Underwater wireless collecting ring of fountain

Abstract

The invention discloses an underwater wireless collecting ring of a fountain. The underwater wireless collecting ring comprises a collecting ring rotor and electric slip ring. Water-sealed structuresare between the upper and lower ends of the metal collecting ring housing and a fountain rotating shaft. An input power line is electrically connected with the corresponding electric slip rings through an electric brush. A fountain control device is electrically connected to a signal input / output terminal of a modem A which is disposed on a fountain stationary body through a control signal line, and a signal input / output terminal of a modem B passes into the metal collecting ring housing in a sealed manner through the signal control line, and is electrically connected with a receiving / transmitting antenna which is arranged in the metal collecting ring housing. The modem A and the modem B are connected in a wireless communication manner through a transmitting / receiving antenna and the receiving / transmitting antenna. The underwater wireless collecting ring satisfies transmission of strong electricity, and satisfies stable transmission of weak electricity. The control signals between thefountains do not interfere, and the number of control lines can be easily expanded without increasing axial dimensions of the collecting ring.

Description

technical field [0001] The present invention relates to fountains, in particular to underwater wireless slip rings for fountains. Background technique [0002] The earliest artificial fountain was born in England in the mid-18th century. After a hundred years of development, it has become a well-known urban landscape. The existing fountains have been able to rotate, lift, and even dance with the rhythm of the music, spraying out various rich water shapes. Since the electrical circuit of the fountain is laid underwater, the collector ring responsible for the transmission of current between the stator (the stationary body of the fountain) and the rotor (the rotating body of the fountain) requires a reliable water seal and stable electrical conduction. [0003] Traditional collector rings are mainly composed of copper rings and carbon brushes pressed against the outer surface of the copper rings. The collector ring of this structure has the following defects: first, the struc...

AI Technical Summary

Problems solved by technology

The collector ring of this structure has the following defects: first, the structure is complex, the carbon brush needs to be installed in the carbon brush sleeve, and the spring top pressure is required; second, the wear is fast, and the carbon brush needs to be replaced frequently; third, there are hidden dangers, Toner powder generated by brush wear can easily cause short circuits

[0007] Over the years, these defects of underwater slip rings have always been technical problems that those skilled in the art want to solve, but there has been no breakthrough
