Description

Technical Field

[0001] The utility model relates to the technical field of mine safety equipment, in particular to a mine portable gas analyzer. Background Art

[0002] During the mining production process, various harmful gases may be produced in the mine, such as methane, carbon monoxide, hydrogen sulfide, etc. The presence of these gases poses a serious threat to the life safety of miners and the normal production of mines. Therefore, real-time monitoring and analysis of gases in mines is crucial. However, the existing portable gas analyzers still have the following problems in actual use:

[0003] Patent No. "CN202321892572.6" discloses a portable gas analyzer. When the device is in use, a lifting rod is arranged above the gas analyzer, so that the staff can lift the gas analyzer for transportation through the lifting rod. When carrying it on a relatively flat road, the first threaded rod is driven to rotate by turning the first knob, so that the movable plate drives multiple running wheels to move in the direction away from the gas analyzer. After the running wheels extend out of the mounting slot, the device is placed on the ground as a whole. At this time, the running wheels are in contact with the ground, and then the second threaded rod is driven to rotate by turning the second knob, thereby driving the slider and the lifting rod to move, and driving the handle to move until the plug is separated from the inside of the handle. At this time, the lifting rod and the handle are turned, and the staff can pull the handle to pull the device to move on the ground, so that there is no need to directly bear the weight of the gas analyzer. During use, the device is not provided with an anti-collision mechanism, which makes it impossible to ensure the safety of the device when it is hit, so that the life of the device is reduced and the safety is poor. In addition, the device cannot be positioned next to the operator during use, and the operator needs to hold it all the time, resulting in reduced portability and poor practicality of the device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-7 As shown, a portable gas analyzer for mining includes: a gas analyzer body 1, an anti-collision mechanism 2, a monitoring mechanism 3 and a positioning mechanism 4. The anti-collision mechanism 2 is arranged on the side of the gas analyzer body 1, and the monitoring mechanism 3 is arranged on the rear end of the anti-collision mechanism 2. The positioning mechanism 4 is connected to the side of the gas analyzer body 1. When the device is in use, the anti-collision mechanism 2 is used to prevent the gas analyzer body 1 from collision first, and then the monitoring mechanism 3 can be pulled out for auxiliary monitoring according to the use situation, and the device can be positioned by pulling the positioning mechanism 4, which is convenient for carrying.

[0025] The anti-collision mechanism 2 includes a first anti-collision block 21, a first slot 22 and a second anti-collision block 23. The first anti-collision block 21 is arranged on the side of the gas analyzer body 1. The first slot 22 is opened on the upper end of the first anti-collision block 21. The second anti-collision block 23 is arranged on the side of the gas analyzer body 1.

[0026] The second anti-collision block 23 is arranged at the lower end of the first anti-collision block 21, and bolts 24 are arranged on the sides of the first anti-collision block 21 and the second anti-collision block 23. When the device is in use, the first anti-collision block 21 and the second anti-collision block 23 are connected to the side of the gas analyzer body 1 by the bolts 24. Then, during use, the gas analyzer body 1 can be protected by the first anti-collision block 21 and the second anti-collision block 23 to prevent the gas analyzer body 1 from falling and being damaged.

[0027] The monitoring mechanism 3 includes a slide groove 31, a connecting rod 32, a telescopic rod 33, a first spring column 34 and a monitoring head 35. A slide groove 31 is provided on the side of the gas analyzer body 1, and a connecting rod 32 is connected to the inner side of the slide groove 31. The telescopic rod 33 is rotatably connected to the side of the connecting rod 32. The lower end of the telescopic rod 33 is connected to the monitoring head 35. The monitoring head 35 is provided with a groove, and a first spring column 34 is connected to the inner side of the slide groove 31. When the device is in use and when the device starts to monitor, the telescopic rod 33 is driven to rotate on the side of the connecting rod 32 by pulling the handle on the side of the telescopic rod 33. The second spring column 38 can assist the telescopic rod 33 to extend quickly, so that methane can be monitored through the monitoring head 35, and methane at different angles can be monitored through the monitoring head 35.

