Alarm system for bolt looseness of wind turbine tower

Abstract

The invention provides an alarm system for bolt looseness of a wind turbine tower. The alarm system comprises a monitoring assembly directly facing the wind turbine tower and a monitoring host arranged in the wind turbine tower, and the monitoring host is in communication connection with the monitoring assembly; the monitoring assembly comprises an air speed and air volume sensor and a plurality of groups of video acquisition modules; a data integration module, a model establishment module, a data comparison module and an alarm module are arranged in the monitoring host; the data integration module is used for recording first data information; the model establishment module is used for recording second data information; the data comparison module is used for comparing the first data information with the second data information and recording the information as third data information; and when the third data information exceeds a preset error threshold value, the alarm module sends out alarm information. According to the alarm system for bolt looseness of the wind turbine tower, omnibearing monitoring of the wind turbine tower is realized, and whether bolts are loosened or not can be monitored and alarmed.

Description

technical field [0001] The invention relates to the field of wind turbine tower bolt loose monitoring, in particular to an alarm system for wind turbine tower bolt looseness. Background technique [0002] Wind energy is an inexhaustible clean and renewable resource produced by nature. Among the existing renewable energy, wind energy is undoubtedly the most competitive, and it is also a new energy that is currently being developed and utilized at home and abroad. one. With the development of wind turbine technology, in order to obtain greater wind power production capacity, increasing the capacity of the unit and increasing the height of the hub have become the trend of wind power development. The wind turbine equipment includes a wind power tower, and a construction platform arranged under the wind power tower. The construction platform is used for operations such as threading, tensioning, closing joints, and fastening bolts inside the wind power tower. [0003] In order t...
