[0042] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0043] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0044] Please refer to Figure 1 In the embodiment, a power generation device 10 is provided, which can be used for generating power based on wind energy, solar energy and other natural forces. 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 the embodiment, please refer to Figure 1 and Figure 2 The power generation device 10 includes a support 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 support 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 to make the gas in the flow channel expand and rise to form an air flow. In the case of forming an air flow in the flow channel, the air flow 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 fan blades 310. At least one fan blade 310 is provided with an air inlet passage 311, the air inlet passage 311 is communicated with the flow channel, and the air inlet passage 311 forms a first air outlet 312 in the form of a Laval nozzle at the outer end of the fan blade 310. The generator set 400 is connected to the support 100, and is used to be connected with the fan 300 to generate power when the fan 300 rotates. Among them, Figure 2 The A arrow in the figure indicates the air outlet direction of the first air outlet 312.

[0046] It should be noted that in the embodiment, the air outlet direction of the first air outlet 312 is arranged eccentrically relative to the rotation center of the fan 300. Thus, in the case of air outlet of the first air outlet 312, the reaction force formed by the air outlet of the first air outlet 312 can realize the driving effect of the fan blade 310, and further promote the rotation of the fan 300. In addition, the first air outlet 312 is arranged in the form of a Laval nozzle, which can increase the wind pressure at the first air outlet 312, and further can achieve the purpose of improving the air outlet flow rate of the first air outlet 312, which is beneficial to improve the reaction force of the air outlet acting on the fan blade 310, and further is beneficial to improve the rotation speed of the fan 300.

[0047] In the process that the power generation device 10 generates power in a breeze environment, the heat energy air intake assembly 200 can absorb the heat radiation of sunlight, so that the gas in the flow channel expands and rises under the condition of being heated, and a flowing and high-pressure air flow can be formed in the flow channel. Since the air intake channel 311 in the fan blade 310 is in communication with the flow channel, the high-pressure air flow can flow into the air intake channel 311 and be guided out from the first air outlet 312. Since the first air outlet 312 is arranged in the form of a Laval nozzle, the wind pressure and flow rate of the air outlet can be further improved, and the air flow sprayed at the first air outlet 312 can be formed, and the reaction force of the sprayed air flow can promote the rotation of the fan 300. Therefore, even in a breeze environment, the fan 300 can be stably rotated by the heat radiation of sunlight, thereby ensuring stable power generation. Based on this, the power generation device 10 can improve the technical problem that the power generation efficiency is not high due to unstable breeze in the prior art.

[0048] Optionally, in the embodiment, the fan 300 has at least three fan blades 310, and the air intake channel 311 is arranged in each fan blade 310, and the outer end of each fan blade 310 forms the first air outlet 312, so that the outer end of each fan blade 310 is subjected to the reaction force of the air outlet, and the balance of force of each fan blade 310 can be ensured, and the fan 300 can be stably rotated. It should be understood that in other embodiments of the present application, the air intake channel 311 can be arranged only on part of the fan blades 310, and the first air outlet 312 can be formed at the outer end of part of the fan blades 310.

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

[0050] In the embodiment, the heat energy air intake assembly 200 includes a collection box 220 and a plurality of vacuum heat collection tubes 210; the collection box 220 is arranged at the top of the support 100, and the plurality of vacuum heat collection tubes 210 are arranged around the support 100; the plurality of vacuum heat collection tubes 210 are arranged from bottom to top, and the top of the vacuum heat collection tube 210 is connected to the collection box 220, and the internal space of the collection box 220 and the internal passage of the plurality of vacuum heat collection tubes 210 together 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 in the inside thereof when heated to make the gas expand and rise to form an air flow. The air intake channel 311 is in communication with the internal space of the collection box 220.

[0051] The multiple vacuum heat collection tubes 210 are heated under the condition of solar radiation, so as to heat the air flow inside the vacuum heat collection tubes 210. The air flow inside the vacuum heat collection tubes 210 is heated and expanded to rise, and the air flow is formed. After the air flow in the vacuum heat collection tubes 210 is expanded and rises, the air inlet 211 continuously introduces air into the vacuum heat collection tubes 210, so as to continuously introduce the air flow into the collection box 220. In addition, under the condition that the multiple vacuum heat collection tubes 210 introduce the air flow into the collection box 220, the collection box 220 can receive the air flow introduced by the multiple vacuum heat collection tubes 210, so as to balance the pressure. After the air flow continuously enters the collection box 220, the air pressure in the collection box 220 continuously increases, and at the same time, the hot air is continuously pressed into the air inlet passage 311 of the fan blade 310, so as to form a high-pressure air flow in the air inlet passage 311. Then, the high-pressure air flow is introduced from the first air outlet 312, so as to drive the fan 300 based on the reaction force of the air outlet.

[0052] It should be noted that by arranging the multiple vacuum heat collection tubes 210, the total amount of the air flow introduced into the collection box 220 can be increased, so as to quickly increase the air pressure and drive the fan 300. At the same time, it can also ensure that the air flow introduced into the collection box 220 and the air inlet passage 311 is sufficient, so as to ensure that the fan 300 stably rotates.

[0053] Optionally, in the embodiment, the multiple vacuum heat collection tubes 210 are arranged obliquely. By arranging the multiple vacuum heat collection tubes 210 obliquely, the radiation area of the multiple vacuum heat collection tubes 210 can be increased, so as to improve the heating efficiency of the air flow in the vacuum heat collection tubes 210.

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

[0055] In addition, in the embodiment, the heat energy air inlet assembly 200 further comprises a heat preservation layer 230, and the heat preservation layer 230 is wrapped outside the multiple vacuum heat collection tubes 210. By arranging the heat preservation layer 230 outside the multiple vacuum heat collection tubes 210, the temperature of the multiple vacuum heat collection tubes 210 can be increased, so as to heat the air flow in the vacuum heat collection tubes 210 and improve the heating efficiency.

