[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] It should be noted that, in the description of this application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0038] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0039] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0040] In order to solve any of the technical problems raised in the above background technology, this application proposes an embodiment of a wind power generation device. Specifically, the wind power generation device includes a bracket 1, at least one substrate 2, at least one piezoelectric energy collection module 3 corresponding to the substrate 2, and at least one vibration component 4 corresponding to the substrate 2. Figure 1 or Figure 3As shown, each substrate 2 is provided on the bracket 1. In this embodiment, the connection method between the substrate 2 and the bracket 1 is not limited. For example, Figure 1 As shown, the base plate 2 and the bracket 1 are integrally formed; Figure 2 As shown, the base plate 2 and the bracket 1 are screwed together and fixed by fastening bolts 21; Figure 3 As shown, the substrate 2 is welded and fixed to the bracket 1. Figure 1 and Figure 3 As shown, each piezoelectric energy collection module 3 is disposed on a corresponding substrate 2. In this embodiment, a vibration component 4 is connected to the corresponding substrate 2, and the vibration component 4 can drive the corresponding substrate 2 to vibrate in the wind.

[0041] It is easy to understand that in this embodiment, the vibration component 4 can drive the corresponding substrate 2 to vibrate against the wind, and the vibrating substrate 2 can further drive the piezoelectric energy collection module 3 to vibrate; further, the vibrating piezoelectric energy collection module 3 can generate electricity. It should be clear that the piezoelectric energy collection module 3 is based on the principle of vibration power generation for the piezoelectric effect. The piezoelectric effect refers to the fact that when certain crystal materials are subjected to external forces, the internal positive and negative charges will move and rearrange, thereby generating an electric potential difference. This potential difference can generate current by connecting wires and external circuits, thereby converting mechanical energy into electrical energy. Power generation based on the piezoelectric effect is a mature technology and will not be elaborated on here.

[0042] In the embodiment of the present application, the substrate 2 may be an anti-glare board. Of course, the substrate 2 may also be other boards commonly used in highways or urban roads, such as billboards or signboards. That is to say, in the embodiment of the present application, there is no restriction on the application scenario of the wind power generation device, and it may be any application scenario that utilizes wind power with the help of piezoelectric effect to generate electricity. In the subsequent embodiments, in order to avoid redundancy, the wind power generation device proposed in the present application is described with the anti-glare board as the application scenario. This does not mean that the wind power generation device proposed in the embodiment of the present application is only suitable for anti-glare boards, and no further description will be given later.

[0043] It should be understood that, in the embodiments of the present application, based on the arrangement of the substrate, the piezoelectric energy harvesting module, and the vibration assembly, the anti-glare panel can generate electricity through the wind generated by the vehicle's movement or natural wind. During long-term use, the anti-glare panel will not experience a decrease in power generation efficiency due to excessive dust on the road, nor will it reflect light and affect the driver's vision. Compared to the production cost of photovoltaic panels, the production cost of the piezoelectric energy harvesting module is also relatively low, making it suitable for the application scenario of anti-glare panel power generation.

[0044] In the embodiment of the present application, the vibration component 4 can not only play the role of vibration, but also play the role of counterweight. Figure 4As shown, if the distance between the vibration component 4 and the bracket 1 (ie, Figure 4 The larger the distance L shown, the greater the vibration amplitude of the vibration assembly 4, and the longer the duration of the vibration of the vibration assembly 4, under the same wind force. This also increases the benefit to power generation. It should be noted that while a larger distance L is more beneficial for power generation, in applications with strong winds, a larger distance L can cause greater damage to the overall structure of the anti-glare panel due to the vibrations generated by the vibration assembly 4, potentially reducing the panel's service life and hindering its long-term use.

[0045] In order to make the spacing (that is, the distance L) formed between the vibration component 4 and the bracket 1 adjustable, so that the anti-glare plate has a good service life in application scenarios with different wind strengths. In one embodiment of the present application, the substrate 2 is further provided with a slide bar assembly 6. Specifically, the slide bar assembly 6 forms a sliding connection with the substrate 2 along the first direction. The vibration component 4 corresponding to the substrate 2 is provided on the slide bar assembly 6. It is easy to understand that the spacing (that is, the distance L) formed between the vibration component 4 and the bracket 1 can be flexibly adjusted by the slide bar assembly 6. If the wind is strong, the distance L is shortened to protect the anti-glare plate; if the wind is weak, the distance L is increased to ensure the power generation efficiency. During use, the wind drives the vibration component 4 to vibrate, further the vibration component 4 drives the slide bar assembly 6 to vibrate, further the slide bar assembly 6 drives the substrate 2 to vibrate, further the substrate 2 drives the piezoelectric energy collection module 3 to vibrate; further the vibrating piezoelectric energy collection module 3 can generate electricity.

