Abstract

The utility model discloses a side wall type or double-body type wave reducing device for an air cushion ship, which is composed of a hull of the ship, a hydraulic device, hinges, a water pressing plate and a tail sloping plate. The utility model can effectively decrease waves which are produced when a side wall type or double-body type air cushion ship sails in high speed, and prevent ships and banks from damage.

Description

Side wall type or air cushion catamaran subtract wave apparatus

The utility model relates to a kind of device that reduces side wall type or air cushion catamaran wave making.

At present, air cushion vehicle with its at a high speed, advantage such as energy-conservation accepted by society day by day, still, because air cushion vehicle navigates by water at a high speed and brought big wave making, jeopardizes canoe and embankment, limited the development of air cushion vehicle.

The purpose of this utility model provides a kind of wave structure that subtracts of air cushion vehicle, reduces side wall type or air cushion catamaran wave making when air cushion vehicle is navigated by water at a high speed, makes wave not jeopardize ship and embankment.

For achieving the above object, the technical solution of the utility model is: side wall type or air cushion catamaran subtract wave apparatus by hull, hydraulic efficiency gear, hinge, setting-out plate, tail swash plate are formed, side wall type or air cushion catamaran hull bottom afterbody tilt to the back upper place, form the tail swash plate, the upswept height of tail swash plate should be when side wall type or air cushion catamaran operational configuration the position that has a common boundary of tailgate and horizontal surface, tail swash plate and hull bottom baseline angle should be controlled between 2-30 °; At the air cushion vehicle afterbody setting-out plate is installed simultaneously, setting-out plate one end hinge knot is on air cushion stern swash plate, the other end cuts with scissors knot mutually with the oil cylinder of hydraulic efficiency gear on being fixed on hull, hydraulic efficiency gear control setting-out plate is toward pressing down, form an angle with level, the area of setting-out plate is by the angle decision of load, ship's speed and setting-out plate and horizontal surface; Hydraulic efficiency gear is made up of motor, oil pump, oil cylinder, reducing valve, control cock etc.; The setting-out plate can fixedly mount alow that afterbody and horizontal surface form an angle, perhaps the air cushion vehicle afterbody fixedly hydrofoil replace the setting-out plate.

Working process of the present utility model is achieved like this: side wall type air cushion catamaran hull bottom afterbody tilts to the back upper place, form the tail swash plate, the position that tailgate and horizontal surface had a common boundary when the upswept height of tail swash plate should be side wall type or air cushion catamaran operational configuration, tail swash plate and hull bottom baseline angle should be between 2-30 °, at this moment air cushion vehicle afterbody air-cushion pressure moves closer to zero, because the air cushion vehicle wave making is and square being directly proportional of air-cushion pressure, this moment, air-cushion pressure reduced, wave making also reduces, but cushion lift also reduces simultaneously, in order to remedy the deficiency of cushion lift, the setting-out plate is installed, on the tail swash plate because setting-out plate and horizontal surface form an angle, under sail, because the punching press of water produces component upwards, replenishes the lift that the afterbody air-cushion pressure reduces.

The wave that the utility model produced in the time of reducing side wall type or air cushion catamaran effectively and navigate by water at a high speed prevents that canoe and embankment from being endangered.

Provide accompanying drawing of the present utility model below

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Side wall type or air cushion catamaran subtract wave apparatus by hull 7, hydraulic efficiency gear 1, hinge 2,4, setting-out plate 3, tail swash plate 5 are formed, side wall type or air cushion catamaran hull bottom afterbody tilt to the back upper place, form tail swash plate 5, tail swash plate 5 upswept height should be when side wall type or air cushion catamaran operational configuration the position that has a common boundary of tailgate 6 and horizontal surface, tail swash plate 5 and hull bottom baseline angle should be controlled between 2-30 °; At the air cushion vehicle afterbody setting-out plate 3 is installed simultaneously, setting-out plate 3 one ends hinge knot is on air cushion stern swash plate 5, the other end cuts with scissors knot mutually with the oil cylinder of hydraulic efficiency gear 1 on being fixed on hull 7, hydraulic efficiency gear 1 control setting-out plate 3 is toward pressing down, form an angle with level, the area of setting-out plate 3 is by the angle decision with horizontal surface of load, ship's speed and setting-out plate 3; Hydraulic efficiency gear 1 is made up of motor, oil pump, oil cylinder, reducing valve, control cock etc.; Setting-out plate 3 can fixedly mount alow that genus portion and horizontal surface form an angle, perhaps the air cushion vehicle afterbody fixedly hydrofoil replace setting-out plate 3.
