The area of ​​the fan-shaped structure that constitutes the air convection channel is not fixed, but can be automatically adjusted according to the wind direction. When half of the fan-shaped structure composed of a part of the blades rotates to the leeward side, several blades will automatically move outward based on the radius of the tower body, so that the area of ​​this half fan-shaped structure increases. Due to the obstruction of the tower body, there is a pressure difference between the two sides of the leeward side and the leeward side, and more air will be squeezed into the leeward side by the pressure difference. At this time, expanding the area of ​​the half fan-shaped structure on the leeward side can increase the capture amount of air convection and increase the rotation speed. The area of ​​the half fan-shaped structure on the windward side is smaller, and can effectively resist wind resistance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] For example 1, please refer to Figure 1-Figure 2 A power generation device based on air convection includes a tower base 100, characterized in that a tower body 110 is provided on the tower base 100, and a rotating drum 200 is rotatably provided on the tower body 110.

[0037] The tower 110 further includes a plurality of blades 300 , which are distributed in a fan shape based on the central axis of the tower body 110 for capturing air convection. The plurality of blades 300 are connected to the rotating drum 200 via a connecting mechanism 400 .

[0038] A power generation mechanism 500 is provided in the tower base 100 , and the power generation mechanism 500 includes a turbine generator 510 , a gear box 520 and a rotating shaft 530 . The rotating shaft 530 is transmission-connected to the rotating drum 200 , and the rotating shaft 530 is transmission-connected to the rotor of the turbine generator 510 through the gear box 520 .

[0039] The air convection in the environment drives the blades 300 and the drum 200 to rotate, and the drum 200 then drives the rotor of the turbine generator 510 to rotate through the transmission of the shaft 530 and the gear box 520 to generate electricity.

[0040] A cavity 310 is opened inside the blade 300, and a reinforcing rib 320 is provided on the blade 300. The connecting mechanism 400 includes a plurality of first sliding grooves 410 circumferentially opened on the rotating drum 200. Z-shaped rods 420 are slidingly arranged in the plurality of first sliding grooves 410, and the Z-shaped rods 420 are connected to the blade 300 through three connecting rods 430.

[0041] In this embodiment, air convection power generation is based on the thermodynamic principle that air is heated unevenly, with the heated air expanding and rising, while the cooled air sinks.

[0042] On the rotating drum 200, which is rotatably mounted at the top of the tower body 110, a ring of blades 300 forms a fan-shaped structure, with larger blades at the bottom and smaller blades at the top. This fan-shaped structure creates a channel to assist and capture air convection. Air convection is a constant presence in various natural environments, so the blades 300 and the rotating drum 200 can rotate continuously. For the specific aeronautical principles of how air convection drives the ring of blades 300, please refer to the air convection power generation device published in CN201144767Y.

[0043] When the drum 200 rotates, the rotating shaft 530 is driven to rotate. The rotating shaft 530 drives the rotor of the turbine generator 510 through the transmission of the gear box 520. The turbine generator 510 drives the power generation module installed inside to generate current. The kinetic energy of the air is converted into mechanical energy, and then the mechanical energy is converted into electrical energy. In addition, it can be equipped with a voltage control module, a power output module and an auxiliary power supply. The output end of the power generation module is connected to a voltage control module for voltage stabilization to ensure the stability of the output voltage. The stable electrical energy is transmitted to the connected electrical equipment through the power output module to complete the entire power generation process. The voltage control module and the auxiliary power supply ensure the stability of the power supply. The above-mentioned power generation module, power output module and voltage control module are conventional technical means, and their specific structure and working principle are not described in detail.

[0044] The blades 300 can be made of a fiber-reinforced resin composite material, offering structural stability, high strength, long service life, and excellent aging resistance. Utilizing a pultrusion process, the composite material is hollow and features two reinforcing ribs 320 for enhanced structural strength. Three connecting rods 430, one for each blade 300, form a triangular structure, ensuring stability and a secure connection.

[0045] This device is independent of ambient wind speed, allowing for a wider range of applications. It is particularly suitable for locations with very low average air volume but ample ambient heat, such as those in dry and hot regions. Furthermore, it can be applied to buildings. By setting up appropriate air circulation systems and utilizing temperature differences inside and outside the building, it can power various devices, thereby improving production efficiency.

[0046] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 6 An adjusting mechanism 600 is provided in the tower body 110. The adjusting mechanism 600 includes two first discs 610. The first disc 610 located on the lower side is provided in the tower body 110, and the first disc 610 located on the upper side is provided in the rotating drum 200. A valve member 620 is provided on the first disc 610 located on the upper side.

