[0042] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0044] See also Figure 1 In this embodiment, a power generation device 10 is provided, which can be used to generate electricity based on natural forces such as wind energy and solar energy. The power generation device 10 can improve the technical problem of low power generation efficiency caused by unstable breeze in the prior art.

[0045] In this embodiment, please refer to Figure 1 and Figure 2 The power generation equipment 10 includes a bracket 100, a thermal energy air inlet assembly 200, a fan 300 and a generator set 400. The thermal energy air inlet assembly 200 is connected to the bracket 100, and the thermal energy air inlet assembly 200 has a flow channel from bottom to top. The thermal energy air inlet assembly 200 is used to heat the gas in the flow channel when heated so that the gas in the flow channel expands and rises to form an airflow. When the airflow is formed in the flow channel, the airflow flows from bottom to top. The fan 300 is arranged at the top of the thermal energy air inlet assembly 200, and the fan 300 has a plurality of blades 310, at least one blade 310 is provided with an air inlet channel 311, the air inlet channel 311 and the flow channel, and the air inlet channel 311 forms a Laval nozzle-type first air outlet 312 at the outer end of the blade 310. The generator set 400 is connected to the bracket 100, and is used to be connected to the fan 300 to generate electricity when the fan 300 rotates. Among them, Figure 2 The arrow A in the middle indicates the air outlet direction of the first air outlet 312 .

[0046] It should be noted that, in the present embodiment, the air outlet direction of the first air outlet 312 is eccentrically arranged relative to the rotation center of the fan 300, so that when the air is discharged from the first air outlet 312, the reaction force formed by the air outlet of the first air outlet 312 can achieve a driving effect on the fan blade 310, thereby causing the fan 300 to rotate. In addition, by setting the first air outlet 312 as a Laval nozzle type, the wind pressure at the first air outlet 312 can be increased, thereby achieving the purpose of increasing the air outlet flow rate of the first air outlet 312, which is conducive to increasing the reaction force of the air outlet acting on the fan blade 310, thereby facilitating the rotation speed of the fan 300.

[0047] As described above, during the power generation process in a breeze environment, the power generation device 10 can absorb the thermal radiation of sunlight through the thermal energy air inlet assembly 200, so that the gas in the flow channel can expand and rise under the condition of heating, and a flowing and high-pressure airflow can be formed in the flow channel. Since the air inlet channel 311 in the fan blade 310 is connected to the flow channel, the high-pressure airflow can flow into the air inlet channel 311 and be led out from the first air outlet 312. Since the first air outlet 312 adopts a Laval nozzle setting, the wind pressure and flow rate of the outlet air can be further improved, forming a situation where the airflow is ejected at the first air outlet 312, and the reaction force of the ejected airflow can promote the rotation of the fan 300, which means that even in a breeze environment, the fan 300 can also be stably rotated through the thermal radiation of sunlight, thereby ensuring stable power generation. Based on this, the power generation device 10 can improve the technical problem of low power generation efficiency caused by unstable breeze in the prior art.

[0048] Optionally, in this embodiment, the fan 300 has at least three blades 310, and each blade 310 is provided with an air inlet channel 311, and the outer end of each blade 310 forms a first air outlet 312, so that the outer end of each blade 310 can be subjected to the reaction force of the wind, which can ensure that the force of each blade 310 is balanced and the fan 300 rotates stably. It should be understood that in other embodiments of the present application, the air inlet channel 311 can be provided on only some of the blades 310, and the first air outlet 312 can be formed on the outer ends of some of the blades 310.

[0049] It is worth noting that if the external environment is windy, the blades 310 of the fan 300 can be directly rotated by the wind, thereby achieving the purpose of wind power generation. When the external wind environment is a breeze, the heat energy air intake assembly 200 can efficiently supplement the wind power to the fan 300, thereby ensuring the stable operation of the fan 300.

[0050] In this embodiment, the heat energy air inlet assembly 200 includes a collection box 220 and a plurality of vacuum heat collection tubes 210; the collection box 220 is arranged on the top of the bracket 100, and the plurality of vacuum heat collection tubes 210 are arranged around the bracket 100; the plurality of vacuum heat collection tubes 210 are arranged from bottom to top, and the top of the vacuum heat collection tubes 210 is connected to the collection box 220, and the internal space of the collection box 220 and the internal channels of the plurality of vacuum heat collection tubes 210 jointly form a flow channel; the bottom of the vacuum heat collection tube 210 is provided with an air inlet 211; the vacuum heat collection tube 210 is used to heat the gas inside thereof when heated so that the gas expands and rises due to the heat to form an air flow. The air inlet channel 311 is connected to the internal space of the collection box 220.

