Description

Technical Field

[0001] This application relates to the field of concrete construction technology, and in particular to concrete temperature control circulation systems and methods. Background Technology

[0002] During concrete pouring, the heat generated by the hydration reaction is difficult to dissipate quickly, causing heat to accumulate inside the concrete and leading to an abnormal increase in internal temperature. When the ambient temperature is low, the temperature difference between the inside and outside of the concrete further increases, and the resulting thermal stress may exceed the crack resistance of the concrete, causing cracks and affecting the stability and durability of the concrete structure.

[0003] Traditional methods control the internal temperature difference of large-volume concrete by arranging cooling pipe assemblies within the concrete. After concrete is poured, its temperature undergoes dynamic changes; therefore, the water temperature in the cooling pipe assemblies needs to be adjusted accordingly to effectively control the internal temperature of the concrete. Typically, controlling the water temperature in the cooling pipe assemblies requires the installation of circulation pipelines and refrigeration or heat pump equipment, which regulates the temperature of the medium passing through the cooling pipe assemblies.

[0004] However, effectively controlling the temperature of large-volume concrete requires a large flow rate of cooling medium, which typically necessitates large-scale refrigeration or heat pump equipment. Operating these large systems is not only costly but also consumes a significant amount of electricity. Summary of the Invention

[0005] Therefore, it is necessary to provide a concrete temperature control circulation system and temperature control circulation method that can reduce energy consumption and improve temperature difference control efficiency to address the above problems.

[0006] A concrete temperature control circulation system includes a water storage component, a return water control valve, a drain tank, a refrigeration device, and a refrigeration control valve. The water storage component has a water storage chamber and is provided with a drain hole and a water inlet hole communicating with the water storage chamber. A water inlet pipe is connected to the drain hole, and the end of the water inlet pipe away from the water storage component is connected to a first connector of a cooling pipe assembly. The water storage component also has a return water hole communicating with the water storage chamber. The return water control valve is located at the return water hole. A drain pipe is connected to the drain tank, and the end of the drain pipe away from the drain tank is connected to a second connector of the cooling pipe assembly. The drain tank also has an outlet hole, which is connected to a circulation pipe assembly. The circulation pipe assembly has a first circulation channel and a second circulation channel. The first circulation channel connects the outlet hole and the return water hole. The second circulation channel connects to the refrigeration device, and the refrigeration outlet of the refrigeration device is connected to the return water hole.

[0007] In one embodiment, the return water control valve is a three-way control valve, and the circulation pipe group includes a main circulation pipe and two branch circulation pipes.

[0009] In one embodiment, the concrete temperature control circulation system further includes a heater disposed within the water storage chamber, the heater being used to heat the water within the water storage chamber.

[0010] In one embodiment, the concrete temperature control circulation system further includes a first thermometer, a second thermometer, and a temperature control module. The first thermometer is used to detect the outlet water temperature from the water storage chamber, and the second thermometer is used to detect the temperature of the concrete. The first thermometer, the second thermometer, the heater, and the refrigeration equipment are all electrically connected to the temperature control module. The temperature control module is used to control the operation of the heater and the refrigeration equipment based on the monitoring results of the first thermometer and the second thermometer.

[0011] In one embodiment, the concrete temperature control circulation system further includes a third thermometer for detecting the temperature of the cooling medium in the drainage tank, and the temperature control module for controlling the return water control valve and the refrigeration control valve based on the monitoring results of the third thermometer and the second thermometer.

[0012] In one embodiment, the concrete temperature control circulation system further includes a first water distributor, a second water distributor, and multiple cooling pipe groups. The multiple cooling pipe groups are laid in at least two layers in the concrete, with the cooling pipe groups in different layers spaced vertically. The first joint of the cooling pipe groups in different layers is connected to the water inlet pipe through the first water distributor, and the second joint of the cooling pipe groups in different layers is connected to the drain pipe through the second water distributor. Each layer of cooling pipe group is equipped with a water inlet control valve.

[0013] In one embodiment, the water storage assembly includes a water storage tank, a partition, and a switch unit. The water storage tank is hollow, and the partition is disposed in the water storage tank and divides the space inside the water storage tank to form the water storage cavity and the water inlet. The water inlet is connected to the water storage cavity, and the partition has a connecting hole. The switch unit is operably covered on the connecting hole, and the size of the connecting hole is larger than the size of the water inlet.

[0014] In one embodiment, the water storage chamber is located above the water reservoir. The switching unit includes a floating plug and a guide. The floating plug is located inside the water reservoir. The guide is connected to the floating plug. A mating part is provided inside the water reservoir. The guide and the mating part are guided and mated. The floating plug can float inside the water reservoir and can be inserted into the communicating hole.

