A low-wind-speed power generation device

Abstract

This invention relates to the field of wind power generation equipment technology, specifically a low-wind-speed power generation device, including an outer frame, a flow guiding component, and a positioning component. The flow guiding component is rotatably mounted on the top of the outer frame to optimize wind direction. A positioning component is located on top of the flow guiding component for positioning it. The airflow direction creates an angle with the side of the main wing, resulting in inconsistent air pressure on both sides of the main wing. Therefore, the inside of the main wing experiences a torsional force towards the side with lower air pressure. This difference in wind pressure on both sides of the main wing causes it to rotate until the wind pressure on both sides is equal. The rotation of the main wing drives the turntable, wind guide shroud, partition, and dustproof net to rotate together via the top cover. This ensures that the air inlet of the wind guide shroud always faces the wind direction after a change in wind direction, thus not affecting the power generation performance of the device even with a change in wind direction, guaranteeing efficient power output and increasing power generation capacity.

Description

Technical Field

[0001] This invention relates to the field of wind power generation equipment technology, specifically a low wind speed power generation device. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of a wind turbine, a generator (including a device), a directional control unit (tail fin), a tower, a speed limiting safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple: the wind turbine rotates under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the wind turbine shaft. The generator rotates under the drive of the wind turbine shaft to generate electricity. Broadly speaking, wind energy is also solar energy, so a wind turbine can also be said to be a type of thermal energy utilization generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] According to a Chinese patent application with publication number CN115875203A, a new energy wind power generation energy storage device is disclosed. During maintenance, no high-altitude work is required; maintenance can be performed on the ground only, reducing the operational risks and labor costs of maintenance. The energy-absorbing component can reduce the blade speed when the wind is too strong, thereby preventing the blades from breaking due to excessive speed. The energy storage component realizes automatic energy storage and release without the need for active intervention control. The blades of the aforementioned wind turbine are installed vertically, resulting in a high center of gravity and insufficient overall stability. In addition, the wind turbine's direction adjustment relies on passive adjustment by a regulating motor, which is not ideal in terms of cost and ease of use, and lacks braking measures, resulting in insufficient stability of the wind turbine blades. Therefore, we propose a low-wind-speed power generation device to solve the above technical problems. Summary of the Invention

[0007] As a preferred embodiment of the present invention, a generator is fixedly installed inside the outer frame, and blades are fixedly installed on the shaft end of the generator, with the blades located at the bottom of multiple air distribution vents.

[0008] As a preferred embodiment of the present invention, a flow guide is fixedly installed on the inner wall of the outer frame, the flow guide is located between the generator and the blades, and a plurality of air outlets are provided through the outer wall of the outer frame at equal angles, the air outlets being located around the flow guide.

[0009] As a preferred embodiment of the present invention, a plurality of longitudinally and laterally distributed air guide hoods are fixedly installed on the top of the turntable. The air guide hoods are located around the opening of the air distribution port, and the inlet direction of the air distribution port is directly opposite to the air inlet direction of the air guide hood.

[0010] As a preferred embodiment of the present invention, a dustproof net is fixedly installed at the air inlet end of the air guide shroud, and the dustproof net is fastened to the air guide component by bolt fixing.

[0011] As a preferred embodiment of the present invention, the main wing has an internal mounting groove, the secondary wing is located inside the mounting groove, the gap between the outer wall of the secondary wing and the inner wall of the mounting groove is 0.3 to 0.5 cm, the vertical shaft is connected to the top cover through a bearing, the connecting sleeve is located inside the top cover and at the top of the air guide cover, and the end of the push-pull pin abuts against the top of the cam strip.

[0012] As a preferred embodiment of the present invention, a sliding groove is provided at one end of the top of the turntable near the positioning component, and the outer wall of the positioning rod is slidably connected to the inner wall of the sliding groove.

[0013] As a preferred embodiment of the present invention, a limiting arc groove is formed on the side of the cam bar away from the push-pull shaft pin, a fixing plate is fixedly installed on the top wall of the top cover, a limiting rod is fixedly installed at the bottom of the fixing plate, and the limiting rod is located inside the limiting arc groove.

[0014] As a preferred embodiment of the present invention, a reset swing arm is fixedly installed on the lower part of one side of the connecting sleeve near the limiting arc groove, and a slot is opened at the end of the reset swing arm away from the connecting sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by placing the blades horizontally inside the outer frame, the center of gravity of the equipment can be lowered, which is beneficial to improving the stability of the equipment and also facilitates installation. On the other hand, the angle between the airflow direction and the side of the main wing causes the air pressure on the two sides of the main wing to be inconsistent. Therefore, the inside of the main wing will be subjected to a torsional force towards the side with lower air pressure. At this time, the different wind pressure on the two sides of the main wing causes the main wing to rotate until the wind pressure on the two sides of the main wing is the same. The rotation of the main wing drives the turntable, air guide hood, partition and dustproof net to rotate together through the top cover. This ensures that after the wind direction changes, the air inlet of the air guide hood is always facing the wind direction. Therefore, the power generation performance of this equipment will not be affected when the wind direction changes, ensuring efficient power output and improving power generation capacity.