[0046] In the embodiment of the present application, the first direction can be any direction. For example, the first direction can be parallel to the horizontal plane, or in order to increase the contact area between the substrate 2 and the slide bar assembly 6, thereby improving the vibration transmission efficiency, in one embodiment of the present application, the first direction can be parallel to the width direction of the anti-glare plate (that is, the width direction of the substrate 2), such as Figure 4 As shown, the width of the anti-glare plate is distance B.

[0047] It should be noted that wind speeds generally vary from region to region, and from season to season within the same region. Therefore, in the embodiments of the present application, the distance L can be manually adjusted based on the region or season where the anti-glare panel is installed. For example, in regions or seasons with less wind, the distance L can be manually shortened; in regions or seasons with stronger wind, the distance L can be manually increased.

[0048] In order to automatically adjust the distance L and reduce manual labor or labor requirements, in one embodiment of the present application, the anti-glare plate may further include a driving device 5 disposed on the bracket 1, the driving device 5 being configured to drive the slide assembly 6 to reciprocate along the first direction. It should be understood that in this embodiment, the driving device 5 can automatically drive the slide assembly 6 to move along the first direction, thereby reducing the labor required to adjust the distance L.

[0049] In the embodiments of the present application, the drive device 5 can be any device capable of driving the slide bar assembly 6 to reciprocate in the first direction. In other words, the drive device 5 can be any device capable of linear reciprocating motion. For example, in the embodiments of the present application, the drive device 5 can include an electric push rod or a hydraulic push rod that corresponds one-to-one with the slide bar assembly 6. During use, the electric push rod or the hydraulic push rod drives the corresponding slide bar assembly 6 to perform linear reciprocating motion to adjust the distance L.

[0050] In order to reduce the number of electric push rods or hydraulic push rods used, in one embodiment of the present application, the drive device 5 may further include a first drive component 51 and a second drive component 52. The first drive component 51 is capable of reciprocating in the vertical direction; and if the first drive component 51 moves in the vertical direction, the first drive component 51 can drive the slide bar component 6 to move in the first direction. The second drive component 52 is used to drive the first drive component 51 to move in the vertical direction. It should be clear that since the first drive component 51 can drive each slide bar component 6 to move in the first direction when it moves in the vertical direction, it is only necessary to drive the first drive component 51 to move in the vertical direction through the second drive component 52. That is to say, in the embodiment of the present application, only the second drive component 52 is required to provide the driving force, which significantly reduces the number of electric push rods or hydraulic push rods (i.e., the driving force providing component) used.

[0051] In the embodiment of the present application, the first driving assembly 51 can be any assembly that can reciprocate in the vertical direction and drive each slide assembly 6 to move in the first direction. For example, in one embodiment of the present application, the first driving assembly 51 can include a first connecting rod 511 extending in the vertical direction and at least one second connecting rod 514 corresponding to each slide assembly 6. Specifically, Figure 8As shown, the first end of each second connecting rod 514 is hinged to the first connecting rod 511; the second end of each second connecting rod 514 is hinged to the slide assembly 6. When in use, if the first connecting rod 511 moves in the vertical direction, the second connecting rod 514 can drive the corresponding slide assembly 6 to move in the first direction. In another embodiment of the present application, the first driving assembly 51 includes a first connecting rod 511 extending in the vertical direction and at least one first elastic member 62. Specifically, as Figure 6 and Figure 7 As shown, the first connecting rod 511 is provided with at least one first inclined surface 513 corresponding to the slide bar assembly 6. Each first elastic member 62 stores a first elastic potential energy so as to make the slide bar assembly 6 collide with the corresponding first inclined surface 513. Figure 7 As shown, the slide bar assembly 6 always contacts the first inclined surface 513 under the elastic force of the first elastic member 62; therefore, if the first connecting rod 511 moves in the vertical direction, the slide bar assembly 6 can move in the first direction under the elastic force.

[0052] In the embodiment of the present application, in order to reduce the friction force formed between the slide bar assembly 6 and the first inclined surface 513, as shown in FIG. Figure 5 and Figure 7 As shown, a ball 63 can be provided on the slide bar assembly 6 at a position in contact with the first inclined surface 513. By providing the ball 63, the sliding friction between the slide bar assembly 6 and the first inclined surface 513 is converted into rolling friction, thereby reducing the friction between the slide bar assembly 6 and the first inclined surface 513.

