Description

A sail type wind energy power automatic conversion device

Technical field:

The utility model relates to a sail type wind energy power automatic conversion device, which belongs to the technical field of wind energy conversion.

Background technique:

Wind energy is an inexhaustible and inexhaustible clean energy. Wind energy conversion is an important way to utilize wind energy. For example, wind power generation has the characteristics of energy saving and environmental protection, and has been widely valued by countries all over the world. Ordinary wind energy conversion equipment is generally of the paddle type, which is developed on the basis of aircraft aerodynamics. In order to increase the power generation energy, it is getting larger and larger, and the diameter of the blade is getting bigger and bigger. The problems are: The larger the diameter of the blade, the slower the rotation speed, because each blade is a whole. On the same blade shaft, the resistance of the blade itself offsets most of the power generated by itself. The larger the diameter, the faster the blade tip goes. The longer the distance, but no matter how fast the blade tip goes, it will not reach the speed of the wind. Therefore: the larger the diameter of the blade, the slower the speed; the paddle wind turbine requires a high speed, the greater the speed, the greater the output power, and The start-up wind speed requirement is also relatively high, and low speed will not produce large energy; the aircraft engine can make the propeller reach a high speed, but it is impossible to use wind energy to drive the wind motor propeller to reach a high speed, resulting in wind energy conversion. low efficiency.

Utility model content:

The purpose of the utility model is to provide a sail-type wind energy power automatic conversion device, which has a reasonable structure, reduces costs, improves wind energy conversion efficiency, and solves the above-mentioned problems in the background technology.

The technical scheme of the utility model is:

A sail-type wind energy power automatic conversion device, comprising a plurality of sails arranged vertically and wind generators connected thereto, said sails include at least one movable sail blade and a matched sail blade shaft, the movable sail blades are set on On the sail blade shaft, the sail blade shaft is eccentrically arranged on the movable sail blade, and the movable sail blade is divided into two parts with different areas.

The circle around which the sails rotate together is divided into an active area and a non-active area by the direction of the wind force. The wind blows to the sails in the active area, and the movable sail leaves hang down to withstand the wind and drive the sails to rotate to do work. The wind blows to the sails in the non-active area. On the top, the movable sail blades are parallel to the wind to reduce resistance and not bear the wind force. They rotate together with the sails and rotate to the work area. The sail shaft is set eccentrically on the movable sail, and the movable sail is divided into two parts with different areas. The greater the difference in area between the two parts, the better the effect of work. However, the weight of the larger part should be equal to or Slightly larger than the weight of the smaller part, it not only ensures that the movable sail blade hangs down in the working area, but also ensures that the movable sail blade is parallel to the wind in the non-working area, because the movable sail blade is parallel to the wind mainly by the weight of the smaller part. Balance the weight of the larger portion of the area.

In order to increase the weight of the smaller part of the active sail, you can set a counterweight on the smaller part to balance the weight of the larger part; or increase the thickness of the smaller part to increase the weight; you can also use different specific gravity materials to make activities The two parts of the sail blade are of different sizes, the larger part has a smaller proportion, and the smaller part has a larger proportion.

A limit rod is set on the rotation path of the movable sail blade, and the position of the limit rod is adjustable to ensure that the rotation range of the movable sail blade is limited within 90 degrees; the position adjustment method of the limit rod can be controlled by a single-chip microcomputer Automatic adjustment, adjusted according to the wind speed, the greater the wind speed, the larger the angle of rotation of the movable sail blades, closer to parallel with the direction of the wind force.

A plurality of movable sail blades are arranged on one sail, and the arrangement mode of the plurality of movable sail blades is arbitrary.

A plurality of sails can be directly arranged on the rotation shaft of the wind generator to drive the rotation of the wind generator, and the plurality of sails can be arranged at a high place through a support frame. It can also be arranged on a turntable, and the shaft of the turntable is connected to a wind generator, which indirectly drives the rotation of the wind generator, so that it is convenient to be arranged in areas with strong winds such as sea surface and flat ground. In order to facilitate the rotation of the turntable, the turntable can be set in a magnetic levitation manner.

The beneficial effects of the utility model are:

①The utility model can generate huge energy at low speed, because the wind force and the sail are positively propelled, and the area of the sail itself can be very large; moreover, the cutting in and out of the sail are also doing work, the sail that does work faces the wind, and the sail that does not do work The sail is automatically converted to be parallel to the wind, and the solidity ratio is large, which can generate huge energy.

② Low wind speed (first-level wind) can start, high wind speed can automatically change the angle of the active sail blade, and it can also operate normally in strong wind to ensure a stable speed.

③ The utility model can replace the paddle-type wind power generation device in the background technology, relies on wind energy for automatic regulation and automatic operation, and has reasonable structure, low cost and high wind energy conversion efficiency.
