Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an adjustable combined photovoltaic support based on photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, has been widely applied in ground-mounted power plants, rooftop distributed systems, and agricultural-solar hybrid systems. Adjustable modular photovoltaic (PV) systems, by adjusting the tilt angle of the photovoltaic panels, can improve power generation efficiency in different seasons and represent an important development direction for PV systems. However, PV systems are exposed to the outdoor environment for extended periods, and especially when facing severe weather such as strong winds and typhoons, wind loads pose a serious challenge to the safety of the system structure and the photovoltaic panels themselves.

[0003] An adjustable photovoltaic (PV) bracket is disclosed in patent application publication number 202511458404.X. Existing PV brackets have limited adjustment angles, which reduces the wind resistance of tilted PV panels during adjustment and lowers the safety factor in harsh, strong wind environments, making the PV panels prone to damage. An adjustable PV bracket includes a fixed base plate; a limiting ring is fixedly connected to the fixed base plate, and a turntable is rotatably connected to the limiting ring. The turntable is equipped with a support mechanism and a rotation mechanism. The support mechanism is used to place and install the PV panels, and the rotation mechanism is used to adjust the orientation angle of the PV panels. By rotating the shaft and the turntable, the azimuth and elevation angles of the PV panels are adjusted to ensure that the PV panels are always perpendicular to the sunlight, obtaining maximum light intensity and improving the power generation efficiency of the PV panels.

[0004] Existing photovoltaic (PV) support systems primarily employ the following wind-resistant measures: First, by increasing the strength of the support materials or adding passive reinforcement methods such as diagonal braces and ground anchors. However, these methods significantly increase cost and weight and cannot adaptively adjust according to wind speed. Second, by using an electric or hydraulically driven active tracking / wind-resistant system, which detects wind speed through sensors and drives a motor to change the angle of the PV panels. However, this system relies on power supply and control systems and is prone to problems such as sensor failure, motor overload, or response delay in severe weather. Furthermore, it is costly and not suitable for remote areas or large-scale power plants.

[0005] Regarding aerodynamic airflow guidance, some existing support structures have fixed deflectors or windbreaks installed at the edges of the photovoltaic panels. However, fixed deflectors will block sunlight for a long time, increase wind resistance throughout the year, and affect power generation efficiency; at the same time, they cannot respond in stages according to wind speed, causing unnecessary resistance in light winds and potentially being damaged due to insufficient strength in strong winds.

[0006] Therefore, it is necessary to provide an adjustable, modular photovoltaic support system based on photovoltaic power generation to solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide an adjustable combined photovoltaic support system based on photovoltaic power generation, so as to solve the problems of the prior art mentioned in the background.

[0008] Based on the above ideas, the present invention provides the following technical solution: an adjustable combined photovoltaic support structure based on photovoltaic power generation, comprising a mounting plate, with multiple photovoltaic panels laid on the top of the mounting plate, and further comprising: Two support frames are fixedly connected to the ground. Both support frames are hinged to the bottom of the mounting plate, and a connecting ring is fixedly connected to the bottom of the mounting plate. The connecting ring is detachably connected to the support frame by bolts. The airflow guiding mechanism includes airflow guiding components disposed on the upper and lower edges of the mounting plate and airflow breaking components disposed on the left and right edges of the mounting plate; The air guide assembly includes multiple fixed rods, each with a connecting plate fixedly connected to both ends. The connecting plates are fixedly connected to the mounting plate. A rotating cylinder is rotatably connected to the outside of the fixed rods. A primary air guide plate is fixedly connected to the outside of the rotating cylinder. The primary air guide plate is kept horizontal with the photovoltaic panel. Under wind power, the rotating cylinder drives the primary air guide plate to deflect toward the photovoltaic panel. A damping element is provided between the rotating cylinder and the connecting plate. The wind-breaking component includes a storage frame with a pop-out slot on one side. The storage frame contains a wind-breaking plate. The storage frame also contains a passive triggering component and a locking component. When the wind speed exceeds a preset threshold, the passive triggering component unlocks the locking component, causing the wind-breaking plate to automatically pop out to the pop-out position and lock after rapid movement. It automatically resets when the wind speed decreases.

[0009] As a further aspect of the present invention: the damping component includes a fixed frame, which is sleeved on the outside of the rotating cylinder and fixedly connected to one side of the connecting plate. A rotating ring is rotatably connected to one side of the fixed frame, and the rotating ring and the fixed frame form an annular space. The rotating ring is fixedly connected to the rotating cylinder through a support plate.

