Abstract
The utility model pertains to the atmosphere measurement technical field and relates to an improvement of a visibility meter. The utility model comprises a base disc 1, a post 2 and an electric control cabinet and is characterized in that a dovetail-shaped fork frame consists of a connection sleeve 5 and two support arms 7; the connection sleeve 5 and the support arms 7 are integrated by welding and the top end of each support arm 7 is provided with a fixing device for a launcher/a receiver. The utility model adopts the dovetail-shaped fork frame and transmission beams are not reflected by ground objects, thereby ensuring the accuracy of the receiver to receive scattered light energy, thus improving measurement precision.
Description
The utility model belongs to the aeromerric moasurenont technical field, relates to the improvement to visiometer.
The atmosphere visibility meter of China's use at present all is an imported product, for example the FD12 type visiometer of Vaisala Oy's production.The support of this visiometer is made up of a chassis 1, column that is connected with chassis 12, the electric cabinet 3 and the crossbeam that is fixed on column 2 upper ends that are fixed on the column 2.Transmitter and receiver are installed in the two ends of crossbeam respectively, and in order to avoid the influence of crossbeam to the emission light beam, transmitter and receiver all need a downward-sloping angle.The problem that this structure is brought is, the transmitter emitted light beams shines diffusing of forming behind the ground object and is received the device secondary probably and receives, thereby can have influence on the accuracy of the scattered energy that receiver receives, and then have influence on the accuracy of measurement result.
The purpose of this utility model provides a kind of transmitter emitted light beams chance ground object of avoiding and produces irreflexive forward scattering visiometer support, improves the precision of its measurement.
The technical solution of the utility model is, a kind of forward scattering visiometer support, comprise a chassis 1, the column 2 that is connected with chassis 1, be fixed on the electric cabinet 3 on the column 2, it is characterized in that, the crotch that is connecting a swallow-tail form in column 2 upper ends, it is by an adapter sleeve 5 that is enclosed within on the column 2, two are upturned, become the α angle with level, the support arm 7 that is positioned at same plane is formed, adapter sleeve 5 is welded as a whole with support arm 7, there is one by pallet 8 on the top of each support arm 7, terminal pad 9, the emitter/receiver stationary installation that bearing 10 and gland 11 are formed, pallet 8 welds with the upper end of support arm 7, terminal pad 9 and pallet 8 and bearing 10 are connected respectively by screw, after bearing 10 was fixed with gland 11, its inner chamber was a cylindrical shape, and the internal diameter of cylinder is slightly larger than institute's stationary transmitters/receiver, the axis of this cylinder keeps level, the axis of each cylinder becomes the β angle with the plane at support arm 7 places, and the span of α is 20 °～50 °, and the span of β is 10 °～30 °.
The utility model has the advantages that owing to adopted the crotch of swallow-tail form, transmitter and all employing levels of receiver are installed, the emission light beam can not reflected by ground object, has guaranteed the accuracy of the scattered energy that receiver receives, thereby has improved measuring accuracy.
Description of drawings.
Fig. 1 is the structure principle chart of an embodiment of the utility model.
Fig. 2 is the partial enlarged drawing that the emitter/receiver part is installed among Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Below in conjunction with accompanying drawing the utility model is elaborated.Referring to Fig. 1, entire bracket comprises a chassis 1, the column 2 that is connected with chassis 1, is fixed on the electric cabinet 3 on the column 2.Chassis 1 tightens up with column 2 usefulness screws 4.Main improvement of the present utility model is, is connecting the crotch of a swallow-tail form in column 2 upper ends, it by one be enclosed within 5, two of adapter sleeves on the column 2 that be upturned, become the support arm 7 α angle, that be positioned at same plane to form with level.When support arm 7 is made from large to small shape of vertical width from bottom to top, the center line of its vertical plane with become the α angle with level.Adapter sleeve 5 is welded as a whole with support arm 7, there is one by pallet 8 on the top of each support arm 7, the emitter/receiver stationary installation that terminal pad 9 bearings 10 and gland 11 are formed, pallet 8 welds with the upper end of support arm 7, terminal pad 9 and pallet 8 and bearing 10 are connected respectively by screw, after bearing 10 is fixed with gland 11, its inner chamber is a cylindrical shape, the internal diameter of cylinder is slightly larger than institute's stationary transmitters/receiver, the axis of this cylinder keeps level, the axis of each cylinder becomes the β angle with the plane at support arm 7 places, the span of α is 20 °～50 °, and the span of β is 10 °～30 °.Fig. 2 provides the enlarged drawing of emitter/receiver stationary installation.As shown in the figure, terminal pad 9 can adopt dormant screw 12,13 to be connected with pallet 8 and terminal pad 9 with bearing 10, with keep outer rim in the cylinder that bearing 10 and gland 11 synthesize neatly, be convenient to install emitter/receiver simultaneously.Recommending to adopt the span of α is 30 °～35 °, and the span of β is 17 °～19 °.
For the ease of arranging cable, column 2 and support arm 7 all are Cavity structural members.Up to electric cabinet 3 all have the hole that allow cable pass through adapter sleeve 5 to the inner chamber of column 2 to the inner chamber of support arm 7 and from the inner chamber of support arm 7 through terminal pad 9, pallet 8 from the synthetic cylinder of bearing 10 and gland 11.For the upper end of column 2, can leave elongated slot vertically in the position that correspondence support arm 7, until the upper surface of column 2.Be convenient to the dismounting of adapter sleeve 5 like this.
For the assembling of being more convenient for, a demountable loam cake 6 can be set in the upper end of said adapter sleeve 5, it is connected with adapter sleeve 5 by screw thread.
For the ease of the location of terminal pad 9 with pallet 8, at the center, upper surface of said pallet 8 pilot hole is arranged, center in the lower surface of terminal pad 9 has a diameter to be slightly less than the positioning cylinder of above-mentioned pilot hole, and this positioning cylinder fits in the above-mentioned pilot hole just.Terminal pad 9 also plays the role of positioning with the attachment screw of pallet 8 simultaneously, and its position is to determine according to the size at needed β angle, after terminal pad 9 and pallet 8 are coupled together, just obtains correct β angle value.
