[0003] However, the existing technology mostly adopts a single-point water inlet method. The cooling water will continue to heat up when passing through the interior of the large volume of concrete, resulting in a difference in cooling efficiency between the second half and the first half of the pipeline, thereby increasing the risk of cracking and structural failure of the large volume of concrete.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides a large volume concrete cooling system, which is applied to large volume concrete 6, such as Figure 1-Figure 2 As shown, the mass concrete cooling system comprises:

[0024] Water tank 1 and water pump 2;

[0025] The cooling pipe 3 includes two groups of water inlet pipe sections 31 and water return pipe sections 32. The water inlet pipe sections 31 are connected to both ends of the water return pipe section 32, and a water outlet is provided in the middle of the water return pipe section 32. The water inlet pipe section 31 and the water return pipe section 32 are both arranged inside the mass concrete 6.

[0026] The circulation pipeline includes a first water inlet pipe 41, a second water inlet pipe 42 and a water outlet pipe 43. The first water inlet pipe 41 and the second water inlet pipe 42 are respectively connected to the water inlet pipe section 31. The water outlet pipe 43 is connected to the return pipe section 32 with a water outlet. The end of the water outlet pipe 43 away from the return pipe section 32 leads to the water tank 1. The water pump 2 pumps water from the water tank 1 and sends it to the first water inlet pipe 41 and the second water inlet pipe 42 respectively. The cooling water entering different water inlet pipe sections 31 will be uniformly merged from the return pipe section 32 and then returned to the water tank 1 through the water outlet pipe 43;

[0027] The outlet pipe 43 is also provided with a drain pipe 44, which leads to the wastewater treatment pool. The function of the drain pipe 44 is to timely send out the cooling water that does not meet the requirements in the circulation pipe to avoid the cooling water affecting the heat efficiency exchange;

[0028] In the present application, the mass concrete cooling system further includes a controller 5 and a sensor module, wherein the sensor module includes a first water inlet temperature sensor, a second water inlet temperature sensor, a water pump temperature sensor, a water tank temperature sensor, a first water outlet temperature sensor, a second water outlet temperature sensor and a surface temperature sensor 7. The controller 5 senses the temperature values ​​of different modules during the cooling process through the sensor module, so that the operator can adjust the water circulation structure according to the temperature change. The controller 5 uses existing technical equipment to control the corresponding valve equipment as needed.

[0029] As a preferred implementation in this embodiment, a main water inlet pipe is further provided at the front end of the first water inlet pipe 41 and the second water inlet pipe 42, one end of the main water inlet pipe is connected to the outlet of the water pump 2, and a three-way water diverter valve is provided at one end of the main water inlet pipe away from the outlet of the water pump 2, and the other two ports of the three-way water diverter valve are respectively connected to the first water inlet pipe 41 and the second water inlet pipe 42;

[0030] In this embodiment, the water diverter valve controls the amount of water distributed from the main water inlet pipe to different first water inlet pipes 41 and second water inlet pipes 42. Since the two groups of water inlet pipe sections 31 are respectively connected to both sides of the return water pipe section 32, different water inlet pipe sections 31 will form different cooling areas with the return water pipe section 32. Here, different cooling areas are defined as the first cooling area and the second cooling area, respectively. The cooling water sent by the first water inlet pipe 41 and the second water inlet pipe 42 will flow through different cooling areas. This has the advantage of allowing the initial cooling water to contact more areas, avoiding the initial cooling water from always contacting a fixed area during the cooling process, resulting in differences in cooling rates between different areas.

[0031] In addition, the present application also utilizes the cooperation between the first water inlet temperature sensor, the second water inlet temperature sensor, the first water outlet temperature sensor and the second water outlet temperature sensor. The first water inlet temperature sensor and the second water inlet temperature sensor respectively detect the water temperatures in the first water inlet pipe 41 and the second water inlet pipe 42, and the first water outlet temperature sensor and the second water outlet temperature sensor monitor the temperatures on both sides of the water outlet of the return water pipe section 32. The water temperatures on both sides of the water outlet of the return water pipe section 32 are actually the temperatures of the cooling water returned after flowing through different cooling areas. The cooling effects of different cooling areas can be judged by comparing the temperature difference between the first water inlet temperature sensor and the first water outlet temperature sensor and the temperature difference between the second water inlet temperature sensor and the second water outlet temperature sensor. Here, the greater the temperature difference, the greater the heat in the area, and more water needs to be invested to enhance the cooling effect of the area. The water diversion valve is used to adjust the water volume relationship between different cooling areas. The water diversion valve here adopts the existing mature three-way regulating valve structure.

[0032] As a preferred implementation in this embodiment, the water pump temperature sensor, water tank temperature sensor and surface temperature sensor 7 respectively test the surface temperatures of the water pump 2, water tank 1 and mass concrete 6, and the operator adjusts the circulation power of the water pump 2 according to the temperature feedback;

[0033] As a preferred implementation in this embodiment, a three-way valve is provided at the connection between the outlet pipe 43 and the drain pipe 44. The three-way valve is pneumatically controlled. When the water temperature in the water tank rises to a certain level, the three-way valve changes the passage state, allowing the cooling water returned by the outlet pipe 43 to be directly sent to the wastewater treatment tank through the drain pipe 44, while the synchronous water tank 1 is replenished with water through a replenishing pump, so as to avoid the failure to achieve the cooling effect due to the increase in water temperature during the circulating cooling process. By setting a drain port on the outlet pipe 43, the returned high-temperature cooling water can be released in advance, so as to avoid the mixing of the high-temperature cooling water returning to the water tank with the newly replenished cooling water to affect the replenishment efficiency. The advantage of this is that the high-temperature cooling water is released in advance, so that the high-temperature cooling water will not be mixed with the low-temperature cooling water during replenishment, thereby reducing the heat exchange process and improving the replenishment efficiency.
