Description

Technical Field

[0001] This utility model relates to a concrete cooling device, and more particularly to a large-volume concrete adaptive circulating water cooling device applied in the field of cooling devices. Background Technology

[0002] The concrete adaptive circulating water cooling device is an intelligent temperature control system mainly used to regulate the internal temperature of large-volume concrete during construction, preventing structural cracks caused by hydration heat. Its core principle is to monitor the internal temperature of the concrete in real time through pre-embedded temperature sensors, and then dynamically adjust the cooling water flow rate and velocity in conjunction with the circulating water pump and cooling water pipeline network to achieve precise temperature difference control.

[0003] Chinese patent CN221989326U discloses a concrete cooling pipe structure, belonging to the field of concrete structure engineering technology. This structure includes a concrete structure and a cooling pipe. The outer wall of the cooling pipe has an uneven structure, so that the contact area between the cooling pipe and the concrete is no longer a smooth surface. This uneven structure increases the friction between the cooling pipe and the concrete, thereby enhancing the contact strength and facilitating coordinated deformation of the cooling pipe and concrete. This reduces the risk of micro-cracks forming at the contact point, ensuring the overall safety of the concrete structure.

[0004] Chinese patent CN216341081U discloses a deformation-resistant cooling pipe suitable for cooling large volumes of concrete. It consists of a cast iron cooling pipe with a connecting rod and an anti-shrinkage disc of the same material fixed to its outer circumference via a heat-melting point. The anti-shrinkage disc and connecting rod are a single integral component. This cooling pipe facilitates the post-construction pressure grouting of the concrete cooling pipe with the same grade of mortar and the removal of air content from the mortar during vacuuming. The anti-shrinkage disc provides a reaction force, and the connecting rod transmits force, effectively preventing the cooling pipe from shrinking during vacuuming.

[0005] However, the adaptive circulating water cooling device for large-volume concrete lacks targeted surface temperature regulation methods and relies solely on natural heat dissipation or single insulation measures, making it difficult to balance the internal and external temperature differences. Especially during winter construction or in high-temperature environments, the surface and internal temperature differences fluctuate drastically, and a large amount of waste heat generated during the cooling process is not utilized, which wastes energy and does not meet the requirements of green construction. Utility Model Content

[0006] The technical problem that this utility model aims to solve in response to the above-mentioned prior art is that the adaptive circulating water cooling device for large-volume concrete lacks targeted means of surface temperature regulation. Relying solely on natural heat dissipation or a single insulation measure makes it difficult to balance the internal and external temperature differences. Especially during winter construction or in high-temperature environments, the surface and internal temperature differences fluctuate drastically, and a large amount of residual heat generated during the cooling process is not utilized, which wastes energy and does not meet the requirements of green construction.

[0007] To address the aforementioned problems, this utility model provides a large-volume concrete adaptive circulating water cooling device, comprising a circulating cooling component, an auxiliary heat exchange component fixedly connected to the outer side of the circulating cooling component, and an emergency backup component fixedly connected inside the circulating cooling component. The circulating cooling component includes a concrete body, with multiple sets of serpentine circulating water cooling pipes installed at the inner end of the concrete body. A valve is fixedly connected to the inlet of the serpentine circulating water cooling pipe, and a valve is fixedly connected to the outlet of the serpentine circulating water cooling pipe. A circulating pump is connected to both valves. The auxiliary heat exchange component includes a heat exchanger body, with multiple sets of serpentine circulating water cooling pipes extending into the heat exchanger body. A cold water injection pipe is fixedly connected to the end of the heat exchanger body away from the concrete body, and a warm water output pipe is fixedly connected to the end of the heat exchanger body closer to the concrete body. Multiple side auxiliary supports are threadedly installed at the outer end of the concrete body, and a transverse hollow tube is fixedly connected between the left and right inner walls of the side auxiliary supports. Multiple atomizing electric spray nozzles are fixedly connected to the end of the transverse hollow tube closer to the concrete body.

[0008] In the aforementioned large-volume concrete adaptive circulating water cooling device, summarize the overall solution and its effects in one sentence. As a further improvement of this application, the outlet angles of the multiple atomizing electric spray nozzles are staggered, and the outlets of the multiple atomizing electric spray nozzles correspond to the concrete surface.

