[0001] This utility model relates to the field of construction technology, and in particular to a temperature control device suitable for large-volume concrete structures. Background Technology

[0002] In modern construction engineering, large-volume concrete structures are widely used. However, after pouring, the cement hydration reaction inside large-volume concrete generates a large amount of heat, causing the internal temperature of the concrete to rise. If the temperature is not properly controlled, temperature cracks can easily occur, affecting the safety and durability of the structure.

[0003] Common temperature control methods include pre-embedded cooling water pipes and surface insulation, but these methods have some shortcomings: for example, the cooling water pipes are not arranged precisely enough and the heat dissipation efficiency is low; the surface insulation materials are not firmly fixed and are easily damaged, making it difficult to achieve effective and precise temperature control of large-volume concrete.

[0004] In view of the problem that the temperature control effect of large-volume concrete structures in the existing technology is not good, those skilled in the art have been looking for solutions. Utility Model Content

The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0024] Please refer to Figure 1 and Figure 2 As shown, the temperature control device for large-volume concrete structures includes: at least one cooling unit, a cooling water circulation system, a temperature sensing unit, and a display and control terminal 4. Each cooling unit includes at least two layers of cooling pipes 11. The cooling water circulation system includes a number of water pumps 21 and a cooling tower 22, the same number as the number of cooling units. Each water pump 21 is connected to the inlet of all cooling pipes 11 in a cooling unit, and the cooling tower 22 is connected to the outlet of all cooling pipes 11 in all cooling units. The temperature sensing unit includes several temperature sensors 31 that are matched with each layer of cooling pipes 11. The display and control terminal 4 establishes communication with the temperature sensing unit to obtain and display the temperature of each layer of large-volume concrete structure in real time. Based on the obtained temperature, it adjusts the water pumps 21 on the corresponding layer of cooling pipes 11 in a timely manner to regulate the flow rate of cooling water entering the cooling pipes 11 of that layer.

[0025] like Figure 1 As shown, when the temperature control device is applied to a large-volume concrete structure, the uppermost cooling pipe 11 is arranged in an arc-shaped loop in the large-volume concrete structure layer, thereby increasing the contact area between the large-volume concrete structure and the cooling pipe 11 and improving the cooling effect.

[0026] like Figure 2 As shown, when the temperature control device is applied to a large-volume concrete structure, each cooling unit is set in a structural layer of a section of the large-volume concrete structure, and the cooling pipes 11 in each cooling unit are set in layers in structural layers of different depths of the current section of the large-volume concrete structure to achieve temperature regulation at different depths of the large-volume concrete structure.

[0027] Preferably, each cooling unit also includes several copper sheets 12 spaced apart on each layer of cooling pipe 11, thereby greatly increasing the heat exchange area between the cooling pipe 11 and the subsequently poured concrete and enhancing the heat dissipation efficiency.

[0028] The display and control terminal 4 can display information such as temperature and cooling water flow rate at various measuring points inside the concrete on a screen, facilitating viewing and control by construction personnel. Based on the display and control terminal 4, the sensed temperature data can be displayed in real time, and the cooling water circulation can be automatically controlled, increasing the timeliness and accuracy of temperature control.

[0029] Understandably, the temperature sensors 31 of the temperature sensing unit are installed at different locations and depths within the large-volume concrete. These temperature sensors 31 are connected to the display and control terminal 4 via signal transmission lines to monitor the temperature at different locations within the concrete in real time. By installing multiple temperature sensors in each structural layer containing the cooling pipes, the internal temperature changes of the concrete can be more accurately reflected, providing reliable data support for temperature control.

[0030] Specifically, when the temperature obtained by the display and control terminal 4 is high and reaches a preset threshold, it controls the water pump 21 on the corresponding cooling pipe to increase the flow rate of cooling water entering the cooling pipe, thereby accelerating the flow of cooling water to remove heat from the structural layer where the cooling pipe is located. Specifically, the cooling water in the cooling tower 22 is pumped into the corresponding cooling pipe by the water pump 21. During the flow of the cooling water within the cooling pipe, it absorbs heat from the interior of the structural layer where the cooling pipe is located. Then, the cooling water, carrying the absorbed heat, flows out to the cooling tower 22 for cooling and is then recycled.

[0031] Furthermore, the display and control terminal 4 establishes communication with the temperature sensing unit based on the signal transmission line.

[0032] Preferably, the inlets of all cooling pipes 11 in each cooling unit are connected to the water pump 21 via inlet connectors, and the outlets of all cooling pipes in each cooling unit are connected to the cooling tower 22 via outlet connectors. Preferably, each cooling pipe inlet is equipped with an inlet switch to control whether water enters.

[0033] In this embodiment, each cooling pipe is a stainless steel cooling pipe with an inner diameter of 2cm.

[0034] To better understand the temperature control device of this utility model applicable to large-volume concrete structures, the following detailed explanation will be based on an example where each cooling unit includes three layers of cooling pipes, specifically upper, middle, and lower layers, and the temperature control device is applied to a large-volume concrete structure:

[0035] Before pouring the large-volume concrete structure, the number and arrangement of cooling units are determined based on the size and shape of the structure. The area where the large-volume concrete structure will be poured is divided into different zones, and a cooling unit is installed in each zone. Next, temperature sensors are fixed in designated locations to ensure good contact with the concrete. Then, a signal transmission line is used to connect the temperature sensors to the display and control unit. Next, the inlet and outlet connectors of the cooling pipes of each cooling unit are connected to the water pumps and cooling tower of the cooling water circulation system. The sealing of the entire cooling unit and cooling water circulation system is checked to ensure no leakage. Then, the concrete is poured. After the concrete is poured, the display and control terminal begins to collect data from the temperature sensing units. When the temperature data collected by the temperature sensing units reaches a preset threshold, the water pumps in the corresponding layer of the structure are activated to increase the flow rate of cooling water, accelerate heat dissipation, and ensure that the internal temperature of the concrete remains within a reasonable range.

[0036] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments.

[0037] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.

[0038] In summary, the temperature control device for large-volume concrete structures provided by this utility model, through the in-depth design of the cooling unit of the temperature control device, is designed to include at least two layers of cooling pipes, with temperature sensors installed on each layer of cooling pipes to obtain the temperature at the location of each layer of cooling pipes in a timely manner. This allows for timely adjustment of the temperature at the location of each layer of cooling pipes by regulating the water pumps on the corresponding layer of cooling pipes and adjusting the flow rate of cooling water entering that layer of cooling pipes. This enables more accurate and efficient control of the temperature of large-volume concrete structures, effectively preventing the generation of temperature cracks and improving the quality of the project.

[0039] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
