Description

Technical Field

[0001] The invention relates to the technical field of wind-driven vibration power generation equipment, and mainly to a swing-type power generation windmill. Background Art

[0002] The swing-type windmill is a device that uses wind vibration to generate electricity. The micro-swing windmill unit has the following advantages: 1. It can efficiently utilize low-speed wind power; 2. It can generate electricity even when the wind direction changes, and it can adapt to highly complex environments; 3. The generator can be placed on the ground, which is easy to construct and maintain; 4. The small size has less impact on the ecological environment; 4. There is no need to raise the tower, and the small body has a high degree of assembly. For example, the patent application with publication number KR1020180106569A discloses a swing-type windmill.

[0003] However, the oscillating wind turbine in the prior art is connected to the wind in the environment only through the vibrating column, and the swept wind area of ​​the oscillating wind turbine cannot be changed. The above-mentioned swept wind area refers to the area of ​​the wind that the oscillating wind turbine can contact. The larger the swept wind area, the greater the wind force the wind turbine is subjected to, the greater the swing amplitude and the faster the swing speed of the vibrating column, and the higher the power generated by the equipment. Since the swept wind area of ​​the oscillating wind turbine in the prior art cannot be changed, when the ambient wind speed is greater than the working range of the oscillating wind turbine, the excessive swing amplitude of the vibrating column may damage the equipment; in addition, when the ambient wind speed is relatively low, since the swept wind area of ​​the existing oscillating wind turbine cannot be increased, it will also affect the power generation efficiency of the generator, resulting in the existing oscillating wind turbine being unable to capture wind energy in low wind speed environments, the scope of wind energy utilization is small, and there is a problem that it cannot be adapted to areas with weaker wind resources.

[0004] Therefore, those skilled in the art hope to solve the current situation that the wind sweeping area of ​​the existing swing-type power-generating wind turbine cannot be changed, so as to effectively ensure the equipment safety and wind energy capture capability of the swing-type power-generating wind turbine.

[0031] The technical solution of the present invention has the following advantages:

[0032] 1. The swing-type power generation windmill provided by the present invention comprises:

[0033] A wind catcher, comprising: at least two fan-shaped blades connected in cooperation; the wind catcher has an unfolded state driven to be opened, and a folded state driven to be closed;

[0034] A vibrating column, wherein the wind catcher is arranged at the upper end of the vibrating column, and the vibrating column generates oscillation and swinging under the driving force of wind, converting wind energy into kinetic energy, and transmitting it to the rotor through a mechanical transmission device, and then the generator converts the kinetic energy into electrical energy;

[0035] A wind speed sensor is used to monitor the wind speed at the position of the wind catcher, and is communicated with the wind catcher through a controller to control the wind catcher to switch between the folded state and the unfolded state; when the wind speed sensor detects that the wind speed is within the working range of the wind catcher, the wind catcher switches to the unfolded state to form a large fan to capture wind energy; when the wind speed sensor detects that the wind speed is less than or greater than the working range of the wind catcher, the wind catcher switches to the folded state.

[0036] In the present invention, the swing-type power-generating windmill has a wind-catching head that can be driven to actively unfold and fold. When the wind speed sensor detects that the wind speed is within a suitable range, the fan-shaped blades of the wind-catching head unfold and increase the wind-swept area, so that the swing-type power-generating windmill can effectively obtain wind energy, making it suitable for areas with weaker wind resources, realizing low-wind-speed wind energy capture, and expanding the scope of wind energy utilization. At the same time, when the wind force is strong, the controller controls the wind-catching head to switch to a folded state to reduce the wind-swept area of ​​the swing-type power-generating windmill, thereby preventing the problem of excessive wind force and damage to the power generation equipment. Moreover, in the present invention, the wind-swept area is changed by controlling a plurality of coordinated and connected fan-shaped blades to unfold and fold. The above structure has the advantages of being simple, reliable, and easy to control.

[0037] 2. The swing-type power generation windmill provided by the present invention further comprises:

[0038] A wind direction sensor, used to monitor the wind direction at the wind catcher position;

[0039] The wind catcher is rotatably hingedly connected to the vibration column via a driving shaft, and the controller is communicatively connected to the wind direction sensor to control the wind catcher to rotate along the circumferential direction of the vibration column and adjust the direction of the wind catcher;

[0040] The controller adjusts the angle of the wind catcher according to the wind speed and wind direction data to improve the wind catching effect.

