Description

Technical Field

[0001] This application relates to the field of underground engineering, and more specifically, to a cooling water tank. Background Technology

[0002] During the construction and operation of underground projects, heat is continuously generated due to the relatively enclosed space, equipment operation, and personnel activities. If effective cooling is not carried out in time, excessively high temperatures will seriously affect the normal operation of equipment, the work efficiency and comfort of personnel, and may even cause safety hazards. Therefore, there is an urgent need for cooling in underground projects.

[0003] Currently, many underground projects use cooling water systems with cooling pools to achieve cooling. However, existing cooling pools have obvious drawbacks. During operation, when the cooling water temperature rises, it is often necessary to manually drain the hot water. This process not only consumes manpower but also leads to a large waste of water resources. In the current context of increasingly scarce water resources, this undoubtedly greatly increases the operating costs of underground projects and does not conform to the concept of sustainable development.

[0004] Therefore, how to provide a cooling water tank that can be automatically controlled and saves cooling water has become a technical problem that needs to be solved in this field. Utility Model Content

[0005] In view of this, this application proposes a cooling water tank.

[0006] According to this application, a cooling water tank is proposed, comprising: a water tank for providing cooling water and cooling the cooling water; a cooling water circulation system for supplying cooling water from the water tank to spaces requiring cooling and returning the cooling water to the water tank; a cooling system disposed inside and / or outside the water tank for cooling the water inside the water tank; and a control system disposed outside the water tank and electrically connected to the cooling system and the cooling water circulation system for monitoring the water temperature inside the water tank and controlling the opening or closing of the cooling system inside the water tank.

[0008] Preferably, the active cooling device includes a stirring section disposed at the bottom of the water tank and a blowing section disposed at the top of the water tank, wherein the height of the blowing section is higher than the highest water level in the water tank.

[0009] Preferably, the auxiliary cooling device includes: a drain pipe, which is located at the bottom of one side of the water tank and is connected to the water tank and the cooling water circulation system through a pipe, for discharging the returned cooling water; and a water supply pipe, which is located at the top of one side of the water tank and is connected to the water tank through a pipe, for replenishing the cooling water in the water tank.

[0010] Preferably, the water supply pipe includes a main water inlet pipe, an automatically controlled water inlet pipe, and a manually controlled water inlet pipe, wherein each of the water inlet pipe, the automatically controlled water inlet pipe, and the manually controlled water inlet pipe is equipped with a manual valve; the automatically controlled water inlet pipe is also equipped with a level float valve, which is located inside the water tank and at the highest water level line.

[0011] Preferably, the cooling water circulation system includes: a water supply pipe located at the bottom of one side of the water tank; and a return water pipe located at the top of one side of the water tank. The return water pipe is connected to the drain pipe of the auxiliary cooling device in the cooling system via a pipeline, and a manual valve is installed in the middle of the pipeline.

[0012] Preferably, both the water supply pipe and the return pipe are equipped with manual valves.

Under normal operation of the cooling water tank, no manual operation is required, which can avoid the large consumption of water resources and the increase in the operating cost of the cooling water tank due to improper operation by the staff.

[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0018] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application, and the illustrative embodiments and descriptions thereof are used to explain this application. In the drawings:

[0019] Figure 1 This is a schematic diagram of a cooling water tank according to a preferred embodiment of this application. Detailed Implementation

[0020] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, according to this application, a cooling water tank is proposed, comprising: a water tank 1 for providing cooling water and cooling the cooling water; a cooling water circulation system for supplying the cooling water inside the water tank 1 to the space requiring cooling and returning the cooling water to the water tank 1; a cooling system disposed inside and / or outside the water tank 1 for cooling the water inside the water tank 1; and a control system disposed outside the water tank 1 and electrically connected to the cooling system and the cooling water circulation system for monitoring the water temperature inside the water tank 1 and controlling the opening or closing of the cooling system inside the water tank 1.

[0022] The aforementioned cooling water tanks should be installed in appropriate locations, such as near equipment rooms in underground projects, close to water sources (e.g., underground wells or municipal water supply pipelines), or in well-ventilated areas. In actual projects, the specific installation location needs to be comprehensively evaluated and optimized based on factors such as the type of underground project (e.g., subway stations, underground shopping malls, underground parking lots, tunnels), its scale, layout, and geological conditions, to achieve efficient operation of the cooling water tanks and safe and economical operation of the overall project.

[0023] The aforementioned water tank 1 can be either open at the top or closed at the top, depending on the water quality requirements and the location of the area. In this application, an open-top water tank 1 is used as an example. The material of the aforementioned water tank 1 can be selected according to the usage scenario, for example, it can be at least one of reinforced concrete, stainless steel, or fiberglass.

[0024] The aforementioned pool 1 provides a storage and circulation facility for cooling water, enabling the recycling of water resources and reducing operating costs.

