Description

Technical Field

[0001] The utility model belongs to the technical field of building equipment and provides a large-volume concrete remote temperature control system. Background Art

[0002] During the construction of large-volume concrete structures, the thick structure and large amount of concrete make it impossible for the hydration heat inside the concrete to be dissipated in time, so that it accumulates higher and higher, increasing the temperature difference between the inside and outside, and easily causing temperature deformation of the structure. Because the plane size is too large, the temperature force generated by the constraint effect is also greater. If the temperature control measures are not taken properly, when the temperature stress exceeds the tensile limit that the concrete can withstand, cracks are likely to occur. Therefore, during the construction of concrete, the temperature of the concrete needs to be monitored and controlled.

If no warming and insulation measures are taken on the outside of the large-volume concrete, the large-volume concrete may still crack on the surface due to the large temperature difference between the outer surface and the inside.

The water inlet of the cooling water pump (6) is connected to a cooling water tank (7). The water outlet of the cooling water pipe (2) extends out of the concrete (1). The concrete (1) is connected to a cooling water tank (7), and the cooling water pump (6) is wirelessly connected to a remote control center (5) via a remote controller (8); the outer surface of the concrete (1) is covered with a heat insulation pad (9), and an outer surface temperature and humidity sensor (10), a heat preservation device (11) and a moisture retention device (12) are arranged between the heat insulation pad (9) and the outer surface of the concrete (1); the outer surface temperature and humidity sensor (10) is connected to the remote control center (5) via a temperature measuring instrument host (4), and the heat preservation device (11) and the moisture retention device (12) are wirelessly connected to the remote control center (5) via a remote controller (8).

[0022] The remote controller (8) is provided with a PLC or a single-chip microcomputer, and is controlled by the PLC or the single-chip microcomputer; wherein the PLC or the single-chip microcomputer is connected to a wireless communication module (not shown), and is wirelessly connected to the remote control center (5) via the wireless communication module.

[0023] The thermometer host (4) is provided with a single-chip microcomputer, which is connected to an internal temperature measuring device (3) through the single-chip microcomputer for temperature detection; the single-chip microcomputer is connected to an external temperature and humidity sensor (10) for temperature and humidity detection; wherein the single-chip microcomputer is connected to a wireless communication module (not shown), and the wireless communication module is wirelessly connected to a remote control center (5).

[0024] The cooling water tank (7) is provided with a cooling fan, or its outer wall is provided with heat dissipation equipment such as heat sinks.

[0025] The cooling water pipe (2) is evenly distributed in the concrete (1) in an S-shaped or spiral shape. The internal temperature measuring device (3) is used to detect the internal temperature of the concrete (1) and send the temperature to the remote control center (5) through the temperature measuring instrument host (4). When the temperature difference between the inside and outside of the concrete (1) is too large, the remote control center (5) starts the cooling water pump (6) through the remote controller (8). The cooling water pump (6) draws cooling water from the cooling water tank (7) and pumps the cooling water into the cooling water pipe (2) from the water inlet. The cooling water flows back into the cooling water tank (7) from the water outlet of the cooling water pipe (2), thereby cooling the inside of the large volume of concrete (1).

[0026] When the external ambient temperature is too low, for example, below 10 degrees, the provision of a heat insulating pad (9) is helpful in maintaining the temperature of the outer surface of the concrete (1), reducing the temperature difference between the outer surface and the interior of the concrete (1), and preventing the outer surface of the concrete (1) from cracking.

When the humidity of the outer surface of the concrete (1) is too low, the remote control center (5) activates the moisturizing device (12) through the remote controller (8) to keep the outer surface of the concrete (1) moisturized, thereby preventing cracking.

The heating water pump (13) draws hot water to flow into the water inlet of the heating water pipe (111), and the water in the heating water pipe (111) flows back to the heating water tank (14) from the water outlet of the heating water pipe (111). The outer surface of the concrete (1) is heated by the hot water, and the outer surface of the concrete (1) is kept warm, thereby reducing the temperature difference between the inside and the outside. When the temperature requirement is reached, the heating water pump (13) is turned off.

[0030] The heat preservation device (11) can also be an electric heat preservation device, such as an electric heating pad.

[0032] When the humidity of the outer surface of the concrete (1) is too low, the remote control center (5) starts the water spray pump (15) through the remote controller (8), and the water spray pump (15) draws water from the heating water tank (14) and pumps it into the water spray pipe (121), and the water in the water spray pipe (121) is sprayed out through the water spray hole (121a) to increase the humidity of the outer surface of the concrete (1).

[0033] The moisturizing device (12) may also be a humidifier, the air outlet pipe of the humidifier extending between the heat insulating pad (9) and the outer surface of the concrete (1) to increase the humidity of the outer surface of the concrete (1).

[0034] The heating water pipe (111) is evenly distributed on the outer surface of the concrete (1) in an "S" shape to ensure uniform heating. The heating water pipe (111) is a rubber water pipe.

[0035] The heating water tank (14) is provided with an electric heating pipe (141), and the remote controller (8) obtains the instruction of the remote control center (5) to control the power on and off of the electric heating pipe (141). The heating water tank (14) is also provided with a water temperature sensor (142), and the water temperature sensor 142 is connected to the remote control center (5) via the thermometer host (4). Figure 1 Not shown.

[0036] The water temperature sensor 142 detects the water temperature in the heating water tank (14). When the water temperature is too low, the remote control center (5) controls the electric heating pipe (141) to be powered on via the remote controller (8) to heat the water in the heating water tank (14).

Pre-embedding of the probe of the internal temperature sensor (32): When pre-embedding, a supporting rod (31) such as a steel bar can be used as a support, and the temperature measuring lead wire is tied to the supporting rod (31) according to the longitudinal temperature measuring point distance. When pouring concrete, the supporting rod (31) with the temperature measuring lead wire tied is implanted into the concrete, and the probe of the internal temperature sensor (32) is at the temperature measuring point position. The lead wire plug is left outside the concrete (1) and covered with a plastic bag to avoid moisture and keep it clean. For ease of operation, the length of the lead wire left outside should be greater than 20 cm. When measuring temperature, press the power switch of the thermometer host (4), insert the plug of the temperature measuring lead wire into the socket of the thermometer host (4), and the temperature of the corresponding temperature measuring point can be displayed on the display screen of the thermometer host (4).

[0040] 2. Installation of circulating water cooling water pipe (2): After the main structure reinforcement is tied, the cooling water pipe (2) is installed between the main reinforcement. The cooling water pipe (2) is connected by a DN50 galvanized steel pipe. One end of the galvanized steel pipe serves as the circulating water inlet. The cooling water enters from the circulating water inlet and the flow rate is controlled by the cooling water pump (6). The circulating water outlet flows into the cooling water tank (7) for cooling. After the concrete is poured, the cooling water pipe (2) is wrapped inside the concrete.

[0041] 3. After the thermometer host (4) is turned on, the temperature measurement data can be sent to the remote control center (5) via wireless transmission. When the temperature detected exceeds the preset threshold, an alarm is triggered, and a command is sent to the remote controller (8) via wireless transmission to start the circulating cooling water pump (6) for cooling.
