Description

[0001] The present application is a divisional application of the patent application No. 202410435844.2, with the application date of April 11, 2024, and the title of “A deep-sea mining buoyancy transportation device”. TECHNICAL FIELD

[0002] The present application belongs to the technical field of deep-sea mining equipment, and specifically relates to a deep-sea mining buoyancy transportation device. BACKGROUND

[0003] The seabed is rich in a large amount of manganese nodules, polymetallic sulfides, cobalt-rich nodules and other mineral resources, as well as a large amount of rare metals. The development of seabed mineral resources has become an important force to support the future economic, industrial and technological development.

[0004] Deep-sea mining generally takes a surface mother ship as a support platform of the system. Under the pipe ship connecting device at the bottom of the ship, a slurry lifting riser is connected until a few hundred meters away from the seabed. The top end of the lifting riser is connected with the pipe ship connecting device, and the bottom end of the lifting riser is connected with a lifting pump set, a hose and a seabed mining car, etc. The mining car operates on the seabed, and the collected slurry is transported to the inlet of the lifting pump set by the material pump through the hose, and then the slurry is transported to the surface mother ship by the lifting pump set through the lifting riser.

[0005] Since the slurry contains a large amount of seabed slurry, these seabed slurry are transported to the mother ship together with the ore by the material pump and the lifting pump. Since the seabed slurry has a complex composition and a high salt content, once it enters commercial mining, a large amount of seabed slurry will be piled on land, which will cause serious environmental pollution to the land.

[0006] In addition, the seabed slurry also contains some larger mineral nodules. On the one hand, due to the limitation of the diameter of the slurry lifting pipeline, especially large mineral nodules cannot be loaded. On the other hand, the material pump and the lifting pump generally use centrifugal pumps or plunger pumps. Due to the limitation of the function of the delivery pump, the large mineral nodules will cause serious wear and deformation of the main parts of the centrifugal pump and the plunger pump when passing through the centrifugal pump and the plunger pump, thereby causing the failure of the centrifugal pump and the plunger pump. Therefore, the large ore cannot be transported to the mother ship by the pipeline transportation method, and will be discarded on the seabed, causing waste of seabed mineral resources.

[0007] To solve the above problems, the patent application name: a deep-sea buoyancy mining system, application number: 202311790279.3, through the float ball uses two hangers, respectively hoisting backfill box and ore box, and a self-control hook is arranged between the hanger and the backfill box, the backfill box filled with seabed mud is sunk to the mining area by using its weight exceeding the buoyancy of the float ball, after the backfill box is bottomed, the ore box is suspended, by filling the ore box with large ore, as the weight of the ore box increases, the pulling force of the float ball on the backfill box decreases, when the pulling force decreases to a certain amount, the self-control hook is automatically unhooked, the backfill box is left on the seabed, and the float ball with the ore box automatically floats up.

[0008] Because the self-control hook is a scissors structure, a compression spring is arranged between the two handles of the upper part of the scissors, the two handles of the upper part of the scissors are separated, the lower blade of the self-control hook is always open, the clamping force generated by the upward pulling force of the float ball between the two handles of the upper part of the scissors overcomes the counterforce of the compression spring, the lower blade of the scissors is closed, and the lifting hole formed by the closed blade suspends the lifting rope of the backfill box; therefore, when it is necessary to hang the lifting rope of the backfill box in the lifting hole of the self-control hook, it is necessary to first apply an external clamping force to the upper part of the scissors structure to make the blade close to form a lifting hole, when the float ball lifts the backfill box and generates a clamping force on the two handles of the upper part of the scissors of the self-control hook, the clamping force overcomes the spring force of the compression spring, and the blade is closed, and then the external applied external force is removed, so that the self-control hook can be automatically unhooked on the seabed, and the operation is relatively complicated. Once the operation is failed and the self-control hook is forgotten to be removed, the automatic structure device of the self-control hook will be invalid.

[0009] That is to say, in the current deep-sea mining buoyancy transportation system, the self-control hook hooking process is relatively complicated, and once the operation is failed, the automatic structure of the self-control hook is easily invalid. SUMMARY

[0010] The purpose of the present application is to overcome the problem that the self-control hook hooking process in the existing deep-sea mining buoyancy transportation device is relatively complicated, and once the operation is failed, the automatic structure of the self-control hook is invalid; and to invent a deep-sea mining buoyancy transportation device to make up for the shortcomings of the existing deep-sea mining transportation device.

