Specific embodiment
In order to make those skilled in the art better understand the present invention, below in conjunction with reference attached drawing and in conjunction with the embodiments to this
Further clear, complete explanation is made in invention.It should be noted that in the absence of conflict, embodiment in the application and
Feature in embodiment can be combined with each other.
In a kind of typical embodiment, a kind of underground coal mine multiple spot wind measuring device provided by the invention, such as Fig. 1 institute
Show, including airspeedometer 1, further includes attachment base 2 and linked network.With reference to Fig. 4 and Fig. 5, the attachment base includes the cross section at top
It is trapezoidal class taper stage body 201 for semicircle, longitudinal section, 201 bottom of class taper stage body is one section of semicylinder 202, semicircle
202 bottom of cylinder connects the class bullet 205 that one section of cross section is semicircle, and 205 bottom of class bullet is counterweight, and 203, attachment base
2 front surfaces are vertically and fixedly provided with connecting column 204, and the front end face of connecting column 204 is connect with 1 back side of airspeedometer；The linked network includes
Linked network frame 3 and the more than two gusset plates 4 being arranged according to the tunnel position Ce Feng connect 5 He of lateral rope on linked network frame 3
Longitudinal rope 6, gusset plate 4 are fixed at the node that the lateral rope 5 and longitudinal rope 6 intersect, and 4 surface of gusset plate is fixed
There is fixing seat 7, the cavity 701 being adapted to the attachment base 2 is provided with inside fixing seat 7, includes the cross section at top in the cavity
It is trapezoidal class taper stage body for semicircle, longitudinal section, 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 clump weight 203,7 front bulkhead of fixing seat are arranged at class bullet bottom
It is provided with the slot 702 for penetrating through with cavity 701 and being inserted into connecting column 204 and sliding up and down.
In embodiment of above, in use, it is first that airspeedometer 1 and attachment base 1 is fixed, using telescopic rod or its other party
Attachment base is placed in 7 inner cavity of fixing seat by formula.It is semicircle that 7 cavity top structure of fixing seat and attachment base top, which are one section of cross section,
Shape, longitudinal section are trapezoidal class taper stage body, since such taper stage body top opening is larger, so that even if apart from farther away
In the case of, attachment base 2 is also easy to be placed in fixing seat 7.Semicylinder in the middle part of 7 cavity of fixing seat and in the middle part of attachment base rises
Fixed function prevents airspeedometer 1 from waving.203 one side of clump weight of 2 bottom of attachment base has the function of stablizing airspeedometer 1, separately
On the one hand help to overcome the frictional force between fixing seat 7 and attachment base 2, so that the connection between them is easier.Attachment base 2
In 7 connection procedure of fixing seat, connecting column 204 along fixing seat 7 slot to glide until 7 cavity of fixing seat at the top of with attachment base 2
Top is close to, and connecting column 204 also has the function of preventing airspeedometer 1 from swinging.After connection, airspeedometer 1 is in 7 outside of fixing seat
It starts to work windward.
In a preferred embodiment, the linked network frame 3 is fixedly connected by wirerope 8 with tunnel side wall 9.
In a kind of more specific embodiment, the invention also includes the attachment base 2 lifting is put into fixing seat 7
Telescopic rod, the telescopic rod include integral the first bar portion 10 and the second bar portion 11 of suit, and 10 diameter of the first bar portion is less than the
Two bar portions 11 are equipped with hook 12 at the top of first bar portion 10, the links being used cooperatively with the hook 12 are equipped at the top of attachment base 2
206.For higher survey wind position, airspeedometer and attachment base are lifted to the fixing seat 7 of destined node by above-mentioned telescopic rod
It is interior.
In a preferred embodiment, label has corresponding position coordinates 13 on the gusset plate 4.In same lane
In the case that road section repeatedly surveys wind, same linked network can be used, so there is no need to adjust node location every time, according to having marked
The position coordinates remembered accordingly place installation airspeedometer 1.
In a preferred embodiment, automatic voice number reporting module built in the airspeedometer, operator 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
Airspeedometer can with the following functions and structure, roadway and barrier basal area can be set, it is flat to can measure tunnel instantaneous wind speed, tunnel
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 measures, and saves the work that suitable range airspeedometer is selected for measurement wind speed.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.It deposits
Element circumscribed USB interface is stored up, calling is facilitated.Keyboard is touched using diaphragm type is totally-enclosed, is suitble to use in the adverse circumstances of underground.
Wind off-balancesheet can be connect and is fixed on telescopic rod by larger basal area tunnel equipped with telescopic rod interface, hold the mobile survey of telescopic rod
Wind.Power supply uses rechargeable battery, shows with low-voltage and automatic shut-off function, continuous 3min have without operation automatic shutdown
Have power-down data protection function, can lowering apparatus power consumption, reduce charging times, extend battery life.LED digital display part, belongs to
Emergency lighting, electronic circuitry part belong to safety spark, and rechargeable battery meets the requirements.The explosion-proof type category mine intrinsic safety of airspeedometer
Type is suitable for 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 route method.
Firstly, linked network is fixed on tunnel side wall, node is adjusted according to predetermined survey wind position, 12 sections are arranged in the present embodiment
Point.1 power supply of airspeedometer 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 120s）, drift section parameter is inputted by keyboard.Then with by attachment base 7 and airspeedometer 1
It is placed into the fixing 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, → 2. → 3. →...→ smoothly removed successively from 1.
With holding movable airspeedometer, higher position telescopic rod, when airspeedometer voice counting " 12 ", is pressed and " is stopped as shown in route map
Only " bond Shu Benci measurement, airspeedometer automatically record measurement result.For the accuracy for guaranteeing measurement, same section surveys wind number
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 measuring phase
5% is greater than to error, illustrates that survey wind result is undesirable, airspeedometer automatic identification simultaneously rejects the measurement data, need to add primary
Wind is surveyed, until qualification；Finally, pressing " reading wind " key, airspeedometer is calculated and is corrected automatically, to obtain tunnel mean wind speed（VLane is equal）,
Then air quantity is calculated.This measuring point, which surveys wind, to be terminated.
The scope of protection of present invention is not limited to the above specific embodiment, to those skilled in the art, this
Invention can there are many deformation and change, it is all design of the invention within principle it is made it is any modification, improve and be equal
Replacement should be all included within protection scope of the present invention.
