Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a large-volume concrete cooling and water-passing device. Background Art

[0002] Cracks in concrete structures caused by concrete temperature stress are an important factor affecting the working performance and service life of large-volume concrete. Currently, in the construction of concrete dams, bridge piers, anchors, high-rise buildings and large wind power equipment foundations at home and abroad, it is necessary to control the maximum temperature, temperature gradient and cooling rate inside large-volume concrete. Burying cooling water pipes in large-volume concrete and cooling it with water is one of the most common and effective measures.

[0003] Currently, commonly used concrete temperature control systems generally utilize numerous sensors, control software, and PLC circuits, resulting in complex system principles and structures. A search revealed two large-volume concrete temperature control systems, published in Chinese Patent Publication Nos. CN 220318655 U and CN218181383U. Both systems utilize multiple sensors and control units for automated control. Configuring these systems is costly and requires specialized software and hardware engineers to build the control software and circuits. Furthermore, the required professional expertise of the operation and maintenance personnel is also high. However, some projects have relatively low temperature control design requirements, and adopting these temperature control systems would significantly increase construction costs. Utility Model Content

[0004] The utility model provides a large-volume concrete cooling and water supply device, which aims to achieve the basic requirements of large-volume concrete cooling and water supply while simplifying a large number of sensors, control software and PLC circuits, thereby reducing the development and procurement costs of equipment and software.

[0005] The utility model is realized by the following technical solution: a large volume concrete cooling water supply device, comprising:

[0006] A water inlet pipe, the water inlet pipe comprising a first water inlet pipe and a second water inlet pipe, the first water inlet pipe being provided with a first water pump, the second water inlet pipe being provided with a second water pump;

[0007] a return water pipe, the return water pipe comprising a first return water pipe and a second return water pipe, the first return water pipe being connected to the first water inlet pipe, the second return water pipe being connected to the second water inlet pipe, an inlet check valve being installed on the first water inlet pipe between the first water pump and the first return water pipe, and on the second water inlet pipe between the second water pump and the second return water pipe; and an outlet check valve being installed on the first return water pipe and the second return water pipe;

[0008] The cooling pipe is arranged in the bulk concrete, and both ends of the cooling pipe are respectively connected to the first water inlet pipe and the second water inlet pipe.

[0009] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0010] In this solution, the large-volume concrete cooling water supply device adopts a centralized water supply system consisting of an inlet pipe and a return pipe. Water enters the cooling pipe from one end of the cooling pipe to cool the concrete, then flows out from the other end of the cooling pipe and is discharged through the return pipe on the other branch inlet pipe. The water flow is reversed by controlling the on and off of the first water pump and the second water pump.

[0011] This solution uses the first and second water pumps to provide water pressure, and the water inlet and outlet check valves to control the direction of water flow, so that the water cannot flow back into the branch inlet pipe. Based on the hydraulic pressurized pipeline principle, the water flow rate and direction in the pipe can be changed. While meeting the basic requirements for water supply for large-volume concrete cooling, it can effectively simplify a large number of sensors, control software and PLC circuits, reducing the development and procurement costs of equipment and software.

[0012] Furthermore, the water inlet pipeline also includes a main water inlet pipe, the first water inlet pipe and the second water inlet pipe are both connected to the main water inlet pipe, and a water inlet valve is installed on the main water inlet pipe.

[0013] Beneficial effect: In this solution, the main water inlet pipe can connect the first water inlet pipe and the second water inlet pipe, and a water inlet valve is installed on the main water inlet pipe, so that the entire pipeline can be controlled by opening and closing the water inlet valve.

[0014] Furthermore, the return water pipeline also includes a main return water pipe, and the first return water pipe and the second return water pipe are both connected to the main return water pipe.

[0015] Beneficial effect: In this solution, the main return pipe can collect the water discharged from the first return pipe and the second return pipe in the same way, making the entire pipeline simpler.

[0016] Furthermore, a flow regulating package is installed on the main return pipe, and the flow regulating package can adjust the flow cross-sectional area of ​​the return pipe.

[0017] Beneficial effect: The flow regulating package in this solution adjusts the flow cross-sectional area of ​​the return pipe, thereby changing the water flow in the cooling pipe, and then facilitating the adjustment of the water flow according to actual conditions, such as the cooling area of ​​large-volume concrete.

