Description

Technical Field

[0001] The present invention relates to the technical field of air energy power generation, and in particular to a modular air energy power generation device. Background Art

[0002] Air power generation is a technology that uses the energy in the air to generate electricity. Common air power generation technologies include wind power generation and compressed air energy storage. Through wind turbines, the kinetic energy of wind is converted into electrical energy. This is a mature technology that is widely used around the world.

[0003] With the intensification of the global energy crisis and the enhancement of environmental protection awareness, wind energy, as a clean and renewable energy source, has received widespread attention and application. Most of the existing wind power generation equipment relies on large wind turbines, which use wind power to drive the blades to rotate to generate electricity. Although this type of wind power generation equipment is technically mature and can effectively utilize wind energy resources, it still has some limitations and disadvantages.

[0004] Existing wind power generation equipment is usually a large wind turbine with huge blades and a large footprint. It requires a special geographical location (such as an open field, a high tower, etc.) for installation. This large-volume equipment limits the application of wind power generation technology in the field of miniaturization and modularization, making it difficult to install and use in limited spaces such as cities and building roofs. In addition, traditional wind power generation equipment is highly dependent on wind direction and wind speed. In order to ensure the efficiency of the equipment, it is usually necessary to work under specific wind direction and wind speed conditions. When the wind direction changes or the wind speed is too high or too low, the power generation efficiency of the existing equipment will drop significantly, and even equipment damage may occur. Especially when the wind speed is too high, the high-speed rotation of the blades may cause increased mechanical stress, increasing the maintenance and use costs of the equipment. At the same time, the design of existing wind power generation equipment is usually a fixed structure, which is difficult to achieve modular assembly and flexible splicing. This non-modular design makes the equipment less adaptable in different environments and difficult to flexibly adjust according to specific application scenarios, resulting in limited use of the equipment. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a modular air energy power generation device, which solves the problem of the large limitations of wind power generation in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a modular air energy power generation device, comprising a first air duct and a second air duct, the first air duct and the second air duct are detachably installed through a disassembly mechanism, a one-way air outlet mechanism is detachably installed at the opposite ports of the first air duct and the second air duct, the second air duct comprises a central ventilation part, the openings on both sides of the central ventilation part are respectively provided with an air inlet part and an air outlet part, an adjustment mechanism is arranged inside the central ventilation part, and the two groups of the adjustment mechanisms are connected by a transmission mechanism;

[0007] The adjusting mechanism includes a central rotating shaft, both ends of which pass through and are rotatably connected to the inner wall of the central ventilation part, and the bottom end of the central rotating shaft is connected to the input shaft of the generator, and the rotation of the input shaft of the generator is achieved by the rotation of the central rotating shaft. Sliding rods are slidably connected to the inner walls on the upper and lower sides of the central rotating shaft, respectively, and fan blades are fixedly connected to the opposite outer walls of the upper and lower groups of sliding rods, and the two groups of fan blades are hinged to the outer wall of the central sliding rod.

[0008] Preferably, a driving motor is fixedly connected to the inner wall of the central rotating shaft, a gear is fixedly connected to the output shaft of the driving motor, a rotating ring is rotatably connected to the inner wall of the central rotating shaft, and the outer ring of the gear is meshed with the inner ring of the rotating ring.

[0009] Preferably, a plurality of guide rails are fixedly connected to the outer wall of the rotating ring, the interior of the guide rails is hollow, the inner end of the center slide rod is slidably connected to the inner wall of the center shaft, and the outer wall of the center shaft is provided with a transverse groove for the center slide rod to move.

[0010] Preferably, the inner end of the center slide rod is fixedly connected to a slider, which is cylindrical and has upper and lower ends slidably connected to the inner wall of the guide rail. When the slider moves to one side, it drives the center slide rod to move to one side, thereby controlling the deformation direction of the two groups of fan blades.

[0011] Preferably, the transmission mechanism includes a first bevel gear, the central axis of the first bevel gear is fixedly connected to the top of the central rotating shaft, the side of the first bevel gear is meshed with a second bevel gear, the top of the second bevel gear is meshed with a third bevel gear, and the central axis of the third bevel gear is fixedly connected to the bottom end of the central rotating shaft of the first air duct.

[0012] Preferably, a bracket is fixedly connected to the bottom end of the first air duct, and the central axis of the second bevel gear is rotatably connected to the inner wall of the bracket, so that the second bevel gear is supported by the bracket.

[0013] Preferably, the disassembly mechanism includes a first sleeve and a second sleeve, the top end of the first sleeve is fixedly connected to the bottom end of the first air duct, and the bottom end of the second sleeve is fixedly connected to the top end of the second air duct.

