Abstract
The invention discloses a comb-shaped shading device. The shading device comprises two sensor-mounting plates, two base plates, shading teeth and a bottom plate; at least three shading teeth are respectively equidistantly and vertically fixed on one side of each base plate, the other sides of the two base plates are respectively fixed on respective sensor-mounting plates, the two sensor-mounting plates are respectively vertically mounted on both ends of the bottom plate, the numbers of the shading teeth on the two sensor-mounting plates are equal, the shading teeth are arranged inwards at the same height, and a light hole is arranged at the center between each two shading teeth. The invention can effectively shade upwardly or downwardly slanted incident flame light, and only allows the incidence of light ray at each angle, which is at the same level as a photosensitive tube, consequently, the photosensitive tube at the same height as the tip of flame still can capture light even if the flame waves to the left and the right, and thereby the precision of flame height measurement is increased.
Description
Technical field
The present invention relates to a kind of shade, particularly be used for a kind of comb-shaped shading device that flame height detects.
Background technology
Flame height adopts the intensive linear array light sensor detection technique of ccd image acquisition process technology or arranged vertical that it is implemented to detect usually, and the former sample rate is slower, and is high than the certainty of measurement of flammule to vibration frequency; Latter's sample rate is fast, cost is low, thus be widely used in online detection range, but that shortcoming is a certainty of measurement is lower.
As flame height, the reason that its accuracy of detection is lower is that the most advanced and sophisticated emergent light of flame is injected obliquely and is positioned at more high level photosensitive tube to intensive linear array light sensor, causes mistake to survey with the height of the extreme higher position photosensitive tube that can experience flame light.For accurately catching the most advanced and sophisticated true altitude of flame, just must prevent that the above arbitrary photosensitive tube of this height from receiving flame and penetrating light.Existing solution is that photosensitive tube is placed in the printing opacity through hole, shields all oblique rays, comprises horizontal skew ray.Because the most advanced and sophisticated fluctuation easily of flame, this method will shield all light when aperture is departed from the tip over against the position, make same level height photosensitive tube can not detect the flame tip, cause mistake to survey equally.
Summary of the invention
Deficiency to checkout gear in the above-mentioned background technology; The purpose of this invention is to provide a kind of comb-shaped shading device; Make that arbitrary photosensitive tube can receive the incident ray on the same level height in the linear array, shielding simultaneously obliquely or oblique incidence downwards and depart from the disturbance of aperture over against the position.
The technical scheme that the present invention adopts is:
The present invention includes two sensor installing plates, two substrates, shading teeth and base plates; The shading teeth that is at least three equidistantly is vertically fixed on a side of substrate separately respectively; Another side of two substrates is separately fixed at separately on the sensor installing plate; Two sensor installing plates are vertically mounted on the both sides of base plate respectively; High layouts such as the shading teeth number on two sensor installing plates is identical and inside, point midway has a printing opacity through hole between two shading teeth.
The present invention compares with background technology, and the beneficial effect that has is:
The present invention has effectively shielded obliquely or the oblique flame light of injecting down; Only allow to inject with each angle light of photosensitive tube same level height; Can both capture light when the photosensitive tube that is in the co-altitude position with the flame tip is fluctuateed about flame, improve the flame height accuracy of detection.
Description of drawings
Fig. 1 is a comb-shaped shading device structural principle sketch map of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is that the A-A of Fig. 1 is to sketch map.
Among the figure: 1. sensor installing plate, 2. substrate, 3. shading teeth, 4. base plate, 5. printing opacity through hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3, the present invention includes two sensor installing plates 1, two substrates 2, shading teeth 3 and base plates 4; The shading teeth 3 that is at least three equidistantly is vertically fixed on a side of substrate 2 separately respectively; Another side of two substrates 2 is separately fixed at separately on the sensor installing plate 1; Two sensor installing plates 1 are vertically mounted on the both sides of base plate 4 respectively; High layouts such as the shading teeth number on two sensor installing plates 1 is identical and inside, point midway has a printing opacity through hole 5 between per two shading teeth.
Shading teeth 3 is formed by the aluminium block Milling Process; On substrate 2, be positioned at two shading between cog point midways and have printing opacity through hole 6; Substrate 2 thickness are less, and the flame light that helps being positioned on the base plate 4 receives by 5 incidents of printing opacity through hole and by sensor installing plate 1 inner light sensor; The outer surface of shading teeth and substrate is handled through sandblast and blackout, make be radiated at shading teeth 3 sidewalls obliquely or downward most of light be absorbed and repeatedly diffuse reflection take place, thereby make the original light of finally injecting printing opacity through hole 5 very faint.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all drop into protection scope of the present invention.
