Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a temperature control and cooling device for large-volume concrete. Background Technology

[0002] In the field of construction engineering, the application of large-volume concrete is becoming increasingly widespread. However, the hydration process of cement generates heat of hydration, causing the internal temperature of the concrete to rise rapidly. After reaching its peak temperature, the temperature begins to drop, and the resulting thermal stress has a significant impact on the concrete structure. When the thermal stress exceeds the ultimate tensile strength of the concrete, cracks will form in the concrete structure. Once these cracks form, they will seriously impair the integrity, impermeability, and durability of the concrete structure.

[0003] Traditional methods for temperature measurement and control of large-volume concrete have many drawbacks. Using ordinary or electronic thermometers, the thermometers are inserted into the concrete at different depths after pouring, and temperature data is read periodically. This method is simple to operate, but has low measurement accuracy, requires frequent manual measurements, is labor-intensive, and is prone to human error. Thermocouples are a commonly used temperature measuring element; by embedding the thermocouple probe in the concrete, the internal temperature of the concrete can be measured. Thermocouple temperature measurement is relatively accurate, but it also requires manual data collection and recording, resulting in low efficiency. Another method is to pre-embed cooling water pipes in the concrete before pouring. When the internal temperature of the concrete rises, cold water is circulated through the cooling water pipes to remove heat from the concrete, thereby lowering the temperature. The layout and flow rate of the cooling water pipes need to be designed and adjusted according to the volume of the concrete and temperature changes. The temperature of the concrete is regulated by controlling the water flow time and flow rate. Generally, the water flow rate is higher in the early stages after concrete pouring to quickly reduce the peak temperature. As the concrete temperature decreases, the water flow rate is gradually reduced until it is stopped. This method requires experienced technicians to operate and adjust; otherwise, it's prone to over-cooling or under-cooling. Alternatively, covering the concrete surface with insulation materials like straw mats or burlap sacks can reduce heat loss and control the temperature difference between the inside and outside of the concrete. This method is simple and easy to implement, but its insulation effect is limited, and it's not ideal for controlling the temperature of large-volume concrete. All these methods require significant human intervention, which is not only labor-intensive but also inefficient. Staff need to frequently perform temperature measurements and data analysis, which can easily lead to oversights and errors. Furthermore, due to differences in judgment criteria, different personnel may make different judgments and decisions based on their own experience and understanding, resulting in inconsistent temperature control effects.

[0004] Among the published patents, patent number CN201921399030.9, entitled "A Temperature Control Device for Large-Volume Concrete," a device provides low-temperature water through a storage tank. Cooling water pipes are embedded in the concrete layer, and a circulation pump is installed. The circulation pump delivers the low-temperature water from the storage tank to the cooling water pipes, transferring the heat generated by the hydration heat of the concrete to the low-temperature water in the cooling pipes. This allows for real-time temperature control to cool the concrete, preventing large temperature differences between the inside and outside of the concrete. This avoids internal stress or tensile forces that could damage the concrete structure, thus improving the quality of large-volume concrete. The device features a simple structure, reasonable design, and low cost, and provides real-time temperature control, improving the quality of large-volume concrete. The high precision of soil temperature control aims to improve the quality of large-volume concrete and recover water from the cooling pipes, thus saving water and energy. However, in the above scheme, a water temperature sensor is installed on the water storage tank to check the water temperature inside. The top of the water storage tank is equipped with an inlet pipe, which is equipped with an inlet valve and a water supply temperature sensor. The temperature sensor is not located inside the concrete, making it impossible to monitor the internal temperature of the concrete in real time. During the circulating cooling process, it is impossible to better monitor the internal temperature of the concrete in real time, thus making it impossible to control the start and stop of the circulating cooling system. The circulating cooling device must be kept on continuously, increasing the operating cost of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a temperature control and cooling device for large-volume concrete, which improves real-time monitoring of the internal temperature of concrete. It also employs automated temperature control technology for large-volume concrete and, through the installation of a water cooling system, achieves intelligent monitoring and control of the temperature difference between the surface and the interior of the concrete. This allows the cooling water to carry away the heat from the concrete, truly realizing a controllable cooling process for the internal temperature of large-volume concrete.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a large-volume concrete temperature control and cooling device, characterized in that: it includes a cooling pipe, which is installed inside the concrete; a pressure stabilizing device is installed on one side of the concrete, and the pressure stabilizing device is connected to the cooling pipe through a connecting pipe; a water tank is installed on one side of the pressure stabilizing device, and the water tank is connected to the pressure stabilizing device through a circulation pipe, and a circulation pump is installed on the circulation pipe; a circulation pipe is installed on the cooling pipe and connected to the water tank; multiple metal protective pipes are installed inside the concrete, and an automatic temperature sensor is installed inside each metal protective pipe; a control system is installed on one side of the concrete, and the control system includes a data acquisition terminal electrically connected to the automatic temperature sensor; an intelligent controller is installed on one side of the data acquisition terminal, and the intelligent controller is electrically connected to a control valve and a circulation pump.