[0018] Furthermore, the flow regulating package includes an inlet head, an outlet head and multiple connecting pipes, each of the connecting pipes is installed with a valve, one end of the inlet head and the outlet head are both closed ends, and the other end are both open ends, the two ends of the connecting pipes are respectively connected to the inlet head and the outlet head, and the open end of the inlet head is connected to the main return pipe.

[0019] Beneficial effect: The flow regulating package in this solution can change the flow cross-sectional area of ​​the return pipe by closing or opening the valves on some connecting pipes, thereby changing the water flow in the cooling pipe.

[0020] Furthermore, the flow cross-sectional area of ​​a single connecting pipe is smaller than the flow cross-sectional area of ​​the first water return pipe and the second water return pipe.

[0021] Beneficial effect: Such an arrangement can control the outflow speed of water in the first return pipe and the second return pipe not to be too large, thereby facilitating closing or opening of valves on some connecting pipes as needed.

[0022] Furthermore, the sum of the flow cross-sectional areas of the plurality of connecting pipes is 1-1.5 times the flow cross-sectional areas of the first water return pipe and the second water return pipe.

[0023] Beneficial effect: This solution can control the flow cross-sectional area of ​​the first return pipe and the second return pipe. When all the connecting pipes are in an open state, the flow cross-sectional area formed by all the connecting pipes is 1-1.5 times that of the first return pipe and the second return pipe, which can achieve the effect of rapid drainage.

[0024] Furthermore, a first water supply bag is connected between the first water inlet pipe and the cooling pipe, and a second water supply bag is connected between the second water inlet pipe and the cooling pipe; the first water supply bag and the second water supply bag each include a main pipe and multiple branch water pipes installed on the main pipe, each branch water pipe is installed with a branch water pipe valve, one end of the multiple branch water pipes is connected to the main pipe, and the other end of the multiple branch water pipes is connected to the cooling pipe, the main pipe of the first water supply bag and the main pipe of the second water supply bag are respectively connected to the first water inlet pipe and the second water inlet pipe.

[0025] Beneficial effects: In this solution, the first water supply bag and the second water supply bag can buffer the incoming water volume, and the water distribution pipes on the first water supply bag and the second water supply bag are connected to the cooling pipe. Since the water distribution pipe valve is installed on the water distribution pipe, the opening and closing of the single water distribution pipe can be controlled, thereby adjusting the water flow entering the cooling pipe, and then adjusting the cooling speed according to actual needs.

[0026] Furthermore, the cooling pipe is a serpentine curved pipe structure.

[0027] Beneficial effect: Such an arrangement can increase the contact area between the cooling pipe and the large volume of concrete, thereby improving the cooling efficiency and cooling uniformity.

[0028] Furthermore, it also includes a first water pump control switch and a second water pump control switch for controlling the start and stop of the first water pump and the second water pump. The first water pump control switch and the second water pump control switch both include an AC contactor and a time-controlled switch, and the AC contactor and the time-controlled switch are electrically connected.

[0029] Beneficial effect: The first water pump and the second water pump in this solution are respectively controlled by the first water pump control switch and the second water pump control switch, and the first water pump control switch and the second water pump control switch include a time-controlled switch and an AC contactor. In this way, the two water pumps can be set to work at different times through the time-controlled switch, thereby realizing the timed automatic reversal of the water flow in the cooling pipe.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example

[0042] like Figure 1 As shown, this embodiment provides a large-volume concrete cooling water supply device, comprising:

[0043] Water inlet pipe 1, the water inlet pipe 1 includes a main water inlet pipe 11, a first branch water inlet pipe 12, and a second branch water inlet pipe 13. The first branch water inlet pipe 12 and the second branch water inlet pipe 13 are both connected to the main water inlet pipe 11. In this embodiment, the first branch water inlet pipe 12, the second branch water inlet pipe 13 and the main water inlet pipe 11 are interconnected through a tee pipe. The main water inlet pipe 11 is installed with an inlet valve, which is a butterfly valve 14 in this embodiment. A first water pump 121 is installed on the first branch water inlet pipe 12, and a second water pump 131 is installed on the second branch water inlet pipe 13;

