Description

Technical Field

[0001] The utility model relates to the technical field of mining sensors, in particular to a multifunctional drilling emergency sensor. Background Art

[0002] In industrial production and engineering operations, drilling operation is one of the common and critical processes, especially mine drilling. In order to ensure the safety and efficiency of the drilling process, the detection of the drilling environment and related parameters is very important.

[0003] Most detection equipment can only detect a single parameter and cannot fully and comprehensively reflect the actual situation of drilling. In complex drilling operations, only detecting a single parameter such as temperature or pressure may not be able to timely discover potential safety hazards. On the other hand, in emergency situations, existing sensors lack effective protection mechanisms and are easily damaged, thus affecting the continuity and accuracy of detection work. To this end, we propose a multifunctional drilling emergency sensor. Utility Model Content

[0006] A detection component is provided in the inner cavity of the connecting tube, a motor is installed on the inner side of the connecting tube, the output end of the motor passes through the connecting tube, a turntable is fixedly installed on the output end of the motor, two connecting plates are welded on the outer side of the turntable, a movable plate is welded at one end of the connecting plate, and a sealing piece for blocking the air inlet and outlet ducts is installed on the surface of the movable plate.

[0008] Preferably, the detection component is specifically two sensor mounting plates, the sensor mounting plates are fixedly installed in the inner cavity of the connecting pipe, a temperature and humidity sensor is installed on the surface of one of the sensor mounting plates, and a gas sensor is installed on the surface of the other sensor mounting plate.

[0010] Preferably, a cleaning brush is installed on the surface of the movable plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This multifunctional drilling emergency sensor buries the stress sensor in the area where stress detection is required, so that the connecting pipe passes through the coal seam in the mine, one end of the connecting pipe is exposed to the air, and one end of the air outlet pipe and the air inlet pipe are exposed to the air. Turn on the fan switch to allow external air to enter the connecting pipe from the air inlet pipe and leave from the air outlet pipe. The temperature sensors and gas sensors installed on the surface of multiple sensor mounting plates can detect various parameters during drilling in the mine, so as to discover hidden dangers in time.

[0013] 2. The multifunctional drilling emergency sensor can prevent dust from entering the air inlet pipe, connecting pipe and air outlet pipe through the first filter plate, which may affect the performance of various components in the connecting pipe. When an emergency occurs during the drilling process, the motor can be controlled to turn on to drive the turntable, connecting plate and movable plate to rotate. When the movable plate rotates, two cleaning brushes first clean the surface of the first filter plate and the second filter plate, and then the movable plate drives the block to rotate to the position blocking the first filter plate and the second filter plate, thereby blocking the air inlet pipe and the air outlet pipe. At this time, the connecting pipe buried in the coal seam of the mine is in a closed state, thereby protecting the motor, the sensor mounting plate and the sensor installed on the surface of the sensor mounting plate, thereby improving its safety.

[0021] Specifically, through the rotatable blocking piece, during normal operation, the air inlet pipe 3 and the air outlet pipe 5 are used for air intake and air exhaust respectively, and the external air is pumped into the connecting pipe 2 buried in the coal seam for detection. In an emergency, the blocking piece is rotated to block the air inlet pipe 3 and the air outlet pipe 5, thereby closing the connecting pipe 2, the air inlet pipe 3, and the air outlet pipe 5 to protect the internal components.

[0022] Among them: the longitudinal position of the detection component is located between the connection between the air inlet pipe 3 and the connecting pipe 2 and the connection between the air outlet pipe 5 and the connecting pipe 2. The detection component is specifically two sensor mounting plates 8. The sensor mounting plates 8 are fixedly installed in the inner cavity of the connecting pipe 2. A temperature and humidity sensor is installed on the surface of one sensor mounting plate 8, and a gas sensor is installed on the surface of the other sensor mounting plate 8. The temperature sensors and gas sensors installed on the surfaces of multiple sensor mounting plates 8 can detect various parameters during drilling in the mine, so as to discover hidden dangers in time.

[0023] Wherein: a blocking block 13 is fixedly installed on the surface of the movable plate 12, and the two blocking blocks 13 are respectively used to block the air outlet pipe 5 and the air inlet pipe 3.
