The present invention will be described in further detail with reference to specific embodiments.

As shown in fig. 1-30, the present invention provides a floating amusement device on the sea that can be divided into two types, one being a small device placed relatively near the shore, as shown in fig. 1, and primarily providing relatively simple swimming, dining, diving, etc., activities, with the guest set to go and go the day. Another is a large equipment for open sea, as shown in fig. 10, which can provide tourists with all-directional recreational activities, and the journey of the tourists is set to 3 to 15 days.

As shown in fig. 1 and 10, the equipment mainly comprises a plurality of modules of semi-submersible offshore floating platforms 100 and a plurality of modules of semi-submersible offshore floating pools 200, which are all of modular space truss structures; the semi-submersible offshore floating platform 100 of several modules forms a platform assembly as the equipment body, and the platform assembly is anchored in a selected sea area by a multi-point anchoring system through mooring lines 6 and gravity anchor blocks 7.

As shown in fig. 2 to 5, the semi-submersible offshore floating platform 100 includes a deck platform, a semi-submersible buoyant body 10 and a buoyant body, which are arranged in the vertical direction from top to bottom; the deck platform comprises an upper platform main deck 1001 and a stepped sunken deck 1002, wherein the sunken deck 1002 is provided with steps 1004 for communicating the upper platform main deck 1001 with an annular deck 2001 of the semi-submersible offshore floating pool 200. The upper main deck of the platform assembly provides a building foundation for equipping an upper building, and the platform assembly also provides splicing conditions for the floating swimming pool. Preferably, the superstructure on the platform upper main deck 1001 includes a dock, a restaurant, a bar, a theater, a dance hall, a hotel, an outdoor square, a large tree, a lawn, and the like. Preferably, a bottom deck 2005 is provided on the bottom buoyant truss structure 2004.

As shown in fig. 6a-c, the semi-submersible offshore floating pool 200 is an annular groove structure, and includes an annular deck 2001, a submerged annular rod truss structure 2002, an annular main buoyancy module truss structure 2003, and a bottom buoyancy truss structure 2004, which are arranged in vertical sequence from top to bottom, on the periphery of the pool. Preferably, the inner side of the groove structure is provided with a side-surrounding flexible anti-shark net 2006 for separating water bodies inside and outside the swimming pool.

Preferably, artificial beach 1003 is provided on the sunken deck 1002 and/or the annular deck 2001. As shown in fig. 7a-b, the artificial beach 1003 is composed of an upper frame 10031, a middle sand-separating water-permeable net 10032 and a lower steel grid bearing layer 10033, quartz sand is placed in a groove formed by the frame 10031 and the bottom net, the inner edge of the frame 10031 is designed to be an outward slope to reduce the surface width of the sand groove frame, and the upper part is a round angle to prevent people from being injured by contact. On the steel grid bearing layer 10033, a mounting base of a hidden sun umbrella or other facilities can be designed.

As shown in fig. 8-9, the positive and negative height difference between the annular deck 2001 and sea level is adjusted by adjusting the height of the submerged annular bar truss structure 2002; the height of the upper plane of the annular deck can be designed to be higher than the sea water plane or lower than the sea water plane, the annular deck is designed to be high, and the artificial beach sand is positioned above the water surface and can be used for resting; the annular deck is low-level design, and artificial sandy beach is located the surface of water below, can form no boundary swimming pool effect, and at this moment artificial sandy beach can be used to trickle water and play. In this example, the high level scenario is 25 centimeters above water and the low level scenario is 25 centimeters below water. Since the artificial sand beach is located in the wave action zone, the contents of the artificial sand beach should be changed from quartz sand to pebbles to prevent wash-out.

Adjusting net depth within the swimming pool by selecting different height mounting ports of the bottom buoyancy truss structure 2004 inside the annular main buoyancy module truss structure 2003; in this example, the depth is zero meters, 2 meters, 4.5 meters, 7 meters, and 9.5 meters, and the five steps are adjustable.

The overall depth of the semi-submersible offshore floating pool 200 is adjusted from 12.5 m to 60 m by synchronously increasing or decreasing the height of the semi-submersible buoyancy body 10 to the buoyancy body and the height of the submersible ring-shaped rod truss structure 2002, which can be used for deep submergence.

The semi-submersible type floating swimming pool is integrally arranged on the platform assembly, the lifting of the semi-submersible type floating swimming pool is driven by the lifting of the platform assembly (the lifting is specially in a small size range, namely less than 50cm), and the buoyancy of the semi-submersible type floating swimming pool can be adjusted.

Under the overall specific condition of the equipment, the buoyancy of each platform and each swimming pool main buoyancy module can be adjusted (increased) in an emergency manner, so that the emergency floating can be realized.

As shown in fig. 10, an example of the offshore floating amusement equipment in open sea mode is mainly composed of 7 semi-submersible offshore floating

platforms

100 and 3 semi-submersible offshore floating pools 200, which have a larger main deck area for placing superstructures and have more steps and artificial sand beach. Compared with the semi-submersible offshore floating platforms of the peripheral modules, the semi-submersible offshore floating platform of the middle module is different in that a sinking deck is not arranged, a horizontal rod piece connected with the semi-submersible offshore floating swimming pool does not need to be arranged, an anchoring system can be independently arranged, the anchoring system can also not be independently arranged, and the platform assembly is integrally anchored.