[0025] The upper end of the adjusting screw is provided with a compression spring guide journal, and the thread of the adjusting screw is matched with the thread arranged in the inner thread of the damper hole.

[0026] Beneficial effects

[0027] The deep-sea underwater transportation system composed of the floating ball, the backfill box, the mineral box and the self-control hook is used, when the floating ball sinks into the sea together with the backfill box and the unloaded mineral box, the bottom of the backfill box is lower than the bottom of the mineral box by h meters (h is about 0.5 meters, if the value is too large, it is inconvenient to fill the mineral in the mineral box on the seabed, and if the value is too small, the bottom of the mineral box is easy to contact the seabed), and the mineral box is suspended in the water under the influence of the buoyancy of the floating ball.

[0028] After the backfill box is seated on the bottom, the mineral box is loaded with ores by the remote control seabed mine car, and in the process of loading the mineral, the mineral box is always floating in the sea under the traction of the floating ball. Since the length of the control rod is greater than the vertical distance between the first hoist and the second hoist, and the second hoist and the first hoist always keep clamping force on the control rod through the self-control hook, that is, even if the self-control hook has released the backfill box hoisting rope, the second hoist and the self-control hook still exert clamping force on the control rod. Since the self-control hook is subjected to the reaction force of the control rod, which is the thrust on the push rod shaft of the self-control hook, as the loading amount of the mineral box increases, the traction force of the floating ball on the second hoist increases, according to the decomposition of force, the clamping force on the control rod also increases synchronously, when the load of the mineral box reaches the rated load, the reaction force of the control rod on the push rod shaft is greater than the friction between the push rod shaft and the damper and the push rod hole, the push rod shaft on the self-control hook is pulled out to the left by the control rod; since the hoisting rope on the backfill box is hung on the push rod shaft, the push rod shaft is pulled out of the push rod hole L2 length, the backfill box hoisting rope falls off the push rod shaft, that is, the backfill box and the floating ball are released from the constraint and stay on the seabed; at the same time, the floating ball loses the constraint of the backfill box and immediately floats up with the mineral box until the sea surface, and then the mineral box is lifted to the mother ship by the material crane on the mother ship; at the same time, the seabed mine car also stops loading the ores.

[0029] The automatic unloading function of the self-control hook under the first hoist of the backfill box not only can release the backfill box from the constraint of the floating ball and stay on the seabed, but also can automatically limit the loading amount of the ores in the mineral box, so as to avoid the problem that the mineral box cannot float up due to overloading.

[0030] In order to accurately set the rated loading ore amount of the ore bin, the automatic control hook will be automatically unhooked. The adjusting screw of the damper is used to adjust the compression amount of the compression spring. According to the fact that the compression amount of the compression spring is proportional to the pressure, the damper block is pressed by the compression spring, the friction force of the damper block on the push rod shaft is accurately set, and the automatic control hook can be automatically unhooked when the ore bin reaches the rated loading ore amount. In order to ensure the reliability of the damper, the positioning shaft necks of the compression spring are arranged at the lower end of the damper block and the upper end of the adjusting screw, so that the damper block, the compression spring and the adjusting screw can be kept concentric. In addition, due to the large deformation amount of the compression spring, the damper has a strong self-compensation function, and the friction force of the damper on the push rod shaft is prevented from being reduced too much due to the wear of the damper block.

[0031] In order to make the control rod be able to quickly unhook the automatic control hook, that is, to quickly pull out the push rod shaft from the push rod hole to the left, the left side surface of the push rod pin and the left side plate is used to limit the length of the push rod shaft inserted into the push rod hole, and the push rod shaft is arranged as a tapered shaft on the right side of the left side plate, and the taper direction is that the left diameter is larger and the right diameter is smaller. In order to prevent the control rod and the push rod shaft from being separated from the ∩-shaped frame after the filling box hoisting rope is released, the length L1 of the fork head is set to be equal to the length L2 of the push rod shaft.

[0032] The buoyancy transportation device for deep-sea mining disclosed by the application uses the gravity of the backfilling box filled with seabed mud to bring the floating ball into the seabed, and then uses the mechanical automatic unloading device, that is, the automatic control hook, to automatically unload the backfilling box by loading the ore bin and changing the force of the control rod on the automatic control hook, so that the ore bin is automatically floated to the sea surface, and green mining is realized.

