Description

Technical Field

[0001] This invention relates to the field of temperature control technology in concrete construction, specifically a temperature control device and method for large-volume concrete. Background Technology

[0002] Large-volume concrete pylon caps are key load-bearing components in bridge structures, located at the base of the pylon and connecting the pile foundations and the pylon column. Their primary function is to evenly distribute the enormous loads (such as self-weight, wind loads, and vehicle loads) transmitted from the upper pylon and bridge deck to the pile foundation group below, ultimately transferring them to the foundation soil to ensure the overall stability of the bridge. However, large-volume concrete generates a significant amount of heat during its solidification process, and internal heat dissipation is difficult, resulting in a significant temperature difference between the inside and outside, inducing thermal stress. When this stress exceeds the tensile strength of the concrete, thermal cracks will occur, affecting the structural durability and safety. Temperature control is necessary, typically achieved by internal cooling water circulation or continuous external watering to maintain the temperature of the large-volume concrete.

[0003] However, the concrete foundation is located at a high position, and when water is poured to cool it down, the higher parts of the foundation are not easily sprayed. The temperature on the outside of the foundation changes constantly, making it difficult to accurately adjust the spraying position according to the temperature difference. This can easily lead to uneven temperature in different parts of the concrete foundation, affecting solidification and molding. Furthermore, when the temperature difference between the foundation and the sprayed water is too large, it can easily generate thermal stress, which can cause significant tensile stress on the surface of the concrete foundation and form cracks. The foundation temperature is also prone to change, making it difficult to adjust the spraying water according to the foundation temperature. Summary of the Invention

[0004] This invention provides a temperature control device and method for large-volume concrete, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: A large-volume concrete temperature control device includes steel cables, a temperature control mechanism, and fixing blocks. The temperature control mechanism has steel cables fixed to both sides and connected to the fixing blocks. Adjacent temperature control mechanisms are connected in a ring or planar shape by fixing blocks. The fixing blocks on both sides of each temperature control mechanism are concave and convex, respectively. The concave and convex fixing blocks of adjacent fixing blocks fit together, and an external screw passes through to connect them. The screw passes through the fixing block and is fixed to the outside of the foundation. Each temperature control mechanism has two water pipes at its lower end, which are connected to cold and hot water respectively. The temperature control mechanism includes a track bar, a docking mechanism, a guide structure, a lifting structure, a flow pipe, a hollow groove, a main plate, and a monitor. The hollow groove is located in the middle of the main plate, and the lifting structure and its lower docking mechanism move up and down within the hollow groove. The monitors are arranged in parallel inside the main plate, with the sensing end of the monitor corresponding to the outer side of the support platform. There are two flow pipes, each connected to a water pipe. The flow pipes are located inside the main plate, with their lower ends connected to the lower water pipes. The flow pipes have guide structures arranged on their sides. The lifting structure is electrically controlled to rotate its lower docking mechanism, connecting the docking mechanism to the guide structure inside the main plate. The track bar is located on the side of the main plate. The monitor and the lifting structure are connected in parallel to an external controller. When the monitor senses a temperature difference outside the support platform, the controller electrically controls the lifting structure to engage inside the main plate, causing the lifting structure to slide up and down along the track bar. After the docking mechanism connects to the guide structure, it sprays water to control the temperature outside the support platform.

[0006] A preferred technical solution: The lifting structure includes a processor, a housing, a rotating rod, a sensor, a first motor, and a slide bar. The housing is fixed to the lower end of the first motor. The processor and the sensor are electrically connected inside the housing, and the sensor corresponds to the laser sensing of the monitor. The processor controls the docking mechanism through electrical signals. The slide bar is located on the side of the first motor. The processor drives the first motor through electrical signals, and causes the rotating rod at the output end of the first motor to engage with the inner side of the main body plate.

[0007] A preferred technical solution: The main plate is provided with a rack for meshing on the inner side of the rotating rod. The output end of the first motor meshes with the rack through the rotating rod and slides on the track of the track bar through the slide bar, so that the rotating rod is engaged in a horizontal state to drive the first motor to climb along the track bar.

