[0032] See also Figure 1 The present embodiment provides a wind wheel structure 20, including a wind wheel assembly 210, wherein the wind wheel assembly 210 includes a transverse support 211 and a plurality of, for example, at least three, blade units 212 symmetrically arranged around the center of a rotating axis, wherein each of the blade units 212 includes: a first blade 2121; a second blade 2122, wherein the first blade 2121 and the second blade 2122 are both connected to the transverse support 211 to form a closed end, and the first blade 2121 and the second blade 2122 are inclined to form an angle, and the opposite side of the closed end (i.e., the end side of the transverse support rod 211) has a first opening; and a side baffle 2123, wherein the side baffle is arranged at an edge between the first blade 2121 and the second blade 2122 and is connected to the first blade 2121 and the second blade 2122, and the opposite side of the side baffle 2123 has a second opening.

[0033] In a preferred embodiment, each blade unit 212 is composed of two substantially square first blades 2121 and second blades 2122, which open outward from the horizontal support rod 211 at an angle. The side baffle 2123 is formed into a shape that bends outward, thereby forming an angle for wind. In a preferred embodiment, the horizontal support rod 211 is in a cross shape, thereby forming four horizontal support rods 211, and each horizontal support rod 211 is provided with a blade unit 212. It can be but not limited to a plurality of blade units distributed symmetrically around the center, such as two, three, five, six, etc., which can be selected and set according to different application scenarios.

[0034] The working principle of the wind wheel structure 20 provided in this embodiment is as follows:

[0035] The wind wheel structure 20 provided in this embodiment has a blade unit 212, wherein the first blade 2121 and the second blade 2122 are respectively connected to the cross bracket 211, and the first blade 2121 and the second blade 2122 form a closed end at the cross bracket 211, and the first blade 2121 and the second blade 2122 are inclinedly arranged so that the first blade 2121 and the second blade 2122 form an angle, and the opposite side of the closed end has a first opening, and at the same time, since a side baffle 2123 is arranged at the edge of the first blade 2121 and the second blade 2122, and the opposite side of the side baffle 2123 has a second opening, the first blade 2121, The second blade 2122 and the side baffle 2123 form a triangular cavity, and the first opening and the second opening are connected. External wind can blow into the triangular cavity through the first opening and be discharged from the second opening to drive the entire blade unit 212 and the cross bracket 211 to rotate, thereby realizing wind power generation. When the blade unit 212 rotates, the wind sweeping surface is increased (the cross-section of the wind sweeping surface formed in this embodiment is rectangular), thereby improving the wind power generation efficiency. Furthermore, since the wind wheel assembly 210 includes two or more blade units 212, wind from multiple different directions can be used to drive multiple blade units 212 to rotate at the same time, thereby further improving the wind power generation efficiency.

[0036] The beneficial effects of the wind wheel structure 20 provided in this embodiment are at least:

[0037] The wind wheel structure 20 provided in this embodiment is achieved by arranging the first blade 2121 and the second blade 2122 at an angle, with one end forming a closed end, and the opposite side of the closed end having a first opening, and a side baffle 2123 is arranged at the edge of the first blade 2121 and the second blade 2122, and the opposite side of the side baffle 2123 having a second opening, so that the first blade 2121, the second blade 2122, and the side baffle 2123 form a triangular cavity, and the first opening and the second opening are connected, with a simple structure and low cost. External wind enters the triangular cavity through the first opening and is discharged through the second opening to drive the blade unit 212 and the cross bracket 211 to rotate, thereby realizing wind power generation, increasing the swept wind area, and improving the wind power generation efficiency. In addition, since the wind wheel assembly 210 includes at least two blade units 212, wind from multiple different directions can be driven to rotate multiple blade units 212 at the same time, further improving the wind power generation efficiency. The power generation device 100 of the wind wheel structure 20 provided in this embodiment can be used as a street lamp, a pavilion, a parasol, a sentry box, a sentry box, etc.

