Embodiment Construction

[0036] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 and figure 2 As shown, the small wind power generator used for toys or teaching in the present invention includes a base 1 , a pillar 2 , a generator 3 , blades 40 and a wind turbine 4 . in:

[0038] The base 1 is made of a metal material embedded in a plastic shell, and is a circular chassis (also can be in other shapes such as a square) with sufficient weight, which can make the whole wind turbine be placed stably.

[0039] Pillar 2 can be a hollow aluminum column, and the lower end is detachably fixedly connected with the connecting hole in the middle part of base 1 through connecting piece 10 (such as: plastic positioning bar), and the other end is also connected through connecting piece 20 (such as: screw and Nut) is detachably fixedly connected with the fuselage shell, because the connection of th...

Abstract

A wind turbine rotor having variable blade pitch is provided. According to one embodiment, the wind turbine rotor includes a hub defining a predetermined number of openings, the hub further including a rotatable adjustment layer defining a predetermined number of slots, wherein the slots corresponds to the openings; and one or more blades secured in the hub, each of the one or more blades including a blade root, and a protrusion extending from the blade root, and wherein the protrusion of each of the one or more blades is engaged by a corresponding slot of the adjustment layer, wherein rotation of the adjustment layer translates the protrusions of each of the one or more blades, thereby rotating each of the one or more blades about the longitudinal axis. The rotor may be removably secured to a generator shaft by a spring, allowing easy adjustment of the rotor for educational use.

Description

technical field [0001] The present invention relates to a toy or a teaching appliance, more specifically, to a small wind-driven generator used for toys and teaching. Background technique [0002] The working principle of the wind turbine is to convert the wind energy in the swept area of ​​the blade into electrical energy. Therefore, the parameters of the blade play a key role in the wind generator. The main purpose of the mold used for toys or teaching is to facilitate students to understand the relationship between the parameters of the blades and the power of the wind turbine. For this reason, a wind turbine that is easy to assemble and change various parameters is needed. It is different from wind turbines that are actually used to generate electricity. However, the wind generators currently used for toys or teaching have simple functions, cannot effectively change the pitch angle of the blades, and have the problem of inconvenient assembly and changing various paramet...
