[0032] In recent years, with the power industry accelerating the construction of an intelligent power grid, the total length of overhead lines in the regional distribution network has been increasing continuously. As a result, the workload of power distribution line outage maintenance has increased sharply. Moreover, there are clear requirements in the power distribution safety regulations: when it is verified that there is no voltage during outage maintenance, the high-voltage power distribution lines and equipment under maintenance should be grounded and short-circuited in three phases immediately, and all ends of the working section and all branch lines within the working section that may have reverse power transmission should be grounded. Therefore, the demand for grounding wire devices in the power distribution line outage maintenance work has also increased accordingly. Especially in engineering projects such as the renovation and defect handling of old lines, when there are multiple points and multiple teams working, higher requirements are put forward for the convenience of grounding wire operation.
[0033] It is known that an existing patent discloses a variable angle grounding wire clamp and a method of using the same, with application number 201910653133.1, comprising a grounding rod, a rotating disk, a gear, a gear limiting mechanism and a wiring clamp. A clamp is provided at the top of the grounding rod, bolt assemblies are installed on both sides of the clamp, the clamp is fixedly connected to the grounding rod through the bolt assembly, a rotating pin is installed in the middle of the clamp, a rotating disk is fixedly installed in the middle of the rotating pin, two gears are coaxially fixedly arranged on both sides of the rotating disk with the rotating disk, a gear limiting mechanism is provided at the lower part of the two gears, the gear limiting mechanism comprises a limiting knife rod, a rotating seat, a pressure block and a small spring, there are two limiting knife rods in total, the middle parts of the two limiting knife rods are rotatably connected to the rotating seat welded on the grounding rod, the top of the limiting knife rod is clamped on the teeth of the gear, a pressure block is installed at the bottom end of the limiting knife rod, a small spring is installed between the bottom of the pressure block and the grounding rod, a wiring clamp is installed at the upper end of the rotating disk, and the wiring clamp comprises a fixed clamp, a fixed plate, a movable clamp, a large spring, a pull rope and a limit head, a fixed chuck is welded on a rotating disk, a fixed plate is welded on the bottom end of the fixed chuck, a movable chuck is arranged on the fixed plate, a large spring is installed between the bottom end of the movable chuck and the fixed plate, a pull rope is bolted to the bottom end of the movable chuck, a limit ring is arranged on one side of the grounding rod, the pull rope is passed through the limit ring, and a limit head is arranged at the bottom end of the pull rope, when the large spring is in a natural state, the movable chuck is just pressed together with the fixed chuck, and an arc-shaped slot is symmetrically provided on the bottom surface of the fixed chuck and the upper end surface of the movable chuck, In addition, a protrusion is provided on the surface of the arc-shaped slot, which can increase the friction force of the arc-shaped slot to make the clamping tighter. The small spring is in a compressed state in the initial state. A sliding groove is provided on the inner side of the fixed clamp, and one end of the movable clamp is slidably set in the sliding groove. The grounding rod, the limit knife rod and the pull rope are all made of insulating material. A grounding wire clamping head is provided on the fixed clamp, and the grounding wire clamping head can conveniently connect the grounding wire with the wiring clamp, so that the cable conductor, the wiring clamp and the grounding wire are connected to achieve grounding protection.
[0034] A method for using a variable angle grounding clamp comprises the following steps:
[0035] S1. Before use, connect the grounding wire to the wiring clamp through the grounding wire clamping head to make the wiring clamp and the grounding wire connected;
[0036] S2. When in use, the operator presses the pressure block downward, and the pressure block compresses the small spring, and the blade position at the other end of the limit knife rod is lifted up and separated from the gear. At this time, the wiring clamp is pulled, so that the rotating disk at the bottom of the wiring clamp drives the gear to rotate counterclockwise or clockwise under the action of the rotating pin shaft;
[0037] S3. When the wiring chuck is rotated relative to the grounding rod to the required angle, immediately release the pressing block, so that the small spring in the limit compression state generates a resilience force to abut against the bottom end of the limit cutter bar outward. At this time, an inward pressing force will be generated at the position of the cutter head at the top end of the limit cutter bar to tightly press and engage in the tooth groove of the gear, realizing the limit of the gear, and further realizing the fixation of the wiring chuck.
