars. The hull pillars can be moved up and down through the connecting members, and the hull pillars can be fixed at the position where the hull is to stay. The strong frame is connected to the hull pillars. There can be many types of components, and two are specifically introduced here. The first type of connecting part is a connecting cylinder with a round hole with a wear block installed at both ends, and a cylindrical pin that can be inserted into the circular hole on the connecting cylinder. When the hull pillar has multiple positions to reach the hull to stay A circular hole of the same size as the circular hole on the connecting cylinder can be inserted into the circular hole of the connecting cylinder and the circular hole of the communicating hull pillar to fix the connecting cylinder and the hull pillar. The connecting cylinder can be sleeved. The cylindrical structure outside the hull pillars. The inner walls of the two ends of the connecting cylinder are equipped with wear blocks. The abrasion blocks are in contact with the hull pillars. The hull pillars can be moved up and down inside the connecting cylinders. In order to connect firmly, the connecting cylinders must reach the required length and strength. The second connection component is a connection cylinder with wear-resistant blocks installed at both ends, and a square protrusion controlled by a spring plate on the side wall of the connection cylinder. A part of the square protrusion extends into the connection through a square hole on the side wall of the connection cylinder. Inside the cylinder, there are a plurality of square pits corresponding to the square projections when the hull pillars are moved to the desired position. The square projections are snapped into the square pits under the elastic force of the spring plate, and the hull pillars are fixed and the square projections are pulled apart. The hull pillar can be moved up and down.

There can be multiple driving devices for moving the hull pillar up and down on the multi-hull strong structure of the present invention. Two types are now introduced. The first driving device is a winch with a rope and a pulley for turning the rope. The pulley is installed on the connecting member. The rope bypassing the pulley can change the horizontal pulling force to the vertical pulling force, which is convenient for pulling the hull pillar. The top of the hull pillar and the root connected to the hull each have a hook for hanging the rope. In order to facilitate hanging the rope to the top of the hull pillar Each hook is equipped with a long rod with a hook, and the rope passes the pulley to pick up the hook connected to the top of the hull pillar with a long rod. Tighten the rope and the hull pillar will Move down, the rope passes the pulley and uses a long rod to pick up the hook with the root of the hull pillar, tighten the rope, the hull pillar moves upward, and the winch can be driven by human or motor. Another type of driving device is a gear driven by a motor or a hand crank on the powerful structure. The gear meshes with the rack on the hull pillar. When the gear is rotated, the hull pillar moves.

In order to further reduce the influence of waves, the lower hull of the multihull ship according to the present invention may be equipped with anti-rolling fins. In order to drive the multihull ship according to the present invention, a thruster may be installed at the stern of the lower hull, and a propeller may be installed on the lower hull pillar.

Each hull of the multihull ship of the present invention can adopt various shapes according to requirements. For example, the lower hull can refer to the shape of a torpedo or a submarine, and the hull shape of a semi-skid ship can also be referred to. The upper hull and the middle hull can refer to the wave-piercing ship The shape of the hull or the shape of the planing or semi-planing ship can also be a slender spheroid.

For all hull types of the multihull ship of the present invention, after the multihull ship of the present invention is manufactured, the optimal load capacity of the small waterline surface multihull ship can be measured in still water. At this time, half of the volume of each hull is below the horizontal plane. , Half of the volume of each hull is above the horizontal level, and the weight of each person's seat and the weight of the materials placed at each position are measured and marked, so that in actual use, based on the change in water density, the total Load capacity, weigh people and materials when boarding the ship, go for more and less, then spread out with reference to the load capacity of each location. The difference in personnel weight can be compensated by the items carried, or several water tanks can be adjusted. When the multi-hull ship is in the state of a small waterline surface multi-hull ship, the total load capacity and the load capacity at various positions can have a certain range of change, and this range is determined by the size of the middle hull, which is large. The range of total deadweight and the deadweight of each position is large. The specific value can be calculated according to the volume of the hull. In actual application, it is affected by factors such as wind and waves. The change range of the total deadweight and the deadweight of each position must be Appropriate reduction. If the total load exceeds the bearing range of the middle hull in actual application, the upper hull can be moved down to the plane on which the lower hull is located, and the multihull ship can be converted into a non-small waterplane multihull ship.

The upper hull, middle hull or lower hull of the multi-hull ship according to the present invention may have one or more hull pillars as required.

