Description

Fluid Kite Power Generation System

The present invention relates to a wind power generation device, and more particularly to a flow kite power generation system that utilizes a kite to generate electricity.

Kites are one of the options for generating electricity using wind power. Currently, most designs for generating electricity using kites use the ups and downs of kites when they fly, and use the ups and downs of kites to drive a generator set on the ground to generate electricity. However, there is currently no design that integrates a generator into a kite, so a new design that integrates a generator into a kite is needed.

The object of the present invention is to provide a flow kite power generation system that can overcome at least one disadvantage of the prior art.

The flow kite power generation system comprises a flow kite device and a power generation device. The flow kite device comprises a skeleton unit, a frame unit arranged on the skeleton unit, and a blade unit arranged between the skeleton unit and the frame unit. The power generation device is arranged on the frame unit.

The utility model is to innovatively integrate the flow kite device and the power generation device, and provide a design different from the prior art.

In the following description, similar or identical components will be denoted by the same reference numerals.

1 to 3 , an embodiment of the flow kite power generation system of the present invention comprises a flow kite device 1 and a power generation device 2 disposed on the flow kite device 1 .

The flow kite device 1 includes a skeleton unit 3, a frame unit 4 arranged on the skeleton unit 3, a kite unit 5 arranged between the skeleton unit 3 and the frame unit 4, a pivot unit 6 and a tail unit 7 pivotally connected to the skeleton unit 3, and two aileron units 8 respectively installed on the left and right sides of the skeleton unit 3.

The skeleton unit 3 includes a plurality of frame tubes 31 and a plurality of frame rods 32 connected to each other. The frame tubes 31 are arranged in a diamond shape. The frame rods 32 are arranged in a crosshair shape and connected between the connection of the frame tubes 31 and the periphery of the frame unit 4.

Two of the rack tubes 31 are used to install the hinge units 6. Each rack tube 31 for installing a respective hinge unit 6 is formed with two sockets 311 spaced apart from each other along the axial direction of the rack tube 31 as shown in FIG3. Each socket 311 extends along the arc direction of the rack tube 31 for about half a circle.

The frame unit 4 includes a frame 41 whose main part is rectangular, and a frame rod 42 disposed in the frame 41. The frame rod 42 separates an inner space 43 of the frame 41 into two installation areas 431 arranged on the left and right.

The kite unit 5 includes a plurality of kite bodies 51 stretched between the frame tubes 31, the frame rods 32 and the frame 41 of the frame unit 4, and a plurality of air bags 52 respectively arranged on the kite bodies 51. The kite bodies 51 cooperate to form the kite surface. Since the material and the stretching method of the kite bodies 51 are common knowledge, the description is omitted here. The air bags 52 can improve the floating ability of the first embodiment during flight. In addition, the air bags 52 located at the tip of the present embodiment can also reduce the wind resistance of the reverse wind.

The pivot unit 6 is disposed at a position (i.e., the head) of the skeleton unit 3 opposite to the tail unit 7, and includes a frame 60 connected to the frame 41 of the frame unit 4, an axle 61 extended leftward and rightward and installed on the frame 60, and two plates 62 pivotally connected to the axle 61 so as to pivot relative to the axle 61 and the skeleton unit 3.

The tail unit 7 includes a tail frame 71 pivotally connected to the frame unit 3 and capable of pivoting relative to the frame unit 3, and two tail pieces 72 arranged on the tail frame 71. The tail frame 71 has a roughly regular triangle shape and defines two right-angled triangle frame areas 73 arranged left and right. Each of the tail pieces 72 is arranged in a respective frame area 73. In other embodiments of the present invention, the tail pieces 72 can also be designed to be rotatable, and the buoyancy can be reduced by changing the area of the tail pieces 72 that bear the wind force, so that the first embodiment can be reduced in height due to the reduction of buoyancy.

Each of the aileron units 8 is mounted on a respective one of the frame tubes 31. Since the aileron units 8 have the same structure and only extend in different directions, in the following description, one of the aileron units 8 and the corresponding one of the frame tubes 31 will be used as a representative description.

The aileron unit 8 includes a pivot 81 (see FIG. 3 ) coaxially and fixedly inserted into the frame tube 31 of the frame unit 3, an aileron frame 82 which is sleeved on the pivot 81 and protrudes out of the frame tube 31 through the sockets 311, an aileron sheet 83 (see FIG. 1 ) stretched on the aileron frame 82, and an elastic component assembly 84 (see FIG. 3 ) assembled and connected between the pivot 81 and the aileron frame 82.

