Technical Field
[0001] The utility model relates to the technical field of water penetration detection, in particular to a mine water penetration detection device. Background Art
[0002] Coal mine water disaster is a common disaster in the construction and production process of mines. It can affect the production efficiency of mines at the very least, and cause serious accidents such as drowning and death at the worst. There are often some signs before the mine is flooded, such as red, sweating, water sounds, and cold air. Usually, we can know in advance whether the coal mine is likely to be flooded based on these phenomena. Accurately and timely forecasting the probability of mine waterlogging is a strong guarantee for people's lives and property.
[0003] The use of a water exploration drill for advance water exploration can achieve the purpose of water permeability detection. Drill holes underground for detection. During the drilling process, if any signs of permeability are found, such as significant softening in the hole, water flowing out along the drill pipe, and a sudden increase in flushing fluid, drilling must be stopped immediately. However, the drill bit and drill pipe cannot be removed to prevent the sudden outflow of harmful gases and large amounts of accumulated water. After the situation is clarified, all safety measures are prepared, and it is confirmed that there is no danger, the water can be slowly released by rotating the drill pipe.
[0004] In such situations, the drill bit and drill rod must remain in the borehole. To protect the drill rig and facilitate subsequent reinforcement operations, the drill rig must be removed. If the drill bit and drill rod are disconnected and removed, the drill bit and drill rod will lose effective support, making them vulnerable to pressure and dislodging, posing a risk. Therefore, we propose a mine water infiltration detection device. Utility Model Content

There are at least four rollers 12, and a push handle 13 is fixed above the base plate 1 on the side away from the drilling rig 2. The push handle 13 is parallel to the surface of the base plate 1. When the drilling rig 2 starts and drives the drill rod 3 to rotate, the push handle 13 can push the base plate 1 to move toward the inner wall of the well under the rolling action of the rollers 12, and then the drill rod 3 is used to drill the hole and perform detection.
[0027] The outer ring of the drill pipe 3 near the end of the joint 21 is surrounded by a ring block 31, and four sockets 311 are evenly opened on the outer ring of the ring block 31. An additional support member is provided, which consists of a screw barrel 4 and a support rod 41. The support rod 41 is screwed to the inside of the screw barrel 4 through the thread 411 of its outer ring. An insertion rod 43 is fixed to the end of the other side of the screw barrel 4, and the end of the support rod 41 is bent to the side.

During the drilling process of the drilling rig 2, if there are signs of air permeation such as significant softening in the hole, water flowing out along the drill pipe 3, and a sudden increase in flushing fluid, the drilling work is stopped immediately, and the bent part of the end of the support rod 41 is inserted into the socket 31 on the side of the ring block 31. 1, and the plug rod 43 at the end of the screw barrel 4 is close to the bottom or side inner wall of the well, and then the screw barrel 4 is rotated to increase the length of the support member formed by it and the support rod 41 until the plug rod 43 at the end of the screw barrel 4 is inserted into the bottom or side inner wall of the well, thereby realizing support inclined toward the direction of the drill pipe 3, and then another support member is used to support the well body on the opposite side of the previous support member in the same way or between the other side inner wall and the ring block 31, and the two support members jointly press against the drill hole drilled by the drill pipe 3 to lock the drill pipe 3, and then the locking bolt on the joint 21 can be loosened, the bottom plate 1 and the drilling rig 2 above it can be removed, and the support member can be used to support and lock the drill pipe 3 (such as Figure 4 As shown), it protects the drilling rig 2 without affecting subsequent reinforcement or inspection operations in the well.
[0028] A rubber sleeve 42 is fixed on the outer ring of the bent part at the end of the support rod 41, and the inner ring of the rubber sleeve 42 is tightly attached to the outer ring surface of the support rod 41. When the bent part at the end of the support rod 41 is inserted into the inside of the socket 311, the rubber sleeve 42 contacts the inner surface of the socket 311, achieving an anti-slip effect.

The support member composed of the screw barrel 4 and the support rod 41 can be placed on the surface of the base plate 1 when not in use. It is not easy to fall off due to the blocking effect of the gear rods 14.
[0030] During use, a plurality of support members consisting of screw holes and support rods 41 are placed on the surface of the bottom plate 1 and carried. The bottom plate 1 is pushed by the push handle 13 so that it moves in the mine under the rolling action of the roller 12, so that the drilling rig 2 is started and driven to rotate, and the bottom plate 1 is pushed so that the drill rod 3 is close to the inner wall of the well to be drilled for detection and analysis. If there are signs of air permeation such as significant softening in the hole, water flowing out along the drill rod 3, and a sudden increase in flushing fluid during the drilling process, the drilling work is stopped immediately, and the support member consisting of the screw barrel 4 and support rod 41 placed on the surface of the bottom plate 1 is removed, and the bent part of the end of the support rod 41 is inserted into the socket 311 on the side of the ring block 31, and the screw The insertion rod 43 at the end of the cylinder 4 is close to the bottom or side inner wall of the well, and then the screw cylinder 4 is rotated to increase the length of the support member formed by it and the support rod 41 until the insertion rod 43 at the end of the screw cylinder 4 is inserted into the bottom or side inner wall of the well, thereby realizing support inclined toward the drill pipe 3. After that, another support member is used and supported in the same way above the well body on the opposite side of the previous support member or between the other side inner wall and the ring block 31. The two support members jointly press against the drill hole drilled by the drill pipe 3 to lock the drill pipe 3. Then the locking bolt on the joint 21 can be loosened, and the bottom plate 1 and the drilling rig 2 above it can be removed to ensure safety. Finally, the support locking structure is as shown in FIG. Figure 4 shown.