[0007] The beneficial effects of this solution are as follows: By setting up a cooling system consisting of cooling pipes, pressure stabilizing devices, water tanks, and circulating pumps, the concrete can be effectively cooled and its temperature controlled. Multiple automated temperature sensors within the metal protective pipes work in conjunction with the control system to achieve real-time and accurate monitoring of the concrete's internal temperature. A data acquisition terminal collects temperature information, and the intelligent controller automatically controls the operation of the control valves and circulating pumps based on the temperature data, improving the intelligence and automation level of temperature control. This better ensures the construction quality of large-volume concrete, reduces the occurrence of temperature-related problems, and provides strong support for the safety and reliability of building projects.

[0008] Furthermore, an inlet pipe is provided at the upper end of the water tank. A temperature detector and a control valve are installed on the inlet pipe. The control valve is electrically connected to the temperature detector, which can monitor the temperature of the liquid entering the water tank in real time to ensure its accuracy. Automatic control can be achieved through electrical connection. When the temperature does not meet the set requirements, the control valve can respond and adjust in time, avoiding the delay and error of manual intervention, and greatly improving the accuracy and efficiency of temperature control.

[0009] Furthermore, the metal protective tube is a thin-walled copper tube. Copper has excellent thermal conductivity, enabling it to quickly and accurately transfer the temperature inside the concrete to the internal temperature sensor, improving the accuracy and real-time performance of temperature measurement. Copper also possesses high strength, and the thin-walled design minimizes the impact on the concrete structure while meeting strength requirements. It is also less prone to damage during construction. Additionally, copper has a certain degree of corrosion resistance, maintaining stable performance over a longer period, ensuring the reliable operation of the temperature monitoring system. This choice of a thin-walled copper metal protective tube aligns with current technological advancements in the demand for high-performance protective tubes, providing strong support for temperature monitoring and control of large-volume concrete.

[0010] Furthermore, the water tank is a cooling water tank, which can actively lower the water temperature to ensure that the water supplied to the cooling pipes has a lower temperature, thereby cooling the concrete more effectively, improving the efficiency and effect of temperature control, better addressing the high temperature problem that may occur in large-volume concrete, and avoiding the adverse effects of excessive temperature on concrete quality. The cooling water tank can flexibly adjust the water temperature according to actual needs, enhancing the adaptability and controllability of the temperature control system, helping to achieve more precise and stable temperature control, and ensuring the safety and durability of the concrete structure.

[0011] Furthermore, the cooling pipes can be arranged in single or multiple layers to achieve more precise temperature gradient control. This allows for targeted cooling adjustments to concrete in different areas and at different depths, thereby better ensuring the temperature uniformity and stability of the entire concrete structure. This flexibility can adapt to a wider range of engineering needs and complex environmental conditions, improving the adaptability and reliability of temperature control technology for large-volume concrete.

[0012] Furthermore, the pressure stabilizing device is equipped with an overflow pipe connected to the water tank. When the pressure inside the pressure stabilizing device is too high, the excess fluid is discharged back to the water tank in time through the overflow pipe, which plays a role in relieving pressure and thus effectively maintaining the stability of the system pressure, ensuring that components such as cooling pipes are not damaged due to excessive pressure.

[0013] Furthermore, the intelligent controller is electrically connected to an automated temperature sensor and thermometer, which can compare the temperature inside and outside the concrete. It can acquire and synchronously compare the temperature data inside and outside the concrete in real time, so that relevant personnel can clearly and intuitively understand the temperature difference. Based on the comparison results, temperature control measures can be adjusted more precisely, and the intensity and timing of cooling or heating can be adjusted to better ensure the quality of concrete and avoid the occurrence of problems such as temperature cracks.

