Description

TECHNICAL FIELD

[0001] The application belongs to the field of photovoltaic panel protection devices, and particularly relates to a wind-resistant flow guide device for a photovoltaic panel. BACKGROUND

[0002] With the increasing global energy demand and the increasing environmental protection awareness, photovoltaic power generation, as a clean and renewable energy form, is increasingly widely concerned. In particular in China, the photovoltaic industry has developed rapidly, and photovoltaic power generation has become an important part of the new energy field. However, in the construction process of photovoltaic power stations, especially in special geographical environments such as deserts, photovoltaic power stations face many challenges, one of which is the wind resistance problem. In the desert area, the wind is strong, and the sand is frequent, which has a serious impact on the stable operation of the photovoltaic power station and the service life of the equipment, resulting in poor operation safety of the photovoltaic power station.

[0003] In order to obtain better light resources, photovoltaic supports are usually arranged to lift the photovoltaic cell panel to a position higher than the ground, and to tilt at a certain angle so that the photovoltaic cell panel can obtain a better light angle, which can easily improve the photoelectric conversion efficiency. In desert and other scenes, although the light resources are good, there are basically no shelters around, and the photovoltaic panel and its support directly withstand the invasion of strong wind. When the strong wind blows through the photovoltaic panel, the strength of the support and the stability of the connecting structure are tested, so it is necessary to set up a wind-resistant flow guide device that can protect the photovoltaic panel and its support.

[0004] A strong wind protection device for a photovoltaic power station disclosed in Patent No. CN219458950U includes a limiting clamping body, the limiting clamping body includes a clamping table plate and a clamping plate, the outer surface of the clamping plate movably has a wind guide mechanism, the top outer surface of the clamping table plate movably has a photovoltaic panel, the right outer surface of the photovoltaic panel is provided with a photovoltaic panel limiting clamping strip, and the right outer surface of the clamping table plate is fixedly connected with a supporting compression plate. Clamping plate one is clamped on the ground to reduce the gap between clamping plate one and the ground, so that the contact force between the wind source and the wind source is increased when the wind source flows, the arc-shaped flow guide chute on the top outer surface of clamping plate one is used to guide the flowing wind source, and the arc of the arc-shaped flow guide chute is used to guide the wind source upward, so as to reduce the contact force between the strong wind and the supporting frame.

[0005] However, the above-mentioned patent still has the following shortcomings:

[0006] 1. Since photovoltaic panels need to be installed in harsh environments for a long time, the wind-resistant and wind-guiding devices for photovoltaic panels should have a simple, stable structure and be less prone to failure. However, the structure of the above-mentioned patent is relatively complex, and the cost of installing such devices is high when a large number of photovoltaic panels are installed in photovoltaic power stations, which is not conducive to promotion and cost recovery.

[0007] 2. In order to increase power generation density, a large number of photovoltaic panels are set up side by side in photovoltaic power stations, relying on each other. Therefore, the wind-resistant and wind-guiding device should be able to be spliced ​​and combined to form a whole to effectively protect the side by side photovoltaic panels. At the same time, it is necessary to ensure that the wind-resistant and wind-guiding device can be modularly set up to adapt to different photovoltaic panel installation conditions and installation requirements. However, the above-mentioned device does not have these characteristics.

