Description

Technical Field

[0001] The invention belongs to the technical field of insulators, in particular to an insulator installation device for a transformer substation. Background Art

[0002] Post insulators are insulating components used to support cables and prevent current from returning to the ground. They are used to support transmission conductors in overhead transmission lines and play a very important role. The insulator itself is not conductive. Ideally, the high-voltage line support frame is equivalent to a capacitor. The capacitance between conductors will have a certain leakage current under high voltage AC voltage. When the leakage current increases due to internal or external reasons, it indicates that the insulator has other conductive paths, such as cracks inside the insulator or dirt on the surface outside, which will bring safety hazards. Therefore, it is very important to keep the insulator clean during operation.

[0003] At the same time, the inventors found that when existing insulators support cables, they usually use manual binding to bind the cables to the top of the insulators. The operation process is very cumbersome and the work efficiency is low. When fixing the insulators on high-voltage power towers, they are mostly fixed with bolts. Since the number of bolts is large and scattered, workers need to carry more parts with them during installation. When working at high altitudes, the falling of parts will bring danger to the equipment and workers on the ground, and the bolts need to be installed and fixed one by one, resulting in low installation efficiency.

DETAILED DESCRIPTION

[0035] 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.

[0036] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-7As shown, the present invention is an insulator installation device for a substation, comprising an insulator body 1, wherein the insulator body 1 comprises a vertical rod 2 and an umbrella skirt portion 3 distributed in an array on the vertical rod 2, wherein the umbrella skirt portion 3 is evenly distributed along the height direction of the vertical rod 2; an upper clamp 4 and a lower clamp 5 are relatively arranged on the top of the vertical rod 2, wherein the upper clamp 4 and the lower clamp 5 are connected by bolts, and the upper clamp 4 and the lower clamp 5 are adjusted to match wires of different diameters, thereby realizing the function of adjustment. Meanwhile, the clamp designed in the present invention has a simple structure, is easy to operate, and has a low cost. Compared with the adjustment function realized by a complex mechanical structure, the present invention uses a clamp for adjustment, which is more cost-effective.

[0039] Furthermore, anti-skid rubber strips are arranged on the inner walls of the upper clamp 4 and the lower clamp 5. The anti-skid rubber strips can be arranged horizontally, vertically or obliquely, so as to achieve better anti-skid function.

[0040] A rotating ring 6 is rotatably connected at the edge of the umbrella skirt 3, and fan blades 7 are evenly distributed on the circumference of the rotating ring 6. The upper and lower parts of the vertical rod 2 close to the umbrella skirt 3 are respectively provided with connecting rings 8. The connecting ring 8 is rotatably connected to the vertical rod 2, and cleaning cotton 9 is arranged between the connecting ring 8 and the rotating ring 6.

[0041] In this embodiment, the fan blade 7 is designed to include a structure combining a horizontal fan blade 30 and a bent fan blade 31. The reason for this design is to fully extend the horizontal fan blade 30 beyond the coverage of the insulator body 1, so as to facilitate the use of wind power for rotation, and the bent fan blade 31 is to more efficiently use the wind power. The present invention can use wind power to drive the fan blade 7 to rotate in windy weather, and the fan blade 7 drives the rotating ring 6 and the connecting ring 8, so that the cleaning cotton 9 is used to clean the upper and lower surfaces of the umbrella skirt 3, and the cleaning effect is good and the new energy is fully utilized without causing additional burden and waste.

[0042] In practical applications, the bent sector 31 forms a certain angle with the horizontal plane, and in this embodiment, the angle is 160 degrees.

[0043] Furthermore, the bottom of the vertical rod 2 is provided with a limiting portion 10 and an installation box 11 used in cooperation with the limiting portion 10; in this embodiment, the limiting portion 10 includes a limiting circle 14 provided just below the vertical rod 2 and two limiting rods 15 provided on the limiting circle 14; the two limiting rods 15 are symmetrically provided at the edge of the limiting circle 14. A cavity is provided inside the installation box 11, and a through hole 12 matching the shape of the limiting portion 10 is provided on the top wall of the installation box 11. When in use, the limiting portion 10 can be passed through the through hole 12 into the interior of the installation box 11 by manually aligning the through hole 12 and the limiting portion 10 with the naked eye.

