A third solenoid valve 14 is installed on the surface of the 0, a fourth solenoid valve 15 is installed on the surface of the first return water pipe 5, and a first solenoid valve 12 is installed on the surface of the second return water pipe 6. The heat dissipation device has a first return water pipe 5 and a second return water pipe 6 on the cooling water pipe 4. The cooling water source inside the cooling water tank 7 can enter the cooling water pipe 4 through the second return water pipe 6 and then return to the cooling water tank 7 through the first return water pipe 5, or it can enter the cooling water pipe 4 through the second return water pipe 6 and then return to the cooling water tank 7 through the second return water pipe 6. This reduces the degree of uneven cooling of the concrete body 3 by the cooling water pipe 4, improves the uniformity of cooling of the concrete body 3, and ensures the quality of concrete production.
[0023] Furthermore, a support block 16 is fixedly connected to the surface of the concrete formwork 2, a motor 17 is fixedly connected to the surface of the support block 16, a lead screw 18 is fixedly connected to the output shaft of the motor 17, a nut block 19 is threadedly connected to the surface of the lead screw 18, a guide rod 20 is fixedly connected to the surface of the support block 16, a slider 21 is slidably connected to the surface of the guide rod 20, a steel pipe 22 is fixedly connected to the surface of the slider 21, a spray head 23 is fixedly connected to the surface of the steel pipe 22, a second water pipe 24 is fixedly installed at the output end of the water inlet pipe 8, and a connecting hose 25 is fixedly connected to the output end of the second water pipe 24. The steel pipe 22 can move to drive the spray head 23 to move, thereby making the spray head 23 spray evenly on the surface of the concrete body 3, ensuring the uniformity of the spray from the spray head 23, and thus making the concrete body 3 cool down evenly.
[0024] Furthermore, the cooling water pipe 4 is in a continuously curved shape and the overall shape of the cooling water pipe 4 is square, so that the cooling of the cooling water pipe 4 can radiate to the entire concrete body 3. The first return water pipe 5 and the second return water pipe 6 are both fixedly connected to the bottom of the inlet pipe 8 to receive the used cooling water inside the cooling water pipe 4.
[0025] Furthermore, the output pipe 10 is provided with two output ends, and the two output ends of the output pipe 10 are respectively fixedly connected to the first return water pipe 5 and the second return water pipe 6. The third solenoid valve 14 and the second solenoid valve 13 are respectively provided on one side of the two output ends of the output pipe 10. The second solenoid valve 13 and the third solenoid valve 14 respectively control the water outlet switches at both ends of the output pipe 10.
[0026] Furthermore, the cooling water tank 7 is replenished with water through the inlet pipe 8, and the first water pump 11 outputs the cooling water source inside the cooling water tank 7 through the outlet pipe 10, and then outputs it to the cooling water pipe 4 through the first return pipe 5 and the second return pipe 6. The cooling water source cools the concrete body 3 through the cooling water pipe 4.
[0027] Furthermore, the end of the steel pipe 22 away from the slider 21 is fixedly connected to the nut block 19. Multiple sets of spray heads 23 are provided, and the spray heads 23 are arranged linearly and evenly on the steel pipe 22. The end of the connecting hose 25 away from the second water pipe 24 is connected to the steel pipe 22 through the nut block 19. The second water pipe 24 outputs water to the inside of the steel pipe 22 through the connecting hose 25. The steel pipe 22 then atomizes the water through the spray heads 23 and sprays it onto the surface of the concrete body 3 to cool the solidified concrete body 3.
[0028] Furthermore, the support block 16 is provided with four sets. The lead screw 18 rotates on the support block 16 through the output shaft of the motor 17. The nut block 19 slides on the concrete template 2 through the rotation of the lead screw 18. The nut block 19 drives the steel pipe 22 and the spray head 23 to slide synchronously on the concrete template 2. The slider 21 guides the movement direction of the steel pipe 22 by sliding on the guide rod 20. The steel pipe 22 changes the cooling position of the spray head 23 on the surface of the concrete body 3 by sliding.
[0029] Working principle: When the second solenoid valve 13 is open, the fourth solenoid valve 15 is also open. At this time, the first solenoid valve 12 and the third solenoid valve 14 are closed. The first water pump 11 outputs the cooling water source inside the cooling water tank 7 through the output pipe 10 to the cooling water pipe 4 through the second return water pipe 6, and then returns it to the cooling water tank 7 through the first return water pipe 5. When the third solenoid valve 14 is open, the first solenoid valve 12 is also open. At this time, the second solenoid valve 13 and the fourth solenoid valve 15 are closed. The first water pump 11 outputs the cooling water source inside the cooling water tank 7 through the output pipe 10 to the cooling water pipe 4 through the first return water pipe 5, and then returns it to the cooling water tank 7 through the second return water pipe 6. By continuously changing the cooling water, the first return water pipe 5 and the second return water pipe 6 enter the cooling water pipe 4, thereby reducing the uneven cooling of the concrete body 3 by the cooling water pipe 4, improving the uniformity of cooling of the concrete body 3, and ensuring the quality of concrete production.
[0030] The second water pipe 24 inputs cooling water from the cooling water tank 7 into the steel pipe 22 via the connecting hose 25. The steel pipe 22 then atomizes the cooling water through the spray head 23 and outputs it onto the surface of the concrete body 3. The motor 17 drives the lead screw 18 to rotate through the output shaft. The lead screw 18 rotates and drives the nut block 19 to slide on the concrete template 2. The slider 21 guides the movement direction of the steel pipe 22 by sliding on the guide rod 20. During the sliding process, the steel pipe 22 changes the cooling position of the spray head 23 on the surface of the concrete body 3, thereby ensuring the uniformity of cooling of the solidified concrete body 3.