[0053] It should be understood that in the embodiments of the present application, there is no limitation on the shape and structure of the first inclined surface 513. For example, the first inclined surface 513 may be a curved surface or a Figure 6 The same is true for the second inclined surface 520 described below, which will not be described in detail.

[0054] In the embodiment of the present application, the second drive assembly 52 can be any assembly that can drive the first drive assembly 51 (i.e., the first connecting rod 511 mentioned above) to reciprocate in the vertical direction. That is, in the embodiment of the present application, the second drive assembly 52 can be any assembly that can perform linear reciprocating motion. For example, the second drive assembly 52 includes an electric push rod or a hydraulic push rod. Alternatively, the second drive assembly 52 includes a threaded rod 522 and a motor 521. Figure 4 As shown, the threaded rod 522 is threadedly connected to the first connecting rod 511; the motor 521 is used to drive the threaded rod 522 to rotate forward or reverse. When in use, the motor 521 drives the threaded rod 522 to rotate forward or reverse, and the rotating threaded rod 522 can drive the first connecting rod 511 to reciprocate in the vertical direction.

[0055] It should be clear that in the embodiment of the present application, in order to be able to automatically adjust the distance L based on the real-time size of the wind speed (that is, to form an automatic control system), so that during long-term use, the damage to the anti-glare plate itself caused by the wind is minimized. In one embodiment of the present application, a wind sensor 7 can also be provided; the wind sensor 7 is used to measure the size of the wind speed. In this embodiment, based on the size of the wind speed, the distance L can be adjusted to a value corresponding to the wind speed with the help of the drive device 5, so that the damage to the anti-glare plate itself caused by the current wind speed is minimized. It should be clear that in the embodiment of the present application, the corresponding value between the wind speed and the distance L that can minimize the damage to the anti-glare plate itself can be an experimental value obtained by multiple physical tests, or a theoretical value obtained by simulation tests, or an empirical value.

[0056] In the automatic control system, with the increase of electronic devices (such as wind sensors 7, electric push rods, hydraulic push rods or motors 521), the structure and function of the automatic control system become more complex. This leads to an increase in the interactions and dependencies between the various parts of the automatic control system, making the operation and maintenance of the entire automatic control system more difficult. And each electronic device itself may have potential failure points. When the number of electronic devices in the automatic control system increases, the probability of failure will also increase accordingly. Moreover, the failure of one electronic device may affect the normal operation of other electronic devices, thereby affecting the stability of the entire automatic control system. In order to improve the stability of the automatic control system, in one embodiment of the present application, the second drive assembly 52 includes a sleeve 524, a third connecting rod 525, a fourth connecting rod 528, at least one second elastic member 512, and at least one third elastic member 526. As Figure 9 As shown, the sleeve 524 is mounted on the bracket 1. The third link 525 is slidably connected to the sleeve 524 in the second direction, and the third link 525 is provided with a second inclined surface 520. The first end of the fourth link 528 abuts the second inclined surface 520, and the second end of the fourth link 528 abuts the first link 511. A booster cover 529 is mounted on the first end of the third link 525 to increase the pressure exerted by wind on the third link 525. Each second elastic member 512 stores a second elastic potential energy, which tends to cause the first link 511 to move vertically upward. Each third elastic member 526 stores a third elastic potential energy, which tends to cause the third link 525 to move in the second direction, from the first end of the third link 525 to the second end. In this embodiment, the second direction can be any direction. For example, the second direction can be parallel to the horizontal plane, or perpendicular to the width of the anti-glare plate.

[0057] When in use, winds of different magnitudes will apply corresponding traction forces along the second direction to the third connecting rod 525 via the booster cover 529. It is easy to understand that the greater the wind speed, the greater the traction force on the third connecting rod 525; and the smaller the wind speed, the smaller the traction force on the third connecting rod 525. Specifically, Figure 9 and Figure 10 As shown, if the current wind speed increases, the traction force on the third link 525 increases, and under the action of the traction force, the third link 525 as a whole moves along the second direction from the second end of the third link 525 to the first end (hereinafter referred to as direction 1). Figure 10 As shown, if the third link 525 moves in direction one, then under the action of the second inclined surface 520, the fourth link 528 can move in the vertical downward direction; further, the fourth link 528 can push the first link 511 to move in the vertical downward direction. If the current wind speed decreases, the traction force on the third link 525 decreases, and under the action of the elastic force of the third elastic member 526, the third link 525 as a whole moves in the second direction from the first end of the third link 525 to the second end (hereinafter referred to as direction two). If the third link 525 moves in direction two, then Figures 6 to 8 As shown, under the elastic force of the second elastic member 512 , the first connecting rod 511 moves in a vertically upward direction.