[0010] As a further aspect of the present invention: the damping component further includes two fixed plates, which are fixedly connected inside the fixed frame, and a squeezing plate is provided between the two fixed plates. The squeezing plate is fixedly connected to the rotating ring, and an elastic element is fixedly connected between the squeezing plate and one of the fixed plates.

[0011] As a further aspect of the present invention: a secondary air guide plate is slidably connected inside the primary air guide plate, and pull plates are fixedly connected to both sides of the secondary air guide plate. A first spring is fixedly connected between the pull plates and the primary air guide plate. A magnetic arc plate is fixedly connected to the outside of the fixed rod. A magnetic plate is fixedly connected to one end of the secondary air guide plate near the fixed rod. The magnetic plate passes through the magnetic arc plate and contacts the magnetic arc plate. The magnetic plate and the magnetic arc plate are magnetically attracted to each other.

[0012] As a further aspect of the present invention: a first gear is fixedly connected to the outer side of the rotating ring, a second gear is meshed with the outer side of the first gear, a take-up reel is fixedly connected to the outer side of the second gear, a take-up rope is wound around the outer side of the take-up reel, the take-up rope passes through the rotating cylinder and is fixedly connected to the pull plate, when the first gear drives the second gear to rotate, the take-up reel unwinds the take-up rope for the secondary air guide plate to slide out.

[0013] As a further embodiment of the present invention: a first fixing rod is fixedly connected inside the storage frame, a sliding plate is fixedly connected outside the windbreak plate, the first fixing rod passes through the sliding plate and is slidably connected to the sliding plate, a storage spring is fixedly connected to one side of the storage frame inside the sliding plate, and a return spring is fixedly connected to the other side of the storage frame inside the sliding plate.

[0014] As a further embodiment of the present invention: the locking component includes a first magnet, which is disposed on one side inside the storage frame, and a second magnet is fixedly connected to one side of the air-breaking plate. The first magnet and the second magnet are magnetically attracted to each other, and an elastic hook is fixedly connected to the side of the air-breaking plate near the first magnet. A limit plate is provided inside the storage frame, and the elastic hook is hooked into the inside of the limit plate.

[0015] As a further embodiment of the present invention: the passive triggering component includes a second fixed rod, which is fixedly connected inside the storage frame. A movable plate is provided inside the storage frame. The second fixed rod passes through the movable plate and is slidably connected to it. A first pull plate is fixedly connected to the outside of the movable plate. A third telescopic rod is fixedly connected to the top of the first pull plate. The third telescopic rod is fixedly connected to a limiting plate. A fixed side plate is fixedly connected inside the storage frame. A groove is provided on the outside of the fixed side plate. A horizontal shaft is fixedly connected to the outside of the limiting plate and is located inside the groove. When the third telescopic rod pulls the limiting plate to move laterally, the limiting plate moves diagonally downward and separates from the elastic hook. A second pull plate is fixedly connected to the outside of the movable plate and is fixedly connected to a first magnet.

[0016] As a further embodiment of the present invention: the passive triggering component further includes a horizontal plate, which is fixedly connected to the outside of the movable plate, and an extrusion groove is opened on the outside of the horizontal plate. A windproof frame is provided on the top of the storage frame, and an extrusion frame is fixedly connected to the bottom of the windproof frame. The extrusion frame extends into the extrusion groove opened in the horizontal plate, and a second telescopic rod and a third spring are fixedly connected between the extrusion frame and the storage frame.

[0017] As a further embodiment of the present invention: a limiting plate is fixedly connected inside the storage frame, and multiple positioning grooves are opened on the outer side of the limiting plate. The limiting plate is set on one side of the moving plate, and a protrusion corresponding to the multiple positioning grooves is set on the side of the moving plate near the limiting plate. A locking block is set on the outer side of the air-breaking plate, and a vertical plate is fixedly connected to the outer side of the air-breaking plate. A first telescopic rod and a second spring are fixedly connected between the vertical plate and the locking block.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. At the same time, the rotating cylinder drives the primary air guide plate to deflect, so that it forms an inclined angle with the surface of the photovoltaic panel, which greatly reduces the wind load and disrupts the formation of lift. The primary air guide plate located at the lower edge rotates upward to prevent strong winds from penetrating the bottom of the photovoltaic panel and avoids the photovoltaic panel being overturned; the primary air guide plate located at the upper edge rotates downward to guide the airflow upward to bypass the module and reduce the front pressure.

