[0002] If coal seam gas is not controlled, it will surge out in large quantities during mining, causing gas exceedances, explosions, and outbursts, threatening miners' lives and affecting normal coal mine production. Controlling gas concentrations can eliminate safety hazards and ensure safe production; it is a necessary measure for safe coal mining. Coal seam gas control requires the use of rapid gas analyzers, as gas content is the core data for control, and traditional methods are time-consuming and difficult to monitor dynamically. Rapid gas analyzers can measure underground, providing real-time and accurate data, adapting to intelligent control, reducing safety risks, and meeting regulatory and efficiency requirements; they are the "eyes" of gas control. Existing rapid gas analyzers have compact and small main unit buttons to achieve functional integration. However, the underground working environment in coal mines is complex, requiring workers to wear thick, wear-resistant work gloves to protect their hands. These gloves increase the contact area between fingers and buttons, making it difficult to accurately locate the pressing area during operation, easily leading to accidental presses.

[0024] Example

[0025] like Figures 1 to 4As shown, the present invention proposes a coal seam gas control device, including a rapid gas analyzer main unit 1. The upper surface of the rapid gas analyzer main unit 1 is also provided with a pair of connectors 12, which are used for inter-device connection or external attachment to expand the device's functionality. A cover 4 is rotatably connected to the top of the rapid gas analyzer main unit 1. A support 2 is fixedly connected to the upper surface of the rapid gas analyzer main unit 1. The upper surface of the rapid gas analyzer main unit 1 is provided with multiple buttons 11 arranged in a circular array around the support 2. The buttons 11 are used for function operation and data interaction, serving as the control entry point for the instrument.

[0026] Among them, such as Figures 2 to 4 As shown, a rotating mechanism is installed on the top of the support 2, which is manually driven to press the corresponding button 11. The rotating mechanism includes a retaining ring 21 fixedly connected to the top of the support 2. The retaining ring 21 cooperates with the retaining plate 32 to limit the rotation path and range of the rotating mechanism. A connecting rod 31 is movably inserted into the top of the support 2. One end of the connecting rod 31 inserted into the support 2 is fixedly connected to the retaining plate 32 that holds the retaining ring 21. The retaining plate 32 rotates with the connecting rod 31, and its groove 33 indicates that it corresponds to the position of the button 11. A support rod 34 is fixedly connected to the outer wall of the middle part of the connecting rod 31. A pressing rod 35 corresponding to the button 11 is fixedly connected to the end of the support rod 34 away from the connecting rod 31. A rubber head 351 is fixedly connected to the end of the pressing rod 35 away from the support rod 34. The rubber head 351 increases the friction with the button, improving the accuracy and stability of pressing. The support 2 is equipped with a second spring 26 whose end abuts against the card plate 32. The second spring 26 abuts against the inside of the box cover 4 and between the card plate 32 to enhance the stability of rotation positioning and assist the knob 3 in resetting.

[0027] In addition, such as Figure 1 , Figure 2 and Figure 4 As shown, a knob 3 is fixedly connected to the end of the connecting rod 31 away from the clamping plate 32. The knob 3 is a manually driven component, and the anti-slip groove 36 on its outer wall facilitates operation while wearing gloves, driving the connecting rod 31 to rotate. The outer wall of the knob 3 has multiple anti-slip grooves 36 arranged in a circumferential array. The anti-slip grooves 36 are distributed on the outer wall of the knob 3 to increase the friction between the hand and the knob 3, making it easier to operate the knob 3 while wearing gloves.

[0028] It is worth noting that, such as Figures 2 to 4As shown, the support 2 is equipped with a warning mechanism inside to indicate the rotation angle of the rotating mechanism. The warning mechanism includes a warning slot 33 on the plate 32 corresponding to the button 11. The bottom of the retaining ring 21 has a telescopic groove 22. A first spring 23 is fixedly connected inside the telescopic groove 22. The first spring 23 provides elastic force to the warning spring block 24, causing it to pop out and engage with the warning slot 33. The end of the first spring 23 away from the telescopic groove 22 is fixedly connected to the warning spring block 24. Under the action of the first spring 23, the warning spring block 24 pops out and engages with the warning slot 33 through the spherical locking head 25, emitting a sound to indicate that the rotation angle has been reached. The end of the warning spring block 24 away from the first spring 23 has a spherical locking head 25 that produces a sound after engaging with the warning slot 33. The spherical locking head 25 cooperates with the warning slot 33 to achieve angle positioning and sound indication.

[0029] In this embodiment, when using the coal seam gas treatment equipment, rotating the knob 3 drives the connecting rod 31 and the locking plate 32 to rotate, and the indicator slot 33 on the locking plate 32 rotates with the knob 3. When the locking plate 32 rotates above the corresponding button 11, the indicator spring 24 automatically pops out due to the elastic rebound force of the first spring 23, and its spherical locking head 25 engages with the indicator slot 33, emitting a sound to indicate that the rotation angle is in place. At this time, manually pressing the knob 3 will cause the support rod 34 to drive the pressing rod 35 to press down, and the rubber head 351 will accurately press the corresponding button 11, avoiding accidental touches caused by gloves. At the same time, the second spring 26 abuts against the locking plate 32 to ensure that the knob 3 returns to its original position after being pressed. This also enhances the stability of rotation positioning, and finally, the anti-slip groove 36 makes it easier to operate the knob 3 while wearing gloves, improving the accuracy and efficiency of pressing.

[0030] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
