Description

Technical Field

[0001] The utility model mainly relates to the technical field of temperature reduction devices, in particular to a cooling circulation device. Background Art

[0002] At present, controlling the temperature difference between the inside and outside of concrete is generally divided into two stages: before pouring and after pouring. The first stage is to control the adiabatic temperature rise and mold temperature of concrete by optimizing the concrete mix ratio and lowering the mixing temperature; the second stage is to control the temperature of concrete after pouring, especially the temperature during the curing period when the concrete strength has not yet been formed, because this stage is also the period of crack generation and development. It can be seen that temperature control in the second stage is more important for preventing harmful cracks. The mainstream international engineering community believes that the most effective active technology for controlling the temperature of large-volume concrete in the second stage is to introduce cooling circulating water for cooling.

[0003] In the prior art, a patent with the authorization announcement number CN 212453720 U discloses an automatic circulating cooling and temperature reduction device for large-volume concrete. The device can open or close the circulating cooling water in real time according to the temperature difference between the inside and outside of the large-volume concrete component, reduce energy consumption, and control the temperature difference between the cooling water and the internal temperature of the large-volume concrete component to not exceed 20°C. The operation is simple and convenient, and no manual control is required. However, the device is provided with a circulating water pipe pre-buried inside the large-volume concrete component. The circulating water pipe is arranged in a circuitous manner in the large-volume concrete component, which can achieve a good heat exchange efficiency. However, after the concrete component is cured and formed, the residual water in the circuitous circulating water pipe is not easy to be completely discharged, and the circuitous circulating water pipe is difficult to remove, and it is not easy to be sealed with cement slurry, resulting in adverse effects on the strength and other properties of the large-volume concrete component containing the circulating water pipe. Therefore, it is necessary to provide a cooling circulation device including a cooling pipe that is easy to remove or grout and seal. Utility Model Content

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a cooling circulation device to solve the technical problem that the cooling pipe is not easy to remove or grout and seal mentioned in the above background technology.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A cooling circulation device comprises a cooling pipe located inside a concrete component and a water circulation mechanism located outside the concrete component and connected to the cooling pipe; the cooling pipe is a straight pipe, and a plurality of the cooling pipes are arranged in parallel with each other, the same end of all the cooling pipes is connected to a water inlet pipe, and the other ends of all the cooling pipes are connected to a drain pipe.

[0007] Furthermore, both ends of the cooling pipe are detachably connected with connecting pipes.

[0008] Furthermore, one end of the connecting pipe is provided with a connecting portion for inserting the cooling pipe.

[0009] Furthermore, the connecting portion is threadedly connected to the cooling pipe, inner walls at both ends of the cooling pipe are provided with internal threads, and a sealed bearing is provided at one end of the connecting pipe facing away from the cooling pipe.

[0010] Furthermore, a temperature sensing element is provided in the cooling pipe and is arranged close to the wall.

[0011] Furthermore, the cooling pipe is arranged horizontally, the water inlet pipe is located on the upper end side of the concrete component, and the drainage pipe is located on the lower end side of the concrete component.

[0012] Furthermore, a water distributor for evenly distributing water to all cooling pipes is provided at the output end of the water inlet pipe.

[0013] Furthermore, the cooling pipe includes a straight pipe and two sections of spliced ​​pipes located inside the straight pipe, the inner wall of the spliced ​​pipe is provided with threads; the spliced ​​sides of the two sections of the spliced ​​pipes are both shrunken to form a reduced diameter portion, the temperature sensing element is installed on the outer surface of the reduced diameter portion of one section of the spliced ​​pipe, and a cavity is formed between the reduced diameter portions of the two sections of the spliced ​​pipes and the straight pipe after splicing, the temperature sensing element is located in the cavity and close to the inner wall of the straight pipe, and a strip groove is provided on the inner wall of the straight pipe for leading out the wire of the temperature sensing element.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The cooling pipes in the present invention are multiple straight pipes arranged in parallel. They are uniformly pre-buried in the concrete component, and the two ends of all the cooling pipes are respectively connected to the water inlet pipe and the drainage pipe. Water flows through the cooling pipes, which can effectively cool the inside of the concrete component. After the concrete component is cured and formed, the pipe fittings on both ends of the cooling pipes can be removed to expose the two ends of the cooling pipes. Since the cooling pipes are straight pipes, the residual water in the cooling pipes can be easily discharged completely. It is also convenient to remove or grout the cooling pipes, thereby avoiding the cooling pipes affecting the strength and other properties of the large-volume concrete component.

[0016] (2) In the optimized solution of the present invention, a temperature sensing element is arranged inside the cooling pipe, and the temperature sensing element is arranged close to the inner wall of the cooling pipe, which can effectively detect the internal temperature of the concrete component, so as to determine the internal and external temperature difference of the concrete component by comparing the surface temperature of the concrete component, thereby facilitating the supply control of the cooling water body; and after the concrete component is cured and formed, the pipe fittings at both ends of the cooling pipe are removed so that the two ends of the cooling pipe are exposed, and the temperature sensing element can also be removed more conveniently.

[0017] (3) In the optimized solution of the utility model, the cooling pipe is set as a straight pipe and two sections of spliced ​​pipes located inside the straight pipe. The inner wall of the spliced ​​pipe is provided with threads. The protruding part of the threads can slow down the rapid flow of water, so that the water entering the cooling pipe forms a vortex and flows down more slowly, thereby having more time to cool the concrete component. After the concrete component is cured and formed, after the pipe fittings on both ends of the cooling pipe are removed, the spliced ​​pipe can be easily removed from the straight pipe for recycling; then cement slurry can be poured into the straight pipe with a smooth inner wall to ensure the strength and other properties of the concrete component, and the straight pipe can also be removed.

[0018] (4) In the optimized solution of the utility model, the spliced ​​pipe is divided into two spliced ​​sections, and the splicing sides of the two sections of the spliced ​​pipe are both shrunken to form a reduced diameter portion. After the reduced diameter portions of the two sections of the spliced ​​pipe are spliced ​​together, a cavity for placing a temperature sensing element is formed between the straight pipe. After such an arrangement, the temperature sensing element can effectively detect the temperature and prevent the temperature sensing element from contacting the coolant. When in use, when the spliced ​​pipe is extended into the straight pipe, it can drive the temperature sensing element to move into place. When the spliced ​​pipe is pulled out of the straight pipe, it can drive the temperature sensing element to move out of the straight pipe, which is convenient for use.
