Description

Technical Field

[0001] This invention relates to the technical field of lighting devices, specifically to a mine compressed air driven explosion-proof LED tunnel lighting device. Background Technology

[0002] In mining operations, tunnel lighting is a crucial element in ensuring both safety and operational efficiency. Mine tunnel lighting devices must be able to withstand the harsh environment of high humidity, high dust levels, susceptibility to impact, and the potential presence of flammable and explosive gases such as methane underground for extended periods. They must also possess stable lighting performance and reliable safety protection capabilities to meet continuous operational needs and mitigate safety risks.

[0003] Currently, most existing mine roadway lighting devices use traditional light sources or ordinary LED light sources. Although they have improved in terms of lighting brightness, they still have significant shortcomings in terms of explosion-proof performance, impact resistance, and emergency adaptability.

[0004] In addition, mining operations face the risk of sudden disasters such as collapses and water inrushes. When a disaster occurs and workers are trapped, the underground ventilation system may fail and oxygen may be gradually depleted. Existing mine lighting devices do not consider emergency oxygen supply functions and cannot provide temporary air supply for trapped personnel, thus missing the golden time for rescue and threatening the lives of trapped personnel.

[0005] In summary, existing mine roadway lighting devices have technical deficiencies in terms of impact resistance, explosion-proof sealing, emergency oxygen supply, installation and maintenance, and pressure regulation, which urgently need to be addressed. They are unable to fully meet the safety operation and emergency support needs of the complex and harsh underground mining environment. Therefore, developing a mine roadway lighting device with efficient explosion-proof performance, reliable impact protection, and emergency oxygen supply functions has become an important research direction in the field of mine safety equipment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a mine compressed air driven explosion-proof LED tunnel lighting device, which has advantages such as high-efficiency explosion-proof performance, reliable impact resistance, and emergency oxygen supply function, thus solving the problems that still exist in terms of impact resistance and emergency adaptability.

[0007] To achieve the aforementioned objectives of high-efficiency explosion-proof performance, reliable impact resistance, and emergency oxygen supply, this invention provides the following technical solution: A mine compressed air driven explosion-proof LED tunnel lighting device, comprising a protective cover, a lamp body movably connected inside the protective cover, a movable tube fixedly sleeved on the lamp body, a rubber ring fixedly sleeved on the movable tube, the rubber ring fitting against the inner wall of the protective cover, an outer ring fixedly installed on the left side of the protective cover, a rubber ring fixedly installed on the right end of the protective cover, a connecting ring fixedly installed on the right end of the rubber ring, a back plate fixedly installed on the right end of the connecting ring, a vertical pipe fixedly connected to the connecting ring, a rotating tube threadedly connected to the vertical pipe, a connecting pipe threadedly connected to the rotating tube, a valve fixedly installed on the connecting pipe, and an air tank fixedly installed at the lower end of the connecting pipe.

[0008] Preferably, a bracket is fixedly installed inside the protective cover, the bracket is fixedly connected to the connecting ring, and the rubber ring is movably sleeved on the bracket.

[0009] Preferably, a semi-circular block is provided below the gas tank, and a placement groove is opened on the upper side of the semi-circular block. Two support rods are fixedly installed on the right side of the semi-circular block, and support tubes are movably sleeved on the two support rods. An installation plate is fixedly installed on the right end of the two support tubes.

[0010] Preferably, a rotating block is movably connected to the left side of the mounting plate via a bearing, and a movable tube is fixedly installed on the left side of the rotating block. A screw is threadedly connected to the movable tube, and the screw is fixedly connected to the semi-circular block.

[0011] Preferably, a bottom tube is fixedly sleeved on the gas tank, an adjusting tube is threadedly sleeved on the bottom tube, several small tubes are fixedly installed on the adjusting tube, and a rotating disc is fixedly sleeved on the rotating tube.

[0012] Preferably, an air pipe is fixedly connected to the protective cover, and two round boxes are fixedly installed on the air pipe. A pressure spring is fixedly installed on the inner rear wall of each of the two round boxes. A moving rod is fixedly installed at the front end of each of the two pressure springs. A moving strip is fixedly installed at the front end of each of the two moving rods. A movable block is fixedly installed on each of the two moving strips. A thin rod is fixedly installed on the rear side of the movable block.

[0013] Preferably, a ring plate is movably sleeved on the thin rod, the ring plate is fixedly connected to the inner wall of the trachea, a baffle is fixedly installed at the rear end of the thin rod, an annular groove is opened on the baffle, a sealing ring is fixedly installed in the annular groove, and the sealing ring is in contact with the ring plate.

