Description

Technical Field

[0001] This utility model relates to the field of photovoltaic device technology, specifically a flexible photovoltaic device for auxiliary power generation on the outside of a wind turbine tower. Background Technology

[0002] When a wind turbine is running, a portion of the electricity it generates powers its auxiliary systems. However, in windless conditions, some internal systems need to continue operating, requiring power from the grid, making the turbine a net energy consumer. Combining flexible solar panels with the wind turbine tower base can improve the turbine's operating efficiency because these solar panels can still provide the necessary power to the turbine's internal systems even when there is no wind. The system works by converting solar energy into electrical energy, which is then directly distributed to DC loads via a controller or converted to AC loads via an inverter. Adding batteries to the system stores excess electricity, ensuring that the internal systems can still be powered even when the turbine is idle and the solar panels are not generating electricity. Currently, flexible solar panels are a mature technology with excellent performance and are widely used in building-integrated photovoltaics (BIPV).

[0003] Currently, flexible photovoltaic (PV) panels are technologically mature and perform well, and have been widely used in the field of building-integrated photovoltaics (BIPV). However, there are relatively few cases of combining them with wind turbine towers, and significant technical problems exist in practical applications. The following technical issues need to be considered when installing flexible solar cells on vertical buildings or towers to install photovoltaic power generation devices:

[0004] (1) The design and installation should take into account the influence of the solar incident angle. The solar incident angle determines the installation angle of the photovoltaic panel. For tropical and subtropical regions near the equator, the sunlight is better in the morning or afternoon. However, due to the direct sunlight at noon, it is difficult for vertically installed photovoltaic panels to receive sunlight directly. Therefore, the utilization of light resources is extremely limited, resulting in a reduction in the solar intensity and the amount of sunlight received by the photovoltaic panel, which reduces the utilization efficiency of the photovoltaic panel.

[0005] (2) Since the tower is cylindrical, the wind will blow directly onto the surface of the photovoltaic panel during windy weather, and the photovoltaic panel is prone to detach from the surface of the tower and be damaged. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a flexible photovoltaic device for auxiliary power generation on the outside of a wind turbine tower. This solves the problem mentioned in the background section: direct sunlight at midday makes it difficult for vertically installed photovoltaic panels to receive direct sunlight, resulting in extremely limited utilization of solar resources, reduced solar intensity and duration received by the photovoltaic panels, and decreased utilization efficiency. Furthermore, because the tower is cylindrical, strong winds can directly blow onto the surface of the photovoltaic panels during windy weather, causing them to easily detach from the tower surface and become damaged.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a flexible photovoltaic device for auxiliary power generation outside a wind turbine tower, comprising:

[0010] The wind turbine tower has flexible photovoltaic panels wrapped on both sides, and the flexible photovoltaic panels are all semi-cylindrical in design.

[0011] Mounting bases are provided on the upper and lower surfaces of the flexible photovoltaic panel, and connecting rods are installed on both the front and back of the mounting bases;

[0012] Mounting brackets are installed on the upper and lower sides of the wind turbine tower. Motors are mounted on the surface of the mounting brackets. Lead screws are coaxially mounted on the rotors of the motors. Adjusting blocks are screwed onto the surface of the lead screws.

[0013] Fixed blocks are disposed on both sides of the surface of the above-mentioned adjusting block, and a first mounting ring is installed at the bottom of each adjusting block. The first mounting ring is sleeved on the outer periphery of the above-mentioned connecting rod.

[0014] The second mounting block is disposed on both sides of the surface of the lower adjusting block. The upper surface of the second mounting block is equipped with a second mounting ring. The inner cavity of the second mounting ring is inserted with a mounting rod. Both ends of the mounting rod are equipped with connecting plates. The upper surface of the connecting plate is equipped with a third mounting ring. The third mounting ring is sleeved on the outer periphery of the lower connecting rod.

[0015] Preferably, each of the adjustment blocks is equipped with a slider, and the surface of the mounting bracket is provided with a groove corresponding to the slider. The slider is inserted into the groove so that the adjustment block can move linearly.

