Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic technology, and in particular to a wind-resistant structure and a marine photovoltaic system. Background Technology

[0002] Photovoltaic panels are the core component of a photovoltaic power generation system. They absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Compared with land, the vast sea surface provides an excellent site for building photovoltaic power plants, effectively alleviating the site limitations of laying solar panels on land and bringing a continuous source of offshore power to coastal areas and even inland areas.

[0003] Existing offshore photovoltaic (PV) systems typically employ either fixed or floating support systems. Fixed PV structures are more difficult and costly to construct, but are suitable for rough seas. However, fixed offshore PV systems still need to withstand harsh sea conditions and require high wind resistance; otherwise, they may capsize.

[0004] Therefore, it is necessary to develop a wind-resistant structure and a marine photovoltaic system to enable the marine photovoltaic system to have better wind resistance. Utility Model Content

[0005] The purpose of this invention is to provide a wind-resistant structure and a marine photovoltaic system to solve the problem of poor wind resistance performance of existing marine photovoltaic systems.

[0006] To solve the above-mentioned technical problems, this utility model provides a wind-resistant structure for offshore photovoltaic systems. The wind-resistant structure is installed along the lower edge of the steel truss of the offshore photovoltaic system. The wind-resistant structure includes a rotating shaft, a guide plate, a wind-receiving plate, a cable, and a weight. The axial direction of the rotating shaft is arranged along the lower edge of the steel truss and is rotatably connected to the steel truss. The guide plate is fixedly connected to the rotating shaft. The wind-receiving plate is located at both ends of the guide plate and is fixedly connected to the rotating shaft. The wind-receiving plate and the guide plate have a predetermined included angle. The cable is connected to the wind-receiving plate. The weight is connected to the cable.

[0007] Optionally, the predetermined included angle is 90°.

[0008] Optionally, the wind-resistant structure includes two fixed sleeves, which are fixedly installed on the steel truss, and the rotating shaft is rotatably connected to the fixed sleeves.

[0009] Optionally, the wind-resistant structure further includes one or more elastic sleeves, which are arranged on the steel truss and located between the two fixed sleeves, and the elastic sleeves are rotatably connected to the rotating shaft.

[0010] Optionally, the elastic sleeve includes a truss connecting block, an elastic element, and a pivot support block. The truss connecting block is fixedly connected to the steel truss. The pivot support block is connected to the truss connecting block through the elastic element to form a pivot channel. The pivot is installed in the pivot channel and can rotate within the pivot channel. The pivot support block is used to support the pivot.

[0011] Optionally, a limiting block is also included, which is installed on the steel truss to restrict the overturning of the guide plate.

[0012] Optionally, it also includes a guide vane connecting block, which is fixedly connected to the guide vane and rotatably connected to the rotating shaft.

[0013] Optionally, the guide plate has at least one grille hole, which is located at the lower part of the guide plate.

[0014] Optionally, the grille opening is located below the rotating shaft.

[0015] This utility model also provides a marine photovoltaic system, comprising: a plurality of vertically arranged pillars, a steel truss arranged above the pillars, purlins arranged on the steel truss, photovoltaic panels laid on the purlins, and the aforementioned wind-resistant structure arranged at the lower end of the steel truss, wherein the pillars are arranged from high to low, and the upper and lower layers of the steel truss are arranged in parallel.

[0016] The wind-resistant structure and marine photovoltaic system provided by this utility model have the following beneficial effects: By using a heavy object to pull the wind-receiving plate, the wind-receiving plate is rotated, which in turn makes the guide plate tend to be horizontal. This allows the wind-receiving plate to rotate when the wind load on the wind-receiving plate is small or there is no wind, so the heavy object drives the cable to rotate the wind-receiving plate, thereby restoring the guide plate system to a horizontal position and putting it into a non-operating state. In windy weather, the wind-receiving plate rotates under the action of wind force, thereby driving the guide plate to rotate and making the guide plate form an angle with the horizontal direction. This serves to block the wind for the photovoltaic panel, change the wind field characteristics, reduce the wind load, and improve the wind resistance performance of the offshore photovoltaic system. In this way, the position of the guide plate can be automatically adjusted according to the magnitude of the wind load, so as to adjust the wind resistance status of the offshore photovoltaic system in real time.

