Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling devices, in particular to a self-circulation cooling device for large-volume prestressed concrete corrugated cooling pipes. BACKGROUND

[0002] Temperature stress in large-volume concrete is one of the most common causes of concrete cracking, especially during the construction period of large-volume concrete. If the heat generated by hydration of concrete cannot be effectively and uniformly dissipated, a large temperature stress will be formed, which will cause concrete cracking and quality accidents. Therefore, the quality of temperature control of large-volume concrete directly affects the construction quality of large-volume concrete, and is the key to the quality control of large-volume concrete construction, especially for large-volume concrete that bears load, such as thin-walled high arch dams. Controlling the internal and external temperature difference of concrete and temperature deformation (stress) is the key to improving the impermeability, crack resistance and corrosion resistance of concrete. The industry generally adopts the following four measures: selecting a low-heat concrete mix ratio, burying cooling water pipes to reduce temperature by circulating cold water, monitoring the temperature during concrete curing, and external thermal curing of concrete.

[0003] At present, the cooling of concrete is mainly achieved by burying cooling water pipes, but the existing cooling technology through cooling water pipes still has the following shortcomings:

[0004] 1. When the cooling water pipe carries away the heat in the concrete, the cooling water in the cooling water pipe contains heat, and the existing method cannot quickly dissipate the heat contained in the cooling water, so that the cooling water cannot effectively carry away the heat in the concrete in the later stage;

[0005] 2. In the existing technology, when the cooling water temperature reaches a certain degree, the cooling water needs to be replaced to achieve the purpose of subsequent cooling of the concrete. However, frequent replacement of cooling water not only wastes water resources, but also takes a lot of time to replace the cooling water, affecting the cooling of the concrete in the later stage.

[0006] In view of the above problems, the present application provides a self-circulation cooling device for large-volume prestressed concrete corrugated cooling pipes. SUMMARY

[0007] The present application provides a self-circulation cooling device for large-volume prestressed concrete corrugated cooling pipes, which solves the problem that the heat contained in the cooling water cannot be quickly dissipated and the replacement of the cooling water wastes water resources.

[0008] The present application provides the following technical solutions:

[0009] A self-circulation cooling device for large-volume prestressed concrete corrugated cooling pipes, comprising: a cooling pipe, the cooling pipe is pre-buried in the concrete;

[0010] The pre-cooling structure, one end of the cooling pipe extends to one side of the concrete and communicates with the pre-cooling structure, is used for preliminarily cooling the cooling water;

[0011] The air cooling structure is used for further cooling the cooling water;

[0012] The liquid changing structure is used for changing the cooling water which cannot be further cooled.

[0013] In a possible design, the pre-cooling structure includes a saltwater tank, one end of the cooling pipe extends into the saltwater tank and is fixedly connected with a spiral pipe, one end of the spiral pipe fixedly connected with a connecting pipe which penetrates the saltwater tank, one end of the connecting pipe is fixedly connected with a drain pipe, the cooling water in the cooling pipe carries the heat in the concrete into the spiral pipe, and the cooling water is preliminarily cooled through the specific heat capacity difference between the saltwater and the cooling water.

[0014] In a possible design, the air cooling structure includes a cooling box, the cooling box is fixedly connected with a partition plate, the cooling box forms a first cavity and a second cavity through the partition plate, the second cavity is fixedly connected with a rotating shaft, the outer wall of the rotating shaft is rotatably sleeved with a rotating wheel, the outer wall of the rotating wheel is fixedly connected with a plurality of water receiving plates, and the bottom end of the drain pipe is located above one side of the rotating wheel, the outer wall of the rotating wheel is fixedly connected with a plurality of water containing barrels, the second cavity is fixedly connected with a water guide box which penetrates the partition plate, the inner wall of the bottom of the water guide box is fixedly connected with activated carbon, one end of the water containing barrel close to the water guide box is slightly lower than the other end away from the water guide box, the cooling water is sprayed downward to the water receiving plates through the drain pipe, the gravity of the water flow and the impact force of the water flow not only drive the rotating wheel and the water receiving plates to rotate, but also cause the cooling water to splash and form water splashes when the water flow descends and hits the water receiving plates, thereby increasing the contact area with the air, rapidly dissipating the heat to the air, and the rotating wheel drives the water containing barrels to rotate, which can stir the cooling water in the second cavity and accelerate the cooling of the cooling water, the water containing barrels can collect part of the cooling water in the rotating process, and when the water containing barrels rotate to the top, the cooling water in the water containing barrels flows into the water guide box, the activated carbon can filter the impurities in the cooling water, avoiding that too many impurities cause the cooling pipe to be blocked.

