Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire operation, and specifically provides a grounding wire operation device with a hanging function. Background Art

[0002] A grounding wire operation device with a hanging function is a professional device for safety grounding in the power system, mainly used to ensure the safety of staff during the maintenance of high-voltage transmission lines. Through the grounding wire operation device, the grounding wire can be quickly connected to the conductor or wire to form a short-circuit loop, release residual charges, and prevent accidental power-on from causing harm to personnel.

[0003] When grounding high-altitude high-voltage transmission lines, most of the grounding wire operation devices used are drones that drive the grounding clamp and the grounding wire to move upward to be connected to the wire; for wires with many obstacles and relatively low height beside, manual operation of the grounding clamp with a grounding rod is mostly used to hang the grounding wire on the wire, and the length of the grounding rod is increased by installing an extension rod at the lower end of the grounding rod, so as to improve the convenience of grounding wire operation.

[0004] However, the existing grounding wire operation devices are difficult to switch between drone operation and manual operation according to the actual situation, and two grounding wire operation devices are required, resulting in relatively low flexibility and narrow application range in the overall use of the grounding wire operation devices. Summary of the Invention

[0005] In view of the above problems, the embodiments of the present invention provide a grounding wire operation device with a hanging function to solve the technical problems in the related art.

[0006] To achieve the above object, the embodiments of the present invention provide the following technical solutions: A grounding wire operation device with a hanging function includes a grounding rod, a grounding clamp is installed at the top of the grounding rod. The grounding clamp is composed of a wire clamping seat and a wire clamping plate. The wire clamping seat is in a U-shaped structure and the wire clamping plate is slidably installed up and down on the vertical section of the wire clamping seat. The vertical section of the wire clamping seat is connected to the grounding wire, and the grounding wire is connected to the grounding grid or grounding electrode.

Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Refer to Figure 1 、 Figure 2 and Figure 5 , a grounding wire operating device with a hanging function, including a grounding rod 1, a grounding clamp 2 is installed on the top of the grounding rod 1. The grounding clamp 2 is composed of a wire clamping base 20 and a wire clamping plate 21. The wire clamping base 20 is in a U-shaped structure and the wire clamping plate 21 is slidably installed up and down on the vertical section of the wire clamping base 20. The vertical section of the wire clamping base 20 is connected to the grounding wire 3 (refer to Figure 5 ), the grounding wire 3 is connected to the grounding network or grounding electrode. The grounding clamp 2 is hung on the wire, so that the wire, the grounding wire 3, and the grounding network or grounding electrode are connected to form a short-circuit loop, releasing residual charges and preventing accidental power-on from causing harm to personnel.

[0033] Refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6, a connecting rod 22 that slides up and down and is inserted into the grounding rod 1 is installed on the lower end surface of the wire clamping plate 21, and a pushing spring 23 sleeved on the connecting rod 22 is installed between the lower end surface of the wire clamping plate 21 and the wire clamping seat 20; the grounding wire operating device further includes a supplementary rod 4 and a bottom connection mechanism 5 of the machine. A stop bar 10 is installed at the end of the horizontal section on the upper side of the wire clamping seat 20, and the stop bar 10 cooperates with the wire clamping seat 20 so that the horizontal section on the upper side of the wire clamping seat 20 can be hung on the wire.

[0034] Refer to Figure 1 , Figure 4 and Figure 6 , a connection head 6 is fixedly installed on both the top of the supplementary rod 4 and the bottom connection mechanism 5 of the machine. A plug-in locking mechanism 7 is installed at the lower end of the grounding rod 1. The grounding rod 1 is plugged into the connection head 6 on the supplementary rod 4 through the plug-in locking mechanism 7 or plugged into the connection head 6 on the bottom connection mechanism 5 of the machine.

[0035] Refer to Figure 5 and Figure 6 , a first downward driving group 8 is installed on the supplementary rod 4. Before the horizontal section on the upper side of the wire clamping seat 20 is hung on the wire, the connecting rod 22 is moved downward through the first downward driving group 8 to separate the wire clamping seat 20 from the upper horizontal section of the wire clamping plate 21.

[0036] Refer to Figure 4 , Figure 5 and Figure 6 , a second downward driving group 9 is installed on the bottom connection mechanism 5 of the machine, and the second downward driving group 9 has the same function as the first downward driving group 8.

