[0002] The upper corner of the coal face is a high-risk area for gas accumulation. In the existing technology, gas monitoring and extraction equipment are mostly set up independently. It takes a long response time from monitoring and early warning to gas extraction. At the same time, gas monitoring relies on sensors with fixed positions, which is difficult to adapt to the dynamic accumulation of gas in the upper corner. In addition, there is a lack of linkage between monitoring and extraction. When the gas concentration exceeds the standard, the extraction equipment needs to be manually started, which is a delayed response and poses a safety hazard.

[0003] Therefore, this utility model proposes a gas monitoring and extraction device for the upper corner of a coal mining face. Utility Model Content

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Combination Figures 1 to 7 As shown, this utility model proposes a gas monitoring and extraction device for the upper corner of a coal mining face. This device can monitor the gas situation at the coal mining face and extract the gas in a timely manner, thereby reducing the probability of coal mine safety accidents.

[0038] Combination Figure 1 and Figure 2 As shown, the device mainly includes structural components such as a base 1, a pumping pump 22, a gas storage cylinder 21, a gas transmission pipeline 23, a hydraulic cylinder 3, and a sensor integration box 5.

[0039] Combination Figure 5 As shown, a gas extraction pump 22 and a gas storage cylinder 21 are installed on the top of the base 1. The inlet of the gas extraction pump 22 is connected to one end of the gas transmission pipeline 23, and the outlet of the gas extraction pump 22 is connected to the gas storage cylinder 21. This device uses the gas extraction pump 22 to provide power to draw the methane gas from the upper corner of the coal mining face into the gas storage cylinder 21 through the gas transmission pipeline 23, thus realizing the centralized collection and treatment of methane gas.

[0040] Combination Figure 5 As shown, an air intake hood 24 is provided at the other end of the gas pipeline 23. The outer contour of the air intake hood 24 is square and trumpet-shaped. This design can expand the air intake area and improve the gas extraction efficiency, so that the device can more effectively collect the gas accumulated in the upper corner and ensure the comprehensiveness and accuracy of the extraction.

[0041] Combination Figure 3 and Figure 4 As shown, the hydraulic cylinder 3 is vertically mounted on the top of the base 1. The cylinder body end of the hydraulic cylinder 3 is fixedly connected to the base 1, and the telescopic end of the hydraulic cylinder 3 is fixedly connected to the top plate 31. The sensor integration box 5 is mounted above the top plate 31. The hydraulic cylinder 3 can drive the sensor integration box 5 to move longitudinally.

[0042] This invention utilizes a hydraulic cylinder 3 to power the sensor integration box 5, enabling it to move flexibly vertically and thus achieve real-time monitoring of gas concentrations at different heights. This design allows the device to adapt to the dynamic accumulation of gas in the upper corner of the coal face, improving the targeting and accuracy of monitoring. The sensor integration box 5 can be adjusted in height according to actual needs to accommodate coal faces at different heights, ensuring the accuracy and comprehensiveness of gas monitoring.

[0043] Combination Figure 6 and Figure 7 As shown, an angle adjustment mechanism 4 is configured between the sensor integration box 5 and the top plate 31. The angle adjustment mechanism 4 mainly includes structural components such as a first drive motor 41, a drive gear 42, a driven gear 43, a rotating shaft 44, and a mounting plate 45.

[0044] The cylinder end of the first drive motor 41 is fixedly connected to the top plate 31. The output end of the first drive motor 41 is fixedly connected to the middle position of the drive gear 42. The drive gear 42 meshes with the driven gear 43. The middle position of the driven gear 43 is connected to the rotating shaft 44, which is vertically arranged. The bottom end of the rotating shaft 44 is connected to the top plate 31 through a bearing. The top end of the rotating shaft 44 is provided with a mounting plate 45, and the top of the mounting plate 45 is provided with a sensor integration box 5. The first drive motor 41 drives the drive gear 42 to rotate, which in turn drives the driven gear 43 to rotate. The driven gear 43 then drives the rotating shaft 44 to rotate, which in turn drives the mounting plate 45 and the sensor integration box 5 to rotate around the axis of the rotating shaft 44, thereby achieving angle adjustment of the sensor integration box 5. This design allows the sensor integration box 5 to adjust the monitoring angle according to different situations, improving the flexibility and accuracy of monitoring.

[0045] By incorporating the angle adjustment mechanism 4, this device can acquire more comprehensive and accurate information on gas distribution when monitoring gas concentration. The sensor integration box 5 can be flexibly adjusted in both vertical and horizontal directions, ensuring full coverage of the gas accumulation area in the upper corner of the coal mining face, thus improving the efficiency and accuracy of gas monitoring.

