CN201258760Y - Smoke sensor - Google Patents

Abstract

The utility model discloses a smoke sensor. A mine monitoring substation is arranged outside a mine well; the input end of the mine monitoring substation is connected with the smoke sensor through a signal line, a positive power line and a negative power line; the smoke sensor is arranged on the position 10 to 15 m away from the side of the lower air outlet of the conveyer roller in the mine well; and a signal lamp and a light and sound alarm device are arranged in the smoke sensor. The utility model can predict whether the smoke concentration in the mine roadway exceeds the standards or not; so that the personnel on the well can promptly and accurately know about the environmental conditions of the underground roadway and then take corresponding measures to ensure the safety of normal production.

Description

The Smoke Sensor device

Technical field

The utility model relates to the smog safety monitoring device under a kind of coal mine, particularly a kind of Smoke Sensor 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, whether the tunnel of down-hole is produced smog monitor timely, to prevent serious disaster accidents such as breaking out of fire or gas explosion.The problem that exists is at present: can't prevent in advance fire under the coal mine or gas explosion situation, often cause serious disaster accident.

Summary of the invention

The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of device that can detect smog timely and accurately 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 connects Smoke Sensor with holding wire, positive-negative power line, and this Smoke Sensor is installed in the 10-15m place on the converyor roller leeward oral-lateral limit in the mine; This Smoke Sensor built-in signal lamp and acoustic-optic alarm.

The beneficial effects of the utility model are: predict in advance whether smokescope exceeds standard in the mine laneway, aboveground personnel can grasp the ambient conditions of underworkings timely and accurately, take appropriate measures to guarantee the safety of 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. Smoke Sensor; 4. positive-negative power line.

The specific embodiment

As shown in Figure 1, mining outstation 1 is arranged on outside the mine, and mining Smoke Sensor 3 adopts quad line and mining outstation 1 related use.The input of mining outstation 1 connects Smoke Sensor 3 with holding wire 2, positive-negative power line 4.The output voltage of mining outstation 1 is Smoke Sensor 3 power supplies, and Smoke Sensor 3 is transferred to mining outstation 1 to detected information by holding wire 2.This Smoke Sensor 3 is installed in the 10-15m place on the converyor roller leeward oral-lateral limit in the mine; Perhaps be installed in the place that easy breaking out of fire such as coal-face and explosives magazine and gas are built up.At Smoke Sensor 3 built-in signal lamp and acoustic-optic alarms.

Claims (1)

1, a kind of Smoke Sensor device, mining outstation (1) is set outside mine, it is characterized in that: the input of mining outstation (1) connects Smoke Sensor (3) with holding wire (2), positive-negative power line (4), and this Smoke Sensor (3) is installed in the 10-15m place, converyor roller leeward oral-lateral limit in the mine; This Smoke Sensor (3) built-in signal lamp and acoustic-optic alarm.
