Description

Reflective hemisphere blade high power breeze generator set

The present invention relates to a breeze power generating device, and more particularly to a reflective hemispherical blade high power breeze generator set. Background technique

Wind energy is an inexhaustible green resource. The technology of converting wind energy into electric energy is relatively mature. Wind power generators, that is, wind turbine generators generally include wind turbines and wind blades installed around them. Their operation has certain requirements on wind speed. When the wind speed is 1. 5M/S, the blade rotates, and when it is 3-4, it can generate electricity. Conventional wind turbines usually use spiral blades, and the blades are at a vertical angle to the wind direction. Therefore, the installation height of the spiral blades has certain requirements, otherwise this will not work properly, which makes it impossible to use in most areas. Chinese patent ZL02205368. 9 The disclosed breeze generator with horizontally rotating hemispherical blades overcomes the above-mentioned shortcomings. The reflector-shaped hemisphere blades used in this generator rotate horizontally under the wind to drive the generator assembly to generate electricity. The rotating reflective hemisphere blades greatly reduce the installation height requirements, which creates conditions for the popularization of wind turbines. However, the existing breeze generators with horizontally rotating revolving hemispherical blades have lower installed capacity and cannot meet the operational needs of high-power electrical equipment.

Summary of the invention The object of the present invention is to provide a high-power wind power generator that can meet the operational requirements of high-power electrical equipment, in view of the shortcomings of the existing micro-wind generator installed in the horizontal rotation of the reflective hemisphere.

The reflective hemispherical blade high power breeze generator set of the invention comprises: a reflective hemispherical wind impeller, a breeze generator and a lightning protection device, characterized in that: further comprising a tower column with a step ladder, the tower column is self-supporting At least two layers of the generator set working chamber for the installation of the breeze generator are arranged, and the door of the column column is provided with a door that can enter the working chamber of the generator set; at least one unit with a controller is installed in each working chamber of the generator set. A breeze generator; a reflective hemispherical wind impeller for driving the breeze generator is mounted on the column above the working chamber of each generator set; and the lightning protection device is installed at the top of the column.

A transmission wheel mechanism is disposed between the reflective hemispherical wind impeller and the breeze generator. A speed increaser is disposed between the breeze generator and the transmission wheel mechanism.

A hydraulic clutch is disposed between the speed increaser and the transmission wheel mechanism, and the hydraulic clutch is provided with a clutch controller.

The generator set working chamber is mounted on the tower column by a bracket.

Each of the leaf arms of the reflective hemispherical wind impeller is an adjustable telescopic leaf wall, and each telescopic leaf arm is formed by inserting an inner arm tube and an outer arm tube, wherein the inner arm tube is provided with a ball nut, and the outer arm tube is provided with a ball The ball screw matched with the ball nut in the inner arm tube, one end of the ball screw is connected with the synchronous motor main shaft, and the ball screw rotation and the ball nut are driven by the synchronous motor to promote the axial movement of the inner arm tube along the outer arm tube.

The mating surface of the outer arm tube and the inner arm tube is provided with a keyway matching mechanism for preventing radial rotation between the two. Each of the wind cups of the reflective hemispherical wind impeller is hinged to the end of the leaf arm through the pin shaft, and is provided with a synchronous motor capable of adjusting the rotation angle of the wind bowl blade handle around the pin shaft. With the above structure, the wind bowl can be adjusted by 45 ° rotation. . When the wind strength reaches or exceeds the safety limit, the synchronous motor rotates 45 °, and the vertical "wind" surface of the wind bowl is rotated at a 45 ° angle. At this time, the wind bowl is "winded" face down, reducing the wind force. Its driving force is reduced to achieve the protection of equipment. When the wind is normal, the microcomputer will issue a command, and the synchronous motor will reverse 45 °, so that the wind bowl will return to its original vertical position and it will work normally. The reflective hemispherical blade high-power breeze generator set has the scientific design and reasonable structure, and fully utilizes the characteristic that the reflective hemispherical wind impeller is parallel to the ground and its operation is not affected by the installation height, and the plurality of reflective hemispherical wind impellers are stacked. The method is installed on a tower column, and the reflective hemispherical wind impellers rotate simultaneously under the action of the wind without mutual interference. The transmission wheel driven by each of the reflective hemispherical wind impellers drives the breeze generator to generate electricity, and the output power and power are greatly increased. Can meet the needs of high-power electrical equipment operation. The reflective hemispherical blade high-power breeze generator set has the advantages of small installation area, low installation height requirement, and the advantage of convenient maintenance of the unit.
