Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation equipment, in particular to low wind speed power generation equipment. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine is generally composed of a wind rotor, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] According to a Chinese patent application with the publication number CN115875203A, a new energy wind power generation and energy storage device is disclosed. During maintenance, workers do not need to work at high altitudes, but only need to perform maintenance on the ground on the generator set, which reduces the operational risks of maintenance and reduces the labor costs of maintenance. The energy absorption component is set to reduce the rotation speed of the blades when the wind is too strong, thereby preventing the blades from breaking due to excessive rotation speed. The energy storage component is set to realize automatic energy storage and release of stored energy without the need for active intervention and control. The blades of the above-mentioned fan are installed vertically, which will result in a higher center of gravity height of the fan and insufficient overall stability. At the same time, the adjustment direction of the above-mentioned fan needs to rely on the passive adjustment of the adjustment motor, which is not superior in terms of cost and ease of use, and lacks braking measures, resulting in insufficient stability of the fan blades.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, by placing the blades horizontally inside the outer frame, on the one hand, the height of the center of gravity of the equipment can be lowered, which is beneficial to improving the stability of the equipment and is also easy to install. On the other hand, the air flow direction forms an angle with the side of the main wing, resulting in inconsistent air pressure on the two sides of the main wing. Therefore, the inside of the main wing will be subjected to a twisting effect toward the side with smaller air pressure. At this time, the two sides of the main wing are subjected to different wind pressures, causing the main wing to rotate until the wind pressures on both sides of the main wing are the same. The rotation of the main wing drives the turntable, wind guide cover, partition and dustproof net to rotate together through the top cover, so that after the wind direction changes, the air inlet end of the wind guide cover is always facing the wind direction. Therefore, when the wind direction changes, it will not affect the power generation performance of the equipment, thereby ensuring the efficient output of electric energy and improving the power generation capacity.

[0018] 2. In the present invention, when the wind pressure on both sides of the main wing is consistent, the resilience of the elastic bar drives the reset swing arm together 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-pull shaft pin gradually ends, and the resilience 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, and the guide assembly and the outer frame are torsionally braked again to ensure that the guide assembly will not rotate at will during the power generation process, thereby ensuring the stability of the equipment operation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments 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.

[0031] See also Figure 1-Figure 10 The technical solution provided by the present invention specifically includes the following embodiments:

[0032] Embodiment 1: A low wind speed power generation device, comprising an outer frame 100, a guide assembly 200 and a positioning component 300, wherein the guide assembly 200 is rotatably provided on the top of the outer frame 100, and the guide assembly 200 is used to optimize the wind direction, and a positioning component 300 is provided on the top of the guide assembly 200, and the positioning component 300 is used to position the guide assembly 200, and the guide assembly 200 comprises a turntable 201 rotatably installed on the top of the outer frame 100, and a wind guide cover 202 is fixedly installed on the top of the turntable 201, and a plurality of partitions 203 distributed at equal distances are fixedly provided on the inner wall of the wind guide cover 202, and the partitions 203 divide the interior of the wind guide cover 202 into a plurality of cavities, and a plurality of vertically and horizontally distributed air distribution ports 204 are opened through the bottom of the turntable 201 The air outlet 204 is located inside the cavity, and a plurality of air induced hoods 205 distributed vertically and horizontally are fixedly installed on the top of the turntable 201. The air induced hoods 205 are located outside the opening of the air outlet 204, and the inlet direction of the air outlet 204 faces the air inlet direction of the air guide cover 202. A top cover 206 is fixedly installed on the outer periphery of the top of the turntable 201, and 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 on the air inlet end of the air guide cover 202, and the dustproof net 700 is fastened to the guide assembly 200 by bolts. A universal connecting frame 208 is fixedly installed on the top of the outer frame 100, and the air guide cover 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, and 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. A plurality of air outlets 101 distributed at equal angles are opened through the outer wall of the outer frame 100, and the air outlets 101 are located on the periphery of the guide frame 600.