[0015] In one embodiment, the upper surface of the floating plug is a spherical cap, and the upper surface of the floating plug can abut against the inner wall of the connecting hole.

[0016] In one embodiment, the mating part is a strip-shaped groove formed on the inner wall of the water storage cavity, the length direction of the strip-shaped groove is vertical, the guide part is a column structure, the guide part passes through the strip-shaped groove, and can slide within the strip-shaped groove.

[0017] In one embodiment, the number of guide portions is at least two, the number of mating portions is the same as the number of guide portions, each guide portion corresponds to a mating portion for guiding and mating, and each mating portion is arranged circumferentially along the inner wall of the water storage cavity.

[0018] A temperature control circulation method is provided for controlling a concrete temperature control circulation system as described above, characterized in that the temperature control circulation method includes:

[0019] Get the current drainage temperature of the water in the drainage tank;

[0020] If the current drainage temperature is less than or equal to the current room temperature water temperature, the refrigeration control valve is controlled to open the second circulation channel so that the water in the drainage tank enters the water storage chamber of the water storage component through the refrigeration equipment, and the water pump is controlled to pump the water in the water storage chamber to the cooling pipe group.

[0021] If the current drainage temperature is greater than the current ambient temperature water temperature, the refrigeration control valve is controlled to close the second circulation channel, the ambient temperature water is controlled to enter the water storage chamber of the water storage component through the refrigeration equipment, and the water pump is controlled to pump the water in the water storage chamber to the cooling pipe group.

[0022] Obtain the current concrete temperature and the current inlet water temperature of the water storage chamber;

[0023] Determine whether the temperature difference between the current concrete temperature and the current inlet water temperature is greater than the safe temperature difference threshold.

[0024] If so, the refrigeration equipment is controlled to stop operating, and room temperature water and / or water in the drain tank are controlled to be transported into the water storage chamber so that the temperature difference between the current concrete temperature and the current inlet water temperature is less than or equal to the safe temperature difference threshold.

[0025] In one embodiment, the temperature control cycle control method further includes:

[0026] The current inlet water temperature range is obtained based on the current concrete temperature and the safe temperature difference threshold.

[0027] If the current drainage temperature is within or below the current inlet water temperature range, the water in the drainage tank is controlled to be transported to the water storage chamber.

[0028] The above-mentioned concrete temperature control circulation system and temperature control circulation method have at least the following advantages over existing technologies:

[0029] The system obtains the current drainage temperature of the water in the drainage tank. If the current drainage temperature is less than or equal to the ambient water temperature, the refrigeration control valve opens the second circulation channel, allowing water from the drainage tank to pass through the refrigeration equipment into the water storage chamber of the storage component. The water in the storage chamber is then pumped to the cooling pipe assembly. If the current drainage temperature is greater than the ambient water temperature, the refrigeration control valve closes the second circulation channel, allowing ambient water to pass through the refrigeration equipment into the water storage chamber. The water in the storage chamber is then pumped to the cooling pipe assembly. In the initial stage of concrete pouring, when the internal temperature of the concrete is not yet high, the refrigeration equipment can be used to quickly cool the cooling water, achieving rapid cooling. When the drainage temperature is lower than the ambient water temperature, water from the drainage tank can be recovered, reducing the refrigeration energy consumption of the refrigeration equipment or improving the refrigeration effect.

[0030] The system continues to acquire the current concrete temperature and the current inlet water temperature of the storage chamber, determining whether the temperature difference between the two temperatures exceeds the safe temperature difference threshold. If so, the cooling equipment is stopped, and room temperature water and / or water from the drain tank are directed to the storage chamber to ensure the temperature difference is less than or equal to the safe temperature difference threshold. As construction progresses, the concrete temperature gradually rises. If the temperature difference between the cooling pipe assembly and the concrete is too large, it can cause cracking of the concrete. Therefore, if the temperature difference between the current concrete temperature and the current inlet water temperature exceeds the safe temperature difference threshold, there is no need to cool the circulating cooling water. Furthermore, by controlling the flow of some or all of the water from the drain tank to the storage chamber, the heat from the discharged circulating cooling water can be easily recovered, maintaining the temperature difference between the current inlet water temperature and the current concrete temperature. Through the arrangement and connection of the components and pipes within the concrete temperature control circulation system, the energy consumption of the cooling equipment can be reduced, energy recovery efficiency can be improved, and the efficiency of temperature difference control can be enhanced.

