Vertical impact type double-nozzle overall assembly machine

Abstract

The invention discloses a vertical impact type double-nozzle overall assembly machine and relates to the technical field of water conservation power generation. The vertical impact type double-nozzleoverall assembly machine comprises a tail water pipe, a power generator, a set of water inlet pipes and a pressure pipe. The pressure pipe is composed of a first pipeline and a second pipeline, and afiltering assembly is arranged between the first pipeline and the second pipeline and communicates with the first pipeline and the second pipeline. The filtering assembly comprises a positioning pipe,a filtering pipe and a telescopic pipe. One end face of the positioning pipe is fixedly connected with one end face of the first pipeline through a flange plate and a bolt, the positioning pipe is located in the first pipeline, and an outer threaded sleeve is fixed to one surface of the flange plate of the positioning pipe. The outer diameter of the filtering pipe is the same with the inner diameter of the positioning pipe, and a positioning ring is fixed to one end of the filtering pipe. By means of the vertical impact type double-nozzle overall assembly machine, the pressure pipe is dividedinto the first pipeline and the second pipeline and the filtering assembly is installed between the first pipeline and the second pipeline, so that the problem that an existing double-nozzle overallassembly machine is not provided with a filtering assembly, consequently water inlet pipes are blocked and an impeller is impacted by impurities and is likely to be damaged is solved.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation, in particular to a vertical impact double-nozzle assembly machine. Background technique [0002] When the existing complete machine is in use, the high water level water flow is discharged into the draft pipe through the pressure pipe, the water inlet pipe and the nozzle, and the impact force of the water flow drives the impeller to rotate, thereby driving the shaft on the generator to rotate, thereby realizing power generation and discharge The water flow is discharged through the bottom end of the draft tube. [0003] For the use of the complete machine, it is mostly used in rivers and lakes. However, there will be debris in the water. When large or more debris enters, the baffle plate and nozzle of the deflector on the inlet pipe may There will be blockage, which will affect the power generation efficiency of the whole machine. At the same time, if there are hard debris...