[0008] A preferred technical solution: The docking mechanism includes a rod, a nozzle pipe, a transfer pipe, and a second motor. The second motor is fixed at the lower end of the housing and is electrically connected to the processor. The processor drives the rod at the output end of the second motor to rotate via electrical signals. A transfer pipe is provided at the lower end of the rod. The nozzle pipe is connected to the corner of the transfer pipe, and the transfer pipe rotates around the nozzle pipe to connect with the corresponding guide structure. The nozzle pipe sprays water in a fan shape to control the temperature on the outer side of the support platform.

[0009] A preferred technical solution: The guiding structure includes a first connecting pipe, a plastic block, a second connecting pipe, a circular support rod, an adjustment structure, and a rubber block. The rubber block is attached to the inner side of the main body plate, and the plastic block is attached to the surface of the rubber block and connected to the outer periphery of the circular support rod. The middle of the circular support rod pushes the adjustment structure fixed inside the main body plate to open and close. The first and second connecting pipes, arranged vertically, are respectively connected to two flow pipes. The circular support rod has an annular flow hole, which is connected to the control structure. The adapter pipe rotates with the circular support rod, causing the plastic block to press against the rubber block, and connecting the flow hole inside the circular support rod with the adapter pipe.

[0010] A preferred technical solution: The control structure includes a spring, a ball, a support rod, a central rod, and an open plate. The main body plate has a groove corresponding to the central rod inside. The left and right ends of the spring are fixed to the inner side of the groove and the side of the central rod. The open plate is fixed inside the main body plate. A support rod connected to the ball is provided in the middle of the central rod. When the spring is stationary, the ball elastically abuts against the through hole structure in the middle of the open plate. The circular support rod elastically pushes the central rod, causing the ball to open and close in the through hole structure of the open plate.

[0011] A method for temperature control of large-volume concrete, based on the aforementioned temperature control device for large-volume concrete, comprises the following steps: S1: Installation: The temperature control mechanism is fixed to the outside of the base by fixing blocks, and the steel cable is bent in an arc shape according to the shape of the base, so that the adjacent temperature control mechanisms match the concave and convex positions of the fixing blocks. Then the screw passes through the matching position and is fixed to the outside of the base. The fixing blocks are assembled at the same time as the base is installed in a flat or arc shape according to the shape of the base. S2: Movement: The water pipe at the lower end of the temperature control mechanism is connected to external cold and hot water pipes, allowing water to flow under pressure from the inside of the flow pipe to the arranged guide structure. According to the temperature on the outside of the support platform sensed by the hollow groove sensing end, when the arranged monitors sense the temperature difference, they control the lifting structure drive through the electrical signal of the wire connected to the lifting structure. Thus, the rotating rod meshes with the rack on the inside of the main plate, and under the guidance of the track bar, the slide bar at the left end of the first motor slides on the track bar, so that the lifting structure drives the docking mechanism to rise and fall horizontally along the track bar. S3: Connection: When the lifting structure moves up and down, the sensor detects the height of the monitor position where the temperature is abnormal. At this time, the docking mechanism moves to the right of the corresponding monitor, and then the processor controls the second motor to rotate with an electrical signal. The second motor then rotates along the central axis of the nozzle pipe, so that the transfer pipe rotates to the guide structure to connect, allowing water to flow from the guide structure into the transfer pipe and spray in a fan shape from the nozzle pipe to the outside of the pier.

[0012] S4: Temperature Control: When the temperature of the pier is high, the second motor will drive the motor rod to rotate to a horizontally upward position. At this time, the circular support rod corresponding to the transfer pipe will tilt upward and drive the support rod and the ball to rotate downward around the center rod. Then the ball will approach the outlet of the first pipe, so the outlet of the first pipe will be blocked by the ball, and the outlet of the second pipe will be freed from the blockage of the ball. This makes the water flow of the first pipe smaller than that of the second pipe. Then the water temperature after the water flowing out of the second pipe and the first pipe is mixed is lower. The mixed water passes through the through hole structure of the opening plate, passes through the circular support rod and is introduced into the transfer pipe. Then it flows to the nozzle pipe and sprays water to regulate the temperature of the outside of the pier.