Detailed Implementation

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] See Figures 1 to 3The concrete temperature control circulation system 10 in one embodiment of this application can at least reduce energy consumption and improve temperature difference control efficiency. Specifically, the concrete temperature control circulation system 10 includes a water storage component 100, a return water control valve 200, a drain tank 300, a refrigeration device 400, and a refrigeration control valve 500. A water storage chamber 110 is formed inside the water storage component 100. The water storage component 100 has a drain hole 120 and a water inlet hole 130 communicating with the water storage chamber 110. A water inlet pipe 600 is connected to the drain hole 120. The end of the water inlet pipe 600 away from the water storage component 100 is used to connect with the first connector 202 of the cooling pipe assembly 20. The water storage component 100 also has a return water hole 140 communicating with the water storage chamber 110. A return water control valve 200 is located at the return water hole 140; a drain pipe 700 is connected to the drain tank 300, and the end of the drain pipe 700 away from the drain tank 300 is used to connect with the second connector 204 of the cooling pipe assembly 20. The drain tank 300 is also provided with a water outlet 310, and a circulation pipe assembly 320 is connected to the water outlet 310. A first circulation channel and a second circulation channel are formed in the circulation pipe assembly 320. The first circulation channel connects the water outlet 310 and the return water hole 140; the second circulation channel connects to the refrigeration equipment 400, and the refrigeration outlet of the refrigeration equipment 400 is connected to the return water hole 140; a refrigeration control valve 500 is used to control the opening and closing of the second circulation channel.

[0046] During operation, the current drainage temperature of the water in the drainage tank 300 is obtained. If the current drainage temperature is less than or equal to the ambient water temperature, the refrigeration control valve 500 is controlled to open the second circulation channel, allowing the water in the drainage tank 300 to pass through the refrigeration equipment 400 into the water storage chamber 110 of the water storage component 100, and the water in the water storage chamber 110 is pumped to the cooling pipe assembly 20. If the current drainage temperature is greater than the ambient water temperature, the refrigeration control valve 500 is controlled to close the second circulation channel, allowing the ambient water to pass through the refrigeration equipment 400 into the water storage chamber 110, and the water in the water storage chamber 110 is pumped to the cooling pipe assembly 20. In the early stages of concrete pouring, when the internal temperature of the concrete is not yet high, the refrigeration equipment 400 can be used to quickly cool the cooling water, achieving rapid cooling. When the drainage temperature is lower than the ambient water temperature, the water in the drainage tank 300 can be recovered, reducing the refrigeration energy consumption of the refrigeration equipment 400 or improving the refrigeration effect.

[0047] The system continues to acquire the current concrete temperature and the current inlet water temperature of the water storage chamber 110. If the temperature difference between the current concrete temperature and the current inlet water temperature exceeds the safe temperature difference threshold, the cooling equipment 400 is stopped, and room temperature water and / or water from the drain tank 300 are directed to the water storage chamber 110 to ensure that the temperature difference between the current concrete temperature and the current inlet water temperature is less than or equal to the safe temperature difference threshold. As construction progresses, the concrete temperature gradually increases. If the temperature difference between the cooling pipe assembly 20 and the concrete temperature is too large, it can cause cracking of the concrete. Therefore, since the temperature difference between the current concrete temperature and the current inlet water temperature exceeds the safe temperature difference threshold, there is no need to further cool the circulating cooling water. Furthermore, by controlling the flow of some or all of the water from the drain tank 300 to the water storage chamber 110, it is easy to recover the heat from the discharged circulating cooling water and maintain the temperature difference between the current inlet water temperature and the current concrete temperature. By arranging and connecting the various components and pipes within the concrete temperature control circulation system 10, it is possible to reduce the energy consumption of the refrigeration equipment 400, improve the energy recovery and utilization efficiency, and enhance the efficiency of temperature difference control.

[0048] In one embodiment, the return water control valve 200 is a three-way control valve. The circulation pipe group 320 includes a circulation main pipe 321 and two circulation branch pipes 322. One end of the circulation main pipe 321 is connected to the outlet hole 310, and the other end is connected to the two circulation branch pipes 322. One end of one circulation branch pipe 322 away from the circulation main pipe 321 is connected to the refrigeration equipment 400. The other end of the circulation branch pipe 322 away from the circulation main pipe 321 is connected to a pair of interfaces of the return water control valve 200. The other two interfaces of the return water control valve 200 are respectively connected to the return water hole 140 and the refrigeration outlet of the refrigeration equipment 400. The return water control valve 200 is controlled to connect the circulation branch pipe 322 to the return water hole 140 or to connect the refrigeration equipment 400 to the return water hole 140. By setting the return water control valve 200 as a three-way control valve, it is possible to effectively connect the water storage component 100, the drain tank 300 and the refrigeration equipment 400. It is also possible to selectively control the connection between the drain tank 300 and the water storage chamber 110 of the water storage component 100 or to control the connection between the water storage chamber 110 and the refrigeration equipment 400, thereby achieving the adjustment of the two circulation states of the system.

