Description

Technical Field

[0001] This application relates to the field of hole-opening device technology, and more particularly to hole-opening equipment for oil tanks in sunken ships. Background Technology

[0002] Before salvaging a shipwreck, it is necessary to use a drilling device to open the oil tanks of the shipwreck, and then use an extraction device to extract the fuel from the oil tanks to reduce the weight of the shipwreck so that it can be lifted later.

[0003] The existing drilling device includes a main body, a drilling mechanism, and a propulsion mechanism, wherein the drilling mechanism is slidably mounted on the main body. The propulsion mechanism includes a lead screw and a force-applying handle connected to the lead screw. The lead screw is connected to the drilling mechanism. When the operator turns the force-applying handle, the lead screw rotates, causing it to push the drilling mechanism down into the oil tank, thereby achieving the purpose of drilling.

[0004] In the initial stage of drilling, to prevent the drilling mechanism from shifting or jamming, its downward movement speed should not be too fast. In the middle stage, the drilling mechanism should maintain a steady downward movement speed. In the later stage, the downward movement speed should be slowed down again to reduce the impact on the oil tank. Clearly, throughout the drilling process, the downward movement speed of the drilling mechanism changes according to the progress of the drilling. The existing drilling devices, with their propulsion mechanisms driving the drilling mechanism at a basically uniform downward speed, make it inconvenient for operators to adjust the propulsion speed, resulting in low operability.

[0030] refer to Figure 1 and Figure 2 A preferred embodiment of the shipwreck oil tank opening device according to this application will be described in detail below. The shipwreck oil tank opening device includes a device body 10, a suction and fixing mechanism 20, an opening mechanism 30, and an opening and pushing mechanism 40.

[0031] The device body 10 includes a device main body 11 and a base plate 12, with the base plate 12 connected to the device main body 11.

[0032] The suction mechanism 20 includes a suction body 21, which is mounted on the base plate 12. The suction body 21 is designed to adhere to the oil tank, thereby fixing the wrecked ship oil extraction drilling equipment to the oil tank through the suction effect of the suction body 21, reducing shaking and improving stability during use.

[0033] The perforation and propulsion mechanism 40 is installed on the equipment body 10. The perforation mechanism 30 includes a perforation cutter 31 and a drive component 32. The perforation cutter 31 is connected to the drive component 32, which drives the perforation cutter 31 to rotate. The drive component 32 is also connected to the perforation and propulsion mechanism 40, which drives the drive component 32 to move vertically. Specifically, when the perforation cutter 31 is driven to rotate by the drive component 32, the perforation and propulsion mechanism 40 can drive the perforation cutter 31 to move downward through the drive component 32. That is, while the perforation cutter 31 is cutting the oil tank, the perforation and propulsion mechanism 40 drives the perforation cutter 31 to press down on the oil tank through the drive component 32 to perforate the oil tank.

[0034] Preferably, the suction mechanism 20 includes a plurality of suction bodies 21, which are installed at intervals on the base plate 12 to increase the suction area of ​​the suction body 21 on the oil tank, thereby improving the fixing effect between the opening device for oil extraction from the sunken ship and the oil tank.

[0035] In the first embodiment, the magnetically attached body 21 is fixed to the oil tank by magnetic attraction.

[0036] Preferably, the suction body 21 has an adsorption state and a demagnetization state, and the suction body 21 can switch between the adsorption state and the demagnetization state. In the adsorption state, the suction body 21 is magnetically adsorbed onto the oil tank to achieve fixation; in the demagnetization state, at least the magnetism of the suction body 21 facing the oil tank disappears, and the suction body 21 can be separated from the oil tank to facilitate the movement of the opening equipment for oil extraction from the sunken ship by the staff.

[0037] Preferably, the adsorption body 21 is distributed on the bottom wall of the bottom plate 12 to shorten the distance between the adsorption body 21 and the oil tank, thereby improving the adsorption effect of the adsorption body 21 on the oil tank.

[0038] In one embodiment, the attracting body 21 includes a coil and an electromagnet wound around the coil. Specifically, when the coil is energized, the electromagnet generates magnetism, and the attracting body 21 is in the attracting state. When the coil is de-energized, the electromagnet loses its magnetism, and the attracting body 21 is in the demagnetized state.

