Background

The insulator is a special insulating control, can play an important role in overhead transmission lines, is used for supporting and fixing power transmission wires and charged bodies and enables enough insulating distances to be reserved among the charged bodies, between the charged bodies and the ground or among the power transmission wires. Because the insulator used on the high-voltage motor is low in height, birds are easy to attract to nest, and therefore adverse effects are brought to power transmission.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an insulator for high-voltage motor can effectually prevent birds from nesting on insulator upper portion.

In order to achieve the above purpose, the technical scheme of the utility model is that:

an insulator for a high-voltage motor comprises a body and a nesting prevention device arranged on the body; the nesting prevention device comprises a bearing disc, the bearing disc comprises an upper disc, a lower disc and a connecting rod for connecting the upper disc and the lower disc, the lower disc is positioned in a mounting hole formed in the upper end of the body, and a first return spring for supporting the bearing disc is further arranged in the mounting hole; the body is also provided with a supporting disc, the supporting disc is of an umbrella-shaped annular structure, and the supporting disc is formed by splicing a plurality of supporting sheets; the lower surface of the supporting sheet is hinged with the upper end face of the body through a pin shaft, a clamping plate is vertically arranged on the edge of the inner ring of the supporting sheet downwards, the lower end of the clamping plate is pressed against the side wall of the lower disc under the action of the gravity of the supporting sheet, and a turning channel for the clamping plate to pass through is radially arranged on the upper disc.

Furthermore, a second return spring is arranged on the lower surface of the supporting piece and is positioned on the outer side of the pin shaft.

Furthermore, one side of the lower end face of the clamping plate, which is far away from the lower disc, is an arc surface.

Has the advantages that: 1. the utility model discloses in can be aroused when preventing that the device of nesting from receiving the weight (for example the gravity oppression of bird's nest) to make the backing sheet in the backing sheet can overturn downwards, the support that the bird's nest bottom has not had the backing sheet this moment can drop from preventing the device of nesting naturally, has played a better bird pest prevention effect. 2. The backing sheet still can resume to initial position under second reset spring's effect after upset down to guaranteed the utility model discloses can function repeatedly. 3. The arc surface can ensure the smooth and easy recovery of the clamping plate to the original position.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The insulator for the high-voltage motor shown in fig. 1 to 3 comprises a body 1 consisting of a plurality of insulating sheds and a connecting shaft, and a nesting prevention device 2 arranged at the upper end of the body. The nesting prevention device 2 comprises a bearing plate 21 and a supporting plate 22 positioned by the bearing plate in a clamping manner. Specifically, the bearing plate includes an upper disc 211 and a lower disc 212 located below the upper disc, which are connected by a connecting rod 213. Wherein, the lower disc is positioned in a mounting hole 11 axially arranged at the upper part of the body 1. Meanwhile, a first return spring 23 is further disposed in the mounting hole, and the first return spring is fixedly connected to the lower bottom surface of the lower disk 212 and is used for supporting the bearing disk so that the bearing disk is in a standing state when not being pressed by external gravity. The support plate 22 is formed by assembling a plurality of support pieces 221. The whole supporting disk is of an umbrella-shaped structure, and a round hole is formed in the middle of the supporting disk to form an annular shape. The lower bottom surface of the support sheet is hinged with the upper end surface of the body through a pin shaft 24, so that the support sheet 221 can turn downwards under the action of gravity. Meanwhile, a clamping plate 222 is vertically and downwardly arranged at the edge of the inner ring of the supporting sheet 221, the clamping plate is in a long and thin strip shape, the end part of the lower end of the clamping plate is tightly propped against the side wall of the lower disk under the action of the gravity of the supporting sheet, and the lower disk plays a role of a clamping switch. In addition, in order to enable the clamping plates to smoothly turn over along with the supporting sheets after being separated from the constraint of the lower disc, a plurality of turning channels 2111 matched with each clamping plate are radially arranged on the upper disc.

As a further improvement of the above embodiment, a second return spring 25 is provided on the lower surface of the support piece 221, and the second return spring is pressed against the surface of the insulating shed in the body 1 after the support piece is turned to a certain position.

As a further modification of the above embodiment, the lower end surface of the chucking plate 222 on the side away from the lower disk 212 is a circular arc surface with a smooth circular arc transition.

The working principle is as follows: when the bird is in the utility model discloses on nest, its material of nesting produces the weight to the bearing dish, first reset spring compresses downwards under the effect of bird's nest this moment, and lower disc moves downwards thereupon. After the lower disc moves to a certain position, the clamping plate is separated from the support of the lower disc and overturns upwards under the action of the support plate. At this time, the supporting sheet is also turned downwards, so that the bottom of the bird nest is not supported by the supporting sheet consisting of the supporting sheet. The bird nest drops downwards along with the supporting sheet, and in the process again, the supporting sheet compresses the second return spring under the action of the gravity of the bird nest, so that after the bird nest breaks away from the action on the supporting sheet, the supporting sheet can rebound under the action of the second return spring, after the supporting sheet rebounds, the clamping plate overturns downwards along with the supporting sheet, and finally, the clamping plate is restored to the initial position under the action of inertia, and the lower disc realizes clamping and positioning the clamping plate again.
