Description

Technical Field

[0001] The utility model relates to the technical field of life detection equipment, in particular to a life detector for coal mine rescue. Background Art

[0002] As an important part of the energy industry, the safe production of coal mines is directly related to the life safety of miners and social stability. Once a coal mine accident occurs, rapid and effective rescue operations can minimize casualties and property losses. The life detector is a key rescue tool in coal mine rescue. It is a life-saving device that uses audio, video, radar, infrared and other technologies to detect human vital signs for disaster rescue. It can help rescuers quickly and accurately locate the position of trapped miners, provide key information for rescue operations, and thus implement effective rescue operations.

[0003] However, in coal mine rescue, rescuers cannot reach into the collapsed position of the mine, and need to hold the probe rod handle and extend the probe rod into the narrow collapsed space for exploration. Most of the existing life detector probe rods use telescopic rods to extend their lengths, increase the insertion depth of the wireless detection probe, and cannot adjust the detection angle of the wireless detection probe, which has certain limitations. Therefore, those skilled in the art provide a life detector for coal mine rescue to solve the problems raised in the above background technology. Utility Model Content

[0022] In one embodiment, when using the detection rod 1, the metal hose 4 can be bent first to allow the metal hose 4 to drive the wireless detection probe 5 to bend on the detection rod 1, and the detection angle of the wireless detection probe 5 can be adjusted. Then, the position of the wireless detection probe 5 with the adjusted angle can be fixed by the characteristics of the metal hose 4 itself to prevent the angle of the wireless detection probe 5 from being offset after the position is adjusted. Then, the telescopic inner rod 32 can be slid out of the telescopic outer rod 31, the telescopic rod 3 can be unfolded, and the length of the detection rod 1 can be extended. The wireless detection probe 5 can be extended into the collapsed space in the mine by the extended detection rod 1, so as to explore the collapsed space in the mine. The unfolding length of the telescopic rod 3 can be adjusted according to the exploration environment, and the extension length of the detection rod 1 can be controlled. The wireless detection probe 5 on the detection rod 1 can be extended into positions of different depths for exploration, thereby realizing the exploration of collapsed spaces of different depths.

[0023] In one embodiment, since the telescopic rod 3 has its own positioning mechanism, the positioning mechanism is a spring-type button buckle on the telescopic rod 3 in the prior art. When the telescopic rod 3 is unfolded, the spring-type button buckle on the telescopic inner rod 32 can be engaged in the slot on the telescopic outer rod 31, thereby limiting the positions of the telescopic inner rod 32 and the telescopic outer rod 31, preventing the displacement of the telescopic inner rod 32 and the telescopic outer rod 31 after unfolding, thereby ensuring the use of the telescopic rod 3.

[0024] In one embodiment, when the detection angle of the wireless detection probe 5 is adjusted after the wireless detection probe 5 is extended into the collapsed space, the telescopic outer rod 31 can be rotated on the bearing seat 23 in the empty groove 221 through the bearing, and the telescopic outer rod 31 drives the other telescopic outer rod 31 connected to it through the telescopic inner rod 32 to rotate, and drives the wireless detection probe 5 installed on the other telescopic outer rod 31 through the metal hose 4 to rotate, so that the detection angle of the wireless detection probe 5 can be adjusted, and the collapsed space can be fully detected through the wireless detection probe 5, avoiding the situation that the wireless detection probe 5 on the detection rod 1 cannot fully detect the collapsed space due to the fixed angle, and the practicability is strong.

[0025] In one embodiment, when the telescopic outer rod 31 is driven to rotate, since a limiting groove 312 is provided at a position corresponding to the inner wall of the cavity 311 and the limiting slide block 321, the limiting slide block 321 is slidably installed inside the limiting groove 312, and the telescopic inner rod 32 in the cavity 311 can be limited by the limiting slide block 321 and the limiting groove 312, and then the position of the limiting slide block 321 is limited by the annular baffle plate 33 at the end of the telescopic outer rod 31, so that the telescopic inner rod 32 slides in the through opening 331, and the limiting slide block 321 is prevented from being separated from the limiting groove 312, and the telescopic inner rod 32 is prevented from being separated from the telescopic outer rod 31 and rotating inside the telescopic outer rod 31, thereby ensuring the rotation of the telescopic rod 3 and facilitating the angle adjustment of the wireless detection probe 5.

[0026] In one embodiment, after adjusting the detection angle of the wireless detection probe 5, the limit cylinder 34 can be screwed on the outer wall of the telescopic outer rod 31 through the cooperation of the threaded hole 341 and the threaded ring 313, so that the limit cylinder 34 can be displaced on the outer wall of the telescopic outer rod 31 toward the handle 2, and then the limit cylinder 34 can be threadedly installed on the outer wall of the external threaded cylinder 22 through the threaded groove 342 and tightly attached to the end face of the annular end plate 21. The telescopic outer rod 31 rotating on the external threaded cylinder 22 is limited by the limit cylinder 34 to prevent the telescopic outer rod 31 from rotating, thereby avoiding the situation where the wireless detection probe 5 installed thereon through the metal hose 4 is driven to rotate due to the rotation of the telescopic outer rod 31, thereby realizing the limitation of the wireless detection probe 5 after the angle is adjusted.

[0027] The working principle of the utility model is as follows: when using the detection rod 1 for rescue, the metal hose 4 can be bent to allow the metal hose 4 to drive the wireless detection probe 5 to bend on the detection rod 1, and then the position of the bent wireless detection probe 5 is fixed by the characteristics of the metal hose 4 itself to prevent the deviation of the wireless detection probe 5 after the position is adjusted, and then the telescopic inner rod 32 is slid out of the telescopic outer rod 31, the telescopic rod 3 is unfolded, and the length of the detection rod 1 is extended. The wireless detection probe 5 is extended into the collapsed space in the mine by the extended detection rod 1, and the collapsed space in the mine can be explored. At the same time, the telescopic outer rod 31 installed on the bearing seat 23 through the bearing is rotated, and the telescopic outer rod 31 drives another telescopic outer rod 31 connected to it through the telescopic inner rod 32 to rotate, and drives the telescopic outer rod 31 installed on the other telescopic outer rod 31 through the metal hose 4. The wireless detection probe 5 on the upper part is rotated to adjust the detection angle of the wireless detection probe 5, and then the limiting cylinder 34 is twisted, and one end of the limiting cylinder 34 threadedly installed on the outer wall of the telescopic outer rod 31 is threadedly installed on the outer wall of the external threaded cylinder 22 and is close to the end surface of the annular end plate 21, and the position of the telescopic outer rod 31 is limited by the limiting cylinder 34 to prevent the telescopic outer rod 31 from rotating, thereby completing the limiting of the wireless detection probe 5 after the adjusted angle, and finally, the telescopic rod 3 is continuously extended into the collapsed space for exploration, so that a certain direction in the collapsed space can be explored, and the detection angle of the wireless detection probe 5 can be adjusted, so that the wireless detection probe 5 can conduct an all-round exploration of the collapsed space, thereby avoiding the situation that the wireless detection probe 5 on the detection rod 1 cannot fully explore the collapsed space due to the fixed angle, thereby improving the rescue efficiency and effect, and having strong practicality.
