[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a wind power sealing brush that is easy to replace, comprising a connecting base 1, wherein an assembly groove 11 is provided on one outer wall and the front side of the connecting base 1, and an assembly part 12 is provided on the other outer wall and the back side of the connecting base 1, the assembly part 12 being positioned corresponding to the assembly groove 11, a second hole 13 being provided through the interior of the assembly part 12, and a first hole 10 being provided on the top of the connecting base 1, the first hole 10 being located above the assembly groove 11;

[0024] Two sets of mounting slots 11 are provided on the front of the connecting base 1, and two sets of mounting slots 11 are also provided on one side of the connecting base 1. According to the actual size of the wind turbine, several connecting bases 1 are assembled together in sequence and direction. Then, the complete sealing brush is fixed in the corresponding position inside the wind turbine, that is, the fitting 12 on one side of one set of connecting base 1 is embedded into the mounting slot 11 on the outer wall of another set. Then, the bolt is inserted into the corresponding hole 10, and the bolt also passes through the fitting 12 on the hole 23 to fix the two adjacent sets of connecting bases 1. If a wider brush is required, the back of one set of connecting base 1 is placed on the side. The fitting 12 on one side is assembled into the mounting groove 11 on the back of another set of connecting bases 1. At the same time, bolts are inserted into holes 10 and 13 to fix the two sets of connecting bases 1. The brush is designed in a segmented manner, and this fixing method facilitates the installation, disassembly and transportation of the brush. After installation, the connecting bases 1 are tightly connected into a whole by fitting the fitting 12 into the mounting groove 11 and fixing it with bolts. This improves the flexibility of the brush and also improves the overall sealing of the brush to a certain extent. The connecting base 1 is made of aluminum alloy, which makes the connecting base 1 lightweight, high-strength and corrosion-resistant.

[0025] The connecting base 1 has an installation groove 17 inside. The top wall of the installation groove 17 is provided with a connecting magnetic strip 2 4. The installation groove 17 is provided with a fixed brush plate 2 and a connecting magnetic strip 3. The connecting magnetic strip 3 is located between the fixed brush plate 2 and the connecting magnetic strip 2 4. The bottom of the fixed brush plate 2 is provided with brush strips 7 in an alternating manner.

[0026] The front and back of the connecting base 1 are provided with fixing bolts 2 and 9, which are used to fix the connecting base 1 and the fixing brush plate 2.

[0027] The connecting base 1 has a fixing hole 14 on both the front and back sides, and the fixing hole 14 is used to place the fixing bolt 9.

[0028] The fixed brush plate 2 has a fixing hole 3 16 on both the front and back sides, and the fixing hole 3 16 corresponds to the fixing hole 14.

[0029] The connecting base 1 has an internal mounting groove 17, which is U-shaped to facilitate the insertion of the fixing brush plate 2 into the mounting groove 17. A connecting magnetic strip 2 4 is fixed to the top wall of the mounting groove 17, and a connecting magnetic strip 3 is fixed to the top of the fixing brush plate 2. During installation, the fixing brush plate 2 is inserted into the mounting groove 17, and the connecting magnetic strip 3 and the connecting magnetic strip 4 will generate mutual attraction, making the connecting base 1 and the fixing brush plate 2 firmly attached together. Then, the fixing bolt 2 9 is screwed into the mounting bolts located on the front and back of the connecting base 1. The fixing hole 14 is opened, and the fixing bolt 2 9 passes through the fixing hole 14 and enters the fixing hole 3 16 to enhance the firmness of the installation between the fixing brush plate 2 and the connecting base 1, and facilitate the disassembly and replacement of the connecting base 1 and the fixing brush plate 2. The fixing brush plate 2 is made of plastic material, and the brush strip 7 is made of nylon material. It has the advantages of good wear resistance, strong chemical corrosion resistance and good flexibility. It can adapt to the complex environment in which the wind power equipment is located, such as wind, sand, rain and snow, and effectively prevent dust, impurities and rainwater from entering the wind turbine.

[0030] The top of the connecting base 1 is provided with a limiting strip 5, and an installation block 6 is sleeved on the outside of the limiting strip 5. Fixing bolts 8 are evenly arranged on the front and back of the installation block 6. The fixing bolts 8 are used to fix the limiting strip 5 and the installation block 6.

[0031] The limiting strip 5 has fixing holes 15 on both the front and back sides, and the fixing holes 15 correspond to the positions of the fixing bolts 8.

[0032] After fixing the fixed brush plate 2 inside the connecting base 1 and connecting each section of the connecting base 1, the connecting base 1 can be installed into the wind turbine. The limiting strip 5 on the brush is inserted into the mounting block 6 inside the wind turbine. Then, the fixing bolt 8 is inserted into the screw hole and fixing hole 15 of the mounting block 6 at the same time and tightened. The installation of the sealing brush is then completed.

[0033] Working principle: When installing the sealing brush, according to the actual gap between the nacelle and the tower, first insert the fixed brush plate 2 into the mounting groove 17, then screw the second fixing bolt 9 into the fixing holes 14 on the front and back of the connecting base 1 to fix the connecting base 1 and the fixed brush plate 2. Then, connect the multiple connecting bases 1 one by one in sequence and direction. Insert the fittings 12 on one set into the corresponding mounting grooves 11 on the other set of connecting bases 1, and tighten them with bolts inserted into holes 10 and 13 to tightly connect the connecting bases 1 into a whole. Then, insert the limiting strip 5 on the brush into the mounting clip 6 inside the wind turbine and fix it with the first fixing bolt 8. This makes the connecting base 1 firmly installed inside the wind turbine, which can effectively fill the gap between the nacelle and the tower, prevent external pollutants such as sand and rainwater from entering the nacelle, and protect the normal operation of the internal equipment.
