Description

Concrete cooling water remote control system Technical Field The utility model relates to the technical field of concrete cooling water control, in particular to a concrete cooling water remote control system. Background Practice shows that the temperature control and anti-cracking of the mass concrete water engineering is an important subject in the construction period because the temperature control and anti-cracking of the mass concrete is a complex system engineering problem. Pumping stations, water locks and ship lock engineering are generally known to use pumped concrete casting. Because of the characteristics of high hydration heat and high temperature rise of the pumped concrete, the peak temperature of the concrete hydraulic engineering often exceeds 50 ℃ and even reaches 70 ℃. In order to control the highest temperature of the pouring bin, low-temperature water is usually adopted for water cooling. However, the water cooling is a double-edged sword, on one hand, the casting bin temperature can be quickly reduced by adopting low-temperature water, and on the other hand, if the cooling rate is too high, concrete cracking is still easy to cause. Therefore, the specification of the mass concrete temperature measurement and control technical specification (GB/T51028-2015) prescribes that the difference between the water inlet temperature and the highest temperature of the concrete should be controlled to be 15-25 ℃. As mentioned above, since the peak temperature of the large-volume pumped concrete always exceeds 50 ℃ and even reaches 70 ℃, when water cooling is performed, the water inlet temperature must be timely regulated according to the current measured temperature of the casting bin and the difference (15-25 ℃) between the water inlet temperature and the highest temperature of the concrete, which is specified by the combination of the specifications, for example, when the highest temperature of the concrete is lower than 30 ℃ in the initial stage, the water inlet temperature can be water temperature lower than 15 ℃, and when the highest temperature of the concrete casting bin reaches more than 60 ℃ in the later stage, the water inlet temperature should be water temperature higher than 35 ℃. Practice shows that the self-circulating water is an economic and effective water temperature regulation measure, namely, the water temperature of the water tank is increased by utilizing the heat brought by cooling water along with the temperature rise of hydration heat, so that the difference between the water inlet temperature and the highest temperature of concrete is regulated and controlled to meet the standard requirement. However, when the self-circulating water is adopted for water cooling, the water temperature of the water tank gradually increases, so that the difference between the water inlet temperature and the highest temperature of the concrete gradually decreases, and the cooling effect is lost. Therefore, in order to achieve the optimal cooling effect, the highest temperature, the water inlet temperature and the temperature difference between the highest temperature and the water inlet temperature of the pouring bin are actually measured, and a part of water body of the water tank is replaced by a certain volume of low-temperature water in time, so that the water temperature of the water tank is regulated and controlled. In order to reasonably regulate the water temperature and achieve the aim of preventing concrete from cracking, special people are often required to be arranged for water cooling regulation. Practice shows that when the water temperature of the water tank is manually regulated, time and labor are wasted, especially the water temperature of the water tank is manually regulated in the early morning or at the high Wen Zhengwu at night, and the water temperature of the water tank is inconvenient to regulate on site. Disclosure of Invention The manual control cooling water device aims to solve the problems that the efficiency of manually controlling cooling water of large-volume pumped concrete is low and the workload is large. The utility model provides a concrete cooling water remote control system which comprises a wireless temperature acquisition device for acquiring the temperature inside a pouring bin, a water changing device (water tank) for adjusting the water temperature and a remote control device for controlling water changing. And the water pump in the water changing device is controlled to start and stop in real time by combining the temperature actual measurement value acquired in the large-volume pumping concrete pouring bin, so that the aim of intelligently monitoring the internal temperature of the concrete and remotely regulating and controlling the water supply scheme is fulfilled. The technical scheme adopted by the utility model is as follows: A concrete cooling water remote control system, the system comprising: wireless temperature acquisition device, water c
