AI Technical Summary
After prolonged use and repeated up-and-down movement, existing geological exploration borehole water inrush sealing devices become loose from the borehole wall soil due to the loosening of the fixing components such as the insertion rod and the insertion block. This results in a lack of durability in sealing effectiveness and makes the devices susceptible to accidental triggering or human damage, thus losing their sealing function.
The structure employs a vertical tube with inserted rods and anchor rods. The anchor rods are clamped onto the vertical tubes via dovetail grooves to compress the soil and enhance soil compaction. Combined with a special key structure, it prevents the inserted rods from loosening and being accidentally triggered. Installation and disassembly are carried out using a special key structure and specific operating methods.
It improves the durability and sealing effect of the sealing device, avoids loosening and accidental disassembly of the insertion rod, enhances the resistance to water pressure, and ensures that the sealing device works stably under different water pressure conditions.

Description
TECHNICAL FIELD
[0001] The present application belongs to the field of geological exploration hole plugging device, and particularly relates to a geological exploration hole water gushing plugging device. BACKGROUND
[0002] In the process of geological exploration, the staff samples the soil by opening a geological exploration sampling hole on the ground, and the exploration hole may be sampled again subsequently, so it is necessary to temporarily plug the geological exploration sampling hole to prevent underground river water from flowing into the hole and gushing out of the opening end of the exploration hole, causing the exploration hole to collapse and causing changes in the surrounding topography and adverse effects on the surrounding ecological environment.
[0003] In the prior art, the plugging device is placed in the exploration hole, and the fixing members such as the insertion rod and the insertion block are inserted into the hole wall, but due to the real-time change of underground water pressure, the increase of water pressure will cause the fixing members such as the insertion rod and the insertion block to compress the soil of the hole wall, and the decrease of water pressure will cause the plugging device to move downward under the force of gravity, so that there is a gap between the fixing members such as the insertion rod and the insertion block and the soil, which is very small at the beginning, but will become larger and larger after a long time of use and repeated upward and downward movement, causing the fixing members such as the insertion rod and the insertion block to loosen with the soil of the hole wall, and finally the plugging device loses the plugging effect; especially in places where the soil is soft, the gap will increase quickly, causing the plugging device to be not durable.
[0004] In the existing plugging device, the plugging effect is affected by the number of fixing members such as the insertion rod and the insertion block, and if the number is small, the grip is not enough, and if the number is large, the structure is complex, and the amount of soil in contact with the fixing members and bearing force is reduced, so the soil is more likely to loosen and it is difficult to achieve balance.
[0005] Since the underground water mostly gushes upward, the existing plugging device is provided with a trigger device, which will be plugged when subjected to an upward force, and when disassembled, the insertion rod and the insertion block will be retracted and separated from the soil by applying a downward force to the trigger device; however, when the underground water pressure decreases, a downward suction force will be generated, or a stone will fall and hit the trigger device, or an animal will pass and step on the trigger device, which will trigger the insertion rod and the insertion block to retract, causing the plugging device to lose grip, and when the water pressure rises again, water will gush out, which is not a reliable structure. Sometimes people find the plugging device but do not know what it is, and out of curiosity, they will try to touch it, which is easy to trigger disassembly and cause the plugging device to fail to continue plugging.