[0041] In the present invention, by providing a wind direction sensor and cooperating with the driving shaft for connecting the wind catcher and the vibration column, it can be effectively realized that: the wind direction change in the environment is detected by the wind direction sensor, and the orientation position of the wind catcher is adjusted as needed, so that the wind catcher is directed to the incoming wind direction and the power generation efficiency is improved.

[0042] 3. The swing-type power generation windmill provided by the present invention has a driving shaft comprising:

[0043] The connecting sleeve is a hard structure, one end of which is fixedly connected to the wind catcher, and the other end of which is rotatably connected to the vibration column;

[0044] A driving rod, on which a rotating tooth is arranged; the rotating tooth is connected to the driving tooth and is driven to drive the driving rod to rotate along its circumferential direction;

[0045] The connecting wing is fixedly arranged on the driving rod and is fixedly connected to the inner cavity wall of the connecting sleeve.

[0046] In the present invention, the vibration column is rotatably connected to the wind catcher through the connecting sleeve, thereby effectively realizing the circumferential rotation position of the wind catcher relative to the vibration column. In addition, the driving rod is arranged at the connection position between the connecting sleeve and the vibration column, and the connecting sleeve and the wind catcher fixedly connected to the connecting sleeve can be effectively driven to rotate by driving the driving rod to rotate synchronously. The above structure has the advantages of stable and reliable structure.

[0047] 4. The swing-type power-generating windmill provided by the present invention has at least two groups of connecting wings arranged in the length direction of the driving rod; an arc-shaped connecting plate rotatably connected thereto is also arranged between two adjacent groups of connecting wings, and the arc-shaped connecting plate is adapted to the shape of the inner cavity wall of the connecting sleeve and is fixedly connected to the connecting sleeve.

[0048] In the present invention, by providing at least two sets of connecting wings, and allowing the connecting wings to be fixedly connected to the inner cavity wall of the connecting sleeve through the arc-shaped connecting plate, the connecting surface between the arc-shaped connecting plate and the connecting sleeve can be effectively increased, thereby ensuring the connection strength between the two. Furthermore, the arc-shaped connecting plate is rotatably arranged on the connecting wing, which can effectively facilitate the operator to adjust the inclination angle of the arc-shaped connecting plate, thereby reducing the difficulty of connecting the arc-shaped connecting plate to the inner cavity wall of the connecting sleeve, and facilitating the installation and maintenance of the equipment.

[0049] 5. The swing-type power-generating windmill provided by the present invention also includes: a driving motor, and a vibration column accommodating cavity is provided at one end of the vibration column close to the connecting sleeve; the driving motor is arranged in the vibration column accommodating cavity, and is connected to the rotating teeth on the driving rod through the driving teeth.

[0050] In the present invention, a vibration column accommodating chamber is provided at one end of the vibration column close to the connecting sleeve, and other parts of the vibration column are provided as a solid elastic structure according to the needs of the vibration column. The above-mentioned vibration column accommodating chamber can be provided with a driving motor as required, and the driving motor is connected to the rotating gear through the driving teeth to drive the driving rod to rotate so as to adjust the direction of the wind catcher. The above-mentioned structure is not only stable and reliable, but also the arrangement of the driving motor at the top of the vibration column can also increase the swing amplitude of the vibration column when the wind catcher drives the vibration column to swing, thereby improving the power generation effect.

[0051] 6. In the swing-type power generation windmill provided by the present invention, the fan-shaped blades are hollow bladder structures made of polymer membrane materials, and the fan-shaped blades are connected to the inflation mechanism;

[0052] The outer contour edge of the fan-shaped blade is also provided with a frame for maintaining the fan-shaped blade in a stored shape; when the fan-shaped blade is inflated, the air pressure overcomes the elastic force of the frame to switch the fan-shaped blade to the expanded state;

[0053] The skeletons at the edge positions of the adjacent fan-shaped blades are connected by hinges, so that the wind catcher forms a rod-shaped structure in the folded state and reduces wind resistance; the two adjacent blades of the hinge are magnetic parts that attract each other or elastic parts that attract each other; when the fan-shaped blades are inflated, the adjacent fan-shaped blades overcome the driving force of the hinge to fold, so that the adjacent fan-shaped blades can be unfolded; when the fan-shaped blades are deflated, the magnetic force or elastic force of the hinge drives the hinge to close, so that the wind catcher can be folded.

