Description
Technical field
The utility model relates to a kind of field of mining equipment, are related to a kind of survey wind devices, and in particular to a kind of to survey with underground
The operating stick that wind mechanical wind table is used cooperatively.
Background technique
Since there is air viscosity and roadway wall surface to have certain roughness, so that air can be generated in flowing in roadway
Inside and outside frictional force, it is uniform for resulting in distribution of the wind speed on drift section not being.Wind speed wind speed at the wall periphery of lane is minimum,
From lane wall to tunnel axis direction, wind speed is gradually increased.Wind speed is maximum usually near the axle center of tunnel.In underground because of roadway section
With the difference of support form, for maximum wind velocity often not on the axle center of tunnel, wind speed profile is also asymmetric.In measurement tunnel average wind
When fast, if airspeedometer (wind table) is rested near the side wall of tunnel, measurement result will be less than normal compared with actual value；Airspeedometer is located at lane
When making measurement result bigger than normal again when road shaft core position, therefore measuring tunnel mean wind speed, airspeedometer cannot be made to be parked in a certain fixation
Point, and should equably be measured on the cross section of tunnel according to a fixed line, data just can truly reflect out the flat of tunnel
Equal wind speed.
In order to measure tunnel mean wind speed, route method can be used when surveying wind and (uniformly move wind table by certain route
It is dynamic)；Or it is surveyed using lattice fix point method (drift section being divided into several lattice, wind table stops the equal time in every lattice)
It is fixed, calculating mean wind speed is then sought, common wind table mobile route has normal formula, six wire types, four-wire type, lattice fixed point etc..It surveys
Using method of leaning to one side when wind person surveys wind with wind table in tunnel, the method for leaning to one side is to survey wind person to stand backwards to wall, holds wind table for hand
Arm is stretched to distinguished and admirable vertical direction, is then made in drift section uniformly mobile.Due to survey wind person stand in tunnel reduce it is logical
Wind section, to increase wind speed, measurement result will be bigger than normal compared with actual wind speed.
For the anemometer mast used now primarily to solution head-room is larger, survey wind person, which lifts wind table survey wind, certain difficulty
The problem of spending, there is also many defects when in use at present is especially taking first is that this straight-bar is very inconvenient when carrying
When the tools such as monkey car, people's vehicle, carry constant just as very distinct issues；Second is that this anemometer mast is in horizontal and vertical movement
When do not ensure that wind table impeller is vertical with wind direction, make measurement there are large errors；Third is that this unyielding survey wind
When in use, surveying wind person must be with wind table all on the same cross section in tunnel, and it is logical that this greatly reduces the reality in tunnel for bar
Wind area causes measured data bigger than normal serious.
Therefore, make it is a kind of it is easy to carry, measurement is accurate, the convenient and fast anemometer mast of operation, become and improve underground ventilating work
The effective way of data accuracy becomes technical problem urgently to be resolved.
Utility model content
In order to overcome above-mentioned shortcoming, utility model aims to solve mine uses when carrying out anemometry
The problems of wind table, and overcome the problems, such as that existing anemometer mast exists, develop a kind of convenient to use, the accurate auxiliary behaviour of measurement
Make bar.
The technical solution of the utility model are as follows: a kind of that the operating stick that wind mechanical wind table is used cooperatively, the operation are surveyed with underground
Bar is mainly made of handle (1), telescopic rod (2), support rod (5), concave cross bar (6), clip (7) etc., cylindrical handle (1)
Upper to be provided with non-slip rubber block, the telescopic rod (2) being connected with handle (1) is made of the telescopic joint of several reduced diameters,
There is the groove (3) that can increase friction on telescopic rod (2), two support rod (5) one end are connected through a screw thread head (4) and fix, spiral shell
Line connector (4) is threadedly engaged use with telescopic rod (2) top hollow space, and the other side of two support rods (5) leads to respectively
It crosses limiting slot (10) and retraction slot (11) is fixed concave cross bar (6), be fixed with clip (7) among cylindrical concave cross bar (6)
Semi-circular structure, both ends have one section of lesser linkage section of diameter (9) for and the limiting slot (10) and retraction slot on support rod (5)
(11) it is used cooperatively, concave cross bar (6) be freely rotated can, be also respectively provided with limited block (8) in linkage section (9) two sides.
Further, the limiting slot (10) is located at support rod (5) end, is circular hollow structure, retraction slot (11) and limit
Position slot (10) opening position is connected, and is manufactured using elastic rubber.
Further, the radius d and limiting slot (10) radius D and retraction slot (11) spacing 2r of the linkage section (9) meet: D >
d>r。
Further, the clip (7) passes through semicircular structure bottom that is hinged or being weldingly fixed among concave cross bar (6)
Portion.
The beneficial effects of the utility model are that one kind that above-mentioned technical proposal proposes surveys the cooperation of wind mechanical wind table with underground
The operating stick used is the new design obtained on the basis of the mine prior art is sufficiently investigated and used, structure letter
Single rationally the rod piece main body of contraction is easy to carry, and concave cross bar (6) is under self weight and wind table gravity, around linkage section (9)
It is rotated freely on support rod (5), it is ensured that Mechanical wind meter and survey air way road face keeping parallelism, measurement result is accurate, and operation is just
Victory, can effectively overcome presently, there are problems, be suitble to mine popularity use.
