Description

Technical Field

[0001] This utility model belongs to the field of insulator protection technology, and in particular relates to an external protection device for composite insulators. Background Technology

[0002] Composite insulators are widely used in power systems due to their advantages such as light weight and good pollution resistance. However, during transportation, storage and temporary outdoor placement, they are susceptible to external impacts, vibrations and environmental debris, which can lead to damage to the surface sheath and exposure of the core rod, thereby reducing insulation performance, shortening service life and increasing power grid operation and maintenance costs.

[0003] Existing protection methods have obvious defects. They lack a positioning and fixing structure, making them prone to tipping over or colliding during transportation or placement. Furthermore, they have poor shock absorption, and vibration can easily cause the internal structure to loosen. The protective measures are also limited, relying solely on a simple outer cover, which cannot effectively prevent the intrusion of debris such as gravel. Utility Model Content

[0004] The technical problem this invention aims to solve is the lack of a positioning and fixing structure, which makes the structure prone to tipping over or colliding during transportation or placement. Furthermore, the shock absorption effect is poor, and vibration can easily cause the internal structure to loosen. The protective measures are also limited, relying solely on a simple outer cover, which cannot effectively prevent the intrusion of debris such as gravel.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a composite insulator external protection device, including a base, wherein columns are fixedly connected to the top of the base and are symmetrically distributed in pairs, and further including...

[0006] A placement component, mounted on a column, includes a placement plate that passes through and is slidably connected to the column. Shock absorbers are fixedly connected between the bases of the placement plate and the bases of the placement plate. The shock absorbers are symmetrically distributed in pairs. A placement box with a recessed top is fixedly connected to the top of the placement plate. The top of the placement box is provided with a corresponding top sleeve, and the bottom wall of the top sleeve is recessed.

[0007] Furthermore, a pressure plate is slidably connected to the column, and an adjusting sleeve is rotatably connected to the top wall of the pressure plate. The adjusting sleeve is threadedly connected to the column, and the top sleeve is located directly below the pressure plate.

[0008] Furthermore, the pressure plate is slidably connected with sliding columns, which are symmetrically distributed in pairs. The lower end of the sliding column is fixedly connected to a connecting plate, the top sleeve is fixedly connected to the bottom of the connecting plate, and a spring is sleeved on the sliding column, with its two ends fixedly connected to the bottom wall of the pressure plate and the top wall of the connecting plate.

[0009] Furthermore, a guide rail is fixedly connected to the bottom wall of the pressure plate, and sliders that are relatively distributed to the left and right slide on the guide rail. An arc-shaped plate is fixedly connected to the bottom wall of the slider, and the bottom wall of the arc-shaped plate is in contact with the top wall of the connecting plate.

[0010] Furthermore, the arc-shaped plate is made of an elastic material, and a rubber column is fixedly connected between the arc-shaped plate and the guide rail.

[0011] Furthermore, the outer wall of the pressure plate is fixedly connected with evenly distributed semi-rings, and the outside of the column is provided with a protective net, which is hung inside the semi-rings by hooks.

[0012] Furthermore, the base has two symmetrically distributed bottom columns fixedly connected to its bottom wall. The center of each bottom column is recessed, and the recessed area is interference-fitted with the column.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) The recessed placement box on the top of the placement plate cooperates with the top sleeve to position the insulators up and down. The adjusting sleeve is tightened and the pressure plate is pressed down. It is used in conjunction with the elastic arc plate to fit the insulators and form a circumferential fixation. It can be stacked by inserting the bottom column into the upper end of the column.

[0015] (2) The shock absorber between the placement plate and the base can absorb transportation vibration. The spring on the sliding column, together with the elastic arc plate, can buffer the impact of external force. The double shock absorption structure replaces the traditional non-shock absorption design, avoids vibration causing the internal structure of the insulator to loosen, maintains the insulation performance, and reduces the power grid operation and maintenance cost.

[0016] (3) The external protective netting of the column is fixed by a semi-ring, which can block the intrusion of gravel and debris, solve the defect of the traditional simple outer protection, and fully protect the insulator from environmental debris damage. Attached Figure Description

[0023] like Figure 1-4 As shown, a composite insulator external protection device includes a base 1, which provides a supporting foundation for the entire device. Two symmetrically distributed bottom columns 19 are fixedly connected to the bottom wall. The center of the bottom column 19 is recessed. When multiple sets of devices need to be stacked for storage or transportation, the recessed part of the bottom column 19 of the upper device base 1 can be aligned with the column 2 on the top of the lower device. The interference fit between the recessed part and the column 2 can achieve stable stacking, greatly saving storage space and solving the problem of no stacking positioning structure in traditional protection methods. Two symmetrically distributed columns 2 are fixedly connected to the top of the base 1. The columns 2 provide installation support for placing components and pressure plates 7, ensuring that each component is assembled in an orderly manner in the vertical direction.

[0024] The column 2 is equipped with a placement assembly, which is the core structure for supporting the insulator. It includes a placement plate 3 that runs through the column 2 and is slidably connected to it. Two symmetrically distributed shock absorbers 4 are fixedly connected between the placement plate 3 and the base 1. The placement plate 3 can slide up and down along the column 2. The shock absorbers 4 can absorb the longitudinal vibration generated during transportation, prevent the vibration from being directly transmitted to the insulator, prevent the internal structure of the insulator from loosening due to long-term vibration, maintain its insulation performance, and reduce the subsequent operation and maintenance costs of the power grid. A placement box 5 with a recessed top is fixedly connected to the top of the placement plate 3. The placement box 5 is used to support the lower end of the insulator. The recessed structure can position the bottom of the insulator, prevent the insulator from shifting laterally, and lay the foundation for subsequent top fixing.