The modular construction of semi-submersible offshore platform 100 and semi-submersible offshore swimming pool 200 is generally described below.

As shown in fig. 11-30, the modular construction of semi-submersible offshore platform 100 and semi-submersible offshore swimming pool 200, and the structural components common to both, are described in detail below.

Referring to fig. 11 to 29, the semi-submersible offshore floating platform with a modular space truss structure according to the preferred embodiment of the present invention includes a buoyant body, a semi-submersible buoyant body 10, a deck platform, and an anchoring system. Wherein, the semi-submerged buoyancy body 10 floats on the sea surface, and the deck platform is supported and arranged above the semi-submerged buoyancy body 10 through the lifting upright posts 3 and is used for placing a load 8 (the load here comprises various devices and mechanisms arranged on the deck platform and various loads temporarily placed/appeared on the deck platform). Meanwhile, the top of the buoyancy body is connected with the bottom of the semi-submersible buoyancy body 10 through the submergence upright post 9, and the buoyancy body is wholly submerged to a certain depth underwater to form a semi-submersible offshore platform. In addition, the bottom at the buoyancy main part is connected in the correspondence of anchoring system for realize the anchoring of buoyancy main part in the ocean bottom, avoid the buoyancy main part to be washed away by the wave, guarantee the stability that the buoyancy main part set up.

For the offshore platform in the preferred embodiment, the buoyancy of the buoyancy body should not be less than a buoyancy threshold, which may be defined as: when the buoyancy of the buoyancy body is set to be the buoyancy threshold value and the load on the deck platform is at the design limit state, the top of the semi-submersible buoyancy body 10 is just flush with the sea level. However, in actual installation, in order to avoid that the load on the offshore platform can meet stable use even when a small amount of load exceeds the limit load, the water level line of the offshore platform in the full load state is adjusted to the vertical middle level line of the semi-submersible buoyant body 10, so far, if the load on the offshore platform is further increased, the semi-submersible buoyant body 10 can also provide buoyancy by changing the draft.

Specifically, the buoyancy body in the preferred embodiment is formed by assembling a plurality of buoyancy modules which are sequentially connected and arranged in the horizontal direction and the vertical direction, and the buoyancy modules are sequentially assembled by a plurality of buoyancy adjustable points 1 which are arranged in a spatial array in the preferred embodiment.

As shown in fig. 17 and 18, the buoyancy adjustable points 1 in the preferred embodiment include, but are not limited to, two types, i.e., a first buoyancy adjustable point 101 and a second buoyancy adjustable point 102, each of which includes a spherical node buoyancy body and a plurality of horizontal connecting members 103 disposed on an outer circumferential ring of the node buoyancy body, and two vertical connecting members 104 disposed on upper and lower sides of the node buoyancy body, and the greatest difference is the difference in the number of horizontal connecting members 103 disposed on the outer circumferential ring. For example, in the preferred embodiment, the number of the horizontal connecting members 103 provided on the outer periphery of the first buoyancy adjustable point 101 is 6 at intervals, and the number of the horizontal connecting members 103 provided on the outer periphery of the second buoyancy adjustable point 102 is 4 at intervals. Meanwhile, the horizontal connecting members 103 are preferably arranged at equal intervals, that is, each horizontal connecting member 103 in the first buoyancy adjustable point 101 is arranged at an interval of 60 °, and each horizontal connecting member 103 in the second buoyancy adjustable point 102 is arranged at an interval of 90 °. Through the corresponding arrangement of the horizontal connecting pieces 103 at intervals, the corresponding assembly of the buoyancy modules with different cross-sectional shapes can be realized, so that different arrangement requirements and application requirements under different environments are met, for example, the buoyancy modules with hexagonal cross sections shown in fig. 13 and 14 and the buoyancy modules with quadrangular cross sections shown in fig. 15 and 16 are provided.

In addition, in the preferred embodiment, the nodal buoyancy body of the buoyancy-adjustable point is spherical, but it is apparent that the above-described structure is not the only arrangement form of the buoyancy body, and it may be also arranged in an ellipsoidal shape, a cylindrical shape, a quadrangular prism shape, a pentagonal prism shape, a hexagonal prism shape, an octagonal prism shape, or the like as needed in actual arrangement. Meanwhile, the diameter of the buoyancy adjustable point in the preferred embodiment is generally between 1 and 6m, and the diameter of the horizontal connecting member 103 and/or the vertical connecting member 104 is generally 150 to 1200 mm.

More specifically, the buoyancy adjustable point 1 in the preferred embodiment is a thin-walled hollow structure having a cavity formed therein, in which an elastic bladder 111 is disposed, as shown in fig. 19. Through the setting of elastic airbag 111, can be divided into inside and outside two parts with the cavity, note it as inboard cavity and outside cavity, inboard cavity wherein is preferred to be used for holding gas, and the outside cavity is used for holding the water, and through adjusting the mutual proportion of air inlet and exhaust volume, water inlet and exhaust volume in the casing, can adjust the buoyancy of this buoyancy adjustable point 1. Obviously, the positions of the gas and the water in the inner/outer cavities can be interchanged according to actual needs.

