Background technique
It is currently anti-in the main problem of the widely applied wind detection sensor in surface weather observation field such as vane weather vane type
It is insufficient that environment capability of influence, especially anti-ice freeze capability of influence: the mechanical structure of vane weathercock is mainly by wind sense component and rotation
Axis is constituted, and in frost prone areas, freezing on wind sense component and rotary shaft, which will cause, surveys wind inaccuracy or even cannot achieve survey wind
Function；The problem of solid state pressure wind measuring device maximum is its pressure by hole is felt in strong wind and rainfall at present, and pressure is felt
Hole can be blocked by rainwater, cause institute's measuring pressure abnormal, cause to survey wind devices failure.And the design of its pressure piping is upward one small
After section straight down, sensor circuit design is limited due to receiving by sense body diameter in bottom, it is equal by sense circuit design
It is relatively thin, it will cause water droplet and splashed to downwards by sense pipeline or when ambient humidity is larger, when temperature change is very fast by after feeling hole
Due to the condensation of water droplet, steam is caused to block in inside by sense pipeline or even condensation accumulation in downward thinner pipeline
In, it causes water droplet to block gas circuit, causes pressure measurement abnormal.
Summary of the invention
The utility model is more in order to solve widely applied Ground Meteorological wind detection sensor such as vane weather vane type rotary part,
Cannot achieve accurate measurement when freezing on sense wind component and rotating shaft assembly should not use in harsh environments.Current consolidates
State pressure wind measuring device, by sense hole in strong wind and rainfall, pressure can be blocked pressure by sense hole by rainwater, cause to survey pressure
Power is abnormal, leads to the problem of surveying wind devices failure, provides a kind of waterproof construction of solid-state wind measuring device pressure by sense pipeline.
The utility model takes following technical scheme: a kind of waterproof construction of solid-state wind measuring device pressure by sense pipeline, packet
It includes by sense body component, thermal insulation board and base assemblies, is included cylinder by sense body by sense body component, cylinder is several by being provided on sense body
Straight trough type is by hole is felt, and for straight trough type by sense hole and pressure by sense piping connection, pressure is intracavitary in Pear-Shaped retardance by the setting of sense pipeline,
Pressure by sense pipeline with cylinder is set connect by the pressure sensor at the top of sense body, cylinder is internally provided with gas circuit turn by body is felt
Block and several differential pressure pick-ups are connect, base assemblies include pedestal, and temperature is provided in pedestal by sense unit and solving unit, is felt
Thermal insulation board is provided between body component and base assemblies.
Further, Pear-Shaped retardance chamber includes that the circular cross-section that diameter is 5.5mm and the circle that diameter is 2mm are cut
Face, the circular cross-section of 5.5mm are connected with the circular cross-section of 2mm, and the closing in of two circular cross-sections is 1mm.
Further, cylinder is each provided with one group of unit heater by the top and bottom of sense body.
Compared with prior art, the utility model, will be by the sensor of sense body in the case where not influencing its aerodynamic configuration
It is placed on by the top of sense body, can be had biggish design space by sense pipeline, each by sense body diameter limited in this way
By sense channel interior devise " cucurbit " type by sense pipeline, and pressure sensor is arranged in the top of device, is felt
Partial interior is directly reached pressure sensor pressure-sensitive part by sense pipeline straight up, and avoiding can make to lower pipeline in the past
At condensed water condensation accumulation caused by pressure measurement exception situation occur.Solid-state wind speed and direction is improved to dislike at sensor
Reliability under bad environment.

Specific embodiment
As shown in Figure 1, 2, a kind of solid-state wind measuring device pressure by sense pipeline waterproof construction, including by sense body component 1, every
Hot plate 3 and base assemblies 2 are included cylinder by sense body 4 by sense body component 1, and cylinder is felt by several straight trough types are provided on sense body 4
Hole 5, straight trough type are connected by sense hole 5 and pressure by sense pipeline 11, and pressure is arranged in Pear-Shaped retardance chamber 12 by sense pipeline 11, pressure
Power by sense pipeline 11 with cylinder be set connect by the pressure sensor at sense body 4 top, cylinder is internally provided with gas circuit by body 4 is felt
Transfer block 10 and several differential pressure pick-ups, base assemblies 2 include pedestal 7, and temperature is provided in pedestal 7 by sense unit 9 and is resolved
Unit 8 is provided with thermal insulation board 3 by between sense body component 1 and base assemblies 2.Cylinder is each provided with by the top and bottom of sense body 4
One group of unit heater 6.
Each pressure is shown in attached drawing 4 by sense pipeline by the pressure that sense circuit design is " cucurbit " shape by sense hole, and will
Pressure sensor is arranged in the top of device, and all inside is directly reached pressure sensor portion by sense pipeline straight up
Point, the situation for avoiding the pressure measurement exception condensed water condensation accumulation that will cause to lower pipeline in the past caused by occurs.
Since its pressure is designed by sense hole using thin straight trough type pressure sensing hole, enter when external rainwater splashes by sense pipeline
It not will cause a large amount of water droplet and enters afterwards, and by pressure sensor top set, causes the size by sense pipeline to be increased, is
It prevents the water droplet moment splashed to be covered with entire effectively by sense hole, devises " cucurbit " type by sense pipeline.Form one
The thin-walled point side structure of 1mm wide about 70mm long is entirely felt so that splashing and entering not being covered with rapidly by the water droplet in sense pipeline
Pipeline causes water droplet to block, formed atmospheric pressure " lift " water droplet by sense pipeline in situation, cause by sense loine pressure it is different
Often.On the thin-walled on " the sharp side " that this Pear-Shaped closes up, water droplet gravity is necessarily greater than its tension, to make water droplet along its straight trough
Type thin-walled flows downward, and water droplet is squeezed out by sense hole, normally adopts pressure shape to make to be in always by the pressure among sense pipeline
State.
As shown in figure 4, Pear-Shaped retardance chamber 12 includes the circular cross-section that diameter is 5.5mm and the circle that diameter is 2mm
Section, the circular cross-section of 5.5mm are connected with the circular cross-section of 2mm, and the closing in of two circular cross-sections is 1mm.When water droplet passes through 1mm
By sense hole enter by sense pipeline when, be introduced into the circular hole of 5.5mm, and since water can be made there are the closing in of 1 millimeter of Pear-Shaped
Drop can not be run through, and the diameter for being covered with rear is the circular hole of 2mm, and 2mm circular hole is connected with 5.5mm circular hole, and water droplet is caused to exist
Within the scope of this water droplet with it is larger by sense pipe contact perimeter, water droplet can not individually block adjacent two circular holes, always along 1mm
Sharp side slot slide, thus realize waterproof block purpose.
