Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, in particular to a concrete cooling circulating water flow direction intelligent control circulation system. Background Art

[0002] During the construction of large concrete structures, cooling water is often piped through the concrete to reduce internal temperatures. However, as the cooling water absorbs heat from the concrete as it flows through it, it heats up when it leaves the concrete structure. This results in a low temperature at the water inlet and a high temperature at the water outlet. To achieve a more even cooling of the concrete structure, the water inlet and outlet must be constantly swapped, meaning the direction of the cooling water flow within the concrete must be changed.

[0003] Currently, changing the direction of cooling water flow in concrete is primarily accomplished by manually operating a manual or electric valve at fixed intervals (e.g., 12 hours). Automatically changing the direction of cooling water flow based on concrete temperature fluctuations or set time intervals is not yet feasible. This manual method of changing the direction of water flow fails to account for concrete temperature fluctuations and may negatively impact the cooling effect on large concrete structures. Utility Model Content

[0004] In order to overcome the problems caused by the existing manual operation of changing the flow direction of cooling water, the utility model provides a concrete cooling circulating water flow direction intelligent control circulation system, which can solve the various deficiencies of the current manual operation of changing the flow direction of cooling circulating water and realize the intelligent control of the flow direction of concrete cooling circulating water.

[0005] The utility model is implemented as follows: a concrete cooling circulating water flow direction intelligent control circulation system includes a water tank, a water pipe, a water pump, two water temperature sensors, four solenoid valves, and a microcomputer controller. The water pipe is connected to the water tank to form a closed loop. Part of the water pipe is pre-buried in the large-volume concrete structure to be cooled. The two water temperature sensors are located in the large-volume concrete structure to be cooled and are respectively close to two concrete cooling water inlets and outlets of the large-volume concrete structure to be cooled.

[0006] The two sections of water pipes between the water tank and the large-volume concrete structure to be cooled are respectively a water supply pipe and a return pipe. A water pump and a solenoid valve are provided on the water supply pipe, and a solenoid valve is provided on the return pipe. A cross pipe is provided between the water supply pipe and the return pipe, and a solenoid valve is provided on each of the cross pipes to achieve the change of the flow direction of the cooling circulating water in the large-volume concrete structure to be cooled; the water pump, two water temperature sensors, and four solenoid valves are all connected to a microcomputer controller.

[0007] Preferably, the water pipes pre-buried in the large-volume concrete structure to be cooled are arranged in a serpentine shape.

[0008] Preferably, the water pump, the two water temperature sensors, and the four solenoid valves are all connected to the microcomputer controller via wireless communication.

[0009] Preferably, the water pump is a variable frequency water pump.

[0010] The advantages and positive effects of the utility model are:

[0011] 1. The utility model pre-buries water temperature sensors in the concrete near the two concrete cooling water inlets and outlets of the large-volume concrete structure to be cooled and connects them to a microcomputer controller. A cross pipe is set between the water supply pipe and the return pipe, and solenoid valves are respectively set on the water supply pipe, the return pipe, and the cross pipe. The microcomputer controller is also connected to the four solenoid valves. The microcomputer controller reads the temperatures of the two water temperature sensors near the concrete cooling water inlets and outlets of the large-volume concrete structure to be cooled and compares the two. When the absolute value of the difference in concrete temperature near the concrete cooling water inlets and outlets is greater than the user-set temperature value or reaches the user-set time interval, the microcomputer controller controls the different opening and closing actions of the four solenoid valves to achieve intelligent change of the flow direction of the cooling circulation water.

[0012] 2. During the cooling process of a large concrete structure, this utility model can intelligently and automatically change the flow direction of the cooling water according to the temperature difference between the concrete near the two cooling water inlets and outlets of the large concrete structure being cooled, or according to a user-set time interval, thereby achieving a more even cooling of the large concrete structure. This system eliminates the various drawbacks associated with manual manipulation to change the water flow direction and significantly improves the overall cooling efficiency of the concrete.

