[0001] This utility model relates to the field of power distribution equipment maintenance technology, and in particular to a safe operation and maintenance device for power distribution equipment. Background Technology

[0002] The power distribution equipment safety operation and maintenance device is a complete set of equipment / tools used for power isolation, voltage testing and grounding, physical protection, prevention of misoperation, and insulated work. Its core objective is to prevent electric shock, arc burns, and accidental closing. It follows a standard procedure of power outage – voltage testing – tagging and locking – grounding wire installation – barrier installation (power outage, testing, padding, and barrier connection), while simultaneously meeting the requirements of double insulation, mechanical / electrical interlocking, and withstands rated voltage and short-circuit current. In the power distribution equipment safety operation and maintenance device, the insulated operating rod is used for opening and closing operations.

[0003] However, existing insulated operating rods are often inconvenient for installing, disassembling, and replacing the switch hook, and the angle of the switch hook cannot be adjusted, resulting in poor applicability.

[0004] Therefore, it is necessary to provide a device for safe operation and maintenance of power distribution equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problems of existing power distribution equipment safety operation and maintenance devices being inconvenient for installing, disassembling, and replacing switch hooks, unable to adjust the angle of the switch hooks, and having poor applicability, this utility model provides a power distribution equipment safety operation and maintenance device.

[0006] The power distribution equipment safety operation and maintenance device provided by this utility model includes: a hollow rod; a threaded sleeve slidably installed on the hollow rod; an insulating rod fixedly installed on the top end of the threaded sleeve; a U-shaped plate fixedly installed on the top end of the insulating rod; a positioning plate fixedly installed on the U-shaped plate; a horizontal shaft rotatably installed on the positioning plate; a rotating plate fixedly sleeved on the horizontal shaft; a housing fixedly installed on the rotating plate and having a mounting seat; a pull hook provided on the mounting seat; an installation locking mechanism provided on the housing for installing and locking the pull hook; and an angle adjustment mechanism installed on the U-shaped plate for adjusting the angle of the pull hook.

[0007] Preferably, a plug is fixedly installed at the bottom of the lever hook, and a pin hole is provided on the plug.

[0008] Preferably, the mounting base has a slot that is adapted to the insert block.

[0009] Preferably, the mounting and locking mechanism includes: a bidirectional screw rotatably mounted on the inner wall of the housing; a sliding plate slidably sleeved on the bidirectional screw; a crossbar fixedly mounted on the sliding plate and slidably connected to the housing; a connecting plate fixedly mounted on one end of the crossbar; a pin fixedly mounted on the connecting plate and adapted to the pin hole; a first worm gear rotatably mounted on the inner wall of the housing; a first worm wheel fixedly sleeved on the bidirectional screw and meshing with the first worm gear; and a first knob fixedly mounted on the bottom end of the first worm gear.

[0010] Preferably, the angle adjustment mechanism includes: a second worm gear rotatably mounted on the inner wall of the U-shaped plate; a second worm wheel fixedly sleeved on the horizontal shaft and meshing with the second worm gear; and a second knob fixedly mounted on one end of the second worm gear.

[0011] Preferably, a height adjustment mechanism is provided on the inner wall of the hollow rod, the height adjustment mechanism comprising: a rotating rod rotatably mounted on the inner wall of the hollow rod and extending into the inside of the threaded sleeve; a threaded block fixedly mounted on the top end of the rotating rod and threadedly connected to the inner wall of the threaded sleeve; and a third knob fixedly mounted on the bottom end of the rotating rod.

[0012] Preferably, a groove is formed on the inner wall of the hollow rod, and a slider is fixedly installed on the threaded sleeve, the slider being slidably connected to the inner walls on both sides of the groove.

