[0002] A reef blasting ship is a ship used for drilling, charging and detonating reefs. It is equipped with multiple movable rock drills and is also called a drilling and blasting ship. The existing technology mainly involves drilling holes in the reef first, and then inserting explosive tubes into the holes to blast the reefs. When drilling holes in the reefs, the equipment is easily damaged due to the high hardness of the reefs, which affects the normal use of the equipment.

[0003] The related technology (publication number CN215150603U) discloses an underwater reef blasting drilling device, comprising a main body, a rotating base arranged on one side of the main body, a fixing ring arranged on one side of the rotating base, a drilling rod arranged on one side of the rotating base and located on the inner side of the fixing ring, and a locking component arranged on one side of the fixing ring for convenient replacement of the drilling rod, wherein the locking component comprises a plurality of evenly arranged mounting grooves opened on one side of the fixing ring, a guide rod arranged at the bottom of the mounting groove, a first spring sleeved on the outer side of the guide rod, and a sliding block arranged at one end of the first spring. The utility model provides a main body, a drilling rod, a first spring and a guide groove, and the first spring squeezes a fixing ball on one side of the sliding block into the locking groove, so that the fixing ball can lock and fix the locking groove on one side of the drilling rod, thereby solving the problem that the existing equipment is inconvenient to disassemble and replace, which easily leads to cumbersome equipment maintenance operations, reduces the work efficiency of the equipment hole rotation operation, and affects the normal use of the equipment.

[0022] Compared with the prior art, the underwater drilling and reef blasting equipment of the present invention has the following beneficial effects:

[0023] First, the replacement of the existing drill bit cannot be completed directly during the underwater construction operation. If there is a need to replace the drill bit, the rock drill must be hoisted onto the hull as a whole before the replacement work can be carried out. The whole operation process is complicated. The present invention can realize the circumferential rotation of various movable columns, balls, and drill bits with the third drive shaft as the axis through the cooperation of the third drive shaft, the connecting plate, and the fan-shaped mounting plate. When the drill bit is aligned with the limit slide rail, the drill bit automatically extends downward out of the hollow cylindrical body. The present invention can realize that the drill bit automatically extends downward when it rotates to the bottom of the limit slide rail, and realizes the free conversion of different types of drill bits in the hollow cylindrical body cavity. The whole replacement process can be carried out in an underwater environment, that is, drill bits of different hardness or shapes can be replaced in an underwater environment according to actual drilling needs, avoiding the disadvantage of having to hoist the rock drill as a whole onto the hull to carry out the replacement work, saving the complex process of repeatedly hoisting the rock drill equipment as a whole, reducing the overall construction time, and avoiding the frequent overall hoisting that will bring additional safety hazards and equipment loss problems;

[0024] Second, the present invention can realize that the third drive shaft stops after rotating the same angle each time through the cooperation of the second drive shaft, the drive block, the toggle pin, the fan-shaped frame, the limit block and other components, that is, the intermittent operation of equidistant rotation is realized, thereby ensuring the equidistant intermittent operation of the third drive shaft, the connecting plate and the fan-shaped mounting plate. The present invention can ensure that after each rotation operation is completed, one group of drill bits accurately corresponds to the bottom of the limit slide rail and reaches a stable state without further rotation, thereby ensuring the stability of the drill bit in the subsequent drilling operation process, effectively avoiding the problems of drilling deviation, reduced efficiency or damage to the drilling equipment caused by the instability of the drill bit, and improving the quality and reliability of the drilling operation;

[0025] 3. In the present invention, the number of limit blocks and fan-shaped mounting plates is the same and corresponds to each other up and down, so as to ensure that when the driving block is stabilized at the limit block, the drill bit below the fan-shaped mounting plate accurately corresponds to the bottom of the limit block. At this time, the driving block, the third driving shaft, the fan-shaped mounting plate and the drill bit are all stable after rotation, that is, the drill bit reaches a stable state at this time and will not rotate further;