[0014] Compared with the prior art, the present invention provides a mine compressed air driven explosion-proof LED tunnel lighting device, which has the following beneficial effects: 1. This mine-use compressed air-driven explosion-proof LED tunnel lighting device allows air to be injected into the protective cover by opening the valve. This allows the lamp body to move to the left. After injecting an appropriate amount of gas, the valve can be closed. When the lamp body is impacted, it will move to the right, compressing the air inside the protective cover. This causes the rubber ring to expand, thus using the air and rubber ring to cushion the lamp body. In addition, when a mine collapse or other disaster occurs and miners are trapped inside, nearby gas cylinders can be disassembled to provide air for the miners and buy time for rescue.

[0015] 2. This mine compressed air driven explosion-proof LED tunnel lighting device can connect the protective cover and the connecting ring through the bracket, thereby supporting the lamp body to prevent shaking and preventing the gas from blocking the rubber ring from expanding.

[0016] 3. This mine compressed air driven explosion-proof LED tunnel lighting device can be installed on the mine wall via a mounting plate. After the air tank is installed, the semi-circular block and the placement groove can support the air tank, thus preventing the air tank from being too heavy and affecting the mine lamp. At the same time, the position of the semi-circular block can be adjusted by rotating the movable tube via a screw and a movable tube.

[0017] 4. This mine compressed air driven explosion-proof LED tunnel lighting device allows users to remove and replace the air tank by rotating the adjusting tube upwards. After the air tank is connected to the vertical pipe, the adjusting tube can be rotated downwards to fit into the placement slot to support the air tank. The rotating disc and small tube allow users to easily rotate the rotating tube and adjusting tube back and forth.

[0018] 5. This mine compressed air driven explosion-proof LED tunnel lighting device uses a mechanism where pressing the movable block backward moves the baffle backward via a thin rod, allowing air inside the protective cover to be expelled through the air pipe. This allows for air release when there is excessive air inside the protective cover. When the movable block is released, the rebound of the pressure spring moves the movable block forward via the moving rod and moving bar, which in turn moves the baffle forward, allowing the sealing ring to fit against the ring plate for sealing.

It should be noted that the terms “front”, “rear”, “left”, “right”, “upper” and “lower”, “bottom surface” and “top surface” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific part, respectively.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-8This invention provides a technical solution: a mine compressed air driven explosion-proof LED tunnel lighting device, comprising a protective cover 1, a lamp body 3 movably connected inside the protective cover 1, a movable tube 35 fixedly sleeved on the lamp body 3, a rubber ring 36 fixedly sleeved on the movable tube 35, the rubber ring 36 fitting against the inner wall of the protective cover 1, an outer ring 2 fixedly installed on the left side of the protective cover 1, a rubber ring 11 fixedly installed on the right end of the protective cover 1, a connecting ring 10 fixedly installed on the right end of the rubber ring 11, a back plate 9 fixedly installed on the right end of the connecting ring 10, a vertical tube 22 fixedly connected to the connecting ring 10, a rotating tube 24 threadedly connected to the vertical tube 22, a connecting tube 25 threadedly connected to the rotating tube 24, and a fixedly installed... A gas cylinder 4 is fixedly installed at the lower end of valve 7 and connecting pipe 25. By opening valve 7, air can be injected into protective cover 1, which can push the lamp body 3 to move to the left. After injecting an appropriate amount of gas, valve 7 can be closed. When the lamp body 3 is impacted, the lamp body 3 will move to the right and compress the air in protective cover 1, which will cause the rubber ring 11 to expand. Thus, the air and rubber ring 11 can be used to cushion the lamp body 3. At the same time, when a mine collapses or other disasters occur, if the workers in the mine are trapped, the nearby gas cylinder 4 can be removed to provide air for the workers and buy time for rescue. A bracket 37 is fixedly installed inside the protective cover 1. The bracket 37 is fixedly connected to the connecting ring 10. A rubber ring 11 is movably sleeved on the bracket 37. The bracket 37 connects the protective cover 1 to the connecting ring 10, thereby supporting the lamp body 3 to prevent shaking and preventing the gas from obstructing the expansion of the rubber ring 11. A semi-circular block 5 is set below the gas tank 4. A placement groove 31 is opened on the upper side of the semi-circular block 5. Two support rods 30 are fixedly installed on the right side of the semi-circular block 5. Support tubes 29 are movably sleeved on the two support rods 30. Mounting plates 6 are fixedly installed on the right ends of the two support tubes 29. A rotating block 34 is movably connected to the left side of the mounting plate 6 through a bearing. A movable tube 33 is fixedly installed on the left side of the rotating block 34. Inside the movable tube 33 A threaded screw 32 is connected to a semi-circular block 5. The screw 32 is fixedly connected to the semi-circular block 5 and can be installed on the mine wall via a mounting plate 6. After installing the gas cylinder 4, the semi-circular block 5 and the placement groove 31 can support the gas cylinder 4, preventing it from being too heavy and affecting the mine lamp. Simultaneously, the position of the semi-circular block 5 can be adjusted by rotating the movable tube 33 via the screw 32 and the movable tube 33. A bottom tube 28 is fixedly sleeved on the gas cylinder 4, and an adjusting tube 27 is threadedly sleeved on the bottom tube 28. Several small tubes 26 are fixedly installed on the adjusting tube 27. A rotating disc 23 is fixedly sleeved on the rotating tube 24. By rotating the adjusting tube 27 upwards, the gas cylinder 4 can be rotated downwards to remove it and replace it with a new gas cylinder 4. After the tank 4 is connected to the vertical pipe 22, the adjusting pipe 27 can be rotated downwards to fit into the placement groove 31 to support the gas tank 4. The rotating disc 23 and the small pipe 26 allow the user to easily rotate the rotating pipe 24 and the adjusting pipe 27 back and forth. The protective cover 1 is fixedly connected to the gas pipe 8, and two round boxes 12 are fixedly installed on the gas pipe 8. Pressure springs 21 are fixedly installed on the inner rear wall of each of the two round boxes 12. Moving rods 13 are fixedly installed at the front end of each of the two pressure springs 21, and moving strips 14 are fixedly installed at the front end of each of the two moving rods 13. Movable blocks 15 are fixedly installed on each of the two moving strips 14, and thin rods 16 are fixedly installed on the rear side of the movable blocks 15. A ring plate 17 is movably sleeved on the thin rod 16, and the ring plate 17 is flush with the inner wall of the gas pipe 8. A fixed connection is made, with a baffle 19 fixedly installed at the rear end of the thin rod 16. An annular groove 18 is provided on the baffle 19, and a sealing ring 20 is fixedly installed in the annular groove 18. The sealing ring 20 fits against the annular plate 17. By pressing the movable block 15 backward, the baffle 19 can be moved backward by the thin rod 16, so that the air in the protective cover 1 can be discharged through the air pipe 8. This allows the air to be discharged when there is too much air in the protective cover 1. When the movable block 15 is released, the rebound of the pressure spring 21 will drive the movable block 15 forward through the moving rod 13 and the moving bar 14, which will drive the baffle 19 forward, so that the sealing ring 20 can fit against the annular plate 17 for sealing.