[0058] It should be clear that in the embodiments of the present application, Figure 4 As shown, as the wind speed increases, the vertical distance first connecting rod 511 moves downward increases, and further, the distance L decreases. As the wind speed decreases, the vertical distance first connecting rod 511 moves downward decreases, and further, the distance L increases. In other words, this embodiment achieves automatic control of distance L based on wind speed without any electronic equipment. Compared to automatic control achieved with various electronic devices, the automatic control structure of this embodiment is not only less expensive but also more reliable and stable over long-term use.

[0059] In an embodiment of the present application, the sleeve 524 can be fixedly connected to the bracket 1. In order to make the second direction always parallel to the wind direction, in an embodiment of the present application, as shown in FIG. Figure 9 and Figure 10 As shown, the sleeve 524 can be rotatably connected to the bracket 1 through the bearing 523. During use, if the wind direction changes, the sleeve 524 can rotate under the action of the traction force until the second direction is parallel to the wind direction, that is, this embodiment can make the second direction always parallel to the wind direction.

[0060] In the embodiment of the present application, there is no limitation on the shape and structure of the first elastic member 62, the second elastic member 512, and the third elastic member 526. For example, the first elastic member 62, the second elastic member 512, and the third elastic member 526 can be elastic sheets or springs.

[0061] In a specific embodiment of the present application, Figure 9 and Figure 10 As shown, the third elastic member 526 can be a spring. In order to enable the third elastic member 526 to stably apply an elastic force parallel to the second direction to the third connecting rod 525, in this embodiment, the second drive assembly 52 further includes a guide rod 527 corresponding to each of the third elastic members 526. Each guide rod 527 is disposed on the third connecting rod 525, and the third elastic member 526 is movably sleeved on the exterior of the corresponding guide rod 527. Each guide rod 527 forms a sliding connection with the sleeve 524 along the second direction. When in use, the guide rod 527 can ensure that the elastic force generated by the third elastic member 526 is always parallel to the second direction.

[0062] It should be clear that in the embodiment of the present application, there is no limitation on the vibration component 4, which can be any component that can generate vibration against the wind. For example, in one embodiment of the present application, Figure 5 As shown, the vibration component 4 can be a cylindrical structure. The cylindrical structure of the vibration component 4 is not limited by the wind direction and can form vortex vibration with the wind in all directions. Or, as Figure 11 As shown, the slide bar assembly 6 includes a U-shaped slide bar 61, and the vibration assembly 4 is a solid cylindrical structure. Figure 12 As shown, the slide bar assembly 6 includes a first slide bar 611 and a second slide bar 612, and the vibration assembly 4 is a hollow tubular structure. The vibration assembly 4 is arranged on the first slide bar 611 or the second slide bar 612. The hollow tubular vibration assembly 4 is conducive to increasing the vibration amplitude of the vibration assembly 4. And the vibration assembly 4 is only connected to one of the first slide bar 611 or the second slide bar 612, so that the center of gravity of the vibration assembly 4 is unstable, which can further increase the vibration amplitude of the vibration assembly 4. Or, as Figure 13 As shown, the slide rod assembly 6 includes a first slide rod 611 and a second slide rod 612; the vibration assembly 4 includes a first circular tube 41 and a second circular tube 42 in the shape of a hollow tube; the axis lines of the first circular tube 41 and the second circular tube 42 coincide, and the first circular tube 41 is arranged on the first slide rod 611, and the second circular tube 42 is arranged on the second slide rod 612.

[0063] In the embodiment of the present application, there is no limitation on the piezoelectric energy harvesting module 3. That is, in the embodiment of the present application, the piezoelectric energy harvesting module 3 can be any module capable of generating electricity based on vibration. For example, Figure 2As shown, the piezoelectric energy collection module 3 may include a piezoelectric sheet 31 disposed on the substrate 2. Alternatively, in order to ensure that the piezoelectric sheet 31 is not corroded, as shown in FIG. Figure 2 As shown, a waterproof and anti-corrosion layer 32 is provided on the surface of the piezoelectric piece 31 .

