Description

Technical Field

[0001] This utility model relates to the field of coal mine safety monitoring technology, and in particular to an intelligent air pressure linkage dust and gas monitoring system. Background Technology

[0002] Coal mine safety monitoring is a crucial means of ensuring safe production in coal mines. It primarily involves dynamically monitoring key parameters such as methane, carbon monoxide concentration, temperature, and wind speed underground to prevent accidents. A typical coal mine safety monitoring system consists of a central station, substations, sensors, actuators, and a power supply. Sensors collect various parameters underground, substations transmit the data to the central station, and the central station handles data processing, analysis, and alarm generation.

[0003] In existing technologies, coal dust (especially coal dust) in coal mines adheres to the surface of gas sensors, forming an isolation layer that hinders the contact between gas and the sensor. Dust accumulation may cause the sensor to respond slowly, failing to alarm in time when the gas concentration rises rapidly, or certain components in the dust may cause cross-sensitivity, leading to false alarms. Therefore, a gas monitoring device that can handle dust is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent air pressure linkage dust removal and gas monitoring system, which can facilitate the removal of dust from the sensor surface, so as to solve the problem that when existing gas monitoring devices are used, underground coal mine dust will adhere to the sensor surface, forming an isolation layer and hindering contact with the sensor.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an intelligent air pressure linkage dust removal and gas monitoring system, including a protective shell, wherein the protective shell is internally equipped with a multi-parameter sensing module, an intelligent control unit, a dust removal device, a data communication module and an early warning alarm module;

A pressure structure is fixedly connected to the top of the protective housing, and both sides of the pressure structure cooperate with the interior of the filter structure.

[0007] Furthermore, the filter structure includes a first connecting pipe, the bottom of which extends into the interior of the protective housing. The top and bottom of the first connecting pipe near the protective housing are both fixedly connected to connecting pipes. A sealing plate is fixedly connected to the surface of the connecting pipe. A filter frame is fixedly connected to the left side of the sealing plate. One side of the filter frame extends through the protective housing and reaches the surface of the protective housing. Vents are provided at the four corners of the connecting pipe surface, located inside the filter frame. A guide plate is fixedly connected to the left side of the filter frame. One side of the first connecting pipe is fixedly connected to the surface of the pressurization structure.

[0008] Furthermore, the pressurization structure includes a servo motor located at the top of the protective housing. A support frame is fixedly connected to the surface of the servo motor, and the bottom of the support frame is fixedly connected to the top of the protective housing. An abutment protrusion is fixedly connected to the output end of the servo motor. Abutment blocks are provided on both sides of the surface of the abutment protrusion. A guide rod is fixedly connected to the other side of the abutment block. A second connecting tube is sleeved on the surface of the guide rod. One side of the second connecting tube is fixedly connected to the interior of the first connecting tube. A sealing plug is fixedly connected to the side of the guide rod away from the abutment block. The surface of the sealing plug is tightly fitted to the interior of the second connecting tube.

[0009] Furthermore, a sleeve is fitted onto the surface of the filter frame, and a drawer is detachably connected to the bottom of the sleeve. A through hole is provided at the bottom of the sleeve, and the bottom of the through hole is used in conjunction with the drawer. The sealing plate and the sleeve are fixedly connected to the inner wall of the protective shell by bolts.

[0010] Furthermore, the surface of the filter frame is fitted with a tapered protrusion ring, and there are several tapered protrusion rings. The surface of the tapered protrusion ring is fixedly connected to the inner wall of the sleeve.

[0011] Furthermore, a tension spring is fitted onto the surface of the guide rod, with the left side of the tension spring fixedly connected to the surface of the sealing plug and the right side of the tension spring fixedly connected to the inner wall of the second connecting tube.

[0012] Furthermore, a reinforcing sleeve is fitted onto the surface of the guide rod, and the surface of the reinforcing sleeve is fixedly connected to the interior of the second connecting tube.

[0013] The beneficial effects of this utility model are:

The guide plate helps guide the substances into the surface of the filter frame. The first connecting pipe is fixedly connected to the pressurization structure, which facilitates the cleaning of impurities on the surface during the filtration process.

[0016] 3.
