[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0026] See also Figures 1 to 5The utility model provides a technical solution: a pre-buried cooling device for preventing cracking of thick-walled concrete, comprising: a water pipe 2, which is pre-buried in a concrete wall 1 in a spiral shape, and both ends of the water pipe 2 are located on the outside of the concrete wall 1. The upper end of the water pipe 2 is connected to an external circulating water pool through a water pump, and the lower end of the water pipe 2 is connected to an external circulating water pool through a connecting pipe. When the water pump is started, water flow is always maintained in the water pipe 2 to take away the heat inside the concrete.

[0027] Support components are provided on both sides of the lower end of the water pipe 2, and lifting components are provided on both sides of the upper end of the water pipe 2. Before pouring concrete, the water pipe 2 is first placed in the template for pouring concrete. The water pipe 2 is fixed in the template by the support components and the lifting components, and then concrete is poured into the template.

[0028] A cooling component is detachably mounted on the outer wall of the water pipe 2, and the cooling component includes an arc-shaped heat conducting plate 11 and an arc-shaped heat conducting plate 2 12, and the arc-shaped heat conducting plate 11 and the arc-shaped heat conducting plate 2 12 are fixedly mounted on the outer wall of the water pipe 2 through a clamp 15, and a plurality of heat dissipation strips 14 are evenly fixedly mounted on the outer walls of the arc-shaped heat conducting plate 11 and the arc-shaped heat conducting plate 2 12, and the heat dissipation strips 14 are conical, and the outer walls of the left and right ends of the arc-shaped heat conducting plate 11 and the arc-shaped heat conducting plate 2 12 are provided with fixing grooves 13, and the clamps 15 are located in the fixing grooves 13, and the two adjacent clamps 15 are fixed by bolts 16, so as to fix the arc-shaped heat conducting plate 11 and the arc-shaped heat conducting plate 2 The arc-shaped heat conducting plate 12 is fixed on the outer wall of the water pipe 2, and the heat dissipation strip 14 is made of heat-conducting metal. The width of the heat dissipation strip 14 gradually decreases. As the heat dissipation strip 14 moves away from the arc-shaped heat conducting plate 1 11 and the arc-shaped heat conducting plate 2 12, the heat conductivity of the heat dissipation strip 14 becomes weaker and weaker. The heat dissipation strip 14 is set in a cone shape, which can reduce the volume of the heat dissipation strip 14 without affecting the inner wall structure of the concrete, and can also cool the inside of the concrete well. When water flows through the water pipe 2, the water pipe 2, the arc-shaped heat conducting plate 1 11, the arc-shaped heat conducting plate 2 12 and the heat dissipation strip 14 take away the heat inside the concrete and cool the inside of the concrete.

[0029] The supporting component includes a heat-conducting ring 3, which is sleeved on the outer wall of the water pipe 2. A heat-conducting vertical plate 4 is fixedly installed on the lower end of the heat-conducting ring 3, and a heat-conducting bottom plate 5 is fixedly installed on the lower end of the heat-conducting vertical plate 4. The heat-conducting vertical plate 4 is in a flat triangular shape, and a number of through holes are evenly opened on the side walls of the heat-conducting vertical plate 4. The through holes can allow the concrete to ventilate. The heat-conducting bottom plate 5 and the heat-conducting vertical plate 4 support the water pipe 2 inside the template. At the same time, the heat-conducting ring 3, the heat-conducting vertical plate 4 and the heat-conducting bottom plate 5 can also transfer the heat inside the concrete to the water pipe 2, and exchange heat with the cold water in the water pipe 2.

[0030] The hanging parts include a heat-conducting ring 6, which is sleeved on the outer wall of the water pipe 2. A heat-conducting connecting rod 7 is fixedly installed on the upper end of the heat-conducting ring 6. A heat-conducting connecting plate 8 is fixedly installed on the upper end of the heat-conducting connecting rod 7. Through holes are evenly arranged on the side walls of the heat-conducting connecting plate 8, and the through holes can allow the concrete to be ventilated. Iron wires 9 are fixedly installed on the front and rear sides of the upper end of the heat-conducting connecting plate 8. A support rod 10 is fixedly connected to the upper end of the iron wire 9. The front and rear ends of the support rod 10 are overlapped on the upper end of the template to fix the upper end of the water pipe 2 to prevent the water pipe 2 from tilting. At the same time, the heat-conducting ring 6, the heat-conducting connecting rod 7, the heat-conducting connecting plate 8 and the iron wire 9 can also transfer the heat inside the concrete to the water pipe 2 to exchange heat with the cold water in the water pipe 2.

[0031] When the device is working, the water pipe 2 is first installed in the template through the supporting components and the hanging components, and then concrete is poured in the template. After the concrete is formed, the iron wire 9 exposed at the upper end is cut off, and the water pipe 2 is pre-buried in the concrete. Then, the upper end of the water pipe 2 is connected to the external circulating water pool through a water pump, and the lower end of the water pipe 2 is connected to the external circulating water pool through a connecting pipe. When the water pump is started, water flow is always maintained in the water pipe 2, and the cooling components, supporting components and hanging components exchange heat with the cold water in the water pipe 2 and the concrete, thereby taking away the heat inside the concrete.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
