[0002] In the existing thrust external circulation control loop, PLC (programmable logic controller) is usually used for control. However, the conventional control loop has some problems, such as single relay control of the control loop, which leads to insufficient stability of the system and easily causes equipment failure. In addition, the PLC failure is not fully considered and processed in the conventional control loop, so that the oil pump cannot normally operate when the PLC fails, which seriously affects the stability and safety of the unit. Meanwhile, it is difficult to quickly clamp and fix the line after adjustment of the control loop, which leads to the phenomenon of short circuit caused by mutual entanglement of the line after the line is changed, thereby affecting the use of the equipment. Therefore, it is necessary to optimize and improve the thrust external circulation control loop to improve the stability and reliability of the system, eliminate major equipment hazards of the unit, and ensure safe and stable operation of the unit.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1

[0044] This is the first embodiment of the present invention, which provides a method for optimizing the external circulation control loop of a generator thrust, including:

[0045] S1: Optimize and improve the thrust external circulation control system loop: Modify the single relay control for starting and stopping the oil pump in the PLC to dual relay control for starting and stopping the oil pump;

[0046] S2: Modify the normally closed contact of the oil pump stop: Modify the normally open contact of the pump start relay output by the PLC in the start-stop circuit to the normally closed contact of the oil pump stop and the automatic position contact of the control handle in series. After modification, the circuit is re-clamped and fixed by the wire fixing mechanism.

[0047] S3: Improve the thrust external circulation control program: Add a pump stop relay to the PLC program to control pump start and stop separately, and then conduct tests;

[0048] S4: Testing and Verification: In automatic control mode, with any oil pump running, power off the PLC to simulate a PLC fault, and run the oil pump to maintain the running state before the fault.

[0049] Specifically, testing and verification steps can be carried out using automated testing equipment or manual testing.

[0050] Operation process: Optimize and improve the thrust external circulation control system loop: Modify the single relay control for starting and stopping the oil pump in the PLC to dual relay control for starting and stopping the oil pump; modify the normally open contact of the PLC start relay in the start-stop loop to the normally closed contact of the oil pump stop relay and the automatic position contact of the control handle in series; improve the thrust external circulation control program: add a stop relay to the PLC program, separate the start and stop control of the pump; test and verify that under the automatic control mode, with any oil pump running, the PLC is powered off to simulate a PLC fault, and the running oil pump maintains the running state before the fault.

[0051] The aim is to improve the operational reliability of the thrust external circulation system, eliminate major equipment hazards, and ensure the safe and stable operation of the unit.

The normally open contact of the pump start relay in the oil pump start-stop control circuit is changed to a normally closed contact for pump stop, and the automatic position contact of the control handle is connected in series. Even after a PLC failure in the thrust external circulation control system, the thrust external circulation oil pump can still operate normally.

[0052] Example 2

[0053] Reference Figures 1-6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fixed-line device, which includes the above-mentioned method for optimizing the external circulation control loop of the unit thrust, and also includes a structural component 100, which includes an AC contactor body 101 and a mounting component 102 disposed on one side of the AC contactor body 101.

[0054] The clamping assembly 200 includes a clamping member 201 disposed on one side of the mounting member 102, an adjusting member 202 disposed on one side of the mounting member 102, a limiting member 203 disposed on one side of the clamping member 201, and a resetting member 204 disposed on one side of the mounting member 102. The clamping member 201 is used to clamp and secure the cable, the adjusting member 202 is used to drive and adjust whether the clamping member 201 is clamped or not, the limiting member 203 is used to limit the clamping member 201 when adjusting it, and the resetting member 204 is used to reset the clamping member 201.

[0055] The clamping assembly 300 includes a movable member 301 disposed on one side of the mounting member 102 and a clamping member 302 disposed on one side of the movable member 301. The movable member 301 is used to drive the movable member 301 to move when the clamping member 201 is activated to clamp the cable, thereby driving the clamping member 302 to perform auxiliary clamping on the cable. The clamping and clamping work together to improve the cable fixing effect of the device.

[0056] The clamping member 201 includes a mounting frame 201a disposed on one side of the mounting member 102 and a pressure plate 201c slidably disposed within the mounting frame 201a. The adjusting member 202 includes a rotating rod 202b rotatably disposed on one side of the mounting member 102, a shaped protrusion 202e disposed on the outside of the rotating rod 202b, and a toggle rod 202d. The shaped protrusion 202e contacts the pressure plate 201c.