The buoy 14 is symmetrically equipped with two lifting lugs on its upper and lower sides. The cable car 11 uses a cable 13 to traction and control the upper left and right lifting lugs of the buoy 14. The buoy 14 is suspended from the backfill box 20 by the lower left lifting lug, the first lifting device 18, and the self-control hook 50. The buoy 14 is suspended from the ore box 17 by the lower right lifting lug and the second lifting device 15 by the ore box 17. The first lifting device 18 is hinged to the left lifting lug of the buoy 14, and the second lifting device 15 is hinged to the right lifting lug of the buoy 14. A horizontal hinge is used to connect the self-control hook 50 and the second lifting device 15 using a control rod 60. The length of the control rod 60 is greater than the vertical distance between the first lifting device 18 and the second lifting device 15, so that the first lifting device 18 always maintains a clamping force on the control rod 60 through the self-control hook 50 and the second lifting device 15. That is to say, even if the self-control hook 50 has released the backfill box lifting rope 19, the second lifting device 15 and the self-control hook 50 are still applying a clamping force to the control rod 60.

[0056] The first lifting device 18 and the second lifting device 15 are cables, anchor chains, or rigid rods; in this embodiment, the first lifting device 18 and the second lifting device 15 are cables.

[0057] Before the self-controlled hook 50 is lowered into the sea, first loosen the adjusting screw 513 of the damper 51, then place the backfill box hoisting rope 19 into the U-shaped frame 500 of the self-controlled hook 50, so that the backfill box hoisting rope 19 is above the push rod shaft 505. Insert the push rod shaft 505 into the push rod hole 503 from left to right until the push rod pin touches the left side of the left side plate 501. Then, tighten the adjusting screw 513 to ensure that its tightening torque is the same as the set value.

[0058] When the backfilling box 20 is lowered into the sea, it is filled with seabed slurry and its weight exceeds the maximum upward carrying capacity of the buoy 14 in the sea, and the ore box 17 is empty; on the mother ship 10, the marine underwater transport device composed of the buoy 14, the backfilling box 20, the ore box 17 and the like is lowered into the sea by the material hoist 12, and the lowering position of the buoy 14 is controlled by the cable car 11 and the cable 13 on the mother ship 10; under the gravity traction of the backfilling box 20 and the like, the buoy 14 is lowered to the designated seabed position, and when the backfilling box 20 is seated on the seabed, the bottom of the ore box 17 is about 0.5 meters higher than the bottom of the backfilling box 20, so that the ore box 17 is suspended in the water.

[0059] The backfilling box 20 is a one-time fully enclosed box, that is, each backfilling box 20 is used only once, and in order to avoid pollution of the marine environment, the backfilling box 20 is made of a material that can be naturally degraded and is pollution-free, such as a wooden box, an iron box or a paperboard box.

[0060] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The self-control hook 50 is provided with a ∩-shaped frame 500, the top of the ∩-shaped frame 500 is provided with a connecting hole 507, and the connecting hole 507 is connected with the first lifting appliance 18. The lower part of the ∩-shaped frame 500 is provided with a push rod hole 503 penetrating through the left side plate 501 and the right side plate 502, and the push rod hole 503 on the left side plate 501 and the right side plate 502 is concentric, and the push rod shaft 505 is inserted into the push rod hole 503 on the left side plate 501 and the right side plate of the ∩-shaped frame 500; the backfilling box hoisting rope 19 is hung on the push rod shaft 505 between the left side plate and the right side plate of the ∩-shaped frame 500; the left end of the push rod shaft 505 is provided with a push rod pin hole outside the ∩-shaped frame 500, and the push rod pin hole is provided with a push rod pin 506, and the push rod pin 506 is hingedly connected with the left end of the control rod 60.

[0061] In order to enable the control rod 60 to quickly pull the push rod shaft 505 out of the push rod hole 503 to the left, the push rod pin 506 and the left side of the left side plate 501 are used to limit the length of the push rod shaft 505 inserted into the push rod hole 503, and the push rod shaft 505 is arranged as a tapered shaft on the right side of the left side plate 501 of the ∩-shaped frame 500, and the taper direction is that the left diameter is large and the right diameter is small.

