Abstract

The utility model discloses a catamaran structure. A left lower body and a right lower body of the catamaran structure are hinged with hinged seats on the left side and the right side of a fixed base at the bottom of an upper catamaran body through connecting rods extending above float bowls, wherein two rows of hydraulic cylinders, of which the two ends are respectively connected with the fixed base and the connecting rods of the lower bodies are symmetrically mounted on the inner sides of the two hinged seats of the fixed base. When the catamaran structure navigates at a high speed, the two lower bodies can synchronously swing towards the outer sides through driving the hydraulic cylinders, so the center of gravity of a catamaran can be reduced, the pitching and the heaving of the catamaran body can be reduced, and thereby the stability of the catamaran body is improved.

Description

A kind of twin hull construction

Technical field

The utility model relates to the structure of catamaran.

Background technology

Catamaran is a kind of high-performance ship, and it comprises the lower body of subduction in water, the pillar that is higher than the upper hull of the water surface and passes through water surface connection lower body and upper hull.Its waterplane area is less, and the high speed running resistance is little, seakeeping performance is good, and it also has broad deck plane and abundant usage space simultaneously, by the extensive concern of countries in the world.Yet the waterplane area of catamaran is little, center of gravity is high, and when navigating by water at a high speed, it is also more outstanding that motion is swung in its pitching and hanging down, and the stability of boats and ships is relatively poor.Swing motion for the pitching that reduces catamaran with hanging down, improve the stability of catamaran, mainly adopt the stabilizing fin of installing constant weight on the side under water of catamaran additional at present.Yet the stabilizing fin of installing additional had both increased the weight of boats and ships, increased the resistance of ship's navigation again, had promptly influenced the route speed of boats and ships, had increased the energy consumption of catamaran sailing again to a certain extent, and not environmental protection is also uneconomical.

Summary of the invention

The utility model purpose is intended to provide the good twin hull construction of a kind of stability.

Twin hull construction described in the utility model, comprise left and right two lower bodies and upper hull, it is characterized in that: the bottom of described upper hull is provided with permanent seat, the and arranged on left and right sides of permanent seat is provided with hinged seat, left and right two lower bodies include the pitman that protrudes upward above floating drum and the floating drum, and its pitman is by being articulated on the hinged seat; The part of the two hinged seat inboards, below of permanent seat is symmetrically arranged with two discharge opeing cylinder pressures, and the two ends of each hydraulic actuating cylinder in each discharge opeing cylinder pressure are hinged with the pitman of permanent seat and lower body respectively.

Twin hull construction described in the utility model, its lower body is hinged by the permanent seat of pitman and upper hull below, and between pitman and permanent seat hydraulic actuating cylinder is installed, by driving the relative upper hull swing of lower body that hydraulic actuating cylinder can make catamaran.When catamaran navigates by water at a high speed, can make the swing synchronously laterally of two lower bodies by driving hydraulic actuating cylinder, thereby can reduce the center of gravity of boats and ships, reduce the pitching and vertical the swinging of hull, thereby improve the stability of hull.And when boats and ships need reach port, can pass through hydraulic actuating cylinder again, and drive lower body inwardly to swing, draw in, still can pull in to shore easily.And, by swing lower body under water, can not change the waterplane area of catamaran substantially, the resistance when navigating by water at a high speed is equally little.

Description of drawings

Fig. 1 is a kind of structural representation of catamaran;

Fig. 2 is the structural representation of another kind of catamaran.

The specific embodiment

As Fig. 1, a kind of twin hull construction, it comprises left and right two lower bodies 1 and upper hull 2; The bottom of upper hull is provided with permanent seat 3, and the and arranged on left and right sides of permanent seat is provided with hinged seat 4, and left and right two lower bodies include the pitman 12 that protrudes upward above floating drum 11 and the floating drum, and its pitman is articulated on the hinged seat 4 by closed rolling bearing 5; The below of permanent seat, be positioned at the part of the inboard of two hinged seats, be symmetrically installed with two discharge opeing cylinder pressures respectively, the two ends of each hydraulic actuating cylinder 6 in the two discharge opeing cylinder pressures are hinged with the pitman of permanent seat and lower body respectively.

As Fig. 2, hydraulic actuating cylinder 6 can be hinged by the pitman 12 that stretch out pipe link 7 and floating drum 11 tops, and the two ends of pipe link 7 are hinged with hydraulic actuating cylinder 6 and pitman 12 respectively, with the common formation of hydraulic actuating cylinder two bar linkage structures.When lower body need be swung, by the cylinder pushes connecting rod, connecting rod promoted the lower body swing again, and the amplitude of fluctuation that it can increase lower body makes the easier promotion lower body swing of hydraulic actuating cylinder.

As Fig. 2, the shape of described lower body floating drum can be the flat structure of circle down, and it can reduce drinking water, and increases the damping of rolling, strengthens the stability of boats and ships.

In addition, the spheroidal floating drum, the bigger angle of swing the time, there is possibility that emerges the side of floating drum, in case floating drum side emersion with influencing the draining of boats and ships, reduces buoyancy, the implementation resistance of increase boats and ships is unfavorable for the navigation of boats and ships.The above-mentioned floating drum of the flat structure of circle down, its relative spherical buoy can be swung bigger angle and the side does not emerge, and its amplitude of fluctuation is bigger, and the ability that Stability of Ship is regulated is stronger.
