technical field

The invention relates to a maintenance and construction device for the outer wall of a wind power generator tower, in particular to an equipment assembly used for maintenance and construction of the outer wall of a wind power tower such as cleaning, repair, painting, and replacement of parts.

Background technique

Wind power is an important renewable and clean energy. The development of wind power is of great significance to reduce the dependence on traditional petrochemical energy, optimize the energy structure, and realize the sustainable development of society. Therefore, vigorously developing wind power has become a new energy development field in many countries. important measures. my country has also achieved rapid development in the field of wind power generation. As of the end of 2014, the total installed capacity of wind power generation in my country was close to 100 million kilowatts, and the installed capacity exceeded 100,000 units. It will maintain a high-speed development trend for a long time in the future.

A wind turbine consists of a tower fixed on the ground to support components such as the wind rotor, the nacelle, and the generator set. In order to obtain better quality and more wind resources, towers often need to be tens of meters high, or even hundreds of meters high.

The tower tube is exposed to the natural environment for a long time, and is subject to wind, sun, rain, and even salt spray and sand dust, which can easily lead to coating damage, paint peeling, and corrosion on the outer wall of the steel tower tube; at the same time, the tower tube The fasteners at the segmental connection parts also have a certain service life, and they are repaired and replaced after a certain period of use; after some wind turbines have been running for a period of time, lubricating grease leaks from the nacelle on the tower, combined with dust and other sundries. A layer of dirt is formed on the outer wall of the tower, which will not only affect the appearance of the fan, but also affect the safety of the fan. Therefore, it is necessary to regularly carry out maintenance measures such as rust removal, paint repair, painting repair, replacement of parts, and cleaning on the outer wall of the tower to improve the appearance of the fan, prolong the service life of the tower, and ensure the safe operation of the fan.

At present, the maintenance and maintenance of domestic wind power towers is relatively common. The construction personnel must first climb to the top of the tower, and then tie the construction personnel through the ropes fixed on the nacelle, and then gradually lower them, and hang the construction personnel near the tower. The construction is carried out in the air; or the cage is lifted by a large crane, and the construction personnel operate in the cage. The height of the wind power tower ranges from tens of meters to more than 100 meters. In addition, the wind speed at the location where the wind turbine is built is high, which not only has great requirements on the physical and psychological quality of the construction workers, but also has high labor intensity and low work efficiency. Moreover, The construction in the cage lifted by the crane has strict requirements on the external environment such as the work site and wind speed, long preparation time and high cost. Therefore, every maintenance and maintenance of the wind power tower will consume a lot of manpower and material resources.

With the rapid increase in the number of installed wind power in my country, and the wind turbines built before are gradually entering the maintenance period, there is an increasing market demand for the maintenance, cleaning, overhaul, and replacement of parts of wind power towers, while traditional maintenance The operation method is gradually difficult to meet the rapidly growing market demand. Therefore, the development of a wind turbine tower outer wall maintenance system with high construction efficiency, high safety and reliability, and greatly improved operator comfort is of great importance to the development of wind power in my country. significance.
