[0002] A wind turbine tower, commonly known as a wind turbine tower or wind turbine tower, is a large structure primarily used to support wind turbines. Its primary function is to mount the wind turbine at an appropriate height to capture more wind energy at high altitudes and convert it into electricity. However, wind power generation can be affected by external factors, which can reduce power generation. In winter, rainwater can easily form ice on the blades and tower, increasing the weight of the blades, slowing their rotation, reducing power generation, and increasing blade maintenance costs. Furthermore, wind turbine towers are subject to vibration during use due to natural factors, which can reduce the stability of the entire tower. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a wind power generation tower with an anti-icing protection structure which is not easy to be iced, has strong stability, is easy to maintain and is economical and practical.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0019] like Figures 1 to 4 As shown, the wind power generation tower with an anti-icing protection structure of the present invention includes a wind power generation tower, which is mainly composed of a mounting base 1, a bracket 9, a main control box 8 and blades 4. The rotation of the blades can convert wind energy into electrical energy for power supply operations.

[0020] The outer surface of the master control box and the blade is provided with a super-hydrophobic layer 14, which can effectively protect the blade in the cold winter, from the ice produced by the freezing of rainwater, and the normal operation of the wind power generation is guaranteed, the number of maintenance times is reduced, and the power generation in winter is improved. Moreover, the super-hydrophobic coating has the properties of corrosion resistance, self-cleaning, anti-fog, drag reduction, anti-icing, and can meet the requirements of different application fields. In addition, the super-hydrophobic coating is also transparent, UV-resistant, anti-reflective, water-resistant, heat-insulating, flame-retardant and other properties, which can further expand the scope of application. For example, the JN-SS002&JN-SS003 super-hydrophobic and super-oleophobic nano coating (normal temperature self-drying type) of Zhongke Jingna is a revolutionary waterproof material, which is completely isolated from the immersion of water and oil using the latest nano hybrid technology. It is a hydrophobic and oleophobic coating with protection against almost all liquid damage, and nano-modification technology is used to form a layer on the surface of the substrate that can stop the air protection film of liquid erosion such as water and oil. This protective film is superior to traditional technologies, has super strong adhesion and wear resistance, and can also be used in places where there are certain requirements for wear resistance. It is designed to solve problems such as waterproofing and dustproofing of surfaces of objects related to industrial users and ordinary users.

[0021] A protective coating is provided on the outer surface of the bracket, and the protective coating comprises, from the inside to the outside, an epoxy zinc-rich primer layer 24, an epoxy micaceous iron intermediate paint layer 23 and a fluorocarbon topcoat layer 22; the protective coating can overcome the technical difficulties of the hydrophilic galvanized surface of the power tower and the easy freezing at low temperatures, so that the power tower body can achieve the three-proof purpose (anti-corrosion, anti-fouling, anti-freezing), extend the service life, and be economical and practical.

[0022] The mounting base and the bracket are provided with a stabilizing mechanism, which is mainly composed of a sliding block 3, a fixing seat and a connecting rod.

[0023] in,

[0024] The sliding block is annular and is movably mounted on the bracket; four first rotating shafts 10 are evenly arranged on the outer circumference of the sliding block, and four fixed seats 13 are matched on the mounting base, each fixed seat has a second rotating shaft 12, and each corresponding sliding block and fixed seat are connected by a connecting rod 11, and the two ends of the connecting rod are respectively rotatably connected to the first rotating shaft on the sliding block and the second rotating shaft on the fixed seat.

[0025] The fixing seat is set on the mounting base; a sliding groove 15 is opened inside the fixing seat, and a sliding rod 16 is set through the inside of the sliding groove, and a slider 17 is slidably connected to the sliding rod; a first spring 18 is sleeved on the sliding rod, one end of the first spring is fixedly connected to one end of the sliding groove and the other end is fixedly connected to the slider; a second rotating shaft is fixedly set on the upper end of the slider.

[0026] The bracket is fixedly mounted in the middle of the mounting base, which is threaded with positioning bolts 2 to stabilize the entire wind turbine tower. The upper end of the bracket is fixedly connected to the main control box, and the blades are mounted at one end of the main control box. The upper end of the main control box is connected to the buffer plate 6 via several fixing blocks 5. The fixing blocks have a limit slot 21 defined within them, into which a movable frame 7 is movably connected. The limit slot is fixedly connected to one end of a second spring 20, the other end of which is fixedly connected to the limit plate 19. The inner end of the movable frame is fixedly connected to the limit plate, and the outer end of the movable frame is fixedly connected to the buffer plate.

[0027] Working Principle: First, the entire wind turbine is installed in the appropriate position using the positioning bolts on the mounting base, and the entire wind turbine is connected to the outside world for power operation. During use, the wind turbine will be shaken by natural factors. At this time, under the action of the first and second rotating shafts, the bracket can drive the connecting rod to move outward. The connecting rod can drive the slider to squeeze the first spring. Under the action of the first spring, a buffering effect can be achieved, which can reduce the vibration force on the entire wind turbine, thereby improving the stability of the entire wind turbine and increasing its service life. The surface of the blades and the main control box are coated with a super-hydrophobic layer to effectively protect the blades from ice formed after rain freezing in the cold winter, ensuring the normal operation of wind power generation, reducing the number of maintenance times, and increasing winter power generation.

[0028] In extreme weather, such as hail, falling hail can cause damage to the control box. The buffer plate design can improve the protection of the control box. Because the hail first contacts the control box, the pressure on the buffer plate drives the movable frame and the limit plate to compress the second spring to achieve a buffering protection function.
