Technical Field

[0001] The utility model relates to the technical field of temperature control, in particular to automatic temperature control equipment for large-volume concrete. Background Art

[0002] Large-volume high-strength concrete dissipates heat naturally slowly. After pouring, the heat of cement hydration is concentrated, and the temperature inside the concrete rises rapidly and by a large margin. In order to prevent the temperature difference between the inside and outside of the concrete from being too large, the existing technology often achieves the effect of temperature control by spraying water on the concrete.

[0003] However, some existing concrete temperature control devices control the temperature by spraying water on the concrete, and the position of the nozzle is relatively fixed, so water can only be sprayed on some parts of the concrete for temperature control, which can easily lead to uneven water spraying and poor cooling effect, which may cause local drying of the concrete surface, resulting in cracks, and further affecting the strength of the concrete.

[0033] The upper end of the water pump outlet pipe 7 is fixedly connected to two connecting pipes 9 , and the two connecting pipes 9 are respectively fixedly connected to the corresponding water pipes 15 and communicate with each other.

[0034] A water collecting trough 17 with a drainage groove is fixedly connected to the upper end of the water collecting trough base 1, a concrete block 18 is placed inside the water collecting trough 17, a cooling water pipe 19 is fixedly connected inside the concrete block 18, and the cooling water pipe 19 is spiral in shape. A first temperature sensor 21 and a second temperature sensor 22 are fixedly connected to the surface of the concrete block 18, and the first temperature sensor 21 extends to the inside of the concrete block 18. Both ends of the cooling water pipe 19 are fixedly connected to the first water pipe 8 and the second water pipe 20, respectively.

[0035] When using the equipment, first use a forklift to transport the equipment to the construction site, then install a cooling water pipe 19 at the center of the concrete block 18 to be poured, and connect the cooling water pipe 19 to the first water pipe 8 and the second water pipe 20, then install the first temperature sensor 21 at the center of the concrete block 18 to be poured, and install the second water pipe 20 at an appropriate position on the surface of the concrete block 18. After the installation is completed, the concrete block 18 is poured.

[0036] Water for cooling the concrete block 18 is added to the cooling water tank 3, and the temperature of the concrete block 18 is detected by the first temperature sensor 21 and the second water pipe 20, so that the temperature distribution of the concrete block 18 can be more comprehensively understood, and abnormal temperature problems can be discovered and handled in time, thereby ensuring the quality and performance of the concrete block 18. When the concrete block 18 generates hydration heat, the temperature detected by the first temperature sensor 21 and the second temperature sensor 22 will increase, and the water pump 5 is started to pass the water in the cooling water tank 3 into the cooling water pipe 19 through the water pump 6 and the first water pipe 8, so as to control the temperature of the concrete block 18 and prevent the temperature of the concrete block 18 from being too high, which may cause cracks in the concrete block 18, and the water in the cooling water pipe 19 is discharged back to the cooling water tank 3 through the second water pipe 20 to circulate the water.

[0037] Water is discharged into the connecting pipe 9 and the water pipe 15 through the water pump outlet pipe 7, and is sprayed out through the nozzle 16 to cool the surface of the concrete block 18. The drive motor 11 is started to drive the threaded rod 12 to rotate reciprocatingly, and the threaded rod 12 drives the sliding block 14 to slide reciprocatingly on the surface of the fixed rod 13. The sliding block 14 drives the two water pipes 15 to move, and the two water pipes 15 drive the corresponding nozzles 16 to move, so as to cool down the surface of the concrete block 18 at multiple locations, improve the uniformity of cooling the concrete block 18, and avoid uneven cooling of the concrete block 18 and the formation of cracks.

[0038] The water is gathered through the water collecting trough 17 and drained into the water collecting trough base 1 through the drainage groove on the surface of the water collecting trough 17 for collection, which can avoid the waste of water resources. When the first temperature sensor 21 and the second temperature sensor 22 detect that the internal and external temperatures of the concrete block 18 are consistent and reduced to a certain level, the power supply of the drive motor 11 and the water pump 5 is disconnected.

[0039] Furthermore, by moving the nozzle 16 up and down to spray water on the surface of the concrete block 18 to cool it down, the uniformity of the cooling of the concrete block 18 can be improved. Spraying water on the surface of the concrete block 18 to cool it down can keep the surface of the concrete block 18 moist, prevent the concrete block 18 from drying out prematurely and cracking, and help to keep the humidity inside the concrete block 18 stable, thereby ensuring the quality and strength of the concrete.

By lowering the temperature of the concrete block 18, the thermal stress caused by the temperature difference is reduced, thereby reducing the risk of cracking of the concrete block 18 and further improving the quality of the concrete block 18.

[0042] Water for cooling the concrete block 18 is added to the cooling water tank 3, and the temperature of the concrete block 18 is detected by the first temperature sensor 21 and the second water pipe 20, so that the temperature distribution of the concrete block 18 can be more comprehensively understood, and abnormal temperature problems can be discovered and handled in time, thereby ensuring the quality and performance of the concrete block 18. When the concrete block 18 generates hydration heat, the temperature detected by the first temperature sensor 21 and the second temperature sensor 22 will increase, and the water pump 5 is started to pass the water in the cooling water tank 3 into the cooling water pipe 19 through the water pump 6 and the first water pipe 8, so as to control the temperature of the concrete block 18 and prevent the temperature of the concrete block 18 from being too high, which may cause cracks in the concrete block 18, and the water in the cooling water pipe 19 is discharged back to the cooling water tank 3 through the second water pipe 20 to circulate the water.

[0043] Water is discharged into the connecting pipe 9 and the water pipe 15 through the water pump outlet pipe 7, and is sprayed out through the nozzle 16 to cool the surface of the concrete block 18. The drive motor 11 is started to drive the threaded rod 12 to rotate reciprocatingly, and the threaded rod 12 drives the sliding block 14 to slide reciprocatingly on the surface of the fixed rod 13. The sliding block 14 drives the two water pipes 15 to move, and the two water pipes 15 drive the corresponding nozzles 16 to move, so as to cool down the surface of the concrete block 18 at multiple locations, improve the uniformity of cooling the concrete block 18, and avoid uneven cooling of the concrete block 18 and the formation of cracks.
