[0023] The airflow conversion power generation device provided in this embodiment can be used in street lamps, and can also be used in any equipment that can realize airflow conversion power generation.

[0024] The airflow conversion power generation device includes a rod body 200 and a lamp body 100. The rod body 200 can be in various shapes, depending on specific needs. The lamp body 100 is arranged on the upper part of the rod body 200, and the lamp body 100 emits light to illuminate the road. A generator, a control panel and a battery are arranged inside the rod body 200. The generator, the battery and the lamp body 100 are electrically connected to the control panel respectively. The control panel serves as a control center to control the operation of the generator and the battery. The generator converts kinetic energy into electrical energy. The electrical energy generated by the generator is stored in the battery, and the battery provides electrical energy for the lamp body 100.

[0025] A rotating cylinder 201 that rotates around the axial direction of the rod body 200 is provided on the rod body 200, and the rotating cylinder 201 is connected to the generator through a transmission structure, so that the rotation of the rotating cylinder 201 is transmitted to the generator through the transmission structure, driving the generator to work and achieve the power generation effect; a plurality of blades 202 are convexly provided on the outer periphery of the rotating cylinder 201, and the plurality of blades 202 are arranged at intervals in the circumferential direction of the rotating cylinder 201; an epitaxial wafer 203 is provided at the outer end of the blade 202, and the epitaxial wafer 203 is arranged in a spiral along the axial direction of the rod body 200.

[0026] The airflow conversion power generation device provided above is installed on the side of the road. When a car is driving on the road, the traffic drives the airflow to move. The movement of the airflow drives the blades 202 and the epitaxial wafer 203, thereby driving the rotating cylinder 201 to rotate. The rotation of the rotating cylinder 201 is transmitted to the generator, driving the generator to work and generate electricity, storing electrical energy for the battery, achieving the effect of airflow conversion to electrical energy, providing electrical energy for the lamp body 100 to work, and saving energy and being environmentally friendly. The spiral setting of the epitaxial wafer 203 forms a spiral wind when the airflow blown to the epitaxial wafer 203 and the blades 202, which is convenient for driving the rotating cylinder 201 to rotate.

[0027] The blades 202 are arranged in a spiral shape along the axial direction of the rod body 200, and spiral in the same direction as the epitaxial wafer 203, so that the airflow can drive the blades 202 to rotate; the epitaxial wafer 203 includes a middle section connected to the outer end of the blade 202, an upper extension section extending to the top of the blade 202, and a lower extension section extending to the bottom of the blade 202, so that the epitaxial wafer 203 extends to the top and bottom of the blade 202 respectively, increasing the length direction, increasing the range of action of the airflow on the epitaxial wafer 203 and the blade 202, and facilitating the rotation of the rotating cylinder 201.

[0028] Extending upward or downward from the middle of the epitaxial wafer 203, the distance between the epitaxial wafer 203 and the periphery of the rod body 200 gradually decreases, so that the epitaxial wafer 203 is arranged in a wrapped shape from the middle upward or downward on the periphery of the rod body 200. In this way, when the airflow blows the epitaxial wafer 203, the airflow spirals between adjacent epitaxial wafers 203 along the spiral direction of the epitaxial wafer 203, and as the distance between the epitaxial wafer 203 and the periphery of the rod body 200 decreases, the spiral motion of the airflow becomes more intense, which is convenient for driving the rotation of the rotating cylinder 201.

[0029] The epitaxial wafer 203 is made of soft material, so that as the direction of the airflow changes, the epitaxial wafer 203 can be blown and deformed in time to be more suitable for the flow direction of the airflow.

[0030] The epitaxial wafer 203 has an outer surface that is arranged away from the outer periphery of the rod body 200 . The outer surface of the epitaxial wafer 203 is provided with grooves that extend along the length direction of the epitaxial wafer 203 and penetrate the end of the epitaxial wafer 203 .

[0031] When the airflow blows onto the epitaxial wafer 203, since the outer surface of the epitaxial wafer 203 is provided with grooves, the grooves will form a low-pressure area, and the side of the epitaxial wafer 203 blown by the airflow will form a high-pressure area. Therefore, not only does the airflow generate a force on the epitaxial wafer 203, but also due to the arrangement of high and low pressures, a driving force of pressure difference can be formed on the epitaxial wafer 203, which facilitates the rotation of the epitaxial wafer 203 and the blade 202.

[0032] Adjacent blades 202 enclose a wind-containing area; the middle section of the epitaxial wafer 203 has an inner surface facing the wind-containing area, and along the direction from the side of the middle section of the epitaxial wafer 203 to the outer end of the blade 202, the inner surface of the middle section of the epitaxial wafer 203 is inclined toward the periphery of the rod body 200.

[0033] In this way, the airflow blowing onto the epitaxial wafer 203 will enter the wind containing area along the inner surface of the middle section under the inclined guidance of the inner surface of the middle section, thereby preventing more airflow from blowing outside the wind containing area. When more airflow enters the wind containing area, the force acting on the blades 202 is greater, which makes it easier to push the blades 202 to drive the rotating cylinder 201 to rotate.

[0034] The inner surface of the middle section is provided with a plurality of air guide grooves, which are arranged at intervals along the axial direction of the rod body 200 and run through the side of the middle section. The air guide grooves can guide the airflow to enter the wind holding area between the blades 202.

[0035] The width of the air guide groove gradually decreases along the side of the middle section to the blade 202, so that the speed of the air flow entering the wind containing area along the air guide groove will increase, and the air flow will form a spiral motion in the wind containing area.

[0036] A wind direction sensor is provided on the epitaxial wafer 203, and a driving ring 400 is provided in the area surrounded by the upper extension sections of the multiple epitaxial wafers 203. The driving ring 400 is connected to the upper extension sections of the epitaxial wafers 203, and the inner surface of the driving ring 400 is provided with internal gear teeth; an auxiliary motor is provided in the rod body 200, and the auxiliary motor and the wind direction sensor are electrically connected to the control board respectively, and the auxiliary motor is connected to the driving gear 401. A notch is provided on the rod body 200, and the notch at the extension of the driving gear 401 meshes with the internal gear teeth.

[0037] In this way, when the airflow is too small, the wind direction sensor can sense the direction of the airflow, and the control panel controls the auxiliary motor to drive the driving gear 401 to rotate. The driving gear 401 engages with the internal gear teeth, thereby driving the epitaxial wafer 203 and the rotating cylinder 201 to rotate. The rotation direction is consistent with the direction of the airflow, providing original power and auxiliary power for the rotation of the rotating cylinder 201.

[0038] The blades 202 are made of a transparent material and are covered with a light energy conversion film. A metal ring is provided on the inner surface of the rotating cylinder 201 and is arranged around the outer circumference of the rod body 200. A metal contact is provided on the control board and the metal ring abuts against the metal contact to electrically connect the light energy conversion film to the control board.

[0039] In this way, not only wind energy but also solar energy can be used to generate electricity. Even when the rotating cylinder 201 is rotating, the metal ring and the metal contact piece are always in contact and conductive, ensuring that the light energy conversion film is always electrically connected to the control board.

[0040] 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.