[0015] In a possible design, the air cooling structure further includes a cooling step fixedly connected in the first cavity and located below the water guide box, and the bottom inner wall of the first cavity is fixedly connected with a circular pipe, the water guide box guides the cooling water to the cooling step, the cooling water flows on the cooling step, increasing the contact area between the cooling water and the air and dissipating the heat in the cooling water.

[0016] In one possible design, the fluid changing structure includes a changing platform. A rotating disk is rotatably connected to the bottom inner wall of the changing platform. Multiple water storage tanks, which mate with circular pipes, are arranged in a ring on the top of the rotating disk, with the water storage tanks located below the circular pipes. A second liquid pipe rotatably passes through the changing platform, and the top end of the second liquid pipe rotatably passes through the rotating disk. A first liquid pipe, communicating with the second liquid pipe, is fixedly connected to one side of each water storage tank. A valve is fitted onto the outer wall of the first liquid pipe. A toothed ring is fixedly fitted onto the outer wall of the rotating disk. A drive motor is fixedly connected to one side of the changing platform. The machine has an output shaft that extends into the changing table and is fixedly connected to a gear, which meshes with a gear ring. When the temperature of the cooling water in the storage tank cannot be further reduced, the drive motor is started to drive the rotating disk to rotate, moving the prepared storage tank to the bottom of the circular tube. The previous storage tank can then be cooled quietly on one side until the cooling water returns to room temperature. The brine in the changing table can also cool the cooling water in the storage tank, which not only saves cooling water but also allows for quick replacement of the cooling water, preventing the concrete from cracking due to insufficient cooling.

[0017] In one possible design, a water pump is provided on one side of the concrete. The inlet of the water pump is fixedly fitted with an inlet pipe, which is connected to the bottom end of a second pipe. The outer wall of the inlet pipe is fixedly fitted with a sealing ring, and one end of the second pipe extends into the sealing ring and is rotatably connected to the sealing ring. The sealing ring can increase the sealing between the second pipe and the inlet pipe when the rotating disk drives the second pipe to rotate. The outlet of the water pump is fixedly fitted with an outlet pipe, which is connected to one end of a cooling pipe.

[0018] In one possible design, a Tesla valve is fixedly connected to one end of the connecting pipe, and the end of the Tesla valve away from the connecting pipe is connected to the drain pipe. The cooling water, after initial cooling, enters the Tesla valve from the connecting pipe. Through the principle of the Tesla valve, the flow rate of the cooling water increases, which can increase the flow rate of the water sprayed from the drain pipe, thereby driving the rotating wheel to rotate and further cooling the cooling water in the later stage.

[0019] In one possible design, the cooling tank has multiple first conical holes and second conical holes on its opposite sides. The smaller inner diameter ends of the first and second conical holes are connected to the first and second cavities, respectively. Due to the temperature contained in the cooling water, the heat in the first and second cavities dissipates upwards, resulting in low air pressure inside the first and second cavities. At this time, cold air from the outside flows into the first and second cavities through the first and second conical holes, respectively. The flow rate of the cold air increases when it passes through the first and second conical holes. The cold air entering the first conical hole blows towards the cooling step, accelerating the dissipation of heat from the cooling water on the cooling step. The cold air entering the second conical hole blows upwards at an angle, rapidly pushing the heat in the second cavity upwards. The upwardly blowing cold air can also provide power for the rotation of the rotating wheel through the water receiving plate.

