Description

Technical Field

[0001] The invention belongs to the field of water hammer elimination tanks, and in particular relates to an intelligent water hammer elimination tank system. Background Art

[0002] As a key device for eliminating negative pressure water hammer in pressurized water delivery systems, water hammer eliminator plays a very important role in water hammer protection of water delivery systems. Its water hammer protection capability is determined by the calculation results of the transition process of the water delivery system and the performance of the equipment itself. The calculation results of the transition process are affected by many external factors. Often, the calculation results of each scientific research unit are different, which proves that the calculation results of the transition process are uncertain, and there can only be one reasonable parameter for a real water hammer eliminator. How to more effectively, completely and reasonably play the role of the water hammer eliminator requires us to conduct in-depth research. Summary of the invention

[0003] In view of this, the present invention aims to propose an intelligent water hammer elimination tank system to solve the problem that the calculation results of the transition process of water hammer protection in the prior art are affected by many external factors and the calculation results are uncertain.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] An intelligent water hammer elimination tank system comprises a tank body, an inner liner is arranged in the tank body, an air-filled space is arranged between the tank body and the inner liner, and the air-filled space is filled with compressed gas. The tank body is installed on one side of a pipeline, and the outlet end of the inner liner is connected to the pipeline. An electric regulating valve is arranged on the connecting pipeline between the inner liner and the pipeline, and the signal of the electric regulating valve is connected to a controller. The water bodies in the pipeline and the inner liner can compensate for each other. The controller controls the water-gas ratio inside the tank body by adjusting the pressure of the compressed gas, and controls the rate of the mutual compensation by adjusting the opening of the electric regulating valve. The controller can monitor the preset values ​​of the water-gas ratio and the rate, and reset the values ​​of the water-gas ratio and the rate multiple times by associating the medium pressure state in the pipeline, and the water-gas ratio and the rate are reset multiple times to gradually match the dynamic hydraulic model of the pipeline.

[0006] Furthermore, an air supply pipe and an air release pipe are arranged on the tank body, an air supply solenoid valve is arranged on the air supply pipe, and an air release solenoid valve is arranged on the air release pipe. An external air injection device can replenish compressed gas into the air supply space through the air supply pipe, and the air supply space can discharge compressed gas through the air release pipe. The signals of the air supply solenoid valve and the air release solenoid valve are respectively connected to the controller.

[0007] Furthermore, a pressure sensor is arranged in the air replenishing space, and the pressure sensor is used to detect the medium pressure in the air replenishing space, and the pressure sensor signal is connected to the controller.

[0008] Furthermore, a leak detection sensor is arranged in the air replenishing space, and the leak detection sensor is used to detect whether the inner tank leaks into the air replenishing space, and the leak detection sensor signal is connected to the controller.

[0009] Furthermore, a low liquid level emergency pipe and a high liquid level emergency pipe are respectively arranged in the inner tank, and a low liquid level emergency solenoid valve is arranged on the low liquid level emergency pipe, and a high liquid level emergency solenoid valve is arranged on the high liquid level emergency pipe. An external water injection device can fill water into the inner tank through the low liquid level emergency pipe, and the water in the inner tank can be discharged through the high liquid level emergency pipe. The signals of the low liquid level emergency solenoid valve and the high liquid level emergency solenoid valve are connected to the controller.

[0010] Furthermore, a liquid level meter is arranged in the inner tank, and the liquid level meter is used to detect the liquid level height in the inner tank, and the liquid level meter signal is connected to the controller.

[0011] Furthermore, the liquid level meter can push an alarm and handle the extreme abnormal phenomenon of the pipe body, and the method of pushing the alarm and handling the emergency is:

[0012] When the liquid level drops below the lowest level of the liquid level gauge, it indicates that the water replenishment process is extremely abnormal, there is a risk of the water in the pipe being emptied, and there is a risk of the gas in the tank entering the main pipeline through the liquid level gauge. The low liquid level emergency solenoid valve is closed and an alarm is sent;

[0013] When the liquid level rises to exceed the highest liquid level of the liquid level gauge, it indicates that the return water volume is extremely abnormal during the system pressure boost process, and there is a risk that the water in the tank can enter the inflation space through the liquid level gauge. Close the high liquid level emergency solenoid valve, cut off the channel, prevent water from entering the inflation space, and send an alarm.

