Description
A gas prevention and sealing reinforcement structure Technical Field
[0001] This invention relates to the field of gas control technology, specifically a gas control sealing and reinforcement structure. Background Technology
[0002] Gas prevention and sealing reinforcement structures are a safety protection technology specifically designed for underground working environments such as coal mines. Their main function and purpose is to effectively prevent gas leakage and accumulation by enhancing the sealing of roadways or mining faces, thereby reducing the risk of gas explosions. In daily applications, this structure is widely used in coal mining, tunnel engineering, and other underground work sites where gas hazards may exist.
[0003] Gas control sealing and reinforcement structures typically consist of a sealing material layer, a reinforcement support structure, and a monitoring device. Their working principle involves forming a barrier against gas through the sealing material layer, while the reinforcement support structure enhances the stability and durability of the sealing layer. The operation process includes laying the sealing material, installing the reinforcement structure, and setting up the monitoring device. This structure demonstrates significant advantages in practical applications, such as good sealing performance, structural stability, and ease of maintenance.
[0004] However, in actual use, most of the existing equipment relies on the rigidity of the materials themselves. Under external impact, it is prone to deformation due to uneven local stress, which cannot effectively strengthen weak points. Moreover, the existing equipment often adopts independent fixing methods, such as simple bolt fixing, without linkage mechanism, making it difficult to fix in time when needed. Furthermore, the fixing is uneven, and it is easy to loosen after long-term use, affecting the sealing protection. In view of this, we propose a gas prevention and sealing reinforcement structure.

[0019] Compared with the prior art, the present invention provides a gas prevention and sealing reinforcement structure, which has the following beneficial effects:
[0020] 1. In order to enable the gas prevention and control sealing and reinforcement structure to withstand external impacts, a reinforcement component is provided. This component, together with a hydraulic device, pushes the extrusion plate along the opening and slides precisely with the help of a slide rail and a slider. The extrusion plate, together with the sliding groove and sliding shell of the block, applies stable pressure to a specific area, compensates for any structural weaknesses in the outer shell, and ensures that the sealing and reinforcement structure can withstand external impacts and maintain a good sealing state in gas prevention and control scenarios.
[0021] 2. To prevent the gas prevention and sealing reinforcement structure from loosening and affecting the sealing and protection effect, a fixing component is installed. When this component works in conjunction with the reinforcement component, the sliding plate moves along with the square plate. The push plate of the square plate squeezes the limiting rod, causing the round rod to slide down the inclined groove. The round rod and the sliding rod work together to allow the spikes to penetrate the surrounding mounting surface. The sliding rod slides in the limiting groove, and the limiting rod slides between the push plate and the square rod, ensuring precise action and firmly rooting the entire gas prevention and sealing reinforcement structure, preventing loosening from affecting the sealing and protection effect.
[0022] 3. To ensure the long-term stable operation of the gas prevention and sealing reinforcement structure, a cleaning component is installed. This component works in a slot inside the outer casing, where a long spring rod and a short spring rod are connected to steel brushes No. 1 and No. 2, respectively. When the round rods, sliding rods, and other components of the fixed component move, the steel brushes clean the dust and debris on their surfaces in a timely manner under the action of the springs, preventing dirt accumulation from hindering the movement of the components, ensuring the long-term stable operation of the entire gas prevention and sealing reinforcement structure, and reducing potential malfunctions.

When there may be external impact in the gas prevention environment or when it is necessary to strengthen the seal, the hydraulic device 42 is activated. The piston end of the hydraulic device 42 is connected to the connecting block 43. The piston extends and retracts, causing the connecting block 43 to move. At the same time, the sliding plate 44 drives the extrusion plate 45 to move. The extrusion plate 45 can slide in the opening 413 on the outside of the outer shell 1. Multiple sets of reinforcing components 4 ensure that the force on both sides is even. The sliding shell 411 on the outside of the extrusion plate 45 can slide in the sliding groove 410 on the inside of the block 48. At the same time, the baffle 412 can slide on the inside of the outer shell 1. These structures together ensure the stability of the extrusion plate 45 during movement. When the hydraulic device 42 pushes the extrusion plate 45 to move to a specific area, the extrusion plate 45 applies stable pressure to areas where there may be structural weaknesses, strengthens the overall stability of the outer shell 1, and ensures that the sealing and reinforcing structure can resist external impact and maintain a good sealing state in the gas prevention and control scenario.
[0035] In one embodiment of the present invention, a fixing component 5 is provided on the outer side of the outer shell 1. The fixing component 5 includes an inclined groove 51.

