Description

Technical Field

[0001] The invention relates to the technical field of maintenance of hydraulic hoist for ship lock in hydropower station, and in particular to a simulation system of hydraulic hoist for ship lock and an operation method thereof. Background Art

[0002] The reverse arc gate of the working valve of the ship lock water delivery system is mostly controlled by a hydraulic hoist to achieve the purpose of filling and draining the lock chamber. The hydraulic hoist is composed of power components, actuators, control components and auxiliary components: the power components include axial piston pumps, etc.; the actuators include hydraulic cylinders, etc.; the control components include various control valves (directional control valves, pressure control valves, flow control valves and electro-hydraulic proportional valves, etc.) or a combination of various valves. Among them, the pump station is the power of the hoist, and the hydraulic valves, such as relief valves, pilot relief valves, solenoid reversing valves, three-position four-way electro-hydraulic reversing valves, balancing valves, plate-type stop valves, etc., are arranged on the oil tank in an integrated form. Different combinations of these components constitute a hydraulic system that can perform different functions.

[0003] On the one hand, because the hydraulic system has a wide variety of components and is complex, it requires that the ship lock operators and maintenance personnel must master relevant hydraulic expertise. The hydraulic system of the ship lock hydraulic hoist is in operation all year round, and the ship lock operators and maintenance personnel have few opportunities to disassemble the hydraulic components in the hydraulic system, and it is difficult to access the internal structure and working principle of the main hydraulic components. The direction of the oil in the hydraulic circuit and the position and movement process of the hydraulic components in the system are not clear enough, which makes it impossible for technicians to efficiently troubleshoot sudden hydraulic failures, causing a certain degree of safety hazards and affecting the efficiency of ship passing through the lock; on the other hand, due to the complex structure of the hydraulic system, the process flow is relatively abstract in the training materials, and the structure and working principle of the hydraulic components and system circuits are described in words and some simple graphic symbols, which is difficult to achieve ideal results in the training of new employees.

[0004] In order to solve the above problems, it is urgent to develop an interactive hydraulic simulation system for the hydraulic system of the gate hoist, so as to meet the technical gaps in the inspection, maintenance and training of the lock hydraulic system and ensure the safe and efficient operation and maintenance of the lock. Summary of the invention

[0005] In order to solve the current technical problems, the main purpose of the present invention is to provide a ship lock hydraulic hoist simulation system and an operation method thereof to meet the needs of the ship lock hydraulic hoist hydraulic system in terms of overhaul, maintenance and training.

[0006] The technical solution adopted by the present invention is: a ship lock hydraulic hoist simulation system, comprising: A first module, wherein the first module includes mechanical component, hydraulic component and electrical component models for dynamically simulating a ship lock hydraulic hoist system, wherein each model is virtually connected to pipelines and circuits through the same structure as the ship lock hydraulic hoist system; a second module, the second module being used to dynamically display the flow direction of the hydraulic oil in the first module; The third module is used to switch different working modes and control the first module and the second module to dynamically display according to the preset working mode to show the operating logic of the ship lock hydraulic hoist system and the flow pattern of the hydraulic oil.

[0007] The working modes include valve opening mode, valve closing mode, valve collapse mode, emergency valve closing mode and fault diagnosis mode. By entering different modes, simulation demonstration and reasoning of the corresponding hydraulic process are performed to simulate different operating scenarios and fault conditions.

[0008] It also includes a fourth module, which is used to enlarge and accurately display the mechanical component or hydraulic component through a three-dimensional model and / or an exploded view after clicking the corresponding mechanical component or hydraulic component.

[0009] It also includes a fifth module, which is used to voice broadcast and explain the flow direction of hydraulic oil and the actions of hydraulic components and mechanical components under different working modes.

[0010] A ship lock hydraulic hoist simulation operation method adopts the ship lock hydraulic hoist simulation system for simulation demonstration and operation of the ship lock hydraulic hoist system. The operation method includes: valve opening working steps, valve closing working steps, valve collapse working steps, emergency valve closing steps and fault diagnosis steps. According to a preset program, the simulation demonstration and reasoning process of the ship lock hydraulic hoist system is started for different working modes.

