Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a suspension insulator. Background Art

[0002] Suspension insulators are generally made of insulating parts and metal accessories glued together or mechanically clamped with adhesive. They are widely used in power systems and usually belong to external insulation. They work under atmospheric conditions. They are a device that plays an important role in power systems. They are used for electrical insulation and mechanical fixation between electrical equipment or conductors that withstand potential differences. They mainly rely on their insulating parts to prevent current from passing through.

[0003] Suspension insulator monomers need to be combined into an insulator group consisting of multiple monomers and applied in the power system. When the suspension insulator monomers are combined, they are usually fixed with components such as bolts. During their operation, due to factors such as wind vibration, the bolts become loose, which can easily cause the end of the suspension insulator combination to fall off. It cannot be multi-locked and reinforced. Therefore, we propose a suspension insulator to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a suspension insulator to solve the problem raised in the above-mentioned background art that the suspension insulators currently on the market are usually fixed by bolts and other components when they are assembled. During their operation, due to factors such as wind vibration, the bolts become loose, which easily causes the ends of the suspension insulator assembly to fall off, and multiple locking and reinforcement cannot be performed.

[0005] To achieve the above object, the present invention provides the following technical solution: a suspension insulator, comprising an insulator shed, wherein the upper end of the insulator shed is connected to a steel cap, the lower end of the insulator shed is connected to a steel foot, and a limiting hole is provided inside the steel cap;

[0006] A limit ring is slidably connected to the outer wall of the steel cap, an adjustment shield is connected to the outer side of the limit ring, and a through slot is opened on the side wall of the adjustment shield;

[0007] The outer side of the steel cap is connected to a tension spring, the end of the tension spring is connected to a positioning rod, and the upper end of the positioning rod is threadedly connected to a first nut;

[0008] The steel cap is provided with a connection assembly for combining and reinforcing the insulator sheds.

[0009] Preferably, the connecting assembly includes a through hole opened inside the steel cap, a horizontal fixing rod passes through the interior of the through hole, a vertical fixing rod is sleeved on the outer side of the horizontal fixing rod, and a second nut is threadedly connected to the end of the horizontal fixing rod.

[0010] Preferably, the position of the limiting hole and the position of the through-slot are located in the same horizontal plane, and the height and width of the limiting hole are the same as the height and width of the through-slot.

[0011] Preferably, the adjustment shield forms a rotating structure through a limiting ring and a steel cap, the adjustment shield and a positioning rod are engaged with each other, and the upper end of the positioning rod is in a smooth arc shape.

[0012] Preferably, the highest point of the through hole is lower than the lowest point of the adjustment shield, and the adjustment shield is sleeved on the outside of the steel cap.

[0013] Preferably, the horizontal fixing rod and the vertical fixing rod are distributed perpendicular to each other, and two vertical fixing rods can be symmetrically sleeved on one end of the horizontal fixing rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) When the position of the through slot and the limiting hole of the suspension insulator corresponds to each other, the steel foot can be limited by inserting the steel foot into the limiting hole from the side and driving the adjustment cover to rotate so that the through slot opened on the side wall of the adjustment cover is offset from the position of the limiting hole. The positioning rod passes through the hole of the adjustment cover and the first nut is threadedly connected to the positioning rod, thereby achieving double locking of the insulator assembly end. The operation is convenient and the combination is stable.

[0016] (2) After the suspension insulator is assembled, the horizontal fixing rod is passed through the through hole opened in the steel cap, and the vertical fixing rod is symmetrically sleeved on the horizontal fixing rod and locked with a second nut. The horizontal fixing rod and the vertical fixing rod that are perpendicular to each other are used to reinforce and support the combined end of the insulator shed to prevent the combined end from being damaged due to its own gravity when it is suspended. When the insulator unit is disassembled, the insulator unit at the adjacent position is supported to prevent the adjacent insulating unit from falling, making it easier to disassemble and replace the insulating unit.

