DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0029] See also Figure 1-9An attitude adjustment device for an ocean exploration vessel according to an embodiment of the present invention is used to keep a working vessel 100 in a stable attitude, and includes an attitude acquisition component 200, a center of gravity adjustment component 300, and a control component 400; the attitude acquisition component 200 includes a collection vessel 210 and a recorder 220, the distance between the collection vessel 210 and the working vessel 100 is a processing interval, the collection vessel 210 is arranged at an upstream position of the working vessel 100 on the sea level, and the recorder 220 is installed on the collection vessel 210 to record the first attitude information of the collection vessel 210 and the seawater flow rate information; the center of gravity adjustment component 300 includes a counterweight structure 310, which is slidably connected to the workboat 100 and is used to move on the workboat 100 to adjust the center of gravity of the workboat 100; the control component 400 is installed on the workboat 100, and the control component 400 receives the first posture information and seawater flow rate information sent by the recorder 220, and the control component 400 obtains the action time according to the processing interval and the seawater flow rate information, and the control component 400 controls the counterweight structure 310 to move on the workboat 100 according to the action time and the seawater flow rate information.

[0030] Here, the working boat 100 and the collecting boat 210 are both arranged on the sea level, and the distance between the collecting boat 210 and the working boat 100 is maintained as the processing interval. The collecting boat 210 is provided with a posture collecting structure for collecting the first posture information of the hull and a seawater velocity collecting structure for collecting the seawater velocity information. The posture collecting structure can adopt the hull posture monitoring system disclosed in Chinese patent CN115393806A or the hull posture detection device disclosed in Chinese patent CN109572958B, and the seawater velocity collecting structure can adopt the seawater velocity monitoring device disclosed in Chinese patent CN216408465U or the acoustic Doppler current profiler disclosed in Chinese patent CN213902451U. The posture collecting structure and the seawater velocity collecting structure in this application can both adopt the equipment in the prior art, that is, the first posture information and the seawater velocity information of the collecting boat 210 in this application can both be obtained by using the prior art. The control component 400 is connected to the recorder 220 signal to receive the first posture information and seawater flow rate information of the collection ship 210. The output end of the control component 400 is connected to the counterweight structure 310 to drive the counterweight structure 310 to slide according to the first posture information and seawater flow rate information.

[0031] Specifically, during the process of the working boat 100 drilling down to collect samples, the attitude collection component 200 is provided, including a collection boat 210 and a recorder 220. The collection boat 210 and the working boat 100 are provided on the sea level, and a processing interval is formed between them. The recorder 220 is installed on the collection boat 210 to record the first attitude information of the collection boat 210 and the seawater flow rate information. The collection boat 210 is provided on the sea level at an upstream position of the working boat 100, and can know in advance the seawater wave information to be transmitted to the working boat 100, and reflect the seawater wave information through the first attitude information of the collection boat 210. At the same time, the time for the seawater wave to be transmitted from the collection boat 210 to the working boat 100 can be known through the processing interval and the seawater flow rate information. In order to avoid the working boat 100 being affected by the seawater wave In order to produce turbulence due to the influence, the center of gravity adjustment component 300 includes a counterweight structure 310, which is slidably connected to the workboat 100 to adjust the center of gravity of the workboat 100. In order to control the posture adjustment component to adjust the workboat 100 to an adaptive amplitude at an accurate time, a control component 400 is installed on the workboat 100. The control component 400 is connected to the recorder 220 signal to receive the first posture information of the collection ship 210 and the seawater flow rate information. The output end of the control component 400 is connected to the counterweight structure 310 to drive the counterweight structure 310 to slide according to the first posture information and the seawater flow rate information, thereby ensuring that the workboat 100 can stably maintain its posture even if it is affected by sea waves, thereby ensuring the normal operation of sampling tools such as drill rods and drill bits.

[0032] It should be noted that the work boat 100 is an exploration vessel, which has the function of drilling and sampling, and can maintain the current position by means of structures such as a propulsion device arranged at the bottom.