[0049] In other embodiments, the return water control valve 200 may also have other types of valve body structures, as long as it can selectively connect the drain tank 300 to the water storage chamber 110 of the water storage component 100 or control the water storage chamber 110 to be directly connected to the refrigeration equipment 400.

[0050] In one embodiment, the water inlet of the refrigeration equipment 400 is also connected to an external water inlet pipe 600, allowing external tap water or other cooling media to enter the refrigeration equipment 400 for cooling. At this time, the water passing through the concrete is discharged into the drain tank 300, realizing external circulation control for cooling and improving cooling efficiency.

[0051] In one embodiment, the refrigeration control valve 500 is a three-way control valve. The main circulation pipe 321 and the two circulation branch pipes 322 are respectively connected to three ports of the refrigeration control valve 500. The refrigeration control valve 500 is controlled to selectively connect one of the circulation branch pipes 322 to the main circulation pipe 321. By setting the refrigeration control valve 500 as a three-way control valve, it is convenient to connect the main circulation pipe 321 to the two circulation branch pipes 322, and it is also convenient to connect the main circulation pipe 321 to one of the circulation branch pipes 322. In other embodiments, the refrigeration control valve 500 can be located at the connection between the refrigeration equipment 400 and the circulation branch pipe 322, or on the circulation branch pipe 322 connected to the refrigeration equipment 400, for controlling the on / off connection between the refrigeration equipment 400 and the drain tank 300.

[0052] In this embodiment, the concrete temperature control circulation system 10 also includes a heater 800, which is disposed inside the water storage chamber 110. The heater 800 is used to heat the water in the water storage chamber 110. When the concrete is poured to the middle and later stages, the internal temperature of the concrete is high. In order to avoid an excessive temperature difference between the cooling pipe and the concrete, the water entering the concrete needs to be heated to control the temperature difference. After the heater 800 is turned on, all the water in the drainage tank 300 can be controlled to be transported to the water storage chamber 110, thereby reducing or even avoiding the addition of new water resources, and at the same time, the heat of the drained water can be effectively recovered, reducing energy consumption.

[0053] In one embodiment, the concrete temperature control circulation system 10 further includes a first thermometer, a second thermometer, and a temperature control module. The first thermometer is used to detect the outlet temperature of water from the water storage chamber 110, and the second thermometer is used to detect the temperature of the concrete. The first thermometer, the second thermometer, the heater 800, and the cooling device 400 are all electrically connected to the temperature control module. The temperature control module is used to control the operation of the heater 800 and the cooling device 400 based on the monitoring results of the first and second thermometers. The current concrete temperature can be obtained through the second thermometer. In order to control the temperature difference between the cooling pipe assembly 20 and the concrete temperature to be no greater than the safe temperature difference threshold, the operation of the heater 800 or the cooling device 400 can be controlled based on the detection result of the second thermometer to control the data detected by the first thermometer and ensure the cooling effect on the concrete.

[0054] In this embodiment, the concrete temperature control circulation system 10 also includes a third thermometer, which is used to detect the temperature of the cooling medium in the drainage tank 300. The temperature control module is used to control the return water control valve 200 and the cooling control valve 500 based on the monitoring results of the third thermometer. By detecting the temperature in the drainage tank 300 through the third thermometer, it is easy to determine whether to recycle the water in the drainage tank 300. For example, when the temperature in the drainage tank 300 is lower than the ambient temperature, the water in the drainage tank 300 is controlled to enter the cooling equipment 400. When the cooling equipment 400 is turned off, the proportion of water in the drainage tank 300 delivered to the water storage chamber 110 is adjusted according to the water temperature in the drainage tank 300 and the ambient water temperature to achieve a suitable outlet water temperature. When the required inlet water temperature entering the cooling pipe assembly 20 is higher than the water temperature in the drainage tank 300, all the water in the drainage tank 300 can be controlled to be delivered to the water storage chamber 110, and the heater 800 can be activated for heating. Specifically, a flow meter is installed on the pipe connecting the drain tank 300 and the water storage chamber 110, and a flow meter is installed at the water inlet 130 of the water storage component 100.

[0055] In one embodiment, the concrete temperature control circulation system 10 further includes a return water pipe 210, one end of which is connected to the return water hole 140, and the other end is connected to the return water control valve 200.

[0056] In one embodiment, the concrete temperature control circulation system 10 further includes a water pump 610, which is installed on the water inlet pipe 600 and is used to provide power to the cooling medium from the water storage chamber 110 to the water inlet pipe 600.

