Description

Technical Field

[0001] This utility model relates to the field of concrete construction, specifically to an intelligent temperature control system for cooling water in large-volume concrete. Background Technology

[0002] Mass concrete is a common structural form in construction. Because concrete is a poor conductor of heat, the heat generated by the cement hydration reaction cannot dissipate in time during concrete construction, resulting in a higher internal temperature and a relatively lower surface temperature. This internal and external temperature difference creates a temperature difference between the inside and outside of the concrete. If this temperature difference exceeds the allowable value of the concrete, it will cause temperature cracks on the surface, affecting the safety performance of the concrete structure.

[0003] Temperature control of large-volume concrete by circulating cooling water is one of the most effective methods for temperature control. However, according to construction specifications, the temperature of the cooling water should not be too hot or too cold, as both will have an adverse effect on the temperature control of the concrete. Therefore, a reasonable cooling water system should be designed for the cooling water used for concrete temperature control in order to effectively improve the construction efficiency of concrete temperature control and avoid temperature cracks. Summary of the Invention

[0004] This invention addresses the problems of existing technologies by providing an intelligent temperature control system for cooling water in large-volume concrete.

[0005] This utility model provides an intelligent temperature control system for cooling water in large-volume concrete. During the pouring of the large-volume concrete, cooling water pipes are laid out. Each cooling water pipe includes an inlet and an outlet, both connected to a circulating water tank. A circulating water pump is installed inside the circulating water tank and connected to the inlet. The system is characterized by: a water level sensor and a temperature sensor installed inside the circulating water tank; the circulating water tank is connected to an inlet pump and an outlet pump; the inlet pump is connected to an inlet pipe for pumping external water into the circulating water tank; and the outlet pump is connected to an outlet pipe for pumping water from the circulating water tank to the outside. The intelligent temperature control system also includes a control system connected to the water level sensor and the temperature sensor to acquire the water level and temperature of the circulating water tank. The control system is also connected to a first control module and a second control module. The first control module controls the opening and closing of the inlet pump, and the second control module controls the opening and closing of the outlet pump.

[0006] Preferably, the circulating water pump is a submersible pump, and both the inlet pump and the outlet pump are centrifugal pumps.

[0007] Preferably, a cooling water pool is provided, the capacity of which is more than 10 times that of the circulating water tank. The cooling water pool provides an external water source for the inlet pump, and the outlet pump pumps the water source from the circulating water tank to the cooling water pool.

[0008] Preferably, the control system is a microcontroller or a PLC, and both the first control module and the second control module are relays, which are used to turn the inlet pump and the outlet pump on or off.

[0009] The working principle of this utility model is as follows: According to the relevant construction specifications for large-volume concrete, the inlet water temperature should be controlled within a reasonable range when cooling water is circulated through the cooling pipes. If it is too high, the cooling effect of the cooling water will be reduced; if it is too low, it will cause a large temperature difference between the pipe wall and the concrete. Therefore, it is necessary to optimize and control the water temperature of the cooling water pipes. If the volume of the cooling water source is too large, the energy required for temperature regulation will be greater. Therefore, a circulating water tank is designed to treat the cooling water source. The circulating water tank has a relatively small capacity, which is convenient for movement and control. At the same time, the use of a cooling water tank can also achieve effective temperature control.

[0010] The system is equipped with water level and temperature sensors. It detects water level fluctuations and initiates a pumping operation when the water level exceeds the maximum level. This pump removes excess water from the circulating water tank. Conversely, it injects water into the circulating water tank when the water level falls below the minimum level. This combined drainage and injection effectively lowers the temperature of the circulating water tank, especially during the concrete heating stage, where it effectively regulates the temperature of the water.

[0011] During the concrete heating stage, the return water temperature is relatively high, causing the water temperature in the circulating water tank to rise. At this time, hot water is discharged and cold water is injected using the outlet and inlet pumps to regulate the temperature of the circulating water tank. Water level and temperature sensors are used for real-time monitoring, and the control system is used for operation to achieve intelligent control of the circulating water tank, improve the effective control of cooling water, and ensure the regulation of water level and temperature in the circulating water tank.