Detailed Implementation

[0019] refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an existing offshore photovoltaic system from one perspective. Figure 2 This is a structural schematic diagram of an existing offshore photovoltaic (PV) system from another perspective. In existing technologies, offshore PV systems typically include multiple vertically arranged support columns 100, a steel truss 200 positioned above the support columns 100, purlins mounted on the steel truss 200, and photovoltaic panels 400 laid on the purlins. The support columns 100 are arranged from high to low, and the upper and lower layers of the steel truss 200 are arranged parallel to each other, allowing the photovoltaic panels 400 to be inclined. Specifically, the steel truss 200 and photovoltaic panels 400 of the offshore PV system have a high end and a low end. Relative to the vertical direction, the high end is located at the upper part of the vertical direction, and the low end is located at the lower part of the vertical direction.

[0020] Offshore photovoltaic systems are suitable for offshore areas with large winds and waves. The wind resistance performance of the structure is closely related to the structure's shape and form. When facing large wind loads, wind resistance performance can often be improved by thickening or adding structural components, but this comes at the cost of a significant increase in structural costs.

[0021] Therefore, after research, the applicant found that, for offshore rigid photovoltaic structures, the characteristics of the structure's support structure can be utilized to add a wind deflector 520 at the windward position to reduce wind load by blocking the wind flow and changing the wind field characteristics, thereby improving the wind resistance performance of the photovoltaic structure.

[0022] The applicant further discovered that the photovoltaic panels 400 of the offshore photovoltaic system are laid on the steel truss 200 via purlins, and the photovoltaic panels 400 have a portion that cantilevered outward relative to the steel truss 200 itself. This factor needs to be considered when installing the guide plate 520. At the same time, since the guide plate 520 may block some sunlight in the morning sun, affecting the power generation efficiency of the photovoltaic panels 400, it is necessary to consider the adaptability of the guide plate 520 under different wind intensities. That is, through structural measures, the guide plate 520 should be able to stand upright under strong wind conditions, and remain flat under weak wind or no wind conditions to ensure that the photovoltaic panels 400 receive sufficient sunlight.

[0023] Based on this, the applicant proposes a wind-resistant structure 500 and a marine photovoltaic system. The wind-resistant structure 500 and the marine photovoltaic system of this application will be described below with reference to specific embodiments.

Figure 11This is a partial structural diagram of the wind-resistant joint of the marine photovoltaic system in a non-operating state according to another embodiment of the present invention. This embodiment provides a wind-resistant structure 500 for a marine photovoltaic system, installed along the lower edge of the steel truss 200 of the marine photovoltaic system. It includes a rotating shaft 510, a guide plate 520, a wind-receiving plate 530, a cable 540, and a weight. The axial direction of the rotating shaft 510 is arranged along the lower edge of the steel truss 200 and is rotatably connected to the steel truss 200. The guide plate 520 is fixedly connected to the rotating shaft 510. The wind-receiving plate 530 is located at both ends of the guide plate 520 and is fixedly connected to the rotating shaft 510. The wind-receiving plate 530 and the guide plate 520 have a predetermined included angle. The cable 540 is connected to the wind-receiving plate 530. The weight is connected to the cable 540.

[0031] By pulling the wind-receiving plate 530 with a heavy object, the wind-receiving plate 530 is rotated, which in turn makes the guide plate 520 tend to be horizontal. In this way, when the wind load on the wind-receiving plate 530 is small or there is no wind, the heavy object drives the cable 540 to rotate the wind-receiving plate 530, thereby restoring the guide plate 520 system to a horizontal position and putting it into a non-operating state. In windy weather, the wind-receiving plate 530 rotates under the action of wind force, thereby driving the guide plate 520 to rotate, so that the guide plate 520 has an angle with the horizontal direction. This serves to block the wind for the photovoltaic panel 400, change the wind field characteristics, reduce the wind load, and improve the wind resistance performance of the offshore photovoltaic system. Thus, the position of the guide plate 520 is automatically adjusted according to the magnitude of the wind load, so as to adjust the wind resistance status of the offshore photovoltaic system in real time.

