Description

Technical Field

[0001] The invention relates to the technical field of deicing of power transmission lines, in particular to a quick-installed ice-melting short-circuit clamp. Background Art

[0002] The weather is cold in winter, and transmission lines are easily covered with a thick layer of ice. The ice increases the weight of the overhead lines and is prone to resonance under the action of wind, which has a very serious impact on the towers, thus affecting the entire power supply system and posing a threat to our lives and economy.

[0003] In the power system, ice-melting short-circuit wires are a device commonly used to melt ice on transmission lines. For example, DC ice-melting technology mainly melts the ice on the transmission lines by applying DC voltage to the transmission lines and short-circuiting at the ends of the transmission lines to make the conductors heat up. This technology can greatly increase the line current and allow the conductors to heat up themselves. The temperature can reach 10 degrees Celsius during de-icing, and more than 100 kilometers of lines can be quickly melted at a time.

[0004] Patent document number CN202363854U discloses an ice-melting lap wire device, including a lap cable and a lap joint respectively connected to the two ends of the lap cable, the lap joint including an upper clamp block and a lower clamp block that cover each other, one end of the upper clamp block and the lower clamp block are hinged, and upper and lower clamp block locking nuts are provided above the other end of the upper clamp block, and a groove that cooperates with the upper and lower clamp block locking nuts is provided on the top of the upper clamp block, and a swing pull rod is provided below the upper and lower clamp block locking nuts, and the swing pull rod is hinged on the lower clamp block, and a ratchet wrench is installed on the upper ends of the upper and lower clamp block locking nuts, and clamp molds are installed in the middle of the upper clamp block and the lower clamp block.

[0005] The above patent, as the prior art of ice-melting lap clamps, still has the following problems and defects: 1. When installing the ice-melting lap clamps on the conductors, due to the severe icing of the conductors, it is also necessary to remove the ice layer in the installation area of ​​the conductors. Manual removal of the ice layer is laborious and inefficient; 2. According to problem 1, improvements are made by using a thimble in the clamping block of the ice-melting lap clamp to remove the ice layer, but the conductor will be damaged if the force of the thimble is not well controlled; 3. An additional limiting structure needs to be installed to limit the clamping angle of the ice-melting lap clamp on the conductor to adapt to conductors of different sizes, and the operation is complicated; 4. When the upper and lower clamping blocks of the wire clamp are clamped, a certain force needs to be applied, which is inconvenient to apply force during high-altitude operations; 5. After the upper and lower clamping blocks of the wire clamp are clamped, they need to be fixed with bolts, which is inconvenient to install bolts and nuts during high-altitude operations. Summary of the invention

[0006] 1. Technical issues to be resolved

A guide column that cooperates with the keyway of the side gear is provided at the bottom of the adjusting knob, and a circular groove with circumferentially distributed grooves is provided at the bottom of the guide column corresponding to the second pressure block. When the guide column slides into the circular groove, the key on the adjusting knob guide column is stuck in the groove of the corresponding angle, thereby limiting the rotation of the adjusting knob, and also limiting the rotation of the hinged ring. At the same time, the side gear of the small gear cooperates with the shaft end gear of the large gear to improve the adjustment accuracy.

[0028] 3. The quick-installed ice-melting short-circuit clamp can be detachably installed in the pressure rod installation hole by providing a force-applying pressure rod, thereby solving the problem of inconvenient force application during high-altitude operations.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Embodiment 1:

[0052] This embodiment provides a quick-install ice-melting short-circuit clamp having the following technical features.

