Description

Technical Field

[0001] This utility model relates to the technical field of coal mine safety production equipment, and in particular to a mine-use inflatable firewall. Background Technology

[0002] In coal mining operations, the underground environment is complex and ever-changing. Safety hazards such as gas leaks and fires constantly threaten the lives of miners and the safety of mine production. Therefore, firewalls have become a key facility in the underground safety protection system of coal mines. Traditional mine firewalls are mostly constructed on-site using materials such as bricks, stones, and concrete. These fixed firewalls have many limitations. On the one hand, their construction process is time-consuming and labor-intensive, requiring a large investment of manpower and resources, and in emergency situations, they cannot respond quickly and form an effective protective barrier. On the other hand, fixed firewalls lack flexibility and are difficult to adjust according to changes in the layout and size of mine roadways, significantly reducing their applicability in some special operating areas or narrow roadways.

[0003] With technological advancements, inflatable firewalls have emerged, rapidly deploying inflatable airbags to form isolation barriers and improving emergency response speed to some extent. However, existing inflatable firewalls still present several problems in practical applications. For instance, the airbags are prone to shifting and jamming during deployment and retraction, affecting the firewall's stability and reliability; the airbags deploy slowly, failing to quickly establish effective protection in emergencies; the retraction operation is complex, hindering convenient and efficient control; furthermore, the lack of effective design for rapid inflation and deflation of the airbags in different usage scenarios results in insufficient adaptability. In addition, existing inflatable firewalls often lack real-time monitoring capabilities of the surrounding environment, failing to promptly detect changes in key safety indicators such as temperature and gas concentration, making it difficult to proactively trigger protection mechanisms and posing significant risks to mine safety.

[0004] Therefore, there is an urgent need to develop a new type of inflatable fireproof wall for mining to solve the above-mentioned technical problems and further improve the safety protection level of mines.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0033] Reference Figure 1-6 A mine-use inflatable fireproof wall includes an installation frame 1, an inflatable airbag 21, a hollow roller 2, a hollow shaft 201, an installation box 3, an air pump 31, a conveying pipe 32, a temperature sensor 4, and a gas sensor 41.

[0034] The inner wall of the mounting frame 1 is provided with a mounting groove 11. The hollow shaft 201 is rotatably mounted on the inner walls of both sides of the mounting groove 11. The hollow roller 2 is fixedly mounted on the hollow shaft 201 and connected to the hollow shaft 201. The inflatable airbag 21 is fixed and wound around the hollow roller 2.

[0035] Guide blocks 23 are slidably installed on both sides of the inner wall of the mounting groove 11. The same sealing plate 22 is fixedly installed on the side of the two guide blocks 23 that are close to each other. The end of the inflatable airbag 21 away from the hollow roller 2 is fixedly installed on the top side of the sealing plate 22. Guide rods 231 are fixedly installed on both sides of the inner wall of the mounting groove 11. The two guide rods 231 are arranged parallel to each other and are slidably connected to the corresponding guide blocks 23 respectively. They can provide a guiding effect when the inflatable airbag 21 unfolds and retracts. A flexible sealing gasket that matches the bottom ground position of the mounting frame 1 is fixedly pasted on the bottom side of the sealing plate 22. It can maintain a sealed contact with the bottom ground through the flexible sealing gasket when the sealing plate 22 moves to the lowest point.

[0036] An inflation tube 211, which is arranged in a wound shape, is fixed and connected to the hollow roller 2. The inflation tube 211 extends into the inflation bladder 21 and is fixedly installed with multiple branch tubes 212 for inflating the inflation bladder 21. Multiple elastic ropes 213 connected to the inner wall of the inflation bladder 21 are fixedly installed on the inflation tube 211, which can provide an auxiliary effect when the inflation bladder 21 is unfolded, thereby ensuring that the inflation bladder 21 unfolds smoothly. The inflation tube 211 is arranged in a flat shape, which can increase the contact area with the inner wall of the inflation bladder 21 when the inflation bladder 21 is in the winding state, while reducing the space occupation, thereby ensuring that the inflation bladder 21 is stably wound onto the hollow roller 2.

