Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete technology, and in particular relates to a temperature control device for large-volume concrete. Background Technology
[0002] During the pouring of large-volume concrete, the cement hydration reaction releases a significant amount of heat. Due to concrete's poor thermal conductivity and its large volume, the accumulated heat is difficult to dissipate effectively, leading to a significant increase in the internal temperature of the concrete. This temperature rise creates a distinct temperature gradient between the interior of the concrete structure and the external environment, resulting in substantial temperature stress. When this temperature stress exceeds the tensile strength of the concrete, it can easily cause cracking, severely impacting the integrity and durability of the structure.
[0003] Currently, in engineering practice, the common method is to pre-embed fixed temperature sensors inside the concrete to monitor the internal temperature of large-volume concrete. Once the internal temperature exceeds a certain value, water mist is sprayed onto the concrete surface to cool it down. However, fixed temperature sensors not only fail to provide continuous spatial monitoring and comprehensive coverage of the entire large-volume concrete structure, but also cannot track the dynamic migration of temperature peaks during the cement hydration heat process in real time. This is especially problematic in critical areas such as stress concentration zones and abrupt changes in cross-section, where monitoring blind spots are likely to occur. This results in incomplete temperature monitoring data, making it difficult to detect localized high-temperature risk areas in a timely manner. This increases the probability of temperature cracks in large-volume concrete, posing a potential threat to the overall safety performance of the engineering structure. Furthermore, while water mist spraying can provide some cooling, it only lowers the surface temperature of the concrete and cannot effectively transfer heat to the interior, leaving the risk of not being able to effectively control the internal temperature of the concrete.
[0004] Therefore, there is an urgent need for a temperature control device for large-volume concrete to solve the above problems. Utility Model Content

The temperature measuring elements are used to measure the temperature inside a large volume of concrete. The first direction and the second direction are perpendicular to the vertical direction.
[0010] Several heat dissipation components, which can be detachably installed inside the cavity of any heat pipe, are configured to dissipate heat from the interior of a large volume of concrete.
[0011] The spray assembly is movably mounted on the top of the support in a vertical direction. The spray assembly is used to spray water onto the surface of large-volume concrete.
[0012] Optionally, the temperature measuring assembly also includes a first rotary drive and a first lead screw extending along a second direction. The movable seat is threadedly connected to the first lead screw, and the output end of the first rotary drive is connected to the first lead screw to drive the first lead screw to rotate about its axial direction.
[0013] Optionally, a limiter is provided at the end of the first lead screw, and the temperature measuring assembly also includes multiple sensors disposed on the movable seat. Sensors are disposed on both sides of the movable seat along the second direction. The sensors are electrically connected to the first rotary drive component, and the sensors can move with the movable seat to contact the limiter.
[0014] Optionally, the heat dissipation assembly includes a first connecting ring, a rotating shaft, and multiple heat dissipation blades. The first connecting ring is threadedly connected to the inner wall of the heat pipe. The rotating shaft is rotatably disposed on the first connecting ring about a second direction. The multiple heat dissipation blades are spaced apart on the rotating shaft along the circumference of the rotating shaft.
[0015] Alternatively, the heat dissipation component may include a water pipe that passes through a heat pipe.
[0016] Optionally, the spray assembly includes a water storage component and multiple nozzles disposed on the water storage component. The water storage component is movably disposed on the top of the support in a vertical direction, and the multiple nozzles are arranged at intervals along the extension direction of the water storage component.
[0017] Optionally, the spray assembly also includes a second lead screw, one end of which is rotatably connected to the water storage component, and the other end is threadedly connected to the bracket.
[0018] Optionally, the inner cavity of the heat pipe on which the temperature measuring component is installed is provided with a mounting ring, and the temperature measuring component also includes a connecting frame extending in a second direction. The movable seat is movably disposed on the connecting frame in the second direction, and the connecting frame can be inserted into or detached from the inner hole of the mounting ring.