[0053] See also Figure 1-15A quick-installed ice-melting short-circuit clamp comprises two single-wire clamps 100 for clamping two wires 200 to be short-circuited, the two single-wire clamps 100 are connected by a short-circuit wire 300, and any single-wire clamp 100 comprises a first pressing block 110 and a second pressing block 120 which are connected to each other by rotation up and down, and one side of the first pressing block 110 and the second pressing block 120 are connected to each other by a hinge mechanism 500, and a hinge ring 510 which is relatively stationary with the second pressing block 120 during rotation is connected to the outer side of the hinge mechanism 500, and a limiting protrusion 511 is arranged at a position near the first pressing block 110 on the outer side of the hinge ring 510, and the limiting protrusion 511 comprises a first inclined surface 5111, a second arc surface 5112 and a third limiting block 5113, and an ice-breaking mechanism 600 is arranged in the first pressing block 110, and the ice-breaking mechanism 600 comprises:

[0054] An ice-breaking ejector pin 610, which slides up and down in the first pressing block 110. The bottom end of the ice-breaking ejector pin 610 is used to remove the sharp corner of the ice layer 201 on the wire 200. The tail end of the ice-breaking ejector pin 610 is provided with an ejector pin limiting groove 611;

[0055] A rotating clamping block 620, wherein the rotating clamping block (620) is rotatably connected to the inside of the first pressing block (110), and a limiting end 621 and a force-bearing end 622 are provided on the rotating clamping block 620, and when the limiting end 621 rotates into the ejector pin limiting groove 611, the ice-breaking ejector pin 610 is limited to retract upward;

[0056] The connecting rod 630 slides inside the first pressing block 110. When the hinge mechanism 500 rotates to clamp the wire 200, one end of the connecting rod 630 presses against the top surface of the first inclined surface 5111, the top surface of the second curved surface 5112 and the side surface of the third limiting block 5113 in sequence;

[0057] When one end of the connecting rod 630 close to the hinge ring 510 is pressed against the first inclined surface 5111 at different heights, the connecting rod 630 slides, so that the other end of the connecting rod 630 presses against the force-bearing end 622 to rotate the rotating block 620; when one end of the connecting rod 630 presses against the second curved surface 5112, the connecting rod 630 is stationary; at this time, the other end of the connecting rod 630 presses against the force-bearing end 622 to disengage the limiting end 621 from the ejector limiting groove 611; when one end of the connecting rod 630 presses against the side of the third limiting block 5113, the hinge mechanism 500 is locked.

[0058] Specifically, the bottom of the ejector pin limit groove 611 interferes with the force-bearing end 622. When the rotating block 620 starts to rotate, the force-bearing end 622 first presses the ice-breaking ejector pin 610 downward. When the rotating block 620 rotates a certain angle, that is, when one end of the connecting rod 630 is pressed against the second arc surface 5112, the ice-breaking ejector pin 610 is separated from the force-bearing end 622 and is in a free up and down sliding state to avoid damaging the wire 200.

[0059] Specifically, the lowest point of the first inclined surface 5111 is connected to the outer side of the limiting protrusion 511, and the highest point of the first inclined surface 5111 is connected to the second arc surface 5112. The second arc surface 5112 is an arc with the rotation center of the hinge mechanism 500 as the center. The connecting rod 630 will not rotate when it is pressed on the second arc surface 5112. The third limiting block 5113 is raised relative to the second arc surface 5112. When the connecting rod 630 rotates to the third limiting block 5113, it is stuck, thereby limiting the rotation of the first pressure block 110.

[0060] Specifically, the angle between the two ends of the second curved surface 5112 is proportional to the length of the ice-breaking thimble 610 extending from the bottom of the first pressing block 110. For example, the length of the ice-breaking thimble 610 extending from the bottom of the first pressing block 110 is 2 cm. When the tail of the ice-breaking thimble 610 is released from the limit and the bottom of the ice-breaking thimble 610 is against the wire 200, the hinge mechanism 500 needs to be rotated 5 degrees to retract the ice-breaking thimble 610 into the first pressing block 110. Then, the angle between the two ends of the second curved surface 5112 is 5 degrees. When the length of the ice-breaking thimble 610 extending from the bottom of the first pressing block 110 is greater than 2 cm, the angle between the two ends of the second curved surface 5112 will also be greater than 5 degrees.

