Description

Technical Field

[0001] This utility model relates to the field of coal mine safety technology, specifically to a blind-spot-free linkage fire extinguishing device for main inclined shafts. Background Technology

[0002] A coal mine main inclined shaft typically refers to the main vertical tunnel in a coal mine that connects the surface and underground areas. This inclined tunnel is used for transporting coal and related materials (such as personnel and equipment), as well as providing ventilation and escape routes. They play a crucial role in connecting surface and underground work areas, allowing miners and equipment to move freely within and outside the mine. Main inclined shafts are also used for drainage, ventilation, and other important mining functions.

[0003] The automatic fire prevention and extinguishing system in the main inclined shaft of a coal mine mainly consists of a controller, sensors, water pumps, and nozzles. When the temperature, smoke, or flames inside the inclined shaft exceed the preset standard, the sensors will automatically send a signal to the controller. The controller will then control the water pump to spray water into the inclined shaft based on the received signal, quickly extinguishing the fire.

[0004] Safety must be ensured in the main inclined shaft of a coal mine, so fire prevention devices need to be installed in the tunnel. However, fire prevention devices are usually installed in a limited location and cannot be moved as needed, which can easily create blind spots. This makes it difficult to detect fires in the main inclined shaft in time, leading to accidents. Utility Model Content

[0005] The purpose of this utility model is to provide a blind-spot-free linkage fire extinguishing device for main inclined shafts. This device facilitates fire monitoring at different locations within the main inclined shaft of a coal mine, reduces blind spots, improves safety within the main inclined shaft, and facilitates fire extinguishing. It addresses the problem that while fire prevention devices are typically installed in fixed locations and cannot be moved as needed, this can create blind spots, preventing timely detection of fires within the main inclined shaft and potentially leading to accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a main inclined shaft blind-spot-free linkage fire extinguishing device, comprising a pipe, a mounting plate, a bolt one, a threaded ring, a bolt two, and a rotating plate. Mounting frames are fixed to the upper and lower ends of one side of the mounting plate. An electric rail is mounted on the upper surface of the mounting plate, and a rail frame is movably connected to the electric rail. A movable plate is fixed to the upper surface of the rail frame. A flame monitoring device is mounted on the upper end of one side of the movable plate. A bracket is fixed to the other side of the mounting plate. A groove is formed on the upper surface of the bracket. A rotating shaft is rotatably connected to the front and rear ends of the inner wall of the groove. The rotating shaft is fixed to the rotating plate. A semi-circular ring is fixed to one side of the rotating plate, and a limit plate is fixed to one side of the semi-circular ring. The semi-circular ring is sleeved with the pipe, and a nozzle is mounted on one side of the outer wall of the pipe.

[0007] Preferably, the mounting bracket has a threaded hole on one side, and a bolt passes through the threaded hole on one side and is threaded together. The bolt also extends into the side wall of the main inclined shaft of the coal mine. This insertion of the bolt through the threaded hole into the side wall of the main inclined shaft facilitates the installation and disassembly of the entire device.

[0008] Preferably, a control switch box is fixed to the front end of the movable plate, and a display screen and buttons are sequentially installed from top to bottom on the front end of the control switch box. The control switch box can control the movement of the rail frame on the electric rail, and can also control the start and stop of the flame monitoring device.

[0009] Preferably, the movable plate has an annular threaded groove on one side, and a threaded ring extends into the annular threaded groove and is threadedly connected. A dustproof net is fixed to one side of the threaded ring. The threaded connection through the threaded ring extending into the annular threaded groove facilitates the installation and removal of the dustproof net, which provides dust protection for the flame monitoring device.

[0010] Preferably, the upper surface of the limiting plate has a through hole, the bottom end of the second bolt passes through the through hole in the limiting plate, and the bottom end of the second bolt passes through the nut and is threaded together. By using the second bolt to pass through the through hole in the limiting plate, the two semicircular rings can be confined, facilitating the installation and disassembly of the pipeline.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model uses a movable rail frame connected to an electric rail. A movable plate is fixed on the upper surface of the rail frame. A flame monitoring device is installed on the upper end of one side of the movable plate, and a bracket is fixed on the other side of the mounting plate. A groove is opened on the upper surface of the bracket. The front and rear ends of the inner wall of the groove are rotatably connected to a rotating shaft, which is fixed to the rotating plate. A semi-circular ring is fixed on one side of the rotating plate, and a limit plate is fixed on one side of the semi-circular ring. The semi-circular ring is sleeved with a pipe, and a nozzle is installed on one side of the outer wall of the pipe. When fire prevention and extinguishing are required in the main inclined shaft of a coal mine, the mounting frame is installed against the side wall of the main inclined shaft of the coal mine. The movable plate moves, and the flame monitoring device can move as needed. When a fire is detected, water is introduced into the pipe, and the nozzle sprays the water out. This achieves convenient fire prevention monitoring at different locations in the main inclined shaft of the coal mine, reduces blind spots, improves the safety of the main inclined shaft of the coal mine, and facilitates fire extinguishing.

[0022] An electric rail 7 is mounted on the upper surface of the mounting plate 6. A rail frame 9 is movably connected to the electric rail 7. A movable plate 4 is fixed to the upper surface of the rail frame 9. A control switch box 3 is fixed to the front end of the movable plate 4. A display screen and buttons are sequentially fitted into the front end of the control switch box 3 from top to bottom. The control switch box 3 can control the movement of the rail frame 9 on the electric rail 7 and can also control the start and stop of the flame monitoring device 12. The flame monitoring device 12 is mounted on the upper end of one side of the movable plate 4. An annular threaded groove 11 is opened on one side of the movable plate 4.

The semi-circular ring 17 is sleeved with the pipe 2. A nozzle 1 is installed on one side of the outer wall of the pipe 2.

[0024] When fire prevention and extinguishing are required in the main inclined shaft of a coal mine, the mounting frame 5 is fitted to a suitable height against the side wall of the main inclined shaft. Bolt 8 is then installed inside the side wall of the main inclined shaft through the threaded hole 10. Pipe 2 passes through the semi-circular ring 17, and the bottom end of bolt 2 15 passes through the through hole in the limiting plate 16. A nut is also threaded through the bottom end of bolt 2 15. The control switch box 3 is operated, causing the rail frame 9 to move on the electric rail 7. Simultaneously, the flame monitoring device 12 can be moved as needed. The flame monitoring device 12 can monitor for fires at different locations within the main inclined shaft. Upon detecting a fire, water is introduced into pipe 2, and nozzle 1 sprays water to extinguish the fire. This achieves convenient fire prevention monitoring at different locations within the main inclined shaft, reduces blind spots, improves safety within the main inclined shaft, and facilitates fire extinguishing.
