Meanwhile, when the ring buckle ground wire lock is in a locking state, the mounting screws are hidden, namely the ring buckle ground wire lock adopts a totally enclosed structural design, cannot be disassembled, and has reliable prying resistance, shearing resistance and impact resistance.

As shown in fig. 10, the ground wire token 9 is in a state of opening the buckle ground wire lock, and the ground wire token 9 cannot be taken out in the opened state; when the buckle ground wire lock is unlocked, the first wire clamp part 2 in the buckle ground wire lock can be pulled out from the lock body 1 and separated from the lock body 1, the first ID code piece 2052 of the first wire clamp part 2 can be read by a computer key to indicate that the temporary ground wire is not recovered or in a hanging state, so that a worker is reminded to recover or dismantle the temporary ground wire, and the anti-dismantling leakage is realized.

The following is a temporary grounding wire and an unlocking and locking device, and the specific operation steps during unlocking and locking are as follows:

1) when the temporary grounding wire and the unlocking device are unlocked

As shown in fig. 1 and 10, the ground token 9 is inserted into the lock core 601 and rotated clockwise by 90 °, the locking knob 602 connected to the lock core 601 correspondingly rotates clockwise by 90 °, and the stopper 6021 having the circumference of 1/4 arc protruding from the left end of the locking knob 602 correspondingly rotates 90 °, so that the stopper 6021 is disengaged from the locking groove 2051 in the first clip part 2. At the moment, the buckle ground wire lock is in an unlocking state, and the first wire clamp part 2 can be pulled out of the lock body 1 to be separated from the lock body 1; due to the rotation of the lock knob 602, the self-locking groove 6022 is rotated to a side close to the self-locking pin 6031, the self-locking pin 6031 automatically moves towards the right side of the lock body along the self-locking groove 6022 in the middle of the lock knob 602 under the action of the self-locking pin return spring 6032, and then the flange boss 6035 in the self-locking pin 6031 partially stays in the self-locking groove 6022 in the middle of the lock knob 602, so that the lock knob, the lock cylinder and the ground token 9 cannot perform the reset rotation action, and the automatic locking function (cannot be pulled out) of the ground token 9 is realized.

The handle 902 of the automatically locked ground wire token 9 is rotated by 90 degrees counterclockwise around the unlocking rod 901 and pressed down, so that the handle 902 of the ground wire token 9 is placed in the handle accommodating groove 10 formed at the left end of the lock body 1, the ground wire token 9 cannot be damaged due to impact of external force, and the ground wire can be hung and connected at the moment.

At this time, the latch-type ground wire lock is in an unlocked state, and the first ID code piece can be read by a computer key, so as to determine whether the hanging position of the temporary ground wire 11 corresponds to the temporary ground pile.

2) When the temporary grounding wire and the unlocking device are locked

As shown in fig. 1 and 9, the boss 205 of the first clip portion 2 is inserted into the first receiving groove 4, the right end of the self-locking pin 6031 is forced to move leftward along with the insertion of the boss 205 of the first clip portion 2, and at the same time, the flange boss 6035 of the self-locking pin 6031 enters the annular groove 6023 along the self-locking groove 6022 of the locking knob 602, and at this time, the locking knob, the lock cylinder and the ground token 9 can perform a counterclockwise 90 ° reset rotation action after being separated from the constraint of the self-locking pin 6031.

After the handle 902 of the ground wire token 9 is rotated clockwise by 90 ° around the unlocking lever 901, the ground wire token 9 is rotated counterclockwise by 90 °, so that the limiting block 6021 with 1/4 arc circumference protruding at the right end of the locking knob 602 reenters the locking groove 2051 of the boss 205 on the second clamp portion 2, and the buckle ground wire lock is in a locked state at this time, and the ground wire token 9 is taken out. At this time, the buckle ground wire lock is in a locked state, and the temporary ground wire 11 is in an unavailable state in an end-to-end connection manner.

