Description

Technical Field

[0001] The invention relates to the field of rainproof covers, in particular to a rainproof cover for installing a wind tower. Background Art

[0002] Wind power generation is the process of converting the kinetic energy of wind into mechanical energy, and then converting the mechanical energy into electrical energy. The wind power is used to drive the windmill blades to rotate, and the speed of rotation is increased through a speed increaser to drive the generator to generate electricity. The device required for wind power generation is called a wind turbine. This type of wind turbine can be roughly divided into three parts: the wind rotor (including the tail rudder), the generator and the tower.

[0003] At present, wind turbines are getting bigger and bigger, and their internal components are also getting bigger. When the bottom section of the wind tower is installed vertically, it is necessary to ensure that the inverter and other electrical equipment in the tower are not affected by moisture. However, during the installation of the vertical internal parts of the tower, bad weather will inevitably affect the tower. If rain protection is not done well, it will easily cause the inverter and other electrical equipment in the tower to get damp, resulting in component damage, delays in construction, and huge losses.

[0004] The existing method is generally to set a rain cover on the top, but there is a manhole cover on the top of the existing rain cover, which is used to flip over to provide space for operators to enter and exit. The gaps in this structure are easy for moisture to penetrate into the inside, causing the internal structure to be damaged by moisture. Therefore, it is necessary to design a rain cover for wind tower installation. Summary of the invention

[0005] The purpose of the present invention is to provide a rain cover for installing a wind tower, so as to solve the problem of water penetration in the manhole cover on the top of the existing rain cover.

[0007] Preferably, a limiting frame is integrally formed on the lower surface of the top sealing cover, and a limiting plate is fixed on the lower surface of the top sealing cover outside the limiting frame.

[0008] Preferably, the limiting plate and the limiting frame are separated by a groove which fits with the climbing inner well, and the number of the limiting frames is consistent with the number of the outer edges of the climbing inner well. The top sealing cover is fitted with the climbing inner well through the limiting plate and the limiting frame, so that the moisture entering the cavity is blocked by the limiting plate, and the water accumulated in the cavity will be discharged from the drainage hole, effectively preventing moisture penetration.

[0009] Preferably, an inner handle is provided at the center of the lower surface of the top sealing cover, and a counterweight is fixed to the outer side of the inner handle via a connecting rope.

[0010] Preferably, the diameter length of the top sealing cover is not less than the diameter length of the outer edge of the wind shield.

[0011] Preferably, a supporting frame is fixedly mounted on the lower surface of the rain cover.

[0012] Preferably, a sealing ring is welded to the outer end of the support frame, and a limiting ring is integrally formed at the bottom of the sealing ring.

[0013] Preferably, a convex ring is fixed to the lower surface of the rain cover, and the flange hole passes through the convex ring and the limiting ring.

[0014] Preferably, the middle part of the sealing ring has a group of recessed sections, and the recessed sections are annular recessed structures. The convex ring is inserted into the interior of the recessed sections, and the convex ring squeezes the recessed sections so that the outer edge of the recessed sections squeezes the upper edge of the inner wall of the tower body, thereby forming a sealing effect and enhancing the sealing at the connection.

[0015] Preferably, the sealing ring and the rain cover are separated by a cavity opening facing outward, and a plurality of sealing gaskets are arranged inside the cavity opening, wherein at least one sealing gasket is arranged at the outer edge of the cavity opening between the sealing ring and the rain cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The top sealing cover and the matching auxiliary structure provide a sealing structure that replaces hinged flipping with snap-fitting, which can be easily disassembled. While ensuring easy disassembly, it has strong sealing performance to ensure that rainwater does not penetrate into the interior. It can play a good moisture-proof role when used on rainy days, and has better sealing performance;

[0018] In addition, a sealing structure is provided at the connection between the rain shield and the tower body through the setting of a sealing ring and a matching auxiliary structure, which greatly strengthens the sealing connection between the rain shield and the tower body and effectively avoids the problem of moisture penetrating into the tower at the connection between the rain shield and the tower body.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 A rain shield for installing a wind tower, comprising a rain shield 10, a surface of the rain shield 10 is provided with a plurality of flange holes 11 penetrating therethrough, a top surface of the rain shield 10 is provided with a plurality of wind shields 12, a climbing inner well 121 is provided on the inner side of the wind shield 12, the wind shield 12 is a cylindrical structure, the climbing inner well 121 is a polygonal plate structure, a top sealing cover 14 for sealing the climbing inner well 121 is engaged on the top surface of the wind shield 12, a plurality of cavities are separated between the wind shield 12 and the climbing inner well 121, a plurality of drainage holes 122 are provided on the outer surface of the wind shield 12, and the drainage holes 122 are all connected to the cavities;

[0028] By setting a top sealing cover 14 that is installed by snapping, a structure that can seal the climbing inner well 121 is provided. The outside of the top sealing cover 14 is used to keep out rain, and the water that penetrates into the interior will be discharged along the drainage hole 122, effectively ensuring the drainage effect and preventing moisture from penetrating into the interior and causing the problem of electronic components getting damp.