[0008] 3. Even if the above devices are arranged side by side and rely on each other, a narrow channel is formed between the bottom of the overlapping plate and the ground. If the wind comes from the side, the strong wind will easily stir up the sand and dust on the ground through the narrow channel, causing erosion and damage to the inside of the device. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by using a flexible wind-resistant hood. When strong winds blow towards the photovoltaic panels and their supports, the hood shields the supports from the airflow. Because the hood is flexible, it concaves under strong wind pressure, forming an arc surface. This guides the strong wind along the arc of the hood, preventing it from directly eroding the photovoltaic panels and supports. Furthermore, by incorporating exhaust vents, loops, and steel cables, when a side wind blows, the steel cable on the windward side is tightened, closing the exhaust vents and allowing the wind-resistant hood on the windward side to resist and guide the airflow. Conversely, the steel cable on the leeward side is loosened, causing the hood on the leeward side to bulge outward under wind pressure, expanding the exhaust vents and allowing the airflow entering the narrow channel to escape quickly, reducing the impact of airflow in the narrow passage. The flow speed and distance of the channel thus protect the support frame, the first connecting seat and other components. The wind-resistant guide hood connects the protective frame and the end of the base. The strength of the wind-resistant guide hood itself can be used to pull and fix the protective frame and photovoltaic panels, improving the stability of the photovoltaic panels and the support frame. This solution has a simple and stable structure, is not prone to failure, is suitable for long-term use in harsh environments, and is low in cost and easy to install, which is conducive to promotion, use and maintenance replacement. By setting zippers, the wind-resistant guide hoods on the photovoltaic panels that are set side by side and rely on each other in the photovoltaic power station can be spliced ​​together to form a whole, ensuring that the parallel photovoltaic panels are provided with complete and effective wind-resistant guidance. The connection method is simple and stable, low in cost, and can meet the modular setting requirements to adapt to different photovoltaic panel installation scenarios and conditions.

DETAILED DESCRIPTION

[0037] In order to make the personnel in the technical field better understand the application scheme, the technical solutions in the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application.

[0038] As shown in Figures 1-8 A wind-resistant fairing device of a photovoltaic panel, including a base 10, the center of the base 10 is fixedly connected with a support 11, the top of the support 11 is fixedly connected with a first connecting seat 12, the first connecting seat 12 is rotatably connected with a second connecting seat 13, the second connecting seat 13 and the first connecting seat 12 are locked by bolts, the top of the second connecting seat 13 is fixedly connected with a protective frame 14, and the protective frame 14 is fixedly connected with a photovoltaic panel 15.

[0039] By setting the support 11, the photovoltaic panel 15 is raised, so that the photovoltaic panel 15 obtains better light conditions, and at the same time, the photovoltaic panel 15 is isolated from the ground to avoid the influence of accumulated water on the ground on the photovoltaic panel 15 after rain, and at the same time, by setting the first connecting seat 12 and the second connecting seat 13, the inclination angle of the photovoltaic panel 15 is adjustable, so that the photovoltaic panel 15 can adjust the optimal light angle according to the actual environmental conditions, so as to ensure the optimal photoelectric conversion efficiency.

[0040] As shown in Figures 1-8As shown, the wind-resistant fairing 16 is arranged between the two ends of the protection frame 14 and the two ends of the base 10, and the two ends of the wind-resistant fairing 16 are fixedly connected with the base 10 and the protection frame 14 through the connecting buckles 17, respectively. The base 10 is provided with two groups of adjusting grooves 18 at the two ends, respectively, and the connecting buckles 17 below each wind-resistant fairing 16 are adjustably fixedly connected with the adjusting grooves 18. The wind-resistant fairing 16 is made of waterproof and air-tight flexible material, and the wind-resistant fairing 16 is kept inclined with the ground.

[0041] By arranging the flexible wind-resistant fairing 16, when the strong wind blows towards the photovoltaic panel 15 and the support 11, the support 11 is shielded by the wind-resistant fairing 16 to resist the airflow. Since the wind-resistant fairing 16 is flexible, the wind-resistant fairing 16 is concave to form a curved surface under the wind pressure of the strong wind, so that the strong wind is finally guided to change direction along the curved line direction of the wind-resistant fairing 16, thereby avoiding the direct erosion of the photovoltaic panel 15 and the support 11 by the strong wind.

[0042] In addition, the wind-resistant fairing 16 is connected to the end of the protection frame 14 and the base 10, and the strength of the wind-resistant fairing 16 can be used to pull and fix the protection frame 14 and the photovoltaic panel 15, thereby improving the stability of the photovoltaic panel 15 and the support 11. The structure of the scheme is simple and stable, and is not prone to failure. It is beneficial to long-term use in harsh environments, and has low cost, convenient installation, and is beneficial to popularization and use and maintenance and replacement.

