Description

Technical Field

[0001] This invention relates to the field of dynamic intelligent temperature control technology for concrete, and particularly to dynamic intelligent temperature control equipment and its usage method for large-volume concrete. Background Technology

[0002] Cracking in large-volume concrete has various causes, with temperature cracking being a common one. The combined effect of temperature changes caused by the heat of hydration released during cement hydration and concrete shrinkage leads to accumulated temperature stress within the concrete exceeding the material's tensile strength, resulting in harmful cracks in the concrete structure. Once formed, these cracks severely impact the integrity, impermeability, and durability of the concrete structure. Controlling crack formation is therefore a pressing need for quality control in large-volume concrete. Conducting temperature control measures for large-volume concrete provides technical support for crack control and is a crucial means of ensuring the durability and operational safety of concrete structures, making it of paramount importance.

[0003] Currently, temperature control for large-volume concrete in China mostly relies on automatic timed temperature monitors to read and record temperature data. This data is then manually processed and analyzed in conjunction with temperature control indicators to guide on-site construction. This manual data reading, analysis, and reporting increases the workload of on-site temperature control personnel and cannot achieve real-time accuracy. Manual judgment and adjustment of cooling water are time-consuming, have a certain lag, and are inefficient, affecting the cooling effect. Furthermore, the temperature control system has low intelligence, requiring dedicated personnel for 24-hour monitoring, which is insufficient to meet the high-quality and rapid construction requirements of modern large-volume concrete projects. The use of multiple devices in the application area also increases the risk of equipment damage and inaccurate information collection due to poor wireless signal transmission. Therefore, this application provides a dynamic intelligent temperature control device and its usage method for large-volume concrete to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dynamic intelligent temperature control device for large-volume concrete and a method for using it to solve the problems of inaccurate information collection caused by the lack of centralized equipment, difficulty in transporting multiple devices, lack of coordination in synchronous use, and poor signal transmission at the construction site.

A moving component is installed on the lower part of the equipment base plate. A water tank component is snapped onto the upper surface of the equipment base plate.

[0007] Optionally, the wireless device box has multiple device storage slots inside. A wireless temperature sensor is clipped into the device storage slot on one side of the wireless device box, and a wireless temperature and humidity sensor is clipped into the device storage slot on the other side of the wireless device box. A battery is installed inside the wireless device box.

[0008] Optionally, a data relay station is attached to one side of the control transceiver box, a wireless transmitter and receiver are installed on the upper surface of the control transceiver box, and a maintenance controller and a cooling water controller are installed sequentially from bottom to top on the other side of the control transceiver box.

[0009] Optionally, the moving assembly includes a docking base plate, a rotating shaft, a wheel seat, a wheel axle, a moving wheel, pneumatic feet, a shock-absorbing spring seat, and a shock-absorbing spring rod. The docking base plate is rotatably connected to the wheel seat via the rotating shaft. The wheel seat is rotatably connected to the wheel axle. The surface of the wheel axle is fitted with a shock-absorbing spring seat. The upper surface of the shock-absorbing spring seat is provided with a shock-absorbing spring rod. Moving wheels are installed at both ends of the wheel axle.

[0010] Optionally, the water tank assembly includes a water tank, a heating plate, heat exchange scales, an air guide plate, and a water tank cover. The heating plate is installed on one side of the inside of the water tank, the heat exchange scales are fixedly connected to one side of the water tank, the air guide plate is slidably connected to the upper part of the heat exchange scales, and the water tank cover is snapped onto the upper part of the water tank.

[0011] Optionally, the damping spring seat is located on both sides of the wheel axle, and the upper surface of the damping spring seat is provided with two damping spring rods, the upper surface of the damping spring rods being adapted to the lower surface of the mating base plate.

[0012] Optionally, an ultrasonic fog cannon is mounted on the upper surface of the equipment base plate via a bracket. A locating groove is provided on the upper surface of the equipment base plate, and a hot air cannon is engaged inside the locating groove. The equipment base plate has four locating grooves, which can accommodate two hot air cannons.