One end of the steel plate is fixed inside the polystyrene foam constituting the hull; the hull pillars of the upper hull 1, the middle hull 2, and the lower hull 3 of the multihull ship are connected to the strong frame 5 through the connecting member 6 on the strong frame 5 The hull pillar can be moved up and down by the driving device; in order to reduce the resistance in the water, the two lower hulls 3 of the bow are closer than the two lower hulls 3 of the stern; as shown in FIG. 8, the multihull The connecting part of the ship is a steel connecting cylinder 7 with copper-inlaid graphite wear-resistant blocks installed at both ends, and a steel square protrusion 12 controlled by a spring steel plate 11 on the side wall of the connecting cylinder 7, a part of the square protrusion 12 The square hole on the side wall of the connecting cylinder projects into the connecting cylinder 7, and where the hull needs to stay, the hull pillars of each hull have square recesses 13 corresponding to the square protrusions 12, and the square protrusions 12 are in springs. The steel plate 11 is snapped into the square recess 13 under the action of the elastic force to fix the hull pillar, and the square protrusion 12 can be pulled up and down to move the hull pillar. As shown in FIG. 7, the driving device of the multi-hull ship is composed of a winch 14 with a rope and a pulley 15 for steering the rope. The pulley 15 is installed on the connecting cylinder 7. The rope can bypass the pulley 15 to change the horizontal tensile force to vertical. The direction is convenient for pulling the hull pillar. The top of the hull pillar and the root connected to the hull each have a hook 16 for hanging a rope. One end of the rope can be tied into a small ring for connecting the hook 16 if it is not reachable by hand. For the hook, a long rod with a hook can be prepared. The rope passes the pulley 15. The long rod can be used to pick the rope to connect with the hook 16 on the top of the hull pillar. Tighten the rope and the hull pillar will move downward. The rope passes the pulley 15 and the long rod can be used. The rope is connected to the hook 16 at the root of the hull pillar, the rope is tightened, and the hull pillar moves upwards; the winch 14 can be driven manually or by a motor through a speed reducer, on the four corners of the powerful structure of the multihull ship of the present invention Each has a winch, and each winch can control the upper hull 1, the middle hull 2, and the lower hull 3 closest to it; the upper hull 1, the middle hull 2, and the lower hull 3, respectively. The hull pillars must have a certain length. When a hull pillar is moved using a driving device, the length of each hull pillar can allow the upper hull 1, the middle hull 2, and the lower hull 3 to be spaced from top to bottom. Vertical distance, spaced vertical distance, so that the crests of the waves can pass through the middle hull 2 without touching or less touching the upper hull 1, and the wave troughs passing under the middle hull 2 and not touching or less touching the lower hull 3.

If someone catches a fish, In order to prevent the multihull ship from rolling, you can put the upper hull 1 under your control into the water and fix it. After catching the fish, adjust the weight with the water tank, and then move the upper hull 1 up. One of the five people will start the boat. At the same time, he can also help other people collect fish and deliver supplies. The multi-hull ship's strong frame is equipped with two hydrofoil pillars 19 with front and rear hydrofoil struts. The two hydrofoil struts of each hydrofoil 19 pass through the hydrofoil connection part on the superstructure 5 and the hydrofoil connection part and The connecting parts of the hull pillars of this multi-hull ship have the same structure and can be moved up and down and fixed. The following describes the use method of the hydrofoil 19. The hydrofoil 19 is usually stowed close to the strong frame 5. The hydrofoil 19 is used when the waves are small. When in use, move the upper hull 1 and the lower hull 3 up. At the highest point, move the middle hull 2 down, so that the middle hull 2 is below the upper hull 1 and the lower hull 3, and the hydrofoil 19 is lowered below the middle hull 2 and the distance from the bottom of the middle hull 2 is greater than twenty centimeters. When the speed is getting faster and faster, the hydrofoil 19 will lift the multihull up to the stage, when the upper hull 1 and the lower hull 3 are lifted off the water, and part of the four middle hulls 2 are above the water surface, and some are below the water surface. At this time, the speed of the multihull is controlled so that the four middle hulls 2 remain partly above the water surface and partly below the water surface or at a time when the waves are high above the water and below the water for a while. At this time, the hydrofoil 19 provides a large Part of the buoyancy, the medium hull 2 provides a small part of the buoyancy. The main role of the medium hull 2 is to maintain the balance of the multihull.