[0026] Fourth, in the present invention, the four sets of drill bits can be made of different hardness or different shapes as needed. When facing complex working conditions with different hardness of seabed rocks or different borehole diameters, the drill bits can be flexibly replaced according to actual conditions. This replacement method is not limited by a specific form, which greatly enhances the practical value of the present invention in underwater reef blasting and drilling construction, and can effectively cope with a variety of complex and changeable construction conditions to ensure the smooth progress of drilling operations and construction quality;

[0027] 5. In the present invention, when the ball moves to the limit slide rail, the ball automatically slides down along the inner cavity of the limit slide rail by continuing to rotate clockwise, so that the drill bit at the bottom of the ball automatically extends downward out of the hollow cylindrical body to perform subsequent drilling operations, while other drill bits remain in the hollow cylindrical body and will not interfere with or affect the drilling;

[0028] Sixth, in the present invention, the first drive shaft in the housing rotates, which can cause the hollow cylindrical body and the drill bit extending from the hollow cylindrical body to rotate synchronously in the circumferential direction, so that the drill bit can drill holes in underwater rocks, and the first drive shaft and the drill bit are coaxially arranged up and down to ensure that the centers of rotation of the two are the same, and the hollow cylindrical body rotates with the first drive shaft as the axis, which will not affect the normal drilling operation of the drill bit;

[0029] 7. In the present invention, a dosing unit is arranged around the drill bit extending downward. The dosing unit and the drill bit are independent of each other in space and do not interfere with each other. This arrangement of the two enables the dosing process to be carried out directly after the drilling operation is completed, thereby effectively improving the construction efficiency, optimizing the construction process, and ensuring the accuracy and safety of the drilling and dosing operations;

[0030] 8. In the traditional method of dosing, the dosing is often done through a hollow tube. This method has an inherent defect, that is, it is easy to cause the explosives to be unevenly distributed in the hole, which in turn has an adverse effect on the subsequent reef blasting effect. In the present invention, when the second hole position intermittently corresponds to the first hole position, the dosing operation can be carried out normally, and the second hole position and the first hole position are arranged equidistantly along the circumferential direction. This layout method can ensure that the explosives are evenly distributed in the hole position after dosing, thereby more effectively ensuring the effect of the subsequent reef blasting operation and improving the quality and efficiency of the reef blasting operation.

[0031] 9. In the present invention, the second hole position and the first hole position can intermittently correspond to each other. When the two correspond to each other, the drug delivery action can be performed. When the two do not correspond, the explosives delivered by the drug delivery barrel can be temporarily stored at the inclined portion, the first baffle plate, and the second baffle plate. This temporary storage mechanism provides sufficient time for the explosives to evenly fill the inner cavity of the inclined portion, the first baffle plate, and the second baffle plate, effectively preventing the problem of uneven distribution of explosives caused by more explosives accumulation near the drug delivery barrel and too little explosives far from the drug delivery barrel, thereby ensuring the uniform distribution of explosives in the entire drug delivery area, which is conducive to the smooth development of subsequent reef blasting operations and the achievement of reef blasting effects;

[0032] 10. In the present invention, the second hole position can intermittently correspond to the first hole position through the intermittent circumferential rotation of the hollow drum relative to the first baffle, that is, intermittent feeding is achieved, which provides sufficient time for the explosive to evenly fill the inner cavity of the inclined part, the first baffle and the second baffle;

[0033] 11. In the present invention, when the second hole position corresponds to the first hole position, the explosive can be dropped downward through the gap between the inner tube and the connecting block, and the drill bit penetrates the inner cavity of the inner tube from top to bottom, so the rotation of the drill bit realizes drilling, and the dropping of the explosive in the gap between the inner tube and the connecting block does not interfere with each other, so that after the drilling operation is completed, the dropping process can be directly carried out;

[0034] 12. The present invention can realize intermittent rotation of the hollow drum through the intermittent rotation of the gear ring, can realize intermittent rotation of the gear ring through the circumferential rotation of the shift block, and can realize stability of the gear ring after rotation through the limit plate and the recessed portion, that is, realize stability of the hollow drum after circumferential intermittent rotation, and ensure stability of the second hole position on the hollow drum after rotation;

