Abstract
The present invention proposes a kind of new-type quant: the push-and-pull oar, and the push-and-pull oar is made of pull bar and expelling water device, and the expelling water device is a moving part, and when strutting, resistance is big, and it is also big to promote the moving power of shipping.When closing up, resistance is very little.Push-and-pull oar propelling thrust is big, and the space that accounts for during push-and-pull is less, can use more oar on the ship in same space.
Description
The present invention relates to a kind of oar of the usefulness of rowing the boat.
Oar of the prior art mainly is made of the narrow boards of band handle, and narrow boards is used for drying, promotes ship motion with its antagonistic force.This oar will be done the wheel transhipment and move, and action radius is bigger, and the strength of stirring water is less.
The present invention is exactly for solving the problems of the prior art, putting forward.
For simplicity, our oar that claims the present invention to propose is the push-and-pull oar.The push-and-pull oar mainly contains two and partly constitutes, as illustrate shown in Figure 1, and some is a rigid rod, we are referred to as pull bar (1), and another partly is a moving part, and we are referred to as expelling water device (2), the movable part of expelling water device and umbrella is similar, and the umbrella face of expelling water device can close up and open.When pull bar when the moving opposite direction of shipping pushes away, the expelling water device struts, and promotes water and makes ship motion.When pull bar retracted, the expelling water device closed up, thereby resistance is very little.
The umbrella face of expelling water device links to each other with slip ring (3) on being enclosed within pull bar by some strut bars.The expelling water device struts or when closing up, slip ring can slide along pull bar.Stop column (4) is used for limiting the scope that slip ring slides, thereby has limited the open size of expelling water device.
The push-and-pull oar can use separately, also can be connected with hull, will make the activity of push-and-pull oar during connection freely.
Push-and-pull oar propelling thrust is big, and action radius is little, can use more oar on same ship, is suitable for the ship of various artificial paddlings.
We deserve to be called first kind of embodiment that the scheme of stating is the push-and-pull oar.
Second kind of embodiment of push-and-pull oar as shown in Figure 2.When the moving direction of shipping promotes pull bar (1), the slip ring that strut bar connected (3) slides, and expelling water device (2) closes up, and resistance is very little.When the pulling pull bar, the expelling water device opens, and the resistance of water is big, thereby makes the power of ship motion also big.Stop column (4) is in order to limit the open size of expelling water device.
The third embodiment of push-and-pull oar is that above-mentioned two kinds of schemes are combined.In Fig. 2, the umbrella face of establishing the expelling water device is θ with the intersection on the plane of crossing pull bar and the angle of pull bar.θ＞90 ° in second kind of scheme.If in second kind of scheme, the push-and-pull oar is adjusted a little, can make θ＞90 °, that is to say 90 °＜θ＜180 °, this is with regard to the situation of first kind of embodiment of similar push-and-pull oar, as the dotted line among Fig. 2 partly shown in.
Claims (1)
1, a kind of oar of the usefulness of rowing the boat is characterized in that being made of pull bar (1) and expelling water device (2).