[0009] As a further improvement of this application, multiple mounting holes are fixedly connected to both the serpentine circulating water cooling pipe and the concrete body, and a temperature sensor is fixedly connected to the inner end of each mounting hole.

[0010] As a further improvement of this application, multiple transverse hollow tubes are interconnected and connected to a warm water output pipe, and the emergency backup component includes a backup branch pipe.

[0011] As another improvement of this application, the connection of the serpentine circulating water cooling pipe is provided with multiple bends, and the spare branch pipe is fixedly connected to the side of the bend in the serpentine circulating water cooling pipe.

[0012] As a further improvement to this application, each end of the spare branch pipe is fixedly connected to an electric valve, and the two electric valves are respectively connected to the serpentine circulating water cooling pipe.

[0013] As a further improvement to this application, two electric valves are fixedly connected to both ends of the bent connection, and the two electric valves are respectively connected to the serpentine circulating water cooling pipe.

[0014] In summary, this design employs a multi-zone arrangement of serpentine circulating water-cooled pipes to ensure uniform cooling across all areas of the concrete structure. Temperature sensors monitor the temperature difference in real time, and the control system dynamically adjusts the water flow rate based on this difference. Combined with surface temperature adjustment of the auxiliary heat exchange components, the auxiliary heat exchange components recover waste heat from the serpentine circulating water-cooled pipes through the heat exchanger body. This heat is then delivered to the atomizing electro-hydraulic spray nozzle via the warm water output pipe and the transverse hollow pipe. The atomized warm water is then applied to the concrete surface, reducing heat waste and lowering the energy consumption of individually controlling the surface temperature, thus conforming to green construction principles. When blockages or damage occur at the bends or connections of the serpentine circulating water-cooled pipes, the emergency backup component can close the faulty section via electro-hydraulic valve two and open the backup branch pipe via electro-hydraulic valve one. Combined with dynamic flow rate adjustment, this ensures uninterrupted cooling circulation and prevents temperature runaway due to localized faults, significantly improving the stability of the device under complex operating conditions.

[0017] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] First implementation method: Figures 1-6 This invention illustrates an adaptive circulating water cooling device for large-volume concrete, comprising a circulating cooling component 1, an auxiliary heat exchange component 2 fixedly connected to the outside of the circulating cooling component 1, and an emergency backup component 3 fixedly connected inside the circulating cooling component 1. The circulating cooling component 1 includes a concrete body 100, with multiple sets of serpentine circulating water cooling pipes 102 installed at the inner end of the concrete body 100. A valve 104 is fixedly connected to the inlet of each serpentine circulating water cooling pipe 102, and a valve 105 is fixedly connected to the outlet of each serpentine circulating water cooling pipe 102. A circulating pump, optionally an ISG80-160 type vertical pipeline centrifugal pump, is connected to both valves 105 and 104. The auxiliary heat exchange component 2 includes a heat exchanger body 20. 0. Multiple sets of serpentine circulating water cooling pipes 102 extend into the heat exchanger body 200. Plate heat exchangers can be used. A cold water injection pipe 201 is fixedly connected to the end of the heat exchanger body 200 away from the concrete body 100, and a warm water output pipe 202 is fixedly connected to the end of the heat exchanger body 200 close to the concrete body 100. Multiple side auxiliary supports 203 are threadedly installed on the outer end of the concrete body 100. A transverse hollow pipe 204 is fixedly connected between the left and right inner walls of the side auxiliary supports 203. Multiple atomizing electric spray nozzles 205 are fixedly connected to the end of the transverse hollow pipe 204 close to the concrete body 100 to ensure full coverage of the concrete surface. The model can be SUS304-1 / 4PT.

