Sealing device of collecting ring

Abstract

The invention discloses a sealing device of a collecting ring. The sealing device comprises a stator and a rotor, wherein an upper end cover and a lower end cover are respectively arranged at the upper end and the lower end of the stator; the rotor comprises a hollow rotating shaft, a rotating shaft sleeve, a lower rotor and an upper rotor; the lower rotor is connected with the upper rotor through a connecting piece of adjacent ends; the upper end cover is rotatably connected with the upper rotor through an upper bearing, and forms a water seal structure with the upper rotor through an upper oil seal; the lower end cover is rotatably connected with the rotor sleeve below the lower rotor through a lower bearing, and forms a water seal structure with the rotor sleeve below the lower bearing through a lower oil seal; a wiring trough which is used for laying rotor leads is arranged on the upper rotor along the axial direction; an upper sealing line plug is arranged between the wiring trough and the rotor leads; a lead outlet of a stator lead is formed on the lower end cover; and a lower sealing line plug is formed between the lead outlet and the stator lead. The sealing device of the collecting ring for music fountain is excellent in safety, convenient for repairing and maintenance, flexible to rotate, excellent in conductive effect, and long in service life.

Description

technical field [0001] The invention relates to an underwater sealing device, in particular to a sealing device for an underwater collector ring of a music fountain. Background technique [0002] In recent years, musical fountains have become popular in cities. The nozzle of the musical fountain can not only spray water, but also can rotate or swing to spray a variety of water column or water mist shapes. Since the electrical circuit of the music fountain is laid underwater, there are many links that need to be sealed, especially the collector ring that is responsible for the current transmission between the stator (stationary body) and the rotor (rotary body), its sealing, reliability, and flexible rotation. It directly determines the operational reliability and safety of the musical fountain. [0003] The underwater sealing collector ring of the existing music fountain includes: a conductive ring arranged on the rotor and rotating with the rotor, and a brush arranged on ...

AI Technical Summary

Problems solved by technology

There are some defects in the sealing of the collector ring with this structure: one is that the wires of the rotor are buried in the inner hole of the shaft as the water delivery channel, which is inconvenient for inspection and maintenance; the other is that the water and electricity are in the same way, which has potential safety hazard
