Abstract
The utility model relates to a portable measuring instrument for measuring the starting wind of a wind sensor, which is composed of a base, an upper cover, a direct current fan, a guide sleeve and a wind meter. The instrument is made into a portable circular body, wherein the lower part of which is provided with a wind inlet which is provided with the direct current fan and the inner part of which is provided with the guide sleeve which is provided with an inclined through groove with same direction at the upper part. The upper cover is provided with a wind outlet and the wind meter is arranged in the wind outlet or the wind meter is arranged on the base. When the instrument works, the wind sensor is arranged in the base and a direct current electric motor starts up, forming rotary air current through the inclined groove of the guide sleeve to drive the wind sensor to rotate. The starting wind of the wind sensor can be measured through the wind meter. The instrument has the characteristics of simple structure, small volume, on-site use, high precision, etc.

Technical field
The utility model belongs to the surveying instrument class, relates in particular to meteorologic survey instrument class.
Background technology
Air velocity transducer is a kind of highly sensitive, strict meteorologic instrument, after a period of time of working usually, carry out the calibration of starting wind velocity and detect its precision.Conventional method is that air velocity transducer is delivered to country or provincial measurement unit, adopts wind-tunnel to test, and is very time-consuming, costly.
Summary of the invention
The purpose of this utility model provides a kind of portable surveying instrument of measuring wind sensor starting wind velocity, is directly used in the different location, the accuracy requirement of different in-site measurement air velocity transducer starting wind velocities.
The purpose of this utility model is achieved in that
1, a kind of portable surveying instrument of measuring wind sensor starting wind velocity is made of base, loam cake, dc fan, orienting sleeve, anemometer, it is characterized in that the bottom of loam cake is shaped on air inlet and dc fan is housed; Orienting sleeve is housed in the base, is shaped in the same way tiltedly groove on the orienting sleeve; The top of base is fitted with loam cake; On cover and be shaped on air outlet, and anemometer is housed.
2, a kind of portable surveying instrument of measuring wind sensor starting wind velocity is made of base, loam cake, dc fan, orienting sleeve, anemometer, it is characterized in that the bottom of loam cake is shaped on air inlet and dc fan is housed; Orienting sleeve is housed in the base, is shaped in the same way tiltedly groove on the orienting sleeve; The top of base is fitted with loam cake, on cover and be shaped on air outlet; Anemometer is housed in the base.
Because the utility model has adopted above technical scheme.Thereby it is little to have a volume simple in structure, easily makes the measuring accuracy height, and on-the-spot result of use is good, characteristics such as economy.
Description of drawings
Fig. 1 is a kind of shape and structure synoptic diagram of the present utility model;
Fig. 2 is the orienting sleeve shape and structure synoptic diagram among the utility model Fig. 1;
It on Fig. 3 another kind of shape and structure synoptic diagram of the present utility model.
Among the figure: 1, base, 2, loam cake, 3, dc fan, 4, orienting sleeve, 5, anemometer, 6, air velocity transducer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described as follows: in Fig. 1, Fig. 2, base (1) can be made into the garden body, and the top of base (1) is fitted with loam cake (2), and it can adopt plastics or metal material to make.The bottom of loam cake (2) is shaped on an air inlet, and there is dc fan (3) at its air inlet place by screw device; Dc fan (3) also can adopt other controlled motor, as stepping, servomotor etc.Device has orienting sleeve (4) in the base (1), and the top of orienting sleeve is shaped on skew notch in the same way, and its notch quantity can be the 8-30 bar, but with the 16-20 bar for well; The below of orienting sleeve is shaped on a debugging hole, and its aperture generally can be the 3-50 millimeter for well; It can be made loam cake (2) by the transparent material of plastics or glass type; Its top be shaped on an air outlet, and at the air outlet place or other position device anemometer (5) is arranged; Anemometer (5) can adopt digital low speed impeller anemometer.
In Fig. 3, it is barrel-shaped that loam cake (2) can be made the garden cover by transparent material, and its top also has several air outlet openings.Anemometer (5) device is in base (1), and it can adopt hot-bulb formula anemometer.Hot-bulb formula anemometer also can be contained on the orienting sleeve (4).The position of dc fan (3), orienting sleeve shapes such as (4), material, device is as described in Fig. 1, Fig. 2.
When the utility model uses, earlier air velocity transducer (6) is seated in the base (1), installs loam cake (2).Then connect direct supply and start dc fan (3), form distinguished and admirablely, the skew notch through orienting sleeve (4) top forms swirling eddy in the body of the garden of base and loam cake.Its DC voltage is slowly regulated from low to high during test, and is observed the rotation of air velocity transducer by transparent upper cover (2).When DC voltage is adjusted to swirling eddy and can rotates air velocity transducer continuously, stop to regulate DC voltage, at this moment, anemometer (5) data presented is the starting wind velocity of air velocity transducer (6).During measurement, each air velocity transducer (6) should be measured 3-5 time, gets its mean value, is the accurate measured value of the starting wind velocity of air velocity transducer.
