Abstract
The utility model discloses a rapid positioning cloud of dust sampling gun, including a sampling gun head (1a), the intermediate gun portion (1b) and a handle (1c); also including a magnet (2), which communicates with the handle through the rope wire (3); and including a positioning sealing sleeve (4) set in the intermediate gun portion, which can be moved axially along the intermediate gun portion; along the axis of intermediate gun portion is provided with a guide groove of positioning sealing sleeve (1b1); the inner hole edge of the positioning sealing sleeve (4) is provided with a positioning card block (4a), which is movably embedded in the guide groove (1b1); the outer surface of the intermediate gun portion (1b) is also provided with a series of annular slot (1b2) intersecting with the guide groove. The utility model adopts simple and reasonable structure, which can quickly and stably be positioned on the chimney; has certain tightness, and the soot inside chimney is not easy to spill from the sampling port; greatly reduces labor intensity of testing personnel.
Description
Technical field
The utility model belongs to the enviromental monitoring equipment field, relates in particular to a kind of cloud of dust sampling rifle.
Background technology
Along with the enhancing of people's environmental consciousness, some tail gas etc. of more and more paying attention to producing in the production run are monitored; Especially some boiler exhaust gas are monitored.Smoke dust sampling gun is to a kind of visual plant in the boiler cloud of dust, the fume emission test, when chimney smoke is sampled, needs the sampling rifle is put in chimney inside from the thief hatch on the chimney.The thief hatch of opium pipe and chimney is not close-fitting during sampling, can't fix with chimney, this just need be sampled by the hand-held sampling of site test personnel rifle, need carry out multi-point sampling to flue inside during simultaneously owing to sampling, the time of cost is more, increase the labour intensity of testing crew greatly, fallen into the inner phenomenon that causes boiler plant not run well of chimney thereby therefore the sampling rifle often takes place in traditional sampling process, also easily caused scald personnel's accident simultaneously.Though have structures that some can make sampling rifle location at present, this class formation is more complicated mostly, locating speed is slower.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of simple and reasonable, the cloud of dust sampling rifle that can locate fast.
For solving the problems of the technologies described above, concrete technical scheme of the present utility model is as follows:
Cloud of dust sampling rifle in a kind of quick location comprises sampling gun head, middle barral of a gun position and pikestaff; It is characterized in that: also comprise magnet, described magnet is connected with described pikestaff by rope yarn;
Comprise that also one is enclosed within the location sealing shroud at described middle barral of a gun position, described location sealing shroud can move axially along middle barral of a gun;
The barral of a gun position is provided with location sealing shroud gathering sill along its axis in the middle of described;
Also be provided with the positioning wedged block that a cross sectional shape and described gathering sill cross sectional shape are complementary on the sealing shroud endoporus limit, described location; Described positioning wedged block activity is embedded in the described gathering sill;
Also be provided with some at described intermediate bar external surface and be listed as the annular slot that intersects with described direction recess, described positioning wedged block can snap in the described annular slot.
Further, described annular slot is equidistant distribution in the intermediate bar body portion.
Further, have hole at described magnet, rope yarn ties up in the described hole.
Advantage of the present utility model is: the utility model is simple and reasonable, can be positioned on the chimney fast and stable; Have certain sealing, the flue dust in the chimney is difficult for overflowing from thief hatch; It is very convenient to operate, and greatly reduces the labour intensity of testing crew.
Description of drawings
Fig. 1 uses view for the utility model;
Fig. 2 is the utility model barral of a gun position structural representation;
Fig. 3 is the utility model location sealing shroud structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises sampling gun head 1a, middle barral of a gun position 1b and pikestaff 1c; Also comprise magnet 2, described magnet 2 is connected with described pikestaff 1c by rope yarn 3;
Comprise that also one is enclosed within the location sealing shroud 4 of described middle barral of a gun position 1b, described location sealing shroud 4 can move axially along middle barral of a gun; Barral of a gun position 1b is provided with location sealing shroud gathering sill 1b1 along its axis in the middle of described; Also be provided with the positioning wedged block 4a that a cross sectional shape and described gathering sill cross sectional shape are complementary on the described location sealing shroud 4 endoporus limits; Described positioning wedged block 4a activity is embedded in 1b1 in the described gathering sill; The barral of a gun position 1b outside surface equally spaced crossing annular slot 1b2 of a series of and described direction recess that is provided with also in the middle of described, described positioning wedged block 4a can snap among the described annular slot 1b2.
Use flow process of the present utility model is as follows: after the rifle of will sampling stretches into suitable distance from the thief hatch of chimney 5, running fix sealing shroud 4 is fitted with chimney 5 outer walls then, the rotational positioning sealing shroud 4 again, fixture block 4a on the sealing shroud endoporus of location is snapped in the corresponding annular slot 1b2, and locate sealing shroud 4 and can not move axially this moment.Because location sealing shroud 4 profiles are greater than the thieff hatch on the chimney 5, the sampling rifle can not be fallen in the chimney; Flue dust in the chimney is difficult for overflowing from thief hatch simultaneously.Thereby rifle can skid off from thieff hatch and cause sampling work normally not carry out but sample this moment, also need the rope yarn 3 on the sampling rifle pikestaff 1c is stretching and the magnet 2 of rope yarn end is adsorbed on the iron chimney 5, thereby the sampling rifle is carried out spacing, prevented the phenomenon that the sampling rifle comes off and skids off effectively.Spacing for rope yarn can firmly be carried out the sampling rifle, the piece number of magnet is generally 2 ~ 3; Rope yarn 3 is to tie up in the hole of magnet 2, is convenient to change the length of rope yarn 3 like this to adapt to the demand of different occasions.
The utility model is simple and reasonable, can be positioned on the chimney fast and stable; Have certain sealing, the flue dust in the chimney is difficult for overflowing from thief hatch; It is very convenient to operate, and greatly reduces the labour intensity of testing crew.
