The system includes a U-shaped cooling pipe installed on a reinforcing steel frame, and a water storage tank and a return water tank respectively fixed to the ground. A flow pipe connects the water storage tank and the return water tank. The system also includes a circulating water pump installed on the ground.

This increases the heat exchange area, resulting in a cooling effect far superior to localized water columns or droplets.

Description

Technical Field

[0001] This invention relates to the field of concrete structure crack prevention technology, specifically to a built-in circulating cooling pipe network system for ultra-heavy concrete structures. Background Technology

[0002] As a primary engineering material, the quality of concrete directly impacts the safety of buildings. Concrete used in hydraulic structures that are frequently or periodically subjected to environmental water is called hydraulic concrete. Unlike concrete used in industrial and civil buildings, hydraulic concrete, in addition to meeting strength requirements, must also meet specific requirements for impermeability, frost resistance, crack resistance, erosion resistance, wear resistance, and corrosion resistance, depending on its location and working conditions.

[0003] To control the temperature difference between the inside and outside of large-volume concrete during construction, certain temperature control measures must be taken, and pre-embedded cooling water pipes for water cooling are the most common measures. Cooling water can be divided into non-circulating water and internal circulating water according to the utilization method of the water source. When internal circulating water is used, the cooling water pipes are installed on the steel reinforcement frame. During concrete pouring, as the concrete heats up, the temperature of the circulating water rises. After being discharged into the circulating water tank, the temperature of the cooling water in the tank does not drop easily, thus affecting the subsequent cooling effect on the concrete. Summary of the Invention

[0004] The purpose of this invention is to provide a built-in circulating cooling pipe network system for ultra-heavy concrete structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a built-in circulating cooling pipe network system device for ultra-heavy concrete structures, comprising a U-shaped cooling pipe installed on a steel frame and a water storage tank and a return water tank respectively fixed on the ground, wherein a flow pipe connects the water storage tank and the return water tank, and further comprising; A circulating water pump installed on the ground, wherein the suction end of the circulating water pump is connected to a water storage tank, the discharge end of the circulating water pump is connected to one end of a U-shaped cooling pipe, the other end of the U-shaped cooling pipe is connected to a drain pipe, and the other end of the drain pipe passes through the return water tank and extends into its interior. A swinging component is installed at the other end of the drain pipe, and the drain pipe achieves the rotation and spraying of the swinging component through the discharge force of the water flow; The heat dissipation section installed inside the U-shaped cooling pipe achieves cooling of the tank body and the circulating water through the rotation of the blades in the heat dissipation section.

[0006] Preferably, the oscillating element includes: A swing tube is rotatably connected to the inside of the other end of a drain pipe, and a fixed plate is fixedly connected to the inside of one end of the swing tube. A fixing rod is fixed to the top of the fixing plate, and an impeller that rotates by the impact of water flow is fixed to the top of the fixing rod.

[0007] Preferably, the heat dissipation unit includes: A stepper motor is fixed on the dustproof frame on the top of the return water tank. The output end of the stepper motor is fixed with a rotating rod, and the top of the rotating rod is fixed with a fan blade located above the drain pipe. An agitator located at the bottom of the inner cavity of the return water tank, which can agitate the circulating water by rotating. The transmission component is located on the outside of the return water tank and drives the agitator to rotate through the rotation of the fan blades.

[0008] Preferably, the stirring component includes: A movable rod is rotatably connected to the bottom of the inner cavity of the return water tank and has protrusions on its outer perimeter. A movable block adapted to the surface of the movable rod is slidably connected to the surface of the movable rod. A stirring rod, which is several in number and fixed around the surface of the movable block; A connecting rod is fixed around the top of the movable block, and the upper and lower movable blocks are fixed together by the connecting rod. A movable ring is fixed to the top of the uppermost connecting rod.

[0009] Preferably, the transmission component includes: The system consists of two meshing bevel gear sets, namely, Bevel Gear Set 1 and Bevel Gear Set 2. The large bevel tooth of Bevel Gear Set 1 is fixed to the bottom of the fan blade, and a transmission rod 1 is fixed to one side of the small bevel tooth. One bevel tooth of Bevel Gear Set 2 is fixed to the surface of the movable rod. A reducer is fixed to the outside of the return water tank. The other end of the transmission rod is fixed to the shaft of the reducer. The other shaft of the reducer is fixed with a synchronous pulley. The synchronous pulley is connected to a synchronous pulley two via a synchronous belt. One end of the transmission rod is fixed to one side of the synchronous wheel two, and the other end of the synchronous wheel two extends into the interior of the return water tank and is fixed to another bevel gear of the bevel gear two.

[0010] Preferably, the heat dissipation part further includes a movable component, the movable component comprising: A half gear is fixed to one surface of a transmission rod, and the surface of the half gear is meshed with a toothed frame that moves up and down as it rotates. The connecting plate has a folded structure and one end is fixed to the bottom end of the toothed frame, while the other end of the connecting plate is rotatably connected to the movable ring.

[0011] Preferably, a T-shaped groove is provided on one side of the connecting plate, and the interior of the T-shaped groove is slidably connected to a fixing block on the inner wall of the return water tank.

