Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and transformation, in particular to a ground wire grounding lock and a ground wire grounding lock system using the same. Background Art

[0002] In order to maintain the safety of power grid operation, lines and electrical equipment need to be inspected before commissioning or undergo regular inspection and maintenance. During the inspection and maintenance of electrical equipment, in order to ensure the life safety of operators, temporary grounding wires need to be hung before inspection and maintenance, which can also ensure the safety of the entire power grid during power transmission after inspection and maintenance.

[0003] In the existing technology, a mechanical lock is usually installed at the ground wire joint or the grounding pile hole, and the connection or removal status of the ground wire is judged only by the operation of the mechanical lock locked by the computer key (it is possible that the lock is operated by the computer key, but the ground wire is not actually connected), so it is impossible to judge whether the temporary ground wire is actually connected to the ground wire pile. In addition, some temporary ground wires use a ground wire status collector to collect the connection status of the temporary ground wire. The status collector is installed on the ground wire head of the temporary ground wire (that is, the end connected to the grounding pile). There is a power supply and a magnetic induction device (such as a reed switch) in the status collector. A magnet is provided on the ground wire pile. When the status collector is close to the ground wire pile, the magnetic induction device senses the magnet and generates an induction signal. The signal is fed back to the computer key and the anti-error system through the power supply and wireless communication equipment, so as to determine the connection status of the ground wire through the generation of the induction signal. Although the status collector realizes the real-time collection of the connection or removal status of the ground wire, the collector can only reflect the proximity distance between the ground wire head and the ground wire pile, and cannot reflect that the ground wire head is locked on the ground wire pile, and cannot accurately feedback the connection or removal status of the temporary ground wire. If the operator goes through the empty process (the collector collects the status of the ground wire pile, but the temporary ground wire is not actually connected to the ground wire pile), the temporary ground wire is not actually connected to the ground wire pile, and safety accidents are likely to occur when repairing electrical equipment. Secondly, after the maintenance is completed, the ground wire needs to be removed before power can be supplied to the electrical equipment, but if the ground wire is forgotten to be removed (the ground wire removal status is not obtained, and the ground wire is not actually removed) and power is supplied directly, a short circuit accident will occur, damaging the power equipment and grid facilities.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0046] The following is combined with Figures 1 to 8The technical solution of the utility model is further illustrated by specific implementation methods.

[0047] A grounding lock for grounding wires, used to lock a grounding wire assembly 200 on a grounding wire pile 300, the grounding lock 100 comprising a lock body 1, a first unlocking assembly 2, a lock tongue 3, a first travel switch 4, a second travel switch 5 and a PCB control board 6, the lock body 1 being provided with a locking structure for locking the grounding wire assembly 200;

[0048] The lock body 1 is provided with a ground wire insertion cavity 11, a lock tongue cavity 12 and a first unlocking cavity 13 which are interconnected, the ground wire insertion cavity 11 and the lock tongue cavity 12 are perpendicular to each other, and the first unlocking cavity 13 and the lock tongue cavity 12 are perpendicular to each other;

[0049] The lock tongue 3 is movably disposed in the lock tongue cavity 12, and the left end of the lock tongue 3 can be telescopically protruded from the ground wire insertion cavity 11. When the left end of the lock tongue 3 protrudes from the ground wire insertion cavity 11, it is in a locked state, and when the left end of the lock tongue 3 completely leaves the ground wire insertion cavity 11, it is in an unlocked state.

[0050] The first unlocking component 2 is movably disposed in the first unlocking cavity 13, and the first unlocking component 2 can drive the lock tongue 3 to switch between the locked state and the unlocked state by moving up and down;

[0051] The first triggering portion 41 of the first travel switch 4 can protrude telescopically from the ground wire insertion cavity 11;

[0052] The second triggering portion 51 of the second travel switch 5 can be telescopically protruded from the first unlocking cavity 13, and the first unlocking component 2 is provided with a locking sensing portion 221 for accommodating the second triggering portion 51;

[0053] The first travel switch 4 and the second travel switch 5 are electrically connected to the PCB control board 6 respectively.

