Such as, a kind of wind gage of modified form is proposed in ZL200920004214.0, although it optimizes overall unitized construction, but still exist and adopt traditional wind-cup type to carry out this defect of air measuring, as the aforementioned, its rotating shaft of the wind gage of wind-cup type is easy to infiltrate sand and dust, and the smoothness that impact is rotated and the data precision, the wearing and tearing of vane itself also can affect the data precision to a great extent.
Meanwhile, the wind gage entirety of wind-cup type is all exposed in test environment, for the sand and dust annular that wind speed is larger, is easy to fracture or breakage.
For another example, a kind of piezoelectric anemometer of electronics is proposed at ZL200920073011.7, it is by a cylinder and in cylinder, arrange the test that a piezoelectric sensor carries out wind speed, if this kind of semi-enclosed Wind cylinder structure is for Sand Dust Environment, be easy to the accumulation that sand and dust occur, last whole air duct is blocked by sand and dust, at all cannot measuring wind, if meet with sandstone, piezoelectric sensor is also easy to break, and finally causes using.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wind gage, is a kind of novel wind pressure type wind gage, overcomes environmental resistance in prior art poor, cannot the technical matters of desertification stone.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
The utility model provides a kind of wind gage, comprises wind guide chamber, blast sensory package; Wind guide chamber comprises a cylindrical cavity, the sidewall of this cavity is provided with filter screen, top is provided with wind deflector, bottom is provided with a blast plate, and blast plate is connected with the bottom port of this cavity by an annular flexible glue circle; Blast sensory package comprises a sliding support, the top of sliding support is fixedly connected with the bottom of wind guide chamber, the bottom of sliding support is provided with a buoyancy tanks, sliding support slidably connects some floating levers, one end of floating lever is fixedly connected with blast plate, and the other end stretches in buoyancy tanks, the slip axis of floating lever and the axis being parallel of wind guide chamber, be perfused with liquid in buoyancy tanks, sliding support be also provided with an in-plane displancement sensor.
As further prioritization scheme of the present utility model, wind deflector is a dome shape wind deflector protruded to wind guide chamber inside.
As further prioritization scheme of the present utility model, blast plate comprises a dome shape windward side of protruding to wind guide chamber inside.
As further prioritization scheme of the present utility model, in-plane displancement sensor is photo-electric in-plane displancement sensor.
As further prioritization scheme of the present utility model, annular flexible glue circle is silica gel material.
As further prioritization scheme of the present utility model, the outside of sliding support is also provided with an annular expansion groove, and the bottom of annular expansion groove is communicated with by some intercommunicating pores with the bottom of buoyancy tanks.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
1, the utility model replaces traditional wind-cup type flow-velocity sensing mechanism by a blast sensing mechanism, utilizes the relational expression between wind speed and blast, can measure wind speed easily, and sensitivity is also higher; And the utility model realizes the return to floating lever by the buoyancy of liquid, more sensitive compared to spring structure, data are also more accurate;
2, the in-plane displancement sensor technology comparative maturity of photo-electric, cost compare is low, the amount of floating of floating lever just can be measured accurately by the software kit of more existing comparative maturities, by the relational expression of buoyancy and displacement of volume, just can know the pressure-bearing amount on blast plate, just wind speed can be obtained, simple and fast again by the relational expression of wind speed and blast;
3, expansion slot can prevent that the liquid of buoyancy has influence on the accuracy of data because evaporation is excessive;