[0028] A second slot 36 is provided at the lower end of the slide slot 31, and two telescopic blocks 37 are symmetrically arranged on the inner side of the second slot 36, and two second spring columns 38 are symmetrically arranged on the inner side of the telescopic blocks 37. A first rotating rod 39 is rotatably connected between the two telescopic blocks 37. When the device is in use, when the telescopic rod 33 needs to be retracted, the handle on the side of the telescopic rod 33 is pulled to drive the telescopic rod 33 to rotate on the side of the connecting rod 32, so that the telescopic rod 33 retracts to the inner side of the slide slot 31. At this time, the telescopic block 37 arranged on the inner side of the second slot 36 pushes the first rotating rod 39 to extend upward through the second spring column 38. At this time, the first rotating rod 39 reaches the groove opened by the monitoring head 35 to limit the telescopic rod 33.

[0029] The positioning mechanism 4 includes a third card slot 41, a second rotating rod 42, a torsion spring 43, a connecting belt 44 and a hook 45. Two third card slots 41 are symmetrically opened on the side of the gas analyzer body 1. The second rotating rod 42 is rotatably connected inside the two third card slots 41. The torsion spring 43 is arranged on the side of the second rotating rod 42. The connecting belt 44 is arranged on the side of the second rotating rod 42. The connecting belt 44 is connected to the hook 45.

[0030] Two baffles 46 are symmetrically arranged on the side of the gas analyzer body 1, and the baffles 46 are consistent with the third slot 41. The connecting belt 44 passes through the baffles 46 and is connected to the hook 45. When the device is in use, the hook 45 is pulled to drive the connecting belt 44 to rotate on the side of the second rotating rod 42. At this time, the hook 45 can be hung on the operator or other places to facilitate carrying the gas analyzer body 1. At the same time, the torsion spring 43 is arranged to generate an opposite force to pull the connecting belt 44, so that the hook 45 is tighter when hanging to avoid loosening and falling off. At the same time, the baffle 46 can limit the hook 45 to prevent the hook 45 from reaching the third slot 41 during recovery and being inconvenient to be taken out.

[0031] When the utility model is used, the first anti-collision block 21 and the second anti-collision block 23 are first connected to the side of the gas analyzer body 1 by the bolt 24, and then the first anti-collision block 21 and the second anti-collision block 23 can be used to protect the gas analyzer body 1 during use to prevent the gas analyzer body 1 from falling and being damaged;

[0032] When the device starts monitoring, the handle on the side of the telescopic rod 33 is pulled to drive the telescopic rod 33 to rotate on the side of the connecting rod 32, and the second spring column 38 can assist the telescopic rod 33 to extend quickly, so that methane can be monitored through the monitoring head 35, and methane can be monitored at different angles through the monitoring head 35;

[0033] When the telescopic rod 33 needs to be retracted, the handle on the side of the telescopic rod 33 is pulled to drive the telescopic rod 33 to rotate on the side of the connecting rod 32, so that the telescopic rod 33 retracts to the inside of the slide groove 31. At this time, the telescopic block 37 provided on the inside of the second card groove 36 pushes the first rotating rod 39 to extend upward through the second spring column 38. At this time, the first rotating rod 39 reaches the groove provided in the monitoring head 35, and the telescopic rod 33 is limited.

[0034] During use, the hook 45 is pulled to drive the connecting belt 44 to rotate on the side of the second rotating rod 42. At this time, the hook 45 can be hung on the operator or other places to facilitate carrying the gas analyzer body 1. At the same time, the torsion spring 43 generates an opposite force to pull the connecting belt 44, so that the hook 45 is tighter when hanging to avoid loosening and falling off. At the same time, the baffle 46 can limit the hook 45 to prevent the hook 45 from reaching the third card slot 41 when it is recovered and is inconvenient to be taken out.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