[0034] Specifically, the present embodiment is to place the present device at the installation site through a stable bracket provided at the bottom thereof, and connect the power generation output line end of the device to the input end of the external power storage device. When in use, the external airflow passes through the dustproof net 700 to filter out particulate matter and dust, and then enters the interior of the air guide cover 202. Due to the blocking of multiple partitions 203, the airflow entering the interior of the air guide cover 202 is divided into multiple streams, which sequentially enter the interior of the cavity formed by the multiple partitions 203. Subsequently, the airflow passes through the guiding effect of multiple air distribution ports 204, which can optimize the airflow direction, so that the airflow can enter the interior of the air distribution port 204 more efficiently, and flow downward from the bottom of the air distribution port 204, causing a blowing effect on the blades 500, causing the blades 500 to rotate and drive the shaft of the generator 400 to rotate, thereby causing the generator 400 to generate electricity. And it continuously transmits electric energy to the external power storage equipment. During use, if the direction of the external airflow changes, the air flow 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 twisting effect toward the side with smaller air pressure. At this time, the two sides of the main wing 207 are subjected to different wind pressures, 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 wind guide cover 202, the partition 203 and the dust net 700 to rotate together through the top cover 206, so that after the wind direction changes, the air inlet end of the wind guide cover 202 is always facing the wind direction, so that when the wind direction changes, it will not affect the power generation performance of the equipment, thereby ensuring the efficient output of electric energy and improving the power generation capacity.

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

[0036] Embodiment 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, 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 inside of the turntable 201, and its bottom abuts against the top of the outer frame 100, a push-pull shaft pin 307 is fixedly mounted on one side of the positioning rod 305 close to the connecting sleeve 303, a slide groove 2001 is penetrated through one end of the top of the turntable 201 close to the positioning component 300, and the outer wall of the positioning rod 305 is slidably connected with the inner wall of the slide groove 2001;

[0037] A reset swing arm 3011 is fixedly installed at the lower part of one side of the connection sleeve 303 close to the limiting arc groove 308, and a clamping groove 3012 is opened at one end of the reset swing arm 3011 away from the connection sleeve 303. A spring bar 3013 is fixedly installed on the top wall of the top cover 206, and the spring bar 3013 is inserted into the inside of the clamping groove 3012;

[0038] Specifically, in this embodiment, during use, if the direction of the external airflow changes, the flow direction of the air 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 twisted toward the side with lower air pressure. Initially, due to the elastic force of the top spring 306, the positioning rod 305 is pressed downward, so that the bottom of the positioning rod 305 abuts against the top of the air outlet 101, producing a braking effect. Therefore, the turntable 201 will not rotate. The turntable 201 will not rotate, which means that the main wing 207 will be restrained by the top cover 206. The braking effect is produced, so the main wing 207 will not rotate. When the two sides of the main wing 207 are subjected to pressures of different sizes, the two sides of the auxiliary wing 302 are also subjected to pressures of different sizes, causing the auxiliary wing 302 to rotate to the side with less pressure inside the accommodating groove 2007. The rotation of the auxiliary wing 302 drives the connecting sleeve 303 and the cam strip 304 to rotate together through the connection effect of the vertical shaft 301. At the same time, the rotation of the connecting sleeve 303 also drives the reset swing arm 3011 and the card slot 3012 to rotate together, causing the elastic strip 3013 to bend elastically, thereby facilitating the rotation of the connecting sleeve 303. The cam strip 304 is rotated to generate an upward thrust on the push-pull shaft pin 307, causing the positioning rod 305 to move upward, compressing the top spring 306 to generate an energy storage effect on the positioning rod 305 to reset downward, and the positioning rod 305 moves upward, and its bottom is directly separated from the top of the outer frame 100, that is, the braking effect between the positioning rod 305 and the outer frame 100 ends. At this time, the different wind pressures on both sides of the main wing 207 cause the main wing 207 to rotate until the wind pressures on both sides of the main wing 207 are the same. When the wind pressures on both sides of the main wing 207 are consistent, the spring 306 is released. The rebound force of the 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-pull shaft pin 307 gradually ends, and the rebound force of the top spring 306 is gradually released, pushing the positioning rod 305 downward 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 torsion brake is performed between the guide assembly 200 and the outer frame 100 again to ensure that the guide assembly 200 will not rotate at will during the power generation process, thereby ensuring the stability of the equipment operation.

[0039] Furthermore, a placement groove 2007 is provided inside the main wing 207, the auxiliary wing 302 is located inside the placement groove 2007, the gap between the outer wall of the auxiliary wing 302 and the inner wall of the placement groove 2007 is 0.3-0.5 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 wind guide cover 202, and the end of the push-pull shaft pin 307 abuts against the top of the cam strip 304;

[0040] By providing a placement groove 2007 inside the main wing 207, it is convenient to install the secondary wing 302, and at the same time, it is also prevented that the main wing 207 causes interference with the secondary wing 302. A gap of 0.3 to 0.5 cm is provided between the placement groove 2007 and the secondary wing 302 to ensure that during the rotation of the secondary wing 302, its edge will not come into contact with and interfere with the inner wall of the placement groove 2007, thereby ensuring smooth rotation of the secondary wing 302.