[0013] Compared with related technologies, the power distribution equipment safety operation and maintenance device provided by this utility model has the following beneficial effects:

[0014] This utility model provides a safe operation and maintenance device for power distribution equipment. It features a switch hook for opening and closing operations, a hollow rod, threaded sleeve, and insulating rod forming a support structure, and a locking mechanism for easy installation, disassembly, and replacement of the switch hook. An angle adjustment mechanism allows for precise alignment of the switch hook with the power distribution switch, adapting to different installation angles. A plug and slot provide initial installation and positioning of the switch hook. A first knob drives a first worm gear to rotate, which in turn drives a first worm wheel to rotate synchronously with a double-ended screw. The double-ended screw drives two sets of sliding plates to move in opposite directions. The sliding plates, via a crossbar, drive a connecting plate and a pin to move synchronously, ensuring the pin accurately enters the pin hole of the plug. The pin insertion limit provides a mechanical lock between the plug and the mounting base, preventing the switch hook from loosening and falling during operation. Reversing the first knob disengages the pin. The pin hole allows for quick disassembly and replacement of the pull hook. The second knob drives the second worm gear inside the U-shaped plate to rotate, which in turn meshes with the second worm wheel, causing the coaxially fixed horizontal shaft to rotate. This horizontal shaft synchronously drives the rotating plate, housing, and the pull hook mounted on it to deflect. The tilt angle of the pull hook can be adjusted as needed to accurately align it with the power distribution switch, adapting to different installation angles. The third knob drives the rotating rod inside the hollow rod to rotate synchronously, causing the threaded block at the top of the rotating rod to rotate accordingly. Because the threaded block is threadedly engaged with the inner wall of the threaded sleeve, and the threaded sleeve is limited by the sliding block and the groove of the hollow rod, its circumferential rotation is restricted. The rotation of the threaded block drives the threaded sleeve to rise and fall smoothly vertically along the hollow rod, simultaneously raising and lowering the upper insulating rod, U-shaped plate, and pull hook as a whole. This adapts to different heights of power distribution maintenance points. The sliding block on the inner wall of the groove guides and limits the extension and retraction of the threaded sleeve.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1-3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the power distribution equipment safety operation and maintenance device provided by this utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A shown in the image; Figure 3 for Figure 1 The enlarged schematic diagram of part B shown in the figure. The power distribution equipment safety operation and maintenance device includes: a hollow rod 1; a threaded sleeve 2 slidably mounted on the hollow rod 1; an insulating rod 3 fixedly mounted on the top end of the threaded sleeve 2; a U-shaped plate 4 fixedly mounted on the top end of the insulating rod 3; a positioning plate 5 fixedly mounted on the U-shaped plate 4; a horizontal shaft 6 rotatably mounted on the positioning plate 5; a rotating plate 7 fixedly sleeved on the horizontal shaft 6; a housing 8 fixedly mounted on the rotating plate 7 and equipped with a mounting base 9; a pull hook 10 provided on the mounting base 9; and a device for... An installation and locking mechanism for installing and locking the switch hook 10; an angle adjustment mechanism installed on the U-shaped plate 4 for adjusting the angle of the switch hook 10. The switch hook 10 can be used for opening and closing operations. The hollow rod 1, threaded sleeve 2 and insulating rod 3 can form a support structure. The installation and locking mechanism facilitates the installation, disassembly and replacement of the switch hook 10. The angle adjustment mechanism can adjust the angle of the switch hook 10 so that the switch hook 10 can be accurately aligned with the power distribution switch and is compatible with working parts with different installation tilt angles.

[0021] The bottom of the pull hook 10 is fixedly installed with a plug 11. The plug 11 has a pin hole 12. The pull hook 10 can be initially installed and positioned by the plug 11 and the slot 13.

[0022] The mounting base 9 has a slot 13, which is adapted to the plug 11. The plug 11 and the slot 13 can be used to initially install and position the lever hook 10.

