Abstract
The invention discloses a guide vane lever capable of measuring a rotation angle. The guide vane lever comprises a guide vane lever body and a mounting arm. The mounting arm is connected with one side of the guide vane lever body, a notch which is communicated with the guide vane lever body is formed in the mounting arm, a rotation angle sensor which is used for detecting the rotation angle of the guide vane lever body is arranged in the notch, a sealing top cover is arranged on the notch, a hole is formed in the sealing top cover, and a guide tube with a built-in electric wire can penetrate the hole. The rotation angle sensor is a contact sensor, is fixed onto the outer wall of the guide vane lever body and is arranged in the notch. The guide vane lever with the structure has the advantages that the rotation angle of the guide vane lever body can be accurately detected by the rotation angle sensor in service procedures, so that the opening of a guide vane can be conveniently controlled; the rotation angle sensor can be sealed in the notch by the sealing top cover, and accordingly the problem that the service life of an existing rotation angle sensor is shortened after external water flows into the existing rotation angle sensor can be solved.
Description
Technical field
The present invention relates to a kind of guide vane lever, particularly a kind of guide vane lever that can measure corner.
Background technology
The rotational angle of guide vane lever is being controlled and is being led leaf divergence, therefore most important to the detection of guide vane lever rotational angle.At present, after guide vane lever machines, generally can do the detection of a guide vane lever rotational angle, be mainly utilize with the connecting rod of pointer, the angle that manual observation is rotated, detects loaded down with trivial details, fiduciary level is low, and cannot detect the rotational angle of guide vane lever in actual use procedure.
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 provide a kind of simple in structure, to measure fiduciary level high, and can measure the guide vane lever that can measure corner of rotational angle in use procedure.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of guide vane lever that can measure corner, comprise guide vane lever main body and the hold-down arm being connected with one side, on described hold-down arm, be provided with the notch connecting with guide vane lever main body, in this notch, be provided with to detect the rotary angle transmitter of guide vane lever main body rotational angle, on described notch, be provided with top pressure closure, on sealing top cover, arrange porosely, the conduit of built-in electric wire can pass from this hole.
Described rotary angle transmitter is touch sensor, and it is fixed on the outer wall of the guide vane lever main body in notch.
On the circumference at described guide vane lever main body top, be evenly provided with several mounting holes.
Between described conduit and hole, be filled with O RunddichtringO.
The present invention adopts after said structure, above-mentioned rotary angle transmitter can accurately detect the rotational angle of guide vane lever main body in use procedure, thereby can control easily and lead leaf divergence, top pressure closure can be sealed in rotary angle transmitter in notch, after preventing that outside water from entering, the serviceable life of reducing rotary angle transmitter.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that can measure the guide vane lever of corner of the present invention.
Wherein have: 1. guide vane lever main body; 2. hold-down arm; 3. notch; 4. rotary angle transmitter; 5. top pressure closure; 6. hole; 7. conduit; 8. mounting hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 1, a kind of guide vane lever that can measure corner, comprise guide vane lever main body 1 and the hold-down arm 2 being connected with one side, on described hold-down arm 2, be provided with the notch 3 connecting with guide vane lever main body 1, in this notch 3, be provided with to detect the rotary angle transmitter 4 of guide vane lever main body 1 rotational angle, on described notch 3, be provided with top pressure closure 5, on sealing top cover 5, arrange 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.Between conduit 7 and hole 6, be filled with O RunddichtringO, further make rotary angle transmitter 4 sealings in notch 3.
Described rotary angle transmitter 4 is preferably touch sensor, and it is fixed on the outer wall of the guide vane lever main body 1 in notch 3.Rotary angle transmitter 4 can be also non-contacting sensor.
On the circumference at described guide vane lever main body 1 top, be evenly provided with several mounting holes 8, this mounting hole 8 facilitates the installation and removal of guide vane lever main body 1.
During use, above-mentioned rotary angle transmitter 4 can accurately detect the rotational angle of guide vane lever main body 1 in use procedure, thereby can control easily, leads leaf divergence, and top pressure closure 5 can be sealed in rotary angle transmitter 4 in notch, after preventing that outside water from entering, the serviceable life of reducing rotary angle transmitter 4.
