Problems solved by technology

[0002] At present, domestic and foreign are vigorously developing and constructing green wind power generation projects. However, due to special reasons, the installation projects of wind turbines (including installation projects of offshore and onshore wind turbines) need to be shut down for a long time after hoisting and erecting two towers. For a period of time, during the period of suspension of hoisting, the two towers that have been hoisted and erected are prone to be eroded by rainwater, dust and other substances to the inside of the tower due to their exposed tops, resulting in damage to the equipment and components inside the tower. Rust corrosion and damage, resulting in certain property and economic losses

Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific examples.

[0027] The top protection structure provided by this embodiment after the wind power tower is hoisted and erected in two sections can be effectively used in offshore wind power installation projects and land installation wind power projects in the top protection protection after the wind turbine tower is hoisted and erected in two sections, and is suitable for 1.5MW-6.0MW and other offshore and onshore high-power wind turbines (with different tower diameters) are used for top protection after hoisting and erecting two tower sections. Such as Figure 1 to Figure 6 As shown, the top protective structure includes three parts: a rainproof tarpaulin cover 1, a stainless steel awning ring rainproof tarpaulin 2, and a stretched rubber rainproof tarpaulin 3. Wherein, the rainproof tarpaulin cover 1 is made of polyvinyl chloride plastic-coated canvas with a thickness of 1-2mm and a di...

Abstract

The invention discloses a top protection structure applied to wind power tower drums after hoisting two vertical sections and a paving method thereof. The top protection structure comprises a rainproof tarpaulin hood, a stainless steel awning ring rainproof tarpaulin and a tensile rubber rainproof tarpaulin, wherein the rainproof tarpaulin hood is a circular hood with shape and size which are matched with that of the top of a second tower drum section; the stainless steel awning ring rainproof tarpaulin is sewed on the inner layer of the rainproof tarpaulin hood; a plurality of stainless steelawning rings are embedded at the edge of the stainless steel awning ring rainproof tarpaulin; one end of a hemp rope is fixedly fastened in one hole of each of the plurality of stainless steel awningrings; the tensile rubber rainproof tarpaulin is vertically sewed on the circumference edge of the rainproof tarpaulin hood to form a straight drum shape; tensile rubber bands are sewed on the innerlayer of the tensile rubber rainproof tarpaulin; through the sewed tensile rubber bands, the tensile rubber rainproof tarpaulin is clung to the surface of the circular outer wall of the top of the second tower drum section during paving. The top protection structure has operability and practical significance to the protection problems such as rainwater resistance, sand and dust resistance and corrosion resistance and the like of wind power plants after hoisting two vertical tower drum sections.

Description

technical field [0001] The invention relates to the technical field of wind power tower protection, in particular to a top protection structure and a laying method of a wind power tower after hoisting and erecting two sections. Background technique [0002] At present, domestic and foreign are vigorously developing and constructing green wind power generation projects. However, due to special reasons, the installation projects of wind turbines (including installation projects of offshore and onshore wind turbines) need to be shut down for a long time after hoisting and erecting two towers. For a period of time, during the period of suspension of hoisting, the two towers that have been hoisted and erected are prone to be eroded by rainwater, dust and other substances to the inside of the tower due to their exposed tops, resulting in damage to the equipment and components inside the tower. Rust corrosion and damage, resulting in certain property and economic losses. In order ...
