Description
Technical field
The utility model belongs to the mining equipment technical field, relates to a kind of sensor, especially a kind of mining differential pressure pick-up
Background technology
China is big coal country, output of coal leaps to world front three, because most of coal all is stored in the underground, so must exploit with the form of mine, and underground work is breakneck for coal workman's personal safety, a lot of coal mining accidents all can occur every year in China, and all can pay each time the cost of blood.Therefore, the Environmental Monitoring under the mine just becomes particularly important.Circumstance complication under the mine, down-hole pressure also often change, and therefore, the monitor well downforce that needs a kind of reliable equipment to implement changes, and is convenient to the early detection Coal Mine Disasters, trouble-saving generation.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of mining differential pressure pick-up is provided, this sensor can show the differential pressure value of measured point in real time, the output of band digital interface can be used with domestic other mine supervision system, Digital Mine system and life saving system are compatible.
The purpose of this utility model solves by the following technical programs:
This mining differential pressure pick-up comprises housing, is provided with circuit board, pressure sensor, buzzer, aviation plug and alarm lamp in the described housing; Described circuit board is provided with power circuit and oscillating circuit; Wherein pressure sensor, buzzer and aviation plug are connected by circuit and are connected with circuit board; Described buzzer is installed in the front panel below of housing, and front panel is provided with perforate in the position that buzzer is installed; Described alarm lamp is installed in the housing upper end; Described aviation plug is installed in the side of housing; The lower end of described housing is provided with two valves, and described valve is connected to pressure sensor by pipeline.
Be provided with sealing mat between the front panel tapping of above-mentioned housing and the buzzer.
Above-mentioned housing is that a upper end is with the box-like shell of handle.
Above-mentioned housing upper end is provided with link, and described handle is connected to the housing upper end by link.
Above-mentioned housing rear end is sealed by bonnet, is provided with rear sealing cushion for cover on the bonnet.
The differential pressure on the ground such as mining differential pressure pick-up of the present utility model can be airtight to mine fan, air door, airway continues monitoring.It can show the differential pressure value of measured point in real time, and the output of band digital interface can be used with domestic other mine supervision system, Digital Mine system and life saving system are compatible.Sensor is mining intrinsic safety type, and reliable operation is simple in structure, flexible and convenient to use.Be convenient to the early detection Coal Mine Disasters, trouble-saving generation.
