Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a heating and humidification curing device and method for full-circle or semi-circular wind power hybrid tower segments. Background Technology

[0002] Because of their large size, weight, and high requirements for overhead cranes, full-circle or semi-circular wind turbine tower segments are generally prefabricated outdoors. In winter, the low outdoor temperature leads to problems such as longer concrete setting time, slower early strength development of concrete, and slower strength development of naturally cured segments. This affects mold turnover and delivery cycle. At the same time, problems such as surface cracks due to inadequate insulation may also occur, which have a certain impact on the quality of the segments. If the cracks are severe and not repaired properly, it may even cause structural safety issues. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a heating and humidification curing device and method for full-circle or semi-circular wind power hybrid tower segments.

[0004] On the one hand, the present invention provides a heating and humidification curing device for full-circle or semi-circular wind power hybrid tower segments, which adopts the following technical solution: A heating and humidification maintenance device for a full-circle or semi-circular wind power hybrid tower segment includes a horizontal support frame, a vertical support frame, a temperature sensor, a humidity sensor, and a temperature and humidity controller. The vertical support frame includes 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 fixed inside the top ring of the vertical support frame; An annular tube is provided around the upper ring of the vertical support frame, and a tarpaulin hook is slidably connected to the lower part of the annular tube. The tarpaulin hook can slide along the circumference of the annular tube. An upper thermal insulation tarpaulin is fixed to the horizontal support frame. The edge of the upper thermal insulation tarpaulin hangs down. A vertical thermal insulation tarpaulin is hung on the tarpaulin hook. The vertical thermal insulation tarpaulin surrounds the outside of the vertical support frame. The upper thermal insulation tarpaulin and the vertical thermal insulation tarpaulin form a closed hollow space. The temperature sensor and humidity sensor are fixed at the bottom of the horizontal support frame, and both the temperature sensor and humidity sensor are electrically connected to the temperature and humidity controller. A heating belt fixing plate is fixed on the vertical support frame, a silicone rubber heating belt is fixed on the heating belt fixing plate, a transformer is fixed on the vertical support frame, the transformer is electrically connected to the silicone rubber heating belt, and the transformer is electrically connected to the temperature and humidity controller. A humidifier interface is fixed on the outer wall of the bottom ring of the vertical support frame, and multiple moisture outlets are opened on the ring.

[0005] Optionally, the horizontal support frame is a hexagonal frame with connecting steel pipes set at the diagonals of the hexagon. Both the horizontal and vertical support frames are made of hollow stainless steel pipes.

[0006] Optionally, the top of the horizontal support frame is fixed with a suspension point that passes through the upper thermal insulation tarpaulin.

[0007] Optionally, a connecting rod is fixed between the inner wall of the annular tube and the outer wall of the upper circular ring of the vertical support frame. The upper thermal insulation cotton tarpaulin hangs down after passing over the annular tube, and the bottom of the hanging edge of the upper thermal insulation cotton tarpaulin is lower than the height of the tarpaulin hook.

[0008] Optionally, the vertical insulation tarpaulin has a break in the vertical height direction, and a zipper is installed at the break. When the zipper is pulled open, the vertical insulation tarpaulin can move along the annular tube, thereby allowing the vertical insulation tarpaulin to be opened and closed.

[0009] Optionally, the humidifier interface is for connecting an external humidifier, and the moisture reaches the interior of the sealed hollow space through the moisture outlet.

[0010] On the other hand, the present invention also discloses a maintenance method for a heating and humidifying maintenance device for a full-circle or semi-circle wind power hybrid tower segment, including a maintenance step before demolding after molding and an outdoor maintenance step after demolding. The curing steps after molding and before demolding include: S1: After the cast-in-place round or semi-circular wind turbine hybrid tower segments are finished, the surface is covered with geotextile so that the geotextile wraps the entire mold. S2: Hoist the curing device onto the mold that needs curing, covering the entire mold; S3: Pull the vertical insulation tarpaulin to cover the entire area and ensure it is tightly closed; S4: Connect the power supply, set the curing temperature and curing time, and start the curing process; S5: During the maintenance process, the temperature and humidity controller controls the transformer to adjust the power by transmitting the temperature signal and the rate of temperature increase through the temperature sensor, thereby controlling the rate of temperature increase. When the temperature exceeds the set temperature by 2°C, the controller controls the transformer to cut off the power and stop heating. When the temperature is 2°C lower than the set temperature, the controller controls the transformer to reheat, and the cycle repeats. S6: After the curing is completed, wait until the temperature stabilizes and stops dropping, then remove the curing device and cover the mold with plastic sheeting. S7: Demolding should be performed after the temperature drops to room temperature; Outdoor maintenance steps after demolding include: T1: Cover the demolded full or semi-circular wind turbine hybrid tower segments with geotextile and transport them to the parking area; T2: Hoist the curing device above the tunnel lining segments to completely cover them; T3: Pull the vertical insulation tarpaulin to cover the entire area and ensure it is tightly closed; T4: Connect the power supply, set the temperature to 20±2℃ and the humidity to ≥95%, and start the curing process; T5: After curing to the specified age, turn off the power to end the curing process; T6: Uncover the vertical insulation tarpaulin and allow the tunnel lining segments to cool to ambient temperature before hoisting away the curing equipment.

