As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0034] Example 1:

[0035] like Figures 1 to 6 As shown in the figure, this application embodiment provides a connection device for a floating module, including a limiting plate 2, a flexible connector 3, a rigid connector 4, and a switching mechanism 5. The limiting plate 2 is used for movable connection with the floating module 1. The flexible connector 3 is located between the floating module 1 and the limiting plate 2, and is movably connected to both the floating module 1 and the limiting 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, and the second rigid connection component 42 is connected to the limiting plate 2. The first rigid connection component 41 and the second rigid connection component 42 are movably connected. The switching mechanism 5 is disposed on the limiting plate 2 and is connected to the second rigid connection component 42. The switching mechanism 5 controls the connection between the first rigid connection component 41 and the second rigid connection component 42.

[0036] The connecting device of the floating body module in the embodiment of the application is used in the following manner: first, the first rigid connecting assembly 41 is connected with the second rigid connecting assembly 42, at this time, the floating body module 1 is connected with the limiting plate 2 through the rigid connector 4 and the flexible connector 3, the rigid connector 4 plays a role, and the stability requirement of the floating body module 1 is met. In a severe sea state, the connection between the first rigid connecting assembly 41 and the second rigid connecting assembly 42 is released through the switching mechanism 5, and the connection between the floating body module 1 and the limiting plate 2 is switched from rigid connection to flexible connection, so as to meet the requirement of the bearing capacity of the connector in the severe sea state, avoid the rigid connector 4 from being damaged, and further prolong the service life of the rigid connector 4.

[0037] In an embodiment, in order to realize the flexible connection between the floating body module 1 and the limiting plate 2, the flexible connector 3 comprises two flexible limiting pieces 31, a piston rod 32 and an elastic piece 33. One of the two flexible limiting pieces 31 is connected with the floating body module 1, and the other flexible limiting piece 31 is connected with the limiting plate 2. The piston rod 32 is movably connected with the two flexible limiting pieces 31 at two ends thereof, and the elastic piece 33 is sleeved on the piston rod 32 and abuts against the two flexible limiting pieces 31 at two ends thereof. Preferably, the flexible limiting piece 31 is made of rubber material, and the elastic piece 33 is a spring.

[0038] The piston rod 32 comprises a piston body 321 and two limiting portions 322 connected with each other, and the two limiting portions 322 are located at two ends of the piston body 321. The width of the two limiting portions 322 is greater than the width of the piston body 321, so that the piston rod 32 has a shape of wide at two ends and narrow in the middle.

[0039] The flexible limiting piece 31 is used for limiting the piston rod 32. In order to realize the limitation of the piston rod 32, the flexible limiting piece 31 is provided with a limiting cavity 34 and a limiting through hole in communication with the limiting cavity 34. The two limiting portions 322 are located in the two limiting cavities 34 respectively, the piston body 321 is connected with the two limiting portions 322 after passing through the limiting through hole, and the limiting portion 322 can move in the limiting 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 in the direction away from or close to the limiting plate 2.

[0041] Since the piston rod 32 has a shape of wide at two ends and narrow 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 piece 31, so that the piston rod 32 cannot be separated from the flexible limiting piece 31. The flexible limiting piece 31 can be connected and fixed with the floating body module 1 and the limiting plate 2 through screws and nuts. The floating body module 1 and the limiting plate 2 can be connected through the two flexible connectors 3, and the two flexible connectors 3 are oppositely arranged.

[0042] Since the flexible limiting member 31 is made of rubber material, the piston body 321 is connected with the two limiting portions 322 after passing through the limiting through hole, and the flexible limiting member 31 has elasticity, so that the piston rod 32 can rotate around the limiting through hole, thereby changing the limiting angle between the piston rod 32 and the limiting plate 2 or the float module 1.

