Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arresters, and in particular relates to a lightning arrester for a photovoltaic line. Background Art

[0002] Photovoltaic cable, referred to as "PV cable", is a special cable. It is one of the most important components of the solar panel system. PV cable consists of conductors, insulators and sheaths. Since PV cables are usually installed in extreme climates and environments, lightning arresters are required for protection.

[0003] However, most of the existing lightning arrester installation methods use nuts to lock the bottom of the lightning arrester and install it on the electric pole. The operation process is relatively cumbersome and it is not convenient to quickly install and fix the lightning arrester. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a lightning arrester for a photovoltaic line. When the lock tongue is disengaged from the fixing hole, the lock tongue is driven to reset under the action of the second spring rebound. The bottom end of the lock tongue is a plane, so the fixing seat is limited and fixed. The top seat is squeezed by the rebound of the first spring, and the arrester body is fixed by the squeezing of the fixing seat by the top seat and the limiting of the lock tongue, which is convenient for quick installation and fixation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightning arrester for a photovoltaic line, comprising a mounting seat and a lightning arrester body, the surface of the mounting seat is provided with four mounting holes, the bottom end of the lightning arrester body is provided with a fixing seat, the surface of the fixing seat is provided with a fixing hole, the top of the mounting seat is fixedly connected to a first spring, the end of the first spring away from the mounting seat is fixedly connected to a top seat, the top of the mounting seat is fixedly connected to two fixing columns, the surface of the fixing column is provided with a slide groove, the inside of the slide groove is fixedly connected to a second spring, one end of the second spring is fixedly connected to a locking tongue, the surface of the mounting seat is fixedly connected to a telescopic rod, the top of the telescopic rod is fixedly connected to a connecting plate, and one end of the connecting plate is movably connected to a pipe buckle.

[0006] Furthermore, a rubber pad is provided inside the tube buckle.

[0007] Furthermore, the locking tongue is slidably connected to the inside of the slide groove, the fixing column movably passes through the fixing hole, and the top end of the top seat is in contact with the bottom end of the fixing seat.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. Align the fixing column with the fixing hole on the surface of the fixing seat, and then press the arrester body. At this time, the fixing column moves in the fixing hole and contacts the lock tongue. One side of the lock tongue is an arc surface, so it will shrink into the inside of the slide groove and squeeze the second spring. At the same time, the bottom end of the fixed seat contacts the top of the top seat and drives the top seat to move downward to squeeze the first spring. When the lock tongue is out of the fixing hole, the lock tongue is reset by the rebound of the second spring. The bottom end of the lock tongue is a plane, so the fixed seat is limited and fixed. The top seat is squeezed by the rebound of the first spring. The arrester body is fixed by the squeezing of the fixed seat by the top seat and the limiting of the lock tongue, which is convenient for quick installation.

[0010] 2. Through the setting of the pipe buckle, the upper surface of the arrester body can be fixed with the pipe buckle. Through the setting of the rubber pad, it can play an insulating role. Fixing with the pipe buckle strengthens the installation firmness of the arrester body. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the bottom end of the fixing base contacts with the top end of the top base 7 and drives the top base 7 downward. The first spring 6 is moved to squeeze the first spring 6. When the lock tongue 11 is out of the fixing hole, the lock tongue 11 is reset by the rebound action of the second spring 10. The bottom end of the lock tongue 11 is a plane, so the fixing seat is limited and fixed. The top seat 7 is squeezed by the rebound action of the first spring 6. The arrester body is fixed by the squeezing of the fixing seat by the top seat 7 and the limiting of the lock tongue 11, which is convenient for quick installation. Through the setting of the pipe buckle 5, the pipe buckle 5 can be used to fix the upper surface of the arrester body 2. Through the setting of the rubber pad 12, it can play an insulating role. Fixing by the pipe buckle 5 strengthens the installation firmness of the arrester body 2.