[0038] In a preferred embodiment, please continue to refer to Figure 1The side baffle 2123 has a convex portion 21231, and the convex portion 21231 protrudes outward toward a side away from the second opening.

[0039] Since a protrusion 21231 is provided on the side baffle 2123, and the protrusion 21231 protrudes outward toward the side away from the second opening, that is, the protrusion 21231 protrudes outward toward the side away from the triangular cavity, when the triangular cavity is driven by external wind force to rotate the entire blade unit 212, the protrusion 21231 can reduce the resistance to the rotation of the blade unit 212, thereby improving the wind energy generation efficiency.

[0040] Optionally, the protrusion 21231 is located in the middle of the side baffle 2123 .

[0041] Optionally, the side baffle 2123 includes a first side baffle and a second side baffle, one end of the first side baffle is connected to the first blade 2121, one end of the second side baffle is connected to the second blade 2122, and the other end of the first side baffle is connected to the other end of the second side baffle to form the convex portion 21231. Optionally, the convex portion 21231 is in an outward convex angle shape. Optionally, the convex portion 21231 is in an outward convex arc shape.

[0042] In a preferred embodiment, the angle range between the first blade 2121 and the horizontal plane where the horizontal bracket 211 is located is 0° to 45°, and the angle range between the second blade 2122 and the horizontal plane where the horizontal bracket 211 is located is 0° to 45°. That is, the angle range between the first blade 2121 and the second blade 2122 is 0° to 90°. Under the action of wind, the angle range between the first blade 2121 and the second blade 2122 and the horizontal bracket 211 is set to 0° to 45°, and the angle is increased, which can increase the wind sweeping area, thereby improving the wind power generation efficiency.

[0043] Optionally, the angle between the first blade 2121 and the cross bracket 211 is 15° to 35°, and the angle between the second blade 2122 and the cross bracket 211 is 15° to 35°.

[0044] Optionally, the angle between the first blade 2121 and the cross bracket 211 is 30°, and the angle between the second blade 2122 and the cross bracket 211 is 30°, so that the formed triangular cavity is an equilateral triangular cavity.

[0045] It should be understood that the angle values ​​formed by the first blade 2121 and the cross bracket 211, and the angle values ​​formed by the second blade 2122 and the cross bracket 211 are not limited to the above values, and can also be other values, which are not limited here.

[0046] Optionally, the edge of the second blade 2122 at the second opening is toothed, so that the wind entering from the first opening can flow out of the triangular cavity evenly from the second opening, so that the blade unit 212 is pushed to rotate more smoothly.

[0047] In a preferred embodiment, please continue to refer to Figure 1 , the wind wheel assembly 210 includes four blade units 212, the cross bracket 211 is in a cross shape, and each support arm 2111 included in the cross bracket 211 is provided with a blade unit 212, and the alternate blade units 212 are centrally symmetrical. Since the cross bracket 211 is in a cross shape, that is, the cross bracket 211 includes four support arms 2111, and the four blade units 212 are respectively provided on the four support arms 2111, the four blade units 212 are also arranged in a cross shape, and the alternate blade units 212 are centrally symmetrical, so that the four blade units 212 receive wind from different directions respectively, that is, the entire wind wheel structure 20 can receive wind from four directions, thereby improving the efficiency of wind power generation.

[0048] In a preferred embodiment, see Figure 1 A support column 2128 with a wing-shaped cross section is further provided between the first blade 2121 and the second blade 2122 , and the support column 2128 is located on the opposite side of the side baffle 2123 .

