[0021] With the promotion of renewable energy, photovoltaic power generation technology has been widely applied in various scenarios. The integrity of the photovoltaic power generation array is a crucial factor in whether the designed power generation efficiency can be effectively achieved. Traditional photovoltaic power generation technology generally uses fixed solar panels for power generation. Although it can produce clean energy, it also has some significant drawbacks: It is susceptible to severe weather conditions. Strong typhoons, severe convective rainstorms, hail, sandstorms, and other severe weather events can easily damage fixed solar panels, increasing maintenance costs and risks; cleaning efficiency is low, especially in desert areas, where untimely cleaning will reduce the power generation efficiency of solar panels; it has adverse effects on the aquatic ecosystem. Densely piling fixed solar panels in some fishponds can affect water flow and heat dissipation, thus impacting the aquaculture environment.

[0022] In view of this, the present invention provides an adjustable photovoltaic power generation device 100. Figures 1 to 3 An embodiment of the adjustable photovoltaic power generation device 100 provided by this utility model.

[0023] Please see Figures 1 to 3 The adjustable photovoltaic power generation device 100 includes a mounting frame 1, a protective cover 2, a telescopic support 3, a photovoltaic power generation module 4, and a spray assembly 5. The mounting frame 1 extends along a first direction and has a first end and a second end. The protective cover 2 is mounted on the mounting frame 1 and is located at the first end of the mounting frame 1. The protective cover 2 has an inlet and outlet facing the second end. The telescopic support 3 is mounted on the mounting frame 1 and can extend and retract along the first direction. The telescopic support 3 has a fixed end and a movable end. The fixed end is fixedly installed inside the protective cover 2, and the movable end can be subjected to force and extend outside the protective cover 2 or retract inside the protective cover 2 through the inlet and outlet. The photovoltaic power generation module 4 includes multiple solar panels 41 for absorbing solar energy and converting it into electrical energy. The multiple solar panels 41 are mounted on the telescopic support 3 and can move inside and outside the protective cover 2 under the action of the telescopic support 3. The spray assembly 5 includes multiple spray heads 51, which are located inside the protective cover 2 for cleaning the photovoltaic power generation module 4 inside the protective cover 2.

[0024] In this utility model, the photovoltaic power generation module 4 can move inside and outside the protective cover 2 under the action of the telescopic bracket 3, and the protective cover 2 is equipped with a spray assembly 5. Thus, in the event of severe weather such as strong typhoons, severe convective rainstorms, hail, and sandstorms, the telescopic bracket 3 causes the photovoltaic power generation module 4 to retract inside the protective cover 2, providing effective protection for the photovoltaic power generation module 4 and the telescopic bracket 3, reducing the risk of damage to the photovoltaic power generation module 4 and the telescopic bracket 3 and the cost of maintenance. When there is a lot of dust on the photovoltaic power generation module 4, the telescopic bracket 3 causes the photovoltaic power generation module 4 to retract inside the protective cover 2, and it is rinsed by the spray head 51, improving the cleaning efficiency and ensuring the power generation efficiency of the photovoltaic power generation module 4. When the adjustable photovoltaic power generation device 100 is installed in an aquaculture area and the light intensity of the aquaculture area is low, the telescopic bracket 3 causes the photovoltaic power generation module 4 to retract inside the protective cover 2, avoiding blocking sunlight from reaching the aquaculture area, so as to maximize the natural light entering the water and improve the light intensity.

[0025] It should be noted that when the adjustable photovoltaic power generation device 100 is installed in the aquaculture water area, the state of the photovoltaic power generation component 4 can be switched according to the actual power generation and aquaculture needs through the telescopic bracket 3, so as to realize the dynamic adjustment of the light in the aquaculture water area, solve the adverse effects of fixed photovoltaic panels on the growth of aquaculture organisms, improve aquaculture efficiency and yield, and optimize energy utilization efficiency.

[0026] Furthermore, the adjustable photovoltaic power generation device 100 also includes a drive component, which is drivenly connected to the movable end of the telescopic bracket 3 to drive the movable end to move along the first direction, thereby reducing manual labor intensity.

