Technical Field

[0001] This utility model relates to the field of chimney lightning protection, and in particular to a connection device for a lightning rod at the top of a fiberglass inner cylinder chimney. Background Technology

[0002] Fiberglass (also known as glass fiber reinforced plastic) is a composite material with synthetic resins (such as unsaturated polyester, epoxy resin, and phenolic resin) as the matrix material and glass fiber and its products (cloth, tape, felt, etc.) as the reinforcing material. It is an insulating material and does not conduct electricity.

[0003] For sleeve chimneys with fiberglass inner cylinders, the lightning rod needs to be anchored to the metal area below the top ring plate of the outer cylinder to conduct lightning due to the liquid collection device, fiberglass flange, and sliding space for the installation of the inner and outer cylinders. At the same time, considering the lightning protection effect, the lightning rod also needs to extend a certain height out of the cylinder to meet the lightning protection design specifications. This results in the fixing point of the lightning rod being relatively low compared to the height, and the installation structure being unstable.
