Description

Technical Field

[0001] This utility model relates to the field of underground gas monitoring technology in coal mines, specifically a mobile gas bundle tube sampling and monitoring device for underground coal mines. Background Technology

[0002] Monitoring and early forecasting of spontaneous combustion fires in coal seams are fundamental to coal mine fire prevention, forecasting, and control, and are crucial for mine fire prevention and suppression. Accurate and timely early forecasting of spontaneous combustion gases in underground coal mines allows for timely, accurate, and effective preventative measures to avoid such accidents.

[0003] Most coal seam spontaneous combustion fire prediction methods employ ground-based fixed gas tube sampling and monitoring. This involves pre-laying the tube from the ground into goaf or confined spaces inaccessible to personnel underground, and then using a ground vacuum pump to extract gas samples for monitoring. However, ground-based fixed tube monitoring systems suffer from long pipelines and time-consuming sampling and measurement processes. Furthermore, the complex underground mining environment, with its obstacles and difficulty in moving quickly to different sampling points, negatively impacts monitoring efficiency.

[0004] In existing equipment, the connection between the sampling and detection instrument and the bracket is not convenient or reliable enough. During transportation or use, it is easy for it to loosen or even fall off, which increases the probability of equipment failure and maintenance costs. In addition, the overall size of the device is large, occupies a lot of space, and is not convenient to transport and store, which reduces work efficiency and increases management costs. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a mobile gas bundle tube sampling and monitoring device for underground coal mines, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a mobile gas bundle tube sampling and monitoring device for underground coal mines, including a sampling detector, a storage box, and a movable support located below the sampling detector. An extension frame is slidably installed on the side of the movable support away from the sampling detector. A fixed seat is fixedly installed on the end of the movable support near the sampling detector. A connecting seat is fixedly installed on the end of the fixed seat away from the movable support. An installation groove is provided in the center of the end of the connecting seat near the sampling detector. A locking component is fixedly installed on the outer surface of the connecting seat. A guide block is fixedly installed on the end of the sampling detector near the movable support. A limit hole is provided on one side of the outer surface of the guide block. A top plate is hinged to the top of the storage box. Adaptor groove one, adapter groove two, and adapter groove three are provided inside the storage box near the top plate.

[0007] Preferably, the movable support is provided with three sets of legs arranged in a triangular pattern, and the extension frame is provided with the same three sets. All three sets of extension frames and the movable support are slidably connected, and a pressing block is threadedly connected to the outer surface of the movable support near the extension frame.

[0008] The above technical solution features a movable support with three sets of triangularly distributed legs, which provides strong stability. All three sets of extension frames are slidably connected to the movable support, and a compression block is threaded onto the outer surface of the movable support near the extension frame. This facilitates rapid assembly of the extension frame and the movable support. Furthermore, by adjusting the length of the extension frame, it can adapt to the complex and uneven ground conditions in coal mines. The compression block enables rapid fixing and adjustment of the extension frame, enhancing the stability and flexibility of the device placement.

[0009] Preferably, the cross-section of the guide block is the same as the cross-section of the mounting groove, and the guide block and the mounting groove are connected by an insertion joint.

[0010] The above technical solution, through the design of the guide block and the mounting groove for plug-in installation, enables the rapid alignment and installation of the sampling detector and the connector, reducing installation errors. The plug-in installation method also facilitates the rapid disassembly of the sampling detector, making it convenient for maintenance, replacement or transportation of the sampling detector.

[0011] Preferably, the locking assembly includes a fixing block, a pull block is provided on the side of the fixing block away from the connecting seat, a limit rod is fixedly installed on the end of the pull block near the fixing block, a limit plate is fixedly installed on the outer surface of the limit rod away from the fixing block, and a return spring is provided between the limit plate and the fixing block.

[0012] The above technical solution incorporates a locking component, which enhances the connection strength between the sampling detector and the connector, preventing the sampling detector from falling off during testing and thus avoiding damage to the detector, thereby improving the overall safety of the device.

[0013] Preferably, the cross-section of the limiting rod is the same as the cross-section of the limiting hole, and the limiting rod can be inserted into the limiting hole.

[0014] With the above technical solution, the cross-section of the limiting rod is the same as that of the limiting hole, and the limiting rod can be inserted into the limiting hole. When installing the sampling detector, the operator can manually pull the pull block to disengage the limiting rod from the mounting slot. Then, the sampling detector is installed in the mounting slot. The operator releases the pull block, and the elasticity of the return spring causes the limiting rod to automatically reset and engage with the limiting hole, preventing the sampling detector from detaching from the connecting seat and ensuring the stability of the sampling detector during operation. When disassembly is required, the operator only needs to pull the pull block until it separates from the limiting hole to achieve quick disassembly of the sampling detector. The operation is simple and highly practical.

