Automatic open-close platform cover plate device of wind turbine generator tower and system and control method thereof

Abstract

The invention discloses an automatic open-close platform cover plate device of wind turbine generator tower and a system and a control method thereof, which belongs to the field of generating set auxiliary equipment. The automatic open-close platform cover plate device comprises a platform cover plate, a driving device and a monitoring device, wherein the driving device is used for driving the open and close of the platform cover plate and comprises a driving motor, a driving shaft and a driving shaft sleeve matched with the driving shaft, the platform cover plate realizes open and close under the drive of the driving motor, the driving device also comprises a support plate for supporting the driving shaft and the platform cover plate, and a damping hinged plate is arranged at the connection site of the support plate and the platform cover plate; and the monitoring device comprises a controller and a proximity transducer connected with the controller, the proximity transducer is used for monitoring the running data of a climb free device, the controller is used for judging the running trend of the climb free device and controlling the automatic open and close of the platform cover plate according to the judgment results. The automatic open-close platform cover plate device disclosed by the invention monitors and judges the position of the climb free device through the monitoring device, and controls the automatic open and close of the platform cover plate according to the judgment, so as to reduce the personal safety risk.

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.