[0019] Optionally, the inner cavity of the heat pipe is provided with an annular support frame, the outer wall of the annular support frame is connected to the inner wall of the heat pipe, and the annular support frame is provided with multiple hollow positions, with the temperature measuring component located in the inner hole of the annular support frame.
[0020] Optionally, the heat pipe with heat dissipation components is equipped with a filter screen at its inlet, and the filter screen is detachably connected to the wall of the heat pipe.
[0021] Optionally, the heat pipe with the temperature sensing component is equipped with a sealing element at its inlet. The sealing element is detachably connected to the wall of the heat pipe and is sealed in place. The sealing element is used to seal the inlet of the heat pipe.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] This invention provides a temperature control device for large-volume concrete. Heat-conducting pipes are inserted into the large-volume concrete to facilitate heat dissipation. Temperature-measuring components are installed inside the heat-conducting pipes. Temperature sensors are installed on both sides of the movable base along the vertical direction, allowing the temperature of the large-volume concrete located above and below the heat-conducting pipes to be monitored. This expands the monitored range and effectively avoids blind spots in temperature monitoring. Furthermore, the movable base can move along a second direction, allowing the temperature of any part of the large-volume concrete along this direction to be monitored. This achieves dynamic monitoring of the internal temperature of the large-volume concrete, further reducing the range of blind spots and significantly lowering the probability of temperature cracks in the large-volume concrete. Multiple heat-conducting pipes are arranged along the first direction, and temperature-measuring components can be installed inside any of them. This allows workers to adapt the arrangement of heat-conducting pipes and temperature-measuring components according to the specifications of the large-volume concrete to be poured, ensuring that the temperature of all parts of the large-volume concrete along the first direction can be monitored. This ensures the integrity of temperature monitoring data, allows workers to promptly identify high-temperature risk areas inside the large-volume concrete, and improves the quality of the poured large-volume concrete. When the temperature sensor detects excessively high internal temperature in the large-volume concrete, workers can use heat dissipation and spraying components to cool it down. The heat dissipation components work in conjunction with the heat pipes to rapidly dissipate heat from within the concrete, while the spraying components cool it from the outside, significantly increasing the cooling rate and ensuring the safety of the large-volume concrete structure. Furthermore, the heat dissipation components can be installed on any heat pipe, allowing workers to proactively arrange their location and quantity based on the potential locations of high-temperature areas within the concrete to ensure effective heat dissipation. Additionally, the spraying components are vertically movable, making them suitable for cooling large-volume concrete at different heights, expanding the versatility of temperature control devices for large-volume concrete. Both the temperature sensor and heat dissipation components are detachably installed on the heat pipes. After the large-volume concrete is poured, the heat pipes remain inside, allowing the temperature sensor and heat dissipation components to be removed and reused, reducing construction costs.

They are only for the convenience of describing this 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 this utility model.
[0044] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" 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 this utility model based on the specific circumstances.
[0045] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0046] like Figures 1 to 10 As shown, this embodiment provides a temperature control device for large-volume concrete, which can dynamically monitor the internal temperature of large-volume concrete, avoid the occurrence of monitoring blind spots, reduce the probability of temperature cracks in large-volume concrete, improve the cooling rate of large-volume concrete, and ensure the safety of large-volume concrete structures.
[0047] See Figure 1 , Figure 2 and Figure 5 The temperature control device for large-volume concrete includes a support frame 1, several temperature measuring components 2, several heat dissipation components 3, and a spraying component 4. The support frame 1 is equipped with multiple spray nozzles along a first direction (…). Figure 1 Heat pipes 5 are arranged at intervals in the X direction, and the heat pipes 5 can move along the second direction ( Figure 1 The temperature measuring component 2 is installed in the large volume of concrete in the Y direction; the temperature measuring component 2 can be detachably installed in the inner cavity of any heat-conducting pipe 5. The temperature measuring component 2 includes a movable base 21 movable in the second direction and a plurality of temperature measuring elements 22 disposed on the movable base 21. The movable base 21 is in the vertical direction ( Figure 1Temperature measuring elements 22 are provided on both sides of the Z direction (in the middle), and the temperature measuring elements 22 are used to measure the temperature inside the large volume concrete. The first direction and the second direction are perpendicular to the vertical direction. The heat dissipation component 3 can be detachably installed in the inner cavity of any heat conduction pipe 5 and is configured to dissipate the heat inside the large volume concrete. The spray component 4 is movably installed on the top of the support 1 in the vertical direction and is used to spray water onto the surface of the large volume concrete.