[0038] S4. Then hold the grounding rod by hand and pull the pull rope to compress the large spring, so as to separate the movable chuck from the fixed chuck, and then make the wire enter the arc-shaped card slot between the movable chuck and the fixed chuck.
[0039] S5. Finally, release the pull rope, and the large spring rebounds to push the movable chuck to move upward to clamp the wire together with the fixed chuck. In this way, the connection of the grounding wire, the wiring chuck and the cable wire can be realized, and the grounding protection can be achieved.
[0040] Working principle: During use, connect the grounding wire to the wiring chuck through the grounding wire clamping head, so that the wiring chuck and the grounding wire are connected and clamped tightly. Then clamp this device with the cable wire. When repairing or performing other work on the de-energized high-voltage equipment, when the high-voltage equipment suddenly comes back on or there is static electricity on other live equipment, the current on the equipment cable wire is introduced into the ground through the grounding wire clamp and the grounding wire, discharging the remaining charge after the equipment is powered off to ensure the personal safety of the maintenance personnel.
[0041] It is known that a prior patent has disclosed a grounding wire clamp for power equipment and its usage method, with the application number 202010991323.7, including a holding component and a pressing component. The pressing component is installed on the side of the holding component. Among them, the holding component facilitates the holding of the hand, and the pressing component is used to clamp the wire to be grounded. The holding component includes an insulating rod, an operating rod and a support rod. The support rod is rotatably installed inside the upper end of the insulating rod. Specifically, a groove is opened inside the upper end of the insulating rod, and the side wall of the insulating rod adjacent to the groove has a clearance fit with the lower part of the support rod. The groove facilitates the lower end of the support rod to extend into the inside of the insulating rod, which can play a role in limiting the support rod. A first bearing cooperating with the support rod is installed on the inner wall of the insulating rod adjacent to the groove. The first bearing facilitates the rotational connection between the insulating rod and the support rod, avoiding the rotation of the support rod when the insulating rod is rotated. The operating rod is rotatably installed inside the support rod. Specifically, a wiring post is installed on the side of the support rod through a screw. The wiring post facilitates the connection of the ground wire, and the wiring post is electrically connected to the middle plate of the pressing member. The lower section inside the support rod is hollow, and a second bearing cooperating with the operating rod is installed inside the side of the support rod. There are at least two second bearings. The at least two second bearings installed make the operating rod can be installed more stably inside the support rod. After installation, it should be ensured that the center line of the support rod is coaxial with the center line of the operating rod. The lower end of the operating rod extends out from the lower part of the support rod, and the lower end of the operating rod is connected to the upper end of the insulating rod.
[0042] An inner tube is installed at the lower part of the insulating rod. An outer tube is slidably sleeved on the outer side of the inner tube. A spring plunger is installed on the side part of the inner tube through bolts. A number of through holes matching with the spring plunger are formed in the side wall of the outer tube. During specific use, first press the spring plunger to make the spring plunger inside the outer tube, then pull the outer tube to adjust the distance between the lower end of the outer tube and the upper end of the inner tube, and then make the spring plunger protrude from the through hole to realize the fixation between the inner tube and the outer tube. And by adjusting the protrusion of the spring plunger from different through holes and adjusting the protruding length, the overall height can be adjusted, and the overall length can be adjusted according to the connection requirements. An outer convex part is arranged on the outer wall of the inner tube, a slideway matching with the outer convex part is arranged on the inner wall of the outer tube, the outer wall of the outer convex part is set as a smooth surface, the inner wall of the outer tube adjacent to the slideway is set as a smooth surface, and the cross section of the outer convex part is rectangular. By using the cooperation of the outer convex part and the slideway, when adjusting the relative sliding between the inner tube and the outer tube, limiting and guiding are carried out, so that the distance between the inner tube and the outer tube can be adjusted more smoothly. An insulating sleeve with a rough surface is adhesively bonded to the outer wall of the outer tube. The insulating sleeve is set as a rubber sleeve, which plays the roles of insulation, increasing the flexibility and friction of the hand holding. And the inner tube can be rotated by rotating the outer tube, thereby driving the insulating