Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to defect and the problem of aviation kerosene detection artificial sampling link in prior art, a kind of sampling apparatus for flammable liquid and the methods of sampling are provided.
As shown in Figure 2, a kind of sampling apparatus for flammable liquid, comprise explosion-proof casing 11 and by interior peep the pipe 6 with described explosion-proof casing 11, be connected in peep unit 5, peep unit 5 in described and comprise temperature sensor 1, depth transducer 3, visual probe 2, sampling pipe 4 and cooling duct 12, described cooling duct 12, for being lowered the temperature to peeping unit 5 in described, is provided with display unit 8, control module 7, ground unit 10 and performance element 9 in described explosion-proof casing 11; Described control module 7 connects described ground unit 10 whether to detect ground connection, in connecting, described performance element 9 peeps unit 5, described control module 7 connects performance element 9 to carry out the sampling task, and, by interior sensor record data from the sample survey of peeping on unit 5, described control module 7 connects display unit 8 to transmit data.Described performance element 9 comprises and changes bottle and oil sample bottle.Also be provided with positive compressed-air system and vacuum pump system in described explosion-proof casing 11, described positive compressed-air system is for making the interior formation malleation of explosion-proof casing 11, and described vacuum pump system is for finding time the oil sample bottle.
As shown in Figure 1, a kind of methods of sampling for flammable liquid comprises the following steps:
Step 1, mobile sampling apparatus is to being sampled by container, and ground unit is connected to ground wire, and utilizes ground clamp to connect to be sampled container, release electrostatic; Within three seconds, open afterwards sampling apparatus positive compressed-air system, vacuum pump system, in peep unit and display unit; If ground unit does not have ground connection, control module is pointed out not work of ground unit, and system can't normally start work; After positive compressed-air system starts, the inner malleation space that forms of explosion-proof casing, preliminary work finishes.
Step 3, operating personnel's openable container, peep unit and enter container in operation.Inside peep unit and automatically in record, peep a penetration depth, the automatic transferring case internal temperature of temperature sensor; If internal temperature surpass to allow opereating specification, system auto-alarming, temp. indicator is too high.
Step 4, temperature, in allowing opereating specification, is inside peeped head and progressively enter container under operating personnel's operation, when control module detects local color, changes, and control module automatic alarm operating personnel, need sampling herein; If whole container does not have change color, control module is not reminded.
Step 5, operating personnel peep the oil sample at head's mark place in showing under controlling prompting or according to display unit, start the sampling button.Performance element under control module is controlled, the oil sample that Automatic Extraction is quantitative, temperature, sampling coding when the degree of depth, sampling that control module records this oil sample automatically.
Step 6, after primary sample completes, operating personnel press and continue sampling, and performance element is changed the oil sample bottle automatically, and after having changed, control module orders about vacuum pump this bottle is evacuated, and the display unit prompting can continue sampling.If the oil sample bottle is finished, control module is reminded and is installed the oil sample bottle additional.
The present invention possesses visual function under low-light, the low light level, by the image Compare System can the automatic decision oil sample whether qualitative change; Inside peep headband static release function, whether the control module automatic decision ground connection; Inside peep the headband automatic cooling function, peep light-source temperature in preventing too high, bring danger; Inside peep pipe and adopt anticorrosive, durable in use; Control module can record the sampling spot three-dimensional coordinate automatically; Peep unit in only needing once and probe into, can automatic sampling repeatedly; The sampling apparatus housing adopts explosion-proof casing, utilizes positive compressed-air system simultaneously, forms the malleation space, and inflammable gas can't enter inner space.
The apparatus and method of the embodiment of the present invention, can, by accurate, the intelligent management of realizing the aviation kerosene sampling observation of control module, display unit, performance element, reduce the personal error factor; The present invention can complete the work that original fully artificial means can not complete, and can effectively avoid blind and take out, and makes aviation kerosene sampling observation administrative purposes stronger, sampling observation oil sample and data are more accurate, science.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
