[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0034] Embodiment 1:

[0035] like Figures 1 to 6 As shown, an embodiment of the present application provides a connection device for a floating module, including a limit plate 2, a flexible connector 3, a rigid connector 4 and a switching mechanism 5. The limit plate 2 is used to be movably connected to the floating module 1, the flexible connector 3 is located between the floating module 1 and the limit plate 2, and the flexible connector 3 is movably connected to the floating module 1 and the limit plate 2. The rigid connector 4 includes a first rigid connection component 41 and a second rigid connection component 42, the first rigid connection component 41 is connected to the floating module 1, the second rigid connection component 42 is connected to the limit plate 2, and the first rigid connection component 41 is movably connected to the second rigid connection component 42. The switching mechanism 5 is arranged on the limit plate 2, the switching mechanism 5 is connected to the second rigid connection component 42, and the switching mechanism 5 controls the connection between the first rigid connection component 41 and the second rigid connection component 42.

[0036] When the connection device of the floating module of the embodiment of the present application is used, the first rigid connection component 41 is first connected to the second rigid connection component 42. At this time, the floating module 1 and the limit plate 2 are connected through the rigid connector 4 and the flexible connector 3, and the rigid connector 4 plays a role to meet the stability requirements of the floating module 1. In severe sea conditions, the connection between the first rigid connection component 41 and the second rigid connection component 42 is released through the switching mechanism 5, and the floating module 1 and the limit plate 2 are switched from rigid connection to flexible connection, which is convenient to meet the requirements of the bearing capacity of the connector in severe sea conditions, avoid the rigid connector 4 from being damaged, and further extend the service life of the rigid connector 4.

[0037] In one embodiment, in order to realize the flexible connection between the floating body module 1 and the limiting plate 2, the flexible connector 3 includes two flexible limiting members 31, a piston rod 32 and an elastic member 33. One of the flexible limiting members 31 is connected to the floating body module 1, and the other flexible limiting member 31 is connected to the limiting plate 2. The two ends of the piston rod 32 are movably connected to the two flexible limiting members 31, and the elastic member 33 is sleeved on the piston rod 32, and the two ends of the elastic member 33 are respectively against the two flexible limiting members 31. Preferably, the flexible limiting member 31 is made of rubber material, and the elastic member 33 is a spring.

[0038] The piston rod 32 includes a connected piston body 321 and two stoppers 322, and the two stoppers 322 are respectively located at two ends of the piston body 321. The width of the two stoppers 322 is greater than the width of the piston body 321, so that the piston rod 32 is wide at both ends and thin in the middle.

[0039] The flexible stopper 31 is used to stop the piston rod 32. In order to stop the piston rod 32, a stopper cavity 34 and a stopper through hole are provided on the flexible stopper 31. The stopper through hole is connected to the stopper cavity 34. The two stopper parts 322 are respectively located in the two stopper cavities 34. The piston body 321 passes through the stopper through hole and is connected to the two stopper parts 322. The stopper parts 322 can move in the stopper cavity 34.

[0040] Specifically, the length of the limiting cavity 34 is greater than the length of the limiting portion 322 , and the width of the limiting cavity 34 is greater than the width of the limiting portion 322 , so that the limiting portion 322 can move in the limiting cavity 34 away from or close to the limiting plate 2 .

[0041] Since the piston rod 32 is wide at both ends and thin in the middle, and the limiting portion 322 is located in the limiting cavity 34, the piston rod 32 is limited by the flexible limiting member 31 to ensure that the piston rod 32 will not be separated from the flexible limiting member 31. The flexible limiting member 31 can be connected and fixed to the floating module 1 and the limiting plate 2 by screws and nuts. The floating module 1 and the limiting plate 2 can be connected by two flexible connectors 3, and the two flexible connectors 3 are arranged opposite to each other.

[0042] Since the flexible limiter 31 is made of rubber material, the piston body 321 passes through the limit hole and is connected to the two limit parts 322. The flexible limiter 31 is elastic, so the piston rod 32 can rotate around the limit hole, thereby changing the limit angle between the piston rod 32 and the limit plate 2 or the floating module 1.