It should be noted that, based on the above embodiment, the ground wire lock may not be necessarily disposed at both ends of the temporary ground wire, and may be disposed at a relevant position of the temporary ground wire, and it only needs to be ensured that when the ground wire lock is in the locked state, the temporary ground wire is in a state of being folded back and having a length that cannot meet the hooking requirement; when the buckle ground wire lock is in an unlocked state, the temporary ground wire is in a state of freely extending to meet the use requirement, and the corresponding purpose can be achieved. In addition, the identity (i.e. the first ID chip) representing the temporary grounding wire may also be directly set at the hanging end of the temporary grounding wire, instead of being set by the wire clamping portion of the loop-fastening ground wire lock. Namely, various modifications which can only realize the unlocking of the locking device and the hanging state of the temporary grounding wire, can not read the identity of the temporary grounding wire by using a computer key, and can only read the identity of the temporary grounding wire by using the computer key when the temporary grounding wire is in the dismounted state, so as to achieve the aim of preventing the temporary grounding wire from being dismounted are all within the protection scope of the invention.

A control method for preventing misoperation by utilizing the control system for preventing electrical misoperation comprises the following steps in the temporary grounding wire hooking stage:

1) an operator logs in anti-error management software in the five-prevention host, generates an operation order according to operation task simulation and transmits the operation order to a computer key;

2) the token management machine unlocks all ground wire tokens corresponding to the voltage levels according to the operation tasks, an operator takes out the ground wire tokens as required, and the operator carries the ground wire tokens and corresponding temporary ground wires (ring buckle ground wire locks) to go to the site;

3) an operator opens the ring buckle ground wire lock of a group of temporary ground wires by using the ground wire token, and reads a first ID code sheet of the ring buckle ground wire lock in the temporary ground wire to be hung by using a computer key;

4) after confirming that the temporary grounding wire to be hung is matched with the temporary grounding pile, an operator opens a locking lockset on the temporary grounding pile at the hanging point by using a computer key;

5) an operator articulates the temporary grounding wire and restores the temporary grounding pile to be locked after the temporary grounding wire is articulated;

6) after all the operation tasks are completed, the operator returns to the master control room, returns the computer key and returns task information.

And 2) dividing the buckle-in-loop ground wire lock and the ground wire token according to the voltage class, wherein the buckle-in-loop ground wire lock and the ground wire token of the same voltage class are universal.

Step 3), the middle buckle ground wire lock is provided with a first ID code piece with a unique identity mark, and represents the identity of the temporary ground wire; the first ID code chip is positioned in a first wire clamping part of the ground wire lock, and the first wire clamping part is used for fixing a hanging connection end of the temporary ground wire and can be read by a computer key only when the ring buckle ground wire lock is in an open state.

And an operator generates an operation ticket in the five-prevention host according to the operation task simulation. And opening all the ground wire token access authorities in the corresponding voltage classes by the token management machine according to the current operation task, and recording the access conditions. And the operator takes the ground wire token as required according to the task content and carries the ground wire token and the temporary ground wire to the operation site. In the operation process, an operator opens the annular ground wire lock by using the ground wire token, reads a first ID code chip in the annular ground wire lock through a computer key, and binds and corresponds the temporary ground wire and the hanging point (temporary ground pile). Then the operating personnel opens the locking lockset of the grounding pile, articulates the temporary grounding wire, and then restores the locking of the temporary grounding pile to achieve the functions of preventing the temporary grounding from being hung and mistakenly hanging. After all operations are finished, the operator returns to the master control room and returns the computer key operation information. At the moment, the five-prevention host records the ID code of the annular ground wire lock and the information of the hitching point. Each hanging connection point corresponds to a temporary grounding wire.

