Description

Technical Field

[0001] The invention belongs to the technical field of electrical support, and in particular relates to an insulator on which a device capable of reducing dust accumulation is installed. Background Art

[0002] Insulators are devices installed between conductors at different potentials or between conductors and ground potential components. They can withstand voltage and mechanical stress and are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into high-type high-voltage power line connection towers with many disc-shaped insulators hung at one end. They are designed to increase the creepage distance and are usually made of glass or ceramics and are called insulators.

[0003] When the existing insulator is used, dust adheres to the surface of the insulator, and the cleaning effect of the dust is poor, which makes the insulator unstable during operation, thereby reducing the working efficiency of the insulator. Summary of the invention

[0004] The object of the present invention is to provide an insulator with an automatic cleaning function, which utilizes the rotational movement of a rotating rod installed in the insulator to drive an umbrella scraper to scrape away dust adhered to an insulating umbrella cover, thereby preventing the insulator from failing due to flashover caused by excessive dust accumulation on the surface of the insulating umbrella cover.

[0005] The technical solution of the present invention is to provide an insulator with automatic cleaning function, comprising an insulating rod and a plurality of insulating umbrella sleeves, wherein the insulating umbrella sleeves are fixedly installed on the insulating rod, and characterized in that the insulating rod is provided with a rod cavity and an umbrella scraper movable hole, the top surface and the bottom surface of the insulating umbrella sleeve are both provided with umbrella sleeve ring grooves, an umbrella scraper is installed between the umbrella sleeve ring grooves of the insulating umbrella sleeves adjacent to each other, an umbrella scraper is provided at one end of the umbrella scraper with an umbrella scraper fulcrum, an umbrella scraper push rod is movably installed at the other end of the umbrella scraper, the umbrella scraper fulcrum is placed in the umbrella sleeve ring groove, a rotating rod and a rotating rod motor are installed in the rod cavity, a rotating rod is fixedly provided with a rotating disk and a rotating rod swing rod, the rotating disk is provided with an umbrella scraper push groove, the umbrella scraper push rod passes through the umbrella scraper movable hole and is movably installed in the umbrella scraper push groove, a rotating shaft of the rotating rod motor is fixedly provided with a motor swing rod, and the motor swing rod is movably connected to the rotating rod swing rod.

[0006] The umbrella scraper of the present invention is closely attached to the outer surface of the insulating umbrella cover, and the movement track of the umbrella scraper push rod matches the surface shape of the insulating umbrella cover.

[0007] The motor rocker is movably connected to the rotating rod rocker, wherein the rotating rod rocker is provided with a rocker movable hole, the motor rocker is installed in the rocker movable hole, and the motor rocker can move back and forth in the rocker movable hole, thereby forming a crank structure between the rotating shaft of the rotating rod motor and the rotating rod. One rotation of the rotating rod motor can drive the rotating rod to first make a 60° clockwise swing, and then a 60° counterclockwise swing, completing one circle of automatic cleaning process.

[0008] There are 8 umbrella scrapers evenly distributed on the surface of an insulating umbrella cover, that is, a 45° angle is formed between each umbrella scraper. An umbrella scraper groove is opened on the surface of the umbrella scraper facing the insulating umbrella cover, and a strip scraper or a strip brush can be installed in the groove of the umbrella scraper groove.

[0009] Preferably, the umbrella scraper push rod is provided with a push rod pin, and the push rod pin is movably mounted on the umbrella scraper push groove. The umbrella scraper push rod is provided with a push rod pin, and the push rod pin is placed in the umbrella scraper push groove, and the push rod pin is perpendicular to the groove direction of the umbrella scraper push groove. When the surface of the insulating umbrella cover is a horizontal plane, the push rod pin is perpendicular to the movement trajectory of the umbrella scraper push rod; when the surface of the insulating umbrella cover is an inclined plane, the push rod pin is not perpendicular to the movement trajectory of the umbrella scraper push rod.

[0011] Preferably, the insulating rod is also equipped with a bird repeller, which may be an ultrasonic bird repeller or a sound source intelligent bird repeller that simulates the sound of an eagle or a shotgun to drive away birds, in order to keep birds away from insulators and prevent bird droppings from falling onto insulators and affecting the insulating properties of the insulators.

[0012] Preferably, the inner side of the insulating umbrella cover is provided with an umbrella cover cavity, and the umbrella cover cavity is provided with an umbrella cover heating wire. A heating device is provided in the rod cavity, and the heating device is electrically connected to the heating wire, so that when necessary, the outer surface of the insulating umbrella cover can be heated by the heating wire to obtain a higher temperature, so that it is difficult for moisture attached to the outer surface of the insulating umbrella cover to condense and adhere to it, thereby preventing dust floating in the air from adhering to the insulating umbrella cover in a humid climate, that is, the heating effect of the heating wire in the insulating umbrella cover can greatly reduce the situation where dust adheres to the insulating umbrella cover, thereby further preventing the insulator from flashing over.

[0013] Compared with the prior art, the insulator of the present invention can open the scraper installed between the insulating umbrella sleeves to scrape away the dust when needed, ensuring that the insulator will not fail due to flashover caused by excessive dust in the insulating umbrella sleeve.