[0013] Compared with existing technologies, this technical solution has the following advantages: In this invention, when the monitor senses a temperature difference using laser, an electrical signal is transmitted to the lifting structure, which then controls the docking mechanism to slide and lift along the inner track of the track bar. This allows the docking mechanism to move to the side of the monitor at the temperature difference location for sensing. The lifting structure then controls the docking mechanism to rotate and dock with the guide structure. The docking mechanism connects to the guide structure to draw out water flow, precisely spraying water to control the temperature difference at various locations on the outer side of the foundation, preventing uneven temperature distribution at different locations on the foundation from affecting the solidification and molding of the concrete foundation.

[0014] In this invention, the circular support rod is horizontally pressed by the adapter pipe, and the central rod is pushed horizontally within the groove by the spring elasticity. At this time, the ball will abut against the middle of the first and second connectors, thereby causing the ball to disengage from the through hole structure of the opening plate through the central rod. According to the movement of the circular support rod by the adapter pipe, the volume of the ball blocking the outlets of the first and second connectors is adjusted, thereby controlling the sprayed water temperature. When the monitor senses the temperature of the foundation, the sprayed water temperature is adjusted according to the temperature at each position of the foundation, so that the difference between the sprayed water temperature and the temperature outside the foundation is within 15°C, avoiding excessive temperature difference between the sprayed water temperature and the temperature outside the foundation, which would cause temperature stress and prevent cracks from occurring during spraying maintenance.

Detailed Implementation

[0024] like Figures 1 to 7 As shown, the present invention proposes a large-volume concrete temperature control device, including a steel cable 1, a temperature control mechanism 2, and a fixing block 3. The temperature control mechanism 2 is fixed with steel cables 1 connected to the fixing block 3 on both sides, and adjacent temperature control mechanisms 2 are spliced ​​together in a ring or planar shape by fixing blocks 3. The fixing blocks 3 on both sides of each temperature control mechanism 2 are concave and convex respectively. The concave and convex of adjacent fixing blocks 3 fit together, and an external screw passes through to connect them. The screw passes through the fixing block 3 and is fixed to the outside of the foundation. Each temperature control mechanism 2 is provided with two water pipes at the lower end, which are connected to cold and hot water respectively. The temperature control mechanism 2 includes a track bar 21, a docking mechanism 22, a guide structure 23, a lifting structure 24, a flow pipe 25, a hollow groove 26, a main body plate 27, and a monitor 28. The hollow groove 26 is located in the middle of the main body plate 27, and the lifting structure 24 and its lower docking mechanism 22 move up and down within the hollow groove 26. The monitors 28 are arranged in parallel inside the main body plate 27, with the sensing end of the monitor 28 corresponding to the outer side of the support platform. There are two flow pipes 25, each connected to a water pipe. The flow pipes 25 are located inside the main body plate 27, with their lower ends connected to the lower water pipes. The side of the main plate 27 is provided with a guide structure 23 arranged in a row. The lifting structure 24 is electrically controlled to rotate the docking mechanism 22 at its lower end, and the docking mechanism 22 is connected to the guide structure 23 on the inner side of the main plate 27. The track bar 21 is provided on the side of the main plate 27. The monitor 28 and the lifting structure 24 are connected to an external controller in parallel. When the monitor 28 senses the temperature difference on the outside of the platform, it controls the lifting structure 24 to engage and move on the inner side of the main plate 27 through the controller's electrical signal, and the lifting structure 24 slides up and down along the track bar 21. After the docking mechanism 22 is connected to the guide structure 23, water is sprayed on the outer side of the platform to control the temperature.

[0025] Furthermore, the hot and cold water pipes connected to the flow pipe 25 are maintained under a relatively high water pressure. The monitor 28 is connected in parallel with the lifting structure 24 and then connected to an external controller via an electric wire. In this invention, the output end of the monitor 28 is located on the outer side of the support platform, and it senses the temperature through a laser electrical signal. The input end of the monitor 28 is located on one side of the docking mechanism 22, thus having the effect of laser sensing of the docking mechanism 22. When the monitor 28 senses a temperature difference, the electrical signal is transmitted to the lifting structure 24, which controls the docking mechanism 22 to slide and rise on the inner side of the track 21. As a result, the track of the docking mechanism 22 moves to the side of the monitor 28 at the temperature difference position for sensing. Then, the sensing signal emitted by the monitor 28 is processed by the processor and controls the lifting structure 24, which in turn controls the docking machine. The rotating guide structure 23 of the structure 22 allows water inside the flow pipe 25 to be drawn out from the guide structure 23 and sprayed onto the foundation by the docking mechanism 22. Furthermore, based on the temperature detected by the monitor 28, if it is too high or too low, the external controller sends a command to the lifting structure 24 and controls the rotation angle of the docking mechanism 22, thereby regulating the amount of water drawn out of the flow pipe 25 by the guide structure 23. The water temperature is regulated by the control of the hot and cold water output by the guide structure 23, and the foundation is precisely sprayed with water to control the temperature. Then, under the lifting and docking of the lifting structure 24 and the docking mechanism 22, the docking mechanism 22 connects to the guide structure 23 to draw out water flow, and precisely sprays water to control the temperature at various locations on the outside of the foundation to prevent uneven temperature at various locations on the foundation from affecting the solidification and forming of the concrete foundation.

