Description

Technical Field

[0001] This application relates to the technical field of wind power generation equipment, and particularly to a universal wind-gathering floor-standing vertical-axis micro-wind generator based on the Venturi effect. Background Art

[0002] In a low-wind-speed environment, traditional vertical-axis micro-wind generators have limited wind energy capture ability, resulting in low power generation efficiency. For most conventionally designed wind turbine blades, the conversion of the acting force of gentle breeze is insufficient, and a large amount of wind energy is directly lost without being effectively utilized. Existing wind-gathering devices have poor effects on converging and guiding omnidirectional gentle breeze, and cannot make full use of weak airflows in different directions, resulting in large fluctuations in power generation efficiency in the case of variable wind directions.

[0003] Chinese Patent with the authorization announcement number CN103925150B discloses a universal wind-gathering floor-standing micro-wind generator based on the Venturi effect, which includes three parts: a wind power collection unit, a wind power acceleration unit, and an additional unit; the wind power collection unit consists of an inner wall surface, an outer wall surface that gradually shrinks along the flow channel, and a partition between them; the wind power acceleration unit consists of a wind power transition pipe, a Venturi tube, and a diffuser tube; the additional unit includes a power generation unit, an external support, a one-way door wind shielding device, and a wind speed measuring device.

[0004] However, there are still some problems with this patent: when the device is in use, the rotation speed of the wind power collection unit is accelerated through the Venturi effect. However, when the natural wind outside is strong, further strengthening the wind will further accelerate the rotation speed of the wind power collection unit, easily causing damage due to rotational speed overload. Summary of the Invention

[0018] Advantages of the present application: Through the design of the wind transition channel and the Venturi tube, the present application can capture wind from any direction and accelerate the wind. A monitoring component is set to detect the rotation speed of the fan.

The rotation speed of the connecting ring is much lower than that of the fan. Through the multi-stage transmission structure, the rotation speed of the turbine fan blades will not be the same as that of the fan, preventing the turbine fan blades and the fan blades from being damaged due to overloaded rotation speed under the drive of strong natural wind from the outside, further protecting components such as the turbine fan blades and the fan blades. By utilizing the cooperation between components such as the fan inner strut, friction block, movable sleeve, and connecting ring, the automatic adjustment of the transmission relationship according to the magnitude of the external wind force is achieved.

Detailed implementation manners

[0033] To make the above objects, features, and advantages of this application more apparent and understandable, the following will provide a detailed description of the specific implementation manners of this application with reference to the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth to facilitate a thorough understanding of this application. However, this application can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of this application. Therefore, this application is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of this application. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive with other embodiments.

[0036] Embodiment 1

[0037] This is the first embodiment of this application, which provides a universal wind-gathering floor-standing vertical-axis micro-wind generator based on the Venturi effect.

[0038] Specifically, referring to Figures 1 to 3 , Figure 6 and Figure 7 , the main body component 100 includes a bracket 101, a chamber 102 provided at the end of the bracket 101, a turbine fan blade 103 provided at the end of the chamber 102, and fan blades 105 arranged in an array on the outer wall of the turbine fan blade 103;

[0039] The adjustment component 200 provided at the end of the turbine fan blade 103 includes a wind transition channel 201, an inner partition 202 provided inside the wind transition channel 201, and a Venturi tube 203 provided at the end of the wind transition channel 201;

[0040] A fan 301 is provided on the inner wall of the Venturi tube 203. A control component and a connection component are further provided on the inner wall of the fan 301. The connection component is connected to the turbine fan blade 103. When the fan 301 rotates, the control component on the inner wall cooperates with the connection component to drive the turbine fan blade 103 to rotate at the end of the chamber 102. A monitoring component is further provided inside the Venturi tube 203 to detect the rotation speed of the fan 301. When the rotation speed of the fan 301 exceeds a preset threshold, the control component is separated from the connection component, and at the same time, the rotation speed of the turbine fan blade 103 is slowed down by electromagnetic braking inside the chamber 102.

[0041] Among them, the turbine fan blade 103 and the fan blades 105 are connected together and rotate together at the end of the chamber 102. Power is generated by the rotation of the turbine fan blade 103 and the fan blades 105. The power generation component is installed inside the chamber 102. At the same time, a wind transition channel 201 is installed at the top of the turbine fan blade 103. The inside of the wind transition channel 201 is divided into multiple wind channels by the inner partition 202. The wind transition channel 201 can capture wind from any direction and transport it into the wind channels. After the wind passes through the Venturi tube 203 at the bottom, the flow rate of the wind will increase. At this time, the fan 301 inside will rotate under the blowing of the wind with increased flow rate.