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

[0044] In order to realize the movable connection between the second rigid connection assembly 42 and the first rigid connecting piece 411, the second rigid connection assembly 42 comprises a second rigid connecting piece 421 and a rigid fastener 422. The second rigid connecting piece 421 is provided with a sliding channel 423, and the rigid fastener 422 is located in the sliding channel 423 and slides in the sliding channel 423. After the first rigid connecting hole 412 and the sliding channel 423 are aligned, one end of the rigid fastener 422 can enter the first rigid connecting hole 412. Preferably, the rigid fastener 422 can be a shaft pin. In the state that the first rigid connection assembly 41 and the second rigid connection assembly 42 are not connected, the rigid fastener 422 is located in the sliding channel 423, and both ends of the rigid fastener 422 are located inside the sliding channel 423. When the first rigid connection assembly 41 and the second rigid connection assembly 42 are connected, half of the rigid fastener 422 is inserted into the first rigid connecting hole 412, thereby realizing the rigid connection between the float module 1 and the limiting plate 2. The first rigid connecting piece 411 can be connected and fixed with the float module 1 by bolts and screws, and the second rigid connecting piece 421 can be integrally casted with the limiting plate 2.

[0045] In an embodiment, the rigid connector 4 can be located between the two flexible connectors 3, and the elastic member 33 is compressed when the first rigid connecting piece 411 and the second rigid connecting piece 421 are connected.

[0046] In an embodiment, the first rigid connecting member 411 can be two, the two first rigid connecting members 411 are arranged at intervals on the floating body module 1, and the first rigid connecting holes 412 of the two first rigid connecting members 411 are arranged oppositely. Similarly, the second rigid connecting member 421 can also be two, the two second rigid connecting members 421 are located between the two first rigid connecting members 411. When the first rigid connecting member 411 and the second rigid connecting member 421 are connected, the slide 423 of one of the second rigid connecting members 421 is aligned with the first rigid connecting hole 412 of one of the first rigid connecting members 411, and the second rigid connecting member 421 is connected to the first rigid connecting member 411 through the rigid fastener 422; the slide 423 of the other second rigid connecting member 421 is aligned with the first rigid connecting hole 412 of the other first rigid connecting member 411, and the second rigid connecting member 421 is connected to the first rigid connecting member 411 through the rigid fastener 422.

[0047] In other embodiments, the second rigid connecting member 421 can also be one, and the second rigid connecting member 421 is provided with two slides 423 and two rigid fasteners 422.

[0048] In order to facilitate the insertion of the rigid fastener 422 into the first rigid connecting hole 412, the end of the rigid fastener 422 and the opening of the first rigid connecting hole 412 can be chamfered, so that the rigid fastener 422 is more easily inserted into the first rigid connecting hole 412.

[0049] In an embodiment, in order to realize the connection and release of the first rigid connecting member 411 and the second rigid connecting member 421, the switching mechanism 5 includes a first switching assembly 51, the first switching assembly 51 is connected with 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 with the winch 512, the driving member 511 drives the winch 512 to rotate, the pull rope 513 is wound on the winch 512, the pull rope 513 is connected with the rigid fastener 422, and the pull rope 513 drives the rigid fastener 422 to slide in the slide 423.

[0051] Among them, the driving member 511 can be a hydraulic motor, the hydraulic motor is provided with pressure oil by an oil pump 514, and an accumulator 515 is connected between the hydraulic motor and the oil pump 514. 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 cope with emergency situations. A sensor can be arranged on the oil pump to monitor the pressure.

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

[0053] The first switching assembly 51 can be arranged between the two second rigid connecting members 421, and two winding drums can be arranged on the winch 512, and the two winding drums are respectively wound with the pull ropes 513, and the two pull ropes 513 are respectively connected with the two rigid fasteners 422. When the hydraulic motor drives the winch 512 to rotate, the winding and releasing of the pull rope 513 are simultaneously realized. The pull rope 513 can 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 connecting hole 412. When the steel wire rope is wound, the steel wire rope pulls the rigid fastener 422 out of the first rigid connecting hole 412, so that the rigid fastener 422 completely enters the slide 423. In this embodiment, the end of the rigid fastener 422 and the end of the slide 423 are both chamfered, so as to reduce the friction, and the pull rope 513 can push the rigid fastener 422 to enter the first rigid connecting hole 412 when the pull rope 513 is released.

