Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection equipment, in particular to a pre-discharge lightning rod. Background Art

[0002] Pre-discharge lightning rod, also known as early discharge lightning rod, is a kind of lightning rod that can quickly transfer lightning current to the earth in advance, so as to ensure the safety of buildings and personnel. When the existing pre-discharge lightning rod is installed and used, it is basically connected to the grounding steel bar by welding, which is not convenient for later disassembly and replacement. In addition, a lightning counter needs to be installed when the pre-discharge lightning rod is used. At present, the installation process of the lightning counter is relatively cumbersome, and the installation and disassembly efficiency is not high, which affects the speed of later maintenance. Therefore, we have introduced a new pre-discharge lightning rod. Utility Model Content

[0013] 1. Install the two arc plates on the outer surface of the lightning rod body through hinges. During installation, align the fixing block and install it in the fixing groove, and use the elastic force of the two springs inside the fixing block to shrink and reset, so that the two protrusions can be quickly clamped in the two clamping holes.

By rotating the two first turning handles respectively, the two first clamping plates are driven away from the outer surface of the lightning rod body, and then by squeezing the two protrusions at the same time, the internal springs are squeezed and contracted due to the action of force, so that the two protrusions are separated from the two clamping holes, so that the two arc plates can be quickly opened, and the lightning strike counter can be quickly disassembled, making the installation and disassembly efficiency more efficient and convenient for later disassembly and maintenance;