[0044] The return water pipeline 2 includes a main return water pipe 21, a first branch return water pipe 22 and a second branch return water pipe 23. The first branch return water pipe 22 is connected to the downstream side of the first branch water inlet pipe 12 through a tee pipe, and the second branch return water pipe 23 is connected to the downstream side of the second branch water inlet pipe 13 through a tee pipe. An inlet check valve 3 is installed on the first branch water inlet pipe 12 between the first water pump 121 and the first branch return water pipe 22 and on the second branch water inlet pipe 13 between the second water pump 131 and the second branch return water pipe 23. The inlet check valve 3 allows water entering from the main water inlet pipe 11 to flow only in one direction from the upstream water pump direction to the downstream direction; the first branch return water pipe 22 and the second branch return water pipe 23 are both installed with an outlet check valve 31. The outlet check valve 31 allows water to flow only in one direction from the water inlet pipe 1 to the first branch return water pipe 22 and the second branch return water pipe 23;

[0045] The cooling pipe 5 is arranged in the bulk concrete 4, and the two ends of the cooling pipe 5 are respectively connected to the first water inlet pipe 12 and the second water inlet pipe 13; in this embodiment, the cooling pipe 5 is a serpentine curved pipe structure, so that the contact area between the cooling pipe 5 and the bulk concrete 4 is larger and the cooling effect is better.

[0046] Combine Figure 1 and Figure 3 As shown, in another embodiment, a flow regulating package is installed on the main return pipe 21, and the flow regulating package can adjust the flow cross-sectional area of ​​the return pipe 2. Specifically: in this embodiment, the flow regulating package includes an inlet head 241, an outlet head 242 and a plurality of connecting pipes 243. In this embodiment, one end of the inlet head 241 and the outlet head 242 are both closed ends, and the other ends are both open ends. In this embodiment, the inlet head 241 and the outlet head 242 are arranged parallel to each other, and the open end of the inlet head 241 and the open end of the outlet head 242 are located on opposite sides, which is convenient for connecting with the pipeline and facilitating the arrangement of the pipeline position, making the arrangement between the pipelines simpler and making the pipeline arrangement simpler and neater.

[0047] Multiple connecting pipes 243 are distributed in sequence along the axial direction of the water inlet head 241 and the water outlet head 242. The two ends of the connecting pipe 243 are respectively connected to the water inlet head 241 and the water outlet head 242, and each connecting pipe 243 is installed with a valve 244. By closing or opening some valves 244, the flow cross-sectional area of ​​the return water pipeline 2 can be changed, thereby changing the water flow rate in the cooling pipe 5; the open end of the water inlet head 241 is connected to the main return water pipe 21, and the open end of the water outlet head 242 discharges and collects the return water through the connecting pipe.

[0048] In this embodiment, the flow cross-sectional area of ​​a single connecting pipe 243 is smaller than the flow cross-sectional area of ​​the first return pipe 22 and the second return pipe 23, and the sum of the flow cross-sectional areas of multiple connecting pipes 243 is 1-1.5 times the flow cross-sectional area of ​​the first return pipe 22 and the second return pipe 23.

[0049] In another embodiment, combined with Figure 1 and Figure 2 As shown, a first water supply bag 122 is connected between the first water inlet pipe 12 and the cooling pipe 5, and a second water supply bag 132 is connected between the second water inlet pipe 13 and the cooling pipe 5; the first water supply bag 122 and the second water supply bag 132 each include a main pipe 1221 and multiple branch water pipes 1222 installed on the main pipe 1221, and each branch water pipe 1222 is installed with a branch water pipe 1222 valve 244. In this embodiment, the branch water pipe 1222 valve 244 is a ball valve 1223. By closing or opening part of the ball valve 1223, it is convenient to adjust the water flow rate and cooling speed in the cooling pipe 5 according to actual needs.

[0050] Multiple branch water pipes 1222 are distributed in sequence along the axial direction of the main pipe 1221, and one end of the multiple branch water pipes 1222 is connected to the main pipe 1221, and the other end of the multiple branch water pipes 1222 is connected to the cooling pipe 5. In this embodiment, the branch water pipes 1222 in the first water supply bag 122 and the branch water pipes 1222 in the second water supply bag 132 are respectively connected to the two ends of the cooling pipe 5; the main pipe 1221 of the first water supply bag 122 and the main pipe 1221 of the second water supply bag 132 are respectively connected to the first water inlet pipe 12 and the second water inlet pipe 13. Specifically: in this embodiment, one end of the first water supply bag 122 and the second water supply bag 132 is an open end, and the other end is a closed end. The open ends of the first water supply bag 122 and the second water supply bag 132 are respectively connected to the first water inlet pipe 12 and the second water inlet pipe 13.