[0011] The valve opening working steps include: After receiving the command and entering the valve opening mode, DT1 on the three-position four-way solenoid directional valve in the first module is energized, and the first motor starts to drive the oil pump to run at no load for a few seconds, after which DT1 is powered off and enters the valve opening procedure. At this time, DT4 on the three-position four-way electro-hydraulic directional valve is energized, and the pressure oil flows through the one-way valve, the three-position four-way electro-hydraulic reversing valve and the balancing valve, and enters the lower chamber of the cylinder, pushing the piston upward to complete the valve opening process. At the same time, the oil in the upper chamber flows back to the oil tank through the three-position four-way electro-hydraulic reversing valve.

[0012] The valve closing working steps include: After receiving the command and entering the valve closing mode, DT1 on the three-position four-way solenoid reversing valve in the first module is energized, and the second motor starts to drive the oil pump to run at no load for a few seconds, then DT1 is powered off and enters the valve closing program. At this time, DT2 on the three-position four-way solenoid reversing valve and DT3 on the three-position four-way electro-hydraulic reversing valve are energized, and the pressure oil flows through the one-way valve and the three-position four-way electro-hydraulic reversing valve, and enters the upper chamber of the cylinder, pushing the piston downward and at the same time pushing the valve core of the balancing valve to move to the right, and the oil in the lower chamber of the cylinder flows back to the oil tank through the throttle hole of the balancing valve and the three-position four-way electro-hydraulic reversing valve.

[0013] The valve collapse working steps include: After receiving the command and entering the valve collapse mode, the connecting valve in the first module opens, directly connecting the upper and lower chambers of the oil cylinder, and the anti-arc door falls and closes under the action of its own weight.

[0014] The emergency valve closing step includes: When the valve opening step is in progress and emergency valve closing is required, the command is received and the emergency valve closing mode is entered. DT4 on the three-position four-way electro-hydraulic reversing valve in the first module loses power, and DT1 on the three-position four-way solenoid reversing valve is energized. After the first motor drives the oil pump to run at no load for a few seconds, DT1 and the first motor are simultaneously de-energized and the valve closing start-up procedure is performed. DT1 on the three-position four-way solenoid reversing valve is energized, and the second motor starts to drive the oil pump to run at no load for a few seconds. After that, DT1 is de-energized and the valve closing procedure is performed. DT2 on the three-position four-way solenoid reversing valve and DT3 on the three-position four-way electro-hydraulic reversing valve are energized, and the pressure oil flows through the one-way valve and the three-position four-way electro-hydraulic reversing valve into the upper chamber of the oil cylinder, pushing the piston downward and at the same time pushing the valve core of the balancing valve to move to the right. The oil in the lower chamber of the oil cylinder flows back to the oil tank through the throttle hole of the balancing valve and the three-position four-way electro-hydraulic reversing valve.

[0015] The fault diagnosis steps include: After receiving the command and entering the fault diagnosis mode, the simulation system receives the disconnection or passage setting of the hydraulic components in the first module. At this time, the second module generates a different oil path, the simulation cannot normally switch the valve fault, and an error is reported; The simulation system receives the user's selection and setting of the hydraulic components. If correct, the system returns to normal state. If wrong, it continues to report an error. Among them, when the simulation system receives a fault elimination command, the simulation system skips the fault diagnosis mode and returns to normal state.

