[0042] Please refer to the attached Figure 12 -attached Figure 14 A method for using a mechanical lock, for a mechanical lock, the socket 2 and the plug 3 locking comprises the following steps:
[0043] Step one: confirming that the feeder cabinet is in the state of the circuit breaker being tripped and the grounding knife being closed, the socket 2 is normally connected with each component of the mechanical lock 1 and is firmly installed, and the mechanical lock 1 is in the initial state;
[0044] Step two: accurately inserting the plug 3 into the socket 2 to realize electrical connection between them;
[0045] Accurately inserting the plug 3 to establish electrical connection is the starting step of shore power transmission, ensures that the plug 3 is tightly matched with the socket 2, guarantees stable power transmission, avoids problems such as arc and heating due to poor contact, and influences the normal operation of the electrical equipment and causes safety hazards;
[0046] Step three: inserting the locking key 105 into the inside of the mechanical lock cylinder 103, at this time, the locking key 105 is matched with the mechanical lock cylinder 103, taking the mechanical washer 102 as a support point, rotating the locking key 105 clockwise or counterclockwise, with the rotation of the locking key 105, the mechanical lock cylinder 103 is driven to rotate, and since the mechanical lock cylinder 103 is fixedly connected with the paddle 106 at the bottom, the paddle 106 will move with the rotation of the mechanical lock cylinder 103;
[0047] Insert and rotate the locking key 105, and use the cooperation between the mechanical lock core 103 and the locking key 105 and the support of the mechanical washer 102 to realize power transmission. Rotate the locking key 105 to drive the mechanical lock core 103 to rotate, and then drive the toggle piece 106 to prepare for pushing the mechanical lock bolt 104. Through this mechanical structure transmission, the locking operation of the plug 3 is realized.
[0048] Step four: in the process of rotating the toggle piece 106, the sliding connection structure between the toggle piece 106 and the mechanical lock bolt 104 makes the toggle piece 106 push the mechanical lock bolt 104, and the mechanical lock bolt 104 slides in the inner diameter of the mechanical lock seat 101 and gradually extends out of the mechanical lock seat 101. When the mechanical lock bolt 104 extends to a certain position, it will cooperate with the corresponding locking structure on the plug 3 to clamp the plug 3.
[0049] The sliding connection structure between the toggle piece 106 and the mechanical lock bolt 104 converts the circular motion of the toggle piece 106 into the linear motion of the mechanical lock bolt 104. After the mechanical lock bolt 104 extends out, it cooperates with the locking structure on the plug 3 to clamp the plug 3, preventing the plug 3 from being accidentally pulled out, ensuring that the plug 3 is firmly connected to the socket 2, and avoiding safety accidents caused by the loosening of the plug 3 during power transmission.
[0050] Step five: after confirming that the mechanical lock bolt 104 has firmly clamped the plug 3 and the plug 3 is restricted in the socket 2 and cannot be easily pulled out, pull out the locking key 105 from the mechanical lock core 103. At this time, the plug 3 has been locked in the socket 2. Insert the locking key 105 into the key exchange box, then take out the second locking key 105, operate the second mechanical lock 1 installed at the high-open cabinet ground knife with the second locking key 105, and retract the lock pin. At this time, the ground knife can be operated to open, and the second locking key 105 cannot be pulled out. Then, open the ground knife, close the circuit breaker, and then wait for the power supply to be completed to unlock and separate the socket 2 and the plug 3.
[0051] After confirming that the plug 3 is firmly locked, pull out the key to increase the safety of the operation and prevent misoperation from unlocking. Insert the key into the key exchange box to obtain the second key, which is used for subsequent operation of the mechanical lock 1 at the high-open cabinet ground knife. Operate the mechanical lock 1 to retract the lock pin, and then open the ground knife to prepare for closing the circuit breaker. This process realizes shore power supply under safe conditions through key exchange and multi-device interlocking operation, avoiding the danger of live operation.
[0052] The unlocking and separation of the socket 2 and the plug 3 includes the following steps:
[0053] Step one: use the second locking key 105 to operate the second mechanical lock 1 installed at the high-open cabinet ground knife. The lock pin extends out, the circuit breaker is reopened, the ground knife is closed, and it is confirmed that the surrounding environment is safe and there is no electrical safety hazard.
