Description

Technical Field

[0001] The utility model relates to the technical field of water-release drilling, in particular to a water-control device for underground water-exploring and water-release drilling. Background Art

[0002] Water exploration refers to the use of advanced exploration methods during the mining process to determine the specific spatial location and conditions of water bodies in the roof, floor, side walls and front of the mining face. Its purpose is to make necessary preparations for the effective prevention and control of mine water. Water release refers to the use of safe methods such as drilling to release water after the situation is ascertained in order to prevent water disasters.

[0003] However, the following problems still exist in actual use:

[0004] (1) In the current coal mine exploration and drainage process, sometimes due to the high pressure of the explored water, the accumulated water will spray out from the borehole to a long distance, causing the construction site to be out of control, destroying the tunnel, threatening the tunnel support, etc., which will increase the danger of the coal mine exploration and drainage process.

[0005] (2) When the drill bit is drilling, the accumulated water is discharged through the drill pipe, while the mud and sand will adhere to the inner wall of the drill pipe. Since the internal space of the drill pipe is small, it will be difficult to clean the inner wall of the drill pipe. The long-term accumulation of impurities and stains will cause blockage of the drill pipe. Utility Model Content

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. The underground water exploration and drainage drilling water control device can block objects with large mud and sand through a filter net. When the water flow contacts the buffer plate, it drives the buffer plate to move, so that the first spring is stretched to achieve initial buffering.

The displacement of the second tooth plate squeezes the second spring to achieve a second buffering effect. The arrangement of this structure can effectively buffer the pressure generated when the accumulated water is pumped out to prevent the excessive pressure of the water from spraying out and causing chaos on the construction site, thereby solving the problem that in the current coal mine exploration and drainage process, sometimes due to the high pressure of the explored accumulated water, the accumulated water will spray out far along the borehole, causing the construction site to be out of control, destroying the tunnel, threatening the tunnel support, etc., which will increase the danger in the coal mine exploration and drainage process.

[0010] 2. The downhole water exploration and drainage drilling water control device drives the connecting rod to rotate by rotating the handle, thereby driving the second bevel gear to rotate, and the first bevel gear to rotate by the second bevel gear, thereby driving the rotating shaft to rotate, and the supporting shell is driven to rotate by the rotating shaft to cooperate with the third spring so that the brush plate can fit the inner cavity of the drill body to brush away the residual mud and sand on the inner cavity of the drill body.

Due to the small internal space of the drill pipe, it will be difficult to clean the inner wall of the drill pipe, and the long-term accumulation of long-term impurities and stains will cause blockage of the drill pipe.