[0051] The specific implementation process is as follows:

[0052] When the first water pump 121 is turned on and the second water pump 131 is turned off, the cooling water enters the first branch water inlet pipe 12 from the main water inlet pipe 11, and then passes through the tee pipe, so that part of the cooling water is directly discharged from the first return water pipe 22, and the other part of the cooling water enters the first water supply bag 122, and is divided by the water distribution pipe 1222 of the first water supply bag 122 before entering the cooling pipe 5 to cool the large volume concrete 4. The return water from the cooling pipe 5 enters the second water supply bag 132, and then flows back into the rear section of the second branch water inlet pipe 13. Due to the obstruction of the water inlet check valve 3 on the second branch water inlet pipe 13, the water flow cannot enter the front section of the second branch water inlet pipe 13, and can only enter the second return water pipe 23 through the tee pipe for discharge;

[0053] When the second water pump 131 is turned on and the first water pump 121 is turned off, the cooling water enters the second branch water inlet pipe 13 from the main water inlet pipe 11, and then passes through the tee pipe, so that part of the cooling water is directly discharged from the second branch return pipe 23, and the other part of the cooling water enters the second water supply bag 132, and after being divided by the water distribution pipe 1222 of the second water supply bag 132, enters the cooling pipe 5 to cool the large volume concrete 4. The return water from the cooling pipe 5 enters the first water supply bag 122, and then flows back into the rear section of the first branch water inlet pipe 12. Due to the obstruction of the water inlet check valve 3 on the first branch water inlet pipe 12, the water flow cannot enter the front section of the first branch water inlet pipe 12 and can only enter the first branch return pipe 22 through the tee pipe for discharge. In this process, the water flow in the cooling pipe 5 is reversed, thereby facilitating timely heat exchange and improving cooling efficiency. The return water can also be recycled through the water inlet pipe again, saving water resources.

[0054] Combine Figure 4As shown, in another embodiment, a large-volume concrete cooling water supply device also includes a first water pump 121 control switch and a second water pump 131 control switch for controlling the start and stop of the first water pump 121 and the second water pump 131. The first water pump 121 control switch and the second water pump 131 control switch both include an AC contactor 1232 and a time-controlled switch 1231. The AC contactor 1232 and the time-controlled switch 1231 are electrically connected to each other, and the first water pump 121 and the second water pump 131 are respectively connected to the first water pump 121 control switch through cables.

[0055] In this embodiment, the first water pump 121 and the second water pump 131 are controlled by the first water pump 121 control switch and the second water pump 131 control switch, respectively. The two water pumps are set to operate at different times via a timer switch 1231, thereby achieving timed, automatic reversal of the water flow within the cooling pipe 5. The large-volume concrete cooling water supply device of the present invention utilizes a combination of pipes, check valves, and water pumps to achieve cooling water reversal. Controlled by the timer switch 1231, this automated cooling reversal eliminates the need for human intervention. Adjustment of the water flow rate is centrally controlled by opening and closing the flow control valve 244, facilitating ease of operation.

[0056] The utility model provides a large-volume concrete cooling water supply device with low requirements for water sources. Water can be taken from rivers, ponds, pools, water tanks or municipal pipelines according to actual on-site conditions and temperature control technical requirements, and has a wide range of usage scenarios.

[0057] The components of the large-volume concrete cooling water supply device of the present invention include a water pump, a pipe, a check valve, a butterfly valve 14, a ball valve 1223, various joints and switches, etc. All components are common components on the market and can be installed by a plumber with certain professional skills, which is convenient to install.

[0058] The utility model discloses a large-volume concrete cooling water supply device that uses a water inlet pipe and a return pipe for centralized water supply. The water is then distributed by a water supply bag into a curved pipe for concrete cooling. The water flow pressure is provided by a water pump, and the water flow direction is controlled by a check valve. Based on the hydraulic pressure pipeline principle, the water flow rate and water flow direction in the pipe are changed. While achieving the basic requirements of large-volume concrete cooling water supply, a large number of sensors, control software and PLC circuits are simplified, thereby reducing the development and procurement costs of equipment and software.