[0046] It should also be noted that the sensor integration box 5 is equipped with a gas concentration sensor, a temperature sensor, and a flow sensor, which can monitor key parameters such as gas concentration, temperature, and flow rate in real time, providing strong data support for safe production in the mine.

[0047] Combination Figures 1 to 4As shown, a display screen 7 is also installed on the top of the base 1. This display screen 7 can display data such as gas concentration, temperature, and flow rate monitored by the sensor integration box 5 in real time, allowing staff to intuitively understand the gas situation in the upper corner of the coal mining face and take appropriate safety measures in a timely manner. In addition, the display screen 7 can also display the working status of the device, such as the operation status of the extraction pump 22 and the full / empty status of the gas storage cylinder 21, providing convenience for the maintenance and management of the device.

[0048] The base 1 is also equipped with an audible and visual alarm. When the gas concentration exceeds the standard or the device malfunctions, the audible and visual alarm can issue an audible and visual alarm signal to promptly remind the staff to pay attention and ensure the safe production of the mine.

[0049] Meanwhile, an overflow sensor is installed inside the gas cylinder 21 to monitor the amount of methane gas inside in real time. When the amount of methane gas reaches a preset overflow threshold, the overflow sensor will send a signal, which will control the extraction pump 22 to stop working via the controller 6, preventing methane gas from overflowing and ensuring the safe operation of the device. Simultaneously, after receiving the signal from the overflow sensor, the controller 6 can also trigger an audible and visual alarm to remind operators to handle the methane gas in the gas cylinder 21 in a timely manner, further enhancing the safety performance of the device.

[0050] Combination Figure 3 and Figure 4 As shown, this utility model also includes a controller 6, wherein the first drive motor 41, sensor integration box 5, hydraulic cylinder 3, audible and visual alarm, overflow sensor, and control terminal of extraction pump 22 are all connected to the controller 6 via signal cables. The controller 6 can intelligently control each component to achieve automated monitoring and extraction. When the sensor integration box 5 detects that the gas concentration exceeds the standard, the controller 6 can respond quickly, start the extraction pump 22 to extract the gas, and simultaneously display the gas concentration information on the display screen 7, allowing staff to understand the gas situation in real time. Furthermore, if the gas in the gas storage cylinder 21 reaches an overflow state, the overflow sensor will send a signal to the controller 6, which will then control the audible and visual alarm to sound an alarm, reminding staff to handle the situation promptly and ensuring the safe operation of the device.

[0051] Combination Figure 1 and Figure 2 As shown, rollers 11 are provided at the corners of the base 1, and each roller 11 is equipped with a second drive motor 12. The output end of the second drive motor 12 is fixedly connected to the middle position of the roller 11.

[0052] The second drive motor 12 drives the rollers 11 to rotate, facilitating easy movement of the device and allowing it to adapt flexibly to different working environments, thus improving its applicability and convenience. Simultaneously, a push handle 13 is provided on the base 1, further facilitating the movement and operation of the device by staff, making it more user-friendly. The rollers 11 and push handle on the base 1 facilitate the movement and handling of the device, enhancing its flexibility and practicality.

[0053] Combination Figures 1 to 7 As shown, this utility model proposes a gas monitoring and extraction device for the upper corner of a coal mining face. This device, through the installation of a hydraulic cylinder 3 and an angle adjustment mechanism 4, can flexibly adjust the monitoring height and angle of the sensor in both vertical and horizontal directions, enabling more comprehensive and accurate acquisition of gas distribution information and ensuring the accuracy and comprehensiveness of monitoring. This utility model device achieves timely gas extraction through the extraction pump 22, effectively avoiding safety hazards caused by gas accumulation. Simultaneously, the device possesses high flexibility and intelligence. Its design fully considers the actual conditions of the coal mining face, realizing real-time monitoring and intelligent extraction of gas concentration. During coal mining, when the sensor integration box 5 detects that the gas concentration exceeds the standard, the controller 6 immediately starts the extraction pump 22 to extract the gas and displays the gas concentration information on the display screen 7, facilitating real-time monitoring of the gas situation by staff. Simultaneously, if the gas in the gas storage cylinder 21 reaches overflow, the overflow sensor sends a signal to the controller 6, which then controls the audible and visual alarm to sound, reminding staff to promptly handle the gas in the gas storage cylinder 21 to prevent gas overflow and potential safety hazards. In summary, this gas monitoring and extraction device at the upper corner of the coal face is highly intelligent, flexible, and practical. It can effectively improve the accuracy of gas monitoring and extraction efficiency, ensure safe mine production, and reduce accident risks. The application of this device will provide strong technical support for safe coal mine production and promote the sustainable development of the coal mining industry.