The aileron frame 82 includes two first rods 85 inserted into the pivot 81 and spaced apart from each other along the axial direction of the pivot 81 , and a second rod 86 connected between the first rods 85 (see FIG. 1 ).

Each of the first rod members 85 includes a sleeve rod portion 851 (see FIG. 3 ) that is annular and sleeved on the frame tube 31, and a main rod portion 852 (see FIG. 3 ) that is inserted into a respective one of the sockets 311 and protrudes from the sleeve rod portion 851 out of the frame tube 31. The aileron frame 82 can pivot relative to the pivot 81 by means of the sleeve rod portions 851 that are sleeved on the pivot 81, so that the aileron unit 8 can pivot relative to the frame unit 3.

The second rod 86 cooperates with the first rods 85 and the frame tube 31 to form a parallelogram.

The flap body 83 is disposed between the first rods 85 and the second rods 86 .

The elastic member assembly 84 includes two elastic members 841 (see FIG. 3 ) axially spaced from each other. Each of the elastic members 841 is a torsion spring inserted between the pivot 81 and the main rod portion 852 of the first rod 85. The elastic members 841 can cooperate to provide elastic force for the first rods 85 to pivot relative to the pivot 81.

The power generation device 2 includes two generator sets 21 disposed on the frame unit 4 and respectively located in the installation areas 431 of the frame inner space 43. Each of the generator sets 21 includes a rotating shaft 211 pivotally connected between the frame 41 and the frame rod 42 of the frame unit 4, and a plurality of blades 212 disposed on the rotating shaft 211 and capable of driving the rotating shaft 211 to rotate.

Referring to Figures 1, 3, and 4, the first embodiment is characterized in that the power generating device 2 is innovatively integrated with the flow kite device 1. In use, the power generating device 2 can be connected to a ship with a power storage device installed inside by a cable as shown in Figure 4, so that the wind power in the air can be converted into electricity and stored or used as the propulsion power of the ship. In addition to being used by the ship, the stored electricity can also be output when the ship is docked to supply the power demand on land.

The second feature of the first embodiment is that the pivot unit 6, the tail unit 7 and the aileron units 8 can allow the first embodiment to ascend and descend at any time within the range of wind force that the first embodiment can withstand. In addition, in other embodiments of the present invention, a hook can be further provided on the frame unit 3 to drive the present invention to take off through a drone or other buoyant vehicles (such as balloons).

Referring to FIG. 5 , a second embodiment of the flow kite power generation system of the present invention is similar to the first embodiment, except that each power generation device 2 further includes a bracket set 22 . The flow kite device 1 further includes a flow guide unit 9 extending downward from the bracket set 22 .

The bracket assembly 22 is provided at two opposite ends of the rotating shaft 211 of each generator set 21 , so that the generator sets 21 are more prominent on the kite surface of the flow kite device 1 .

The guide unit 9 includes an extension support assembly 91 extending radially outward from the bracket assembly 22 and radially protruding from the generator assembly 21, a guide assembly 92 protruding from an end of the extension support assembly 91 opposite to the rotation shafts 211 toward the blades 212, and a V-shaped turning support assembly 93 connected between the extension support assembly 91 and the guide assembly 92. The second embodiment is characterized in that the guide assembly 92 of the guide unit 9 can guide the forward wind to blow toward the blades 212.

Referring to FIG6 , a third embodiment of the flow kite power generation system of the present invention is similar to the first embodiment, except that: the skeleton unit 3 has an airplane-like appearance and a pointed head, so the arrangement of the frame tubes 31 and the racks 32 is different. There are two frame units 4. There are two pivot units 6, which are arranged on the left and right sides of the head of the skeleton unit 3. Each pivot unit 6 omits the frame 60 and is directly connected to the rack 32 by the shaft 61. The tail unit 7 is omitted (see FIG1 ). There are four aileron units 8, two of which are parallelogram-shaped as described above and are disposed at the tail of the skeleton unit 3, and the other two are rectangular and are disposed on the left and right sides of the skeleton unit 3. The power generation device 2 includes four generator sets 21. The generator sets 21 are arranged in groups of two in the left and right sides in respective frame units 4. Since the third embodiment integrates the power generation device 2 on the flow kite device 1 in the same manner as the first embodiment, a design different from the prior art is also provided.

In summary, the utility of the flow kite power generation system of the present invention lies in: innovatively integrating the flow kite device 1 and the power generation device 2, providing a design different from the prior art.

The above is only an embodiment of the present invention, and cannot be used to limit the scope of the patent application of the present invention. In addition, simple equivalent changes and modifications according to the scope of the patent application of the present invention and the patent specification should also be covered by the scope of the patent application of the present invention.