[0042] When the fan 301 rotates, the control component inside the fan 301 cooperates with the connection component to drive the turbine fan blade 103 to rotate together for power generation. When the external wind speed is low, the wind speed is increased by the Venturi tube 203 to drive the turbine fan blade 103 and the fan blades 105 to rotate for power generation. Due to the acceleration by the Venturi tube 203, the rotation speed of the fan 301 inside is greater than that of the external turbine fan blade 103. The rotation speed of the fan 301 is measured by the monitoring component. When the rotation speed of the fan 301 reaches the threshold at which the turbine fan blade 103 may be damaged, the rotation speeds of the turbine fan blade 103 and the fan blades 105 are slowed down by electromagnetic braking to avoid damage to the generator when the external wind force is large.

[0043] Embodiment 2

[0044] This is the second embodiment of the present application, which is implemented based on the previous embodiment.

[0045] Specifically, referring to Figures 2 to 6 , a plurality of inner partition plates 202 are arrayed and fixed to the inner wall of the wind transition channel 201. Wind channels are formed between adjacent inner partition plates 202. After the wind enters the wind channels, the wind speed is increased after passing through the Venturi tubes 203 at the bottom of the inner partition plates 202.

[0046] Among them, the wind transition channel 201 can capture the wind from any direction outside and form a wind channel between two adjacent inner partition plates 202 for the outside wind to enter the interior. When passing through the Venturi tubes 203 below, the wind speed is significantly increased compared to the outside wind speed.

[0047] Preferably, referring to Figures 6 to 9 , the fan 301 is installed at the end of the Venturi tube 203 and rotates driven by the wind. An inner lining plate 3011 is provided on the inner wall of the fan 301. The control component includes an inner support rod 302. The end of the inner support rod 302 is hinged to the outer wall of the inner lining plate 3011. A friction block 3021 is provided at the end of the inner support rod 302, and a convex block 3022 is further provided on the inner wall of the inner support rod 302. The end of the convex block 3022 is connected to a first elastic member 3023, and the other end of the first elastic member 3023 is connected to the outer wall of the inner lining plate 3011. The inner support rod 302 is pulled by the first elastic member 3023 to make the friction block 3021 at the end deflect inward.

[0048] Among them, a bearing seat is provided inside the fan 301 and is installed at the air outlet position at the lower end of the Venturi tube 203. At this time, the accelerated wind blows on the fan 301 to drive the fan 301 to rotate inside the Venturi tube 203. A plurality of inner support rods 302 are arrayed on the surface of the inner lining plate 3011 inside the fan 301. Each inner support rod 302 is equipped with a first elastic member 3023 to pull the inner support rod 302, so that the friction block 3021 at the other end of the inner support rod 302 moves closer to the inside.

[0049] When the rotation speed of the fan 301 is relatively low, at this time the inner support rod 302 is pulled by the first elastic member 3023, and the friction block 3021 at the other end moves towards the axis of the fan 301. When the rotation speed of the fan 301 increases, at this time the inner support rod 302 is affected by the centrifugal force, and the friction block 3021 at the top moves around and deviates from the axis of the fan 301.

[0050] Preferably, referring to Figures 1 to 11, a support column 1011 is fixed to the end of the bracket 101, and a movable sleeve 303 is movably arranged at the end of the support column 1011. A bearing seat is arranged on the inner wall of the movable sleeve 303 and connected to the support column 1011. The inner strut 302 on the inner wall of the fan 301 is pulled by the first elastic member 3023, and the friction block 3021 at the end fits against the outer wall of the movable sleeve 303. The movable sleeve 303 rotates with the fan 301 on the outer wall of the support column 1011.

[0051] Among them, the support column 1011 is fixed to the end of the bracket 101 and does not move. As Figure 1 shown, the chamber 102 is fixed above the bracket 101. At the same time, the support column 1011 penetrates through the chamber 102 and the turbine blade 103 and extends all the way to the top position of the wind transition channel 201. As Figure 11 shown, bearing seats are installed at the upper and lower ends of the movable sleeve 303, and the movable sleeve 303 is installed outside the support column 1011. Therefore, the movable sleeve 303 can rotate outside the support column 1011.