Further, an air inlet valve 108 and an air outlet valve 109 are arranged corresponding to the inner side cavity, one end of the air inlet valve 108 is communicated with an air source, the other end of the air inlet valve is communicated with the inner side cavity, one end of the air outlet valve 109 is communicated with the inner side cavity, and the other end of the air outlet valve is communicated with an air extraction device. The two air valves are one-way valves, and the adjustment of the volume of the elastic air bag 111 can be realized through the corresponding control of the two air valves. Correspondingly, a water inlet and outlet valve 110 is arranged corresponding to the outer cavity, one end of the water inlet and outlet valve is communicated with the outer cavity, the other end of the water inlet and outlet valve is communicated with the outer side of the buoyancy adjustable point 1, and the volume of the outer cavity can be adjusted by expanding or reducing the volume of the elastic air bag 111, namely, the water body in the outer cavity is automatically sucked or discharged, so that the buoyancy of the buoyancy adjustable point 1 is adjusted.

In a preferred embodiment, the buoyancy adjustment corresponding to the buoyancy adjustable point 1 is provided with an air supply adjusting mechanism, which is preferably arranged on the deck platform or directly on the buoyancy adjustable point 1 of the buoyancy body, and the air supply adjusting mechanism is communicated with the air inlet valves 108 of one or more buoyancy adjustable points 1 through pipelines. Of course, the intake valve 108 and the exhaust valve 109 of the preferred embodiment may be combined into one. In addition, a filtering mechanism can be correspondingly arranged at the outer end of the water inlet and outlet valve 110 to reduce solid impurities from entering the outer cavity.

Through the arrangement of the buoyancy adjustable points 1, the corresponding control of the buoyancy can be realized, when the peripheral wall surface of the elastic air bag 111 abuts against the inner side wall surface of the thin-wall hollow structure, the volume of the outer side cavity is minimum, and the buoyancy of the buoyancy adjustable points 1 is maximum; on the contrary, when the amount of gas in the elastic air bag 111 is small enough, the elastic air bag 111 is compressed to the limit, most of the thin-wall hollow structure is filled with water, and the buoyancy of the buoyancy adjustable point 1 is minimum. However, even if the ratio of gas and liquid in the buoyant body is adjusted, the actual configuration is not limited to the above-described specific configuration, and another configuration may be preferable as needed, and for example, in another preferred embodiment, the elastic bladder 111 may be eliminated, and the gas inlet/outlet adjusting mechanism and the liquid inlet/outlet adjusting mechanism may be provided separately for the buoyant body, and the gas-liquid ratio in the buoyant body may be directly adjusted, thereby adjusting the buoyancy.

Further, in the preferred embodiment, a single-layer buoyancy unit in a hexagonal shape may be formed by densely connecting a plurality of first buoyancy adjustable points 101 on a plane, and a buoyancy module in a hexagonal prism shape may be formed by connecting a plurality of layers of buoyancy units in a stacked manner in a vertical direction, as shown in fig. 13 and 14. Then, the arrangement of the buoyancy main body as shown in fig. 11 and 12 can be realized through the corresponding assembly of the plurality of buoyancy modules in the horizontal direction and the vertical direction. For the first buoyancy adjustable point 101, buoyancy modules formed after the first buoyancy adjustable point is correspondingly assembled are hexagonal prism structures, and a plurality of hexagonal prism structures can be assembled in a cylindrical surface connection mode and an end surface connection mode to form an integral buoyancy main body. Of course, for the second buoyancy adjustable points 102, they may be assembled to form a buoyancy module in a "quadrangular prism" structure.

For a single buoyancy module, it can be regarded as formed by correspondingly connecting a plurality of buoyancy bodies arranged in a dense array in space by using a space truss structure formed by a plurality of horizontal connecting members 103 and a plurality of vertical connecting members 104, and the buoyancy size of the buoyancy module is often determined by the number of buoyancy adjustable points 1 in the buoyancy module per unit volume and the buoyancy control of each buoyancy adjustable point 1. Meanwhile, the volume of the buoyancy module is often determined by the area of a single-layer buoyancy unit and the number of the arranged layers of the buoyancy units.

Specifically, the area of the single-layer buoyancy unit is determined by a horizontal node modulus l and the number S of unit nodes, wherein the horizontal node modulus l is the central distance after two adjacent buoyancy adjustable points 1 are connected; the number of unit nodes S is the number of buoyancy adjustable points 1 on each side of the buoyancy unit, and is 3 in fig. 13 and 5 in fig. 15. In actual arrangement, the closer the value of the horizontal node modulus is to the diameter of the buoyancy adjustable point 1, the greater the density of the buoyancy adjustable points in the single-layer buoyancy unit is, and the greater the buoyancy adjustable range of the correspondingly formed buoyancy unit is. According to the actual setting requirement, the buoyancy of the buoyancy unit can be adjusted by changing the distribution density of the buoyancy adjustable points 1 in the buoyancy unit, and the obtained buoyancy module is divided into a heavy-load buoyancy module, a medium-load buoyancy module and a light-load buoyancy module.

Furthermore, the plurality of layers of buoyancy units can be respectively connected in the vertical direction to form a buoyancy module with a certain volume. For example, the buoyancy modules in fig. 14 and 16 are respectively formed by vertically splicing four layers of buoyancy units. When vertical concatenation, the interval between two vertical adjacent buoyancy adjustable point 1 is perpendicular modulus h, under general condition, satisfying the prerequisite of production installation technological requirement, the value of perpendicular modulus should be close to the diameter of buoyancy adjustable point 1 as far as possible, can so that the intensive degree of buoyancy adjustable point 1 in vertical can fully guarantee, and then guarantees the buoyancy size of buoyancy module.

