Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electric power fittings, in particular to a high-voltage electric power fitting for electric power lines. Background Art

[0002] High-voltage power fittings are mainly used to connect, fix and insulate the conductors of high-voltage power lines to ensure the safe operation of the power system. High-voltage power fittings connect high-voltage conductors through bolts, fasteners, etc. to ensure that the electrical connection between the conductors is stable and reliable to transmit high-voltage electricity. Spacers are a type of high-voltage power fittings, which are insulating rod-shaped devices installed on high-voltage power lines. High-voltage power fittings spacers are usually made of insulating materials, which can effectively provide electrical isolation between conductors, prevent current from being conducted through the contact points between fittings, and ensure the safe operation of the power system.

[0003] High-voltage electric fittings spacers can be used as fixed points to support conductors, helping to maintain the position and tension of the conductors stable. High-voltage electric fittings spacers are usually installed in areas where conductors span longer distances or require additional support to prevent the conductors from sagging or vibrating. Different types of conductors are installed at different intervals, causing the conductors to be subjected to different mechanical and electrical stresses during operation. After the high-voltage electric fittings spacers are produced, their sizes are generally fixed, and it is difficult to adjust the spacing. Therefore, it is necessary to select high-voltage electric fittings spacers of different sizes according to the specific conditions of the conductors, making it difficult for high-voltage electric fittings spacers to adapt to different types of conductors. Therefore, we propose a high-voltage electric fitting for power lines. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5The utility model provides a technical solution: a high-voltage power hardware for power lines, including a high-voltage hardware spacer plate 1 and a gear ring 2, the interior of the high-voltage hardware spacer plate 1 is movably connected to the gear ring 2 through a bearing, and the gear ring 2 is connected to a toothed disc 201, a knob 2011 is fixed to one side of the toothed disc 201, the toothed disc 201 is movably connected to the high-voltage hardware spacer plate 1 through a bearing, and a first bevel gear 202 is fixed to one side of the toothed disc 201, the first bevel gear 202 is connected to a second bevel gear 203, and the first bevel gear 202 and the second bevel gear 203 are respectively movably connected to the high-voltage hardware spacer plate 1 through bearings, a screw 204 is fixed to one side of the second bevel gear 203, and the screw 204 is connected to the high-voltage hardware spacer plate through a bearing. 1 is movably connected, and the screw rod 204 is connected to the butt tube 205. A slider 206 is fixed to one side of the butt tube 205. A slide groove 207 is provided on the side of the high-voltage hardware spacer plate 1 close to the slider 206. The slider 206 and the slide groove 207 are slidably connected. A fixed clamping plate 208 is fixed to one end of the butt tube 205, and the fixed clamping plate 208 is movably connected to the connecting clamping plate 209 through a rotating shaft. The gear ring 2 is meshed with the gear disc 201, the first bevel gear 202 is meshed with the second bevel gear 203, the screw rod 204 is threadedly connected to the butt tube 205, the cross-sectional size of the slider 206 matches the cross-sectional size of the slide groove 207, and insulating rubber pads are respectively fixed to the inner side of the fixed clamping plate 208 and the inner side of the connecting clamping plate 209.

[0024] In specific implementation, according to Figures 1 - 5 , high-voltage power fittings spacer bars can be used as fixed points to support the conductors, helping to maintain the position and tension of the conductors stable. High-voltage power fittings spacer bars are usually installed in areas where the conductors span a long distance or require additional support to prevent the conductors from sagging or vibrating. When the spacer bars of high-voltage power fittings are installed with conductors of different sizes, a plum screwdriver can be used to rotate the knob 2011, so that the knob 2011 drives the toothed disc 201 to rotate, and the toothed ring 2 is meshed with the toothed disc 201, so that each toothed ring 2 rotates at the same time, so that the toothed ring 2 can drive each first bevel gear 202 to rotate, and then the first bevel gear 202 is meshed with the second bevel gear 203 to make the first bevel gear 202 rotate. The first bevel gear 202 can drive the second bevel gear 203 to rotate, and the second bevel gear 203 drives the screw 204 to rotate. The cross-sectional size of the slider 206 is matched with the cross-sectional size of the slide groove 207, so that the slider 206 can limit the butt joint 205 to rotate with the screw 204, and then the screw 204 is threadedly connected to the butt joint 205, so that the butt joint 205 can drive the slider 206 to slide along the slide groove 207, so that each butt joint 205 can move away from or approach each other, so that the butt joint 205 adjusts the distance between each fixing clamp 208 and the connecting clamp 209, so that the spacer rods of the high-voltage power hardware can adapt to wires with different spacings.