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The drawings constituting a part of the present application are used to provide a further understanding of the present invention, and the exemplary embodiments of the present invention and their description are used to explain the present invention, and do not constitute an improper limitation of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0019] Reference Figure 1 , Figure 2 An insulator with automatic cleaning function of the present invention comprises an insulating rod 1 and a plurality of insulating umbrella sleeves 2, wherein the insulating umbrella sleeves 2 are fixedly mounted on the insulating rod 1, and characterized in that the insulating rod 1 is provided with a rod cavity 11 and an umbrella scraper activity hole 12, the top and bottom surfaces of the insulating umbrella sleeve 2 are both provided with umbrella sleeve ring grooves 21, and umbrella scrapers 3 are installed between the umbrella sleeve ring grooves 21 of the insulating umbrella sleeves 2 adjacent to each other, and one end of the umbrella scraper 3 is provided with an umbrella scraper fulcrum 31, and the other end of the umbrella scraper 3 is provided with an umbrella scraper fulcrum 31. An umbrella scraper push rod 32 is movably installed, the umbrella scraper fulcrum 31 is placed in the umbrella sleeve ring groove 21, the rod cavity 11 is installed with a rotating rod 4 and a rotating rod motor 5, the rotating rod 4 is fixedly installed with a turntable 41 and a rotating rod swing rod 42, the turntable 41 is provided with an umbrella scraper push groove 43, the umbrella scraper push rod 32 passes through the umbrella scraper movable hole 12 and is movably installed in the umbrella scraper push groove 43, the rotating shaft of the rotating rod motor 5 is fixedly installed with a motor swing rod 52, and the motor swing rod 52 is movably connected with the rotating rod swing rod 42.

[0020] When the present invention is in a normal state, the umbrella scraper 3 is accommodated in the umbrella sleeve ring groove 21 and slightly protrudes out of the umbrella sleeve ring groove 21, the scraper strip on the umbrella scraper 3 is located outside the umbrella sleeve ring groove 21 and is close to the surface of the insulating umbrella sleeve 2, the push rod pin on the umbrella scraper push rod 32 is located at the innermost side of the umbrella scraper push groove 43, and the motor rocker 52 is at a 90° angle with the rotating rod rocker 42.

[0021] When the insulator is required to automatically clean the dust on the insulating umbrella cover 2, the worker can start the rotating rod motor 5 through electrical connection or signal connection. The rotating shaft on the rotating rod motor 5 rotates, allowing the motor swing rod 52 at the three o'clock position to rotate clockwise to the six o'clock position, driving the rotating rod swing rod 42 to move. The angle between the motor swing rod 52 and the rotating rod swing rod 42 gradually decreases to 0°. The movement of the rotating rod swing rod 42 drives the turntable 41 to rotate clockwise. The rotation of the turntable 41 pushes the push rod pin from the innermost side of the umbrella scraper push groove 43 to the outermost side of the umbrella scraper push groove 43, so that the umbrella scraper push rod 32 can push the umbrella scraper 3 outward to the swing direction of the umbrella scraper 3 across the inner and outer circles of the insulating umbrella cover 2.

[0022] Then the motor swing rod 52 continues to rotate clockwise to the 9 o'clock direction, driving the rotating rod swing rod 42 to continue to swing clockwise, and at this time, the angle between the motor swing rod 52 and the rotating rod swing rod 42 gradually increases from 0°. The movement of the rotating rod swing rod 42 drives the rotating disk 41 to continue to rotate clockwise, so that the push rod pin at the outermost side of the umbrella scraper push groove 43 is pushed clockwise by the umbrella scraper push groove 43. Because the umbrella scraper fulcrum 31 can move on the umbrella sleeve ring groove 21, the rotation of the rotating disk 41 pushes the umbrella scraper 3 clockwise to a certain angle through the umbrella scraper push rod 32, thereby allowing the umbrella scraper 3 to rotate relative to the insulating umbrella sleeve 2, so that the umbrella scraper 3 can scrape away the dust attached to the insulating umbrella sleeve 2.

[0023] Then, the motor swing rod 52 continues to rotate clockwise to the twelve o'clock direction, and the angle between the motor swing rod 52 and the rotating rod swing rod 42 continues to increase to 180°. At this time, the rotating rod swing rod 42 is pushed back by the motor swing rod 52 to rotate counterclockwise, driving the turntable 41 to rotate counterclockwise, so that the umbrella scraper push groove 43 provided on the turntable 41 rotates counterclockwise, and the push rod pin shaft installed on the umbrella scraper push groove 43 is pushed back to the innermost side from the outermost side of the umbrella scraper push groove 43, pulling the umbrella scraper push rod 32 inward, thereby retracting the umbrella scraper 3 inwardly to the umbrella sleeve ring groove 21.

[0024] Finally, the motor rocker 52 continues to rotate clockwise to the three o'clock direction, pushing the rotating rod rocker 42 to rotate counterclockwise, so that the push rod pin installed on the umbrella scraper push groove 43 is pushed counterclockwise, and the pushing movement of the push rod pin pushes the umbrella scraper 3 back counterclockwise along the track of the umbrella sleeve ring groove 21 through the umbrella scraper push rod 32, completing an automatic cleaning process and waiting for the next automatic cleaning process.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