In actual setting, the number of the buoyancy units in a single buoyancy module is 2-8, and the buoyancy units can be optimized according to actual assembly and design requirements. Meanwhile, in the same offshore platform, the number of the buoyancy modules can be a plurality of buoyancy modules which are sequentially arranged in the horizontal direction or a plurality of buoyancy modules which are sequentially arranged in the vertical direction.

Further preferably, the buoyancy adjustable point 1 in the buoyancy body may also be partially replaced by a weight gain node, particularly preferably a spherical weight gain node. The weighted node in the preferred embodiment also comprises a thin-walled hollow shell within which is located a content of greater specific gravity than water to overcome buoyancy and increase self weight. Meanwhile, the weight-increasing nodes are often arranged at the bottom of the buoyancy main body and are preferably replaced at intervals in the circumferential direction, so that the center of gravity of the whole buoyancy main body is reduced, and the balance and stability of the whole offshore floating platform are improved.

As shown in fig. 21 and 22, in the preferred embodiment, a flexible connecting member 2 is provided corresponding to the horizontal connection of the buoyancy adjustable point 1, and is composed of a flexible connecting body 201 and flexible connecting flanges 202 provided at both ends of the flexible connecting body 201. The flexible connecting body 201 has certain radial, axial and circumferential deformability, and can realize the telescopic deformation (axial direction) of 15-50 mm and the transverse displacement (the direction intersecting the radial/axial direction) of 10-30 mm, and the rotational deformation (circumferential direction) within 15 degrees. Meanwhile, the flexible connecting member 2 may be used alone between the two buoyancy adjustable points 1, or a plurality of flexible connecting members 2 may be sequentially connected in series and then correspondingly used between the two buoyancy adjustable points 1 (for example, when two adjacent buoyancy modules are connected), as shown in fig. 25 and 26. In order to realize the quick connection of the buoyancy adjustable points 1, the horizontal connecting piece 103 in the preferred embodiment is a horizontal connecting flange, namely, two adjacent buoyancy adjustable points 1 in the horizontal direction are correspondingly connected through the flexible connecting piece 2, so that the displacement between the buoyancy adjustable points 1 in the same horizontal plane can be realized within a certain range, the buoyancy unit can better adapt to the environment of the action of sea waves, the acting force of the sea waves is fully buffered, and the setting stability of the offshore platform is ensured.

Correspondingly, two layers of stacked buoyancy units are directly connected through a vertical connecting piece 104, namely two vertically adjacent buoyancy adjustable points 1 are rigidly connected, so that the stress integrity of the buoyancy main body in the vertical direction can be fully ensured, and the level of each position of the buoyancy main body in the working process is ensured. After the setting is finished, the buoyancy module can be regarded as formed by sequentially and flexibly assembling a plurality of rigidly connected single-row buoyancy adjustable points 1 in a horizontal plane. In addition, two adjacent buoyancy modules are flexibly connected through a flexible connecting piece 2. In a preferred embodiment, the buoyancy adjustable points 1 in one and the same buoyancy module are connected by a single flexible connection 2, and the buoyancy adjustable points 1 between two adjacent buoyancy modules are connected by two flexible connections 2 connected in series, as shown in fig. 22. Meanwhile, two vertically adjacent buoyancy modules are directly connected through the vertical connecting member 104 of the buoyancy adjustable point 1, or are correspondingly connected through a flange connecting rod, for example, as shown in fig. 11, the buoyancy modules vertically arranged are two layers, and the two layers of buoyancy modules are rigidly connected through a flange connecting rod with a certain length. Obviously, whether the selected buoyancy adjustable point 1 is the first buoyancy adjustable point 101 or the second buoyancy adjustable point 102, the corresponding method for assembling the buoyancy body can refer to the above arrangement form, and finally form the buoyancy body with a certain volume.

Further, the semi-submersible buoyancy body 10 in the preferred embodiment is formed by flexibly splicing a plurality of buoyancy units in the horizontal direction, wherein the buoyancy units are flexibly connected through semi-submersible buoyancy nodes, and the buoyancy units can be spliced by using buoyancy adjustable points 1 which are the same as those in the buoyancy body, namely the buoyancy of the semi-submersible buoyancy body 10 is adjustable; of course, the buoyancy unit may be provided by selecting a buoyancy node having a structure different from that of the buoyancy adjustable point 1, for example, a buoyancy-unadjustable semi-submersible buoyancy node, that is, the semi-submersible buoyancy body 10 is provided in a buoyancy-unadjustable type, and the buoyancy of the spliced semi-submersible buoyancy body 10 is a fixed value.

Preferably, the semi-submersible buoyancy node in the semi-submersible buoyancy body 10 can also be partially replaced with a storage node, further preferably a spherical storage node as shown in fig. 30. The storage node is preferably a structural arrangement similar to the buoyancy adjustable point 1, which comprises a thin-walled hollow shell that is enlarged compared to the truss structure (horizontal 103 or vertical 104) for storing materials required for the operation of the offshore floating amusement equipment, including gaseous materials or liquid materials or solid materials. The storage nodes can reduce the center of gravity and improve the stability of the semi-submersible buoyancy body 10; make full use of the storage space of self, improved self-sustaining power and duration, and provided better closure, storage temperature stability need not to carry out frequent goods and materials through boats and ships and transports and supply.

