Description

Technical Field

[0001] This utility model relates to the field of concrete temperature control technology, specifically a construction temperature control device for large-volume concrete for wind turbine foundations. Background Technology

[0002] The rapid development of wind power technology and the continuous increase in the single-unit capacity of wind turbines have placed higher demands on the load-bearing capacity and stability of wind turbine foundations. As a crucial component of wind power systems, the quality of wind turbine foundations directly impacts the safe operation and economic benefits of the entire wind farm. Mass concrete, due to its excellent integrity, durability, and impermeability, is widely used in the construction of wind turbine foundations. However, due to its large volume, small surface area, concentrated heat release during cement hydration, and rapid internal temperature rise, temperature cracks can occur when the internal and external temperature differences exceed a certain range, affecting the structural safety and reliability. Simultaneously, winter construction faces various adverse factors that are not considered under normal temperature conditions, such as reduced temperature slowing down cement hydration; water freezing below 0℃ halting hydration and reducing concrete strength growth; and the expansion of approximately 9% in freshly poured concrete due to freezing, which can cause early-strength concrete with low strength to crack due to freezing stress. Therefore, a temperature control device for the construction of mass concrete for wind turbine foundations is needed. Utility Model Content

[0003] The purpose of this invention is to provide a construction temperature control device for large-volume concrete for wind turbine foundations, in order to solve the problems mentioned in the background art.

The horizontal moving hooks move along the frame, and the vertical moving hooks move along the horizontal moving rods to adjust the position of the stove.

[0009] A temperature sensor is installed in the concrete layer below the furnace. The temperature sensor is used to detect the center temperature and surface temperature of the concrete layer. When the center temperature is higher than the surface temperature, the telescopic frame moves the furnace closer to the concrete layer. When the center temperature is lower than the surface temperature, the telescopic frame moves the furnace away from the concrete layer.

[0010] Preferably, the telescopic frame includes a fixed frame disposed on the vertical moving hook, a guide rod inserted on the fixed frame, a movable frame disposed on the guide rod, a cross support rod disposed on the movable frame, heat-conducting fins disposed on the cross support rod, a limiting block disposed at the other end of the guide rod, and a telescopic rod disposed on the movable frame and connected to the vertical moving hook.

[0011] Preferably, the cross-shaped support rod is used to support the furnace, the telescopic rod is used to move the cross-shaped support rod, thereby moving the furnace away from or closer to the concrete layer, and the heat-conducting fins are used to improve heat conduction.

[0012] Preferably, the fixed frame is further provided with a furnace fixing component.

[0013] Preferably, the furnace-fixing component includes a furnace-fixing threaded rod inserted into the fixed frame, a turntable disposed on the furnace-fixing threaded rod, and a rotating rod disposed on the turntable.

[0014] Preferably, when the rotating rod is rocked, the fixed furnace threaded rod abuts against the furnace, fixing the furnace in place.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the setting of horizontal and vertical moving hooks, allows for rapid adjustment of the furnace position during the movement of the horizontal and vertical moving hooks, thereby changing the heating position.

The setting of telescopic frames adjusts the distance between the furnace and the concrete layer, ensuring that the temperature inside and outside the concrete remains consistent and maintains a suitable air temperature, which is suitable for concrete development.

The internal and external temperatures of the concrete layer 2 are kept consistent.