[0057] Specifically, the mounting component 102 includes a base plate 102a disposed on one side of the AC contactor body 101 and connecting plates 102b disposed on both sides of the base plate 102a. The clamping component 201 includes a mounting frame 201a disposed on one side of the base plate 102a, a placement plate 201b disposed inside the mounting frame 201a, and a wire clamping plate 201c slidably disposed on one side of the placement plate 201b. The wire clamping plate 201c can slide and rotate slightly within the placement plate 201b to clamp the contactor body. The cable below the pressure plate 201c is pressed and fixed. The pressure member 201 also includes a buffer spring 201e set inside the mounting frame 201a and a pressure block 201d set on one side of the pressure plate 201c. The buffer spring 201e is used to buffer and reset the placement plate 201b after it is squeezed when the pressure plate 201c rotates. The pressure block 201d is set in an arc shape and can be used to improve the pressure plate 201c's effect on the cable.

[0058] Furthermore, the adjusting component 202 includes a fixed plate 202a disposed on one side of the base plate 102a, a rotating rod 202b rotatably disposed on one side of the fixed plate 202a, and a turntable 202c disposed on one side of the rotating rod 202b. The adjusting component 202 also includes a toggle rod 202d sleeved on the outside of the rotating rod 202b, a shaped protrusion 202e disposed on the outside of the rotating rod 202b, and an adjusting groove 202f opened on one side of the pressure plate 201c. The adjusting groove 202f is configured as an upper rectangular straight groove and a lower wedge-shaped groove, and the cross-sectional area of ​​the lower wedge-shaped groove is larger than the cross-sectional area of ​​the upper rectangular straight groove. The toggle rod 202d can extend into the adjusting groove 202f. When the rotating rod 202b rotates, it can drive the toggle rod 202d and the turntable 202c. When the irregular protrusion 202e rotates, in the initial state, the actuating rod 202d extends into the adjusting groove 202f and contacts the rectangular straight groove. At this time, the irregular protrusion 202e separates from the pressing plate. When the rotating rod 202b rotates, the adjusting rod first contacts the inner wall of the left side of the rectangular straight groove, slightly actuates the pressure plate 201c, and then the adjusting rod contacts the inclined surface of the wedge groove. During the rotation, the inclined surface of the wedge groove is squeezed, causing the pressure plate 201c to rotate slightly, thereby pressing and fixing the cable. At the same time, during the rotation of the rotating rod 202b, the arc surface of the irregular protrusion 202e rotates until it contacts the pressure plate 201c until it is tightly pressed.

[0059] The limiting member 203 includes limiting grooves 203a formed on both sides of the pressure plate 201c and limiting rods 203b set on both sides of the mounting frame 201a. The limiting rods 203b extend into the limiting grooves 203a. The limiting member 203 also includes an arc-shaped portion 203c set on one side of the limiting groove 203a and a horizontal portion 203d set on one side of the limiting groove 203a. The limiting grooves 203a are used to limit the pressure plate 201c. In the initial state, the limiting rods 203b are located in the arc-shaped portion 203c of the limiting groove 203a. At this time, the pressure plate 201c is in a slightly tilted and relaxed state. When the rotating rod 202b is rotated... When the pressure plate 201c begins to move towards the cable and then rotates slightly to press the cable, the limiting rod 203b begins to slide from the arc-shaped part 203c of the limiting groove 203a towards the horizontal part 203d. The width of the horizontal part 203d of the limiting groove 203a matches the width of the limiting rod 203b. When the limiting rod 203b slides to the horizontal part 203d of the limiting groove 203a, it fixes and limits the pressure plate 201c in the vertical direction. At this time, the irregular protrusion 202e and the pressure plate 201c are pressed tightly against each other, completing the fixation and limiting of the pressure plate 201c, thereby achieving the pressing and securing of the line.

[0060] The rest of the structure is the same as in Example 1.

[0061] Operating Procedure: After adjusting the wiring in the start-stop circuit, when it is time to secure the cable, rotate the lever 202b. The lever first contacts the inner left wall of the rectangular straight groove, slightly moving the pressure plate 201c. Then, the lever contacts the inclined surface of the wedge-shaped groove. During rotation, the inclined surface of the wedge-shaped groove is pressed, causing the pressure plate 201c to rotate slightly, thereby securing the cable. Simultaneously, during the rotation of the lever 202b, the arc-shaped surface of the irregular protrusion 202e rotates due to the separation of the pressure plate 201c until its arc-shaped surface contacts the pressure plate 201c. When the two parts come into contact and press tightly together, the limiting rod 203b begins to slide from the arc-shaped part 203c of the limiting groove 203a toward the horizontal part 203d. The width of the horizontal part 203d of the limiting groove 203a matches the width of the limiting rod 203b. When the limiting rod 203b slides to the horizontal part 203d of the limiting groove 203a, it fixes and limits the pressure plate 201c in the vertical direction. At this time, the irregular protrusion 202e and the pressure plate 201c press tightly together, completing the fixation and limiting of the pressure plate 201c, thereby achieving the clamping and securing of the line.

