Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine tower rainproof devices, in particular to a rainproof cover for hoisting a wind turbine tower. Background Art

[0002] There are two main types of devices for protecting wind turbine towers from rain: a hard rain cover and a soft rain cover. Hard rain covers are mainly used for long-term rain protection scenarios, such as after the first or first two sections of the wind turbine tower are pre-hoisted, or after the offshore wind power tower is pre-assembled on land, the open tower top is protected from rain for a long time, which lasts for about 7 to 90 days; soft rain covers are mainly used for rain and dust protection during horizontal long-distance transportation after the tower is manufactured, and the sealing and fastening mainly rely on the use of vehicle sealing tape at the end of the tower; while for the hoisting of wind turbine towers in the rainy season, the protection time is about 30 minutes to 2 hours, which is less studied. The hard rain cover is large in size, heavy in weight, and has a large windward area. The probability of wind and rain coming at the same time is very high, and large crane resources need to be occupied during the hoisting process, which has a great impact on construction efficiency and has strict requirements on wind speed during implementation; the soft rain cover cannot be sealed in the air because it is at high altitude, and the expected effect of wind and rain protection cannot be achieved. Therefore, the current wind turbine tower installation rain cover mainly adopts the hard rain cover solution;

[0003] In wind power generation project construction, when the tower top is still exposed during tower installation or before the nacelle is installed, sudden rain, or even rain almost every day during the rainy season, can have a significant impact on wind turbine installation. To quickly address the impact of rain on installation and ensure the quality of finished wind turbine equipment, it is necessary to complete the finished equipment protection work within a limited time. Existing rigid rain covers require large cranes for installation, which occupies large equipment resources, is inconvenient to install, and the entire rain protection installation process is relatively slow.

[0004] When existing wind turbine hoisting towers need to be protected from rain on rainy days, they cannot be easily installed and quickly deployed to achieve rain protection. Therefore, this application proposes a rain cover for wind turbine tower hoisting. Utility Model Content

The use of the rain cover 3 does not require the use of a large crane for hoisting, and does not occupy large equipment resources; it is easy to install and has a fast response time, and can be used in sudden rainy days; the rain cover 3 covering the wind turbine hoisting tower A is provided with an integrally sewn limiting sleeve 33, and a high-strength magnetic strip 32 is sewn on the round edge of the rain cover 3. When the rain cover 3 is unfolded, the high-strength magnetic strip 32 is firmly adsorbed to the magnetic steel plate ring a2 on the wind turbine hoisting tower A. A sealing effect of the rain cover 3 is achieved; a split rainwater collector 4 is provided with a pressure plate 41 and a water guide pipe 42 on the outer surface of the rainwater collector 4. The rainwater collector 4 has its own weight. The rainwater collector 4 is placed in the limiting sleeve 33. The rainwater collector 4 presses the limiting sleeve 33 and is installed inside the bolt hole a1 of the wind turbine hoisting tower A. The size of the rainwater collector 4 is consistent with the aperture of the bolt hole a1. Under the dead weight of the rainwater collector 4, the effect of fixing the unfolded rain cover 3 is achieved. In addition, the number of rainwater collectors 4 can be adjusted according to actual needs. By increasing the number of rainwater collectors 4, the rainwater collector 4 can be placed in the limiting sleeve 33. The number of collectors 4 increases the weight of the rain cover 3, so that the rain cover 3 is light in weight without reducing the rain and wind protection effect; the lifting component installed on the support frame 11 includes an adjusting screw 22 that passes through the center of the support frame 11 and a lifting shell 21 connected to the top of the adjusting screw 22. The adjusting screw 22 is supported by the support frame 11, and the lifting shell 21 can lift the center position of the rain cover 3 to form a conical shape with a high center protrusion and a low round edge, which is conducive to the rainwater on the rain cover 3 to flow to the side, and avoids the accumulation of rainwater on the rain cover 3 and causing depression.

[0026] In this embodiment, the support frame 11 is a "+"-shaped structure. A first screw hole is provided at the center of the support frame 11. A bolt fixed to the wind turbine hoisting tower A is provided at the end of the support frame 11 away from the first screw hole. The support frame 11 is fixedly installed and supports the unfolded rain cover 3.

[0027] In this embodiment, the lifting shell 21 includes an inwardly concave hemispherical shell and a sealing bottom plate. The top end of the adjusting screw 22 is connected to the center position of the sealing bottom plate. The adjusting screw 22 cooperates with the first screw hole. The adjusting screw 22 is screwed together with the support frame 11 through a threaded connection. The height position of the lifting shell 21 can be adjusted, thereby changing the slope of the protrusion at the center position of the rain cover 3.

[0028] In this embodiment, the wind turbine hoisting tower A is provided with a bolt hole a1 and a magnetic steel plate ring a2. The high-strength magnetic strip 32 is connected to the steel plate ring a2 by magnetic adsorption. The high-strength magnetic strip 32 is firmly connected to the steel plate ring a2 to prevent the rain cover 3 from fluttering.

The water pipe 42 is in an inclined state. The angle between the water pipe 42 and the outer surface of the rainwater collector 4 is angle b. The size of angle b can be adjusted according to actual conditions to achieve the effect of rainwater accumulated in the rainwater collector 4 falling to the outside of the wind turbine hoisting tower A. The rainwater collector 4 can collect rainwater that falls on the surface of the rainproof cover 3. The accumulation of rainwater in the rainwater collector 4 can increase the weight of the rainwater collector 4, thereby increasing the deadweight of the rainproof cover 3. In addition, more rainwater in the rainwater collector 4 can flow out from the water pipe 42 and fall to the outside of the wind turbine hoisting tower A.

[0031] The working principle and use process of this utility model:

[0034] The fixing rope 12 can further tighten the rain cover 3;

[0035] The high-strength magnetic strip 32 is connected to the steel plate ring a2 by magnetic adsorption. The high-strength magnetic strip 32 is firmly connected to the steel plate ring a2 to prevent the rain cover 3 from floating;

[0036] The rain cover 3 is made of a lightweight rainproof plastic fabric. The rain cover 3 is light and relatively soft, and can be folded into a small volume and stored, or placed in the inner passage of the wind turbine hoisting tower A for easy carrying. The use of the rain cover 3 does not require the use of a large crane for hoisting, and does not occupy large equipment resources; it is easy to install, has a fast response time, and can be used in sudden rainy days;

[0037] The adjusting screw 22 is screwed to the support frame 11 to adjust the height of the lifting shell 21, thereby changing the slope of the bulge at the center of the rain cover 3, so that rainwater falling on the surface of the rain cover 3 flows from a high position to a low position;

[0038] The rainwater collector 4 is placed in the limiting sleeve 33, and the rainwater collector 4 presses the limiting sleeve 33 and is installed inside the bolt hole a1 of the wind turbine hoisting tower A. Under the weight of the rainwater collector 4, the expanded rain cover 3 is fixed. By increasing the number of rainwater collectors 4 and increasing the weight of the rain cover 3, the rain cover 3 is made light while maintaining the rain and wind protection effect.

[0039] To sum up: the rainproof device of the present application can be easily installed and quickly deployed to achieve the purpose of rain protection and shielding. The support frame 11 supports the deployed rain cover 3. The rain cover 3 is firmly connected to the steel plate ring a2 on the wind turbine hoisting tower A through magnetic adsorption.
