Summary of the Invention

[0003] In view of this, the present invention proposes an automatic temperature control device and method for large-volume concrete, aiming to solve the problem in the prior art that the temperature gradient inside large-volume concrete is difficult to accurately control.

[0004] In one aspect, the present invention provides an automatic temperature control device for large-volume concrete, comprising: a wireless temperature measurement unit, a central control unit, and a cooling unit; wherein,

[0005] The wireless temperature measuring unit is embedded in the mass concrete to be measured, and is used to obtain temperature data inside the mass concrete to be measured in real time;

[0006] The cooling unit is arranged in the mass concrete to be tested and is used to deliver cooling medium to the mass concrete to be tested to adjust the medium temperature;

[0007] The central control unit is connected to both the wireless temperature measuring unit and the cooling unit, and is used to receive real-time temperature data sent by the wireless temperature measuring unit and analyze and process the temperature data. When the current temperature data exceeds a preset temperature range, the central control unit is controlled to adjust the flow rate or temperature of the cooling medium so that the temperature inside the mass concrete to be measured is controlled to be within the preset temperature range.

[0008] Furthermore, in the above-mentioned large-volume concrete automatic temperature control device, the wireless temperature measurement unit includes: a wireless transmission module and several sensors; wherein,

It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Device Example:

[0028] See Figure 1 The automatic temperature control device for mass concrete according to an embodiment of the present invention includes: a wireless temperature measuring unit 100, a central control unit 200, and a cooling unit 300. The wireless temperature measuring unit 100 is embedded in the mass concrete to be measured to obtain temperature data inside the mass concrete to be measured in real time. The cooling unit 300 is arranged in the mass concrete to be measured to supply a cooling medium to the mass concrete to be measured to adjust the medium temperature. The central control unit 200 is connected to both the wireless temperature measuring unit 100 and the cooling unit 300 to receive real-time temperature data sent by the wireless temperature measuring unit 100 and analyze and process the temperature data. When the current temperature data exceeds a preset temperature range, the central control unit 200 controls the cooling unit 300 to adjust the flow rate or temperature of the cooling medium to control the temperature inside the mass concrete to be measured to within the preset temperature range.

[0029] Specifically, the wireless temperature measurement unit 100 includes: a wireless transmission module and a plurality of sensors; wherein the wireless transmission module is connected to each of the sensors to transmit the temperature data collected by the sensors to the central control unit 200.

[0030] More specifically, the sensor is a thermocouple or thermistor. By providing multiple sensors, the temperature distribution of each area inside the concrete can be more accurately understood, thereby optimizing the layout and cooling strategy of the cooling unit 300 and improving cooling efficiency.

[0031] The wireless transmission module can adopt Bluetooth, Wi-Fi, Zigbee or other radio frequency technologies. In this embodiment, the wireless transmission method is adopted to reduce the complexity and cost of wiring.

[0032] The central control unit 200 is equipped with a data acquisition module, which connects to each sensor and collects temperature data from them. The data acquisition module typically has a certain storage function, which can temporarily store the collected data. The real-time temperature data recorded by the central control unit 200 can be used to analyze the heat release pattern of concrete hydration, providing data support for future similar projects. Based on this temperature monitoring data, the construction team can better adjust construction parameters and process flows, thereby improving construction quality.

[0033] Central control unit 200 also includes a data processing module for comparing currently collected temperature data with a preset temperature range. Specifically, the data processing module can perform functions such as temperature curve plotting, temperature differential analysis, and historical data comparison to help detect temperature distribution and trends within the concrete.

[0034] In this embodiment, the preset temperature range is determined based on the difference between the internal temperature and the surface temperature of the mass concrete in the actual construction scenario. The purpose is to control the temperature gradient in the mass concrete, reduce the temperature difference between the internal and surface, reduce temperature stress, and thus prevent the occurrence of cracks.

[0035] The central control unit 200 analyzes the temperature data transmitted from the wireless temperature measurement unit 100 and determines whether it exceeds the preset temperature range. If it exceeds the preset temperature range, it adjusts the temperature or flow of the cooling medium in the cooling unit 300 and continues to monitor new temperature data through the wireless temperature measurement unit 100 until the temperature reaches a safe range.

[0036] In this embodiment, the cooling unit 300 includes several cooling water pipes, each arranged along various directions within the mass concrete to be tested. The cooling water pipes can be plastic or metal. The layout of the cooling water pipes needs to be optimized based on the structure's geometry and thermodynamic analysis results to ensure effective temperature control. In this embodiment, cold water is pumped into the cooling water pipes via a water pump system during or shortly after concrete pouring. The cold water flows through the pipes, removing the heat of hydration released by the surrounding concrete.