[0048] The temperature control device for large-volume concrete provided in this embodiment has a heat-conducting pipe 5 inserted into the large-volume concrete, which helps to dissipate heat from within the concrete. A temperature measuring component 2 is installed inside the heat-conducting pipe 5. Temperature measuring elements 22 are provided on both sides of the movable base 21 along the vertical direction, allowing the temperature of the large-volume concrete located above and below the heat-conducting pipe 5 to be monitored. This expands the monitoring range of the large-volume concrete and effectively avoids the occurrence of temperature monitoring blind spots. Furthermore, the movable base 21 can move along a second direction, allowing the temperature of any part of the large-volume concrete along that second direction to be monitored. This achieves dynamic monitoring of the internal temperature of the large-volume concrete, further reducing the range of monitoring blind spots and significantly lowering the probability of temperature cracks in the large-volume concrete. Multiple heat-conducting pipes 5 are arranged along the first direction, and the temperature measuring component 2 can be installed inside any of the heat-conducting pipes 5. This allows workers to adapt the arrangement of the heat-conducting pipes 5 and the temperature measuring component 2 according to the specifications of the large-volume concrete to be poured, ensuring that the temperature of all parts of the large-volume concrete along the first direction can be monitored. This ensures the integrity of the temperature monitoring data and allows workers to promptly identify high-temperature risk areas inside the large-volume concrete, improving the quality of the poured concrete. When the temperature measuring component 22 detects that the internal temperature of the large-volume concrete is too high, workers can use the heat dissipation component 3 and the spray component 4 to cool the concrete. The heat dissipation component 3 works in conjunction with the heat-conducting pipes 5 to quickly dissipate heat from inside the large-volume concrete, while the spray component 4 cools the concrete from the outside, significantly increasing the cooling rate and ensuring the safety of the large-volume concrete structure. Furthermore, the fact that the heat dissipation component 3 can be installed on any of the heat-conducting pipes 5 allows workers to proactively arrange the position and number of heat dissipation components 3 according to the locations of areas prone to high temperatures inside the large-volume concrete, ensuring effective heat dissipation. Furthermore, the spray assembly 4 is vertically movable, making it suitable for cooling large-volume concrete at different heights, thus expanding the versatility of temperature control devices for large-volume concrete. Both the temperature measuring assembly 2 and the heat dissipation assembly 3 are detachably installed on the heat conduction pipe 5. After the large-volume concrete is poured, the heat conduction pipe 5 remains inside the concrete, allowing the temperature measuring assembly 2 and the heat dissipation assembly 3 to be removed and reused, reducing construction costs.
[0049] For example, the heat pipe 5 is made of copper. Copper has extremely high thermal conductivity, so under the same temperature difference, copper can transfer heat from the hot end to the cold end more quickly, that is, transfer the temperature inside the large volume concrete to the outside of the large volume concrete, significantly improving the heat dissipation efficiency of the large volume concrete. The temperature measuring element 22 is a temperature sensor, and only one temperature measuring element 22 is provided on each side of the moving base 21 along the vertical direction.
[0050] In this embodiment, see Figure 1 , Figure 2 and Figure 5 There are three heat pipes 5. All three heat pipes 5 are buried at the bottom of a large volume of concrete. Only heat dissipation components 3 are installed in the heat pipes at both ends, and only temperature measuring components 2 are installed in the heat pipe in the middle.