rod to rotate to realize the pressing or disengaging process. The pressing assembly includes a transmission part, a threaded rod, a support plate, two sliders and two pressing parts. The transmission part is installed at the upper end of the operating rod, and the threaded rod is rotatably installed on the side part of the support rod. Specifically, a third bearing matching with the threaded rod is installed on the side part of the support rod. The third bearing facilitates the rotation of the threaded rod. The threaded rod is connected with the transmission part. The support plate is installed on the upper side part of the support rod by means of screws and welding. The two sliders are respectively slidably installed on the lower part of the support plate. Specifically, a chute matching with the slider is formed in the lower part of the support plate. The chute facilitates the cooperation with the slider and is convenient for the sliding of the slider. The inner wall of the support plate adjacent to the chute is set as a smooth surface. The smoothly arranged chute helps to reduce the friction. The cross section of the chute is T-shaped. The two pressing parts are respectively installed on the lower parts of the two sliders through bolts. The two sliders are respectively threadedly connected to the outer side of the threaded rod. Specifically, threaded sections are arranged in the middle of the two sliders, and the thread directions of the two threaded sections are opposite. The threaded sections with opposite directions can realize the simultaneous approaching or separating movement of the two sliders during the forward and reverse rotation of the threaded rod, and can better realize clamping and disengaging. The transmission part includes a first bevel gear and a second bevel gear. The first bevel gear is key-connected to the upper end of the operating rod, and the second bevel gear is key-connected to the end side of the threaded rod. The first bevel gear meshes with the second bevel gear. The operating rod rotates following the rotation of the insulating rod, thereby driving the first bevel gear to rotate, making the second bevel gear rotate following the first bevel gear, and driving the threaded rod to rotate.The extruded part includes a concave connecting plate, two elastic plates and a pressing plate. The two elastic plates are respectively installed on the sides of the concave connecting plate by screws. The elastic plates are thin sheet arc-shaped steel plates with good elasticity. The pressing plate is installed between the two elastic plates by bolts. By using the elasticity of the elastic plates, the wire can be better pressed between the pressing plates. There is also a spring connected between the side of the pressing plate and the concave connecting plate, which can better increase the elasticity and achieve a good pressing effect. Specifically, several notches are provided on the side of the pressing plate, and the diameters of the several notches decrease successively from top to bottom. The notches are convenient for clamping the wire, and the diameters of the notches decreasing successively from top to bottom can meet the pressing of wires with various diameters.
[0043] A method for using a grounding wire clamp for electrical equipment grounding specifically includes the following steps:
[0044] S1: Connect the grounding wire. One end of the grounding wire is connected to the side of the support rod, and the other end of the grounding wire is connected to the conductor, and the conductor is inserted into the ground soil.
[0045] S2: Pre-adjustment. Rotate the insulating rod, use the transmission part for transmission, and drive the threaded rod to rotate, so that the two sliders move relatively, and then drive the two extruded parts to approach, so that the distance between the two extruded parts is 1 cm - 2 cm greater than the diameter of the wire to be connected.
[0046] S3: Press the wire. Hold the insulating rod by hand and move the whole, so that the wire to be connected is between the two extruded parts, and then continue to rotate the insulating rod, so that the two extruded parts press on the side of the wire, realizing the connection between the wire and the extruded parts and completing the grounding process.
[0047] S3: Disengagement. After use, reverse the insulating rod to make the two extruded parts disengage from both sides of the wire and complete the disengagement process.
[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0049] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0050] Embodiment 1
[0051] Refer to Figures 1-8As shown in the figure, this embodiment provides a grounding wire clamp, which includes a housing 1. A suspension bracket 4 is installed at the bottom of the housing 1, and the suspension bracket 4 is used to connect with a grounding rod. Rotating plates 2 are symmetrically arranged on both sides of the housing 1. A clamping head 3 is fixedly connected to the bottom of the rotating plate 2. A locking member is provided at the top of the clamping head 3. An adjusting mechanism for controlling the rotation of the rotating plate 2 is installed inside the housing 1. The adjusting mechanism is controlled by a sliding handle 6 symmetrically arranged on the outside of the housing 1, and the sliding handle 6 moves along the vertical direction of the housing 1.