[0037] A motor 202 is fixedly installed on one side of the mounting frame 1. The motor 202 is a mining motor. The output shaft of the motor 202 extends into the hollow shaft 201 and is fixedly fitted with a ratchet 203. A pawl 204 adapted to the ratchet 203 is hinged to the inner wall of the hollow shaft 201. The same spring 205 is fixedly installed on the pawl 204 and the inner wall of the hollow shaft 201. It can control the rotation of the hollow roller 2 when the inflatable airbag 21 needs to be wound up, without affecting the normal deployment of the inflatable airbag 21.

[0038] The mounting box 3 is set on one side of the mounting frame 1, and a partition is fixedly installed inside the mounting box 3. The air pump 31 is fixedly installed below the partition inside the mounting box 3, and the air outlet of the air pump 31 extends to the top of the partition and is fixedly installed with a one-way valve. The delivery pipe 32 is fixedly installed on the box and is sealed and rotatably connected to the hollow shaft 201. The air pump 3 can also be replaced by air pumping through the downhole compressed air system.

[0039] The top of the mounting box 3 is detachably and sealed with two air tanks 33 by threads. The air outlet of the air tank 33 is connected to the space above the partition inside the mounting box 3 and is equipped with a valve, which can quickly inject gas into the airbag 21 when it is necessary to quickly deploy the airbag 21.

[0040] There are two temperature sensors 4 and two gas sensors 41, which are fixedly installed on the front and rear sides of the mounting frame 1 respectively. They are used to monitor the temperature and gas concentration near the mounting frame 1 in the mine. They are convenient to work with external alarms to provide alarm effects when abnormalities occur. They are also convenient to work with controllers and other control components to control the motor 202, the air pump 31 and the valve located at the air outlet of the air tank 33.

[0041] In this embodiment, in order to control the airbag 21 to remain open when it is being rolled up, so as to facilitate the air discharge of the airbag 21 during the rolling up process, a pressure relief pipe is fixedly installed on the mounting box 3, and an electric control valve is fixedly installed on the pressure relief pipe.

[0042] In this embodiment, in order to provide protection for the motor 202, a protective cover is fixedly installed on the top of one side of the mounting frame 1.

[0043] The circuits, electronic components, and module mechanisms involved, as well as the material selection for the inflatable airbag, are all solved using existing and well-known technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0044] The selection of compressed gas in the gas storage tank 33 should be based on the actual usage environment. Flammable and explosive gases should not be used. Compressed nitrogen, carbon dioxide, etc. are better choices.

[0045] Working principle: In use, first install the mine-use inflatable firewall at the location requiring protection in the mine, ensuring a sealed connection between the mounting frame 1 and the inner wall of the roadway. Then, connect the power supply. When the temperature sensor 4 or gas sensor 41 detects an environmental anomaly, the air pump 31 can be started via an external controller. The air pump 31 inflates the hollow shaft 201 and hollow roller 2 through the delivery pipe 32. The gas enters the inflatable airbag 21 through the inflation pipe 211 and branch pipe 212. Simultaneously, the elastic rope 213 assists in the expansion of the inflatable airbag 21. Guided by the component, the inflatable airbag 21 unfolds smoothly in a predetermined direction to form a firewall, blocking potential dangers. When the danger is eliminated and the firewall needs to be retracted, the motor 202 is started. The motor 202 drives the ratchet 203 to rotate. Through the cooperation of the pawl 204 and the spring 205, the hollow roller 2 rotates, retracting the inflatable airbag 21. At the same time, the electric control valve on the pressure relief pipe opens to facilitate the release of air, completing the retraction process. Throughout the process, the air tank 33 can quickly inflate the inflatable airbag 21 in an emergency, improving the emergency response speed.