[0018] 2. In this invention, when the wind pressure on both sides of the main wing is equal, the rebound force of the spring bar drives the reset swing arm, along with the connecting sleeve and the cam bar, to rotate and reset. During the rotation and reset of the cam bar, the upward thrust on the push pin gradually ends, and the rebound force of the top spring is gradually released, pushing the positioning rod downward along the inner wall of the slide groove until the bottom of the positioning rod abuts against the top of the outer frame again, thus tortuously braking the flow guide assembly and the outer frame again, ensuring that the flow guide assembly will not rotate arbitrarily during the power generation process, thereby ensuring the stability of the equipment operation.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-10 The technical solution provided by the present invention specifically includes the following embodiments:

[0032] Example 1: A low-wind-speed power generation device includes an outer frame 100, a flow guiding component 200, and a positioning component 300. The flow guiding component 200 is rotatably mounted on the top of the outer frame 100 and is used to optimize the wind direction. The positioning component 300 is located on the top of the flow guiding component 200 and is used to position the flow guiding component 200. The flow guiding component 200 includes a turntable 201 rotatably mounted on the top of the outer frame 100. A wind guide hood 202 is fixedly mounted on the top of the turntable 201. Multiple equally spaced partitions 203 are fixedly arranged on the inner wall of the wind guide hood 202, dividing the interior of the wind guide hood 202 into multiple cavities. Multiple longitudinally and transversely distributed air distribution ports 204 are opened through the bottom of the turntable 201. The air vent 204 is located inside the cavity. Multiple longitudinally and transversely distributed air ducts 205 are fixedly installed on the top of the turntable 201. The air ducts 205 are located around the opening of the air vent 204, and the inlet direction of the air vent 204 is directly opposite the air inlet direction of the air guide hood 202. A top cover 206 is fixedly installed on the top periphery of the turntable 201. A main wing 207 is fixedly installed on one side of the top of the top cover 206. A dustproof net 700 is fixedly installed at the air inlet end of the air guide hood 202. The dustproof net 700 is fastened to the air guide assembly 200 by bolts. A universal connecting frame 208 is fixedly installed on the top of the outer frame 100. The air guide hood 202 is rotatably connected to the outer frame 100 through the universal connecting frame 208.

[0033] A generator 400 is fixedly installed inside the outer frame 100. A blade 500 is fixedly installed on the shaft end of the generator 400. The blade 500 is located at the bottom of multiple air distribution ports 204. A guide frame 600 is fixedly installed on the inner wall of the outer frame 100. The guide frame 600 is located between the generator 400 and the blade 500. Multiple air outlets 101 distributed at equal angles are opened through the outer wall of the outer frame 100. The air outlets 101 are located around the guide frame 600.

[0034] In this embodiment, the device is positioned at the installation location using a stable bracket at its bottom. The device's power output line is connected to the input of an external energy storage device. During use, external airflow passes through the dust filter 700 to remove particles and dust before entering the interior of the air guide shroud 202. Due to the obstruction of multiple baffles 203, the airflow entering the air guide shroud 202 is divided into multiple streams, which sequentially enter the cavities formed by the baffles 203. Subsequently, the airflow is guided by multiple air distribution vents 204, optimizing the airflow direction and allowing the airflow to enter the air distribution vents 204 more efficiently. The airflow then flows downward from the bottom of the air distribution vents 204, creating a blowing effect on the blades 500. This causes the blades 500 to rotate, driving the shaft of the generator 400 to rotate, thereby generating electricity. It continuously supplies electrical energy to external energy storage devices. During use, if the direction of the external airflow changes, the airflow direction will form an angle with the side of the main wing 207, resulting in inconsistent air pressure on the two sides of the main wing 207. Therefore, the inside of the main wing 207 will be subjected to a torsional force towards the side with lower air pressure. At this time, the different wind pressure on the two sides of the main wing 207 will cause the main wing 207 to rotate until the wind pressure on both sides of the main wing 207 is the same. The rotation of the main wing 207 will drive the turntable 201, the air guide hood 202, the partition 203, and the dustproof net 700 to rotate together through the top cover 206. This ensures that the air inlet of the air guide hood 202 always faces the wind direction after the wind direction changes, so that the power generation performance of this equipment will not be affected when the wind direction changes, ensuring efficient output of electrical energy and improving power generation capacity.

