New description: [New technical field] This creation is about a hull', especially about a hull that reduces the resistance to water flow and accelerates the speed and load of the ship. [Prior Art] A hull design conventionally used for loading cargo or personnel, as shown in Figures 〖 and 2, the conventional hull 9 includes a load-bearing portion 91 and a submerged portion %, and the load-bearing portion 91 The submerged portion 92 is formed under the carrying portion 91, and the submerged portion 92 is formed by two symmetrical buoys 921, and the internal spaces of the two buoys 921 are connected to each other. The radial sections of the two floats are each formed in a semi-circular shape, so that the buoyancy of each of the floats 921 is determined by the semicircular cross-sectional diameter D of the float, and the load of the hull 9 is relatively increased. In addition, the hull 9 can also be cut upward by the submerged portion 92 into a chamfered stern 93 (as shown in the figure), and the stern 93 and the stern submerged water portion 92 have a water flow space r, And the ship® tail 93 is combined with a power propeller 94 and a rudder 95, so that the water flow in the water flow space R is pushed by the 5 hp power propeller 94 to drive the hull 9 forward and pass through the rudder 95. Swing left and right to control the direction in which the hull 9 travels. According to the design of the conventional hull 9 described above, in order to increase the load capacity of the hull 9, most of the manufacturers can only choose to change the semicircular cross-sectional width D of the pontoon 921 in accordance with the diameter D of the pontoon 921. The proportion of the pontoon 921 is increased in proportion, whereby the buoyancy of the hull 9 is provided through the internal space of the pontoon 921, and the load of the hull 9 is relatively increased. —3 — However, according to the diameter D of the pontoon 921, when the pontoon 921 is enlarged in proportion, the contact area of the pontoon 921 with the water flow is easily increased, and the water flow resistance of the pontoon 921 is relatively increased. Therefore, the traveling speed of the hull 9 is significantly reduced; even, the conventional pontoon 921 is easy to make the floating 921 of the floating meat 921 gradually increase due to the load, and the bottom of the hull 9 is in direct contact with the water surface. And the generation of another wave of water flow resistance, serious scene; ^ sound the smoothness of the hull 9 between the travel. These conventional bodies are also considered to have a good load capacity and a small ship resistance in the evil method, so it is impossible to maintain the ship's 9-load capacity while maintaining a good ship speed. Further, the above-described conventional hull 9 is designed to cut the stern 93 having a large inclination behind the hull 9, thereby combining the power propeller 94 and the rudder 95. However, the oceanic force that the chamfered stern 93 can provide is significantly smaller than the buoyancy provided by the submerged portion 92, so that the power snail (4) drives the hull 9 to advance the hull. 9 front lifted 'to make the Qisaki 9 secret level of the line, and affect the stability of the hull ^ travel; even, in order to provide the direction of the body 95 at the stern 93 ° space - the power spiral The music 94 can only be disposed in the water flow space R, which is closer to the hull 9 so that the power propeller 94 pushes the water flow leaf, and the effect of driving the hull 9 is not improved, and energy consumption is not only energy-consuming. It is even more difficult to achieve the speed of the ship. In view of this, it is indeed necessary to develop a hull sufficient to simultaneously reduce the resistance of the water flow and increase the load, so that the problems as described above can be solved when the hull is advanced.

"Reducing the water as much as possible, in order to improve the cutting inclination of the twisting position of the second purpose of the creation, to turn the (four) oblique hull 'system blue to reduce the stability of the stern. . The water flow efficiency of the spiral medicine = the hull of the raft, which is capable of increasing the power to achieve the aforementioned creation speed and reduce energy consumption. The carrier is used to load cargo or a person's hull. The hull consists of: a submerged portion, and the submerged portion and the submerged portion are located on the bearing with an axis along the pontoon. Axis: a symmetrical pontoon constitutes the pontoon system, the flat (four) is formed by a vertical bulge extending perpendicularly between the two pontoons, a symmetrical longitudinal wheel, 2 points 'and the plane is parallel to an outer zone at the same time, The _################################################################################################### Vertical fresh surface, in addition, the bottom of the two body - water flow space. From the separation distance as the ship _ _ can also, (4) hull-sink line, the same as the reserved section and a In the submerged section, 一's a depth reference formed by the surface of the water 嚷> the water is fine, the submerged water part is not in the g, and the other two symmetrical buoys can be used to make another 5 auxiliary aids. Auxiliary system. It is tapered downwards--cone into two, · 妓, and the body 'the lowest point of the tapered section of the aid M419733 is for the pair The vertical axis passes. Further, the hull of the present invention can even cut a stern upward from the submerged portion, and the stern is used to install a power propeller to drive the hull by the power propeller system. [Embodiment] The above and other objects, features and advantages of the present invention will become more apparent and obvious. The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. 3 and 4 are a preferred embodiment of the present invention. The ship system includes a carrying portion 丨 and a submerged portion 2 formed below the carrying portion 1 for The submerged portion 2 provides the better dynamism of the hull' so that the hull of the present invention can have an appropriate load # for loading the load 邛1 for cargo or personnel. The selection of the load 丨 is based on the technology. The field has the usual knowledge that can be easily thought of, and is not the technical characteristics of this creation, so it will not be described in detail here. 