Technical Field

[0001] The invention relates to the technical field of drilling structures, and in particular to a drilling structure used in an underwater geological environment. Background Art

[0002] Drilling institutions are of great significance for geological exploration, geological environment analysis, and geological sample collection. However, current drilling institutions can only drill on the ground and cannot drill in special environments such as underwater, thus affecting the progress of geological work.

[0003] The Chinese patent with the patent publication number CN116122749A discloses a drilling head structure and an in-situ leaching drilling platform, including a first sprocket assembly; a second sprocket assembly; a driving device, whose output end is coaxially connected with the input shaft of the second sprocket assembly; a chain, arranged between the first sprocket assembly and the second sprocket assembly, for transmitting the movement on the second sprocket assembly to the first sprocket assembly; a shoulder beam assembly, connected to the chain; and a square active drill rod, arranged on the shoulder beam assembly. The present invention can complete the pressurized drilling process within 200m when drilling a hole, and does not require a rod turning operation when drilling a 9m drill rod, which not only improves the hole formation rate and avoids the quality accident of the hole being inclined due to multiple rod turning, but also reduces the auxiliary construction time and improves the construction efficiency. It is highly practical and worth promoting.

[0004] The Chinese patent with the patent publication number CN112252996A discloses a drilling boom structure, which relates to the technical field of coal mine tunnel excavation equipment, including a drill boom assembly, a transition connection seat, a detection slide and a rock drilling slide; one end of the drill boom assembly is connected to the main machine; the other end of the drill boom assembly is connected to one end of the transition connection seat, the rock drilling slide is arranged above the transition connection seat, and a rock drilling device is arranged on the rock drilling slide; the detection slide is connected to the transition connection seat; the other end of the detection slide is provided with a detection device. The drilling boom is a modular structure, which is convenient for the transformation of existing equipment. It is combined with drilling and exploration, and has high operating efficiency. It is easy to operate and can be explored as you dig.

[0005] The Chinese patent with the patent publication number CN117703278A discloses a drill bit structure and a coal mine drilling machine, which belongs to the field of coal mine mechanical equipment, including a support seat, the upper end of the support seat is rotatably connected to a lifting device on the left side, and the upper end of the support seat is rotatably connected to a base on the right side, the lower left end of the base is rotatably connected to the lifting device, and the upper end of the base is movably connected to a drilling device, and the base is provided with a pushing mechanism, and the pushing mechanism includes a motor fixedly connected to the right side of the base. When drilling difficulties occur, the card block is disengaged from the card slot, and the rotating block rotates relative to the slider, so that the drilling device cannot be forced to move, thereby effectively protecting the drilling device from damage. When the card block moves, the card block drives the second round block to move, and through the first one-way valve and the second one-way valve, the air pressure inside the cavity is continuously increased, so that the card force between the card block and the card slot is continuously increased, so that the moving force of the slider driving the drilling device will become larger and larger, thereby improving the drilling effect.

The second driving motor 403 works to drive the sliding seat 405 to move so that the electric wrench 402 moves up and down, which facilitates the electric wrench 402 to align with the wrench connector 306 of the connecting seat 3. The third driving motor 404 works to drive the rotating ring 401 to adjust the electric wrench 402 to rotate, so that the electric wrench 402 can drive the wrench connector 306 at different angles, so as to achieve the purpose of tightening the rope of the fixed anchor 6.

[0069] Working principle of the present invention: when in use, first place the insertion tube 105 of the underwater pipeline mechanism 1 to the bottom of the water to be drilled, then place the fixed anchor 6 at the designated position by an external staff, and at the same time wrap the rope on the fixed anchor 6 around the clamping wheel 302 of the corresponding connecting seat 3, then work through the moving mechanism 4, work through the second driving motor 403, drive the sliding seat 405 to move so that the electric wrench 402 moves up and down, so that the electric wrench 402 is aligned with the wrench connector 306 of the connecting seat 3, and drive the rotating ring 401 to rotate the electric wrench 402 through the third driving motor 404, so that the electric wrench 402 can drive the wrench connector 306 at different angles, so as to achieve the purpose of tightening the rope of the fixed anchor 6. The wrench connector 306 is rotated to drive the first bevel gear 304 to rotate the second bevel gear 305, and the second bevel gear 305 rotates to drive the clamping wheel 302 to rotate to tighten the rope of the fixed anchor 6. The ratchet 307 is locked by the pawl 308, thereby locking the clamping wheel 302, so as to prevent the clamping wheel 302 from reversing, causing the rope connected to the fixed anchor 6 to loosen, resulting in the problem of the underwater pipeline mechanism 1 and the water driving mechanism 2 tipping over;

[0070] Next, by fixing the bottom plate 201 of the water driving mechanism 2 to the fixing seat 103 of the underwater pipeline mechanism 1, the worker puts the assembled drill bit 503 and the second connecting rod 502 into the waterproof pipe 101 of the underwater pipeline mechanism 1 through the circular hole on the bottom plate 201, and connects different numbers of drill bits 503 to the second connecting rod 502 in turn according to the situation, and then connects the outlet head 207 to the topmost drill bit 503, and the water flows into the first water inlet hole 2078 through the first water inlet pipe 2074, and then flows into the second water inlet hole 5013 of the first connecting rod 501, and then flows into the second water inlet hole 5013 of the second connecting rod 502, flows into the drill bit working section 5032 through the annular groove 5023 and the water outlet ring 5036, and finally flows out from the hole below the drill bit working section 5032. Through the action of the water flow, it is used to cool the protrusion 5033 and facilitate the work of the protrusion 5033, thereby improving the working efficiency of the protrusion 5033. At the same time, the water flow is mixed with the soil and rocks broken by the protrusion 5033, enters the return water hole 5035 through the return water groove 5034, and then enters the second water outlet hole 5012 of the second connecting rod 502 through the second water outlet hole 5012, passes through the second water outlet hole 5012 of the first connecting rod 501 and then enters the first water outlet hole 2077, and is discharged through the first water outlet pipe 2073, thereby realizing circulation discharge and improving underwater drilling efficiency.

[0071] At the same time, the hydraulic cylinder 206 drives the second triangular plate 204 to move downward to realize the compression of the spring 205, so that the spring 205 produces elasticity, and at the same time, the elastic force of the spring 205 compresses the first triangular plate 203 so that the first triangular plate 203 has a downward force, so that the first triangular plate 203 drives the lead-out head 207 to give a downward pressure to the mining mechanism 5, which is convenient for the mining mechanism 5 to drill the ground. At the same time, when it is necessary to increase the first connecting rod 501 to meet the drilling depth, the lead-out head 207 is manually rotated to separate the lead-out head 207 from the top first connecting rod 501, and then the hydraulic cylinder 206 is extended to drive the second triangular plate 204 to move upward, so that the lead-out head 207 is separated from the first connecting rod 501, and another first connecting rod 501 is installed on the top first connecting rod 501, and then the lead-out head 207 is installed on the top first connecting rod 501, thereby increasing the drilling depth and improving work efficiency.
