Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a large-volume concrete water cooling device and method. Background Art

[0002] Water cooling equipment for curing concrete can ensure that the concrete products do not have cracks and affect the subsequent quality. The water supply needs to be continuous, and the concrete needs to be cured comprehensively to keep the internal humidity and temperature of the concrete in the best state. The Chinese invention patent, authorization announcement number "CN220241838U", discloses a steam curing device for concrete production, including a base plate. On the upper surface of the base plate, there is a steam generating device. The steam generating device includes a steam water tank, a water tank cover plate, two steam heating rods, a connecting rod, a guiding pipe, a power block, a power interface slot, a power interface, a steam pipe and an air outlet hole.

[0003] In the above technical solution, the steam pipe is directly connected from the steam water tank into the storage box, and the position is at the upper part of the storage box, and it can jet air from top to bottom, which can ensure comprehensive curing. However, the above technical solution still has certain defects. When using steam to cure concrete, only the steam is jetted onto the surface of the concrete through the steam pipe and the air outlet hole. Since a large amount of heat is generated during the hydration of cement, due to the large size of the large-volume concrete member, the heat of cement hydration inside is not easily dissipated and will accumulate inside, causing the internal temperature to rise, while the surface temperature is relatively low, forming a temperature gradient. The excessive temperature difference between the inside and outside and the complex temperature stress lead to uneven curing effect and temperature cracks, seriously affecting the safety and performance of the concrete structure. Therefore, the present invention proposes a new solution. Summary of the Invention

At the same time, start the first water pump to pump out the water in the heat absorption pipe and pump it into the heat dissipation pipe. The heat absorption pipe absorbs the heat of the water body in the cooling water tank, is transferred to the heat dissipation pipe through the first water pump and dissipated into the air, realizing the cooling of the water body in the cooling water tank and providing a low-temperature water source for cooling the concrete;

[0024] S2: Internal circulation cooling of concrete: Start the second water pump to pump the water inside the cooling water tank into the water pipe through the water inlet pipe and be shunted to the first connecting pipe and the second connecting pipe through the three-way valve; the first connecting pipe is connected to the first water pipe, the third connecting pipe is connected to the second water pipe, the first water pipe and the four second water pipes are connected end to end and in a spiral shape, and the water inlet end of the first water pipe is located at the center of the concrete; the low-temperature water circulates inside the concrete and takes away the heat generated by the hydration of cement;

[0025] S3: Spraying cooling on the concrete surface: Start the second drive motor to drive the threaded rod to rotate, the threaded rod drives the movable plate to move left and right along the threaded rod and adjusts the position of the, and at the same time start the third drive motor to drive the first gear to rotate, the first gear drives the second gear meshed with it to rotate, so that the water guide pipe and the spray pipe rotate; the water in the second connecting pipe enters the water guide pipe through the rotary joint and is sprayed out from the plurality of nozzles at the lower end of the spray pipe and sprayed onto the surface of the concrete;

[0026] S4: Temperature monitoring and intelligent control: Use four temperature sensors fixed on the concrete surface to monitor the surface temperature in real time and send signals to the external controller and the processor; when the temperature is too high, adjust the pumping speed of the second water pump through the external controller, change the amount of water entering the water pipes inside the concrete, and adjust the cooling intensity; at the same time, control the second drive motor and the third drive motor to adjust the position and rotation speed of the spray pipe to enhance the surface spraying effect;

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The large-volume concrete water cooling device facilitates cooling of the interior of the concrete through the arrangement of the first water pipe and the second water pipe, and the movement and rotation of the nozzle cooperate with each other, which can more comprehensively cover different positions on the concrete surface, expand the spraying range, enhance the cooling effect on the concrete surface, and achieve efficient cooling and maintenance from both the interior and surface levels of the concrete, improve the uniformity of concrete cooling, ensure the quality of concrete, enhance the cooling effect of concrete, and improve the quality of concrete maintenance.

[0031] 2. The large-volume concrete water cooling device, the heat absorption pipe and the heat dissipation pipe work together in the large-volume concrete water cooling device, and are mainly responsible for cooling the water in the cooling water tank and providing a low-temperature water source for concrete cooling. The heat absorption pipe and the heat dissipation pipe are both curled, which increases the contact area with the air to facilitate heat exchange and water cooling, and stabilize the operation of the cooling system.

[0032] 3. The large-volume concrete water cooling device can stir the internal water through rotation. Through stirring, the water temperature in the cooling water tank can be made consistent. During the large-volume concrete water cooling process, if the water temperature in the cooling water tank is uneven and the water temperature in some areas is too high, the cooling effect of the water extracted for cooling the concrete will be uneven. Stirring the water body can avoid this situation, provide a stable and uniform low-temperature water source for concrete cooling, and ensure the stability of the cooling effect.