[0054] In the present invention, the fan-shaped blade is provided as a membrane structure blade having a hollow airbag structure, and a frame is provided at the outer contour edge of the fan-shaped blade. When the inflation mechanism inflates the airbag of the fan-shaped blade, the fan-shaped blade expands rapidly, overcomes the elastic force of the frame, and forms a connection surface with the wind. In addition, when the fan-shaped blade is deflated, the wind catcher can be automatically folded under the action of the elastic driving force of the frame.

[0055] In addition, the skeletons at the edge positions of the adjacent fan-shaped blades are connected by hinges, so that the wind catcher forms a rod-shaped structure in the folded state and reduces wind resistance. The two blades of the hinge are set as magnetic parts that attract each other or elastic parts that attract each other. When the fan-shaped blades are inflated, the adjacent fan-shaped blades overcome the driving force of the hinge folding to achieve the unfolding of the adjacent fan-shaped blades. When the fan-shaped blades are deflated, the magnetic force or elastic force of the hinge drives the hinge to close, so that the wind catcher can be folded and wind resistance can be reduced. The above structure has the advantages of simple and reliable structure.

[0056] 7. In the swing-type power-generating windmill provided by the present invention, the wind speed sensor and the wind direction sensor are accommodated in a sensor module of a columnar structure; the sensor module is arranged in the middle of the wind catcher, and the fan-shaped blades are driven to fold toward the sensor module to achieve closure.

[0057] In the present invention, the wind speed sensor and the wind direction sensor are integrated into one sensor module. The sensor module is set as a columnar structure, installed in the middle of the wind catcher and arranged along the extension direction of the wind catcher. Adjacent sensor modules and fan-shaped blades are then connected together by hinges. The sensor arrangement method can make the sensor closer to the wind catcher to ensure the accuracy of data collection. In addition, the fan-shaped blades on the left and right sides of the wind catcher can be separated, and the fan-shaped blades on both sides of the wind catcher can be folded toward the central position, so that the folded wind catcher is in the extension direction of the vibration column to ensure the stability of the device structure.

[0058] 8. The swing-type power generation windmill provided by the present invention, the airbag structure of the fan-shaped blades comprises: an airbag outer cavity wall and a partition layer arranged in the airbag outer cavity wall; the partition layer divides the space in the airbag outer cavity wall into at least two independent inflation cavities;

[0059] The partition layer is made of an elastic metal material with a hardness greater than that of the outer cavity wall of the airbag; when the fan-shaped blade is inflated, the air pressure value in the inflation cavity formed by the outer cavity wall of the airbag and the partition layer is greater than the air pressure value in the inflation cavity formed by the partition layer.

[0060] In the present invention, a partition layer is provided in the outer cavity wall of the airbag, and the partition layer is provided with an elastic metal material with relatively high hardness. When the wind catcher is in the unfolded state, the partition layer of the elastic metal material can effectively increase the structural strength of the wind catcher, thereby reducing the deformation of the wind catcher during the wind-catching process and ensuring the power generation effect. In addition, since the partition layer will be elastically deformed and store elastic force when it is stretched open by the gas, during the deflation process of the wind catcher, the elastic force of the partition layer drives the fan-shaped blades to fold back, thereby helping the wind catcher to be miniaturized during the folding process.

[0061] 9. In the swing-type power-generating windmill provided by the present invention, the airbag structure of the fan-shaped blades is connected to an inflation mechanism; the inflation mechanism is provided with inflation valves independently connected to the two inflation chambers; the inflation mechanism is arranged in the connecting sleeve.

