Description
Technical field
The utility model relate to a kind of can on-line monitoring vacuum device inside cavity vacuum tightness change intelligent vacuum device on-Line Monitor Device, can be used for the on-line monitoring of all vacuum devices.
Background technology
Vacuum device is using vacuum as actuating medium, therefore low internal gas pressure (condition of high vacuum degree) is all vacuum devices is able to the basis of normal work.When vacuum device gas leakage or material outgassing cause the gas pressure intensity of its inside higher than SC service ceiling, vacuum device will lose efficacy, and cannot normally work, and especially in power industry, severe patient can bring harm to electrical network, causes fortune to lose, even casualties.
At present, on market during existing vacuum device on-line operation, if need the vacuum tightness change detecting this vacuum device interiors of products, carry out off line detection after usually can only shutting down, therefore substantially increase operation and maintenance cost.
For meeting the requirement that user detects in real time to vacuum device, carry out studying for many years to this both at home and abroad, for example adopt ionization method, coupling capacitance method, the electric discharge method of voice production etc., but these methods are still in research or Preliminary Applications stage at present, and be collection electric signal for analyzing judgement, only can be used for the vacuum device of special construction, the problem that simultaneously these measuring methods cannot be avoided is: the electromagnetic field how avoiding product self to produce to the interference of measuring accuracy, to reach pin-point accuracy.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of intelligent vacuum device on-Line Monitor Device, can monitor in real time vacuum device interiors of products vacuum tightness.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of intelligent vacuum device on-Line Monitor Device, comprise and being located on vacuum seal cavity and one end connecting pipe of being communicated with inner with this vacuum seal cavity, and the corrugated tube to be communicated with this connecting pipe other end, this corrugated tube fixes a Photoinduction device away from the other end of this connecting pipe, separately be provided with light emitting devices and optical pickup apparatus, this light emitting devices utilizing emitted light signal is monitored the position of this Photoinduction device continuously and is transferred to optical pickup apparatus, this optical pickup apparatus by receive light signal by optical cable transmission to central processing unit.
As further improvement of the utility model, described Photoinduction device is grating.
As further improvement of the utility model, described light emitting devices and optical pickup apparatus are arranged at the relative both sides of this grating respectively.
As further improvement of the utility model, described connecting pipe is metal tube.
As further improvement of the utility model, be also provided with indicator, the vacuum tightness in described vacuum seal cavity is reduced to and uses lower prescribing a time limit, and this indicator sends alerting signal.
The beneficial effects of the utility model are: this intelligent vacuum device on-Line Monitor Device is changed by the vacuum tightness of light signal continuous surveillance vacuum device, when detecting that in device, vacuum tightness is prescribed a time limit under being down to use, indicator can give a warning, namely give a warning in time before product failure, remind staff to take measures, avoid accident to occur.Not only reduce or remit the off-line test to vacuum device, reduce operation and maintenance cost; And add the reliability of product, decrease the risk that employee, client and assets are injured; And can remote monitoring be realized, the development of "smart" products is played a role in promoting.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view.
By reference to the accompanying drawings, make the following instructions:
1---vacuum cavity 2---connecting pipe
3---corrugated tube 4---Photoinduction device
5---light emitting devices 6---optical pickup apparatus
Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
A kind of intelligent vacuum device on-Line Monitor Device, as shown in Figure 1, comprise and being located on vacuum seal cavity 1 and one end connecting pipe 2 of being communicated with inner with this vacuum seal cavity, and the corrugated tube 3 to be communicated with this connecting pipe other end, this corrugated tube is away from the other end of this connecting pipe being fixed a Photoinduction device 4, separately be provided with light emitting devices 5 and optical pickup apparatus 6, this light emitting devices utilizing emitted light signal is monitored the position of this Photoinduction device continuously and is transferred to optical pickup apparatus, this optical pickup apparatus by receive light signal by optical cable transmission to central processing unit.Wherein, connecting pipe preferably uses metal tube, and Photoinduction device preferably uses grating.
This intelligent vacuum device on-Line Monitor Device operationally, if vacuum cavity gas leakage causes its internal vacuum to decline, corrugated tube is due to by the inner conducting of connecting pipe and vacuum cavity, namely the two pressure is consistent, therefore the gas leakage with vacuum cavity produces and stretches change by corrugated tube, and Photoinduction device and grating are fixed on this corrugated tube, therefore grating will be subjected to displacement along with the stretching, extension of corrugated tube, the light signal of optical pickup apparatus change detected, and by optical cable transmission to central processing unit, if vacuum tightness is reduced to use lower limit, grating will the path of blocking light signal, separately can be provided with indicator to report to the police, such operating personnel can understand the leakage problem of vacuum cavity in time, and relevant electric operation can be stopped by interlock mechanism.
Therefore, this on-Line Monitor Device so that understand vacuum cavity air pressure inside situation in time, namely can give a warning before product failure, reminds staff to take measures, avoid accident to occur in time.Not only reduce or remit the off-line test to vacuum device, reduce operation and maintenance cost; And add the reliability of product, decrease the risk that employee, client and assets are injured; And can remote monitoring be realized, the development of "smart" products is played a role in promoting.
In addition, for the seal chamber that inside cavity inflation (i.e. normal pressure) has impermeability to require, real-time detection can be realized by the frame mode of this on-Line Monitor Device and by the pressure change of light signal continuous surveillance seal chamber device inside equally.