[0054] The present application provides a ground wire grounding lock 100, which is used to lock a ground wire assembly 200 on a ground wire pile 300 or unlock the ground wire assembly 200 from the ground wire pile 300 (after unlocking, the ground wire assembly 200 can be separated from the ground wire pile 300). The grounding lock 100 of the utility model comprises a lock body 1, a first unlocking component 2, a lock tongue 3, a first travel switch 4, a second travel switch 5 and a PCB control board 6; the lock tongue 3 can be movably arranged in the lock tongue cavity 12 of the lock body 1, and one end of the lock tongue 3 can extend from the lock tongue cavity 12 to the ground wire insertion cavity 11, and the lock tongue 3 is used to lock the ground wire insertion cavity 11 through the part protruding from the ground wire insertion cavity 11 to prevent an uncertified ground wire component 200 from being inserted into the lock body 1; when the lock tongue 3 moves to the right to completely leave the ground wire insertion cavity 11, it indicates that the grounding lock 100 is in an unlocked state, and the ground wire component 200 can be inserted into the lock body, and the ground wire component 200 is locked by the locking structure in the lock body 1 to achieve the hanging of the ground wire.

[0055] The first unlocking component 2 is arranged in the first unlocking cavity 13 which is perpendicular to the lock tongue cavity 12, and can move up and down in the first unlocking cavity 13. Through the up and down movement of the first unlocking component 2, the lock tongue 3 can be moved between the locked state and the unlocked state. When the first unlocking component 2 moves downward, it can drive the lock tongue 3 to move to the right, so that the left end of the lock tongue 3 completely leaves the ground wire insertion cavity 11 to the right. At this time, the ground wire grounding lock 100 is in the unlocked state, and the ground wire component 200 can be inserted into the ground wire insertion cavity 11; when the first unlocking component 2 is restored upward, the lock tongue 3 moves to the left until the left end of the lock tongue 3 is restored to protrude from the ground wire insertion cavity 11. At this time, the ground wire grounding lock 100 is in the locked state, and the ground wire component 200 cannot be inserted into the ground wire insertion cavity 11.

[0056] The grounding lock 100 also includes a first travel switch 4 and a second travel switch 5. By setting the first travel switch 4 as a detection component for the insertion state of the grounding assembly 200, when the grounding assembly 200 is inserted into the grounding insertion cavity 11, the grounding assembly 200 will squeeze and compress the first triggering portion 41 protruding from the grounding insertion cavity 11, which serves as a signal of the hooking state S11 of the grounding assembly 200; when the grounding assembly 200 is withdrawn from the grounding insertion cavity 11, the first triggering portion 41 resumes the extended state, which serves as a signal of the removal state S12 of the grounding assembly 200. Similarly, by setting the second travel switch 5 as the detection component of the unlocked state of the grounding lock 100, since the first unlocking component 2 is provided with a locking sensing part 221 accommodating the second trigger part 51, when the first unlocking component 2 moves downward in the first unlocking cavity 13, the locking sensing part 221 is separated from the corresponding second trigger part 51, and the first unlocking component 2 will squeeze and compress the second trigger part 51, which is used as a signal of the unlocked state S21 of the grounding lock 100; when the first unlocking component 2 moves upward and resets to the position where the locking sensing part 221 corresponds to the second trigger part 51, the second trigger part 51 resumes the extended state, which is used as a signal of the locked state S22 of the grounding lock 100. The PCB control board 6 receives the feedback signals of the first travel switch 4 and the second travel switch 5, and accurately feeds back the hooking / removal signal of the grounding component 200 and the unlocking / locking signal of the grounding lock 100 to the upper computer connected to the PCB control board 6. It is worth mentioning that when the PCB control board 6 receives the S21 signal of the ground wire grounding lock, although it indicates that the ground wire grounding lock 100 is in an unlocked state, it does not mean that the ground wire grounding lock 100 is completely unlocked and the ground wire assembly 200 can be inserted to achieve hanging. The S21 signal only represents an unlocking process and is used as a reference to remind the operator or monitoring personnel of the status of the ground wire grounding lock.

[0057] By arranging a first travel switch 4 and a second travel switch 5 in the lock body 1 to respectively detect the connection status of the ground wire grounding lock 100 (ground wire pile 300) and the ground wire assembly 200, and by sending the status of the two travel switches for feedback to the host computer through the PCB control board 6, on the one hand, it can solve the problem that the magnetic induction device used as a status collector has a sensing error and cannot accurately reflect the state of the ground wire hanging / removal; on the other hand, compared with the previous state of the ground wire lock with status, the feedback of the hanging / removal state needs to be uploaded to the host computer through the computer key. In this solution, the PCB control board 6 can be used to feedback and receive relevant status and instructions to the host computer.

