[0006] 3. It is impossible to lower the height of the positioning structure before installation or disassembly, resulting in the need to lift the wind turbine nacelle cover over a relatively high distance, which is not convenient for the installation and disassembly of the wind turbine nacelle cover.

[0022] In addition, the circular anti-loosening rod is provided to position the adjusting screw rod and prevent the adjusting screw rod from loosening; when the staff rotates the adjusting screw rod through the adjusting handle, the adjusting screw rod can push the circular anti-loosening rod downward, so that the adjusting screw rod will rotate only when a force is applied.

[0023] 2. When the adjusting screw rod drives the two positioning flat plates A to move inward in the present invention, the four circular pressing rods can push the two pulling brackets inward, so that when the adjusting screw rod rotates, the two positioning flat plates A and the two positioning flat plates B can move inward simultaneously, positioning the four sides of the wind turbine nacelle cover; when the staff reversely rotates the adjusting screw rod through the adjusting handle, the adjusting screw rod drives the two positioning flat plates A to move outward, and the two positioning flat plates B move outward under the action of the two support springs B, facilitating the rapid separation of the two positioning flat plates A and the two positioning flat plates B from the wind turbine nacelle cover and facilitating the installation and disassembly of the wind turbine nacelle cover.

[0024] 3. When the staff pushes the adjusting handle backward in the present invention, the adjusting handle can automatically press the switch B to make the switch B in the pressed and powered-on state; when the wind turbine nacelle cover after being limited is in a horizontal state and the two positioning flat plates A move to appropriate positions, the front positioning flat plate A can press the switch A, and the alarm works when both the switch A and the switch B are in the pressed state; it is convenient for the staff to know that the limiting accuracy of the wind turbine nacelle cover meets the requirements;

[0025] In addition, when the wind turbine nacelle cover after being limited is not in a horizontal state and the two positioning flat plates A do not move to appropriate positions, the front positioning flat plate A cannot press the switch A, and the alarm does not work, facilitating the staff to know that the limiting accuracy of the wind turbine nacelle cover does not meet the requirements; at this time, the staff can slightly adjust the wind turbine nacelle cover to make it in a horizontal state, and then move the two positioning flat plates A through the adjusting screw rod.

[0026] 4. The setting of the four T-shaped auxiliary frames in the present invention increases the positioning distance between the two positioning flat plates A and the two positioning flat plates B, improving the positioning effect of the wind turbine nacelle cover; before the wind turbine nacelle cover is disassembled, the staff can insert the four T-shaped auxiliary frames into the two rectangular storage holes, which is more convenient for the staff to remove the wind turbine nacelle cover through the hoisting equipment and reduces the hoisting time of the wind turbine nacelle cover;

[0027] In addition, the two rectangular storage holes serve as a temporary storage for the four T-shaped auxiliary frames. After the wind turbine nacelle cover is disassembled, the staff does not need to reset the four T-shaped auxiliary frames. When the next wind turbine nacelle cover needs to be positioned, the staff can connect the four T-shaped auxiliary frames to the four rectangular mounting sleeves. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Specific usage method and function of this embodiment:

[0063] When the present invention is in use, the staff installs the support base 100 on the transport vehicle through bolts, and then places the wind turbine nacelle cover to be transported on the top of the support base 100 through a hoisting device. Then, four T-shaped auxiliary frames 702 are inserted into the four rectangular mounting sleeves 701, increasing the positioning distance between the two positioning flat plates A201 and the two positioning flat plates B502, and improving the positioning effect of the wind turbine nacelle cover. Then, the adjustment handle 305 is rotated. When the staff rotates the adjustment screw rod 302 through the adjustment handle 305, the two positioning flat plates A201 move simultaneously, playing a positioning role on the front and rear sides of the wind turbine nacelle cover. The circular anti-loosening rod 401 is provided to position the adjustment screw rod 302 and prevent the adjustment screw rod 302 from loosening. When the staff rotates the adjustment screw rod 302 through the adjustment handle 305, the adjustment screw rod 302 can push the circular anti-loosening rod 401 to move downward, so that the adjustment screw rod 302 will only rotate when it is stressed. When the adjustment screw rod 302 drives the two positioning flat plates A201 to move inward, the four circular pressing rods 203 can push the two pulling brackets 505 to move inward, so that when the adjustment screw rod 302 rotates, the two positioning flat plates A201 and the two positioning flat plates B502 can move inward simultaneously, playing a positioning role on the four sides of the wind turbine nacelle cover. When the staff pushes the adjustment handle 305 backward, the adjustment handle 305 can automatically press the switch B604, making the switch B604 in a pressed and powered state. When the wind turbine nacelle cover after being limited is in a horizontal state and the two positioning flat plates A201 move to appropriate positions, the front positioning flat plate A201 can press the switch A603. When both the switch A603 and the switch B604 are in a pressed state, the alarm 602 works, which is convenient for the staff to know that the limiting accuracy of the wind turbine nacelle cover meets the requirements. When the wind turbine nacelle cover after being limited is not in a horizontal state and the two positioning flat plates A201 do not move to appropriate positions, the front positioning flat plate A201 cannot press the switch A603, and the alarm 602 does not work, which is convenient for the staff to know that the limiting accuracy of the wind turbine nacelle cover does not meet the requirements. At this time, the staff can slightly adjust the wind turbine nacelle cover to make it in a horizontal state, and then move the two positioning flat plates A201 through the adjustment screw rod 302.

[0064] When the transportation of the wind turbine nacelle cover is completed, the staff reversely rotates the adjusting screw rod 302 by adjusting the handle 305. At this time, the adjusting screw rod 302 drives the two positioning plates A201 to move outwards. Under the action of the two support springs B504, the two positioning plates B502 move outwards, which is convenient for the quick separation of the two positioning plates A201 and the two positioning plates B502 from the wind turbine nacelle cover, facilitating the installation and disassembly of the wind turbine nacelle cover. Then, the four T-shaped auxiliary frames 702 are inserted into the two rectangular storage holes 5051, which is more convenient for the staff to remove the wind turbine nacelle cover by the hoisting equipment, reducing the hoisting time of the wind turbine nacelle cover. At the same time, the two rectangular storage holes 5051 play a role in temporarily storing the four T-shaped auxiliary frames 702. After the wind turbine nacelle cover is disassembled, the staff does not need to reset the four T-shaped auxiliary frames 702. When the next wind turbine nacelle cover needs to be positioned, the staff only needs to connect the four T-shaped auxiliary frames 702 with the four rectangular mounting sleeves 701.
