Abstract

The utility model provides an adjusting mechanism for control hard side wings of a water-borne vessel, which is composed of a circular arc circular arc-shaped track and a rolling body which is arranged in the circular arc-shaped track to roll. The utility model has the advantages of simple structure and convenient adjustment. The utility model utilizing the upward and downward floating of the gravity center of the rolling body following the hard side wings makes back and forth movements, making clockwise force moment and counterclockwise force moment of the hard side wings approximately equal when the hard side wings float following the fluctuation of an interface. Thus, the utility model realizes the full reaction efficiency of the water-borne vessel.

Description

The regulating mechanism of control air cushion vehicle hard flank

The utility model belongs to aircraft, is specifically related to a kind of regulating mechanism of controlling air cushion vehicle hard flank.

The bearing capacity that air cushion vehicle relies on pressurized air to produce, can make the air cushion vehicle disengaging ground or the water surface and free running, yet, air-sprung skirt and ground or the water surface are not airtight fully, therefore hull itself must have ability, constantly provide pressurized air to air cushion, this is full of compressed-air actuated air cushion and has the buoyance lift effect, and ship is navigated by water on rugged interface.Early stage air cushion vehicle is to be contained in the inside jet nozzle of air cushion bottom periphery by a row to form air cushion, and this nozzle can not only be supplied with the air of supporting hull, causes gas curtain to reach the air tight purpose around air cushion simultaneously.And widely used lift system is the high pressure gas cell-type at present, by the pressurized air that blowing engine gets, continuously sends in the air chamber, and the air in the air chamber can be revealed in the slit between flexible skirt skirt and interface.The air cushion vehicle of quovis modo, its caisson feed supple sirts mostly is flexible material and makes, in the navigation process, the air cushion bottom often is subjected to the rich folding of continuous fast speed, thereby make it at sea than navigating by water worn-down severity by land, service life is short, has influenced the safety of air cushion vehicle, has reduced the navigation technology performance of air cushion vehicle, at this phenomenon, air cushion is used flexible composite instead and is made, but still can't address this problem, and the crack often takes place the plastic cement mother metal of lining, seawater can infiltrate in this crack, quickened mother metal and added peeling off of hadron material, the air-sprung wearing and tearing become the long-term problem of paying close attention to of people, for this reason, the design people has designed the hard flank that can be similar to platy structure in the hull both sides, cancelled the flexible skirt on traditional air cushion vehicle,, need regulate the buoyance lift situation of hard flank in order to improve the performance of air cushion vehicle.

The purpose of this utility model is: the regulating mechanism that is used to control air cushion vehicle hard flank that a kind of simple in structure, full response effect that can realize air cushion vehicle is provided, so that the hard flank can be with the change of landform, as the ground that rises and falls or water surface wave and bob, nationality is to avoid the friction with the interface.

The utility model is achieved in that the regulating mechanism of control air cushion vehicle hard flank is by an arc-shaped rail and is arranged on the rolling body that rolls in the arc-shaped rail and constitutes.

The utility model is simple in structure, easy to adjust, utilizes rolling body with the fluctuating and move around of hard flank, and when the hard flank is floated with the interface, keeps its clockwise moment and anticlockwise moment about equally, has realized the full response effect of air cushion vehicle.

Below in conjunction with embodiment the utility model is described in detail:

Fig. 1 faces the structural representation sketch for what the utility model regulating mechanism was used for air cushion vehicle;

Fig. 2 for the rolling body of the utility model regulating mechanism with the mobile view of the come-up of flank;

Fig. 3 faces the structural representation sketch for the embodiment that the utility model regulating mechanism is used for air cushion vehicle;

Fig. 4 is used for the embodiment side-looking structural representation sketch of air cushion vehicle for the utility model regulating mechanism;

Structure when Fig. 5 is subjected to the alluvion state when being used to regulate the air cushion vehicle flank for the utility model regulating mechanism is cutd open and is shown sketch.

The regulating mechanism of control air cushion vehicle hard flank is to be made of an arc-shaped rail 4 and the rolling bodys 5 that are arranged on rolling in the arc-shaped rail 4, this regulating mechanism floats with hard flank 2, rolling regulating control by described rolling body, make the hard flank 2 of hull 1 both sides can be with the change of landform, as the ground that rises and falls or water surface wave 16 (as shown in Figure 5) and bob, nationality is to avoid the friction with the interface, realize the full response effect of air cushion vehicle, the air stream outlet gap that is hard flank 2 and interface 6 keeps an about fixed constant, when just the hard flank floats with the interface, its clockwise moment and anticlockwise moment are about equally, and flank is in case upwards rotate, it is increasing that its anticlockwise moment then can become, clockwise moment is then roughly constant, this is to increase because sine θ is increase with the θ angle, in order to keep the roughly balance of two moments, need to reduce the length of the arm of force, regulating mechanism of the present utility model can make the adjusting of hard flank 2 oversimplify, the anticlockwise moment size of utilizing moving of described rolling body 5 centers of gravity to change hard flank 2, just to keep two, the roughly balance of counter torque has realized the full response effect of air cushion vehicle.

Because of regulating mechanism together fluctuates with hard flank 2, described flank regulating mechanism can be arranged on the top of hard flank 2 separately (as Fig. 1, shown in Figure 2), the control agent that is regulating mechanism is provided with an arc-shaped rail 4, described arc-shaped rail 4 is provided with a rolling body 5, on track 4, to move around, consider the spacing problem of rolling body 5, rolling body 5 can be at control agent 15 (as Fig. 3, shown in Figure 4) inner by rolling back and forth in the circular arc passage 13 that arc-shaped rail 11 and last arc-shaped rail 10 constitute down, at this moment, the control agent 15 of regulating mechanism can form the circular arc body structure that there are a circular arc passage 13 and rolling body 5 in inside, when flank 2 rises, rolling body 5 moves to the inside, when flank 2 descends, rolling body 5 moves laterally, the air extractor duct gap that has guaranteed hard flank and interface still remains unchanged on the interface that rises and falls, for regulating mechanism is together fluctuated with hard flank 2, only need itself and hard flank 2 linked together and get final product, concrete mode can be that the top with control agent 15 links to each other with the hollow bushing 7 on hard flank 2 tops, and rolling body 5 can be spheroid or cylinder etc.

The hard flank 2 of the utility model control is positioned at the both sides of hull 1, the both sides of hard flank 2 respectively are provided with a side plate 9, in order to adapt with hard flank 2, the bottom of described hard flank 2 can be provided with a base plate 12, the top connecting bridge of hard flank 2 is a hollow bushing 7, and described hollow bushing 7 is socketed on the axle 3, so that hard flank 2 rotates up and down around axle 3 by bearing 8, described axle 3 is connected in hull 1 side, and 2 of adjacent hard flanks are provided with locating part 14.