[0035] 13. The present invention can realize the rotation of the gear ring, the hollow rotating cylinder and the second hole position once by rotating the rotating seat and the shifting block for one circle, so that the second hole position corresponds to the first hole position, and the explosive can be dropped through the second hole position and the first hole position in a connected state; by continuing to rotate the rotating seat and the shifting block for one circle, the gear ring, the hollow rotating cylinder and the second hole position can be rotated once again, and the second hole position is misaligned with the first hole position, and the second hole position corresponds to the second baffle plate. At this time, it is impossible to continue to drop medicine. The medicine dropped through the medicine dropping barrel can be temporarily stored in the inclined part, the first baffle plate and the inner cavity of the second baffle plate, so as to prepare for the storage of subsequent uniform explosives.

[0036] 14. In the present invention, the first hole positions and the second hole positions are respectively arranged at equal intervals, that is, the interval between two adjacent first hole positions or two adjacent second hole positions is 60 degrees, and the angle of each intermittent rotation of the second hole position is 30 degrees, thereby enabling the second hole position to correspond to the first hole position when rotating once, and to be staggered with the first hole position when rotating again, and to provide sufficient time for storing a sufficient amount of medication when the two are in a staggered state;

[0037] 15. In the present invention, the inclined portion is arranged obliquely, so that the explosives at the second baffle and the first baffle can be accumulated along the inclined portion toward the second baffle under the action of gravity, thereby ensuring that the subsequent explosives can be accurately delivered through the first hole opened at the second baffle, thereby improving the accuracy and reliability of the delivery, and ensuring that the entire delivery process is carried out smoothly according to the predetermined design;

[0038] 16. The present invention can promote the support arm to move in the vertical direction through the cylinder, the top plate and the lifting frame, so as to promote the connection column, the shell, the hollow cylindrical body and the drill bit to move in the setting direction as a whole, and cooperate with the rotation of the drill bit to realize the continuous downward drilling of the seabed rock, thereby effectively ensuring the continuity and stability of the drilling operation;

[0039] 17. The present invention can realize the vertical movement of the lifting rod, the connecting plate, the connecting arm, and the mounting plate through the rope, the third pulley block, the second pulley block, the first pulley block, and the winch body, thereby realizing the vertical movement of the support arm and the drill bit, that is, it can accurately meet the use requirements of the drill bit under different working conditions, and ensure that the drill bit can be smoothly lowered to the designated position to carry out the drilling operation when the drilling operation is required, and realize the lifting and hoisting function when the operation is completed or in other necessary circumstances, thereby ensuring the flexibility and operability of the entire equipment in the seabed drilling construction and related operation processes;

[0040] In summary, the present invention has the following beneficial effects:

[0041] The drill bit can be replaced underwater: through the cooperation of the third drive shaft, the connecting plate, the fan-shaped mounting plate, etc., a variety of drill bits can rotate around the third drive shaft and automatically extend downward to align with the limit slide rail. Drill bits of different hardness and shapes can be replaced underwater according to drilling requirements, avoiding the need to lift the rock drill, saving processes and time, and reducing safety hazards and equipment losses;

[0042] Ensure drilling stability: The second drive shaft and other components cooperate to achieve equidistant intermittent operation of the third drive shaft, etc., so that the drill bit and the limit slide rail are accurately aligned and stable, avoiding drilling deviation, reduced efficiency and equipment damage;

[0043] Achieve efficient and uniform dosing: The dosing unit and the drill bit do not interfere with each other, and the dosing can be done directly after drilling, which solves the problem of uneven dosing in traditional hollow tubes. The second hole position corresponds to the first hole position intermittently and is arranged equidistantly to ensure uniform distribution of explosives. When the second hole position corresponds to the first hole position, the explosives are dosed, and when they do not correspond, the explosives can be temporarily stored. Intermittent rotation and stability are achieved through a series of components to ensure uniform dosing and smooth process.

[0044] Ensure drilling continuity and equipment flexibility: The support arm and drill bit are driven to move vertically through relevant components, and drilling is achieved with the drill bit rotating. It can also meet the construction needs of lowering the drill bit for drilling and lifting it up. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] The following is a combination of specific implementation cases and attached Figures 1 to 17 The present invention is further described below, but the present invention is not limited to these embodiments.