[0044] The bottom wall of the installation box 11 is provided with a protrusion 13 that matches the shape of the limiting portion 10. The limiting portion 10 that enters the installation box 11 is vertically inserted into the protrusion 13, so that the limiting portion 10 is limited in the left and right and front and back directions by the protruding edge of the protrusion 13. Since the shape of the protrusion 13 matches that of the limiting portion 10, the effect of limiting the limiting portion 10 by the protrusion 13 is good.

[0045] Furthermore, the bottom wall of the installation box 11 is also provided with a No. 1 slide groove 16 and a No. 2 slide groove 17 along the width direction of the limiting rod 15, and the No. 1 slide groove 16 and the No. 2 slide groove 17 are respectively arranged on both sides of the limiting rod 15; the No. 1 slide groove 16 and the No. 2 slide groove 17 are respectively provided with sliders 18, and the end of the slider 18 that penetrates into the interior of the installation box 11 is provided with a covering block 19, and the covering block 19 limits the limiting rod 15. In actual use, the covering block 19 is rectangular in shape and can cover half of the width of the limiting rod 15, so as to achieve a better limiting effect.

[0046] A lifting ring 20 is provided at one end of the sliding block 18 that passes through the outside of the installation box 11 , and a bidirectional screw 21 is provided inside the lifting ring 20 .

[0047] The bidirectional screw 21 is provided with a forward thread at a portion close to the first slide groove 16, and the bidirectional screw 21 is provided with a reverse thread at a portion close to the second slide groove 17;

[0048] Alternatively, the portion of the bidirectional screw 21 close to the No. 1 slide groove 16 is provided with a reverse thread, and the portion of the bidirectional screw 21 close to the No. 2 slide groove 17 is provided with a forward thread;

[0049] A smooth portion 22 is provided between the forward thread and the reverse thread.

[0050] The smooth portion 22 is provided between the forward thread and the reverse thread to prevent the limiting rod 15 from being squeezed and damaged due to excessive screwing.

[0051] The forward thread section and the reverse thread section of the bidirectional screw 21 of the present invention are respectively provided with a lifting ring 20, so that when the bidirectional screw 21 is manually screwed, the two lifting rings 20 can move in the same direction or in the reverse direction, thereby using the lifting ring 20 to drive the slider 18 to move. Before the limiter 10 is inserted into the through hole 12, the bidirectional screw 21 is first screwed, and the cover block 19 is screwed to a position away from the protrusion 13, so that there is no interference when the limiter 10 is inserted into the protrusion 13; after the limiter 10 is inserted into the protrusion 13, the bidirectional screw 21 is screwed in the reverse direction, so that the lifting ring 20 drives the cover block 19 to move to a suitable position to limit the limiter 10 in the upper and lower positions.

[0052] In order to facilitate the rotation operation, a screwing portion 29 is provided at one end of the bidirectional screw rod 21 , and the screwing portion 29 is circular in shape.

[0053] Furthermore, a receiving box 23 for receiving the bidirectional screw 21 is further provided at the bottom of the installation box 11 ; the receiving box 23 has a cavity structure, and the box body of the receiving box 23 is rotationally connected to the bidirectional screw 21 .

[0054] In this embodiment, the accommodating box 23 is used to limit and support the bidirectional screw 21 .

[0055] Embodiment 2:

[0056] See also Figure 8-9 As shown, the difference between this embodiment and the first embodiment is that a telescopic sleeve 24 is further provided at the top of the installation box 11, and the telescopic sleeve 24 includes a large sleeve 25 and a small sleeve 26, and the diameter of the large sleeve 25 is larger than the diameter of the small sleeve 26; the large sleeve 25 and the small sleeve 26 are slidably connected, and a spring 27 is provided inside the cavity of the large sleeve 25 and the small sleeve 26, and a clamping end 28 is provided at the end of the small sleeve 26, and the clamping end 28 is used to clamp the vertical rod 2. The above design realizes the secondary fixation of the insulator body 1, and at the same time, it can also make the overall structure more stable, and reduce the situation where water vapor enters the interior of the installation box 11 in rainy and snowy weather.
