Automatic opening and closing platform cover device, system and control method of wind turbine tower

Abstract

The invention discloses an automatic platform cover plate opening and closing device of a wind turbine generator tower frame, a system and a method, and belongs to the field of auxiliary equipment of wind turbine generators. The automatic platform cover plate opening and closing device comprises a platform cover plate, a drive device and a monitor device. The drive device is used for driving the platform cover plate to be opened and closed. The monitor device comprises a controller and proximity detectors connected with the controller. The proximity detectors are fixed to the inner wall of the tower frame and used for monitoring operating tendency data of a climbing-free device. The controller is used for judging the operating tendency of the climbing-free device according to the monitored operating data of the climbing-free device and used for controlling the drive device to achieve automatic opening and closing of the platform cover plate according to the judgment result. According to the automatic platform cover plate opening and closing device of the wind turbine generator tower frame, the system and the method, the car body position of the climbing-free device can be monitored and judged through the monitor device, automatic opening and closing of the platform cover plate are controlled according to judgment, and the personal safety risk is reduced.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for wind power generating sets, in particular to an automatic opening and closing platform cover device, system and control method for a tower of a wind power generating set. Background technique [0002] With a large number of wind turbines connected to the grid for power generation, the on-site operation and maintenance workload of wind turbines has increased significantly. Because the tower height of megawatt-scale wind turbines is generally very high, operation and maintenance personnel must spend a lot of physical strength climbing the tower to enter the nacelle to carry out maintenance work. Therefore, currently wind turbines mostly use climbing devices to help operation and maintenance personnel save climbing Physical expenditure of the tower. [0003] The free climber is a motor-driven lifting device (including car body, driving device and control device). The operation and maintenance ...

Problems solved by technology

Although the non-climbing device will automatically slow down when it approaches the protective cover and remind the operation and maintenance personnel to pay attention, on the one hand, due to the large length of the protective cover, it is inconvenient to operate; on the other hand, the operation and maintenance personnel need both hands to control the switch of the non-climbing device. Make it run, and the protective cover cannot be fully opened at the position before the person rushes to the top. If the body of the climbing avoidance device is not stopped in time, it will cause a collision accident between the person and the protective cover.
