Abstract
The utility model provides a portable device for collecting non-methane hydrocarbon sample in ambient air. The portable device comprises a box body, and is characterized in that a strap is arranged on the box body; a heat preservation layer is formed in the box body; the box body is partitioned into an un-sampled injector storing cavity and a sampled injector storing cavity by a partition plate formed in the middle part; ice bags are arranged in the un-sampled injector storing cavity and the sampled injector storing cavity respectively; an opening is formed in the box body corresponding to the upper part of the sampled injector storing cavity, an upper cover board is arranged on the opening, an outlet is formed in the box body corresponding to the lower part of the un-sampled injector storing cavity, and a lower cover board is arranged on the outlet. The device is convenient for taking, the classified storing is realized to avoid confusion, the device is convenient to carry, and the samples stored therein are free from the influence caused by external high-temperature environment.
Description
technical field:
The utility model relates to a kind of environmental monitoring utility appliance, is 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 under certain condition through solar radiation, 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 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 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 glass syringe is sealed with rubber cap, thereby the air that the material in rubber cap can penetrate in glass syringe exerts an influence to analysis result; 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.
utility model content:
The purpose of this utility model is that a kind of NMHC sample collecting apparatus of portable environment air is provided for the problem of above-mentioned existence, easy to carry, and be convenient to the syringe of taking, the syringe sampling and untapped syringe are stored classifiedly, avoid sample to obscure.
Above-mentioned object realizes by following technical scheme:
The NMHC sample collecting apparatus of portable environment air, comprise casing, on described casing, there is braces, 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 not sampling injector deposit cavity and sampling injector deposit cavity the inside and be respectively arranged with ice bag, on described casing correspondence sampling injector deposit cavity top and there is opening, on described opening, there is upper cover plate, on described casing correspondence not sampling injector deposit cavity bottom and there is outlet, in described outlet, there is lower cover.
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 utility model 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 cover lower cover, the top of sampling injector is provided with opening, sampled rear rotation upper cover plate, sampling injector is put into casing from opening part above, the syringe of taking so does not need to open casing, avoided the loss of cold in 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 utility model is taken conveniently, stores classifiedly and avoids confusion, easy to carry and be not subject to the impact of external high temperature environment on sample.
2. between upper cover plate of the present utility model and casing, adopt magnetic-type connection, it is convenient to open, and is convenient to put into syringe, and connects reliably, avoids opening voluntarily.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
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 utility model.Should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
Embodiment 1:
As shown in Figure 1: the NMHC sample collecting apparatus of portable environment air of the present utility model, comprise casing 1, on described casing, there is braces 2, described casing the inside is provided with heat-insulation layer 3, described casing by middle partition 4 be divided into not sampling injector deposit cavity 5 and sampling injector deposit cavity 6, described not sampling injector deposit cavity and sampling injector deposit cavity the inside and be respectively arranged with ice bag 7, on described casing correspondence sampling injector deposit cavity top and there is opening, on described opening, there is upper cover plate 8, on described casing correspondence not sampling injector deposit cavity bottom and there is outlet, in described outlet, there is lower cover 9.
Embodiment 2:
The NMHC sample collecting apparatus of the portable environment air described in embodiment 1, one end of described upper cover plate is connected with described casing by activity clencher 10, the other end relative with described activity clencher on described upper cover plate has magnet 11, and the correspondence position of described casing also has magnet.
Embodiment 3:
The NMHC sample collecting apparatus of the portable environment air described in embodiment 1 or embodiment 2, described lower cover is connected on described casing by hinge 12, and the other end of described lower cover has buckle 13.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
