Abstract
The invention discloses a kind of guide vane lever that can measure corner, including guide vane lever main body and the installation arm that is connected with its side, the notch through with guide vane lever main body it is provided with on described installation arm, it is provided with to detect the rotary angle transmitter of guide vane lever body rotation angle in this notch, it is provided with top pressure closure on described notch, arranging porose on this top pressure closure, the conduit of built-in electric wire can pass from this hole.Described rotary angle transmitter is touch sensor, on the outer wall of the guide vane lever main body that it is fixed in notch.After using said structure, above-mentioned rotary angle transmitter can accurately detect the rotational angle of guide vane lever main body during use, thus can control to lead leaf divergence easily, and rotary angle transmitter can be sealed in notch by top pressure closure, after preventing outside water from entering, reduce the service life of rotary angle transmitter.
Description
Technical field
The present invention relates to a kind of guide vane lever, a kind of guide vane lever that can measure corner.
Background technology
The rotational angle of guide vane lever controls to lead leaf divergence, and therefore the detection to guide vane lever rotational angle is the most important.
At present, after guide vane lever machines, typically can do the detection of a guide vane lever rotational angle, mainly by with pointer
Connecting rod, the angle that manual observation rotates, detect loaded down with trivial details, reliability is low, and to the angle of rotation of guide vane lever during actually used
Degree cannot detect.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of simple in construction, survey
Amount reliability is high, and can measure the guide vane lever that can measure corner of rotational angle during use.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of guide vane lever that can measure corner, including guide vane lever main body and the installation arm that is connected with its side, described installation
It is provided with the notch through with guide vane lever main body on arm, is provided with in this notch to detect turning of guide vane lever body rotation angle
Angle transducer, described notch is provided with top pressure closure, this top pressure closure is arranged porose, and the conduit of built-in electric wire can be from this hole
In pass.
Described rotary angle transmitter is touch sensor, on the outer wall of the guide vane lever main body that it is fixed in notch.
It is evenly arranged with several installing holes on the circumference of described guide vane lever body top.
O RunddichtringO it is filled with between described conduit and hole.
After the present invention uses said structure, above-mentioned rotary angle transmitter can accurately detect guide vane lever main body during use
Rotational angle, thus can control to lead leaf divergence easily, rotary angle transmitter can be sealed in notch, outside preventing by top pressure closure
After side water enters, reduce the service life of rotary angle transmitter.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of guide vane lever that can measure corner of the present invention.
Wherein have: 1. guide vane lever main body;2. arm is installed;3. notch;4. rotary angle transmitter;5. top pressure closure;6. hole;7. lead
Pipe;8. installing hole.
Detailed description of the invention
The present invention is further detailed explanation with concrete better embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of guide vane lever that can measure corner, including guide vane lever main body 1 and the installation that is connected with its side
Arm 2, described installation arm 2 is provided with the notch 3 through with guide vane lever main body 1, is provided with to detect guide vane lever in this notch 3
The rotary angle transmitter 4 of main body 1 rotational angle, described notch 3 is provided with top pressure closure 5, and this top pressure closure 5 arranges porose 6,
The conduit 7 of built-in electric wire can pass from this hole 6, and this electric wire provides power supply for rotary angle transmitter 4.Fill out between conduit 7 and hole 6
It is filled with O RunddichtringO, makes the rotary angle transmitter 4 in notch 3 seal further.
Described rotary angle transmitter 4 is preferably touch sensor, the outer wall of its guide vane lever main body 1 being fixed in notch 3
On.Rotary angle transmitter 4 can also be noncontacting proximity sensor.
Being evenly arranged with several installing holes 8 on the circumference at described guide vane lever main body 1 top, this installing hole 8 facilitates stator
The installation of arm main body 1 and dismounting.
During use, above-mentioned rotary angle transmitter 4 can accurately detect the rotational angle of guide vane lever main body 1 during use, from
And can control to lead leaf divergence easily, rotary angle transmitter 4 can be sealed in notch by top pressure closure 5, prevents outside water from entering
After, reduce the service life of rotary angle transmitter 4.