[0058] Furthermore, the grounding lock further comprises an electromagnet 71, a power indicator light 72 and an electromagnet power supply;

[0059] The power indicator light 72 is electrically connected to the electromagnet power supply, and the power indicator light 72 is arranged outside the lock body 1;

[0060] The electromagnet 71 is disposed below the first unlocking component 2. When the moving iron core of the electromagnet 71 is in a released state, it blocks the first unlocking component 2 from unlocking the lock tongue 3.

[0061] The electromagnet 71 , the power indicator light 72 and the electromagnet power supply are electrically connected to the PCB control board 6 respectively.

[0062] In order to avoid the potential safety hazards caused by incorrect or missing ground information and further reduce the misconnection operation of the grounding lock, the grounding lock 100 provided in this embodiment further includes an electromagnet 71, a power indicator light 72 and an electromagnet power supply, and the electromagnet power supply is controlled by the PCB control board 6 to supply power to the electromagnet 71 and the power indicator light 72. The electromagnet 71 is electrically connected to the PCB control board 6. In the power-on state, when the PCB control board 6 receives the unlocking state S21 signal of the second travel switch 5, the electromagnet 71 is started, and its moving iron core is attracted, so that the second unlocking component 8 can continue to move downward and drive the lock tongue 3 to move rightward to realize the unlocking of the grounding lock 100; in the non-powered state, even if the second unlocking component 8 can move downward at the beginning, because the moving iron core of the electromagnet 71 is in the released state, the moving iron core is below the second unlocking component 8 to block it from continuing to move downward, and the grounding lock is unlocked.

[0063] Furthermore, a block 31 is provided at the left end of the locking tongue 3 for engaging with or separating from the ground wire assembly 200 .

[0064] In this embodiment, after the ground wire assembly 200 is inserted into the ground wire insertion cavity 11, the locking structure for locking the ground wire assembly 200 is a block 31 arranged at the left end of the lock tongue 3. As shown in the accompanying drawings, the block 31 has a simple structure and is easy to process. To further illustrate, when the lock tongue 3 is in the unlocked position, the ground wire assembly 200 can be inserted into the ground wire insertion cavity 11. When the ground wire assembly 200 moves to the locked position in the ground wire insertion cavity 11, the block 31 of the lock tongue 3 resumes protruding into the ground wire insertion cavity 11 and locks the ground wire assembly 200. When the ground wire assembly 200 needs to be removed, the lock tongue 3 is driven to the unlocked position by the first unlocking assembly 2, the block 31 is disengaged from the locking of the ground wire assembly 200, and after the block 31 is disengaged from the ground wire insertion cavity 11, the ground wire assembly 200 can be removed from the lock body 1.

[0065] Furthermore, the first unlocking assembly 2 includes a reset button 21 and an unlocking rod 22, wherein the reset button 21 is disposed outside the lock body 1, the bottom of the reset button 21 is connected to the unlocking rod 22, and the unlocking rod 22 is movably disposed in the first unlocking cavity 13;

[0066] The unlocking rod 22 includes the locking sensing portion 221 and the lock tongue accommodating portion 222. The locking sensing portion 221 is located at the upper portion of the unlocking rod 22. The lock tongue accommodating portion 222 is a columnar extension portion eccentrically arranged at the lower end of the unlocking rod 22. The columnar extension portion is close to one side of the ground wire insertion cavity 11. The diameter of the connection between the columnar extension portion and the unlocking rod 22 gradually decreases from top to bottom.

[0067] A shifting groove 32 is provided in the middle of the lock tongue 3, and the unlocking rod 22 can move up and down in the shifting groove 32. In the locked state, the second triggering portion 51 is located at the locking sensing portion 221, and the lock tongue accommodating portion 222 is located at the shifting groove 32; in the unlocked state, the second triggering portion 51 is disengaged from the locking sensing portion 221, and the lock tongue accommodating portion 222 is disengaged from the shifting groove 32 downward.