[0052] The installation position of the fan 301 is slightly higher than that of the movable sleeve 303. The inner lining plate 3011 inside the fan 301 is flush with the top position of the movable sleeve 303. Therefore, when the rotation speed of the fan 301 is low, the inner strut 302 inside is pulled by the first elastic member 3023, and the friction block 3021 at the other end fits inward against the outside of the movable sleeve 303. Through the cooperation of multiple inner struts 302, when the fan 301 rotates, it drives the movable sleeve 303 to rotate with the fan 301 outside the support column 1011.

[0053] In summary, during use, when the external wind force is small, the external natural wind alone cannot drive the turbine blade 103 and the blade 105 to rotate for power generation. The natural wind from the outside is captured through the wind transition channel 201 at the top, and the wind flowing through is accelerated through the Venturi tube 203 below, blowing the internal fan 301 to rotate. When the external wind force is low, the rotation speed of the fan 301 is also limited. At this time, the rotation speed of the fan 301 is low. The inner strut 302 inside the fan 301 is pulled by the first elastic member 3023, and the friction block 3021 at the other end moves inward and adheres to the outside of the movable sleeve 303, driving the movable sleeve 303 to rotate with the fan 301. When the external wind force is large, the wind force after being accelerated by the Venturi tube 203 is stronger than the external natural wind at this time. The rotation speed of the internal fan 301 further increases. After the centrifugal force increases, the friction block 3021 at the end of the inner strut 302 deflects outward under the influence of the centrifugal force and disengages from the outer wall of the movable sleeve 303. At this time, the rotation of the fan 301 does not drive the rotation of the movable sleeve 303.

[0054] Embodiment 3

[0055] This is the third embodiment of the present application, which is implemented based on the previous embodiment.

[0056] Specifically, referring to Figure 10 and Figure 11 A connecting ring 304 is sleeved on the end of the movable sleeve 303. A plurality of air-dispersing through holes 3042 are formed on the end face of the connecting ring 304 for air delivery. An activity ring 305 is further arranged at the end of the connecting ring 304, and the activity ring 305 is sleeved on the outer wall of the movable sleeve 303. An activity column 3051 is arranged on the outer wall of the activity ring 305, and the end of the activity column 3051 extends to the inner wall of the connecting ring 304. A moving part is further arranged at the end of the activity ring 305, and the moving part cooperates with the activity ring 305 to drive the connecting ring 304 to rotate.

[0057] Among them, the connecting ring 304 is sleeved outside the movable sleeve 303 and is not fixed to the movable sleeve 303. The air-dispersing through holes 3042 on the surface are used to convey the air accelerated by the Venturi tube 203 to move downward.

[0058] The activity ring 305 is sleeved outside the movable sleeve 303, is not fixed to the movable sleeve 303 and is on the upper surface of the connecting ring 304. Through the cooperation of the moving part with the activity ring 305 and the activity column 3051, the connecting ring 304 is driven to rotate outside the movable sleeve 303 following the movable sleeve 303, but the rotation speed of the connecting ring 304 is not the same as that of the movable sleeve 303.

[0059] Preferably, referring to Figure 10 and Figure 11 The moving part includes a cam 306, and the cam 306 is fixed to the outer wall of the movable sleeve 303 and rotates with the movable sleeve 303. A moving ring 307 is movably sleeved on the outer wall of the cam 306. A first straight rod 3071 is arranged on the outer wall of the moving ring 307, and a first movable block 3072 is movably arranged at the end of the first straight rod 3071. The end of the first movable block 3072 extends to the inner wall of the end of the activity column 3051 and is slidably matched with it. A second straight rod 3073 is further arranged at the other end of the moving ring 307, and a second movable block 3074 is arranged at the end of the second straight rod 3073. A fixed ring 308 is further arranged at the end of the moving ring 307, and a fixed rod 3081 is arranged on the outer wall of the fixed ring 308. The fixed rod 3081 is attached to the outer wall of the second movable block 3074.

[0060] Among them, the cam 306 is fixed to the outer wall of the movable sleeve 303, synchronously follows the movable sleeve 303 and is above the activity ring 305. A moving ring 307 is sleeved outside the cam 306, but the moving ring 307 is not fixed to the cam 306. When the cam 306 follows the movable sleeve 303 to rotate, the cam 306 rotates inside the moving ring 307 to drive the moving ring 307 to move.