[0014] Preferably, the first sleeve and the second sleeve are plugged into each other, and after being plugged in, a relatively sealed environment can be formed inside. Several groups of mounting plates are fixedly connected around the outer wall of the first sleeve.

[0015] Preferably, the outer walls of the first sleeve and the second sleeve are each provided with a plurality of groups of bolt holes, and the first sleeve and the second sleeve are fixed to each other via a mounting plate and bolts.

[0016] Preferably, the one-way air outlet mechanism includes a baffle, which is hinged on the inner wall of the air outlet portion of the second air duct, and the maximum opening and closing angle of the baffle is from ° to °. A transverse partition is fixedly connected to the inner wall of the air outlet portion, and the transverse partition prevents the baffle from folding inward, and both the baffle and the transverse partition are removable.

[0017] Working principle: Working principle: Install the entire device at a position with crosswind, install the air outlet mechanisms on the first and second air ducts opposite to each other, and fix the bottom end of the central rotating shaft of the second air duct to the input shaft of the generator through a coupling. When encountering wind from left to right, the fan blades in the second air duct at the bottom can drive the central rotating shaft to rotate, thereby driving the input shaft of the generator at the bottom to rotate and generate electricity. When encountering wind from right to left, the central rotating shaft in the first air duct rotates and drives the third bevel gear to rotate. The third bevel gear drives the first bevel gear to rotate through the second bevel gear. The first bevel gear drives the central rotating shaft in the second air duct to rotate. The first bevel gear can make the direction of rotation of the central rotating shaft in the first air duct transmitted to the central rotating shaft in the second air duct through the first bevel gear, the third bevel gear and the second bevel gear, thereby ensuring that the central rotating shaft in the second air duct rotates in the same direction, thereby increasing the stability of power generation.

[0018] At the same time, the first air duct and the second air duct can adjust the actual installation direction through the mounting plate, the first sleeve, and the second sleeve. There is no need to set them in parallel. The wind direction is adjusted according to the actual scenario. At the same time, when the wind speed is too fast, the gear is driven by the driving motor to rotate, so that the gear drives the rotating ring to rotate, and the guide rail drives the slider and the center slide bar to move to one side, so that the fan blade is deformed into a ">" shape, and its protruding part faces the wind. At this time, the upper and lower parts of the fan blade both leak a large gap. At this time, the wind is cut and flows out along the gap, which can effectively reduce its rotation speed. At the same time, when the wind force is relatively small, the fan blade can also be deformed in the opposite direction, so that the wind force accumulates in the middle of the fan blade, increasing the thrust of the wind.

[0019] The present invention provides a modular air energy power generation device, which has the following beneficial effects:

[0020] 1. The present invention adopts a modular disassembly mechanism between the first air duct and the second air duct, which can realize the rapid splicing and disassembly of the air ducts. The modular installation method is adaptable to different installation scenarios. Users can flexibly adjust the number and arrangement of the air ducts according to specific needs, thereby increasing the application scope of the equipment and being suitable for complex geographical environments.

[0021] 2. The present invention uses an internally arranged bevel gear transmission mechanism to enable the central shafts in different air ducts to rotate synchronously. No matter how the wind direction changes, it can ensure that the generator input shaft maintains the same rotation direction. Even when the wind direction changes, the power generation stability of the equipment can be guaranteed, reducing the impact of wind direction changes on power generation efficiency.

[0022] 3. The fan blades in the adjustment mechanism of the present invention can automatically deform according to the wind speed to form different shapes to adjust the area of ​​action of the wind on the fan blades. When the wind speed is high, the windward area of ​​the fan blades is reduced, the rotation speed is reduced, and the equipment is prevented from being overloaded; when the wind speed is low, the windward area of ​​the fan blades is increased, the wind thrust is enhanced, and the efficiency of wind energy utilization is improved.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] Please see attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides a modular air energy power generation device, including a first air duct 1 and a second air duct 2. The first air duct 1 and the second air duct 2 are detachably installed through a disassembly mechanism 3. The modular installation method enables them to be assembled and spliced ​​with each other to adapt to more scenarios. The first air duct 1 and the second air duct 2 are detachably installed with a one-way air outlet mechanism 4 at the opposite ports. The second air duct 2 includes a central ventilation part 101. The openings on both sides of the central ventilation part 101 are respectively provided with an air inlet part 102 and an air outlet part 103. The interior of the central ventilation part 101 is provided with an adjustment mechanism 5. The interior of the first air duct 1 is provided with the same adjustment mechanism 5. The two groups of adjustment mechanisms 5 are connected by a transmission mechanism 6, and their rotation directions are consistent.

