DETAILED DESCRIPTION

[0020] 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.

[0021] When implementing: Figure 1-5 As shown, a methane detection alarm for mining includes: a methane detection alarm body 1, an anti-collision mechanism 5, a positioning mechanism 6 and an automatic detection mechanism 7. A switch 2 is arranged at the lower side of the front end of the methane detection alarm body 1, an alarm horn 3 is connected to the upper side of the front end of the methane detection alarm body 1, a warning light 4 is connected to the upper side of the front end of the methane detection alarm body 1, and the warning light 4 is arranged on the side of the alarm horn 3. An anti-collision mechanism 5 is arranged on the side of the methane detection alarm body 1, a positioning mechanism 6 is arranged at the rear end of the methane detection alarm body 1, and an automatic detection mechanism 7 is slidably connected to the front end of the methane detection alarm body 1. When the device is in During use, the methane detection alarm body 1 is started by pressing the switch 2. When the methane concentration is detected to be too high during use, an alarm is sounded through the alarm speaker 3 and the warning light 4 to remind the operator. The anti-collision mechanism 5 can protect the methane detection alarm body 1. When the operator is unable to hold the methane detection alarm body 1 for a long time for detection, the methane detection alarm body 1 can be positioned on the side of the wall through the positioning mechanism 6. At the same time, the methane detection alarm body 1 is timed to be switched on and off through the automatic detection mechanism 7, which is convenient for long-term detection and improves the overall practicality of the device.

[0022] The anti-collision mechanism 5 includes a first anti-collision block 51, a second anti-collision block 52 and a bolt 53. The first anti-collision block 51 is connected to the side of the upper end of the methane detection alarm body 1, and the second anti-collision block 52 is connected to the side of the lower end of the methane detection alarm body 1. Bolts 53 are symmetrically arranged on the sides of the first anti-collision block 51 and the second anti-collision block 52. When the device is in use, the methane detection alarm body 1 is protected by the first anti-collision block 51 and the second anti-collision block 52.

[0023] The positioning mechanism 6 includes a first shell 61, a first slider 62, a positioning plate 63 and a positioning hole 64. The first shell 61 is connected to the rear end of the methane detection alarm body 1. Two first sliders 62 are symmetrically slidably arranged inside the first shell 61. Positioning plates 63 are arranged on the sides of the two first sliders 62. Positioning holes 64 are opened at equal distances on the surface of the positioning plate 63.

[0024] A connecting plate 65 is connected to the side of the positioning plate 63, and the connecting plate 65 is arranged on the outside of the first shell 61. A handle 66 is connected to the side of the connecting plate 65. A first spring column 67 is equidistantly arranged between the two first sliders 62. When the device is in use, the positioning plate 63 is driven to slide out by pulling the handle 66 on the side of the first shell 61, and the positioning plate 63 is positioned through the positioning hole 64 opened on the side of the positioning plate 63. When the device needs to be removed, the positioning pile is removed. At this time, the first spring column 67 and the first slider 62 drive the positioning plate 63 to retract into the first shell 61. At the same time, the connecting plate 65 is set to limit the positioning plate 63 for easy removal next time.

[0025] The automatic detection mechanism 7 includes a card plate 71, a gripper 72, a motor 73, a connecting block 74 and a protrusion 75. A card slot is provided at the front end of the methane detection alarm body 1, and a card plate 71 is slidably provided in the card slot. A gripper 72 is provided at the lower end of the card plate 71, and a motor 73 is connected to the upper end of the card plate 71. A connecting block 74 is connected to the side of the output shaft of the motor 73, and a protrusion 75 is provided on the side of the connecting block 74. The connecting block 74 is parallel to the switch 2.

[0026] A groove is provided at the upper end of the slot, and a second shell body 76 is provided inside the groove. The second shell body 76 is slidably connected to a second slider 78, and the second slider 78 is rotatably connected to a rotating block 79. A limiting groove is provided at the upper end of the card plate 71, and the limiting groove coincides with the rotating block 79. When the device is in use, when the methane detection alarm body 1 is installed on the side wall of the mine, the card plate 71 is inserted into the card slot, and the second slider 78 is pushed by the second spring column 77 to squeeze the card plate 71 so that the card plate 71 is fully inserted into the card slot. At this time, the rotating block 79 connected by the second slider 78 rotates and coincides with the limiting groove provided at the upper end of the card plate 71, limiting the card plate 71. At this time, the starting motor 73 drives the connecting block 74 to rotate slowly. When the protrusion 75 provided on the side of the connecting block 74 contacts the switch 2, it will drive the methane detection alarm body 1 to be opened or closed once, so that the device can be automatically detected when unattended.

[0027] When the utility model is used, the methane detection alarm body 1 is first started by pressing the switch 2 during use. When the methane concentration is detected to be too high during use, an alarm is sounded through the alarm speaker 3 and the warning light 4 to remind the operator;

[0028] The first anti-collision block 51 and the second anti-collision block 52 are installed on the side of the methane detection alarm body 1 by means of bolts 53, and the methane detection alarm body 1 is protected by the first anti-collision block 51 and the second anti-collision block 52;

[0029] When it is inconvenient for the operator to hold the methane detection alarm body 1, the handle 66 on the side of the first shell 61 is pulled to drive the positioning plate 63 to slide out, and the positioning plate 63 is positioned through the positioning hole 64 provided on the side of the positioning plate 63. When the device needs to be removed, the positioning pile is removed. At this time, the first spring column 67 provided inside the first shell 61 pulls the first slider 62 back, and the first slider 62 drives the positioning plate 63 back to the inside of the first shell 61. The provided connecting plate 65 limits the positioning plate 63, which is convenient for taking out next time.

[0030] When the methane detection alarm body 1 is installed on the side wall of the mine, the card plate 71 is inserted into the card slot. At this time, the second shell 76 arranged inside the card slot pushes the second slider 78 to squeeze the card plate 71 through the second spring column 77 inside the second shell 76. When the card plate 71 is fully inserted into the card slot, the rotating block 79 connected by the second slider 78 rotates and matches the limiting groove opened at the upper end of the card plate 71 to limit the card plate 71. At this time, the starting motor 73 drives the connecting block 74 to rotate slowly. When the protrusion 75 set on the side of the connecting block 74 contacts the switch 2, it will drive the methane detection alarm body 1 to open or close once, so that the device can perform automatic detection when unattended.

[0031] 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.