[0014] Furthermore, the controller signals are connected to a host computer and a power module respectively, and a remote wireless communication module and a positioning module are respectively arranged on the host computer.

[0015] Furthermore, the preset values ​​of the water-gas ratio and the rate are that when water is initially passed through the pipeline, the water pressure in the pipeline is positive pressure. At this time, the water enters the inner tank, and the compressed gas pre-filled in the inflation space and the water pressure in the tank body are balanced through the flexible inner tank. The liquid level in the tank body is detected by a liquid level gauge, and it is checked whether the liquid level reaches the set value. If the current liquid level is higher than the set value, it means that the inflation is insufficient, and the air replenishing solenoid valve is started to inflate the inflation space and adjust the liquid level in the tank to the set value. Otherwise, the air releasing solenoid valve is opened to raise the liquid level and adjust it to the set value.

[0016] Furthermore, the medium pressure state in the associated pipeline is a state where the upstream water pump of the associated pipeline stops supplying water and the pipeline loses pressure, and the method for resetting the values ​​of the water-gas ratio and the rate is as follows:

[0017] 1. The pressure signal shows negative pressure, and the liquid level signal shows that it has not reached the warning low liquid level. The controller determines that the water replenishment rate in the tank is insufficient and needs to increase the opening of the electric regulating valve;

[0018] 2. If the pressure signal shows negative pressure and the liquid level signal shows that the liquid level value reaches or is lower than the low liquid level warning value, it is determined that the water volume in the tank is insufficient and it is necessary to adjust the water-gas ratio and deflate the air-filled space to increase the water volume;

[0019] 3. The pressure signal shows no negative pressure, and the liquid level signal shows that the liquid level data has not reached the low liquid level setting value, indicating that the water-gas ratio setting is abnormal, the water volume becomes larger, and the inflation space is inflated to increase the gas volume;

[0020] 4. If the pressure signal shows no negative pressure and the liquid level signal shows a value lower than the low liquid level warning value, it means that the water replenishment rate is too high and the opening of the electric regulating valve needs to be reduced;

[0021] 5. The pressure signal shows that the high pressure value exceeds the set value range, and the liquid level signal shows that it has not reached the set warning high liquid level, indicating that the return water rate is low and the opening of the electric control valve needs to be increased;

[0022] 6. If the pressure signal shows that the high pressure exceeds the set value and the liquid level signal exceeds the set warning high liquid level, it means that the initial water-gas ratio is abnormal and the gas volume is too small. Inflate the gas-filled space and increase the gas volume in the water-gas ratio.

[0023] 7. The pressure signal shows that the high pressure value is within the normal pressure increase range, and the liquid level signal exceeds the warning high liquid level, indicating that the water-gas ratio setting value is abnormal and the gas volume is small. Inflate the inflation space and increase the gas volume in the water-gas ratio;

[0024] 8. If the high pressure value of the pressure signal is within the set pressure boost range and the liquid level value of the liquid level signal is lower than the set high liquid level range, it means that the water-gas ratio is set abnormally and the gas volume is too large. Deflate the inflation space to increase the water volume.

[0025] Compared with the prior art, the intelligent water hammer eliminator system described in the present invention has the following beneficial effects: the system can conduct all-round monitoring of the working process of the water hammer eliminator and digitally present the working process of the water hammer eliminator; determine the working abnormality of the water hammer eliminator and push an alarm, so as to push a two-dimensional optimization solution for the water hammer eliminator based on physics and program; the performance of the water hammer eliminator can be continuously optimized and iterated to achieve the generation of the optimal performance solution for the water hammer eliminator; in the process of autonomously optimizing the water hammer eliminator, a hydraulic model based on the water hammer protection characteristics of the water hammer eliminator is autonomously generated and synchronously optimized, providing data and algorithm support for the digital twin of water hammer protection of the water supply system.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] like Figure 1 As shown, an intelligent water hammer elimination tank system includes a tank body 1, an inner liner 2 is arranged in the tank body 1, an air-filled space 3 is arranged between the tank body 1 and the inner liner 2, and the air-filled space 3 is filled with compressed gas. The tank body 1 is installed on one side of the pipeline 4, and the outlet end of the inner liner 2 is connected to the pipeline 4. An electric regulating valve 5 is arranged on the connecting pipeline between the inner liner 2 and the pipeline 4, and the signal of the electric regulating valve 5 is connected to the controller 6. The water bodies in the pipeline 4 and the inner liner 2 can compensate for each other. The controller 6 controls the water-gas ratio inside the tank body 1 by adjusting the pressure of the compressed gas, and controls the rate of the mutual compensation by adjusting the opening of the electric regulating valve 5. The controller 6 can monitor the preset values ​​of the water-gas ratio and the rate, and reset the values ​​of the water-gas ratio and the rate multiple times by associating the medium pressure state in the pipeline 4, and the water-gas ratio and the rate are reset multiple times to gradually match the dynamic hydraulic model of the pipeline 4.

