Embodiment 1

[0044] A bottom tower with a pre-installed bottom platform, such as Figure 1 to Figure 7 shown, including:

[0045] The tower main body 1 is installed on the tower foundation, and the tower main body is provided with a first connecting piece 11 and a second connecting piece 12;

[0046] The bottom platform 2 is fixed in the main body of the tower in a pre-installed manner. The height of the bottom platform matches the position of the tower door 13 of the main body of the tower. The bottom platform includes a support frame 21 and a platform panel 22. The platform The panel is fixedly mounted on the support frame, the support frame is fixedly connected to the tower body through a first connecting piece, and the platform panel is fixedly connected to the tower body through a second connecting piece;

[0047]The upper platform 4 includes an upper platform frame 40 assembled by a plurality of first support beams 41 and a plurality of second support beams 42, the upper platform fr...

Embodiment 2

[0057] An installation method of a bottom tower, applicable to the bottom tower described in any one of the above-mentioned embodiment 1 and its preferred solution, the method includes:

[0058] Step 1: Obtain the tower body of the bottom tower;

[0059] Step 2: fixing the end of the support frame to the first connector on the inner wall of the tower main body in the tower main body;

[0060] Step 3: Fix and install the platform panels on the support frame in sequence;

[0061] Step 4: The platform panel is fixedly connected to the second connector on the inner wall of the tower main body to complete the pre-installation of the bottom platform;

[0062] Step 5: Fix the upper platform frame on the top of the main body of the tower;

Abstract

The invention discloses a bottom tower with a pre-installed bottom platform and an installation method thereof. By arranging a pre-installed bottom platform in a tower main body, and after the overall installation of the bottom tower is completed, a bottom platform support frame is built, so that the bottom platform is formed. The construction of the wind turbine does not need to be carried out independently in the wind farm. It is only necessary to build a bottom platform support frame for the bottom platform in the bottom tower after the bottom tower is installed and fixed, avoiding the high-risk operation of building the bottom platform. The first support beam and the second support beam through which the upper platform frame passes are detachably and fixedly connected, so that the upper platform frame can be easily disassembled, which facilitates the hoisting of large electrical equipment such as converters. The problem that the bottom platform of the bottom tower in the prior art is easily affected by the wind force of the wind field when it is installed independently, and the problem of tipping over is solved.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a bottom tower with a pre-installed bottom platform and an installation method thereof. Background technique [0002] The converter is one of the main components of the wind turbine. In the wind turbine, the converter is usually installed on the bottom platform of the bottom tower. Due to the large size of the converter, it is generally impossible to pass through the tower door of the tower. It is transported into the tower at the same time, so usually, the bottom platform for installing the converter is independently built before the tower is installed, and then the bottom tower is installed, and then as the tower door is raised, the bottom platform of the bottom tower is It needs to correspond to the tower gate, and it must be raised accordingly, which leads to the bottom platform becoming a towering structure. When the bottom platform is built independently, it is easily...