[0033] 4. The large-volume concrete water cooling device is evenly distributed on the surface of the concrete through the setting of the water guide plate. Due to the large volume of concrete, if the spray water is unevenly distributed, local water accumulation or dryness is likely to occur. The water guide plate can change the direction of water flow so that the water covers all areas of the concrete surface, ensuring that the concrete surface is fully exposed to water, avoiding the problem of insufficient maintenance due to local water shortage, and thus improving the overall maintenance effect.

[0057] A method for water cooling of mass concrete includes the following steps:

[0058] S1: Start the first drive motor 4 to drive the rotation of the rotating shaft 5, so that the rotating shaft 5 drives the spiral stirring blade 6 to stir the water body in the cooling water tank 3, making the water temperature evenly distributed. At the same time, start the first water pump 10 to pump out the water in the heat absorption pipe 7 and pump it into the heat dissipation pipe 9. The heat absorption pipe 7 absorbs the heat of the water body in the cooling water tank 3, transfers it to the heat dissipation pipe 9 through the first water pump 10 and dissipates it into the air, realizing the cooling of the water body in the cooling water tank 3 and providing a low-temperature water source for cooling the concrete.

[0059] S2: Internal circulation cooling of concrete: Start the second water pump 11, pump the water inside the cooling water tank 3 through the water inlet pipe 12 into the water pipe 13, and through the three-way valve, it is split into the first connecting pipe 14 and the second connecting pipe 15; the first connecting pipe 14 is connected to the first water pipe 16, the third connecting pipe 18 is connected to the second water pipe 17, the first water pipe 16 and the four second water pipes 17 are connected end to end and are spiral-shaped, and the water inlet end of the first water pipe 16 is located at the center of the concrete 2; the low-temperature water circulates inside the concrete 2, taking away the heat generated by the hydration of cement.

[0060] S3: Spraying cooling on the concrete surface: Start the second drive motor 26 to drive the rotation of the threaded rod 27, the threaded rod 27 drives the movable plate 29 to move left and right along the threaded rod 27, and adjust the position of 35. At the same time, start the third drive motor 32 to drive the rotation of the first gear 33, the first gear 33 drives the second gear 34 meshing with it to rotate, so that the water guide pipe 31 and the spray pipe 35 rotate; the water in the second connecting pipe 15 enters the water guide pipe 31 through the rotary joint 30 and is sprayed out from the multiple nozzles 36 at the lower end of the spray pipe 35 and sprayed onto the surface of the concrete 2.

[0061] S4: Temperature monitoring and intelligent control: Use the four temperature sensors 19 fixed on the surface of the concrete 2 to monitor the surface temperature in real time and send signals to the external controller and processor; when the temperature is too high, adjust the pumping speed of the second water pump 11 through the external controller, change the water volume entering the water pipes inside the concrete, and adjust the cooling intensity; at the same time, control the second drive motor 26 and the third drive motor 32, adjust the position and rotation speed of the spray pipe 35, and enhance the surface spraying effect.

[0062] S5: Auxiliary curing and structural stability guarantee: Use the water guide plate 20 at the upper end of the concrete 2 to guide the sprayed water to be evenly distributed on the concrete surface, avoid local water accumulation or drying, and improve the curing effect; use the counterweight 24 at the upper end of the fixed plate 23 to balance the weights on the left and right sides of the fixed plate 23, combined with the "T"-shaped first fixing bracket 21, to enhance the structural strength of the device and prevent the components from shaking during operation.

[0063] S6: Post-treatment: When the temperature of the concrete 2 drops to room temperature, disconnect the first connecting pipe 14 from the first water pipe 16 and the third connecting pipe 18 from the second water pipe 17. Drain the water inside the first water pipe 16 and the second water pipe 17, and then inject concrete into the first water pipe 16 and the second water pipe 17, so that the first water pipe 16, the second water pipe 17 and the concrete 2 form an integral whole.

[0064] When using this device, start the first driving motor 4, and its output drives the rotating shaft 5 to rotate, so that the spiral stirring blades 6 on the surface of the rotating shaft 5 rotate in the cooling water tank 3; the spiral stirring blades 6 stir the water body, making the water temperature in the water tank more uniform and avoiding excessive local temperature differences from affecting the cooling effect; at the same time, the first water pump 10 starts to work, pumping out the water pre-stored in the heat absorption pipe 7, pumping the water into the inside of the heat dissipation pipe 9, and circulating the water inside the heat absorption pipe 7 in the heat absorption pipe 7 and the heat dissipation pipe 9; the heat absorption pipe 7 and the heat dissipation pipe 9 are in a coiled shape, increasing the contact area with the air; the heat absorption pipe 7 absorbs the heat of the water body in the cooling water tank 3, and the heat is transferred to the heat dissipation pipe 9 through the first water pump 10 and dissipated into the air at the heat dissipation pipe 9, realizing the cooling of the water body in the cooling water tank 3 and providing a low-temperature water source for cooling the concrete.

