In the field of ocean engineering, moon pool systems are commonly used to create a more stable mini-environment than a floating body structure in a harsh ocean environment to facilitate the operation of other underwater equipment 100 such as scientific equipment.

Fig. 1 illustrates a schematic structural diagram of a moon pool system in one embodiment provided by the present utility model. As shown in fig. 1, the moon pool system generally comprises a moon pool surrounding wall 1, a moon pool bottom cover 2, a deployment device 3 and a moon pool top cover 4, wherein the moon pool surrounding wall 1 penetrates through the deck of each layer of the ship and communicates with seawater, and forms a relatively stable seawater environment within the moon pool surrounding wall 1; the moon pool bottom cover 2 is rotatably connected to the moon pool surrounding wall 1 and can seal the lower end opening of the moon pool surrounding wall 1, the moon pool top cover 4 is rotatably connected to the moon pool surrounding wall 1 and can seal the upper end port of the moon pool surrounding wall 1, and the distributing device 3 is used for distributing the underwater equipment 100.

The moon pool bottom cover 2 is rotatable with respect to the moon pool surrounding wall 1, and has a bottom end closing position that shields the lower end opening of the moon pool surrounding wall 1 and a bottom end opening position that avoids the lower end opening of the moon pool surrounding wall 1. The moon pool cover 4 is rotatable with respect to the moon pool surrounding wall 1, and has a top end closing position for shielding an upper end opening of the moon pool surrounding wall 1 and a top end opening position for avoiding the upper end opening of the moon pool surrounding wall 1. The rotation axis of the moon pool bottom cover 2 is perpendicular to the rotation axis of the moon pool top cover 4. By the arrangement, the connection position between the moon pool bottom cover 2 and the moon pool surrounding wall 1 and the connection position between the moon pool top cover 4 and the moon pool surrounding wall 1 are staggered in the vertical direction, and the whole of the moon pool surrounding wall 1 can be ensured to be uniformly stressed up and down.

The pulley mechanism 31 comprises a sliding rail 311, a pulley 312, a guide wheel 313, a lifting cable 314 and a pulley 312 driver, wherein the sliding rail 311 extends along the vertical direction and is fixed on the moon pool surrounding wall 1, the pulley 312 can lift along the sliding rail 311, the guide wheel 313 is fixed on the moon pool surrounding wall 1 or a ship deck through a bracket, one end of the lifting cable 314 is connected with the pulley 312, the other end of the lifting cable 314 is in transmission connection with the pulley 312 driver, and the pulley 312 driver is used for driving the lifting cable 314 to pull the pulley 312 to lift along the sliding rail 311. The docking mechanism 32 is mounted on the trolley 312, and can be lifted along the sliding rail 311 along with the trolley 312, so that the docking mechanism 32 can lift the underwater device 100.

Since the sliding rail 311 of the pulley mechanism 31 is mounted on the moon pool enclosure wall 1, the lifting stroke of the pulley mechanism 31 is limited, and when the pulley mechanism 31 conveys the docking mechanism 32 together with the underwater equipment 100 to the ship bottom position, the underwater equipment 100 is closer to the ship bottom, and under the influence of sea water fluctuation, there is a risk of collision damage between the underwater equipment 100 and the ship bottom.

When the pulley 312 of the pulley mechanism 31 moves to the bottom of the sliding rail 311, the lifting mechanism 33 is used to drive the guide mechanism 32 to descend for the second time, so that the distance between the guide mechanism 32 and the underwater equipment 100 and the bottom end (i.e. the bottom of the ship) of the moon pool enclosure wall 1 is increased, and the guide mechanism 32 and the underwater equipment 100 are prevented from colliding with the bottom of the ship under the surging of sea waves.

Fig. 2 shows an enlarged view at a in fig. 1. As shown in fig. 2, the lifting mechanism 33 includes a rack and pinion assembly and a lifting driver 333, the rack and pinion assembly includes a gear 331 and a rack 332, the gear 331 is rotatably mounted on the pulley 312, the rack 332 is meshed with the gear 331, the guide mechanism 32 is fixedly connected with the rack 332, and the lifting driver 333 drives the gear 331 to rotate, so that the rack 332 is lifted relative to the pulley 312, and the guide mechanism 32 is lifted along with the lifting of the rack 332. The guide mechanism 32 comprises a mounting plate 321 and a guide connector 322, wherein the mounting plate 321 is fixedly connected with the rack 332, and the guide connector 322 is mounted on the mounting plate 321 and used for receiving the underwater equipment 100. Alternatively, in other embodiments, in the lifting mechanism 33, a screw-nut assembly may be used instead of the rack-and-pinion assembly, and the screw-nut assembly may also be used to implement the secondary lifting of the docking mechanism 32.