[0047] An air supply assembly 630 is provided on each of the two first discs 610, wherein half of the first chute 410 is connected to the upper port of the valve component 620 through the first disc 610 located on the upper side, and the other half of the first chute 410 is connected to the lower port of the valve component 620 through the first disc 610 located on the lower side. An air bag 640 is provided on the valve component 620, and compressed gas is stored in the air bag 640. The inner cavity of the air bag 640 is connected to the inner cavity of the valve component 620 through a number of connecting pipes 650.

[0048] The regulating mechanism 600 also includes a control assembly 660. When the plurality of blades 300 rotate along with the rotating drum 200, the control assembly 660 controls the airbag 640 to introduce compressed gas into the half of the first chute 410 that rotates to the side facing away from the wind direction according to the wind direction, thereby causing the half of the Z-shaped rod 420 and the blades 300 on the side facing away from the wind direction to move toward the outside of the tower body 110 to expand the fan-shaped area and increase the amount of captured air convection.

[0049] The air supply assembly 630 includes an air groove 631 opened on the first disc 610, and the air groove 631 is connected to the port of the rotating drum 200. A second disc 632 is provided on the first disc 610, and a third disc 633 is provided on the second disc 632. A connecting cavity 634 is opened on the third disc 633, and a first connecting hole 635 is opened on the second disc 632. The air groove 631 is connected to the connecting cavity 634 through the first connecting hole 635.

[0050] The air supply assembly 630 also includes a second slide groove 636 opened on the third disc 633. The second slide groove 636 is connected to the connecting cavity 634 through a second connecting hole 637. The Z-shaped rod 420 is slidably connected in the second slide groove 636. The Z-shaped rod 420 is elastically connected to the inner wall of the second slide groove 636 through a spring 638.

[0051] In this embodiment: Usually when the wind speed in the environment reaches a certain value, it will affect the capture of air convection. Since the drum 200 and the plurality of blades 300 rotate based on air convection, a high wind speed will also cause wind resistance to the rotation of the drum 200 and the plurality of blades 300.

[0052] To this end, a plurality of Z-shaped rods 420 are configured to be retractable based on the radius of the drum 200. The first disc 610 located on the lower side is fixed to the tower body 110, while the second disc 632 and the third disc 633 are nested layer by layer on the first disc 610, and their positions are also fixed. The drum 200 is rotatably connected to the third disc 633 located on the lower side. The first disc 610 on the upper side is rotatably mounted on the drum 200, and its position can be adjusted. The valve member 620 is fixed to the first disc 610 on the upper side. The upper and lower ports of the valve member 620 can be rotatably connected to the ports of the two air grooves 631, and sealing rings can be added to ensure sealing performance.

[0053] The upper air groove 631 connects to the left half of the first chute 410, which is designated as the blades 300 of group A. The lower air groove 631 connects to the right half of the first chute 410, which is designated as the blades 300 of group B. When the blades 300 of group A rotate to the windward side, the blades 300 of group B are located on the leeward side. At this time, the air bag 640 fills the lower air groove 631 with compressed gas.

[0054] Gas within the gas groove 631 sequentially passes through the first connecting hole 635, the connecting cavity 634, and the second connecting hole 637, pushing the Z-shaped rod 420 outward. The spring 638 is used to maintain the Z-shaped rod 420 inward and reset it in normal operation. A good seal is established between the Z-shaped rod 420 and the inner wall of the second chute 636, preventing gas from leaking to the right of the Z-shaped rod 420. This allows the Z-shaped rod 420 and blades 300 of group b to move outward in the radial direction of the tower body 110, increasing the area of ​​the leeward portion of the fan-shaped structure and thereby increasing the amount of captured airflow.

[0055] Assuming that the airflow is from right to left, since the tower body 110 is erected and blocks part of the space on its left side, the atmospheric pressure of the airflow on the front and rear sides of the tower body 110 is low. Therefore, more air will be squeezed into the left side of the tower body 110 from the front and rear sides. At this time, the fan-shaped structure on the left side is expanded to capture more air convection.

[0056] The half fan-shaped structure formed by the blades 300 of group a on the right side has a smaller area, which can reduce wind resistance.

[0057] Example 3: This example is an improvement made on the basis of Example 2. For details, please refer to Figures 1-8 Two control components 660 are symmetrically arranged based on the valve component 620. The control component 660 includes a valve core 661 slidingly arranged in the valve component 620, a guide rod 662 is arranged on the valve core 661, a connecting plate 663 is arranged on the guide rod 662, and a pressure plate 664 is arranged on the connecting plate 663. The pressure plate 664 is arranged in a semi-circular shape and is tightly attached to the airbag 640.

