Description

Technical Field

[0001] This utility model relates to the field of wind farm operation and maintenance equipment technology, and more specifically, to a wind farm data acquisition and transmission device based on wireless communication. Background Technology

[0002] A wind farm is a wind power station composed of many wind turbine units. With the continuous expansion of installed wind farm capacity in my country and increasingly stringent requirements for reliability and operational quality to meet grid demands, optimizing the operation and maintenance of wind turbine units to generate greater economic benefits and employing scientific methods to strengthen wind farm operation and maintenance management have become increasingly important. Currently, due to the geographical location of wind farms, each site is unique, making operation and maintenance management extremely inconvenient for managers and preventing centralized management of wind farms distributed across different regions. Furthermore, power supply issues can affect the normal operation of equipment in wind farms, such as data acquisition and transmission equipment. Currently, most operation and maintenance systems rely on manual methods, which are labor-intensive, wasteful of human and material resources, have poor information feedback timeliness, and low work efficiency, failing to meet the needs of operation.

[0003] To address the aforementioned issues, Chinese Patent No. CN212724308U discloses a wind farm data acquisition and transmission device based on wireless communication. This device has sufficient power supply, which greatly improves work efficiency and ensures normal equipment operation, while also providing good performance.

[0004] This application is based on the design of the aforementioned wind farm data acquisition and transmission device based on wireless communication. All communication transmission structures and methods are the same as those in the aforementioned patent. However, the difference is that, since the aforementioned wind farm data acquisition and transmission device based on wireless communication is installed outdoors in actual use, some dust and debris will adhere to the surface of the photovoltaic panel during use. Although the photovoltaic panel itself has a certain tilt angle, it cannot completely slide off these dust and debris, resulting in residues on the outer surface of the photovoltaic panel, which will affect the light energy conversion efficiency of the photovoltaic panel.

Furthermore, the electrical control components not mentioned in this technical solution are existing technologies, and specific details can be found in the patent documents cited in the background art. For example, the base 1 has a battery structure installed inside, which is not shown in the figure and will not be described in detail here.

[0025] As attached Figure 1As shown, the rotary drive mechanism includes a first gear 11 fixedly connected to the outside of the rotating shaft 7 and located inside the protective shell 6. A second gear 12 is meshed with one side of the first gear 11 inside the protective shell 6.

[0026] As attached Figure 1-4 As shown, the tilting adjustment mechanism includes a tilting shaft 14 connected to the tilting base 8 and the connecting frame 9.

A spring 21 is connected between the bottom of the movable plate 19 and the inner wall of the movable cavity 20. A connecting block 22 is fixedly connected to the outer end of the movable plate 19. One end of the connecting block 22 extends to the fixed base 16. The base 16 is externally fixedly connected to a toggle block 23. The connection between the connecting block 22, the movable plate 19, and the toggle block 23 is welded. The outer wall of the fixed base 16 is provided with a vertical hole 24 in the vertical direction corresponding to the outer side of the connecting block 22. The vertical hole 24 communicates with the interior of the movable cavity 20. The flip adjustment mechanism is provided so that when in use, the toggle block 23 is pushed down to lower the connecting block 22 and the movable plate 19. At this time, the spring 21 is compressed, and the telescopic block 17 and the locking tooth block 18 are lowered. The operator can adjust the installation angle of the photovoltaic panel 10. During the adjustment, the flip shaft 14 and the third gear 15 will rotate. After the adjustment is completed, the toggle block 23 is released, the spring 21 returns to its original position, pushes the movable plate 19, the telescopic block 17, and the locking tooth block 18 to rise, and makes the locking tooth block 18 lock at the bottom of the third gear 15 to complete the locking, that is, the locking of the photovoltaic panel 10 after the angle adjustment is completed.

[0027] As attached Figure 1 and attached Figure 5As shown, the dust removal mechanism includes a fan 25 fixedly installed on the top of the protective shell 6. The air outlet of the fan 25 is connected to an air pipe 27, and one end of the air pipe 27 is connected to an air guide shell 26. The air guide shell 26 is fixedly installed on the top of the photovoltaic panel 10, and an air outlet slit 28 is provided on the top of the air guide shell 26 near the upper surface of the photovoltaic panel 10. The dust removal mechanism facilitates the blowing off of some dust or debris attached to the outer surface of the photovoltaic panel 10 during use, reducing the impact of debris attached to the surface of the photovoltaic panel 10 on the light energy conversion efficiency.

[0028] Working principle: This utility model designs a wind farm data acquisition and transmission device based on wireless communication. The specific structure is shown in the attached instruction manual. Figure 1-5 As shown, in this technical solution, the photovoltaic panel 10 and the use of a wireless network for communication and data transmission provide sufficient power to the electrical components in the data acquisition and transmission device, facilitating better monitoring of the wind turbine operating status in the wind farm. Furthermore, by setting up a signal receiving and processing box 2 for wireless connection with the data acquisition module built into the data acquisition box installed on the wind turbine casing, and wirelessly connecting the signal receiving and processing box 2 to a control box 3, which in turn is wirelessly connected to a remote terminal, real-time monitoring of the wind turbine operating status and environment in the wind farm is possible. This allows staff to remotely monitor the collected and transmitted data from the wind turbine. Simultaneously, by setting up a rotation drive mechanism and a flip adjustment mechanism, it is convenient to control the rotation of the rotating shaft 7 horizontally by controlling the motor 13 to drive the second gear 12, which in turn drives the first gear 11, thus facilitating adjustment of the photovoltaic panel 10's installation direction as needed. The flip adjustment mechanism allows for easy adjustment by first pushing the toggle block 23 downwards to lower the belt. The moving connecting block 22 and the movable plate 19 descend, at which point the spring 21 is compressed, and the telescopic block 17 and the locking tooth block 18 descend. The operator can then adjust the installation angle of the photovoltaic panel 10. During the adjustment process, the flip shaft 14 and the third gear 15 will rotate. After the adjustment is completed, the toggle block 23 is released, and the spring 21 returns to its original position, pushing the movable plate 19, the telescopic block 17, and the locking tooth block 18 upward. This causes the locking tooth block 18 to engage with the bottom of the third gear 15, thus locking the photovoltaic panel 10 after angle adjustment. The flexible adjustment of the installation direction and angle of the photovoltaic panel 10 can meet the installation requirements of different outdoor locations. Furthermore, by setting up a dust removal mechanism, during use, the fan 25 is controlled to run and compress external air, which flows into the air guide shell 26 through the air pipe 27 and is blown out from the air outlet 28 at the top of the photovoltaic panel 10 to blow air onto the upper surface of the photovoltaic panel 10. This facilitates the removal of dust or debris adhering to the outer surface of the photovoltaic panel 10 during use, reducing the impact of debris on the light energy conversion efficiency.
