Description

Technical Field

[0002] Modern buildings often involve large-volume concrete construction, such as high-rise building foundations, large equipment foundations, water conservancy dams, etc. Its main characteristics are large volume, small surface coefficient, concentrated heat release of cement hydration, and rapid internal temperature rise. When the temperature difference between the inside and outside of the concrete is large, temperature cracks will occur in the concrete, affecting the structural safety and normal use. Therefore, it is necessary to control the temperature inside the concrete through a temperature control device.

When the technical solution is in use, when it is detected that the temperature of the inner cavity of the large-volume concrete is too high, the refrigerator transmits cold air to the cooling pipe through the serpentine cold air pipe, and indirectly reduces the temperature of the inner cavity of the large-volume concrete by reducing the temperature of the cooling pipe, which can quickly and timely reduce the temperature of the inner cavity of the large-volume concrete, and avoid the problem of large-volume concrete cracking caused by excessive temperature of the inner cavity of the large-volume concrete. With respect to the above technical solution, although the solution completes rapid cooling of the concrete, when detecting the temperature, the position of the temperature sensor is fixed, and it is impossible to complete the detection according to the concrete of different depths. In addition, the temperature sensor cannot be cleaned, moved and taken out when not in use, which is inconvenient when in use. Utility Model Content

The movable tube 8 is composed of a plurality of wires, and the electric heating wire is energized to heat the water inside the base 1. After the temperature is heated, the temperature inside the concrete needs to be controlled. A temperature measuring mechanism 22 is fixedly installed inside the movable tube 8, and an electric wire 23 is fixed on the temperature measuring mechanism 22. A drainage hole 21 is opened on the top of the base 1, and the drainage hole 21 is connected to the cavity 12. A water pumping pipe 18 is fixedly installed between the water pump 2 and the base 1.