[0015] Preferably, a latch is fixedly installed on one side of the storage box, and a buckle is fixedly installed on one side of the top plate, wherein the latch and the buckle are mating components.

[0016] The above technical solution uses latches and buckles as cooperating components to securely lock the top plate to the storage box, effectively preventing the top plate from opening accidentally during the transportation of testing equipment. This protects the sampling and testing instruments, movable supports, and extension racks stored inside the box from collisions during handling or storage.

[0017] Preferably, the first adapter slot is adapted to the sampling detector, the second adapter slot is adapted to the movable bracket, and the third adapter slot is adapted to the extension frame.

[0018] The above technical solution, by setting adapter slot one to be compatible with the sampling and detection instrument, adapter slot two to be compatible with the movable bracket, and adapter slot three to be compatible with the extension frame, facilitates the overall storage of the device, saves storage space, and effectively prevents collisions between components in the storage box during transportation, thereby extending the service life of the device.

[0019] Compared with the prior art, this utility model provides a mobile gas bundle tube sampling and monitoring device for underground coal mines, which has the following advantages:

[0020] 1. The mobile gas bundle tube sampling and monitoring device for underground coal mines, through the design of the guide block and the installation groove for plug-in installation, can realize the quick alignment and installation of the sampling detector and the connecting seat, reduce installation errors, and the plug-in installation method also facilitates the quick disassembly of the sampling detector, making it convenient for maintenance, replacement or transportation of the sampling detector.

[0021] 2. The mobile gas bundle tube sampling and monitoring device for underground coal mines is designed with three adapter slots: one for the sampling and detection instrument, two for the movable support, and three for the extension frame. This design facilitates the overall storage of the device, saves storage space, and effectively prevents collisions between components in the storage box during transportation, thereby extending the device's service life.

[0022] 3. This mobile gas bundle tube sampling and monitoring device for underground coal mines features a limiting rod with the same cross-section as the limiting hole, allowing the limiting rod to engage within the hole. During installation, workers can manually pull the lever to detach the limiting rod from the mounting slot, then install the sampling device. Releasing the lever allows the limiting rod to automatically reset and engage with the limiting hole via the elasticity of the return spring, preventing the sampling device from detaching from the connecting seat and ensuring its stability during operation. For disassembly, workers simply pull the lever until it separates from the limiting hole, enabling quick disassembly of the sampling device. The device is simple to operate and highly practical.

[0033] 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.

[0034] Example 1: As Figure 1-9As shown, the present invention provides a mobile gas bundle tube sampling and monitoring device for underground coal mines, including a sampling detector 1, a storage box 11, and a movable support 2 located below the sampling detector 1. An extension frame 3 is slidably installed on the side of the movable support 2 away from the sampling detector 1. A fixed seat 5 is fixedly installed on the end of the movable support 2 near the sampling detector 1. A connecting seat 6 is fixedly installed on the end of the fixed seat 5 away from the movable support 2. An installation groove 7 is provided in the center of the end of the connecting seat 6 near the sampling detector 1. A locking component 8 is fixedly installed on the outer surface of the connecting seat 6. A guide block 9 is fixedly installed on the end of the sampling detector 1 near the movable support 2. A limit hole 10 is provided on one side of the outer surface of the guide block 9. A top plate 12 is hinged to the top of the storage box 11. An adapter groove 15, an adapter groove 2 16, and an adapter groove 3 17 are provided inside the storage box 11 near the end of the top plate 12.

[0035] Specifically, the movable support 2 is equipped with three sets of triangularly distributed legs, and the extension frame 3 is equipped with the same three sets. All three sets of extension frames 3 are slidably connected to the movable support 2. A pressing block 4 is threadedly connected to the outer surface of the movable support 2 near the extension frame 3. The advantages are that the three sets of triangularly distributed legs on the movable support 2 provide strong stability, and the slidable connection of the three sets of extension frames 3 to the movable support 2, along with the pressing block 4 threadedly connected to the outer surface of the movable support 2 near the extension frame 3, facilitates rapid assembly of the extension frame 3 and the movable support 2. Furthermore, by adjusting the length of the extension frame 3, it can adapt to the complex and uneven ground conditions underground in coal mines, and the pressing block 4 enables rapid fixing and adjustment of the extension frame 3, enhancing the stability and flexibility of the device placement.

[0036] Specifically, the cross-section of the guide block 9 is the same as the cross-section of the mounting groove 7, and the guide block 9 and the mounting groove 7 are connected by a plug-in joint. The advantage is that the plug-in joint design of the guide block 9 and the mounting groove 7 allows for quick alignment and installation of the sampling detector 1 and the connecting seat 6, reducing installation errors. Furthermore, the plug-in joint installation method facilitates the quick disassembly of the sampling detector 1, making it easier to maintain, replace, or transport the sampling detector 1.

