Detailed Description
Before the present invention is described in detail, it should be noted that in the following description, like components are denoted by the same reference numerals.
Referring to fig. 2 and 3, a first embodiment of the vane device for flow force power generation according to the present invention includes a supporting unit 1, a rotating unit 2, a balancing unit 3 (see fig. 4), and a plurality of vane units 4.
The supporting unit 1 extends axially up and down and comprises a supporting section 11 supported on the ground and a top end section 12 connected with the supporting section 11 in a same body. The top end section 12 has a first engaging portion 13 recessed in the top surface thereof and located on the axis of the supporting unit 1, and the first engaging portion 13 is a conical recess with an inner diameter gradually decreasing downward.
The rotating unit 2 is coaxially sleeved outside the supporting unit 1 and can rotate in a rotating direction 5 relative to the supporting unit 1. The rotating unit 2 includes a top cover 21 rotatably coaxially assembled above the supporting unit 1, and a sleeve 22 extending downward from the top cover 21 and radially and alternately sleeved outside the supporting unit 1. The top cover 21 has a cover 211 vertically spaced from the top end 12, and a second engaging portion 23 rotatably and coaxially coupled to the first engaging portion 13, wherein the second engaging portion 23 protrudes downward from the cover 211 and has a tapered outer diameter and is inserted into the first engaging portion 13. The sleeve 22 has a cylindrical body 221 surrounding the supporting unit 1, and two sets of assembling portions 222 connected to the outside of the cylindrical body 221 and spaced up and down for assembling the blade unit 4.
The balance unit 3 is disposed between the support unit 1 and the rotation unit 2, and includes a plurality of first magnets 31 connected to the periphery of the support unit 1, and a plurality of second magnets 32 connected to the top cover 21 and one side of the sleeve 22 facing the support unit 1. The first magnet 31 and the second magnet 32 are aligned with each other and have opposite poles, so that the sidewall of the supporting unit 1 and the sleeve 22 do not contact each other.
The vane units 4 are arranged at angular intervals to be radially distributed. Each vane unit 4 includes a vane 41 radially spaced from the rotating unit 2, and a boom 42 connected between the sleeve 22 and the vane 41. Each of the rod sets 42 has two rods 421 respectively mounted on the assembling portion 222 and extending radially to connect to the blade 41. The vane 41 has a first vane portion 411 and a second vane portion 412 extending in the up-down longitudinal direction, the first vane portion 411 has a fluid facing surface 413 extending in the up-down longitudinal direction and extending in the width direction along the radial direction of the support unit 1, and the second vane portion 412 is pointed in the rotation direction 5.
Taking wind power generation as an example, in the first embodiment, when the blade 41 is pushed by wind power to drive the rotating unit 2 to rotate relative to the supporting unit 1, because the rotating unit 2 and the supporting unit 1 only depend on the contact between the cone tips of the first nesting portion 13 and the second nesting portion 23 and the bottom of the cone groove, the friction between the two is reduced, and the repulsive force generated by the first magnet 31 and the second magnet 32 prevents the rotating unit 2 from tilting left and right, so that the rotating unit 2 rotates relative to the supporting unit 1 more smoothly. Taking the blade unit 4 shown in fig. 3 as an example, the fluid-facing surface 413 of the left blade 41 has a large wind-receiving area, and the second blade portion 412 of the right blade 41 projects in the rotation direction, so as to effectively reduce wind resistance. The cooperation between the first blade portion 411 and the second blade portion 412 more efficiently drives the rotation unit 2 to rotate.
Referring to fig. 4, a second embodiment of the vane device for flow power generation of the present invention is different from the first embodiment in that: the top cover 21 and the supporting unit 1.
The end surface of the top end section 12 is concavely provided with a containing groove 120 for containing the lubricating oil 6, and is provided with a groove bottom surface 121 for defining the bottom edge of the containing groove 120, and the first engaging part 13 is a conical groove concavely arranged on the groove bottom surface 121. The top cover 21 has a cover 211 spaced above the supporting unit 1, a protrusion 212 protruding downward from the bottom of the cover 211 and inserted into the receiving slot 120, and a second engaging portion 23 protruding downward from the bottom of the protrusion 212 and having a conical shape.
The protruding portion 212 is inserted into the receiving groove 120, but the protruding portion and the receiving groove are supported by the first engaging portion 13 and the second engaging portion 23 to be not in contact with each other, and a space for receiving lubricant is maintained. Besides the lubricant can be contained in the containing groove 120, the protrusion 212 can limit the tilting angle when the rotating unit 2 is tilted by a large external force, so as to prevent the sleeve 22 from colliding with the supporting unit 1.
Referring to fig. 5, a third embodiment of the vane device for flow power generation of the present invention is different from the second embodiment in that: the structure of the receiving groove 120 and the bump portion 212.
The end face of the top end section 12 is recessed with the receiving groove 120, and further has a positioning post 122 protruding upward from the groove bottom 121 and located at the axis thereof. The first engaging portion 13 is recessed on the top surface of the positioning pillar 122. The bottom surface of the protruding portion 212 is recessed with a positioning groove 213 for the positioning pillar 122 to insert into, and has a positioning groove surface 214 defining the top edge of the positioning groove 213. The second engaging portion 23 protrudes downward from the positioning groove surface 214 and is rotatably connected to the first engaging portion 13. The accommodating groove 120 and the positioning groove 213 can accommodate the lubricant 6, and the positioning column 122 and the positioning groove 213 can make the rotating unit 2 and the supporting unit 1 more difficult to tilt and rotate.
It should be particularly noted that, in all the above embodiments, the structures of the convex columns and the concave grooves of the first engaging portion 13 and the second engaging portion 23 can be exchanged, so that the purpose of rotating the rotating unit 2 relative to the supporting unit 1 can be achieved in the use, and the two portions are not limited to be conical or semi-spherical, so that the first engaging portion 13 and the second engaging portion 23 can contact each other in a smaller area and achieve the effect of rotating.
In summary, the blade device for hydrodynamic power generation of the present invention has the following effects: the rotating unit 2 and the supporting unit 1 are supported and connected by the first engaging portion 13 and the second engaging portion 23, and the repulsive force generated by the balancing unit 3 prevents the sleeve 22 from tilting left and right and generating friction with the supporting unit 1, so that the rotating unit 2 can smoothly rotate relative to the supporting unit 1 without a bearing or other auxiliary components. The power generation efficiency can be improved by applying the power generation device, and the maintenance requirement is reduced. Therefore, the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