[0012] Preferably, the outer surface of the return water tank is provided with a number of heat dissipation fins, and the heat dissipation fins are arranged at equal intervals.

[0013] Preferably, a filter screen is installed at the connection point between the flow pipe and the return water tank.

[0014] Preferably, the surface of the return water tank is provided with a plurality of heat dissipation holes, the heat dissipation holes are located above the fan blades, and a temperature detector is installed on the inner wall of the return water tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When circulating water is discharged into the return water tank through the drain pipe, the water source exerts force on the impeller and drives the fixed rod and swing tube to rotate. This allows the cooling water to diffuse and spray out through the swing tube and come into contact with the inner wall of the return water tank, thereby forming a continuous water film on the tank wall. This increases the heat exchange area, resulting in a cooling effect far superior to that of local water columns or droplets.

[0016] When the temperature inside the return water tank is high, the present invention drives the rotating rod and fan blades to rotate via a stepper motor, thereby expelling the hot air from the return water tank to the outside. Furthermore, the top cooling fan, driven by a synchronous belt and linked to the bottom stirring mechanism, allows the circulating water inside the tank to break up the static stratification of the water, accelerate water convection heat transfer, and allow heat to spread quickly and evenly, significantly improving the overall heat dissipation and cooling effect, avoiding local heat accumulation. At the same time, there is no need to add a separate stirring motor, thereby reducing the number of drive components and lowering the equipment manufacturing cost.

[0017] When the transmission rod rotates, the invention also drives several movable blocks to move up and down at the same distance on the surface of the rod via a moving component. This causes the low-temperature water at the bottom to flow upward and the high-temperature water at the top to flow downward, accelerating the overall water temperature equalization. Furthermore, the circumferential water flow generated by the rotation and the vertical water flow generated by the up and down sliding form a complex turbulence, which makes the water body more fully disturbed. The heat exchange efficiency is far superior to that of simple rotation stirring. Combined with the top fan for heat dissipation, the cooling speed is greatly improved. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7 As shown, a built-in circulating cooling pipe network system for heavy-duty concrete structures includes a U-shaped cooling pipe 110 installed on a steel frame, and a water storage tank 120 and a return water tank 130 respectively fixed on the ground. A flow pipe 190 connects the water storage tank 120 and the return water tank 130. The system also includes a circulating water pump 140 installed on the ground. The suction end of the circulating water pump 140 is connected to the water storage tank 120, and the discharge end of the circulating water pump 140 is connected to one end of the U-shaped cooling pipe 110. The other end of the U-shaped cooling pipe 110 is connected to a drain pipe 150, and the other end of the drain pipe 150 passes through the return water tank 130 and extends into its interior. A swinging member 160 is provided at the other end of the drain pipe 150. The drain pipe 150 achieves the rotation and spraying of the swinging member 160 by the discharge force of the water flow. A heat dissipation part 170 is installed inside the U-shaped cooling pipe 110. The interior of the U-shaped cooling pipe 110 achieves the cooling of the tank body and the cooling of the circulating water by the rotation of the blades of the heat dissipation part 170.

[0022] The oscillating component 160 includes an internal oscillating tube 161 rotatably connected at one end to the other end of the drain pipe 150. A fixing plate 162 is fixedly connected inside one end of the oscillating tube 161. A fixing rod 163 is fixed to the top of the fixing plate 162. An impeller 164, which rotates due to water flow impact, is fixed to the top of the fixing rod 163. When water enters the drain pipe 150 for discharge, it impacts the impeller 164 and drives it to rotate. At the same time, the fixing rod 163 and the oscillating tube 161 rotate, so that the water sprayed out by the oscillating tube 161 can contact the inner wall of the return water tank 130, thereby increasing the heat dissipation area.

[0023] The heat dissipation unit 170 includes a stepper motor 171 fixed on the dustproof frame on the top of the return water tank 130. A rotating rod 172 is fixed to the output end of the stepper motor 171, and a fan blade 173 located above the drain pipe 150 is fixed to the top of the rotating rod 172. A stirring element 174 is provided at the bottom of the inner cavity of the return water tank 130, which can rotate and disturb the circulating water. A transmission element 175 is provided on the outside of the return water tank 130, which drives the stirring element 174 to rotate by the rotation of the fan blade 173. When the temperature in the return water tank 130 is high, the stepper motor 171 can be started, and the rotating rod 172 and the fan blade 173 can be driven to rotate, thereby dissipating the heat in the return water tank 130.

[0024] The agitator 174 includes a movable rod 1741 rotatably connected to the bottom of the inner cavity of the return water tank 130 and having a raised outer perimeter. A movable block 1742 adapted to the surface of the movable rod 1741 is slidably connected to the surface of the movable rod 1741. Several agitator rods 1743 are fixedly arranged around the surface of the movable block 1742. A connecting rod 1744 is fixedly arranged around the top of the movable block 1742, and the upper and lower movable blocks 1742 are fixed together by the connecting rod 1744. A movable ring 1745 is fixedly arranged at the top of the uppermost connecting rod 1744. When the fan blade 173 rotates, it can also drive the movable rod 1741 to rotate through the transmission component 175, and drive the movable block 1742 to rotate, so that the agitator rods 1743 can agitate and cool the circulating water.