[0057] Working principle:
[0058] In use, the device needs to be installed in the exploration hole that needs to be plugged, specifically: the end of the insertion rod 4 away from the axis of the vertical cylinder 1 is inserted into the first through slot 16 and the insertion rod 4 does not protrude from the vertical cylinder 1; the circular ring 9 is moved upward along the vertical rod 5 to be close to the first disc 6, the lower end of the connecting rod 10 is close to the second disc 7, the upper end of the anchoring rod 11 is close to the vertical rod 5, the whole composed of the vertical rod 5, the first disc 6, the second disc 7, the third disc 8 and the circular ring 9, the connecting rod 10 and the anchoring rod 11 is placed in the vertical cylinder 1 from the lower end of the vertical cylinder 1 upward, and the first disc 6 is placed below the insertion rod 4; the key is inserted into the through hole 3 from top to bottom, the inclined surface on the baffle 35 is pressed to move the baffle 35 into the blind hole 34, then it is passed through the insertion slot 31 to the connecting slot 12 position, the short rod 28 on the key is passed through the horizontal slot 21 and placed in the circular groove 23 and rotated 90 degrees; keep this state, place the vertical cylinder 1 in the exploration hole that needs to be plugged; control the key to make the vertical slot 14 correspond to each group of insertion rod 4 one by one upward and downward, then keep the end cover 2 and the vertical cylinder 1 from moving by stepping and other methods, at the same time, pull the key upward to drive the first disc 6 to move upward; on the one hand, the insertion rod 4 is extruded by the inclined slot 15 to move outward, the outer end of the insertion rod 4 protrudes from the vertical cylinder 1 and is inserted into the soil, the vertical plate 13 is placed in the corresponding vertical slot 14 to prevent the insertion rod 4 from moving to the middle; the rope 33 is pulled tight when the insertion rod 4 moves outward; on the other hand, the connecting rod 10 is extruded by the second disc 7 to make the lower end of the connecting rod 10 close to the inner wall of the vertical cylinder 1, then the connecting rod 10 and the anchoring rod 11 are moved upward by the second disc 7, the upper end of the anchoring rod 11 protrudes from the vertical cylinder 1 and is inserted into the soil through the second through slot 17, and the upper end of the anchoring rod 11 gradually protrudes outward and rotates outward until the dovetail slot 18 at the lower end of the anchoring rod 11 is clamped on the vertical rod 5; the third disc 8 is placed in the lower end of the vertical cylinder 1 to seal the lower end of the vertical cylinder 1, that is, the installation is completed, and the key is removed; the baffle 35 is reset to close the through hole 3 under the action of the spring 36, this closure is only to prevent debris from falling into the vertical cylinder 1 through the through hole 3, and the gap around the baffle 35 can still pass air.
[0059] In subsequent use, the water pressure changes in real time.
[0060] When the peak pressure of water upward surge is small, the third disc 8 moves upward, the connecting rod 10 and the anchoring rod 11 are moved upward by the second disc 7, and the dovetail slot 18 at the lower end of the anchoring rod 11 is clamped on the vertical rod 5, which will extrude the soil above the anchoring rod 11 to make the soil dense, and the water level will drop after the anchoring rod 11 and other devices are reset under the action of gravity; the soil above the anchoring rod 11 becomes dense to enhance the ability to resist the rise of water pressure and improve the plugging effect; and when the peak pressure of water upward surge is small, the first disc 6 moves within the length range of the vertical plate 13 and does not impact the insertion rod 4, the air above the third disc 8 is discharged through the through hole 3 and does not impact the vertical cylinder 1, so the insertion rod 4 remains in place and avoids loosening caused by upward and downward movement; therefore, when the peak pressure of water upward surge is small, only the anchoring rod 11 plays a supporting role.
[0061] When the water surges upward with a large peak pressure, the third disc 8 moves upward, on the one hand, the second disc 7 drives the connecting rod 10 and the anchoring rod 11 to move upward, because the dovetail groove 18 at the lower end of the anchoring rod 11 is clamped on the vertical rod 5, the anchoring rod 11 will form extrusion to the soil above it, so that the soil becomes dense; on the other hand, the first disc drives the plug 22 to block the through hole 3, the impact force of the water upward is transmitted to the insertion rod 4, which and the anchoring rod 11 jointly support, preventing the water pressure from driving the vertical cylinder 1 out of the exploration hole, and improving the plugging effect.
[0062] When the water surges downward to form a negative pressure, the third disc 8 moves downward, the first disc 6 drives the ring 9 to move downward, so that the anchoring rod 11 retreats into the vertical cylinder 1, and the external air enters the vertical cylinder 1 through the through hole 3, when the third disc 8 is separated from the vertical cylinder 1, the exploration hole is connected with the outside, no longer forming pressure on the third disc 8, the third disc 8 does not move downward, and does not form downward suction force on the vertical cylinder 1 and the insertion rod 4, so the insertion rod 4 remains in place and does not move up and down to cause loosening.
[0063] When disassembling, the key is inserted again, the short rod 28 pushes the first disc 6 to move downward and makes the first disc 6 placed below the insertion rod 4, drives the anchoring rod 11 to retreat into the vertical cylinder 1, the insertion plate 26 on the key is inserted into the insertion slot 31 on the fourth disc 30, the fourth disc 30 is adsorbed at the lower end of the thick round rod 25, the rope rod 32 is inserted between the ropes 33, the key is rotated to drive the fourth disc 30 and the rope rod 32 to rotate through the insertion plate 26, the rope rod 32 winds the ropes 33, drives the insertion rod 4 to move to the middle and separates from the soil; then the key is continuously rotated to make the vertical groove 14 not correspond to the insertion rod 4 up and down, so that the key is pulled upward, and the whole vertical cylinder 1 is driven to move out of the exploration hole.
[0064] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, the skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