[0057] See Figure 1 and Figure 4 In one embodiment, the concrete temperature control circulation system 10 further includes a first water distributor, a second water distributor, and multiple cooling pipe assemblies 20. The multiple cooling pipe assemblies 20 are laid in at least two layers within the concrete, with vertical spacing between the different layers. The first connectors 202 of the cooling pipe assemblies 20 in different layers are connected to an inlet pipe 600 via the first water distributor, and the second connectors 204 of the cooling pipe assemblies 20 in different layers are connected to a drain pipe 700 via the second water distributor. Each layer of cooling pipe assemblies 20 is equipped with an inlet control valve. Because the concrete pouring has a certain thickness, setting at least two layers of cooling pipe assemblies 20 can improve the cooling effect on the concrete.

[0058] For example, in this embodiment, the concrete temperature control circulation system 10 is used in the construction of the foundation. A section of the foundation is equipped with three layers of cooling pipe groups 20, and each layer of cooling pipe group 20 is controlled by a water inlet control valve to control whether it is open or closed.

[0059] See Figure 3 , Figure 5 and Figure 6 In one embodiment, the water storage assembly 100 includes a water storage tank 150, a partition 160, and a switch unit 170. The water storage tank 150 is hollow. The partition 160 is disposed inside the water storage tank 150 and divides the space inside the water storage tank 150 to form a water storage cavity 110 and a water storage cavity 152. The water inlet 130 communicates with the water storage cavity 152. A connecting hole 162 is provided on the partition 160. The switch unit 170 is operably covered on the connecting hole 162, and the size of the connecting hole 162 is larger than the size of the water inlet 130. Since the cooling pipe assembly 20 is provided with at least two layers, when the other layer of the cooling pipe assembly 20 is activated, the water supply flow rate suddenly increases. The water storage capacity in the water storage cavity 110 is limited, which leads to a rapid decrease in the water level in the water storage cavity 110. Therefore, some water can be stored in the water storage chamber 152 in advance. Since the size of the connecting hole 162 is larger than the size of the inlet hole 130, when the water in the water storage chamber 110 decreases rapidly, the water in the water storage chamber 152 can be quickly replenished into the water storage chamber 110 through the connecting hole 162 to meet the suddenly increased flow requirements.

[0060] In this embodiment, the water storage chamber 152 is located above the water storage chamber 110. When the water in the water storage chamber 110 decreases, the water in the water storage chamber 152 can automatically replenish the water storage chamber 110 through the connecting hole 162 under its own weight. Specifically, the space of the water storage chamber 152 is smaller than the space of the water storage chamber 110, and the depth of the water storage chamber 152 is smaller than the depth of the water storage chamber 110, so as to avoid the water tank 150 being too large while meeting the requirements of rapid water replenishment.

[0061] In one embodiment, the switching unit 170 includes a floating plug 172 and a guide portion 174. The floating plug 172 is located inside the water storage chamber 110, and the guide portion 174 is connected to the floating plug 172. A mating portion 112 is provided inside the water storage chamber 110. The guide portion 174 and the mating portion 112 are guided and mated along the direction from the water storage chamber 110 to the water reservoir 152. The floating plug 172 can float inside the water storage chamber 110 and can be inserted into the connecting hole 162. When the water storage chamber 110 is relatively full, under the guidance and mating of the guide portion 174 and the mating portion 112 and the buoyancy of the floating plug 172, the floating plug 172 floats up and can be inserted into the connecting hole 162, separating the water reservoir 152 from the water storage chamber 110. When the water level in the water storage chamber 110 drops, the buoyancy of the floating plug 172 decreases, and the floating plug 172 disengages from the connecting hole 162, so that the water storage chamber 152 is connected to the water storage chamber 110, which facilitates the rapid replenishment of water in the water storage chamber 152 into the water storage chamber 110.

[0062] See Figures 5 to 7In one embodiment, the upper surface of the floating plug 172 is a spherical cap, which can abut against the inner wall of the connecting hole 162. Specifically, the shape of the inner wall of the connecting hole 162 is adapted to the upper surface of the floating plug 172, and the spherical cap allows the floating plug 172 to abut against the inner wall of the connecting hole 162 more reliably under the action of buoyancy.

[0063] In one embodiment, the number of guide portions 174 is at least two, and the number of mating portions 112 is the same as the number of guide portions 174. Each guide portion 174 corresponds to a mating portion 112 for guiding and mating. The mating portions 112 are arranged at intervals along the circumferential direction of the inner wall of the water storage cavity 110. By providing at least two guide portions 174, the stability of the floating plug 172 in floating is improved, so that the floating plug 172 can be stably inserted into the connecting hole 162.

[0064] In one embodiment, the mating part 112 is a strip-shaped groove formed on the inner wall of the water storage cavity 110, with the length direction of the strip-shaped groove being vertical. The guide part 174 is a cylindrical structure that passes through the strip-shaped groove and can slide within it. In other embodiments, the mating part 112 can also be a ring-shaped structure, with the guide part 174 passing through it. Of course, the guide part 174 and the mating part 112 can also have other structures that can achieve guiding engagement.