[0061] According to the technical scheme, the quick-installed ice-melting short-circuit clamp comprises a first pressing block 110 and a second pressing block 120 which are rotatably connected by a hinge mechanism 500. The first pressing block 110 is provided with an ice-breaking mechanism 600 comprising an ice-breaking pin 610, a rotating block 620 and a connecting rod 630. The hinge mechanism 500 is provided with a hinge ring 510 which is relatively stationary with the second pressing block 120 when in use. The hinge ring 510 is provided with a limiting protrusion 511 comprising a first inclined surface 5111, a second arc surface 5112 and a third limiting block 5113. When the first pressing block 110 rotates relative to the second pressing block 120, when one end of the connecting rod 630 respectively presses against the first inclined surface 5111, the second arc surface 5112 and the third limiting block 5113, the first pressing block 110 rotates relative to the second pressing block 120, and the second arc surface 5112 is provided with a limiting protrusion 5113. When the ice-breaking thimble 610 is pressed against the second curved surface 5112, the ice-breaking thimble 610 is respectively in two states: locked by the limiting end 621 and freely sliding up and down. When one end of the connecting rod 630 is pressed against the side of the third limiting block 5113, the first pressing block 110 is locked at a clamping angle, thereby achieving the removal of the ice layer 201 before the ice-breaking thimble 610 hits the wire 200. When the ice-breaking thimble 610 hits the wire 200, the ice-breaking thimble 610 slides upward to avoid damaging the wire 200. At the same time, the third limiting block 5113 plays a limiting role. There is no need to set and adjust an additional limiting structure to limit the clamping angle of the first pressing block 110 and the second pressing block 120. The operation is simple and convenient, and the installation speed of the wire clamp is improved.

[0062] As an optional embodiment, an articulated shaft 520 is sleeved in the rotating shaft of the articulated mechanism 500, and the articulated shaft 520 and the articulated ring 510 rotate synchronously through the keyway cooperation, and the end of the articulated shaft 520 is fixedly connected to the shaft end gear 530, and the shaft end gear 530 is rotatably connected with the side gear 540, and the number of teeth of the side gear 540 is less than the number of teeth of the shaft end gear 530, and the side gear 540 is installed on the second pressure block 120, and the side gear 540 is connected to the adjusting knob 550, and a guide column is provided on the adjusting knob 550, which slides up and down at the center axis of the side gear 540, and the guide column is fixedly rotatably connected with the side gear 540 through the keyway, and the adjusting knob 550 is in two states of restricted rotation and free rotation when sliding up and down in the rotating shaft of the side gear 540, respectively, so that the adjusting knob 550 is rotated to control the angle of the articulated shaft 520, so as to adapt to wires 200 of different sizes.

[0063] Specifically, the number of teeth on the side gear 540 is smaller than the number of teeth on the shaft end gear 530. Since the angle at which the hinge ring 510 needs to rotate when adjusted is very small, a small gear is required to drive the large gear at the end of the hinge shaft 520. That is, the side gear 540 drives the shaft end gear 530 to rotate, so that when the adjustment knob 550 and the side gear 540 rotate a large angle, the shaft end gear 530, the hinge shaft 520 and the hinge ring 510 rotate a small angle, thereby improving the accuracy of the adjustment.

[0064] As an optional embodiment, a key is provided on the side of the guide post of the adjusting knob 550, a groove is provided on the side of the central axis through hole of the side gear 540 at a position corresponding to the key, a corresponding circular groove is provided in the second pressure block 120 at a bottom position corresponding to the guide post of the adjusting knob 550, and a circumferentially distributed groove is provided on the side of the circular groove. When the adjusting knob 550 is pressed to cause the guide post to slide into the circular groove, the key on the guide post of the adjusting knob 550 is stuck in the groove of the corresponding angle, thereby limiting the rotation of the adjusting knob 550. Due to the transmission connection between the articulated shaft 520 and the adjusting knob 550, the articulated shaft 520 is also restricted from rotating.