A control method for preventing misoperation by using the control system for preventing electrical misoperation comprises the following steps in the temporary grounding wire dismantling stage:

2) when an operator arrives at an operation place, taking down the hanging end of the temporary grounding wire;

3) an operator reads a first ID code piece in a first wire clamp part at the hanging end of the temporary grounding wire by using a computer key to confirm the identity of the temporary grounding wire;

4) an operator opens a locking lockset of the temporary grounding point pile by using a computer key, removes the temporary grounding line and restores the temporary grounding pile to be locked after the temporary grounding line is removed;

5) an operator restores the locking of the ring buckle ground wire lock of the temporary ground wire and takes down the ground wire token;

6) after all the operations are finished, returning the temporary grounding wire by the operator;

7) returning the ground wire token to the token management machine by an operator;

8) the operator returns the computer key and returns the task information.

In the temporary grounding wire dismantling operation, the five-prevention host synchronously sends the ID codes of the annular grounding wire locks corresponding to the grounding points to the computer key when an operator simulates operation. Before an operator removes the anti-misoperation lockset of the temporary grounding point, the hanging end of the temporary grounding line must be removed, the first ID code piece of the annular grounding line lock is read through a computer key (if the hanging end of the temporary grounding line is not removed, information in the first ID code piece cannot be read, so that the temporary grounding line can be ensured to be removed), namely the identity of the temporary grounding line is confirmed (whether the removal place is correct or not is confirmed, and the temporary grounding line is prevented from being removed by mistake). Then the operator opens the locking tool of the grounding point, removes the temporary grounding line, locks the annular grounding line lock, and takes out the grounding line token (after removing the grounding line hanging end 12, the grounding end 13 must be removed to realize the locking of the annular grounding line lock, so as to realize the anti-dismantling leakage). After all the operation tasks are finished, the operator needs to return the ground wire token to the token management machine and then return the computer key to the operation information. The five-prevention host can check the number of returned ground line tokens according to the operation task. And when the number of returned ground wire tokens is consistent with the operation task, the current operation task can be ended.

The management of the temporary grounding wire is indirectly realized through the management of the grounding wire token; the structure of the buckle ground wire lock enables a worker to read the identity of the temporary ground wire only by removing the hanging end of the temporary ground wire when the worker removes the ground wire, so that the possibility of illegal operation and the possibility of missing removal are solved, namely the correctness of the whole operation is forcibly ensured by the control method. In addition, after the annular ground wire lock is locked, the ground wire token 9 is taken down to return the management position to realize scientific management.

One end of the self-locking sleeve return spring 6025a is fixed on the return torsion spring snap plate 6023 a.

As shown in fig. 13, 15, 20, and 21, the locking mechanism 603a includes a self-locking sleeve 6031a, a locking hook 6032a, and a locking hook return spring 6033 a. The self-locking sleeve 6031a is sleeved outside the self-locking sleeve return spring 6025a nested on the lock knob 602a, and one end of the self-locking sleeve return spring 6025a is fixed on the inner wall of the self-locking sleeve 6031 a. An interlocking hook accommodating groove 6026a is axially formed in the right end of the lock knob 602a from the end surface, and a pin hole 6024a is formed in the right end surface close to the lock knob 602a and perpendicular to the side wall surface of the interlocking hook accommodating groove 6026 a. The locking hook 6032a is substantially hammer-shaped and includes a hook shank and a hook body which are integrally formed, and a receiving groove for the locking hook return spring is formed in the bottom of the hook body and the lower portion of the hook shank along the extending direction of the hook shank; a mounting hole is formed in the direction perpendicular to the side wall surface of the accommodating groove of the locking hook return spring on the hook body of the locking hook, and the locking hook 6032a and the locking hook return spring 6033a are mounted on the lock knob 602a through a connecting pin penetrating through the pin hole 6024 a; the free end of the hook stem of the latch hook 6032a faces the bottom of the latch hook receiving groove 6026 a; the upper portion of the hook body of the locking hook 6032a can be adapted to the locking ring table 2031a (the structure and installation of the locking hook can directly adapt to the locking ring table 2031a without rotating a lock knob (computer key) by the action of the locking hook return spring 6033a in the locking process).

