Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] The invention provides a lightning protection device, such as figure 1 As shown, it includes a disc-shaped base 1, the base 1 is made of metal material, and is fixed below the ground by anchor bolts. The needle joint assembly 2 is arranged on the base 1 , and the needle joint assembly 2 is perpendicular to the center position connected to the base 1 .

[0033] Such as figure 1 with figure 2 As shown, the needle section assembly 2 includes, from bottom to top, a first-level needle section 21, a second-level needle section 22, a third-level needle section 23, a fourth-level needle section 24, and a fifth-level needle section 25, which are made of metal materials. The needle sections 21, the second-level needle sections 22, the third-level ...

Abstract

The invention discloses a lightning protection device. The device comprises a base fixed under the ground and a pin joint assembly connected with the base; the pin joint assembly comprises two or morecylindrical conductors, upper limiting components, and limiting assemblies; the cylindrical conductors are sleeved with one another sequentially; the upper limiting components are fixedly with one end of each conductor and abut against the end surface of the conductor when the conductors move relatively along an axial direction; the limiting assemblies are connected with the ends of the conductors and can abut against each other to prevent the detachment of the conductors along an axial direction when the conductors are separated from each other, wherein the ends of the conductors are sleevedwith one each other; two ends of the pin joint assembly are closed; and the inner cavity of the pin joint assembly is communicated with an air pump through a through hole. The installation of the lightning protection device of the invention is relatively labor-saving.

Description

technical field [0001] The invention relates to the technical field of lightning protection devices, in particular to a line lightning protection device. Background technique [0002] Lightning protection devices are used to guide lightning to the ground to prevent buildings or people from being shocked. The lightning protection device includes a lightning rod, which is usually made of metal material, relatively long in length and heavy in weight, and needs to be erected and fixed on the ground during installation. For example, the Chinese patent whose notification number is CN204858272U discloses a lightning rod, including a base, a sleeve, a ground electrode and a needle body, the ground electrode and the sleeve are located on the base, the bottom of the needle body is located in the sleeve, and the needle body includes at least Two detachably connected needle sections, the base and the sleeve are made of conductive materials; when installing, first fix the base and the s...