[0037] Furthermore, the inlet end of each cooling water pipe is connected to an external cooling medium source, and the outlet end is connected to a recovery device. Hot water flowing through the pipe is discharged from the pipe system, recovered by the recovery device, and then cooled and recycled. This not only saves water resources but also improves the efficiency of the cooling system.

[0038] Through this method, the cooling water pipe device can effectively control the temperature gradient in large-volume concrete, reduce the internal and surface temperature differences, reduce temperature stress, thereby preventing the occurrence of cracks, ensuring the overall quality and safety of the structure, and through precise temperature control measures, reducing quality defects and subsequent maintenance costs caused by temperature problems.

[0039] Preferably, the cooling water pipes are arranged in a grid shape to more effectively control the temperature gradient inside the mass concrete and prevent cracks caused by uneven temperature.

[0040] If the temperature inside the mass concrete is higher than the preset temperature range, the flow rate of the cooling medium can be increased by controlling the opening of the flow regulating valve; if the temperature inside the mass concrete is lower than the preset temperature range, the flow rate of the cooling medium can be reduced by controlling the opening of the flow regulating valve.

[0041] Of course, when the temperature inside the bulk concrete is higher than the preset temperature range, the temperature of the cooling medium in the cooling unit 300 can be lowered; when the temperature inside the bulk concrete is lower than the preset temperature range, the temperature of the cooling medium in the cooling unit 300 can be increased.

[0042] In this embodiment, it can also include: an alarm unit; wherein, the alarm unit is connected to the central control unit 200, and is used to send an alarm signal when the temperature data collected by any sensor in the wireless temperature measurement unit 100 exceeds the set temperature range, so that construction personnel can take timely measures to prevent possible quality defects.

[0043] This embodiment may also include a remote communication unit; wherein the remote communication module is connected to the central control unit 200 and is used to send the temperature data collected by the central control unit 200 to a cloud platform or server. Users can access the information on the cloud platform through mobile applications on PCs, mobile phones, or tablets to achieve remote monitoring. This allows construction and management personnel to access real-time data and analysis reports via the Internet, enabling remote management and decision-making. The remote communication unit can be based on a module such as a cellular network (such as 4G / 5G) or Wi-Fi.

[0044] It can be clearly concluded from the above that the automatic temperature control device for large-volume concrete provided in this embodiment detects the temperature data inside the large-volume concrete in real time through the wireless temperature measuring unit, and transmits the temperature data to the central control unit. The central control unit analyzes the received temperature data and determines whether it exceeds the preset temperature range. When the preset temperature range is exceeded, the cooling unit is controlled to adjust the flow and temperature of the cooling medium. The wireless temperature measuring unit continues to monitor the temperature and feeds back the new temperature data to the central control unit until the central control unit determines that the current temperature is within a reasonable range, thereby achieving precise temperature control, which is beneficial to reducing temperature stress and preventing the occurrence of cracks. In addition, the linkage of each unit reduces the probability of operational errors and reaction delays, and improves the safety and reliability of the construction process.

[0045] Method Example:

[0046] See Figure 2 The present invention also provides a method for automatically controlling the temperature of large-volume concrete, comprising the following steps:

[0047] The wireless temperature measurement unit collects the temperature data inside the large volume concrete to be measured in real time and transmits the temperature data to the central control unit;

[0048] The central control unit analyzes the collected temperature data and determines whether the current temperature exceeds the preset temperature range. If the current temperature exceeds the preset range, the central control unit controls the cooling unit to adjust the flow rate and temperature of the cooling medium.

[0049] The wireless temperature measurement unit continues to collect temperature data inside the large volume concrete to be measured, and feeds back the latest collected temperature data to the central control unit. The central control unit controls the cooling unit to adjust the flow and temperature according to the collected temperature data until the central control unit determines that the temperature data is within the preset temperature range.

[0050] The relevant parts of the method embodiment and the above-mentioned device embodiment can be referenced to each other and will not be repeated here.

[0051] In summary, the automatic temperature control method for large-volume concrete provided by the present invention monitors the internal temperature changes of the concrete in real time. The system can dynamically adjust the flow rate and water temperature of the cooling water pipe to achieve precise temperature control and reduce the risk of temperature stress and cracks. The automated system reduces human intervention, improves construction efficiency and accuracy, and provides data support through historical data analysis and optimization of construction parameters. The linkage system not only improves the safety and reliability of the construction process, but also saves resources by optimizing cooling strategies, reduces operating costs, and reduces quality defects and subsequent maintenance costs caused by temperature problems, thereby comprehensively improving project quality and reducing construction risks and costs.