[0020] In one possible design, the cooling box has a through hole located below the cooling step. Multiple heat-conducting pipes are fixedly inserted through the cooling box and pass through the second cavity. Baffles are fixedly connected to the top inner wall and bottom of the heat-conducting pipes. Because the cooling box has a through hole, the airflow increases when outside air enters the through hole, creating wind. This flowing wind can carry away the heat contained in the cooling water on the cooling step, further reducing the temperature of the cooling water. Similarly, the heat of the cooling water in the second cavity can be discharged through the multiple heat-conducting pipes. The baffles allow the air inside the heat-conducting pipes to flow rapidly, and the flowing air can carry away the heat in the second cavity through the heat-conducting pipes.

[0021] In one possible design, the bottom of the brine tank is equipped with a circulating pipe, and the other end of the circulating pipe is connected to the replacement platform. A solenoid valve is fitted on the outer wall of the circulating pipe, and a duct is fixedly connected to the bottom inner wall of the through hole. The duct is located directly above the replacement platform. When the brine temperature in the brine tank reaches a certain level and cannot effectively pre-cool the cooling water in the spiral tube, the solenoid valve is activated. The hot brine in the brine tank enters the replacement platform through the circulating pipe. A pump (not shown in the figure) pumps the low-temperature brine in the replacement platform into the brine tank, realizing the exchange of brine. The cooling tank is equipped with a through hole, so that outside air can quickly pass through the through hole. The air entering the through hole can carry away the heat of the cooling water on the cooling step. The air in the through hole can also be blown into the replacement platform through the duct, so that the brine can be quickly cooled in the replacement platform. The brine can be recycled to quickly cool the cooling water in the spiral tube and the water storage tank.

[0022] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0023] In this invention, one end of the cooling pipe extends into the brine tank and is fixedly connected to a spiral pipe. The end of the spiral pipe away from the cooling pipe is fixedly connected to a connecting pipe that passes through the brine tank. One end of the connecting pipe is fixedly connected to a drain pipe. The cooling water in the cooling pipe carries the heat in the concrete into the spiral pipe, and the cooling water is initially cooled by the specific heat capacity difference between the brine and the cooling water.

[0024] In this invention, a rotating shaft is fixedly connected to the second cavity, and a rotating wheel is rotatably sleeved on the outer wall of the rotating shaft. Multiple water receiving plates are fixedly connected to the outer wall of the rotating wheel, and multiple water-holding cylinders are fixedly connected to the outer wall of the rotating wheel. A water inlet tank is fixedly connected to the second cavity. Cooling water is sprayed down onto the water receiving plates through a drain pipe. The gravity and impact force of the water flow not only drive the water receiving plates to rotate, but also cause the water to splash as it descends and hits the water receiving plates, increasing the contact area between the cooling water and the air and quickly dissipating heat into the air. The rotating wheel drives the water-holding cylinders to rotate, which can stir the cooling water in the second cavity and accelerate the cooling of the cooling water. During the rotation, the water-holding cylinders discharge the collected cooling water into the water inlet tank for further cooling of the cooling water in the later stage.

[0025] In this invention, the top of the rotating disk is provided with multiple water storage tanks, and a second liquid pipe is rotatably connected inside the replacement platform. A first liquid pipe connected to the second liquid pipe is fixedly connected to one side of each water storage tank. A gear ring is fixedly fitted on the outer wall of the rotating disk. The output shaft of the drive motor extends into the replacement platform and is fixedly connected to a gear, which meshes with the gear ring. When the temperature of the cooling water in the water storage tank cannot be further reduced, the drive motor is started to drive the rotating disk to rotate, rotating the prepared water storage tank to the bottom of the circular pipe. The brine in the replacement platform can also cool the cooling water in the water storage tank, which not only saves the waste of cooling water but also allows for quick replacement of cooling water, preventing the concrete from cracking due to insufficient cooling time.

