Description
Technical field
The utility model relates to technical field of hydraulic generators, specially a kind of vertical hydrogenerator of low noise.
Background technique
Hydrogenerator refers to the generator for converting water energy to using the hydraulic turbine as prime mover electric energy, and water flow passes through the hydraulic turbine
When, water energy is converted into mechanical energy, the shaft of the hydraulic turbine drives the rotor of generator again, converts mechanical energy into electric energy and defeated
It out, is the main dynamics equipment of power station production electric energy, hydrogenerator can be divided into vertical and horizontal two class by axial location,
Middle vertical hydrogenerator includes the hydraulic turbine and generator, and existing generator is generally held by the thrust bearing of upper end setting
The gravity of generator upper rotor part is carried on a shoulder pole, and the hydrodynamic bearing seat being in addition specially arranged by top pushes away to undertake the axial direction of the hydraulic turbine
Phenomena such as power, therefore cause generating set arrangement space big, operational efficiency is low, and installation maintenance is at high cost, and it is existing vertical
There is a problem of that noise is big in hydrogenerator operational process, there is test to show that part vertical hydrogenerator is transported at full capacity
When row, the level of noise measured at 1 meter of shell of disembarking is up to 110 decibels, thus it is necessary to make improvements.
Utility model content
For the technical issues of the utility model is solved in providing a kind of low noise vertical hydrogenerator, the low noise is vertical
Operating noise is effectively reduced in hydraulic generator function.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of vertical hydrogenerator of low noise, including the hydraulic turbine and power generator, the hydraulic turbine are set to power generator
Bottom, power generator include casing, and cabinet top and bottom pass through upper spider respectively and lower cover is sealed, the casing side
Denoising structure is provided on wall, denoising structure is the sound absorbing layer for being set to casing inner wall；
The sound absorbing layer is the metal mesh panel for being set to casing inner wall, and metal mesh panel is in honeycomb structure；
Interval is embedded with multiple pieces of glass blanket, multiple pieces of glass blanket matrix in metal mesh panel in the metal mesh panel
Arrangement.
The thrust bearing for undertaking rotor gravity is provided on the upper spider and for undertaking turbine shaft to pushing away
The top guide bearing of power, top guide bearing are sheathed on outside thrust bearing and are fixedly connected with upper spider.
The top guide bearing is transverse bearing.
Circumferential washer is provided between the top guide bearing and thrust bearing.
The thickness of the metal mesh panel is set as 1~1.5cm.
The utility model has the advantages that a kind of vertical hydrogenerator of low noise described in the utility model, dedicated without being additionally arranged
Hydrodynamic bearing seat, thus structure is more compact, installs more convenient, reduces the mechanical loss of unit, while greatly drop
Low operation noise, effective noise reduction function pollution, has preferable actual application prospect.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to a kind of preferred embodiment of vertical hydrogenerator of Fig. 1, vertical hydrogenerator includes in the present embodiment
The hydraulic turbine and power generator, the hydraulic turbine are set to power generator bottom, and power generator includes casing 1 and vertical shaft 3, casing
1 bottom is supported by stabilizer blade 2, and 1 top and bottom of casing passes through upper spider 4 respectively and lower cover 5 is sealed, upper spider
4 are fixed at the top of casing 1 by bolt assembly, and casing 1 is internally provided with stator 9 and rotor 8, and vertical shaft 3 is successively worn
The upper spider 4 and lower cover 5 crossed on casing 1 and connect with the hydraulic turbine, stator 9 is fixedly connected with 1 inner wall of casing, rotor 8 and perpendicular
It being fixedly connected to shaft 3, vertical 3 top of shaft is arranged with thrust bearing 7, top guide bearing 6 is fixed with outside thrust bearing 7, on
Guide bearing 6 is transverse bearing, circumferential washer is provided between top guide bearing 6 and thrust bearing 7 to reduce friction loss, upper leading axle
6 are held to be fixedly connected with upper spider 4 by bolt assembly.In the present embodiment, in order to reduce noise pollution, set on 1 side wall of casing
It is equipped with denoising structure, denoising structure is the sound absorbing layer for being set to casing inner wall, specifically, as shown in Fig. 2, sound absorbing layer is that bonding is solid
Due to the metal mesh panel 10 of casing inner wall, metal mesh panel 10 is in honeycomb structure, with a thickness of 1cm or so, and metal mesh
Interval is embedded with multiple pieces of glass blanket 11 in panel 10, and the matrix in metal mesh panel 10 of multiple pieces of glass blanket 11 is arranged, power generation
In machine operational process, the noise of generation shuttles in the taffoni of metal mesh panel 10 and is weakened, and complementary glass
Blanket has good absorption effect to noise, therefore 1 inner wall of casing can absorb and weaken most of noise, to be transferred to outside
Noise substantially reduce, thus good noise reduction effect is played, simultaneously because metal mesh panel 10 will can produce rapidly inside casing 1
Raw heat conduct in time on 1 outer wall of casing to make heat be distributed faster, to preventing hair caused by heat accumulation