[0026] Furthermore, the sprayed water flows down the outer wall of the foundation, further controlling the temperature of the area below. When multiple monitors 28 monitor the foundation temperature, the docking mechanism 22 is controlled to move to the corresponding position for spraying based on the temperature changes in each area. The docking mechanism 22 is also controlled to continuously operate, so that spraying continues uninterrupted whenever the temperature of each position on the outer side of the foundation changes slightly. This prevents the foundation temperature from rising too much and controls the foundation temperature while preventing the temperature of the sprayed water from differing too much from the foundation temperature.

[0027] Furthermore, the steel cable 1 is made of soft steel cable, which has a bending effect, and the upper and lower ends of the temperature control mechanism 2 are arc-shaped structures corresponding to one side of the support platform. When the fixing blocks 3 on two adjacent temperature control mechanisms 2 meet with concave and convex surfaces, the screw passes through the meeting position and is screwed and fixed to the surface of the support platform. At this time, the two edges of the arc-shaped surface of the temperature control mechanism 2 are close to the outer side of the support platform, while a space is generated between the middle of the temperature control mechanism 2 and the outer side of the support platform, providing a spraying space for the temperature control mechanism 2 to spray the outer side of the support platform. The adjacent temperature control mechanisms 2 are arranged in a planar state on the planar support platform through the soft movement of the steel cable 1. Thus, according to the shape of the support platform, multiple temperature control mechanisms 2 can be spliced ​​together and installed according to the shape of the support platform, which is suitable for arc-shaped or planar support platforms.

[0028] The lifting structure 24 includes a processor 241, a housing 242, a rotating rod 243, a sensor 244, a first motor 245, and a slide bar 246. The housing 242 is fixed to the lower end of the first motor 245. The processor 241 and the sensor 244 are electrically connected inside the housing 242. The sensor 244 corresponds to the laser sensing of the monitor 28 and is driven by the docking mechanism 22 through the electrical signal of the processor 241. The slide bar 246 is located on the side of the first motor 245. The processor 241 drives the first motor 245 through electrical signal, and causes the rotating rod 243 at the output end of the first motor 245 to engage with the inner side of the main body plate 27.

[0029] The main plate 27 is provided with a rack 101 for meshing on the inner side of the rotating rod 243. The output end of the first motor 245 is engaged with the rack 101 through the rotating rod 243. The first motor 245 is moved along the track of the track bar 21 by sliding the slide bar 246, so that the rotating rod 243 is engaged in a horizontal state to drive the first motor 245 to climb along the track bar 21.

[0030] Furthermore, the output end of the rotating rod 243 engages with the rack 101 on the inner side of the main body plate 27, and slides on the track within the track bar 21 via the slider 246 at the left end of the first motor 245, keeping the rotating rod 243 in a horizontal state to engage with the rack 101 and move up and down. When the sensor 244 moves up and down to the input end of the corresponding monitor 28, the processor 241 inside the housing 242 controls the first motor 245 to stop moving. Then, the housing 242 synchronously controls the docking mechanism 22 to drive, and moves the lifting structure 24 to the corresponding position according to the abnormal temperature position sensed by the monitor 28. When the rotating rod 243 moves up and down, due to the limitation of the slider 246 by the track bar 21, the right end of the rotating rod 243 will not contact the guide structure 23 on the inner side of the main body plate 27.