[0019] 2. When the wind speed decreases and reset is required, the first gear rotates in the opposite direction, which drives the second gear to rotate in the opposite direction. This causes the winding reel to pull the secondary air guide plate through the winding rope, overcoming the force of the first spring and retracting to reset. The reel then completely retracts into the primary air guide plate, forming a stepped surface between the primary and secondary air guide plates. This surface can suppress airflow separation, reduce eddy current losses, and has a higher lift-to-drag ratio than a single long blade, resulting in smoother airflow.

[0020] 3. The ejected windbreak acts like a baffle perpendicular to the side frame, guiding the lateral airflow away and reducing the wind pressure area acting on the side of the photovoltaic panel. In addition, strong crosswinds passing over the edge of the flat panel generate alternating Karman vortex streets, causing the photovoltaic panel to sway from side to side; the ejected windbreak changes the geometry of the side edge, disrupting the vortex shedding frequency, thereby fundamentally suppressing flutter.

[0021] 4. When the air-breaking plate moves to near its fully retracted position, the first and second magnets are aligned again, and the magnetic attraction begins to work, assisting in pulling the air-breaking plate further into place. At the same time, the elastic hook re-engages with the limiting plate, completing the re-locking of the air-breaking plate and preparing for the next lateral airflow. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0027] like Figures 1 to 10 As shown, an adjustable combined photovoltaic support system based on photovoltaic power generation includes the following embodiments: Example 1: Includes a mounting plate 1, with multiple photovoltaic panels 103 laid on the top of the mounting plate 1, and also includes: Two support frames 101 are fixedly connected to the ground. Both support frames 101 are hinged to the bottom of the mounting plate 1. A connecting ring 102 is fixedly connected to the bottom of the mounting plate 1. The connecting ring 102 is detachably connected to the support frame 101 by bolts. The airflow guiding mechanism includes airflow guiding components disposed on the upper and lower edges of the mounting plate 1 and airflow breaking components disposed on the left and right edges of the mounting plate 1. The air guiding assembly includes multiple fixed rods 201, with connecting plates 2 fixedly connected to both ends of the multiple fixed rods 201. The connecting plates 2 are fixedly connected to the mounting plate 1. A rotating cylinder 202 is rotatably connected to the outside of the fixed rods 201. A primary air guiding plate 203 is fixedly connected to the outside of the rotating cylinder 202. The primary air guiding plate 203 is kept horizontal with the photovoltaic panel 103. Under the drive of wind, the rotating cylinder 202 drives the primary air guiding plate 203 to deflect toward the photovoltaic panel 103. A damping element is provided between the rotating cylinder 202 and the connecting plate 2. The wind-breaking component includes a storage frame 3, with a pop-out slot 301 on one side of the storage frame 3. The storage frame 3 is equipped with a wind-breaking plate 6. The storage frame 3 is also equipped with a passive triggering component and a locking component. When the wind speed exceeds a preset threshold, the passive triggering unlocking and locking components are activated, causing the wind-breaking plate 6 to automatically pop out to the pop-out position and lock after rapid movement. It automatically resets when the wind speed decreases.

[0028] In practice, the photovoltaic panel 103 is installed on the top of the mounting plate 1 using bolts and other fasteners. When the angle needs to be adjusted, the mounting plate 1 rotates around its hinge with the support frame 101; after the angle is adjusted to the correct position, it is fixed by bolts inserted between the connecting ring 102 and the support frame 101, thereby achieving the positioning and locking of the angle of the mounting plate 1. This solution has a flow guiding mechanism around the mounting plate 1, with air guiding components at the upper and lower edges of the mounting plate 1. In the initial state, the primary air guiding plate 203 remains horizontal with the photovoltaic panel 103, without causing obstruction. When a strong wind blows towards the photovoltaic panel 103, the wind force drives the rotating cylinder 202 to rotate around the fixed rod 201. At the same time, the rotating cylinder 202 drives the primary wind guide plate 203 to deflect, so that it forms an inclined angle with the surface of the photovoltaic panel 103, preferably 30°~45°, which greatly reduces the wind load and disrupts the formation of lift. The primary wind guide plate 203 located at the lower edge rotates upward to prevent strong wind from penetrating the bottom of the photovoltaic panel and avoids the photovoltaic panel being overturned; the primary wind guide plate 203 located at the upper edge rotates downward to guide the airflow upward to bypass the module and reduce the front pressure.

