Abstract
Then invention discloses a grease density sensor, which comprises a shell and a rotating shaft arranged in the shell, wherein an oil inlet is formed on one side of the shell. The grease density sensor is characterized in that a right-angle triangular block is arranged in the shell; the center of the right-angle triangular block is matched with the rotating shaft, so the right-angle triangular block can rotate along with the rotating shaft; the inclined surface of the right-angle triangular block is a grease receiving plate; the longitudinal surface of the right-angle triangular block is a reflecting plate; the grease receiving plate corresponds to the oil inlet; a laser is arranged in the shell; laser emitted by the laser perpendicularly irradiates on the reflecting plate; and a photoelectric receiving matrix is arranged in the shell and is used for receiving the laser reflected by the reflecting plate. The inclined surface of the right-angle triangular block which can rotate along with the rotating shaft can receive the detected oil product, so that the sensitivity is high; the laser and the photoelectric receiving matrix are used for reflecting the change of the density of the tested oil product, so that the precision is high; and the grease density sensor is simple and convenient to detect and operate, has short detection and operation time, and is not limited by the field.
Description
Technical field
The present invention relates to the electromechanical integration sensor, particularly a kind of for detection of grease density sensor.
Technical background
The detection of edible oil is the detection of puzzlement people's problem, particularly waste oil always,, due to the complicated component of edible oil, is not easy to detect the composition that whether contains waste oil in edible oil, and chemical method detection complicated operation and effect commonly used are not ideal enough.Also have and adopt spectroscopic methodology, chromatography to detect in edible oil whether to have mixed waste oil, but detection time is long, and can only detect in laboratory, can not detect at the scene, obtain a result very soon.And reality especially need to be practical, easy and simple to handle, detects edible oil checkout equipment accurately and rapidly.
Summary of the invention
The purpose of this invention is to provide a kind of grease density sensor, it is highly sensitive, and degree of accuracy is high, detects simple and efficient to handlely, is not subjected to the restriction in place.
Described a kind of grease density sensor of the present invention, comprise housing, be located at the rotating shaft in housing, in a side of housing, is provided with oil-in, it is characterized in that:
One right angle gore is located at housing Nei，Qi center and coordinates with rotating shaft, can rotate with rotating shaft; The inclined-plane of right-angle triangle piece is the grease receiver sheet, one side is reflector longitudinally; The grease receiver sheet is corresponding with oil-in;
One laser instrument is located in housing, the laser direct projection reflector that laser instrument sends;
One photoelectricity receiving matrix is located in housing, receives the laser of reflector reflection.
Described a kind of grease density sensor, its described photoelectricity receiving matrix is comprised of the photoelectric tube of a plurality of vertical arrangements.
The present invention is because detected oil product is accepted on the inclined-plane of the right-angle triangle piece by rotating with rotating shaft, and is highly sensitive; Owing to adopting laser instrument and photoelectricity receiving matrix to reflect the variation of detected oil density, degree of accuracy is high; Detect easy and simple to handlely, the time is short, and is not subjected to the restriction in place.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
A kind of grease density sensor shown in Figure 1, comprise housing 1, be located at the rotating shaft 6 in housing, in a side of housing, is provided with oil-in 7; One right angle gore is located at housing Nei，Qi center and coordinates with rotating shaft 6, can rotate with rotating shaft; The inclined-plane of right-angle triangle piece is grease receiver sheet 2, one side is reflector 3 longitudinally; Grease receiver sheet 2 is corresponding with oil-in 7; One laser instrument 5 is located in housing, the laser direct projection reflector 3 that laser instrument sends; One photoelectricity receiving matrix 4 is located in housing, receives the laser of reflector 3 reflections.
Further, described photoelectricity receiving matrix 4 is comprised of photoelectric tube BPW21 of a plurality of vertical arrangements etc.
The present invention is work like this: the laser that laser instrument 5 sends is emitted on certain photoelectric receiving tube of photoelectricity receiving matrix 4 through reflector 3, after receiving when grease receiver sheet 2 grease that enters from oil-in 7., the balance of right-angle triangle piece just changes, the position of reflector 3 also changes thereupon, and the laser that sends of laser instrument 5 reflexes on (position changes) another photoelectric receiving tube of photoelectricity receiving matrix 4 through reflector 3.Due to quality (density) difference of the oil product that enters, the angle that the right-angle triangle piece rotates is different, so the position (photoelectric tube) that photoelectricity receiving matrix 4 receives is also different.So just different oil products can have been distinguished.
Claims (2)
1. grease density sensor, comprise housing (1), be located at the rotating shaft (6) in housing, in a side of housing, is provided with oil-in (7), and it is characterized in that: a right angle gore is located at housing Nei，Qi center and coordinates with rotating shaft (6), can rotate with rotating shaft; The inclined-plane of right-angle triangle piece is grease receiver sheet (2), one side is reflector (3) longitudinally; Grease receiver sheet (2) is corresponding with oil-in (7); One laser instrument (5) is located in housing, the laser direct projection reflector (3) that laser instrument sends; One photoelectricity receiving matrix (4) is located in housing, receives the laser of reflector (3) reflection; The laser that laser instrument (5) sends is emitted on certain photoelectric tube of photoelectricity receiving matrix (4) through reflector (3), after receiving when grease receiver sheet (2) grease that enters from oil-in (7), the balance of right-angle triangle piece just changes, the position of reflector (3) also changes thereupon, the laser that sends of laser instrument (5) changes through the position that reflector (3) reflexes to photoelectricity receiving matrix (4), to another photoelectric tube; Because the density of the oil product that enters is different, the angle that the right-angle triangle piece rotates is different, so the photoelectric tube that photoelectricity receiving matrix (4) receives is also different, so just can distinguish different oil products.
2. grease density sensor according to claim 1, it is characterized in that: described photoelectricity receiving matrix (4) is comprised of the photoelectric tube of a plurality of vertical arrangements.
