Technical Field
[0001] This invention relates to the field of grounding equipment technology, specifically a grounding device for overhead line maintenance. Background Technology
[0002] Currently, during power outage maintenance of overhead power lines in the power distribution network, the short-circuit grounding device used consists of an insulated operating rod, a hook, and a grounding copper wire. The insulated rod and hook are fixed together, and the grounding copper wire is connected to the end of the hook with screws. During line maintenance, the hook is hung on the overhead line, and the operating rod and grounding copper wire are pressed tightly against the ground and perpendicular to it under the action of gravity.
[0003] In existing grounding systems, the grounding wire is typically suspended directly and exposed between the overhead line and the grounding pole. This lower section of the grounding wire, close to the ground, lacks necessary protective measures. When vehicles or pedestrians move near the grounding wire, foreign objects can easily come into contact with or even become stuck on it, dragging it along. In severe cases, this can even cause the grounding wire to fall off the surface of the overhead line. Furthermore, existing grounding wires are simply coiled and wound, making it difficult to easily adjust their length, resulting in poor performance. Summary of the Invention
[0004] The purpose of this invention is to provide a grounding device for overhead line maintenance, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A grounding device for overhead line maintenance includes a base and a grounding wire. A grounding conductive rod is fixedly installed on the surface of the base. The bottom end of the grounding wire is connected to the grounding conductive rod, and a hook is connected to the top end of the grounding wire. An insulated control rod is rotatably installed on the surface of the hook. A protective mechanism that cooperates with the grounding wire is provided on the surface of the base. The protective mechanism includes a protective sleeve and a positioning component. Multiple sets of protective sleeves are provided and are sequentially nested from the outside to the inside. The bottom end of the outermost protective sleeve is fixedly installed on the surface of the base. The positioning component is located between two adjacent sets of protective sleeves and is used to adjust the relative positions of the multiple sets of protective sleeves. A control mechanism is provided on the surface of the grounding wire. The control mechanism includes a winding component and an adjusting component. The winding component is located on the surface of the grounding wire, and the adjusting component is connected to the winding component. The adjusting component is used to adjust the length of the grounding wire by cooperating with the winding component.
[0006] As a further aspect of the present invention: the positioning component includes multiple sets of vertical grooves opened on the inner sidewall of the protective cylinder, a horizontal groove opened on the inner sidewall of the protective cylinder, the horizontal groove being connected to the top of the vertical groove, a locking groove opened on the inner sidewall of the protective cylinder, the locking groove being connected to the end of the horizontal groove away from the vertical groove, and a locking block that cooperates with the locking groove is fixedly installed at the bottom end of the outer sidewall of the protective cylinder, and the vertical groove and the horizontal groove are respectively slidably engaged with the locking block.
[0007] As a further embodiment of the present invention: the winding assembly includes a storage box, a winding roller is rotatably mounted inside the storage box, a top hole is opened on the top wall of the storage box, a bottom hole is opened on the bottom wall of the storage box, a fixing hole is opened on the surface of the winding roller, one end of the winding roller extends to the outside of the storage box and is fixedly mounted on a positioning plate, and the grounding wire passes through the bottom hole, the fixing hole and the top hole in sequence from bottom to top, with the middle part of the grounding wire fixedly installed in the fixing hole.
[0008] As a further aspect of the present invention: the adjustment component includes a telescopic groove located outside the positioning plate and opened on the side wall of the storage box; a sliding block is slidably installed in the telescopic groove; a compression spring is fixedly installed at the end of the telescopic groove away from the positioning plate; the telescopic end of the compression spring is connected to the sliding block; multiple sets of equally spaced limiting holes are opened on the annular side wall of the positioning plate; one end of the sliding block extends to the outside of the telescopic groove and is fixedly installed with a limiting rod that cooperates with the limiting hole; a locking element is provided on the surface of the sliding block; the locking element is used to adjust the position of the sliding block within the telescopic groove.
[0009] As a further aspect of the present invention: the locking member includes a side hole located outside the telescopic groove on the surface of the storage box, and an L-shaped rod that cooperates with the side hole is rotatably mounted on the surface of the sliding block.
[0010] As a further aspect of the present invention: a positioning ring is fixedly installed on the surface of the base, the inner side of the positioning ring is provided with an internal thread, and the bottom wall of the outermost protective sleeve is provided with an external thread that cooperates with the internal thread.
