Multi-angle lightning rod capable of discharging in advance

Abstract

The invention provides a multi-angle lightning rod capable of discharging in advance. A support rod and a protective cover are arranged on a pedestal, the top end of the protective cover is hinged toa top cover, and the internal of the protective cover is divided into an upper cavity and a lower cavity by a separator plate; the upper end of the support rod is connected with a first slide bar, andthe upper end of the first slide bar is provided with a first contact end; the upper cavity is internally provided with a second slide bar, and the lower end of the second slide bar is provided witha second contact end; the top end of the second slide bar is provided with a metal sphere, the top of the metal sphere is provided with an auxiliary rod, and the upper end of the auxiliary rod is provided with first, second and third lightning rods; the surface of the metal sphere is provided with multiple rod bodies, and the end portion of each rod body is provided with a spherical rod head; theupper end of the upper cavity is provided with an emitter, the inner wall of the emitter is provided with electrodes, the external lower end of the emitter is provided with an accelerator, and an annular plate is arranged over the accelerator; the lower end of the second slide bar is provided with an insulated tooth plate, the lower cavity is internally provided with a driving motor, and an outputshaft is provided with an insulated gear which is engaged with the insulated tooth plate; the end, hinged to the protective cover, of the top cover is provided with a pull column, the pull column isconnected with a stay rope, and the stay rope is connected to an output shaft of a driving motor through a steering wheel group; and a voltage stabilizer and an advanced discharging device are arranged on the support rod. Thus, a lightning effect can be improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of lightning rods, in particular to an early discharge multi-angle lightning rod. Background technique [0002] Lightning rods, also known as lightning rods, lightning rods, lightning arresters, and lightning rods, are devices used to protect buildings, tall trees, etc. from lightning strikes. When a thundercloud discharge approaches the ground, it distorts the ground electric field. At the top of the lightning rod, a space where the local electric field is concentrated is formed to influence the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then introduce the lightning current into the earth through the grounding down conductor and the grounding device, so that the protected object is not struck by lightning. . [0003] But the present lightning rod is only a single lightning rod, and the lightning effect is not obvious. In order to mor...
