AI Technical Summary

Technical Problem

After long-term use, the existing photovoltaic grid-connected devices are affected by high-intensity light in the photovoltaic station environment, and the elastic force of the hook claws decreases, resulting in unstable connection.

Method used

A high-efficiency distributed photovoltaic power station convergence grid connection device is designed, using a clamping mechanism between a scraper and a contact plate. The sliding block is driven upwards along the slide chute by rotating the plate. The scraper is embedded in the wire strip to prevent the wire from moving outward and ensure stable connection.

Benefits of technology

It effectively avoids the problem of slackness after long-term use, improves the stability of equipment connection, and ensures the safe and stable operation of photovoltaic power stations.

Abstract

The invention discloses a high-efficiency distributed photovoltaic power station confluence and grid connection device and a use method thereof.The device comprises a shell, a fixing box is connected to the side wall of the shell in a penetrating mode, an input wire is arranged on the inner wall of the fixing box, and after a worker inserts the input wire into the shell by a sufficient depth, the input wire is pulled out by a certain distance, and then the input wire is connected with the shell; at the moment, a scraper is influenced by the inclination angle of the scraper and moves outwards along with the input electric wire, the scraper drives a sliding block to slide upwards along the inner wall of a sliding groove through a rotating plate, the rotating plate forces one end of a first telescopic rod to tilt upwards through a rotating frame, and the tilted end of the first telescopic rod forces a fixed rod to swing downwards with the rotating rod as the center point; the fixing rod swinging downwards drives the sliding plate to slide downwards along the inner wall of the first sliding rail, the moving sliding plate drives the contact plate to be tightly attached to the outer wall of the copper wire of the input wire, power connection is completed, and the contact plate is forced to be tightly attached to the copper wire of the input wire.
