Technical field

The utility model relates to technical field of wind power generation, particularly a kind of power-driven generator leaf.

Background technique

The degree of present energy consumption is too fast, has the fast approach exhaustion of the many energy, must develop the new energy, and at present, our household electricity is derive from thermal power generation and hydroelectric power mostly.As everyone knows, the demand of modern society to the energy is increasing, and more rely on, the utilization of wind energy alleviates the pressure of the energy, wind energy power band gives us new energy mode, wind energy is recycling, clean energy resource, but it is also a kind of energy of instability, it is sometimes still a kind of destructive, domestic research conditions is all the wind-driven generator based on Three-blade, utilize blower interior structure to limit the rotation of blower fan, thus restriction wind energy is to the destructiveness of wind-driven generator, especially for coastal, the wind speed of sea wind is all very high, especially hurricane, wind-driven generator is unserviceable wind energy just.

Current fan blade, during low wind, capacity factor is low, and generator cannot be protected again when wind-force is too fast not burnt, and needs to produce a kind of fan blade protecting generator.

Model utility content

The purpose of this utility model is the shortcoming overcoming prior art, provides the power-driven generator leaf that a kind of applicability is comparatively strong, can suppress maximum speed.

The purpose of this utility model is achieved through the following technical solutions: a kind of power-driven generator leaf, comprise base, left half vane and right half vane, left half vane and right half vane are arranged at the top of base, base is up big and down small circular cone structure, left half vane and right half vane are all in globoidal structure, left half vane and right half vane are centrosymmetric about the axis of base, left half vane and right half vane are locked into a single integrated structure by box and pin locking element, the bottom surface of left half vane and right half vane joint is provided with blade retaining thread hole, this blade retaining thread hole is fixedly connected with by fixing spiral shell button with base, the place of bottom center of base is provided with the rotor fixing threaded hole that can be fixedly connected with generator amature, the blade face of left half vane and right half vane is respectively arranged with vent, in each vent, vent valve is installed.

Described left half vane and the inner side of right half vane are respectively arranged with the deep floor that many substantially horizontals extend, and the cambered surface carrying over left half vane and right half vane that deep floor keeps width consistent is arranged.

Described left half vane and right half vane all adopt macromolecule or fibrous composite.

Described left half vane and right half vane are epoxy resin or high-strength nano material.

The quantity of described vent is not less than one, and the aperture of each vent is 0 ~ 5cm.

Described left half vane and the turning radius of right half vane are 0.9cm ~ 200cm, are highly 5cm ~ 300cm.

The utility model has the following advantages:

1. blade can realize lighting design largely, thus is applicable to various wind speed.

2. blade can be used for combination type wind power generation, and namely the blade of many different sizes and the motor of different capacity carry out combination generating, can play the effect effectively utilizing different wind speed environments.

3. possess vent, and regulate the ventilation size of vent by vent valve, can maximum speed be suppressed, thus protection motor can not burn because rotating too fast, significantly improves the working life of motor.

4, the inner side of left half vane and right half vane is respectively arranged with the deep floor that many substantially horizontals extend, the cambered surface carrying over left half vane and right half vane that deep floor keeps width consistent is arranged, increase the mechanical strength of left half vane and right half vane, improve the structure stability of left half vane and right half vane simultaneously, thus reduce vibrating noise.In addition, owing to arranging deep floor, require to reduce to the processing technology of left half vane and right half vane, therefore, reduce manufacturing process difficulty to a certain extent.

In figure: 1-base, the left half vane of 2-, the right half vane of 3-, 4-vent, 5-vent valve, 6-fixes spiral shell button, 7-rotor fixing threaded hole, 8-box and pin locking element, 9-deep floor.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.

As depicted in figs. 1 and 2, a kind of power-driven generator leaf, comprise base 1, left half vane 2 and right half vane 3, left half vane 2 and right half vane 3 are arranged at the top of base 1, base 1 is up big and down small circular cone structure, as shown in Figure 3, left half vane 2 and right half vane 3 are all in globoidal structure, left half vane 2 and right half vane 3 are centrosymmetric about the axis of base 1, left half vane 2 and right half vane 3 are locked into a single integrated structure by box and pin locking element 8, the bottom surface of left half vane 2 and right half vane 3 joint is provided with blade retaining thread hole, this blade retaining thread hole is fixedly connected with by fixing spiral shell button 6 with base 1, the place of bottom center of base 1 is provided with the rotor fixing threaded hole 7 that can be fixedly connected with generator amature, the blade face of left half vane 2 and right half vane 3 is respectively arranged with vent 4, in each vent 4, vent valve 5 is installed, vent valve 5 is that semi-circular adjustment or other irregularity regulate, play and change release wind-force, slow down vane stress, suppress the object of rotating speed, therefore restriction is not made to the specific design of aperture adjustment valve.
