High-altitude collector ring

Abstract

The invention discloses a high-altitude collector ring which comprises an inner ring, an outer ring, a power ring and a lightning discharge ring. The inner ring is axially and radially positioned through a deep groove ball bearing and via the outer ring, the inner ring is in sliding connection with the outer ring through a thrust cylindrical roller bearing, and an optical fiber rotating joint is arranged at the top of the inner ring. The middle part of the optical fiber rotary joint is connected with a middle end cover through a bolt, the bottom of the optical fiber rotary joint is rotationally connected with a middle baffle plate in a pulling and inserting manner, and a power ring electric brush welding wire penetrates through the middle end cover and is connected to a device base and thephotoelectric connector. According to the invention, the size of a product is reduced, the weight of the product is reduced, the maintainability of the product is realized, the lightning stroke resistance of the product is improved, the normal operation of the product after lightning stroke is ensured, the service life of the product is prolonged, and the working intensity of the product in a severe environment is increased.

Description

technical field [0001] The invention relates to the technical field of collector rings, in particular to a high-altitude collector ring. Background technique [0002] An aerostat is an aircraft whose density is lighter than air and which relies on atmospheric buoyancy to lift into the air. As a general-purpose platform, modern aerostats can be equipped with a variety of equipment to monitor ground conditions in a 360-degree manner. They have a wide range of uses, including early warning radar, electronic countermeasures, electronic jamming, video surveillance, smog detection, relay communication and imaging. Equipment, etc., which are widely used in early warning detection, ground observation, reconnaissance and countermeasures, communication relay, security monitoring, environmental monitoring and other fields. The aerostat is connected to the ground vehicle through a cable, and the aerostat and the cable are connected through a slip ring. The outer ring of the slip ring i...

AI Technical Summary

Problems solved by technology

[0003] 1. In order to realize high-voltage power transmission and meet lightning discharge requirements, the high-altitude slip ring of the aerostat developed in the early stage has large dimensions and heavy weight, resulting in a large volume of the entire high-altitude system, which affects the lift-off height

[0004] 2. In order to ensure the tensile strength of the high-altitude slip ring of the early aerostat, the shell is integrated, and the joints are mostly welded, which is poor in maintainability

[0005] 3. The anti-lightning voltage of the early aerostat high-altitude slip ring can only withstand 10KV, and after the lightning test, the product performance drops or even fails, and it cannot continue to be used normally