[0037] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , when manually operating, the lower end of the grounding rod 1 is plugged into the connection head 6 on the supplementary rod 4 through the plug-in locking mechanism 7, so as to increase the length of the grounding rod 1, facilitating the manual operation of hanging the grounding wire 3 on the wire; when the grounding rod 1 is plugged into the connection head 6 on the bottom connection mechanism 5 of the machine through the plug-in locking mechanism 7, a drone is used to grab the bottom connection mechanism 5 of the machine to drive the grounding rod 1, the grounding clamp 2 and the grounding wire 3 to move upward to be hung on the wire, facilitating the hanging operation of the wire that is inconvenient to operate at high altitude.

[0038] In summary, the lower end of the grounding rod 1 can be connected to the supplementary rod 4 through the plug-in locking mechanism 7 to adapt to manual hanging operation, or can be connected to the bottom connection mechanism 5 of the machine to adapt to the hanging operation using a drone, avoiding the problem that it is difficult to perform grounding operation on high-altitude wires, having the effect of one machine with two uses, improving the convenience of the hanging operation of the grounding wire 3, and improving the flexibility of the grounding wire operating device, expanding the applicable range of the grounding wire operating device.

[0039] Refer to Figure 1 、 Figure 2 and Figure 3 , the plug-in locking mechanism 7 includes a hollow rod 70 fixedly installed at the lower end of the grounding rod 1. A plurality of wedge-shaped blocks 71 and a plurality of chucks 72 that slide radially along it are sequentially connected to the side wall of the hollow rod 70 from top to bottom. The plurality of chucks 72 and the plurality of wedge-shaped blocks 71 are evenly arranged circumferentially along the hollow rod 70. The chuck 72 is a triangle with an inclined surface facing downwards and a horizontal top. A synchronous connection group that connects the wedge-shaped blocks 71 and the chucks 72 facing each other up and down is installed on the inner wall of the hollow rod 70; the synchronous connection group includes guide rods 73 evenly arranged circumferentially on the inner wall of the hollow rod 70. A connection strip 74 is slidably connected to the guide rod 73. The upper and lower ends of the connection strip 74 are respectively connected to the wedge-shaped block 71 and the chuck 72. A first return spring 75 sleeved on the guide rod 73 is installed between the connection strip 74 and the inner wall of the hollow rod 70. A contraction drive group 76 that pushes the wedge-shaped block 71 and the chuck 72 to move towards the axis of the hollow rod 70 is installed on the grounding rod 1. A balance group 77 is installed between the circumferentially arranged plurality of connection strips 74. A first through hole 78 is opened at the lower end of the hollow rod 70. An insertion block 79 corresponding to the chuck 72 one by one is installed on the side wall of the lower end of the connecting rod 22.

[0040] The contraction drive group 76 is used to, when the plug-in locking mechanism 7 and the connector 6 are disassembled, squeeze the circumferentially arranged plurality of wedge-shaped blocks 71 to move towards the axis direction of the hollow rod 70. The wedge-shaped block 71 drives the connection strip 74 to move, so that the connection strip 74 drives the chuck 72 to move into the hollow rod 70. At this time, the first return spring 75 is in a stretched state. The guide rod 73 horizontally guides the movement of the connection strip 74. The balance group 77 enables the upper and lower ends of the connection strip 74 to move simultaneously, avoiding the deviation of the movement of the connection strip 74. The chuck 72 moves towards the axis of the hollow rod 70 and thus disengages from the connector 6, realizing the detachable connection between the grounding rod 1 and the connector 6, and improving the convenience of the use and operation of the grounding clip 2 and the grounding wire 3 on the grounding rod 1.

[0041] Refer to Figure 1 and Figure 3 , the contraction drive group 76 includes an unlocking sleeve 760 that slides up and down on the grounding rod 1. The upper end of the unlocking sleeve 760 is conical. The inner wall of the lower end of the unlocking sleeve 760 is conical and matches the inclined surface of the wedge-shaped block 71 and has a diameter that gradually decreases upwards. A ball that rolls in contact with the wedge-shaped block 71 is installed on the conical inner wall of the lower end of the unlocking sleeve 760. A compression spring 761 sleeved on the grounding rod 1 is installed between the side wall of the grounding rod 1 and the top of the inner wall of the unlocking sleeve 760.

[0042] Refer to Figure 1 and Figure 3, the balance group 77 includes a barrel sleeve 770 sleeved on the connecting rod 22, and two hinge rods 771 arranged vertically are hinged between the side wall of the barrel sleeve 770 and the connecting bar 74.

