A rotary connection structure of anti-frost fan

Abstract

The invention discloses a swivel connection structure of an anti-frost fan, which comprises a circular insulating disc and a rotating flat plate. An intubation tube is formed on the insulating disc, and a mandrel is plugged and fixed on the insulating disc, and the upper end of the mandrel passes through the rotating flat plate. The socket is fixed with gears; the inner carbon brush ring and the outer carbon brush ring are plugged and fixed on the upper end of the insulating disc, and the upper ends of the inner carbon brush ring and the outer carbon brush ring are exposed from the upper end of the insulating disc, and the insulation inside the intubation tube The lower end surface of the disc is formed with a cable jack that runs through the upper end of the insulating disc, and the insulating discs on the lower side of the inner carbon brush ring and the outer carbon brush ring are respectively formed with a first slot and a second slot connected to the cable jack. ; The rotating flat plate is plugged and fixed with a power connection seat, the power connection seat is composed of a T-shaped insulating seat and two elastic conductive contacts, and the two elastic conductive contacts on the power connection seat elastically lean against the inside respectively carbon brush ring and outer carbon brush ring.

Description

technical field [0001] The invention relates to the technical field of fans, and more specifically relates to a swivel connection structure of an anti-frost fan. Background technique [0002] In early spring and late autumn, due to the intrusion of cold air, the temperature drops, especially in clear and windless nights and early mornings, when radiation heat dissipation increases on some hillsides, the ground temperature drops rapidly. At the same time, plants planted on the ground, if trees, Tea trees also cool down rapidly, and when the surface temperature of the plants drops below 0°C, they will suffer from frost damage. If the tree’s frost damage affects the quality and yield of the fruit produced by the fruit tree; if the tea tree frost damage directly causes the tea leaves to freeze to death and wither, Seriously affect the yield of tea. Thereby people think of erecting a column on the ground, install a fan on the top of the column, send the relatively warm air from ...

AI Technical Summary

Problems solved by technology

[0003] Present anti-frost fans are generally provided with a high place, and can realize rotary operation, but the cables for connecting the rotating motor and the anti-frost fan are generally all arranged on the outside of the column, and the electrical connection structure of the rotating motor and the anti-frost fan is also Exposed to the outside world, and anti-frost fans are generally installed outdoors, the exposed cables and exposed electrical connection structures pose potential safety hazards
