Abstract
Description
Technical Field

[0002] With the ever-increasing global demand for renewable energy, wind power, as a clean and environmentally friendly energy source, has been widely adopted. Wind turbines are typically installed in areas rich in wind resources, which are often accompanied by low-temperature environments, especially in winter. Extremely low temperatures can cause critical components of wind turbines, such as blades, casings, and transmission systems, to freeze. This not only hinders normal power generation but can also cause serious damage to the equipment. Therefore, antifreeze and defrosting technologies are indispensable to ensure the reliability and efficiency of wind turbines in cold climates.
[0003] Existing wind turbine antifreeze and defrosting solutions sometimes employ direct heating or antifreeze to prevent freezing. However, direct heating can lead to uneven heating and cooling of the turbine surface, generating internal expansion and contraction stresses that can damage the equipment structure. Antifreeze, on the other hand, is costly, complex to maintain, and poses potential environmental pollution problems. Furthermore, traditional energy storage systems often rely on external power sources. In the absence of grid connection or when the power supply is unstable, it is difficult to ensure the effective operation of the defrosting components, limiting the independent operation capability of the wind turbine.

The following provides a detailed description of this automatic antifreeze and defrost wind turbine. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments.
[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0025] Example 1
[0026] Please see Figure 1-5This embodiment provides an automatic antifreeze and defrost wind turbine, comprising: a wind turbine 1, with a power generation mechanism 101 inside for generating wind power; a defrost assembly located at the bottom of the wind turbine 1 for heating and defrosting the outer casing; and an energy storage assembly located on one side of the top of the wind turbine 1 for storing backup energy to power the defrost assembly when not generating power. During operation, the power generation mechanism 101 inside the wind turbine 1 generates electricity under wind power. The defrost assembly, located at the bottom of the wind turbine 1, activates to heat the outer casing to prevent or defrost when the temperature is too low. The energy storage assembly, located on one side of the top of the wind turbine 1, stores backup energy for the defrost assembly when the wind turbine is not generating power, ensuring that the wind turbine can operate normally even in low-temperature environments, thus improving the reliability and efficiency of the equipment.
[0027] Furthermore, the defrosting assembly includes: a liquid storage chamber 3 located at the bottom of the wind turbine 1, the liquid storage chamber 3 being filled with water; multiple return pipes 303 located on the inner wall of the wind turbine 1, the return pipes 303 having a ring structure located inside the wind turbine 1, and both ends of the return pipes 303 being connected to the liquid storage chamber 3; and a heating pipe 301 located inside the liquid storage chamber 3.
[0028] During use, the water in the storage chamber 3 is heated by the heating pipe 301 and turns into water vapor. As it passes through the return pipe 303, the heat is transferred to the entire surface of the wind turbine 1, thereby thawing the outer shell. Using water for thawing also takes advantage of the higher specific heat capacity of water to prevent uneven heating of the wind turbine 1, which could lead to internal expansion and contraction stress and damage to the wind turbine 1. The annular return pipe 303 can evenly distribute heat, improve thawing efficiency, and reduce energy loss.
[0029] Furthermore, multiple guide fins 304 are provided on the inner walls of both sides of the reflux pipe 303. The multiple guide fins 304 are equidistantly distributed among each other. The multiple equidistantly distributed guide fins 304 increase the contact surface between the inner wall of the reflux pipe 303 and the water vapor, thereby promoting heat exchange, making heat transfer more efficient, and shortening the thawing time.
[0030] Furthermore, multiple guide rods 305 are provided on the inner wall of the top of the return pipe 303, and the bottom of each guide rod 305 is set in a semi-circular structure. During use, the semi-circular structure at the bottom of the guide rod 305 can help guide water vapor to flow downward along the guide rod 305 after it is concentrated and dissipated upwards, forming a cooling water return and improving the return speed of the coolant.
[0031] Furthermore, the heating tube 301 is equipped with a heating wire 302 inside, and the heating wire 302 is arranged in a serpentine structure. The heating tube 301 is made of thermally conductive ceramic material. During use, the serpentine heating wire 302 is embedded in the heating tube 301 made of thermally conductive ceramic material. After being energized, it generates heat and heats the water in the liquid storage chamber 3. The use of thermally conductive ceramic material can provide good heat conduction performance, while the serpentine structure of the heating wire ensures sufficient heating area and improves heating efficiency.
[0032] Example 2
[0033] Based on Embodiment 1, the energy storage component includes: a receiving slot 2 opened on one side of the top of the wind turbine 1, and a photovoltaic panel 201 disposed inside the receiving slot 2; a battery 202 disposed inside the wind turbine 1, a photovoltaic converter 204 disposed on one side of the battery 202, and the battery 202 is connected to the photovoltaic panel 201 through the photovoltaic converter 204.
[0034] During use, the photovoltaic panel 201 is installed in the receiving tank 2, absorbs solar energy and converts it into electrical energy, which is then stored in the battery 202 through the photovoltaic converter 204. By using clean energy as an auxiliary energy source, the dependence on external power sources is reduced, and the independence and environmental friendliness of the system are increased.
[0035] Furthermore, the photovoltaic panel 201 is designed with an arc-shaped inclined structure. During use, the arc-shaped inclined photovoltaic panel 201 can maximize the reception of sunlight, improve the photovoltaic power generation efficiency, and thus adapt to different angles of sunlight, increase the amount of sunlight collected, and improve energy collection efficiency.
[0036] Furthermore, the wind turbine 1 is equipped with a main control circuit board 203, which is electrically connected to the power generation mechanism 101, photovoltaic panel 201, battery 202 and heating wire 302, thereby realizing intelligent control of each part of the system, optimizing energy management and utilization efficiency, and ensuring the stable operation of the system.