[0054] Step two: the second lock key 105 is reinserted into the key exchange box, and then the lock key 105 is taken out and reinserted into the mechanical lock core 103 inside the socket 2, so that the lock key 105 and the mechanical lock core 103 are matched again;
[0055] The second key is put back into the exchange box, and the original lock key is taken out, in order to follow the interlocking logic flow, reinsert the lock key into the mechanical lock core 103, prepare for unlocking the plug 3, ensure that the unlocking operation is in the predetermined order, and ensure the accuracy and safety of the operation;
[0056] Step three: rotate the lock key 105 in the opposite direction of locking, drive the mechanical lock core 103 to rotate, and then drive the bottom of the actuator 106 to rotate;
[0057] Reverse rotation of the lock key 105 drives the mechanical lock core 103 and the actuator 106 to rotate in the opposite direction through mechanical structure transmission, providing power to pull back the mechanical lock tongue 104, and realizing the first step of unlocking the plug 3 according to the opposite mechanical action principle of locking;
[0058] Step four: during the rotation of the actuator 106, the mechanical lock tongue 104 is pulled through the sliding connection structure between the actuator 106 and the mechanical lock tongue 104, so that it slides back in the mechanical lock seat 101, and gradually retreats into the mechanical lock seat 101;
[0059] The sliding connection between the actuator 106 and the mechanical lock tongue 104 converts the reverse rotation of the actuator 106 into the reverse linear motion of the mechanical lock tongue 104, so that the mechanical lock tongue 104 retreats and releases the locking of the plug 3, creating conditions for pulling out the plug 3;
[0060] Step five: when the mechanical lock tongue 104 completely retreats and no longer blocks the plug 3, hold the plug 3 and pull it out smoothly from the top of the socket 2, complete the unlocking and pulling out of the plug 3.
[0061] After confirming that the mechanical lock tongue 104 has completely retreated, pull out the plug 3, ensure that the plug 3 is unlocked in place, avoid forcibly pulling out and damaging the equipment, pull out the plug 3 smoothly, ensure the safety of the operation, complete the entire unlocking process, and make the equipment unlock to the initial separable state.
[0062] Please refer to the attached Figure 15 -attached Figure 17 A method for using a mechanical safety logic interlock, for a mechanical safety logic interlock, comprising the following steps:
[0063] Step one: the logic first key 9 is inserted into the corresponding logic lock core 13 from bottom to top, and the logic second key 10 is inserted into the top of the logic lock core 13.
[0064] The corresponding relationship between the keys and the lock core is clear, and the logic first key 9 is inserted in order, which is the starting operation of the logic interlocking. Through this ordered insertion method, the logic interlocking mechanism is started, and only in a specific key operation sequence, the subsequent key operation can be performed, thereby improving the operation safety and logic.
[0065] Step two: after the selected key is inserted into the corresponding logic lock core 13, the key is rotated clockwise or counterclockwise, and the rotation of the logic first key drives the rotation of the logic lock core 13 and the logic first paddle 6.
[0066] The rotation of the logic first key 9 drives the rotation of the logic lock core 13 and the logic first paddle 6, realizing mechanical power transmission. Through the cooperation of the logic first key 9 and the logic lock core 13, and the fixed connection relationship between the logic lock core 13 and the logic first paddle 6, the rotation power is transmitted in sequence, providing power support for the subsequent action of the logic lock tongue 5 and the unlocking of the logic second key 10.
[0067] Step three: with the rotation of the logic first paddle 6, since the logic first paddle 6 and the logic lock tongue 5 are in a sliding connection relationship, the paddle rotates and pushes the logic lock tongue 5 to slide in the logic pin slot 11, so that the originally locked logic second key 10 is unlocked, and then the logic second key 10 is rotated, driving the rotation of the top logic lock core 13 and the rear-end logic second paddle 12.
[0068] The logic first paddle 6 pushes the logic lock tongue 5 to slide, changes the position of the logic lock tongue 5, and thus unlocks the logic second key 10. The rotation of the logic second key 10 drives the rotation of the top logic lock core 13 and the logic second paddle 12. Through the sliding connection between the logic first paddle 6 and the logic lock tongue 5, and the cooperation between the logic second key 10 and the top logic lock core 13 and the logic second paddle 12, the key unlocking step of the logic interlocking is realized, and the operation is ensured to be performed in a specific logic sequence.
[0069] Step four: the logic second key 10 K5 can be pulled out from the top logic lock core 13, the logic first key 9 K1-K4 is locked in the exchange box, the key K5 is used to operate the mechanical lock installed at the ground knife of the feeder cabinet AJ1, the lock pin is retracted, and the key K6 is withdrawn. At this time, the ground knife is operated to be opened, and K5 cannot be pulled out.
