As shown in fig. 1, in one embodiment of the present invention, a heave compensation stabilizer is provided, which includes:
a support member 100 for supporting the working device 400 provided on a surface thereof;
and a motion compensation member 200 connected to the support member 100 for acting when the support member 100 is tilted with respect to a horizontal plane to compensate for the tilting displacement of the support member 100, thereby ensuring that the support member 100 can stably support the working device 400 such that different portions of the surface of the support member 100 are maintained at the same horizontal plane.
The shaking of the ship mainly has the following six forms: roll, pitch, yaw, heave, yaw, pitch. The influence of pitching and rapid heaving on the navigation of the ship is the largest, when the ship sways, the support member 100 can incline relative to the horizontal plane, and at the moment, the displacement of the inclination of the support member 100 can be compensated by driving the motion compensation member 200 to move, so that different parts of the surface of the support member 100 can be always kept on the same horizontal plane.
The utility model discloses can compensate support member 100's slope position when boats and ships rock to make support member 100 keep relatively stable in the space, even boats and ships rock in the stormy waves and also can make support member 100 surface can keep the level basically, thereby guarantee to install the position of the attachment (work equipment 400) on support member 100 stable all the time. The utility model discloses reduced the influence of boats and ships swaying and heaving motion in the stormy waves to marine operation and equipment, effectively guaranteed boats and ships/platform operation safety, improved work efficiency.
Because the supporting part 100 is less influenced by the swinging of the ship, the position of the lifter is more stable after the lifter is arranged on the supporting part 100, the goods are more easily driven to take off and land by the lifter, the goods cannot collide due to the swinging in the lifting process, and the probability of safety accidents is reduced; the working device 400 is not affected by shaking after being mounted to the support member 100, and thus normal operation of the seabed is not affected.
Referring to fig. 1, in some embodiments, the motion compensation member 200 is disposed around the circumference of the support member 100, and the motion compensation member 200 is coupled to different positions of the circumferential edge of the support member 100. The motion compensation part 200 is connected with different positions of the circumferential edge of the support part 100, when one of the positions is raised or lowered, the motion compensation part 200 surrounding the support part 100 can act to keep the position at the same level with other positions, and compared with the adjustment of the middle part of the support part 100, the adjustment efficiency is higher and the effect is better. In other embodiments, the motion compensation component 200 may be disposed directly below the support component 100, and is not limited herein.
With continued reference to fig. 1, in some embodiments, the motion compensation component 200 includes a plurality of telescopic compensation mechanisms 210, the plurality of telescopic compensation mechanisms 210 are respectively connected to a plurality of connection points distributed at the circumferential edge of the support component 100, and the telescopic compensation mechanisms 210 change length by telescoping to adjust the horizontal position of the connection points. When the support member 100 is inclined due to the up and down movement of the connection points, the plurality of telescopic compensation mechanisms 210 change the length by telescopic movement, thereby adjustably changing the horizontal position of the connection points and compensating the displacement of the connection points at the inclined positions, and finally making the surface of the support member 100 be at the same horizontal plane. The embodiment can correspondingly adjust the horizontal position of each connecting point, and can adjust different positions in a targeted manner, and the plurality of telescopic compensation mechanisms 210 do not interfere with each other, and the adjustment accuracy can be ensured by independent driving.
Preferably, the telescopic compensating mechanism 210 includes a base 211, a vertical telescopic rod 212 and a balance rod 213. Two ends of the vertical telescopic rod 212 are respectively connected with the base 211 and the connection points of the circumferential edges of the supporting part 100; the balance bar 213 is connected to the connection point and the base 211 at two ends, and the balance bar 213 is not parallel to the vertical telescopic bar 212. The vertical telescopic rod 212 changes the horizontal height of the connecting point through the telescopic length change adjustment, so that the surface of the supporting component 100 can be in the same horizontal plane, and it should be noted that the balance rod 213 of the present invention is directly connected with the connecting point and the base 211, and the balance rod 213 has a balance function, on one hand, the vertical telescopic rod 212 can be supported, and the vertical telescopic rod 212 is prevented from inclining by the lateral force; on the other hand, the balance bar 213, the vertical telescopic bar 212 and the base 211 are matched together to form a triangular support structure, and the support structure has stronger spatial stability and better balance, so that the overall structure of the telescopic compensation mechanism 210 is more stable. Preferably, the vertical expansion rod 212 is a telescopic cylinder. Further, the balance bar 213 is connected with the base 211 through the balance bar bracket 214, and the balance bar bracket 214 enables the balance bar 213 to be connected with the base 211 more stably, so that the stability of the whole telescopic compensation mechanism 210 is enhanced. It is understood that in other embodiments, the telescopic compensation mechanism 210 includes only the vertical telescopic rod 212, and is not limited thereto.