[0064] See also Figures 1 to 17 As shown, an underwater drilling and reef blasting equipment comprises a reef blasting ship body 1, which is a reef blasting ship commonly used in the existing market. A plurality of rock drills are arranged on the reef blasting ship body 1, each of which comprises a lifting unit 2, a lifting unit 3, a drilling unit 4, and a drug-feeding unit 5. The drilling unit 4 is used to drill a hole in the rock on the seabed, and the drug-feeding unit 5 is used to feed drugs to the hole after drilling.

[0065] Main references Figures 7 to 12 As shown, the drilling unit 4 includes two connecting columns 4001, and a shell 4002 is fixedly installed between the two connecting columns 4001. A driving assembly is arranged in the shell 4002, and the driving assembly is connected to one end of a first driving shaft 4003. The first driving shaft 4003 is driven to rotate by the driving assembly. The other end of the first driving shaft 4003 extends downward out of the shell 4002 and is connected to a hollow cylindrical body 4008. The rotation of the first driving shaft 4003 realizes the rotation of the hollow cylindrical body 4008. The hollow cylindrical body 4008 is divided into two upper and lower chambers. An intermittent driving mechanism and an intermittent rotating mechanism are respectively arranged in the upper and lower chambers of the hollow cylindrical body 4008. The intermittent driving mechanism causes the intermittent rotating mechanism to realize intermittent rotation, so as to realize the alternating replacement of the drill bit.

[0066] Specific reference Figures 9 to 11 As shown, the intermittent drive mechanism includes a second motor 4009 installed on the top of the inner wall of the hollow cylindrical body 4008, the output end of the second motor 4009 is connected to the second drive shaft 4010, a drive block 4011 is fixedly installed on the second drive shaft 4010, a toggle pin 4012 is installed at one end of the drive block 4011, and an arc-shaped side wall is arranged at the other end of the drive block 4011. The intermittent drive mechanism also includes a turntable 4014 rotatably connected to the inner wall of the hollow cylindrical body 4008 through a bearing, that is, the turntable 4014 can rotate outside Under the action of force, the hollow cylindrical body 4008 rotates along the inner wall, and one end of the third driving shaft 4013 is vertically and fixedly connected to the middle of the turntable 4014. Four sets of fan-shaped frames 4016 are equidistantly arranged on the turntable 4014 along the circumferential direction, and a slideway 4015 is formed between two adjacent fan-shaped frames 4016. A limit block 4017 is installed on each fan-shaped frame 4016, and the arc side wall of the driving block 4011 is rotatably fitted with the inner wall of the limit block 4017; wherein, the toggle pin 4012 is rotatably embedded in the inner cavity of the slideway 4015;

[0067] By turning on the second motor 4009, the second drive shaft 4010 and the drive block 4011 are driven to rotate clockwise. When the push pin 4012 at the drive block 4011 rotates to be embedded in the corresponding inner cavity of the slide 4015, the continuously rotating push pin 4012 can push the slide 4015 to prompt the fan-shaped frame 4016 to rotate 90 degrees clockwise around the third drive shaft 4013. Then the push pin 4012 disengages from the slide 4015, and at the same time, the drive block 4011 is accurately rotated to fit into the side wall of one of the limit blocks 4017, and the limit block 4017 is limited at this time to ensure that the limit block 4017, the turntable 4014, and the third drive shaft 4013 are locked after rotation after 90 degrees.

The above-mentioned existing components will not be limited in model or described in detail here.

