Description

Technical Field

[0001] The utility model relates to the technical field of coal mine operations, in particular to a multi-component gas inspection device for coal mine operations. Background Art

[0002] Coal mines are the natural spaces humans create when they excavate coal-rich geological formations. Coal is the primary solid fuel and a type of combustible organic rock. Coal is a vital energy source, particularly suitable for power generation due to its affordability and abundant reserves. During coal mining operations, gas inspection devices are required to collect wired and wireless signals from underground multi-gas sensors, multi-gas detection alarms, multi-gas measurements, and other related instruments. These devices then upload data such as gas concentrations and corresponding location information to a ground-based central station computer for real-time monitoring.

[0003] Because the air in coal mines contains a lot of dust and impurities and is relatively humid, and the wire connectors are usually buckled into the wiring ports, there is a gap between the two. Dust and water vapor enter the body through the wiring ports, causing certain damage to internal parts, thereby shortening their service life. In addition, when the wires are subjected to external tension, the connectors are prone to loosening, resulting in poor contact. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 6 The utility model provides a multi-component gas inspection device for coal mine operations, comprising an inspection body 1 and an antenna 2 connected to the top of the inspection body 1. The bottom of the inspection body 1 is connected to a plurality of wiring ports 4, and the spacing between adjacent wiring ports 4 is equal. The bottom of the inspection body 1 is connected to a protective mechanism for covering the wiring ports 4, and the protective mechanism includes two protective covers 3, four connecting plates 6, a plurality of front pressure grooves 9, a plurality of rear pressure grooves 15, a plurality of sealing gaskets 16, and a plurality of arc-shaped pressure plates 13. The connecting plates 6 are used to guide the protective covers 3, the front pressure grooves 9 are provided at the front end of the protective covers 3, and the rear pressure grooves 15 are provided at the rear end of the protective covers 3. The sealing gaskets 16 are connected to the inner sides of the front pressure grooves 9 and the rear pressure grooves 15, and the arc-shaped pressure plates 13 are connected to the inner side of the protective covers 3. The protective covers 3 are connected to a locking mechanism for locking the two protective covers 3 together.

[0023] The two protective covers 3 can be driven toward each other and pressed together, so that the front pressing groove 9 presses against the wire 5 to achieve the positioning and fixation of the wire 5, and the rear pressing groove 15 presses against the wiring port 4. Combined with the use of the sealing gasket 16 and the sealing strip, the interior of the protective cover 3 is in a closed environment, effectively preventing external dust and water stains from entering the inspection body 1 through the wiring port 4, thereby extending the service life. At the same time, the arc-shaped pressure plate 13 presses against the joint 14, applying a forward thrust to the joint 14, so that the joint 14 and the wiring port 4 are firmly connected and the poor contact phenomenon is avoided.

[0024] Four slide grooves 8 are provided at the bottom of the inspection body 1. One end of the connecting plate 6 is slidably connected to the slide groove 8, and the other end is fixedly connected to the protective cover 3. When the protective cover 3 moves, the end of the connecting plate 6 slides in the slide groove 8, which can improve the stability of the reciprocating movement of the protective cover 3 and serve a good guiding purpose.

[0025] A spring 7 is provided in the slide groove 8, and both ends of the spring 7 are connected to the inspection body 1 and the connecting plate 6. When the two protective covers 3 are docked, the spring 7 is in an extended state. When the two protective covers 3 are loosened, the extended spring 7 quickly drives the protective covers 3 back to their original positions, thereby exposing the wiring port 4, making it convenient to operate the docking joint 14, saving time and effort.

[0026] The front pressing groove 9 and the rear pressing groove 15 are both semicircular structures. The front pressing groove 9 matches the wire 5, and the rear pressing groove 15 matches the wiring port 4.

[0027] The locking mechanism includes a connector 10, a positioning bolt 11, and a limiting seat 12. The connector 10 is connected to the upper protective cover 3, and the limiting seat 12 is connected to the lower protective cover 3. The connector 10 and the limiting seat 12 match, and the positioning bolt 11 is used to lock the connector 10. When the two protective covers 3 are connected, the positioning bolt 11 is rotated so that its end connects with the positioning groove to lock the connector 10 in place, improving the stability of the connection between the connector 10 and the limiting seat 12, that is, the two protective covers 3 are tightly and firmly connected.

[0028] The positioning bolt 11 is threadedly connected to the limiting seat 12 . A positioning groove is provided on the outer side of the connector 10 , and the end of the positioning bolt 11 matches the positioning groove.

[0029] An inclined surface is provided on the inner side of the arc-shaped pressure plate 13. When the two protective covers 3 are connected, the inclined surface is pressed against the connector 14, thereby applying a forward thrust to the connector 14, so that the connector 14 is firmly connected to the wiring port 4, and preventing the connector 14 from loosening and falling off when the wire 5 is subjected to external tension.

[0030] The end faces of the two protective covers 3 are connected with sealing strips, which improve the sealing performance of the connection between the two protective covers 3.

[0031] Working principle: After the connector 14 is docked with the wiring port 4, the two protective covers 3 are driven to approach each other, and the connector 10 is gradually inserted into the limit seat 12. After the two protective covers 3 are pressed against each other, the positioning bolt 11 is used to lock the connector 10 to improve the stability of the connection between the connector 10 and the limit seat 12, that is, the two protective covers 3 are tightly connected, and the spring 7 is in an elongated state. At the same time, the front pressure groove 9 is pressed against the wire 5, and the rear pressure groove 15 is pressed against the wiring port 4, and the use of the sealing gasket 16 and the sealing strip is combined to make the interior of the protective cover 3 a closed environment, effectively preventing external dust and water stains from entering the interior of the inspection body 1 through the wiring port 4, thereby extending the service life. The arc-shaped pressure plate 13 is pressed against the connector 14, and applies a forward thrust to the connector 14, so that the connector 14 is firmly docked with the wiring port 4, and the wire 5 is prevented from being subjected to external tension, causing the connector 14 to loosen, resulting in poor contact. When the connector 14 needs to be disassembled, the positioning bolt 11 is rotated to loosen the connector 10. At this time, the two protective covers 3 are in a relaxed state, and the stretched spring 7 drives the protective covers 3 to return to their original positions, that is, the two protective covers 3 move away from each other, exposing the connector 14 and the wiring port 4, making it easier to separate the connector 14 from the wiring port 4.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
