Problems solved by technology
The disadvantages are: 1. The application is too narrow
2. There are air holes on the frame, so the resistance is high and the efficiency is low when flapping forward or upward. 3. Even in the optimal solution, there are still many problems: the movable leaf is made of elastic deformable material, the thrust is small, and the lifting thrust is limited; The swing angle of the movable vane is less than 90 degrees, which makes it difficult to improve the efficiency; the use of sliding or rotating the movable vane to adjust the wind resistance makes the structure and control complicated and the forward resistance increases
In these schemes, it is difficult to balance efficiency and thrust, or the structure and control are complicated, and the application is too narrow

Embodiment Construction
[0010] In Fig. 3, it is an embodiment for underwater driving, the bracket (2) and the short rod limiter (3) are all stainless steel, and the movable leaf (1) is a stainless steel sheet and is distributed in pairs on the short rod limiter (3) ) on both sides, the movable leaf (1) is connected on the support (2) through rows of stainless steel filaments. One side of the movable leaf (1) connected to the bracket (2) is sharpened, and is used for automatically cutting off aquatic plants and the like stumbling on the movable leaf (1). The action process is: when the fluid driver moves forward from the rear end point of the reciprocating motion, the movable vane (1) is pushed by the fluid and arranged along the flow direction of the fluid. At this time, the resistance is the smallest. When the fluid driver moves forward to reciprocating motion When the front end point of the front end, the short rod limiter (3) keeps the movable vane (1) and the fluid flow direction to maintain a sm...

The invention relates to a liquid driver. Wherein, the movable leaf swinging in the angle limited by limiter is swing or rotationally connected to the back of support. When the driver moves forwards, the movable leaf will arrange along the direction of liquid, with minimum resistance, when the driver moves backwards, the angle between the movable leaf and the flow direction increases, to form dense baffle plate, and the resistance is maximum, or compressed by the driver, the liquid is injected backwards, to drive object forwards or flow the liquid. The invention can improve pushing force with high efficiency.
Description
Technical field: [0001] The invention relates to a device for driving an object in a fluid, which is a fluid driver that drives the fluid flow through a reciprocating motion to advance the object. Background technique: [0002] At present, the known methods for driving objects forward in the fluid include paddle type and paddle wheel drive, which have long been eliminated; commonly used is propeller type drive, including propellers used in air and propellers in water, When the rotation speed of the propeller exceeds a certain speed, its efficiency will be greatly reduced; the disadvantage of jet drive, such as jet propulsion and rocket engine, is high energy consumption and low efficiency; the electromagnetic drive developed by Japan is usually only used in conductive seawater Medium, and consumes a lot of power, and it is difficult to increase the thrust. And only be used for the flapping-wing type driving in the air, and driving force is little, another kind of improved f...