[0065] The second water pump 11 is started, pumping water from the cooling water tank 3 through the water inlet pipe 12, and the water is divided into the first connecting pipe 14 and the second connecting pipe 15 through the water outlet pipe 13 and the three-way valve; the first connecting pipe 14 is connected to the first water pipe 16, the third connecting pipe 18 is connected to the second water pipe 17, and the first water pipe 16 and the four second water pipes 17 are connected end to end and in a spiral shape, and the water inlet end of the first water pipe 16 is located at the center of the concrete 2; in this way, the low-temperature water can circulate inside the concrete 2, taking away the heat generated by the hydration of cement, cooling from the inside of the concrete, reducing the internal temperature gradient, and avoiding cracks caused by excessive temperature difference between the inside and the outside.

[0066] The second driving motor 26 is started, and its output drives the threaded rod 27 to rotate; since the movable plate 29 is threadedly sleeved on the threaded rod 27 and slidably connected to the fixed plate 28, the movable plate 29 will move up and down along the threaded rod 27 when the threaded rod 27 rotates, thereby adjusting the height of the spray pipe 35; at the same time, the third driving motor 32 is started, and the first gear 33 at its output drives the second gear 34 meshing with it to rotate, making the water guide pipe 31 and the spray pipe 35 rotate; the water in the second connecting pipe 15 enters the water guide pipe 31 through the rotary joint 30 and then sprays out from the multiple nozzles 36 at the lower end of the spray pipe 35; it is convenient to expand the range of the water sprayed out from the multiple nozzles 36 and facilitate the full cooling of the surface of the concrete 2. The front and rear sides of the spray pipe 35 are turned downwards, which can make the water better spray on the surface of the concrete 2, cool and moisten the surface of the concrete, further assist in reducing the temperature of the concrete, ensure the humidity of the concrete, and improve the curing effect.

[0067] The four temperature sensors 19 on the surface of the concrete 2 monitor the surface temperature of the concrete in real time and send signals to the external controller and processor. When the temperature is too high, the external controller can adjust the pumping speed of the second water pump 11, change the amount of water entering the water pipe inside the concrete, and adjust the cooling intensity. It can also control the second drive motor 26 and the third drive motor 32, adjust the height and rotation speed of the nozzle 35, enhance the surface spraying effect, ensure that the concrete temperature is always in an appropriate range, and ensure the quality of the concrete.

[0068] The water guide plate 20 at the upper end of the concrete 2 can guide the sprayed water to be evenly distributed on the concrete surface, avoiding local water accumulation or drying, allowing the concrete surface to fully contact the water, and improving the maintenance effect; the counterweight block 24 at the upper end of the fixed plate 23 is convenient for balancing the weight on the left and right sides of the fixed plate 23. At the same time, the first fixed bracket 21 is in a "T" shape, which is convenient for improving the structural strength of the device, making the overall structure more stable, and preventing shaking due to the movement of components during operation, ensuring the normal operation of each component, and ensuring the stability and reliability of the water cooling device.

[0069] When the temperature of the concrete 2 drops to room temperature, the first connecting pipe 14 and the first water pipe 16 are disassembled, the third connecting pipe 18 and the second water pipe 17 are disassembled, and the water inside the first water pipe 16 and the second water pipe 17 is pumped out, and then concrete is injected into the first water pipe 16 and the second water pipe 17, so that the first water pipe 16 and the second water pipe 17 and the concrete 2 form a whole.

[0070] Furthermore, by providing the first water pipe 16 and the second water pipe 17, it is convenient to cool the inside of the concrete 2, and the movement and rotation of the nozzle 35 cooperate with each other, which can more comprehensively cover different positions on the surface of the concrete 2, expand the spraying range, enhance the cooling effect on the concrete surface, and achieve efficient cooling and maintenance from both the inside and surface of the concrete, improve the uniformity of cooling of the concrete 2, ensure the quality of the concrete, enhance the cooling effect of the concrete, and improve the quality of concrete maintenance.

[0071] The heat absorbing pipe 7 and the heat dissipating pipe 9 work together in the large-volume concrete water cooling device, and are mainly responsible for cooling the water in the cooling water tank 3, providing a low-temperature water source for concrete cooling. The heat absorbing pipe 7 and the heat dissipating pipe 9 are both curled, which increases the contact area with the air to facilitate heat exchange and water cooling, and stabilize the operation of the cooling system.

[0072] The rotation of 6 facilitates the stirring of the water in 3. By stirring, the water temperature in the cooling water tank can be made uniform. During the water cooling of large-volume concrete, if the water temperature in the cooling water tank is uneven and the water temperature in some areas is too high, the cooling effect of the water extracted for cooling the concrete will be uneven. Stirring the water can avoid this situation, provide a stable and uniform low-temperature water source for concrete cooling, and ensure the stability of the cooling effect.

[0073] Through the setting of the water guide plate 20, it is evenly distributed on the surface of the concrete 2. Since the concrete has a large volume, if the sprayed water is unevenly distributed, local water accumulation or drying is likely to occur. The water guide plate 20 can change the water flow direction, enabling the water to cover all areas of the concrete surface, ensuring that the concrete surface is fully in contact with water, avoiding the problem of insufficient curing caused by local water shortage, and thus improving the overall curing effect.
