Variable-pitch power generation device capable of automatically tracking wind power

Abstract

The invention discloses a variable-pitch power generation device capable of automatically tracking wind power, and belongs to the field of renewable energy. According to the variable-pitch power generation device capable of automatically tracking the wind power, though movement of connecting rods, a separation sleeve slides rightwards, a first connecting piece is separated from the connection of the separation sleeve, and thus, idling is achieved; on one hand, an electric generator can be effectively protected, on the other hand, damage to a speed reducing mechanism can be effectively reduced,and later maintenance is facilitated; and through rotation of an arranged positioning rotating column and under the heat conduction effect of a heat conduction block, generated heat can be effectively conducted into energy storage beads, and the heat is conducted into heat conduction wires, so that an expansion material in an expansion block is promoted to expand, a brake block is tightly jackedon the outer surface of the rotating rod, on one hand, the rotating speed of the rotating rod can be effectively decreased, and on the other hand, damage of the heat to a bearing can be effectively reduced.

Description

technical field [0001] The invention relates to the field of renewable energy, more specifically, to a pitch-variable power generation device that automatically tracks wind power. Background technique [0002] At present, the international energy crisis and continuous environmental deterioration have made countries intensify their efforts to develop new clean energy. Wind power is the clean energy that has the most potential to partially replace traditional fossil energy. In our country, wind power generation is the most realistic choice for the sustainable development strategy of energy and electricity. The mainstream type of wind turbine is the horizontal axis power generation method. This type of unit uses a horizontal axis turbine, and its energy capture efficiency mainly depends on the efficiency of the turbine. [0003] As one of the core parts of the large-scale wind turbine control system, the pitch control system plays a very important role in the safe, stable and...

AI Technical Summary

Problems solved by technology

[0005] However, it is difficult for the existing variable pitch power generation device to automatically track the wind force, resulting in excessive wind force, damage to the main body of the control machine head, and the overall paralysis of the entire wind power system; Mesh fans generally use small non-variable-pitch fans, which cannot change the angle of attack according to different wind speeds, so they cannot achieve maximum efficiency in the full wind speed range

However, most pitch-variable fans use fly-by-wire pitch, which is costly, energy-intensive, and low-reliability for small and medium-sized fans.
