[0003] The mainstream tower structure for wind turbine generators is the steel cylinder tower, which consists of 3-5 tapered sections, with adjacent tapered sections connected by flange bolts.

[0004] The tower of a wind turbine contains steel components such as a steel grating platform, elevator rails, and supports. Because the tower is located outdoors in windy areas, frequent maintenance is required to ensure reliable operation. However, the existing welded and fixed steel components inside the tower are inconvenient to disassemble and replace. Furthermore, these inconveniently disassembled components can obstruct the passage of objects during later maintenance work, causing inconvenience. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figure 1-4 This utility model provides a technical solution: an energy-saving steel structure weld-free joint reinforcement structure, comprising:

[0037] Column 1;

[0038] I-beam 2, with its end abutting against the side wall of column 1;

[0039] The adapter 3 includes an inner connector 31 and a movable connector 32. The adapter 3 is symmetrically arranged on both sides of the web 21 of the I-beam 2.

[0040] The inner connecting member 31 has an "L"-shaped cross-section and includes a first connecting plate 311 and a second connecting plate 312. The first connecting plate 311 is fixedly installed on the web plate 21 by a first bolt 313. The web plate 21 has a slotted hole 211 arranged along the length of the I-beam 2. The first bolt 313 is disposed in the slotted hole 211. The movable connecting member 32 includes a side end plate 321, a front panel 322, and a movable plate 323. The side end plate 321 contacts the second connecting plate 312. Bolt 324 passes through side end plate 321 and second connecting plate 312 and is threaded onto column 1. A hinge part 3222 is provided at the end of panel 322. The length of the hinge part 3222 extending out of the end face of panel 322 is equal to the thickness of side end plate 321. Movable plate 323 is rotatably connected to hinge part 3222. A first through hole 3231 is provided on movable plate 323. When movable plate 323 is rotated and placed on the surface of panel 322, the position of the first threaded hole 3221 on panel 322 corresponds to the first through hole 3231.

[0041] The connection between the internal steel structure column 1 and the I-beam 2 of the wind turbine tower is made by a connector 3. The connectors 3 on both sides of the I-beam 2 are connected to the I-beam 2 and the column 1 by bolts, which solves the problem of inconvenience in disassembly, replacement and maintenance caused by the welding fixation of the internal steel structure of the wind turbine tower.

[0042] The inner connecting parts 31 and movable connecting parts 32 of the adapter 3 are adapted to different installation conditions through different assembly methods, so that the adapter 3 can flexibly select different installation methods according to the size of the installation space on the side of the column 1 away from the I-beam 2, thereby improving installation flexibility.

[0043] Two parallel movable plates 323 are provided on the panel 322 to improve the connection strength between the adapter 3 and the column 1.

[0044] The first connecting plate 311 has symmetrically arranged bent edges 314 on both sides, which contact the flange plates of the I-beam 2. The bent edges 314 are effectively positioned to support the inner connecting member 31, preventing the inner connecting member 31 from becoming loose during installation.

[0045] Working principle: See appendix Figure 1-3 When the installation space on the side of column 1 away from I-beam 2 is large and the operation is convenient, the adapter 3 is fixed to column 1 using a "clamp-type" method. Specifically: the movable plate 323 on the movable connector 32 of the adapter 3 rotates to fit against column 1, and the locking bolt passes through the first through hole 3231 and is threaded to column 1. At this time, the side end plate 321 on the other side of the upper panel 322 of the movable connector 32 contacts column 1, and the second bolt 324 passes through the second connecting plate 312 and the side end plate 321 in sequence and is threaded to column 1.

[0046] See appendix Figure 4 When the installation space on the side of column 1 away from I-beam 2 is small and operation is inconvenient, the adapter 3 is fixed to column 1 in a "butt-fitting" manner. Specifically: the movable plate 323 on the movable connector 32 of the adapter 3 rotates to fit against the surface of panel 322, the third bolt 325 passes through the first through hole 3231 and is threadedly connected to the first threaded hole 3221, the movable plate 323 is retracted, and the panel 322 moves towards the side of I-beam 2 to adjust its position so that the hinge part 3222 at the end of panel 322 does not exceed column 1. At this time, the second connecting plate 312 of the inner connector 31 fits against column 1, the side end plate 321 of the movable connector 32 contacts the second connecting plate 312, and the second bolt 324 passes through the second connecting plate 312 and the side end plate 321 in sequence and is threadedly connected to column 1.

[0047] Example 2

[0048] Based on the above embodiments, this embodiment further improves upon the following technical solution: a reinforcing plate 33 is provided between the movable plates 323 of the two adapters 3, and two reinforcing plates 33 arranged in an "X" shape are provided between the two adapters 3.

[0049] When the adapter 3 is fixed to the column 1 using a "clamp-type" method, the movable plates 323 of the two adapters 3 are locked together by the reinforcing plate 33. The locking bolt passes through the first through hole 3231 on the reinforcing plate 33 and the movable plate 323 in sequence and is then threaded to the column 1, further strengthening the connection between the column 1 and the I-beam 2.

[0050] Preferably, the two reinforcing plates 33 are arranged in an "X" shape, which further improves the connection strength of the adapter 3.

[0051] Example 3

[0052] Based on the above embodiments, this embodiment further improves upon the following technical solution: a longitudinal support seat 4 is provided between the column 1 and the I-beam 2. One side of the longitudinal support seat 4 is fixedly installed on the column 1, and the other side is fixedly installed on the flange plate of the I-beam 2.

[0053] The column 1 and the I-beam 2 can be further connected and reinforced by the longitudinal support 4. The longitudinal support 4 is fixed to the column 1 and the I-beam 2 by bolts, so as to achieve welding-free installation.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