[0029] When crosswinds parallel to the long side of the photovoltaic panel directly impact the side frame, they generate lateral thrust and torsional moment, which can easily lead to twisting of the support frame 101, hinge fatigue, or even overall overturning. To address this issue, this solution incorporates wind-breaking components on the left and right edges. When the wind speed exceeds a preset threshold, the passive triggering component automatically activates, unlocking the locking component and causing the wind-breaking plate 6 to pop out. Once deployed, the wind-breaking plate 6 acts like a baffle perpendicular to the side frame, guiding the lateral airflow away from its path, thereby effectively reducing the wind pressure area acting on the side of the photovoltaic panel 103 and lowering the lateral force and torsional moment.

[0030] In this embodiment, the damping component includes a fixed frame 4, which is sleeved on the outside of the rotating cylinder 202 and fixedly connected to one side of the connecting plate 2. A rotating ring 405 is rotatably connected to one side of the fixed frame 4. The rotating ring 405 and the fixed frame 4 form an annular space. The rotating ring 405 is fixedly connected to the rotating cylinder 202 through a support plate.

[0031] The damping component also includes two fixed plates 402, which are fixedly connected inside the fixed frame 4. A squeezing plate 401 is provided between the two fixed plates 402. The squeezing plate 401 is fixedly connected to the rotating ring 405. An elastic element 403 is fixedly connected between the squeezing plate 401 and one of the fixed plates 402. The space between the squeezing plate 401 and the fixed plate 402 is filled with a shear-thickening fluid. A flow groove is provided on the outer side of the squeezing plate 401 for the shear-thickening fluid to pass through.

[0032] In practice, when the wind force blowing towards the front of the photovoltaic panel 103 increases, the wind force drives the rotating cylinder 202 to rotate. The rotating cylinder 202 drives the extrusion plate 401 to slide between the two fixed plates 402 inside the fixed frame 4 via the rotating ring 405. During the sliding process, the extrusion plate 401 extrudes the shear-thickening fluid on one side, forcing the fluid to flow into the other side through the flow groove opened on the extrusion plate 401; at the same time, the extrusion plate 401 compresses the elastic element 403. Since the viscosity of the shear-thickening fluid increases sharply when subjected to rapid extrusion, it hardens, generating strong resistance to the flow of the fluid, thereby damping the sliding of the extrusion plate 401, and thus hindering the continued rotation of the rotating cylinder 202 and the first-stage air guide plate 203. When the wind speed drops suddenly, the shear-thickened fluid remains in a high-viscosity state, allowing the rotating cylinder 202 and the first-stage guide vane 203 to maintain their existing deflection angles. This prevents the first-stage guide vane 203 from swinging back and forth or failing to form an effective guiding angle in time due to rapid changes in wind speed. When the wind speed suddenly drops, the fluid remains in a high-viscosity state, providing sufficient damping force to keep the first-stage guide vane 203 at its original deflection angle. This prevents the guide vane from frequently returning to its original position or becoming displaced due to wind pressure fluctuations, ensuring continuous protection during intermittent strong winds.

[0033] In this embodiment, a secondary air guide plate 5 is slidably connected inside the primary air guide plate 203, and pull plates 508 are fixedly connected to both sides of the secondary air guide plate 5. A first spring 507 is fixedly connected between the pull plates 508 and the primary air guide plate 203. A magnetic arc plate 502 is fixedly connected to the outside of the fixing rod 201. A magnetic plate 501 is fixedly connected to one end of the secondary air guide plate 5 near the fixing rod 201. The magnetic plate 501 passes through the magnetic arc plate 502 and contacts the magnetic arc plate 502. The magnetic plate 501 and the magnetic arc plate 502 are magnetically attracted to each other.

[0034] A first gear 503 is fixedly connected to the outside of the rotating ring 405. A second gear 504 is meshed with the outside of the first gear 503. A take-up reel 505 is fixedly connected to the outside of the second gear 504. A take-up rope 506 is wound around the outside of the take-up reel 505. The take-up rope 506 passes through the rotating cylinder 202 and is fixedly connected to the pull plate 508. When the first gear 503 drives the second gear 504 to rotate, the take-up reel 505 unwinds the take-up rope 506 for the secondary air guide plate 5 to slide out.

