[0002] Because of their large size, heavy weight, and high requirements for overhead cranes, the circular wind turbine tower segments are generally prefabricated outdoors. In winter, the low outdoor temperature leads to a longer concrete setting time, slower early strength development, and reduced mold turnover efficiency and production capacity. It can also cause problems such as surface cracks due to inadequate insulation, which can affect the quality of the segments. If the cracks are severe and not properly repaired, it may even compromise structural safety. Summary of the Invention

The vertical support frame consists of multiple vertical steel pipes arranged in a cylindrical shape, with rings fixed at the top and bottom of each vertical steel pipe. The horizontal support frame is set inside the top ring, and the horizontal support frame is fixedly connected to the vertical support frame; The thermal insulation tarpaulin is tied and fixed to the outside of the horizontal and vertical support frames, covering and supporting the horizontal and vertical support frames to form a closed hollow space, which is used to cover the cast-in-place circular wind turbine composite tower segments. A temperature sensor is installed below the horizontal support frame; a heating belt fixing plate is fixed on the vertical support frame, and a silicone rubber heating belt is fixed on the heating belt fixing plate; A transformer and a temperature controller are installed on the outside of the thermal insulation tarpaulin.

[0012] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 The present invention will be described in further detail below.
[0013] This invention discloses a maintenance device for the segments of a circular wind turbine tower, comprising a horizontal support frame 1, a vertical support frame 2, and a silicone rubber heating belt 3. The vertical support frame 2 includes multiple vertical steel pipes arranged in a cylindrical shape, with circular rings fixed at both the top and bottom of each pipe. The horizontal support frame 1 is located inside the top circular ring and is a hexagonal frame with connecting steel pipes arranged diagonally across the hexagon. Both the horizontal support frame 1 and the vertical support frame 2 are made of hollow stainless steel tubing. The horizontal support frame is fixed within the top circular ring of the vertical support frame.
[0014] The insulating tarpaulin is tied and fixed to the outside of the horizontal support frame 1 and the vertical support frame 2. The insulating tarpaulin covers the horizontal support frame 1 and the vertical support frame 2, and is supported by the horizontal support frame 1 and the vertical support frame 2 to form a sealed hollow space. In use, the cast-in-place circular wind turbine tower segments are covered with the insulating tarpaulin.
[0015] A temperature sensor 5 is installed below the horizontal support frame 1, and a suspension point 6 is fixed to the top of the horizontal support frame 1, through which the suspension point 6 passes. A heating belt fixing plate 4 is fixed to the vertical support frame 2, and a silicone rubber heating belt 3 is fixed to the heating belt fixing plate 4.
[0016] A transformer 9 and a temperature controller 11 are installed on the outside of the thermal insulation tarpaulin. A temperature sensor 5 is electrically connected to the temperature controller 11 via a temperature sensor line 7, which runs from the vertical support frame 2 and the horizontal support frame 1. The transformer 9 is electrically connected to the temperature controller 11. A heating belt line 8 connects the silicone rubber heating belt 3 to the transformer 9. A power connector 10 is connected to the transformer 9. The transformer 9 is energized through the power connector 10, and the transformer 9 transmits electrical energy to the silicone rubber heating belt 3 through the heating belt line 8. The temperature controller 11 is electrically connected to the transformer 9. The temperature controller 11 can set the curing temperature and curing time. Based on the temperature signal and temperature rise rate transmitted by the temperature sensor 5, the temperature controller 11 can control the transformer 9 to adjust the power, thereby controlling the temperature rise rate. When the temperature exceeds the set temperature by 2°C, the power to the transformer 9 can be cut off, ceasing heating. When the temperature falls below the set temperature by 2°C, heating can be restarted, repeating this cycle until curing is complete. Both the transformer 9 and the temperature controller 11 can be installed on the vertical support frame 2.
[0017] The implementation principle of a whole-circle wind turbine hybrid tower segment maintenance device disclosed in this invention is as follows: After the cast-in-place circular wind turbine tower segments are finished, the surface is covered with geotextile, which must completely wrap the mold. Use an overhead crane to hang the lifting point 6 and lift the curing device onto the mold that needs curing, covering the entire mold. Set the curing temperature and curing time, and start the curing process.
[0018] Throughout the curing process, the temperature controller 11 can control the transformer 9 to adjust the power by transmitting the temperature signal and the rate of temperature increase through the temperature sensor 5, thereby controlling the rate of temperature increase. When the temperature exceeds the set temperature by 2°C, the transformer 9 can be controlled to cut off the power and stop heating. When the temperature drops below 2°C, it can be reheated, and the cycle repeats. After the curing is completed, do not lift the curing device directly. Wait until the temperature stabilizes and stops decreasing before lifting the curing device and immediately cover the mold with plastic sheeting. After the temperature drops to room temperature, the subsequent demolding work can be carried out.
[0019] This invention patent provides excellent heating and insulation effects, which can appropriately shorten the concrete setting time and increase early strength in winter, greatly benefiting mold turnover and production capacity. Simultaneously, its excellent heating and insulation effects can significantly reduce cracks on the surface of the circular wind turbine tower segments caused by rapid temperature loss, improving the surface quality of the segments. Furthermore, it achieves automatic temperature setting and control, automatic temperature sensing, automatic heating, and automatic power adjustment, essentially realizing automated curing. This is of great significance for promoting the automation and intelligent curing of this emerging component, making it a highly useful, practical, and practically significant invention.
[0020] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