[0064] It should be understood that the embodiment of the wind power generation device proposed in this application, based on the arrangement of the substrate, the piezoelectric energy collection module and the vibration component, can enable the anti-glare panel to generate electricity through the wind generated by the vehicle's movement or natural wind. During long-term use, the anti-glare panel will not experience a decrease in power generation efficiency due to excessive dust on the road, nor will it reflect light to affect the driver's vision. Compared to the production cost of photovoltaic panels, the production cost of piezoelectric energy collection modules is also relatively low, making it suitable for the application scenario of anti-glare panel power generation.

[0065] In an embodiment of the present application, the electric energy generated by the wind power generation device can be used to power various electrical equipment on the road (for example, street lights, traffic lights or surveillance cameras, etc.); of course, in order to increase the function of the anti-glare panel itself, warning signs or prompt signs that can emit light by electricity can also be set on the anti-glare panel, and these signs can be powered by the electric energy generated by the anti-glare panel to improve the safety of drivers driving at night.

[0066] It should be clear that in the embodiments of the present application, the piezoelectric energy collection module is combined with the anti-glare plate. This is a novel concept. It not only retains the traditional functions of the anti-glare plate, but also adds the ability to collect wind energy, which has not been adopted in existing anti-glare plate designs. The piezoelectric material generates electric charge through the vibration caused by the wind pressure on the anti-glare plate body. This process is generally regarded as converting useless wind energy (such as wind energy generated by vehicle movement) into useful electrical energy. This energy conversion and utilization method is innovative. With the help of the electricity generated by the anti-glare plate, roadside electronic equipment (such as street lights, surveillance cameras, etc.) can be powered, reducing the dependence of these electronic equipment on external power sources, which is significantly innovative in improving energy efficiency and sustainability. The design of the anti-glare plate takes into account the wind guide structure to ensure the effective transmission of wind energy. This design not only guarantees the main function of the anti-glare plate, but also optimizes the energy collection efficiency. The overall design of the anti-glare plate is simple, which is convenient for subsequent maintenance and upgrading. The anti-glare plate in the embodiment of the present application not only solves the glare problem, but also provides an additional energy supply for the road. This integrated design is innovative in improving the comprehensive performance of road facilities.

[0067] After introducing all the embodiments of the anti-glare plate proposed in this application, the following describes a control method for a wind power generation device proposed in this application. The control method is applied to a wind power generation device proposed in any of the above embodiments, such as Figure 14 As shown, the control method includes steps S100 to S300.

[0068] Step S100: Obtain the current wind speed.

[0069] It's important to note that higher wind speeds cause greater damage to the panels, so the distance L should be appropriately reduced to minimize damage. Lower wind speeds cause less vibration, so the distance L should be appropriately increased to improve power generation efficiency.

[0070] In the embodiment of the present application, there is no restriction on the method of obtaining the current wind speed. For example, the current wind speed can be obtained based on the wind sensor 7 described above, or based on the actual perception of the operator.

[0071] Step S200: Based on the current wind speed, the target position of the vibration component 4 is obtained.

[0072] It should be understood that, in order to balance wind damage to the anti-glare panel with power generation efficiency, there is a one-to-one correspondence between wind speed and distance L. That is, if the current wind speed can be determined, then distance L (i.e., the target position of the vibration assembly 4) can also be determined. As previously described, in the embodiments of the present application, the corresponding value between the current wind speed and distance L can be an experimental value obtained through multiple physical tests, a theoretical value obtained through simulation tests, or an empirical value.

[0073] Step S300: Adjust the vibration component 4 to a target position.

[0074] In the embodiment of the present application, there is no limitation on the method of adjusting the vibration component 4 to the target position. As described above, the vibration component 4 can be adjusted to the target position manually or automatically.

[0075] It should be clear that the control method embodiment of the wind power generation device proposed in the present application is based on the substrate, piezoelectric energy collection module and vibration component in the wind power generation device, and can enable the anti-glare panel to have the power generation function through the wind generated by the vehicle's movement or natural wind. During long-term use, the anti-glare panel will not suffer a decrease in power generation efficiency due to excessive dust on the road, nor will it reflect light to affect the driver's sight. Compared with the production cost of photovoltaic panels, the production cost of piezoelectric energy collection modules is also relatively low, which is suitable for the application scenario of anti-glare panel power generation. And through this control method, the position of the vibration component is adjusted based on the wind speed, and while ensuring the service life of the anti-glare panel, the power generation efficiency of the anti-glare panel can also be guaranteed to the greatest extent.

[0076] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
