Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification, in particular to a dehumidification device for a variable pitch system. Background Art

[0002] In the field of wind power generation, the pitch system is a key component for adjusting the angle of wind turbine blades and is crucial to the power output and stable operation of wind turbines. The pitch system equipment box, as an enclosed space housing key components such as the control system, power module, and communications equipment, has a stable internal environment that directly impacts the performance and lifespan of the entire system. Especially in harsh outdoor environments such as high temperature, humidity, and salt spray, moisture can easily accumulate inside the equipment box, causing corrosion, short circuits, and even system failures. Therefore, an effective dehumidification mechanism is crucial for maintaining a suitable humidity environment within the equipment box, ensuring the normal operation of electronic components, and extending the lifespan of the equipment.

[0003] A dehumidification device for a variable pitch system is disclosed in the patent with publication number CN213235332U. The utility model relates to the technical field of dehumidification of variable pitch systems, including a variable pitch system housing, an exhaust hole is provided on the top of the variable pitch system housing, and an installation groove is provided inside the variable pitch system housing, a second fan cover is installed on the top side of the variable pitch system housing, and a first fan cover is installed on the bottom side of the variable pitch system housing, fans are installed inside the first and second fan covers, and box bodies are installed at the ends of the first and second fan covers. The utility model solves the problem that the hot air provided by the dehumidification device will increase the internal temperature of the variable pitch system by arranging a first air duct and a second air duct on the variable pitch system housing, and solves the problem that the position of the hot air blowing to the inside of the variable pitch system remains unchanged, resulting in uneven heating inside the variable pitch system by arranging an exhaust duct in the variable pitch system housing.

[0004] The aforementioned patent uses an electric heating wire to directly heat and blow air into the chamber. While this method can raise the temperature inside the chamber and reduce moisture condensation to a certain extent, it has significant limitations. First, simply blowing hot air into the chamber often only converts moisture into water vapor, but fails to effectively expel it from the chamber. Over time, the humidity inside the chamber remains high, which can easily lead to internal corrosion of the equipment. Furthermore, the high-temperature gas generated by the electric heating wire blowing toward electronic components may exceed their tolerance temperature, accelerating aging and even causing failures, reducing system reliability and safety.

[0005] Therefore, the present application proposes a dehumidification device for a pitch system to solve the above problems. Utility Model Content

A heat dissipation pipe 16 is provided on the left side of the system control box 2. The heat dissipation pipe 16 is S-shaped as a whole. The upper and lower ends of the heat dissipation pipe 16 are connected to the air intake pipe 15. A temperature and humidity detection sensor 22 is provided on the side wall of the air intake pipe 15 close to the drying box 7.

After the treatment, the temperature and humidity are detected by the temperature and humidity detection sensor 22 on the intake pipe 15. When the detected humidity is still high, the power of the electric heating wire 12 is adjusted to ensure effective drying. At the same time, when the temperature is detected to be high, the intake solenoid valve 19 is closed, the heat dissipation solenoid valve 18 is opened, and the high-temperature gas is introduced into the heat dissipation pipe 16 for heat dissipation, thereby reducing the gas temperature; the intake solenoid valve 3 21 is closed, and the intake solenoid valve 2 20 is opened, and the cooled dry gas is passed through the intake pipe 2 17 into the upper end action box 13, which does not affect the extraction of moisture below. This device uses the vacuum pump 6, the vacuum pipe 29 and the lower end working box 13 to extract the humidity from the box, preventing moisture from accumulating in the box. After passing through the drying box 7, the device performs a drying process, and uses the temperature and humidity detection sensor 1 22 and the temperature and humidity detection sensor 2 23 to detect the temperature and humidity of the dried gas, thereby preventing the temperature and humidity of the gas entering the box from being too high, thereby ensuring the normal operation of the electronic components in the box. The device is also provided with a vacuum pipe 18. When the temperature in the box is too high, when the vacuum pump 6 and the vacuum pipe 18 are working, the electric heating wire 12, the vacuum solenoid valve 2 11, the air intake solenoid valve 19 and the air intake solenoid valve 2 20 are closed, and the high-temperature gas passes through the drying box 7 and enters the heat dissipation pipe 16. The high-temperature gas contacts the heat dissipation pipe 16 through the heat conduction plate 29 inside the heat dissipation pipe 16, and effectively dissipates heat through the heat dissipation pipe 16. The temperature is detected by the temperature and humidity detection sensor 2 23. The heat dissipated gas is introduced into the lower end working box 13 through the air intake pipe 15, thereby realizing the airflow heat dissipation cycle in the system control box 2.

[0029] Several heat conducting plates 29 are fixedly connected to the inner wall of the heat dissipation pipe 16. When the high temperature gas passes through the heat dissipation pipe 16, the gas contacts the heat conducting plates 29, which facilitates the heat transfer to the heat dissipation pipe 16 through the heat conducting plates 29, making heat dissipation more convenient.

