Intelligent lifting tower of lifting offshore wind turbine

Abstract

The invention discloses an intelligent lifting tower of a lifting offshore wind turbine. The intelligent lifting tower comprises a plurality of sections of outer supporting towers, inner supporting towers, fixed edges, sliding column pieces, hydraulic abutting mechanisms, elastic damping mechanisms, sliding limiting cylinders, screw rod limiting mechanisms and atomization modules, and the outer supporting towers and the inner supporting towers are coaxially and slidably arranged at intervals; first limiting edges are arranged at the two ends of the inner circumferential face of the outer supporting towers respectively, second limiting edges are arranged at the two ends of the outer circumferential face of the inner supporting towers respectively, the first limiting edges and the second limiting edges are correspondingly connected in a clamped mode, the atomization modules are arranged on the fixed edges, and telescopic sealing cylinders are arranged at the two ends of the fixed edges correspondingly; and the sealing cylinders seal the sliding column pieces, oil cylinders are arranged on the atomization modules, the atomization modules spray oil in the oil cylinders into the sealingcylinders, lubricating oil can be sprayed through the atomization modules, and therefore the sealing cylinders can be lubricated, the maintenance efficiency is greatly improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy equipment, in particular to an intelligent lifting tower for a lifting offshore wind power generator. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. In a broad sense, wind energy is also solar energy, so it can also be said that a wind generator is a thermal energy utilization generator that uses the sun as a heat source and the atmosphere as a working medium. The traditional wind turbine does not have a lifting adjustment mechanism, which is not convenient for maintenance when the wind turbine fails, and it is impossible to adjust it when there is a typhoon or other destructive weather, so as to disassemble it and make the wind power Generators are easily damaged. [0003] Chinese patent CN201620785662.9 discloses a lifting and rotating mechanism of a win...

AI Technical Summary

Problems solved by technology

[0004] The wind turbine is a large-scale equipment, and the lifting structure of the device is not stable enough only through the meshing transmission, which may cause the risk of the fan falling;

[0005] Most of the lift towers are in the stretched state during the power generation process, so it needs to go through long-term sea wind erosion, which will have a certain impact on the service life of the lift tower. At the same time, during the maintenance of the lift tower, due to Regular maintenance needs to be carried out at its lifting position. During the maintenance process, it needs to be maintained by manual climbing, which causes the problem of high maintenance costs.
