Problems solved by technology

Although the patent with the authorized notification number CN2897448Y discloses a "Numerical Control Nozzle for Musical Fountain", a planetary gear reducer is used, but the motor shaft and the nozzle rotation axis are transmitted to the lead screw through a belt, and the lead screw drives The crankshaft transmits the torque, and the crankshaft drives the nozzle to rotate. Not only the structure is more complicated, but also the friction is large and the transmission efficiency loss is large.
After the existing worm gear meshes, the torque is mainly transmitted by the friction of the tooth surface. This method not only reduces the output efficiency of the reducer, but also produces a gap between the teeth due to friction. The gap expands with the continuous output of the reducer torque, causing the motor to reverse rotation or When reciprocating rotation, the worm gear of the reducer cannot be meshed in time, causing the output of the reducer to be out of sync with the motor, which affects the accuracy of torque transmission and the consistency between the arrangement and the action of the fountain; Vertical direction and external meshing, not only the external dimension is large, but also the entrance of the motor and the reducer needs to be sealed in two directions, and the processing and installation of the required sealing parts are more cumbersome; in addition, the existing worm gear Aluminum is prone to corrosion in water, especially the corrosion of the input and output ports seriously affects its installation and disassembly and its waterproof sealing performance. However, the existing related numerical control fountain equipment technology has not been reported on the external seal of the reducer.

Abstract

The invention relates to a novel underwater numerical control nozzle. The novel underwater numerical control nozzle comprises a motor, wherein the motor is fixedly connected with a planet gear speed reducer; an output end of the planet gear speed reducer is connected with a first input end of a connecting disc; an output end of the connecting disc is connected with a first port of a three-way joint; a transmission shaft is inserted in the three-way joint; and an output end of the transmission shaft is fixedly connected to the center of a water passing support ring, and an input end is connected with an output shaft of the planet gear speed reducer through a coupling. A first port of the three-way joint and the transmission shaft realize sealing connection through a rubber sealing ring and a skeleton sealing ring. A waterproof sealing cover is arranged outside the planet gear speed reducer. The transmission shaft is axially positioned through a bearing and a hoop. The novel underwater numerical control nozzle is high in transmission efficiency, small in equipment volume, low in cost, excellent in waterproof sealing performance and widely applied to various fountain devices.

Description

technical field [0001] The invention relates to a new type of underwater numerically controlled sprinkler head, in particular to a new type of underwater numerically controlled sprinkler head which combines a planetary gear reducer with a motor and simultaneously waterproofs and seals the planetary gear reducer and the motor. Background technique [0002] At present, most of the existing numerical control fountain equipments are connected with the motor by worm gear reducer. For example, a patent with the authorized announcement number CN2724853Y discloses a "Numerical Control Waterscape Performance Device with Pre-editing Function", and a patent with the authorized announcement number CN101628267A Disclosed is a "numerical control waterscape sprinkler". Although the patent with the authorized notification number CN2897448Y discloses a "Numerical Control Nozzle for Musical Fountain", a planetary gear reducer is used, but the motor shaft and the nozzle rotation axis are trans...