[0026] In this invention, the cooling tanks are provided with multiple first conical holes and second conical holes on opposite sides. The smaller inner diameter ends of the first and second conical holes are connected to the first and second cavities, respectively. Due to the temperature contained in the cooling water, the heat in the first and second cavities dissipates upwards, resulting in low air pressure within the first and second cavities. Outside air flows into the first and second cavities through the first and second conical holes, respectively. The cold air entering the first conical hole blows towards the cooling steps, accelerating the dissipation of heat from the cooling water on the cooling steps. The cold air entering the second conical hole blows upwards at an angle, rapidly pushing the heat in the second cavity upwards. The upwardly blowing cold air can also provide power for the rotation of the rotating wheel through the water receiving plate.

[0027] In this invention, the cooling water can be cooled twice through the pre-cooling structure and the air-cooling structure. The cooled water enters the storage tank and can be cooled again during the replacement process, ensuring that the temperature of the cooling water reaches a certain level so that it can effectively cool the concrete. In addition, when the water temperature in the storage tank can no longer reach a certain storage level, the storage tank can be quickly replaced to continue effectively cooling the concrete and avoid wasting cooling water.

[0043] Example 1

[0044] Reference Figure 1 , Figure 2 and Figure 4 This embodiment of a large-volume prestressed concrete corrugated cooling pipe self-circulating cooling device includes: a cooling pipe 2, which is embedded in concrete 1; a pre-cooling structure 3, one end of which extends to one side of the concrete 1 and is connected to the pre-cooling structure 3 for initial cooling of the cooling water; an air-cooling structure 4 for further cooling of the cooled water; a fluid replacement structure 5 for replacing the cooling water that cannot be further cooled; and a water pump 8 is provided on one side of the concrete 1. The inlet of the pump is fixedly fitted with an inlet pipe 9, and the inlet pipe 9 is connected to the bottom end of the second liquid pipe 30. The outer wall of the inlet pipe 9 is fixedly fitted with a sealing ring 39, and one end of the second liquid pipe 30 extends into the sealing ring 39 and is rotatably connected to the sealing ring 39. The sealing ring 39 can increase the sealing between the second liquid pipe 30 and the inlet pipe 9 when the rotating disk 26 drives the second liquid pipe 30 to rotate. The outlet of the water pump 8 is fixedly fitted with an outlet pipe 10, and the outlet pipe 10 is connected to one end of the cooling pipe 2.

[0045] Reference Figure 2 The pre-cooling structure 3 includes a brine tank 11. One end of the cooling pipe 2 extends into the brine tank 11 and is fixedly connected to a spiral pipe 12. The end of the spiral pipe 12 away from the cooling pipe 2 is fixedly connected to a connecting pipe 13 that passes through the brine tank 11. One end of the connecting pipe 13 is fixedly connected to a drain pipe 7. The cooling water in the cooling pipe 2 carries the heat in the concrete 1 to the spiral pipe 12, and the cooling water is initially cooled by the specific heat capacity difference between the brine and the cooling water.

[0046] Reference Figure 1One end of the connecting pipe 13 is fixedly connected to a Tesla valve 6, and the end of the Tesla valve 6 away from the connecting pipe 13 is connected to the drain pipe 7. The cooling water that has been initially cooled enters the Tesla valve 6 from the connecting pipe 13. Through the principle of the Tesla valve 6, the flow rate of the cooling water increases, which can increase the flow rate of the water sprayed out from the drain pipe 7, which is used to drive the rotating wheel 19 to rotate, and further cool the cooling water in the later stage.

