The invention discloses an electrically controlled rotating joint which comprises a housing, a small gear and a water spraying port. The left side of the housing is connected with a cable, a non-rotatable pipe is arranged above the cable, the inside of the housing is connected with a motor fixing bolt, the right side of a motor is connected with a speed reducer, the right side of the housing is connected with a rotatable pipe, the right side of the rotatable pipe is in sealed connection with a spray head, an oil damping structure is arranged in the housing, the small gear is installed on the right side of the speed reducer and is meshed with a large gear, a high-pressure water inlet is formed in the left side of the non-rotatable pipe, the right side of the non-rotatable pipe is in sealed connection with a seal element, and the water spraying port is connected with the spray head. A dip angle of the water spraying port on the spray head of the electrically controlled rotating joint is omitted, the rotating speed of the spray head is controlled by adopting the speed-adjustable motor and the gear set, an ideal cleaning effect can be obtained when appropriate rotating speed is selected, and the phenomenon that the service life of the seal element is affected by larger rotating speed is avoided.
Description
technical field [0001] The invention relates to the technical field of high-pressure water jet cleaning, in particular to an electronically controlled rotary joint. Background technique [0002] At present, when the known high-pressure water jet is used for cleaning construction, the cleaning nozzle needs to be rotated according to the situation. The rotation speed has different requirements due to different working conditions. This rotation is currently powered by the reaction force generated by the high-pressure water ejected from the nozzle. , the resistance generated by the oil damping structure in the rotary joint is completed together. The sprayed water column is designed to have an inclination angle relative to the normal line of the nozzle body. The inclination angle affects the size of the reaction force, and the flow and velocity of the water column also affect the reaction force. Size, these factors all affect the rotation speed of the nozzle, the inclination angl...