[0035] It should be noted that after the blades 500 rotate, the air entering the outer frame 100 is guided by the air guide 600 and then discharged to the outside of the outer frame 100 through multiple air outlets 101, thereby creating an air circulation effect between the inside and outside of the outer frame 100.

[0036] Example 2: The positioning component 300 includes a vertical shaft 301 rotatably mounted inside the top cover 206. A secondary wing 302 is fixedly mounted on the top of the vertical shaft 301, and a connecting sleeve 303 is fixedly mounted on the bottom of the vertical shaft 301. A cam strip 304 is fixedly mounted on the outer wall of the connecting sleeve 303. A top spring 306 is fixedly mounted on the top wall of the top cover 206. A positioning rod 305 is fixedly mounted on the bottom of the top spring 306. The positioning rod 305 passes through the interior of the turntable 201, and its bottom abuts against the top of the outer frame 100. A push-pull pin 307 is fixedly mounted on the side of the positioning rod 305 near the connecting sleeve 303. A sliding groove 2001 is opened through the top of the turntable 201 near the positioning component 300. The outer wall of the positioning rod 305 is slidably connected to the inner wall of the sliding groove 2001.

[0037] A reset swing arm 3011 is fixedly installed on the lower part of one side of the connecting sleeve 303 near the limiting arc groove 308. A slot 3012 is opened at the end of the reset swing arm 3011 away from the connecting sleeve 303. A spring strip 3013 is fixedly installed on the top wall of the top cover 206. The spring strip 3013 is inserted into the inside of the slot 3012.

[0038] Specifically, in this embodiment, during use, if the direction of the external airflow changes, the airflow direction forms an angle with the side of the main wing 207, resulting in inconsistent air pressure on the two sides of the main wing 207. Therefore, the inside of the main wing 207 will be subjected to a torsional force towards the side with lower air pressure. Initially, due to the elastic force of the top spring 306, the positioning rod 305 is pressed downward, causing the bottom of the positioning rod 305 to abut against the top of the air outlet 101, producing a braking effect. Therefore, the turntable 201 will not rotate. The turntable 201 not rotating means that the top cover 206 will exert a restraining effect on the main wing 207. The braking effect prevents the main wing 207 from rotating. However, when the main wing 207 experiences different pressures on both sides, the secondary wing 302 also experiences different pressures on both sides, causing the secondary wing 302 to rotate within the mounting groove 2007 towards the side with less pressure. This rotation of the secondary wing 302, through the connection of the vertical shaft 301, drives the connecting sleeve 303 and the cam strip 304 to rotate together. Simultaneously, the rotation of the connecting sleeve 303 also drives the reset swing arm 3011 and the slot 3012 to rotate together, causing the elastic strip 3013 to bend elastically, thus allowing the connecting sleeve 303 to rotate. During the reset and energy storage process, the rotation of the cam strip 304 exerts an upward thrust on the push pin 307, causing the positioning rod 305 to move upward. This compresses the top spring 306, storing energy to reset the positioning rod 305 downward. As the positioning rod 305 moves upward, its bottom separates directly from the top of the outer frame 100. This means the braking effect between the positioning rod 305 and the outer frame 100 ends. At this point, the different wind pressures on both sides of the main wing 207 cause it to rotate until the wind pressures on both sides of the main wing 207 are equal. Once the wind pressures on both sides of the main wing 207 are equal, the spring... The rebound force of bar 3013 drives the reset swing arm 3011, together with the connecting sleeve 303 and the cam bar 304, to rotate and reset. During the rotation and reset of the cam bar 304, the upward pushing force on the push pin 307 gradually ends, and the rebound force of the top spring 306 is gradually released, pushing the positioning rod 305 down along the inner wall of the slide groove 2001 until the bottom of the positioning rod 305 abuts against the top of the outer frame 100 again, and the flow guiding component 200 and the outer frame 100 are torsional braked again to ensure that the flow guiding component 200 will not rotate arbitrarily during the power generation process, thereby ensuring the stability of the equipment operation.

[0039] Furthermore, the main wing 207 has an installation groove 2007 inside, the secondary wing 302 is located inside the installation groove 2007, the gap between the outer wall of the secondary wing 302 and the inner wall of the installation groove 2007 is 0.3 to 0.5 cm, the vertical shaft 301 is connected to the top cover 206 through a bearing, the connecting sleeve 303 is located inside the top cover 206, and the connecting sleeve 303 is located at the top of the air guide cover 202, and the end of the push-pull pin 307 abuts against the top of the cam strip 304;

[0040] By creating a mounting slot 2007 inside the main wing 207, it is convenient to install the secondary wing 302, while also avoiding interference between the main wing 207 and the secondary wing 302. A gap of 0.3 to 0.5 cm is provided between the mounting slot 2007 and the secondary wing 302 to ensure that the edge of the secondary wing 302 will not come into contact with the inner wall of the mounting slot 2007 during rotation, thereby ensuring the smooth rotation of the secondary wing 302.

