Description

Technical Field

[0001] The present invention belongs to the technical field of lightning protection devices, and particularly relates to a lightning protection device for distribution lines. Background Art

[0002] As an important part of the power system, the distribution line undertakes the key task of electric energy transmission. However, its outdoor installation characteristic makes it extremely vulnerable to lightning strikes. Lightning has the characteristics of instantaneous high voltage and large current, which may cause accidents such as line tripping, insulator flashover, and wire fusing, seriously affecting the power supply reliability. The lightning protection system is mainly used to protect various electrical equipment (transformers, switches, capacitors, wave traps, current transformers, engines, motors, power cables, etc.) in the power system, railway electrification system, and communication system from being damaged by lightning overvoltage, switching overvoltage, etc. The main types of lightning protection systems include tube lightning arresters, valve lightning arresters, and drop-out lightning arresters, etc.

[0003] The breakdown voltage of the air gap is directly related to its distance. By adjusting the distance between the electric rods, the trigger voltage threshold of the device can be accurately set to be slightly lower than the insulation tolerance level of the protected line or equipment. The common method for adjusting the distance between electric rods generally realizes the adjustment of the distance through the driving method of adding gaskets or screws. However, the distance adjusted by the gasket is not accurate enough. The traditional screw adjustment method generally adopts a longitudinal design, which will expose the entire screw and the parts connected to the screw to the atmosphere. Over time, it will cause thread slipping, and then lead to a change in the distance between the electric rods. Summary of the Invention

[0023] 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.

[0024] Please refer to Figures 1-10 As shown, the present invention is a lightning protection device for a distribution line, including: a cable 1, an upper fitting 2 sleeved outside the cable 1, a lower fitting 3 connected to the bottom of the upper fitting 2, a lightning attracting convex column 4 connected to one side of the lower fitting 3 near the top, and a composite umbrella skirt 5 longitudinally and spaced outside the lower fitting 3; wherein the upper fitting 2 is fixed to the cable 1, and the upper fitting 2 can puncture the insulating layer of the cable 1 and communicate with the conductive core of the cable 1. The lightning attracting convex column 4 is electrically connected to the upper fitting 2. The end of the lightning attracting convex column 4 inclines downward and leaves a certain distance from the top of the lightning attracting rod 41.