[0011] As a further embodiment of the present invention: the snap-fit block is made of magnetic material, and magnetic positioning pieces that cooperate with the snap-fit block are fixedly installed at the bottom end of the vertical groove and the bottom end of the snap-fit slot, respectively.
[0012] Compared with the prior art, the beneficial effects of the present invention are: by setting the positioning component and the protective sleeve to cooperate with each other, the relative position of multiple sets of protective sleeves and the grounding wire can be conveniently adjusted on the outside of the grounding wire. Multiple sets of protective sleeves can provide all-round protection for the grounding wire, effectively improving the stability of the grounding wire during use. It solves the problem that foreign objects from the outside can easily come into contact with or even get stuck on the grounding wire, thus dragging the grounding wire and moving it. In severe cases, it can even directly cause the grounding wire to fall off the surface of the overhead line.
[0013] By setting up a winding component and an adjustment component to work together, the grounding wire can be easily wound up and unwound, making it convenient to store and store. This solves the problem that existing grounding wires are simply wound up and twisted, making it difficult to adjust the length of the grounding wire and resulting in poor performance.

Detailed Implementation
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.
[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0024] like Figure 1 , Figure 2 , Figure 3 The diagram shows a structural representation of a grounding device for overhead line maintenance according to an embodiment of the present invention. It includes a base 1 and a grounding wire 2. A grounding conductive rod 3 is fixedly mounted on the surface of the base 1. The bottom end of the grounding wire 2 is connected to the grounding conductive rod 3. A hook 4 is connected to the top end of the grounding wire 2. An insulated control rod 5 is rotatably mounted on the surface of the hook 4. A protective mechanism 6, which cooperates with the grounding wire 2, is provided on the surface of the base 1. The protective mechanism 6 includes a protective sleeve 61 and a positioning component 62. Multiple sets of protective sleeves 61 are provided, arranged from the outside inwards. The outermost protective sleeve 61 is detachably mounted on the surface of the base 1. The positioning component 62 is located between two adjacent sets of protective sleeves 61. The positioning component 62 is used to adjust the relative positions of multiple sets of protective sleeves 61. The surface of the grounding wire 2 is provided with a control mechanism 7. The control mechanism 7 includes a winding component 71 and an adjusting component 72. The winding component 71 is located on the surface of the grounding wire 2. The adjusting component 72 is connected to the winding component 71. The adjusting component 72 is used to adjust the length of the grounding wire 2 by cooperating with the winding component 71.
[0025] Initially, the winding assembly 71 stores the grounding wire 2. During use, the grounding wire 2 is passed through multiple sets of protective sleeves 61, with the bottom end connected to the grounding conductive rod 3 and the top end connected to the hook 4. The adjusting assembly 72 works in conjunction with the winding assembly 71 to easily unwind the grounding wire 2 and adjust its length. The operator uses the insulated control rod 5 to install the hook 4 on the overhead line. During use, the positioning assembly 62 can easily adjust the position of the multiple sets of protective sleeves 61, controlling them to move vertically upwards sequentially from the inside out. The multiple sets of protective sleeves 61 provide comprehensive protection for the lower portion of the grounding wire 2, effectively preventing external objects from contacting or jamming the grounding wire and dragging it. After use, the winding assembly and adjusting assembly 72 work together to easily organize the grounding wire 2. The positioning assembly 62 controls the multiple sets of protective sleeves 61 to move downwards and to be fitted together from the outside in.
[0026] like Figure 2 , Figure 4 , Figure 7As shown, in a preferred embodiment of the present invention, the positioning component 62 includes multiple sets of vertical grooves 622 opened on the inner sidewall of the protective sleeve 61, a horizontal groove 623 opened on the inner sidewall of the protective sleeve 61, the horizontal groove 623 being connected to the top of the vertical grooves 622, a locking groove 624 opened on the inner sidewall of the protective sleeve 61, the locking groove 624 being connected to the end of the horizontal groove 623 away from the vertical groove 622, and a locking block 621 that cooperates with the locking groove 624 is fixedly installed at the bottom of the outer sidewall of the protective sleeve 61, and the vertical grooves 622 and the horizontal grooves 623 are respectively slidably engaged with the locking block 621.