[0051] Among them, the multiple vacuum heat collection tubes 210 are heated under the condition of solar radiation, so as to achieve the purpose of heating the airflow inside the vacuum heat collection tube 210. The airflow inside the vacuum heat collection tube 210 expands and rises due to the heat, and then forms an airflow. After the airflow in the vacuum heat collection tube 210 expands and rises, the air inlet 211 will continuously introduce air into the vacuum heat collection tube 210, so that the airflow can be continuously introduced into the collection box 220. In addition, when multiple vacuum heat collection tubes 210 introduce airflow into the collection box 220, the collection box 220 can accept the airflow introduced by multiple vacuum heat collection tubes 210 to achieve the purpose of pressure balance. After the airflow continuously enters the collection box 220, the air pressure in the collection box 220 continues to increase, and at the same time, the hot air is continuously squeezed into the air inlet channel 311 of the fan blade 310, so that a relatively high-pressure airflow can be formed in the air inlet channel 311, and then the high-pressure airflow is exported from the first air outlet 312, so that the fan 300 can be driven based on the reaction force of the air outlet.

[0052] It is worth noting that by providing a plurality of vacuum heat collection tubes 210, the total amount of airflow introduced into the collection box 220 can be increased, and the air pressure can be quickly increased, so that the fan 300 can be driven quickly. At the same time, it can also ensure that the airflow introduced into the collection box 220 and the air inlet channel 311 is sufficient, ensuring that the fan 300 rotates stably.

[0053] Optionally, in this embodiment, the plurality of vacuum heat collection tubes 210 are tilted. When the plurality of vacuum heat collection tubes 210 are tilted, the radiation receiving area of ​​the plurality of positive air heat collection tubes can be increased, thereby improving the heating efficiency of the airflow in the vacuum heat collection tubes 210.

[0054] It should be understood that in other embodiments of the present application, multiple vacuum heat collection tubes 210 may also be arranged vertically.

[0055] In addition, in this embodiment, the heat energy air inlet assembly 200 further includes a heat preservation layer 230, and the heat preservation layer 230 is wrapped around the outside of the plurality of vacuum heat collection tubes 210. Providing the heat preservation layer 230 outside the plurality of vacuum heat collection tubes 210 is conducive to increasing the temperature of the plurality of vacuum heat collection tubes 210, thereby facilitating heating the airflow in the vacuum heat collection tubes 210 and improving the heating efficiency.

[0056] It should be understood that in other embodiments, the thermal insulation layer 230 may also be omitted.

[0057] In an embodiment of the present application, a plurality of fan blades 310 are arranged along a horizontal circular path; the fan blades 310 are extended along a horizontal arc path, and the air outlet direction of the first air outlet 312 is tangent to the extension path of the fan blades 310. That is to say, in the present embodiment, the fan 300 is arranged in a horizontally rotating manner. The fan blades 310 have a vertical wind receiving surface, and generally, the wind receiving surface is a side that is recessed on both sides of the fan blades 310. In addition, making the air outlet direction of the first air outlet 312 tangent to the extension path of the fan blades 310 can, on the one hand, facilitate the overall arrangement of the air inlet channel 311, and on the other hand, can facilitate the reaction force of the air outlet of the first air outlet 312 acting on the fan blades 310 to drive the fan 300 to rotate.

[0058] It should be understood that in other embodiments, the fan 300 may also be arranged to rotate in a vertical plane.

[0059] In this embodiment, please refer to Figure 1 and Figure 3 The power generation device 10 further includes a wind collector 500; the wind collector 500 includes a main body 510, a plurality of wind shields 520 and a plurality of wind guide plates 530. The main body 510 is in a frustum shape, and the end of the main body 510 with a smaller cross-sectional area is connected to the top of the fan 300; the plurality of wind shields 520 are arranged at intervals on the outer periphery of the main body 510, and the plurality of wind shields 520 are arranged vertically, and a downward wind guide cavity 521 is formed between any two wind shields 520; the plurality of wind guide plates 530 are respectively arranged in the plurality of wind guide cavities 521; the wind guide plates 530 are arranged obliquely, and a second wind outlet 531 obliquely downward is formed at the bottom of the wind guide cavity 521, and the second wind outlet 531 is used to discharge wind toward the wind receiving surface of the fan blade 310.

