Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the novel high-efficiency fluid kinetic energy capturing device includes a main shaft 1, at least two connecting rods 2, blades 3, a vertical position-limiting member 4, and a horizontal position-limiting member 5. The device can be used for wind power generation or tidal power generation, can capture the kinetic energy of fluid such as wind, water and the like and convert the kinetic energy into the rotational kinetic energy of the device, and reduces the resistance in the process of capturing the kinetic energy of the fluid.

The main shaft 1 is rotatably arranged, and a generator is driven to generate electricity through the rotation of the main shaft 1. For example, the lower end of the main shaft 1 may be connected to a bearing, so as to facilitate the rotation of the main shaft 1 around its central axis. The main shaft 1 is also provided with a gear which is coaxial with the main shaft 1 and is meshed with a gear on the generator, so that the rotary kinetic energy of the main shaft 1 is transmitted to the generator. The main axis 1 is arranged perpendicular to the fluid flow direction.

The connecting rods 2 are evenly arranged around the main shaft 1, and the connecting rods 2 extend from the main shaft 1 along a direction perpendicular to the main shaft 1. Specifically, one end of the connecting rod 2 is fixed to the upper end of the main shaft 1 and extends outward in a divergent manner. In some embodiments, the number of links 2 may be 2, 4, or 6. Preferably, the connecting rod 2 is cylindrical.

Each link 2 connects a blade 3, the blade 3 being configured to be able to be flipped around the link 2, the centre of gravity of the blade 3 being located below the flipping axis of the blade 3. For example, the blade 3 and the connecting rod 2 are connected by a bearing 6, and the bearing 6 and the connecting rod 2 are coaxially arranged. Specifically, a bearing seat may be fixed to the blade 3, the bearing 6 is disposed on the bearing seat, and the bearing 6 is fitted over the connecting rod 2.

A vertical stop 4 extends downwardly from the connecting rod 2 for providing a stopping force to the vane 3 in the direction of the fluid flow. For example, the embodiment shown in fig. 1 has two blades 3, named blade 31 and blade 32, respectively, the direction of arrow F being the direction of the fluid flow, the blade 31 rotating in the direction of the fluid flow and the blade 32 rotating against the direction of the fluid flow when the device is rotated about the main shaft 1. The blade 31 is a blade along the fluid flow direction, one surface of the blade is pushed by the fluid, the other surface of the blade is blocked by the vertical limiting piece 4 and is limited to overturn, then the fluid can push the blade 31 to rotate around the main shaft 1 along the fluid flow direction, and at the moment, the blade 31 is in a vertical state, so that the kinetic energy of the fluid is absorbed to the maximum extent. Meanwhile, as the blades 32 and the corresponding connecting rods 2 rotate around the main shaft 1 against the flow direction of the fluid, the blades 32 lose the restraint of the vertical limiting parts 4, and the blades 32 can rotate around the connecting rods 2 in the direction away from the corresponding vertical limiting parts 4 under the pushing of the fluid, so that the blades are pushed to be close to the horizontal by the fluid, the fluid acting area of the blades 32 is greatly reduced, the resistance is greatly reduced, the internal consumption is reduced, and the whole fluid kinetic energy utilization efficiency is improved. As the connecting rod 2 rotates, the relative angle of the fluid flow direction to the vane 32 changes, and since the center of gravity of the vane 3 is located below the tumble axis of the vane 3, the vane 32 gradually rotates downward by its gravity to be restored. When the blades 32 rotate around the main shaft 1 to be parallel to the fluid flow direction and continue to rotate, the blades 32 start to turn into blades in the fluid flow direction, and the blades 31 start to turn into blades against the fluid flow direction. The circulation is carried out, and through the cooperation work of the blades 3, the device realizes continuous work, receives fluid kinetic energy to the maximum extent, reduces resistance and improves the utilization efficiency of the fluid kinetic energy.

The horizontal limiting member 5 is connected to the connecting rod 2 and extends to one side of the connecting rod 2 for limiting the vane 3 against the flow direction of the fluid from continuing to turn over when the vane is turned to the horizontal state. Referring to fig. 2, in a top view of the novel high-efficiency fluid kinetic energy capturing device of the present disclosure, a plurality of horizontal stoppers 5 extend clockwise. In other embodiments, when the novel efficient fluid kinetic energy capturing device is viewed from above, the plurality of horizontal stoppers 5 may also extend counterclockwise. The vertical limiting member 4 and the horizontal limiting member 5 of the present disclosure together define a range of regions where the blade 3 is turned, for example, in the embodiment shown in fig. 1, the blade 3 can be turned from the vertical state to the horizontal state or from the horizontal state to the vertical state, that is, the blade 3 can be turned within a range of 90 °. At the site of power generation, the fluid conditions are sometimes complex, for example pulsating or random fluid may turn the blade 3 over 90 ° against the direction of the fluid flow, in which case the blade 3 loses its ability to function. The horizontal stop 5 serves to limit the turning angle of the blade 3 against the flow of the fluid to within 90 °. Preferably, the upper surface of the horizontal stop 5 is flush with the highest point of the connecting rod 2, which is beneficial to block the blade 3 in a horizontal state when the blade 3 against the fluid flow direction is subjected to pulsating fluid or random fluid, so as to facilitate the resetting of the blade 3.

The blades 3 may be flat with a uniform mass distribution, such as in the embodiment shown in fig. 1, but of course the blades 3 may also be streamlined with a non-uniform mass, such as in the embodiment shown in fig. 3, the streamlined surface being able to further reduce the resistance of the blades against the flow of the fluid. In some embodiments, the vertical stop 4 is in the shape of a frame, which is beneficial to reduce the resistance of the vertical stop 4. In some embodiments, the horizontal stopper 4 may have a plate shape or a frame shape.

The outstanding advantages of the novel high-efficiency fluid kinetic energy capturing device are embodied in the following aspects:

(2) when the device rotates, the resistance of fluid to the blades is reduced, the power generation efficiency is improved, and after the blades rotate by a certain angle, the blades can naturally reset and return to the right by virtue of gravity, so that the continuous operation of the device is realized;

(3) the horizontal limiting piece resists the disturbance of the pulsating fluid and the random fluid, so that the device is prevented from losing the working capacity due to the disturbance.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