[0025] The aforementioned cooling water circulation system supplies cooling water from pool 1 to spaces requiring cooling (such as equipment rooms) and then returns the cooling water to pool 1. As the cooling water continuously flows back, the water temperature in pool 1 continuously rises.

[0026] The cooling system described above can be activated when the water supply temperature is higher than the set value. The set value is usually 1°C lower than the allowable water supply temperature. The specific set value can be adjusted according to the actual situation to reduce the water temperature in the water tank 1.

[0027] The aforementioned control system can monitor the water supply temperature and control the cooling system to turn on or off.

[0028] The cooling water tank proposed in this application can monitor the water temperature of the cooling water in the tank in real time and automatically control the opening or closing of the cooling system according to the water temperature change. Under normal operation of the cooling water tank, no manual operation is required, which can avoid the large consumption of water resources and the increase in the operating cost of the cooling water tank due to improper operation by the staff.

[0029] According to a preferred embodiment of this application, the cooling system may include an active cooling device, which may be installed inside the water tank 1. The active cooling device may include a stirring section 2 installed at the bottom of the water tank 1 and a blowing section 3 installed at the top of the water tank 1, wherein the height of the blowing section 3 is higher than the highest water level in the water tank 1. When the water supply temperature reaches the activation temperature of the cooling system, the active cooling device is activated, and the water temperature inside the water tank 1 is lowered by the stirring section 2 at the bottom of the water tank 1 and the blowing section 3 above the water tank 1. The blowing section 3 may be a fan or blower. Using an active cooling system can minimize the need to replace the water inside the water tank 1 when the water temperature exceeds the set value, thus avoiding a large waste of water resources.

[0030] The aforementioned cooling system also includes an auxiliary cooling device, which can be installed inside the water tank 1. The auxiliary cooling device includes: a drain pipe 4, located at the bottom of one side of the water tank 1 and connected to the water tank 1 and the cooling water circulation system via a pipeline, used to discharge the returned cooling water; and a water supply pipe 5, located at the top of one side of the water tank 1 and connected to the water tank 1 via a pipeline, used to replenish the cooling water in the water tank 1. When the active cooling system is insufficient to lower the water temperature inside the water tank 1 below the activation temperature of the cooling system, the auxiliary cooling device activates, directly draining the returned cooling water into the drain pipe 4. This prevents this water from entering the water tank 1 and causing a further increase in the internal water temperature, and also saves the amount of water that needs to be replenished inside the water tank 1, thus conserving water resources. The water supply pipe 5 is connected to the city's water supply pipeline or an underground well pipe. The direct discharge of cooling water into the drain pipe 4 causes a drop in the liquid level in the water tank 1, at which point the water supply pipe 5 begins to replenish the water tank 1 with low-temperature water. When the water temperature in pool 1 is lower than the start-up temperature of the cooling system (usually 5°C lower than the cooling water supply temperature), the cooling system is shut down. At least one manual valve 6 is provided on the drain pipe 4. In this application, two valves are provided. One manual valve 6 is located on the outside of pool 1 and is normally kept closed. It is opened when the water in pool 1 needs to be replaced or the inside of pool 1 needs to be cleaned. The other manual valve 6 is located at the far end of the pipe connected to the cooling water circulation system and is normally kept open. The direction of the cooling water in the return water pipe 9 is controlled by the electric valve 10 on the return water pipe 9.

[0031] Preferably, the water supply pipe 5 may include a main water inlet pipe 51, an automatically controlled water inlet pipe 52, and an automatically controlled water inlet pipe 53. Each of the water inlet pipes, the automatically controlled water inlet pipe 52, and the manually controlled water inlet pipe 53 is equipped with a manual valve 6. The automatically controlled water inlet pipe 52 is also equipped with a level float valve 7, which is located inside the water tank 1 and at the highest water level. Under normal operation of the cooling water tank, the manual valves 6 on the main water inlet pipe 51 and the automatically controlled water inlet pipe 52 are open, while the manual valve 6 on the manually controlled water inlet pipe 53 remains closed. The manual valve 6 on the manually controlled water inlet pipe 53 is only opened in the event of a malfunction of the level float valve 7. The automatically controlled water inlet pipe 52 and the manually controlled water inlet pipe 53 can be located on the same horizontal plane or vertically. When the cooling water tank is operating normally, when the liquid level in the water tank 1 drops, the liquid level float valve 7 will automatically open to replenish the cooling water in the water tank 1 in time. When the liquid level reaches the highest water level (the position of the liquid level float valve 7), the liquid level float valve 7 will automatically close to stop replenishing water to the water tank 1.

[0032] To continuously supply cooling water to the underground space, the cooling water circulation system preferably includes: a supply pipe 8, which is located at the bottom of one side of the water tank 1 to prevent the supply pipe 8 from being affected by the drop in the liquid level inside the water tank 1; and a return pipe 9, which is located at the top of one side of the water tank 1 to prevent cooling water from flowing back through the return pipe 9; the return pipe 9 is connected to the drain pipe 4 of the auxiliary cooling device in the cooling system via a pipe, and a manual valve 6 is installed in the middle of the pipe.