[0041] Furthermore, a limiting arc groove 308 is provided on the side of the cam bar 304 away from the push pin 307, and a fixing plate 309 is fixedly installed on the top wall of the top cover 206. A limiting rod 3010 is fixedly installed at the bottom of the fixing plate 309, and the limiting rod 3010 is located inside the limiting arc groove 308.

[0042] The rotation of the cam strip 304 will drive the limiting arc groove 308 to rotate. Furthermore, under the interference of the limiting rod 3010 on the limiting arc groove 308, the rotation angle of the cam strip 304 will not be too large. In other words, it ensures that the rotation angle of the connecting sleeve 303, the vertical shaft 301 and the auxiliary wing 302 as a whole will not be too large.

[0043] In this scheme, a low-wind-speed power generation device is installed at its location using a stable support at its bottom. The device's power output line is connected to the input of an external energy storage device. During operation, external airflow passes through a dust filter 700 to remove particulate matter and dust before entering the interior of the air guide shroud 202. Due to the obstruction of multiple baffles 203, the airflow entering the air guide shroud 202 is divided into multiple streams, which sequentially enter the cavities formed by the baffles 203. Subsequently, the airflow is guided by multiple air distribution ports 204, which optimizes the airflow direction, allowing the airflow to enter the air distribution ports 204 more efficiently. The airflow then flows downward from the bottom of the air distribution ports 204, creating a blowing effect on the blades 500. This causes the blades 500 to rotate and drive the shaft of the generator 400 to rotate, thereby generating electricity and continuously supplying power to the external energy storage device.

[0044] During use, if the direction of external airflow changes, the airflow direction will form an angle with the side of the main wing 207, resulting in inconsistent air pressure on the two sides of the main wing 207. Therefore, the inside of the main wing 207 will be subjected to a torsional force towards the side with lower air pressure. Initially, due to the elastic force of the top spring 306, the positioning rod 305 is pressed downward, causing the bottom of the positioning rod 305 to abut against the top of the air outlet 101, producing a braking effect. Therefore, the turntable 201 will not rotate. The fact that the turntable 201 does not rotate means that the top cover 206 will exert a braking force on the main wing. Due to the braking effect of 207, the main wing 207 will not rotate. However, when the two sides of the main wing 207 are subjected to different pressures, the two sides of the secondary wing 302 are also subjected to different pressures, causing the secondary wing 302 to rotate inside the mounting groove 2007 towards the side with less pressure. The rotation of the secondary wing 302 drives the connecting sleeve 303 and the cam strip 304 to rotate together through the connection of the vertical shaft 301. The rotation of the cam strip 304 drives the limiting arc groove 308 to rotate, and further, under the interference of the limiting rod 3010 on the limiting arc groove 308, This prevents the cam bar 304 from rotating too much. Simultaneously, the rotation of the connecting sleeve 303 also causes the reset arm 3011 and the slot 3012 to rotate together, resulting in the elastic bending of the spring bar 3013. This stores energy for the rotary reset of the connecting sleeve 303. At the same time, the rotation of the cam bar 304 generates an upward thrust on the push pin 307, causing the positioning rod 305 to move upward. The compression spring 306 stores energy for the downward reset of the positioning rod 305. As the positioning rod 305 moves upward, its bottom separates directly from the top of the outer frame 100. In other words, the positioning... The braking action between the insertion rod 305 and the outer frame 100 ends. At this time, the main wing 207 is subjected to different wind pressures on both sides, causing the main wing 207 to rotate until the wind pressures on both sides of the main wing 207 are the same. The rotation of the main wing 207 drives the turntable 201, the air guide hood 202, the partition 203 and the dustproof net 700 to rotate together through the top cover 206. This ensures that after the wind direction changes, the air inlet of the air guide hood 202 always faces the wind direction. Therefore, the power generation performance of this equipment will not be affected when the wind direction changes, ensuring efficient power output and improving power generation capacity.

[0045] When the wind pressure on both sides of the main wing 207 is equal, the rebound force of the spring bar 3013 drives the reset swing arm 3011, together with the connecting sleeve 303 and the cam bar 304, to rotate and reset. During the rotation and reset of the cam bar 304, the upward thrust on the push pin 307 gradually ends, and the rebound force of the top spring 306 is gradually released, pushing the positioning rod 305 down along the inner wall of the slide groove 2001 until the bottom of the positioning rod 305 abuts against the top of the outer frame 100 again, and the flow guiding component 200 and the outer frame 100 are twisted and braked again to ensure that the flow guiding component 200 will not rotate arbitrarily during the power generation process, thereby ensuring the stability of the equipment operation.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
