Description
Technical Field
[0001] The utility model relates to the technical field of concrete pouring, in particular to a large-volume concrete condensing device. Background Art
[0002] Modern buildings often involve large-volume concrete construction, such as high-rise building foundations, large equipment foundations, water conservancy dams, etc. During the construction of large-volume concrete structures, the hydration reaction of cement will generate a large amount of hydration heat. Combined with the particularity of concrete materials, an uneven temperature field will be generated inside the concrete. The external cold concrete is constrained by the expansion and contraction of the internal hot concrete, thus generating temperature stress, which makes it easy for large-volume concrete to produce temperature cracks during the hardening process, reducing the bearing capacity, waterproof performance and durability of large-volume concrete, and affecting the safety and normal use of concrete structures.
[0003] In the prior art, cooling is achieved by installing cooling pipes inside large concrete sinks. This has certain requirements, namely, the relationship between the external temperature and the temperature difference inside the sink. The core temperature should not exceed 60°C, and the maximum should not be greater than 65°C. Watering is prohibited below 5°C. The difference between the core temperature of the concrete and the surface temperature and the ambient temperature should not be greater than 20°C. However, during the condensation process of large-volume concrete, generally, multiple temperature sensors are installed inside the concrete for monitoring, and it is impossible to adjust according to the solidification process of the concrete, which can easily cause the internal temperature of the concrete to be too high or too low, thereby affecting the stability of the large-volume concrete. Therefore, it is necessary to propose a new type of large-volume concrete condensation device. Utility Model Content

The third temperature sensor 503 arranged on the top of the second mounting block 502 measures the flowing cooling water and compares it with the water temperature in the first cache box 401.
[0024] like Figure 1-2 As shown, the outer surface of the first tube body 408 is fixedly connected to the outer surface of the first cache box 401 away from the pump body 407, and the top of the first cache box 401 is fixedly connected with a sealing cover 402, which facilitates the sealing between the sealing cover 402 and the top fixed connection body of the first cache box 401, and facilitates the pump body 407 to transport water in the sealed space and flow into the cooling pipe 2.
[0025] like Figure 1-2 As shown, the first tube body 408 is connected to the pump body 407, and the second tube body 409 is connected to the pump body 407, so that under the action of the pump body 407, external cooling water is drawn through the second tube body 409 and transported to the first cache box 401 through the first tube body 408 for use.
[0026] like Figure 2 As shown, the inner surface of the first cache box 401 is symmetrically fixedly connected with sliding rods 405, and the outer surfaces of the two sliding rods 405 are slidably connected to the inner surface of the baffle 404, so that when the baffle 404 moves, it can slide along the outer surfaces of the two sliding rods 405 to prevent it from shifting during movement and affecting the control accuracy of the water flow.

[0029] The method of use and working principle of the device: When the large-volume concrete condensation device is used, after laying the steel skeleton in the mold 1, an appropriate amount of concrete is injected into it and evenly filled between the steel skeleton and the multiple cooling pipes 2. When heat is generated during the concrete solidification process, multiple first temperature sensors 3 will monitor the internal temperature of the concrete. When the temperature is high, the pump body 407 in the fixed block 406 is started, so that its output end draws external cooling water through the second tube body 409 and transports it to the first cache box 401 through the first tube body 408. The top of the first cache box 401 is fixedly connected with a sealing cover 402 to form a sealed space. At the same time, the second temperature sensor 411 set on the top of the first mounting block 410 will measure the temperature of the cooling water flowing in. The transported water will generate a large pressure inside under the continuous pumping action of the pump body 407 and flow into the corresponding cooling pipe 2. When the cooling water flows in the winding cooling pipe 2, it will absorb the temperature near the cooling pipe 2, which plays a role in cooling and cooling, and flows into the cooling water from the other end of the cooling pipe 2. After being collected in the second cache box 501 and discharged from the third tube body 504, the third temperature sensor 503 arranged on the top of the second mounting block 502 will measure the temperature of the cooling water that absorbs heat again, and compare it with the temperature of the second temperature sensor 411. When the water temperature difference is large, the electric telescopic rod 403 is started, and its telescopic end extends to push the baffle 404 to move, so that it slides along the surface of the two sliding rods 405, gradually blocking the water inlet of the cooling pipe 2, making the water inlet pipe cross-section of the cooling pipe 2 smaller, accelerating the flow speed of the cooling water in the cooling pipe 2, and playing a role of rapid cooling. When the water temperature difference is small, the telescopic end of the electric telescopic rod 403 shrinks to one side of the water inlet of the cooling pipe 2, so that the water flow flows into the cooling pipe 2 more smoothly, reducing the water speed, playing a role of regulation, and facilitating the condensing device to adjust the flow speed of the cooling water according to the temperature difference of the cooling water flowing at the inlet and outlet of the cooling water, so as to adjust the internal temperature of the concrete, avoid excessive or high and low internal temperature of the concrete, and affect the solidification quality of the concrete, thereby improving the stability of large-volume concrete.