[0035] In practice, as the frontal wind force increases, the rotation amplitude of the primary air guide plate 203 around the fixed rod 201 also increases; the higher the wind speed, the larger the rotation angle. As the primary air guide plate 203 rotates with the rotating cylinder 202, the secondary air guide plate 5 inside it also rotates synchronously around the fixed rod 201. A magnetic plate 501 is fixedly connected to one end of the secondary air guide plate 5 near the fixed rod 201. When the primary air guide plate 203 rotates to a preset angle, such as 30°~45°, the magnetic plate 501 disengages from the magnetic arc plate 502 fixedly mounted on the fixed rod 201. Simultaneously, the first gear 503 fixedly connected to the outside of the rotating ring 405 drives the meshing second gear 504 to rotate. The second gear 504 drives the winding reel 505 to rotate, causing the winding rope 506 wound around the outside of the winding reel 505 to unwind. At this point, the secondary guide vane 5 slides outward along the internal groove of the primary guide vane 203 under the elastic force of the first spring 507, so that the primary guide vane 203 and the secondary guide vane 5 together form a longer stepped airflow guiding structure, thereby extending the airflow guiding length. The essence of the airflow guide vane is to change the airflow direction, and the airflow deflection efficiency is directly proportional to the chord length of the vane, i.e., the airflow guiding length: the longer the length, the more fully the airflow is guided, and the more significant the wind pressure reduction effect. When the wind speed decreases later and needs to be reset, the first gear 503 rotates in the opposite direction, driving the second gear 504 to rotate in the opposite direction, so that the winding reel 505 pulls the secondary guide vane 5 through the winding rope 506 to overcome the force of the first spring 507 and retract and reset, completely retracting into the interior of the primary guide vane 203. The primary and secondary guide vanes form a stepped surface, which can suppress airflow separation, reduce vortex losses, and has a higher lift-to-drag ratio than a single long vane, resulting in smoother airflow.

[0036] Example 3: A first fixing rod 602 is fixedly connected inside the storage frame 3, and a sliding plate 601 is fixedly connected to the outside of the windbreak plate 6. The first fixing rod 602 passes through the sliding plate 601 and is slidably connected to the sliding plate 601. A storage spring 603 is fixedly connected to one side of the inside of the storage frame 3, and a return spring 604 is fixedly connected to the other side of the inside of the storage frame 3.

[0037] The locking component includes a first magnet 701, which is disposed on one side inside the storage frame 3, and a second magnet 702 is fixedly connected to one side of the air-breaking plate 6. The first magnet 701 and the second magnet 702 are magnetically attracted to each other, and an elastic hook 703 is fixedly connected to the side of the air-breaking plate 6 near the first magnet 701. A limit plate 708 is provided inside the storage frame 3, and the elastic hook 703 is hooked into the limit plate 708.

[0038] In practice, under normal windless conditions, the windbreak panel 6 retracts into the storage frame 3. At this time, the windbreak panel 6, through the magnetic attraction between the second magnet 702 and the first magnet 701, and the tension of the return spring 604, compresses the energy storage spring 603; simultaneously, the elastic hook 703 hooks into the limiting plate 708, keeping the windbreak panel 6 in a compressed and locked state. When the wind speed exceeds a preset threshold, the passive component action is triggered and the limiting plate 708 is unlocked. The elastic hook 703 disengages, and the energy storage spring 603 quickly pushes the sliding plate 601 to move, causing the windbreak panel 6 to slide out of the storage frame 3. After popping out, the windbreak panel 6 acts like a baffle perpendicular to the side frame, guiding the lateral airflow away and reducing the wind pressure area acting on the side of the photovoltaic panel 103. In addition, strong crosswinds passing over the edge of the flat panel generate alternating Karman vortex streets, causing the photovoltaic panel 103 to sway and flutter from side to side; the popped-out windbreak 6 changes the geometry of the side edge, disrupts the vortex shedding frequency, and thus fundamentally suppresses flutter.

[0039] In this embodiment, the passive triggering component includes a second fixed rod 802. The second fixed rod 802 is fixedly connected inside the storage frame 3. A movable plate 801 is provided inside the storage frame 3. The second fixed rod 802 passes through the movable plate 801 and is slidably connected to the movable plate 801. A first pull plate 808 is fixedly connected to the outside of the movable plate 801. A third telescopic rod 809 is fixedly connected to the top of the first pull plate 808. The third telescopic rod 809 is fixedly connected to the limiting plate 708. A fixed side plate 810 is fixedly connected inside the storage frame 3. A sliding groove is provided on the outside of the fixed side plate 810. A horizontal shaft is fixedly connected to the outside of the limiting plate 708. The horizontal shaft is located inside the sliding groove. When the third telescopic rod 809 pulls the limiting plate 708 to move laterally, the limiting plate 708 moves diagonally downward and separates from the elastic hook 703. A second pull plate 811 is fixedly connected to the outside of the movable plate 801. The second pull plate 811 is fixedly connected to the first magnet 701.