[0012] The advantages of this utility model are: (1) Set up a circulating water tank and use the circulating water tank to realize reasonable and intelligent control of water temperature. Since the volume of the circulating water tank is relatively small, its temperature control is relatively simple. (2) The water level and water temperature of the water tank are obtained in real time by using water temperature sensor and temperature sensor. Since the water inlet pump and water outlet pump are used, the water body can be exchanged. The water level sensor is used to sense the water level to avoid overflowing when the water level is too high or affecting the cooling water circulation when the water level is too low. (3) Set up a first control module and a second control module. Use the data from the water level sensor and temperature sensor of the control system to control the actions of the first control module and the second control module, so as to effectively ensure the temperature and water volume balance of the circulating water tank.

[0014] The following provides a detailed explanation of the limitations of this utility model.

[0015] This utility model provides an intelligent temperature control system for cooling water in large-volume concrete. During the pouring of the large-volume concrete, cooling water pipes are laid out. Each cooling water pipe includes an inlet 1 and an outlet 2, both connected to a circulating water tank 3. A circulating water pump 4 is installed inside the circulating water tank 3 and connected to the inlet 1. The system is characterized by: a water level sensor 5 and a temperature sensor 6 installed inside the circulating water tank 3; and an inlet pump 7 and an outlet pump 8 connected to the circulating water tank 3. The inlet pump 7 is connected to an inlet pipe 9 for discharging external water. The water source is pumped into the circulating water tank 3. The water outlet pump 8 is connected to the water outlet pipe 10 to pump the water source of the circulating water tank 3 to the outside. The intelligent temperature control system also includes a control system 11. The control system 11 is connected to the water level sensor 5 and the temperature sensor 6 to obtain the water level and water temperature of the circulating water tank 3. The control system 11 is also connected to a first control module 12 and a second control module 13. The first control module 12 controls the opening or closing of the water inlet pump 7, and the second control module 13 controls the opening or closing of the water outlet pump 8.

[0016] Preferably, the circulating water pump 4 is a submersible pump, and the inlet pump 7 and outlet pump 8 are both centrifugal pumps. The submersible pump is connected to the inlet 1, and a cooling water pipe is laid in the concrete between the inlet 1 and the outlet 2. When the cooling water pipe is laid in a multi-loop configuration, the inlet 1 is connected to the inlet of the multi-loop configuration in sequence.

[0017] In the appendix Figure 3 The diagram shows the connection between inlet 1 and the inlet of the three loops, all of which are installed inside the concrete. The outlets of the three loops are connected to outlet 2 (the connection and attachments are shown in the image). Figure 3 (Same as above), the outlet 2 is then connected to the circulating water tank 3.

[0018] Both the inlet 1 and outlet 2 are fixed to the circulating water tank 3 by a fixing device. The circulating water tank 3 has two openings with flanges. The inlet 1 and outlet 2 are connected to one of the openings. The water pipes connecting the inlet pump 7 and outlet pump 8 to the circulating water tank 3 are located in the other opening (not in the same opening as the inlet 1 and outlet 2).

[0019] Preferably, a cooling water pool is provided, the capacity of which is more than 10 times that of the circulating water tank 3. The cooling water pool provides an external water source for the inlet pump 7, and the outlet pump 8 pumps the water source from the circulating water tank 3 to the cooling water pool. The water in the cooling pool can be naturally cooled by the outside air temperature, thereby ensuring the temperature of the water source in the cooling water pool.

[0020] Preferably, the control system 11 is a microcontroller or a PLC, and the first control module 12 and the second control module 13 are both relays, which are used to turn the inlet pump 7 and the outlet pump 8 on or off.

[0021] The control system 11 can acquire the water temperature and water level in the circulating water tank 3, and control the inlet pump 7 and outlet pump 8 according to the water temperature and water level to achieve the condition of water temperature in the circulating water tank 3. The adjustment of water temperature should take priority over the adjustment of water level to ensure that the water level in the circulating water tank 3 is within a reasonable range. On the basis of reasonable water level, the water temperature in the tank can be adjusted.

[0022] The above embodiments are merely preferred embodiments of the present utility model. The protection scope of the present utility model should not be considered as limited to the specific forms described in the embodiments. The protection scope of the present utility model also includes equivalent technical means that can be conceived by those skilled in the art based on the concept of the present utility model.