[0039] refer to Figure 3 and Figure 4 In another embodiment, the attraction body 21 includes a housing 211, a fixed magnet 212, a movable magnet 213, and at least one rocker arm 214. The housing 211 forms an installation space 21101, in which the fixed magnet 212 and the movable magnet 213 are both installed, with the movable magnet 213 rotatably mounted below the fixed magnet 212. A portion of the rocker arm 214 extends into the installation space 21101 and connects to the movable magnet 213. Thus, by rotating the rocker arm 214, the movable magnet 213 can be rotated, causing the two magnetic poles formed by the movable magnet 213 to sequentially correspond to the downward-facing magnetic poles of the fixed magnet 212.

[0040] Specifically, when the magnetic poles formed by the movable magnet 213 facing the fixed magnet 212 are the same as those formed by the fixed magnet 212 facing the movable magnet 213, a magnetic field is generated at the bottom of the movable magnet 213. At this time, the adsorption body 21 is in an adsorption state and can be adsorbed onto the oil tank. When the movable magnet 213 rotates to a position where the magnetic poles formed by the movable magnet 213 facing the fixed magnet 212 are different from those formed by the fixed magnet 212 facing the movable magnet 213, the magnetic field at the bottom of the movable magnet 213 disappears. At this time, the adsorption body 21 switches to a demagnetized state and can be separated from the oil tank.

[0041] As an example, both the moving magnet 213 and the fixed magnet 212 are implemented as permanent magnets.

[0042] refer to Figure 2 and Figure 3 Furthermore, the suction and holding mechanism 20 also includes a rotation control component 22, the movable magnet 213 is connected to the rotation control component 22, and the rotation control component 22 is used to drive the rocker arm 214 to rotate, thereby driving the movable magnet 213 to rotate.

[0043] In one embodiment, the control component 22 includes an active component 221 and a driven component 222. The active component 221 is mounted on the device body 10, and the driven component 222 is connected to the active component 221. The active component 221 is used to drive the driven component 222 to move. Multiple rockers 214 of the multiple attraction bodies 21 are connected to the driven component 222. When the driven component 222 moves, it drives the multiple rockers 214 to rotate, causing the multiple rockers 214 to drive the multiple moving magnets 213 to rotate, thereby controlling the multiple attraction bodies 21 to switch simultaneously between an attraction state and a demagnetization state.

[0044] As an example, the active component 221 is implemented as a cylinder or hydraulic cylinder.

[0045] In the second embodiment, the suction body 21 is installed on the bottom wall of the base plate 12, and the suction body 21 is fixed to the oil tank by negative pressure adsorption. Specifically, the suction body 21 forms a negative pressure space with its opening facing downwards. The pressure of the negative pressure space formed by the suction body 21 is lower than the external ambient pressure, so that the suction body 21 is tightly adsorbed onto the oil tank.

[0046] As an example, the suction body 21 is implemented to include a suction cup.

[0047] Furthermore, the suction mechanism 20 also includes a negative pressure forming element. The negative pressure space formed by the suction body 21 is connected to the negative pressure forming element through a pipe. The negative pressure forming element extracts gas from the negative pressure space through the pipe to reduce the pressure of the negative pressure space, thereby fixing the suction body 21 to the oil tank under negative pressure. In this embodiment, this device can operate on a ship floating on the water surface to avoid the water flow affecting the suction body 21.

[0048] As an example, the negative pressure forming element is implemented to include a vacuum pump.

[0049] refer to Figure 1 Specifically, the drive component 32 includes a mounting base 321, a drive element 322, and an output shaft 323. The mounting base 321 is connected to the perforation propulsion mechanism 40, and is vertically mounted on the equipment body 11. The drive element 322 is mounted on the mounting base 321. The base plate 12 forms a through hole 1201 corresponding to the gap between adjacent suction bodies 21. The output shaft 323 passes through the through hole 1201. One end of the output shaft 323 extending from the through hole 1201 of the base plate 12 towards the oil tank is connected to the perforation cutter 31, and the other end of the output shaft 323 away from the perforation cutter 31 is connected to the drive element 322. The drive element 322 drives the output shaft 323 to rotate, causing the output shaft 323 to drive the perforation cutter 31 to spin-cut the ship plate.

