Description
Technical field
The invention belongs to hydraulic technique and new energy fields, and in particular to a kind of wind power generation gear case oil leakage prison
Examining system.
Background technique
Wind-power electricity generation enters domestic many years, but along with prolonged operation, the aging of component and components is more next
More serious, later period failure is more and more, and oil leakage phenomenon also becomes one of fan operation failure, at present in addition to manpower early stage is checked,
Substantially without measure can early detection often have resulted in serious consequence and when discovered.
It is several that oil leakage phenomenon is broadly divided into leakage, water clock, linear leakage and spray leakage etc..Leakage and water clock can be in morning
Found in time in the manpower investigation of phase, caused by lose be not very big, but linear leakage and spray leakage are due to liquid in the short time
Body largely flows out, especially spray leakage, if cannot shut down in time, caused by loss and consequence be also most serious.
A kind of wind turbine generator gearbox oil liquid on-line monitoring dress is disclosed in 103033450 A of China Patent Publication No. CN
It sets and monitoring method, which includes power protection plate, power template, microprocessor, wireless module, front end sensors, wherein
Power module includes 24V power module and 5V power module, front end sensors include Oil Quality sensor, moisture transducer and
Metal particle sensor.Foregoing invention accesses front end sensors in gearbox oil-channel, realizes to Oil Quality, moisture and metal
The acquisition of wear particle data, and microprocessor is transmitted in a manner of bus, microprocessor will collect data and pass through wirelessly
Module carries out teletransmission in a manner of wireless telecommunications, and remote terminal receives the data that scene sends over, realize to moisture in oil liquid,
The on-line monitoring of Oil Quality and metallic particles data, but without the function of monitoring gear box lubricating oil leakage, it can not be to profit
Lubricating oil leaks on a small quantity, spray leakage caused by the water clock and pipelines from bursting of sealing position makes alarm and sends host control system to
System prevents from losing further expansion caused by leakage so that gear-box be made to shut down.
Summary of the invention
The purpose of the present invention is to above-mentioned the deficiencies in the prior art to provide one in hydraulic technique and new energy field
Kind wind power generation gear case oil leakage monitors system, and this system installation is simple, easy to use, while can find tooth in time
Roller box is leaked and is stopped loss in time, by gear-box because caused by leakage the damage control to minimum.
The technical solution adopted by the invention is as follows: a kind of wind power generation gear case oil leakage monitors system, it includes
There are gear-box and master control system, it is characterised in that it further includes having liquid level sensor, leak sensor, sonic sensor and data
Processor, the gear-box are connected by route with liquid level sensor, the liquid level sensor, leak sensor and sound wave sensing
Device is connected by route with data processor, and the data processor is mounted in master control system.
On the drive means, wherein the quantity of leak sensor can be one or more for the leak sensor installation of this system
It is a.
The beneficial effects of the present invention are as follows: this system installation is simple, and it is easy to use, lubricating oil can be monitored within 24 hours and seeped on a small quantity
It leaks, spray leakage problem caused by the water clock and pipelines from bursting of sealing position, and issues alarm signal to master control system, make master control
System hard stop prevents from losing further expansion caused by leakage, ensure that the reliability service of wind power generation gear case, save
Cost.

Specific embodiment
The present invention is further described with reference to the accompanying drawing:
As shown in Figure 1, the present invention it include gear-box 6 and master control system 7, it is characterised in that it further includes having liquid level sensor
1, leak sensor 2, sonic sensor 3 and data processor 5, the gear-box 6 are connected by route with liquid level sensor 1,
The liquid level sensor 1, leak sensor 2 and sonic sensor 3 are connected by route with data processor 5, be used for this three
The output signal of kind of sensor is analyzed and judges whether to need to issue alarm signal, and wherein the quantity of leak sensor can be with
It is one or more, which is mounted in driving device 4, for single location monitoring or multiple position monitorings.Institute
It states data processor 5 to be mounted in master control system 7, for sending the alarm signal for needing to issue to master control system 7, then lead
The start and stop of the control gear-box 6 of control system 7.
Monitoring method of the invention is as follows:
The liquid level sensor 1 due to use analog output, so as to the oil level to lubricating oil in gear-box 6 change into
The continuous uninterrupted monitoring of row, after gear-box 6 operates normally, the oil level of lubricating oil is substantially constant, if sometime
Section, the oil level in gear-box 6 is lower suddenly, and continues to decline, at this point, the also synchronous variation of the output signal of liquid level sensor 1,
Then data processor 5 changes according to the output signal of liquid level sensor 1, judges oil level exception, issues alarm signal immediately
To master control system 7, then master control system 7 issues halt instruction, and wind power generation gear case is out of service.
The leak sensor 2 is mounted in driving device 4, and the driving device 4 is driven by the stroke and speed of setting
The leak sensor 2 carries out intermittent scanning to 6 surface of gear-box and 6 following area of gear-box, if 6 lubricating oil of gear-box is at certain
A position issue leakage (leakage, water clock, it is linear leak or spray leakage), when oil liquid is fallen on 6 surface of gear-box or ground, quilt
The scanning of leak sensor 2 causes the output signal of leak sensor 2 to change to exception, this variation is by data processor 5
Receive and process, master control system 7 issued instructions to after judgement, then 7 pairs of instructions received of master control system can carry out alarm or
Issue halt instruction.
The sonic sensor 3 is mounted in cabin and close to gear-box 6, when gear-box 6 is under normal operating condition
When, the acoustic signals of each frequency range are collected by sonic sensor 3 and are stored into data processor 5, when pipeline bursts, are moistened
Spray leakage occurs for lubricating oil, and the sound that spray leakage generates is collected by sonic sensor 3, simultaneous transmission to data processing
In device 5, since the signal that this signal and data processing device 5 originally stored is inconsistent, so that data processor 5 issues abnormal signal
To master control system 7, then master control system 7 issues halt instruction immediately, and then wind power generation gear case is out of service, keeps leakage vertical
Interrupt.
Other undeclared parts of the present invention are same as the prior art.