[0029] Among them, a limiting frame 141 is integrally formed on the lower surface of the top sealing cover 14, and a limiting plate 142 is fixed to the lower surface of the top sealing cover 14 on the outside of the limiting frame 141. A groove fitting with the climbing inner well 121 is separated from the limiting plate 142 and the limiting frame 141. The number of limiting frames 141 is consistent with the number of the outer edges of the climbing inner well 121. The top sealing cover 14 is fitted with the climbing inner well 121 through the limiting plate 142 and the limiting frame 141, so that the moisture entering the cavity is blocked by the limiting plate 142, and the water accumulated in the cavity will be discharged from the drainage hole 122, effectively preventing moisture penetration.

[0030] Among them, an inner handle 143 is set at the center position of the lower surface of the top sealing cover 14, and a counterweight 144 is fixed to the outer side of the inner handle 143 through a connecting rope. The opening is made by pushing the inner handle 143 upward, and the counterweight 144 ensures that the limit frame 141 and the limit plate 142 are stably engaged with the climbing inner well 121 in the case of vibration.

[0031] Among them, the diameter length of the top sealing cover 14 is not less than the diameter length of the outer edge of the wind shield 12. This setting is to ensure that the top sealing cover 14 can always cover the upper surface of the climbing inner well 121 to ensure that water will not enter the climbing inner well 121.

[0032] A support frame 13 is fixedly mounted on the lower surface of the rain cover 10 , and an internal support effect is formed by the support frame 13 . The support frame 13 is generally fixed to the rain cover 10 by welding.

[0033] Among them, a sealing ring 131 is welded to the outer end of the supporting frame 13, and a limiting ring 132 is integrally formed at the bottom of the sealing ring 131. The sealing ring 131 is used to seal the connection between the rain cover 10 and the tower body. The limiting ring 132 can not only provide position restriction for the structure, but also provide a concave notch, which can effectively prevent water from penetrating into the interior.

[0034] Among them, a convex ring 15 is fixed on the lower surface of the rain cover 10, and the flange hole 11 passes through the convex ring 15 and the limiting ring 132. The convex ring 15 is used to provide extrusion for the sealing ring 131, so that the middle part of the sealing ring 131 is close to the upper edge of the inner wall of the tower body, further strengthening the sealing of the connection.

[0035] Among them, the middle part of the sealing ring 131 has a group of recessed sections 134, and the recessed sections 134 are annular recessed structures. The convex ring 15 is inserted into the interior of the recessed sections 134, and the convex ring 15 squeezes the recessed sections 134 so that the outer edge of the recessed sections 134 squeezes the upper edge of the inner wall of the tower body, thereby forming a sealing effect and strengthening the sealing at the connection.

[0036] Among them, the sealing ring 131 and the rain cover 10 are separated by a cavity facing outward, and a plurality of sealing gaskets 133 are arranged inside the cavity, wherein at least one sealing gasket 133 is arranged at the outer edge position of the cavity between the sealing ring 131 and the rain cover 10, which can ensure that during the installation process, the recessed section 134 is squeezed, causing the sealing ring 131 to deform, and providing a deformation space for the sealing ring 131 through the cavity, and then cooperating with the sealing gasket 133 to provide a gap position after deformation for sealing, thereby enhancing the sealing effect and ensuring that the deformation will not cause gaps on the surface, thereby causing water leakage.

[0037] Working principle: When in use, the rain cover 10 is installed through the flange hole 11, and the connection is sealed. In daily use, the top sealing cover 14 is used to provide waterproofing at the top. Part of the water source will enter the cavity from the gap between the top sealing cover 14 and the wind shield 12. The water source entering the interior will be blocked by the limit plate 142. The blocked water source will flow between the wind shield 12 and the climbing inner well 121, and then be discharged from the drainage hole 122. When the operator wants to open the top sealing cover 14, he only needs to push it upward from the inside or pull it out from the top to disassemble it. In daily use, the counterweight 144 will provide a downward pressure effect at the connection to ensure the tightness of the connection between the top sealing cover 14 and the climbing inner well 121.

[0038] During the installation process, the rain cover 10 on the top will first squeeze the recessed section 134 inward, and the squeezed recessed section 134 will produce a certain deformation, and the deformation will be transmitted to the end of the sealing ring 131. Since the end is fixed to the rain cover 10 by bolts, the sealing gasket 133 arranged between the end of the sealing ring 131 and the rain cover 10 will be squeezed, so that the gap caused by the deformation is blocked by the sealing gasket 133 to ensure the sealing. When the recessed section 134 is deformed, it will fit tightly to the upper edge position of the inner wall of the tower body to ensure the internal sealing. In addition, during installation, an annular groove that cooperates with the limit ring 132 is required to be provided on the upper surface of the tower body, and a limiting connection is made with the limit ring 132 through the annular groove, which is convenient for installation and can enhance the sealing effect. The structure is simple and the operation is convenient.