[0013] Optionally, a column head docking frame is installed on one side of the equipment base plate, and a vehicle hook can be installed at the front end of the column head docking frame.

[0014] Optionally, a lower plate is rotatably connected to one side of the equipment base plate via a ratchet seat, and one end of the lower plate is sloped at a 45-degree angle.

[0015] The method of using a dynamic intelligent temperature control device for large-volume concrete includes the following steps:

[0016] Step 1: In the preliminary preparation, the equipment is transported to the maintenance site by connecting the vehicle hook of the column head docking frame to the engineering vehicle. After the device is in place, the pneumatic support feet are activated to position the equipment, and the on-site water source is connected to the wireless flow meter. The through screw motor is activated to lower the control transceiver box to a height that is convenient for personnel to operate, and the ratchet seat is released to make the lower plate reverse downward and contact the ground.

[0017] Step 2: Personnel remove the wireless temperature sensor and the wireless temperature and humidity sensor, connect them wirelessly to the wireless transmitter and receiver in the equipment, and place them in the maintenance area where they need to be monitored.

[0018] Step 3: Based on the condition of the maintenance area, turn on the maintenance controller and cooling water controller, and control the hot air cannon and ultrasonic fog cannon. Set fixed thresholds, record them through the data transfer station, and automatically adjust the hot air cannon and ultrasonic fog cannon.

[0019] Step 4: Connect the inner and outer wireless flow regulating valves to the buried cooling water pipes. When the concrete covers the cooling water pipes, the outer and inner wireless flow regulating valves start to flow water. The wireless flow meter starts counting the flow and simultaneously sends the information to the data relay station 20. The cooling water basically operates at full flow. During the concrete cooling stage, the cooling water flow rate changes accordingly according to the cooling rate until it automatically shuts off. The cooling water inlet temperature is 28.6~49.3℃, the outlet temperature is 26.3~50.6℃, and the cooling water inlet and outlet temperature difference is 0.2~4.9℃, which meets the temperature control standards of ≤10℃ for cooling water inlet and outlet temperature difference and ≤25℃ for the temperature difference between cooling water and the inside of concrete. Combined with Step 3, the internal and external humidity and temperature are regulated.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting an outer ring wireless flow regulating valve and an inner ring wireless flow regulating valve, which are connected to the buried cooling water pipe, the outer ring wireless flow regulating valve and the inner ring wireless flow regulating valve start to flow water when the concrete covers the cooling water pipe. The wireless flow meter starts to count the flow and sends the information to the data relay station. The cooling water basically operates at full flow. During the concrete cooling stage, the cooling water flow rate changes accordingly according to the cooling rate until it automatically shuts off. The cooling water inlet temperature is 28.6~49.3℃, the outlet temperature is 26.3~50.6℃, and the cooling water inlet and outlet temperature difference is 0.2~4.9℃, which meets the temperature control standards of cooling water inlet and outlet temperature difference ≤10℃ and cooling water temperature difference ≤25℃.

[0022] Wireless temperature and humidity sensors are placed at the locations where measurements are needed to collect data on-site. When the equipment is not in use, the wireless temperature and humidity sensors can be pre-charged by the battery installed inside the wireless equipment box to avoid data collection failure due to insufficient power when the equipment is removed.

[0023] The hot air cannon can blow hot air outward from the equipment to heat the air, forming warm air of a certain temperature that is introduced into the closed curing area to increase the temperature of the curing area. At the same time, the air guide plate can be pulled out to divert part of the hot air blown out by the hot air cannon to the heat exchange scale to preheat the water in the water tank. Then, the water is sprayed out as a fine mist through an ultrasonic mist cannon, avoiding the water mist cooling the hot air blown out by the hot air cannon. The hot air cannon can also be removed from the equipment base plate and placed in other curing locations, achieving the effect of multi-area and multi-angle curing. After the moving component moves the equipment to the required position, the pneumatic support feet can be activated to position the equipment and prevent the equipment from shifting during internal mechanical operation. Shock-absorbing spring rods are installed on both sides of the wheel axle to ensure that the equipment can move relatively horizontally during movement and prevent the equipment from shifting.

