Description

Technical Field

[0001] The invention relates to a multiple-pressure type cabin cover positioning device. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. The wind turbine nacelle covers all components in the nacelle and isolates them from the outside. The nacelle cover is usually made of glass fiber reinforced plastic. As an important component of a wind turbine generator set, the nacelle cover is a protective structure of the wind turbine generator set, enabling the wind turbine generator set to work normally in harsh meteorological environments. When installing existing nacelles, they often require a support mechanism for positioning. However, the stability of the existing positioning support mechanism is still poor after clamping, so it is necessary to improve the stability of the supporting positioning structure. Summary of the invention

The transmission gear of the present invention is a gear that can be raised by the rotation of the steering column and a gear that can move relative to the steering column, and the gear that can move relative to the steering column can be raised to actuate the steering gear, thereby ensuring that the steering column is in a state of stability.

[0006] Furthermore, the upper ends of the floating blocks are fixedly connected to the lower sides of the floating plates through connecting rods.

[0007] Furthermore, sliding engaging grooves are respectively provided on both sides of the floating groove; sliding engaging rods are respectively provided on both sides of the floating block; and the sliding engaging rods are slidably engaged with the sliding engaging grooves up and down.

[0008] Furthermore, the lower support seat is a downwardly protruding arc-shaped plate structure; the upper floating seat is an upwardly protruding arc-shaped plate structure; the lower support seat and the upper floating seat form a hoop structure.

[0009] Furthermore, the upper side surface of the lower support seat and the lower side surface of the upper floating seat are coated with a wear-resistant coating.

[0010] Furthermore, a rubber anti-slip pad is provided at the lower end of the pressure rod.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention drives the upper floating seat to move downward through the floating mechanism, so that the lower support seat and the upper floating seat support and position the end of the cabin cover, and then drives the floating threaded cylinder and the floating plate to move downward by rotating the adjusting screw, thereby driving multiple floating blocks to move downward in the floating groove, thereby driving multiple pressing rods to press and position the cabin cover, thereby increasing the structure and strength of the cabin cover positioning and improving the stability of the structure.

[0013] 2. The present invention drives the driving motor to drive the driving gear to rotate through the driving shaft, and the driving gear drives the rotating gear to rotate through the chain, thereby driving the driving threaded column to rotate, so that the sliding block moves up and down in the limiting sliding groove, so that the upper floating seat moves up and down, thereby realizing positioning adjustment and convenient driving.