[0050] In one example, the drive element 322 is implemented to include a hydraulic motor.

[0051] Preferably, the device body 11 forms a guide structure 111 that extends vertically, and the mounting base 321 is slidably mounted on the guide structure 111 formed by the device body 11. The guide structure 111 is used to limit the vertical movement of the mounting base 321 and increase the stability of the mounting base 321 when it moves vertically.

[0052] As an example, the guiding structure 111 is implemented as a guide rod or a guide rail.

[0053] Specifically, the hole-opening and pushing mechanism 40 includes a lead screw 41, which is rotatably mounted on the device body 10, and the axial direction of the lead screw 41 extends vertically. The mounting base 321 is mounted on the lead screw 41, and when the lead screw 41 rotates, the mounting base 321 moves vertically under the constraint of the guide structure 111.

[0054] It is worth mentioning that the device body 10 also includes a top plate 13, which is installed on the side of the device body 11 away from the bottom plate 12. One end of the lead screw 41 away from the bottom plate 12 passes through the top plate 13 and extends to the outside of the top plate 13 away from the bottom plate 12.

[0055] refer to Figures 5 to 7 Preferably, the hole-opening and pushing mechanism 40 further includes a turning component 42, which includes a force-applying handle 421. The force-applying handle 421 is installed at the top of the lead screw 41, and the operator can rotate the force-applying handle 421 to drive the lead screw 41 to rotate.

[0056] Preferably, the rotating component 42 further includes a housing 422 and a first transmission assembly 423, the housing 422 being mounted on the device body 11. The first transmission assembly 423 includes a first rotating component 4231 and a first reducing component 4232. The first reducing component 4232 is sleeved on the belt shifting screw 41, and the first rotating component 4231 is rotatably mounted on the housing 422. A plurality of first transmission teeth 42311 are spaced apart on the outer peripheral wall of the first rotating component 4231, and a plurality of first mating teeth 42321 are spaced apart on the outer peripheral wall of the first reducing component 4232. The first transmission teeth 42311 and the first mating teeth 42321 maintain engagement, thereby the first rotating component 4231 drives the first reducing component 4232 to rotate through the engagement between the first transmission teeth 42311 and the first mating teeth 42321, causing the first reducing component 4232 to drive the belt shifting screw 41 to rotate. It is worth mentioning that the number of first transmission teeth 42311 formed by the first rotating component 4231 is less than the number of first mating teeth 42321 formed by the first speed reducer 4232, and thus the rotational speed of the first speed reducer 4232 is lower than the rotational speed of the first rotating component 4231.

[0057] Furthermore, the first transmission assembly 423 also includes a first handwheel 4233, which is connected to the first drive component 4231. The operator rotates the first handwheel 4233 to drive the first drive component 4231 to rotate. It is understood that the operator can select the first handwheel 4233 and the force application handle 421, matching the operation and propulsion speed, according to the progress of the drilling or the degree of rust in the oil tank, to adjust the propulsion speed.

[0058] In one embodiment, the first rotating element 4231 is implemented as a worm gear; the first reducing element 4232 is implemented as a worm wheel.

[0059] In another embodiment, both the first rotating component 4231 and the first reducing component 4232 are implemented as bevel gears.

[0060] Furthermore, the turning component 42 also includes a second transmission component 424, which is distributed vertically and vertically with the first transmission component 423 to prevent interference between the first transmission component 423 and the second transmission component 424, so as to facilitate operation by the operator.