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 7 The utility model provides the following technical solution: a suspension insulator, comprising an insulator shed 1, the upper end of the insulator shed 1 being connected to a steel cap 2, the lower end of the insulator shed 1 being connected to a steel foot 3, a limit hole 4 being provided inside the steel cap 2; a limit ring 5 being slidably connected to the inner wall of the outer wall of the steel cap 2, an adjustment shield 6 being connected to the outer side of the limit ring 5, and a through slot 7 being provided on the side wall of the adjustment shield 6;

[0027] Furthermore, the position of the limiting hole 4 and the position of the through-slot 7 are located in the same horizontal plane, and the height and width of the limiting hole 4 are the same as the height and width of the through-slot 7. The insulator shed 1 can be disassembled and assembled by adjusting the relative positions of the limiting hole 4 and the through-slot 7. By making the position of the limiting hole 4 correspond to the position of the through-slot 7, the restriction on the steel leg 3 is released, and the insulator shed 1 can be removed. By staggering the position of the limiting hole 4 and the position of the through-slot 7, the steel leg 3 can be restricted, and the insulator shed 1 can be assembled.

[0028] The outer side of the steel cap 2 is connected to a tension spring 8, the end of the tension spring 8 is connected to a positioning rod 9, and the upper end of the positioning rod 9 is threadedly connected to a first nut 10;

[0029] Furthermore, the adjusting shield 6 forms a rotating structure with the limit ring 5 and the steel cap 2, and the adjusting shield 6 and the positioning rod 9 are engaged with each other. The upper end of the positioning rod 9 is a smooth arc shape, and the position of the through-slot 7 can be flexibly adjusted by rotating the adjusting shield 6. When the adjusting shield 6 rotates, it can slide on the upper end of the positioning rod 9.

[0030] The steel cap 2 is provided with a connection assembly for combining and reinforcing the insulator shed 1;

[0031] Furthermore, the connecting assembly includes a through hole 11 formed inside the steel cap 2, a horizontal fixing rod 12 passing through the through hole 11, a vertical fixing rod 13 sleeved on the outside of the horizontal fixing rod 12, and a second nut 14 threadedly connected to the end of the horizontal fixing rod 12;

[0032] Furthermore, the highest point of the through hole 11 is lower than the lowest point of the adjustment shield 6, and the adjustment shield 6 is sleeved on the outside of the steel cap 2, so as to prevent the adjustment shield 6 from obstructing the horizontal fixing rod 12 from passing through the through hole 11, and also prevent the horizontal fixing rod 12 from obstructing the rotation of the adjustment shield 6;

[0033] Furthermore, the horizontal fixing rod 12 and the vertical fixing rod 13 are arranged perpendicular to each other, and two vertical fixing rods 13 can be symmetrically sleeved on one end of the horizontal fixing rod 12. The horizontal fixing rod 12 and the vertical fixing rod 13 are used to reinforce and support the connection end of the insulator shed 1, and prevent the remaining insulator units from falling when the insulator units are disassembled;

[0034] Specifically, the insulator shed 1 is assembled, and the steel foot 3 is gradually pushed from the side into the limiting hole 4 opened in the steel cap 2. The limiting hole 4 limits the steel foot 3 up and down. Then the adjusting cover 6 is rotated so that the adjusting cover 6 rotates on the outside of the steel cap 2 through the limiting ring 5 until the hole opened at the adjusting cover 6 corresponds to the position of the positioning rod 9. At this time, the tension spring 8 in the stored force state controls the positioning rod 9 to move up and reset, and the positioning rod 9 is extended through the hole opened in the adjusting cover 6. The first nut 10 is threadedly connected to the positioning rod 9. The first nut 10 and the positioning rod 9 The adjusting cover 6 is double-locked. At this time, the through-slot 7 opened on the side wall of the adjusting cover 6 is staggered with the position of the limiting hole 4. The adjusting cover 6 can be used to limit the steel foot 3 in the horizontal direction to realize the assembly of the insulator shed 1. When it is necessary to disassemble the single body, it is only necessary to pull down the positioning rod 9. The positioning rod 9 stretches and stores the tension spring 8. The positioning rod 9 moves to the lower side of the adjusting cover 6, and the adjusting cover 6 can be driven to rotate. The position of the through-slot 7 is aligned with the position of the limiting hole 4, so that the limit of the steel foot 3 can be released and the insulator shed 1 can be disassembled.

[0035] After the insulator sheds 1 are assembled one by one, the horizontal fixing rods 12 can be passed through the through holes 11 opened in the steel caps 2, the ends of two adjacent horizontal fixing rods 12 are sleeved with vertical fixing rods 13, and the second nuts 14 are threadedly connected to the ends of the horizontal fixing rods 12. The horizontal fixing rods 12 and the vertical fixing rods 13, which are arranged perpendicular to each other, are used to reinforce and support the combined ends of the insulator sheds 1 again to prevent the combined ends from being damaged due to their own gravity when they are hung for use. Matters not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
