Technical Field

[0001] The present invention relates to the technical field of offshore mining equipment, and in particular to a wave compensation device and method for an offshore mining ship. Background Art

[0002] As an important resource development method, offshore mining is of great significance to the acquisition of global mineral resources. However, the complexity and uncertainty of the offshore operating environment, especially the constant changes in ocean waves, poses a huge challenge to the stability and operating efficiency of offshore mining ships. Traditional offshore mining ships often find it difficult to effectively cope with violent wave motions, which not only affects the operating efficiency of mining equipment, but may also cause damage to the hull structure and even cause safety accidents.

[0003] In order to solve these problems, engineers have been exploring various wave compensation technologies. Early wave compensation devices mainly relied on the design of the hull 1 and the fixed configuration of the onboard equipment. Although these methods can reduce the impact of waves on the hull 1 to a certain extent, they have limited adaptability and flexibility and are difficult to cope with complex and changeable sea conditions.

[0004] The existing wave compensation technology still has some limitations, such as slow response speed, low adjustment accuracy, high maintenance cost, etc. Therefore, developing a new wave compensation device that can respond to ocean wave changes quickly, accurately and economically is of great practical significance for improving the operating performance and safety of offshore mining vessels.

[0015] In a preferred embodiment of the present invention, a buffer plate is fixedly connected to one side of the movable rod, and a plurality of through slots are formed on one side of the buffer plate.

[0016] In a preferred embodiment of the present invention, a plurality of the buffer components are distributed along the outer side of the hull.

[0017] In a preferred embodiment of the present invention, the following steps are included:

[0018] S1: The wave direction sensing unit is activated to detect waves and collect data;

[0019] S2: The automatic adjustment filling unit receives the wave data and automatically adjusts the filling material in the filling box;

[0020] S3: The balance unit senses the tilt of the hull and adjusts the amount of water in the pumping box to keep the hull level;

[0021] S4: When the waves weaken, the rapid discharge unit discharges the water in the filling and pumping box to adjust the balance of the hull;

[0022] S5: When the operation is completed or balancing is not required, turn off the power supply of the heave compensation mechanism to ensure that all filling and pumping boxes are safely discharged.

[0023] In a preferred embodiment of the present invention, in S1, the wave direction sensing unit is responsible for real-time monitoring of the dynamics of ocean waves, including the direction and intensity of the waves, and the sensed data is then transmitted to the automatic adjustment filling unit to provide key information for subsequent filling material adjustment.

[0024] In a preferred embodiment of the present invention, in S2, the automatic regulating filling unit automatically adjusts the flow direction and amount of the filling in the filling box, and the automatic regulating filling unit intelligently distributes the filling to adapt to the changing wave conditions, thereby maintaining the stability of the hull.

[0025] In a preferred embodiment of the present invention, in S3, the balancing unit automatically adjusts the amount of water filled in the filling and pumping box on the left or right side of the hull by sensing the tilt of the hull to offset the tilt of the hull.

[0028] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0029] (1) The present invention provides a wave compensation device and method for an offshore mining vessel. By integrating a wave direction sensing unit, an automatic adjustment filling unit, a balancing unit and a rapid discharge unit, effective control of the hull tilt is achieved. The wave direction sensing unit can monitor the dynamics of ocean waves in real time. The automatic adjustment filling unit intelligently adjusts the flow direction and amount of the filler according to the wave data. The balancing unit automatically adjusts the water volume to offset the hull tilt.

[0038] The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0039] like Figure 2 and Figure 4 As shown, a wave compensation device for an offshore mining ship comprises: a hull 1, a wave compensation mechanism 2 arranged on the inner wall of the bottom of the hull 1, two filling and pumping boxes 3 arranged on both sides of the wave compensation mechanism 2, and a plurality of buffer components 4 arranged on the outer wall of the hull 1;

[0040] Two filling and pumping boxes 3 are respectively distributed on both sides of the bottom inner wall of the hull 1;

[0041] The wave compensation mechanism 2 includes: a wave direction sensing unit, an automatic adjustment filling unit, a balancing unit, and a rapid discharge unit;

[0042] Sensing wave direction unit, used to detect the dynamics of waves in the ocean;

[0043] Automatically adjusting the filling unit: used to receive data from the wave sensor and automatically adjust the flow direction and amount of the filling material in the filling box 3 according to the data to adapt to the changes in the waves;

[0044] The balancing unit is used to sense the tilt of the hull 1 and automatically adjust the amount of water in the filling and pumping box 3 to offset the tilt of the hull 1 and keep the hull 1 in a horizontal state;

[0045] The rapid discharge unit can be immediately started to discharge water or other substances in the filling and pumping box 3 when the influence of waves weakens and the hull 1 needs to be adjusted to adapt to new sea conditions.

