Abstract
The invention discloses a kind of high-frequency high-precision long distance wind pressure measurement meter, comprise large pressure tube, little pressure tube, pressure scanning valve and computing machine, different pressure tap is provided with large pressure tube, gaseous tension is sent near pressure scanning valve by large pressure tube, then by the little pressure tube of adapter Bonding pressure scanning valve, pressure scanning valve transfers to computing machine after measuring the wind pressure value of each pressure tap.The present invention adopts pressure scanning valve and compound pressure tube measuring technique to survey the Pressures of large scale practical structures.This measurement mechanism structure is simple, expense is little, to survey data precision high, and due to pressure tube be the insulator of electricity, measuring equipment lightning protection effect is good.
Description
Technical field
The present invention relates to a kind of high-frequency high-precision long distance wind pressure measurement meter.
Background technology
Wind can't neglect towering house, the isostructural effect of bridge tower, and the measurement of current structure blast generally adopts differential pressure gauge to measure.When adopting differential pressure gauge to carry out the effect of measurement wind, each differential pressure gauge only can survey the leeway of two points.Adopt and carry out wind pressure measurement in this way, dozens of differential pressure gauge is just needed to a section of structure, and need to select same multichannel data acquisition system (DAS), expend huge.This metering system needs to process each reference edge of dozens of differential pressure gauge, and identical to ensure the wind pressure value of reference edge, this point is often difficult to accomplish, is thus difficult to ensure that measurement result is accurate.When adopting differential pressure gauge to carry out the effect of measurement wind, each differential pressure gauge needs power supply, and in long measuring process, thunder and lightning usually can damage all electronic equipments and differential pressure gauge, causes huge property loss, and damages the data gathered.
Pressure scanning valve is a kind of commercially available prod, is generally applied to wind tunnel laboratory measurement model Pressures.Its measuring point is many, and a module just has 64 measuring points, and sampling is fast, and has a common reference point.But each measuring point of pressure scanning valve is little, and pressure transmission caliber is little, can only survey in-plant blast, during long distance pressure transmission, because decline of pressure is fast, measurement result is inaccurate.Therefore, existing pressure scanning valve can not measure the Pressures of large scale practical structures.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of high-frequency high-precision long distance wind pressure measurement meter is provided, adopts pressure scanning valve and compound pressure tube measuring technique to survey the Pressures of large scale practical structures.
The technical solution used in the present invention is: a kind of high-frequency high-precision long distance wind pressure measurement meter, it is characterized in that: comprise large pressure tube, little pressure tube, pressure scanning valve and computing machine, different pressure tap is provided with large pressure tube, gaseous tension is sent near pressure scanning valve by large pressure tube, then by the little pressure tube of adapter Bonding pressure scanning valve, pressure scanning valve transfers to computing machine after measuring the wind pressure value of each pressure tap.
The present invention adopts pressure scanning valve and compound pressure tube measuring technique to survey the Pressures of large scale practical structures.This measurement mechanism structure is simple, expense is little, to survey data precision high, and due to pressure tube be the insulator of electricity, measuring equipment lightning protection effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, in the present embodiment, high-frequency high-precision of the present invention long distance wind pressure measurement meter is applied to the measurement of pontic blast.At the bottom of bridge tower, bridge floor, bridge, pressure tap is set.(1) need the place of work high above the ground at bridge tower 17 etc., adopt rigid hollow pressure tube 1, it is fixed on bridge tower structure by upper end, avoids acting on outward at tower.Rigid hollow pressure tube 1 upper end chock plug 2 seals, lower ending opening, can ensure that in rigid hollow pressure tube, atmospheric pressure equals the blast at lower ending opening place, perforate at its upper end, be connected with large pressure tube 4 with joint 3, just can measure the blast at rigid hollow pressure tube lower ending opening place; (2) for bridge floor wind pressure measurement, bridge floor 8 arranges the delta-ring 7 be welded by multilayer steel plates, the cover plate of delta-ring 7 is opened pressure transmission hole 5, communicate with the little pressure interconnecting device 6 be enclosed in delta-ring, little pressure interconnecting device 6 is connected with large pressure tube 4; (3) for wind pressure measurement at the bottom of bridge, arrange cover plate 9 rectification for the bottom surface of decking and side, on the cover board open large pressure transmission hole 11, large pressure transmission hole 11 is connected with large pressure interconnecting device 10, is connected by large pressure tube 5 with large pressure interconnecting device 10; Gaseous tension is sent near pressure scanning valve 14 by large pressure tube 4, is connected the little pressure tube 15 of scanning valve, the then wind pressure value of each pressure tap of pressure scanning valve 14 Fast Measurement, and transfer to computing machine 12 by data line 13 by adapter 16.
Be more than a kind of specific embodiment of the present invention but not scope is whole, all equivalents done in scope of the present invention all will within scope.