[0024] In summary, this invention has the advantages of centralized equipment transportation, simultaneous and separate use, and signal relay and acquisition. Attached Figure Description

[0042] like Figure 1 and Figure 2As shown, the embodiments of the present invention provide a dynamic intelligent temperature control device for large-volume concrete and a method of use, including a device base plate 1. A water distribution plate 2 is installed on one side of the device base plate 1. The water distribution plate 2 has an outer ring pump connection hole and an inner ring pump connection hole sequentially opened from top to bottom. An outer ring wireless flow regulating valve 3 is installed inside the outer ring pump connection hole, and an inner ring wireless flow regulating valve 4 is installed inside the inner ring pump connection hole. An upper water inlet pipe 5 is provided at one end of the outer ring wireless flow regulating valve 3, and a lower water inlet pipe 6 is provided at one end of the inner ring wireless flow regulating valve 4. A water distribution pipe 7 is sleeved at one end of the upper water inlet pipe 5, and a wireless flow meter 8 is installed at one end of the water distribution pipe 7.

[0043] By connecting the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4 to the buried cooling water pipe, water begins to flow through the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4 when the concrete covers the cooling water pipe. The wireless flow meter 8 starts counting the flow and sends the information to the data relay station 20. The cooling water basically operates at full flow. During the concrete cooling stage, the cooling water flow rate changes accordingly according to the cooling rate until it automatically shuts off. The cooling water inlet temperature is 28.6~49.3℃, the outlet temperature is 26.3~50.6℃, and the cooling water inlet and outlet temperature difference is 0.2~4.9℃, which meets the temperature control standards of cooling water inlet and outlet temperature difference ≤10℃ and cooling water temperature difference ≤25℃.

[0044] like Figure 3 , Figure 4 and Figure 8 As shown, in this embodiment, the wireless device box 9 has multiple device storage slots inside. A wireless temperature sensor 17 is snapped into a device storage slot on one side of the wireless device box 9, and a wireless temperature and humidity sensor 18 is snapped into a device storage slot on the other side of the wireless device box 9. A battery 19 is installed inside the wireless device box 9. A through-screw motor 10 is fixedly connected to one side of the upper surface of the device base plate 1. A lifting screw 11 passes through the inside of the through-screw motor 10. An upper bracket 12 is rotatably connected to the top of the lifting screw 11. A control transceiver box 13 is provided on the lower surface of the upper bracket 12. The transceiver box 13 has a lower support 14 on one side of its lower part. A data relay station 20 is snapped into one side of the inside of the transceiver box 13. A wireless transmitter and receiver 21 is installed on the upper surface of the transceiver box 13. A maintenance controller 22 and a cooling water controller 23 are installed sequentially from bottom to top on the other side of the inside of the transceiver box 13. A column head docking frame 26 is installed on one side of the equipment base plate 1. A vehicle hook can be installed at the front end of the column head docking frame 26. A lower plate 28 is rotatably connected to one side of the equipment base plate 1 through a ratchet seat 27. One end of the lower plate 28 is sloped at a 45-degree angle.

[0045] By placing the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18 at the locations where measurements are required, on-site data collection can be performed. When the equipment is not in use, the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18 can be pre-charged by the battery 19 installed inside the wireless equipment box 9, so as to avoid data collection failure due to lack of power when the equipment is removed.

[0046] The rotation of the through-screw motor 10 drives the lifting screw 11 to rise and fall, causing the control transceiver box 13 to rise and fall together. When the equipment is moved, the control transceiver box 13 can be raised to the upper part of the base plate 1 to avoid damage to the wireless transmitter / receiver 21, maintenance controller 22 and cooling water controller 23 during movement. After the wireless temperature sensor 17 and wireless temperature and humidity sensor 18 are installed on site, the cooling water controller 23 controls the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4 to achieve an automated adjustment effect. Moreover, through the wireless transmitter / receiver 21 and the data relay station, comprehensive control of various temperature parameters can be achieved without human intervention. After the equipment reaches the predetermined position, the through-screw motor 10 lowers the control transceiver box 13 to facilitate subsequent operation by personnel. At the same time, the lower plate 28 can be folded down to facilitate the unloading of the movable equipment on the upper part of the equipment base plate 1 and to facilitate personnel to access the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18.

