Abstract

The utility model discloses a carbon powder collection device of a cross flow type hydro-generator, comprising a generator body. A rotary shaft of the generator body is horizontally arranged, and a plurality of carbon brushes are uniformly arranged at the outer side of a collecting ring, are contacted with the collecting ring and slide relative to the collecting ring. The carbon powder collection device is characterized in that a dust hood is arranged between the carbon brushes and the collecting ring and enables a cavity among the carbon brushes and the collecting ring to be closed so as to form a closed cavity; and a dust suction hole is arranged on the dust hood, and a dust removal treatment device is communicated with the dust suction hole through a pipeline. In the carbon powder collection device, the closed cavity is formed between the carbon brushes and the collecting ring, seals carbon dust generated by abrasion of the carbon brushes and prevents the carbon dust from polluting the generator and the surrounding space thereof as well as polluting a stator winding and an exciting winding by entering the internal of the generator and the like so as to collect and treat the carbon dust and lower the concentration of the carbon dust in air; and a pumping action of a dust remover carries off loss generated by friction and heating of parts including the carbon brushes and the collecting ring, thereby efficiently lowering the temperature on the surface of a sliding ring.

Description

Fluid-driven hydraulic generator carbon dust gathering-device

Technical field

The utility model relates to a kind of attached environment-friendly processing unit of hydraulic generator, especially fluid-driven hydraulic generator when operation carbon brush gathering-device of the carbon dust that produces that is worn.

Background technology

Hydraulic generator in the present technology, in unit running process, because slip ring (collector ring) is in high speed rotary motion all the time, and carbon brush configuration belongs to stationary parts, contact between the carbon brush in the collector ring of high speed rotary motion and the carbon brush configuration, certainly lead to friction between the two, this kind friction must cause the negative consequence of following three aspects: 1, carbon brush serious wear, and useful life is not long; Will change after the carbon brush wearing and tearing surpass the technology tolerance band, change, shorten the time of generating work and mostly need in the prior art to shut down; When 2, carbon brush weares and teares, form a large amount of carbon dusts tiny, the dust shape; It is indoor that this kind carbon dust spreads in the carbon brush of generator, and rotation under air-flow drives; This dust as do not collected, dust removal process, stator winding and excitation winding etc. further be polluted in the inevitable inside that rotates into generator along with unit, influences the safe operation of unit, can cause coil short etc. in the time of seriously, have serious potential safety hazard; For avoiding the generation of dust, manufactory has adopted several different methods when design, and as electric close, the carbon brush of choosing function admirable of reasonable control carbon brush, slip ring fluting etc., but effect is all undesirable; 3, the collector ring surface temperature is raise, influence operational effect; To this temperature rising phenomenon, lowered the temperature if increase cooling system, must make the gen-set complex structure; Even but increasing cooling system, its effect that cools is undesirable equally.The applicant is in order to address the above problem, on the hydraulic turbine that turbine shaft is vertically arranged, designed the carbon brush integrating device and applied for that August 4 in 2005 name is called " generator carbon brush integrating device ", the patent No. is the utility model patent of ZL200520009727.2; But this kind structure mainly is applicable to the hydraulic turbine that rotating shaft is vertically arranged, and the fluid-driven hydraulic generator that countershaft is horizontal does not still solve some technical problem, does not have the carbon dust gathering-device at the fluid-driven hydraulic generator in the prior art.

Summary of the invention

The utility model is at the carbon dust gathering-device that does not have in the prior art at the fluid-driven hydraulic generator, in the time of can not wearing and tearing to fluid-driven hydraulic generator carbon brush, forming a large amount of carbon dusts, to spread in the carbon brush of generator indoor, along with the internal contamination stator winding that rotates into generator of unit and excitation winding etc., cause coil short, influence the deficiencies such as safe operation of unit, a kind of carbon dust gathering-device that is applicable to the fluid-driven hydraulic generator is provided.

The technical solution of the utility model: fluid-driven hydraulic generator carbon dust gathering-device, comprise generator body, the rotating shaft of generator body is horizontally disposed, and several carbon brush are evenly arranged in the outside of collector ring, contact between carbon brush and the collector ring, each other slide relative; It is characterized in that: between carbon brush and collector ring dust shield is set, dust shield is closed the cavity between carbon brush and the collector ring, forms closed cavity; Suction port is set on dust shield, and dedusting treater is communicated with suction port through pipeline.

Described dust shield along continuous straight runs is arranged, with shaft parallel.

Fluid-driven hydraulic generator carbon dust gathering-device of the present utility model has following characteristics:

1, between carbon brush and collector ring, dust shield is set, make carbon brush and collector ring form closed cavity, the carbon dust that the wearing and tearing of sealing carbon brush produce, avoid carbon dust to pollute generator and space on every side thereof, prevent that carbon dust is along with the internal contamination stator winding that rotates into generator of unit and excitation winding etc.

2, simultaneously, utilize the suction suction function dust suction of dust cleaning apparatus, collection and treatment carbon dust, the concentration of carbon dust in the reduction air.

3, the swabbing action of dust cleaning apparatus, the sealing and circulating loop of formation cooling air is taken away parts such as carbon brush and collector ring because of the loss of friction and heating generation, take away hot-air in dust suction, thereby effectively reduce the slip ring surface temperature.

Embodiment

In Fig. 1,2, fluid-driven hydraulic generator carbon dust gathering-device of the present utility model comprises generator body 1, and the rotating shaft 2 of generator body 1 is horizontally disposed, and carbon brush 3 is in the outside, and several carbon brush 3 are evenly arranged in the outside of collector ring 4; Contact between carbon brush 3 and the collector ring 4, during work successively between slide relative, normally collector ring 4 high speed rotating and carbon brush 3 maintains static.Above as prior art, be not further described at this.

Improvement of the present utility model, be between carbon brush 3 and collector ring 4, dust shield 5 to be set, dust shield 5 is closed the cavity between carbon brush 3 and the collector ring 4, forms closed cavity 6, closed cavity 6 with carbon brush 3 because of and collector ring 4 between the carbon dust of wearing and tearing generation seal.Suction port 7 is set on dust shield 5, and dedusting treater 8 is communicated with suction port 7 through pipeline 9, produces swabbing action during dedusting treater 8 work, and the carbon dust in the closed cavity 6 in pipeline 9 is drawn into dedusting treater 8, is collected and dust removal process.

As further improvement of the utility model, described dust shield 5 along continuous straight runs layout, roughly parallel with rotating shaft 2, more can save the locus, the convenient setting.
