Automatic cleaning device for hydroelectric turbine unit wear-resistant casting and operation method thereof

Abstract

The invention discloses an automatic cleaning device for a hydroelectric turbine unit wear-resistant casting and an operation method thereof, and particularly relates to the field of hydroelectric generation. The automatic cleaning device comprises an equipment stand column and a controller, wherein a first shaft steering engine is fixedly arranged on the top surface of the equipment stand column, a multi-shaft operation arm is fixedly arranged on an output shaft of the first shaft steering engine, a second shaft steering engine is fixedly arranged at one end of the multi-shaft operation arm, an output shaft of the second shaft steering engine is fixedly connected with a rotating rack, a motion deviation rack is arranged in the rotating rack in a sliding mode, and a spray washing machine head is fixedly arranged at the bottom end of the motion deviation rack. According to the scheme, the cleaning device adopts a fan-shaped spray head structure, a high-pressure water curtain is sprayed out so as to flush a casting sand box in a large area, the opening and closing state of a water flow through hole is changed through the driving motion of a driving box and a motion sealing plate so as to change the size of the water curtain or a single-spray-hole structure is directly adopted to flush all surfaces or cavities in the sand box, and the practicability of the cleaning structure is improved.

Description

technical field [0001] The invention relates to the technical field of hydroelectric power generation, and more specifically, the invention is an automatic cleaning device for wear-resistant castings of a hydroelectric turbine unit and an operating method thereof. Background technique [0002] The principle of the hydroelectric turbine generator is: the water flow impacts the turbine assembly to make it rotate, and drives the rotor of the generator to rotate through the main shaft, and direct current is passed into the rotor coil of the generator, and the rotor coil will generate a rotating magnetic field, and the magnetic field lines are in the process of rotation According to the principle of electromagnetic induction, a voltage will be generated in the stator coil, and after the stator coil is connected to the load, a current will be generated in the stator coil. Most of the turbine water flow baffles of the existing hydroelectric turbine generators are limited outside th...

Problems solved by technology

[0004] The existing cleaning method is simple and the cleaning effect is not good. The spraying method of using the high-pressure water gun is time-consuming and laborious. The impact and turbulent flow of the water can easily lead to secondary pollution in the cleaned area, the cleaning effect is poor, and the efficiency of manual cleaning is low. In addition, in the actual operation process, a single water column flushing needs to be sprayed from point to surface, and the surface The adaptability to the complex cavity surfaces inside the sand box is low, and there are easy dead angles and certain defects
