Description

Technical Field

[0001] The utility model belongs to intelligent coal mine automation control equipment, in particular to a mining intrinsically safe angle sensor housing. Background Art

[0002] Angle sensors are mainly used to test the position of the workpiece angle, which facilitates the control equipment to collect angle signals, such as the opening angle of the damper or wind window. There are two output methods of angle sensors used in coal mines on the market, one is 485 communication output, and the other is analog output. However, both methods send the angle signal to the control host or PLC controller. The angle sensor itself does not display the angle data it detects. The staff who install the angle sensor cannot directly observe the angle information displayed by the angle sensor. After the equipment is installed on the damper or wind window, if there is an error in the installation angle, the angle sensor needs to be removed and then reinstalled on the damper or wind window, making the debugging of the angle sensor extremely inconvenient and increasing the workload of the workers. At the same time, since the angle shaft potentiometer of the angle sensor is set on the outside of the angle sensor box to facilitate the connection of the angle sensor to the damper or wind window, and the environment in the coal mine is relatively harsh, it is very easy for the staff to damage the angle shaft potentiometer when carrying the angle sensor, which makes the angle sensor unusable.
