Abstract

The invention discloses an inflow pipeline, and belongs to the field of marine mechanical equipment. The inflow pipeline comprises a pipe body which is provided with a viewport, and the inflow pipeline further comprises an access panel component comprising a sleeve and an access panel; the access panel component is arranged on the pipe body of the inflow pipeline, and comprises the sleeve and theaccess panel; the sleeve is coaxially arranged in the viewport by insertion, and fixedly connected to the pipe body; the access panel comprises a barrel with one end closed, and the barrel is movablyarranged in the sleeve by insertion, and movably connected to the sleeve; and when the barrel is arranged in the sleeve by insertion, the barrel is hermetically matched with the sleeve. The viewport of the inflow pipeline is fixedly provided with the sleeve, so that the access panel can be installed on the inflow pipeline through the sleeve; and thus the arrangement of a threaded hole on the pipebody of the inflow pipeline is not required.

Description

technical field [0001] The invention relates to the field of marine mechanical equipment, in particular to an inlet pipeline. Background technique [0002] Water jet propulsion is a kind of ship propeller, which drives the ship by the reaction force generated by jet water. The water jet propulsor generally includes an inlet pipe, a water jet propulsion pump connected to the outlet end of the inlet pipe, and a main shaft that drives the water jet propulsion pump to rotate. [0003] The pipe wall of the inlet pipe is usually provided with an observation port, and the observation port is provided with an observation cover. The water jet propeller works by sucking water from the bottom of the ship through the inlet pipe. However, due to the unsatisfactory water quality, weeds, fishing nets, etc. May also be sucked into the water jet and wind up around the main shaft, so the debris wrapped around the main shaft can be removed by opening the viewing cover. [0004] In the proces...
