Abstract
The invention discloses a mining intrinsic safety type double-shaft tilt sensor comprising a sensor shell with the lower part provided with a groove. A sensor cover plate is arranged on the groove in a sealing manner; a main control PCB (Printed Circuit board) and an interface PCB are arranged in the groove, one end of the interface PCB is electrically connected with the main control PCB, and the other end of the interface PCB is electrically connected with a plug connector arranged on the sensor shell. The mining intrinsic safety type double-shaft tilt sensor has the advantages of being simple in structure, obvious in sealing effect, rapid and convenient to install, and suitable for the underground severe production operation environment and simultaneously resisting impact. A sealing pad is arranged on a combining platform surface between the sensor shell and the sensor cover plate, a pouring sealant is filled at the combining part of the sensor shell and the plug connector, thus ensuring the sealing moistureproof effect between the sensor shell and the plug connector; and a positioning pin shaft between the sensor shell and the plug connector can prevent the rotation of the plug connector and ensure the forward and backward limitation.
Description
Technical field
The present invention relates to the attitude measurement technical field, especially relate to a kind of mine intrinsic safety type double-shaft tilt angle sensor that in the abominable operating environment in down-hole, uses.
Background technology
Object inclination angle at the volley is an important parameter of describing object moving state, characteristic, in traffic, space flight, military field, all has great significance, and important effect is played in location, the tracking of target.All need measure in present many practical applications, and these measured values are used for monitoring or control to system the inclination angle.
When equipment such as coalcutter, development machine, hydraulic support during at coal mine operation; Obliquity sensor can be used for measuring fuselage operation angle, rocking arm pivot angle and the cutting head elevation angle etc. of coalcutter; Can also measure hydraulic support back timber, caving shield and workplace inclination angle etc., the status data of necessity is provided for the automatic operation control of these equipment.The colliery subsurface environment is abominable, and moisture is big, and dust is big, and highly corrosive is arranged.Electric equipment that in this kind environment, uses and accessory need have good airproof performance, and shock proof performance also need make things convenient for installation, maintenance and replacing simultaneously.
Summary of the invention
The object of the invention be to provide a kind of easy for installation, sealing property is good, have the mine intrinsic safety type double-shaft tilt angle sensor of better moisture effect.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Mine intrinsic safety type double-shaft tilt angle sensor of the present invention comprises that the bottom offers reeded sensor housing, said on said groove sealing be provided with the sensor cover plate; In groove, be provided with master control pcb board and interface pcb board, said interface pcb board one end is electrically connected with said master control pcb board, and the other end is electrically connected with plug connector on being arranged on sensor housing.
Between said sensor housing and sensor cover plate, be provided with sealing gasket, in the cavity of said plug connector afterbody and sensor housing junction, be filled with casting glue, offer pin-and-hole to plug connector outer wall direction, be provided with alignment pin in it at sensor housing.
Respectively to offering tapped blind hole, offer fixed via respectively at said sensor housing two ends in the sensor housing both sides; Said master control pcb board is connected with sensor housing through the screw in the copper insulated column that places its bottom, between said copper insulated column and master control pcb board, is provided with insulating mat.
The invention has the advantages that simple in structurely, significant sealing affection can adapt to the abominable production operation environment in down-hole; Shock resistance is simultaneously installed quick and convenient.Combination table top between sensor housing and the sensor cover plate is provided with sealing gasket, and sensor housing and plug connector junction are filled with casting glue, has guaranteed the sealed damp-proof effect between them; The alignment pin that is arranged between sensor housing and the plug connector can prevent the rotation of plug connector and guarantee that front and back are spacing.