[0068] The first unlocking component 2 includes a reset button 21 and an unlocking rod 22. The upper part of the reset button 21 protrudes from the lock body 1 to facilitate pressing operation thereon. The bottom of the reset button 21 is connected to the unlocking rod 22. The unlocking rod 22 is movably arranged up and down in the first unlocking cavity 13. Pressing the reset button 21 outside the lock body 1 will drive the unlocking rod 22 to move downward in the first unlocking cavity 13. When the force on the reset button 21 is removed, the reset button 21 will drive the unlocking rod 22 to reset upward.

[0069] The unlocking rod 22 includes a locking sensing portion 221 and a lock tongue accommodating portion 222. The locking sensing portion 221 is located at the upper part of the unlocking rod 22, which is equivalent to a notch that is axially recessed toward the unlocking rod 22, and is used to accommodate the second triggering portion 51 of the second travel switch 5, so that when the second triggering portion 51 is at the corresponding position of the locking sensing portion 221, the second triggering portion 51 is in a normal release state, so that the second travel switch 5 is in an off state. The lock tongue accommodating portion 222 is a columnar extension portion eccentrically arranged at the lower end of the unlocking rod 22, and the columnar extension portion is arranged close to one side of the ground wire insertion cavity 11, and the rod width of the columnar extension portion is smaller than the normal width of the unlocking rod 22, so that when the lock tongue 3 is at the position of the lock tongue accommodating portion 222 of the unlocking rod 22, the lock tongue 3 is offset as a whole toward the direction of the ground wire insertion cavity 11, so that the left end of the lock tongue 3 in this state protrudes from the ground wire insertion cavity 11. When the unlocking rod 22 moves downward, the lock tongue accommodating portion 222 exits the lock tongue cavity 12 downward, and the width of the unlocking rod 22 increases from small to large, gradually pushing the lock tongue 3 to move to the right until the left end of the lock tongue 3 completely exits the ground wire insertion cavity 11, thereby unlocking the ground wire grounding lock 100.

[0070] To further illustrate, the diameter of the connection between the columnar extension and the unlocking rod 22 gradually decreases from top to bottom, showing a smooth transition, so that the unlocking rod 22 can move up and down stably.

[0071] Furthermore, the lock tongue 3 also includes a lock tongue spring 33, and the other end of the lock tongue 3 is pressed against the right end of the lock tongue cavity 12 through the lock tongue spring 33, and the lock tongue spring 33 is used to drive the lock tongue 3 to move from the unlocked state to the locked state.

[0072] When the unlocking lever 22 is pressed downward, the unlocking lever 22 applies a force to the right on the lock tongue 3, causing the lock tongue 3 to move from the locked state to the unlocked state. During the unlocking process, the lock tongue 3 compresses the lock tongue spring 33 at the right end. When the force pressing the unlocking lever 22 is removed, which is equivalent to removing the force acting on the lock tongue 3 to the right, the compressed lock tongue spring 33 recovers to the left, pushing the lock tongue 3 to return to the left, and the lock tongue 3 moves from the unlocked state to the locked state.

[0073] Furthermore, the first trigger portion 41 is located at the end of the ground wire insertion cavity 11 .

[0074] The first trigger part 41 is disposed at the end of the ground wire insertion cavity 11, and can effectively reflect the hooking / removal status of the ground wire assembly 200. Only when the ground wire assembly 200 is completely inserted into the ground wire insertion cavity 11, and the end of the ground wire assembly 200 reaches the first trigger part 41 at the end of the ground wire insertion cavity 11, can the first travel switch 4 obtain the S11 signal.

[0075] Furthermore, the grounding lock further comprises a second unlocking component 8, which drives the lock tongue 3 to move between the locked state and the unlocked state under the direct or indirect control of a driving source.

[0076] The driving source can be a mechanical key, a computer key, an electric driving mechanism, an electromagnetic driving mechanism, a pneumatic driving mechanism or other common driving mechanisms. The grounding lock 100 in this embodiment includes two unlocking components. After the first unlocking component 2 receives the unlocking command from the host computer through the PCB control board 6, it drives the lock tongue 3 to unlock by pressing the reset button 21 (unlocking rod 22); the second unlocking component 8 is used for local unlocking when the first unlocking component 2 cannot be used for remote monitoring and unlocking, thereby improving the practicality and safety of the grounding lock 100.