[0035] An air supply pipe and an air release pipe are arranged on the tank body 1, an air supply solenoid valve 10 is arranged on the air supply pipe, and an air release solenoid valve 11 is arranged on the air release pipe. An external air injection device can supply compressed gas to the air supply space through the air supply pipe, and the air supply space can discharge compressed gas through the air release pipe. The air supply solenoid valve 10 and the air release solenoid valve 11 are respectively connected to the controller 6 by signals.

[0036] A pressure sensor 9 is set in the air replenishment space, and the pressure sensor 9 is used to detect the medium pressure in the air replenishment space. The signal of the pressure sensor 9 is connected to the controller 6. A leak detection sensor is set in the air replenishment space, and the leak detection sensor is used to detect whether the inner liner 2 leaks into the air replenishment space. The leak detection sensor signal is connected to the controller 6.

[0037] A low liquid level emergency pipe and a high liquid level emergency pipe are respectively arranged in the inner tank 2, and a low liquid level emergency solenoid valve 14 is arranged on the low liquid level emergency pipe, and a high liquid level emergency solenoid valve 13 is arranged on the high liquid level emergency pipe. An external water injection device can fill water into the inner tank 2 through the low liquid level emergency pipe, and the water in the inner tank 2 can be discharged from the high liquid level emergency pipe. The signals of the low liquid level emergency solenoid valve 14 and the high liquid level emergency solenoid valve 13 are connected to the controller 6. A liquid level gauge 12 is arranged in the inner tank 2, and the liquid level gauge 12 is used to detect the liquid level height in the inner tank 2. The signal of the liquid level gauge 12 is connected to the controller 6.

[0038] The liquid level gauge 12 can be used to push an alarm and perform emergency processing for extreme abnormal phenomena in the pipe body, and the method for pushing an alarm and performing emergency processing is as follows: (1) when the liquid level drops below the lowest liquid level of the liquid level gauge 12, it indicates that an extreme abnormality has occurred in the water replenishment process, there is a risk of the water in the pipe body being emptied, and there is a risk that the gas in the tank will enter the main pipeline 4 through the liquid level gauge 12. The low liquid level emergency solenoid valve 14 is closed and an alarm is sent; (2) when the liquid level rises to exceed the highest liquid level of the liquid level gauge 12, it indicates that an extreme abnormality has occurred in the return water volume during the system pressure increase process, and there is a risk that the water in the tank body 1 will enter the gas filling space 3 through the liquid level gauge 12. The high liquid level emergency solenoid valve 13 is closed to cut off the channel to prevent water from entering the gas filling space 3 and an alarm is sent.

[0039] The controller 6 signal is connected to the host computer 7 and the power supply 8 module respectively, and the host computer 7 is respectively provided with a remote wireless communication module and a positioning module, wherein the controller 6 is a PLC of the prior art, the positioning module is a GPS positioning or Beidou positioning module, the wireless communication module, the power supply 8 module and the solenoid valve and the sensor described in this embodiment are all prior art, and the specific signal is selected according to the working conditions, wherein the leakage monitoring of the leak detection sensor is the static data of the switch quantity, the solenoid valve is the dynamic data of the switch quantity, the pressure sensor 9 is the high-frequency pressure monitoring, the liquid level monitoring of the liquid level meter 12 is the analog monitoring data, and the electric control valve 5 is the digital monitoring data. After these monitoring data are received by the RTU data acquisition terminal, they are preliminarily processed according to the processing logic of each type of data, and then sent to the host computer 7, and the data are finally processed and applied.