[0054] In an embodiment, in order to realize the rigid connection between the limiting plate 2 and the floating body module 1, the switching mechanism 5 further comprises a second switching assembly 52. The second switching assembly 52 is connected with the floating body module 1, and the second switching assembly 52 drives the floating body module 1 to move towards or away from the limiting plate 2.

[0055] The second switching assembly 52 is arranged at the middle part of the limiting plate 2, and the structure of the second switching assembly 52 is similar to that of the first switching assembly 51. The second switching assembly 52 also comprises a driving member 511, a winch 512 and a pull rope 513. The output shaft of the driving member 511 is connected with the winding drum on the winch 512, one end of the pull rope 513 is wound on the winding drum, and the other end of the pull rope 513 is connected with 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 is started to drive the winch 512 to rotate, the pull rope 513 is wound on the winding drum, so as to drive the floating body module 1 to move towards the limiting plate 2. The pull rope 513 of the second switching assembly 52 is located on the center line of the limiting plate 2, and the pull rope 513 of the second switching assembly 52 and the pull rope 513 of the first switching assembly 51 do not affect each other due to crossing or other reasons.

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

[0057] The second rigid connecting piece 421 is provided with a pressure sensor 6, which is located at the contact surface of the rigid fastener 422 and the first rigid connecting piece 411. The pressure sensor 6 can be multiple, which are arranged around the rigid fastener 422. The limiting plate 2 is provided with monitoring instruments 7, which can be multiple, and the multiple monitoring instruments 7 are flow rate monitoring instruments 7, wave height monitoring instruments 7 and wind speed monitoring instruments 7 respectively, which are used to monitor the flow rate, wave height and wind speed data.

[0058] The floating body module 1 and the limiting plate 2 of the embodiment are connected through the rigid connector 4 and the flexible connector 3, and the switching of the rigid connector 4 and the flexible connector 3 can be realized. In the initial state, the first rigid connecting piece 411 is connected with the second rigid connecting piece 421, and the elastic member 33 of the flexible connector 3 is in the compressed state, so that the floating body module 1 and the limiting plate 2 are rigidly connected, which is convenient for meeting the stability requirement of the floating body module 1 under normal working conditions.

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

[0060] After the rigid connection between the floating body module 1 and the limiting plate 2 is released, the flexible connection is switched. After the connection between the first rigid connecting piece 411 and the second rigid connecting piece 421 is released, the second switching assembly 52 is started, and the second switching assembly 52 releases the pull rope 513 connected with the floating body module 1. Since the elastic member 33 is compressed before, the floating body module 1 is driven to move away from the limiting plate 2 under the elastic force of the elastic member 33, and the flexible connection is switched. After the rigid connection between the floating body module 1 and the limiting plate 2 is switched to the flexible connection, it is convenient to meet the bearing capacity requirement of the rigid connector 4 under severe sea conditions, and the service life of the rigid connector 4 is prolonged.

[0061] When the flow rate, wave height, wind speed and pressure and other parameters are reduced to the pre-warning value, the rigid connection between the floating body module 1 and the limiting plate 2 is restored. That is, the second switching assembly 52 is started, the hydraulic motor of the second switching assembly 52 drives the winch 512 to rotate to make the pull rope 513 wind on the drum, the pull rope 513 pulls the floating body module 1 to move towards the limiting plate 2, and then an external force such as a barge is used to pull the floating body module 1 to approach the limiting plate 2 until the first rigid connecting piece 411 is aligned with the second rigid connecting piece 421, and the first rigid connecting piece 411 and the second rigid connecting piece 421 connected thereto are in close contact to make the first rigid connecting hole 412 aligned with the slide 423. Finally, the first switching assembly 51 is started, the pull rope 513 of the first switching assembly 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 connecting hole 412.

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

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

[0064] The size of a single floating body module 1 is large, in order to realize the connection between the floating body module 1 and the limiting plate 2, generally three groups of flexible connectors 3 and three groups of rigid connectors 4 are arranged in the height direction of the floating body module 1 at the lower part, the middle part and the upper part, so as to share the excessive connecting force. The connectors at the lower part, the middle part and the upper part share the connecting force and the moment as much as possible, balance the load, better buffer the connecting force, and increase the service life and safety of the flexible connector 3 and the rigid connector 4.