[0046] The buffer assembly 4 includes a fixed column 401, a movable groove 403 is provided in the fixed column 401, a movable rod 402 is slidably connected in the movable groove 403, a spring 404 is fixedly connected to one side of the movable rod 402, and the other end of the spring 404 is fixedly connected to the inner wall of one side of the movable groove 403.

[0047] A buffer plate 5 is fixedly connected to one side of the movable rod 402 . A plurality of through slots 6 are formed on one side of the buffer plate 5 . A plurality of buffer components 4 are distributed along the outer side of the hull 1 .

[0048] It should be noted that the wave compensation mechanism 2 is located on the inner wall of the bottom of the hull 1, and is composed of a wave direction sensing unit, an automatic adjustment filling unit, a balancing unit, and a rapid discharge unit. It can sense the dynamics of ocean waves in real time, and automatically adjust the flow direction and amount of filling in the filling and pumping box 3 to adapt to wave changes. The balancing unit is responsible for sensing the tilt of the hull 1 and adjusting the amount of water in the filling and pumping box to keep the hull 1 level. When the impact of the waves weakens, the rapid discharge unit can quickly discharge the water in the filling and pumping box so that the hull 1 can adapt to the new sea conditions.

[0049] In addition, the buffer assembly 4 is distributed along the outer side of the hull 1, and is composed of a fixed column 401 and a movable rod 402. The movable rod is embedded with a spring 404 to provide additional buffering. A through groove 6 is provided on the buffer plate 5 on one side of the movable rod, and the through groove allows water to pass through when the waves hit, further reducing the direct impact on the hull 1.

[0050] like Figure 1 As shown: A method for wave compensation of an offshore mining vessel, comprising the following steps;

[0051] S1: The wave direction sensing unit is activated to detect waves and collect data;

[0052] It should be noted that the pressure sensor in the wave direction sensing unit is deployed in the hull 1 or the marine environment so as to directly contact the seawater and sense the waves. When the waves pass, the pressure sensor will capture the pressure changes caused by the waves, and the pressure changes caused are converted into electrical signals. The collected electrical signals are then sent to the microcontroller, and the signals are amplified, filtered and digitized. The direction of the waves is calculated by analyzing the processed data.

[0053] S2: The automatic adjustment filling unit receives the wave data and automatically adjusts the filling material in the filling box;

[0054] It should be noted that the automatic adjustment filling unit first receives data from the wave direction sensing unit, and the control algorithm inside the automatic adjustment filling unit analyzes the received wave data to determine the current sea conditions and the tilt degree of the hull 1. According to the results of the data analysis, the automatic adjustment filling unit sends instructions to the filling box 3 at the bottom of the hull 1 to adjust the flow direction of the filler by controlling the opening and closing of the valve. At the same time, in order to adapt to the continuous changes in waves, the automatic adjustment filling unit will continuously monitor the wave data and adjust the distribution of the filler in real time.

[0055] S3: The balance unit senses the tilt of the hull and adjusts the amount of water in the pumping box to keep the hull level;

[0056] It should be noted that a tilt sensor (gyroscope) is installed inside the balancing unit, which can monitor the tilt angle of the hull 1 relative to the horizontal plane in real time. The tilt data collected by the tilt sensor will be sent to the control module of the balancing unit. The control module determines the required adjustment action and sends instructions to the filling and pumping box 3. The balancing unit will continuously monitor the tilt state of the hull 1 and dynamically adjust the amount of water in the filling and pumping box according to the real-time data to ensure that the hull 1 always remains in a near-horizontal state.

