Description
Technical field
The utility model relates to the instrument of gaseous tension and fluid-velocity survey, is specifically related to a kind of anemometer of measuring the airduct air quantity.
Background technology
System's total blast volume of heating ventilation and air-conditioning system is the master control project that building energy conservation detects, because the limitation of anemoscope, when the test macro total blast volume, the main proving installation that adopts mainly is made of Pitot tube and microbarograph at present.But in test process, this kind method is usually because the distance of Pitot tube insertion airduct is inaccurate, human factors such as Pitot tube and airduct out of plumb, cause test result inaccurate, help the tester to judge whether distance, the Pitot tube of Pitot tube insertion airduct be vertical with airduct if can add servicing unit, to reduce the personal error of test, and make test result more accurate.
The utility model content
The purpose of this utility model is to provide a kind of intelligent anemometer that can accurately measure the airduct air quantity.
The purpose of this utility model is achieved by taking following technical measures:
A kind of intelligent anemometer, comprise L type standard Pitot tube, range finding probe, probe mounting disc and calculate display module, described range finding is popped one's head in and is installed in the afterbody of L type standard Pitot tube by the probe mounting disc, and the range finding probe is connected with the calculating display module by data line.
Range finding probe described in the utility model is ultrasonic ranging probe or infrared distance measurement probe.
The ultrasound wave of the utility model intelligence anemometer/infrared distance measurement probe is installed in the afterbody of L type standard Pitot tube by the probe mounting disc, calculate display module and the length that Pitot tube inserts airduct is shown, and judge whether vertically airduct of Pitot tube according to the result that ultrasound wave/the infrared distance measurement probe records.L type standard Pitot tube is the pressure parts, with the same with common Pitot tube test, is used to obtain total head and static pressure in the airduct.
Ultrasound wave/infrared distance measurement probe is used for the distance of test probe apart from the airduct surface, in order to judge whether Pitot tube is vertical with airduct, the utility model adopts the arrangement form of 4 ultrasound waves/infrared distance measurement probe circular symmetric, and whether the measured distance by two pairs of range finding probes of symmetry relatively is consistent judges whether Pitot tube is vertical with airduct.
Calculate display module and will calculate the distance that Pitot tube inserts airduct, and judge whether Pitot tube is vertical with airduct according to range finding probe feedback data, if out of plumb, the alerting signal of sounding, and the offset direction of prompting Pitot tube.
The Pitot tube of the utility model intelligence anemometer can judge that Pitot tube inserts the distance of airduct according to the distance that ultrasound wave/the infrared distance measurement probe records, thereby helps the tester can locate rapidly the different depth measurement point; Simultaneously, whether the distance that records by two pairs of probes of symmetry relatively is consistent judges that whether Pitot tube is perpendicular to airduct.Compare with the wind measuring device that microbarograph constitutes with common Pitot tube, the present invention has following advantage:
(1) this intelligence anemometer can demonstrate the distance that Pitot tube inserts airduct intuitively, makes things convenient for the location of tester to measuring point;
(2) this intelligence anemometer can judge initiatively whether Pitot tube is vertical with airduct, if out of plumb, the warning of will sounding, and prompting offset direction help the tester to adjust.
Description of drawings
Fig. 1 is the structural representation of the utility model intelligence anemometer;
Fig. 2 is the Pitot tube range finding probe mounting synoptic diagram in the utility model intelligence anemometer.
Embodiment
As shown in Figure 1, the utility model intelligence anemometer mainly is made up of L type standard Pitot tube 1, ultrasound wave/infrared distance measurement probe 2, probe mounting disc 3, data line 4 and calculating display module 5.4 ultrasound wave/infrared distance measurement probe 2a, 2b, 2c, 2d are installed in the afterbody of L type standard Pitot tube 1 with the form of circular symmetric by probe mounting disc 3, because L type standard Pitot tube 1 afterbody has the static pressure interface and points to bar, so, avoid the static pressure interface and point to bar with ultrasound wave/infrared distance measurement probe 2b and 2d parallel offset.Ultrasound wave/infrared distance measurement probe 2 is connected with calculating display module 5 by data line 4.
Because the distance that ultrasound wave/the infrared distance measurement probe records is the distance of ultrasound wave/infrared probe to airduct outside surface or insulation outside surface (during airduct band insulation material), rather than the actual distance of L type standard Pitot tube insertion airduct, the actual distance of L type standard Pitot tube insertion airduct will calculate display module and obtain by calculating.L type standard Pitot tube is inserted airduct and L type standard Pitot tube is adjacent to punching crosswind tube wall, and the distance that this moment, ultrasound wave/the infrared distance measurement probe recorded is designated as L
1And then L type standard Pitot tube inserted the airduct depths, and the distance that records this moment is designated as L
2, L then
1With L
2Difference be the true length that L type standard Pitot tube inserts airduct.Use for convenient, at the calculating display module zero key is set, when being adjacent to punching crosswind tube wall when L type standard Pitot tube insertion airduct and with L type standard Pitot tube, the tester is manually made zero, and is about to L
1Be initialized as zero, after this L type standard Pitot tube inserts any degree of depth, and calculating the display module result displayed promptly is the length that L type standard Pitot tube inserts airduct.
In the time of test, calculate display module and will judge with the distance that 2b, 2d record whether L type standard Pitot tube is vertical with airduct by comparing two groups of symmetry ultrasound waves/infrared distance measurement probe 2a, 2c, when promptly the distance that records when two ultrasound wave/infrared probes of symmetry is identical, illustrate that L type standard Pitot tube is vertical airduct; When the distance that records when two ultrasound wave/infrared probes of symmetry does not wait, illustrate that L type standard Pitot tube and airduct are off plumbs, and a side of deflection distance weak point, calculate the display module warning of will sounding at this moment, and point out offset direction.
To be that example specifies using method of the present utility model with the air quantity of test heating ventilation and air-conditioning system below:
1) determines measuring point according to the airduct size;
2) be adjacent to punching crosswind tube wall with L type standard Pitot tube insertion airduct and with L type standard Pitot tube, determine the vertical airduct of L type standard Pitot tube (out of plumb not occurring reports to the police) back zeroing;
3) according to calculating distance that display module shows with L type standard Pitot tube inserting step 1) determined position;
4) if out of plumb occurring reports to the police, then adjust, carry out reading after waiting to stablize according to prompting;
5) adopt the test of finishing all the other measuring points with quadrat method, calculate the air quantity of system.