[0047] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7 The air-cooled structure 4 includes a cooling box 14. A partition 15 is bolted inside the cooling box 14, forming a first cavity 16 and a second cavity 17. A rotating shaft 18 is bolted inside the second cavity 17. A rotating wheel 19 is rotatably mounted on the outer wall of the rotating shaft 18. Multiple water receiving plates 20 are bolted to the outer wall of the rotating wheel 19, and the bottom end of the drain pipe 7 is located above one side of the rotating wheel 19. Multiple water-holding cylinders 21 are bolted to the outer wall of the rotating wheel 19. A water inlet tank 22, penetrating the partition 15, is fixedly connected inside the second cavity 17. Activated carbon 43 is fixedly connected to the bottom inner wall of the water inlet tank 22. The end of the water-holding cylinder 21 closest to the water inlet tank 22 is slightly lower than the end furthest from the water inlet tank 22. Cooling water is sprayed through the drain pipe 7 onto the water receiving plate 20 below. The gravity and impact of the water flow not only drive the rotating wheel 19 and the water receiving plate 20 to rotate, but also cause the cooling water to splash as it descends and hits the water receiving plate 20, thus increasing the contact area with the air and quickly dissipating heat into the air. The rotating wheel 19 also drives the water container 21 to rotate, which can stir the cooling water in the second chamber 17 and accelerate the cooling of the cooling water. The water container 21 can collect some cooling water during rotation. As the rotating wheel 19 rotates, when the water container 21 rotates to the top, the cooling water in the water container 21 flows into the water inlet tank 22. The activated carbon 43 can filter impurities in the cooling water to prevent excessive impurities from clogging the cooling pipe 2.

[0048] Reference Figure 4 The air-cooled structure 4 also includes a cooling step 23 that is fixedly connected to the first cavity 16 by bolts, and the cooling step 23 is located below the water tank 22. A round pipe 24 is fixedly connected to the bottom inner wall of the first cavity 16 by bolts. The water tank 22 guides the cooling water to the cooling step 23. The cooling water flows on the cooling step 23, increasing the contact area between the cooling water and the air, and dissipating the heat in the cooling water.

[0049] Reference Figure 4The cooling tank 14 has multiple first conical holes 35 and second conical holes 36 on its opposite sides. The smaller inner diameter ends of the first conical holes 35 and second conical holes 36 are connected to the first cavity 16 and the second cavity 17, respectively. Due to the temperature contained in the cooling water, the heat in the first cavity 16 and the second cavity 17 dissipates upward, resulting in low air pressure in the first cavity 16 and the second cavity 17. At this time, cold air from the outside flows into the first cavity 16 and the second cavity 17 through the first conical holes 35 and the second conical holes 36, respectively. When passing through the first conical holes 35 and the second conical holes 36, the flow rate of the cold air increases. The cold air entering the first conical hole 35 blows towards the cooling step 23, accelerating the dissipation of heat in the cooling water on the cooling step 23. The cold air entering the second conical hole 36 blows upward at an angle, quickly blowing the heat in the second cavity 17 upward. The upward-blown cold air can also provide power for the rotation of the rotating wheel 19 through the water receiving plate 20.

[0050] Reference Figure 4 The cooling box 14 has a through hole 34 located below the cooling step 23. Multiple heat-conducting pipes 37 are fixedly inserted through the cooling box 14 and pass through the second cavity 17. The top inner wall and bottom of the heat-conducting pipes 37 are fixedly connected to baffles 38 by bolts. Because the cooling box 14 has a through hole 34, when outside air enters the through hole 34, it can increase the air flow rate and form wind. At this time, the flowing wind can carry away the heat contained in the cooling water on the cooling step 23, further reducing the temperature of the cooling water. Similarly, the heat of the cooling water in the second cavity 17 can be discharged through the multiple heat-conducting pipes 37. The baffles 38 can make the air in the heat-conducting pipes 37 flow quickly, and the flowing air can carry away the heat in the second cavity 17 through the heat-conducting pipes 37.

