Multi-layer grounding protection device and operation system thereof

Abstract

The invention relates to the technical field of grounding protection, in particular to a multi-layer grounding protection device and an operation system thereof, which comprises a first protection layer, a second protection layer and a third protection layer which are sequentially stacked from top to bottom, the volume of the first protection layer, the volume of the second protection layer and the volume of the third protection layer are sequentially reduced, the first protection layer is composed of a base frame and an extension part, connecting pieces are arranged at the four corners of the top end of the base frame, the extension part is fixedly connected with the base frame through the connecting pieces, the base frame is composed of a plurality of metal rods, and the metal rods are fixedly connected with the base frame. The first protection layer is connected with the second protection layer through a first clamping ring, the second protection layer is connected with the third protection layer through a second clamping ring, and the stacked protection layers can better protect internal devices through the Faraday cage electrostatic shielding effect.

Description

Technical field [0001] The present invention relates to the field of earth protection technology, in particular to a multilayer earth protection device and a computing system thereof. Background [0002] Grounding can be divided into protective grounding, lightning protection grounding, shielding grounding and anti-static grounding, etc., which can prevent people from being subjected to electric shock, prevent equipment and lines from being damaged, prevent fire and prevent lightning strikes, etc., is an effective security protection measure, a wide range of applications, mobile communication technology in the field, the normal operation of the antenna feeder system can not only reduce blind spots, improve coverage, but also reduce interference, string calls, reduce call rate, improve network service quality. In order to ensure the operating quality of the antenna feeder system, the antenna feeder is usually grounded, in the prior art, the connection between the feeder and the gr...

Problems solved by technology

However, when using waterproof cement and adhesive tape to seal and protect the connection, it has the disadvantages of complicated installation, long installation time, and unsatisfactory sealing effect

In order to avoid the problems caused by the use of waterproof cement and adhesive tape, Chinese patent CN202189876U discloses an antenna-feeder grounding protection box that is easy to install, waterproof, impact-proof, and corrosion-resistant, and can ensure the direction of outgoing lines. In the protective box, a gel sealing strip is installed in the protective box to protect the connection, but the structure of the grounding protection box for the above-mentioned antenna and feeder is relatively complicated, the size is large, and it cannot be used for feeders of various sizes, and the application range is narrow.
