Abstract
The utility model discloses a mining wind speed sensor. A mine monitoring substation is arranged outside a mine well; the input end of the mine monitoring substation is connected with the wind speed sensor through a signal line and two power lines; the wind speed sensor is arranged in a position 30 cm away from the top of the mine roadway in the vertical direction; and a light and sound alarm device and a signal lamp are arranged in the wind speed sensor. The utility model can continuously detect the wind speed and wind volume of the mine roadway, so that the personnel on the well can promptly and accurately know about the ventilation conditions of the underground roadway, thereby ensuring the safety of the daily normal production.
Description
Technical field
The utility model relates to a kind of safety monitoring device of colliery underground survey dash situation, is specifically related to a kind of air velocity transducer device.
Background technology
Continuous expansion and extension along with mine underground mining scope, subsurface environment also becomes and becomes increasingly complex, under the most important major premise of personnel's life security, to carry out ventilation to the air of down-hole, to guarantee the pure and fresh of underground air, satisfy the accumulation of personnel's eupnea and minimizing pernicious gas.At present the problem that occurs is: because ventilation situation under the coal mine is not understood, pernicious gases such as gas and carbon monoxide are built up situation can not in time learn, cause the personnel in the pit to suffocate easily and cause mine disaster.
Summary of the invention
The purpose of this utility model is for solving the deficiency that prior art exists, a kind of wind speed sensor for coal mine device that can measure dash size under the coal mine being provided.
The technical scheme that its technical problem that solves the utility model adopts is: mining outstation is set outside mine, the input of mining outstation is connected air velocity transducer by a holding wire with two power lines, this air velocity transducer is installed in perpendicular to 30cm position, mine laneway top, and acoustic-optic alarm and signal lamp are set in this air velocity transducer.
The beneficial effects of the utility model are: by mine laneway wind speed air quantity of living in is carried out continuous detecting, the ventilation situation of the grasp underworkings that aboveground personnel can be has promptly and accurately guaranteed the safety of daily ordinary production.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structure connection diagram of the present utility model.
Among the figure: 1. mining outstation; 2. holding wire; 3. air velocity transducer; 4. power line.
The specific embodiment
As shown in Figure 1, mining outstation 1 is arranged on outside mine, and the input of mining outstation 1 adopts the three-core cable line to connect air velocity transducer 3, and wherein three heart yearns are respectively a holding wire 2 and two power lines 4, and power line 4 is positive and negative power line.Air velocity transducer 3 should be arranged on before and after the tunnel no branch in the 10m distinguished and admirable, do not have turn round, accessible, section no change, can accurate calculation of wind speed the place.The utility model is installed in air velocity transducer 3 perpendicular to 30cm position, mine laneway top, the air measuring station setting of exploiting field return airway, a wing return airway, main return airway.In this air velocity transducer 3, acoustic-optic alarm and signal lamp are set, when wind speed is lower than or surpass setting value, can send sound, visual alarm.
Wind speed sensor for coal mine 3 is a kind of intelligence instruments that adopt embedded scm control, adopt the ultrasonic wave principle, adopts the intrinsically safe circuit design.The utility model is applicable in the tunnel that has gas explosion danger under the coal mine, can carry out continuous detecting to tunnel of living in wind speed air quantity.