[0043] In one embodiment, in order to achieve a rigid connection between the floating module 1 and the limiting plate 2, the first rigid connection assembly 41 includes a first rigid connection piece 411, and the first rigid connection piece 411 is provided with a first rigid connection hole 412. The second rigid connection assembly 42 is movably connected to the first rigid connection piece 411.

[0044] In order to realize the movable connection between the second rigid connection component 42 and the first rigid connection component 411, the second rigid connection component 42 includes a second rigid connection component 421 and a rigid fastener 422. A slideway 423 is provided on the second rigid connection component 421, and the rigid fastener 422 is located in the slideway 423, and the rigid fastener 422 slides in the slideway 423. After the first rigid connection hole 412 is aligned with the slideway 423, one end of the rigid fastener 422 can enter the first rigid connection hole 412. Preferably, the rigid fastener 422 can be an axle pin. When the first rigid connection component 41 and the second rigid connection component 42 are not connected, the rigid fastener 422 is located in the slideway 423, and both ends of the rigid fastener 422 are located inside the slideway 423. When the first rigid connection component 41 and the second rigid connection component 42 are connected, half of the rigid fastener 422 is inserted into the first rigid connection hole 412 to realize the rigid connection between the floating module 1 and the limiting plate 2. The first rigid connector 411 can be connected and fixed to the floating body module 1 by bolts and screws, and the second rigid connector 421 can be integrally cast with the limiting plate 2 .

[0045] In one embodiment, the rigid connector 4 may be located between the two flexible connectors 3 , and the elastic member 33 is compressed when the first rigid connector 411 is connected to the second rigid connector 421 .

[0046] In one embodiment, there may be two first rigid connectors 411, and the two first rigid connectors 411 are arranged at intervals on the floating module 1, and the first rigid connection holes 412 of the two first rigid connectors 411 are arranged opposite to each other. Similarly, there are two second rigid connectors 421, and the two second rigid connectors 421 are located between the two first rigid connectors 411. When the first rigid connector 411 is connected to the second rigid connector 421, the slideway 423 of one of the second rigid connectors 421 is aligned with the first rigid connection hole 412 of one of the first rigid connectors 411, and the second rigid connector 421 is connected to the first rigid connector 411 through the rigid fastener 422; the slideway 423 of another second rigid connector 421 is aligned with the first rigid connection hole 412 of another first rigid connector 411, and the second rigid connector 421 is connected to the first rigid connector 411 through the rigid fastener 422.

[0047] In other embodiments, the second rigid connecting member 421 may also be one, and two slideways 423 and two rigid fasteners 422 are disposed on the second rigid connecting member 421 .

[0048] To facilitate the insertion of the rigid fastener 422 into the first rigid connection hole 412 , the ends of the rigid fastener 422 and the opening of the first rigid connection hole 412 may be rounded, thereby making it easier for the rigid fastener 422 to be inserted into the first rigid connection hole 412 .

[0049] In one embodiment, in order to achieve the connection and release between the first rigid connector 411 and the second rigid connector 421, the switching mechanism 5 includes a first switching component 51, the first switching component 51 is connected to the rigid fastener 422, and the first switching mechanism 5 drives the rigid fastener 422 to slide in the slide 423.

[0050] Specifically, the first switching assembly 51 includes a driving member 511, a winch 512, and a pull rope 513. The driving member 511 is connected to the winch 512, the driving member 511 drives the winch 512 to rotate, the pull rope 513 is wound around the winch 512, the pull rope 513 is connected to the rigid fastener 422, and the pull rope 513 drives the rigid fastener 422 to slide in the slideway 423.

[0051] The driving member 511 may be a hydraulic motor, which is provided with pressure oil by an oil pump 514. An accumulator 515 is connected between the oil pump 514 and the hydraulic motor. The accumulator 515 stores the excess pressure oil output by the oil pump 514 and releases it when needed to supplement the insufficient flow of the oil pump 514 or to deal with an emergency. Sensors may be provided on the hydraulic motor and the pump oil to monitor the pressure.