[0062] Example 3

[0063] Reference Figures 7-8 This is the third embodiment of the present invention. Unlike the previous embodiments, this embodiment provides a cable fixing device, including the method described above for optimizing the external circulation control loop of the generator thrust. The clamping assembly 300 includes a movable member 301 disposed on one side of the mounting member 102 and a clamping member 302 disposed on one side of the movable member 301. The movable member 301 is used to drive the movable member 301 to move when the clamping member 201 is activated to clamp the cable, thereby driving the clamping member 302 to perform auxiliary clamping on the cable. The clamping and clamping work together to improve the cable fixing effect of the device.

[0064] Specifically, the movable component 301 includes a mounting plate 301a disposed on one side of the connecting plate 102b, a slide rod 301b disposed on one side of the mounting plate 301a, and a first clamping plate 301c slidably disposed on the outside of the slide rod 301b. The movable component 301 also includes a wedge block 301d disposed on one side of the first clamping plate 301c, a connecting rod 301e disposed on one side of the pressure plate 201c, and a compression ball 301f disposed on one side of the connecting rod 301e. In the initial state, the compression ball 301f and the wedge block 301d are separated from each other. f contacts the wedge 301d. The moving part 301 also includes a tension spring 301g sleeved on the outside of the slide rod 301b. The two ends of the tension spring 301g are connected to the first clamping plate 301c and the mounting plate 301a respectively, and are used to reset the first clamping plate 301c. When the pressure plate 201c presses and fixes the line, it will drive the connecting rod 301e and the extrusion ball 301f to slide first and then rotate slightly, thereby extruding the wedge 301d and driving the first clamping plate 301c to slide, and perform auxiliary clamping and fixing of the internal line.

[0065] Preferably, the clamping member 302 includes a second clamping plate 302a disposed on the upper side of the connection. The clamping member 302 also includes anti-slip protrusions 302b disposed on the side walls of the first clamping plate 301c and the second clamping plate 302a. The first clamping plate 301c and the second clamping plate 302a cooperate with each other to perform auxiliary clamping and fixing of the internal circuit. The anti-slip blocks can improve the clamping effect of the clamping plates.

[0066] Furthermore, the reset component 204 includes a vertical plate 204a disposed on one side of the base plate 102a and a reset spring 204b disposed on one side of the vertical plate 204a. The two ends of the reset spring 204b are respectively connected to the side wall of the vertical plate 204a and the side wall of the pressure plate 201c. The reset spring 204b slides and resets together with the auxiliary pressure plate 201c.

[0067] The rest of the structure is the same as in Example 2.

[0068] Operation process: When the pressure plate 201c presses and fixes the wire, it will drive the connecting rod 301e and the compression ball 301f to move towards the wedge block 301d, so that the compression ball 301f and the wedge block 301d move from a separated state to a close contact until the wedge block 301d is pressed. This will drive the first clamping plate 301c to slide in the direction where the wire is placed. While completing the pressing, the wire is clamped and fixed. The two work together to improve the wire fixing effect of the device.

[0069] When the line needs to be readjusted, the rotating rod 202b is rotated in the reverse direction. At this time, the irregular protrusion 202e separates from the pressure plate 201c, and the adjusting rod re-enters the rectangular straight groove of the adjusting groove 202f, causing the pressure plate 201c to move in the reverse direction, thereby removing the pressure plate 201c from the line and releasing the clamping force on the line. At this time, the limiting rod 203b begins to slide from the horizontal part 203d of the limiting groove 203a towards the arc-shaped part 203c. When it slides to the arc-shaped part 203c, it causes the pressure plate 201c to begin to rotate and tilt slightly, making contact with the line. The circuit is clamped and fixed, and the reset spring 204b assists in the reset sliding of the pressure plate 201c. At the same time, when the pressure plate 201c is moved away in the opposite direction, the compression ball 301f is driven to separate from the wedge block 301d, releasing the compression of the wedge block 301d. At this time, the first clamping plate 301c is driven to separate from the second clamping plate 302a by the rebound force of the tension spring 301g, releasing the clamping and fixing of the circuit, and readjusting the circuit in the start-stop circuit.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