[0031] The docking mechanism 22 includes a rod 221, a nozzle pipe 222, a transfer pipe 223, and a second motor 224. The second motor 224 is fixed to the lower end of the housing 242 and is electrically connected to the processor 241. The processor 241 drives the rod 221 at the output end of the second motor 224 to rotate via electrical signals. The lower end of the rod 221 is provided with a transfer pipe 223. The nozzle pipe 222 is connected to the corner of the transfer pipe 223, and the transfer pipe 223 rotates around the nozzle pipe 222 to connect with the corresponding guide structure 23. The nozzle pipe 222 sprays water in a fan shape to control the temperature on the outer side of the support platform.

[0032] Furthermore, the nozzle pipe 222 has a fan-shaped guide bar inside, which enables the water to be sprayed in a fan shape. The motor rod 221 at the output end of the second motor 224 is located in the middle position and rotates horizontally, which can drive the lower end of the adapter pipe 223 to rotate. Thus, when the adapter pipe 223 rotates, it rotates around the nozzle pipe 222 as the central axis, thereby keeping the nozzle pipe 222 in the position corresponding to the outer side of the support platform. At the same time, the water introduced after the adapter pipe 223 connects to the guide structure 23 is sprayed from the nozzle pipe 222 in a fan shape. The rotation of the adapter pipe 223 is between a vertical state relative to the main body plate 27 and a counterclockwise rotation of 100°.

[0033] The guide structure 23 includes a first connecting pipe 231, a plastic block 232, a second connecting pipe 233, a circular support rod 234, an adjustment structure 235, and a rubber block 236. The rubber block 236 is attached to the inner side of the main body plate 27, and the plastic block 232 is attached to the surface of the rubber block 236 and connected to the periphery of the circular support rod 234. The circular support rod 234 pushes the adjustment structure 235, which is fixed inside the main body plate 27, to open and close. The first connecting pipe 231 and the second connecting pipe 233, which are arranged vertically, are respectively connected to two flow pipes 25. The circular support rod 234 has an annular flow hole, which is connected to the control structure 235. The adapter pipe 223 rotates in response to the circular support rod 234, causing the plastic block 232 to press against the rubber block 236, and connecting the flow hole inside the circular support rod 234 with the adapter pipe 223.

[0034] Furthermore, the central protrusion of the circular support rod 234 connects to the central rod 2354. The circular support rod 234 has four circular holes for water to flow through. When the adapter pipe 223 rotates to 90°, it presses down on the circular support rod 234, causing the second adapter pipe 233 and the circular support rod 234 to move elastically with the control structure 235. As a result, the plastic block 232 on the periphery of the circular support rod 234 is pressed against the adapter pipe 223 by the elasticity of the rubber block 236, preventing gaps from forming between the adapter pipe 223 and the plastic block 232. Thus, the holes in the circular support rod 234 are connected to the adapter pipe 223, allowing the water flowing through the second adapter pipe 233 and the first adapter pipe 231 to be drawn out.

[0035] Furthermore, when the adapter pipe 223 rotates 90°, the holes of the adapter pipe 223 and the circular support rod 234 are connected, and the circular support rod 234 remains horizontal to guide the water out of the second pipe 233 and the first pipe 231. At this time, the water flow rates of the second pipe 233 and the first pipe 231 are the same. When the adapter pipe 223 rotates counterclockwise more than 90°, under the elasticity of the rubber block 236, the adapter pipe 223 presses the circular support rod 234 and pushes the control structure 235 to move horizontally while causing the circular support rod 234 to tilt. At this time, the right end of the control structure 235 tilts downward while being pushed horizontally by the circular support rod 234. This adjusts the structure 235 so that it is closer to the outlet of the first connector 231 and further away from the outlet of the second connector 233. Thus, the first connector 231 is connected to hot water, and the second connector 233 is connected to cold water. When the adapter 223 is rotated counterclockwise more than 90°, the outlet of the first connector 231 is more obstructed, and the amount of hot water flowing out of the first connector 231 is less than the amount of cold water flowing out of the second connector 233, resulting in a lower temperature of the mixed water. Therefore, when the adapter 223 is rotated counterclockwise to a position slightly below 90°, the mixed water has a higher temperature, and the mixing temperature of the hot and cold water is adjusted according to the rotation angle of the adapter 223.