[0019] The outlet angles of multiple atomizing electric spray nozzles 205 are staggered, and the outlets of the multiple atomizing electric spray nozzles 205 correspond to the surface of the concrete body 100. Multiple mounting holes 103 are fixedly connected to the outside of the serpentine circulating water cooling pipe 102 and the concrete body 100, respectively. A temperature sensor 1031 (model WZP-230) is fixedly connected to the inner end of the mounting hole 103. Multiple transverse hollow pipes 204 are interconnected and connected to the warm water output pipe 202. Figures 1-6This diagram illustrates that when the device is started, multiple sets of serpentine circulating water-cooling pipes 102 inside the concrete body 100 in the circulating cooling assembly 1 are connected to an external circulating pump via valve 104. Cold water enters the serpentine circulating water-cooling pipes 102 through valve 104. The multiple sets of serpentine circulating water-cooling pipes 102 are arranged with a spacing of 0.8m × 0.8m to ensure uniform cooling. During the flow process, the water absorbs the heat of hydration released by the concrete body 100. The heated water flows back to the circulating pump through valve 2 105, forming a basic cooling cycle. The temperature sensor 1031 inside the mounting hole 103 monitors the temperature inside the concrete body 100 and the surface temperature of the serpentine circulating water-cooling pipes 102 in real time. The data is fed back to the control system. The control system receives the signal from the temperature sensor 1031 and dynamically adjusts the power of the circulating pump to change the water flow rate of the serpentine circulating water cooling pipe 102. This serves as the basis for flow rate adjustment. When the temperature sensor 1031 of a certain area and layer detects that the temperature difference between the inside and outside of the concrete 100 reaches 12℃, the control system receives the feedback data and automatically adjusts the water flow rate of the corresponding serpentine circulating water cooling pipe 102 in that area and layer, increasing it from the initial 1.0 m / s to 1.2 m / s to enhance the cooling effect. As the heat of hydration of the concrete is released, if the temperature difference between the inside and outside of that area and layer further rises to 14℃, the control system adjusts the water flow rate again. The flow rate is increased to 1.5 m / s. The auxiliary heat exchange component 2 operates in conjunction with the circulating cooling component 1. The heat exchanger body 200 is traversed through the circulation path of the serpentine circulating water cooling pipe 102. Cold water is injected into the heat exchanger body 200 via the cold water injection pipe 201 for heat exchange. The cooled water continues to circulate back along the serpentine circulating water cooling pipe 102. The warm water generated during heat exchange is transported to the transverse hollow pipe 204 via the warm water output pipe 202. The transverse hollow pipe 204 is fixed to the outside of the concrete body 100 via the side auxiliary support 203. The warm water is finally atomized and sprayed onto the surface of the concrete body 100 through the atomizing electric spray nozzle 205, utilizing residual heat to regulate the surface temperature and prevent internal and external heat exchange. Excessive temperature difference keeps the internal and external temperature difference within 15℃. The auxiliary heat exchange component 2 recovers the waste heat in the serpentine circulating water cooling pipe 102 through the heat exchanger body 200, and delivers it to the atomizing electric spray nozzle 205 through the warm water output pipe 202 and the transverse hollow pipe 204. The warm water is then atomized and applied to the surface of the concrete body 100. This reduces heat waste and lowers the energy consumption of individually controlling the surface temperature during winter construction. By recycling energy, the external energy input is reduced. The control system activates the atomizing electric spray nozzle 205 to increase the surface temperature in winter based on the data from the temperature sensor 103. In high-temperature environments, the spray is turned off and the water flow rate is increased to reduce the surface temperature.

[0020] Second implementation method: Figure 2 , Figure 7This invention discloses an adaptive circulating water cooling device for large-volume concrete. The emergency backup component 3 includes a backup branch pipe 300. Multiple bends 1020 are provided at the connection points of the serpentine circulating water cooling pipe 102. The backup branch pipe 300 is fixedly connected to the side of the bends 1020 in the serpentine circulating water cooling pipe 102. Two electric valves 301 are fixedly connected to both ends of the backup branch pipe 300, and are respectively connected to the serpentine circulating water cooling pipe 102. Two electric valves 302 are fixedly connected to both ends of the bends 1020, and are respectively connected to the serpentine circulating water cooling pipe 102. The types of valves can be selected from various models. The electric ball valve is Q911F-16P. When the bend connection 1020 of the serpentine circulating water cooling pipe 102 becomes blocked or damaged, the emergency backup component 3 can be activated as an optional accessory. The control system closes the second electric valve 302 at both ends of the bend connection 1020 and opens the first electric valve 301 at both ends of the backup branch pipe 300, allowing water to flow through the backup branch pipe 300 to bypass the faulty section, ensuring that the cooling circulation is uninterrupted. The temperature sensor 1031 continuously monitors the temperature of the faulty area. If the temperature difference approaches the threshold, the control system automatically adjusts the power of the circulating pump and changes the water flow rate of the serpentine circulating water cooling pipe 102 and the backup branch pipe 300, ensuring the quality of concrete construction.

[0021] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