[0052] During use, move the sliding handle 6 downward. The sliding handle 6 drives the adjusting mechanism to operate. The adjusting mechanism makes the two rotating plates 2 rotate in opposite directions, thereby driving the two clamping heads 3 to open, so that the wire is located between the two clamping heads 3. Release the sliding handle 6, and the adjusting mechanism runs in the reverse direction, thereby driving the two rotating plates 2 to rotate in the reverse direction. The two clamping heads 3 clamp the wire and fix the clamping heads 3 through the locking member, improving stability. The present invention does not need to use screws for fastening. It can be fixed on the wire by opening and closing the clamping heads 3. The operation is simple and convenient, and the work efficiency is high. And the two clamping heads 3 are fixed by using the locking member, further improving the stability and preventing loosening.
[0053] Furthermore, protective sleeves can be sleeved on the outside of the housing 1 and the clamping head 3 to prevent rainwater from damaging the internal parts and improve safety.
[0054] In a further optimized solution, the adjusting mechanism includes a moving block 11. Extrusion blocks 16 are symmetrically arranged on both sides of the moving block 11. The moving block 11 and the extrusion blocks 16 are connected by a number of hinge rods 15. When the moving block 11 moves downward, it drives the extrusion blocks 16 to move horizontally. A rotating component is in contact with the side wall of the extrusion block 16, and the rotating component is fixedly connected to the rotating plate 2. When the moving block 11 moves downward, the hinge rods 15 rotate, thereby driving the two extrusion blocks 16 to move in opposite directions. The extrusion blocks 16 extrude the rotating component, thereby causing the rotating plate 2 to rotate, facilitating the opening of the two clamping heads 3 for subsequent clamping work.
[0055] In a further optimized solution, the rotating component includes a connecting shaft 18. The rotating plate 2 is fixedly connected to the connecting shaft 18. Side plates 20 are respectively fixedly connected to both ends of the connecting shaft 18. A rotating roller 19 is rotatably connected between the two side plates 20. The rotating roller 19 is located at one end of the side plate 20 away from the connecting shaft 18, and the rotating roller 19 is in contact with the extrusion block 16. The extrusion block 16 extrudes the rotating roller 19, driving the rotating roller 19 to move. The rotating roller 19 drives the side plate 20 and the connecting shaft 18 to rotate. The connecting shaft 18 drives the rotating plate 2 to rotate, thereby opening the clamping head 3. The rotating roller 19 and the side plate 20 are rotatably connected. When the extrusion block 16 extrudes the rotating roller 19, the friction between the two can be reduced, thereby improving the convenience of operation.
[0056] In a further optimized solution, a protrusion 17 is provided on one side of the extrusion block 16 away from the moving block 11, and the rotating roller 19 contacts the protrusion 17. Both upper and lower sides of the protrusion 17 are arc-shaped, so that the rotating roller 19 moves more smoothly.
[0057] Further optimized solution, the end of the side plate 20 is rotatably connected with a connecting column 21, the connecting column 21 is coaxially arranged with the connecting shaft 18, and a torsion spring 22 is sleeved on the outside of the connecting column 21, one end of the torsion spring 22 is fixedly connected to the side plate 20, and the other end of the torsion spring 22 is fixedly connected to the inner wall of the housing 1. The setting of the torsion spring 22 facilitates the reset of the connecting shaft 18. When the wire is located between the two clamps 3, the sliding handle 6 is released, and the connecting shaft 18 is driven to rotate in the opposite direction under the action of the torsion spring 22, thereby driving the side plate 20 and the rotating roller 19 to rotate, and the rotating roller 19 squeezes the protrusion 17 to drive the squeezing block 16 to move in the opposite direction, and the squeezing block 16 drives the moving block 11 and the sliding handle 6 to move in the opposite direction, thereby resetting the moving block 11.