[0041] Furthermore, a limiting arc groove 308 is formed on one side of the cam strip 304 away from the push-pull shaft pin 307, a fixing plate 309 is fixedly mounted on the top wall of the top cover 206, a limiting rod 3010 is fixedly mounted on 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 bar 304 will drive the limiting arc groove 308 to rotate. Further, under the interference of the limiting rod 3010 on the limiting arc groove 308, the rotation angle of the cam bar 304 will not be too large, that is to say, the overall rotation angle of the connecting sleeve 303, the vertical shaft 301 and the secondary wing 302 will not be too large.

[0043] When a low wind speed power generation device of the present scheme is working, the device is assumed to be installed at the installation site through a stable bracket arranged at the bottom thereof, and the power generation output line end of the device is connected to the input end of the external power storage device. When in use, the external airflow passes through the dustproof net 700 to filter out particulate matter and dust, and then enters the interior of the wind guide cover 202. Due to the blocking of multiple partitions 203, the airflow entering the interior of the wind guide cover 202 is divided into multiple strands, which successively enter the interior of the cavity formed by the multiple partitions 203. Subsequently, the airflow is guided by multiple air distribution ports 204, which can optimize the airflow direction, so that the airflow can enter the interior of the air distribution port 204 more efficiently, and flow downward from the bottom of the air distribution port 204, causing a blowing effect on the blades 500, so that the blades 500 rotate and drive the shaft of the generator 400 to rotate, so that the generator 400 generates electricity and continuously transmits electric energy to the external power storage device.

[0044] During use, if the direction of the external airflow changes, the air flow 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 twisted toward the side with lower air pressure. Initially, due to the elastic force of the top spring 306, the positioning rod 305 is pressed downward, so that the bottom of the positioning rod 305 abuts against the top of the air outlet 101, producing a braking effect. Therefore, the turntable 201 will not rotate. If the turntable 201 does not rotate, it will act on the main wing through the top cover 206. The braking effect of 207 is eliminated, so the main wing 207 will not rotate. When the two sides of the main wing 207 are subjected to pressures of different magnitudes, the two sides of the auxiliary wing 302 are also subjected to pressures of different magnitudes, causing the auxiliary wing 302 to rotate to the side with less pressure inside the accommodating groove 2007. The rotation of the auxiliary wing 302 drives the connecting sleeve 303 and the cam bar 304 to rotate together through the connection effect of the vertical shaft 301. The rotation of the cam bar 304 drives the limiting arc groove 308 to rotate. Further, under the interference effect of the limiting rod 3010 on the limiting arc groove 308, The rotation angle of the cam strip 304 will not be too large. At the same time, the rotation of the connecting sleeve 303 also drives the reset swing arm 3011 to rotate together with the card slot 3012, causing the elastic strip 3013 to bend elastically, thereby storing energy for the rotation and reset of the connecting sleeve 303. At the same time, the rotation of the cam strip 304 will produce an upward thrust on the push-pull shaft pin 307, causing the positioning rod 305 to move upward, compressing the top spring 306 to produce an energy storage effect on the positioning rod 305 to reset downward, and the positioning rod 305 moves upward, and its bottom is directly separated from the top of the outer frame 100. In other words, the positioning rod 305 The braking effect between the insertion rod 305 and the outer frame 100 ends. At this time, the different wind pressures on both sides of the main wing 207 cause 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 wind guide cover 202, the partition 203 and the dust net 700 to rotate together through the top cover 206, so that after the wind direction changes, the air inlet end of the wind guide cover 202 always faces the wind direction. Therefore, when the wind direction changes, the power generation performance of the device will not be affected, ensuring the efficient output of electric energy and improving the power generation capacity;

[0045] When the wind pressure on both sides of the main wing 207 is consistent, the resilience of the elastic 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-pull shaft pin 307 gradually ends, and the resilience of the top spring 306 is gradually released, pushing the positioning rod 305 downward 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 torsion brake is performed between the guide assembly 200 and the outer frame 100 again to ensure that the guide assembly 200 will not rotate at will during the power generation process, thereby ensuring the stability of the equipment operation.

[0046] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