The second ID chip 2034a is electrically connected to the travel switch 10c via a connecting lead. When the travel switch 10c is turned on (i.e., the travel switch control spring 10a abuts against the travel switch), the second ID code chip 2034a and the travel switch 10c form a closed electronic loop, and when the annular ground wire lock is operated by a computer key, the code value of the second ID code chip 2034a can be read to perform unlocking operation; when the travel switch 10c is turned off (i.e., when the travel switch control spring 10a is moved away from the travel switch), the code value of the second ID code chip 2034a is invalidated due to the electronic circuit being cut off, and when the circular ground lock is operated by the computer key, the authorized operation of the computer key is rejected due to the code value of the second ID code chip 2034a being invalidated.

As shown in fig. 25, when the ground wire latch is locked, the ground wire latch makes the hanging end 12a of the temporary ground wire 11a and the ground end 13a connected end to form a ring shape, so that the length of the temporary ground wire 11a cannot meet the hanging requirement, i.e. the temporary ground wire 11a is in a state of being unable to be turned back; meanwhile, the first ID chip 2032a in the first wire clamping portion is hidden between the left side wall of the first chip holder 203a and the right side wall of the lock body 1a, and cannot be read by a computer key, indicating that the temporary grounding wire is in an un-hooked state and in an unavailable state. The possibility of illegal operation is eliminated, the temporary grounding wire is confirmed to be removed, and the correctness of the whole operation is guaranteed compulsorily. Meanwhile, when the ring buckle ground wire lock is in a locking state, the mounting screws are hidden, namely the ring buckle ground wire lock adopts a totally enclosed structural design, cannot be disassembled, and has reliable prying resistance, shearing resistance and impact resistance.

As shown in fig. 26, the ground wire lock of the ring buckle is unlocked by a computer key (not shown), and the computer key cannot be taken out in the unlocked state; when the buckle ground wire lock is unlocked, the first wire clamp part 2a in the buckle ground wire lock can be pulled out from the lock body 1a and separated from the lock body 1a, the first ID code chip 2032a of the first wire clamp part 2a can be read by a computer key, the temporary grounding wire is shown to be in an unretracted or hooked state, the working personnel is reminded to recover or remove, and the anti-dismantling leakage is realized.

1) when the temporary grounding wire and the unlocking device are unlocked

As shown in fig. 13, 23, 24 and 26, in the ring-shaped ground line lock in the locked state, the first wire clip part 2a is matched with the locking hook 6032a in the lock body 1a through the locking ring platform 2031a in the first code piece seat 203a, so as to be firmly closed in the first accommodating groove 4 a. At this time, the self-locking sleeve 6031a is pushed to be close to the return torsion spring catch plate 6023a under the action of the first clamp part 2a, and the notch 6031c at the bottom of the groove 6031b at the right end of the self-locking sleeve 6031a has no restraining effect on the locking hook 6032 a. Meanwhile, under the action of the stroke switch control spring 10a in the boss 6031d at the bottom of the self-locking sleeve 6031a, the stroke switch 10c is switched on, the second ID code chip 2034a is in a closed electronic loop state, and the second ID code chip 2034a can authorize unlocking of the computer key.

When the computer key is used to unlock, the lock knob 602a can rotate in the circumferential direction (in this embodiment, the lock knob can rotate 65 °), and the locking hook 6032a is driven to rotate. When the knob 602a rotates 65 °, the knob 602a drives the locking hook 6032a to be located in the sector indentation 2035a of the locking circular hole on the first cable clamp portion 2 a. At this time, the self-locking sleeve 6031a moves rightward under the action of the self-locking sleeve return torsion spring 6025a and ejects the first wire clamp portion 2a (i.e., the annular ground wire lock is successfully unlocked).