[0065] See Figure 1 and Figure 8 In one embodiment, the concrete temperature control circulation system 10 further includes a uniform cooling module 900. Water is introduced into the concrete through the uniform cooling module 900 from the water storage component 100. After passing through the concrete, the cooling water is discharged into the drainage tank 300 after passing through the uniform cooling module 900. By setting the uniform cooling module 900, the uniformity of concrete cooling can be improved, and excessive local temperature differences can be reduced or avoided.

[0066] Specifically, the balanced cooling module 900 includes a first water outlet pipe group 910, a second water outlet pipe group 920, a first control valve 930, a drain pipe 940, and a second control valve 950. The first water outlet pipe group 910 includes a first main water outlet pipe 912 and at least two first water outlet branch pipes 914. One end of each first water outlet branch pipe 914 is connected to the first main water outlet pipe 912, and the other end is connected to the first connector 202 of each cooling pipe group 20. The second water outlet pipe group 920 includes a second main water outlet pipe 922 and at least two second water outlet branch pipes 924. One end of each second water outlet branch pipe 924 is connected to the second main water outlet pipe 922, and the other end is connected to the second connector 204 of each cooling pipe group 20. The end of the first main water outlet pipe 912 furthest from the first water outlet branch pipe 914 and the end of the second main water outlet pipe 922 furthest from the second water outlet branch pipe 924 are both connected to the first control valve 930. The first control valve 930 is used to control the flow of cooling medium from the water storage chamber 110 of the water storage assembly 100 into the first main water outlet pipe 912 or into the second main water outlet pipe 922. One end of the drain pipe 940 is connected to the first water outlet pipe group 910. The end of the drain pipe 700 furthest from the drain tank 300 is connected to the second water outlet pipe group 920 through the second control valve 950. The other end of the drain pipe 940 is connected to the second control valve 950. The second control valve 950 is used to control the connection between the second water outlet pipe group 920 and the drain pipe 700 or to control the connection between the drain pipe 940 and the drain pipe 700.

[0067] During use, a first temperature is obtained in the area near the first connector 202 of the cooling pipe assembly 20, and a second temperature is obtained in the area near the second connector 204 of the cooling pipe assembly 20. The first and second temperatures are compared. If the first temperature is greater than the second temperature, the second control valve 950 is controlled to connect the second outlet pipe assembly 920 and the drain pipe 700, and the first control valve 930 is controlled to connect the first main outlet pipe 912. This allows the cooling medium to flow into the cooling pipe assembly 20 through the first main outlet pipe 912 and the first outlet branch pipe 914, and then through the first connector 202. The medium then flows out through the second outlet pipe assembly 920 and the second control valve 950 through the drain pipe 700. At this time, the water discharged through the water storage chamber 110 first flows into the cooling pipe assembly 20 through the first outlet pipe assembly 910 and the first connector 202, thus lowering the temperature near the first connector 202. If the first temperature is lower than the second temperature, the second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700, and the first control valve 930 is controlled to connect the second main outlet pipe 922, so that the cooling medium flows into the cooling pipe assembly 20 through the second main outlet pipe 922 and the second outlet branch pipe 924 and the second connector 204, and is discharged through the drain pipe 700 through the first outlet pipe assembly 910 and the drain pipe 940. At this time, the water drained from the water storage chamber 110 first enters the cooling pipe assembly 20 through the second outlet pipe assembly 920 and the second connector 204, reducing the stability near the second connector 204. When switching water flow modes, the above-mentioned balanced cooling module 900 only needs to control the first control valve 930 and the second control valve 950, while keeping the water storage chamber 110 always discharging water and the drain tank 300 always receiving the discharged water. This does not change the temperature control mode of the refrigeration equipment 400 or the heater 800 for the circulating water, nor does it change the connection control relationship between the water storage component 100, the drain, and the refrigeration equipment 400.

[0068] In this embodiment, the cooling pipe assembly 20 is provided with multiple layers. Each layer of the cooling pipe assembly 20 can be provided with a balanced cooling module 900, or only one balanced cooling module 900 can be provided, or two or more layers can be provided with a balanced cooling module 900.

[0069] In one embodiment, the first control valve 930 is a three-way control valve. The end of the inlet pipe 600 away from the water storage component 100, the first main outlet pipe 912, and the second main outlet pipe 922 are respectively connected to the three ports of the first control valve 930. By setting the first control valve 930 as a three-way control valve, it is convenient to control whether the inlet pipe 600 is connected to the first main outlet pipe 912 or the second main outlet pipe 922, thereby facilitating the control of the circulation direction of the cooling water.

