Description

Shock-proof noise-reducing wind motor

Technical Field

The utility model relates to a wind energy conversion system especially relates to a noise reduction type wind energy conversion system of moving away to avoid possible earthquakes.

Background

Wind energy is a clean renewable energy source, and compared with other energy sources, the wind energy has the advantages of large reserve, wide distribution and inexhaustibility. The development and utilization of wind energy can not only relieve the problem of resource shortage, but also protect the ecological environment. Therefore, the wind turbine is widely applied today with obvious energy problem, but the existing wind turbine has the problem of too much vibration and noise.

Disclosure of Invention

In order to solve the above problems, the present invention provides a wind turbine with vibration-damping and noise-reducing functions, which has an object to provide a wind turbine with vibration-damping and noise-reducing functions.

In order to achieve the above object, the utility model provides a pair of noise reduction type wind energy conversion system of moving away to avoid possible earthquakes realizes like this: a shock-absorbing noise-reducing wind turbine comprises blades, a hub, a cabin, a tower, a shock-absorbing noise-reducing shell, a lightning rod and a grounding cable. The blade is fixedly connected with the hub, the hub is fixedly connected with the engine room, and the shock-absorbing noise-reducing shell comprises a protective shell, a sound-absorbing interlayer, a sound-insulating clamping plate and a rubber vibration-absorbing layer.

By way of further illustration, the rubber vibration absorbing layer is circumferentially arranged on the outer wall of the nacelle.

By further illustration, the sound insulation splint is arranged around the outer wall of the rubber vibration absorption layer.

By further illustration, the sound absorption interlayer is arranged on the outer wall of the sound insulation splint in a surrounding mode, and sound absorption materials are placed in the sound absorption interlayer.

As a further illustration, the outer wall of the sound absorption interlayer is a protective shell.

For further explanation, the top of the protective shell is provided with a lightning rod, the protective shell is fixedly connected with the lightning rod, the lower end of the lightning rod is connected with a grounding cable, the lower end of the grounding cable is grounded, and the protective shell is fixedly connected with the tower frame.

The beneficial results of the utility model are that, this wind energy conversion system can reduce vibrations, reduces the noise that wind energy conversion system during operation sent to life has been prolonged, noise pollution has been reduced.