[0016] Preferably, each surface of the mounting frame is equipped with a mounting plate, and each surface of the mounting plate is equipped with a mounting clamp. The mounting clamp can fix the mounting plate to the surface of the wind turbine tower, thereby fixing the mounting frame.

[0017] Preferably, the surface of the mounting hoop is evenly provided with threaded rods, and the threaded rods are all screwed onto the surface of the wind turbine tower, so that the mounting hoop can be installed on the surface of the wind turbine tower through the threaded rods.

[0018] Preferably, the upper and lower parts of both sides of the wind turbine tower are provided with mounting grooves, and the inner side of the mounting frame is provided with fixing plates. The fixing plates are embedded in the mounting grooves and can support the inner side of the mounting frame.

[0019] Preferably, bolts are screwed onto the four corners of the surface of the fixing plate. The bolts penetrate the fixing plate and are screwed onto the inner wall of the mounting groove. The fixing plate can be fixed by the bolts, thereby fixing the mounting frame.

[0020] Beneficial effects

[0021] Compared with the prior art, this utility model provides a flexible photovoltaic device for auxiliary power generation on the outside of a wind turbine tower, which has the following beneficial effects:

[0022] 1. The flexible photovoltaic device for auxiliary power generation on the outside of the wind turbine tower is designed with a semi-cylindrical design, which can wrap around the surface of the wind turbine tower and fit tightly to the surface of the wind turbine tower. This reduces the wind force on the flexible photovoltaic panel and allows the wind force to flow out along the surface of the flexible photovoltaic panel, preventing the flexible photovoltaic panel from falling off the surface of the wind turbine tower and being damaged.

[0023] 2. The flexible photovoltaic device for auxiliary power generation outside the wind turbine tower is equipped with a motor that drives a lead screw to rotate, thereby moving an adjusting block and ultimately the entire flexible photovoltaic panel. Starting the lower motor causes the lower part of the flexible photovoltaic panel to move, tilting it around the first mounting ring as an axis. The connecting plate also changes its tilt angle as the lower adjusting block moves, pulling the lower part of the flexible photovoltaic panel and causing it to tilt. This allows the flexible photovoltaic panel to receive sunlight even when the sun is directly overhead at noon, increasing the solar intensity and duration of sunlight exposure and improving the utilization efficiency of the photovoltaic panel.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides a technical solution: a flexible photovoltaic device for auxiliary power generation outside a wind turbine tower. (See also...) Figure 1 The wind turbine tower 1 is wrapped with flexible photovoltaic panels 2 on both sides of the wind turbine tower 1. The flexible photovoltaic panels 2 are all semi-cylindrical designs.

[0033] Please see Figure 2 Mounting base 3 is set on the upper and lower surfaces of flexible photovoltaic panel 2, and connecting rod 4 is installed on both the front and back of mounting base 3;

[0034] Please see Figure 1 Mounting brackets 5 are installed on the upper and lower sides of the wind turbine tower 1. Motors 6 are mounted on the surface of each mounting bracket 5. Please refer to [link / reference]. Figure 3 Each rotor of motor 6 is coaxially mounted with a lead screw 7, and each lead screw 7 is screwed with an adjusting block 8.

[0035] Fixed blocks 9 are provided on both sides of the surface of the upper adjusting block 8. The bottom of each adjusting block 8 is equipped with a first mounting ring 10, and the first mounting ring 10 is sleeved on the outer periphery of the upper connecting rod 4.

[0036] Please see Figure 4The second mounting block 11 is disposed on both sides of the surface of the lower adjusting block 8. The upper surface of the second mounting block 11 is equipped with a second mounting ring 12. The inner cavity of the second mounting ring 12 is inserted with a mounting rod 13. The two ends of the mounting rod 13 are equipped with connecting plates 14. The upper surface of the connecting plate 14 is equipped with a third mounting ring 15. The third mounting ring 15 is sleeved on the outer periphery of the lower connecting rod 4.

