Novel windmill

Abstract

The invention relates to a novel windmill used for wind energy conversion. The novel windmill is composed of a fixing strut, a load-bearing bottom plate, a connecting support, an upper fixing plate, a load-bearing bearing, a wind speed controller, blades, a motor and a main shaft, and a magnetic suspension can also be assembled on the windmill. The novel windmill is characterized by being provided with wind speed control blades. The main shaft is installed in the middle in the support. The blades are fixedly connected with the main shaft in a tangent mode. The blades are of arc shapes. The wind speed control blades are hinged to the portion, around the blades, of the support and automatically controlled by a wind speed sensor. The wind speed control blades can swing clockwise or anticlockwise. At ordinary times, the wind speed control blades are opened, and can be turned down automatically only when the wind speed reaches or surpasses the rated wind speed, so that the purpose of increasing the wind energy utilization rate is achieved. The novel windmill has the advantages of being reasonable in structure, efficient, safe, small in occupied area, and capable of adapting to various installing environments, in the using process, an empennage and wind direction orienting equipment do not need to be arranged, and electrical energy is output stably.

Description

technical field [0001] The invention relates to a novel windmill, in particular to a windmill which is safe, efficient and easy to maintain, and has curved blades. Background technique [0002] A windmill is a kind of kinetic energy equipment driven by natural wind. It can convert wind energy into electrical energy with other equipment such as motors. Because the wind direction in the natural environment will change at any time, traditional windmills are equipped with wind direction directional equipment and tail fins. The directional equipment allows The manufacturing cost of the windmill increases, and the maintenance cost also increases accordingly. The installation of the empennage will increase the volume and installation area of ​​the windmill. At the same time, it is necessary to use brackets to support the windmill away from the ground during installation. The manufacturing precision of traditional windmill blades is high. It is difficult to transport, install, a...

[0002] A windmill is a kind of kinetic energy equipment driven by natural wind. It can convert wind energy into electrical energy with other equipment such as motors. Because the wind direction in the natural environment will change at any time, traditional windmills are equipped with wind direction directional equipment and tail fins. The directional equipment allows The manufacturing cost of the windmill increases, and the maintenance cost also increases accordingly. The installation of the empennage will increase the volume and installation area of ​​the windmill. At the same time, it is necessary to use brackets to support the windmill away from the ground during installation. The manufacturing precision of traditional windmill blades is high. Transportation, installation, and installation on the top of a high tower are difficult to maintain, which makes maintenance difficult. Therefore, the current windmills on the market cannot meet people's needs in terms of occupied area, manufacturing cost, and use safety.
