Liftable wind power generation device

Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a liftable wind power generation device which comprises a cabin and a tower, a through hole is vertically formed in the middle of the cabin, the tower penetrates through the through hole, the cabin and the tower are in sliding connection in the vertical direction, a rotor hub with blades is arranged at the front end of the cabin, and the rotor hub is connected with the wind power generation device. The front end of the rotor hub is provided with a monitoring device, the rear end of the rotor hub is connected with a gearbox, the gearbox is connected with a generator, the cabin is connected with the tower through a horizontal rotating mechanism and a vertical moving mechanism, the cabin is suspended on the tower through a rope, a winding device is arranged in the tower, and the winding device is connected with the generator. The winding device drags the rope, and the monitoring device is connected into a control system of the wind power generation device. By arranging the monitoring device, the state in front of the wind power generation device is monitored in real time, and then according to different conditions, the cabin is controlled to ascend and descend along the tower through the winding device arranged in the tower and the traction rope.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a liftable wind power generation device. Background technique [0002] In the early 1970s, due to the "oil crisis", which caused energy shortages, human beings began to realize the instability and limitation of conventional mineral energy supply, so seeking clean and renewable energy has become an important issue in today's world. As a renewable and non-polluting energy source, wind energy has attracted more and more attention. [0003] A wind power generation device is an electrical device that converts wind energy into mechanical energy, and then converts mechanical energy into electrical energy. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power utilizes natural energy and can be used for a long time. The principle of wind power generation is to use the...

Problems solved by technology

[0004] However, in order to obtain sufficient air volume, the existing wind power generation device usually has its nacelle set at a very high place, and the equipment hoisting cost is high during installation and construction; the nacelle works at a high place, and it is difficult to observe its external conditions at close range in real time (such as surface cracks) damage, etc.); when the internal equipment needs to be repaired and maintained, the staff needs to be lifted up to the sky to carry out the work, and the replacement of spare parts also needs to be uploaded and downloaded multiple times over long distances, which has poor safety and low work efficiency; in the case of extreme weather such as strong winds However, due to its blades and huge size, the wind power generation device will bear a huge force, which is easy to be damaged and cause economic losses; more importantly, the linear velocity of the blade tip of the rotating wind power generation device is very high, Can injure birds when in the flight path of migratory flocks
