Description
Technical field
The utility model belongs to Industrial Boiler Technology field, is used to detect large fan rotating more particularly, to a kind of
Measurement apparatus.
Background technology
In thermal power plant's large fan start-up course, the situation of blower fan reversion is frequently encountered, the startup to blower fan has an impact,
If without finding in time, motor burning is easily caused, but because blower motor rotating speed is higher, only by visually observe can not be timely
It was found that motor reversal, it is therefore desirable to research and develop the detection means of accurate judgement blower fan rotating.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind is used to detect large fan rotating
Measurement apparatus.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of measurement apparatus for being used to detect large fan rotating, including three be respectively adhered on fan blade are anti-
Striation, three reflective strips are identical, and the interval angles based on counterclockwise are respectively 45 °, 90 ° and 135 ° between any two,
The opposite that fan blade is pasted with reflecting strips is placed with laser detecting apparatus, and laser detecting apparatus is launched to the reflecting strips on fan blade
Laser beam, and the reflected beams are received, wherein, the laser detecting apparatus includes detector housing, pacifies on the leading flank of housing
Equipped with laser signal transmitting and recipient, blower fan is installed on the upper surface of housing and rotates forward indicator lamp and blower fan reversion instruction
Lamp, signaling switch and power switch are disposed with the bottom of two indicator lamps, are provided with the inside of housing and laser signal
The optical signal received is converted into simulating electric pulse letter by transmitting and the photoelectric conversion module of recipient connection, photoelectric conversion module
Number, the pulse spacing judge module connection of photoelectric conversion module and electric impulse signal, pulse spacing judge module touches with indicator lamp
Hair switch connection, indicator lamp trigger switch rotates forward indicator lamp with blower fan respectively and blower fan reversion indicator lamp is connected, whole laser inspection
Instrument is surveyed by battery-powered.
Moreover, the battery pack is from two No. 1 alkaline batteries of section.
The advantages of the utility model and good effect are：
The utility model pastes reflecting strips by fan radiating blade diverse location, is aligned by Handheld laser detector
Motor radiating blade launches laser signal, by the frequency interval of reflecting piece feedback signal, device accurate judgement fan blade
Direction of rotation, blower fan is avoided to damage.

Embodiment
The utility model embodiment is further described below in conjunction with accompanying drawing, it is emphasized that, implementation below
It is illustrative, rather than limited, it is impossible to be used as in this embodiment to restriction of the present utility model.
A kind of measurement apparatus for being used to detect large fan rotating, as shown in figure 1, including being respectively adhered on fan blade
Three reflecting strips 2 on 1, three reflective strips are identical, and between any two the interval angles based on counterclockwise be respectively 45 °,
90 ° and 135 °, the opposite that reflecting strips are pasted with fan blade is placed with laser detecting apparatus 3, and laser detecting apparatus is to fan blade
On reflecting strips transmitting laser beam, and receive the reflected beams, as shown in Fig. 2 wherein, the laser detecting apparatus includes detector
Housing 4, laser signal transmitting and recipient 5 are installed on the leading flank of housing, blower fan is installed on the upper surface of housing
Indicator lamp 6 and blower fan reversion indicator lamp 7 are rotated forward, signaling switch 8 and power switch 9 are disposed with the bottom of two indicator lamps,
As shown in figure 5, the photoelectric conversion module being connected with laser signal transmitting and recipient, opto-electronic conversion are installed in the inside of housing
The optical signal received is converted into simulating electric impulse signal by module, and the pulse spacing of photoelectric conversion module and electric impulse signal is sentenced
Disconnected module connection, pulse spacing judge module rotate forward electric impulse signal to the blower fan of input, as shown in figure 3, and blower fan reversion electricity
Pulse signal, as shown in figure 4, being differentiated, pulse spacing judge module is connected with indicator lamp trigger switch, is sentenced when the pulse spacing
When disconnected module is judged as that blower fan rotates forward electric impulse signal, indicator lamp trigger switch connects blower fan and rotates forward indicator lamp, works as the pulse spacing
When judge module is judged as blower fan inversion electrical pulse signal, indicator lamp trigger switch connects blower fan reversion indicator lamp, whole laser
Detector is by battery-powered.
In specific implementation of the present utility model, the battery pack is from two No. 1 alkaline batteries of section.
