Abstract
The utility model relates to a boiler water-level optical-fibre remote indicator for solving the problems that the existing color camera monitor observes and monitors the boiler water-level under the environment of high position and high temperature. The boiler water-level optical-fibre remote indicator can achieve the purpose mainly by a lens group, a cattle-eye double-color water level meter, an image focusing lens, quartz optical-fiber whose diameter is 1 mm and length is 150 m, a branch prism, a focusing lens, quartz optical-fiber, and an optical spots / lines expansion device which are arranged in sequence.
Description
The double-colored water level optical fiber of boiler buphthalmos long distance viewer: be a kind of device that is used for the steam boiler drum liquid level image long-distance transmissions observation of middle and high pressure.
Because the buphthalmos two-colour fluviograph of the steam boiler that units such as generating plant and chemical industry cracking use is installed in 20 to more than 60 meters high positions apart from ground, observe ten parts of inconvenience of boiler water level, observe, monitor for solution makes things convenient for water level, adopted color TV to videotape monitor at present, but because TV camera is installed in apart from the nearer position of body of heater, be in the use down of high temperature, high humidity environment for a long time, often break down, security, poor reliability, and cost is higher.
The purpose of this utility model is the problem at above-mentioned existence, has proposed the remote liquid level viewer of a kind of optical fiber, has solved observation, the monitoring problem of present color video camera display monitor central monitoring system under high position, hot environment.
Technical solution of the present utility model:
Light source 1 incides on the buphthalmos two-colour fluviograph 3 through lens combination 2, the light that is refracted is converged on the end face that luminous point is transferred to remote silica fibre 5 by being installed in image focusing lens 4 with buphthalmos two-colour fluviograph 3 axis parallels, penetrate by remote silica fibre 5 other ends, Amici prism 6 is divided into two kinds of light to this a branch of light, focus on silica fibre 8 one end faces light that the optics point/line extender 9 shows on silica fibre 8 other ends by collector lens 7.
Advantage of the present utility model:
Boiler water level optical fiber distant surveillance utensil has the optical efficiency of biography height, and anti-electromagnetic capability is strong, the characteristics that the high temperature usability is good.
Fig. 1 is the utility model principle schematic.
Fig. 2 is the utility model optics point/line extender synoptic diagram.
Below in conjunction with accompanying drawing the utility model is further described:
The light of the pointolite that 50W Halogen lamp LED 1 sends is transformed into directional light through lens combination 2 and is incident among of buphthalmos two-colour fluviograph 3 on the eye, in the buphthalmos two-colour fluviograph 3 water and anhydrous to red arranged, the refraction angle of green glow changes, if water is arranged on the buphthalmos, then on an angle of buphthalmos, can see green glow, if it is anhydrous, then on this angle, see ruddiness, according to this principle, in this angle by loading onto image focusing lens 4, make the buphthalmos water level image of 22 millimeters of φ gather into 1 millimeter visual imaging of φ on an end face of 150 meters silica fibres 5 of diameter 1 millimeters long, on the other end, send one red, the light beam of green mixing, Amici prism 6 is divided into this Shu Guang red, green two kinds of light, focus on through collector lens 7 again, be transferred to optics point/line extender 9 with silica fibre 8, point/line extender 9 is by red, it is red accordingly that the size conversion of green energy becomes, the green glow band, if in the buphthalmos water is arranged, be full green on the then corresponding display, if it is anhydrous in the buphthalmos, on the then corresponding display is whole red, if a buphthalmos has half water or 1/4th water, then show on the Dui Ying display and be half green, half red or 1/4th green, 3/4ths redness, optics point/line extender is formed an optical attenuator by several semi-transparent semi-reflecting lens that are arranged in parallel, incident optical energy is big, then the light belt of Zhan Kaiing is long, incident optical energy is little, and then the light belt that launches is short.
Claims (2)
1, a kind of boiler water level optical fiber distant surveillance device of forming by the buphthalmos two-colour fluviograph, it is characterized in that light source 1 incides on the buphthalmos two-colour fluviograph 3 through lens combination 2, the light that is refracted is converged on the end face that luminous point is transferred to remote silica fibre 5 by being installed in image focusing lens 4 with buphthalmos two-colour fluviograph 3 axis parallels, by penetrating on remote silica fibre 5 other ends, Amici prism 6 is divided into two kinds of light to this a branch of light, focus on silica fibre 8 one end faces light that the optics point/line extender 9 shows on silica fibre 8 other ends by collector lens 7.
2, boiler water level optical fiber distant surveillance device according to claim 1 is characterized in that optics point/line extender is made up of several semi-transparent semi-reflecting lens that are arranged in parallel.