[0051] Reference Figure 6The fluid replacement structure 5 includes a replacement platform 25. A rotating disk 26 is rotatably connected to the bottom inner wall of the replacement platform 25. Multiple water storage tanks 27, which cooperate with circular pipes 24, are arranged in a ring on the top of the rotating disk 26, and the water storage tanks 27 are located below the circular pipes 24. A second liquid pipe 30 rotatably passes through the replacement platform 25, and the top end of the second liquid pipe 30 rotatably passes through the rotating disk 26. A first liquid pipe 28, which communicates with the second liquid pipe 30, is bolted to one side of the water storage tanks 27. A valve 29 is fitted on the outer wall of the first liquid pipe 28. A toothed ring 31 is fixedly fitted on the outer wall of the rotating disk 26. A drive motor 3 is bolted to one side of the replacement platform 25. 2. The output shaft of the drive motor 32 extends into the changing table 25 and is fixedly connected to a gear 33, which meshes with the gear ring 31. When the temperature of the cooling water in the water storage tank 27 cannot be further reduced, the drive motor 32 is started to drive the rotating disk 26 to rotate, and the prepared water storage tank 27 is rotated to the bottom of the round tube 24. The previous water storage tank 27 can be cooled quietly on one side until the cooling water returns to room temperature. The brine in the changing table 25 can also cool the cooling water in the water storage tank 27, which not only saves the waste of cooling water but also allows for quick replacement of cooling water, preventing the concrete 1 from cracking due to the inability to cool down in time.

The outer wall of the inlet pipe 9 is fixedly fitted with a sealing ring 39, and one end of the second liquid pipe 30 extends into the sealing ring 39 and is rotatably connected to the sealing ring 39. The sealing ring 39 can increase the sealing between the second liquid pipe 30 and the inlet pipe 9 when the rotating disk 26 drives the second liquid pipe 30 to rotate. The outlet of the water pump 8 is fixedly fitted with an outlet pipe 10, and the outlet pipe 10 is connected to one end of the cooling pipe 2.

One end of the connecting pipe 13 is fixedly connected to a drain pipe 7. The cooling water in the cooling pipe 2 carries the heat in the concrete 1 to the spiral pipe 12, and the cooling water is initially cooled by the specific heat capacity difference between the brine and the cooling water.

The cooling water that has been initially cooled enters the Tesla valve 6 from the connecting pipe 13. Through the principle of the Tesla valve 6, the flow rate of the cooling water increases, which can increase the flow rate of the water sprayed out from the drain pipe 7, which is used to drive the rotating wheel 19 to rotate, and further cool the cooling water in the later stage.

A rotating wheel 19 is rotatably mounted on the outer wall of the rotating shaft 18. Multiple water receiving plates 20 are bolted to the outer wall of the rotating wheel 19, and the bottom end of the drain pipe 7 is located above one side of the rotating wheel 19. Multiple water-holding cylinders 21 are bolted to the outer wall of the rotating wheel 19. A water inlet tank 22, penetrating the partition 15, is fixedly connected inside the second cavity 17. Activated carbon 43 is fixedly connected to the bottom inner wall of the water inlet tank 22. The end of the water-holding cylinder 21 closest to the water inlet tank 22 is slightly lower than the end furthest from the water inlet tank 22. Cooling water is sprayed through the drain pipe 7 onto the water receiving plate 20 below. The gravity and impact of the water flow not only drive the rotating wheel 19 and the water receiving plate 20 to rotate, but also cause the cooling water to splash as it descends and hits the water receiving plate 20, thus increasing the contact area with the air and quickly dissipating heat into the air. The rotating wheel 19 also drives the water container 21 to rotate, which can stir the cooling water in the second chamber 17 and accelerate the cooling of the cooling water. The water container 21 can collect some cooling water during rotation. As the rotating wheel 19 rotates, when the water container 21 rotates to the top, the cooling water in the water container 21 flows into the water inlet tank 22. The activated carbon 43 can filter impurities in the cooling water to prevent excessive impurities from clogging the cooling pipe 2.

[0057] Reference Figure 4The air-cooled structure 4 also includes a cooling step 23 that is fixedly connected to the first cavity 16 by bolts, and the cooling step 23 is located below the water tank 22. A round pipe 24 is fixedly connected to the bottom inner wall of the first cavity 16 by bolts. The water tank 22 guides the cooling water to the cooling step 23. The cooling water flows on the cooling step 23, increasing the contact area between the cooling water and the air, and dissipating the heat in the cooling water.