Fig. 3 shows a schematic top view of the lifting mechanism 33 of the moon pool system in fig. 1. As shown in fig. 3, the trolley 312 is provided with rollers, and the rollers are in rolling fit with the sliding rail 311. The two sliding rails 311 are arranged in parallel at intervals, two groups of rollers are arranged on the pulley 312, and each group of rollers is in rolling fit with one sliding rail 311. With this arrangement, the trolley 312 can be stably and smoothly lifted along the slide rail 311.

As further shown in fig. 3, in order to ensure the stability of lifting of the guide mechanism 32, the lifting mechanism 33 is provided with three groups, the three groups of lifting mechanisms 33 are arranged at intervals along the circumferential side of the mounting plate 321 of the guide mechanism 32, and the mounting plate 321 of the guide mechanism 32 is fixedly connected with the racks 332 of the three groups of lifting mechanisms 33.

Of course, in other embodiments, the number of lifting mechanisms 33 is not limited to three, but may be any number of two, four, etc., and will not be illustrated here.

Fig. 4 is a schematic view showing a structure of the elevating mechanism 33 secondary driving docking mechanism 32 of the moon pool system of fig. 1. Fig. 5 shows a schematic view of a structure in which the docking mechanism 32 of the moon pool system of fig. 1 releases the underwater equipment 100. As shown in fig. 4 to 5, when the underwater apparatus 100 needs to be deployed, the trolley 312 of the trolley mechanism 31 firstly descends to the bottom of the ship with the docking mechanism 32, then the docking mechanism 32 is driven by the lifting mechanism 33 to descend away from the bottom of the ship for the second time, and finally the underwater apparatus 100 is released by the docking mechanism 32 for underwater operation. After the underwater equipment 100 finishes the underwater operation, the underwater equipment 100 is recovered by the guide connection mechanism 32, then the lifting mechanism 33 drives the guide connection mechanism 32 to ascend, and finally the pulley 312 of the pulley mechanism 31 drives the guide connection mechanism 32 to ascend to the initial position for the second time.

Fig. 6 is a schematic structural view of a moon pool system according to another embodiment of the present utility model. Fig. 7 shows a schematic top view of the airbag 341 in fig. 6. As shown in fig. 7 in combination with fig. 6, in order to solve the problem of collision damage of the underwater apparatus 100 with the bottom of the ship, the deployment device 3 includes a protection mechanism 34, the protection mechanism 34 includes an airbag 341 and an air cylinder 342, the airbag 341 is disposed along the peripheral side of the docking mechanism 32, and the air cylinder 342 is communicated with the airbag 341 for inflating the inside of the airbag 341. Before the underwater equipment 100 is deployed, the airbag 341 is in an uninflated storage state, and when the trolley 312 conveys the guide mechanism 32 to the bottom of the ship, the gas cylinder 342 inflates the airbag 341, and the airbag 341 is positioned between the underwater equipment 100 and the bottom end of the moon pool enclosure wall 1 after being inflated, so that the underwater equipment 100 can be protected. In this embodiment, the elevating mechanism 33 is not provided on the sled 312, and only the airbag 341 is provided. Of course, in other embodiments, the lifting mechanism 33 and the airbag 341 may be provided at the same time, which will not be described here.

As further shown in fig. 7, the air bag 341 is annular, and the diameter of the inflated air bag 341 is not smaller than the opening at the lower end of the moon pool surrounding wall 1, so that the air bag 341 is stably clamped between the moon pool surrounding wall 1 and the underwater equipment 100, and the underwater equipment 100 is prevented from colliding with the moon pool surrounding wall 1 or the bottom of a ship under the surge of seawater waves. Illustratively, the cross-sectional shape of the moon pool surrounding wall 1 is square, and the diameter of the inflated airbag 341 is not smaller than the length of the lower end opening of the moon pool surrounding wall 1. Specifically, a gas cylinder 342 and a gas release control unit are additionally provided on the sled 312 to provide the gas required for the airbag 341.

During deployment, the trolley 312 firstly conveys the guide connection mechanism 32 to the bottom of the ship, and then inflates the air bag 341 through the air bottle 342 and the air release control unit, so that the air bag 341 is inflated above the underwater equipment 100, collision between the underwater equipment 100 and the bottom of the ship is avoided, and the underwater equipment 100 is better protected; when the underwater operation of the underwater apparatus 100 is completed, the gas in the airbag 341 may be exhausted, and then the docking mechanism 32 and the underwater apparatus 100 thereon may be transported to a starting position using the sled 312. It should be noted that, the communication manner between the gas cylinder 342 and the airbag 341 may be a conventional technical means in the airbag field, and the gas release control unit may also be a conventional control element in the airbag field, which is not described herein.