[0025] In use, the first step is to open valve 7 to inject air into the protective cover 1. This allows the lamp body 3 to move to the left. After injecting an appropriate amount of gas, valve 7 can be closed. When the lamp body 3 is impacted, it will move to the right, compressing the air inside the protective cover 1. This causes the rubber ring 11 to expand, thus using the air and rubber ring 11 to cushion the lamp body 3. In addition, when a mine collapses or other disasters occur, and miners are trapped inside, nearby gas cylinders 4 can be removed to provide air for the miners and buy time for rescue.

[0026] Step 2: The protective cover 1 and the connecting ring 10 can be connected by the bracket 7, thereby supporting the lamp body 3 to prevent shaking, and also preventing the gas from blocking the expansion of the rubber ring 11.

[0027] Step 3: The mounting plate 6 can be installed on the wall of the mine shaft. After the gas cylinder 4 is installed, the semi-circular block 5 and the placement groove 31 can be used to support the gas cylinder 4, thereby preventing the gas cylinder 4 from being too heavy and affecting the mine lamp. At the same time, the position of the semi-circular block 5 can be adjusted by rotating the movable tube 33 through the screw 32 and the movable tube 33.

[0028] Step 4: After rotating the adjusting tube 27 upwards, the gas cylinder 4 can be rotated downwards to remove it and replace it with a new gas cylinder 4. After the gas cylinder 4 is connected to the vertical tube 22, the adjusting tube 27 can be rotated downwards to fit into the placement groove 31 to support the gas cylinder 4. The rotating plate 23 and the small tube 26 allow the user to easily rotate the rotating tube 24 and the adjusting tube 27 back and forth.

[0029] Step 5: By pressing the movable block 15 backward, the baffle 19 can be moved backward by the thin rod 16. This allows the air inside the protective cover 1 to be expelled through the air pipe 8, thus releasing air when there is too much air inside the protective cover 1. When the movable block 15 is released, the rebound of the pressure spring 21 will move the movable block 15 forward through the moving rod 13 and the moving bar 14. This will move the baffle 19 forward, so that the sealing ring 20 can be put into contact with the ring plate 17 for sealing.