When the storage nodes store gaseous materials, the storage nodes can be used for storing compressed gas, and each storage node can provide a gas source for buoyancy adjustment of one or more buoyancy adjustable points 1 on the buoyancy body. The structure of the storage node for storing compressed gas can be designed independently and can be similar to the buoyancy adjustable point 1, except that an elastic air bag, a water inlet and outlet port, a water inlet and outlet valve, a water inlet filter and the like are removed on the basis of the storage node, and an air inlet valve, an exhaust valve and the like are reserved. The air inlet valve can be communicated with the outside and is used for periodically supplementing the compressed air from the outside or supplementing the compressed air by a pipeline at proper time; the exhaust valve of the storage node for storing compressed gas is communicated with the intake valves 108 of the buoyancy adjustable points 1. By arranging the storage node for storing the compressed gas, the autonomous buoyancy adjustment can be completed without depending on external power and gas sources on the application occasion without frequently adjusting the buoyancy; the design of the gas supply and exhaust pipelines in the truss rod piece can be greatly simplified, and the maintenance difficulty is reduced.

When the storage node stores liquid materials, the liquid materials can be used for storing oil or fresh water, the oil can be used for the generator set, and the fresh water can be used for emergency use of the platform (can be supplied from the outside or can be collected from a seawater desalination device and natural rainfall through pipelines and then used for regurgitation). The structure of the storage node for storing liquid materials can be independently designed into a form as shown in fig. 30, a feed inlet and a discharge outlet are correspondingly arranged on the periphery of the storage node and used for external periodical supplement/discharge or timely supplement/discharge of pipelines for storing materials, and when the external periodical supplement is carried out, the storage node is preferably floated above the water surface.

When the storage node stores solid materials, the solid materials generally refer to solid particles such as grains and functional parts which can be conveniently added and extracted from the storage node. The structure of the storage node for storing solid materials can be independently designed into a form as shown in fig. 30, namely, the storage node comprises a feeding hole and a discharging hole and is used for external periodical supplement/discharge or pipeline timely supplement/discharge, and the external periodical supplement can be preferably performed when the storage node floats above the water surface.

In a semi-submersible offshore platform, the buoyancy body is entirely submerged below sea level and functions to provide the buoyancy required for the entire offshore platform, i.e., the load carrying capacity of the semi-submersible offshore platform is mainly provided by the buoyancy body. Accordingly, the semi-submersible hull 10 is not completely submerged below sea level when the heavy loads 8 on the offshore platform reach their limits, and functions to provide buoyancy for all or part of the fluctuating loads on the platform. If the load on the platform does not change greatly, the variable load can be provided with buoyancy through the change of the draft of the semi-submersible buoyancy body 10; if the load on the platform changes greatly and exceeds the bearing capacity of the semi-submersible buoyant body 10, the buoyancy of the buoyant body can be adjusted while the draft of the semi-submersible buoyant body 10 is changed, the buoyancy relative value of the whole buoyant body (the buoyant body and the semi-submersible buoyant body) is increased, and then buoyancy is provided for the changed load, so that the semi-submersible buoyant body 10 is ensured not to be immersed below the sea level. When the buoyancy of the buoyancy body is actually set, the buoyancy value is set to 70% -80% of the maximum value, so that the buoyancy can be correspondingly adjusted (increased or decreased) when the load of the offshore platform changes, and the adjustment of the buoyancy is realized by the buoyancy adjustment of the buoyancy adjustable point.

More specifically, the cross-sectional shape of the semi-submersible buoyant body 10 is preferably the same as that of the buoyant main body, for example, when the corresponding semi-submersible buoyant body 10 is assembled by using the first buoyancy adjustable points 101, the cross-sectional shape is the same as that of the buoyant main body in fig. 12, and in this case, the number of the buoyancy units is 7, and the whole structure is a "hexagon". Through the corresponding setting of semi-submerged buoyancy body 10, can greatly improve the security performance of whole semi-submerged formula platform. Moreover, because the semi-submersible buoyancy body 10 is arranged on the surge acting layer, the influence of the action of sea waves is obviously larger than that of the buoyancy body arranged below the sea level, and in view of the above, the preferred embodiment sets the semi-submersible buoyancy body 10 in a form of horizontally assembling single-layer buoyancy units, so that the acting area of the surge is reduced to a certain extent, and the action of the surge on the transversely swinging, heaving and swinging of the offshore platform can be reduced as much as possible. Of course, when actually setting up semi-submersible buoyancy body 10, its setting number of piles also can set up to the multilayer as required, and is 1 ~ 3 layers under ordinary conditions, and after offshore platform accomplished the setting, partial semi-submersible buoyancy body 10 salient in sea level, so, when the load on offshore platform changed, can make full use of semi-submersible buoyancy body 10 draft's change provide corresponding buoyancy.