[0036] The control structure 235 includes a spring 2351, a ball 2352, a support rod 2353, a central rod 2354, and an opening plate 2355. The main body plate 27 has a groove corresponding to the central rod 2354 inside. The left and right ends of the spring 2351 are fixed to the inner side of the groove and the side of the central rod 2354. The opening plate 2355 is fixed inside the main body plate 27. The support rod 2353 connected to the ball 2352 is provided in the middle of the central rod 2354. When the spring 2351 is stationary, the ball 2352 elastically abuts against the through hole structure in the middle of the opening plate 2355. The circular support rod 234 elastically pushes the central rod 2354, causing the ball 2352 to open and close in the through hole structure of the opening plate 2355.

[0037] Furthermore, when the adapter pipe 223 is stationary and vertical, when it rotates counterclockwise to 100°, it will cause the ball 2352 to completely block the first connector 231. At this time, the mixing temperature of the first connector 231 and the second connector 233 is controlled at 25°C. When the adapter pipe 223 rotates counterclockwise to 80°, it will cause the ball 2352 to completely block the second connector 233. At this time, the mixing temperature of the first connector 231 and the second connector 233 is controlled at 55°C. Within this 10° range of approximately 90°, the mixing ratio of the water output of the first connector 231 and the second connector 233 is adjusted to keep the spraying temperature between 55°C and 25°C. For the connection between the adapter pipe 223 and the circular support rod 234, the second connector 233 needs to be rotated to 90° to press the circular support rod 234 and then rotated again for adjustment to avoid incomplete connection between the second connector 233 and the circular support rod 234 when it is rotated to 80°.

[0038] Furthermore, the temperature on the outside of the concrete foundation needs to be maintained at the standard line of 40℃, while the spraying temperature is controlled between 55℃ and 25℃. The spraying temperature can be controlled between 70℃ and 10℃. Based on the temperature sensed by the monitor 28, the spraying temperature is adjusted to keep the spraying temperature and the outside temperature of the foundation within 15℃, and cooling curing is carried out within a 15℃ difference.

[0039] In this invention, when the circular support rod 234 is horizontally pressed by the adapter pipe 223 and the central rod 2354 is elastically pushed by the spring 2351 to move horizontally within the groove, the sphere 2352 will abut against the middle of the first adapter pipe 231 and the second adapter pipe 233. This allows the central rod 2354 to drive the sphere 2352 out of the through-hole structure of the opening plate 2355, facilitating the flow of the mixed water from the first adapter pipe 231 and the second adapter pipe 233 through the through-hole structure. Furthermore, based on the pushing action of the circular support rod 234, the sphere 2352 aligns with the first adapter pipe 231 and the second adapter pipe 2353. 3. The ball 2352 is adjusted to block the outlets of the first and second pipes 231 and 233 by the circular support rod 234 driven by the transfer pipe 223, thereby controlling the water output of the first and second pipes 231 and controlling the sprayed water temperature. When the monitor 28 senses the temperature of the pier, the sprayed water temperature is adjusted according to the temperature of each position of the pier, so that the sprayed water temperature is within 15°C of the temperature of the outside of the pier, so as to avoid the temperature difference between the sprayed water temperature and the temperature of the outside of the pier being too large and forming temperature stress, and to prevent cracks from occurring during spraying maintenance.

[0040] A method for temperature control of large-volume concrete, based on the aforementioned temperature control device for large-volume concrete, comprises the following steps: S1: Installation: The temperature control mechanism 2 is fixed to the outside of the support platform by the fixing block 3, and the steel cable 1 is bent in an arc shape according to the shape of the support platform, so that the adjacent temperature control mechanisms 2 match the concave and convex positions of the fixing block 3, and then the screw passes through the matching position and is fixed to the outside of the support platform. The fixing block 3 is assembled and installed according to the shape of the support platform in a plane or arc shape. S2: Movement: The water pipe at the lower end of the temperature control mechanism 2 is connected to external cold and hot water pipes, so that water flows under pressure from the inside of the flow pipe 25 to the guide structure 23 arranged in a row. According to the temperature of the outer side of the support platform sensed by the sensing end of the hollow groove 26, when the arranged monitor 28 senses the temperature difference, it controls the lifting structure 24 to drive through the electrical signal of the wire connected to the lifting structure 24. Thus, the rotating rod 243 meshes with the rack 101 on the inner side of the main plate 27, and under the guidance of the track bar 21, the slide bar 246 at the left end of the first motor 245 slides in the track bar 21, so that the lifting structure 24 drives the docking mechanism 22 to rise and fall horizontally along the track bar 21. S3: Connection: When the lifting structure 24 moves up and down, the sensor 244 senses the height of the position of the temperature abnormality monitor 28. At this time, the docking mechanism 22 moves to the right of the corresponding monitor 28, and then the processor 241 controls the second motor 224 to rotate with an electrical signal. Then, the second motor 224 is controlled to rotate along the central axis of the nozzle pipe 222, so that the transfer pipe 223 rotates to the guide structure 23 to connect, so that water flows from the guide structure 23 into the transfer pipe 223 and is sprayed in a fan shape from the nozzle pipe 222 to the outside of the support platform.

