[0033] Working Principle: An automatic installation device for tarpaulin coverings of wind turbine nacelles includes a first braking vehicle 1, a second braking vehicle 2, and a lifting plate 3. In use, the power to the second motor 43 is switched on via a control switch on either the first or second braking vehicle 2. The second motor 43 drives the gears in the second gearbox 42 to rotate, which in turn drives the roller shaft 45 to rotate around the bearing, causing the roller 44 to rotate on the track 6. This adjusts the distance between the first and second moving boxes 4 and 5, allowing for the installation of tarpaulins of various sizes. Then, the power to the third motor 47 is switched on, causing it to reverse, which drives the gears in the third gearbox 46 to rotate. This causes the winding rod 48 to rotate in the opposite direction around the bearing 49. The reverse rotation of the winding rod 48 releases the connecting rope 7, which slowly descends under the gravity of the automatic release shell 8. The hook 9 is then lowered to a suitable position, and the hook... 9. Hook the tarpaulin at the four corners of the hanging holes, and then use the third motor 47 to rotate forward to wind up the connecting rope 7, raising the tarpaulin to a suitable height. Then turn on the power to the first motor 16, and use the first motor 16 to rotate forward, thereby driving the gear in the first gearbox 17 to rotate, which in turn drives the threaded rod 18 to rotate, causing the shaft pin 11 on the bottom side of the lifting mechanism to move on the first slide groove 12, thereby allowing the scissor fork 10 to unfold, allowing the lifting plate 3 to slowly rise, stopping when the bottom of the tarpaulin is a suitable distance above the top of the engine room cover. Then start the drive motor in the drive box 14, thereby driving the drive wheel 15 to rotate, and use the rotation of the drive wheel 15 to move the entire device, then move the tarpaulin to the top of the engine room cover, and then use the third motor 47 to rotate in the opposite direction to slowly lower the tarpaulin. When the tarpaulin covers the engine room cover, the engine room cover will provide support for the tarpaulin, thereby allowing the hook to automatically disengage. Then move the entire device out, and the installation is complete.

[0034] The device has a compact structure, reasonable design, and convenient operation. The motor drive can meet the needs of automatic installation of engine room tarpaulins. The hook can be moved freely to adjust its position. It can install tarpaulins of different sizes, has high flexibility, can achieve automatic movement, and can automatically unhook, reducing the labor intensity of workers, greatly improving installation efficiency, saving time, and has strong overall stability. It is very simple and convenient to operate and uses a backup power supply to solve the problem of external power supply.

[0035] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