[0052] The output shaft of the hydraulic motor is connected to the rotating shaft of the drum on the winch 512 , thereby driving the drum to rotate. One end of the pull rope 513 is wound around the drum, and the other end of the pull rope 513 is connected to the rigid fastener 422 .

[0053] The first switching assembly 51 may be disposed between the two second rigid connectors 421, and the winch 512 may be provided with two drums, on which pull ropes 513 are respectively wound, and the two pull ropes 513 are respectively connected to the two rigid fasteners 422. When the hydraulic motor drives the winch 512 to rotate, the pull rope 513 is wound and released at the same time. The pull rope 513 may be a steel wire rope, which has a certain hardness. When the steel wire rope is released, the steel wire rope can push the rigid fastener 422 to move, so that one end of the rigid fastener 422 is inserted into the first rigid connection hole 412. When the steel wire rope is wound, the steel wire rope pulls the rigid fastener 422 out of the first rigid connection hole 412, so that the rigid fastener 422 completely enters the slideway 423. In this embodiment, the ends of the rigid fastener 422 and the slideway 423 are chamfered to reduce friction, so that the pull rope 513 can push the rigid fastener 422 into the first rigid connection hole 412 when released.

[0054] In one embodiment, in order to achieve a rigid connection between the limit plate 2 and the float module 1, the switching mechanism 5 also includes a second switching component 52, which is connected to the float module 1 and drives the float module 1 to move toward or away from the limit plate 2.

[0055] The second switching component 52 is arranged in the middle of the limiting plate 2, and the structure of the second switching component 52 is similar to that of the first switching component 51. The second switching component 52 also includes a driving member 511, a winch 512 and a pull rope 513. The output shaft of the driving member 511 is rotatably connected to the drum on the winch 512, one end of the pull rope 513 is wound around the drum, and the other end of the pull rope 513 is connected to the floating body module 1. The driving member 511 is a hydraulic motor, and the pull rope 513 is a steel wire rope. When the hydraulic motor starts to drive the winch 512 to rotate, the pull rope 513 is wound around the drum, thereby driving the floating body module 1 to move toward the limiting plate 2. The pull rope 513 of the second switching component 52 is located on the center line of the limiting plate 2, and the pull rope 513 of the second switching component 52 and the pull rope 513 of the first switching component 51 will not affect each other due to reasons such as crossing.

[0056] In one embodiment, the winch 512 of the second switching assembly 52 may also be provided with two drums, and the two drums are respectively wound with a pull rope 513, and the two pull ropes 513 are respectively connected to the floating body modules 1 located on opposite sides of the limiting plate 2. In other embodiments, the pull rope 513 of one second switching assembly 52 is connected to one floating body module 1, and the movement of one floating body module 1 is achieved through the first second switching assembly 52.

[0057] The second rigid connector 421 is provided with a pressure sensor 6, which is located at the contact surface between the rigid fastener 422 and the first rigid connector 411. There can be multiple pressure sensors 6, and multiple pressure sensors 6 are arranged around the rigid fastener 422. A monitoring instrument 7 is installed on the limit plate 2, and there can be multiple monitoring instruments 7, which are flow rate monitoring instruments 7, wave height monitoring instruments 7 and wind speed monitoring instruments 7, respectively, for monitoring flow rate, wave height and wind speed data.

[0058] The floating module 1 and the limiting plate 2 of this embodiment are connected through the rigid connector 4 and the flexible connector 3, and the rigid connector 4 and the flexible connector 3 can be switched. In the initial state, the first rigid connector 411 is connected to the second rigid connector 421, and the elastic member 33 of the flexible connector 3 is in a compressed state. The floating module 1 and the limiting plate 2 are rigidly connected, which is convenient for meeting the stability requirements of the floating module 1 under normal working conditions.

