Description

Technical Field

[0001] The present invention relates to the technical field of concrete, and in particular to an intelligent cooling water pipe device and method for temperature control of large-volume concrete. Background Art

[0002] When pouring large-volume concrete, a large amount of hydration heat will be generated, and the internal temperature can reach above 85°C. Due to the rapid heat exchange on the concrete surface, a large temperature difference is easily formed inside and outside the concrete, which causes temperature deformation in different areas of the concrete. Due to the uncoordinated deformation of each part, large-volume concrete will have a large temperature stress. For some large-volume concrete, the temperature stress generated by the hydration heat can reach the same stress level as the dead load stress. Therefore, in the early stage of pouring concrete, a large amount of hydration heat will cause serious damage to the concrete structure. The higher the concrete strength, the more intense the hydration effect. Therefore, for large-volume concrete structures, it is very necessary to use cooling water pipes to cool down the large-volume concrete.

[0003] When the buried water pipe in the large volume concrete is long, the water inlet is low and the outlet temperature will increase significantly. The existing cooling water pipe cannot monitor the water temperature change in the water pipe, and thus cannot adjust the flow of cooling water to achieve the ideal cooling effect. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent cooling water pipe device for temperature control of large-volume concrete and a control method thereof, so as to achieve continuous cooling of the concrete and protect the concrete structure.

[0005] To solve the above technical problems, the present invention provides a technical solution: an intelligent cooling water pipe device for temperature control of large-volume concrete, comprising a cooling water pipe, a control module, and an intelligent conversion head; the cooling water pipe is laid in the concrete, and its two ends are respectively connected to the water inlet and the water outlet through the intelligent conversion head; the control module controls the water flow rate in the cooling water pipe by controlling the intelligent conversion head according to the temperature data and water flow rate data collected by the intelligent conversion head.

[0006] According to the above scheme, a temperature sensor for collecting temperature data, a water flow rate sensor for collecting water flow rate data, and an electronic valve for controlling the water flow rate are arranged in the intelligent conversion head.

[0007] According to the above scheme, the cooling water pipe includes a main water pipe and a plurality of secondary water pipes. The secondary water pipes surround the main water pipe, and the main water pipe and the secondary water pipes are interconnected at the water outlet and the water inlet.

[0008] According to the above scheme, the number of secondary water pipes is 4 or other number.

[0009] According to the above scheme, the diameter of the secondary water pipe is 1 / 3 to 1 / 6 of the diameter of the main water pipe.

[0010] According to the above scheme, the cooling water pipe is a steel pipe or a corrugated steel pipe.

[0011] According to the above solution, the secondary water pipe is connected to the main water pipe by welding.

[0012] According to the above scheme, the cooling water pipe is laid in the concrete in an S shape.

[0013] The present invention also provides an intelligent cooling water pipe control method for mass concrete temperature control, comprising:

[0014] S1. Obtain the temperature data of the water inlet and outlet;

[0015] S2. Control the water flow rate of the cooling water pipe according to the difference between the temperature data of the water outlet and the temperature data of the water inlet.

[0016] According to the above scheme, the method includes: S3, obtaining water flow rate data of the water inlet and the water outlet; judging whether the cooling water pipe is leaking according to the water flow rate data of the water inlet and the water outlet.

[0017] The beneficial effect of the present invention is that the present invention can monitor the inlet and outlet temperature data and water flow rate data of the cooling water pipe through the intelligent conversion head set up, and then can judge the cooling effect and whether there is water leakage through the control module, and control the intelligent conversion head according to the judgment result to adjust the water flow rate to ensure sufficient cooling of the concrete.

[0018] Furthermore, the present invention increases the contact area between the cooling water pipe and the concrete by configuring the cooling water pipe to be a main water pipe and a plurality of secondary water pipes, thereby increasing the heat exchange efficiency between the cooling water and the concrete and thus improving the cooling effect.

