[0036] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0037] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.

[0038] Please refer to Figure 1 and in combination with Figure 2 and Figure 3 As shown, a multifunctional integrated street lamp for wind and solar power generation according to the present invention includes a lamp post 1, a solar power generation panel 2, an LED street lamp 3, and a spiral wind turbine 4. Among them, the spiral wind turbine 4 is installed on the top of the lamp post 1, that is, the spiral wind turbine 4 is driven by wind energy to generate electric energy, providing a working voltage for the LED street lamp 3. Among them, the lamp post 1 of the present invention is hollow and is provided with a cable inside and is also provided with a storage battery.

[0039] The solar power generation panel 2 of the present invention is installed on the upper part of the lamp pole 1 to receive solar energy. After being processed by the inverter, the solar power generation panel 2 can not only charge the battery and be used as the working voltage for the LED street lamp 3 on rainy days, but also directly provide the working voltage for the LED street lamp 3.

[0040] Under the combined action of the solar panel 2, the battery and the spiral wind generator 4, the two natural resources of solar energy and wind power can be used to generate electricity, and the energy is stored in the battery to provide a working voltage for the LED street lamp 3, so that it can work in rainy or windless conditions. Moreover, the present invention adopts a spiral wind generator 4, which is installed on the top of the lamp pole 1, which occupies a small area and has a more beautiful and practical appearance.

[0041] Specifically, the cross-section of the lamp pole 1 of the present invention is an octave-deformed structure and the diameter gradually increases from bottom to top to increase the supporting force of the lamp pole 1. In addition, the lamp pole 1 has a built-in battery, and the solar power generation panel 2 and the spiral wind turbine 4 can continuously charge the battery.

[0042] It should be noted that the spiral wind turbine 4 of the present invention comprises a shaft 41 and a spiral wing 42. The spiral wing 42 is arc-shaped, and the cross-sectional width of the spiral wing 42 gradually widens along its height direction. Figure 2 As shown, a wrapping structure is formed, so that after the wind acts on the spiral wing 42, a vortex is formed inside the spiral wing 42 to drive the middle shaft 41 to rotate.

[0043] Among them, the spiral wings 42 of the present invention are in an even number, and the spiral wings 42 are connected to the shaft 41 through a connecting arm 47, and the spiral wings 42 on the opposite sides are symmetrically arranged with each other. After being arranged in this way, the wind force on both sides acts on the spiral wings 42 to form a torque, and because the spiral wings 42 are designed with a covering structure, the wind effect can be effectively improved when they act.

[0044] To illustrate the structure of the present invention in detail, two helical wings 42 will be taken as an example below. After the two helical wings 42 (such as the left helical wing 42 and the right helical wing 42) are installed on the shaft rod 41 through the connecting arm 47, since the connecting arm 47 is installed on the shaft rod 41 in a helical staggered manner, therefore, after the left helical wing 42 and the right helical wing 42 are installed on the shaft rod 41, part of the cross-section is in an overlapping state. Moreover, the connecting arm 47 itself has a plate-like structure, so a helical inlet is formed, and the structure is larger on the outside and smaller on the inside. When the wind is introduced through the helical inlet of the wind guide copper drum, it will act on the inner side surface of the helical wing 42 to push the helical wing 42 to rotate rapidly. When the two helical wings 42 act simultaneously in opposite directions, they can drive the rotor at the bottom to rotate rapidly to cut the magnetic induction lines generated by the coil, realizing its high-speed power generation. With the same volume of the helical wing 42, the helical space and pressure closing structure formed by the helical wing 42 of the present invention can increase the power generation by 43.5%. For the specific structure, please refer to Figure 3 and Figure 4 as shown

[0045] Please continue to refer to Figure 5 , Figure 6 and Figure 7 as shown. The helical wing 42 of the present invention includes a plurality of wing plates 43. The wing plates 43 are arc-shaped, and a plurality of convex ribs 44 are arranged at intervals on the inner edge surface thereof. The height of the convex ribs 44 gradually decreases from the free end of the wing plate 43 to the side of the wing plate 43 close to the shaft rod 41. The windward side of the convex ribs 44 is concave and arc-shaped. The arc length of the wing plate 43 becomes longer along the length direction of the helical wing 42. Both sides of the wing plate 43 are bent inward to form a connecting edge 45. A countersunk hole 46 is arranged on the connecting edge 45. Adjacent wing plates 43 are connected by bolts installed in the countersunk hole 46.

