Two-dimension fountain device

Abstract

The invention relates to a two-dimension fountain device, which comprises a lower dimension mechanism and an upper dimension mechanism. The lower dimension mechanism and the upper dimension mechanism respectively comprise a motor, a speed reducer, an output shaft, a three-way connector and an overflow support ring. The upper dimension mechanism also comprises a shower nozzle with an elbow pipe. In the lower dimension mechanism, an outlet at the lower end of the shell of the speed reducer is connected with a water-proof tube; the bottom part of the water-proof tube is provided with a cable input connector; the outer wall of the lower end of the output shaft in the water-proof tube is connected with a nut; the inner wall of the lower end of the output shaft in the water-proof tube is connected with a conducting ring seat; and the bottom part of the conducting ring seat is connected with an axial conducting ring inserted into the conducting ring seat. The first ports of the two three-way connectors and the outlet of the shell of the corresponding speed reducer as well as the corresponding input shaft are respectively and hermetically connected through two rubber seal rings, a skeleton seal ring, a seal stop bowl and a stainless steel snap ring. The third ports of the two three-way connectors and the corresponding overflow support ring are hermetically connected through a polytetrafluoroethylene ring. The two-dimension fountain device is good in sealing property under high-pressure water flow, can be used for enabling the shower nozzle to continuously and freely rotate for 360 degrees and can be widely applied to various fountain facilities.

Description

technical field [0001] The invention relates to a fountain device, in particular to a numerically controlled two-dimensional fountain device. Background technique [0002] At present, with the development of modern society and economy, people's requirements for quality of life are constantly improving, and their aesthetic needs are also constantly strengthening. The water column of the music fountain can change into different three-dimensional shapes with the ups and downs of the music rhythm, bringing people the enjoyment of beauty. The rotary transmission mechanism in the music fountain equipment can realize the two-dimensional rotation of the nozzle in the horizontal and vertical directions. For example, the Chinese patent application number is CN2724853Y, and its name is "Numerical Control Waterscape Performance Device with Pre-editing Function", which discloses a fountain device , the device is composed of a host computer equipped with music signal processing control s...

Problems solved by technology

[0003] But above-mentioned fountain device has the following problems: 1, in the two-dimensional fountain device, owing to the cable wire is sent into the upper dimension rotating mechanism from the lower dimension rotating mechanism, and the rotation state of the upper and lower dimension rotating mechanism, the connection of the cable wire often occurs. Problems, including the cable winding on the rotating transmission mechanism, so that the design of the Shangwei rotating mechanism cannot be made into a form of 360° continuous free rotation, which affects the performance of the fountain

2. The connection and sealing performance of the components in the two-dimensional fountain device is one of the important factors affecting the normal operation of the fountain equipment. The existing sealing device is generally designed for the working condition of the water column height of about 10 meters, and the new fountain The height of the water column of the equipment can reach about 50 meters, so the existing sealing device can no longer bear such a large impact of water flow, and water leakage problems often occur at the dynamic and static junction in the nozzle and the pressure end of the high-lift water head, resulting in the fountain device.
