All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figures 1 to 4, the embodiment of the present invention provides a high-pressure water tank electronic control system, including: a PLC electronic control system, including: an opening and closing cover oil cylinder, a locking and unlocking oil cylinder, an oil pump motor and a PLC control panel; the opening and closing cover oil cylinder is used to drive the cover on the high-pressure water tank to open or close; it also includes a cover opening solenoid valve and a cover closing solenoid valve connected to the oil circuit of the opening and closing cover oil cylinder; the cover opening solenoid valve and the cover closing solenoid valve are electrically connected to the cover opening button and the cover closing button respectively; the locking and unlocking oil cylinder is used to drive the locking ring on the cover to lock or unlock the cover; it also includes a locking solenoid valve and an unlocking solenoid valve connected to the oil circuit of the locking and unlocking oil cylinder; the locking solenoid valve and the unlocking solenoid valve are electrically connected to the locking button and the unlocking button respectively; the oil pump motor is used to supply oil to the opening and closing cover oil cylinder and the locking and unlocking oil cylinder; the PLC control panel is equipped with an opening button, a cover closing button, a locking button, an unlocking button, a pressurization start button, a pressurization stop button, and a pressurization stop button. Water start button and water filling stop button; pressure control measurement system, including: intelligent instrument, PC computer, high-pressure electric ball valve, high-pressure solenoid valve, booster pump motor, frequency converter, pressure sensor and water filling pump; the intelligent instrument is electrically connected to the PC computer, high-pressure electric ball valve, high-pressure solenoid valve, booster pump motor, frequency converter, pressure sensor and PLC control panel respectively; high-pressure electric ball valve, used to relieve the pressure in the high-pressure water tank; high-pressure solenoid valve, used to open and close the pressurized pipeline in the high-pressure water tank; booster pump motor, used to pressurize the inside of the high-pressure water tank; also includes a pressure start button and a pressure stop button electrically connected to the booster pump motor; frequency converter, used to adjust the speed of the booster pump motor; pressure sensor, used to detect the pressure value in the high-pressure water tank; water filling pump, used to add water to the inside of the high-pressure water tank; also includes a water filling start button and a water filling stop button electrically connected to the water filling pump.

[0047] It specifically includes the following parts:

[0048] 1. Power supply:

[0049] The high-pressure water tank electrical system uses an AC 380V power supply, and the total equipment power is 5kW.

[0050] 2. Electrical control system:

[0051] The main controller in the electrical control system adopts Siemens S7-200 Smart programmable controller, and the AC contactors that control the oil pump motor and booster pump motor adopt Schneider brand products, which can improve the reliability of the system.

[0052] The pressure measurement and control system uses the intelligent instrument AI-719P of Yudian Company and the Yudian AIFCS (2.0) measurement and control software installed on the PC.

[0053] The action of the high-pressure water tank cover is completed by the hydraulic system. When the hydraulic system is working, first press the oil pump start button on the control cabinet panel, and the oil pump motor will work. After a certain period of time, observe whether the oil pressure gauge pressure is normal.

[0054] The electrical system controls the lid opening, closing, locking, and unlocking operations by switching four solenoid valves on and off. A manual / automatic selector switch is mounted on the electrical control panel. When the selector switch is in the manual position, pressing the lid closing button energizes the lid closing solenoid, pushing the lid opening and closing cylinder forward, and closing the lid. Releasing the lid closing button de-energizes the solenoid, and the lid opening and closing cylinder stops. If the lid closing button is held down, the lid closing operation is complete, and upon hitting the lid closing limit, the solenoid de-energizes, and the lid opening and closing cylinder stops.

[0055] Pressing the lock button energizes the locking electromagnet, pushing the locking and unlocking cylinders outwards, and locking is performed. Releasing the lock button de-energizes the electromagnet, and the locking and unlocking cylinders stop. If the lock button is pressed continuously, the locking action is completed, and when the locking limit is reached, the electromagnet de-energizes, and the locking and unlocking cylinders stop.

[0056] Pressing the unlock button energizes the unlocking electromagnet, causing the locking and unlocking cylinder to retract and unlock. Releasing the unlock button de-energizes the electromagnet, stopping the locking and unlocking cylinder. If the unlock button is pressed continuously, the unlocking action is complete, and when the unlocking limit is reached, the electromagnet de-energizes, and the locking and unlocking cylinder stops.

[0057] Pressing the cover-opening button energizes the electromagnet, retracts the cover-opening cylinder, and begins the cover-opening action. Releasing the cover-opening button de-energizes the electromagnet, and the cover-opening cylinder stops. If the cover-opening button is pressed continuously, the cover-opening action is completed, and when the cover-opening limit is reached, the electromagnet de-energizes, and the cover-opening cylinder stops.

[0058] When the selector switch is in the automatic mode position: Pressing the close button energizes the closing solenoid, pushing the cover open / close cylinder forward, and closing the lid. When the cover closes, the solenoid de-energizes, and the cover open / close cylinder stops. After a delay, the locking solenoid energizes, pushing the lock / unlock cylinder forward, and locking the lid. When the lock / unlock limit is reached, the solenoid de-energizes, and the lock / unlock cylinder stops. Closing and locking the lid are complete.

[0059] Pressing the unlock button energizes the unlocking solenoid, retracting the locking and unlocking cylinders to unlock the cover. When the unlocking limit is reached, the solenoid de-energizes, stopping the locking and unlocking cylinders. After a delay, the lid opening solenoid energizes, retracting the lid opening and closing cylinders to open the cover. When the lid opening limit is reached, the solenoid de-energizes, stopping the lid opening and closing cylinders. Unlocking and opening the cover are complete.

[0060] The control cabinet panel is equipped with indicator lights for closing, opening, locking and unlocking to show the position status of the cover.

[0061] The pressurization of the high-pressure water tank is completed by the pressure pump motor. Press the pressure start button on the control cabinet panel, then program and run the Yudian AIFCS (2.0) software. The pressure pump motor starts running, filling the water tank with water, and the water tank pressure increases. When the pressure reaches the set pressure, the pressure is stopped and the pressure is maintained. When the program ends, the pressure is automatically released and an alarm is prompted.

[0062] When the selector switch is in automatic mode, the water tank pressure automatically stops when it reaches the value set on the intelligent digital display. When the water pressure returns to the differential value set on the intelligent digital display, the booster pump stops when the pressure reaches the value set on the intelligent digital display. Simultaneously, a timer is run, automatically controlling the water tank pressure and time according to a multi-segment program programmed in the intelligent instrument. When the pressure test is complete, the valve release button on the control cabinet panel must be pressed to release the pressure. The cover can only be unlocked after the pressure reaches zero and the water has been drained. The control cabinet panel features open and closed valve indicators to display the position of the electric ball valve.

[0063] 3. Safety measures:

[0064] 1) The water system is equipped with a water pressure switch with a setting value of 5.25MPa. It is forbidden to open the cover when the water is under pressure or full of water.

[0065] 2) The electronic control system is equipped with an emergency stop button. When an abnormal working condition occurs, the emergency stop button can be pressed to cut off the power supply of the equipment. The high-pressure water tank casing is grounded to prevent leakage.

[0066] 3) In addition to electrical protection, the high-pressure water tank pressure protection also uses a spring-loaded safety valve on the pipeline for overpressure protection, and the operating pressure is set to 5.5Mpa.

[0067] 4) The intelligent instrument AI-719P is equipped with an upper limit alarm protection, and the set value is 5.12MPa.

[0068] 5) When the pressure relay is activated, the frequency converter alarms, or the measured value of the intelligent instrument exceeds the upper limit, the warning light will sound and light alarm.