[0030] The upper and lower inner walls of the system control box 2 are fixedly connected with the action box 13, and the adjacent side walls of the two action boxes 13 are provided with vents 14. The exhaust pipe 1 8 is connected to the upper action box 13, the exhaust pipe 2 9 is connected to the lower action box 13, and the lower end of the intake pipe 15 is connected to the lower action box 13. The left side wall of the upper action box 13 is fixedly connected with the intake pipe 2 17. The end of the intake pipe 2 17 away from the action box 13 passes through the left side wall of the system control box 2 and is connected to the intake pipe 15. The connection between the intake pipe 2 17 and the intake pipe 15 is located at the intake An air intake solenoid valve 20 is provided on the air intake pipe 17 between the solenoid valve 3 21 and the connection between the lower end of the heat dissipation pipe 16 and the air intake pipe 1 15. During dehumidification, the lower end action box 13 is used to extract moisture, and the upper end action box 13 is used to introduce dry gas; during heat dissipation, the lower end action box 13 is used to introduce the gas after heat dissipation, and the upper end action box 13 is used to extract hot gas. Since moisture has a high water content and a high density, it generally stays at the bottom, while hot air generally stays at the top. Therefore, the functions of the upper and lower action boxes 13 are changed in different situations to achieve better dehumidification and heat dissipation effects.

[0031] The shock-absorbing plate 3 adopts a hollow structure design. Two auxiliary plates 4 are provided on the upper and lower sides of the system control box 2. The auxiliary plates 4 are fixed to the front side ends of the fixed plate 1. A buffer mechanism 5 is provided between the auxiliary plates 4 and the system control box 2. When the external environment vibrates, the hollow shock-absorbing plate 3 and the buffer mechanism 5 connected by the universal joint can ensure that the system control box 2 can move in different directions, thereby effectively absorbing and alleviating the impact of external vibration on the system control box 2, protecting the internal components of the system from damage, and improving the reliability and service life of the device.

[0032] The buffer mechanism 5 includes a sliding rod 24 and a buffer cylinder 25. The end of the sliding rod 24 away from the system control box 2 is connected to the side wall of the auxiliary plate 4 through a universal joint. The end of the buffer cylinder 25 away from the auxiliary plate 4 is connected to the system control box 2 through a universal joint. The end of the sliding rod 24 away from the auxiliary plate 4 passes through the side wall of the buffer cylinder 25 close to the auxiliary plate 4 and is fixedly connected to a sliding plate 26. The sliding plate 26 is slidably connected to the buffer cylinder 25. An upper buffer spring 27 is provided on the side of the sliding plate 26 close to the auxiliary plate 4. The upper buffer spring 27 is sleeved on the sliding rod 24. The two ends of the upper buffer spring 27 are respectively connected to the sliding plate 26 close to the auxiliary plate 4 and the buffer cylinder 25. It is fixedly connected to the inner wall of the auxiliary plate 4, and the sliding plate 26 is fixedly connected to the side away from the auxiliary plate 4 with a lower buffer spring 28. The end of the lower buffer spring 28 away from the sliding plate 26 is fixedly connected to the inner wall of the buffer tube 25 away from the auxiliary plate 4. When the system control box 2 vibrates in the external environment, the corresponding position movement occurs between the system control box 2 and the fixed plate 1. At this time, the sliding rod 24 drives the sliding plate 26 to slide in the buffer tube 25. Under the action of the upper buffer spring 27 and the lower buffer spring 28, the force between the fixed plate 1 and the system control box 2 is buffered, thereby reducing the vibration of the electronic components in the system control box 2 and ensuring the normal operation of the equipment.

[0033] Working principle: When the system control box 2 is dehumidified, the exhaust solenoid valve 10 is closed and the exhaust solenoid valve 2 11 is opened. The exhaust pump 6, the exhaust pipe 2 9 and the lower end action box 13 are used to extract the moisture that has sunk to the bottom of the box. When passing through the drying box 7, the electric heating wire 12 is used to dry the moisture. After treatment, the temperature and humidity are detected by the temperature and humidity detection sensor 22 on the intake pipe 15. When the detected humidity is still high, the power of the electric heating wire 12 is adjusted to ensure effective drying. At the same time, when the temperature is detected to be high, the intake solenoid valve 19 is closed and the heat dissipation solenoid valve 18 is opened to introduce the high-temperature gas into the heat dissipation pipe 16 for heat dissipation, thereby reducing the gas temperature; the intake solenoid valve 3 21 is closed and the intake solenoid valve 2 20 is opened to allow the cooled dry gas to enter the upper end action box 13 through the intake pipe 2 17 without affecting the extraction of moisture below. The device uses a vacuum pump 6, a vacuum pipe 29, and a lower working box 13 to extract humidity from the chamber, preventing moisture from accumulating inside the chamber. After passing through the drying chamber 7, the air is dried, and the temperature and humidity of the dried air are detected by temperature and humidity sensors 1 22 and 23, thereby preventing excessively high temperatures and humidity levels in the air entering the chamber, thereby ensuring the normal operation of the electronic components within the chamber. The device also includes a vacuum pipe 18. When the chamber temperature is too high, the vacuum pump 6 and vacuum pipe 18 operate, closing the electric heating wire 12, the vacuum solenoid valve 2 11, the air inlet solenoid valve 19, and the air inlet solenoid valve 20. The hot air passes through the drying chamber 7 and enters the heat dissipation pipe 16. The hot air contacts the heat conduction plate 29 inside the heat dissipation pipe 16, effectively dissipating heat through the heat dissipation pipe 16. The temperature of the hot air is detected by temperature and humidity sensors 23, and the heat dissipated air is introduced into the lower working box 13 through the air inlet pipe 15, thereby completing the airflow heat dissipation cycle within the system control box 2. A shock-absorbing plate 3 and a buffer mechanism 5 are also provided between the system control box 2 and the fixed plate 1. When the external environment vibrates, the hollow shock-absorbing plate 3 and the buffer mechanism 5 connected by the universal joint allow the system control box 2 to move in different directions, thereby effectively absorbing and alleviating the impact of external vibrations on the system control box 2, protecting the internal components of the system from damage, and improving the reliability and service life of the device.