[0023] The mounting and locking mechanism includes: a bidirectional screw 14 rotatably mounted on the inner wall of the housing 8; a sliding plate 15 slidably sleeved on the bidirectional screw 14; a crossbar 16 fixedly mounted on the sliding plate 15 and slidably connected to the housing 8; a connecting plate 17 fixedly mounted on one end of the crossbar 16; a pin 18 fixedly mounted on the connecting plate 17 and adapted to the pin hole 12; a first worm gear 19 rotatably mounted on the inner wall of the housing 8; a first worm wheel 20 fixedly sleeved on the bidirectional screw 14 and meshing with the first worm gear 19; and a pin 18 fixedly mounted on the bottom of the first worm gear 19. The first knob 21 at the end drives the first worm gear 19 to rotate. The first worm gear 19 meshes with and drives the first worm wheel 20 to rotate synchronously with the double-headed screw 14. The double-headed screw 14 drives the two sets of sliding plates 15 to move in opposite directions. The sliding plates 15 drive the connecting plate 17 and the pin 18 to move synchronously through the crossbar 16, so that the pin 18 accurately enters the pin hole 12 of the plug block 11. The pin insertion limit is used to realize the mechanical locking between the plug block 11 and the mounting base 9, preventing the pull hook 10 from loosening and falling during operation. By turning the first knob 21 in the opposite direction, the pin 18 can be removed from the pin hole 12, and the pull hook 10 can be quickly disassembled and replaced.

[0024] The angle adjustment mechanism includes: a second worm gear 22 rotatably mounted on the inner wall of the U-shaped plate 4; a second worm wheel 23 fixedly sleeved on the horizontal shaft 6 and meshing with the second worm gear 22; and a second knob 24 fixedly mounted on one end of the second worm gear 22. The second knob 24 drives the second worm gear 22 inside the U-shaped plate 4 to rotate, and the second worm gear 22 meshes with the second worm wheel 23, causing the coaxially fixed horizontal shaft 6 to rotate. The horizontal shaft 6 synchronously drives the rotating plate 7, the housing 8, and the switch hook 10 mounted on it to deflect, adjusting the tilt angle of the switch hook 10 as needed so that the switch hook 10 can be accurately aligned with the power distribution switch, adapting to working parts with different installation tilt angles.

[0025] A height adjustment mechanism is provided on the inner wall of the hollow rod 1. The height adjustment mechanism includes: a rotating rod 25 rotatably mounted on the inner wall of the hollow rod 1 and extending into the threaded sleeve 2; a threaded block 26 fixedly mounted on the top of the rotating rod 25 and threadedly connected to the inner wall of the threaded sleeve 2; and a third knob 27 fixedly mounted on the bottom of the rotating rod 25. The third knob 27 drives the rotating rod 25 inside the hollow rod 1 to rotate synchronously, and the threaded block 26 at the top of the rotating rod 25 rotates accordingly. Since the threaded block 26 is threadedly engaged with the inner wall of the threaded sleeve 2, and the threaded sleeve 2 is limited to circumferential rotation by sliding with the sliding groove of the hollow rod 1 through a slider, the rotation of the threaded block 26 can drive the threaded sleeve 2 to rise and fall smoothly vertically along the hollow rod 1, and synchronously drive the upper insulating rod 3, U-shaped plate 4 and switch hook 10 to rise and fall as a whole, so as to adapt to power distribution maintenance points at different heights.

[0026] A groove is provided on the inner wall of the hollow rod 1, and a slider is fixedly installed on the threaded sleeve 2. The slider is slidably connected to the inner walls on both sides of the groove. The extension and retraction of the threaded sleeve 2 can be guided and limited by the slider sliding on the inner wall of the groove.

[0027] The working principle of the power distribution equipment safety operation and maintenance device provided by this utility model is as follows:

[0028] Rotating the third knob 27 causes the rotating rod 25 inside the hollow rod 1 to rotate synchronously. The threaded block 26 at the top of the rotating rod 25 rotates accordingly. Since the threaded block 26 is threadedly engaged with the inner wall of the threaded sleeve 2, and the threaded sleeve 2 is limited to slide through the sliding groove of the hollow rod 1 by the slider, its circumferential rotation is restricted. The rotation of the threaded block 26 can drive the threaded sleeve 2 to rise and fall smoothly vertically along the hollow rod 1, and synchronously drive the upper insulating rod 3, U-shaped plate 4 and switch hook 10 to rise and fall as a whole, so as to adapt to the power distribution maintenance points at different heights.