[0058] A rotating disk 670 is provided on the rotating drum 200 , a connecting disk 680 is provided on the rotating disk 670 , and the rotating shaft 530 is provided on the connecting disk 680 .

[0059] The control assembly 660 further includes a guide slot 665 defined in the turntable 670 , and the guide rod 662 is slidably connected in the guide slot 665 .

[0060] The guide groove 665 includes a first arc segment 6651, a second arc segment 6652 and two inclined segments 6653. The first arc segment 6651 is close to the middle of the valve member 620, and the second arc segment 6652 is away from the middle of the valve member 620. The two ends of the first arc segment 6651 are connected to the two ends of the second arc segment 6652 through the two inclined segments 6653 respectively.

[0061] The control component 660 also includes a first sealing groove 666 opened in the valve component 620, which is engaged with the port of the valve core 661. A one-way valve 667 is provided in the valve core 661, and the one-way valve 667 is used to limit the gas in the gas groove 631 to flow into the valve component 620 in one direction.

[0062] A sealing plate 669 is provided on the guide rod 662 , a second sealing groove 668 is defined on the valve member 620 , and the sealing plate 669 is slidably connected to the second sealing groove 668 .

[0063] The first disc 610 located on the upper side is rotatably connected to the drum 200 , and a wind vane 690 is provided on the first disc 610 located on the upper side.

[0064] In this embodiment, since the wind direction is variable, it is necessary to control the opening and closing of both ends of the valve member 620 according to the wind direction. First, the wind vane 690 extends outside the tower body 110, and can drive the first disc 610 and the valve member 620 located on the upper side to rotate according to the wind direction.

[0065] like Figure 3 As shown in FIG, in the initial state, the rotating drum 200 and rotating disk 670 are positioned with the second arc segment 6652 at the rear and the first arc segment 6651 at the front. Assuming the airflow direction is from right to left, the wind vane 690 drives the valve member 620 to a position where the upper guide rod 662 is on the left, and the lower guide rod 662 is on the right. When the half of the fan-shaped structure corresponding to group a rotates to the left, the rotating disk 670 rotates with the rotating drum 200 to the second arc segment 6652 and reaches the left side.

[0066] During this rotation process, the upper guide rod 662 moves from the first arc segment 6651 in the upper guide groove 665 through the inclined segment 6653 to the second arc segment 6652, and the upper guide rod 662 is now raised, while the lower guide rod 662 remains in the first arc segment 6651 in the lower guide groove 665.

[0067] At this point, the lower valve core 661 engages with the lower first sealing groove 666, while the lower one-way valve 667 restricts airflow to the center of the valve element 620. Therefore, air in the center of the valve element 620 does not flow into the lower air groove 631, preventing the outward movement of the half of the blades 300 in group B. The fan-shaped structure formed by the half of the blades 300 facing the windward side remains unchanged.

[0068] As the upper guide rod 662 moves upward, it drives the lower pressure plate 664, which is connected to it via the connecting plate 663, upward, thereby squeezing the airbag 640 and allowing the compressed gas in the airbag 640 to enter the middle portion of the valve member 620 through the connecting pipes 650. At this time, the upper valve core 661 moves upward along with the guide rod 662, separating the valve core 661 from the first sealing groove 666. The gas in the middle portion of the valve member 620 can then flow upward through the gap between the outer surface of the upper valve core 661 and the inner wall of the valve member 620, entering the upper gas groove 631 and driving the blades 300 of group a to move outward, thereby expanding the area of ​​the half of the fan-shaped structure that now reaches the leeward side.

[0069] When the drum 200 continues to rotate counterclockwise so that the upper guide rod 662 slides from the second arc segment 6652 to the first arc segment 6651, the upper guide rod 662 drops, and the airbag 640 is not squeezed and restored. Then, under the action of air pressure, the gas used to push the blades 300 of group a returns to the airbag 640 through the upper one-way valve 667.

[0070] This goes on and on, and no matter which set of blades 300 constitutes a half fan-shaped structure, the area will be expanded when it rotates to the leeward side, and will be restored when it rotates to the windward side.

[0071] The sealing plate 669 slides in the second sealing groove 668 along with the guide rod 662. The length of the second sealing groove 668 is sufficient so that the sealing plate 669 can always be in the second sealing groove 668 to maintain the sealing performance.

[0072] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