[0058] Reference Figure 4 The cooling tank 14 has multiple first conical holes 35 and second conical holes 36 on its opposite sides. The smaller inner diameter ends of the first conical holes 35 and second conical holes 36 are connected to the first cavity 16 and the second cavity 17, respectively. Due to the temperature contained in the cooling water, the heat in the first cavity 16 and the second cavity 17 dissipates upward, resulting in low air pressure in the first cavity 16 and the second cavity 17. At this time, cold air from the outside flows into the first cavity 16 and the second cavity 17 through the first conical holes 35 and the second conical holes 36, respectively. When passing through the first conical holes 35 and the second conical holes 36, the flow rate of the cold air increases. The cold air entering the first conical hole 35 blows towards the cooling step 23, accelerating the dissipation of heat in the cooling water on the cooling step 23. The cold air entering the second conical hole 36 blows upward at an angle, quickly blowing the heat in the second cavity 17 upward. The upward-blown cold air can also provide power for the rotation of the rotating wheel 19 through the water receiving plate 20.

[0059] Reference Figure 4 The cooling box 14 has a through hole 34 located below the cooling step 23. Multiple heat-conducting pipes 37 are fixedly inserted through the cooling box 14 and pass through the second cavity 17. The top inner wall and bottom of the heat-conducting pipes 37 are fixedly connected to baffles 38 by bolts. Because the cooling box 14 has a through hole 34, when outside air enters the through hole 34, it can increase the air flow rate and form wind. At this time, the flowing wind can carry away the heat contained in the cooling water on the cooling step 23, further reducing the temperature of the cooling water. Similarly, the heat of the cooling water in the second cavity 17 can be discharged through the multiple heat-conducting pipes 37. The baffles 38 can make the air in the heat-conducting pipes 37 flow quickly, and the flowing air can carry away the heat in the second cavity 17 through the heat-conducting pipes 37.

[0060] Reference Figure 6The fluid replacement structure 5 includes a replacement platform 25. A rotating disk 26 is rotatably connected to the bottom inner wall of the replacement platform 25. Multiple water storage tanks 27, which cooperate with circular pipes 24, are arranged in a ring on the top of the rotating disk 26, and the water storage tanks 27 are located below the circular pipes 24. A second liquid pipe 30 rotatably passes through the replacement platform 25, and the top end of the second liquid pipe 30 rotatably passes through the rotating disk 26. A first liquid pipe 28, which communicates with the second liquid pipe 30, is bolted to one side of the water storage tanks 27. A valve 29 is fitted on the outer wall of the first liquid pipe 28. A toothed ring 31 is fixedly fitted on the outer wall of the rotating disk 26. A drive motor 3 is bolted to one side of the replacement platform 25. 2. The output shaft of the drive motor 32 extends into the changing table 25 and is fixedly connected to a gear 33, which meshes with the gear ring 31. When the temperature of the cooling water in the water storage tank 27 cannot be further reduced, the drive motor 32 is started to drive the rotating disk 26 to rotate, and the prepared water storage tank 27 is rotated to the bottom of the round tube 24. The previous water storage tank 27 can be cooled quietly on one side until the cooling water returns to room temperature. The brine in the changing table 25 can also cool the cooling water in the water storage tank 27, which not only saves the waste of cooling water but also allows for quick replacement of cooling water, preventing the concrete 1 from cracking due to the inability to cool down in time.

[0061] Reference Figure 8 The bottom of the brine tank 11 is connected to a circulation pipe 40, and the other end of the circulation pipe 40 is connected to the replacement platform 25. A solenoid valve 41 is fitted on the outer wall of the circulation pipe 40. A duct 42 is fixedly connected to the bottom inner wall of the through hole 34, and the duct 42 is located directly above the replacement platform 25. When the brine temperature in the brine tank 11 reaches a certain level and cannot effectively pre-cool the cooling water in the spiral tube 12, the solenoid valve 41 is activated, and the hot brine in the brine tank 11 enters the replacement platform 25 through the circulation pipe 40. The pump (not shown in the figure) pumps the low-temperature brine 8 in the replacement station 25 into the brine tank 11, realizing the exchange of brine. The cooling tank 14 is provided with a through hole 34, so that outside air can quickly pass through the through hole 34. The air entering the through hole 34 can carry away the heat of the cooling water on the cooling step 23. The air in the through hole 34 can also be blown into the replacement station 25 through the air guide pipe 42, so that the brine can be quickly cooled in the replacement station 25. The brine can be recycled to quickly cool the cooling water in the spiral tube 12 and the water storage tank 27.

