Description
Technical field
The present invention relates to the vane protective cover of dismountable wind-cup type wind gage, it is the protective device of the instrument of the measuring wind of meteorological field, belongs to meteorologic instrument field.
Background technology
Wind speed is the reference data that meteorological field is conventional, as a basic parameter of meteorological research, the Accurate Determining of wind speed has great significance, if just gone wrong from anemometry, there is deviation with regard to plenary session in research below, visible Measurement accuracy wind speed has very important meaning.
Wind speed is also the weather parameters paid close attention to as people's daily life, be directly connected to the living arrangement of people, the people of nearly all concern weather forecast, also pay close attention to wind speed simultaneously, decide and arrange the life of second day, accurate forecast wind speed is necessary, otherwise the crowd paying close attention to the huge numeral of weather will be affected.
The instrument of measuring wind is wind gage, and common wind speed is in respect of wind-cup type wind gage, propeller anemometer.
Wind-cup type wind gage, its sensing part is made up of three or four taper shapes or hemispheric empty cup.Drag cup shell be fixed on be mutually 120 ° trident star-shaped support on or on cross bracket in 90 ° mutually, the concave surface of cup arranges along a direction, whole transverse arm frame is then fixed on a vertical turning axle.
When wind blows from left, the first vane is parallel with wind direction, and wind is approximately zero to the pressure of the first vane at the most straight component on vane direction of principal axis.Second vane becomes 60 degree of angles crossing with the 3rd vane with wind direction, and for the second vane, its concave surface is in face of wind, and the blast born is maximum; 3rd its convex surface of vane windward, the detour flow of wind makes wind pressure ratio second vane suffered by it little, because the second vane and the 3rd vane are perpendicular to the pressure differential on vane direction of principal axis, and make vane start clockwise direction rotation, wind speed is larger, initial pressure differential is larger, and the acceleration of generation is larger, and vane rotates faster.
After vane starts rotation, because the second vane direction is with the wind rotated, the pressure of wind-engaging reduces relatively, and the 3rd vane rotates in face of wind with same speed, suffered blast increases relatively, and leeway constantly reduces, through after a period of time (when wind speed is constant), when the partial pressure difference acted on three vanes is zero, vane just becomes does uniform rotation.The size of wind speed just can be determined like this according to the rotating speed (number of turns that p.s. turns) of vane.
When vane rotates, drive coaxial multiple tooth episcotister or bar magnet to rotate, obtained the pulse signal be directly proportional to vane rotating speed by circuit, this pulse signal, by rolling counters forward, just can draw actual wind speed value after converting.
Current Novel rotor anemometer is all employings three glasss, and the Performance Ratio of beaker flask is hemispheric good, revolving cup can increase sharply rotating speed when the wind velocity increases, to adapt to gas velocity, when wind speed reduces, due to inertia effects, rotating speed but can not decline immediately, the wind speed that rotary anemometer indicates in battle array wind is generally higher become too high effect, and the average error of generation is about 10%.Inventor finds through retrieval, application number is 201220691098.6, patent name is a kind of wind direction monitoring system for winter jujube tree, comprise wind-cup type wind gage, wind-cup type wind gage is fixed on a cradle top, frame bottom is provided with multiple support column hinged with support, support column and support junction are provided with travel switch, travel switch is connected with an alarm, described wind-cup type wind gage is connected with far-end wireless bridge, described far-end wireless bridge is wirelessly connected with a base station, described base station is connected with a switch, switch is connected with an Environment Monitoring Service device with liquid crystal display, switch and multiple client's side link.For the wind direction monitoring system of winter jujube tree, the wind speed around jujube tree can be recorded timely, and wind speed information is sent to server stores, be convenient to staff and to work accordingly adjustment according to wind speed information, for the management of later jujube tree provides foundation.Inventor thinks that such needs are arranged on outdoor for a long time, and for the winter jujube tree wind-cup type wind gage there is very large infringement hidden danger, especially the vane of wind-cup type wind gage easily damages, because installation position sets high, change pretty troublesome after damaging, and measurement result exists error, be unfavorable for correct the arranging work of people.
Application number is 201010514819.1, and patent name is wind gage, this wind gage, when not needing about empty flow directing device, measures the wind speed along any direction.Be installed as, relative to the sensor board of rigid mount motion, there is outside surface around an axis symmetrical.Wind load on load sensor senses sensor board.There is its axis of symmetry roughly arrange near sensor board with the flow deflection of the conical surface of described axis coaxle, and by incident air stream deflection sensor board.This wind gage possible in theory, but there is very large not operability in actual applications, and be especially applied in real life use, once break down, be difficult to solve, common user can not self-healing.And such wind gage cost of manufacture is high, is unfavorable for wide popularization and application.
Inventor, through a large amount of retrieval, finds still few to the research of wind-cup type wind gage at present, does not especially almost have the measure of the protection of vane, so just cause the measuring error of wind-cup type wind gage to exist always, cannot eliminate.The vane surrounding of traditional wind-cup type wind gage is provided with longitudinal protective cover, and vertical protection cover can stop the wind blowing to vane, and the wind causing vane to receive not is real natural wind speed.