[0047] like Figures 5 to 7 As shown, in this embodiment, the lower part of the equipment base plate 1 is provided with a moving assembly 15. The moving assembly 15 includes a docking base plate 1501, a rotating shaft 1502, a wheel seat 1503, a wheel axle 1504, a moving wheel 1505, a pneumatic support foot 1506, a shock-absorbing spring seat 1507, and a shock-absorbing spring rod 1508. The docking base plate 1501 is rotatably connected to the wheel seat 1503 via the rotating shaft 1502. The wheel axle 1504 is rotatably connected inside the wheel seat 1503. The shock-absorbing spring seat 1507 is sleeved on the surface of the wheel axle 1504. The shock-absorbing spring rod 1508 is provided on the upper surface of the shock-absorbing spring seat 1507. The moving wheels 1505 are installed at both ends of the wheel axle 1504. The upper surface of the equipment base plate 1 is secured with... A water tank assembly 16 is provided, which includes a water tank 1601, a heating plate 1602, a heat exchange scale 1603, an air guide plate 1604, and a water tank cover 1605. The heating plate 1602 is installed on one side of the inside of the water tank 1601, and the heat exchange scale 1603 is fixedly connected to one side of the water tank 1601. The air guide plate 1604 is slidably connected to the upper part of the heat exchange scale 1603, and the water tank cover 1605 is snapped onto the upper part of the water tank 1601. An ultrasonic fog cannon 24 is installed on the upper surface of the equipment base plate 1 through a bracket. A retaining groove is opened on the upper surface of the equipment base plate 1, and a hot air cannon 25 is snapped into the inside of the retaining groove. The equipment base plate 1 has four retaining grooves, which can accommodate two hot air cannons 25.

[0048] After placing the device in the required location, the hot air cannon 25 can spray hot air outward from the equipment to heat the air, forming warm air of a certain temperature that is introduced into the closed curing area to increase the temperature of the curing area. At the same time, the air guide plate 1604 can be pulled out to guide part of the hot air blown out by the hot air cannon 25 to the heat exchange scale 1603 to preheat the water in the water tank 1601. Then, the water is sprayed out as a water mist with a very small particle size through the ultrasonic mist cannon 24, which avoids the water mist cooling the hot air blown out by the hot air cannon 25. The hot air cannon 25 can also be removed from the equipment base plate 1 and placed in other curing locations, achieving the effect of multi-area and multi-angle curing.

[0049] After the device is moved to the required position by the moving component 15, the pneumatic support feet 1506 can be activated to position the device, preventing the device from shifting during internal mechanical operation. Furthermore, shock-absorbing spring rods 1508 are installed on both sides of the axle 1504, allowing the device to move relatively horizontally during movement and preventing the device from shifting during movement.

[0050] The method of using a dynamic intelligent temperature control device for large-volume concrete includes the following steps:

[0051] Step 1: In the preliminary preparation, the equipment is transported to the maintenance site by connecting the vehicle hook of the column head docking frame 26 to the engineering vehicle. After the device is in place, the pneumatic support foot 1506 is activated to position the equipment, and the on-site water source is connected to the wireless flow meter 8. The through screw motor 10 is activated to lower the control transceiver box 13 to a height that is convenient for personnel to operate, and the ratchet seat 27 is released to make the lower plate 28 reverse downward and contact the ground.

[0052] Step 2: Personnel take out the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18, connect them wirelessly to the wireless transmitter and receiver 21 in the equipment, and place the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18 at the locations in the maintenance area that need to be tested.

[0053] Step 3: Based on the condition of the maintenance area, turn on the maintenance controller 22 and the cooling water controller 23, and control the hot air cannon 25 and the ultrasonic fog cannon 24. Set a fixed threshold, record it through the data transfer station 20, and automatically adjust the hot air cannon 25 and the ultrasonic fog cannon 24.