[0016] The present invention has the following beneficial effects: The present invention establishes a simulation model of the ship lock hydraulic hoist system through the first module, can display the flow direction of the hydraulic oil in the simulation model through the second module, and can switch different working modes through the third module, so that the actions of the components in the first module and the flow direction of the hydraulic oil in the second module can be understood in different working modes. It satisfies the ship lock hydraulic hoist system to work in application scenarios such as hydraulic system operation and maintenance, troubleshooting, and training. Technicians can understand its internal structure from a dynamic perspective, more intuitively display the working principle of hydraulic components and the actual working process of the oil circuit, deepen employees' understanding of it, and improve the training effect of new employees. It has far-reaching significance for improving the navigation guarantee level of ship locks. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1 , the valve opening working steps include: After receiving the command and entering the valve opening mode, DT1 on the three-position four-way solenoid directional valve in the first module is energized, and the first motor starts to drive the oil pump to run at no load for a few seconds, after which DT1 is powered off and enters the valve opening procedure. At this time, DT4 on the three-position four-way electro-hydraulic directional valve is energized, and the pressure oil flows through the one-way valve, the three-position four-way electro-hydraulic reversing valve and the balancing valve, and enters the lower chamber of the cylinder, pushing the piston upward to complete the valve opening process. At the same time, the oil in the upper chamber flows back to the oil tank through the three-position four-way electro-hydraulic reversing valve.

[0034] See also Figure 2 , the valve closing working steps include: After receiving the command and entering the valve closing mode, DT1 on the three-position four-way solenoid reversing valve in the first module is energized, and the second motor starts to drive the oil pump to run at no load for a few seconds, then DT1 is powered off and enters the valve closing program. At this time, DT2 on the three-position four-way solenoid reversing valve and DT3 on the three-position four-way electro-hydraulic reversing valve are energized, and the pressure oil flows through the one-way valve and the three-position four-way electro-hydraulic reversing valve, and enters the upper chamber of the cylinder, pushing the piston downward and at the same time pushing the valve core of the balancing valve to move to the right, and the oil in the lower chamber of the cylinder flows back to the oil tank through the throttle hole of the balancing valve and the three-position four-way electro-hydraulic reversing valve.

[0035] See also Figure 3 The valve collapse working steps include: After receiving the command and entering the valve collapse mode, the connecting valve in the first module opens, directly connecting the upper and lower chambers of the oil cylinder, and the anti-arc door falls and closes under the action of its own weight.

[0036] See also Figure 4 , the emergency valve closing step includes: When the valve opening step is in progress and emergency valve closing is required, the command is received and the emergency valve closing mode is entered. DT4 on the three-position four-way electro-hydraulic reversing valve in the first module loses power, and DT1 on the three-position four-way solenoid reversing valve is energized. After the first motor drives the oil pump to run at no load for a few seconds, DT1 and the first motor are simultaneously de-energized and the valve closing start-up procedure is performed. DT1 on the three-position four-way solenoid reversing valve is energized, and the second motor starts to drive the oil pump to run at no load for a few seconds. After that, DT1 is de-energized and the valve closing procedure is performed. DT2 on the three-position four-way solenoid reversing valve and DT3 on the three-position four-way electro-hydraulic reversing valve are energized, and the pressure oil flows through the one-way valve and the three-position four-way electro-hydraulic reversing valve into the upper chamber of the oil cylinder, pushing the piston downward and at the same time pushing the valve core of the balancing valve to move to the right.

At this time, the second module generates a different oil path, the simulation cannot normally switch the valve fault, and an error is reported; The simulation system receives the user's selection and setting of the hydraulic components. If correct, the system returns to normal state. If wrong, it continues to report an error. Among them, when the simulation system receives a fault elimination command, the simulation system skips the fault diagnosis mode and returns to normal state.

[0038] Specifically, after the system enters the fault diagnosis mode, the hydraulic component is manually selected on the first module, and it is set to open or close, and then handed over to the technician for operation. At this time, the simulation system produces different oil circuit direction states due to the influence of the selected hydraulic component, which may cause the valve to be unable to switch normally. The system reports an error, and the technician needs to reversely deduce the faulty hydraulic component based on the hydraulic oil circuit in the fault state. If the faulty valve component is correctly selected, the system will return to normal; if the faulty valve component is not selected, the system will continue to report an error; if you need to skip the fault diagnosis system and directly return to normal, click the fault elimination button.