The moon pool system with the airbag 341 provided in the above-described embodiment can solve the problem that the conventional moon pool system can only transport the underwater device 100 to a position closer to the bottom of the ship to collide with the bottom of the ship.

The moon pool systems provided in the above embodiments all include a set of deployment devices 3, where the set of deployment devices 3 includes a pair of pulley mechanisms 31 and a guide mechanism 32, and only one underwater device 100 is deployed, so that the requirement of the operation of simultaneously deploying two underwater devices 100 cannot be met; in addition, the carrying capacity of the one set of deployment devices 3 is limited, so that it is difficult to meet the deployment requirements of the large-sized underwater equipment 100, and when the deployment devices 3 fail, time is required for maintenance, so that the deployment efficiency of the underwater equipment 100 of the whole ship is affected.

Fig. 8 is a schematic view showing a structure in which a moon pool system simultaneously transports two underwater devices 100 in still another embodiment provided by the present utility model. Fig. 9 shows a schematic structural view of the moon pool system of fig. 8 for transporting a large-sized underwater device 100. As shown in fig. 8-9, in order to solve the problems that one set of deployment device 3 has low operation efficiency and is not suitable for deployment of large-scale underwater equipment 100, the moon pool system comprises two sets of deployment devices 3, namely, two pairs of pulley mechanisms 31 and guide and connect mechanisms 32 are provided, the pulley mechanisms 31 and the guide and connect mechanisms 32 are matched one by one for use, and compared with the traditional moon pool system with only one set of deployment device 3, the two sets of deployment devices 3 can improve the deployment efficiency of the underwater equipment 100 of a ship, and further improve the operation efficiency of a scientific investigation ship.

The two sets of laying devices 3 work independently, and can simultaneously and independently realize the laying operation of different underwater equipment 100. When the large-scale underwater equipment 100 is required to be deployed, the control of the two pulley mechanisms 31 is transferred to the common control system, so that the cooperative operation of the two pulley mechanisms 31 is realized, and the large-scale underwater equipment 100 is deployed. When the lifting driver 333 of one pulley mechanism 31 fails, the moon pool bottom cover 2 can be closed, and after the water in the moon pool surrounding wall 1 is pumped out, the lifting cable 314 of the other non-failure pulley mechanism 31 is connected to the guide wheel 313 of the failure pulley mechanism 31, so that the pulley 312 of the failure pulley mechanism 31 is driven to lift by the lifting driver 333 of the normal pulley mechanism 31, and the two pulley mechanisms 31 are mutually standby, thereby improving the operation efficiency of the ship.

For the large moon pool system, when the size of the moon pool surrounding wall 1 is large, the moon pool top cover 4 of a large size is required to close the upper end opening of the moon pool surrounding wall 1, however, the large size of the moon pool top cover 4 is large in size and heavy in weight, a large power source is required to drive, and the large size of the moon pool top cover 4 is inconvenient to operate. In particular, for a moon pool system with a double-set laying device 3, the moon pool top cover 4 needs to be opened no matter the double-set laying device 3 works simultaneously or works independently, so that power waste is caused.

In order to solve the above problems, two moon pool covers 4 may be provided at the upper end of the moon pool surrounding wall 1, and the two moon pool covers 4 may be opened and closed independently, and the corresponding moon pool covers 4 may be opened or closed according to the laying operation requirement, thereby improving the convenience of operation.

After a moon pool bottom cover 2 of a large moon pool system is opened, the free liquid level of seawater in the moon pool is larger due to the larger size of a moon pool surrounding wall 1, and in a wave environment, the seawater in the moon pool surrounding wall 1 can generate the phenomena of wave in the pool such as heave, horizontal sway and the like, and the wave in the pool has larger impact force on the moon pool surrounding wall 1, so that the ship is easy to shake; and the waves in the pool have impact influence on the laying device 3 and the underwater equipment 100, so that the failure rate of the laying device 3 is increased.

Fig. 10 is a schematic front view showing a moon pool system according to still another embodiment of the present utility model. Fig. 11 shows a schematic side view of the moon pool system in fig. 10. As shown in fig. 10 to 11, in order to reduce the influence of the sea wave in the moon pool enclosure wall 1 on the moon pool system, the moon pool system further comprises a wave-absorbing device 5, and the influence of the sea wave motion on the moon pool system is reduced by utilizing the power of the sea wave-absorbing device 5 to attenuate the sea wave.