Further, as shown in fig. 11, a deck platform is disposed above the semi-submersible buoyant body 10, which may be a unitary structure or may be formed by splicing a plurality of deck units 5. The semi-submersible buoyancy body 10 is correspondingly connected with the deck platform through a plurality of rising upright posts 3 which are vertically arranged, and the distance between the deck platform and a water line can be correspondingly adjusted through the optimization of the length of the rising upright posts 3, so that the wind and wave resistance of the platform is enhanced. During actual setting, the setting length of the lifting upright post 3 can be 2-20 m. Meanwhile, a submergence column 9 is arranged between the semi-submerged buoyancy body 10 and the buoyancy body, so that the buoyancy body can be submerged below the sea level, on one hand, the influence of a surge layer on the buoyancy body can be reduced, and the stability and the wind and wave resistance of the offshore platform are improved; on the other hand, after the buoyancy body is arranged below the sea level, the center of the whole offshore platform can be greatly reduced, and the stability and the wave resistance of the offshore platform are further improved. In actual installation, the installation length of the submerged column 9 is preferably 6-30 m according to the designed volume and the use condition of the buoyancy body.

Further, in the preferred embodiment, the rising column 3 and the submerged column 9 are identical in structure form, and as shown in fig. 23, flanges are respectively arranged at both ends of the rising column 3, and the arrangement of the rising column 3 between the deck platform and the semi-submersible buoyant body 10 and the arrangement of the submerged column 9 between the submerged buoyant body 10 and the buoyant body can be rapidly realized through the corresponding connection of the end flanges. In actual setting, the two ends of the submerged column 9 are rigidly connected respectively, and in order to ensure the stability of the deck platform, in a preferred embodiment, a vertical damping component 4 as shown in fig. 27 is further arranged between the rising column 3 and the deck unit 5, the vertical damping component 4 is provided with damping units which are arranged oppositely in the vertical direction, a spring which can be vertically stretched is arranged between the two damping units, then the two damping units can be connected with the bottoms of the rising column 3 and the deck unit 5 respectively, and the deck unit 5 is movably connected with the rising column 3, so that the stability of the deck platform when the buoyancy main body floats up and down due to the action of sea waves can be fully met, a part of vertical acting force from the buoyancy main body is buffered, and the working stability of the offshore platform is ensured. In addition, the rising upright column 3 and the submerging upright column 9 are preferably coaxially arranged in the vertical direction, and coaxiality and stability of load transmission are guaranteed.

Further, the mooring system in the preferred embodiment comprises mooring lines 6 and gravity anchors 7 arranged in correspondence of the mooring lines 6. One end of the mooring line 6 is connected to the bottom of the buoyant body and the other end is connected to the gravity anchor block 7. Through two gravity anchor blocks 7 sinking on the sea bottom surface, the arrangement of the offshore platform in the corresponding sea area of the deep and far sea can be realized, the offshore platform is prevented from being washed away by ocean currents and ocean currents, and the stability of the arrangement is ensured.

Specifically, in the preferred embodiment mooring lines 6 are attached at one end to vertical connectors 104 at the bottom of buoyancy adjustment points 1 and at the other end to gravity anchor blocks 7. The gravity anchor block 7 is as shown in fig. 28 and 29, and is preferably made of reinforced concrete, and comprises a block body 701 in a block structure, wherein the top of the block body 701 is provided with a mooring rope hanging lug 702 for connecting one end of a mooring rope 6; meanwhile, the bottom of the block 701 is provided with a plurality of grip teeth 704, and a front chamfer 703 is provided at one side of the block 701. With the arrangement of the ground gripping teeth 704, a reliable arrangement of the gravity anchor block 7 on the sea floor can be achieved, avoiding that the gravity anchor block 7 moves on the sea floor under the influence of deep ocean currents or sea bottom animals. In addition, anti-rollover bar members 705 are respectively arranged on two sides of the block body 701, so that rollover of the gravity anchor block 7 at the bottom of the ocean is avoided, and the stability of arrangement of the gravity anchor block 7 is further ensured.

In order to ensure the stability of anchoring at various positions of the bottom ring of the buoyancy body upwards, the gravity anchor blocks 7 in the preferred embodiment are arranged on the sea floor in a plurality, for example, when the planar shape of the buoyancy body is hexagonal, the number of the gravity anchor blocks 7 is 6, and the gravity anchor blocks are respectively arranged corresponding to the 6 buoyancy modules in the ring; and when the plane shape of the buoyancy body is rectangular, the number of the gravity anchor blocks 7 is 4 or 8 arranged in the circumferential direction at intervals. Accordingly, the mooring lines 6 connected to the respective gravity anchor blocks 7 are respectively connected at their ends to corresponding buoyancy modules in the bottom ring direction of the buoyant body, ensuring that the respective buoyancy modules in the bottom ring direction of the buoyant body are respectively connected to the mooring lines 6, as shown in fig. 12. Further preferably, each mooring line 6 forms a certain inclination angle with the seabed surface when being arranged, and the gravity anchor block 7 is positioned outside the area of the buoyancy main body facing the seabed surface, so that the stability of the offshore platform arrangement can be ensured by further utilizing the mutual restraint among the mooring lines 6.