[0070] Specifically, the equalization cooling module 900 also includes a first temperature sensor and a second temperature sensor. The first control valve 930, the first temperature sensor, and the second temperature sensor are all electrically connected to the temperature control module. The first temperature sensor is positioned near the first connector 202 on the cooling pipe assembly 20, and the second temperature sensor is positioned near the second connector 204 on the cooling pipe assembly 20. The temperature control module collects temperature data from the first and second temperature sensors and, based on the collected data, controls the first control valve 930 to connect the inlet pipe 600 to the first main outlet pipe 912 or to the second main outlet pipe 922. The first temperature sensor facilitates the detection of the temperature near the first connector 202, and the second temperature sensor facilitates the detection of the temperature near the second connector 204, thereby facilitating the control of the first control valve 930.

[0071] In this embodiment, the first joints 202 of each cooling pipe assembly 20 are close to each other and located in the middle or near the middle of the concrete to be tested. The second joints 204 of each cooling pipe assembly 20 are located near the edge of the concrete to be tested. A first temperature sensor is installed in the middle or near the middle of the concrete to be tested, and a second temperature sensor is installed near the edge of the concrete to be tested. Furthermore, at least two different temperature control zones are formed within the concrete to be tested. At least one cooling pipe assembly 20 is arranged in each temperature control zone, and a zone temperature sensor is installed in each temperature control zone.

[0072] In one embodiment, the equalization cooling module 900 further includes a proportional distribution valve 960, through which each of the first water outlet branch pipes 914 is connected to the first main water outlet pipe 912. The equalization cooling module 900 also includes at least two first water temperature sensors and at least two second water temperature sensors. Each first water temperature sensor is used to detect the temperature of the cooling medium at the first connector 202 of the cooling pipe assembly 20, and each second water temperature sensor is used to detect the temperature of the cooling medium at the second connector 204 of the cooling pipe assembly 20. The temperature control module is used to collect temperature data from the first water temperature sensors and each of the second water temperature sensors, and to control the proportional distribution valve 960 to adjust the flow rate of each of the first water outlet branch pipes 914 based on the collected data. In this embodiment, the first water temperature sensor can be the first temperature sensor described in the above embodiment, and the second water temperature sensor can be the second temperature sensor described in the above embodiment.

[0073] The first and second water temperature sensors can acquire the temperature difference between the outlet and inlet water temperatures of different cooling pipe groups 20, identifying cooling pipe groups 20 with temperature differences greater than or equal to a preset value and those with temperature differences less than a preset value. For example, when comparing two cooling pipe groups 20, the flow rate of the cooling pipe group 20 with the smaller temperature difference is adjusted to reduce the temperature difference, while the flow rate of the cooling pipe group 20 with the larger temperature difference is increased, thereby improving the temperature uniformity within the concrete. For instance, if the temperature difference between the outlet and inlet water of the two cooling pipe groups 20 is greater than 10°C and the temperature difference is uneven, the distribution ratio of the water entering from both sides is controlled to reduce the temperature difference and improve temperature uniformity.

[0074] In another embodiment, at least two distinct temperature-controlled zones are formed within the concrete to be tested. Each temperature-controlled zone is equipped with at least one cooling pipe assembly 20, and each zone is also equipped with a zone temperature sensor. Each zone temperature sensor is electrically connected to the temperature control module, which collects the temperature from each sensor and controls the proportional distribution valve to adjust the flow rate of each of the first outlet branch pipes 914 based on the collected data. By detecting the temperature of each temperature-controlled zone, if the temperature difference between the zones is large, it indicates uneven cooling within the concrete. In this case, the flow rate of the cooling pipe assembly 20 in the higher-temperature zone can be increased to improve heat exchange efficiency, while the flow rate in the lower-temperature zone can be decreased.

[0075] In one embodiment, the second control valve 950 is a three-way control valve. The second main outlet pipe 922, the drain pipe 940, and the drain pipe 700 are respectively connected to the three ports of the second control valve 950. The second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700 or the second main outlet pipe 922 and the drain pipe 700. The connection position of the second outlet branch pipe 924 and the second main outlet pipe 922 is located between the first control valve 930 and the second control valve 950. By setting the second control valve 950 as a three-way control valve, it is convenient to control the opening and closing of the drain pipe 940, thereby enabling the drainage to be effectively discharged through the drain pipe 700.

[0076] In the above embodiments, during the process of adjusting the flow direction of the cooling medium to regulate the uniformity of concrete cooling, it is necessary to control the temperature difference between the inlet water temperature of the cooling medium and the maximum temperature of the concrete within a safe temperature difference threshold. For example, the safe temperature difference threshold can be 25°C or 20°C to avoid excessive temperature difference between the inlet water temperature and the maximum temperature of the concrete, which could cause cracking of the concrete.