[0033] Specifically, the posture acquisition component 200 in the present application is a structure set at a certain distance away from the workboat 100, which can replace the workboat 100 in advance to sense the sea waves that are about to be transmitted to the workboat 100, and make corresponding posture changes. According to the posture changes made, the workboat 100 can be controlled to make corresponding center of gravity adjustments to resist sea waves. Figure 3 As shown, the attitude collection component 200 includes a collection ship 210 and a recorder 220. The collection ship 210 and the working ship 100 are arranged on the sea level and a processing distance is formed between them. The recorder 220 is installed on the collection ship 210 to record the first attitude information of the collection ship 210 and the seawater flow rate information. Figure 2As shown, the center of gravity adjustment assembly 300 in the present application is a structure for adjusting the center of gravity of the workboat 100. After adjusting the center of gravity of the workboat 100, the tendency of the workboat 100 to roll over and the sea waves in the corresponding direction offset each other, thereby maintaining the posture of the workboat 100. Specifically, the center of gravity adjustment assembly 300 includes a counterweight structure 310, which is slidably connected to the workboat 100 to adjust the center of gravity of the workboat 100.

[0034] The control component 400 may include a posture controller, a delay controller and an actuator; the posture controller receives the first posture information sent by the recorder 220; the delay controller receives the seawater flow rate information sent by the recorder 220, and the delay controller calculates the action time based on the seawater flow rate information and the processing interval; the actuator receives the second posture information sent by the posture controller and the action time sent by the delay controller, and controls the counterweight structure 310 to move on the workboat 100 according to the first posture information when the time is the action time.

[0035] Specifically, the control component 400 in this embodiment is used to receive the attitude signal and seawater flow rate signal of the collection ship 210 recorded by the recorder 220, and control the workboat 100 to delay the corresponding center of gravity adjustment. Specifically, the control component 400 is installed on the workboat 100, and the control component 400 is connected to the recorder 220 signal to receive the first attitude information and seawater flow rate information of the collection ship 210. The output end of the control component 400 is connected to the counterweight structure 310 to drive the counterweight structure 310 to slide according to the first attitude information and the seawater flow rate information. The attitude controller is connected to the counterweight structure 310 via an actuator. Among them, the actuator can be a driving member 34, the delay controller is a switch that controls the action of the driving member 34, and the attitude controller controls the time of the forward and reverse rotation of the driving member 34, that is, controls the counterweight structure 310 to slide to different positions on the slide rail structure 320. The first posture information is that the collection ship 210 is tilted toward one side, and the working ship 210 is parallel to the collection ship 210, then the control component 400 drives the counterweight structure 310 to slide in the opposite direction of the side where the collection ship 210 is tilted, with the center line of the working ship 210 parallel to the width as the due north-due south direction, and the due east-due west direction perpendicular to the due north-due south direction, then a plane coordinate system is formed. If the sea waves blow the collection ship 210 from the due north direction, the collection ship 210 tilts toward the due south direction, then the posture information of the collection ship 210 is tilted toward the due south direction, at this time the work ship 210 will also be blown by the sea waves coming from the due north direction, at this time the work ship 210 tilts toward the due south direction, then the control component 400 drives the counterweight structure 310 to slide toward the due north direction.

[0036] like Figure 3As shown, the attitude collection component 200 may further include a signal transmitter 230 . The signal transmitter 230 is installed on the collection ship 210 . The recorder 220 is connected to the control component 400 via the signal transmitter 230 .

[0037] Specifically, in order to transmit the first posture information of the collection vessel 210 and the seawater flow rate information to the control component 400, in one embodiment, the posture collection component 200 also includes a signal transmitter 230, and the signal transmitter 230 is installed on the collection vessel 210, and the recorder 220 is connected to the control component 400 via the signal transmitter 230.

[0038] like Figure 1 As shown, there may be multiple posture acquisition components 200 , and the multiple posture acquisition components 200 are evenly arranged on the work boat 100 in a circumferential direction.