The wave absorbing device 5 comprises a wave absorbing wall 51, the wave absorbing wall 51 is arranged on the side wall of the moon pool surrounding wall 1, the wave absorbing wall 51 is of a porous double-wall structure, and the porous double-wall structure can weaken the motion of sea waves and reduce the influence of the sea waves on a moon pool system. However, although the wave-absorbing wall 51 has a good wave-absorbing effect, the space occupied by the wave-absorbing wall 51 is large. When the moon pool top cover 4 and the moon pool bottom cover 2 are opened, since the storage space needs to be reserved on the side wall of the moon pool surrounding wall 1, the space at the position corresponding to the side wall of the moon pool surrounding wall 1 after the moon pool top cover 4 and the moon pool bottom cover 2 are opened is narrow, and the wave-absorbing wall 51 is not suitable for being mounted, so that the coverage area of the wave-absorbing wall 51 in the moon pool surrounding wall 1 is limited, and the wave-absorbing effect is general.

For the moon pool system with larger moon pool surrounding wall 1, the moon pool top cover 4 and the moon pool bottom cover 2 have larger sizes, and the occupied space is larger, so that the installation space of the wave-absorbing wall 51 is limited, the size of the wave-absorbing wall 51 is smaller, and the wave-absorbing effect is poorer.

In order to solve the above problem, the wave-absorbing device 5 includes wave-absorbing modules, and at least two sets of wave-absorbing modules are disposed on the moon pool enclosure wall 1. For example, when the cross-sectional shape of the moon pool surrounding wall 1 is square, two sets of wave absorbing modules are symmetrically arranged on the moon pool surrounding wall 1, and the two sets of wave absorbing modules are arranged on the corresponding side wall of the moon pool surrounding wall 1 when the moon pool top cover 4 is opened. Of course, in other embodiments, four sets of wave absorbing modules may be disposed on the four sidewalls of the moon pool enclosure wall 1.

The wave-absorbing module comprises wave-absorbing components 52, and a plurality of groups of wave-absorbing components 52 are arranged on the side wall of the moon pool surrounding wall 1 in a square array. Illustratively, 12 sets of wave absorbing members 52 are arranged in a 3 x 4 rectangular array on the side walls of the moon pool enclosure wall 1. Of course, in other embodiments, there may be any number of the wave absorbing members 52, which may be arranged in a rectangular array, of 15 sets, 16 sets, 18 sets, etc., and are not illustrated herein.

Continuing with fig. 11, the wave absorbing assembly 52 includes a wave absorbing plate 521 and a stay bar 522, one end of the wave absorbing plate 521 is connected to the side wall of the moon pool surrounding wall 1, the other end of the wave absorbing plate 521 is connected to one end of the stay bar 522, the other end of the stay bar 522 is fixedly connected to the side wall of the moon pool surrounding wall 1, the wave absorbing plate 521 is disposed at an acute angle to the horizontal surface, and the wave absorbing plate 521 is used for reducing wave motion of seawater.

Fig. 12 shows a schematic structural view of a first form of the wave absorbing assembly 52 of the moon pool system in fig. 11. As shown in fig. 12, the wave absorbing plate 521 is disposed at an acute angle with respect to the horizontal plane, and the connection position between the wave absorbing plate 521 and the side wall of the moon pool surrounding wall 1 is higher than the connection position between the stay 522 and the side wall of the moon pool surrounding wall 1, i.e. the wave absorbing plate 521 is disposed obliquely downward. For the case that the heave component of the sea wave motion of the moon pool surrounding wall 1 is large, the heave component of the wave motion can be better weakened by selecting the wave-absorbing plate 521 which is arranged in a declining wave-pressing mode. Alternatively, in fig. 12, the wave absorbing plate 521 is rotatably connected to the side wall of the moon pool surrounding wall 1 through a hinge, the wave absorbing plate 521 is also rotatably connected to the stay 522 through a hinge, and the stay 522 is detachably and fixedly connected to the side wall of the moon pool surrounding wall 1 through a bolt. When the moon pool bottom cover 2 is not opened, an operator firstly enters the moon pool surrounding wall 1, the stay bar 522 is fixed on the moon pool surrounding wall 1 through bolts, the wave-absorbing plate 521 is arranged at an acute angle with the horizontal plane, and the wave motion of the sea water is weakened by the wave-absorbing plate 521. Of course, in other embodiments, when the space between the side wall of the moon pool surrounding wall 1 and the opened moon pool top cover 4 is large enough, the wave absorbing plate 521 and the side wall of the moon pool surrounding wall 1, the wave absorbing plate 521 and the stay bar 522, and the stay bar 522 and the side wall of the moon pool surrounding wall 1 are fixedly connected by welding, bolts, etc., so that the wave absorbing plate 521 is always in a state of forming an acute angle with the horizontal plane, no manual pre-installation is needed, and the working efficiency is improved.