Preferably, to further ensure the stability of the mooring line 6 when it is installed, in a preferred embodiment, the first buoyancy adjustable point 101 or the second buoyancy adjustable point 102 may be modified to a third buoyancy adjustable point 105 as shown in fig. 20, wherein in the third buoyancy adjustable point 105, a sealed mooring line channel 106 is provided between the two vertical connecting members 104 thereof, and the mooring line channel 106 communicates with the end faces of the two vertical connecting members 104 for the passage of one end of the mooring line 6. Correspondingly, mooring lines are provided in the rising column 3 and the submerged column 9, respectively, corresponding to the third buoyancy adjustable point 105, as described for the example of the rising column 3, the construction of which is shown in fig. 24, in which case the rising column 3 comprises a column 301 and end connections 302 provided at both ends of the column 301, which end connections 302 may preferably be flanges in the actual arrangement. Meanwhile, a mooring cable pipe 303 penetrating through two end faces is axially arranged in the middle of the column 301. Likewise, the submersible columns 9 may also be preferably configured as described above when configured.

In addition, in order to reduce the abrasion of the mooring line 6, an abrasion-proof connecting piece 107 is arranged at the bottom of the buoyancy body and can be correspondingly connected to the bottom of the third buoyancy adjustable point 105 at the bottom of the buoyancy body, so that the mooring line 6 can contact with a flat sliding piece at the bottom of the abrasion-proof connecting piece 107 after being straightened, and the flat sliding piece can be of a circular ring structure with a certain radian on the surface, namely, the contact part of the mooring line 6 and the buoyancy body is an arc surface, thereby reducing the degree of local abrasion.

Through the above arrangement, when the rising column 3, the semi-submersible buoyancy body 10, the submergence column 9 and the buoyancy main body are vertically and correspondingly connected, and the buoyancy adjustable points which are respectively coaxial with the two columns are the third buoyancy adjustable points 105, one end of the mooring cable 6 can sequentially penetrate through the mooring cable channels 106 in the buoyancy main body, the mooring cable pipeline in the middle of the submergence column 9, the mooring cable channels 106 in the semi-submersible buoyancy body 10 and the mooring cable pipeline 303 in the middle of the rising column 3, and finally penetrates through the deck unit 5 after penetrating out from the top of the mooring cable pipeline 303 until being connected with the corresponding anchor machine on the deck. Therefore, the mooring line 6 can be tightened or loosened by operating the anchor machine, so that the posture of the semi-submersible offshore floating platform can be adjusted. To achieve the above purpose, each buoyancy adjustable point 1 of the buoyancy body is spliced by using the third buoyancy adjustable point 105, or a single row of the third buoyancy adjustable points 105 is only vertically arranged at the connecting position of the mooring line 6.

Further preferably, in practical use, the buoyancy of the buoyancy adjustable point 1 located below the buoyancy body can be appropriately reduced, so that the center of gravity of the whole offshore platform is reduced, and the stability and wave resistance of the offshore platform are improved. As to how to specifically adjust the buoyancy of each vertically upward buoyancy adjustable point 1 of the buoyancy body, the optimization can be performed according to actual needs, for example, the buoyancy of the vertically single-row upper buoyancy adjustable point 1 can be sequentially reduced from top to bottom, or the buoyancy of the buoyancy module at the bottom of the buoyancy body can be reduced, or the buoyancy of several layers of buoyancy units at the bottom of the buoyancy body can be reduced, and the like.

In practical use, the working conditions of the semi-submersible offshore floating platform at least include the following conditions:

1. a normal low-load state in which the semi-submersible hull partially or fully protrudes above sea level;

2. in a normal high-load state, the draft of the semi-submersible floating body is increased, and the increased load on the deck platform and the buoyancy of the semi-submersible floating body are completely or partially offset; when the load on the deck platform reaches the design limit, the draught of the semi-submersible floating body becomes maximum, and the semi-submersible floating body is just completely immersed below the sea level;

3. exceeding the limit load state, in which the increased load on the deck platform is greater than the buoyancy of the semi-submersible floating body, and the draft of the semi-submersible floating body reaches the maximum (completely immersed in the seawater); in this case, the buoyancy of the entire offshore platform needs to be increased by adjusting the buoyancy of the buoyancy body (if the buoyancy of the semi-submersible floating body is adjustable, the buoyancy may be adjusted accordingly), and the semi-submersible floating body is adjusted to be above the sea level.

The first two states belong to the operation state of the offshore platform during normal operation, and the last state often occurs under the condition that the load on the deck platform is suddenly increased or part of the buoyancy adjustable points are invalid or the surging effect is too large, and at the moment, the offshore platform can be restored to the normal operation state through the buoyancy adjustment corresponding to the buoyancy adjustable points. Furthermore, if the offshore floating platform in the preferred embodiment is located offshore or at a small depth in the sea, the buoyant body may be submerged while ensuring that the deck platform is out of the water.

Further, for the offshore platform in the preferred embodiment, the steps when setting up may include the steps of:

(1) firstly, assembling a certain number of buoyancy modules on the shore or offshore with a certain water depth, and adjusting the buoyancy of the buoyancy modules to be maximum, namely the buoyancy modules have the minimum draft at the moment; meanwhile, the semi-submersible buoyancy body 10 with the corresponding size is assembled according to the design requirement, and if the semi-submersible buoyancy body 10 uses buoyancy adjustable points with adjustable buoyancy, the draught is adjusted to be the minimum;

(2) carrying out extension splicing in the horizontal direction and extension splicing in the vertical direction on each buoyancy module according to the setting requirement of the offshore platform to form a buoyancy main body with the minimum draft;

(3) materials such as the deck unit 5, the lifting upright posts 3, the vertical vibration reduction parts 4, the mooring ropes 6 and the gravity anchor blocks 7 are transported to the set sea area of the offshore platform by a barge, and the buoyancy body and the semi-submersible buoyancy body 10 can be towed to the target sea area in a towing manner during transportation.