Meanwhile, after the unlocking operation of the computer key is finished,

under the action of the lock knob reset torsion spring 6022a, the lock knob 602a performs a corresponding reset action. At this time, under the action of the lock knob reset torsion spring 6022a, the locking hook 6032a enters the notch 6031c of the self-locking sleeve 6031a, and the lock knob 602 can not rotate freely any more due to the constraint of the locking hook 6032a, thereby realizing the function of automatic locking after unlocking.

Meanwhile, as the self-locking sleeve 6031a moves rightwards, the travel switch control spring 10a on the boss at the bottom of the self-locking sleeve 6031a leaves the travel switch 10c, so that the electronic circuit of the second ID code chip 2034a is in a cut-off state and cannot generate an effective code value, and a computer key cannot unlock the unlocked annular ground wire lock, thereby perfectly realizing the functions of mechanical self-locking and intelligent self-locking in an unlocking state.

At this time, the loop ground wire lock is in an unlocked state, the first clip part 2a is separated from the loop ground wire lock main body, and the first ID code chip 2032a can be read by a computer key, so that whether the hanging position of the temporary ground wire main body 11a corresponds to the temporary ground pile or not is determined.

2) When the temporary grounding wire and the unlocking device are locked

When the locking hook 6032a is movably arranged in the locking hook receiving groove 6026a, as shown in fig. 13, 23, 24 and 25, the first wire clip part 2a is inserted into the first receiving groove 4a, the self-locking sleeve 6031a is pushed to be close to the return torsion spring clamping plate 6023a due to the action of the first wire clip part 2a, and the notch 6031c at the bottom of the groove 6031b at the right end of the self-locking sleeve 6031a has no restraining effect on the locking hook 6032 a; at this time, the travel switch control spring 10a at the bottom of the self-locking sleeve 6031a acts to turn on the travel switch, so that the second ID code chip 2034a generates a valid code value, and then the computer key can perform authorized locking operation. In the process of closely fitting the first wire clamp portion 2a to the first receiving groove 4a (i.e., in the process of moving the locking hook 6032a forward (without rotation)), the locking hook 6032a rotates around the connecting pin passing through the pin hole 6024a as a rotation axis by being pressed by the locking ring stand 2031a, and the hook body partially or completely enters the locking hook receiving groove 6026a downward. Until the first clip portion 2a is tightly attached to the first receiving groove 4a, the locking hook return spring 6033a makes the hook body of the locking hook 6032a pop up to match with the locking ring platform 2031a in the first clip portion 2a, i.e. the locking hook 6032a firmly locks the first clip portion 2a in the first receiving groove 4a (i.e. the annular ground wire lock is in a locked state). At this time, the latch ground wire lock is in a locked state, and the temporary ground wire 11a is in an unavailable state in an end-to-end connection mode.

Of course, when the locking hook 6032a is directly and fixedly arranged at the right end of the lock knob 602a, as shown in fig. 13, 23, 24 and 25, the first clip part 2a is inserted into the first accommodating groove 4a, the self-locking sleeve 6031a is pushed to be close to the return torsion spring snap-gauge 6023a due to the action of the first clip part 2a, and the notch 6031c at the bottom of the groove 6031b at the right end of the self-locking sleeve 6031a has no constraint effect on the locking hook 6032 a; at this time, the travel switch control spring 10a at the bottom of the self-locking sleeve 6031a acts to turn on the travel switch, so that the second ID code chip 2034a generates a valid code value, and then the computer key can perform authorized locking operation, and drive the lock knob 602a, and further drive the locking hook 6032a to rotate, so that the locking hook 6032a is adapted to the locking ring platform 2031a in the first wire clamp portion 2a, that is, the locking hook 6032a firmly locks the first wire clamp portion 2a in the first accommodating groove 4a (i.e., the annular ground wire lock is in a locked state). At this time, the latch ground wire lock is in a locked state, and the temporary ground wire 11a is in an unavailable state in an end-to-end connection mode.