The spike 58 is set on the outside of the outer shell 1. At the same time, when the reinforcing component 4 is working, the slide plate 44 moves along with the square plate 52. The push plate 53 on the square plate 52 presses the limiting rod 56 as the square plate 52 moves. The limiting rod 56 can slide between the push plate 53 and the square rod 54. The movement of the limiting rod 56 drives the round rod 55 to move. The round rod 55 slides in the inclined groove 51 on the outside of the housing 1, providing guidance for the movement of the round rod 55 and the sliding rod 59.

Simultaneously, a long spring rod 62 and a short spring rod 64 are installed in the slot 61 inside the outer casing 1. In their natural state, the long spring rod 62 and short spring rod 64 are under compression or tension, positioning steel brush 63 and steel brush 65 in suitable positions to clean the relevant components. When components such as round rod 55 and sliding rod 59 of the fixing assembly 5 move, steel brush 63 and steel brush 65, under the elastic action of the long spring rod 62 and short spring rod 64, promptly clean dust and debris from their surfaces, preventing dirt accumulation from hindering component movement, ensuring the long-term stable operation of the entire gas prevention and sealing reinforcement structure, and reducing potential malfunctions.
[0037] Working principle: First, the outer shell 1 serves as the main structure. The mounting plate 41 on its inner side provides the mounting base for the reinforcing components 4. The hydraulic device 42 on the mounting plate 41 is the power source. When there may be external impact in the gas control environment or when reinforcement is required, the hydraulic device 42 is activated. The piston end of the hydraulic device 42 is connected to the connecting block 43. The piston's extension and retraction drive the connecting block 43 to move. Simultaneously, the sliding plate 44 drives the extrusion plate 45 to move. The extrusion plate 45 can slide within the opening 413 on the outer side of the outer shell 1. Multiple sets of reinforcing components 4 ensure even force distribution on both sides. The sliding shell 411 on the outer side of the extrusion plate 45 can slide within the opening 413 on the outer side of the outer shell 1. The extrusion plate 45 slides within the groove 410 on the inner side of block 48, while the baffle 412 can slide within the outer shell 1. These structures together ensure the stability of the extrusion plate 45 during movement. When the hydraulic device 42 pushes the extrusion plate 45 to a specific area, the extrusion plate 45 applies stable pressure to areas where there may be structural weaknesses, strengthening the overall stability of the outer shell 1 and ensuring that the sealing and reinforcement structure can withstand external impacts and maintain a good sealing state in gas prevention scenarios. At the same time, when the reinforcement component 4 is working, the slide plate 44 moves along with the square plate 52, and the push plate 53 on the square plate 52 extrudes the limiting rod 5 as the square plate 52 moves. 6. The limiting rod 56 can slide between the push plate 53 and the square rod 54. The movement of the limiting rod 56 drives the round rod 55 to move. The round rod 55 slides in the inclined groove 51 on the outside of the outer shell 1, providing guidance for the movement of the round rod 55 and the sliding rod 59. At the same time, the spikes 58 pass through and penetrate the surrounding mounting surface during the downward movement of the round rod 55, thereby fixing the entire structure. The sliding rod 59 on the outside of the round rod 55 can slide in the limiting groove 57, ensuring the accuracy of the movement of the round rod 55. Multiple sets of fixing components 5 ensure the uniformity and reliability of the fixing effect, avoiding structural loosening that would affect the sealing and protection effect. Furthermore, the inner shell 1 A long spring rod 62 and a short spring rod 64 are installed in the side slot 61. In their natural state, the long spring rod 62 and the short spring rod 64 are in a certain state of compression or tension, so that the No. 1 steel brush 63 and the No. 2 steel brush 65 are in the right position to clean the relevant components. When the round rod 55, sliding rod 59 and other components of the fixed assembly 5 move, the No. 1 steel brush 63 and the No. 2 steel brush 65 clean the dust and debris on their surfaces in a timely manner under the elastic action of the long spring rod 62 and the short spring rod 64, preventing dirt from accumulating and hindering the movement of components, ensuring the long-term stable operation of the entire gas prevention and sealing reinforcement structure, and reducing potential failures.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