[0077] Furthermore, the second unlocking assembly 8 includes a lock core 81 and a toggle member 82, and the lock tongue 3 is provided with a toggle groove 34 that cooperates with the toggle member 82;

[0078] The toggle member 82 includes a mounting portion 821 and a toggle portion 822 , wherein the mounting portion 821 is used for mounting and connecting with the lock core 81 , and the toggle portion 822 protrudes toward the toggle slot 34 .

[0079] The second unlocking component 8 can be realized by a variety of different specific structures, which at least includes a lock core 81 and a toggle member 82. After the key is successfully matched, the lock core 81 can rotate and drive the toggle member 82 to rotate; the toggle member 82 protrudes toward the toggle groove 34 of the lock tongue 3 by the toggle portion 822. During the rotation of the toggle member 82, the toggle portion 822 drives the lock tongue 3 to move to the right in the toggle groove 34, and moves from a locked state to an unlocked state.

[0080] A ground wire and grounding lock system, comprising a ground wire assembly 200, a ground wire pile 300, a host computer and the ground wire and grounding lock 100;

[0081] The ground wire grounding lock 100 is fixedly installed on the ground wire pile 300 and is used to lock the ground wire assembly 200 hung on the ground wire pile 300;

[0082] The host computer is connected to the ground wire grounding lock 100 via wire or wirelessly, and is used to send an unlocking instruction to the ground wire grounding lock 100, and to receive the unlocking / locking status of the ground wire grounding lock 100 and the hanging / removal status of the ground wire assembly 200.

[0083] Furthermore, the ground wire assembly 200 is provided with a locked structure, and the locked structure is a slot 201 provided at one end of the ground wire assembly 200 inserted into the ground wire insertion cavity 11 , and the clamping block 31 is engaged with or separated from the slot 201 .

[0084] In this embodiment, when the lock tongue 3 is in the unlocked position, the ground wire assembly 200 can be inserted into the ground wire insertion cavity 11, and when the ground wire assembly 200 moves to the locked position in the ground wire insertion cavity 11, the locking block 31 of the lock tongue 3 resumes protruding into the ground wire insertion cavity 11 and faces the locking slot 201 of the ground wire assembly 200, thereby locking the ground wire assembly 200. The locking block 31 of the lock tongue 3 is inserted into the locking slot 201 of the ground wire assembly 200 or separated from the locking slot 201.

[0085] It is worth noting that the shape and structure of the slot 201 and the block 31 can also be diversified, as long as the block 31 cooperates with the slot 201 to interfere with the axial movement of the slot 201 along the ground wire assembly 200, so that the ground wire assembly 200 cannot be separated from the ground wire insertion hole 11.

[0086] In summary, the working principle of the ground wire to ground lock / ground wire to ground lock system provided in the above embodiments is as follows:

[0087] 1. Realize ground wire hooking through the first unlocking component:

[0088] The upper computer sends an unlocking command to the grounding lock 100, and the PCB control board 6 receives the command. After the electromagnet 71 is powered on, the power indicator light 72 lights up. At this time, the first unlocking component 2 is pressed downward, and the second triggering part 51 is disengaged from the locking sensing part 221. The second triggering part 51 is squeezed to the left by the first unlocking component 2, triggering the second travel switch 5 to close (S21), and then triggering the moving iron core of the electromagnet 71 to be attracted, and the moving iron core no longer blocks the first unlocking component 2 from moving downward; the first unlocking component 2 continues to move downward and drives the lock tongue 3 to move to the right, so that the left end of the lock tongue 3 is disengaged from the grounding insertion cavity 11. At this time, the grounding component 200 can be inserted into the grounding insertion cavity 11. When the grounding component 200 is inserted into the lock body 1, the grounding component 2 00 will touch and squeeze the first trigger part 41, triggering the first travel switch 4 to close (S11). At this time, the force pressing down on the first unlocking component 2 is released, the first unlocking component 2 recovers upward, and the second trigger part 51 recovers and extends to the locking sensing part 221, triggering the second travel switch 5 to be in the disconnected state (S22), and then triggering the moving iron core of the electromagnet 71 to recover to the released state. At this time, the first unlocking component 2 is in the reset state, and the lock tongue 3 also moves to the left to the reset state. At the same time, the card slot 201 of the grounding component 200 is locked by the card block 31 at the left end of the lock tongue 3. The PCB control board 6 combines the hanging state (S11) of the grounding component 200 and the locking state (S22) of the grounding lock, and sends the combined state to the upper computer. After receiving that the grounding lock 100 is in the S11 hanging state, the upper computer sends a locking command, and the PCB control board 6 cuts off the power supply of the electromagnet, and the power indicator light 72 goes out. At this point, the hanging process of the grounding component 200 is completed.

