Further clear, complete explanation is made in invention.It should be noted that in the case where not conflicting, embodiment in the application and
Feature in embodiment can be mutually combined.
In a kind of typical implementation method, a kind of underground coal mine multiple spot wind measuring device that the present invention is provided, such as Fig. 1 institutes
Show, including airspeedometer 1, also including connecting seat 2 and linked network.With reference to Fig. 4 and Fig. 5, described connecting seat includes the cross section at top
For semicircle, longitudinal section is trapezoidal class taper stage body 201, the bottom of class taper stage body 201 is one section of semicylinder 202, semicircle
It is the class bullet 205 of semicircle that the bottom of cylinder 202 connects one section of cross section, and the bottom of class bullet 205 is counterweight, 203, connecting seat
2 preceding surfaces are vertically and fixedly provided with connecting pole 204, and the front end face of connecting pole 204 is connected with the back side of airspeedometer 1；Described linked network includes
Linked network framework 3 and the more than two gusset plates 4 set according to tunnel Ce Feng positions, connect the horizontal He of rope 5 on linked network framework 3
Longitudinal rope 6, gusset plate 4 is fixed at described horizontal rope 5 and the intersecting node of longitudinal rope 6, and the surface of gusset plate 4 is fixed
There is fixed seat 7, the cross section including top in the cavity 701 being adapted to the connecting seat 2, the cavity is provided with inside fixed seat 7
For semicircle, longitudinal section is trapezoidal class taper stage body, class taper stage body bottom is one section of semicylinder, and semicylinder bottom connects
The class bullet that one section of cross section is semicircle is connect, the space for accommodating balancing weight 203, the front bulkhead of fixed seat 7 are arranged at class bullet bottom
It is provided with and the insertion of cavity 701 and the groove 702 that makes connecting pole 204 insert and slide up and down.
In embodiment of above, when using, first airspeedometer 1 is fixed with connecting seat 1, using expansion link or its other party
Connecting seat is placed in the inner chamber of fixed seat 7 by formula.The cavity top structure of fixed seat 7 is one section of cross section for semicircle with connecting seat top
Shape, longitudinal section are trapezoidal class taper stage body, because such taper stage body open top is larger so that even if distant
In the case of, connecting seat 2 is also easily placed in fixed seat 7.Semicylinder in the middle part of the cavity of fixed seat 7 middle part and connecting seat rises
Fixation, prevents airspeedometer 1 from waving.The one side of balancing weight 203 of the bottom of connecting seat 2 has the effect for stablizing airspeedometer 1, separately
On the one hand help to overcome the frictional force between fixed seat 7 and connecting seat 2 so that the connection between them is easier.Connecting seat 2
In the connection procedure of fixed seat 7, connecting pole 204 is along the groove of fixed seat 7 to downslide until the cavity of fixed seat 7 top and connecting seat 2
Top is close to, and connecting pole 204 also has the effect for preventing airspeedometer 1 from swinging.After connection, airspeedometer 1 is in the outside of fixed seat 7
Start working windward.
In a preferred embodiment, described linked network framework 3 is fixedly connected by steel wire rope 8 with tunnel side wall 9.
In a kind of more specific embodiment, fixed seat 7 is put into present invention additionally comprises by the lifting of the connecting seat 2
Expansion link, the expansion link includes integral the first bar portion 10 and the second bar portion 11 of suit, and the diameter of the first bar portion 10 is less than the
Two bar portions 11, the top of the first bar portion 10 is provided with hook 12, and the top of connecting seat 2 is provided with the link used cooperatively with the hook 12
206.For survey wind position higher, airspeedometer and connecting seat are lifted to the fixed seat 7 of destined node by above-mentioned expansion link
It is interior.
In a preferred embodiment, mark has corresponding position coordinates 13 on the gusset plate 4.In same lane
In the case that road section repeatedly surveys wind, it is possible to use same linked network, so there is no need to adjustment node location every time, according to having marked
The position coordinates remembered accordingly places installation airspeedometer 1.
In a preferred embodiment, the built-in automatic voice number reporting module of described airspeedometer, operating personnel according to
Count off record surveys wind data every time, can peripheral earphone, voice counting interval time can arbitrarily set.Moreover it is preferred that select

Equal wind speed and air quantity.Using novel wind-speed sensor and high-performance microprocessor, range ability is 0 ~ 25m/s, meets low middle height
Wind speed is measured, and is saved for the work for measuring the wind speed suitable range airspeedometer of selection.Automatic identification simultaneously rejects invalid measurement data
（Relative error is more than 5%）And measured value is corrected, directly display measured value.Circuitry uses modularized design.Deposit
Storage element circumscribed USB interface, conveniently calls.Keyboard is touched using diaphragm type is totally-enclosed, is adapted to be used in the adverse circumstances of underground.
Expansion link interface is provided with, for larger basal area tunnel, wind off-balancesheet can be connect and be fixed on expansion link, hand-held expansion link movement is surveyed
Wind.Power supply uses rechargeable battery, is shown with low-voltage and automatic shut-off function, and continuous 3min is without operation automatic shutdown, tool
There is power-down data protection function, it is possible to decrease instrument power consumption, reduce charging times, extend battery life.LED digital displays part, belongs to
Emergency lighting, electronic circuitry part belongs to safety spark, and rechargeable battery meets the requirements.The explosion-proof type of airspeedometer belongs to mine intrinsic safety
Type, it is adaptable to the inflammable and explosive environment of underground coal mine.
Application method of the invention is described further below in conjunction with the four-wire method wind detection method in circuit method.
First, linked network is fixed on tunnel side wall, according to pre- location survey wind position adjustment node, the present embodiment sets 12 sections
Point.The power supply of airspeedometer 1 is opened, voice automatic number-sounding interval time is set（Such as interval time 5s, time of measuring be 60s or
Interval time 10s, time of measuring is 120s）, by input through keyboard drift section parameter.Then with by connecting seat 7 and airspeedometer 1
It is placed into the fixed seat of node, impeller end face is met to distinguished and admirable and vertical with wind direction, is pressed after wheel rotation is normal
" beginning " key starts to survey wind.According to airspeedometer automatic voice number reporting, successively from 1. → 2. → 3. →...→ smoothly remove
With holding movable airspeedometer, higher position expansion link, as shown in route map, when airspeedometer voice counting " 12 ", by " stopping
Only " bond Shu Benci measurements, airspeedometer records measurement result automatically.To ensure the accuracy of measurement, same section surveys wind number of times
No less than 3 times, 3 times measurement result relative error is no more than 5%, takes its average value as measurement result（VTable speed）.If measurement phase
5% is more than to error, illustrates that survey wind result is undesirable, airspeedometer automatic identification simultaneously rejects the measurement data, need to add once
Wind is surveyed, until qualified；Finally, " reading wind " key is pressed, airspeedometer is calculated and corrected automatically, so as to obtain tunnel mean wind speed（VLane is equal）,
Then air quantity is calculated.This measuring point is surveyed wind and is terminated.
The scope of protection of present invention is not limited to above specific embodiment, to those skilled in the art, the present invention
Can there are various deformation and change, all any modification, improvement and equivalents made within design of the invention with principle
Should all be included within protection scope of the present invention.