[0043] As shown in Figures 1-8 Each wind-resistant fairing 16 is fixedly connected with a zipper 32 on both sides, and the adjacent zippers 32 can be engaged and fixed.

[0044] By arranging the zipper 32, the wind-resistant fairings 16 on each photovoltaic panel 15 arranged side by side and relying on each other in the photovoltaic power station are integrally spliced, so as to provide complete and effective wind-resistant and fairing effect for the photovoltaic panels arranged side by side. The connection mode is simple and stable, and the cost is low. At the same time, it can meet the modularization setting requirement to adapt to different photovoltaic panel installation scenes and conditions.

[0045] In addition, the zipper 32 is arranged at the edge of the flexible wind-resistant fairing 16, and the zipper 32 can enhance the strength of the edge of the wind-resistant fairing 16, so as to avoid damage such as breakage and tearing of the edge of the wind-resistant fairing 16 under the erosion of the strong wind for a long time, and improve the service life.

[0046] As shown in Figures 1-8As shown, two through air exhaust notches 19 are arranged on the surface of each wind-resistant fairing 16, a group of ring buckles 31 are arranged on the wind-resistant fairing 16 at both sides of each air exhaust notch 19, a steel wire rope 21 is arranged in each group of ring buckles 31, the top of each steel wire rope 21 is fixedly connected with the bottom side of the protection frame 14, a group of pulley seats 22 are fixedly connected with the bottom base 10 at the bottom end of each air exhaust notch 19, a pulley 23 is rotatably connected in each group of pulley seats 22, a bottom shell 24 and a top shell 25 are fixedly connected with the bottom base 10 at the corresponding position of each pulley 23, a winding disc 26 is rotatably connected in the bottom shell 24 and the top shell 25, the steel wire rope 21 is wound around the corresponding pulley 23 and passes through the bottom shell 24 and is finally fixedly connected with the outside of the corresponding winding disc 26, the winding disc 26 is fixedly connected with a worm gear 27, a worm 33 which is in meshing transmission connection with the worm gear 27 is rotatably connected between the two sides of the top shell 25, a stepping motor 28 is fixedly connected with the outside of the top shell 25, the power output end of each stepping motor 28 is in transmission connection with the corresponding worm 33, the top of the protection frame 14 is fixedly connected with a support plate 29, and the top of the support plate 29 is fixedly connected with a wind speed and direction instrument 30.

[0047] When the lateral wind comes, part of the airflow is resisted and guided by the wind-resistant fairing 16 on the windward side, and part of the airflow enters the gap formed below the photovoltaic panel 15 and the wind-resistant fairing 16. The side-by-side arrangement of the photovoltaic panel 15 and the wind-resistant fairing 16 forms a narrow channel. If the airflow cannot flow out after blowing into the narrow channel and the airflow speed increases, the ground dust is easily rolled up and the support 11, the first connecting seat 12 and the like are easily eroded and damaged.

[0048] By arranging the air exhaust notches 19, the ring buckles 31 and the steel wire ropes 21, when the lateral wind comes, the steel wire rope 21 on the windward side is tightened to close the air exhaust notches 19, so that the wind-resistant fairing 16 on the windward side resists and guides the airflow, and the steel wire rope 21 on the leeward side is loosened, so that the wind-resistant fairing 16 on the leeward side is convex under the wind pressure, so that the air exhaust notches 19 are enlarged, and then the airflow entering the narrow channel flows out quickly, the flow speed and flow distance of the airflow in the narrow channel are reduced, and the support 11, the first connecting seat 12 and the like are protected.

[0049] As shown, Figures 1-8 A group of flexible magnetic strips 20 which can be attracted to each other are fixedly connected at each air exhaust notch 19.

[0050] By arranging the flexible magnetic strips 20, the closing of the air exhaust notches 19 can be guided. When the steel wire rope 21 is tightened to close the air exhaust notches 19, the flexible magnetic strips 20 effectively avoid the problem of misalignment or loose closing of the air exhaust notches 19 when the steel wire rope 21 is tightened.