凊 Referring to Figure 4 again, the submerged part 2 is composed of two symmetrical floats ^ And the two-symmetric buoy of the embodiment Between 21, there is a Pw distance of 13⁄4 distance as a water flow space s at the bottom of the present hull to drive the hull forward by pushing the water flow in the water flow space s. In addition, the two symmetrical buoys The 21 series may each have an internal space 210, and the internal spaces 210 of the two symmetric buoys 21 are in communication with each other to supply a relatively suitable buoyancy of the hull by the interconnected internal space 210. Further, the buoy 21 has An axis χ (as shown in FIG. 3) is formed along the axis X of the pontoon—a plane F that extends longitudinally and vertically (as shown in FIG. 4). The plane F passes through the lowest point p of the pontoon 21, And the plane F is parallel to a symmetrical longitudinal axis γ between the two pontoons 21, and the plane=is dividing the ocean tube 21 into an inner area A1 and an outer area A2, so that the inner area A1 has a radial direction. The section width W1 is smaller than the radial section width W2 of the outer section A2 (see Fig. 5 for details). Wherein, the symmetrical longitudinal axis γ refers to the vertical body, and preferably passes through the center of the hull to divide the hull into a reference line of two symmetric boring tools, and the two symmetrical pontoons 21 are preferably individually Located on the two symmetrical outer sides of the hull to maintain better bearing stability of the hull. «Monthly referring to Figures 4 and 5, in the present embodiment, the pontoon 21 is slid into a tapered shape by one end of the connecting 3 hull portion (such as the tapered diameter of the figure *) To the cross section), along the axis of the pontoon 21, the plane F passing through the cone point = of the pontoon 21 is formed. Thereby, the pontoon 21 is divided into an outer zone A2 adjacent to the water flow space S_area and near the outer water flow. Thus, when the radial section width of the inner zone A1 is smaller than the radial section width W2 of the outer zone A2, the flow of water passing through the water flow space s can be made to have a smaller contact area with the pontoon 21 (4) A1. The water flow resistance is reduced, and a relative pressure difference is generated with the water flow flowing through the outer area A2 of the pontoon 21, thereby increasing the speed of the water S _ water flow and increasing the speed of the boat. In addition, the creation may also be along a submersible line L of the hull to divide the ocean tube 21 into a reserved section 211 and a submerged section 212, wherein the submerged line L refers to the submerged section 2 The depth reference line formed by no water surface (as shown in Figure *). In this embodiment, the reserved section 211 of the pontoon is located between the bearing part 1 and the submerged line L, and the pontoon 21 is tapered downward by the submerged line L to have the cone-shaped submerged water. The segment 212' causes the pontoon 21 to exhibit a longitudinal extension, so as to increase the a-foot's degree of the hull through the design of the reserved segment 211, to ensure that the hull gradually increases the submerged water due to the load. The degree of the section 2 is increased by the time that the bottom of the hull is directly in contact with the water surface, thereby reducing the resistance of the water flow at the bottom of the hull. In order to increase the buoyancy of the submerged portion 2, in the two symmetry, another auxiliary device 22 can be selectively added between the tubes 21, and the auxiliary device 22 can form a three-point support with the two buoys 21, In this way, the contact surface of the bottom of the hull and the water surface is changed to make a non-planar contact, and the stern body is stabilized through the three-point support structure, and at the same time, the buoyancy of the hull is increased. In the present embodiment, the two ridges ", 22 are preferably a tapered body which is tapered downward, and the lowest point of the tapered section of the auxiliary tool 22 as in the fourth section is preferably provided for the symmetrical longitudinal axis. Υ = over 'designed by the tapered body of the auxiliary device 22, and the water damper effect of the two 'touches' can be carried out in front of the hull, and the smoothness of the ship is increased with respect to the water flow resistance of the descending body. It is a side view of a hull of the creation, and the system can be cut upward from the submerged section 2 - the stern 3, the stern 3 3 ^ | The propeller 31 is driven by the power propeller = moving the field. For the financial implementation, the stern 3 refers to the ladder-shaped section 形成 formed by each of the floating tail ends, and the sipe 4 of the ladder-shaped section = is equipped with the power spiral purple 31, and the power position (4) Compared with (10), the power propeller 31 can exert a relatively high pushing efficiency to achieve a fine traveling speed. Moreover, ~ power propeller 3! can also choose to control the power of the power of the left and right turn 6 ^ steering to penetrate the I # rod, ^ stone direction, you can easily grasp the direction of the ship, preferably When the moving M419733 force propeller 3 installed at the end of the two pontoons 21 is the same as the direction _, the hull can be stably advanced forward' and when the hull has to turn, the system chooses to control it. The forward rotation of the power screw 31 is used to change the direction and deflection angle of the hull forward. The means for operating the power screw 31 is understandable to those skilled in the art, and therefore will not be described in detail.

At the same time, by using the feature that the radial section width W1 of the inner section A1 of the cylinder 21 is small, the contact area of the water flow between the pontoon 21 and the water flow (four) s is reduced to avoid the generation of water flow resistance, and the inner dA1 and the outer passage can be transmitted. The water flow resistance of the area A2 is different, and a relative water pressure difference is formed between the inner and outer areas, and the water flow speed in the water space S is accelerated, thereby simultaneously improving the hull load capacity and fast driving. The effect of the hull.
