Problems solved by technology

Since it can only measure the instantaneous wind speed, and the dust and air humidity in the wind measurement environment also have a certain influence on it
Therefore, this kind of wind meter can only be used under the condition of humidity ≤ 85%, while the humidity in coal mines often exceeds 85%, and can even reach 100%.

Embodiment Construction

[0017] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 figure 2 As shown, the coal mine roadway micro-wind speed measuring device of the present invention mainly consists of a top bracket 1, a traction rope 2, a lightweight ball 3, an arc scale 4 and a handle 5; the lightweight ball 3 is made of polyester fiber material Made, the diameter of the sphere is 0.1m; the scale value on the arc scale 4 is calibrated on the basis of theoretical formula calculation and experimental wind speed correction, the range is 0m / s~0.5m / s, and the measurement accuracy can be Reach 0.05m / s. One end of described arc scale 4 is connected with an end of top bracket 1, and the other end of arc scale 4 is connected with the handle 5 that is convenient for the operator to hold, and the radius of curvature of arc scale 4 and the length of top bracket 1 Equal, guide groove 6 is left in the middle of described a...

Abstract

The invention discloses a gentle wind speed measurement device and method for a coal mine tunnel, and the device mainly consists of an arc-shaped graduated scale, a light large-section ball, and a hauling rope. One end of the hauling rope is fixed at a top supporting point, and the other end of the hauling rope is used for hauling the light large-section ball. The light large-section ball can swing upwards through a certain angle under the action of gentle wind in the coal mine tunnel. The higher the wind speed is, the larger the swinging angle is. The arc-shaped graduated scale is used for measuring the swinging angle, and a corresponding wind size is marked on the graduated scale. The device is simple in structure, is low in cost, is portable, can measure the speed of gentle wind effectively and quickly, and facilitates the adjustment and management of a wind network of a coal mine.

Description

technical field [0001] The invention relates to a device and method for measuring micro wind speed, in particular to a device and method for measuring micro wind speed in coal mine roadways which play an important role in coal mine safety management. Background technique [0002] Coal mine ventilation system is a complete system consisting of ventilation network, ventilation power and ventilation control facilities. Its main purpose is to provide sufficient fresh air to the working area of ​​the coal mine and discharge dirty air in time. The complete flow route of the air flow in the ventilation system is very important to the safe production of coal mines. The air flow enters the mine from the air inlet shaft, passes through the underground operating sites, and then enters the return air shaft, and finally exits the mine from the return air shaft. During the production period, the ventilation system is mainly to drive the ventilation power in the most economical way, to pro...