(4) When the target sea area is reached, the buoyancy of the buoyancy adjustable point 1 in the corresponding buoyancy module can be adjusted to realize the adjustment of the overall buoyancy of the buoyancy main body, and the top of the buoyancy main body can be slightly higher than the sea level; then, connecting one end of each submerged upright post 9 to a corresponding position on the buoyancy main body until the connection arrangement of the bottom of each submerged upright post 9 is completed;

(5) further adjusting the buoyancy of the buoyancy body to enable the buoyancy body to sink in the seawater, hovering the buoyancy body at the ocean depth when the buoyancy body submerges to a preset position, namely the top of the submerging upright post 9 is just submerged below the sea level, wherein tension ropes can be respectively arranged on the periphery of the top of the buoyancy body to ensure reliable hovering of the buoyancy body, and reliable hovering of the buoyancy body is realized by pulling of a ship;

(6) dragging the semi-submersible buoyancy body 10 to the position right above each submersible upright post 9 to realize the rigid connection between the bottom of the semi-submersible buoyancy body 10 and the submersible upright posts 9; thereafter, the lifting columns 3 are correspondingly arranged at the tops of the semi-submersible buoyancy bodies 10, the deck units 5 are assembled into a deck platform of an integral structure, and then the bottoms of the deck platform are correspondingly connected with the tops of the lifting columns 3. Obviously, the deck platform can be connected with each rising upright post 3 after being correspondingly spliced, or can be connected with each rising upright post 3 at the corresponding position of each deck unit 5 before splicing each deck unit 5 into an integral structure.

(7) And adjusting the buoyancy of the buoyancy main body to a preset value, and arranging an anchoring system consisting of a gravity anchor block 7 and a mooring line 6 corresponding to the buoyancy main body to realize the fixation of all the positions of the periphery of the bottom of the buoyancy main body and complete the arrangement of the main body structure of the semi-submersible offshore floating platform.

(8) Corresponding equipment or mechanisms are arranged on the deck platform to complete the functional setting of the offshore platform, so that the offshore platform can work normally and stably.

Obviously, compared with the method that the buoyancy main body needs to be assembled in advance in a shipyard and then transported to a target sea area through a large barge in the traditional offshore platform setting process, the transportation mode has great convenience. Moreover, during actual setting, the buoyancy adjustable points 1 can be spliced into a plurality of buoyancy modules firstly, and the buoyancy modules are dragged to the target sea area and then spliced.

In addition, the transportation of the deck unit 5, buoyancy modules and the like can be performed in a towering manner, which can avoid the use of large ships. Specifically, after the buoyancy modules are assembled, the deck units 5 can be briefly fixed above the buoyancy modules, and the assembled combined structure of the buoyancy modules and the deck units is subjected to towing operation, so that the use of large ships can be reduced, after the assembled combined structure is towed to a target sea area, the buoyancy modules can be assembled into a whole, then the deck units 5 are detached, and the assembled structure above the sea level is assembled after the upright columns 3 are lifted.

In addition, when the height of the buoyancy main body in the vertical direction is large and transportation is performed in a towing manner, the buoyancy main body can be horizontally towed after being turned for 90 degrees in the transportation process, that is, each vertical connecting piece 104 of each buoyancy adjustable point 1 is switched from the vertical direction to the horizontal direction, and the buoyancy of each buoyancy adjustable point 1 is adjusted to the maximum (the draught is minimum). So set up, can bring abundant facility for the dragging of buoyancy main part, guarantee efficiency and the stability of dragging. And (3) after the buoyancy main body is towed and transported to a target sea area, changing the gravity center position of the buoyancy main body by adjusting the buoyancy in the buoyancy adjustable point at the corresponding position, realizing the adjustment of the draft of the buoyancy main body in the seawater and the overturning of the set direction, and finally adjusting the buoyancy design value and the set direction of the buoyancy main body. However, considering the horizontal flexible connection between the buoyancy adjustable points 1, before the buoyancy main body is turned for 90 degrees, a plurality of horizontal connecting rods can be arranged at the top and the bottom of the buoyancy main body respectively, and the horizontal connecting rods are correspondingly connected with the vertical connecting pieces of the buoyancy adjustable points at the top, namely, the buoyancy adjustable points 1 in each line are rigidly connected together, so that the displacement between the buoyancy units in each vertical layer after turning and the damage to the flexible connecting pieces are avoided.

Furthermore, when actually towing the buoyancy main body, the buoyancy modules after being assembled can be sequentially arranged in series, the buoyancy main body after being arranged in series is towed to a target sea area, the connection of the corresponding buoyancy modules is removed at the target sea area, the draft of the buoyancy modules is adjusted by adjusting the buoyancy of the corresponding buoyancy modules, and then the connection of the buoyancy modules in the vertical direction is completed until the whole buoyancy main body is arranged.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
