Pipeline may bear the effect of many kinds of external force, include the weight of itself（Pipe, valve, pipe connector, heat preservation
The weight of layer and tube fluid）, fluid pressure act on the thrust of pipe end, wind and snow load, ground pressure, expanding with heat and contract with cold causes
Thermal stress, oscillating load and earthquake disaster etc..In order to ensure the strength and stiffness of pipeline, it is necessary to set various branch（It hangs）Frame,
Such as movable support, fixing bracket, guiding trestle and spring support.The setting of stent is according to the diameter of pipeline, material, tube wall
The conditional decisions such as thick and load.
In high temperature environments using after a period of time, pipeline is easily deformed pipeline, as partly heaved, seriously affects pipeline
Be continuing with.
And the detections such as crackle are concentrated mainly on to the detection of inner-walls of duct in the prior art, such as Chinese patent CN
A kind of alternating current field measurements for pipeline detection of 105866237A are popped one's head in, including：Cylinder, with hollow channel；
Coil mechanism is located on outside the cylinder, and the coil mechanism is made of multiple coil units, multiple coil unit edges
The circumferencial direction of the cylinder is uniformly arranged, and multiple sensors are both provided on the outer wall of each coil unit.But it is simultaneously
It cannot be used for the detection of internal diameter of the pipeline variation.
Utility model content
The utility model provides a kind of device for internal diameter of the pipeline detection, and effectively internal diameter of the pipeline can be detected.
To realize above-mentioned technical purpose, it is that one kind detects for internal diameter of the pipeline that the utility model, which takes particular technique means,
Device, including laser generator, laser pickoff and block；Laser generator is arranged on one end of pipeline；Laser pickoff
The other end of pipeline is correspondingly arranged at, for receiving the laser beam of vertical cavity surface emitting laser transmitting；It blocks arranged on vertical cavity surface
Between emitting laser and laser pickoff, and it can be rolled under the effect of external force along pipe lengths；Laser generator energy
Transmitting is not less than the laser beam for maximum cross section area of blocking, and laser beam is oriented parallel to pipe lengths, and laser
The extreme lower position of beam is not higher than the center blocked.
As the improved technical solution of the utility model, laser generator is set up in pipeline opening by stent.
As the improved technical solution of the utility model, laser pickoff is set up in pipeline opening by stent.
As the improved technical solution of the utility model, block as wooden ball or Ceramic Balls.
As the improved technical solution of the utility model, displacement sensor is further included, displacement sensor is in blocking
Heart position.
Advantageous effect
The application mainly utilizes the straightline propagation principle of light, the area of the laser beam beam emitted by detecting laser generator
The area of the laser beam received with laser pickoff, can effectively judge to block in the medium-altitude variation of rolling process, pass through gear
It is raised or fluted that the variation of ball height can effectively judge that inner-walls of duct has.
To sum up, the apparatus structure of the application is simple, can be effective for the detection of inner-walls of duct etch state or fouling state.

Specific embodiment
To make the purpose of the embodiment of the present application and technical solution clearer, below in conjunction with the embodiment of the present application to this Shen
Technical solution please is clearly and completely described.Obviously, described embodiment is the part of the embodiment of the application, and
The embodiment being not all of.Based on described embodiments herein, those of ordinary skill in the art are without creative labor
All other embodiments obtained on the premise of dynamic, shall fall in the protection scope of this application.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein（Including technology art
Language and scientific terminology）With the identical meaning of the general understanding with the those of ordinary skill in the application fields.Should also
Understand, those terms such as defined in the general dictionary, which should be understood that, to be had and the meaning in the context of the prior art
The consistent meaning of justice, and unless defined as here, will not be with idealizing or the meaning of overly formal be explained.
In embodiment,
Laser generator 1,
Laser beam 2,
Laser pickoff 3,
Pipeline 4,
Block 5.
As shown in Figure 1, a kind of device for internal diameter of the pipeline detection, including laser generator, laser pickoff and gear
Ball；
Laser generator is arranged on one end of pipeline；Laser pickoff is correspondingly arranged at the other end of pipeline, vertical for receiving
The laser beam of cavity surface emitting lasers transmitting；
It blocks arranged between vertical cavity surface emitting laser and laser pickoff, and can under the effect of external force can be along pipeline
Length direction rolls；
Laser generator can emit the laser beam not less than maximum cross section area of blocking, and laser beam is oriented parallel to pipe
Road length direction, and the extreme lower position of laser beam is not higher than the center blocked.
When specifically used, to block apply an active force, the size of active force can guarantee block can occur it is long along pipeline
Spend the displacement in direction；Laser generator emits laser beam, and fraction of laser light is blocked stop so that laser pickoff connects in laser beam
The laser beam area received is less than the laser beam area of laser generator transmitting.