[0062] In the present invention, by arranging the inflation mechanism in the connecting sleeve, the spatial layout of the swing-type power generation wind turbine can be effectively optimized. Moreover, since the connecting sleeve is a hard structure, the installation and fixing of the inflation mechanism is also convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Generator 11 and energy storage device, such as Figure 2 As shown, the generator 11 is located at the bottom of the vibration column 3, and the vibration and swing are transmitted to the generator 11 through the flexible transmission of the vibration column 3; the generator 11 has a coil and a magnet, and the vibration column 3 drives the coil and the magnet to move relative to each other during the swing process to cut the magnetic lines of force, generating an induced current that passes through the rectifier and is stored in the energy storage device;

[0080] Sensor module 13, such as Figure 4 As shown, the wind speed sensor and the wind direction sensor are accommodated in a sensor module 13 of a columnar structure; the sensor module 13 is arranged in the middle of the wind catcher 1, and the fan-shaped blades 2 are driven to fold toward the sensor module 13 to achieve closure. The wind speed sensor is used to monitor the wind speed at the position of the wind catcher 1, and is connected to the wind catcher 1 through a controller to control the wind catcher 1 to switch between the folded state and the unfolded state; when the wind speed sensor detects that the wind speed is in the working range of the wind catcher 1, the wind catcher 1 switches to the unfolded state to form a large fan surface to capture wind energy; when the wind speed sensor detects that the wind speed is less than or greater than the working range of the wind catcher 1, the wind catcher 1 switches to the folded state. The wind direction sensor is used to monitor the wind direction at the position of the wind catcher 1.

[0081] In this embodiment, see Figure 5 , Figure 5The schematic diagram of the internal structure of the driving shaft in the embodiment of the present invention is shown. The wind catcher 1 is connected to the vibration column 3 by a driving shaft 4, and the controller is connected to the wind direction sensor to control the wind catcher 1 to rotate along the circumferential direction of the vibration column 3 and adjust the direction of the wind catcher 1; the controller adjusts the angle of the wind catcher 1 according to the wind speed and wind direction data to improve the wind catching effect. Figure 5 As shown, the driving shaft 4 includes:

[0082] The connecting sleeve 5 is a hard structure, one end of which is fixedly connected to the wind catcher 1, and the other end of which is rotatably connected to the vibration column 3;

[0083] A driving rod 6, on which a rotating tooth 7 is provided; the rotating tooth 7 is connected to the driving tooth and is driven to drive the driving rod 6 to rotate along its circumferential direction;

[0084] The connecting wing 8 is fixedly arranged on the driving rod 6 and is fixedly connected to the inner cavity wall of the connecting sleeve 5. Moreover, at least two groups of the connecting wings 8 are arranged in the length direction of the driving rod 6; an arc-shaped connecting plate 9 rotatably connected thereto is also arranged between two adjacent groups of the connecting wings 8, and the arc-shaped connecting plate 9 is adapted to the shape of the inner cavity wall of the connecting sleeve 5 and is fixedly connected to the connecting sleeve 5. The connection surface between the arc-shaped connecting plate 9 and the connecting sleeve 5 can be effectively enlarged, thereby ensuring the connection strength between the two. Moreover, the arc-shaped connecting plate 9 is rotatably arranged on the connecting wing 8, which can effectively facilitate the operator to adjust the inclination angle of the arc-shaped connecting plate 9, thereby reducing the difficulty of connecting the arc-shaped connecting plate 9 with the inner cavity wall of the connecting sleeve 5, and facilitating the installation and maintenance of the equipment.

[0085] In this embodiment, see Figure 2 and Figure 5 As shown, the swing-type power generation windmill also includes:

[0086] The driving motor is provided with a vibration column accommodating cavity 10 at one end of the vibration column 3 close to the connecting sleeve 5; the driving motor is arranged in the vibration column accommodating cavity 10 and is connected to the rotating teeth 7 on the driving rod 6 through the driving teeth. The above structure is not only stable and reliable, but also the arrangement of the driving motor at the top of the vibration column 3 can also increase the swing amplitude of the vibration column 3 when the wind catcher 1 drives the vibration column 3 to swing, so as to improve the power generation effect.

[0087] In this embodiment, see Figure 2 and Figure 4 , Figure 2 A schematic diagram of the three-dimensional structure of a swing-type power generation wind turbine in an embodiment of the present invention is shown. Figure 4 An enlarged schematic diagram of the wind catcher structure in an embodiment of the present invention is shown.