[0059] When the monitored flow velocity, wave height, wind speed and pressure reach the warning value, the rigid connection between the floating module 1 and the limit plate 2 is released. That is, the first switching component 51 is started, and the hydraulic motor drives the winch 512 to rotate so that the pull rope 513 is wound on the drum, so that one end of the rigid fastener 422 is completely retracted from the first rigid connection hole 412 to the slideway 423 of the second rigid connection member 421, and the connection between the first rigid connection member 411 and the second rigid connection member 421 is released.

[0060] After releasing the rigid connection between the floating module 1 and the limiting plate 2, switch to a flexible connection. After the connection between the first rigid connector 411 and the second rigid connector 421 is released, the second switching component 52 is activated, and the second switching component 52 releases the pull rope 513 connected to the floating module 1. Since the elastic member 33 was compressed before, the floating module 1 is driven to move away from the limiting plate 2 under the elastic force of the elastic member 33, and switches to a flexible connection. After the rigid connection between the floating module 1 and the limiting plate 2 is switched to a flexible connection, it is easy to meet the bearing capacity requirements of the rigid connector 4 under severe sea conditions, and extend the service life of the rigid connector 4.

[0061] When the flow rate, wave height, wind speed and pressure parameters are reduced to below the warning value, the rigid connection between the floating module 1 and the limit plate 2 is restored. That is, the second switching component 52 is started, and the hydraulic motor of the second switching component 52 drives the winch 512 to rotate so that the pull rope 513 is wound on the drum, and the pull rope 513 pulls the floating module 1 to move in the direction close to the limit plate 2, and then with the assistance of external forces such as barges, the floating module 1 is pulled close to the limit plate 2 until the first rigid connector 411 is aligned with the second rigid connector 421, and the first rigid connector 411 and the second rigid connector 421 connected thereto are fitted so that the first rigid connection hole 412 is aligned with the slide 423. Finally, the first switching component 51 is started again, and the pull rope 513 of the first switching component 51 is released, and the pull rope 513 pushes the rigid fastener 422 in the slide 423 to move, so that half of the rigid fastener 422 is inserted into the first rigid connection hole 412.

[0062] Since the limiting portion 322 can move in the limiting cavity 34 in a direction away from or close to the limiting plate 2 , when the floating body module 1 is pulled close to the limiting plate 2 , the piston rod 32 will not affect the movement of the floating body module 1 .

[0063] The above-mentioned warning value is that the maximum pressure value measured by the pressure sensor 6 is greater than the pressure allowed by the rigid fastener 422, or the wind speed is 12m / s, while the flow velocity and wave height are used to assist manual judgment.

[0064] The size of a single floating module 1 is relatively large. In order to achieve the connection between the floating module 1 and the limit plate 2, three groups of flexible connectors 3 and three groups of rigid connectors 4 are generally provided at the bottom, middle and top along the height direction of the floating module 1, so as to share the excessive connection force. The connectors at the bottom, middle and top share the connection force and torque as evenly as possible, balance the load, better buffer the connection force, and increase the service life and safety of the flexible connectors 3 and the rigid connectors 4.

[0065] In one embodiment, the same limiting plate 2 can be connected to four floating modules 1 respectively. In order to realize the connection between the limiting plate 2 and the four floating modules 1, flexible connectors 3 and rigid connectors 4 are respectively arranged on the four sides of the limiting plate 2. The second switching component 52 is located in the middle of the limiting plate 2, and the number of the second switching components 52 can be two or four. Preferably, the connection device of the floating module is symmetrical about the middle longitudinal section and centrally symmetrical.

[0066] Since the connection device of the floating module is provided with a rigid connector 4, a flexible connector 3 and a switching mechanism 5, the present embodiment can control the damage that may be caused by friction and collision of the rigid connector 4 under harsh working conditions by appropriately adjusting the height of the flexible limiter 31 so that it meets the use requirements. The flexible connector 3 under harsh working conditions allows the distance between the limiter plate 2 and the floating module 1 to be adjusted. When the floating module 1 is impacted by external force, it is connected and supported by the elastic member 33 to autonomously adjust the vertical distance between the limiter plate 2 and the floating module 1. The angle between each module can increase or decrease with the force size and distribution of the equipment, so that the above-water part can work normally.