[0041] S4: Temperature control: When the temperature of the pier is high, the second motor 224 will drive the motor rod 221 to rotate to a horizontally upward position. At this time, the circular support rod 234 corresponding to the transfer pipe 223 will tilt upward and drive the support rod 2353 and the ball 2352 to rotate downward around the central rod 2354. Then the ball 2352 will approach the outlet of the first pipe 231, so the outlet of the first pipe 231 will be blocked by the ball 2352. The outlet of the second pipe 233 will be freed from the blockage of the ball 2352, so that the water output of the first pipe 231 is smaller than that of the second pipe 233. Then the water temperature after the water from the second pipe 233 and the water from the first pipe 231 are mixed is lower. The mixed water passes through the through hole structure of the opening plate 2355, passes through the circular support rod 234 and is introduced into the transfer pipe 223. Then it flows to the nozzle pipe 222 and sprays water to regulate the temperature of the outside of the pier.

[0042] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.

7. A method for temperature control of large-volume concrete, based on the temperature control device for large-volume concrete as described in claim 6, characterized in that, The specific method is as follows: S1: Installation: The temperature control mechanism is fixed to the outside of the base by fixing blocks, and the steel cable is bent in an arc shape according to the shape of the base, so that the adjacent temperature control mechanisms match the concave and convex positions of the fixing blocks. Then the screw passes through the matching position and is fixed to the outside of the base. The fixing blocks are assembled at the same time as the base is installed in a flat or arc shape according to the shape of the base. S2: Movement: The water pipe at the lower end of the temperature control mechanism is connected to external cold and hot water pipes, allowing water to flow under pressure from the inside of the flow pipe to the arranged guide structure. According to the temperature on the outside of the support platform sensed by the hollow groove sensing end, when the arranged monitors sense the temperature difference, they control the lifting structure drive through the electrical signal of the wire connected to the lifting structure. Thus, the rotating rod meshes with the rack on the inside of the main plate, and under the guidance of the track bar, the slide bar at the left end of the first motor slides on the track bar, so that the lifting structure drives the docking mechanism to rise and fall horizontally along the track bar. S3: Connection: When the lifting structure moves up and down, the sensor detects the height of the monitor position where the temperature is abnormal. At this time, the docking mechanism moves to the right of the corresponding monitor, and then the processor controls the second motor to rotate with an electrical signal. The second motor then rotates along the central axis of the nozzle pipe, so that the transfer pipe rotates to the guide structure to connect, allowing water to flow from the guide structure into the transfer pipe and spray in a fan shape from the nozzle pipe to the outside of the support platform. S4: Temperature Control: When the temperature of the pier is high, the second motor will drive the motor rod to rotate to a horizontally upward position. At this time, the circular support rod corresponding to the transfer pipe will tilt upward and drive the support rod and the ball to rotate downward around the center rod. Then the ball will approach the outlet of the first pipe, so the outlet of the first pipe will be blocked by the ball, and the outlet of the second pipe will be freed from the blockage of the ball. This makes the water flow of the first pipe smaller than that of the second pipe. Then the water temperature after the water flowing out of the second pipe and the first pipe is mixed is lower. The mixed water passes through the through hole structure of the opening plate, passes through the circular support rod and is introduced into the transfer pipe. Then it flows to the nozzle pipe and sprays water to regulate the temperature of the outside of the pier.
