The present invention relates to a nacelle cover including a slide type nacelle door, and more particularly, to a nacelle cover which can be opened and closed by sliding and hinge driving in a state where a nacelle door is coupled to a nacelle cover And the nacelle cover includes the nacelle cover.

Generally, the wind turbine generator is provided with a nacelle assembly and a nacelle cover on the upper part of the main tower, and the rotor and the blade of the nacelle assembly are connected to produce wind power.

The nacelle assembly may be provided with a rotor, a generator, and a speed reducer, which are necessary for power generation. Among them, the speed reducer part is a core part that amplifies the number of revolutions of the rotating rotor by more than 100 times to increase power generation efficiency .

In view of the nature of the speed reducer, the number of revolutions is amplified by a factor of about 100 while receiving the rotational force of the rotor, and accordingly the heat generation is significant, and the damage and failure also frequently occur.

In addition, the accelerator corresponds to a large part among the parts constituting the wind power generation device so as to occupy almost half of the volume of the nacelle assembly.

Therefore, it is virtually impossible for the operator to position and repair the accelerator using the tool at the time of installation and maintenance of the booster. Therefore, when installing the accelerator, the upper portion of the nacelle cover surrounding the nacelle assembly and the nacelle door And during the maintenance and repair, the accelerator is removed from the nacelle assembly through the top of the nacelle cover and the nacelle door.

There is a problem in that the opening and closing process of the nacelle door provided at the upper part of the nacelle cover must be performed promptly and accurately in the process of entering and leaving the above-mentioned booster, and when the nacelle door is closed, There has been a problem in providing a structure that can be sealed so as not to come in.

Therefore, a structure of a nacelle cover and a nacelle door that can open and close the nacelle door provided at the upper part of the nacelle cover can be quickly and accurately required. When the nacelle door is closed, rain or snow enters the nacelle cover A method of providing a structure capable of being hermetically sealed is required.