[0057] S4: When the waves weaken, the rapid discharge unit discharges the water in the filling and pumping box to adjust the balance of the hull;

[0058] It should be noted that: when the pressure sensor detects that the impact of waves has weakened, the pressure sensor will send an instruction to the quick discharge unit. After receiving the instruction, the quick discharge unit will start the corresponding pump and open the valve to begin to quickly discharge the water in the filling box. During the discharge process, the balance unit will continue to monitor the posture changes of the hull 1 to ensure that the discharge speed and amount meet the requirements of restoring balance. Once the hull 1 reaches a new balance state, the discharge valve will be closed and the pump will be stopped.

[0059] S5: When the operation is completed or balancing is not required, turn off the power supply of the heave compensation mechanism to ensure that all filling and pumping boxes are safely discharged.

[0060] It should be noted that before closing the wave compensation mechanism 2, ensuring that all the filling boxes 3 have been discharged to a safe level is the key to ensuring the safe shutdown of the wave compensation mechanism 2 and avoiding instability of the hull 1 due to improper distribution of fillers when closing the wave compensation mechanism 2.

[0061] The wave direction sensing unit is responsible for real-time monitoring of ocean wave dynamics, including wave direction and intensity. The sensed data is then transmitted to the automatic filling adjustment unit, providing key information for subsequent filling adjustments.

[0062] In S2 , the automatic adjustment filling unit automatically adjusts the flow direction and amount of the filling in the filling box 3 , and the automatic adjustment filling unit intelligently distributes the filling to adapt to the changing wave conditions, thereby maintaining the stability of the hull 1 .

[0063] In S3 , the balancing unit automatically adjusts the amount of water filled in the filling and pumping box 3 on the left or right side of the hull 1 by sensing the tilt of the hull 1 to offset the tilt of the hull 1 .

[0064] In S4 , when the influence of waves weakens and the hull 1 needs to be adjusted to adapt to the new sea conditions, the discharge unit is quickly started, and the discharge unit is responsible for quickly discharging the water in the filling and pumping box 3 to restore the balance of the hull 1 .

[0065] By sensing wave dynamics in real time and automatically adjusting the flow direction and amount of filler, the hull 1 can maintain better stability on the fluctuating sea surface and reduce the shaking and tilting caused by waves. The stable hull 1 environment helps to improve the efficiency of offshore mining operations, ensure the normal operation of mining equipment, and reduce operation interruptions caused by severe sea conditions. The coordinated work of the balancing unit and the rapid discharge unit ensures that the hull 1 can be quickly adjusted to the optimal state under different sea conditions, reducing the safety risks caused by wave impact. The design of the buffer component reduces the direct impact of waves on the hull 1, extends the service life of the hull 1, reduces maintenance costs, reduces the shaking and tilting of the hull 1, provides a more comfortable working environment for the crew, and helps to improve the crew's work performance and quality of life. The through-groove design of the buffer plate allows water to pass through, reducing the impact on the marine environment and reflecting the consideration for environmental protection.

[0066] When the present invention is used, when encountering waves, the pressure sensor starts to work, and monitors the height, period, direction and intensity of ocean waves in real time. The sensed wave data is transmitted to the control system of the automatic adjustment filling unit. The automatic adjustment filling unit automatically adjusts the filling flow direction and amount in the filling box according to the received wave data to adapt to the change of waves. The balancing unit senses the inclination of the hull 1 and automatically adjusts the amount of water in the filling box to offset the inclination of the hull 1 and keep the hull 1 level. For example, the fixed column and the movable rod play a role when the hull 1 is impacted by waves, and absorbs and disperses energy through the built-in spring and buffer plate to reduce the direct impact on the hull 1. When the impact of the waves weakens and the hull 1 needs to be adjusted to adapt to the new sea conditions, the rapid discharge unit is quickly started to discharge the water or other substances in the filling box to restore the balance of the hull 1. During the whole process, the control system continuously monitors the posture and wave data of the hull 1 to ensure that the hull 1 is always kept in the best stable state. When it is not necessary to balance the hull 1 or the operation is completed, the system will be shut down according to a predetermined procedure to ensure that all the filling boxes have been discharged to a safe level, and then the system power is turned off.

[0067] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