[0025] A lightning attracting sleeve ring 40 is sleeved outside the lightning attracting rod 41. In order to complete the installation of the lightning attracting rod 41, a columnar lightning attracting sleeve ring 40 is sleeved outside the lightning attracting rod 41. A middle hole through which the lightning attracting rod 41 longitudinally passes is opened at the center of the lightning attracting sleeve ring 40. A longitudinal inner groove 48 of the sleeve ring communicating with the middle hole is also opened on the surface of the lightning attracting sleeve ring 40. A positioning insertion strip plate 45 longitudinally sliding along the groove of the longitudinal inner groove 48 of the sleeve ring is fixedly arranged on the outer wall of the lightning attracting rod 41. In actual operation, when the lightning attracting rod 41 is longitudinally inserted from the top of the lightning attracting sleeve ring 40, the positioning insertion strip plate 45 needs to be longitudinally moved along the groove of the longitudinal inner groove 48 of the sleeve ring. A sleeve ring adjusting bottom ring 42 with an annular structure is arranged at the bottom of the lightning attracting convex column 4. The sleeve ring adjusting bottom ring 42 can rotate at the bottom of the lightning attracting sleeve ring 40. In order to complete the rotation, an annular upward concave annular groove is opened at the bottom of the lightning attracting sleeve ring 40, and an annular slider slidably adapted to the annular groove is fixedly arranged at the top of the sleeve ring adjusting bottom ring 42. After the bottom of the lightning attracting sleeve ring 40 is attached to the top of the sleeve ring adjusting bottom ring 42, the sleeve ring adjusting bottom ring 42 can rotate independently. In order to complete the limit of the lightning attracting rod 41, an arc-shaped downward concave bottom ring top opening groove 44 is opened at the top of the sleeve ring adjusting bottom ring 42 and located between the annular slider and the middle hole, and the center of the bottom ring top opening groove 44 is divided by a top opening partition plate 43, so that the bottom ring top opening groove 44 has two downward concave spaces; An arc-shaped insertion rod 46 and an arc-shaped spring 47 are respectively arranged in the space of the top groove 44 of the bottom ring. The side surface of the arc-shaped insertion rod 46 is fixed to the top groove partition plate 43, and a positioning transverse hole is opened at the bottom of the positioning insertion strip plate 45. When the bottom ring 42 is adjusted by rotating the collar alone, the arc-shaped insertion rod 46 is horizontally screwed into the positioning transverse hole of the positioning insertion strip plate 45, and the positioning insertion strip plate 45 can be inserted and limited by the arc-shaped insertion rod 46. At this time, the bottom of the positioning insertion strip plate 45 is attached to the bottom of the top groove 44 of the bottom ring. At the same time, in order to complete the rotation of the collar to adjust the bottom ring 42, the arc-shaped insertion rod 46 is kept inserted into the positioning transverse hole of the positioning insertion strip plate 45 without external force. An arc-shaped spring 47 is installed in the groove of the other group of top grooves 44 of the bottom ring, and the arc-shaped spring 47 is fixed to the side wall of the top groove partition plate 43. The other end of the arc-shaped spring 47 is combined with the downward protrusion at the bottom of the lightning attracting collar 40. The protrusion extends into the groove of the top groove 44 of the bottom ring, and the protrusion is away from one side of the top groove 44 of the bottom ring in the default state. When the lightning rod 41 needs to be inserted into the lightning attracting collar 40, first rotate the collar to adjust the bottom ring 42 to compress the arc-shaped spring 47 by the protrusion. At this time, the arc-shaped insertion rod 46 is separated to one side position of the positioning insertion strip plate 45. After the bottom of the positioning insertion strip plate 45 reaches the bottom of the top groove 44 of the bottom ring, release the collar to adjust the bottom ring 42. Through the elastic release of the compressed arc-shaped spring 47, the top groove partition plate 43 is driven, and then the collar is driven to adjust the rotation of the bottom ring 42, so that the arc-shaped insertion rod 46 can be automatically inserted into the positioning transverse hole at the bottom of the positioning insertion strip plate 45, and the lightning rod 41 can be positioned and installed, thereby completing the rapid installation of the lightning rod 41 and the lightning attracting collar 40.

[0026] The bottom of the lower fitting 3 is fixedly provided with an installation bracket 6, and the bottom of the installation bracket 6 is fixedly provided with an upwardly protruding positioning convex block portion 13. The side wall of the functional main chamber 16 is fixedly provided with a plugging side plate 14 extending into the inner side of the installation bracket 6. The bottom of the plugging side plate 14 is provided with a positioning bottom jack portion 15 for plugging connection with the positioning convex block portion 13. A bracket center hole 7 is provided inside the lower fitting 3. A spring portion 8 is installed in the groove of the bracket center hole 7. The bottom of the spring portion 8 is connected with a moving inner block 9. The bottom of the bracket center hole 7 is provided with a bottom jack 11 communicating with the bracket center hole 7. The bottom of the moving inner block 9 is fixedly provided with an inner plugging rod portion 12 longitudinally sliding in the hole of the bottom jack 11. The top of the plugging side plate 14 is provided with a round hole for plugging and positioning with the inner plugging rod portion 12, and the round hole communicates with the positioning bottom jack portion 15. A waist hole communicating with the bracket center hole 7 is also provided on the side of the lower fitting 3. The side wall of the moving inner block 9 is fixedly provided with a longitudinal dial block 10 extending outwards through the waist hole. The installation bracket 6 is designed in a side U-shaped structure, so that the functional main chamber 16 drives the plugging side plate 14 to horizontally extend into the inner side of the installation bracket 6 along the opening of the installation bracket 6. Then, the opening of the positioning bottom jack portion 15 is vertically sleeved outside the positioning convex block portion 13. The positioning convex block portion 13 is in a square column shape and can be pluggingly adapted to the opening of the positioning bottom jack portion 15. After the positioning bottom jack portion 15 is inserted outside the positioning convex block portion 13, the preliminary installation of the functional main chamber 16 is completed; At the same time, in the initial state, there is also a set of positioning convex block portions 13 at the side opening position of the installation bracket 6 and above the positioning convex block portion 13 for interception. The inner plugging rod portion 12 can longitudinally slide in the groove of the bottom jack 11. Before the plugging side plate 14 is installed, it is necessary to completely retract the inner plugging rod portion 12 into the bottom jack 11. The top of the inner plugging rod portion 12 is connected with the longitudinal dial block 10 through the moving inner block 9, and the longitudinal dial block 10 is located outside the installation bracket 6. By lifting the longitudinal dial block 10, the spring portion 8 can be compressed, so that the moving inner block 9 moves upwards in the hole of the bracket center hole 7. Since the opening of the bracket center hole 7 has a length limit, the spring portion 8 will be compressed. At this time, the inner plugging rod portion 12 moves upwards in the hole of the bottom jack 11, so that the inner plugging rod portion 12 retracts into the bottom jack 11. On the contrary, after the plugging side plate 14 is placed, release the longitudinal dial block 10 so that the bottom of the inner plugging rod portion 12 longitudinally inserts into the round hole at the top of the plugging side plate 14 to complete the positioning installation of the plugging side plate 14.

