A portable telescopic lightning protection device

Abstract

The invention discloses a portable retractable lightning protection device. The device comprises a first retractable rod, a second retractable rod and a third retractable rod; the first retractable rod and the second retractable rod are both hollow pipes, the second retractable rod is slidingly matched in the first retractable rod, and the upper end of the first retractable rod is provided with asliding hole matched with the second retractable rod. The device is simple and reasonable in structure; when the device is fixed, the retractable rods are vertically placed on a smooth plane, then movable fixing rods are flat laid on the plane, piston rods are pulled through handles and drive piston blocks to slide outwards, in this way, negative pressure can be generated in each piston cavity, and therefore suction cups are fixed on the plane; the suction cup fixing mode is achieved on the basis that a vehicle body is provided with a smooth surface, more convenience is provided for the fixation of the device accordingly, and the device is also convenient to carry in the later period and high in practicality.

Description

technical field The invention relates to the technical field of lightning protection equipment, in particular to a portable telescopic lightning protection device. Background technique Vehicles that carry out long-distance transportation in harsh thunderstorm weather environments are vulnerable to lightning attacks, especially transport convoys equipped with military equipment or ammunition, which are very dangerous when encountering such lightning weather. Yet present transport vehicle comprises army transport vehicle, still does not have the device system that avoids lightning attack, prevents lightning disaster. If the mobile communication vehicle is directly parked in the open field without any other building protection, the mobile communication vehicle at this time is equivalent to a fixed communication base station, and will suffer from direct lightning, induction lightning, lightning wave intrusion and ground potential counterattack, etc. harm. Therefore, some vehic...

AI Technical Summary

Problems solved by technology

Therefore, some vehicle-mounted lightning protection device systems have appeared, which are generally composed of vehicle-mounted lightning rods and grounding devices. Because the installation height of the lightning rod is fixed and does not have a telescopic function, the height of the lightning rod and the scope of lightning protection cannot be adjusted. The best lightning protection effect, the lightning protection effect is average

Therefore, a vehicle-mounted manual retractable lightning rod is needed to solve the problem that the height of the lightning rod of the existing vehicle-mounted lightning protection device cannot be adjusted
