Abstract

The mine intrinsically safe pressure detector of the present invention includes a main housing, a back cover, a mine pressure sensor, a circuit board and a support frame. The support frame is fixedly installed on the back cover, and the circuit board is installed on the support frame. On the top, the support frame includes a support plate. The upper end of the support plate is provided with a fixed column. The fixed column is provided with a through hole for easy combination with the circuit board. The front panel of the main housing is provided with a rectangular window, a circular window, and a circular window. Through holes and rivet holes, the window gland is tightly attached to the front panel through rivets, and the mining pressure sensor is fixed on the lower panel through a butterfly nut; the mining intrinsically safe pressure detector of the present invention is small in size , easy to operate, long service life; when in use, the pressure sensor is connected to the liquid of the device under test through a quick connector, and the change in the resistance signal is caused by the change in liquid pressure. After being amplified and driven, it can be displayed in the window glass. The display is intuitive, easy to use, and has strong adaptability to the environment.

Description

technical field [0001] The invention relates to a mine safety detection device, in particular to a mine intrinsically safe pressure detector. Background technique [0002] Mine intrinsically safe pressure detector is an automatic monitoring equipment integrating microcomputer technology and computer technology for automatic observation and display of hydraulic prop pressure; it is mainly used for automatic measurement and display of hydraulic prop pressure of fully mechanized mining supports in coal mines. The existing pressure detector has poor moisture and dust resistance, complex structure and poor environmental adaptability. With the speed of product output changes, environmental changes and other factors, the working environment of the detector components is also changing every day, and most of the electronic components in the detector are precision components, which require a relatively stable working environment; how to provide a use It is very important to have a mi...
