Blade strength safety monitoring device based on wind power generation

Abstract

The invention provides a blade strength safety monitoring device based on wind power generation, and relates to the technical field of wind power equipment. A fixing mechanism is mounted on the right side of the fan blade; a locking mechanism is mounted on the left side of the fan blade; a stretching mechanism is mounted at the front end of the locking mechanism; a collecting mechanism is installed below the fixing mechanism, the stretching mechanism is installed through a fixing base and a positioning piece, a stretching cable is stretched on the surface of a main body, the stretching cable is kept tight through a spring on the left side, and when blades are blown by wind, the blades swing to change the tensile force borne by the stretching cable, so that the blades are prevented from being damaged. And meanwhile, the tensile force borne by the tensile cable is reflected through the displacement of the connecting plate, so that the deformation degree of the blade is reflected, and the problems that the blade of the wind driven generator is driven by wind power to drive the motor main shaft to rotate, the blade also bears large force, the blade deforms, aging is gradually generated, and large potential safety hazards are hidden are solved.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a blade strength safety monitoring device based on wind power generation. Background technique [0002] In recent years, as the research on clean energy has gradually been put on the agenda, the construction of wind farms has gradually spread. With the erection of a large number of wind turbines, the safety issues such as the strength and stability of wind turbines have become increasingly serious. [0003] However, as far as the current traditional safety monitoring device is concerned, it mainly monitors and protects the main body of the wind turbine and the motor. When the wind is strong, the blades of the wind turbine drive the main shaft of the motor to rotate under the drive of the wind. The blade itself is also subjected to a large force, causing the blade to deform and gradually age, and there are potential safety hazards. Because the maintenance personnel a...

Problems solved by technology

[0003] However, as far as the current traditional safety monitoring device is concerned, it mainly monitors and protects the main part of the wind turbine and the motor. When the wind is strong, the blades of the wind generator drive the motor shaft to rotate under the wind force. The blade itself is also subject to a relatively large force, causing the blade to deform and gradually age, posing a greater potential safety hazard; at the same time, as mentioned above, when the blade is aging and not maintained in time, it is easy to Due to the distance between the maintenance personnel and the wind turbine, it is difficult to arrive at the scene for maintenance in time after the alarm, and the broken blades will easily cause damage to the main body of the generator and even cause casualties
