Abstract
The invention provides a portable collecting device for non-methane total hydrocarbon samples in ambient air. The device includes a box body, which is characterized in that straps are arranged on the box body; a thermal insulating layer is arranged inside the box body; the box body is divided into an unsampled injector storing chamber and a sampled injector storing chamber through a partition in the middle; ice bags are arranged inside the unsampled injector storing chamber and the sampled injector storing chamber respectively; an opening is formed in the box body corresponding to the upper part of the sampled injector storing chamber; an upper cover plate is arranged on the opening; an outlet is formed in the box body corresponding to the lower part of the unsampled injector storing chamber; and a lower cover plate is arranged on the outlet. The portable collecting device enables the taking to be convenient, avoids mixing as sorted storage is adopted, and is portable and not influenced by the external high-temperature environment on samples.
Description
Technical field:
The present invention relates to a kind of environmental monitoring utility appliance, be specifically related to a kind of NMHC sample collecting apparatus of portable environment air.
Background technology:
NMHC (non methane total hydrocarbon, NMHc) is the general name that is present in all hydrocarbons except methane in surrounding air.NMHC in atmosphere surpasses finite concentration, except directly health being harmful to, can also produce photo-chemical smog through solar radiation under certain condition, and environment and the mankind are worked the mischief.The domestic sampling work about surrounding air NMHC parameter is substantially all to adopt glass syringe to collect air sample at present, then, with the rubber cap sealing, analyzes the same day as far as possible.Because general non-methane sample sampled point is more, with plastic crate, carry out the needle tubing transportation.The problem that this sampling apparatus exists has: at heat, and in the situation that sample can not be analyzed the same day, if now with rubber cap, glass syringe is sealed, thereby the air that the material in rubber cap can penetrate in glass syringe exerts an influence to analysis result; The plastics large bamboo or wicker basket transports the syringe of sampling in addition and unsampled syringe is mixed puts, and easily causes sample to obscure, and even occurs that some syringes are repeated to utilize the situation of sampling, have a strong impact on the accuracy of sampling.
Summary of the invention:
The objective of the invention is to provide for the problem of above-mentioned existence a kind of NMHC sample collecting apparatus of portable environment air, easy to carry, and be convenient to the syringe of taking, the syringe and the untapped syringe that sampled are stored classifiedly, avoid sample to obscure.
Above-mentioned purpose realizes by following technical scheme:
The NMHC sample collecting apparatus of portable environment air, comprise casing, there is braces on described casing, described casing the inside is provided with heat-insulation layer, described casing by middle partition be divided into not sampling injector deposit cavity and sampling injector deposit cavity, described for sampling injector not deposit cavity and sampling injector deposit the cavity the inside and be respectively arranged with ice bag, on described casing correspondence sampling injector deposit cavity top and there is opening, there is upper cover plate on described opening, on described casing correspondence not sampling injector deposit the cavity bottom and there is outlet, there is lower cover in described outlet.
The NMHC sample collecting apparatus of described portable environment air, one end of described upper cover plate is connected with described casing by activity clencher, the other end relative with described activity clencher on described upper cover plate has magnet, and the correspondence position of described casing also has magnet.
The NMHC sample collecting apparatus of described portable environment air, described lower cover is by gemel connection on described casing, and the other end of described lower cover has buckle.
Beneficial effect:
The present invention by dividing plate by sampling injector and not sampling injector store classifiedly, avoid confusion.The bottom of sampling injector is not provided with outlet, as long as opening lower cover in the time of need to taking will have syringe and automatically fall, then covering lower cover gets final product, the top of sampling injector is provided with opening, sampled rear rotation upper cover plate, sampling injector is put into to casing from top opening part, the syringe of taking does not so need to open casing, avoided the loss of cold in the casing, owing to being provided with ice bag and heat-insulation layer in casing, so the state of box house in a relative low temperature, thereby avoided the air that under high temperature, the material in rubber cap can penetrate in glass syringe to exert an influence to analysis result, generally speaking the present invention takes conveniently, stores classifiedly and avoids confusion, easy to carry and be not subject to the impact of external high temperature environment on sample.
2. adopt magnetic-type the connection between upper cover plate of the present invention and casing, it is convenient to open, and is convenient to put into syringe, and connects reliably, avoids opening voluntarily.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In figure: 1, casing, 2, braces, 3, heat-insulation layer, 4, cut off, 5, sampling injector is not deposited cavity, 6, sampling injector is deposited cavity, 7, ice bag, 8, upper cover plate, 9, lower cover, 10, activity clencher, 11, magnet, 12, hinge, 13, buckle.
Embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.Should understand following embodiment only is not used in and limits the scope of the invention for the present invention is described.
Embodiment 1:
