Abstract

A dust monitoring device comprising a stand (12), two open-topped buckets (16.1 and 16.2), and a cover member (18). The buckets are supported in a cradle on the stand at a predetermined height, and are placed upwind-downwind in relation to each other. The cover member includes a cover body (52) which is mounted to the stand above the buckets so as to be freely rotatable relative to the buckets. The cover body includes an aperture (60) and an upright fin (56), which is acted upon by a prevailing wind, causing the cover body to assume an orientation wherein the upwind bucket is uncovered while the downwind bucket is covered. Thus precipitation of airborne dust from two opposing prevailing wind directions can be collected in the buckets and measured.

Description

A DUST MONITORING DEVICE
FIELD OF THE INVENTION
THIS INVENTION relates to a dust monitoring device.
It relates particularly to a dust monitoring device for monitoring airborne dust.
SUMMARY OF THE INVENTION
According to the invention there is provided a dust monitoring device for monitoring airborne dust, comprising
at least one pair of open-topped dust collection receptacles in which precipitating airborne dust can be collected;
stand means for supporting the dust collection receptacles at a predetermined elevated height above ground and in an orientation wherein the receptacles are located in the path of two prevailing winds blowing in opposite directions; and a cover member that is located above the dust collection receptacles, in an arrangement permitting free rotation of the cover member relative to the receptacles in a substantially horizontal plane, the cover member defining an aperture and including an upright fin that can be acted upon by a prevailing wind for causing rotation of the cover member relative to the receptacle, into an orientation wherein the aperture of the cover member is disposed above the opening of a particular receptacle that is disposed upwind, thereby opening the upwind receptacle and simultaneously closing the downwind receptacle, in use.
The cover member may comprise a disk-like cover body which defines said aperture and which has a generally planar upper surface, the fin extending perpendicularly relative to the upper surface of the cover body.
The cover body of the cover member may be convexly curved at least at peripheral edges thereof, thereby to define an aerofoil surface which causes an increase in the velocity of air travelling over the cover body, in use, while at the same time creating a lower pressure zone over the cover body, which assists in preventing the precipitation of airborne grits and sand particles into the upwind dust collection receptacle, in use.
The cover member may be mounted to the stand means, the stand means having a bush at an upper end thereof and the cover member having a spindle that is rotatably received in the bush.
The dust monitoring device may include two pairs of dust collection receptacles, the stand means supporting the receptacles at a predetermined elevated height above ground and in an orientation wherein each pair of receptacles is disposed in the path of two prevailing winds blowing in opposite directions. BRIEF DESCRIPTION OF THE DRAWINGS
Further features of the invention are described hereinafter by way of a non-limiting example of the invention, with reference to and as illustrated in the accompanying diagrammatic drawings. In the drawings:
Figure 1 shows a schematic exploded perspective view of a dust monitoring device in accordance with the invention;
Figure 2 shows a schematic fragmentary side elevation of the dust monitoring device of Figure 1 ; and
Figure 3 shows another embodiment of a dust monitoring device in accordance with the invention.
DETAILS DESCRIPTION OF THE DRAWINGS
With reference to Figures 1 and 2 of the drawings, a dust monitoring device in accordance with the invention, is designated generally by the reference numeral 10. The dust monitoring device 1 0 comprises, broadly, a stand 1 2, a cradle 1 4, a pair of dust collection receptacles referred to hereinafter as "buckets" 1 6.1 and 1 6.2 and a cover member 1 8.
The dust monitoring device 10 is used to monitor levels of precipitating airborne dust emanating from a given direction. As such, the dust monitoring device 1 0 permits monitoring of levels of airborne dust in accordance with the ASTM 1 982 "Standard Method for Collection and Analysis for Dust Fall (settleable particulates)" with equivalent European and DIN standards. The stand 1 2 comprises a hollow pipe stanchion 20, a support base 22 and a support platform 24 that is rotatably mounted to the pipe stanchion 20 at a top end thereof.
The support base 22 comprises a hollow tubular section 26, four leg sections 28 that extend radially from a lower end region of the tubular section 26 for supporting the tubular section 26 in an upright position on a level ground surface, and four stays 30 that each extend between the tubular section 26 and a particular leg 28. The legs 28 define apertures 32 at ends thereof through which pegs or the like, can pass for securing the support base to a ground surface.
The external diameter of the pipe stanchion 20 is slightly smaller than the internal diameter of the tubular section 26 and as such, a lower end region of the pipe stanchion 20 is received within the tubular section 26. The tubular section 26 and the pipe stanchion 20 define complementary apertures 34 that are in register when the pipe stanchion is located in the tubular section 26 of the support base and in which a locating pin (not shown) is received for fixedly locating the pipe stanchion with respect to the support base.
The support platform 24 defines a number of holes and the cover member 1 8 defines a number of complementary holes in which fasteners can be received when the holes are in register, for releasably fastening the cover member to the support platform 24. The support platform 24 has a spindle 36 that is rotatably received within the pipe stanchion 20 at the top end thereof. As such, the stanchion 20 includes a bush 38 at its top end, in which the spindle 36 is rotatably received. The cradle 14 comprises a cradle body 40 having a tubular sleeve 42, and two bucket holders 44 in which the buckets 1 6.1 and 1 6.2 are received. The sleeve 42 of the cradle body 40 defines an aperture 46 and the pipe stanchion 20 defines a complementary aperture 47 in which a locating pin that is connected to the cradle body 40 via a tether chain 50, can be received when the apertures are in register, for fixedly locating the cradle with respect to the pipe stanchion. The pipe stanchion defines an aperture (not shown) lower down along its length which permits the cradle to be releasably located with respect to the stanchion at a lower height for conveniently working with the cradle and/or the buckets.
The cover member 1 8 comprises a disc-like cover body 52 having an upper surface 54, and an upright fin 56 that has a mounting plate 58 for attaching the fin to an upper side of the cover body. The mounting plate 58 and the cover body 52 define complementary apertures in which suitable fasteners can be received for fastening the fin 56 to the cover body 52. The cover body 52 defines a single round aperture 60 having a diameter roughly equivalent to the diameter of the openings of the buckets 1 6.1 and 1 6.2. The upper surface 54 of the cover body 52 has a generally planar configuration, with peripheral edges thereof being convexly curved thereby to define a peripheral edge region having the properties of an aerofoil.
In use, the dust monitoring device 1 0 permits levels of airborne dust emanating from two opposing wind directions, to be monitored. The dust monitoring device will typically be set up so that the buckets 1 6.1 and 1 6.2 are in the path of prevailing winds blowing in opposite directions. Thus, when the wind blows, one of the buckets will be upwind and the other downwind. The fin 56 of the cover member 1 8 is acted upon by the prevailing wind causing rotation of the cover member relative to the buckets. As the wind blows in one of the wind directions for which the dust monitoring device has been set up, the aperture 60 is brought into register with the opening of the upwind bucket, with the other bucket being closed by the cover member. When the wind blows in the opposite direction, the previously closed bucket is then opened when the aperture 60 is brought into register with the opening of the bucket and the previously open bucket is closed by the cover member. For example, in a location where the prevailing winds blow in south -easterly (SE) and north-westerly (NW) directions, the buckets are placed in alignment with the wind directions. Thus, a line drawn from one bucket to the other will be in a NW-SE direction. When the wind blows from the south-east, the fin will align with the south-east wind, and cause the downwind bucket to be covered, while the upwind bucket is uncovered. Dust emanating from the south-east will then be captured in this upwind bucket. In the case of a north-westerly wind the other (now upwind) bucket is uncovered and captures precipitating dust borne by the north-westerly wind. In this way, airborne dust emanating from two opposing wind directions can be collected in the upwind buckets, to be monitored.
The height of the cradle 14 above ground is regulated by the ASTM 1 982 standard, however, at wind velocities exceeding 3m/s, grits and sand particles having sizes up to approximately 0.5mm which are not to be monitored, can be lifted and conveyed to the height of the buckets. The peripheral edge region of the cover body has a shape and configuration which provides properties equivalent to that provided by an aerofoil. With reference to Figure 2 of the drawings, wind flow lines are shown by arrows A. Due to the edge profile of the cover body, the wind velocity over the cover body in the region of the aperture 60 increases with a corresponding decrease in the pressure over this region, thereby preventing the deposition of the aforesaid grits and sand particles in the upwind bucket at wind velocities exceeding 3m/s. After the wind velocity decreases to below 3m/s, undesirable grits and sand particles will not be conveyed at the level of the buckets and fall-out dust is then captured in the buckets, which can be monitored. The Applicant envisages that distilled water will be used as a capture medium for capturing fall-out dust. In order to prevent the build-up of algae in the distilled water, the Applicant envisages that a fungicide can be used in the water when sampling over longer periods than one week. Once the water/dust has been filtered through a pre-weighed filter, the dust sample can be desiccated and weighed.
With reference to Figure 3 of the drawings, another embodiment of a dust monitoring device in accordance with the invention, is designated generally by the reference numeral 1 00. The dust monitoring device 100 is similar to the dust monitoring device 10, with a difference being that the dust monitoring device 1 00 has two pairs of dust collection buckets for monitoring fall-out dust. The dust monitoring device 100 is thus particularly suitable for monitoring fall-out dust borne by prevailing winds blowing in each of two pairs of opposing wind directions. Features of the dust monitoring device 1 00 that are the same as and/or similar to those of the dust monitoring device 10, are designated in Figure 3 of the drawings by the same and/or similar reference numerals. It will be appreciated, however, that different numbers of dust collection buckets may be utilised depending on the prevailing wind directions.
The Applicant believes that the dust monitoring device in accordance with the invention, provides a simple, low-maintenance, yet effective device for monitoring fall-out dust.