[0027] On one side of the lightning attracting collar 40, a main displacement sleeve plate 63 is fixedly installed. A support sliding sleeve plate 64 is slidably connected to the side surface of the main displacement sleeve plate 63. The main displacement sleeve plate 63 longitudinally slides on the surface of the support sliding sleeve plate 64, so as to realize the adjustment of the height of the lightning attracting collar 40, and further realize the adjustment of the height of the lightning attracting rod 41. The bottom of the main displacement sleeve plate 63 is fixedly connected to the main function chamber 16. The support sliding sleeve plate 64 is fixedly installed on the side surface of the main function chamber 16. There is a function inner cavity 17 inside the main function chamber 16. A horizontally arranged adjusting screw rod 19 is arranged inside the function inner cavity 17. An engaging sleeve 21 is externally engaged with the adjusting screw rod 19. At the bottom of the engaging sleeve 21, a linkage vertical plate 24 extending downward through the bottom of the main function chamber 16 is fixedly installed. A linkage horizontal plate 28 is fixedly installed at the bent part of the linkage vertical plate 24. And a bottom horizontal groove 23 allowing the linkage vertical plate 24 to pass through is opened at the bottom of the main function chamber 16. And the bottom horizontal groove 23 has a certain length, so that the linkage vertical plate 24 can horizontally move along the groove of the bottom horizontal groove 23. And in order to improve the stability of the engaging sleeve 21, a sliding support plate 22 is fixedly installed on the side surface of the engaging sleeve 21, so that the bottom of the sliding support plate 22 can slide along the inner bottom of the function inner cavity 17; In order to realize that the linkage horizontal plate 28 can drive the main displacement sleeve plate 63 to perform longitudinal displacement, a lifting slope plate 30 is fixedly installed at the bottom of the main displacement sleeve plate 63. A bottom slope groove 32 is opened at the bottom of the top end of the lifting slope plate 30. A moving inclined slider 31 is slidably connected in the groove of the bottom slope groove 32. The moving inclined slider 31 and the linkage horizontal plate 28 are connected by plugging through a U-shaped plug-in 29. A top anti-detachment groove 33 is also opened above the groove of the bottom slope groove 32. A slider extending into the groove of the top anti-detachment groove 33 is fixedly installed at the top of the moving inclined slider 31. The whole moving inclined slider 31 can slide along the grooves of the top anti-detachment groove 33 and the bottom slope groove 32. And because the bottom of the lifting slope plate 30 is overall inclined, and when the moving inclined slider 31 is combined with the linkage horizontal plate 28 through the U-shaped plug-in 29, when the linkage horizontal plate 28 moves horizontally, the moving inclined slider 31 will also move along the groove of the bottom slope groove 32. And under the longitudinal restriction of the main displacement sleeve plate 63, when the moving inclined slider 31 moves along the groove of the bottom slope groove 32, the whole lifting slope plate 30 will drive the main displacement sleeve plate 63 to perform longitudinal movement, and further realize the adjustment of the height of the lightning attracting collar 40; In order to facilitate the rotation operation of the adjusting screw rod 19, a closing side plate 18 is installed at the side opening of the main function chamber 16, so that one end of the adjusting screw rod 19 passes through the closing side plate 18 and extends outward and a screw rod torsion groove 20 is arranged.