[0011] Compared with the prior art, the present invention has the following technical effects: This invention enables automatic setting and control of temperature and humidity, automatic sensing of temperature and humidity, and automatic power adjustment, among other functions. It can comprehensively simulate standard curing temperature and humidity conditions. During winter construction, it can both cure the pipe segments after molding and before demolding, shortening the concrete setting time, improving the early strength of the concrete, and shortening the demolding time, and perform standard curing after demolding, ensuring stable strength growth of the pipe segments outdoors in winter. It can also adjust temperature and humidity as needed, achieving automated and intelligent curing, significantly improving curing efficiency and effectiveness. Because the outer surface of the device is covered with a layer of insulating cotton tarpaulin, it provides excellent insulation, ensuring stable strength growth of the pipe segments during winter construction and reducing cracking, playing a crucial role in improving the curing effect and appearance quality of the pipe segments.

[0014] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 The present invention will be described in further detail below.

[0015] Reference Figure 1 and Figure 2This invention discloses a heating and humidification maintenance device for the segments of a circular or semi-circular wind turbine tower, comprising a horizontal support frame 2, a vertical support frame 1, a temperature sensor 3, a humidity sensor 4, and a temperature and humidity controller 5. The vertical support frame 1 includes multiple vertical steel pipes arranged in a cylindrical shape, with rings fixed at both the top and bottom of each pipe. The horizontal support frame 2 is a hexagonal frame with connecting steel pipes arranged diagonally across the hexagon. The horizontal support frame 2 is fixed within the top ring of the vertical support frame 1. Both the horizontal support frame 2 and the vertical support frame 1 are made of hollow stainless steel tubing. A suspension point 14 is fixed to the top of the horizontal support frame 2.

[0016] An annular tube 6 is provided around the outer perimeter of the upper ring of the vertical support frame 1. A connecting rod 15 is fixed between the inner wall of the annular tube 6 and the outer wall of the upper ring of the vertical support frame 1. A tarpaulin hook 13 is slidably connected to the lower part of the annular tube 6, and the tarpaulin hook 13 can slide along the circumference of the annular tube 6. An upper thermal insulation tarpaulin is fixed on the horizontal support frame 2. The edge of the upper thermal insulation tarpaulin hangs down, passing over the annular tube 6 and hanging down. The bottom of the hanging edge of the upper thermal insulation tarpaulin is lower than the height of the tarpaulin hook 13. The hanging point 14 passes through the upper thermal insulation tarpaulin.

[0017] A vertical insulation tarpaulin is hung on tarpaulin hook 13, and the vertical insulation tarpaulin surrounds the vertical support frame 1. The vertical insulation tarpaulin has a break in its vertical direction, and a zipper is installed at the break. Pulling the zipper allows the vertical insulation tarpaulin to move along the annular pipe 6, thus enabling it to open and close. The upper insulation tarpaulin and the vertical insulation tarpaulin form a sealed hollow space. In use, the completed wind turbine tower segment insulation tarpaulin is covered.

[0018] Temperature sensor 3 and humidity sensor 4 are fixed at the bottom of the horizontal support frame 2. Temperature and humidity controller 5 can be installed on the vertical support frame 1.

[0023] This invention patent can provide curing services for different stages of the forming of full-circle or semi-circle wind turbine hybrid tower segments during winter construction, namely curing before and after demolding. While achieving excellent curing results, it can also completely simulate the standard curing temperature and humidity conditions, providing standard curing for outdoor segments during winter construction. This is extremely beneficial for strength growth and crack prevention, resulting in excellent curing effects. Furthermore, it has multiple functions such as automatic setting and control of temperature and humidity, automatic temperature and humidity sensing, and automatic power adjustment, realizing the automation of segment curing. This is of great significance for promoting the automation and intelligent curing of this emerging component.