[0032] Numerical simulation studies revealed that the influence of the guide vane 520 on the wind load on the lower surface of the photovoltaic structure is most significant. As the vertical net area of ​​the guide vane 520 increases, its wind resistance gradually improves, reducing the wind load shape coefficient of the main photovoltaic structure by more than 10%. This brings beneficial cost optimization effects to the design and optimization of offshore photovoltaic structures. When the offshore photovoltaic structure is in operation, in the event of strong winds, the guide vane 520, in its operational state, enhances the structure's wind resistance, improves its safety, prevents overturning, and provides reliable protection against economic losses.

[0033] Preferably, the predetermined included angle is 90°. This makes it easier for the wind-resistant structure 500 to remain stable when the wind load is small or there is no wind, and makes it easier to drive the deflector 520 to rotate in windy weather.

[0034] Preferably, a connecting plate 531 is installed on the wind-receiving plate 530, the connecting plate 531 is perpendicular to the wind-receiving plate 530, and the cable 540 is connected to the connecting plate 531.

[0035] refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the cable 540 and wind-receiving plate 530 of the offshore photovoltaic system in an inactive state according to an embodiment of this utility model. Figure 13 This is a schematic diagram of the cable 540 and wind-receiving plate 530 of the offshore photovoltaic system in the working state in this embodiment of the utility model. The specific weight of the load and the size of the wind-receiving plate 530 should be determined according to the preset wind load of the deflector plate 520, which can be determined according to the formula: in, The angle between the cable 540 and the connecting plate 531 of the wind-receiving plate 530 and the cable 540 is the normal angle. The angle between the horizontal wind load and the 530° normal direction of the wind-receiving panel is... The tension in the 540mm cable is equal to the weight of the object. To uniformly distribute wind load, The area of ​​the wind-receiving panel is 530. The distance between the direction of the tension in cable 540 and the parallelism of the shaft 510. The parallel distance between the center of the wind-receiving plate 530 and the rotating shaft 510.

[0036] refer to Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the connection structure of the cable 540 and the connecting plate 531 of the wind-resistant structure 500 of the offshore photovoltaic system in this embodiment of the present invention. Figure 15 This is a schematic diagram of the cable 540 of the wind-resistant structure 500 of the offshore photovoltaic system in this embodiment of the present invention. The connecting plate 531 is provided with an mounting plate 532, and the mounting plate 532 has a first connecting hole. The cable 540 includes a traction rope 541, a fixing head 542, and a connecting bolt 543. One end of the traction rope 541 is fixed with the fixing head 542, and the other end of the traction rope 541 is fixed with a weight. The fixing head 542 has a second connecting hole, and the connecting bolt 543 passes through the first connecting hole and the second connecting hole to connect the fixing head 542 and the mounting plate 532.

[0037] The wind-resistant structure 500 includes two fixed sleeves 561, which are fixedly installed on the steel truss 200, and the rotating shaft 510 is rotatably connected to the fixed sleeves 561.

[0038] The wind-resistant structure 500 also includes one or more elastic sleeves 562, which are arranged on the steel truss 200 and located between the two fixed sleeves 561. The elastic sleeves 562 are rotatably connected to the rotating shaft 510.

[0039] refer to Figure 11 The elastic sleeve 562 includes a truss connecting block 562-a, an elastic element 562-b, and a pivot support block 562-c. The truss connecting block 562-a is fixedly connected to the steel truss 200. The pivot support block 562-c is connected to the truss connecting block 562-a through the elastic element 562-b to form a pivot 510 channel. The pivot 510 is installed in the pivot 510 channel and can rotate within the pivot 510 channel. The pivot 510 support block is used to support the pivot 510. After installation, the spring sleeve is in a stretched state. Its function is to evenly apply the gravity load transmitted from the rotating shaft 510 to the steel truss 200 to various parts at the lower end of the steel truss 200, avoiding stress concentration caused by only the end fixed sleeve 561 providing support. At the same time, the spring sleeve can support the rotating shaft 510 while preventing deviations in the installation positions of multiple sleeves, or deformation due to excessive length of the rotating shaft 510, which could cause the rotating shaft 510 to jam or rotate inflexibly, thus rendering the automatic adjustment capability of the wind-resistant structure 500 ineffective and improving the stability of the wind-resistant structure 500.