[0040] The preset values ​​of the water-gas ratio and the rate are that when water is initially passed through the pipeline 4, the water pressure in the pipeline 4 is positive pressure, at which time the water enters the inner liner 2, and the compressed gas pre-filled in the inflation space 3 and the water pressure in the tank body 1 are balanced through the flexible inner liner 2. The liquid level in the tank body 1 is detected by the liquid level gauge 12, and it is checked whether the liquid level reaches the set value. If the current liquid level is higher than the set value, it means that the inflation is insufficient, and the air replenishing solenoid valve 10 is started to inflate the inflation space 3 and adjust the liquid level in the tank to the set value. Otherwise, the air releasing solenoid valve 11 is opened to raise the liquid level and adjust it to the set value.

[0041] After the initial water flow through pipeline 4 is completed, the system enters a steady-state monitoring state, the liquid level is within the range of the set value, and the regulating valve is within the set value opening range. If the leak detection sensor generates a water leakage signal during this period, a water leakage warning is sent to notify the water hammer tank for maintenance; if the leak detection sensor is normal, but the liquid level frequently changes beyond the set value range, a gas leakage alarm is pushed and the gas line is arranged for maintenance; if the leak detection signal is normal, the liquid level rises for a long time (more than 3 months), this state is determined to be normal, and the gas replenishment solenoid valve 10 is opened to replenish gas and adjust the liquid level to the set value.

[0042] The medium pressure state in the associated pipeline 4 is a state where the upstream water pump of the associated pipeline 4 stops water supply and the pipeline 4 loses pressure, and the method for resetting the values ​​of the water-gas ratio and the rate is as follows:

[0043] 1. The pressure signal shows negative pressure, and the liquid level signal shows that the warning low liquid level has not been reached. The controller 6 determines that the water replenishment rate in the tank 1 is insufficient, and the opening of the electric regulating valve 5 needs to be increased;

[0044] 2. If the pressure signal shows negative pressure and the liquid level signal shows that the liquid level value reaches or is lower than the low liquid level warning value, it is determined that the water volume in the tank 1 is insufficient and the water-gas ratio needs to be adjusted. The gas-filled space 3 needs to be deflated to increase the water volume.

[0045] 3. The pressure signal shows no negative pressure, and the liquid level signal shows that the liquid level data has not reached the low liquid level setting value, indicating that the water-gas ratio setting is abnormal, the water volume becomes larger, and the inflation space 3 is inflated to increase the gas volume;

[0046] 4. If the pressure signal shows no negative pressure and the liquid level signal shows a value lower than the low liquid level warning value, it means that the water replenishment rate is too high and the opening of the electric regulating valve 5 needs to be reduced;

[0047] 5. The pressure signal shows that the high pressure value exceeds the set value range, and the liquid level signal shows that it has not reached the set warning high liquid level, indicating that the return water rate is low and the opening of the electric regulating valve 5 needs to be increased;

[0048] 6. The pressure signal shows that the high pressure exceeds the set value, and the liquid level signal exceeds the set warning high liquid level, indicating that the initial water-gas ratio is abnormal and the gas volume is too small. Perform the inflation operation on the inflation space 3 to increase the gas volume in the water-gas ratio;

[0049] 7. The pressure signal shows that the high pressure value is within the normal pressure increase range, and the liquid level signal exceeds the warning high liquid level, indicating that the water-gas ratio setting value is abnormal and the gas volume is too small. Perform the inflation operation on the inflation space 3 to increase the gas volume in the water-gas ratio;

[0050] 8. The high pressure value of the pressure signal is within the set pressure boost range, and the liquid level value of the liquid level signal is lower than the set high liquid level range, indicating that the water-gas ratio setting is abnormal and the gas volume is too large. Deflate the inflation space 3 to increase the water volume.

