Adjustable high-voltage grounding wire utilizing ratchet wheel positioning principle

Abstract

The invention relates to the technical field of power. The invention further discloses an adjustable high-voltage grounding wire using the ratchet wheel positioning principle. Insulating rod, a vertical push rod is connected into the insulating rod in a sliding manner; a fixed block is fixedly connected to the outer part of the vertical push rod; a first spring is fixedly connected to the outer part of the fixed block; the top of the vertical push rod is fixedly connected with a mounting plate; the top of the mounting plate is fixedly connected with a lower pressing plate; a threaded rod is connected into the mounting plate in a sliding manner; the top of the threaded rod is fixedly connected with a pressing block; the outer part of the threaded rod is in threaded connection with an adjusting ring; through cooperative use of the vertical push rod, the adjusting gear and the vertical toothed rod, the vertical push rod can move upwards and clamp a wire by pulling the vertical toothed rod, operation is convenient, use is easy, quick lifting of the lower pressing plate can be guaranteed. Meanwhile, the lifting stability of the lower pressing plate is guaranteed, the clamping efficiencyis improved, and the trouble of unceasingly screwing an insulating rod is avoided.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an adjustable high-voltage grounding wire utilizing the ratchet positioning principle. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. The primary energy of the system is converted into electricity through mechanical energy devices, and then the ele...

Problems solved by technology

[0003] The current grounding wires usually use double-tongue hook-type clamps and bolt-type clamps. The structure of the double-tongue hook-type clamps is an inverted U-shaped structure, which is fixed on the wire by clamping. The fixing method is not reliable and easy Falling off, when installing vertical wires, its installation and disassembly are more difficult, because the hook is not secure and it is easy to fall off, which brings great difficulties to the grounding work of vertical high-voltage wires, resulting in the use of double-tongue hook type wire clips The range is small, the use efficiency is low, and the fixation is not firm, there is a certain danger

[0004] The bolt-type wire clamp relies on the rotation of the insulating handle to clamp and loosen the wire. When installing and dismounting, the insulating handle can only be rotated continuously to clamp the wire. The operation is very troublesome, time-consuming and laborious. Due to different operators, the rotating The strength cannot guarantee the clamping of the wires, and the wires are easy to fall off, which brings a certain degree of danger to high-voltage work. In addition, the existing clamps often use a straight plate clamping method for the upper and lower pressure plates. Due to their physical characteristics, resulting in There are certain defects in the clamping method
