Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining safety technology, specifically a detection device for methane detection in mining areas. Background Technology
[0002] my country is the world's largest emitter of anthropogenic methane, with the coal industry accounting for approximately one-third of the total emissions. Between 2010 and 2015, methane emissions from China's coal industry accounted for 11%-24% of the global increase in methane emissions. Focusing on my country's coal industry and effectively managing methane emissions in key coal-producing regions are crucial for controlling the continuous growth of methane emissions and mitigating climate change.
[0003] Currently, handheld methane detection devices are generally used to detect methane in enclosed spaces, enabling rapid on-site methane detection. These devices are characterized by their simple structure, small size, and portability.
[0004] However, when using existing handheld methane detection devices, operators are prone to accidentally pressing buttons on the device, causing inconvenience and thus lacking practicality. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a detection device for methane detection in mining areas, which has the advantage of avoiding accidental button presses and solves the problem of accidental button presses during use.
[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a methane detection device for mining areas, characterized in that it includes a methane detector body; the methane detector body is provided with a protective device, the protective device including: a U-shaped plate, fixedly connected to the outer wall of the methane detector body; a groove, formed on the front surface of the U-shaped plate; a limiting block, inserted into the groove and slidably connected to the U-shaped plate; a moving plate, fixedly connected to the outer wall of the limiting block and slidably connected to the inside of the U-shaped plate; a spring, disposed on the moving plate; a shielding plate, hinged to the front surface of the U-shaped plate; and a limiting frame, fixedly connected to the rear surface of the shielding plate.
[0007] Preferably, a pull plate is fixedly connected to the top of the limiting block.
[0008] Preferably, the limiting block has an inclined surface on one side.
[0009] Preferably, the movable plate is provided with a damper.
[0010] Preferably, the outer wall of the U-shaped plate and the front surface of the limiting frame are provided with multiple anti-slip grooves.
[0011] Preferably, the movable plate is provided with multiple springs.
[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a detection device for methane detection in mining areas, which has the following beneficial effects: This invention has the advantage of preventing accidental button presses. The operator rotates the baffle by hand, causing the baffle to move its upper limit frame simultaneously. Then, the operator pulls the limit block upward. When the baffle is in close contact with the U-shaped plate, the limit frame is precisely inserted into the groove. The operator then releases the limit block, at which point the spring squeezes the limit block into the inside of the limit frame, limiting both the limit frame and the baffle. This effectively blocks the button press during testing, thus solving the problem of accidental button presses during use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0016] See Figure 1-4A methane detection device for mining areas, characterized in that it includes a methane detector body 1; a protective device 2 is provided on the methane detector body 1, the protective device 2 including: a U-shaped plate 21, fixedly connected to the outer wall of the methane detector body 1; a groove 22, formed on the front surface of the U-shaped plate 21; a limiting block 23, inserted into the groove 22 and slidably connected to the U-shaped plate 21; a moving plate 24, fixedly connected to the outer wall of the limiting block 23 and slidably connected to the inside of the U-shaped plate 21; a spring 25, disposed on the moving plate 24; a shielding plate 26, hinged to the front surface of the U-shaped plate 21; a limiting frame 27, fixedly connected to the rear surface of the shielding plate 26; a pull plate 4 fixedly connected to the top of the limiting block 23; and an inclined surface provided on one side of the limiting block 23.
[0017] When ready for use, the operator turns on the methane detector body 1 and then manually rotates the baffle 26, causing it to move simultaneously with its upper limit frame 27. The operator then pulls the limiting block 23, causing it to move the moving plate 24 upwards and compress the spring 25. When the baffle 26 is flush with the U-shaped plate 21, the limiting frame 27 is precisely inserted into the groove 22. The operator then releases the limiting block 23, at which point the spring 25 compresses the moving plate 24 and causes the limiting block 23 to move downwards, inserting it inside the limiting frame 27. This limits the position of the limiting frame 27 while simultaneously controlling the baffle. The baffle 26 simultaneously limits the movement of the button, thus preventing accidental button presses during testing and improving the practicality of the device. When the operator pulls the pull plate 4, the limiting block 23 moves upward simultaneously, preventing the limit block 23 from slipping off the operator's fingers due to its smooth and small surface, thereby improving the stability of the device. When the operator rotates the baffle 26 to move the limiting frame 27 simultaneously, the limiting frame 27 enters the groove 22 and presses one side of the inclined surface of the limiting block 23, causing the limiting block 23 to move automatically without the need for manual pulling, thus improving the operator's work efficiency. Example 2
[0018] See Figure 1-4 Based on Embodiment 1, auxiliary functions have been added; The movable plate 24 is provided with a damper 6; the outer wall of the U-shaped plate 21 and the front surface of the limiting frame 27 are provided with multiple anti-slip grooves 5; the movable plate 24 is provided with multiple springs 25.
[0019] In use, when the limiting block 23 limits the limiting frame 27, external shaking causes the spring 25 to shake, which in turn causes the limiting block 23 to shake simultaneously via the moving plate 24. At this time, the damper 6 reciprocates with the vibration structure via the damping rod, driving the piston to move in the cylinder filled with hydraulic oil. The small holes or gaps on the piston force the hydraulic oil to pass through, generating viscous resistance and internal friction between fluid molecules, converting the vibration kinetic energy into heat energy for dissipation. This prevents the limiting block 23 from sliding out of the limiting frame 27 due to shaking, thus improving the stability of the device. The multiple anti-slip grooves 5 on the moving plate 24 can increase the friction between the operator's hand and the device, reducing the possibility of slippage during use, thereby improving the safety of the device. The multiple springs 25 can further increase the pressure on the moving plate 24 through the elastic force of the multiple springs 25, further preventing the limiting block 23 from separating from the limiting frame 27 due to shaking, thus further improving the stability of the device.
[0020] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
