Description

Technical Field

[0001] This utility model belongs to the field of mine safety monitoring technology and relates to a smoke sensor, specifically a smoke sensor for monitoring mine fires. Background Technology

[0002] To provide early warning of fire hazards in mine tunnels, smoke detectors are typically installed. Current installation methods generally involve drilling holes in the tunnel wall at suitable locations, inserting expansion bolts, and then securing the smoke detector to the bolts using a matching mounting plate and nuts. This method is extremely robust and suitable for installation on relatively flat and sturdy tunnel walls, capable of withstanding a certain amount of impact and vibration. It is commonly used in open areas with stable surrounding rock, such as main tunnels and chambers. However, replacing smoke detectors with this installation structure requires specialized tools, which is time-consuming and cumbersome.

[0003] Existing patent CN 218181111 U discloses a micro-vibration monitoring safety device for non-coal mines, including a first mounting plate and a second mounting plate. A micro-vibration sensor is fixedly connected to the middle of the side of the first mounting plate away from the second mounting plate. Multiple limiting slots are opened on one side of the first mounting plate. Multiple limiting plates adapted to the limiting slots are fixedly connected to one side of the second mounting plate. Movable grooves are opened on one side of both ends of the limiting plates, and limiting blocks are slidably arranged on the inner wall of the movable grooves. Multiple compression springs are fixedly installed between the limiting blocks and the movable grooves. An installation rod is fixedly connected to the middle of the side of the second mounting plate away from the first mounting plate. This structure realizes the installation and disassembly of the sensor through threaded rods, threaded sleeves, limiting blocks, movable grooves, compression springs, etc. Although its advantage is that it is easy to install and disassemble the micro-vibration sensor, its structure is too complex, which not only increases the cost, but also makes the device prone to detachment and damage due to the large number of small parts.

[0028] The fixing assembly 3 comprises a fixing block 9, a fixing plate 13 and a U-shaped block 12. The fixing block 9 is located on the top of the smoke sensor body 1. The fixing block 9 is in the shape of a ring, and third inserting holes 11 are uniformly distributed on the fixing block 9. The third inserting holes 11 are used for cooperating with the first inserting rod 6. The fixing plate 13 is located directly above the fixing block 9, and four protruding connecting legs are uniformly distributed on the outer edge of the fixing plate 13.

One end of the U-shaped block 12 is connected to the side wall of the fixing block 9, and the other end of the U-shaped block 12 is connected to the side wall of the fixing plate 13, so that a rotating groove 10 is formed between the fixing block 9 and the fixing plate 13. Threaded holes are formed in the side walls of the U-shaped blocks 12. When the first inserting rod 6 is inserted along the third inserting holes 11, the top wall of the smoke sensor body 1 is in contact with the bottom wall of the fixing block 9.

[0029] The rotating assembly 4 comprises a rotating ring 14, an inserting plate 15 and a pushing rod 17. The rotating ring 14 is in the shape of a ring and is rotatably connected in the rotating groove 10. Four uniformly distributed pushing rods 17 and four uniformly distributed inserting plates 15 are fixedly connected to the outer wall of the rotating ring 14. The pushing rod 17 is used for rotating the rotating ring 14. The inserting plate 15 is in the shape of L and is composed of a short plate and a long plate. The short plate is connected to the rotating ring 14, and the long plate is provided with a fourth inserting hole 16. The fourth inserting hole 16 corresponds to the second inserting hole 8 and the threaded hole of the U-shaped block 12.

[0030] When the first plug rod 6 is inserted into the third insertion hole 11, the rotating lever 17 is rotated to make the rotating ring 14 drive the plug plate 15 to be inserted into the first insertion hole 7, at this time, the threaded hole is located on the same straight line with the corresponding second insertion hole 8 and fourth insertion hole 16, and then the threaded assembly 5 is inserted; the first plug rod 6 is fixedly connected with the fixed assembly 3 and the rotating assembly 4, so that the smoke sensor body 1 is fixed on the top of the roadway.

[0032] The diameter of the second plug rod 20 is smaller than the outer diameter of the threaded rod 18, and the threaded rod 18 is rotated on the U-shaped block 12, so that the second plug rod 20 is taken out of the threaded hole of the U-shaped block 12, thereby facilitating replacement.

[0033] As described above, the mine fire monitoring smoke sensor is used in the top of the roadway of the mine, a hole is opened by using a tool, and then the expansion bolts are inserted into the hole opened in the top of the roadway through the fixing holes of the fixed plate 13, and the fixed plate 13 is fixed on the top of the roadway of the mine by rotating the expansion bolts using a tool.

[0034] The smoke sensor body 1 is held by hand, the first plug rod 6 is inserted along the third insertion hole 11, and the second insertion hole 8 is aligned with the threaded hole; then the rotating lever 17 is rotated to make the rotating ring 14 drive the plug plate 15 to be inserted into the first insertion hole 7 of the first plug rod 6, the plug plate 15 is limited to the first plug rod 6, at the same time, the fourth insertion hole 16 corresponds to the second insertion hole 8 and the threaded hole, and then the smoke sensor body 1 is installed on the fixed assembly 3.

[0035] The second plug rod 20 is inserted into the threaded hole of the U-shaped block 12, and the rotating handle 19 is rotated, the threaded rod 18 is rotated and advanced in the threaded hole, and drives the second plug rod 20 to enter the fourth insertion hole 16 and the second insertion hole 8, the second insertion hole 8 limits and fixes the plug plate 15, and blocks the rotating ring 14 from driving the plug plate 15 to rotate.

[0036] When the smoke sensor body 1 needs to be replaced, the hand rotates the handle 19, and the threaded rod 18 drives the second insertion rod 20 to move away from the second insertion hole 8 and the fourth insertion hole 16, thereby making the second insertion rod 20 disengage from the second insertion hole 8 and the fourth insertion hole 16, until disengagement, then rotating the lever 17, the rotating ring 14 drives the insertion plate 15 to disengage from the first insertion rod 6, holding the smoke sensor body 1, and the first insertion rod 6 slides along the third insertion hole 11 downward until disengagement, thereby facilitating the disassembly of the smoke sensor body 1.

[0037] When installing a new smoke sensor body 1, only need to insert the first insertion rod 6 into the third insertion hole 11, then rotate the lever 17, so that the insertion plate 15 enters the first insertion hole 7 of the first insertion rod 6, then insert the second insertion rod 20 into the threaded hole of the U-shaped block 12, then rotate the handle 19, so that the threaded rod 18 drives the second insertion rod 20 to enter the second insertion hole 8 and the fourth insertion hole 16, thereby fixing the smoke sensor body 1.