[0025] The transmission component 175 includes two meshing bevel gear sets 1751 and 1757. The large bevel tooth of bevel gear set 1751 is fixed to the bottom of the fan blade 173, and a transmission rod 1752 is fixed to one side of the small bevel tooth. One bevel tooth of bevel gear set 1757 is fixed to the surface of the movable rod 1741. A reducer 1753 is fixed to the outside of the return water tank 130. The other end of the transmission rod 1752 is fixed to the shaft of the reducer 1753. A synchronous pulley 1754 is fixed to the other shaft of the reducer 1753. The synchronous pulley 1754 is connected to a synchronous pulley via a synchronous belt. Synchronous pulley 1755 has a transmission rod 1756 fixed to one side. The other end of synchronous pulley 1755 extends into the interior of the return water tank 130 and is fixed to another bevel gear of bevel gear 1757. When the fan blade 173 rotates, it also drives the transmission rod 1752 to rotate through bevel gear set 1751, and reduces the speed through reducer 1753, thereby reducing the rotation speed of synchronous pulley 1754. Then, synchronous belt drives synchronous pulley 1755 and transmission rod 1756 to rotate, thereby driving the movable rod 1741 to rotate through bevel gear 1757.

[0026] The surfaces of bevel gear 2 1757 and bevel gear set 1 1751 are fitted with waterproof protective shells.

[0027] The heat dissipation unit 170 also includes a movable component 176, which includes a half gear 1761 fixed to the surface of the transmission rod 1752. The surface of the half gear 1761 is meshed with a gear frame 1762 that moves up and down as it rotates. The bottom end of the gear frame 1762 is fixed with a folded connecting plate 1763. The other end of the connecting plate 1763 is rotatably connected to the movable ring 1745. When the transmission rod 1752 rotates, it also drives the half gear 1761 to rotate and drives the gear frame 1762 to move up and down reciprocally, thereby driving the connecting plate 1763 to move together. Since the movable ring 1745 is rotatably connected to the raised surface of the other end of the connecting plate 1763, it will not affect the rotation of the movable rod 1741. At the same time, it will also drive several movable blocks 1742 to move up and down to facilitate better disturbance.

[0028] A T-slot is provided on one side of the connecting plate 1763, and the inside of the T-slot is slidably connected to the fixing block 177 on the inner wall of the return water tank 130. Through the sliding connection of the fixing block 177 in the T-slot of the connecting plate 1763, the connecting plate 1763 can be auxiliaryly supported and its stability can be maintained when it moves.

[0029] The outer surface of the return water tank 130 is covered with several heat dissipation fins 180, which are arranged at equal intervals. By setting the heat dissipation fins 180, the heat of the circulating water can be discharged after the circulating water is sprayed onto the heat dissipation fins 180.

[0030] A filter screen 220 is installed at the connection between the flow pipe 190 and the return water tank 130. The filter screen 220 can intercept impurities in the return water tank 130 to prevent subsequent blockage.

[0031] The surface of the return water tank 130 is provided with several heat dissipation holes 200, which are located above the fan blade 173. A temperature detector 210 is installed on the inner wall of the return water tank 130. The heat dissipation holes 200 allow the heat in the return water tank 130 to be dissipated from the heat dissipation holes 200. At the same time, the temperature detector 210 can detect the heat in the return water tank 130.

[0032] Working principle: In use, the U-shaped cooling pipe 110 is first installed on the steel frame, and then cooling water is injected into the water storage tank 120. After the concrete is poured, the cooling water in the water storage tank 120 is drawn out by the operation of the circulating water pump 140 and transported to the U-shaped cooling pipe 110, so that the cooling water in the U-shaped cooling pipe 110 can cool the concrete. The cooled water after heat exchange will enter the return water tank 130 through the drain pipe 150. At this time, the circulating water will be sprayed onto the inner wall of the return water tank 130 by the swing component 160. If the temperature detected by the temperature detector 210 is high, the stepper motor 171 will be turned on, driving the rotating rod 172 and the fan blade 173 to rotate, thereby cooling the water in the return water tank 130. Heat is dissipated, and as the fan blade 173 rotates, the rotation of the bevel gear set 1751 and the transmission rod 1752 drives the movable rod 1741 to rotate via the synchronous belt. The movable part 176 also drives the uppermost movable block 1742 to move, thereby driving the stirring rod 1743 to move together. The stirring rod 1743 rotates and moves up and down at the same time, which causes the low-temperature water at the bottom to flow upward and the high-temperature water at the top to flow downward, thus accelerating the overall water temperature equalization. In addition, the circumferential water flow generated by the rotation and the vertical water flow generated by the up and down sliding form a compound turbulence, which makes the water body more fully disturbed. The heat exchange efficiency is far superior to that of simple rotation stirring. Combined with the cooling of the top fan, the cooling speed is greatly improved.