Do n’t touch or touch the upper hull 1 so that the troughs of the waves can pass through the bottom of the hull 2 without touching or less touch the lower hull 3. Then raise the upper hull 1 at the same speed at the same time. At this time, the draft of the multihull The depth gradually increases. When the water surface does not exceed half of the hull 2, the draught no longer increases. Eventually, the upper hull 1 is moved up to the highest position to reach the place closest to the strong frame 5, and then the hull pillars of the hull 1 are fixed. When the multihull is small waterline The hull boat is less affected by waves at this time. When the catch slowly increases, you can slowly put the two upper hulls in the middle of the hull boat into the water to allow the increased buoyancy to offset the increased weight. To the shore, first move the upper hull 1 down to the level of lower hull 3, and then move the middle hull 2 to the level of lower hull 3. At this time, the multihull is not a small waterline surface multihull, which is convenient. Get on and off the boat. With this embodiment, we can easily make four or six upper hulls with hull pillars that can move up and down, and four or six middle hulls with hull pillars that can move up and down. , A multihull composed of two lower hulls with hull pillars fixed on a strong frame, and a strong frame connecting the hulls. When making four upper or middle hulls that can be moved up and down, reference may be made to the structure and distribution of the upper or middle hull in the embodiment shown in FIG. 1. When making six upper or middle hulls that can move up and down, the structure and distribution of the upper or middle hulls according to the embodiment shown in FIG. 3 can be referred to.

FIG. 5 is a schematic top view of an embodiment of the third solution of the multihull ship according to the present invention. FIG. 6 is a schematic side view of the embodiment shown in FIG. 5. The multihull ship is composed of four belts spaced at a certain distance. There are upper hull 1 with hull pillars that can move up and down, two lower hull pillars 3 fixedly connected with strong frame 5, two middle hulls 2 fixed on lower hull pillars, and strong frames 5 connecting each hull; 5 and hull pillars are made of steel, the lower hull 3 can be made of steel or aluminum alloy hollow torpedo-like structure, the interior of the lower hull 3 can be divided into several cabins according to needs, and the middle hull 2 can be made of polystyrene foam plastic coated with glass steel. It can also be made of steel plate. The shape of the middle hull 2 can refer to the shape of the hull part of the warship. In order to improve the longitudinal stability of the multihull, the two ends of the middle hull can be heightened or thickened to increase the volume. 1 It can be made of polystyrene foam coated with FRP. The shape of upper hull 1 can be slender spheroid or other various hull shapes. The hull pillars of upper hull 1 pass through connecting parts 6 and The frame 5 is connected; as shown in FIG. 8, the connecting member is a steel connecting cylinder 7 with copper-inlaid wear-resistant blocks installed at both ends, and a steel square controlled by a spring steel plate 11 on the side wall of the connecting cylinder 7. The convex block 12 and a part of the square convex block 12 protrude into the connecting cylinder 7 through the square holes on the side wall of the connecting cylinder. Wherever the upper hull 1 needs to stay, the hull pillars of the upper hull 1 correspond to the square projection 12 Under the action of the spring steel plate 11, the square protrusions 13 and the square protrusions 12 are fixed in the square depressions 13 to fix the hull pillars. The square protrusions 12 can be pulled up and down to move the hull pillars. The steel connecting cylinder 7 can be directly welded to the strong frame 5. In order to connect firmly, the connecting cylinder 7 must reach the required length and thickness. The driving device is a gear 17 driven by a motor installed on the connecting cylinder 7 of the powerful frame 5. The gear 17 driven by the motor meshes with the rack 18 on the hull pillar. The four motors of the multihull boat driving device are at the same speed and speed. The direction of rotation allows four upper hulls 1 to move up or down at the same speed at the same time; the volume of the four upper hulls 1 of the multihull is twice the volume of the two middle hulls 2 and the volume of the two lower hulls 3 is two. The hull pillars of the lower hull 3 of the multi-hull hull are directly welded to the strong frame 5, the middle hull 2 is fixed to the hull pillar of the lower hull 3, and the distance from the middle hull 2 to the lower hull 3 is equal to The vertical distance when the hull 2 moves from the upper hull 1 to the highest point; the length of the multihull is twice the width, and the length of the hull pillars of the lower hull 3 of the multihull is one half of the width of the hull. The length of the hull pillars of the hull 1 on a multihull ship allows the upper hull 1 to move down to the plane on which the lower hull 3 is located. When the multihull is in a small waterline state, in order to accurately adjust the load capacity and the load distribution , Four corners on the powerful frame 5 Water tank, in the state of small waterline surface, when the personnel and materials move, the upper hull 1 can be moved down to the water surface. After the personnel and materials are adjusted, the upper hull 1 can be moved up; using the driving device can move the upper hull 1 downwards. At the level where the lower hull 3 is located, the multihull is not a small waterline surface multihull, and the draught is shallow. At this time, the change of the draught is not sensitive to the load capacity and weight distribution, which is convenient for personnel and materials to board and disembark. And change the distribution. With this embodiment, we can easily make six upper hulls with hull pillars spaced a certain distance apart, two lower hulls fixed to the strong frame by the hull pillars, and two fixed to the lower hull. A multi-hull ship consisting of a medium hull on the hull pillars and a strong frame connecting the hulls into one. When making six upper hulls with hull pillars that can move up and down, reference may be made to the structure and distribution of the upper hull in the embodiment shown in FIG. 3.