[0058] Further optimization scheme, fixed plates 14 are respectively provided at both ends of the extrusion block 16, and the fixed plates 14 are fixedly connected to the housing 1 by screws, and a clearance groove 26 is provided in the fixed plate 14, and a roller 25 is rotatably connected in the clearance groove 26, and a moving rod 23 is rotatably connected to the side wall of the roller 25, and the end of the moving rod 23 away from the roller 25 is fixedly connected to the extrusion block 16, and a sliding groove 24 is provided on the side wall of the fixed plate 14, and the moving rod 23 is adapted to the sliding groove 24. When the extrusion block 16 moves, it drives the moving rod 23 to move along the sliding groove 24, and at the same time drives the roller 25 to roll in the clearance groove 26. The setting of the roller 25 improves the mobility performance, making the whole process run more smoothly.
[0059] In a further optimized solution, a pair of vertical rods 12 are fixedly connected in the housing 1, and the vertical rods 12 penetrate the moving block 11 and are slidably connected to the moving block 11. The vertical rods 12 are provided to limit the moving block 11, ensuring that it moves stably in the vertical direction.
[0060] In a further optimized solution, connecting blocks 13 are fixedly connected to both sides of the moving block 11, the connecting blocks 13 extend out of the housing 1 and are fixedly connected to the sliding handle 6, the outer side of the housing 1 is symmetrically provided with grooves 5, the sliding handle 6 is located in the grooves 5 and is slidably connected to the grooves 5. The connecting blocks 13 are used to connect the sliding handle 6 and the moving block 11, and play a bearing role.
[0061] For a further optimized solution, the locking member includes a fixing block 8 fixed on the top surface of the chuck 3. A dovetail groove 9 is formed on the fixing block 8. The two fixing blocks 8 are connected by a connecting plate 7. Symmetrically fixed to the bottom surface of the connecting plate 7 are sliding blocks 10, and the sliding blocks 10 are adapted to the dovetail grooves 9. When not in use, the distance between the two dovetail grooves 9 is greater than the distance between the two sliding blocks 10. After the two chucks 3 clamp the wire, force the two chucks 3 together, so that the two sliding blocks 10 are inserted into the two dovetail grooves 9, and then move the connecting plate 7 to make the sliding blocks 10 completely inserted into the dovetail grooves 9, thereby enabling the chuck 3 to clamp the wire more stably.
[0062] Furthermore, several stripes are provided on the inner side of the chuck 3. The provision of the stripes can increase the friction between the chuck 3 and the wire member, thereby enhancing the clamping stability.
[0063] A method for using a grounding wire clamp includes the following steps:
[0064] The staff climbs to the designated position on the pole through tools and wears the corresponding protective tools to ensure that the hand can touch the wire;
[0065] Move the sliding handle 6 to make the control and adjustment mechanism operate. The control mechanism drives the two rotating plates 2 and the two chucks 3 to rotate in opposite directions. At this time, the two chucks 3 open;
[0066] Hold the device and move it below the wire, and make the wire located between the two chucks 3. At this time, release the sliding handle 6, and the adjustment mechanism operates in the reverse direction. At this time, the two chucks 3 are buckled on the wire;
[0067] Further lock the two chucks 3 through the locking member to prevent loosening;
[0068] Connect the grounding rod to the suspension bracket 4, and connect the wire body on the grounding rod to the grounding electrode on the ground to complete the installation.
[0069] Embodiment 2
[0070] Refer to Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the locking member includes a strip-shaped block 27 fixed on the top surface of the chuck 3. The screw 28 sequentially passes through the two strip-shaped blocks 27 and is threadedly connected to the strip-shaped blocks 27. The end of the screw 28 is locked by a nut 29. After the chuck 3 clamps the wire, rotate the screw 28 to make the two strip-shaped blocks 27 move towards each other, thereby further fastening the chuck 3 to improve stability; the end of the screw 28 is fixed by a double nut 29 to prevent the screw 28 from loosening due to shaking or other factors.
[0071] Embodiment 3
[0072] Refer to Figure 9As shown, the difference between this embodiment and Embodiment 1 is that the connection between the suspension bracket 4 and the grounding rod is replaced by a special-shaped rod 30 instead of the original straight rod. The straight rod is clamped by two clamping rods on the grounding rod. When there is an irresistible shaking, the grounding rod will displace or even fall off on the straight rod, affecting the safety of the staff. After replacing it with the special-shaped rod 30, the clamping between the clamping rod and the special-shaped rod 30 is more stable and will not slip, greatly improving the safety performance.
[0073] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.