[0025] Please refer to Figures 1 - 3 On one side of the docking pipe 205 close to the fixed clamping plate 208, a docking groove 3 is opened. One end of the connecting clamping plate 209 slides through a bolt 301. One end of the bolt 301 is docked with the docking groove 3. And on the side of the bolt 301 close to the docking groove 3, a first magnetic ring 302 is inlaid. On the side of the connecting clamping plate 209 close to the bolt 301, a second magnetic ring 303 is inlaid. And on the end of the bolt 301 close to the second magnetic ring 303, a connecting spring 304 is sleeved. The two ends of the connecting spring 304 are respectively fixed to the connecting clamping plate 209 and the connecting ring plate 305. And the connecting ring plate 305 is movably connected to the bolt 301 through a bearing. The docking groove 3 is in threaded connection with the bolt 301. The inner spacing of the second magnetic ring 303 matches the diameter of the first magnetic ring 302. The first magnetic ring 302 and the second magnetic ring 303 are magnetically attracted to each other.

[0026] During specific implementation, according to Figures 1 - 3 When the spacer of the high-voltage electrical fitting is installed on the conductor, rotate the bolt 301. Due to the threaded connection between the docking groove 3 and the bolt 301, the bolt 301 is disengaged from the docking groove 3. At this time, pull the bolt 301 outwards to extend the connecting spring 304, and make the second magnetic ring 303 fit with the first magnetic ring 302. Through the magnetic attraction between the first magnetic ring 302 and the second magnetic ring 303, the first magnetic ring 302 and the second magnetic ring 303 are restricted together, so that the bolt 301 is restricted on one side of the connecting clamping plate 209, making it difficult for the bolt 301 to disengage from the connecting clamping plate 209. At this time, rotate the connecting clamping plate 209, and then place the fixed clamping plate 208 and the connecting clamping plate 209 on the outside of the conductor. Push the bolt 301 again to rotate and dock the bolt 301 with the docking groove 3, so that the bolt 301 and the docking groove 3 are restricted together. At this time, the connecting spring 304 has a force to contract inwards, which can prevent loosening between the bolt 301 and the docking groove 3, and restrict the conductor between the fixed clamping plate 208 and the connecting clamping plate 209, making it convenient to restrict the spacer of the high-voltage electrical fitting to the conductor.

[0027] In summary, the spacer of high-voltage electrical fittings can serve as a fixed point for supporting the conductor, helping to maintain the position and tension stability of the conductor to prevent the conductor from sagging or vibrating. When the spacer of high-voltage electrical fittings is installed with conductors of different sizes, rotate the knob 2011 to make each docking tube 205 move away from or close to each other, so that the docking tube 205 adjusts the distance between each fixed clamping plate 208 and the connecting clamping plate 209, enabling the spacer of high-voltage electrical fittings to adapt to conductors with different spacings. When the spacer of high-voltage electrical fittings is installed with the conductor, rotate and pull the bolt 301 to make the bolt 301 restricted on one side of the connecting clamping plate 209, making it difficult for the bolt 301 to disengage from the connecting clamping plate 209. Then place the fixed clamping plate 208 and the connecting clamping plate 209 on the outside of the conductor, restricting the conductor between the fixed clamping plate 208 and the connecting clamping plate 209, making it convenient for the spacer of high-voltage electrical fittings to be restricted together with the conductor. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