[0051] The support 11 is in a prismatic shape, and the surface of the support 11 is arranged at an angle of 45° with the front and side surfaces of the device. Through this arrangement, the support 11 can better resist lateral strong winds and the sand and dust rolled up by the winds, and the supporting strength and service life of the support 11 are improved.

[0052] In this embodiment, initially, the plurality of bases 10, supports 11, photovoltaic panels 15, and wind-resistant fairings 16 are arranged side by side and rely on each other. The inclination angle of the photovoltaic panel 15 can be adjusted by adjusting the first connecting seat 12 and the second connecting seat 13 to satisfy the optimal light angle. Then, the operator adjusts the connection position between the wind-resistant fairing 16 and the base 10 according to the angle of the photovoltaic panel 15 at this time, so that each wind-resistant fairing 16 is inclined to the ground and slightly straightened under stress, and the adjacent wind-resistant fairings 16 are connected and spliced into a complete whole through the zipper 32. The stepping motor 28 and the anemorumbus 30 are connected to the power supply and the control system, and then the installation work is completed.

[0053] When encountering a forward strong wind, the wind direction is detected by the anemorumbus 30 as a forward strong wind, and the anemorumbus 30 transmits the monitoring data to the control system. The control system controls the stepping motor 28 on the windward side to drive the winding disc 26 to rotate and tighten the steel wire rope 21 through the meshing transmission of the worm gear 27 and the worm 33. The flexible magnetic strip 20 is closed by magnetic force, and the steel wire rope 21 tightens the two sides of the exhaust slot 19 so that it cannot be opened.

[0054] The wind-resistant fairing 16 on the windward side is inwardly recessed by the strong wind, and the wind-resistant fairing 16 forms an arc surface to resist the strong wind and make the strong wind flow along the arc surface to change the airflow direction and avoid direct erosion of the photovoltaic panel 15. At the same time, the wind-resistant fairing 16 shields the support structure such as the support 11 and the first connecting seat 12, effectively avoiding the erosion of the support structure by the forward strong wind.

[0055] Since the wind-resistant fairing 16 is made of flexible material, the exhaust slot 19 is difficult to bend and recess although it is tightened by the steel wire rope 21, and the rest of the wind-resistant fairing 16 can still normally recess to form an arc surface to guide the airflow under wind pressure.

[0056] When encountering a lateral or composite direction strong wind, the wind direction is detected by the anemorumbus 30, and the anemorumbus 30 transmits the monitoring data to the control system. The control system controls the stepping motor 28 on the windward side to drive the winding disc 26 to rotate and tighten the steel wire rope 21 through the meshing transmission of the worm gear 27 and the worm 33, and controls the steel wire rope 21 on the leeward side to be loosened. The windward side of the wind-resistant fairing 16 will resist and guide part of the airflow.

[0057] The air flow entering the narrow passage under the photovoltaic panel 15 and the wind-resistant cowling 16 will blow the windward side of the wind-resistant cowling 16 outward to make it bulge, and the steel wire rope 21 on the leeward side no longer limits the exhaust slot 19, so the exhaust slot 19 on the bulging leeward side of the wind-resistant cowling 16 naturally opens, allowing the air flow entering the narrow passage to quickly flow out, reducing the flow speed and flow distance of the air flow in the narrow passage, and avoiding the air flow in a larger range to roll up dust to erode the support structure such as the support 11 and the first connecting seat 12.

[0058] The above-mentioned stepping motor 28, wind speed and direction instrument 30 and the like are mature prior art, and will not be described herein.

[0059] As some terms are used in the description and claims, those skilled in the art can understand that hardware manufacturers may use different names to refer to the same component. The description and claims of the present application do not distinguish components by name, but by the functional difference between components. As mentioned throughout the description and claims, "comprising" is an open term, which should be interpreted as "comprising but not limited to". "Substantially" means within an acceptable error range, and those skilled in the art can solve the technical problems within a certain error range and basically achieve the technical effects.
