Description
Technical field
This utility model belongs to infrared temperature-test technology and close-shot photography measure technique field, particularly to one for spontaneous combustion
The design of coal gangue hill surface temperature field detection device.
Background technology
Gangue is the inevitable outcome in coal mining and the course of processing, is one of topmost solid waste in mining area,
According to incompletely statistics, China's gangue cumulant has reached more than 5,000,000,000 tons, a large amount of gangue air storage Cheng Shan, is up to now
Only, the whole nation there are about more than 5000 coal gangue hill piled up, due to the long-term air storage of these coal gangue hills, through exposing to the weather, rain
The effects such as water washes away make its physicochemical property change, and discharge toxic and harmful, major polluting atmosphere environment；In gangue
Heavy metal substance is discharged in soil and groundwater by the effect such as leaching, acidity, causes mining soil and underground water pollution.With
Time, the hillock of air storage is under the conditions of oxygen supply sufficiently, and internal combustible easily occurs the chemical reaction of heat release, works as heat
When running up to the burning-point of combustible, causing that hillock is internal occurs spontaneous combustion, the hillock of spontaneous combustion is susceptible to cave in, it is quick-fried and quick-fried to spray
Fried, serious threat mining area personal security, cause casualties and economic loss.
In the practice of harnessing case of more domestic self-ignition coal gangue hills, often occur that regulation effect is the best or the phenomenon of resume combustion,
Tracing it to its cause, be unclear to coal gangue hill deep combustion position and fire location, arranging even if being equipped with scientific and rational improvement
Execute, also tend to because self-ignition coal gangue hill deep fire location cannot be had any actual knowledge of so that control measures is not in place, cause merit to be lost
One basket for holding earth.Owing to the temperature of coal gangue hill deep burning things which may cause a fire disaster is delivered to coal gangue hill surface by modes such as heat transmission, make gangue
Region, surface, mountain produces temperature anomaly, and therefore, the detection of coal gangue hill surface temperature field is particularly important, and has only grasped coal
Hillock surface temperature distribution situation, positioning heat abnormal area, could propose the most hidden hazard management measure, reach
Thoroughly administer the purpose of self-ignition coal gangue hill.
Thermal infrared imager is a kind of noncontact, highly sensitive, highly reliable temperature measuring equipment, fast along with thermal infrared technology
Speed development, this technology is widely used to lossless detection, medical diagnosis, fault detect, forest fire protection, the spy of mine disguise burning things which may cause a fire disaster
The fields such as survey.Owing to all temperature are higher than the object outside radiated infrared light wave of thermodynamics zero degree, thermal infrared imager thermometry
Utilize sensor that the infrared waves wave band emittance received is converted into the signal of telecommunication, the amplified process of this signal of telecommunication, shaping
Be converted to the video signal of standard Deng process, show thermal infrared imagery finally by screen with the form of pseudo-colours.
Chinese scholars utilizes modern survey and draw technology to combine thermal infrared technology detection coal gangue hill surface temperature field (temperature field
Including temperature information and spatial information) research and field practice relatively fewer.Existing Detection Techniques are concentrated mainly on utilization
Coal gangue hill surface temperature is detected by thermal infrared imager, but this technology is only capable of obtaining the temperature image on surface, it is impossible to carry
For spatial information accurately.Along with the fast development of modern survey and draw technology, surveying and mapping technology is applied to coal gangue hill space orientation
In become a kind of trend.Carpentier.O (2005) have studied based on modern survey and draw technology GPS (global positioning system) with
Thermal infrared imager combined detection coal gangue hill surface temperature field, but be only a kind of theoretical research, do not carry out case verification with
Precision test；Temperature grid is laid in Sheng Yaobin, Wang Yunjia (2007) research on coal gangue hill surface, according to image plane and object plane
Space geometry relation, build surface temperature field, but shortcoming is the most prominent: on the one hand, owing to mesh spacing is laid big, causes
Spatial information precision is relatively low；On the other hand, if coal gangue hill surface temperature is higher, survey crew cannot arrive coal gangue hill table
Temperature grid, this suitability limiting this research method to a certain extent and feasibility are laid in face.
Close-range photogrammetry is a kind of emerging modern survey and draw technology, utilizes the big of photographic image information measurement object
The correlation measurement informations such as little, shape, locus.Close-shot photography measure technique is because of field operation strong, measuring surface simple to operate, ageing
Amass the advantages such as big, have been widely used in the mapping operations of every field.But at present, coal gangue hill surface temperature field Detection Techniques
Also it is confined to utilize single close-range photogrammetry obtain spatial information or utilize thermal infrared imaging technical limit spacing surface temperature to believe
Breath.
All in all, the Detection Techniques of existing self-ignition coal gangue hill surface temperature field there is also following deficiency:
(1) existing thermal infrared imagery searching surface temperature techniques, owing to thermal infrared imager can only obtain the temperature on surface
Information, it is impossible to obtain spatial information, usually because the erroneous judgement causing heat anomaly region cannot be accurately positioned, and then cause deep burning things which may cause a fire disaster
Location positioning failure；
(2) temperature grid is laid on existing coal gangue hill surface, according to the geometrical relationship between image plane and object plane, passes through
Spatial information interpolation, when building surface temperature field, because surface temperature is too high to lay temperature grid on surface, often leads to
The method lost efficacy.Simultaneously as the mesh spacing laid is relatively big, cause spatial information interpolation precision relatively low；
(3), during existing modern survey and draw technology searching surface temperature field, it is merely capable of obtaining spatial information, it is impossible to obtain temperature
Degree information；
(4) fail to have a kind of technology by thermal infrared imager with close shot camera unified integration on a platform, play both
Respective advantage, keeps away both respective drawbacks.
Utility model content
The purpose of this utility model be in order to overcome thermal infrared imager and the respective deficiency of close-shot photography measure technique and
Limitation, it is provided that a kind of for self-ignition coal gangue hill surface temperature field detection device, this device fully combines thermal infrared imager and obtains
Take temperature information and the advantage of close shot camera acquisition spatial information, it is achieved that the integration of two kinds of instruments, and simple in construction, it is easy to
Operation.
The utility model proposes a kind of for self-ignition coal gangue hill surface temperature field detection device, it is characterised in that this dress
Put and include close shot camera fixed mount, close shot camera, attachment means, thermal infrared imager, thermal infrared imager fixed mount and connector；Its
In, close shot camera and thermal infrared imager are respectively placed in close shot camera fixed mount and the inside of thermal infrared imager fixed mount；Close shot phase