[0051] For example, see Figure 1 The cross-sectional shape of the support 1 is L-shaped, and the spray assembly 4 is set on the top of the L-shaped support 1.
[0052] Optionally, see Figure 2 , Figure 3 and Figure 4 The temperature measuring component 2 also includes a first rotary drive 23 and a first lead screw 24 extending along a second direction. A movable seat 21 is threadedly connected to the first lead screw 24. The output end of the first rotary drive 23 is connected to the first lead screw 24 to drive the first lead screw 24 to rotate around its axial direction. The first lead screw 24 drives the temperature measuring component 22 to move along the second direction via the movable seat 21. By changing the direction of rotation of the first lead screw 24, the movable seat 21 can reciprocate on the first lead screw 24, thereby achieving dynamic monitoring of the internal temperature of large-volume concrete.
[0053] For example, the first rotary drive 23 is a motor.
[0054] In this embodiment, see Figure 3 and Figure 4 The end of the first lead screw 24 is provided with a limiting member 25. The temperature measuring assembly 2 also includes a plurality of sensors 26 disposed on the movable seat 21. Sensors 26 are disposed on both sides of the movable seat 21 along the second direction. The sensors 26 are electrically connected to the first rotary drive member 23. The sensors 26 can move with the movable seat 21 to contact the limiting member 25. When the sensor 26 contacts the limiting member 25, it indicates that the movable seat 21 has moved to the end of the first lead screw 24. At this time, the first rotary drive member 23 controls the first lead screw 24 to rotate in the opposite direction, so that the movable seat 21 moves away from the contacted limiting member 25, ensuring that the movable seat 21 will not detach from the first lead screw 24 and can automatically reciprocate on the first lead screw 24.
[0055] For example, sensor 26 is a pressure sensor. When the pressure sensor comes into contact with the limiting member 25, the pressure sensor senses pressure, and the moving seat 21 moves to the limiting member 25. The limiting member 25 is a plate, and a first rotary drive member 23 is disposed on the limiting member 25. A first lead screw 24 rotatably passes through the limiting member 25 and is connected to the first rotary drive member 23.
[0056] In an optional embodiment, see [link to relevant documentation] Figure 5 , Figure 6 and Figure 7 The heat dissipation assembly 3 includes a first connecting ring 31, a rotating shaft 32, and multiple heat dissipation blades 33. The first connecting ring 31 is threadedly connected to the inner wall of the heat pipe 5. The rotating shaft 32 is rotatably mounted on the first connecting ring 31 in a second direction. The multiple heat dissipation blades 33 are spaced apart on the rotating shaft 32 circumferentially. The threaded connection between the first connecting ring 31 and the inner wall of the heat pipe 5 not only ensures the stability of the connection between the first connecting ring 31 and the inner wall of the heat pipe 5, but also allows the first connecting ring 31 to be detached from the heat pipe 5, thus achieving a detachable connection between the heat dissipation assembly 3 and the inner wall of the heat pipe 5. Driving the rotating shaft 32 to rotate causes the multiple heat dissipation blades 33 to rotate in the second direction, thereby accelerating the airflow inside the heat pipe 5 and around the heat pipe 5, allowing the heat inside the large volume of concrete to be quickly dissipated.
[0057] Specifically, see Figure 7 The first connecting ring 31 includes a first ring body 311 and a second ring body 312 connected together. The outer wall of the first ring body 311 is threadedly connected to the inner wall of the heat pipe 5. The second ring body 312 is located on the side of the first ring body 311 away from the heat pipe 5. The inner hole of the second ring body 312 is provided with a mounting plate 313 extending radially therefrom. The rotating shaft 32 is located in the inner hole of the second ring body 312 and is rotatably connected to the mounting plate 313 through a bearing.
[0058] For example, see Figure 6 In one embodiment, the heat dissipation component 3 is only provided at one end of the heat pipe 5; in other embodiments, the heat dissipation component 3 is provided at both ends of the heat pipe 5.
