Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1, which shows a schematic view of an existing wind turbine installation, the wind turbine installation comprises a tower 1 and a wind wheel, the wind wheel is installed on the top of the tower 1, and the tower 1 is supported and installed on a foundation 2. In fig. 1, the fan blades are small in size due to the height limitation of the tower 1.

As shown in FIG. 2, a schematic representation of the reinforced tower of the present application is shown. The reinforced tower comprises an outer cylinder 12, wherein the outer cylinder 12 is arranged outside the original tower 1, and a cementing material such as concrete is filled between the original tower 1 and the outer cylinder 12. In order to improve the bonding strength and the shear strength of the cementing material and the original tower drum 1 and the outer drum 12, bonding ribs 13 can be arranged on the outer wall of the original tower drum 1 and/or the inner wall of the outer drum 12, and the bonding ribs 13 can be welded or bonded with the outer wall of the original tower drum 1 and the inner wall of the outer drum 12. According to the wind driven generator, the outer barrel is arranged on the outer side of the original tower barrel, and the cementing material is arranged between the original tower barrel and the outer barrel to form the reinforced tower barrel, so that the tower barrel is larger in size and stronger in bearing capacity, and a new wind driven generator facility can be built above the tower barrel.

In order to fixedly connect the tower drum at the top, the top of the reinforced tower drum is provided with a pre-buried layer 31. A hole may be formed in the center of the pre-buried layer 31 to correspond to the hole in the center of the original tower 1, and an embedded part 33 that may be wrapped by a cementing material is disposed in the pre-buried layer 31. As shown in fig. 3, the embedded part 33 includes a circular embedded plate, the top end and the bottom end of the embedded plate are respectively provided with an upper screw 34 and a lower screw 35, and the upper screw 34 and the lower screw 35 can be connected to the embedded plate by welding. In order to enhance the connection strength between the embedded plate and the cementing material, tie bars 36 may be further disposed on both sides of the embedded plate. The embedded part 33 is in threaded connection with the connecting pieces at the bottom end of the fan tower and the top end of the reinforcing tower through an upper screw rod 34 and a lower screw rod 35 respectively, so that a new fan tower is arranged at the top end of the reinforcing tower in a connecting mode.