[0065] Through the above technical scheme, the quick-installed ice-melting short-circuit clamp is connected by setting a transmission connection between the hinge ring 510, the hinge shaft 520, the shaft end gear 530, the side gear 540 and the adjusting knob 550, so that the angle of the hinge ring 510 can be adjusted by rotating the adjusting knob 550. A guide column matched with the keyway of the side gear 540 is provided at the bottom of the adjusting knob 550, and a circular groove with circumferentially distributed grooves is provided at the bottom of the second pressure block 120 corresponding to the guide column. When the guide column slides into the circular groove, the key on the guide column of the adjusting knob 550 is stuck in the groove of the corresponding angle, thereby limiting the rotation of the adjusting knob 550, and also limiting the rotation of the hinge ring 510. At the same time, the side gear 540 of the small gear cooperates with the shaft end gear 530 of the large gear to improve the adjustment accuracy.

[0066] As an optional embodiment, a cover plate 140 is provided on the top surface of the first pressure block 110, and an ice-breaking ejector pin spring 141 is provided at the top of the ice-breaking ejector pin 610 between the cover plate 140. The ice-breaking ejector pin spring 141 provides a downward force for the ice-breaking ejector pin 610. A rotating coil spring is provided at the rotating connection between the rotating clamping block 620 and the first pressure block 110. The rotating coil spring provides the rotating clamping block 620 with a force to rotate the limiting end 621 into the ejector pin limiting groove 611.

[0067] Specifically, a cover plate 140 is provided on the top surface of the first pressing block 110 to facilitate installation of the ice breaking mechanism.

[0068] Specifically, the ice-breaking ejector spring 141 is at least one of a spring, a hydraulic rod, rubber, silicone, etc.; the rotating coil spring connected to the rotating clamp 620 is a flat scroll spring or a spiral scroll spring, or the rotating clamp 620 is provided with a spring on the side of the limit end 621 away from the ejector limit groove 611, or the rotating clamp 620 is provided with a spring on the side of the force end 622 away from the connecting rod 630.

[0069] As an optional embodiment, the single-wire clamp 100 is provided with two front-to-rear symmetrical rotating bolts 130 on a side away from the hinge mechanism 500. Any rotating bolt 130 includes a bolt rod 131 and a bolt rotating seat 132. The bolt rotating seat 132 is rotatably connected to the first pressure block 110 or the second pressure block 120 on a side away from the hinge mechanism 500. The bolt rod 131 is provided with a thread. When the first pressure block 110 and the second pressure block 120 are clamped, the bolt rod 131 passes through the corresponding holes on the second pressure block 120 or the first pressure block 110 and is fixed by a nut.

[0077] Specifically, the pressure applying rod 400 is not conductive, and the material of the pressure applying rod 400 is rubber.

[0078] Through the above technical solution, the quick-installed ice-melting short-circuit clamp can be detachably installed in the pressure rod installation hole 160 by providing a force-applying pressure rod 400, thereby solving the problem of inconvenient force application during high-altitude operations.

[0079] As an optional embodiment, the first pressing block 110 and the second pressing block 120 are provided with a film sleeve 150 at the position of clamping the conductor 200, and the film sleeve 150 includes a first film sleeve 151 installed on the first pressing block 110 and a second film sleeve 152 installed on the second pressing block 120, and both ends of the first film sleeve 151 and the second film sleeve 152 are provided with end seats 153 for fixing, and the first film sleeve 151 is provided with a film sleeve through hole 1511 for passing the ice-breaking thimble 610.

[0080] Specifically, the first film 151 and the second film 152 are made of copper.

[0081] As an optional embodiment, the short-circuit wire 300 is fixed on the first pressing block 110 or the second pressing block 120 via a wire holder 310 , and the wire holder 310 is electrically connected to at least one of the first film set 151 and the second film set 152 .