[0040] The passive triggering component also includes a horizontal plate 805, which is fixedly connected to the outside of the movable plate 801. A squeezing groove is opened on the outside of the horizontal plate 805. A windproof frame 803 is provided on the top of the storage frame 3. A squeezing frame 804 is fixedly connected to the bottom of the windproof frame 803. The squeezing frame 804 extends into the squeezing groove opened in the horizontal plate 805. A second telescopic rod 806 and a third spring 807 are fixedly connected between the squeezing frame 804 and the storage frame 3.

[0041] In practice, when strong lateral winds act on the windbreak frame 803, the windproof cloth on the windbreak frame 803 is driven by wind pressure, causing the windbreak frame 803 and its fixedly connected extrusion frame 804 to slide together. The extrusion frame 804 extends into the extrusion groove on the horizontal plate 805 and slides in the groove, pushing the horizontal plate 805 to move the moving plate 801 away from the windbreak plate 6. The moving plate 801 drives the first pull plate 808 fixedly connected to it to move synchronously. The first pull plate 808 pulls the limiting plate 708 to move through the third telescopic rod 809. The horizontal axis on the limiting plate 708 slides along the sliding groove opened on the fixed side plate 810, causing the limiting plate 708 to move obliquely downward, thereby separating the limiting plate 708 from the elastic hook 703 and releasing the mechanical lock on the windbreak plate 6. At the same time, the moving plate 801 drives the first magnet 701 to move away from the second magnet 702 through the second pull plate 811, weakening or eliminating the magnetic adsorption and further reducing the traction force on the sliding plate 601. Thus, the windbreak 6 slides out of the storage box 3 quickly under the push of the energy storage spring 603, and unlocks and pops out by using the wind itself, achieving the effect of automatic airflow guidance.

[0042] In this embodiment, a limiting plate 708 is fixedly connected inside the storage frame 3. Multiple positioning grooves are provided on the outer side of the limiting plate 708. The limiting plate 708 is located on one side of the moving plate 801. The moving plate 801 is provided with protrusions corresponding to the multiple positioning grooves on the side near the limiting plate 708. A locking block 705 is provided on the outer side of the air-breaking plate 6. A vertical plate 704 is fixedly connected to the outer side of the air-breaking plate 6. A first telescopic rod 706 and a second spring 707 are fixedly connected between the vertical plate 704 and the locking block 705.

[0043] In practice, when the windbreak plate 6 slides outward under the push of the storage spring 603, the locking block 705 on the outer side of the windbreak plate 6 continuously contacts and slides through multiple positioning slots on the limiting plate 708 under the action of the second spring 707, forming a unidirectional movement similar to ratchet. When the windbreak plate 6 stops sliding to its limit position, the locking block 705 inserts into the corresponding positioning slot under the elastic force of the second spring 707, thereby locking the pop-out position of the windbreak plate 6 and preventing it from rebounding due to wind fluctuations or aerodynamic reaction forces, ensuring that the airflow guiding effect remains effective.

[0044] When the wind speed drops below the threshold and the wind pressure on the windbreak frame 803 disappears, the windbreak frame 803 resets under the action of the third spring 807, driving the transmission mechanism's compression frame 804, horizontal plate 805, and moving plate 801 to move in the opposite direction. When the moving plate 801 resets, the protrusion on one side inserts into the positioning groove on the limiting plate 708, pushing the locking block 705, which was originally stuck in the groove, outward and releasing the lock on the windbreak plate 6. Subsequently, the reset spring 604 slowly pushes the sliding plate 601 and the windbreak plate 6 back into the storage frame 3. When the windbreak plate 6 moves to a position close to the fully retracted position, the first magnet 701 and the second magnet 702 are aligned again at the same center, and the magnetic attraction force begins to work, assisting in pulling the windbreak plate 6 to retract further into place. At the same time, the elastic hook 703 re-engages with the limiting plate 708, completing the re-locking of the windbreak plate 6 and preparing for the next lateral airflow.