[0059] In this embodiment, the heat dissipation component 3 further includes a second rotation drive member disposed on the first connecting ring 31. The output end of the second rotation drive member is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate.
[0060] For example, the second rotary drive is a motor.
[0061] In another alternative embodiment, the heat dissipation component 3 is a fan.
[0062] In another optional embodiment, the heat dissipation assembly 3 includes a water pipe that passes through the heat-conducting pipe 5. When the temperature measuring element 22 measures that the concrete temperature is too high, cold water can be injected into the water pipe from one end. As the cold water flows along the axial direction of the heat-conducting pipe 5 and flows out of the heat-conducting pipe 5, it can carry away the heat inside the heat-conducting pipe 5, thereby cooling the large volume of concrete.
[0063] Optionally, see Figure 1 and Figure 2 The spray assembly 4 includes a water storage unit 41 and multiple nozzles 42 disposed on the water storage unit 41. The water storage unit 41 is movably disposed on the top of the support 1 in a vertical direction, and the multiple nozzles 42 are arranged at intervals along the extension direction of the water storage unit 41. When the temperature measuring element 22 detects that the temperature of the large-volume concrete is too high, the water in the water storage unit 41 can be evenly sprayed onto the large-volume concrete through the multiple nozzles 42 to cool the large-volume concrete. The arrangement of multiple nozzles 42 can expand the spraying range of the large-volume concrete and ensure the uniformity of spraying, so as to ensure the consistency of temperature change in various parts of the large-volume concrete and avoid temperature differences inside the large-volume concrete.
[0064] For example, see Figure 1 The water storage component 41 adopts a barrel with a cylindrical cross-section.
[0065] In this embodiment, see Figure 1 The spray assembly 4 also includes a second lead screw 43 extending vertically. One end of the second lead screw 43 is rotatably connected to the water storage component 41, and the other end is threadedly connected to the bracket 1. This configuration not only achieves the connection between the spray assembly 4 and the bracket 1, but also allows the height of the water storage component 41 on the bracket 1 to be adjusted to accommodate large volumes of concrete of different heights.
[0066] Specifically, see Figure 1 and Figure 8 The top of the bracket 1 is provided with a threaded groove 11, and the end of the second lead screw 43 away from the water storage component 41 is located in the threaded groove 11 and is threadedly connected to the groove wall of the threaded groove 11.
[0067] In this embodiment, see Figure 1 and Figure 9 The top of the support 1 is provided with a guide groove 12 extending vertically. A guide 44 is provided on the water storage component 41. The guide 44 is slidably disposed in the guide groove 12 along the extension direction of the guide groove 12. When the water storage component 41 moves vertically, the water storage component 41 drives the guide 44 to slide within the guide groove 12. When the height of the spray assembly 4 is changed, the guide 44 can only move vertically under the constraint of the guide groove 12, thereby effectively constraining the direction of movement of the water storage component 41 and ensuring that the water storage component 41 can only move vertically.
[0068] See Figure 1 The spray assembly 4 also includes a water supply pipe 45 connected to the water storage component 41. A flange 46 is provided at the end of the water supply pipe 45 away from the water storage component 41. The temperature control device for large-volume concrete also includes a water tank (not shown in the figure). The water supply pipe 45 can be quickly connected to the pipe on the water tank through the flange 46 to transport water in the water tank to the water storage component 41 through the water supply pipe 45.
[0069] Optionally, see Figure 2 , Figure 3 and Figure 4 The inner cavity of the heat pipe 5, on which the temperature measuring component 2 is installed, is provided with an installation ring 51. The temperature measuring component 2 also includes a connecting frame 27 extending in a second direction. A movable seat 21 is movably disposed on the connecting frame 27 in the second direction. The connecting frame 27 can be inserted into or detached from the inner hole of the installation ring 51. When the connecting frame 27 is inserted into the inner hole of the installation ring 51, the installation ring 51 can support the connecting frame 27 to fix the position of the connecting frame 27 in the inner cavity of the heat pipe 5, preventing the connecting frame 27 from shaking during the pouring of large volume concrete. After the large volume concrete is poured, the connecting frame 27 can be pulled out from the inner hole of the installation ring 51 and removed from the inner cavity of the heat pipe 5, so that the temperature measuring component 2 can be reused.