[0015] Figure 2 It is a cross-sectional view of the concrete. Detailed Implementation

[0016] The reference numerals in the accompanying drawings include: water tank 1, control valve 2, temperature detector 3, inlet pipe 4, circulation pump 5, pressure stabilizing device 6, overflow pipe 8, cooling pipe 9, connecting pipe 10, metal protective pipe 11, circulation pipe 12, thermometer 13, pressure gauge 14, control system 15, data acquisition terminal 16, intelligent controller 17, concrete 18, and automated temperature sensor 19.

[0017] Example 1 is basically as shown in the appendix. Figure 1-2 As shown: A large-volume concrete temperature control and cooling device includes a cooling pipe 9, which is a curved structure installed inside the concrete 18. The cooling pipe 9 can be configured with single-layer or multi-layer bends as needed. A pressure stabilizing device 6 is installed on one side of the concrete 18. The pressure stabilizing device 6 is a pressure stabilizing valve. The pressure stabilizing device 6 is connected to the cooling pipe 9 through a connecting pipe 10. A water tank 1 is placed on one side of the pressure stabilizing device 6. The water tank 1 is a chilled water tank. The water tank 1 is connected to the pressure stabilizing device 6 through a circulation pipe 12. A circulation pump 5 is installed on the circulation pipe 12 to ensure fluid circulation. The cooling pipe 9 is connected to the water tank 1 through a circulation pipe to form a complete circulation loop.

[0018] Metal protective tubes 11 are inserted at multiple predetermined locations on the concrete 18. These metal protective tubes 11 are thin-walled copper tubes with good thermal conductivity and protective performance. An automated temperature sensor 19 is placed inside the metal protective tube 11 to monitor the temperature inside the concrete 18 in real time. This ensures accurate real-time temperature monitoring data inside the concrete 18 and also allows for the reuse of the automated temperature sensor 19.

[0019] A control system 15 is installed on one side of the concrete 18. The data acquisition terminal 16 in the control system 15 is electrically connected to the automated temperature sensor 19 to acquire temperature data in a timely manner. The intelligent controller 17 is electrically connected to the control valve 2 and the circulating pump 5 to achieve precise control of the entire cooling system.

[0020] A water inlet pipe 4 is installed at the top of the water tank. A temperature detector 3 and a control valve 2 are installed on the water inlet pipe 4. The control valve 2 is electrically connected to the temperature detector 3. The opening and closing degree of the control valve 2 is automatically adjusted according to the detected water temperature, so that the water in the water tank 1 can be replenished as needed. By replenishing water of different temperatures, the water temperature in the water tank can be adjusted to maintain it within a suitable range. As the water in the water tank is continuously used or reduced due to evaporation, replenishing water can maintain the water level in the water tank and ensure a sufficient water supply.

[0021] The overflow pipe 8 on the pressure stabilizing device 6 is connected to the water tank 1 to ensure stable system pressure. During operation, the automatic temperature sensor 19 transmits the temperature data inside the concrete 18 to the data acquisition terminal 16 in real time. The data acquisition terminal 16 further transmits the data to the intelligent controller 17. The intelligent controller 17 compares the temperature data with the set standard value, and then automatically adjusts the operating status of the circulating pump 5 and controls the circulation temperature of the circulating pipe to achieve precise control of the temperature of the concrete 18. At the same time, through the electrical connection between the controller and the automatic temperature sensor 19 and the thermometer 13, the temperature inside and outside the concrete 18 can be compared in real time, providing a basis for optimizing the temperature control strategy, thereby ensuring the construction quality and performance of the large-volume concrete 18.

[0022] Water cooling can be paused when the temperature difference between the metal protective tube 11 and the temperature measured by the thermometer 13 is no greater than 15°C. When the temperature difference between the metal protective tube 11 and the temperature measured by the thermometer 13 is greater than 15°C, the water cooling system should be restarted. The advantage of this is that it avoids unnecessary cooling when the temperature of the concrete 18 is already close to the ideal state, thereby reducing energy consumption and equipment wear and tear, and lowering operating costs. Restarting the water cooling system when the temperature difference reaches a certain level again ensures that the temperature inside the concrete 18 can be effectively controlled, maintaining a good cooling effect and ensuring the quality and performance of the concrete 18. It also enables cooling operations to be carried out on demand, improving the utilization efficiency of the equipment.
