Abstract

The invention belongs to the technical field of power distribution equipment, in particular to a rotatable dustproof insulator. The problem that dust and rainwater accumulated at the joint of an insulator and a line are difficult to remove is solved. The insulator includes a base, a fixing block is fixedly connected to the middle of the top end of the base. The outer wall of the fixing block is sleeved with a rotating sleeve. The top end of the fixing block is fixedly connected with a reciprocating screw rod; the reciprocating lead screw is sleeved with a rotating block, the bottom end of therotating block is fixedly connected with a rubber plate, the rubber plate is slidably connected with the inner wall of a rotating sleeve, a first through hole is formed in the top end of the rotatingsleeve, the rotating sleeve is rotatably connected with a connecting sleeve at the first through hole, and the top end of the connecting sleeve is fixedly connected with a fixing disc. The rotating sleeve rotates to drive the rubber plate to move up and down to do piston motion, so that an air blowing effect can be achieved, dust and rainwater at the position where a circuit and the device are fixed can be blown away, and a better effect is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a rotatable dustproof insulator. Background technique [0002] At present, the insulators of high-voltage overhead lines in the power grid are divided into two types: pillar type and suspension type, which play the role of fixing and insulating the line. Now, the measures to improve the anti-flashover ability of insulators are mainly from the three aspects of insulator materials, cleaning, and hydrophobic coatings. , It needs to consume a lot of manpower, material resources and financial resources. The existing insulators have weak waterproof and dustproof capabilities, especially the connection between lines and insulators, which affects the safety of power transmission of cables. [0003] After searching, the Chinese patent application number is 201310252803.1, which discloses a rotary three-proof insulator, including a fixed handle, a suspension shaft, an ...