[0051] The above 8 abnormal working conditions completely correspond to the deviation characteristics of the water-gas ratio and the opening setting value of the electric control valve 5 of the water hammer tank composed of the tank body 1 and the inner tank 2 in the transient working state. The controller 6 performs autonomous optimization and adjustment based on the above judgment logic, and then performs logical judgment and optimization during each pump stop process of the system. The optimization result is to reset the water-gas ratio and the opening of the control valve of the water hammer tank.

[0052] It can be seen from the monitoring and logical calculation process of the whole process of stopping the pump mentioned above that both the liquid level parameter and the opening parameter of the electric control valve 5 have an initial value. The initial value is the first data source, which is the calculation result of the transition process of different manufacturers or the initial design. The first operation of the system is carried out under high-frequency monitoring and clock synchronization technology, and the logical calculation is carried out under the same time reference, and then the initial value is corrected. After that, the initial value is optimized every time the system stops the pump. Finally, the longer the system runs, the more the optimized initial value meets the requirements of the system. In this process, the dynamic hydraulic model built into the system is optimized synchronously. When the initial value optimized by the system reaches an optimization deviation rate of less than 1% at a certain point in time, and there is no abnormal warning, it is considered that the autonomous optimization results of the system have met expectations, and its built-in hydraulic model has fully grown up and can be used for digital twins.

[0053] The intelligent water hammer elimination tank system proposed in this embodiment has the following features:

[0054] 1) It has data collection and processing functions, remote wireless communication functions, GPS positioning functions, and power supply 8 management functions;

[0055] 2) The system has the functions of water hammer elimination tank working status monitoring, abnormal early warning alarm, water hammer status analysis, water-gas ratio parameter optimization, inlet and outlet water impedance optimization, etc.

[0056] 3) State monitoring is divided into two modes: steady-state monitoring and transient monitoring. Steady-state monitoring is the norm, and transient monitoring is a wake-up mechanism under certain conditions. There are two wake-up modes: active wake-up and automatic wake-up. The difference between the two monitoring states lies in the different monitoring frequencies, data processing and storage, and data transmission mechanisms. Steady-state monitoring and transient monitoring only correspond to analog data. For steady-state monitoring, the data acquisition frequency is 10HZ. The acquisition terminal merges the currently collected analog data. If the value deviation of the data every 10 minutes is within the set range, it is merged into one data for upload. The data acquisition frequency of transient monitoring is 1000HZ. All the data are truly presented and uploaded. The acquisition terminal uses the stack method for cache processing and package upload;

[0057] 4) The system has an alarm and early warning function, which can give early warning alarms for abnormal operation of the intelligent water hammer elimination tank system and water hammer accidents. It has an emergency processing function, which can perform preset emergency processing for extreme working conditions of the water hammer elimination tank without background or manual intervention;

[0058] 5) The system has an autonomous optimization function. It uses a data iteration algorithm to compare the results of each transition process of the system operation with the preset simulation results, autonomously update the water-gas ratio setting value and the inlet and outlet water flow setting value of the water hammer elimination tank, continuously optimize and update, and autonomously find the water hammer tank setting parameters that best suit the current project conditions, so as to maximize the water hammer protection function of the water hammer tank to the theoretical maximum value.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

The pressure signal shows that the high pressure value exceeds the set value range, and the liquid level signal shows that it has not reached the set warning high liquid level, indicating that the return water rate is too low and the opening of the electric control valve (5) needs to be increased; 6. The pressure signal shows that the high pressure exceeds the set value, and the liquid level signal exceeds the set warning high liquid level, indicating that the initial water-gas ratio is abnormal and the gas volume is too small. Perform the inflation operation on the inflation space (3) to increase the gas volume in the water-gas ratio; 7. The pressure signal shows that the high pressure value is within the normal pressure increase range, and the liquid level signal exceeds the warning high liquid level, indicating that the water-gas ratio setting value is abnormal and the gas volume is too small. Perform the inflation operation on the inflation space (3) to increase the gas volume in the water-gas ratio; 8. If the high pressure value of the pressure signal is within the set pressure increase range and the liquid level value of the liquid level signal is lower than the set high liquid level range, it means that the water-gas ratio setting is abnormal and the gas volume is too large. Deflate the gas-filled space (3) to increase the water volume.
