Description
Technical field
The utility model belongs to on-line condition monitoring technical field, is related to a kind of boiler expansion displacement sensing apparatus.
Background technology
Modern each structure member of boiler is connected with each other one intensity entirety of composition in different ways.Each component of boiler is because of temperature
Difference will produce the active force of expansion.When boiler works, Expansion Center will produce displacement according to scheduled expansion direction.Positive reason
Under condition, the displacement of Expansion Center can be in certain range.It is actual swollen but when swelling blockage or guider fail
Swollen coefficient can and design value generate deviation, the stress situation of related force-summing element can also change, and component's life is caused to decline,
The problem of even bringing short term failure.These all bring titanic peril hidden danger to the operation and maintenance of boiler.
Invention content
The purpose of this utility model be propose it is a kind of can be to sensing device that boiler expansion displacement is detected.
The technical solution of the utility model is, boiler expansion displacement sensing apparatus include expansion displacement sensing element and
Node acquires pick-up device.Expansion displacement sensing element is made of the three-dimensional plane of reference and laser range finder, three-dimensional plane of reference welding
Mounted on the outer surface of boiler body, each axial plane of reference corresponds to a laser range finder, and three laser range finders are logical
It crosses on the girder steel that holder is fixed on outside boiler body.When boiler expands deformation, the plane of reference is generated with boiler body
The variation of displacement, and it is then opposing stationary in position to be fixed on the laser range finder outside boiler body on girder steel holder, so often
A shaft orientation laser rangefinder can be considered as the variable quantity of boiler expansion displacement to the distance change amount of the plane of reference.
Three laser range finders are connected with node acquisition pick-up device.The Switching Power Supply that node acquires pick-up device will exchange
220V is converted to direct current+24V and is used for signal acquisition transmitting module and laser range finder, while being adopted by node acquisition pick-up device
Collect the displacement data of laser range finder output.
The present invention has the advantage that and advantageous effect
The displacement of boiler expansion is converted to a kind of detectable distance by the utility model by the change of measurement method
Amount.This distance measurements are obtained by laser range finder.This is also the most crucial part of boiler expansion displacement sensing apparatus.Node is adopted
Collection pick-up device is responsible for acquiring and transmitting displacement data.Boiler expansion displacement sensing apparatus is installed on around boiler body, to closing
The three-D displacement variable quantity of key position is acquired in real time, from realizing quick, simple, light and handy, inexpensive monitoring mode.
Description of the drawings
Fig. 1 is the block diagram of system of the utility model.
Fig. 2 is the utility model expansion displacement sensing element block diagram.
Specific implementation mode
It elaborates to the embodiment of the utility model in conjunction with attached drawing.As shown in Figure 1, 2, the three-dimensional plane of reference 1 and three
A laser range finder 2 has collectively constituted boiler expansion displacement sensing component.The three-dimensional plane of reference is welded in boiler wall outer surface, laser
Rangefinder according to around, vertical direction is mounted on the girder steel holder outside furnace body.Node acquires pick-up device
Alternating current 220V is become direct current+24V power supplys and powered to signal acquisition transmitting module 3 and laser range finder by AC/DC Switching Power Supplies 4.
Signal acquisition transmitting module acquires the displacement data of laser ranging output by communication cable.
Above be specific embodiment of the present utility model, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made by within principle should be included in the scope of protection of the utility model.
