[0001] The utility model provides a patrol lock, which belongs to the technical field of transformer substation protection, and particularly relates to an intelligent patrol lock for transformer substation. Background Art

[0002] A substation is a facility in a power system that converts electrical energy from a high-voltage transmission system into low-voltage electrical energy suitable for industrial, commercial and household use. It usually includes transformers, switchgear, protection devices and control systems, and its main functions are voltage conversion, power distribution and power system protection. Inspection locks are safety tools used for inspection and maintenance of power equipment. They lock the equipment or operation interface to ensure that the equipment is in a safe state during equipment inspection or maintenance, preventing unauthorized personnel from operating the equipment by mistake or restarting the equipment before maintenance is completed, thereby ensuring the safety of staff and the normal operation of equipment.

[0003] After the existing inspection lock is turned on and the protective door is opened, if the electronic key is taken out of the electronic lock, the electronic key may slip out of the electronic lock when the operator checks the internal situation, which may easily cause the electronic key to fall and be damaged. If the electronic key is taken out in advance, it is necessary to reinsert the electronic key to lock the door when closing the safety door. The operation is too cumbersome and reduces maintenance efficiency. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] like Figure 1 , 2 As shown in Figure 3, the intelligent inspection lock for a substation includes an intelligent electronic key 1 and an intelligent electronic lock 2 corresponding to the intelligent electronic key 1, characterized in that: a symmetrically distributed T-shaped limit rod 11 is movably connected to one end of the intelligent electronic key 1 close to the intelligent electronic lock 2, a lock core 21 corresponding to the limit rod 11 is connected between the limit rods 11 through a lock head 12, arc-shaped limit grooves 22 arranged in the intelligent electronic lock 2 and symmetrically distributed are arranged on both sides of the lock core 21, the limit grooves 22 correspond to the limit rods 11, and blocking surfaces 23 arranged on both sides of the limit groove 22 and corresponding to the limit rods 11 are arranged above the lock core 21, and the blocking surfaces 23 and the bottom surface of the limit groove 22 are on the same horizontal plane.

[0029] In this embodiment, by setting up a smart electronic key 1 and a smart electronic lock 2 corresponding to each other, the smart electronic key 1 uses a symmetrically distributed T-shaped limit rod 11. After the unlocking rotation, the limit rod 11 enters the limit groove 22. With the corresponding shape of the limit groove 22 and the limit rod 11, the smart electronic key 1 always maintains a firm connection with the smart electronic lock 2 in the unlocking state, thereby preventing itself from slipping. At the same time, when locking, you only need to twist the smart electronic key 1; during the insertion process, the limit rod 11 first contacts the blocking surface 23, and the blocking surface 23 squeezes the limit rod 11 into the back of the smart electronic key 1, thereby ensuring that the limit rod 11 smoothly enters the limit groove 22.

[0030] like Figure 4 and Figure 5 As shown, a fingerprint identifier 13 is provided on one side of the smart electronic key 1, and the fingerprint identifier 13 is electrically connected to the control center 3 through the network. A sliding groove 14 is provided on one end of the limit rod 11 close to the inside of the smart electronic key 1, and a limit ring 15 corresponding to the slide groove 14 is sleeved on the outside of the limit rod 11. A spring 16 disposed inside the smart electronic key 1 is provided below the limit rod 11. A connecting groove 17 corresponding to the limit rod 11 and the limit ring 15 is provided on the smart electronic key 1. A contact sensor 18 corresponding to each other is provided inside the connecting groove 17 and on one end of the limit rod 11 close to the spring 16. The contact sensor 18 is electrically connected to the fingerprint identifier 13. An identity recognition module 31 corresponding to the fingerprint identifier 13, a timer 32 corresponding to the contact sensor 18, and an alarm module 33 electrically connected to the timer 32 are provided in the control center 3. The alarm module 33 is connected to a signal receiving device disposed inside the smart electronic key 1 through a signal sending device 34, and the signal receiving device is electrically connected to a voice module.

[0031] In this embodiment, when the limit rod 11 is squeezed and the spring is compressed, the corresponding contact sensor 18 is contacted. If the fingerprint verification is passed, the timer 32 will start timing from the moment of contact, record the current working time and save it to the local storage, and set the time threshold according to the previous average working time. After exceeding the threshold, the timer 32 will start the alarm module 33, thereby starting the voice module to remind the operator to prevent the operator from forgetting to take away the smart electronic key 1 and forgetting to lock the door.

[0032] When using:

[0033] 1. Preparation stage:

[0034] Ensure that the power supply of smart electronic key 1 and smart electronic lock 2 is sufficient and the system is in normal working condition.

[0035] 2. Identity verification:

[0036] The operator aligns the fingerprint identifier 13 on one side of the smart electronic key 1 with his or her finger for fingerprint recognition.

[0037] The fingerprint identifier 13 is electrically connected to the control center 3 via the network to verify the identity of the operator.

[0038] 3. Key insertion:

[0039] The operator aligns one end of the smart electronic key 1 with the smart electronic lock 2 and inserts the limiting rod 11 into the limiting groove 22 of the lock.

[0040] During the insertion process, the limiting rod 11 will first contact the blocking surface 23 , and the blocking surface 23 will squeeze the limiting rod 11 into the back of the smart electronic key 1 , ensuring that the limiting rod 11 smoothly enters the limiting groove 22 .

[0041] 4. Unlocking operation:

[0042] After the fingerprint recognition is passed, the operator turns the smart electronic key 1 to unlock the door.

[0043] The limiting rod 11 enters the limiting groove 22 after being rotated to unlock, and the smart electronic key 1 and the smart electronic lock 2 are firmly connected to prevent slipping.

[0044] 5. Inspection work:

[0045] After unlocking, operators can safely conduct inspections of the substation.

[0046] 6. Timing and alarm:

[0047] Once the limiting rod 11 is pressed in, the contact sensor 18 contacts and triggers the timer 32 to start timing.

[0048] The timer 32 records the working time of this time, and according to the preset time threshold, if the threshold is exceeded, the alarm module 33 is activated and the operator is reminded through the voice module.

[0049] 7. End of work:

[0050] After the operation is completed, the operator needs to manually turn the smart electronic key 1 to lock the door.

[0051] After locking, the smart electronic lock 2 will be locked again to ensure the safety of the substation.

[0052] 8. Retrieve the key:

[0053] The operator should ensure to retrieve the smart electronic key 1 before leaving to avoid forgetting it.

[0054] 9. System reset:

[0055] Before leaving the site, the operator should ensure that the system is reset and all related functions are turned off in preparation for next use.

[0056] Through the above steps, the intelligent inspection lock system not only improves the security of substation inspection, but also enhances the operational standardization and safety of operators through fingerprint recognition and timing alarm functions.