[0020] See also Figure 1 and Figure 2The embodiment of the present invention provides a concrete cooling circulating water flow direction intelligent control circulation system, including a water tank 6, a water pipe, a water pump 7, a water temperature sensor 1 2, a water temperature sensor 2 12, a solenoid valve 1 4, a solenoid valve 2 5, a solenoid valve 3 8, a solenoid valve 4 9, and a microcomputer controller 10. The water pipe is connected to the water tank 6 to form a closed loop. Part of the water pipe is pre-buried in the large-volume concrete structure 1 to be cooled and arranged in a serpentine shape. The water temperature sensor 1 2 and the water temperature sensor 2 12 are located in the large-volume concrete structure 1 to be cooled and are respectively close to the concrete cooling water inlet and outlet 1 3 and the concrete cooling water outlet 1 of the large-volume concrete structure 1 to be cooled. The cooling water inlet and outlet are located at 11; the two sections of water pipes between the water tank 6 and the large-volume concrete structure 1 to be cooled are respectively a water supply pipe and a return pipe, a water pump 7 and a solenoid valve 4 9 are provided on the water supply pipe, a solenoid valve 1 4 is provided on the return pipe, a cross pipe is provided between the water supply pipe and the return pipe, and a solenoid valve 2 5 and a solenoid valve 3 8 are respectively provided on the cross pipe to realize the change of the flow direction of the cooling circulating water in the large-volume concrete structure 1 to be cooled; the water pump 7, water temperature sensor 1 2, water temperature sensor 2 12, solenoid valve 1 4, solenoid valve 2 5, solenoid valve 3 8, and solenoid valve 4 9 are all connected to the microcomputer controller 10 via wireless communication.

[0021] The specific working process of this utility model is as follows:

[0022] like Figure 1 As shown, in the current state, solenoid valve 1 4 is open, solenoid valve 2 5 is closed, solenoid valve 3 8 is closed, and solenoid valve 4 9 is open. The cooling circulating water is pumped out from the water tank 6 by the water pump 7, flows through the solenoid valve 4 9, and flows to the concrete cooling water inlet and outlet 2 11. After circulating in the large-volume concrete structure 1 to be cooled, it flows out from the concrete cooling water inlet and outlet 1 3, flows through the solenoid valve 1 4 and returns to the water tank 6. The cooling circulating water flows continuously in this way.

[0023] When the microcomputer controller 10 detects that the absolute value of the temperature difference between the water temperature sensor 1 2 and the water temperature sensor 2 12 is greater than the user-set temperature value, or reaches the time interval set by the user, the microcomputer controller 10 controls the solenoid valve 1 4 to close, the solenoid valve 2 5 to open, the solenoid valve 3 8 to open, and the solenoid valve 4 9 to close, thereby realizing the intelligent change of the cooling circulation water flow direction. Figure 2 As shown, the cooling circulating water is pumped out from the water tank 6 by the water pump 7, flows through the solenoid valve 3 8, and flows to the concrete cooling water inlet and outlet 1 3. After circulating in the large-volume concrete structure 1 to be cooled, it flows out from the concrete cooling water inlet and outlet 2 11, flows through the solenoid valve 2 5 and returns to the water tank 6. The cooling circulating water flows continuously in this way. Figure 2 The direction of water flow in the large concrete structure to be cooled is Figure 1 The direction of the cooling water in the water tank 6 and the water pump 7 remains unchanged.

[0024] In addition, the water pump 7 can be selected as a variable frequency water pump 7, and the variable frequency water pump 7 can be adjusted according to the temperature difference between the water temperature sensor 1 2 and the water temperature sensor 2 12. When the temperature difference between the two is greater than 15°C, the microcomputer controller 10 controls the variable frequency water pump 7 to increase the speed to increase the cooling circulation water flow rate, thereby reducing the temperature difference between the water temperature sensor 1 2 and the water temperature sensor 2 12. The speed of the variable frequency water pump 7 is stopped from being increased until the temperature difference between the water temperature sensor 1 2 and the water temperature sensor 2 12 meets the set value, thereby realizing intelligent adjustment and control of the temperature difference between the inlet and outlet of the concrete cooling water, improving the cooling efficiency of the large-volume concrete structure 1 to be cooled, and making the temperature of the cooled concrete structure drop more evenly.