[0061] Specifically, the second transmission assembly 424 includes a second rotating component 4241 and a second reducing component 4242. The second reducing component 4242 is sleeved on the belt-shifting screw 41, and the second rotating component 4241 is rotatably mounted on the housing 422. The outer peripheral wall of the second rotating component 4241 has a plurality of second transmission teeth 42411 spaced apart, and the outer peripheral wall of the second reducing component 4242 has a plurality of second mating teeth 42421 spaced apart. The second transmission teeth 42411 and the second mating teeth 42421 maintain engagement. The second rotating component 4241 drives the second reducing component 4242 to rotate through the engagement between the second transmission teeth 42411 and the second mating teeth 42421, thereby causing the second reducing component 4242 to drive the belt-shifting screw 41 to rotate. The number of second transmission teeth 42411 formed by the second rotating component 4241 is less than the number of second mating teeth 42421 formed by the second reducing component 4242, resulting in a lower rotational speed of the second reducing component 4242 compared to the second rotating component 4241. Simultaneously, the rotational speed of the lead screw 41 driven by the second transmission assembly 424 is lower than the rotational speed of the lead screw 41 driven by the first transmission assembly 423. In this way, the force-applying handle 421, the first transmission assembly 423, and the second transmission assembly 424 can drive the lead screw 41 to rotate at three different speeds, thereby adjusting the pressure of the drilling tool 31 on the oil tank. This allows the drilling mechanism 30 to perform drilling at three different feed speeds, expanding the range of options available to operators and meeting practical usage needs.

[0062] Furthermore, the second transmission assembly 424 also includes a second handwheel 4243, which is connected to the second belt drive 4241. The operator can rotate the second handwheel 4243 to drive the second belt drive 4241 to rotate.

[0063] In one embodiment, the second rotating member 4241 is implemented as a worm gear; the second reducing member 4242 is implemented as a worm wheel.

[0064] In another embodiment, both the second drive element 4241 and the second reducer 4242 are implemented as bevel gears.

[0065] Preferably, when the first rotating component 4231 and the second rotating component 4241 are both implemented as worm gears of the same type, and the first reducing component 4232 and the second reducing component 4242 are both implemented as worm wheels, the diameter of the second reducing component 4242 is larger than the diameter of the first reducing component 4232, and the number of second mating teeth 42421 formed by the second reducing component 4242 is greater than the number of first mating teeth 42321 formed by the first reducing component 4232, so that the speed at which the second transmission assembly 424 drives the lead screw 41 to rotate is lower than the speed at which the first transmission assembly 423 drives the lead screw 41 to rotate.

[0066] In another embodiment, when the first rotating member 4231 and the second rotating member 4241 are both implemented as worm gears, and the first reducing member 4232 and the second reducing member 4242 are both implemented as worm wheels of the same type, the number of first transmission teeth 42311 formed by the first rotating member 4231 is greater than the number of second transmission teeth 42411 formed by the second rotating member 4241, so that the speed at which the second transmission assembly 424 drives the lead screw 41 to rotate is lower than the speed at which the first transmission assembly 423 drives the lead screw 41 to rotate.

[0067] In summary, when the first rotating component 4231 and the second rotating component 4241 are implemented as worm gears, and the first reducing component 4232 and the second reducing component 4242 are implemented as worm wheels, the diameter of the second reducing component 4242 is larger than the diameter of the first reducing component 4232, and the number of first transmission teeth 42311 formed by the first rotating component 4231 is greater than the number of second transmission teeth 42411 formed by the second rotating component 4241. This also allows the second transmission assembly 424 to drive the lead screw 41 to rotate at a speed lower than the speed at which the first transmission assembly 423 drives the lead screw 41 to rotate.

[0068] Also, preferably, when the first rotating component 4231, the second rotating component 4241, the first reducing component 4232, and the second reducing component 4242 are all implemented as bevel gears, when the first rotating component 4231 and the second rotating component 4241 have the same model, the diameter of the first reducing component 4232 is smaller than that of the second reducing component 4242, and the number of second mating teeth 42421 formed by the second reducing component 4242 is greater than the number of first mating teeth 42321 formed by the first reducing component 4232.

[0069] Alternatively, when the first rotating member 4231, the second rotating member 4241, the first reducing member 4232, and the second reducing member 4242 are all implemented as bevel gears, the first reducing member 4232 and the second reducing member 4242 are of the same type, the diameter of the first rotating member 4231 is larger than the diameter of the second rotating member 4241, and the number of first transmission teeth 42311 formed by the first rotating member 4231 is greater than the number of second transmission teeth 42411 formed by the second rotating member 4241.
