Problems solved by technology

[0004] Once the support pole of the wind turbine collapses, it is very easy to cause the blades to touch the ground and be damaged, and because wind turbines are usually installed in high mountains, grasslands, Gobi, coastal or offshore places with rich wind energy and sparsely populated places, where animal husbandry is developed in the grassland environment, wind turbines are easy to collapse It endangers the safety of local residents and livestock such as cattle and sheep, resulting in personal or property loss; and in the above-mentioned environment with harsh natural conditions, it is actually impossible to carry out daily frequent inspections, so the collapse of the fan support rod cannot be known in time, causing irreparable damage. economic loss

Abstract

The invention discloses a fan supporting rod collapse monitoring method and device. The method comprises the steps of presetting a collapse and vibration signal judgment mechanism; acquiring vibrationsignals acquired by vibration acquisition devices arranged in a plurality of areas on the support rod, wherein the areas are divided according to the height of the support rod; processing the acquired vibration signals through the judgment mechanism, and judging the collapse condition of the supporting rod; according to the method and the device, the vibration acquisition devices are distributedto acquire the vibration signals of different height areas on the supporting rod, collapse analysis is automatically performed based on a judgment mechanism to obtain a judgment result of the collapsecondition, early warning is timely sent to inform workers to take maintenance measures in time, economic losses are reduced, and personal injury caused by collapse of the fan supporting rod is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a method and device for monitoring the collapse of a fan support rod. Background technique [0002] The wind turbine tower, also known as the wind turbine support rod, is a component that supports the nacelle and the wind wheel. It supports the wind wheel to a height that can better capture wind energy. It is one of the main force-bearing components of the wind power generation device. About ten percent of the cost of the whole fan device, the cost is very high. [0003] During the operation of the fan, the support bar of the fan must not only bear the force and moment transmitted by the wind wheel to the support bar under various wind conditions, but also bear the force and moment of the wind load on the support bar under various wind conditions. It bears the gravity and moment of the wind wheel, propeller hub, nacelle and other components, and the stability of the...