2) an operator carries a computer key and a corresponding temporary grounding wire (a ring buckle grounding wire lock) to go to the site;

3) an operator opens a group of ring buckle ground wire locks of the temporary ground wires by using a computer key (the operator can unlock the ring buckle ground wire locks after the computer key is successfully calibrated with second ID code pieces of the ring buckle ground wire locks), and the computer key is used for reading first ID code pieces of the ring buckle ground wire locks in the temporary ground wires to be hung;

7) after all the operation tasks are completed, the operator returns to the master control room, returns the computer key and returns task information.

Step 3), the middle buckle ground wire lock is provided with a first ID code piece of an identity label and represents the identity of the temporary grounding wire; the first ID code chip is positioned in a first wire clamping part of the ground wire lock, and the first wire clamping part is used for fixing a hanging connection end of the temporary ground wire and can be read by a computer key only when the ring buckle ground wire lock is in an open state.

And an operator generates an operation ticket in the five-prevention host according to the operation task simulation. In the operation process, an operator opens the annular ground wire lock by using a computer key, reads a first ID code chip in the annular ground wire lock by using the computer key, and binds and corresponds the temporary grounding wire and the hanging point (temporary grounding pile). Then the operating personnel opens the locking lockset of the grounding pile, articulates the temporary grounding wire, and then restores the locking of the temporary grounding pile to achieve the functions of preventing the temporary grounding from being hung and mistakenly hanging. After all operations are finished, the operator returns to the master control room and returns the computer key operation information. At the moment, the five-prevention host records the ID code of the annular ground wire lock and the information of the hitching point. Each hanging connection point corresponds to a temporary grounding wire.

A control method for preventing misoperation by utilizing the control system for preventing electrical misoperation comprises the following steps in the temporary grounding wire dismantling stage:

3) an operator reads a first ID code chip in a first wire clamp part of a hanging end of the temporary grounding wire by using a computer key to confirm the identity of the temporary grounding wire;

4) after confirming that the hung temporary grounding wire is matched with the temporary grounding pile, an operator opens a locking lockset of the temporary grounding pile of the grounding point by using a computer key, removes the temporary grounding wire and restores the temporary grounding pile to be locked after the temporary grounding wire is removed;

5) an operator uses a computer key to lock the ring buckle ground wire lock of the temporary ground wire; taking down the computer key;

7) the operator returns the computer key and returns the task information.

In the temporary grounding wire dismantling operation, the five-prevention host synchronously sends the ID codes of the annular grounding wire locks corresponding to the grounding points to the computer key when an operator simulates operation. Before an operator removes the anti-misoperation lockset of the temporary grounding point, the hanging end of the temporary grounding line must be removed, the first ID code piece of the annular grounding line lock is read through a computer key (if the hanging end of the temporary grounding line is not removed, information in the first ID code piece cannot be read, so that the temporary grounding line can be ensured to be removed), namely the identity of the temporary grounding line is confirmed (whether the removal place is correct or not is confirmed, and the temporary grounding line is prevented from being removed by mistake). Then, an operator opens the ground point locking lockset, removes the temporary ground line, and locks the annular ground line lock (after removing the ground line hanging end 12, the ground end 13 is required to be removed to lock the annular ground line lock, so that the leakage prevention is realized). And when all the operation tasks are finished, returning the operation information to the computer key. The five-prevention host can check the operation information of the computer key according to the operation task, and can finish the current operation task when the returned operation information corresponds to the hanging point and the temporary grounding wire.

According to the invention, through the structure of the buckle ground wire lock, when a worker removes the ground wire, the identity of the temporary ground wire can be read only by removing the hanging end of the temporary ground wire, so that the possibility of illegal operation and the possibility of missing removal are solved, namely the correctness of the whole operation is forcibly ensured through the control method.
