TECHNICAL FIELD

[0001] The utility model relates to waterproof engineering technical field, concretely is quick plugging sealing assembly for mine water geological storage. BACKGROUND

[0002] With the continuous increase of mining depth, the safe geological storage of mine water becomes the core link of water disaster prevention and protection of groundwater resources. Mine water is usually rich in minerals, suspended solids and corrosive ions. If not effectively sealed, not only will it cause water pollution, but also may cause safety accidents such as ground structure instability and water inrush. In the old goaf treatment, abandoned mine reutilization and groundwater storage engineering, the sealing assembly needs to operate stably for a long time to cope with the complex water pressure changes.

[0003] At present, the sealing technology commonly used in mine water geological storage has many deficiencies, of which the most important is the limitation of static sealing structure. The traditional sealing assembly adopts static sealing methods such as rubber ring extrusion and cement grouting, which rely on the initial pressure during installation to achieve sealing. However, during the mining process, the water pressure in the mine will fluctuate periodically due to mining influence, seasonal water level changes and other factors (the fluctuation range often exceeds 10MPa). Under repeated pressure impact, the sealing element of static sealing structure is prone to fatigue deformation and elastic attenuation, resulting in gaps on the sealing surface and eventually causing leakage.

[0004] Therefore, the quick plugging sealing assembly for mine water geological storage is provided to overcome the above-mentioned defects. SUMMARY

[0005] The purpose of the utility model is to provide a quick plugging sealing assembly for mine water geological storage to solve the problems raised in the background technology.

A telescopic inner rod is fixedly installed at the inner wall bottom of the connecting sleeve rod. A push block with an inclined edge position is arranged below the telescopic inner rod. A push groove is arranged below the push block. A slidable transmission rod is arranged on the outer wall of the connecting sleeve rod. The part of the transmission rod in the connecting sleeve rod is fixedly connected with a drive block with an inclined bottom. The end of the transmission rod away from the connecting sleeve rod is fixedly connected with the retaining piece. A return spring is fixedly connected between the inner wall of the connecting sleeve rod and the inner wall of the drive block.

[0007] Further, the bottom of the connecting sleeve rod is fixedly connected with a water collecting groove, and the radius of the water collecting groove is greater than the radius of the connecting sleeve rod.

[0008] Further, the bottom surface of the push block is fixedly connected with a connecting rod at the middle position, and the side of the connecting rod away from the push block is fixedly connected with a push groove.

[0009] Further, the bottom surface of the push groove is fixedly bonded with a second sealing gasket at the edge position, and the second sealing gasket is attached to the inner wall of the water collecting groove in the initial state.

[0010] Further, the top end of the water collecting groove is funnel-shaped, and the specific shape of the push groove is also funnel-shaped, and the push groove and the top end of the water collecting groove are matched with each other.

[0011] Further, the outer wall of one of the driving blocks is fixedly connected with two transmission rods, and the reset spring is coaxially arranged with the transmission rod.
