Background technology

There to be enough air quantity to dilute gas under the mine in order ensureing,, need to measure the wind speed in the mine at any time to ensure miner's life security.At present, the wind speed that often adopts the colliery to come continuous monitoring mine ventilation main return airway, the main air measuring station in down-hole and ventilating fan etc. to locate with the wind speed sensor, the colliery is the important instrument that the mine ventilation security parameter is measured with the wind speed sensor.The colliery with the wind speed sensor mainly by housing, be installed in the display screen on this housing and be positioned at housing below and form through the wind apparatus that is subjected to that connecting link links to each other with this housing, in the described housing sensor circuit board is installed, the described wind apparatus that is subjected to is made up of wind guiding member and wind velocity signal generator two parts of being installed in this wind guiding member, wind guiding member is made up of front and back side plate and the upper plate and the lower plate that are installed in this front and back side plate upper and lower side respectively, and the lead of described wind velocity signal generator through passing described connecting link links to each other with described sensor circuit board.Convert wind speed to electric signal by the wind velocity signal generator, be transferred to sensor circuit board then and handle, be presented at after the processing on the display screen, have the advantage of demonstration wind speed directly perceived, but, because the colliery is to be placed in the mine with the wind speed sensor, so or need the Security Officer to check at any time, yet, send the appointees monitoring not only bothersome, and poor accuracy, when wind speed does not reach standard, early warning in time; With wind speed sensor and the supporting use of other safety monitoring systems, come monitor wind speed by other safety monitoring systems, this cost is too high again.

The utility model content

The purpose of this utility model is to provide a kind of air velocity transducer that has sound and light alarm, when the wind speed in the mine does not reach safety standard, can send the sound and light alarm signal intuitively.

For achieving the above object, the utility model is improved on the wind speed sensor in original colliery, by increasing sound light alarming circuit and corresponding apparatus, make air velocity transducer except measuring wind speed, when the wind speed in the mine does not reach safety standard, all right intelligent sound and light alarm, concrete technical scheme is as follows: a kind of air velocity transducer that has sound and light alarm, comprise housing, be installed in the display screen on this housing and be positioned at housing below and be subjected to wind apparatus through what connecting link linked to each other with this housing, in the described housing sensor circuit board is installed, the described wind apparatus that is subjected to is made up of wind guiding member and wind velocity signal generator two parts of being installed in this wind guiding member, wind guiding member is by preceding, back side panel and be installed in this respectively before, the upper plate of back side panel upper and lower side and lower plate are formed, the lead of described wind velocity signal generator through passing described connecting link links to each other with described sensor circuit board, Transparent lamp shade and the plate that is arranged in this Transparent lamp shade below, this lampshade are installed between described biside plate and the upper plate, in plate and described upper plate through screw retention on described side plate; LED on warning circuit plate and this warning circuit plate is installed in the described lampshade, and this warning circuit plate links to each other with described sensor circuit board; The hummer that links to each other with described warning circuit plate is installed on the front surface of described housing.

As preference, the framework that above-mentioned lampshade is made by red plastic, the light that is appeared by lampshade is ruddiness like this, ruddiness has eye-catching effect, can increase the effect of warning.Be provided with the installation journal stirrup around this framework, this installation journal stirrup is provided with circular hole, and the inner of installation journal stirrup is provided with step; The long limit inwall of described framework is provided with the pillar that extends in framework, the inner of this pillar is provided with step, by the interior rank that journal stirrup and pillar are installed the warning circuit plate is installed in the lampshade.

As another preference, the inwall of above-mentioned lampshade is a dentation, and this dentation inwall can produce refraction action to the light that LED produces, and increases light intensity.

In order to keep the structure of original air velocity transducer as far as possible, to reduce the cost of die sinking again, the utility model is by increasing lampshade between the middle plate of original casing and upper plate, circuit board is positioned in the lampshade by step in the lampshade, clamp by original screw retention, the circuit board line inserts in the housing by connecting link, and is easy for installation; And lampshade is outwards not outstanding, thereby is not vulnerable to impact, and is difficult for broken.

Beneficial effect: the utility model increases sound light alarming circuit and hummer and LED by using in original colliery on the wind speed sensor, when the wind speed in the mine does not reach safety standard, can send the acousto-optic intelligent alarm intuitively, thus the generation of prevention mine disaster; And the utility model is simple in structure, and improvement cost is low.

Further the utility model is illustrated below in conjunction with drawings and Examples:
