Description

Technical Field

When the placement plate 20 moves to a suitable position, the centrifugal pump 15 in the power mechanism collects water from the performance pool 1, and transmits it to the connecting straight pipe 9 through the output pipeline 16. After being transferred by the folding pipeline mechanism, it is transmitted to the fountain pipeline 22 and finally sprayed out through the nozzle 23, so as to perform a performance. In this process, sealing rings are provided at the connection between the output pipeline 16 and the input pipeline 17 and the performance pool 1, which improves the sealing between the pipeline and the performance pool 1.