[0025] A pressure plate 7 is slidably connected to the column 2. An adjusting sleeve 8 is rotatably connected to the top wall of the pressure plate 7. The adjusting sleeve 8 is threadedly connected to the column 2. The top sleeve 6 is located directly below the pressure plate 7. When clamping the insulator, first put the lower end of the insulator into the placement box 5 of the placement plate 3, and then rotate the adjusting sleeve 8. Because the adjusting sleeve 8 is threadedly connected to the column 2, the rotation will drive the pressure plate 7 to slide down along the column 2 until the top sleeve 6 below the pressure plate 7 is close to the upper end of the insulator. The bottom wall of the top sleeve 6 is recessed and can fit against the upper end of the insulator. Together with the placement box 5, it can achieve the vertical positioning and fixation of the insulator, avoid the insulator from moving up and down during transportation or placement, solve the collision problem caused by the lack of positioning structure, and protect the surface sheath of the insulator from wear.

[0026] Two symmetrically distributed sliding columns 9 are slidably connected to the pressure plate 7. A connecting plate 10 is fixedly connected to the lower end of each sliding column 9. A top sleeve 6 is fixedly connected to the bottom of the connecting plate 10. A spring 11 is fitted on each sliding column 9. The two ends of the spring 11 are fixedly connected to the bottom wall of the pressure plate 7 and the top wall of the connecting plate 10, respectively. A guide rail 12 is fixedly connected to the bottom wall of the pressure plate 7. Sliding sliders 13, which are distributed symmetrically to the left and right, slide on the guide rail 12. An arc-shaped plate 14, made of elastic material, is fixedly connected to the bottom wall of the slider 13. The bottom wall of the arc-shaped plate 14 fits against the top wall of the connecting plate 10. A rubber column 15 is fixedly connected between the arc-shaped plate 14 and the guide rail 12. When the pressure plate 7 pushes the top sleeve 6 down, the top sleeve 6 contacts the upper end of the insulator, and the connecting plate 10 slides upward with the sliding column 9. The spring 11 is compressed, and the elastic force of the spring 11 can buffer the top sleeve 6, preventing the pressure plate 7 from being too high and damaging the insulator. At the same time, when the connecting plate 10 moves upward, it will squeeze the elastic arc plate 14. After being stressed, the arc plate 14 slides along the guide rail 12 through the slider 13, and the rubber column 15 deforms accordingly. The elastic material arc plate 14 can fit tightly against the side wall of the insulator to form a circumferential fixation, further preventing the insulator from shifting laterally. The spring 11, rubber column 15, and elastic arc plate 14 work together to buffer the impact of external forces during transportation. Together with the shock absorber 4 placed between the plate 3 and the base 1, a double shock absorption structure is formed, replacing the traditional non-shock-absorbing design, effectively preventing vibration from causing the internal structure of the insulator to loosen and extending the service life of the insulator.

[0027] The outer wall of the pressure plate 7 is fixedly connected with evenly distributed semi-rings 16. The outside of the column 2 is provided with a protective net 17. The protective net 17 is hung inside the semi-rings 16 by hooks 18. After the insulator is clamped, the protective net 17 is unfolded and hung on the semi-rings 16 of the pressure plate 7 by hooks 18. The protective net 17 can surround the outside of the column 2 to form a full-area shield. When placed outdoors or transported, the protective net 17 can prevent debris such as gravel and branches from entering the inside of the device, and avoid debris from hitting or adhering to the surface of the insulator, which would cause damage to the sheath. This solves the defects of traditional simple outer sheath protection, and fully protects the insulator from damage by environmental debris, maintaining its surface cleanliness and insulation performance.

[0028] The actual operation process is as follows:

[0029] Place the plate 3 through the column 2 and fix it to the shock absorber 4 between the base 1. Then put the pressure plate 7 on the column 2, rotate the adjusting sleeve 8 to fix the pressure plate 7 initially, and hang the protective net 17 on the half ring 16 of the pressure plate 7 through the hook 18 to complete the basic assembly of the device.

[0030] Open one side of the protective net 17, put the lower end of the insulator into the placement box 5 of the placement plate 3, rotate the adjusting sleeve 8 to move the pressure plate 7 down, so that the top sleeve 6 fits against the upper end of the insulator, until the spring 11 and the arc plate 14 form a stable buffer and circumferential fixation, and close the protective net 17.

[0031] If multiple sets need to be transported, align the recessed bottom column 19 of the upper device with the upright column 2 of the lower device, and stack them by interference fit. Use the protective net 17 and shock-absorbing structure to ensure the safety of the insulators during transportation.

[0032] After transportation or storage, open the protective net 17, rotate the adjusting sleeve 8 in the opposite direction to move the pressure plate 7 upward, and take out the insulator. If it needs to be used again, clean the debris inside the device and repeat the clamping steps.

[0033] The working principle of this utility model is as follows: the device is stacked and positioned by the cooperation of the base column 19 and the upright column 2. The insulator is fixed in multiple directions by the placement box 5, the top sleeve 6 and the arc plate 14. The shock absorber 4, the spring 11 and the elastic arc plate 14 are used to build double shock absorption. With the help of the protective net 17 and the partial enclosure structure, the device is isolated from debris. In the end, the problems of easy tipping, poor shock absorption and single protection of traditional protection methods are solved, and the protection needs of composite insulators for transportation, storage and outdoor placement are met.
