In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, an embodiment of the present invention provides a breeze power generation tree apparatus including a trunk portion 10, a plurality of branch portions 20 connected to the trunk portion 10, and a power generation unit 30 mounted on each branch portion 20, each power generation unit 30 including a generator and a fan blade 300 rotatably mounted on the generator. The fan blade 300 is preferably vertically disposed to minimize wear on the bearings during rotation of the blade.
The breeze power generation tree device can be applied to various open fields, such as squares, roofs and the like. The field is free of barriers for shielding wind direction, and wind energy collection is facilitated. The breeze power generation tree device can be installed like a lamp pole, can be used as a landscape and can also generate power, the main part 10 and the branch part 20 of the breeze power generation tree device can be provided with equipment such as a camera, a street lamp, a broadcast and a 5G transmitting base station according to needs, and the electric energy generated by the fan blade 300 can directly supply power for the electric equipment on the tree.
As shown in fig. 2, the fan blade 300 of the present embodiment mainly includes a base 1 and two arc-shaped fan blades 2 fixed on the base 1, each fan blade 2 includes an inner end close to the center of the base 1 and an outer end extending radially toward the base 1, inner surfaces of the inner ends of the two fan blades 2 face each other and are arranged at intervals, orientations of inner surfaces of the outer ends of the two fan blades 2 are opposite, and the two fan blades 2 enclose an S-shaped airflow channel. The radius of curvature of the outer end of the fan blade 2 is larger than that of the inner end of the fan blade 2, so that the fan blade 2 is in an outward-expanding opening shape. More preferably, the radius of curvature of the fan blade 2 becomes gradually larger from the rotational center of the fan blade 300 toward the periphery, so as to better collect wind energy.
As shown in fig. 3, since the outer end of each fan blade 2 of the fan blade 300 extends outward, and the inner ends of the two fan blades 2 have opposite portions, when the fan blade 300 is mounted on a generator, it can rotate freely under the action of breeze, i.e. wind enters from the inner surface of the outer end of the fan blade 2 opposite to the incoming wind direction, and flows out from the inner surface of the outer end of the other fan blade 2 after passing through the S-shaped airflow channel surrounded by the fan blades 2, the fan blade 300 can rotate rapidly under the action of the airflow, and even if the wind direction changes, one of the two fan blades 2 always faces or partially faces the incoming wind direction, therefore, the fan blade 300 can ensure stable rotation in various wind directions, so as to generate continuous and stable current on the generator, and can be transmitted to the electrical equipment for power supply by connecting the output line of the generator.
The two fan blades 2 are preferably rotationally symmetrical in this embodiment. It is understood that in other embodiments, the number of the fan blades 2 may be more, for example, 3, 4, 5, etc., and this embodiment is not limited, and it is preferable that the intervals between the fan blades 2 in the rotation direction are the same to achieve a stable rotation process.
An energy storage unit, such as a lithium battery, may be further disposed in the breeze power generation tree device for storing electric energy generated by the generator. The fan blade 300 can be easily driven by only two stages of breeze, and according to estimation, one breeze tree generator can be installed with about 5KW, namely, the electricity can be generated at about 5 degrees per hour. A small lithium battery is arranged below the fan to store energy, so that redundant electricity can be stored at ordinary times, and when no wind exists, the energy storage unit can supply power to equipment (such as a camera, a street lamp, a broadcast and a 5G transmitting base station) on a wind tree.
As shown in fig. 4, the fan blade 300 further has a plurality of reinforcing ribs 3, the reinforcing ribs 3 are protruded on the inner surface of the fan blade 2, and are arranged at intervals along the height direction of the fan blade 2, so that the overall strength of the fan blade 2 can be enhanced, and the stress characteristics thereof can be improved. Fan blade 300 can also have structure post 4, and on base 1 was vertically located to structure post 4, two flabellum 2 then can be fixed simultaneously on structure post 4, further strengthened flabellum 2's fixed reliability.

Therefore, the reinforcing rib plates 3 can be used as an air duct to distribute wind power, and the two fan blades can be connected around the middle structural column to extend in the circumferential direction, so that the integral structural strength is ensured. The fan blades 2, the strong rib plates 3, the structural columns 4 and the base 1 are preferably integrally formed, so that the stress and the mechanism strength of the blades can be increased, and the wind torque and the safety are improved.
As shown in fig. 5, the fan blade of the present embodiment further includes a cap 5, and the cap 5 covers the top ends of the two fan blades 2 at the same time, and can be used as a fixing structure for the top of the fan blades 2, and can also block part of the wind from leaking from the top of the fan blades 2. In other embodiments, the cap 5 may be omitted. In addition, the bottom of the inner end of the fan blade 2 is provided with a notch part 2a for air flow to pass through, and the notch part can be used as an air flow outlet, so that noise caused by air flow is reduced.
The energy storage unit can also be connected with the power generation unit 30 and the solar panel simultaneously, the electric energy generated by the power generation unit 30 and the solar panel can be stored simultaneously, the power generation unit 30 can provide electric energy for the control equipment of the solar panel, and the power generation unit and the control equipment can share the inverter to realize wind-solar cooperative work.