[0040] The wind-resistant structure 500 also includes a limiting block 570, which is installed on the steel truss 200 to restrict the deflector plate 520 from flipping.

[0041] The wind-resistant structure 500 also includes a guide plate connecting block 580, which is fixedly connected to the guide plate 520 and rotatably connected to the rotating shaft 510.

[0042] The guide plate 520 has at least one grille hole 521, which is located at the lower part of the guide plate 520. Thus, the grille hole 521 can act as a turbulence source, reducing the wind load. Therefore, the guide plate 520 not only serves to block the wind but also to guide and turbulent the airflow. When the wind force is strong, the wind-receiving plate 530 drives the rotating shaft 510 to rotate. The guide plate 520 is then in an inclined state. The net wind-receiving area of ​​the upper part without grille holes 521 is larger than the net wind-receiving area of ​​the lower part with grille holes 521. The wind load on the guide plate 520 itself also drives the rotating shaft 510 to rotate until the wind-receiving plate 530 collides with the limiting block 570, at which point the rotating shaft 510 stops rotating.

[0043] Preferably, the grille hole 521 is located below the rotating shaft 510.

[0044] Preferably, the grille holes 521 are vertically arranged.

[0045] This embodiment also provides a marine photovoltaic system, including a plurality of vertically arranged pillars 100, a steel truss 200 arranged above the pillars 100, purlins arranged on the steel truss 200, photovoltaic panels 400 laid on the purlins, and a wind-resistant structure 500 as described in the above embodiment arranged at the lower end of the steel truss 200, wherein the pillars 100 are arranged from high to low, and the upper and lower layers of the steel truss 200 are arranged in parallel so that the photovoltaic panels 400 are inclined.

[0046] The connection between the rotating shaft 510 and the steel truss 200 is located below the photovoltaic panel 400. Thus, in the absence of wind or a light breeze, the deflector 520 does not operate, remaining nearly horizontal, and its position below the photovoltaic panel 400 prevents it from blocking sunlight.

[0047] The guide plate 520 is mainly a rectangular flat plate. Numerical simulation studies have found that the wind load shape coefficient of the offshore photovoltaic system is mainly affected by the distribution of the lower surface. Therefore, the main parts of the guide plate 520 and supporting components are arranged below the photovoltaic panel 400. When the wind is weak or there is no wind, the guide plate 520 is in a horizontal state to ensure that the photovoltaic panel 400 installed on the photovoltaic structure has sufficient sunlight to fully realize the power generation efficiency. When the wind is strong, the guide plate 520 is activated. Numerical simulation studies have found that when the guide plate 520 is in an inclined state, its guiding effect is better, and the wind load transmitted by the guide plate 520 to the main structure is also smaller, which is the most ideal state.

[0048] Preferably, the area of ​​the region on the guide plate 520 with the grille holes 521 is larger than the area without the grille holes 521. This effectively reduces the wind load on the lower part of the steel truss 200. Specifically, for example, in a 0-degree wind direction, which is the windward direction at the lower end of the steel truss 200, the wind load on the upper surface is pressure, while the wind load on the lower surface is suction. Calculations show that the wind load on the upper surface of the offshore photovoltaic system is relatively small, while the absolute value of the wind load on the lower surface is relatively large, making the lower surface the main source of wind load for the photovoltaic structure. Therefore, considering this phenomenon, the wind force above the photovoltaic panel 400 is relatively small, while the wind force below the photovoltaic panel 400 is relatively large. The main purpose of the guide plate 520 is to reduce the wind load on the lower surface of the photovoltaic panel 400. At the same time, the reason for making the upper part of the guide plate 520 smaller is to avoid the guide plate 520 being too high and blocking sunlight, which would affect the power generation efficiency of the photovoltaic system, while the lower part of the guide plate 520 will not affect the power generation efficiency.

[0049] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