[0046] That is to say, when the wind acts on the helical wing 42 formed by the wing plate 43 and pushes the wing plate 43 to rotate, it first acts on the arc surface of the convex rib 44. Due to the height change of the convex rib 44, with high and low undulations, the wind force is not only locked inside the two helical wings 42, but also forms high and low undulating eddies, combined with the subsequent introduced wind force, enhancing the pushing force of the helical wing 42, increasing the wind speed, and enhancing its power generation effect. At the same time, the structural design of the convex rib 44 can also effectively improve the strength of the wing plate 43. For the specific details, please refer to Figure 7 as shown

[0047] It should be noted that the wing plate 43 of the present invention adopts an aluminum-magnesium alloy structure, which can reduce the weight of the wing plate 43, thereby reducing the resistance.

[0048] The design of the connecting edge 45 of the present invention can not only form a transverse support rib to improve the strength of the wing plate 43, but also form a surrounding design. Combined with the design of the sealing gasket, it can avoid air leakage and reduce the air pressure, affecting its effect.

[0049] Moreover, since the adjacent wing plates 43 are connected by bolts installed in the countersunk holes 46, and gaskets are provided between the adjacent wing plates 43, a sealed inlet space with a wider outer part and a narrower inner part is formed between the connecting arm 47 and the outer edge surfaces of the shaft rod 41 and the spiral wings 42.

[0050] Therefore, when the wind is introduced, due to the structure of the sealed inlet space with a larger outer part and a smaller inner part, combined with the gaskets between the wing plates 43, designed in this way, due to the instantaneous internal and external pressure difference, the instantaneous acting pressure of the wind can be further increased, and the rotational power of the spiral wings 42 can be further improved.

[0051] Furthermore, each wing plate 43 of the present invention is spirally arranged on the shaft rod 41 along the height direction of the shaft rod 41 through the connecting arm 47. The lamp post 1 of the present invention is also provided with a wireless charging station 6 and an LED advertising screen 7.

[0052] Among them, the spiral wind turbine 4 is connected to the lamp post 1 through a docking flange 8.

[0053] A multi-functional integrated street lamp for wind and solar power generation of the present invention can realize two power generation modes of wind power generation and solar power generation by installing a spiral wind turbine 4 on the top of the lamp post 1 and combining with the solar power generation panel 2, and generate electricity and charge the storage battery. This structure utilizes the hollow structure of the lamp post 1, which can effectively reduce the overall floor area. At the same time, by adopting the spiral wind turbine 4, the shape of the spiral wings 42 is improved, the wind energy utilization rate is increased, and the wind power generation effect and the power generation efficiency are further improved.

[0054] Compared with the prior art, a multi-functional integrated street lamp for wind and solar power generation of the present invention has the following advantages:

[0055] (1) Small floor area, similar to the floor area of a street lamp. By combining a micro wind turbine with a photovoltaic panel, the stability of power generation is ensured. While ensuring the power consumption of the equipment itself, the surplus electricity is grid-connected to create economic benefits.

[0056] (2) By adopting the spiral wind turbine 4, the requirements for wind direction and wind force are relatively low, the average wind energy conversion efficiency is high, the operation and maintenance cost is lower than that of traditional horizontal axis wind turbines, and spiral blades are adopted (small volume, beautiful appearance, recyclable, color variable).

[0057] (3) The equipment has various functions, and is equipped with security camera monitoring, LED billboards, wireless charging boards and sockets, etc. 5G micro base stations, vehicle charging piles, etc. can be added according to different needs.

[0058] Finally, the method of the present application is only a preferred implementation, and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