[0082] As an optional embodiment, an ice-breaking mechanism 600 including an ice-breaking pin 610, a rotating block 620 and a connecting rod 630 is also provided in the second pressure block 120, a through hole is also provided at a position corresponding to the ice-breaking pin 610 on the second set of membranes 152, and a portion where the hinge mechanism 500 is connected to the first pressure block 110 is also provided with a structure identical to that of the hinge ring 510, so that de-icing can be performed on both sides of the first pressure block 110 and the second pressure block 120 at the same time.

[0083] As an optional embodiment, a protective cover 560 is provided on the second pressing block 120 at the outer side of the corresponding shaft end gear 530 .

[0084] Working principle: when the hinge mechanism 500 rotates, that is, when the angle between the first pressure block 110 and the second pressure block 120 gradually decreases, the end of the connecting rod 630 close to the hinge ring 510 first presses on the hinge ring 510, and at this time, the ice-breaking ejector pin 610 is limited by the tail limit end 621 and presses on the ice layer 201 to remove ice; when the hinge mechanism 500 is further rotated so that the end of the connecting rod 630 close to the hinge ring 510 first presses on the first inclined surface 5111, since the first inclined surface 5111 is an inclined surface, the first inclined surface 5111 pushes one end of the connecting rod 630 to different heights during the rotation process, causing the connecting rod 630 to slide, so that the other end of the connecting rod 630 presses on the force-bearing end 622 to cause the rotating block 620 to rotate, and the force-bearing end 622 gradually disengages from the ejector pin limit groove 611 during the rotation of 620; when the hinge mechanism 500 is further rotated, the end of the connecting rod 630 close to the hinge ring 510 first presses on the first inclined surface 5111, because the first inclined surface 5111 is an inclined surface, during the rotation process, the first inclined surface 5111 pushes one end of the connecting rod 630 to different heights, causing the connecting rod 630 to slide, thereby causing the other end of the connecting rod 630 to press on the force-bearing end 622 to cause the rotating block 620 to rotate, and during the rotation process of 620, the force-bearing end 622 gradually separates from the ejector pin limit groove 611 When the connecting mechanism 500 makes one end of the connecting rod 630 press against the second arc surface 5112, the force-bearing end 622 is separated from the ejector pin limiting groove 611, so that the ice-breaking ejector pin 610 releases the limiting effect of the tail, that is, the angle of the second arc surface 5112 is set according to the wires 200 of different sizes, so as to avoid the ice-breaking ejector pin 610 pressing against the wire 200 and causing damage. The second arc surface 5112 is an arc with the rotation center of the hinge mechanism 500 as the center. When the connecting rod 630 presses against the second arc surface 5112, it is in a stationary state. At this time, the hinge mechanism 500 is rotated to retract the ice-breaking ejector pin 610 into the first pressing block 110; when the hinge mechanism 500 is rotated to make one end of the connecting rod 630 press against the side of the third limiting block 5113, the hinge mechanism 500 cannot continue to rotate under the limiting effect of the third limiting block 5113, so as to avoid the wire 200 being damaged by over-tightening.

[0085] Before use, pull out the adjustment knob 550 and rotate it to drive the side gear 540 to rotate, and the side gear 540 drives the shaft end gear 530 to rotate, thereby rotating the articulated shaft 520, and the articulated shaft 520 drives the articulated ring 510 to rotate through the key slot, thereby achieving angle adjustment of the limit protrusion 511 to adapt to wires 200 of different sizes.

[0086] When one end of the connecting rod 630 is respectively pressed against the first inclined surface 5111 and the second curved surface 5112, the ice-breaking thimble 610 is respectively in two states: locked by the limiting end 621 and freely sliding up and down. When one end of the connecting rod 630 is pressed against the side of the third limiting block 5113, the first pressing block 110 is locked and clamped at an angle, so that the ice layer 201 is removed before the ice-breaking thimble 610 hits the conductor 200. When the ice-breaking thimble 610 hits the conductor 200, the ice-breaking thimble 610 slides upward to avoid damaging the conductor 200, and the third limiting block 5113 plays a limiting role.