[0049] The support column 2128, the first blade 2121, the second blade 2122 and the side baffle 2123 together form a stable triangular cavity structure. And because the cross section of the support column 2128 is wing-shaped, the four wing-shaped support columns 2128 of the four triangular cavities form another H-shaped four lift-type wind blades in the overall wind wheel structure 20 (in the relative movement between the incoming wind and the wind wheel structure, the wing-shaped support column 2128 obtains resistance and lift, and a pressure difference is generated on the two sides of the wing-shaped support column 2128 during the movement. The pressure difference is the main lift source of the wing-shaped support column 2128, and the lift enables the wind wheel structure to obtain effective torque), so that the wind wheel structure 20 in this embodiment becomes a combined wind wheel structure of resistance type and lift type, and in combination with the vertical shaft transmission structure 10 included in the wind wheel application device 100, the resistance type makes the wind wheel structure easy to start, and the lift type wind blade wheel can obtain a higher wind energy utilization rate. The wind wheel application device 100 can be a power generation device or any windmill device, and therefore, its size can be in various shapes and sizes.

[0050] In a preferred embodiment, see Figure 1 , Figure 2As shown, a first window 21221 is provided on the second blade 2122, and the first window 21221 is located at a corner formed by the first blade 2121, the second blade 2122 and the side baffle 2123. A first window sash plate 2125 is provided at the first window 21221, and the first window sash plate 2125 is connected to the second blade 2122 in an opening and closing manner.

[0051] When the wind reaches the set cut-out wind speed, the first window sash plate 2125 is pushed by the wind to open the first window 21221 outwards. The ventilation of the first window 21221 immediately reduces the thrust of the wind on the blade unit 212, and the rotation speed of the entire wind wheel structure 20 slows down accordingly. The first window sash plate 2125 gradually returns to its original position until the first window 21221 is closed, and the rotation speed of the wind wheel structure 20 returns to the normal range.

[0052] In a preferred embodiment, please continue to refer to Figure 1 , Figure 2 As shown, the first window sash plate 2125 is triangular in shape, and one side of the first window sash plate 2125 close to the first opening is connected to the second blade 2122 via a hinge, and the other two sides of the first window sash plate 2125 are connected to the second blade 2122 via an overspeed protection member 2127, respectively.

[0053] When external wind enters the triangular cavity from the first opening, the first window sash plate 2125 is pushed by the wind to open the first window 21221 outward, that is, the two sides connected to the first window sash plate 2125 and the second blade 2122 can be opened when the wind speed is high, and rotate around the second blade 2122 through the hinge to open the first window 21221. When the rotation speed of the wind wheel structure 20 slows down, the first window sash plate 2125 can return to its original position and close the first window 21221.

[0054] In a preferred embodiment, see Figure 1 , Figure 3 and Figure 4 , the wind wheel structure 20 further includes a drainage component 230, and the drainage component 230 is connected to the wind wheel component 210;

[0055] Among them, the drainage assembly 230 includes a drainage pipe 231, which is arranged along the tube body of the horizontal support rod 211. The drainage pipe 231 may be but is not limited to being provided with a strip water inlet 2311. The outer edge of the drainage pipe 231 is provided with a drainage outlet 2312, and the drainage outlet 2312 is provided on the side opposite to the rotation direction of the wind wheel structure 20.

[0056] Thus, rainwater can be collected on the wind wheel structure described in the present invention, and flow into the drain pipe 231 through the water inlet 2311 along the first blade 2121. The water in the drain pipe 231 flows to the drain outlet 2312 on the outer edge of the drain pipe 231. The drain outlet 2312 is arranged on the side opposite to the rotation direction of the wind wheel structure 20. The rainwater can generate a reaction force when discharged, thereby promoting the entire wind wheel structure 20 to rotate further, and then can drive the rotation of the applied wind wheel device, or generate electricity, so that in the absence of wind and light, the rotation of the wind wheel structure can be driven by discharging rainwater.

[0057] Optionally, the water inlet 2311 is a quarter drainage pipe surface, which is not only convenient for rainwater to enter, but also convenient for collecting rainwater so that rainwater will not overflow from the water inlet 2311.

[0058] Optionally, the impeller assembly includes a plurality of blade units 212, and each blade unit 212 is provided with a drain pipe 231 at the support arm 2111. When rainwater collected in the plurality of drain pipes 231 is discharged from the drain port 2312 at the same time, the wind wheel structure 20 is better driven to rotate.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
