Abstract

The invention discloses a method and a device for providing a propulsive force to objects moving in water. A propeller for the objects moving in water of the prior art comprises a starch, a scull, a screw propeller, an injector, and the like. The invention uses one or more vanes as the propeller and arranges on the objects moving in water. The vane is mounted by using a hinge or a loose-leaf. The vane can be closed or opened. When the propeller moves back and forth under a driving force in water, the vane automatically closes or opens so as to propel the object to move forward. When the vane is opened, the object is driven by a big propulsive force. When the vane is closed, the object is driven by a small resistance. According to the principle, a swimming shoe is invented. People who cannot swim can have an ability to swim, walk and ramble in water if the shoes are worn. Besides, the invention can replace the widely used flipper and can be assembled on a small boat so as to replace the starch and the scull.

Description

A kind of method and device thereof that makes hydrogymnastic object obtain propulsive force

Technical field

The present invention relates to a kind of method and device thereof that makes hydrogymnastic object obtain propulsive force.More particularly, relate to a kind of new propulsion method, the device that several employing the method advance.For example a kind of bathing shoes, a kind of ship's propeller.

Background technology

At present people's utensil that adopts usually that swims in the water is a flippers, obtains thrust by moving up and down of both legs.Shortcoming is can't put on a spurt, and efficient is low, speed is slow.The present invention puts on special bathing shoes, it is characterized in that the propeller that one or more are made up of blade being installed at the sole of every footwear, the blade auto-closing was to reduce resistance when the people bent one's legs in water, blade opens automatically and adds high thrust when kicking one's legs, thus make the swimmer obtain forward than high thrust.

Can also replace slurry, big shield etc. with the propeller dress aboard ship.

Summary of the invention

Object in the water such as people or ship, at present great majority adopt flippers or draw slurry, scull or propelling such as screw.Shortcoming is to be difficult to realize that flippers efficient is too low with the screw manpower.

The present invention has overcome the deficiencies in the prior art, and a kind of method and device thereof that makes hydrogymnastic object obtain propulsive force is provided.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions.One or more blade is installed on the object, has just constituted a propeller.It is laminar that blade is, by metal or duroplasts or hard rubber or resin or sclerderm leather or the wooden one-tenth of bamboo; Be inner core perhaps with sheet metal or wire netting, outside plastic covering or rubber or resin; Perhaps make sheet material with duroplasts or hard rubber or resin, sheet material inside accompanies fiber; Perhaps above sheet material paste outside Polypropylence Sheet or flexible materials such as fiber cloth or rubberized fabric.

Angle of rake structure has 3 classes:

1, hinge type propeller

The hinge type propeller generally is made up of one or more blade, blade is divided into two kinds, a kind of less, be called fixed blade, it is fixed on propeller and is pushed on the object, and it does not produce thrust, another kind is bigger, be called the propelling blade, can produce propulsive force, above two kinds of blade appropriate combination are got up, be installed in jointly on the axle, shut at the two ends of axle, and some is on axle on one side of close axle for each blade, and blade can rotate in 90 degree scopes around axle, if have only one to advance blade, can in 180 degree scopes, rotate, constitute the hinge type propeller like this, see accompanying drawing 1, if do not use fixed blade, the two ends of axle can be prolonged, and be carved with screw thread, can be fixed on the support that is pushed into object during use.See accompanying drawing 2, accompanying drawing 3.

2, loose-leaf system propeller

The loose-leaf system propeller advances one side of blade that more than one hole is arranged, be pushed on the object (not necessarily circular to more than one ring should be arranged, also can be fan-shaped or triangle or other shapes), the borehole jack that advances blade is on corresponding ring, and blade can freely rotate in 90 degree or 180 degree scopes around ring.

3, flexibly jointed chain formula propeller

Flexibly jointed chain formula propeller advance blade can be one side or two each paste or fixedly one deck soft flexible fiber or fiber cloth or Polypropylence Sheet or rubberized fabric or leather, the flexible portion of above paste is fixed on glue or bolt cover plate is pushed on the object, staying one little to fix near the place of blade, be called the flexibly jointed chain line, blade can freely be rotated in 90 degree scopes along this line, see accompanying drawing 4, accompanying drawing 5.

For the blade of above three class formations, be limited on earth and freely rotate in much scopes, 90 to spend be optimum value, above some also can, just reduced service efficiency.If have only one to advance blade, also can in 180 degree scopes, freely rotate.

One or more propelling blade is installed in certain water is pushed on the object, rotate in 90 degree or 180 degree scopes on each one side that advances blade can lean around nearly object, object seesaws in certain external force effect lower edge direction of advance, advance the blade auto-closing when travelling forward, advance blade to open automatically when moving backward, thereby make object obtain the method for propulsive force forward.

Hinge type propeller or loose-leaf system propeller or flexibly jointed chain formula propeller are installed in the bottom of bathing shoes, when the people who wears bathing shoes advances the blade auto-closing when chest bends one's legs in water, advance blade to open automatically downwards when kicking one's legs, thereby make the people obtain forward propulsive force.

Hinge type propeller or loose-leaf system propeller or flexible articulated propeller are installed on one or a few axle of ship, and in the immersion water, when axle when the ship direction of advance travels forward, advance blade auto-closing in water, advance blade in water, to open automatically when moving backward, thereby make hull acquisition propulsive force forward.

The specific embodiment

Bathing shoes of the present invention is that a fixed head is installed on sole, and shape is consistent with sole.Perhaps sole itself is exactly a smooth on-deformable fixed head.Hinge type propeller or loose-leaf system propeller or flexibly jointed chain formula propeller are installed on the fixed head.General each blade can freely rotate in 90 degree scopes, if the number of degrees more greatly some also can, just reduced efficient.

Accompanying drawing 6 is that 2 angle of rake bathing shoeses of hinge type are installed.2 both sides that advance blade to be installed in sole respectively, each blade construction as shown in Figure 7.Limit by sole, blade is subjected to when closed to limit near the kick of rotating shaft, and blade can only rotate in the free outside to footwear in 90 degree scopes.Thereby swimmer's blade when kicking one's legs opens blade auto-closing when bending one's legs automatically.

If use in the many places of people such as swimming pool, to pedal other swimmers and cause personal injury for unlikely, blade can adopt not too hard plastics, uses flexibly jointed chain formula propeller.

The present invention generally adopts the hinge type propeller of all-metal blade as ship's propeller.Be installed in the afterbody of power transmission shaft, advance the blade auto-closing when power transmission shaft travels forward, open automatically when moving backward.