[0027] Initially, the locking block 621 on the surface of the inner casing 61 is at the bottom of the vertical groove 622 of the outer casing 61, and multiple casings 61 are sequentially fitted together from the outside to the inside. When protection of the grounding wire 2 is required, the worker holds the innermost casing 61 and moves it upward. The casing 61 drives the locking block 621 to move upward synchronously within the vertical groove 622. As it continues to move upward, multiple casings 61 can move upward sequentially from the inside to the outside. After the locking block 621 moves to the top of the vertical groove 622, the worker holds the protective sleeve 61 and rotates it. The protective sleeve 61 moves the locking block 621 from the top of the vertical groove 622 towards the horizontal groove 623. When the locking block 621 moves to the end of the horizontal groove 623 away from the vertical groove 622, the worker releases the protective sleeve 61. The protective sleeve 61 moves the locking block 621 downward into the locking slot 624. The locking slot 624 and the locking block 621 cooperate to support and position multiple sets of protective sleeves 61. At this time, multiple sets of protective sleeves 61 can provide all-round protection for the grounding wire 2. After the maintenance is completed, the worker holds the innermost protective sleeve 61 and moves it upward, thereby moving the locking block 621 into the horizontal groove 623. The worker then rotates the protective sleeve 61 in the opposite direction to control the locking block 621 to move into the vertical groove 622. The snap-fit block 621 moves downward within the vertical groove 622, which can conveniently control the overall connection of multiple sets of protective sleeves 61 from the outside to the inside.
[0028] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, in a preferred embodiment of the present invention, the winding assembly 71 includes a storage box 711, a winding roller 712 is rotatably mounted inside the storage box 711, a top hole 713 is provided on the top wall of the storage box 711, a bottom hole 714 is provided on the bottom wall of the storage box 711, a fixing hole 715 is provided on the surface of the winding roller 712, one end of the winding roller 712 extends to the outside of the storage box 711 and is fixedly mounted on a positioning plate 716, and the grounding wire 2 passes through the bottom hole 714, the fixing hole 715 and the top hole 713 from bottom to top, and the middle part of the grounding wire 2 is fixedly installed in the fixing hole 715.
[0029] The take-up roller 712 and the storage box 711 are installed on the outside of the grounding wire 2. Initially, the grounding wire 2 is wound up entirely on the surface of the take-up roller 712 and inside the storage box 711. The top end of the grounding wire 2 is outside the top hole 713, and the bottom end is outside the bottom hole 714. At this time, the adjusting component 72 fixes the position of the positioning plate 716 on the outside of the storage box 711. When the grounding wire 2 needs to be used, the adjusting component 72 releases the restriction on the positioning plate 716 on the outside of the storage box 711. At this time, the take-up roller 712 can rotate freely inside the storage box 711. The operator can easily pull out the top and bottom ends of the grounding wire 2 from the top hole 713 and the bottom hole 714 respectively, and connect the grounding wire 2 to the grounding conductive rod 3 and the hook 4 for grounding protection. After use, rotate the positioning disc 716 by hand. The positioning disc 716 drives the winding roller 712 to rotate. The winding roller 712 winds up the grounding wire 2, which can then be conveniently wound into the storage box 711.
[0030] like Figure 1 , Figure 5 , Figure 6 As shown, in a preferred embodiment of the present invention, the adjustment component 72 includes a telescopic groove 721 located outside the positioning disk 716 and opened on the side wall of the storage box 711. A sliding block 722 is slidably installed in the telescopic groove 721. A compression spring 723 is fixedly installed at one end of the telescopic groove 721 away from the positioning disk 716. The telescopic end of the compression spring 723 is connected to the sliding block 722. A plurality of equally spaced limiting holes 725 are opened on the annular side wall of the positioning disk 716. One end of the sliding block 722 extends to the outside of the telescopic groove 721 and is fixedly installed with a limiting rod 724 that cooperates with the limiting hole 725. A locking member 8 is provided on the surface of the sliding block 722. The locking member 8 is used to adjust the position of the sliding block 722 in the telescopic groove 721.
