Description

TECHNICAL FIELD

[0002] The insulator plays two basic roles in the overhead transmission line, namely supporting the conductor and preventing the current from returning to the ground, both of which must be guaranteed. However, in actual use, the insulator is contaminated by dirt, etc., and the presence of dirt can cause the insulator to form a pollution flashover during use, thereby causing flashover breakdown, etc. Therefore, the porcelain insulator needs to be cleaned. However, the existing cleaning device has a complex structure or high use cost.

[0003] In addition, the needle type porcelain insulator is usually used to fix the high-voltage line. In use, the cable is tightly attached to the top groove or side groove of the needle type insulator, and then the cable is bundled and fixed with the needle type insulator in a winding manner. This way is relatively inefficient, and the bundling method and the tightness of the bundling have no uniform standard, and are highly random, which can easily lead to loose winding and even loosening after long-term use. At the same time, there is a structure for fixing the high-voltage line by screwing the bolt, which can limit the position of the high-voltage line, but it needs a tool to operate it, which can cause certain safety hazards for high-altitude work.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0022] As Figures 1 to 17 ​​​​​​​​​As shown, this anti-pollution high-voltage needle-type porcelain insulator of the present invention includes a porcelain insulator 1 and a cleaning assembly 2. The cleaning assembly 2 is disposed on the porcelain insulator 1. The cleaning assembly 2 is driven by wind to rotate on the porcelain insulator 1, thereby cleaning the surface of the shed 3 on the porcelain insulator 1. Example

[0023] The porcelain insulator 1 consists of a bearing component 4 and an insulator body 5. The bearing component 4 is connected to the insulator body 5 by bolts 6 and is located on the upper end of the insulator body 5. The bearing component 4 is used to support and fix the high-voltage line 7. The bearing component 4 is used to cooperate with the insulator body 5 to fix and position the high-voltage line 7.

[0024] like Figure 6 As shown, the insulator body 5 is provided with an upper connecting rod 8, a shed 3, a lower connecting rod 9, and a fixing frame 10. The shed 3 has a large shed 3 and a small shed 3, which are spaced apart and are provided in multiples.

[0025] A connecting plate 11 is provided on the upper connecting rod 8, and the diameter of the connecting plate 11 is larger than the diameter of the upper connecting rod 8. A sliding hole 12 is provided in the middle of the connecting plate 11, and the sliding hole 12 extends into the upper connecting rod 8. The depth of the sliding hole 12 is greater than the length of the rod body 13, so that a clearance area 14 is formed between the rod body 13 and the bottom wall of the sliding hole 12, which allows the rod body 13 to continue to move downward within the sliding hole 12. The connecting plate 11 is also provided with symmetrically arranged hinge arms 15 and limiting arms 16, which are spaced apart.

[0026] The upper end of the hinge arm 15 is provided with a curved extension end 17, which is symmetrically arranged and bends towards the center to facilitate the hinge arm 15 entering the movable hole 18. A hinge region 19 is formed between the extension ends 17 and the retainer 25 is hinged within the hinge region 19. The extension end 17 is provided with a second hinge hole 21 that mates with the hinge rod 20.

[0027] The bearing assembly 4 includes a fixed ring 22, a movable member 23, a pressure plate 24, and symmetrically arranged retaining members 25. The fixed ring 22 is connected to the connecting plate 11 by bolts 6. The fixed ring 22 has a movable hole 18 in the middle that mates with the sliding hole 12. The inner diameter of the movable hole 18 is larger than the inner diameter of the sliding hole 12. A spring 26 is installed in the movable hole 18. The movable member 23 is inserted into the sliding hole 12 through the movable hole 18 and is located in the middle of the spring 26. The pressure plate 24 is sleeved on the movable member 23 and is located at the upper end of the spring 26. The retaining member 25 is hinged to the hinge arm 15 through the hinge rod 20. The movable member 23 and the retaining member 25 are in contact and limited. When the retaining member 25 is moved, it pushes the movable member 23 to compress the spring 26 through the pressure plate 24.

[0028] The upper connecting rod 8 is provided with a positioning protrusion 27, which cooperates with the positioning pin 28 to keep the positioning pin 28 at the lower end of the positioning protrusion 27. The outer diameter of the positioning protrusion 27 is smaller than that of the connecting disc 11, and the positioning protrusion 27 is used to cooperate with the positioning pin 28. When the positioning pin 28 is rotated, the positioning pin 28 is kept at the lower end of the positioning protrusion 27 at the middle position, thereby preventing the positioning pin 28 from moving upward and limiting the position of the entire cleaning assembly 2.