[0065] In an embodiment, the same limiting plate 2 can be connected with four floating body modules 1 respectively, in order to realize the connection between the limiting plate 2 and the four floating body modules 1, flexible connectors 3 and rigid connectors 4 are arranged on the four sides of the limiting plate 2 respectively, the second switching assembly 52 is located in the middle of the limiting plate 2, and the number of the second switching assembly 52 can be two or four. Preferably, the connection device of the floating body module is symmetrical about the median longitudinal plane and central symmetry.

[0066] The connection device of the floating body module is provided with the rigid connector 4, the flexible connector 3 and the switching mechanism 5, and the damage of the rigid connector 4 caused by friction and collision in the harsh working condition can be controlled by adjusting the height of the flexible limiting piece 31 to meet the use requirement. The distance between the limiting plate 2 and the floating body module 1 can be adjusted by the flexible connector 3 in the harsh working condition. When the floating body module 1 is impacted by external force, the vertical distance between the limiting plate 2 and the floating body module 1 is adjusted by the elastic piece 33, and the angle between the modules can be increased or decreased according to the force and distribution of the equipment, so that the water part can work normally.

[0067] The rigid connection and the flexible connection are switched in the application, the deficiency that the force reaction cannot be fed back in time is well compensated, the relative motion constraint degree between the floating body modules 1 and the force response of the floating body modules 1 are optimized, and the problem that the collision and pulling between the floating body modules 1 are more serious in the harsh environment condition is solved.

[0068] Embodiment two:

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

[0070] The application embodiment provides a use method of the connection device of the floating body module as described in the embodiment one, and the use method comprises the following steps:

[0071] S1: in the initial state, the floating body module 1 is connected with the limiting plate 2 through the rigid connector 4, and the first rigid connection assembly 41 is connected with the second rigid connection assembly 42 at this time.

[0072] In the initial state, the first rigid connecting piece 411 is connected with the second rigid connecting piece 421, the elastic piece 33 of the flexible connecting piece is in the compressed state, the floating body module 1 is rigidly connected with the limiting plate 2, and the stability requirement of the floating body module 1 in the normal working condition can be met.

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

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

[0075] The rigid connection between the floating body module 1 and the limiting plate 2 is switched to a flexible connection. After the connection between the first rigid connecting piece 411 and the second rigid connecting piece 421 is released, the second switching assembly 52 is started, the second switching assembly 52 releases the pull rope 513 connected with the floating body module 1, and the floating body module 1 is driven to move away from the limiting plate 2 under the elastic force of the elastic member 33, and the switching is switched to a flexible connection. After the rigid connection between the floating body module 1 and the limiting plate 2 is switched to a flexible connection, the carrying capacity requirement of the rigid connector 4 in severe sea conditions is met, and the service life of the rigid connector 4 is prolonged.

[0076] S3: When the monitored data information decreases to below the early warning value, the connection between the first rigid connecting assembly 41 and the second rigid connecting assembly 42 is realized through the switching mechanism 5.

[0077] When the flow rate, wave height, wind speed, and pressure parameters decrease to below the early warning value, the rigid connection between the floating body module 1 and the limiting plate 2 is restored. That is, the second switching assembly 52 is started, the hydraulic motor of the second switching assembly 52 drives the winch 512 to rotate to make the pull rope 513 wind on the drum, the pull rope 513 pulls the floating body module 1 to move towards the limiting plate 2, and the floating body module 1 is pulled towards the limiting plate 2 by external force such as a barge until the first rigid connecting piece 411 and the second rigid connecting piece 421 are aligned, and the second rigid connecting piece 421 connected with the first rigid connecting piece 411 is in close contact to make the first rigid connecting hole 412 aligned with the slide 423. Finally, the first switching assembly 51 is started, the pull rope 513 of the first switching assembly 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 connecting hole 412.

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