[0062] The control rod 60 comprises a long rod 601 and a fork head 602, the left end of the long rod 601 and the right end of the fork head 602 are fixedly connected by a nut 603, the fork head 602 is similar to a tuning fork and penetrates up and down, the fork mouth is to the left, and a pair of connecting holes are arranged on the front and rear side plates at the port of the fork mouth and are hingedly connected with the push rod pin 506; the right end of the long rod 601 is hingedly connected with the second lifting appliance 15, and the control rod 60 is kept horizontal during work; the length of the long rod 601 is set by experiment in cooperation with the damper.

[0063] In order to avoid the release of push rod shaft 505 backfill box hoisting rope 19, and ∩-shaped frame 500, the present application will be the maximum horizontal movement length L1 set with push rod shaft 505 L2 length equal to; thus, both to ensure that the control lever 60 and push rod shaft 505 off ∩-shaped frame 500, but also enable backfill box hoisting rope 19 can be reliable drop.

[0064] The purpose of the damper 51 is to set the rated load of the mineral aggregate box 17; mineral aggregate box 17 reaches the rated load, the automatic control hook 50 will be automatically unhooked. Damper 51: contains in the left side plate 501 bottom center, set a with push rod hole 503 perpendicular intersection of damper hole 504, damper hole 504 is a threaded hole, in the damper hole 504, from top to bottom, are provided with damping block 511, compression spring 512, adjusting screw 513; damping block 511 is made of rubber, the upper end is provided with a circular arc with the outer diameter of push rod shaft 505 adapt, the lower end is provided with a stepped journal, the stepped journal provides a positioning for compression spring 512, adjusting screw 513 with the internal thread in the damper hole 504, adjusting screw 513 is also provided with a stepped journal, for compression spring 512 provides a positioning, to ensure that the adjusting screw 513, compression spring 512, damping block 511 coaxial line. According to Hooke's law, the compression of the compression spring is proportional to the pressure, the damper 51 by adjusting screw 513 on the compression spring 512 compression force size is accurately set, so as to accurately set the damping block 511 on the push rod shaft 505 friction, so as to accurately set the floating ball 14 of the floating condition; in addition, due to the large deformation of compression spring 512, has strong self-compensation function, to avoid the wear of damping block 511, the damper 51 on the push rod shaft 505 friction drop too large, so as to affect the setting of the rated load of the mineral aggregate box 17.

[0065] As Figure 1 , Figure 2 , Figure 4 , Figure 5The working process of the self-control hook 50 is shown. When the backfill box 20 is on the seabed in the deep sea, the ore box 17 is loaded with ore by the remote-controlled seabed mining car, and during the entire loading process, the ore box 17 floats in the seawater under the traction of the floating ball 14. Since the second lifting device 15 and the self-control hook 50 can always keep the clamping force on the control rod 60, the self-control hook 50 is subjected to the reaction force of the control rod 60, that is, the push rod shaft 505 of the self-control hook 50 is subjected to the reaction force of the fork head 602 of the control rod 60. As the ore loaded in the ore box 17 increases, the traction force of the floating ball 14 on the second lifting device 15 increases, and according to force decomposition, the clamping force between the control rod 60 and the self-control hook 50 also increases. When the load of the ore box 17 reaches the rated load, the reaction force of the control rod 60 on the push rod shaft 505 is greater than the friction force between the push rod shaft 505 and the damper 51 and the push rod hole 503, so that the push rod shaft 505 of the self-control hook 50 is pulled out to the left by the control rod 60. Since the push rod shaft 505 penetrates the push rod hole 503 of the left and right side plates of the ∩-shaped frame 500, the backfill box hoisting rope 19 is suspended on the push rod shaft 505 between the left and right side plates of the ∩-shaped frame 500. After the push rod shaft 505 is pulled out of the ∩-shaped frame 500, the backfill box hoisting rope 19 falls off the self-control hook 50, and the backfill box 20 is released from the constraint of the floating ball 14 and stays on the seabed. At the same time, the floating ball 14 loses the constraint of the backfill box 20 and takes the ore box 17 with it to float up to the sea surface, and then the material hoist 12 on the sea surface mother ship 10 is used to unload the ore in the ore box 17 onto the mother ship 10. At the same time that the ore box 17 floats up, the seabed mining car stops loading.

