Description

Technical Field

[0001] This utility model relates to the field of coal mine gas concentration detection technology, and in particular to a coal mine gas concentration detection and inspection device. Background Technology

[0002] Coal mine gas concentration detection is a crucial aspect of coal mine safety production. It aims to monitor the underground gas (mainly methane) content in real time to prevent safety accidents such as explosions caused by excessively high gas concentrations.

[0003] Existing methods for detecting methane concentration inside coal mine roadways typically employ fixed-point detection. While some mobile inspection equipment can move within the roadways, the sampling points remain unchanged. However, the varying content of different substances in methane causes variations in the methane's position in the air, leading to errors and insufficient accuracy in the sampling process of existing methane concentration detection equipment.

[0004] Therefore, a coal mine gas concentration detection and inspection device has been developed that can sample air in different spatial locations within coal mine roadways, increasing the sampling range and improving the accuracy of coal mine gas prevention and control. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a coal mine gas concentration detection and inspection device capable of sampling air at different spatial locations within coal mine roadways, thereby increasing the sampling range and improving the accuracy of coal mine gas prevention and control.

[0006] The technical solution is as follows: A coal mine gas concentration detection and inspection device, comprising a slide rail, a connector, a detector, an air inlet pipe, a signal transmission component, and an auxiliary mechanism. The slide rail is installed on the roof of the coal mine roadway. The connector is slidably connected to the lower part of the slide rail and is driven by a traction device. The detector is connected to the bottom of the connector and is electrically connected to an external backend system. The signal transmission component is connected to the lower side of the detector and is also electrically connected to the external backend system. The air inlet pipe is connected to the detector and is connected to the auxiliary mechanism fixed on the detector. The auxiliary mechanism enables air sampling at different spatial locations.

[0007] Indicator lights are provided on both sides of the detector.

[0008] A camera is fixed to the detector below the air intake pipe.

[0009] The auxiliary mechanism includes a fixing component, an electric push rod, a connecting pipe, an electric valve, an air intake head, and a connecting plate. The fixing component is connected to the lower part of the detector, and the electric push rod is connected to the fixing component. The connecting plate is connected to the telescopic end of the electric push rod, and the air intake head is connected to the connecting plate. The connecting pipe is connected to the lower part of the air inlet pipe, and an electric valve is provided at the top of the connecting pipe. The top of the air intake head is connected to the connecting pipe. The telescopic end of the electric push rod controls the movement of the connecting plate, and the movement of the connecting plate drives the air intake head to move. The position of the air intake head in the coal mine roadway changes, enabling it to sample the air in different spatial locations within the coal mine roadway and guide the sample into the connecting pipe. The sample is then guided into the air inlet pipe through the connecting pipe for gas concentration detection by the detector.

[0010] The connecting pipe is a telescopic and elastic structure.

[0011] The detector is equipped with a temperature detection mechanism, which includes a mounting plate and a temperature sensor. Mounting plates are provided on both sides of the detector, and temperature sensors are connected to the bottom of each mounting plate. The temperature sensors are electrically connected to the detector. When the detector moves, the mounting plates move, and the mounting plates move the temperature sensors. The detector detects the temperature inside the coal mine roadway through the temperature sensors.

[0012] The beneficial effects of this utility model are as follows: This utility model controls the movement of the connecting plate by means of the extension and retraction end of the electric push rod. The movement of the connecting plate drives the air suction head to move. The operation of changing the position of the air suction head in the coal mine roadway space enables air sampling in different spatial locations in the coal mine roadway, increasing the sampling range and improving the accuracy of coal mine prevention and control.

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] A coal mine gas concentration detection and inspection device, such as Figure 1 and Figure 2 As shown, it includes a slide rail 1, a connector 2, a detector 3, an indicator light 4, a camera 5, an air intake pipe 6, a signal transmission component 7, and an auxiliary mechanism 8. The lower part of the slide rail 1 is slidably connected to the connector 2, and the bottom of the connector 2 is connected to the detector 3. The detector 3 is electrically connected to an external backend system. The lower side of the detector 3 is connected to the signal transmission component 7, which is also electrically connected to the external backend system. The detector 3 is connected to the air intake pipe 6, which is connected to the auxiliary mechanism 8 fixed on the detector, enabling air sampling in different spatial locations. Indicator lights 4 are provided on both sides of the detector 3, and a camera 5 is fixed on the detector 3 below the air intake pipe 6.

[0019] like Figure 1 and Figure 3 As shown, the auxiliary mechanism 8 includes a fixing component 81, an electric push rod 82, a connecting pipe 83, an electric valve 84, an air intake head 85, and a connecting plate 86. The fixing component 81 is connected to the lower part of the detector 3, and the electric push rod 82 is connected to the fixing component 81. The connecting plate 86 is connected to the telescopic end of the electric push rod 82, and the air intake head 85 is connected to the connecting plate 86. The connecting pipe 83 is connected to the lower part of the air inlet pipe 6, and the electric valve 84 is provided at the top of the connecting pipe 83. The top of the air intake head 85 is connected to the connecting pipe 83. The connecting pipe 83 is a telescopic elastic structure. The telescopic end of the electric push rod 82 controls the movement of the connecting plate 86. The movement of the connecting plate 86 drives the air intake head 85 to move. The position of the air intake head 85 in the coal mine roadway changes, which can sample the air in different spatial locations in the coal mine roadway and introduce the sample into the connecting pipe 83. The sample is then introduced into the air inlet pipe 6 through the connecting pipe 83 for gas concentration detection by the detector.

[0020] like Figure 1 and Figure 3 As shown, the detector 3 is equipped with a temperature detection mechanism 9, which includes a mounting plate 91 and a temperature sensor 92. Mounting plates 91 are provided on both sides of the front of the detector 3. Temperature sensors 92 are connected to the bottom of the mounting plates 91. The temperature sensors 92 are electrically connected to the detector 3. When the detector 3 moves, the mounting plates 91 move, and the mounting plates 91 move the temperature sensors 92. The detector 3 detects the temperature in the coal mine roadway through the temperature sensors 92.

[0021] In use, the slide rail 1 is first installed on the roof of the coal mine roadway. The connecting piece 2 is moved by a traction device. The movement of the connecting piece 2 moves the detector 3, which in turn moves all components on the detector 3. The detector 3 is remotely controlled by a backend system. When the detector 3 starts, the air inlet pipe 6 generates negative pressure, which, through the connecting pipe 83 and the suction head 85, draws air from inside the coal mine roadway into the detector 3. When the detector 3 detects that the methane concentration in the coal mine roadway exceeds a preset value, the indicator light 4 illuminates, and the data is transmitted to the backend system via the signal transmission component 7. The system issues an alarm. During routine air sampling operations, the telescopic end of the electric push rod 82 controls the movement of the connecting plate 86. The movement of the connecting plate 86 causes the air intake head 85 to move, changing its position within the coal mine roadway. This allows for air sampling at different locations within the roadway, and the samples are then introduced into the connecting pipe 83. Through the connecting pipe 83, the samples are introduced into the air inlet pipe 6, where the detector 3 detects the gas concentration. The movement of the detector 3 also causes the mounting plate 91 to move, which in turn causes the temperature sensor 92 to move. The detector 3 then uses the temperature sensor 92 to detect the temperature within the coal mine roadway.

[0022] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