[0024] Embodiment 1:

[0025] See also Figure 1 Based on the problems existing in the prior art in the background technology, the present embodiment provides an intelligent cooling water pipe device for temperature control of large-volume concrete, including a cooling water pipe 1, a control module 2, and an intelligent conversion head 3; the cooling water pipe 1 is arranged in the concrete 6, and its two ends are respectively connected to the water inlet 4 and the water outlet 5 through the intelligent conversion head 3; the control module 2 controls the water flow rate in the cooling water pipe 1 by controlling the intelligent conversion head 3 according to the temperature data and water flow rate data collected by the intelligent conversion head 3.

[0026] Furthermore, the cooling water pipe 1 is arranged in the concrete 6 in an S shape; in other embodiments of the present invention, the cooling water pipe 11 may be arranged in the concrete 6 in a zigzag shape.

[0027] Embodiment 2:

[0028] Existing cooling water pipes for large-volume concrete all use single-hole pipes. When buried inside the concrete, the contact area between the single-hole pipe and the concrete is limited, so it cannot effectively reduce the internal temperature of the large-volume concrete. If the temperature cannot be reduced quickly, it is easy to cause concrete quality problems.

[0029] See also Figure 2 Based on the above problems, this embodiment provides a cooling water pipe 1 on the basis of the first embodiment. The cooling water pipe 1 includes a main water pipe 11 and a plurality of secondary water pipes. The secondary water pipes surround the main water pipe 11. The main water pipe 11 and the secondary water pipes are interconnected at the water outlet and the water inlet.

[0030] Furthermore, the number of secondary water pipes is 4 (other numbers may be set in other embodiments of the present invention), namely the first water pipe 7, the second water pipe 8, the third water pipe 9, and the fourth water pipe 10, and their diameters are 1 / 3 to 1 / 6 of the diameter of the main water pipe 11.

[0031] Furthermore, the cooling water pipe 1 is a steel pipe or a corrugated steel pipe, and the secondary water pipe is connected to the main water pipe 11 by welding.

[0032] See also Figure 3The intelligent conversion head 3 of this embodiment is provided with a temperature sensor 12 for collecting temperature data, a water flow rate sensor 13 for collecting water flow rate data, and an electronic valve 14 for controlling the water flow rate.

[0033] Embodiment three:

[0034] Based on the intelligent cooling water pipe device for mass concrete temperature control provided in the first embodiment, this embodiment provides an intelligent cooling water pipe control method for mass concrete temperature control, including:

[0035] S1, obtaining the temperature data of the water inlet 4 and the water outlet 5;

[0036] S2. Control the water flow rate of the cooling water pipe 1 according to the difference between the temperature data of the water outlet 5 and the temperature data of the water inlet 4.

[0037] This embodiment determines the cooling effect of the cooling water pipe 1 by monitoring the temperatures of the water inlet and outlet, wherein the control logic of the water flow rate of the cooling water pipe 1 may be: when the difference is greater than a certain value, the water flow rate is increased (by controlling the electronic valve 14) to enhance the cooling effect; when the difference is less than a certain value, the water flow rate is reduced or the water flow is stopped.

[0038] Embodiment 4:

[0039] When a cooling water pipe installed in a large volume of concrete cracks and causes water leakage, it is impossible to observe whether there is leakage from the concrete surface. At this time, the cooling effect is poor and water resources are wasted.

[0040] Based on the above problems, this embodiment provides an intelligent cooling water pipe control method for mass concrete temperature control based on the method described in Embodiment 3, including:

[0041] S1, obtaining the temperature data of the water inlet 4 and the water outlet 5;

[0042] S2, controlling the water flow rate of the cooling water pipe 1 according to the difference between the temperature data of the water outlet 5 and the temperature data of the water inlet 4;

[0044] Through the leakage judgment results, construction workers can discover leakage in time and conduct inspections and maintenance to avoid losses caused by poor concrete cooling effects.