[0027] Furthermore, the adjustable photovoltaic power generation device 100 also includes a monitoring component, which includes a light sensor, a wind speed sensor, and a rainfall sensor. The light sensor is used to measure the intensity of sunlight, the wind speed sensor is used to measure wind speed, and the rainfall sensor is used to measure precipitation and precipitation intensity. Based on the measurement results, real-time weather can be identified. In this way, the state of the telescopic support 3 and the photovoltaic power generation component 4 can be adjusted according to the monitoring results of the monitoring component to cope with severe weather such as strong typhoons, severe convective rainstorms, hail, and sandstorms, and to protect the telescopic support 3 and the photovoltaic power generation component 4.

[0028] Of course, the telescopic bracket 3 can be operated manually or automatically.

[0029] Furthermore, the adjustable photovoltaic power generation device 100 also includes a photovoltaic controller, which is electrically connected to the drive component and the monitoring component to control the state of the drive component according to the monitoring results of the monitoring component, thereby controlling and adjusting the telescopic bracket 3 and the photovoltaic power generation component 4 in real time.

[0030] More specifically, the photovoltaic controller is an SCU-7323 photovoltaic controller (China Electronics Technology Group Corporation). The SCU-7323 photovoltaic controller is electrically connected to the solar panel, battery, monitoring component, and drive component through a communication interface (such as RS485). It can send control signals to the drive component according to actual needs, such as power regulation commands and environmental monitoring data. That is, it sends signals to control the state of the drive component based on the monitoring results of the monitoring component. The control program algorithms involved are all existing technologies and will not be described in detail here.

[0031] More specifically, in one embodiment of this invention, when the light intensity measured by the light sensor is higher than 10000 lux and the wind speed measured by the wind speed sensor is lower than 35 m / s, the photovoltaic controller controls the drive assembly to drive the telescopic bracket 3 to extend to its maximum. When the wind speed measured by the wind speed sensor is higher than 35 m / s or the rain sensor measures heavy rainfall, the photovoltaic controller controls the drive assembly to drive the telescopic bracket 3 to retract into the protective cover 2 and fix it in place.

[0032] For details, please refer to Figure 1 and Figure 2 The telescopic bracket 3 includes two support groups arranged opposite each other along a second direction. Each support group includes a plurality of X-shaped brackets 31 arranged sequentially along a first direction. Each X-shaped bracket 31 includes two connecting rods arranged in a cross configuration and hinged together at the middle. The two connecting rods of each X-shaped bracket 31 are respectively hinged one-to-one with the two connecting rods of its adjacent X-shaped bracket 31. The corresponding two connecting rods in the two X-shaped brackets 31 arranged opposite each other in the two support groups are connected one-to-one with the two ends of a solar panel 41. One connecting rod of the X-shaped bracket 31 located at the fixed end of each support group is hinged to the protective cover 2, and the other connecting rod is hinged to the mounting frame 1. The driving assembly is driven by the connecting rod located at the movable end of the two support groups to drive the two support groups to move along the first direction, so that the two support groups extend outside the protective cover 2 or retract inside the protective cover 2. The first direction and the second direction are perpendicular to each other in the plane.

[0033] Furthermore, the driving assembly includes two driving mechanisms 6, which are arranged opposite to each other along the second direction, and each driving mechanism 6 is connected to one of the two bearing groups in a corresponding driving connection to drive the two bearing groups to move along the first direction. In this way, the telescopic bracket 3 is subjected to uniform force, preventing it from jamming due to uneven force during movement.