[0060] When the wind in the external environment blows to the wind collector 500, the two adjacent wind shields 520 limit the airflow in the wind guide cavity 521 to prevent the wind from being lost. Then, based on the main body 510 with a larger upper part and a smaller lower part, the airflow is guided downward, so that the airflow can be guided downward. Then, based on the guiding effect of the wind guide plate 530, the airflow is blown to the wind receiving surface of the fan blade 310, so that the wind can be supplemented for the rotation of the fan 300, which can further ensure the stable rotation of the fan 300.

[0061] Among them, multiple wind shields 520 are arranged at equal intervals along the outer circumference of the main body 510. Based on this, no matter which direction the wind in the external environment is, the wind can be collected by the wind guide cavity 521, and then the airflow is guided to the fan 300 through the wind guide plate 530 to ensure the stable rotation of the fan 300.

[0062] Furthermore, in this embodiment, the second air outlet 531 is a Laval nozzle outlet. Setting the second air outlet 531 as a Laval nozzle can increase the air pressure and flow rate of the second air outlet 531, thereby increasing the wind strength added to the fan 300, thereby improving the stability of the fan 300.

[0063] In addition, in this embodiment, the power generation device 10 further includes a thin film photovoltaic panel 600, and the wind blade 310, the top of the wind collector 500, and the wind shield 520 are all provided with the thin film photovoltaic panel 600. Therefore, not only wind power generation can be performed, but also solar power generation can be performed based on the thin film photovoltaic panel 600. In the case of abundant sunlight, on the one hand, the heat radiation of sunlight can be used to heat and expand the airflow in the heat energy air inlet assembly 200, and on the other hand, the thin film photovoltaic panel 600 can be used to fully utilize solar energy to improve power generation efficiency.

[0064] Among them, the electricity generated by the thin-film photovoltaic panel 600 installed on the top of the wind collector 500 can be extracted through the conductive ring and the graphite electrode, and after being rectified together with the electricity generated by other thin-film photovoltaic panels 600, it is sent to the energy storage battery at the bottom of the generator set 400 for energy storage.

[0065] In addition, in this embodiment, the power generation device 10 further includes a lightning protection device 700, which is disposed on the top of the wind collector 500. The lightning protection device 700 may be a lightning rod, which can prevent the power generation device 10 from being damaged by lightning in thunderstorms, thereby improving the overall safety of the power generation device 10.

[0066] Based on the power generation device 10 provided above, this embodiment further provides a power system, which adopts the power generation device 10 mentioned above. The power system can also improve the technical problem of low power generation efficiency caused by unstable breeze in the prior art.

[0067] In summary, when the power generation equipment 10 is in a breeze environment and generates electricity, the thermal energy air inlet assembly 200 can absorb the thermal radiation of sunlight, so that the gas in the flow channel can expand and rise under the condition of heating, and a flowing and high-pressure airflow can be formed in the flow channel. Since the air inlet channel 311 in the fan blade 310 is connected to the flow channel, the high-pressure airflow can flow into the air inlet channel 311 and be led out from the first air outlet 312. Since the first air outlet 312 adopts a Laval nozzle setting, the wind pressure and flow rate of the outlet air can be further improved, forming a situation where the airflow is ejected at the first air outlet 312, and the reaction force of the ejected airflow can promote the rotation of the fan 300, which means that even in a breeze environment, the fan 300 can also be stably rotated through the thermal radiation of sunlight, thereby ensuring stable power generation. Based on this, the power generation equipment 10 can improve the technical problem of low power generation efficiency caused by unstable breeze in the prior art. Furthermore, the wind collector 500 in the power generation device 10 can also direct the wind to the fan 300 to supplement the wind force to the fan 300, further ensuring the stable rotation of the fan 300 in a breeze environment, and can stably generate electricity, which is conducive to improving the power generation efficiency. In addition, in the power generation device 10, when it is in a windy environment, the rotation of the fan 300 can be directly achieved by wind power, so as to generate wind power; and when it is in a breeze environment, it can be based on the thermal energy air intake component 200 to generate stable power in a breeze environment; and a thin-film photovoltaic panel 600 is also set to generate solar power. In other words, the power generation device 10 has the functions of wind power generation, single breeze power generation and solar power generation at the same time, which can not only adapt to a variety of different environments, but also improve the power generation efficiency.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