[0039] Specifically, in order to collect sea wave information that is about to be transmitted to the workboat 100 from different directions, in one embodiment, the number of attitude collection components 200 is multiple, and the multiple attitude collection components 200 are evenly arranged along the circumference of the workboat 100. An attitude collection component 200 is set in the east, west, south and north directions of the workboat 100; if sea waves blow from the east direction of the workboat 100, then the attitude collection components 200 located in the north direction, south direction and east direction will all feel the sea waves in the east direction, and the attitude collection component 200 located in the west direction will not feel the sea waves in the east direction. The collection boat 210 in the attitude collection components 200 in the north direction, south direction and east direction will tilt toward the west. If it is the same sea wave, then the seawater flow rate information is the same, and the north direction, south direction and east direction positions The first posture acquisition information and the seawater flow rate information in the posture acquisition component 200 are the same. The posture acquisition component 200 located in the east direction first feels the seawater waves in the east direction, and the control component 100 first receives the first posture acquisition information and the seawater flow rate information sent by the posture acquisition component 200 in the east direction, and the control component 100 directly drives the counterweight structure 310 to move toward the east direction according to the first posture information and the seawater flow rate information; if the seawater waves blow from the north direction of the working boat 100, the acquisition boat 2 in the posture acquisition components 200 in the north direction, the west direction, and the east direction 10 is tilted toward the south, then the first posture collection information and seawater flow rate information in the posture collection components at the north, west and east positions are the same, the posture collection component 200 at the north position first feels the sea waves in the north direction, then the control component 100 first receives the first posture collection information and seawater flow rate information sent by the posture collection component 200 at the east position, then the control component 100 drives the counterweight structure 310 to move toward the north according to the first posture information and the seawater flow rate information; if the seawater waves blow from the west direction of the workboat 100, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the west position, the north position, the east ... The collection ship 210 in the attitude collection component 200 at the east position and the south position tilts toward the east, then the first attitude collection information and the seawater flow rate information in the attitude collection component 200 at the west position, the north position, and the south position are the same, and the attitude collection component 200 at the west position first feels the seawater waves in the west direction, then the control component 100 first receives the first attitude collection information and the seawater flow rate information sent by the attitude collection component 200 at the west position, and then the control component 100 drives the counterweight structure 310 to move toward the west according to the first attitude information and the seawater flow rate information;If the sea waves blow from the south of the workboat 100, the collection boat 210 in the attitude collection components 200 at the south, west, and east positions tilts toward the north, then the first attitude collection information and the seawater flow rate information in the attitude collection components at the south, west, and east positions are the same, and the attitude collection component 200 at the south position first senses the sea waves from the south, then the control component 100 first receives the first attitude collection information and the seawater flow rate information sent by the attitude collection component 200 at the south position, and then the control component drives the counterweight structure 310 to move toward the south according to the first attitude information and the seawater flow rate information. ;

[0040] like Figure 3 As shown, as a posture adjustment device for an ocean exploration vessel in this embodiment, it also includes a connecting rope 240 with two ends respectively connected to the working ship 100 and the collecting ship 210 for adjusting the processing spacing size, and a thruster 250 is installed at the bottom of the collecting ship 210 for controlling the collecting ship 210 to maintain the current position when the connecting rope 240 is adjusted.

[0041] Specifically, the connecting rope 240 can be a cable. In order to ensure that the processing distance between the collection ship 210 and the work ship 100 is constant, in one embodiment, the collection ship 210 is connected to the work ship 100 via a cable. A propeller 250 is installed at the bottom of the collection ship 210. The propeller 250 is used to control the collection ship 210 to fix the current position. At the same time, the size of the processing distance is adjusted by the cable. One end of the cable is connected to a winch. When the cable is released, the processing distance between the collection ship 210 and the work ship 100 can be adjusted to be larger. When the cable is wound, the processing distance between the collection ship 210 and the work ship 100 can be adjusted to be smaller, thereby realizing the recovery of the collection ship 210 by the winch.