[0061] Above the moving ring 307, there is a fixed ring 308 which is fixed to the inner wall of the Venturi tube 203 and is not affected by the rotation of the movable sleeve 303. The fixed ring 308 remains stationary. At the same time, the fixing rod 3081 on the outer wall of the fixed ring 308 is outside the second movable block 3074 at the end of the second straight rod 3073. Through the fixing of the fixing rod 3081, the second movable block 3074 only moves back and forth inside the inner wall of the fixing rod 3081. At the same time, the first straight rod 3071 and the first movable block 3072 at the other end of the moving ring 307 will perform a cyclic deflection motion.

[0062] The inner wall of the connecting ring 304 is provided with a groove 3041 which cooperates with the first movable block 3072 and the second movable block 3074. The end of the connecting ring 304 is also provided with a connecting sleeve 3043. The end of the connecting sleeve 3043 is sleeved on the outer wall of the connecting cylinder 1031 at the axis of the turbine fan blade 103. The connecting sleeve 3043 rotates on the outer wall of the connecting cylinder 1031 along with the connecting ring 304.

[0063] Among them, a plurality of grooves 3041 are arrayed on the inner wall of the connecting ring 304 and the grooves 3041 cooperate with the first movable block 3072 and the second movable block 3074. When the first movable block 3072 moves back and forth at the end of the fixing rod 3081, when the second movable block 3074 enters the current groove 3041, the first movable block 3072 is withdrawn from the groove 3041. And along with the rotation of the movable sleeve 303, after the first movable block 3072 is withdrawn from the groove 3041, it deflects with the second movable block 3074 as the fulcrum and enters the next groove 3041. That is, when the movable sleeve 303 rotates one circle, the connecting ring 304 rotates by the angle of one groove.

[0064] Refer to Figure 9 , a first meshing ring 1032 is fixed to the end of the connecting cylinder 1031. A second meshing ring 3045 which cooperates with the first meshing ring 1032 is arranged on the inner wall of the connecting sleeve 3043. The meshing of the second meshing ring 3045 and the first meshing ring 1032 drives the turbine fan blade 103 to rotate on the outer wall of the support column 1011.

[0065] Among them, the first meshing ring 1032 at the top of the connecting cylinder 1031 meshes with the second meshing ring 3045 inside the connecting sleeve 3043. Through the meshing of the first meshing ring 1032 and the second meshing ring 3045, the connecting cylinder 1031 and the connecting ring 304 rotate synchronously, driving the turbine fan blade 103 to rotate outside the support column 1011.

[0066] The rotational speed of the connecting ring 304 is much lower than that of the fan 301, which is used to protect the external turbine blades 103 and blades 105. The rotational speed of the fan 301 is affected by the wind force inside the venturi tube 203 and is much higher than the rotational speed under normal wind speed. If the rotational speed of the turbine blade 103 is the same as that of the fan 301, the turbine blade 103 and the blade 105 are likely to have an overload in rotational speed and be damaged under the drive of a strong external natural wind.

[0067] Refer to Figure 9 , the outer wall of the second engaging ring 3045 is provided with sliders 3046 arrayed thereon, and the end of the slider 3046 extends to the inner wall of the slideway 3044 opened on the inner wall of the connecting sleeve 3043. The second engaging ring 3045 is restricted by the slideway 3044 and cannot rotate. A second elastic member 3047 is further provided at the end of the second engaging ring 3045, and the second elastic member 3047 pushes the second engaging ring 3045 downward to engage with the first engaging ring 1032.

[0068] Among them, the second engaging ring 3045 slides in the slideway 3044 through the sliders 3046 on the outer wall to restrict the second engaging ring 3045. The second engaging ring 3045 can only move linearly inside the connecting sleeve 3043. The second elastic member 3047 pushes the second engaging ring 3045 downward to engage with the first engaging ring 1032, so that the connecting ring 304 drives the connecting cylinder 1031 to rotate outside the support column 1011.

