Description

Technical Field

[0001] The invention relates to the technical field of suspended mining boats, in particular to a multifunctional suspended mining boat. Background Art

[0002] Seabed mining is the work of exploiting seabed mineral resources. It mainly collects surface sediments of the seabed at shallow water depths, such as placer, apatite and polymetallic nodules. Seabed mining can promote the development of ocean floor mapping and related technologies. With the advancement of technology, human understanding of the seabed has gradually deepened. Through mining activities, it can further promote the research and development of related fields such as marine geology and marine engineering.

[0003] At present, deep-sea mining vehicles are generally used to carry out seabed mining activities. However, the tracked chassis used by deep-sea mining vehicles are more likely to disturb the seabed, which in turn causes sediment suspension, affects seabed animals and the environment, and causes the formation of bottom plumes, which will cause suffocation and feeding interference problems for seabed animals outside the mining route. At the same time, the long-term suspension of sediments will affect the cleanliness of the water body, interfere with benthic organisms, and lead to a reduction in species types and a decrease in biological abundance.

DETAILED DESCRIPTION

[0030] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0031] See also Figure 1 The present invention provides a multifunctional suspended mining boat, including a casing 1, a balance monitoring device 2, a vertical level control system 3, an ore collection system 4, a sorting and conveying system 5 and a power drive system 6. The casing 1 is provided with the sorting and conveying system 5, and the sorting and conveying system 5 is connected to the ore collection system 4, and the rear side of the casing 1 is connected to the power drive system 6.

[0032] The balance monitoring device 2 is installed along three sides of the outer end of the casing 1, and the structures of the balance monitoring devices 2 on the three sides are consistent. Therefore, through the synchronous monitoring and cooperation of the balance monitoring devices 2 on the three sides, it is possible to efficiently and in real time understand whether the suspended mining boat is in a horizontal state.

[0033] See also Figure 2 The casing 1 in this embodiment includes a shell 11, a water pump cabin 12 installed inside the front side of the shell 11, a semi-enclosed lifting pump cabin 13 located in the middle of the shell 11, so as to ensure the smoothness of the mining process, an air pump cabin 14 located at the rear side of the lifting pump cabin 13, a delivery pump cabin 15 located at the rear side of the air pump cabin 14, a partition 16 installed at the rear side of the shell 11, so as to achieve blocking and waterproofing activities to prevent seawater from invading the rear side of the shell 11, a front water tank 17 opened at the front side of the shell 11, and a rear water tank 18 opened at the rear side of the shell 11. Thus, through the cooperation of the front water tank 17 and the rear water tank 18, the suspended mining boat can be adjusted and suspended in a horizontal state to ensure a stable horizontal collection state.

[0034] The water pump cabin 12, the lifting pump cabin 13, the air pump cabin 14 and the delivery pump cabin 15 are all sealed, so that the parts installed inside can be ensured to operate stably and not easily damaged by water ingress. In this way, the key components of the suspended mining boat can be located in the sealed cabin, which reduces the failure rate, thereby reducing the equipment maintenance cost and improving the collection efficiency and economic benefits.

[0035] See also Figure 3-5 The vertical level control system 3 in this embodiment includes a water pump 31 installed in the water pump cabin 12 for adjusting the level of the suspended mining boat, a first water check valve 32 installed in the front side of the shell 11 and connected to the water pump 31, so that the water inlet and outlet of the front water cabin 17 can be adjusted through the first water check valve 32 to meet the subsequent horizontal adjustment of the suspended mining boat, a first gas tank 33 installed in the front side of the shell 11, and a pressure monitoring device 34 installed in the lower end of the shell 11, so as to monitor the distance between the ore picking wheel 41 and the seabed through the pressure monitoring device 34. The air pump 35 is installed in the air pump cabin 14, and the second water check return valve 36 is arranged at the lower end of the rear side of the shell 11 and connected to the air pump 35. The water inlet and outlet of the rear water tank 18 can be flexibly adjusted through the second water check return valve 36 to meet the subsequent horizontal adjustment activities of the suspended mining boat. The second air tank 37 is installed in the rear side of the shell 11, and the second air tank 37 and the first air tank 33 can cooperate with the air pump 35 to realize the vertical adjustment activities of the suspended mining boat. The motor 38 is arranged at the rear side of the casing 1 and connected to the middle part of the rear side of the partition 16.

[0036] The pressure monitoring device 34 is connected to the middle of the ore collecting wheel 41 and is installed at the middle end of the ore collecting cover 42, so that the distance between the ore collecting wheel 41 and the seabed can be flexibly monitored in real time.

[0037] Specifically, the distance between the ore collection system 4 and the seabed can be monitored by the pressure monitoring device 34, and the monitored signal is transmitted to the water pump 31 and the air pump 35. That is, when the distance between the ore collection system 4 and the seabed is too small, the gas inside the first gas tank 33 and the second gas tank 37 can be pressed into the front water tank 17 and the rear water tank 18 respectively through the operation of the air pump 35, so that the front water tank 17 and the rear water tank 18 can be drained, thereby enabling the floating mining boat to perform an upward adjustment activity as a whole;

[0038] When the distance is too large, the gas inside the front water tank 17 and the rear water tank 18 can be pressed into the first gas tank 33 and the second gas tank 37, so that the front water tank 17 and the rear water tank 18 can respectively realize external water absorption through the cooperation of the first water check valve 32 and the second water check valve 36, so that the floating mining boat can perform the descending adjustment activity as a whole;

[0039] When the distance is moderate, the air-water ratio inside the front water tank 17 and the rear water tank 18 remains unchanged, ensuring a stable suspension effect;

[0040] The balance monitoring device 2 installed on the three sides of the outer end of the casing 1 can monitor in real time whether the suspended mining boat is in a horizontal state, and can transmit a signal to the motor 38. In this way, the motor 38 will drive the water pump 31 to adjust the water volume of the front water tank 17 and the rear water tank 18, so as to achieve the front and rear horizontal adjustment of the suspended mining boat, so that the suspended mining boat can achieve stable vertical adjustment and can also be in a stable horizontal collection state, so as to achieve suspended mining activities, reduce the contact with the seabed during the mining process, and achieve low disturbance to the seabed.