[0042] like Figure 2 As shown in FIGS. 4-9 , the center of gravity adjustment assembly 300 may also include a slide rail structure 320 disposed on the workboat 100, a slider structure 330 disposed at the bottom of the counterweight structure 310, and a driving member 34 connected to the slider structure 330. The slider structure 330 is slidably connected to the slide rail structure 320. The driving member 34 drives the slider structure 330 to drive the counterweight structure 310 to move on the slide rail structure 320. Each driving member 34 is disposed corresponding to each slider structure 330.

[0043] Specifically, in order to realize the movement of the counterweight structure 310, the counterweight structure 310 is slidably connected to the work boat 100 via a slide rail structure 320 fixed on the work boat 100, such as Fig. 9As shown, in order to achieve the sliding of the counterweight structure 310 relative to the slide rail structure 320, the counterweight structure 310 is slidably connected to the slide rail structure 320 via the slider structure 330, and the driving member 34 is installed on the slider structure 330. The output end of the driving member 34 is connected to the slide rail structure 320 to drive the slider structure 330 to slide, and the driving member 34 is electrically connected to the control component 400.

[0044] like Figure 4-5 As shown, the slide rail structure 320 may include a horizontally arranged X-axis slide rail 311 and a horizontally arranged Y-axis slide rail 313, and the counterweight structure 310 includes a horizontally arranged X-axis counterweight block 312 and a horizontally arranged Y-axis counterweight block 314. The X-axis slide rail 311 and the Y-axis slide rail 313 are perpendicular to each other, and a slider structure 330 is provided at the bottom of each X-axis slide rail 311 and the Y-axis slide rail 313.

[0045] Specifically, for ease of understanding, the working principle of the center of gravity adjustment assembly 300 is described in detail. The length direction of the work boat 100 is assumed to be direction X, and the width direction of the work boat 100 is assumed to be direction Y. The X-direction slide rail 311 is parallel to direction X, and the Y-direction slide rail 313 is parallel to direction Y. The X-direction slide rail 311 and the Y-direction slide rail 313 are both fixedly connected to the work boat 100 and are arranged perpendicular to each other. The X-direction counterweight block 312 is slidably connected to the X-direction slide rail 311, and the Y-direction counterweight block 314 is slidably connected to the Y-direction slide rail 313. Each slider structure corresponds to a driving member 34, and the control assembly 400 is electrically connected to the plurality of driving members 34, respectively. The control assembly 400 controls the plurality of driving members 34, respectively. After controlling the corresponding driving member 34, the driving member 34 drives the corresponding slider structure 330, and the slider structure 330 moves on the corresponding X-direction slide rail 311 and the Y-direction slide rail 313.

[0046] like Figure 6-8 As shown, the slide rail structure 320 can also include multiple inclined slide rails 315, the counterweight structure 310 includes multiple inclined counterweight blocks 316, a wellhead is provided in the middle of the workboat 100, and multiple inclined slide rails 315 are evenly arranged around the wellhead. One end of the multiple inclined slide rails 315 points to the center position of the wellhead, and a slider structure 330 is provided at the bottom of each inclined slide rail 315, and each slider structure 330 is arranged corresponding to each driving member 34.

[0047] Specifically, the inclined rail 315 and the X-direction center line of the wellhead parallel to the direction X are inclined, that is, the angle between the inclined rail 315 and the X-direction center line of the wellhead is an acute angle, and the angle between the inclined rail 315 and the X-direction rail 311 is an acute angle. Multiple inclined rails 315 are evenly arranged along the circumference of the wellhead opened on the workboat 100 and are all set to point to the center position of the wellhead. Multiple inclined counterweights 316 are slidably connected to the multiple inclined rails 315. When the workboat 100 is subjected to seawater waves in the direction X, such as Figure 7 As shown, the four oblique counterweights 316 can move in the direction corresponding to the direction X. When the workboat 100 is subjected to seawater waves in the direction Y, as shown in FIG. Figure 8 As shown, the four oblique counterweights 316 can move in the direction corresponding to the direction Y. The center of gravity adjustment speed is fast, and the entire center of gravity adjustment assembly 300 occupies less space in the work boat 100.