[0083] The working principle of an underwater drilling and reef blasting device in this embodiment is as follows:

[0084] When carrying out reef blasting construction, the drilling unit 4 is first placed at the underwater construction position: the winch body 2008 is used to unwind the rope 2009. Since the end of the rope 2009 is connected to the hook 3002, during the unwinding process, the hook 3002 is moved downward by the gravity of the lifting unit 3, the drilling unit 4 and the dosing unit 5, that is, the lifting rod 3001 is moved downward along the first slide groove 2010. At this time, the connecting plate 3003, the connecting arm 3004, the mounting plate 3005, the support arm 3008 and the entire drilling unit 4 at the bottom of the lifting rod 3001 are all moved downward until the drill bit 4024 at the bottom of the drilling unit 4 touches the seabed rock;

[0085] Drilling construction: The first motor 4007 is turned on to drive the second pulley 4005 to rotate, so that the belt 4006 drives the first pulley 4004 and the first drive shaft 4003 to rotate synchronously. At this time, the first drive shaft 4003 drives the hollow cylindrical body 4008 and the drill bit 4024 at the bottom to rotate synchronously with the first drive shaft 4003 as the axis, so that the drill bit 4024 can drill holes on the seabed rocks;

[0086] If it is necessary to replace a different drill bit 4024 according to the seabed rock conditions: the second motor 4009 is turned on to drive the second drive shaft 4010 and the drive block 4011 to rotate clockwise. When the toggle pin 4012 at the drive block 4011 rotates to be embedded in the corresponding slide 4015 inner cavity, the continuously rotating toggle pin 4012 can toggle the slide 4015 to cause the fan-shaped frame 4016 to rotate 90 degrees clockwise around the third drive shaft 4013. Then the toggle pin 4012 is disengaged from the slide 4015, and at the same time, the drive block 4011 is accurately rotated to fit with the side wall of one of the limit blocks 4017. 4017 is limited to ensure that the limit block 4017, the rotating disk 4014 and the third driving shaft 4013 are locked after being rotated 90 degrees; during the clockwise rotation of the third driving shaft 4013, the connecting plate 4018 and the fan-shaped mounting plate 4019 are driven to rotate 90 degrees clockwise synchronously. At this time, the drill bit 4024 at the bottom end of the limit column 4026 rotates 90 degrees clockwise to disengage from the bottom end position of the limit column 4026, and under the elastic force of the spring 4022 there, the top seat 4021, the moving column 4020 and the drill bit 4024 are restored to their initial positions upwards. At the same time, the next group of adjacent moving columns 40 20, the rolling balls 4023 and the drill bit 4024 rotate clockwise to the corresponding limit column 4026, and the rolling balls 4023 are gradually moved along the inner cavity of the limit slide rail 4027 to the bottom end of the limit column 4026. In this process, the rolling balls 4023, the moving column 4020, the light rod 4028 and the drill bit 4024 are gradually moved downward, so that the drill bit 4024 extends downward from the hollow cylindrical body 4008, that is, the drill bit 4024 is replaced. In this process, there is no need to retract the lifting unit 3 and the drilling unit 4 to the main body 1 of the reef blasting ship, and the drill bit 4024 can be replaced in the seabed environment; that is, by clockwise rotation, the lifting unit 3 and the drilling unit 4 are gradually moved downward, so that the lifting unit 3 and the drilling unit 4 can be retracted to the main body 1 of the reef blasting ship, and the drill bit 4024 can be replaced in the seabed environment. The stopper block 4017 and the third drive shaft 4013 rotate 90 degrees, so that the four sets of drill bits 4024 can be replaced alternately in the clockwise direction and extend downward from the outer wall of the hollow cylindrical body 4008, so as to realize the replacement operation of different drill bits 4024; and the position of the drive block 4011 after rotation is stable at the stopper block 4017, so that the third drive shaft 4013 after rotation and the replaced drill bit 4024 can be stable, thereby ensuring that when the first drive shaft 4003 drives the hollow cylindrical body 4008 and the replaced drill bit 4024 to rotate and drill a hole, the three rotate synchronously, and the drill bit 4024 does not have the power to rotate itself;