[0070] Specifically, see Figure 3 Both ends of the heat pipe 5 are provided with mounting rings 51, and the two ends of the connecting bracket 27 are respectively inserted into the inner holes of the two mounting rings 51.
[0071] For example, see Figure 2 The connecting frame 27 adopts a rectangular frame, and the cross-sectional shape of the inner hole of the mounting ring 51 is rectangular to prevent the connecting frame 27 from rotating inside the mounting ring 51; the limiting member 25, the first lead screw 24, the first rotation drive member 23, the moving seat 21, the sensor 26 and the temperature measuring member 22 are all located inside the rectangular frame.
[0072] Optionally, see Figure 2 , Figure 9 and Figure 10 The inner cavity of the heat-conducting pipe 5 is equipped with an annular support frame 6, the outer wall of which is connected to the inner wall of the heat-conducting pipe 5. The annular support frame 6 has multiple hollowed-out positions 61, and the temperature measuring component 2 is located within the inner hole of the annular support frame 6. The annular support frame 6 increases the wall thickness of the heat-conducting pipe 5, preventing deformation under the pressure of concrete and ensuring that the heat-conducting pipe 5 can firmly support the large volume of concrete, preventing local collapse or deformation and ensuring the quality of the large volume concrete pouring. The hollowed-out positions 61 not only reduce the production cost of the annular support frame 6 but also prevent it from affecting the temperature measuring accuracy of the temperature measuring component 22, ensuring that the temperature measuring component 22 can accurately measure the temperature of the large volume of concrete.
[0073] Specifically, see Figure 3 The length of the annular support frame 6 is less than the length of the heat pipe 5, and the mounting ring 51 is set at the end of the annular support frame 6 and fixedly connected to the annular support frame 6.
[0074] Optionally, see Figure 1 and Figure 6 The heat pipe 5, on which the heat dissipation component 3 is installed, has a filter screen 7 at its inlet. The filter screen 7 is detachably connected to the wall of the heat pipe 5. The filter screen 7 not only ensures that the heat inside the heat pipe 5 can be discharged from the inlet of the heat pipe 5 under the action of the heat dissipation component 3, but also prevents large dust or debris from entering the heat pipe 5 on which the heat dissipation component 3 is installed, prevents concrete from clogging the heat pipe 5, and ensures that the heat dissipation component 3 can operate normally.
[0075] Specifically, see Figure 6 and Figure 7 When the heat pipe 5 is provided with a heat dissipation component 3, the filter screen 7 is installed on the side of the second ring 312 away from the first ring 311; when the heat pipe 5 is not provided with a heat dissipation component 3, the heat pipe 5 is provided with a second connecting ring 52 threadedly connected to it, and the filter screen 7 is installed on the second connecting ring 52.
[0076] Optionally, see Figure 1 , Figure 3 and Figure 4 A sealing element 8 is installed at the opening of the heat pipe 5, which houses the temperature measuring component 2. The sealing element 8 is detachably connected to and seals against the wall of the heat pipe 5. The sealing element 8 seals the opening of the heat pipe 5 to prevent dust or debris from entering the inner cavity of the heat pipe 5, preventing concrete blockage and ensuring the proper functioning of the temperature measuring component 2 within the heat pipe 5. After the concrete pouring is completed, the sealing element 8 is removed from the heat pipe 5, opening the opening. Workers can then remove the entire temperature measuring component 2 from the heat pipe 5 by pulling out the connecting bracket 27, allowing for reuse. The sealing element 8's seal with the wall of the heat pipe 5 improves the sealing performance of the inner cavity, further effectively preventing dust or debris from entering the inner cavity of the heat pipe 5.