[0043] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , when it is necessary to separate the lower end of the grounding rod 1 from the connector 6, manually push the unlocking sleeve 760 downward. The unlocking sleeve 760 squeezes the compression spring 761 to contract, and the tapered inner wall at the lower end of the unlocking sleeve 760 squeezes and pushes the wedge block 71, so that the wedge block 71 moves towards the axis of the hollow rod 70. The balls on the unlocking sleeve 760 roll along the inclined surface of the wedge block 71, and the wedge block 71 synchronously drives the connecting bar 74 to move towards the axis of the hollow rod 70. At the same time, the connecting bar 74 pushes the barrel sleeve 770 to slide upward along the connecting rod 22 through the hinge rod 771 connected to its upper side, and the barrel sleeve 770 drives the lower side of the connecting bar 74 to move through the hinge rod 771 on the lower side, thereby improving the synchronism of the upper and lower sides of the connecting bar 74 and the accuracy and stability of the movement of the chuck 72, until the chuck 72 moves towards the axis of the hollow rod 70 and separates from the connector 6, realizing the disassembly of the grounding rod 1 and the connector 6.

[0044] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the connector 6 includes a connecting seat 60 with a concave vertical cross-section. The top of the connecting seat 60 is provided with alignment guide grooves 61 arranged uniformly along its circumference. The alignment guide grooves 61 correspond to the chucks 72 one by one. The alignment guide grooves 61 are arc-shaped. The lower end of the inner wall of the connecting seat 60 is provided with clamping grooves 62 corresponding to the alignment guide grooves 61 one by one. The lower end of the connecting seat 60 is provided with a second through hole 63 that penetrates up and down.

[0045] When the grounding rod 1 and the connector 6 are inserted and locked, first align the chucks 72 with the alignment guide grooves 61 one by one, and then push the connector 6 or the grounding rod 1 so that the chucks 72 are in contact with the alignment guide grooves 61. Blocked by the alignment guide grooves 61, the chucks 72 will move towards the axis of the hollow rod 70 under the action of resistance until the protruding ends of the chucks 72 are flush with the outer wall of the hollow rod 70. At this time, the first return spring 75 is in a stretched state. The protruding end of the chuck 72 is connected by rolling with a ball. The chuck 72 moves downward along the inner wall of the connecting seat 60 through the ball. When the ball on the chuck 72 is aligned with the clamping groove 62, the chuck 72 enters the clamping groove 62 under the resilience of the first return spring 75, and the top horizontal plane of the chuck 72 abuts against the top of the clamping groove 62, thereby realizing the locking connection between the connector 6 and the grounding rod 1, greatly improving the connection convenience and efficiency between the grounding rod 1 and the connector 6.

[0046] Refer toFigure 1 , Figure 3 , Figure 4 and Figure 5 , the bottom connection mechanism 5 includes a Z-shaped frame 50. The connecting head 6 is fixedly installed at the end of the lower horizontal section of the Z-shaped frame 50. A support member 51 is installed in the middle of the vertical section of the Z-shaped frame 50. When the connecting head 6 at the lower end of the Z-shaped frame 50 is connected to the lower end of the grounding rod 1, the support member 51 is connected to the middle of the grounding rod 1 by bolts. A quadrangular pyramid-shaped hanging through groove 52 is provided on the upper horizontal section of the Z-shaped frame 50, and an entry groove communicating with the hanging through groove 52 is provided on the upper horizontal section of the Z-shaped frame 50. A quadrangular pyramid 53 is hung on the hanging through groove 52. Two hooks 54 are installed at the top of the quadrangular pyramid 53. The entry groove facilitates the two hooks 54 to enter the hanging through groove 52.

[0047] When the bottom connection mechanism 5 is connected to the grounding rod 1, the lower end of the grounding rod 1 is connected to the connecting head 6 on the bottom connection mechanism 5 through the plugging and locking mechanism 7, and then the vertical section of the Z-shaped frame 50 is connected to the middle of the grounding rod 1 through the support member 51, thereby improving the connection stability between the Z-shaped frame 50 and the grounding rod 1. After that, the quadrangular pyramid 53 is pushed into the hanging through groove 52, and the drone grabs the two hooks 54 to lift the Z-shaped frame 50 and the grounding rod 1 upward through the quadrangular pyramid 53 for the operation of hanging the high-altitude wire.

[0048] During the process of pushing the quadrangular pyramid 53 into the hanging through groove 52, the second downward driving group 9 on the bottom connection mechanism 5 drives the connecting rod 22 and the wire clamping plate 21 to move downward and compress the top push spring 23. When the upper horizontal section of the wire clamping seat 20 is hooked on the wire, the up and down movement of the wire clamping seat 20 and the Z-shaped frame 50 is restricted. Then the drone drives the quadrangular pyramid 53 to move downward relatively. At this time, the second downward driving group 9 no longer presses down the connecting rod 22, and the wire clamping plate 21 and the connecting rod 22 move upward under the reset elastic force of the top push spring 23, so that the wire clamping plate 21 and the wire clamping seat 20 clamp the wire, and the drone moves away.