Illustratively, when the opening size of the moon pool surrounding wall 1 is small (e.g., the side length of the moon pool surrounding wall 1 is less than 4 meters) and the side length of the moon pool surrounding wall 1 is much smaller than the width of the ship (e.g., the side length of the moon pool surrounding wall 1 is less than 1/4 of the width of the ship), the heave component of the sea wave motion in the moon pool surrounding wall 1 is large, and the above-mentioned wave-absorbing member 52 of the declining and pressing type is preferably used.

Fig. 13 shows a schematic structural view of a second form of the wave absorbing assembly 52 of the moon pool system in fig. 11. As shown in fig. 13, the wave absorbing plate 521 is disposed at an acute angle with respect to the horizontal plane, and the connection position of the wave absorbing plate 521 and the side wall of the moon pool surrounding wall 1 is lower than the connection position of the stay 522 and the side wall of the moon pool surrounding wall 1, i.e., the wave absorbing plate 521 is disposed obliquely upward. For the case that the horizontal oscillation component of the sea wave motion of the moon pool surrounding wall 1 is large, the wave-absorbing plate 521 arranged in an upward reflection wave mode is selected to better weaken the horizontal oscillation component of the wave motion. Alternatively, in fig. 13, the wave absorbing plate 521 is rotatably connected to the side wall of the moon pool surrounding wall 1 through a hinge, the wave absorbing plate 521 is also rotatably connected to the stay 522 through a hinge, and the stay 522 is detachably and fixedly connected to the side wall of the moon pool surrounding wall 1 through a bolt. When the moon pool bottom cover 2 is not opened, an operator firstly enters the moon pool surrounding wall 1, the stay bar 522 is fixed on the moon pool surrounding wall 1 through bolts, the wave-absorbing plate 521 is arranged at an acute angle with the horizontal plane, and the wave motion of the sea water is weakened by the wave-absorbing plate 521. Of course, in other embodiments, when the space between the side wall of the moon pool surrounding wall 1 and the opened moon pool top cover 4 is large enough, the wave absorbing plate 521 and the side wall of the moon pool surrounding wall 1, the wave absorbing plate 521 and the stay bar 522, and the stay bar 522 and the side wall of the moon pool surrounding wall 1 are fixedly connected by welding, bolts, etc., so that the wave absorbing plate 521 is always in a state of forming an acute angle with the horizontal plane, no manual pre-installation is needed, and the working efficiency is improved.

Illustratively, when the opening size of the moon pool surrounding wall 1 is large (e.g., the side length of the moon pool surrounding wall 1 is greater than 4 meters) and the side length of the moon pool surrounding wall 1 is slightly smaller than the width of the ship (e.g., the side length of the moon pool surrounding wall 1 is greater than 1/4 of the width of the ship), the horizontal sway component of the sea wave motion in the moon pool surrounding wall 1 is large, and the above-mentioned upward reflection type wave-absorbing member 52 is preferably used.

Whether the wave-absorbing assembly 52 is arranged in a downward-inclined wave-pressing manner or the wave-absorbing assembly 52 is arranged in an upward-reflecting manner, the included angle between the wave-absorbing plate 521 and the horizontal plane is 30-55 degrees, preferably 45 degrees. The width of the wave absorbing plate 521 is not less than 1/10 of the side wall length of the moon pool surrounding wall 1. The width of the wave-absorbing plate 521 and the angle between the wave-absorbing plate 521 and the horizontal plane can be simulated and optimized by CFD software, and will not be described here again.

As shown in fig. 12 to 13, in order to ensure the connection strength between the wave-absorbing assembly 52 and the side wall of the moon pool surrounding wall 1, whether the wave-absorbing assembly 52 is arranged in a downward-inclined wave-pressing manner or the wave-absorbing assembly 52 is arranged in an upward-reflecting manner, the wave-absorbing assembly 52 further comprises a wall plate supporting member 523, the wall plate supporting member 523 is mounted on the side wall of the moon pool surrounding wall 1, and then the wave-absorbing plate 521 and the stay 522 are mounted on the wall plate supporting member 523.