At the bottom of the L-shaped plate and on one side of the marking cross bar 26, a scale indicator plate 27 is provided. Due to the lateral movement of the linkage vertical plate 24, the marking cross bar 26 can move laterally on one side of the scale indicator plate 27. The index of the scale indicator plate 27 corresponding to the marking cross bar 26 can remotely obtain the position of the moving inclined slider 31 in the bottom slope groove 32 through a camera and lighting tool, and then the distance between the top of the lightning attracting rod 41 and the bottom of the lightning attracting convex column 4 can be judged.

[0029] Column vertical holes 38 are formed on the surfaces of the two groups of connecting side columns 37. An internal spring 39 is installed in the groove of the column vertical hole 38. The bottom end of the internal spring 39 is connected to a horizontal plate main board 35. Multiple groups of horizontally distributed horizontal plate top grooves 34 are formed at the top of the linkage horizontal plate 28. At the bottom of the horizontal plate main board 35, a horizontal plate pressing strip 36 is fixedly arranged, which is longitudinally inserted and adapted to the horizontal plate top groove 34. In order to further maintain the stability of the linkage horizontal plate 28 and thus improve the stability of the position of the lifting slope plate 30, after the displacement of the linkage horizontal plate 28 is completed, by releasing the horizontal plate main board 35, the internally compressed spring 39 releases its elastic force and drives the horizontal plate main board 35 to move downward, so that the horizontal plate pressing strip 36 is clamped into the corresponding horizontal plate top groove 34. And at the bottom of each horizontal plate pressing strip 36, there is a friction part with a relatively large friction coefficient, which has a large friction when contacting the top of the horizontal plate top groove 34, and thus can assist in improving the stability of the linkage horizontal plate 28.

A retention inner hole 60 is opened on the side of the retention bin 59. A retention opening 62 communicating with the retention inner hole 60 is opened at the opening part of the retention bin 59. An elastic plate 61 is installed in the groove of the retention inner hole 60. An impeller top column 53 is also fixedly installed on the top of the shaftless impeller 52. The impeller top column 53 is in the shape of a multi-prismatic column. When the motor 49 drives the rotating connecting rod 50 to rotate, the impeller top column 53 can enter the retention opening 62 after rotation and then continue to enter the retention inner hole 60. The elastic plate 61 is placed in the retention inner hole 60, and the opening in front of the elastic plate 61 is relatively small. When the impeller top column 53 forcibly enters, the elastic plate 61 is pried open, and then it enters the inner side of the elastic plate 61. Since the elastic plate 61 itself is forced to deform, it has an inward pressure and can continuously press on the impeller top column 53, so that the shaftless impeller 52 will not rotate when not necessary. A functional sleeve 55 is also arranged between two shaftless impellers 52 distributed up and down, and the functional sleeve 55 is fixed to the rotating column 51. The functional sleeve 55 can rotate with the rotating column 51. A positioning screw hole part 56 is opened on the surface of the functional sleeve 55. The reflective plate 57 can be attached to the side of the functional sleeve 55. After the opening of the reflective plate 57 corresponds to the positioning screw hole part 56, the reflective plate 57 is installed outside the functional sleeve 55. The rotating column 51 drives the functional sleeve 55 to rotate, so that the reflective plate 57 rotates. After the reflective plate 57 rotates, it can emit light to drive away the nearby bird flocks.
