Problems solved by technology

The centrifugal braking device can only be effective in the case of high wind speed, and the speed limit failure is often caused by reasons such as too large or too small tension spring tension
Small wind turbines without mechanical braking devices are prone to stall when the wind speed is high, causing damage to wind turbines and electrical control devices, and even endangering personal safety in severe cases

Abstract

The invention provides a miniature spiral arm tracking mechanical brake system of wind generators, belonging to the technical field of brake speed limit of wind generators, and comprising a brake component, a gyration transmission component, a pull rod, a vertical shaft, a steel wire rope and a gyrator, wherein the brake component is arranged at the rear end of a motor shaft of the generator, covered by the gyrator on the upper end of the vertical shaft and connected with the upper end of the pull rod which penetrates through the gyrator, the gyration transmission component on the vertical shaft is connected with the lower end of the pull rod and fixed with the upper end of the steel wire rope, while the lower end of the steel wire rope is fixed at the bottom of a support system. The brake component and gyration transmission component rotate with the gyrator according to the direction of wind, and the steel wire rope pulls the brake component by the gyrator transmission component and the pull rod to control the rotary speed of the wind generators within a certain range. The invention fills the gap of mechanical tracking control technology on the rotary speed of the miniature wind generators at home and abroad, effectively solves the problem of higher rotary speed of the wind generators with heavy wind, and has simple structure and low manufacture cost.

Description

(1) Technical field [0001] The invention relates to a wind power generator brake speed limiting technology, in particular to a small wind power generator swing arm tracking mechanical braking system. (2) Technical background [0002] At present, the brake speed limiting device applied to some small wind generators is a centrifugal brake brake device, while some small wind generators do not have a mechanical brake device at all. Centrifugal brakes can only be effective when the wind speed is very high, and the speed limit failure is often caused by reasons such as too large or too small tension spring tension. Small wind turbines without mechanical braking devices are prone to stall when the wind speed is high, causing damage to wind turbines and electrical control devices, and even endangering personal safety in severe cases. (3) Contents of the invention [0003] The technical task of the present invention is to provide a small-sized wind-driven generator arm tracking me...
