The device includes a platform, a sealing reinforcement mechanism, and a mine opening. The platform is arranged above the mine opening. A through hole is provided on the upper surface of the platform for installing the sealing reinforcement mechanism. A cover plate of the sealing reinforcement mechanism is inserted into the through hole. The sealing reinforcement mechanism is composed of a cover plate, a hydraulic pump c, a hydraulic rod c, a straight rod, and a fan plate. A straight rod for installing the hydraulic pump c is welded to the lower surface of the cover plate. The hydraulic pumps c are evenly distributed around the surface of the straight rod. By using the provided cover plate, hydraulic pump c, hydraulic rod c, straight rod, and fan plate in conjunction with the sealing ring, the mine opening surface is sealed by the cover plate and the sealing ring.

The support connecting plate 2014 includes a support plate 3 fixedly welded to the bottom of the I-shaped plate 2011 and a support column 4 fixedly welded to the bottom of the support plate 3.

[0034] Furthermore, the positioning structure 202 includes a positioning seat 2021 fixedly welded to the bottom of the support column 4, a cylinder 2022 installed on the top of the positioning seat 2021 by bolts, a lifting column 2023 fixedly mounted on the output shaft of the cylinder 2022, a guide column 2024 fixedly welded to the top of the positioning seat 2021, a positioning column 2025 installed inside the guide column 2024, a first hinged seat 2026 fixedly welded to the top of the positioning column 2025, a second hinged seat 2027 fixedly welded on the outer wall of the lifting column 2023, and a hinged plate 2028 hinged between the first hinged seat 2026 and the second hinged seat 2027.

[0038] Working principle: When in use, the mounting frame 1 is installed on both sides of the mine entrance, and the reinforcement sealing component 2 is lowered into the mine through the telescopic column 103. The lifting column 2023 is driven to descend by the cylinder 2022, and the lifting column 2023 drives the second hinge seat 2027 to descend. The second hinge seat 2027 drives the first hinge seat 2026 to move through the hinge plate 2028, and the first hinge seat 2026 drives the positioning column 2025 to move.

The impact causes the device to shift, improving the reinforcement and sealing effect. Air is introduced into the rubber airbag 2012 through the air pump 2013. The rubber airbag 2012 expands and fits the inner wall of the mine, sealing the mine entrance to prevent leakage of harmful gases and dust. When performing internal blasting, an impact force is generated on the protective plate 2032. The protective plate 2032 squeezes the reset spring 2033 and drives the damping T-shaped column to move. The damping T-shaped column drives the damping plate to move in the damping groove. The damping fluid produces a damping effect on the damping plate, ensuring that the reset spring 2033 can return to static balance, cushioning the generated impact force, and preventing the impact force from affecting the safe use of the telescopic column 103.