[0056] It should be understood that in other embodiments, the heat preservation layer 230 can also be omitted.

[0057] In the embodiment of the present application, the plurality of fan blades 310 are arranged along a horizontal circumferential path; the fan blades 310 extend along a horizontal arc-shaped 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, in the present embodiment, the fan 300 is arranged in a horizontal rotation manner. The fan blades 310 have a vertical wind-receiving surface, generally, the wind-receiving surface is the side of the fan blades 310 that is recessed on both sides. In addition, the air outlet direction of the first air outlet 312 is tangent to the extension path of the fan blades 310, which on the one hand can 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 can also be arranged in a vertical plane rotation manner.

[0059] In the present embodiment, please refer to Figure 1 and Figure 3 The power generation device 10 further comprises a wind collector 500; the wind collector 500 comprises a main body 510, a plurality of wind baffles 520, and a plurality of guide baffles 530. The main body 510 is in the shape of a truncated cone, 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 baffles 520 are arranged at intervals on the outer periphery of the main body 510, and are arranged vertically, and a downward guide air chamber 521 is formed between any two wind baffles 520; the plurality of guide baffles 530 are arranged in the plurality of guide air chambers 521 respectively; the guide baffles 530 are arranged obliquely, and form an obliquely downward second air outlet 531 at the bottom of the guide air chamber 521, which is used for air outlet towards the wind-receiving surface of the fan blades 310.

[0060] When the wind in the external environment blows to the wind collector 500, the airflow is restricted in the guide air chamber 521 by the adjacent two wind baffles 520, preventing the loss of wind power. Then, based on the main body 510 being larger at the top and smaller at the bottom, the airflow is guided downward, so that the airflow is guided downward. Then, based on the guiding action of the guide baffles 530, the airflow is blown to the wind-receiving surface of the fan blades 310, which can supplement the wind power for the rotation of the fan 300, and further ensure the stable rotation of the fan 300.

[0061] Among them, the plurality of wind baffles 520 are arranged at equal intervals along the outer circumference of the main body 510, based on which, no matter which direction the wind in the external environment is, the wind power can be collected through the guide air chamber 521, and then the airflow is guided to the fan 300 through the guide baffles 530, ensuring the stable rotation of the fan 300.

[0062] Further, in the embodiment, the second air outlet 531 is in the form of a Laval nozzle. The second air outlet 531 is provided in the form of a Laval nozzle, so as to improve the air pressure and flow rate of the second air outlet 531, and thus improve the wind power supplied to the fan 300, and improve the stability of the operation of the fan 300.

[0063] In addition, in the embodiment, the power generation device 10 further comprises a thin-film photovoltaic panel 600, and the thin-film photovoltaic panel 600 is arranged on the top of the fan blade 310 and the wind force collector 500 and the wind shield 520. Therefore, not only wind power generation can be achieved, but also solar power generation can be achieved based on the thin-film photovoltaic panel 600. In the case of sufficient sunlight, on the one hand, the heat radiation of sunlight can be used to heat and expand the airflow in the heat energy inlet assembly 200 to rise, and on the other hand, the thin-film photovoltaic panel 600 can be used to fully utilize solar energy and improve the power generation efficiency.

[0064] In the embodiment, the thin-film photovoltaic panel 600 arranged on the top of the wind force collector 500 generates electricity, which can be conducted out through the conductive ring and the graphite electrode. After rectification with electricity generated by other thin-film photovoltaic panels 600, the electricity is uniformly sent to the energy storage battery at the bottom of the generator set 400 for energy storage.

[0065] In addition, in the embodiment, the power generation device 10 further comprises a lightning protection device 700 arranged on the top of the wind force collector 500. The lightning protection device 700 can be a lightning rod. The lightning protection device 700 can prevent the power generation device 10 from being damaged by lightning in rainy weather, and improve the overall safety of the power generation device 10.

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

[0067] In summary, during the process of power generation in the breeze environment, the power generation equipment 10 can absorb the heat radiation of sunlight through the heat energy air inlet assembly 200, so as to realize the expansion and upward movement of the gas in the flow channel under the condition of being heated, and form a flowing and high-pressure gas flow in the flow channel. Since the air inlet channel 311 in the fan blade 310 is in communication with the flow channel, the high-pressure gas flow can flow into the air inlet channel 311 and be guided out from the first air outlet 312. Since the first air outlet 312 is arranged in the form of a Laval nozzle, the wind pressure and flow rate of the air outlet can be further improved, forming the condition that the gas flow is sprayed out at the first air outlet 312, and the reaction force of the sprayed gas flow can promote the rotation of the fan 300, so that the fan 300 can be stably rotated by the action of the heat radiation of sunlight even in the breeze environment, 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. Further, the wind power collector 500 in the power generation equipment 10 can also guide the wind power to the fan 300 to supplement the wind power to the fan 300, further ensuring the stable rotation of the fan 300 in the breeze environment, and can stably generate power, which is beneficial to improve the power generation efficiency. In addition, in the power generation equipment 10, when in the environment with wind, the rotation of the fan 300 can be realized directly by the wind power to generate wind power; when in the breeze environment, stable power generation in the breeze environment can be realized based on the heat energy air inlet assembly 200; and the thin-film photovoltaic panel 600 is also arranged to generate solar power. That is, the power generation equipment 10 has the functions of wind power generation, single breeze power generation and solar power generation, and can not only adapt to various different environments, but also improve the power generation efficiency.

[0068] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements within the technical range disclosed by the present application can be easily thought by those skilled in the art, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