[0072] The front damping block 524 and the rear damping block 525 are made of rubber. On the one hand, rubber has strong friction and a strong damping effect. On the other hand, rubber is elastic, which prevents the front damping block 524 and the rear damping block 525 from seizing with the push rod shaft 505, thus preventing the push rod shaft 505 from being properly disengaged.

[0073] The second damper 52 is positioned laterally on the push rod shaft 505. A threaded pair is formed by the second adjusting screw 521 and the round nut 527, ensuring that the front damping block 524 and the rear damping block 525 exert equal but opposite lateral pressures on the push rod shaft 505, thus reducing the radial force on the push rod shaft 505. Furthermore, the use of the front and rear damping blocks 524 and 525 increases the contact area with the push rod shaft 505, enhancing the damping effect. An axial gap of δ = 3 mm is provided between the front and rear damping blocks 524 and 525 to prevent interference after axial deformation.

[0074] The spring 522 is arranged between the second adjusting screw 521 and the cushion block 523, and has the following purposes: on the one hand, it is used to accurately adjust the lateral pressing force of the front damping block 524 and the rear damping block 525 on the push rod shaft 505, so as to accurately set the damping size of the second damper 52 on the push rod shaft 505; on the other hand, it is used to automatically compensate the wear amount of the front damping block 524 and the rear damping block 525, and improve the reliability of the second damper 52.

[0075] The outer circle of the round nut 527 is provided with a long groove in the axial direction, and cooperates with the anti-rotation screw 526 arranged at the lower bottom of the second left side plate 801, so that the round nut 527 not only can be prevented from rotating in the second damper hole 804, but also can be prevented from sliding out of the second damper hole 804, and plays a safety protection role.

[0081] The third damper is selected from a damper or a second damper.

[0082] The other parts are the same as those in Embodiment 1 and Embodiment 2.

[0083] As Figure 9 ,Figure 10 、 Figure 11 As shown in FIG. 2, the length of the second control rod 70 is less than the vertical distance between the first lifting tool 18 and the second lifting tool 15, so that the second lifting tool 15 and the first lifting tool 18 always keep pulling force on the second control rod 70 through the third self-control hook 90, even if the third self-control hook 90 releases the backfill box hoisting rope 19, the second lifting tool 15 and the first lifting tool 18 still apply pulling force on the second control rod 70 through the third self-control hook 90.

[0084] The third self-control hook 90 comprises a third ∩-shaped frame 900, the lower part of the third ∩-shaped frame 900 is provided with a third push rod hole 903 penetrating through a third left side plate 901 and a third right side plate 902, the left end of the second control rod 70 is inserted into the third push rod hole 903 of the third left side plate 901 and the third right side plate 902; the second control rod 70 is provided with a taper on the left side of the third right side plate 902, the taper direction is: the right diameter is large, and the left diameter is small; the backfill box hoisting rope 19 is hung on the second control rod 70 between the third left side plate 901 and the third right side plate 902; the second control rod 70 is fixedly connected with a push rod pin 506 on the right side of the third right side plate 902; a limiting frame 905 is fixedly connected on the right side of the third right side plate 902, and L3 and L4 are equidistant; a third damper for increasing the friction of the second control rod 70 is arranged below the third push rod hole 903 of the third right side plate 902; the third damper is selected from the damper 51 or the second damper 52; the second lifting tool 15 is hingedly connected with the right end of the second control rod 70.

[0085] In order to enable the third self-control hook 90 to quickly release the backfill box hoisting rope 19 after the mineral aggregate box 17 reaches the rated loading capacity, the second control rod 70 is provided with a taper on the left side of the third right side plate 902, the taper direction is: the left diameter is small, and the right diameter is large, since the second control rod 70 is pulled out of the third push rod hole 903 from left to right to release the backfill box hoisting rope 19, therefore, the third damper loses the damping effect after the diameter of the second control rod 70 becomes small, so that the second control rod 70 can be quickly pulled out to the right, and the third self-control hook 90 automatically releases the backfill box hoisting rope 19.

[0086] In order to avoid that the second control rod 70 is separated from the third self-control hook 90 after the third self-control hook 90 is automatically released, and the second control rod 70 is excessively sent out to the left in the third push rod hole 903, affecting the response speed of the third self-control hook 90, the limiting frame 905 and the push rod pin 506 are arranged on the right side of the third right side plate 902, and L3 and L4 are equidistant, so that the left and right movement distances of the second control rod 70 are limited by the limiting frame 905 and the push rod pin 506.