[0054] Step 4: Connect the outer and inner wireless flow regulating valves 3 and 4 to the buried cooling water pipe. When the concrete covers the cooling water pipe, the outer and inner wireless flow regulating valves 3 and 4 begin to flow water. The wireless flow meter 8 starts counting the flow and simultaneously sends the information to the data relay station 20. The cooling water basically operates at full flow. During the concrete cooling stage, the cooling water flow rate changes accordingly according to the cooling rate until it automatically shuts off. The cooling water inlet temperature is 28.6~49.3℃, the outlet temperature is 26.3~50.6℃, and the cooling water inlet and outlet temperature difference is 0.2~4.9℃, which meets the temperature control standards of ≤10℃ for the cooling water inlet and outlet temperature difference and ≤25℃ for the temperature difference between the cooling water and the inside of the concrete. Combined with Step 3, the internal and external humidity and temperature are regulated.

[0055] The working principle provided by this invention is as follows: By connecting the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4 to the buried cooling water pipe, water begins to flow through the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4 when the concrete covers the cooling water pipe. The wireless flow meter 8 starts counting the flow and simultaneously sends the information to the data relay station 20. The cooling water basically operates at full flow. During the concrete cooling stage, the cooling water flow rate changes accordingly according to the cooling rate until it automatically shuts off. The cooling water inlet temperature is 28.6~49.3℃, the outlet temperature is 26.3~50.6℃, and the temperature difference between the cooling water inlet and outlet is 0.2~4℃.The temperature is 9℃, which meets the temperature control standards of ≤10℃ for the temperature difference between the inlet and outlet of the cooling water and ≤25℃ for the temperature difference between the cooling water and the internal temperature of the concrete. Wireless temperature sensor 17 and wireless temperature and humidity sensor 18 are placed at the locations where measurements are required for on-site data acquisition. When the equipment is not in use, the wireless temperature sensor 17 and wireless temperature and humidity sensor 18 can be pre-charged using the battery 19 installed inside the wireless equipment box 9 to prevent data acquisition failure due to insufficient power when the equipment is removed. The rotation of the through-screw motor 10 drives the lifting screw 11 to rise and fall, causing the control transceiver box 13 to rise and fall together. When the equipment is moved, the control transceiver box 13 can be raised to the top of the base plate 1 to avoid damage to the wireless transmitter / receiver 21, maintenance controller 22, and cooling water controller 23 during movement. After the wireless temperature sensor 17 and wireless temperature and humidity sensor 18 are installed on site, the cooling water controller 23 controls the outer ring wireless flow regulating valve 3 and the inner ring wireless flow regulating valve 4, achieving an automated adjustment effect. Furthermore, through the wireless transmitter / receiver 21 and data relay station, comprehensive control of various temperature parameters is achieved without human intervention. After the equipment reaches the predetermined position, the through-screw electric motor... Machine 10 lowers the transceiver box 13 for easier subsequent operation. Simultaneously, the lower platform 28 can be folded down, facilitating the unloading of movable equipment on the upper part of the equipment base plate 1 and allowing personnel to easily access the wireless temperature sensor 17 and the wireless temperature and humidity sensor 18. After placing the device in the desired location, the hot air cannon 25 can spray hot air from the equipment to heat the air, creating warm air at a certain temperature that is introduced into the enclosed curing area to raise the temperature of the curing area. Simultaneously, the air guide plate 1604 can be pulled out to divert a portion of the hot air blown by the hot air cannon 25 to the heat exchange scale 1603 to preheat the water in the water tank 1601. The ultrasonic mist cannon 24 sprays water into a fine mist, preventing the water mist from cooling the hot air blown by the hot air cannon 25. The hot air cannon 25 can also be removed from the equipment base plate 1 and placed in other locations requiring maintenance, achieving multi-area and multi-angle maintenance. After moving the equipment to the required position using the moving component 15, the pneumatic support feet 1506 can be activated to position the equipment, preventing it from shifting during internal mechanical operation. Furthermore, shock-absorbing spring rods 1508 are installed on both sides of the axle 1504, allowing the equipment to move relatively horizontally and preventing shifting during movement.