Of course, in other embodiments, the motion compensation unit 200 includes a swing cylinder disposed on the lower surface of the support unit 100, and the support unit 100 is adjusted to maintain the surface parallel to the horizontal plane by driving the swing cylinder to swing.
Referring to fig. 1, in some embodiments, the supporting member 100 includes a supporting platform 110 and a supporting frame 120 disposed on a lower surface of the supporting platform 110. The support frame 120 serves to support and reinforce the overall strength of the support platform 110, and can ensure safety in use even under severe ocean conditions.
In some embodiments, a posture sensing component and a control unit are also included. The attitude sensing means is provided to the support means 100 for detecting the attitude of the support means 100; the control unit is in communication connection with the attitude sensing component and motion compensation component 200 and is used for driving the motion compensation component 200 according to the pose parameters detected by the attitude sensing component.
Specifically, the attitude sensing component is an attitude sensor, the attitude sensor is a high-performance three-dimensional motion attitude measurement system based on the MEMS technology, and the zero-drift three-dimensional attitude azimuth data expressed by quaternions and euler angles is output in real time mainly by using a quaternion-based three-dimensional algorithm and a special data fusion technology, so that the swing attitude of the support component 100 is acquired in real time. When the control unit judges that the support member 100 is inclined with respect to the horizontal plane based on the parameter detected by the posture sensing member, the control unit controls and drives the motion compensation member 200 to compensate for the inclination displacement of the support member 100, so that different portions on the support member 100 can be maintained at the same horizontal plane. Specifically, when the motion compensation component 200 is a hydraulic oil cylinder, the control unit may control the hydraulic system to inject hydraulic oil to each hydraulic oil cylinder, and compensate for the displacement of the support component 100 when the support component 100 is tilted by changing the length of each hydraulic oil cylinder, so as to finally keep different parts on the support component 100 on the same horizontal plane; when the motion compensation member 200 is an electric telescopic rod, the control unit can directly control the electric telescopic rod to extend or shorten to compensate the displacement of the inclination of the supporting member, and finally, different parts on the supporting member 100 can be kept on the same horizontal plane.
In practice, it has been found that the work equipment 400 placed on the surface of the support member 100 is prone to toppling under high-wave conditions, especially during transportation of the equipment, and the bumpy environment can easily cause the work equipment 400 to tilt or even fall directly from the support platform 110. To this end, in some embodiments, an edge locking assembly 300 is also included, the edge locking assembly 300 including a lock press 310 and an actuator 320. The locking and pressing piece 310 comprises a connecting end 311 and a locking and pressing end 312, wherein the connecting end 311 is hinged on the surface of the supporting component 100; the driving member 320 is connected to the locking end 312 for driving the locking end 312 to press the edge 401 of the working device 400 against the surface of the supporting member 100.
The edge 401 of the working device 400 is placed under the locking and pressing member 310, and the driving member 320 drives the locking and pressing end 312 to press down to press the edge 401 of the working device 400 against the surface of the supporting member 100. As shown in fig. 2-4, taking the working device 400 as an example of a wind turbine, after the edge 401 (flange ring) at the bottom of the tower of the wind turbine, which is vertically placed, is locked and fixed, the installation position of the whole wind turbine on the ship can be ensured to be stable, and the probability of the wind turbine inclining relative to the supporting platform 110 or separating from the supporting platform 110 is reduced, so that the position of the attachment (the working device 400) installed on the supporting platform 110 is ensured to be stable, and the safety of the ship/platform operation is further improved.
Preferably, the driving member 320 includes an oil cylinder 321 and an oil cylinder support 322 for installing the oil cylinder 321, the oil cylinder support 322 is disposed on the surface of the supporting member 100, and two ends of the oil cylinder 321 are respectively hinged to the oil cylinder support 322 and the pressure locking end 312.
Preferably, the edge locking unit 300 has a plurality of edges 401 extending along the surface of the support unit 100 corresponding to the working device 400. Specifically, the number of the edge locking members 300 may be adjusted according to the weight and height of the working equipment 400, such as a tower of a wind turbine generator, and when the weight and height of the working equipment are large, a large number of edge locking members need to be arranged to enhance the locking force on the working equipment; when the weight and the height of the working equipment are smaller, the edge locking components with less arrangement quantity can meet the use requirement.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
