Automatic opening-closing platform cover plate device of wind generation set tower and system and control method of automatic opening-closing platform cover plate device

Abstract

The invention discloses an automatic opening-closing platform cover plate device of a wind generation set tower and a system and control method of an automatic opening-closing platform cover plate device, and belongs to the field of auxiliary equipment for a wind generation set. The automatic opening-closing 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 platform cover plate to be opened and closed; the monitoring device comprises a controller, a proximity sensor and a safety sensor, the proximity sensor and the safety sensor are connected with the controller, fixed to the inner wall of the tower and used for monitoring the running data of a climb-free device, the running data of the proximity sensor is used for judging whether to conduct the automatic opening or closing of the platform cover plate or not, the safety sensor is used for judging whether the climb-free device is within a safe range or not, the controller judges the running tendency of the climb-free device according to the running data of the climb-free device, and the controller controls the driving device to achieve the automatic opening or closing of the platform cover plate according to the judging result. By means of the automatic opening-closing platform cover plate device of the wind generation set tower, the body position of the climb-free device can be monitored and judged through the monitoring device, and the automatic opening or closing of the platform cover plate is controlled according to the judgment, so that 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.