[0067] The present application adopts a method of switching between rigid connection and flexible connection, which can better compensate for the deficiency of inability to timely feedback of force response, optimize the relative motion constraint degree between the floating modules 1 and their own force response, and solve the problem of collision and pulling between the floating modules 1 in the prior art that is more serious when the environmental conditions are harsh.

[0068] Embodiment 2:

[0069] The present embodiment is described in detail below with reference to the first embodiment:

[0070] The embodiment of the present application provides a method for using the connection device of the floating module as described in the first embodiment, comprising the following steps:

[0071] S1: In the initial state, the floating module 1 and the limiting plate 2 are connected via the rigid connector 4, and at this time, the first rigid connection component 41 is connected to the second rigid connection component 42.

[0072] In the initial state, the first rigid connector 411 is connected to the second rigid connector 421, the elastic member 33 of the flexible connector is in a compressed state, and the floating module 1 and the limiting plate 2 are rigidly connected, so as to meet the stability requirements of the floating module 1 under normal working conditions.

[0073] S2: When the monitored data information reaches the warning value, the connection between the first rigid connection component 41 and the second rigid connection component 42 is released through the switching mechanism 5. At this time, the floating module 1 and the limiting plate 2 are connected through the flexible connector 3.

[0074] When the monitored flow velocity, wave height, wind speed and pressure reach the warning value, the rigid connection between the floating module 1 and the limit plate 2 is released. That is, the first switching component 51 is started, and the hydraulic motor drives the winch 512 to rotate so that the pull rope 513 is wound on the drum, so that one end of the rigid fastener 422 is completely retracted from the first rigid connection hole 412 to the slideway 423 of the second rigid connection member 421, and the connection between the first rigid connection member 411 and the second rigid connection member 421 is released.

[0075] After releasing the rigid connection between the floating module 1 and the limiting plate 2, switch to a flexible connection. After the connection between the first rigid connector 411 and the second rigid connector 421 is released, the second switching component 52 is activated, and the second switching component 52 releases the pull rope 513 connected to the floating module 1. Since the elastic member 33 was compressed before, the floating module 1 is driven to move away from the limiting plate 2 under the elastic force of the elastic member 33, and switches to a flexible connection. After the rigid connection between the floating module 1 and the limiting plate 2 is switched to a flexible connection, it is easy to meet the bearing capacity requirements of the rigid connector 4 under severe sea conditions, and extend the service life of the rigid connector 4.

[0076] S3: When the monitored data information drops below the warning value, the connection between the first rigid connection component 41 and the second rigid connection component 42 is achieved through the switching mechanism 5.

[0077] When the flow rate, wave height, wind speed and pressure parameters are reduced to below the warning value, the rigid connection between the floating module 1 and the limit plate 2 is restored. That is, the second switching component 52 is started, and the hydraulic motor of the second switching component 52 drives the winch 512 to rotate so that the pull rope 513 is wound on the drum, and the pull rope 513 pulls the floating module 1 to move in the direction close to the limit plate 2, and then with the assistance of external forces such as barges, the floating module 1 is pulled close to the limit plate 2 until the first rigid connector 411 is aligned with the second rigid connector 421, and the first rigid connector 411 and the second rigid connector 421 connected thereto are fitted so that the first rigid connection hole 412 is aligned with the slide 423. Finally, the first switching component 51 is started again, and the pull rope 513 of the first switching component 51 is released, and the pull rope 513 pushes the rigid fastener 422 in the slide 423 to move, so that half of the rigid fastener 422 is inserted into the first rigid connection hole 412.

[0078] The above-mentioned warning value is that the maximum pressure value measured by the pressure sensor 6 is greater than the pressure allowed by the rigid fastener 422, or the wind speed is 12m / s, while the flow velocity and wave height are used to assist manual judgment.