[0077] In this embodiment, see Figure 3 The sealing component 8 includes a sealing disc 81 and an operating part 82 disposed on the sealing disc 81. The sealing disc 81 is threadedly connected to the wall of the heat-conducting pipe 5. The operator can screw the sealing disc 81 through the operating part 82 to connect or disconnect the sealing disc 81 from the heat-conducting pipe 5. The threaded connection between the sealing disc 81 and the wall of the heat-conducting pipe 5 not only allows the sealing disc 81 to be detachably connected to the heat-conducting pipe 5, but also ensures the sealing performance after connection.
[0078] In other embodiments, the sealing component 8 includes a sealing disc 81, a sealing ring, and an operating part 82 disposed on the sealing disc 81. The sealing disc 81 is inserted into the heat-conducting pipe 5 and is sealed to the pipe wall of the heat-conducting pipe 5 through the sealing ring to ensure the sealing performance of the connection between the sealing disc 81 and the pipe wall of the heat-conducting pipe 5.
[0079] For example, the sealing ring is a rubber ring.
[0080] See Figure 4 When the sealing plate 81 is connected to the heat pipe 5, the sealing plate 81 can fit tightly against the end face of the connecting frame 27, and the sealing plate 81 can provide a certain support for the connecting frame 27.
[0081] Optionally, the temperature control device for large-volume concrete also includes a controller. The controller is electrically connected to the first rotary drive 23, the temperature measuring element 22, the sensor 26, and the second rotary drive. The controller is used to control the opening and closing of the first rotary drive 23 and the second rotary drive. When the temperature measured by the temperature measuring element 22 is too high, the controller can control the second rotary drive to open to dissipate heat from the concrete. When the sensor 26 contacts the limiting element 25, the controller can control the first rotary drive 23 to drive the first lead screw 24 to change its rotation direction, so that the moving seat 21 can reciprocate on the first lead screw 24.
[0082] In this embodiment, a water pump is installed in the water tank, and the water pump is electrically connected to the controller, which can control the start and stop of the water pump. When the temperature measured by the temperature measuring element 22 is too high, the controller can control the water pump to start in order to cool the concrete.
[0083] For example, the controller is a programmable logic controller.
[0084] The usage process of the temperature control device for large-volume concrete provided in this embodiment is as follows:
[0085] Place the bracket 1 together with the heat pipe 5 at the bottom of the large volume of concrete to be poured, and screw the second screw 43 until the water storage component 41 moves vertically to a suitable height, after which the concrete can be poured.
[0086] During the concrete pouring process, the controller activates the first rotary drive 23, which drives the first lead screw 24 to rotate. The moving seat 21 moves along the second direction, and the temperature measuring element 22 measures the temperature on the upper and lower sides of the moving element. When the sensor 26 moves with the moving seat 21 to contact the limiting element 25, the controller will change the rotation direction of the first lead screw 24 through the first rotary drive 23, and the moving direction of the moving seat 21 will change.
[0087] When the temperature measured by the temperature measuring element 22 is high, the controller will activate the second rotary drive element, and the rotating shaft 32 will drive the heat dissipation blades 33 to rotate, so as to cool the interior of the large volume concrete. At the same time, the controller will activate the water pump in the water tank. The water in the water tank will be sent to the water storage element 41 through the water pipe 45 under the power of the water pump. The water will be sprayed out from the water storage element 41 through the nozzle 42 to cool the surface of the large volume concrete.
[0088] After the concrete is poured and solidified, screw the second screw 43 to remove the spray assembly 4 from the bracket 1; screw the sealing plate 81 through the operating part 82 to remove the connecting bracket 27 from the inner hole of the mounting ring 51 and the inner cavity of the heat conduction pipe 5; screw the first connecting ring 31 to remove the heat dissipation assembly 3 from the guide tube; screw the second connecting ring 52 to remove the filter screen from the guide tube.
[0089] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
