After docking installation, the conical positioning ring seat (12) and the ring seat alignment groove (13) are embedded and installed.

9. A wind power tower according to claim 9, characterized in that: The positioning protrusion (14) is evenly fixed to the lower part of the conical positioning ring seat (12) in a circular shape, and a protrusion embedding groove (15) is arranged on the bottom side of the ring seat alignment groove (13). After docking, the positioning protrusion (14) and the protrusion embedding groove (15) are aligned and embedded in the installation, the long groove installation hole (16) is arranged in a long groove shape, and a fastening bolt is arranged on the inner side of the long groove installation hole (16). The inner circumference of the ring seat alignment groove (13) is evenly provided with fastening screw holes (17), and the conical positioning ring seat (12) is fastened and installed with the upper docking ring seat (3) by fastening bolts.

10. A wind power tower construction method according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, cage production, during construction, the rib cage is first produced, the support rib column (5) is first arranged and installed on the upper part of the mold base, and then the reinforcing ring seat (7) is installed on the upper part of the support rib column (5) through the hole position and fixed by welding. After completion, the reinforcing rib ring (6) is connected and installed by wire binding and structural welding to form an integrated rib cage; S2, assembling the cage frame. After the rib cage frame is manufactured, the rib cage frame is placed into the interior of the protective sleeve (1) by hoisting. Then, personnel enter the interior of the rib cage frame and use the connecting rib column (8) to cooperate with welding to complete the fixed installation of the rib cage frame and the protective sleeve (1); S3, tower casting, installing a casting mold inside the rib cage frame, and then completing the integral casting and molding of the concrete inner tube (2) by concrete casting, after the concrete inner tube (2) is solidified and formed, removing the mold and completing the connection and installation of the upper docking ring seat (3) and the lower docking ring seat (4), and then completing the connection and installation of the triangular support rod (9) and the inner platform partition (11), and completing the manufacturing and processing of the tower; S4, tower installation, using lifting equipment to lift and install the tower prefabricated parts, after the lower section of the tower is installed and docked with the base, the lifting equipment lifts the tower to the top of the lower tower, adjusts the axial position of the tower, and slowly lowers the tower after the tower is stable, so that the conical positioning ring seat (12) and the ring seat alignment groove (13) slowly approach and fit, and reserve 1-2CM of alignment adjustment space after fitting. At this time, the conical positioning ring seat (12) is only fitted with the upper half of the ring seat alignment groove (13), and the axial fitting limit of the tower is performed at the same time. The tower is allowed to perform axial rotational movement. The upper tower is rotated with the assistance of manual labor, and reference alignment is performed with the aid of the protruding block groove (15). When the hole positions are initially overlapped, the fastening bolts are passed through the long slot mounting holes (16) and initially fastened and installed into the inner side of the fastening screw holes (17). The tower is then slowly lowered with the assistance of bolt guides to install the tower in place. After completion, the bolts at the bolt mounting holes (18) are fastened and installed, and the fastening bolts are then fastened and locked to complete the docking and assembly of the towers. The above operation is repeated to complete the docking and installation of the remaining towers.
