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

[0037] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0038] See also Figure 1 , and combined with Figure 2 and Figure 3 As shown, a wind-solar power generation multifunctional integrated street lamp of the present invention comprises a lamp pole 1, a solar power generation panel 2, an LED street lamp 3 and a spiral wind turbine 4, wherein the spiral wind turbine 4 is installed on the top of the lamp pole 1, that is, the spiral wind turbine 4 is driven by wind energy to generate electric energy to provide working voltage for the LED street lamp 3, wherein the lamp pole 1 of the present invention is hollow and has a cable passing therein, and is equipped with a 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] In order to explain the structure of the present invention in detail, two spiral wings 42 will be taken as an example below. When the two spiral wings 42 (such as the left spiral wing 42 and the right spiral wing 42) are installed on the shaft 41 through the connecting arm 47, since the connecting arm 47 is installed on the shaft 41 in a spiral staggered shape, after the left spiral wing 42 and the right spiral wing 42 are installed on the shaft 41, part of the cross-section is in an overlapping state. Moreover, the connecting arm 47 itself is a plate-like structure, so a spiral entrance is formed, and the structure is large outside and small inside. When the spiral entrance of the wind guide drum is introduced, it will act on the inner side of the spiral wing 42 to promote the spiral wing 42 to rotate rapidly. When the two spiral wings 42 act at the same time in relative directions, they can drive the rotor at the bottom to rotate rapidly to cut the magnetic flux lines generated by the coil to achieve its high-speed power generation. The same volume of spiral wings 42. The spiral space and pressure closure structure formed by the spiral wings 42 of the present invention can increase the power generation by 43.5%. For specific structure, please refer to Figure 3 and Figure 4 shown.

[0045] Please continue reading Figure 5 , Figure 6 and Figure 7 As shown, the spiral wing 42 of the present invention includes a plurality of wing plates 43, the wing plates 43 are arc-shaped, and a plurality of spaced ridges 44 are arranged on the inner edge surface thereof, the height of the ridges 44 gradually decreases from the free end of the wing plate 43 to the side of the wing plate 43 close to the shaft 41, the windward side of the ridges 44 is concave arc-shaped, the arc length of the wing plate 43 becomes longer along the length direction of the spiral wing 42, the two sides of the wing plate 43 are bent inwardly to form a connecting edge 45, the connecting edge 45 is provided with a countersunk hole 46, and adjacent wing plates 43 are connected to each other by bolts installed in the countersunk holes 46.

[0046] That is to say, when the wind acts on the spiral wing 42 formed by the wing plate 43 and drives the wing plate 43 to rotate, it first acts on the arc surface of the convex ridge 44. Due to the height variation and ups and downs of the convex ridge 44, the wind force is not only locked in the two spiral wings 42, but also forms an ups and downs vortex. Combined with the subsequent introduction of wind force, the driving force of the spiral wing 42 is enhanced, the wind speed is increased, and its power generation effect is enhanced. At the same time, the structural design of the convex ridge 44 can also effectively improve the strength of its wing plate 43. For details, please refer to Figure 7 shown.

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

[0048] The connection edge 45 design of the present invention can not only form a transverse support rib to improve the strength of the wing plate 43, but also form an enveloping design. Combined with the design of the sealing gasket, it can prevent air leakage from reducing the wind pressure and affecting its effect.

[0049] Furthermore, because adjacent wing plates 43 are connected via bolts installed in countersunk holes 46 and sealing gaskets are provided between adjacent wing plates 43, a sealed introduction space with a wide outside and a narrow inside is formed between the connecting arm 47, the outer edge surface of the shaft rod 41 and the spiral wing 42.

[0050] Therefore, when wind is introduced, due to the structure of the sealed introduction space being larger outside and smaller inside, combined with the sealing gasket between the wing plates 43, such a design can further increase the instantaneous pressure of the wind due to the instantaneous internal and external pressure difference, thereby further increasing the rotational power of the spiral wing 42.

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

[0052] The spiral wind turbine 4 is connected to the lamp pole 1 via a docking flange 8 .

[0053] The multifunctional integrated street lamp for wind and solar power generation of the present invention can realize two modes of wind power generation and solar power generation by installing a spiral wind turbine 4 on the top of the lamp pole 1 and combining it with a solar power generation panel 2, so as to generate electricity and charge the battery. The structure utilizes the hollow structure of the lamp pole 1, which can effectively reduce the overall floor space. At the same time, the spiral wind turbine 4 is adopted to improve the shape of the spiral wing 42, thereby improving its wind energy utilization rate, further improving its wind energy power generation effect, and improving its power generation efficiency.

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

[0055] (1) The footprint is small, similar to that of street lamps. The wind turbine is combined with photovoltaic panels to ensure stable power generation. While ensuring the power consumption of the equipment itself, the surplus power is connected to the grid to create economic benefits.