[0088] The fan-shaped blade 2 is a hollow balloon structure made of polymer film material, and the fan-shaped blade 2 is connected to the inflation mechanism; the balloon structure of the fan-shaped blade 2 is connected to the inflation mechanism 16; the inflation mechanism 16 is provided with inflation valves 17 that are independently connected to the two inflation chambers; the inflation mechanism 16 is arranged in the connecting sleeve 5. The outer contour edge of the fan-shaped blade 2 is also provided with a skeleton that maintains the fan-shaped blade 2 in a stored shape; when the fan-shaped blade 2 is inflated, the air pressure overcomes the elastic force of the skeleton to switch the fan-shaped blade 2 to the expanded state;

[0089] Moreover, the skeletons at the edge positions of the adjacent fan-shaped blades 2 are connected by hinges 12, so that the wind catcher 1 forms a rod-shaped structure in the folded state and reduces wind resistance; the two adjacent blades of the hinge 12 are magnetic parts that attract each other; when the fan-shaped blades 2 are inflated, the adjacent fan-shaped blades 2 overcome the driving force of the hinge 12 to fold, so that the adjacent fan-shaped blades 2 are unfolded; when the fan-shaped blades 2 are deflated, the magnetic force of the hinge 12 drives the hinge 12 to close, so that the wind catcher 1 can be folded.

[0090] Furthermore, in this embodiment, if Figure 6 As shown, the airbag structure of the fan-shaped blade 2 includes: an airbag outer cavity wall 14 and a partition layer 15 arranged in the airbag outer cavity wall 14; the partition layer 15 divides the space in the airbag outer cavity wall 14 into at least two independent inflation cavities;

[0091] The partition layer 15 is made of an elastic metal material with a hardness greater than that of the airbag outer cavity wall 14 ; when the fan-shaped blade 2 is inflated, the air pressure value in the inflation cavity formed by the airbag outer cavity wall 14 and the partition layer 15 is greater than the air pressure value in the inflation cavity formed by the partition layer 15 .

[0092] When the wind catcher 1 is in the unfolded state, the partition layer 15 made of the elastic metal material can effectively increase the structural strength of the wind catcher 1, thereby reducing the deformation of the wind catcher 1 during the wind-catching process and ensuring the power generation effect. In addition, since the partition layer 15 will be elastically deformed and store elastic force when it is stretched open by the gas, during the deflation process of the wind catcher 1, the elastic force of the partition layer 15 drives the fan-shaped blades 2 to fold, helping the wind catcher 1 to be miniaturized during the folding process.

[0093] Of course, the present invention does not impose any specific restrictions on the location and manner of setting the sensor module 13. In other embodiments, the wind speed sensor and the wind direction sensor may also be set at other locations of the swing-type wind turbine. Alternatively, the sensor module 13 integrating the wind speed sensor and the wind direction sensor may also be set at the base of the swing-type wind turbine.

[0094] Of course, the present invention does not impose any specific restriction on whether the wind catcher 1 can achieve directional rotation. In other embodiments, the wind catcher 1 is directly fixedly connected to the vibration column 3, and the above-mentioned driving shaft 4 is not provided between the wind catcher 1 and the vibration column 3.

[0095] Of course, the present invention does not impose any specific restrictions on the connection method between the driving rod 6 and the connecting sleeve 5. In other embodiments, the connecting wing 8 is directly fixedly connected to the inner cavity wall of the connecting sleeve 5 without passing through the arc-shaped connecting plate 9.

[0096] Of course, the present invention does not impose any specific limitation on the manner in which two adjacent blades of the hinge 12 attract each other. In other embodiments, the two adjacent blades of the hinge 12 are elastic members that attract each other; when the fan-shaped blades 2 are inflated, the adjacent fan-shaped blades 2 overcome the driving force of the hinge 12 to fold, thereby achieving the unfolding of the adjacent fan-shaped blades 2; when the fan-shaped blades 2 are deflated, the elastic force of the hinge 12 drives the hinge 12 to close, thereby achieving the folding action of the wind catcher 1.

[0097] Of course, the present invention does not impose any specific restrictions on the location of the inflation mechanism 16. In other embodiments, the inflation mechanism 16 can also be disposed at the base of the swing-type wind turbine and connected to the airbag of the fan-shaped blade 2 through a pipeline.

[0098] Of course, the present invention does not impose any specific limitation on the airbag structure of the fan-shaped blade 2. In other embodiments, the airbag structure of the fan-shaped blade 2 is a single-layer structure without the above-mentioned partition layer 15.