[0062] Working principle: Cooling water from storage tank 27 is pumped into cooling pipe 2 by water pump 8. The cooling water carries away heat from concrete 1 within cooling pipe 2, lowering its temperature. The cooling water then enters spiral pipe 12. Due to the higher specific heat capacity of water compared to the lower specific heat capacity of brine, brine conducts heat faster. Consequently, the brine in brine tank 11 quickly absorbs the heat from the cooling water in spiral pipe 12, dissipating the absorbed heat into the air. The pre-cooled cooling water then passes through Tesla valve 6. This valve increases the flow rate, and the accelerated cooling water is sprayed through drain pipe 7 onto the receiving plate 20 below. The force of gravity and the impact of the water flow drive the rotating wheel 19 and the receiving plate 20. As the water flows downwards and impacts the receiving plate 20, the rotating wheel 19 causes the cooling water to splash, increasing the contact area with the air and quickly dissipating heat. The rotating wheel 19 also drives the water-holding cylinder 21 to rotate. As the cylinder rotates and enters the cooling water in the second chamber 17, it collects some of the cooling water. As the rotating wheel 19 rotates, the water-holding cylinder 21 rotates upwards, and the cooling water flows into the water inlet tank 22. The activated carbon 43 filters impurities in the cooling water, preventing excessive impurities from clogging the cooling pipe 2. The water inlet tank 22 guides the cooling water to the cooling step 23. The cooling water flows on the cooling step 23, increasing the contact area between the cooling water and the air, thus dissipating heat from the cooling water. Because water contains heat, the heat in the first cavity 16 and the second cavity 17 dissipates upwards, resulting in low air pressure within them. At this time, cold air from the outside flows into the first cavity 16 and the second cavity 17 through the first conical hole 35 and the second conical hole 36, respectively. This increases the airflow velocity. The cold air entering the first conical hole 35 blows towards the cooling step 23, accelerating the dissipation of heat from the cooling water on the cooling step 23. The cold air entering the second conical hole 36 blows upwards at an angle, rapidly pushing the heat in the second cavity 17 upwards. This upward-blown cold air also provides power for the rotation of the rotating wheel 19 through the water receiving plate 20. The first cavity 16... The cooling water inside the tank circulates through the circular pipe 24 into the lower water storage tank 27, enabling self-circulation and cooling. When the temperature of the cooling water in the storage tank 27 cannot be further reduced, the drive motor 32 drives the gear 33, which in turn rotates the rotating disk 26, moving the prepared storage tank 27 below the circular pipe 24. The storage tank 27 then cools quietly to one side until the cooling water returns to room temperature. The brine in the replacement station 25 also cools the cooling water in the storage tank 27. When the temperature of the brine in the brine tank 11 reaches a certain level and can no longer effectively pre-cool the cooling water in the spiral pipe 12, the solenoid valve 41 is activated, and the hot brine in the brine tank 11 enters the replacement station 25 through the circulation pipe 40.The diagram does not show the pump 8 (not shown) that draws the low-temperature brine from the replacement station 25 into the brine tank 11, enabling brine exchange. The cooling tank 14 has a through-hole 34, allowing outside air to quickly pass through and carry away heat from the cooling water on the cooling steps 23. The air in the through-hole 34 can also be blown into the replacement station 25 through the air duct 42, rapidly cooling the brine within the station. This allows for the rapid cooling of the spiral tube 12 and the cooling water in the storage tank 27 using a circulating brine system.
