Description

Technical Field

[0001] The utility model relates to the technical field of concrete cooling, in particular to a concrete cooling device. Background Art

[0002] In large concrete volumes, the internal temperature of concrete often rises by 10-50°C due to the heat released by cement hydration. The highest temperature reaches 30-70°C. Concrete is a poor conductor of heat, and the natural cooling of concrete is very slow. For large concrete volumes and concrete with large temperature differences between inside and outside, water pipe cooling has become an effective temperature control and crack prevention measure.

[0003] Cooling water pipes are mostly made of steel pipes. The cooling water pipes are buried in concrete. After pouring, the cooling device passes water into the cooling water pipes to absorb heat and lower the internal temperature of the concrete. Then the water flows back into the cooling device. During the water flow, the water generally flows from the head end to the deep end for cooling. In this way, the cooling effect becomes worse the further the water flows, so the cooling efficiency of the concrete at a deep end is low. Therefore, a concrete cooling device is proposed.

The inner ring inner wall of the liquid storage annular cavity 3 is provided with a reflux hole 6 connected with the corresponding reflux cavity 4. The reflux hole 6 is located at one end of the reflux cavity 4 and is provided with a plugging plate B17. The other side of the plugging plate B17 is fixedly connected with a curved elastic plate 18. The other end of the curved elastic plate 18 is fixedly connected with the inner wall of the corresponding reflux cavity 4, so that the water can only flow in the reflux hole 6 to the reflux cavity 4 in one direction, ensuring that the water in the reflux cavity 4 will not flow into the liquid storage annular cavity 3 on the right side. The left and right ends of the head tube 1 and the extension tube 2 are both provided with a through groove 9 connected with the corresponding internal reflux cavity 4. The through groove 9 connects the reflux cavity 4 in the extension tube 2 and the head tube 1.

[0025] The inner annular surfaces of the head pipe 1 and the extension pipe 2 are located on the left side of each liquid filling hole 5 and are fixedly plugged with a guide tube 19, which is coaxially arranged with the head pipe 1 and the extension pipe 2. The guide tube 19 allows the water flow in the head pipe 1 and the extension pipe 2 to pass through the guide tube 19 and enter the liquid storage ring cavity 3 from the liquid filling hole 5.

[0026] The left end inner rings of the head tube 1 and the extension tube 2 are fixedly plugged with an arc-shaped retaining tube 7, and the inner ring sides of the head tube 1 and the extension tube 2 are provided with a plugging disk 8, which contacts the right end of the corresponding arc-shaped retaining tube 7. The inner ring surfaces of the head tube 1 and the extension tube 2 are fixedly connected with a push spring 11, and the left end of the push spring 11 is fixedly connected to the right side surface of the corresponding plugging disk 8.

The number of extension tubes 2 is increased according to the depth of cooling required, so that concrete at different depths can be cooled. Then the plug 12 seals the left end of the leftmost extension tube 2, and the cooling device fills cold water into the head tube 1 and the extension tube 2 through the liquid supply pipe 13. The elastic push plate 16 pushes the plug A15 to seal the filling hole 5, so that the water flows unidirectionally in the filling hole 5. The cooling water is filled from the filling hole 5 into the liquid storage ring cavity 3 to cool the concrete on the outer wall of the head tube 1 and the extension tube 2. The bent elastic plate 18 pushes the plug B17 to seal the reflux hole 6, and the water after absorbing heat flows unidirectionally from the reflux hole 6 to the reflux cavity 4, and the water flows back from the reflux cavity 4 to the reflux pipe 14.
