Description

Technical Field

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

[0002] An insulator is a special insulating control device that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. Gradually, many disc-shaped insulators are hung at one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass, ceramic, and silicone rubber composite materials.

[0003] When insulators are transported, they often collide with the transportation device due to shaking, causing damage to the metal heads at the upper and lower ends of the insulators and the insulator petticoats. These tiny cracks are likely to affect the use of the insulators. Therefore, during the transportation of insulators, they will be wrapped to prevent damage to their outer walls. Existing methods for protecting insulators include customizing silicone molds or winding foam plastics to protect the insulators. However, due to the different lengths and numbers of the upper petticoats of the insulators, the cost of customizing silicone molds is high, and the applicable range and practicality of using custom silicone molds for protection are low. When winding foam plastics, in order to ensure the protection effect, multiple layers need to be wrapped. Moreover, due to the irregular shape of the petticoats, it is difficult for the plastic foam paper to fit closely with the outer wall of the insulator. Not only is the disassembly and installation operation cumbersome, but also the protection effect is poor.

[0004] Therefore, how to design an insulator protection device that can solve the above technical problems is a technical problem to be solved. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide an insulator protection device, which solves the problems of high cost, low practicality, low application range, and poor protection effect of existing protection devices.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a left shell and a right shell with the same structure as the left shell and can be combined with the left shell to form a complete cylindrical shape; both the upper and lower ends of the left shell are provided with placement cavities, and anti-collision components are arranged along the circumferential direction in the placement cavities. The anti-collision components include telescopic rods, springs, and abutting plates. Installation grooves are opened on the inner side walls of the placement cavities. One end of the telescopic rod is arranged in the installation groove, the spring is arranged between the installation groove and the bottom of the telescopic rod, and the abutting plate is fixedly arranged at the end of the telescopic rod far from the spring; a buffer airbag is also covered on the inner side wall of the left shell, and an air guide pipe is communicated with the buffer airbag. The air guide pipe passes through the side wall of the left shell and extends to the outer wall of the left shell, and a sealing plug is detachably arranged at the port.

[0007] Furthermore, a damping gasket is fixedly sleeved on the outer peripheral wall of the telescopic rod of the telescopic rod.

[0008] Further, one end face of the abutting plate abutting against the insulator base is an arc surface adapted to the outer side wall of the insulator base.

[0009] Further, a silica gel soft film is further covered on the inner side surface of the buffer airbag.

[0010] The utility model has the following beneficial effects:

[0011] 1. By arranging the buffer airbag in the utility model, after being inflated and expanded by the inflation mechanism, it closely adheres to the insulator umbrella skirts of different lengths. When the left shell and the right shell are connected, the buffer airbag on the inner side surface thereof wraps the insulator umbrella skirts and the middle shaft as much as possible, avoiding shaking during transportation. It can be adapted to insulators with different umbrella skirt lengths and numbers of umbrella skirts at the same height, with low cost and high practicability.

[0012] 2. The anti-collision component is arranged circumferentially around the insulator metal head in the utility model. When the insulator in the shell is collided, the insulator metal head extrudes the abutting plate, and the abutting plate moves towards the spring direction. Under the elastic action of the spring, the impact received by the insulator metal head is reduced, avoiding direct collision between the insulator metal head and the inner wall of the shell and preventing damage to the outer wall of the insulator metal head.

[0018] The following further describes the utility model in detail with reference to the drawings and specific embodiments:

[0019] Refer to Figure 1-2 As shown, the solution includes a left shell 1 and a right shell 2 which has the same structure as the left shell 1 and can be combined with the left shell 1 to form a complete cylindrical shape.

[0020] Both the upper and lower ends of the left housing 1 are provided with placement cavities 11. An anti-collision component 12 is arranged along the circumferential direction in the placement cavity 11. The anti-collision component 12 includes a telescopic rod 121, a spring 122 and a contact plate 123. An installation groove 111 is formed on the inner side wall of the placement cavity 11. One end of the telescopic rod 121 is arranged in the installation groove 111. The spring 122 is arranged between the installation groove 111 and the bottom of the telescopic rod 121. The contact plate 123 is fixedly arranged at the end of the telescopic rod 121 far from the spring 122. A buffer airbag 13 is also covered on the inner side wall of the left housing 1. An air guide pipe 14 is communicated with the buffer airbag 13. The air guide pipe 14 passes through the side wall of the left housing 1 and extends to the outer wall of the left housing 1, and a sealing plug 141 is detachably arranged at the port.

[0021] Further, a damping gasket 1211 is fixedly sleeved on the outer peripheral wall of the telescopic rod 121 of the telescopic rod 121.

[0022] The end face of the contact plate 123 in contact with the insulator base is an arc surface adapted to the outer side wall of the insulator base, so that the contact plate 123 is in close fit with the outer edge of the insulator metal seat.

[0023] Further, in order to prevent, a silica gel soft film 131 is also covered on the inner side of the buffer airbag 13.

[0024] The working principle is roughly as follows:

[0025] Place the insulator into the left housing 1 (or the right housing 2). Place the metal heads (metal seats) at the upper and lower ends of the insulator between the contact plates 123 in the placement cavity 11. Connect an external inflation mechanism to the air guide pipe 14 to inflate the buffer airbag 13. After the buffer airbag 13 is inflated and expanded, its inner side is closely attached to the insulator umbrella skirt. Connect the right housing 2 (or the left housing 1) to the left housing 1 (or the right housing 2) (the left housing 1 and the right housing 2 are connected by means of clamping, fixed buckles, etc., and this embodiment does not limit). Inflate the buffer airbag 13 on the inner side wall of the other housing according to the above steps to make it expand and wrap the insulator umbrella skirt, so as to realize that the buffer airbags 13 on the inner side walls of the left housing 1 and the right housing 2 wrap the insulator umbrella skirt and the insulator middle axis in all directions.

[0026] When the left housing 1 and the right housing 2 are slightly collided or shaken, the metal seats at the upper and lower ends of the insulator touch the contact plate 123, and the telescopic rod 121 moves towards the installation groove 111 to squeeze the spring 122. The spring 122 generates a directional thrust on the contact plate 123, avoiding direct impact between the metal seats at the upper and lower ends of the insulator and the side wall of the housing, and reducing the impact force on the insulator.

[0027] The above are only specific embodiments of the present utility model, and do not thereby limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