[0087] Dosing of explosives at the drilled hole positions: In the initial state, the second hole position 5011 does not correspond to the first hole position 5005, and the explosives are placed at the first baffle 5002 through the drug-dosing barrel 5023. The explosives are temporarily stored at the inclined portion 5003, the first baffle 5002, and the second baffle 5004 along the inclined portion 5003. This temporary storage mechanism provides sufficient time for the explosives to be evenly distributed in the inner cavity of the inclined portion 5003, the first baffle 5002, and the second baffle 5004, and effectively prevents the accumulation of more explosives near the drug-dosing barrel 5023. , and the problem of uneven distribution of explosives caused by too little explosives far away from the charging barrel 5023; the third motor 5018 is turned on to drive the fourth driving shaft 5019, the rotating seat 5020, the shifting block 5021, and the limiting plate 5022 to rotate synchronously. When the shifting block 5021 rotates to the meshing gear ring 5014, the continuously rotating shifting block 5021 causes the gear ring 5014 to rotate synchronously by 30 degrees with the shifting block 5021. When the shifting block 5021 rotates to the disengagement position of the gear ring 5014, the limiting plate 5022 rotates to the fitting recessed portion 5016. At this time, the limiting ring 501 5 is limited and no longer rotates, and at this time, the hollow drum 5008 and the second hole 5011 are also limited and no longer rotate, that is, the gear ring 5014 can be intermittently rotated by 30 degrees by rotating the shift block 5021 for one circle, that is, the hollow drum 5008 and the second hole 5011 can be intermittently rotated by 30 degrees, and the six second holes 5011 after rotating by 30 degrees correspond to the positions of the six first holes 5005 to form a drug-feeding channel, and at this time, the explosives in the inner cavity of the first baffle 5002 can be fed into the first baffle 5002 through the six groups of second holes 5011 and the first holes 5005. The explosives are placed in the gap between the hollow rotating drum 5008 and the inner drum 5013, thereby ensuring that the explosives are placed at equal intervals in the circumferential direction of the drilled hole positions; and the interval between two adjacent first hole positions 5005 or two adjacent second hole positions 5011 is 60 degrees, and the angle of each intermittent rotation of the second hole position 5011 is 30 degrees, thereby enabling the second hole position 5011 to correspond to the first hole position 5005 when it rotates once, and to be staggered with the first hole position 5005 when it rotates again, and sufficient time is provided for storing a sufficient amount of explosives when the two are in a staggered state;

[0088] After drilling and charging, the lifting unit 3, the drilling unit 4, and the charging unit 5 are lifted upward to a safe position out of the water by the lifting unit 2. The explosives are conventional reef blasting explosives on the market that can be detonated in an underwater environment. The explosion of the explosives can be remotely controlled to realize the reef blasting construction;

[0089] The present invention can replace the drill bit underwater: through the cooperation of the third drive shaft 4013, the connecting plate 4018, the fan-shaped mounting plate 4019, etc., a variety of drill bits 4024 can rotate circumferentially with the third drive shaft 4013 as the axis, and automatically extend downward to align with the limit slide rail 4027, and the drill bits 4024 with different hardness and shapes can be replaced underwater according to the drilling requirements, avoiding the need to lift the rock drill, saving procedures and time, reducing safety hazards and equipment loss; it can also ensure the stability of drilling: the second drive shaft 4010 and other components cooperate to achieve equidistant intermittent operation of the third drive shaft 4013, etc., so that the drill bit 4024 and the limit slide rail 4027 are accurately corresponding and stable, avoiding drilling deviation, reduced efficiency and equipment damage; it can also achieve Efficient and uniform drug dosing is achieved: the drug dosing unit and the drill bit 4024 do not interfere with each other, and drugs can be directly dosed after drilling, which solves the problem of uneven drug dosing in traditional hollow tubes. The second hole position 5011 and the first hole position 5005 correspond intermittently and are arranged equidistantly to ensure uniform distribution of explosives. Drugs are dosed when the second hole position 5011 corresponds to the first hole position 5005, and the explosives can be temporarily stored when they do not correspond. Intermittent rotation and stability are achieved through a series of components to ensure uniform drug dosing and smooth process; it can also ensure drilling continuity and equipment flexibility: the support arm 3008 and the drill bit 4024 are driven to move vertically through relevant components, and drilling is achieved in conjunction with the self-rotation of the drill bit 4024, which can also meet the construction needs of lowering the drill bit 4024 for drilling and lifting it up.
