Noise reduction floor of vertical hydro-generator

Abstract

The invention discloses a noise reduction floor of a vertical hydro-generator. The noise reduction floor of the vertical hydro-generatorcomprises a floor, a third side plate, and a bottom plate,the front end of the floor is fixedly welded to a first side plate, the rear end of the floor is fixedly welded to a second side plate, the third side plate is fixedly welded to the side end of the floor, the bottom plate is fixedly welded to the tail ends of the first side plate, the second side plate, and the third side plate respectively, and a filling cavity is formed between the bottom plate and the floor. According to thenoise reduction floor of the vertical hydro-generator, the third side plate, the first side plate, and the second side plate are all made of foamed fiber aluminum plate materials,since the side platesare thin aluminum plates, easy to bend, can be easily bent into arc shapes, and capable of enclosing areas as large as possible, the first side plate and the second side plateare arranged to realize good sealing effects on the head and tail ends of the floor and the bottom plate so that the noise can be transmitted as less as possible from the side plates,so that the noise can be better transmitted from the middle, and thusthe better noise reduction function is achieved.

Description

technical field [0001] The invention relates to the related technical fields of advanced manufacturing and automation, electric power system and equipment, power generation and energy storage technology, and specifically relates to a noise-reducing floor for a vertical hydroelectric generator. Background technique [0002] During the operation of the power station, the speed of the generator can reach 750r / min. During the high-speed rotation of the rotor, mechanical noise will be generated. The principle of power generation is to generate current by cutting the magnetic induction line, so electromagnetic noise, noise Too much noise will seriously affect the health of the staff, so any unit should reduce the noise as much as possible in order to create a good working environment. [0003] However, the currently used generators will produce noise pollution during the operation of the power station, and the generation of noise is difficult to control, and it is easy to affect t...
