Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a large-volume concrete water-cooling system and an automatic control method thereof. Background Technique

[0002] Large-volume concrete projects are widely used in the field of construction engineering, especially in industries such as water conservancy and hydropower, road and bridge, etc. To avoid temperature stress in large-volume concrete due to excessive internal temperature and develop into temperature cracks, thereby affecting the structural safety, stability and durability. It is necessary to aim at reducing the internal temperature of concrete. By arranging water pipes in the concrete and using the cooling water flowing in the water pipes to take away the hydration heat, the effect of cooling the concrete is achieved. The cooling water pipes can not only reduce the maximum temperature in the early stage, reduce the temperature peak value, but also reduce the internal and external temperature difference and temperature gradient, and the effects of peak reduction and difference reduction are remarkable.

[0003] If the temperature difference between the cooling water temperature and the temperature after concrete pouring is too large, it is easy to cause cracks in the concrete. If the temperature difference between the cooling water temperature and the temperature after concrete pouring is too small, it cannot effectively play the role of peak reduction and cooling of the concrete. Therefore, it is very important to adjust the cooling water temperature according to the temperature change of the concrete. In traditional construction, it is necessary to arrange special personnel to take turns to measure the temperature for 24 hours in three shifts, and calculate the cooling water temperature according to the measured data. This method has low operation efficiency and high error rate. Therefore, we propose a large-volume concrete water-cooling system and an automatic control method thereof to solve the above problems. Summary of the Invention

[0032] In order to solve the problems of low efficiency and high error rate in manually calculating the water temperature of cooling water, the present invention provides a large-volume concrete water-cooling system and its automatic control method. The following further describes the large-volume concrete water-cooling system and its automatic control method with specific embodiments in conjunction with the accompanying drawings.

[0033] Refer to Figures 1 to 2 As shown, a large-volume concrete water-cooling system includes:

[0034] Cooling water pipes arranged inside the large-volume concrete;

[0035] A refrigeration system for cooling the cooling water and then introducing it into the cooling water pipes. The refrigeration system is connected to the cooling water pipes;

[0036] A water replenishing device for supplying cooling water to the refrigeration system. The water replenishing device is connected to the refrigeration system;

[0037] A temperature measuring system for monitoring the temperature of the large-volume concrete and the temperature of the cooling water cooled by the refrigeration system, and obtaining first data and second data respectively; and

[0038] A control device for obtaining the first data and the second data in real time and controlling the refrigeration system according to the difference between the first data and the second data to keep the difference within a preset difference range. The temperature measuring system and the refrigeration system are both connected to the control device.

[0039] Specifically, the cooling system further includes a cloud server. The cloud server is communicatively connected to the control device, and the control device can record the received data for the operator to view.

[0040] Among them, the refrigeration system includes a heat preservation water tank, a refrigeration device, a chilled water storage tank, and a pressure pump. Among them: the heat preservation water tank is simultaneously connected to the water replenishing device and the refrigeration device; the chilled water storage tank is simultaneously connected to the refrigeration device and the pressure pump; the pressure pump is respectively connected to the heat preservation water tank and the cooling water pipes through a first valve and a second valve; the control device is controllably connected to the first valve and the second valve, and is used to control the first valve to open and the second valve to close when the difference is not within the predetermined difference range, so that the refrigeration system circulates for refrigeration to change the magnitude of the second data until the difference is within the preset difference range, and then controls the first valve to close and the second valve to open.

[0041] Specifically, the heat preservation water tank is connected to the refrigeration device through a third water delivery pipe, and a first circulation pump is installed on the third water delivery pipe. The refrigeration device is connected to the chilled water storage tank through a fourth water delivery pipe, and a second circulation pump is installed on the fourth water delivery pipe. Through the first circulation pump, the second circulation pump, and the pressure pump, the cooling water can flow.

[0042] Further, the cooling water pipe is connected to the pressure pump through the fifth water delivery pipe. The second valve is installed on the fifth water delivery pipe. A steering valve is installed at one end of the fifth water delivery pipe close to the cooling water pipe, and its function is to change the flow direction of the cooling water. In the mass concrete, the flow direction of the cooling water needs to be changed at regular intervals according to the standard. When the cooling water passes through the steering valve, the flow direction is changed by controlling the opening and closing of the corresponding valve of the steering valve (the structures of the steering valve and the cooling water pipe are both prior arts and will not be elaborated too much).

[0043] The water replenishing device is controlled by the control device to replenish cooling water into the heat preservation water tank to a preset liquid level. The first circulation pump can be controlled to transport the cooling water in the heat preservation water tank to the refrigeration equipment. The second circulation pump can be controlled to transport the cooling water in the refrigeration equipment to the chilled water storage tank.

The control device can obtain the third data and the fourth data in real time, and control the three-way valve to change the flow direction of the cooling water according to whether the third data is greater than / less than the fourth data, so that the cooling water flowing out of the cooling water pipe is discharged through the drain pipe / returned to the heat preservation water tank through the second water delivery pipe.

[0049] By adopting the above design, the control device can automatically judge whether the cooling water flowing out of the cooling water pipe is discharged / returned for reuse according to the temperature measured by the third temperature measurement device and the fourth temperature measurement device. The automatic control efficiency is high, and the discharged cooling water can be used for construction water without waste.

[0054] Through the control device, it can automatically judge whether there is a leakage phenomenon in the cooling water pipe according to the inlet flow velocity of the cooling water measured by the first flow velocity measurement device and the outlet flow velocity of the cooling water measured by the second flow velocity measurement device.

[0055] Furthermore, the temperature measurement system further includes a fifth temperature measurement device. The fifth temperature measurement device is arranged at one end where the cooling water pipe is connected to the fifth water delivery pipe, and is used to monitor the temperature of the cooling water when it flows into the cooling water pipe;

[0056] By adopting the above design, the temperature of the cooling water when it flows into the cooling water pipe can be monitored. By comparing it with the temperature of the cooling water in the chilled water storage tank measured by the first temperature measurement device, it can be known how much temperature is lost during the process of the cooling water flowing from the chilled water storage tank to the cooling water pipe. Furthermore, the control device can more accurately control the temperature of the cooling water cooled by the refrigeration equipment.
