Small rainproof wind power generating device

Abstract

The invention discloses a small rainproof wind power generation device, which comprises a fan frame and a small generator. The fan is installed above the small generator. There are several doors, each door is equipped with fan blades, and the fan blades on each door are hinged with the doors and open in the same direction; the fan frame is provided with a top cover, and the top cover is provided with concave and convex surfaces , the concave surface is located at the top, the convex surface is located at the bottom, and the top cover is detachably connected with the fan frame; the beneficial effects of the present invention are: reasonable design, simple structure, small generator, small occupied land area, and through the fan on the door. The hinged setting between the leaves and the door can reduce the demand for wind strength. Even a low-intensity wind can make the fan frame rotate, and the fan frame is provided with a top cover to prevent rainwater from splashing on the main shaft and the fan frame. On the door, it can prevent rust and corrosion and increase the service life.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a small rainproof wind power generating device. Background technique [0002] Wind power is the conversion of wind kinetic energy into electrical energy. As a clean and renewable energy source, wind energy has attracted more and more attention from all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. Wind has long been People use - mainly to pump water, grind flour, etc. through windmills, and now, people are interested in how to use wind to generate electricity. [0003] The principle of existing wind power generation is to convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electric kinetic energy. This is wind po...

AI Technical Summary

Problems solved by technology

[0004] Existing wind power generation devices are various, but noise and visual pollution are ubiquitous; they occupy a large area of ​​land; they are unstable, uncontrollable, and troublesome to maintain; the current cost is still high, and they are prone to rust and corrosion. Corrosion is mostly caused by long-term rain erosion. Although some equipment is sprayed with anti-rust paint on the surface, because the equipment is exposed to sunlight, the anti-rust paint will be damaged or peeled off after being blown by wind and rain. Re-spraying is more troublesome and costly
