Background technology
In the coal-burning boiler of fuel-burning power plant; Combustion case in the burner hearth has great importance to security, the economy of boiler operatiopn; Particularly the burner hearth internal combustion occurs that eccentricity of fire, flame are whitewashed a wall, when heating surface coking etc. influences the situation of safe operation of the boiler, the grasp directly perceived of stove internal combustion situation is seemed particularly important; In addition, stove internal combustion situation also can provide strong reference and guidance for combustion adjustment test.
At present, mainly be to adopt hard-wired high temperature camera head auxiliary to the grasp directly perceived of burner hearth internal combustion situation with the artificial observation mode, the high temperature camera head hole of will making a video recording is fixedly mounted on certain position of furnace wall, and camera system directly connects display device; Artificial observation then is with the naked eye to carry out Direct observation through a plurality of flame-observing holes of burner hearth.The weak point of above-mentioned technology is; 1, the installation site, shooting hole of high temperature camera head is fixed, and can only keep watch on the combustion case in its angular field of view, and dirigibility is not enough; Observed efficiency is low; 2, artificial observation exists that personal injury hidden danger, visual angle are limited, observations can't be reproduced, and seriously relies on defectives such as artificial experience, and practicality is low.
The utility model content
The purpose of the utility model is to provide a kind of dirigibility high according to the weak point of prior art, the portable high temperature endoscopic system that observed efficiency is high.
The utility model is realized through following approach:
Portable high temperature endoscopic system, its structural feature are, include video camera, have protective cover, camera, cooling device and the display system of protrusive tube; Video camera is installed in the protective cover inner chamber, and camera is electrically connected with video camera, and is installed in the protrusive tube of protective cover; Cooling device is connected and is communicated with the connector of protective cover; The data-interface of video camera is connected with display system, and the protrusive tube of protective cover can stretch in the burner hearth flame-observing hole, and caliber cooperates with the flame-observing hole internal diameter is movable.
Cooling device provides cooling air to send in the protective cover inner chamber via connector, in order to cooling video camera and camera, prevents temperatures involved video camera and camera.The protrusive tube of protective cover can directly stretch in the flame-observing hole of burner hearth; With the space between caliber and the flame-observing hole internal diameter is the activity space of swing protrusive tube, and the camera that is arranged in the protective cover protrusive tube so just can be at the wider burner hearth combustion position of hunting range observation of protrusive tube; On the other hand, because the protrusive tube of protective cover is not fixedly mounted in the burner hearth flame-observing hole, be a kind of portable set; Can stretch in any flame-observing hole the observation point of realizing burner hearth internal combustion situation according to the observation needs, carry, observe dirigibility high, observation scope greatly and at random; Thereby observed efficiency is high; Effectively utilize the flame-observing hole of burner hearth itself, realized observing stove internal combustion situation flexibly, had important application value.
The utility model can further be specially:
Cooling device includes pressure-resistant rubber hose, oil and water filters and compressed air source, is connecting pipe with the pressure-resistant rubber hose, and compressed air source is connected in the connector of protective cover through oil and water filters.
Compressed air source via the oil and water filters elimination to influential oil content of electrical equipment and moisture after, can send in the protective cover, the cooling air source is provided.Have interlayer and vent port on the protective cover, the pressurized air of process oil and water filters is discharged at the vent port place of interlayer front end after getting into interlayer through connector, forms the gas wall, thereby the video camera in the protective cover is cooled off.
Display system comprises vision cable line, X-over and computer processor, and the output terminal of video camera is connected to X-over through the vision cable line, and X-over is connected to computer processor through a kind of data line.
Video camera of the prior art all is directly to adopt video line to be connected on the display, is uninterruptedly observed by the observation personnel then, can't realize record and storage.The utility model has solved the problems referred to above through computer processor: the digital signal of at first exporting in the video camera connects and is sent in the computer processor through X-over to be handled; In computer processor, write down and memory data signal then; Can select video recording or screenshotss; Can reproduce the combustion case of burner hearth, and form historical data, help boiler internal combustion situation is carried out systematic analysis; Further adjust boiler operating state, for safe operation of the boiler provides strong reference and guidance.
Camera is a kind of pinhole cameras, and it is installed in the front end of protective cover protrusive tube.
Also include a kind of instrument control box; It includes induction installation, treating apparatus, display device and warning device; Induction installation is installed on the video camera and camera in the protective cover; And be connected with treating apparatus, display device and warning device are connected respectively to the output interface and the trigger interface of treating apparatus.
The instrument control box is gathered the video camera and the working temperature of camera in the protective cover, after handling through treating apparatus, outputs to display device, when temperature above setting value, then treating apparatus also triggers warning device and sends the sound and light alarm signal.
In sum; The utility model provides a kind of portable high temperature endoscopic system; Adopt the protrusive tube of protective cover directly to stretch in the flame-observing hole of burner hearth; With the space between caliber and the flame-observing hole internal diameter is the activity space of swing protrusive tube, and the camera that is arranged in the protective cover protrusive tube so just can be at the wider burner hearth combustion position of hunting range observation of protrusive tube; On the other hand, because the protrusive tube of protective cover is not fixedly mounted in the burner hearth flame-observing hole, be a kind of portable set; Can stretch in any flame-observing hole the observation point of realizing burner hearth internal combustion situation according to the observation needs, carry, observe dirigibility high, observation scope greatly and at random; Thereby observed efficiency is high; Effectively utilize the flame-observing hole of burner hearth itself, realized observing stove internal combustion situation flexibly, had important application value.
Specific embodiment