[0033] Preferably, both the water supply pipe 8 and the return pipe 9 are equipped with manual valves 6.

[0034] Under normal circumstances, the manual valves 6 on the water supply pipe 8, return pipe 9, and the intermediate pipe between the drain pipe 4 and the return pipe 9 are all kept open. An electric valve 10 is installed on the return pipe 9. The electric valve 10 is installed at the junction of the intermediate pipe between the drain pipe 4 and the return pipe 9, and is used to control the flow of cooling water into the water tank 1 or into the drain pipe 4. The electric valve 10 is a three-way electric valve.

[0035] To automate the control of the cooling water tank and reduce manual operation, the control system preferably includes: a temperature sensing device 11, which is installed on the water supply pipe 8 of the cooling water circulation system to monitor the temperature of the cooling water in the tank 1; and a temperature control device 12, which controls the operation of the cooling water circulation system and the cooling system based on the temperature changes of the temperature sensing device 11. The temperature sensing device 11 can be at least one of a thermocouple, a resistance temperature detector (RTD), or a thermistor, and can be selected as needed.

[0036] The aforementioned temperature sensing device 11 can monitor the water temperature in the water supply pipe 8 at any time and transmit the water temperature to the temperature control device 12 through a wire. When the water temperature is lower than the set value of the cooling system, the cooling system will not start; when the water temperature is higher than the set value, the cooling system will start.

[0037] To provide power to the cooling water tank, preferably, the cooling water tank also includes a power supply device 13, which is located outside the water tank 1 and electrically connected to the cooling water circulation system, cooling system, and control system via a signal transmission line 14. The power supply device 13 is electrically connected to the mains power supply, and the temperature control device 12 is located inside the power supply device 13. To ensure the cooling water tank can operate normally in case of a malfunction, a battery-powered audible and visual alarm can also be installed inside the power supply device 13 to remind staff to manually control the cooling water tank.

[0038] The working process of the cooling water tank proposed in this application is as follows:

[0039] 1) As high-temperature cooling return water continuously enters the water tank 1, the water temperature in the water tank 1 continuously rises, which in turn leads to a continuous rise in the cooling water supply temperature. When the cooling water supply temperature reaches the set cooling system start-up temperature (the set temperature is usually 1°C lower than the allowable cooling water supply temperature, and the specific set temperature can also be adjusted according to the actual situation), the temperature signal of the temperature sensing device 11 is sent to the temperature control device 12 in the power supply device 13 through signal transmission, and the blowing section 3 and the stirring section 2 are activated by the temperature control device 12. When the blower 3 and the agitator 2 are in the open state, they still cannot prevent the cooling water supply from reaching the set cooling system start-up temperature. The temperature signal of the temperature sensing device 11 is sent to the temperature control device 12 in the power supply device 13 through the signal transmission line 14. The temperature control device 12 interlocks and adjusts the electric valve 10 set on the cooling water return pipe 9 to change the high-temperature cooling return water discharged into the water tank 1 to be discharged into the drainage system through the drain pipe 4. At this time, the water level in the water tank 1 drops, triggering the liquid level float valve 7 set on the water supply pipe 5 to open and start to replenish low-temperature raw water into the water tank 1 so as to achieve the cooling water supply temperature meeting the requirements for normal operation of the cooling water system.

[0040] 2) When the cooling water supply reaches the set cooling system stop temperature (the set temperature is usually 5°C lower than the allowable cooling water temperature, and the specific set temperature can also be adjusted according to the actual situation), the temperature signal of the temperature sensing device 11 is sent to the temperature control device 12 in the power supply device 13 through the signal transmission line 14. The temperature control device 12 interlocks and adjusts the electric valve 10 set on the cooling water return pipe 9 to change the high-temperature cooling return water discharged into the drainage system in the reservoir to be discharged into the water tank 1 through the cooling water return pipe. At this time, the water level in the water tank 1 rises, triggering the liquid level float valve 7 set on the water supply pipe 5 to close and stop the replenishment of low-temperature raw water into the water tank 1. The temperature of the actual water tank 1 is automatically controlled, and the water supply and drainage are automatically adjusted to reduce the large consumption of water resources and reduce the later operation cost of the underground project.

[0041] 3) In case of special circumstances (such as damage to signal transmission line 14, failure of control components within power supply unit 13, power outage, etc.), the battery-powered audible and visual alarm within power supply unit 13 will sound an alarm to alert nearby personnel to handle the problem on-site. Depending on the situation, personnel can manually open or close the blower section 3 and the agitator section 2 within power supply unit 13, and adjust the electric valve 10. The manual valves 6 installed on the cooling water supply pipe 8, cooling water return pipe 9, water replenishment pipe 5, and drain pipe 4 are quick-opening and closing operable valves for convenient operation.

[0042] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this invention.