[0034] For further details, please refer to Figures 1 to 3 Each of the drive mechanisms 6 includes a motor assembly 61, a pulley assembly 62, and a connecting rope 63. The motor assembly 61 includes a first drive motor 611 and a second drive motor 612. The rotation direction of the output shaft of the first drive motor 611 is the same as the rotation direction of the output shaft of the second drive motor 612, and the rotation speed of the output shaft of the first drive motor 611 is the same as the rotation speed of the output shaft of the second drive motor 612. The pulley assembly 62 includes a first pulley 621 and a second pulley 622. The first pulley 621 is located at the first end of the mounting bracket 1, and the second pulley 622... Located at the second end of the mounting frame 1; the connecting rope 63 is connected to the movable end of its corresponding bearing assembly, one end of the connecting rope 63 is wound around the first pulley 621 and connected to the first drive motor 611, and the other end of the connecting rope 63 is wound around the second pulley 622 and connected to the second drive motor 612, so that the first drive motor 611 and the second drive motor 612 drive the connecting rope 63 to extend or retract the bearing assembly; the output shafts of the two first drive motors 611 in the two drive mechanisms 6 rotate in the same direction and at the same speed.

[0035] Thus, each of the bearing groups can extend outside the protective cover 2 or retract inside the protective cover 2 under the action of a motor group 61 and a connecting rope 63, and the output parameters of the two motor groups 61 are the same, ensuring that the telescopic bracket 3 can move smoothly as a whole.

[0036] Specifically, the drive motor in the motor assembly 61 can achieve an IP65 protection rating.

[0037] Specifically, each of the motor units 61 further includes a protective cover, within which the first drive motor 611 and the second drive motor 612 are housed. The protective cover protects the structure of the first drive motor 611 and the second drive motor 612 from environmental corrosion. More specifically, the protective cover is made of polyimide fiber.

[0038] Specifically, each solar panel 41 is rotatably mounted on its corresponding connecting rod, meaning that the solar panel 41 can rotate relative to the connecting rod to adjust its elevation angle and maximize solar energy harvesting. More specifically, the solar panel is rotatably connected to the connecting rod via a rotating shaft.

[0039] For details, please refer to Figure 1 and Figure 2 The adjustable photovoltaic power generation device 100 also includes a water circulation component, which includes a water storage tank 7, a water pump 8, and a water treatment tank. The water storage tank 7 is used to store clean water. One end of the water pump 8 is connected to the water storage tank 7, and the other end is connected to the spray head 51 through a first water inlet pipe. The water treatment tank is used to treat sewage to form the clean water. The water treatment tank is connected to the bottom wall of the protective cover 2 through a second water inlet pipe and to the water storage tank 7 through an outlet pipe to input the clean water into the water storage tank 7 for storage.

[0040] In this way, the wastewater after cleaning the telescopic bracket 3 and the photovoltaic power generation module 4 falls to the bottom wall of the protective cover 2 and flows through the second water inlet pipe to the water treatment tank for treatment (for example, the water treatment tank is equipped with a filter screen for filtration) to form clean water, realizing the repeated recycling of water resources. This not only saves a lot of precious water resources, especially in arid areas, but also reduces cleaning costs and labor intensity.

[0041] Furthermore, the adjustable photovoltaic power generation device 100 also includes a temperature sensor and a photovoltaic controller. The temperature sensor is used to monitor the temperature (at night), and the photovoltaic controller is electrically connected to the temperature sensor and the spray assembly 5. Thus, spraying can be performed when the nighttime temperature reaches or falls below a preset temperature, at which point water evaporation is minimal, further saving water resources.

[0042] Specifically, the mounting frame 1, the protective cover 2, and the telescopic bracket 3 are all polyimide fiber components. That is to say, the mounting frame 1, the protective cover 2, and the telescopic bracket 3 are all made of polyimide fiber composite material. Polyimide fiber composite material has excellent corrosion resistance, weather resistance, high strength, and low density, making it very suitable for long-term use in desert areas and corrosive marine environments. It also has a high elastic modulus and can withstand motion loads (repeated telescopic movements) and external loads. In this way, the adjustable photovoltaic power generation device 100 can be guaranteed to operate stably for a long time in harsh environments.

[0043] More specifically, polyimide fiber composites can be polyimide basalt fiber composites or polyimide glass fiber composites.

[0044] For details, please refer to Figures 1 to 3A concrete base 9 is also provided below the mounting frame 1 to improve the stability of the adjustable photovoltaic power generation device 100.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