[0049] Refer to Figure 1 , Figure 4 and Figure 5 , the second downward driving group 9 includes an installation groove 90 provided in the vertical section of the Z-shaped frame 50. A swing rod 91 is hinged on the installation groove 90. A guide groove is provided on the side wall of the grounding rod 1 above the support member 51. An inclined rod 92 penetrating the guide groove is installed on the side wall of the connecting rod 22. An L-shaped hook rod 93 is installed at the lower end of the quadrangular pyramid 53. The horizontal section of the L-shaped hook rod 93 is located below the swing rod 91.

[0050] When the connector 6 on the bottom connection mechanism 5 is connected to the grounding rod 1, the end of the swing rod 91 close to the grounding rod 1 enters between the inclined rod 92 and the top of the guiding groove. During the upward movement of the frustum 53 into the hanging through groove 52, the horizontal section of the L-shaped hook rod 93 will push the swing rod 91 to rotate, causing the end of the swing rod 91 inserted into the guiding groove to push the inclined rod 92 downward. The inclined rod 92 drives the connecting rod 22 to move downward synchronously, and the connecting rod 22 drives the wire clamping plate 21 to move downward, increasing the distance between the wire clamping plate 21 and the upper horizontal section of the wire clamping seat 20, facilitating the entry of the wire between them.

[0051] After the horizontal section of the wire clamping seat 20 is hooked on the wire, the drone drives the frustum 53 to move downward. At this time, the horizontal section of the L-shaped hook rod 93 no longer pushes the swing rod 91. At this time, the wire clamping plate 21 moves upward under the restoring force of the top push spring 23 to clamp the wire. At the same time, the connecting rod 22 drives the inclined rod 92 to move upward synchronously with the wire clamping plate 21, and pushes the swing rod 91 to rotate and reset through the inclined rod 92.

[0052] Refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown in

[0053] When the connector 6 on the supplementary rod 4 is connected to the lower end of the grounding rod 1, the chuck 82 at the top of the supplementary rod 80 enters the through hole two 63, and the insert block 79 at the lower end of the connecting rod 22 enters the rectangular groove 83. Then rotate the supplementary rod 80, and the supplementary rod 80 drives the chuck 82 to rotate so that the insert block 79 enters the receiving groove. At this time, the up and down movement of the insert block 79 is restricted. Then pull the supplementary rod 80 to drive the connecting rod 22 to move downward, and then increase the distance between the wire clamping plate 21 and the upper horizontal section of the wire clamping seat 20, facilitating the entry of the wire between them.

[0054] Refer to Figures 1 - 7, Working principle: When manually operating, the lower end of the grounding rod 1 is inserted and locked with the connector 6 on the supplementary rod 4 through the insertion and locking mechanism 7, thereby increasing the length of the grounding rod 1. Then, the connecting rod 22 is driven downward by the first downward driving group 8, so that the distance between the wire clamping plate 21 and the upper horizontal section of the wire clamping seat 20 increases, facilitating the entry of the wire between the two. When the horizontal section of the wire clamping seat 20 is hung on the wire, the pulling of the connecting rod 22 is released, and the wire clamping plate 21 and the connecting rod 22 move upward under the reset elastic force of the pushing spring 23, and the wire clamping plate 21 and the wire clamping seat 20 clamp the wire, thus realizing the wire hanging operation.

[0055] When the grounding rod 1 is inserted and locked with the connector 6 on the bottom machine connection mechanism 5 through the insertion and locking mechanism 7, the bottom machine connection mechanism 5 is grabbed by the unmanned aerial vehicle, and the connecting rod 22 is pushed downward by the second downward driving group 9. The wire clamping plate 21 moves downward synchronously and compresses the pushing spring 23, and then drives the grounding rod 1, the grounding clamp 2 and the grounding wire 3 to move upward to be connected with the wire. After the wire enters between the wire clamping plate 21 and the upper horizontal section of the wire clamping seat 20, the unmanned aerial vehicle drives the quadrangular pyramid platform 53 to move downward. At this time, the second downward driving group 9 no longer presses the connecting rod 22, and the wire clamping plate 21 and the connecting rod 22 move upward under the reset elastic force of the pushing spring 23, so that the wire clamping plate 21 and the wire clamping seat 20 clamp the wire, realizing the wire hanging operation, and then the unmanned aerial vehicle moves away.