[0029] Rotate the second knob 24 to drive the second worm gear 22 inside the U-shaped plate 4 to rotate. The second worm gear 22 meshes with the second worm wheel 23, which drives the coaxially fixed horizontal shaft 6 to rotate. The horizontal shaft 6 synchronously drives the rotating plate 7, the housing 8 and the switch hook 10 installed on it to deflect. Adjust the tilt angle of the switch hook 10 as needed so that the switch hook 10 can be accurately aligned with the power distribution switch and adapt to working parts with different installation tilt angles.

[0030] When replacing or assembling the pull hook 10, the locking mechanism enables quick disassembly and reliable fixation. Align the insert 11 at the bottom of the pull hook 10 with the slot 13 on the mounting base 9 and insert it to complete the initial alignment. Then, rotate the first knob 21 to drive the first worm gear 19 to rotate. The first worm gear 19 engages and drives the first worm wheel 20 to rotate synchronously with the double-acting screw 14. The double-acting screw 14 drives the two sets of sliding plates 15 to move in opposite directions. The sliding plates 15 drive the connecting plate 17 and the pin 18 to move synchronously through the crossbar 16, so that the pin 18 accurately enters the pin hole 12 of the insert 11. The pin insertion limit is used to achieve mechanical locking between the insert 11 and the mounting base 9 to prevent the pull hook 10 from loosening and falling during operation. Rotate the first knob 21 in the opposite direction to make the pin 18 exit the pin hole 12, and quickly disassemble and replace the pull hook 10.

[0031] Compared with related technologies, the power distribution equipment safety operation and maintenance device provided by this utility model has the following beneficial effects:

[0032] This utility model provides a safe operation and maintenance device for power distribution equipment. The device allows for opening and closing of the circuit breaker via a pull hook 10. A support structure is formed by a hollow rod 1, a threaded sleeve 2, and an insulating rod 3. A locking mechanism facilitates the installation, disassembly, and replacement of the pull hook 10. An angle adjustment mechanism allows for adjustment of the angle of the pull hook 10, ensuring accurate alignment with the power distribution switch. It is adaptable to working components with different installation angles. The pull hook 10 can be initially installed via a plug 11 and a slot 13. Positioning is achieved by rotating the first worm gear 19 via the first knob 21. The first worm gear 19 meshes with and drives the first worm wheel 20 to rotate synchronously with the double-headed screw 14. The double-headed screw 14 drives the two sets of sliding plates 15 to move in opposite directions. The sliding plates 15 drive the connecting plate 17 and the pin 18 to move synchronously via the crossbar 16, so that the pin 18 accurately enters the pin hole 12 of the insert block 11. The pin insertion limit is used to achieve mechanical locking between the insert block 11 and the mounting base 9, preventing the pull hook 10 from loosening and falling during operation. Turning the first knob 21 in the opposite direction will allow the pin to... 18. Withdraw pin hole 12, quickly disassemble and replace pull hook 10. Drive the second worm 22 inside U-shaped plate 4 to rotate via second knob 24. The second worm 22 meshes with the second worm wheel 23, driving the coaxially fixed horizontal shaft 6 to rotate. The horizontal shaft 6 synchronously drives the rotating plate 7, housing 8 and the pull hook 10 mounted on it to deflect. Adjust the tilt angle of pull hook 10 as needed so that pull hook 10 can be accurately aligned with the power distribution switch. Adapt to working parts with different installation tilt angles. Drive the rotation inside hollow rod 1 via third knob 27. The rod 25 rotates synchronously, and the threaded block 26 at the top of the rotating rod 25 rotates accordingly. Because the threaded block 26 is threadedly engaged with the inner wall of the threaded sleeve 2, and the threaded sleeve 2 is limited to slide by the slider and the groove of the hollow rod 1, its circumferential rotation is restricted. The rotation of the threaded block 26 can drive the threaded sleeve 2 to rise and fall smoothly vertically along the hollow rod 1, and synchronously drive the upper insulating rod 3, U-shaped plate 4 and switch hook 10 to rise and fall as a whole, so as to adapt to the power distribution maintenance points at different heights. The extension and retraction of the threaded sleeve 2 can be guided and limited by the slider sliding on the inner wall of the groove.