[0077] See Figures 1 to 4In one embodiment, this application also discloses a temperature control circulation method, which is used to control the concrete temperature control circulation system 10 in any of the above embodiments. Specifically, the temperature control circulation method includes:

[0078] Obtain the current drainage temperature of the water in the drainage tank 300;

[0079] If the current drainage temperature is less than or equal to the current room temperature water temperature, the refrigeration control valve 500 is controlled to open the second circulation channel so that the water in the drainage tank 300 enters the water storage chamber 110 of the water storage component 100 through the refrigeration equipment 400, and the water pump 610 is controlled to send the water in the water storage chamber 110 to the cooling pipe group 20.

[0080] If the current drainage temperature is greater than the current ambient temperature water temperature, then control the refrigeration control valve 500 to close the second circulation channel, control the ambient temperature water to enter the water storage chamber 110 of the water storage component 100 through the refrigeration equipment 400, and control the water pump 610 to send the water in the water storage chamber 110 to the cooling pipe group 20.

[0081] Obtain the current concrete temperature and the current inlet water temperature of the water storage chamber 110;

[0082] Determine whether the temperature difference between the current concrete temperature and the current inlet water temperature is greater than the safe temperature difference threshold.

[0083] If so, the refrigeration equipment 400 is stopped, and the room temperature water and / or the water in the drain tank 300 are transported to the water storage chamber 110 so that the temperature difference between the current concrete temperature and the current inlet water temperature is less than or equal to the safe temperature difference threshold.

[0084] In one embodiment, the temperature control cycle control method further includes:

[0085] The current inlet water temperature range is obtained based on the current concrete temperature and the safe temperature difference threshold.

[0086] If the current drainage temperature is within or below the current inlet water temperature range, the water in the drainage tank 300 is controlled to be transported to the water storage chamber 110.

[0087] In this embodiment, the temperature difference between the inlet water and the internal temperature of the concrete is set to 25°C during the heating period. That is, when the inlet water temperature and the maximum concrete temperature are within 25°C, the cooling equipment 400 continuously operates to reduce the inlet water temperature. When the inlet water temperature and the maximum concrete temperature are detected to be greater than 25°C, the cooling equipment 400 stops operating. Then, the heater 800 is started and the amount of water delivered from the drainage tank 300 to the water storage chamber 110 is controlled based on the temperature detection results. For example, the safe temperature difference threshold can also be 20°C.

[0088] In one embodiment, the temperature control cycle control method further includes:

[0089] Obtain a first temperature in the region near the first joint 202 of the cooling pipe assembly 20 and a second temperature in the region near the second joint 204 of the cooling pipe assembly 20;

[0090] Compare the first temperature and the second temperature;

[0091] If the first temperature is greater than the second temperature, then control the second control valve 950 to connect the second water outlet pipe group 920 and the drain pipe 700, and control the first control valve 930 to connect the first main water outlet pipe 912, so that the cooling medium flows into the cooling pipe group through the first main water outlet pipe 912 and the first water outlet branch pipe 914 and through the first connector 202, and is discharged through the drain pipe 700 through the second water outlet pipe group 920 and the second control valve 950;

[0092] If the first temperature is lower than the second temperature, the second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700, and the first control valve 730 is controlled to connect the second main outlet pipe 924, so that the cooling medium flows into the cooling pipe group 20 through the second main outlet pipe 922 and the second outlet branch pipe 924 and through the second connector 204, and is discharged through the drain pipe 700 through the first outlet pipe group 910 and the drain pipe 940.

[0093] In one embodiment, the temperature control cycle control method further includes:

[0094] Obtain the temperature difference between the outlet and inlet water temperatures of different cooling pipe assemblies 20;

[0095] Identify cooling pipe groups with a temperature difference greater than or equal to a preset difference and cooling pipe groups with a temperature difference less than a preset difference;

[0096] Adjust the flow rate of the cooling pipe group 20 with a small temperature difference to reduce the flow rate of the cooling pipe group 20 with a large temperature difference.

[0097] The aforementioned concrete temperature control circulation system 10 and temperature control circulation method can realize temperature monitoring of large-volume concrete, ensuring timely and effective adjustment of on-site temperature control measures. The measured maximum internal surface temperature difference of the concrete during the construction of the main pier foundation of the passageway is less than 20℃, effectively preventing the generation of temperature cracks, thereby improving concrete durability and ensuring the construction quality of large-volume concrete. The circulation control system intelligently and automatically regulates the flow rate of the foundation cooling pipe group 20, achieving automatic control of cooling water temperature and saving a significant amount of fresh water resources. With the rapid development of bridge construction technology, the widespread application of large-volume concrete in the construction industry has been promoted. This innovative construction technology enables temperature monitoring of large-volume concrete, and through dynamic adjustment of temperature control measures during the construction process, effectively prevents the generation of temperature cracks, thereby improving concrete durability.