[0037] Please see attached Figure 6 -Attached Figure 8 And attached Fig.10The adjusting mechanism 5 includes a central rotating shaft 501, both ends of which pass through and are rotatably connected to the inner wall of the central ventilation part 101, and the bottom end of the central rotating shaft 501 is connected to the input shaft of the generator, and the rotation of the generator is realized by the rotation of the central rotating shaft 501. The power generation principle here belongs to the existing technology well known to those skilled in the art, so it will not be described in detail. The inner walls on the upper and lower sides of the central rotating shaft 501 are respectively slidably connected with sliding rods 502, and the upper and lower groups of sliding rods 502 are fixedly connected with fan blades 504 on the opposite outer walls. The two groups of fan blades 504 are hinged on the outer wall of the central sliding rod 503. The two groups of fan blades 504 can rotate around the central sliding rod 503 at a certain angle, thereby changing the overall shape of the fan blades 504 to adjust according to the direction of the incoming wind. At the same time, it can change the area borne by the fan blades 504 under the premise of the same wind speed, so as to reduce the rotation speed of the central rotating shaft 501 and avoid the problem of damage to the equipment due to excessive rotation speed.

[0038] Please see attached Figure 6 -Attached Fig.10 A driving motor 505 is fixedly connected to the inner wall of the central rotating shaft 501, and a gear 508 is fixedly connected to the output shaft of the driving motor 505. A rotating ring 506 is rotatably connected to the inner wall of the central rotating shaft 501. The outer ring of the gear 508 is meshed with the inner ring of the rotating ring 506. The driving motor 505 drives the gear 508 to rotate. A plurality of guide rails 507 are fixedly connected to the outer wall of the rotating ring 506. The interior of the guide rails 507 is hollow. The inner end of the central slide bar 503 is slidably connected to the inner wall of the central rotating shaft 501, and a transverse groove is provided on the outer wall of the central rotating shaft 501 for the central slide bar 503 to move. A slider 509 is fixedly connected to the inner end of the core slide bar 503. The slider 509 is cylindrical and the upper and lower ends are slidably connected to the inner wall of the guide rail 507. When the rotating ring 506 rotates, it can drive the guide rail 507 to rotate along the center of the rotating ring 506, so that the guide rail 507 drives the slider 509 to move to one side. Since the guide rail 507 has an overall arc-shaped motion trajectory, the slider 509 will move along the inner wall of the guide rail 507 to avoid the problem of motion interference. When the slider 509 moves to one side, it will drive the center slide bar 503 to move to one side, thereby controlling the deformation direction of the two sets of fan blades 504.

[0039] Please see attached Figure 2 -Attached Figure 3The transmission mechanism 6 includes a first bevel gear 601, the central axis of the first bevel gear 601 is fixedly connected to the top of the central rotating shaft 501, the side of the first bevel gear 601 is meshed with a second bevel gear 603, the bottom end of the first air duct 1 is fixedly connected with a bracket 604, the central axis of the second bevel gear 603 is rotatably connected to the inner wall of the bracket 604, and the second bevel gear 603 is supported by the bracket 604, the top of the second bevel gear 603 is meshed with a third bevel gear 602, the central axis of the third bevel gear 602 is fixedly connected to the bottom end of the central rotating shaft 501 of the first air duct 1, and the upper and lower sets of central rotating shafts 501 are connected in series through the transmission mechanism 6, so that no matter what the wind direction is, the input shaft of the generator at the bottom end of the second air duct 2 can rotate in the same direction to ensure the stability of its power generation.

[0040] Please see attached Fig. 9 The disassembly mechanism 3 includes a first sleeve 301 and a second sleeve 302. The top end of the first sleeve 301 is fixedly connected to the bottom end of the first air duct 1, and the bottom end of the second sleeve 302 is fixedly connected to the top end of the second air duct 2. The first sleeve 301 and the second sleeve 302 are plugged into each other. After plugging in, a relatively sealed environment can be formed inside, which can protect the internal transmission mechanism 6 to transmit stably. Several groups of mounting plates 303 are fixedly connected to the outer wall of the first sleeve 301. Several groups of bolt holes are opened on the outer walls of the first sleeve 301 and the second sleeve 302. The first sleeve 301 and the second sleeve 302 are fixed to each other through the mounting plates 303 and bolts.

[0041] Please see attached Figure 4 -Attached Figure 5 The one-way air outlet mechanism 4 includes a baffle 401, which is hinged on the inner wall of the air outlet portion 103 of the second air duct 2. The maximum opening and closing angle of the baffle 401 is 30° to 45°. A transverse partition 402 is fixedly connected to the inner wall of the air outlet portion 103.