[0037] Specifically, the locking assembly 8 includes a fixing block 801, a pull block 802 on the side of the fixing block 801 away from the connecting seat 6, a limit rod 803 fixedly installed at the end of the pull block 802 near the fixing block 801, a limit plate 804 fixedly installed on the outer surface of the limit rod 803 away from the fixing block 801, and a return spring 805 between the limit plate 804 and the fixing block 801. The advantage is that the locking assembly 8 improves the connection strength between the sampling detector 1 and the connecting seat 6, preventing the sampling detector 1 from falling off during testing and thus preventing damage to the sampling detector 1, thereby improving the overall safety of the device.

[0038] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, the cross-section of the limiting rod 803 is the same as the cross-section of the limiting hole 10, and the limiting rod 803 can be inserted into the limiting hole 10. The advantage is that, because the cross-section of the limiting rod 803 is the same as the cross-section of the limiting hole 10, and the limiting rod 803 can be inserted into the limiting hole 10, when installing the sampling detector 1, the operator can manually pull the pull block 802 to disengage the limiting rod 803 from the mounting groove 7. Then, the sampling detector 1 is installed in the mounting groove 7. The operator then releases the pull block 802, and the elastic action of the return spring 805 causes the limiting rod 803 to automatically reset and engage with the limiting hole 10, preventing the sampling detector 1 from detaching from the connecting seat 6 and ensuring the stability of the sampling detector 1 during operation. When disassembly is required, the operator only needs to pull the pull block 802 until it separates from the limiting hole 10 to achieve quick disassembly of the sampling detector 1. The operation is simple and highly practical.

[0040] Specifically, a latch 13 is fixedly installed on one side of the storage box 11, and a latch 14 is fixedly installed on one side of the top plate 12. The latch 13 and the latch 14 are mating components. The advantage is that by using the latch 13 and the latch 14 as mating components, the top plate 12 can be firmly locked onto the storage box 11, which can effectively prevent the top plate 12 from being accidentally opened during the transportation of testing equipment, and protect the sampling and testing instrument 1, movable bracket 2, and extension frame 3 stored in the box from collisions during handling or storage.

[0041] Specifically, adapter slot 15 is adapted to the sampling and detection instrument 1, adapter slot 2 16 is adapted to the movable support 2, and adapter slot 3 17 is adapted to the extension frame 3. The advantage is that by setting adapter slot 15 to adapt to the sampling and detection instrument 1, adapter slot 2 16 to adapt to the movable support 2, and adapter slot 3 17 to adapt to the extension frame 3, the device can be easily stored, saving storage space. It also effectively prevents collisions between components within the storage box 11 during transportation, thereby extending the device's service life.

[0042] Working Principle: In use, first open the storage box 11 and remove the sampling detector 1, movable support 2, and extension frame 3. The movable support 2 has three sets of triangularly distributed legs, providing strong stability. All three extension frames 3 are slidably connected to the movable support 2. A pressing block 4 is threaded onto the outer surface of the movable support 2 near the extension frame 3, facilitating quick assembly of the extension frame 3 with the movable support 2. Adjusting the length of the extension frame 3 allows it to adapt to the complex and uneven ground conditions in coal mines. The pressing block 4 enables quick fixing and adjustment of the extension frame 3, enhancing the stability and flexibility of the device placement. Subsequently, the guide block 9 and mounting groove 7 are designed for plug-in installation, allowing for quick alignment and installation of the sampling detector 1 and connecting seat 6, reducing installation errors. The plug-in installation method also facilitates quick disassembly of the sampling detector 1, making maintenance, replacement, or transportation convenient. The limit rod 803's cross-section... The limiting holes 10 have the same cross-section, and the limiting rod 803 can be inserted into the limiting hole 10. When installing the sampling detector 1, the operator can manually pull the pull block 802 to disengage the limiting rod 803 from the mounting groove 7. Then, the sampling detector 1 is installed in the mounting groove 7. The operator releases the pull block 802, and the elastic action of the return spring 805 causes the limiting rod 803 to automatically reset and engage in the limiting hole 10, preventing the sampling detector 1 from disengaging from the connecting seat 6 and ensuring the stability of the sampling detector 1 during operation. Qualitatively, when disassembly is required, the operator only needs to pull the pull block 802 until it separates from the limit hole 10 to quickly disassemble the sampling detector 1. The operation is simple and highly practical. Finally, by setting the adapter slot 15 to be compatible with the sampling detector 1, the adapter slot 2 to be compatible with the movable bracket 2, and the adapter slot 3 to be compatible with the extension frame 3, the overall storage of the device is facilitated, saving storage space and effectively preventing collisions of various components in the storage box 11 during transportation, thereby extending the service life of the device.

[0043] 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.
