Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, in particular to an intelligent temperature regulating device for concrete cooling circulating water. Background Art

[0002] Modern architecture often involves large-volume concrete construction, such as high-rise building foundations, large equipment foundations, and water conservancy dams. Large-volume concrete refers to large volumes of concrete with a minimum geometric dimension of at least 1m, or concrete that is expected to produce harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials in the concrete. Due to the large size and low thermal conductivity of large-volume concrete structures, the heat released by the hydration of cementitious materials is difficult to dissipate quickly, and the internal temperature will rise very high, causing deformation and cracking of the concrete structure. Therefore, during the construction process of large-volume concrete, the internal temperature is usually reduced by burying cooling circulating water pipes inside the concrete. Since the cooling circulating water absorbs the heat of the concrete along the way as it flows inside the concrete, the temperature of the cooling circulating water will increase when it flows out of the concrete structure.

[0003] Currently, the temperature of circulating cooling water is typically adjusted by adding ice to the water tank. This method is slow, inefficient, and cannot dynamically adjust the water temperature as the temperature of the cooled structure changes. Furthermore, this artificial ice-adding method cannot promptly account for temperature fluctuations in the cooled structure, potentially negatively impacting the cooling effect on the structure.

[0031] A water temperature regulating tank high water level sensor 10 and a water temperature regulating tank low water level sensor 6 are provided in the water temperature regulating tank 9 , and both the water temperature regulating tank high water level sensor 10 and the water temperature regulating tank low water level sensor 6 are connected to the microcomputer controller 1 .

[0032] As a preferred embodiment, the compressor 22, cold water tank temperature sensor 23, cold water tank high water level sensor 19, cold water tank low water level sensor 17, water supply solenoid valve 21, internal circulation water pump 26, solenoid valve 12, solenoid valve 2 14, electric heating pipe 8, water temperature regulating water tank high water level sensor 10, water temperature regulating water tank low water level sensor 6, external circulation water pump 29, water temperature regulating water tank outlet water temperature sensor 2, water temperature regulating water tank return water temperature sensor 5, and temperature sensor 3 of the structure to be cooled are all connected to the microcomputer controller 1 via wireless communication.

[0033] The specific working process of this utility model is as follows:

[0034] like Figure 1 As shown, in the current state, the microcomputer controller 1 reads the information of the low water level sensor 17 of the cold water tank. If the water level is low, the water supply solenoid valve 21 is controlled to open, and water is supplied to the cold water tank 18 through the cold water tank supply port 20; when the microcomputer controller 1 reads the information of the high water level sensor 19 of the cold water tank, the water supply solenoid valve 21 is controlled to close and water supply is stopped; then the microcomputer controller 1 reads the value of the cold water tank temperature sensor 23. When the value is higher than 5°C (or the user set value), the compressor 22 starts, and the evaporator 24 continuously lowers the water temperature in the cold water tank 18 until the water temperature meets the set value, and the compressor 22 stops working.

[0035] After compressor 22 stops, microcomputer controller 1 controls solenoid valve 2 14 to open, solenoid valve 1 12 to close, and internal circulation water pump 26 to start. Low-temperature water flows from cold water tank 18 back to cold water tank 18 via cold water tank outlet 25, internal circulation water pump 26, solenoid valve 2 14, and cold water tank return port 15. At this time, microcomputer controller 1 reads information from water temperature regulating tank low water level sensor 6 and water temperature regulating tank high water level sensor 10. When the water level in water temperature regulating tank 9 is low, microcomputer controller 1 controls solenoid valve 1 12 to open and solenoid valve 2 14 to close. Low-temperature water in cold water tank 18 is pumped out of cold water tank outlet 25 by internal circulation water pump 26, flows through solenoid valve 1 12, and replenishes water to water temperature regulating tank 9 through water temperature regulating tank inlet 27. When the water level reaches the position of water temperature regulating tank high water level sensor 10, solenoid valve 2 14 opens and solenoid valve 1 12 closes, stopping replenishment of water to water temperature regulating tank 9.

[0036] Then the microcomputer controller 1 reads the value of the temperature sensor 3 of the structure to be cooled, calculates the water temperature value that the water temperature regulating water tank 9 should output according to the control logic set by the user, and reads the water temperature value of the water outlet temperature sensor 2 of the water temperature regulating water tank at the same time, and compares the two. When the outlet temperature of the water temperature regulating water tank 9 is too low, the microcomputer controller 1 controls the electric heating pipe 8 to start, and stops until the outlet temperature of the water temperature regulating water tank 9 meets the requirements; when the outlet temperature of the water temperature regulating water tank 9 is too high, the microcomputer controller 1 controls the solenoid valve 12 to open and the solenoid valve 2 14 to close. When closed, the low-temperature water in the cold water tank 18 is pumped out from the cold water tank outlet 25 by the internal circulation water pump 26, flows through the solenoid valve 12, and flows into the water temperature regulating water tank 9 from the water inlet 27 of the water temperature regulating water tank, thereby gradually reducing the outlet water temperature of the water temperature regulating water tank 9. Until the outlet water temperature meets the requirements, the microcomputer controller 1 controls the solenoid valve 2 14 to open and the solenoid valve 1 12 to close. During this process, if there is too much water in the water temperature regulating water tank 9, the excess water will flow out from the overflow port 11 of the water temperature regulating water tank, and flow back to the cold water tank 18 through the one-way valve 13 and the cold water tank overflow return port 16.

[0037] The utility model achieves the purpose of intelligently regulating the temperature of the cooling circulating water, thereby avoiding various disadvantages caused by manually adding ice into the water tank to change the temperature of the cooling circulating water, and greatly improving the working efficiency of the cooling circulating water temperature regulation.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