[0029] The movable part 23 is composed of the rod body 13 and the symmetrically arranged first limiting block 29 and second limiting block 30. The first limiting block 29 is at the upper end of the second limiting block 30, and the length of the first limiting block 29 is greater than that of the second limiting block 30. The first limiting block 29 and the second limiting block 30 cooperate with each other to limit the rotation of the rotating rod 31 and can cooperate with the rotating rod 31 to drive the movable part 23 to move up and down.

[0030] A through hole 32 is arranged in the middle of the pressing disc 24, and the rod body 13 is arranged in the through hole 32. The hinged arm 15 and the limiting arm 16 are arranged between the movable hole 18 and the pressing disc 24. The pressing disc 24 is pushed by the retaining member 25 to compress the spring 26. When the limiting pin 33 is not removed from the first insertion hole 34 and the second insertion hole 35, the movable part 23 is prevented from moving downward. Even if the retaining member 25 is rotated to push the pressing disc 24 through the contact plane 36 of the retaining member 25, the rotating rod 31 is limited by the first limiting block 29 and the second limiting block 30, thereby avoiding the rotation of the retaining member 25 and causing the high-voltage line 7 to move out of the first limiting opening 37 and the second limiting opening 38.

[0031] The first insertion hole 34 is arranged at the lower end of the rod body 13, and the second insertion hole 35 is arranged on the upper connecting rod 8 and communicates with the sliding hole 12. The first insertion hole 34 and the second insertion hole 35 cooperate, and a limiting pin 33 is arranged in the first insertion hole 34 and the second insertion hole 35. One end of the limiting pin 33 is provided with a small hole 39, which can accommodate the spring 26 pin. Of course, an R-shaped split pin can also be directly inserted into the first insertion hole 34 and the second insertion hole 35.

[0032] The retaining member 25 is provided with a guide arc surface 40, a movable groove 41, and a first limiting port 37. The movable groove 41 is located at the guide arc surface 40 and is arc-shaped, used to push the pressure plate 24. A rotating rod 31 is provided in the movable groove 41, and the rotating rod 31 is tangentially connected to the guide arc surface 40. The rotating rod 31 is located in the sliding area 42 between the first limiting block 29 and the second limiting block 30. The fixing ring 22 is provided with a second limiting port 38 that cooperates with the first limiting port 37. Both the first limiting port 37 and the second limiting port 38 are open semi-circles. After the first limiting port 37 and the second limiting port 38 are combined, the first limiting port 37 and the second limiting port 38 form a complete circle, which facilitates the placement of the high-voltage line 7.

[0033] A sliding region 42 is formed between the first limiting block 29 and the second limiting block 30, and the rotating rod 31 is disposed within the sliding region 42. Figure 9 As shown, the distance between the outer wall surface M of the second limiting block 30 and the center line of the rod 13 is H3, the distance between the outer wall surface M of the first limiting block 29 and the center line of the rod 13 is H4, and the distance between the center line of the rotating rod 31 and the center line of the rod 13 is H5, where H3 = H5 < H4.

[0034] Since the first limiting block 29 is longer and the second limiting block 30 is shorter, the position of the rotating rod 31 is restricted by the first limiting block 29 and the second limiting block 30.

[0035] The lower end of the retainer 25 forms a contact plane 36, the first limiting port 37 is provided on the contact plane 36, the contact plane 36 is provided on the pressure plate 24, and part of the contact plane 36 is provided on the pressure plate 24, while most of it is placed on the fixing ring 22.

[0036] like Figure 8 As shown, the retainer 25 has a first hinge hole 43, and the hinge rod 20 is disposed in the first hinge hole 43. The distance between the center line of the first hinge hole 43 and the contact plane 36 is H1, and the distance between the center line of the first hinge hole 43 and the center line of the rotating rod 31 is H2, where H1 < H2. Therefore, when the retainer 25 rotates around the hinge rod 20, it will gradually push the pressure plate 24 through the guide arc surface 40, moving it from the contact plane 36 (which is a shorter distance away) to the position of the rotating rod 31. This gradually increases the distance between the pressure plate 24 and the hinge rod 20, pushing the pressure plate 24 and compressing the spring 26.

[0037] like Figure 16As shown, at this time, the spring 26 is in a compressed state, and the spring 26 has a certain elastic force to push the pressing disc 24 upwards, so that the retaining member 25 is in a forced and limited state, the spring 26 pushes the pressing disc 24 to drive the retaining member 25 to rotate around the hinge rod 20, and the retaining member 25 drives the movable member 23 to move.
