Description
Technical field
The utility model relates to vibration online monitoring technical field, is specifically related to a kind of vibration on-line monitoring device for hydraulic turbine drive apparatus.
Background technology
The hydraulic turbine is the power machine of rotating mechanical energy the energy conversion of current, and it belongs to the turbomachinery in fluid machinery.Before and after B.C. 100 years, just there are the blank of the hydraulic turbine---water wheels, for irrigating by lifting water to a higher level with a water pump, etc. and drive grain processing apparatus in China.The modern hydraulic turbine then great majority is arranged in power station, is used for driving electrical power generators.In power station, the water in upper pond guides the hydraulic turbine into through aqueduct, and promote rotary wheel of water turbine and rotate, drive electrical generators generates electricity.The water finishing merit then by tail water pipeline discharged to downstream.Head is higher, flow is larger, and the output power of the hydraulic turbine is also larger.Along with the continuous application of the hydraulic turbine, it vibrates the series of problems brought and more and more comes into one's own, and how to address these problems and become current main direction of studying, meanwhile, the monitoring of vibration becomes householder method most popular at present.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, a kind of vibration on-line monitoring device for hydraulic turbine drive apparatus reasonable in design, easy to use, it adopts and arrange Pointing stick on transmission shaft connecting bushing, and coordinates with direction board, utilize metal tip and resistive band, coordinate power supply and signal picker to form acquisition circuit, and it have easy to use, simple to operate, practicality is good, detectability high.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of vibration on-line monitoring device for hydraulic turbine drive apparatus described in the utility model, comprise drive apparatus, transmission shaft and axle sleeve, described transmission shaft is connected with connection for transmission equipment, other end socket axle sleeve, described axle sleeve is provided with Pointing stick, described Pointing stick is positioned at boss surfaces, flush with transmission shaft, described Pointing stick top is provided with metal tip, and be connected with direction board, described direction board is provided with resistive band, flushes mutually with metal tip, described metal tip and resistive band adopt electric wire to be connected with signal picker, power supply.
Described Pointing stick is needle-like, and diameter is not more than 1mm, and described metal tip length is not more than 5mm.
Described resistive band adopts bonding mode to be fixed on direction board.
After adopting said structure, the utility model beneficial effect is: its employing of the utility model arranges Pointing stick on transmission shaft connecting bushing, and coordinates with direction board, utilizes metal tip and resistive band, coordinates power supply and signal picker to form acquisition circuit; Adopt the Pointing stick flushed with transmission shaft, in needle-like, can by trickle conduct vibrations to metal tip, the vibration that formation amplitude is larger, play the effect improving detectability, utilizing simultaneously and vibrate the resistance value that the amplitude brought changes place in circuit, form the change of electric current, judging vibrational state by gathering curent change; Adopt the mode fixed resistance band of bonding not only to facilitate the replacing of resistive band, and contribute to its solidifying on direction board, difficult drop-off; And it has easy to use, simple to operate, practicality is good, detectability high.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of vibration on-line monitoring device for hydraulic turbine drive apparatus described in the utility model, comprise drive apparatus 1, transmission shaft 2 and axle sleeve 3, described transmission shaft 2 is connected with connection for transmission equipment 1, other end socket axle sleeve 3, described axle sleeve 3 is provided with Pointing stick 4, described Pointing stick 4 is positioned at axle sleeve 3 surface, flush with transmission shaft 2, described Pointing stick 4 top is provided with metal tip 9, and be connected with direction board 5, described direction board 5 is provided with resistive band 8, flush mutually with metal tip 9, described metal tip 9 adopts electric wire and signal picker 6 with resistive band 8, power supply 7 is connected.
Described Pointing stick 4 is in needle-like, and diameter is not more than 1mm, and described metal tip length is not more than 5mm.
Described resistive band 8 adopts bonding mode to be fixed on direction board 5.
Its employing of the utility model arranges Pointing stick on transmission shaft connecting bushing, and coordinates with direction board, utilizes metal tip and resistive band, coordinates power supply and signal picker to form acquisition circuit; Adopt the Pointing stick flushed with transmission shaft, in needle-like, can by trickle conduct vibrations to metal tip, the vibration that formation amplitude is larger, play the effect improving detectability, utilizing simultaneously and vibrate the resistance value that the amplitude brought changes place in circuit, form the change of electric current, judging vibrational state by gathering curent change; Adopt the mode fixed resistance band of bonding not only to facilitate the replacing of resistive band, and contribute to its solidifying on direction board, difficult drop-off; And it has easy to use, simple to operate, practicality is good, detectability high.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