[0070] Pull out the second logic key 10K5, and at the same time lock the first logic key 9K1-K4 to realize key exchange and operation restriction. Use the pulled-out key K5 to operate the mechanical lock at the grounding switch AJ1 of the feeder cabinet, retract the locking pin and open the grounding switch. Through the coordinated work of the various components of the logic interlock, the standardization and safety of the operation process are ensured, and electrical accidents caused by misoperation are avoided.
[0071] Step 5: Use key K6 to operate the mechanical lock installed at the grounding switch of feeder cabinet AJ2. The locking pin will retract. Remove key K7. At this time, operate the grounding switch to trip, and K6 cannot be pulled out. According to the ship's power supply system, select 11kV feeder cabinet AJ1 or 6.6kV feeder cabinet AJ2. Use key K7 to operate the mechanical lock installed at the circuit breaker trolley of one of the cabinets. The locking pin will retract, and the circuit breaker trolley can be pushed to the working position. K7 cannot be pulled out. After the status is confirmed to be in place, close the circuit breaker and the shore power supply will supply power to the ship.
[0072] Continue to use the key to operate the relevant mechanical locks of the feeder cabinet in sequence, and gradually advance the power supply preparation work. Select the appropriate feeder cabinet according to the ship's power supply system, operate the mechanical lock at the circuit breaker truck to put the circuit breaker truck in place, and close the circuit breaker to realize power supply after confirming the status. The entire process ensures the safe and accurate operation of shore power supply through multi-level interlocking and condition judgment. Based on the logic interlocking principle, it ensures that each step of the operation complies with safety regulations.
[0073] Step Six: When power supply to the ship is stopped and the interlock is unlocked, the first key 9K1-K4 of the unlocking logic is achieved by reversing the displacement path of the logic lock tongue.
[0074] Unlocking the first key, 9K1-K4, involves the following steps:
[0075] Step 1: After completing the power supply operation, return the circuit breaker truck to the test position and open the circuit breaker. Turn the key K7 counterclockwise to reset it. After the locking pin pops out, pull out K7. Close the grounding switch. Turn the key K6 counterclockwise to reset it. After the locking pin pops out, pull out K6. Insert the top logic second key K5 into the corresponding lock cylinder. Rotate it counterclockwise to drive the logic second lever 12 to rotate in the opposite direction, so that the logic lock tongue 5 slides back to the initial position along the pin groove 11.
[0076] After power supply is completed, a series of reset operations are performed: the circuit breaker truck is returned and the circuit breaker is opened, the grounding switch is restored to the closed state, the key is turned to reset the lock and pull it out, and then the second logic key K5 is inserted and rotated in the reverse direction, which drives the second logic lever 12 to return the logic lock tongue 5 to the position, in preparation for unlocking the first logic key 9K1-K4. Ensure that the operation unlocks the initial interlocking state of the equipment in sequence, and unlock the equipment state step by step according to the reverse operation principle of logic interlocking.
[0077] Step two: rotate the logic first key K4, K3, K2, K1 in reverse order counterclockwise, reset each logic first paddle 6, and remove the pushing force on the logic bolt 5;
[0078] Reverse rotation of the logic first key 9K4, K3, K2, K1 resets the logic first paddle 6, removes the pushing force on the logic bolt 5, and gradually unlocks the logic interlocking part position, following the reverse of the normal operation logic, creating conditions for unlocking the logic first key 9K1-K4, through the cooperation of the logic first key 9 and the logic lock cylinder 13, driving the logic first paddle 6 to rotate in reverse, thereby removing the effect on the logic bolt 5, and returning the logic interlocking part to the initial state;
[0079] Step three: when all the logic bolts 5 are reset to the locked state, the logic first key 9K1-K4 is automatically unlocked and can be pulled out one by one from the exchange box, completing the interlocking state unlocking.
[0080] The logic bolt 5 is reset to the locked state, triggering the logic first key 9K1-K4 to unlock, which can be pulled out from the exchange box, completing the entire interlocking state unlocking.
[0081] The key rotation angle is controlled by a mechanical limiting structure, the inner wall of the logic lock cylinder 13 is provided with a 90° limiting boss, and the handle of the logic first key 9 is provided with a guide sliding groove matched with the limiting boss.