[0041] The ore collection system 4 includes an ore picking wheel 41 connected to the inside of the lower end of the casing 1, and the outer ore picking end of the ore picking wheel 41 is arranged in a needle shape as a whole, so as to ensure that the impact on the seabed is reduced when collecting ore, and at the same time, reduce the operating energy consumption. An ore collecting cover 42 for ore collection and transmission is integrated at the lower end of the casing 1, and a lifting pump 43 is installed in the lifting pump cabin 13. In this way, it can be ensured that the ore entering the upper end of the ore collecting cover 42 can realize the sorting and transportation coordination activities.

[0042] Specifically, when the suspended mining boat moves forward, the forward power can be used to realize the rotation of the ore-collecting wheel 41 installed inside the ore-collecting cover 42, so that the ore-collecting wheel 41 can rotate to realize the collection of seabed ore, and cooperate with the ore-collecting cover 42 to realize the ore lifting activity, and the ore is lifted to the position of the lifting pump 43, and the lifting pump 43 can transfer the ore to the inside of the sorting and conveying system 5 through the hydraulic action;

[0043] Since the ore picking wheel 41 is a needle-shaped ore picking wheel as a whole, its impact on the seabed can be reduced to a minimum, while reducing the operating energy consumption.

[0044] The sorting and conveying system 5 includes a feed channel 51 opened in the shell 11 and connected to the ore collecting cover 42, so that the collected ore can be transmitted to realize screening and crushing reinforcement processing and collection activities, a screen 52 installed at the upper end of the feed channel 51 for ore screening, a double-toothed roller crusher 53 installed at the rear side of the upper end of the feed channel 51 and can be used for crushing larger diameter ores, a one-way valve 54 arranged at the lower end of the double-toothed roller crusher 53, so that the ore can be prevented from falling out and collected, an inclined plate 55 for guiding smaller diameter ores arranged at the lower end of one side of the one-way valve 54, an ore collecting chamber 56 for collecting and exporting ore arranged at the other side of the one-way valve 54, and a conveying pump 57 installed in the conveying pump cabin 15 and connected to the inside of the ore collecting chamber 56, so that the collected ore can be pushed out by the hydraulic force of the conveying pump 57 and connected to the conveying pipeline 58 extending from the upper end of the ore collecting chamber 56 to the outside of the shell 11.

[0045] Among them, the bottom of the ore collecting cover 42 is set in an open shape, and the rear part of the ore collecting cover 42 is set in a semi-arc plate shape, and the rear half of the ore collecting cover 42 is connected with the feed channel 51, ensuring the efficient combination of the ore collecting cover 42 and the feed channel 51, and realizing the collection and sorting activities of seabed ore; a small ore screening space is formed between the screen 52, the one-way valve 54 and the inclined plate 55, so that the collected ore can be sorted and screened; the bottom position of the one-way valve 54 is higher than the bottom of the ore collecting chamber 56, and the bottom of the ore collecting chamber 56 is connected to the conveying pump 57, ensuring that the ore collecting chamber 56 cooperates with the conveying pump 57 set at the bottom to realize the rapid discharge of the collected ore.

[0046] Specifically, when the lifting pump 43 hydraulically transfers the ore to the inside of the feed channel 51, the ore can be pre-contacted with the screen 52 along the feed channel 51, so that the screening can be carried out to screen the size of the ore. The ore with a smaller diameter can fall to the upper end of the inclined plate 55 and slide down along the inclined plate 55, while the ore with a larger diameter can fall into the double-toothed roller crusher 53, so that the double-toothed roller crusher 53 crushes the ore with a larger diameter, thereby reducing the diameter of the ore, and it also falls to the upper end of the inclined plate 55 to slide down, and the ore at the upper end of the inclined plate 55 can enter the inside of the ore collecting chamber 56 through the opened one-way valve 54, and the ore in the ore collecting chamber 56 can be hydraulically transferred to the inside of the conveying pipe 58 by the conveying pump 57, and then transferred to the external collection point through the conveying pipe 58, thereby conveniently completing the seabed ore screening and crushing collection activities.

[0047] The power drive system 6 includes a rudder 61 installed on the four sides of the rear end of the casing 1 and used for floating the mining boat to move and turn, and a propeller 62 docked at the rear side of the casing 1 and capable of rotating with the motor 38 to propel the boat forward.

[0048] Among them, the tail rudders 61 are installed correspondingly along the four corners of the rear side of the casing 1, and the four side tail rudders 61 are connected to the motor 38 through gears. Therefore, when the transmission gear of the motor 38 rotates, the angles of the tail rudders 61 set on the four sides can be flexibly adjusted to meet the convenient steering activities of the suspended mining boat.

[0049] Specifically, the motor 38 can drive the propeller 62 to rotate to push the floating mining boat forward. At the same time, the motor 38 can control the tail rudders 61 arranged on the four sides to rotate through gears, so as to adjust the driving direction of the floating mining boat.