[0069] When the rotational speed of the turbine blade 103 driven by the external natural wind is lower than the rotational speed of the connecting ring 304, at this time, the second elastic member 3047 pushes the second engaging ring 3045 downward to engage with the first engaging ring 1032, driving the turbine blade 103 to rotate at a rotational speed higher than that under normal wind speed. When the rotational speed of the turbine blade 103 driven by the external natural wind is higher than the rotational speed of the connecting ring 304, at this time, the rotational speed of the connecting cylinder 1031 is higher than the rotational speed of the connecting ring 304, and the first engaging ring 1032 will push the second engaging ring 3045 upward.

[0070] Preferably, refer to Figures 2 to 5 , an installation column 1012 is further sleeved on the outer wall of the support column 1011. The turbine blade 103 is fixed to the outer wall of the installation column 1012. When the turbine blade 103 rotates, it drives the installation column 1012 to rotate on the outer wall of the support column 1011. An air-dispersing duct 106 is provided inside the turbine blade 103, and the end of the air-dispersing duct 106 extends to the outer wall of the blade 105. After the wind force drives the fan 301 to rotate through the venturi tube 203, it is discharged through the air-dispersing duct 106. Connecting frames 104 are arrayed on the outer wall of the turbine blade 103 for fixing the blade 105.

[0071] Among them, the installation column 1012 is sleeved outside the support column 1011. The support column 1011 is fixed above the bracket 101 and does not rotate, while the installation column 1012 can rotate outside the support column 1011. At the same time, the connecting cylinder 1031 at the axis of the turbine fan blade 103 is fixed outside the installation column 1012. The turbine fan blade 103 and the fan blade 105 are fixedly combined into one through the connecting frame 104. When the turbine fan blade 103 rotates, it drives the installation column 1012 to rotate together. The bottom of the installation column 1012 rotates synchronously inside the chamber 102 to generate electricity.

[0072] In summary, during use, the natural wind from the outside is accelerated by the Venturi tube 203 and then blows the fan 301 to rotate. The fan 301 rotates inside the Venturi tube 203. When the natural wind speed outside is low, the accelerated wind blows the fan 301 to rotate. At this time, the friction block 3021 at the end of the inner support rod 302 at the bottom of the fan 301 drives the movable sleeve 303 to rotate. When the movable sleeve 303 rotates, it drives the connecting ring 304 to rotate together through the cooperation of the moving parts on the surface of the connecting ring 304 with the movable ring 305 and the movable column 3051. The rotation speed of the connecting ring 304 is lower than that of the movable sleeve 303. At this time, the second engagement ring 3045 inside the connecting sleeve 3043 below the connecting ring 304 is pushed by the second elastic member 3047 to engage with the first engagement ring 1032 at the end of the connecting cylinder 1031 and drives the external turbine fan blade 103 and the fan blade 105 to rotate. The installation column 1012 rotates inside the chamber 102 together with the rotation of the turbine fan blade 103 to generate electricity.

[0073] When the natural wind force from the outside becomes stronger, the rotation speed of the fan 301 inside the Venturi tube 203 further increases. At this time, under the action of centrifugal force, the inner support rod 302 at the bottom of the fan 301 causes the friction block 3021 to disengage from the movable sleeve 303. At this time, the rotation of the fan 301 no longer drives the movable sleeve 303 to rotate, but the rotation speed of the fan 301 is still being monitored. Since the rotation speed of the fan 301 is higher than that of the external turbine fan blade 103, when the rotation speed of the fan 301 reaches the rotation speed threshold of the turbine fan blade 103, in order to prevent subsequent wind force from continuing to increase and damaging the turbine fan blade 103 and the fan blade 105, the rotation speed of the turbine fan blade 103 will be slowed down by means of electromagnetic braking to avoid speed overload.

[0074] Since the rotational speed of the connecting ring 304 is lower than that of the fan 301, when the rotational speed of the turbine fan blade 103 driven by the natural wind from the outside is lower than that of the connecting ring 304, the second engagement ring 3045 on the lower surface of the connecting ring 304 meshes with the first engagement ring 1032 at this time, and the rotation of the turbine fan blade 103 is driven by the connecting ring 304. When the rotational speed of the turbine fan blade 103 driven by the natural wind from the outside is higher than that of the connecting ring 304, the rotation of the second engagement ring 3045 relative to the first engagement ring 1032 is in a relatively static state at this time, and the rotation of the first engagement ring 1032 will push the second engagement ring 3045 to move it upward, reducing the influence of the second engagement ring 3045 on the rotation of the connecting cylinder 1031 and ensuring the rotation of the turbine fan blade 103.
