Abstract

The utility model relates to a water rudder arranged at a waterborne air vehicle. The water rudder consists of a rudder surface, a rotary shaft which is a hollow shaft and a control mechanism which is composed of a control rod and a swing arm. The rotary shaft passes through a fixed seat fixed on a land effect air vehicle or a hull of a waterborne airplane to be connected with the rudder surface. An upper end of the rotary shaft is connected with the control rod by the sewing arm; the rudder surface is composed of a plurality of bushing type hollow cavities which in turn narrow downwards; the upper end and the lower end of hollow cavities positioned medially are respectively sleeved with tally bushings positioned at the upper end and the lower end of a neighboring hollow cavity. The top hollow cavity has a fixed connection with the lower end of the rotary shaft; the bottom hollow cavity is equipped with a bottom plane and connected with one end of a steel rope which passes through the rudder surface and the hollow rotary shaft. The other end of the steel rope is connected with an operating handle arranged in a driver cab of the waterborne air vehicle. A rest spring is arranged in the hollow rotary shaft; the upper end of the rest spring ejects at a roof cover positioned at the upper end of the hollow rotary shaft; the lower end of the reset spring ejects at the bottom plane of the bottom hollow cavity. Because equipped with a folding structure, the utility model can avoid a problem of rotating on the spot and assure a safe service for the waterborne air vehicle.

Description

The deployable and collapsible water rudder

Technical field

The utility model relates to the water rudder on a kind of overwater flight device.

Background technology

The water rudder of existing ground effect vehicle or hydroairplane is stationary structure, like this they high speed surface slide and take off dried up before or at a high speed during water, can occur dangerous " changeing " phenomenon with beating, even can cause rollover, influence the safety of ground effect vehicle or hydroairplane.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and a kind of deployable and collapsible water rudder that can effectively improve ground effect vehicle or hydroairplane safety performance is provided.

Technical solution of the present utility model:

A kind of deployable and collapsible water rudder, it is by rudder face, rotating shaft and steering unit are formed, steering unit is by joystick; rocking arm constitutes; rotating shaft is passed the permanent seat that is fixed on ground effect vehicle or the seaplane hull and linked to each other with rudder face; the rotating shaft upper end links to each other with joystick by rocking arm; it is characterized in that rotating shaft is a hollow shaft; rudder face is received little sleeve-type cavity body from top to bottom successively and formed by a plurality of; on each cavity body of centre; the lower end is following with the adjacent vacant cavity respectively; the upper end socket that coincide; cavity body that it is gone up most and rotating shaft lower end are affixed; its cavity body under has the bottom surface; this next stage cavity body links to each other with cable wire one end; cable wire passes rudder face and hollow rotating shaft; its other end links to each other with operation folding and unfolding handle in ground effect vehicle or the hydroairplane operator's compartment; be provided with retracing spring in hollow rotating shaft, withstands on the spring on the top cover on the hollow rotating shaft, and its lower end is against on the bottom surface of the next stage cavity body of rudder face.

The utility model adopts the water rudder of folding extended structure, then when ground effect vehicle or seaplane take-off or during water, it can close in the ventral automatically, has avoided " changeing " phenomenon with beating, has guaranteed the safety of ground effect vehicle or hydroairplane.

The specific embodiment

Such as Fig. 1-3; Deployable and collapsible water rudder of the present utility model is by rudder face 1; Rotating shaft 2 and operating mechanism 3 form; Operating mechanism 3 is by control stick 4; Rocker arm 5 consists of; Rotating shaft 2 is passed the holder 6 that is fixed on ground effect vehicle or the seaplane hull and is linked to each other with rudder face 1; Rotating shaft 2 upper ends link to each other with control stick 4 by Rocker arm 5; Characteristics of the present utility model are; Rotating shaft 2 is hollow shaft; Rudder face 1 is received successively from top to bottom little telescopic cavity body 7 and is formed by a plurality of; Middle each cavity body 7 upper; The lower end is lower with the adjacent vacant cavity respectively; The upper end coincide and is socketed; Its cavity body that goes up most 7 is affixed with rotating shaft 2 lower ends; Its cavity body 7 under is with the bottom surface; This next stage cavity body 7 links to each other with cable wire 8 one ends; Cable wire 8 passes rudder face 1 and hollow rotating shaft 2, and its other end links to each other with operation folding and unfolding handle in ground effect vehicle or the seaplane driver's cabin, is provided with back-moving spring 9 in hollow rotating shaft 2; Spring 9 upper ends withstand on the top cover of hollow rotating shaft 2 upper ends, and its lower end is against on the bottom surface of rudder face 1 next stage cavity body 7.

In the utility model, the shape of rudder face 1 each cavity body 7 can be cylindrical shells such as rectangle, circle, trapezoidal, ellipse, and preferably the side is the swept-out cylindrical shell, their sockets that coincide successively.

When the utility model was packed up, as Fig. 4, by operation folding and unfolding handle, with cable wire 8 pull-ups, its drove the next stage cavity body 7 of rudder face 1 and overcomes the elastic force of retracing spring 9, successively each cavity body 7 is upwards packed up, and the receipts of finishing rudder face 1 are folded.Otherwise under retracing spring 9 restoring force effects, each cavity body 7 is decontroled naturally.

Claims