[0037] The flexible photovoltaic panel 2 is designed as a semi-cylindrical design, which can wrap around the surface of the wind turbine tower 1 and fit tightly to the surface of the wind turbine tower 1. This reduces the wind force on the flexible photovoltaic panel 2, allowing the wind force to flow out along the surface of the flexible photovoltaic panel 2, thus preventing the flexible photovoltaic panel 2 from falling off the surface of the wind turbine tower 1 and being damaged.

[0038] The starting motor 6 drives the lead screw 7 to rotate, which in turn moves the adjusting block 8, thereby moving the flexible photovoltaic panel 2 as a whole. Starting the lower motor 6 causes the lower part of the flexible photovoltaic panel 2 to move, causing it to tilt around the first mounting ring 10. The connecting plate 14 also changes its tilt angle as the adjusting block 8 moves. The connecting plate 14 can rotate around the second mounting ring 12, thus pulling the lower part of the flexible photovoltaic panel 2. During this pulling, the connecting plate 14 becomes taut, preventing any obstruction to the tilt of the flexible photovoltaic panel 2. This allows the flexible photovoltaic panel 2 to receive sunlight even when the sun is directly overhead at noon, increasing the solar intensity and duration of sunlight exposure, and improving the utilization efficiency of the photovoltaic panel.

[0039] The surface of the adjusting block 8 is equipped with sliders 16, and the surface of the mounting bracket 5 is provided with grooves 17 corresponding to the sliders 16. The sliders 16 are inserted into the grooves 17, so that the adjusting block 8 can move linearly.

[0040] Mounting bracket 5 is equipped with mounting plates 18 on its surface, and mounting clamps 19 are installed on the surface of mounting plates 18. The mounting plates 18 can be fixed to the surface of the wind turbine tower 1 by means of the mounting clamps 19.

[0041] The mounting clamp 19 is evenly provided with threaded rods 20, which are screwed onto the surface of the wind turbine tower 1. The mounting clamp 19 can be installed on the surface of the wind turbine tower 1 through the threaded rods 20.

[0042] Please see Figure 6 The wind turbine tower 1 has mounting slots 21 on both the upper and lower parts of its sides. Please refer to [link / reference]. Figure 5 The mounting bracket 5 is equipped with a fixing plate 22 on its inner side. The fixing plate 22 is embedded in the mounting groove 21 and can support the inner side of the mounting bracket 5.

[0043] Bolts 23 are screwed onto the four corners of the surface of the fixing plate 22. The bolts 23 penetrate the fixing plate 22 and are screwed onto the inner wall of the mounting groove 21. The fixing plate 22 can be fixed by the bolts 23, thereby fixing the mounting bracket 5.

[0044] The working process of this device is as follows: First, by designing the flexible photovoltaic panel 2 as a semi-cylindrical shape, it can wrap around the surface of the wind turbine tower 1 and fit tightly against the surface of the wind turbine tower 1, reducing the wind force on the flexible photovoltaic panel 2. This allows the wind force to flow along the surface of the flexible photovoltaic panel 2, preventing the flexible photovoltaic panel 2 from detaching from the surface of the wind turbine tower 1 and being damaged. Then, starting the motor 6 drives the lead screw 7 to rotate, which in turn moves the adjusting block 8, thereby moving the flexible photovoltaic panel 2 as a whole. Finally, starting the lower motor 6 rotates the lower part of the flexible photovoltaic panel 2. As the flexible photovoltaic panel 2 moves, it tilts around the first mounting ring 10 as an axis. The connecting plate 14 also changes its tilt angle as the adjusting block 8 moves below. The connecting plate 14 can rotate around the second mounting ring 12, thereby pulling the lower part of the flexible photovoltaic panel 2. When pulled, the connecting plate 14 will also tighten, thus not hindering the tilt of the flexible photovoltaic panel 2. This allows the flexible photovoltaic panel 2 to receive sunlight even when the sun is directly overhead at noon, increasing the solar intensity and duration of sunlight received by the flexible photovoltaic panel 2, and improving the utilization efficiency of the photovoltaic panel.