[0031] Initially, the compression spring 723 applies a pushing force to the sliding block 722, and the limiting rod 724 on the surface of the sliding block 722 inserts into the limiting hole 725 on the surface of the positioning plate 716. At this time, the positioning plate 716 is fixed on the outside of the storage box 711. When it is necessary to retract or extend the grounding wire 2, the sliding block 722 is pushed to move within the telescopic groove 721, thereby separating the limiting rod 724 from the limiting hole 725. At this time, the positioning plate 716 can rotate freely on the outside of the storage box 711. The positioning plate 716 controls the winding roller 712 to rotate synchronously within the storage box 711 to retract or extend the grounding wire 2. After the grounding wire 2 has moved to the appropriate position, the locking member 8 releases the restriction on the sliding block 722, and the limiting rod 724 on the surface of the sliding block 722 is inserted into the limiting hole 725 on the surface of the positioning plate 716 again, which can fix the position of the positioning plate 716 and the winding roller 712 again.
[0032] like Figure 5 As shown, in a preferred embodiment of the present invention, the locking member 8 includes a side hole 81 located outside the telescopic groove 721 on the surface of the storage box 711, and an L-shaped rod 82 that cooperates with the side hole 81 is rotatably mounted on the surface of the sliding block 722.
[0033] When the sliding block 722 is pushed to move within the telescopic groove 721, causing the limiting rod 724 to separate from the limiting hole 725, the L-shaped rod 82 is rotated and inserted into the side hole 81. The L-shaped rod 82 and the side hole 81 cooperate with each other, and the position of the sliding block 722 can be fixed within the telescopic groove 721.
[0034] like Figure 3 , Figure 7 As shown, in a preferred embodiment of the present invention, a positioning ring 9 is fixedly installed on the surface of the base 1. The positioning ring 9 has an internal thread on its inner side, and the bottom wall of the outermost protective sleeve 61 has an external thread that mates with the internal thread. Through the interaction of the internal and external threads, multiple sets of protective sleeves 61 can be easily installed and removed on the surface of the base 1.
[0035] In a preferred embodiment of the present invention, the snap-fit block 621 is made of magnetic material, and magnetic positioning pieces that cooperate with the snap-fit block 621 are fixedly installed at the bottom end of the vertical groove 622 and the bottom end of the slot 624, respectively.
[0036] The working principle of this invention is as follows: Initially, the snap-fit block 621 on the surface of the inner protective sleeve 61 is at the bottom end of the vertical groove 622 of the outer protective sleeve 61. At this time, multiple sets of protective sleeves 61 are sequentially sleeved from the outside to the inside. The grounding wire 2 is wound up on the surface of the take-up roller 712 and is located inside the storage box 711. The top end of the grounding wire 2 is outside the top hole 713, and the bottom end of the grounding wire 2 is outside the bottom hole 714. When the grounding wire 2 needs to be used, the sliding block 722 is pushed to move in the telescopic groove 721, thereby causing the limiting rod 724 to separate from the limiting hole 725. At this time, the positioning plate 716 can rotate freely outside the storage box 711. The positioning plate 716 controls the take-up roller 712 to rotate synchronously inside the storage box 711. The operator can easily pull out the top and bottom ends of the grounding wire 2 from the top hole 713 and the bottom hole 714 respectively, and connect the grounding wire 2 to the grounding conductive rod 3 and the hook 4 for grounding protection. The staff member used an insulated control rod 5 to install the hook 4 on the overhead line.
[0037] During use, the operator holds the innermost protective sleeve 61 and moves it upwards. The sleeve 61 drives the locking block 621 to move upwards synchronously within the vertical groove 622. This upward movement continues, and multiple sleeves 61 can be moved sequentially from the inside out. Once the locking block 621 reaches the top of the vertical groove 622, the operator rotates the sleeve 61, causing it to move from the top of the vertical groove 622 towards the horizontal groove 623. When the locking block 621 reaches the end of the horizontal groove 623 furthest from the vertical groove 622, the operator releases the sleeve 61. The sleeve 61 then drives the locking block 621 downwards into the locking slot 624. The locking slot 624 and the locking block 621 work together to support and position multiple sleeves 61. At this point, multiple sleeves 61 provide comprehensive protection for the grounding wire 2. After maintenance, the worker holds the innermost protective sleeve 61 and moves it upward, thereby moving the locking block 621 into the horizontal groove 623. The worker then rotates the protective sleeve 61 in the opposite direction, controlling the locking block 621 to move into the vertical groove 622. The locking block 621 moves downward in the vertical groove 622, allowing for convenient control of multiple sets of protective sleeves 61 to be fitted together from the outside in. The worker then rotates the positioning disc 716, which drives the winding roller 712 to rotate, thereby conveniently winding the grounding wire 2 into the storage box 711.
[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