[0089] 2. Remove the ground wire through the first unlocking component:

[0090] The upper computer sends an unlocking command to the grounding lock 100, and the PCB control board 6 receives the command. After the electromagnet 71 is powered on, the power indicator light 72 lights up. At this time, the first unlocking component 2 is pressed downward, and the second triggering part 51 is disengaged from the locking sensing part 221. The second triggering part 51 is squeezed to the left by the first unlocking component 2, triggering the second travel switch 5 to close (S21), and then triggering the moving iron core of the electromagnet 71 to be attracted, and the moving iron core no longer blocks the first unlocking component 2 from moving downward; the first unlocking component 2 continues to move downward and drives the lock tongue 3 to move to the right, so that the block 31 at the left end of the lock tongue 3 is disengaged from the card slot 201 of the grounding component 200, and withdraws from the grounding insertion cavity 11. At this time , pull the ground wire assembly 200 out of the ground wire insertion cavity 11, then the pressure of the first trigger part 41 is cancelled, and the first travel switch 4 is disconnected (S12). At this time, the force pressing down on the first unlocking assembly 2 is released, the first unlocking assembly 2 recovers upward, and the second trigger part 51 recovers and extends to the locking sensing part 221, triggering the second travel switch 5 to be in the disconnected state (S22), and then triggering the moving iron core of the electromagnet 71 to recover to the released state, and at this time, the first unlocking assembly 2 is in the reset state, and the lock tongue 3 is also in the reset state. The PCB control board 6 merges the removal state (S12) of the ground wire assembly 200 and the locking state (S22) of the ground wire grounding lock 100, and sends the merged state to the upper computer. After receiving that the ground wire grounding lock 100 is in the S12 hanging state, the upper computer issues a locking command, and the PCB control board 6 cuts off the power supply to the electromagnet, and the power indicator light 72 goes out. At this point, the removal process of the ground wire assembly 200 is completed.

[0091] 3. Realize ground wire hooking through the second unlocking component:

[0092] The operator uses a mechanical key (including a computer key and a universal unlocking key) to manually mechanically unlock the second unlocking component. After the key matches the lock core 81, the toggle member 82 rotates to drive the lock tongue 3 to move to the right to unlock the device. At this time, the ground wire component 200 is inserted into the ground wire insertion cavity 11, and the first travel switch 4 is triggered to close, triggering the ground wire hanging state (S11). Then the key is manually returned to lock the device, and the lock tongue 3 moves to the left until the card block 31 is engaged with the card slot 201 of the ground wire component 200. The ground wire component 200 completes the ground wire hanging and the ground wire grounding lock 100 completes the locking. If the communication is normal, the hanging state of the ground wire component 200 is fed back to the upper computer through the PCB control board 6 in real time.

[0093] 4. Remove the ground wire through the second unlocking component:

[0094] The operator uses a mechanical key (including a computer key and a universal unlocking key) to manually mechanically unlock the second unlocking component. After the key matches the lock core 81, the toggle member 82 rotates to drive the lock tongue 3 to move to the right, and the block 31 of the lock tongue 3 disengages from the card slot 201 of the ground wire component 200 to achieve unlocking; at this time, the ground wire component 200 is pulled out of the ground wire insertion cavity 11, and the first travel switch 4 is triggered to disconnect, triggering the ground wire removal state (S12); then the key is manually returned to the position to lock, and the lock tongue 3 moves to the left until the left end protrudes into the ground wire insertion cavity 11, then the ground wire component 200 is removed and the ground wire grounding lock 100 is locked. If the communication is normal, the removal state of the ground wire component 200 is fed back to the upper computer through the PCB control board 6 in real time.
