The work platform 2 can be used for carrying out various offshore activities such as marine exploitation, marine product production or living, entertainment and the like. Under normal sea conditions, when draught is located in the main floating body frame 1, an offshore operation platform is formed on the upper surface of the main floating body frame 1, water surface operation activities can be conveniently carried out, a safe guarantee space is formed by the main floating body frame 1 and the lower frame body 3 which are of annular structures, and appropriate underwater production operations and other underwater operation activities can be carried out in the lower frame body 3. The ocean economy development basic platform module of the embodiment can be used for conveniently carrying out operation activities on the water surface, on the water surface and under the water surface at the same time, and a multi-layer three-dimensional collaborative development ocean economy development mode with complementary advantages is formed.
Furthermore, a first supporting platform can be arranged in the annular space of the main floating body frame 1, and a second supporting platform is arranged in the annular space of the lower frame body 3, so that a more convenient offshore and undersea operation platform with a larger supporting area is formed. Specifically, the supporting platform in the annular space of the main floating body frame 1 and the lower frame body 3 can be hollowed out, so that seawater and sea waves can penetrate through the gap, and the impact on the basic platform module is offset and relieved.
The operation platforms 2 and the lower frame body 3 can be provided with a plurality of connecting columns 4 and arranged along the axial direction, two adjacent operation platforms 2 are connected through the first connecting columns 4, and two adjacent lower frame bodies 3 are connected through the second connecting columns 5. As the number of the work platforms 2 and the lower frames 3 increases, the radial dimension of the annular structure of the main floating body frame 1 increases. The number of the operation platforms 2 and the lower frame body 3 is increased, the number of the offshore operation platforms and the number of the offshore operation platforms can be increased, the operation platforms are of a stacked type, a floor type operation space is provided, operation activities with various different contents can be conveniently and rapidly carried out in the same sea area, the operation activities with various different contents respectively have independent operation platforms, extremely high space operability and convenience for development, and remarkable economic effects are achieved for development of offshore economic development.
The first connecting column 4 and the second connecting column 5 are both provided with a plurality of connecting columns which are distributed along the circumferential direction of the main floating body frame 1 so as to provide stable connection and stable support. One end of the first connecting column 4 is connected with the columnar floating body 101, the other end is connected with the operation platform 2, the radial dimension of the first connecting column 4 can be gradually reduced along the direction from the main floating body frame 1 to the operation platform 2, and the first connecting column 4 can be in a step-shaped structure or continuously reduced to enable the first connecting column 4 to be in a conical structure. Or as shown in fig. 2, the radial dimension of the first connecting column 4 may be a structure that is large in the middle and small in both ends along the axial direction of the first connecting column 4, that is, a convex ring is arranged at the middle position of the axial direction, the radial dimension of the convex ring is greater than the radial dimensions of the other positions, and the convex ring and the other parts of the first connecting columns 4 at both sides of the convex ring are in fillet transition, so that the radial dimension of the first connecting column 4 is changed, so as to set, when the waterplane is located on the first connecting column 4 by adding a ballast manner under a storm sea condition, the basic platform module has a function of adjusting the waterplane size according to the sea condition: the location of the water surface on the first connector post 4 may be selected for additional ballast as the case may be so that the size of the water surface is determined by the radial dimension of the first connector post 4 at that location.
Since the main floating body frame 1 bears the main buoyancy, the radial size of the columnar floating body 101 is large. The radial dimensions of the second connecting post 5 can be made the same as the first connecting post 4: the radial dimension of the second connecting column 5 is gradually reduced along the direction from the main floating body frame 1 to the lower frame body 3.
Specifically, the ring structures of the main floating body frame 1 and the lower frame 3 may be circular rings or polygonal rings. If a polygonal shape is used, preferably a hexagonal shape as shown in fig. 2, a larger space area can be occupied and the structural stability can be optimized. Specifically, the cylindrical floating body 101 may be a hollow column tube made of steel or a waterproof composite material. Preferably, the columnar floating body 101 is made of hollow column pipes and has a hollow structure, so that the columnar floating body can have a large section size under the same weight, the waterplane area or the water discharge can be increased, and the stability of the frame can be enhanced; further, the radial section of the cylindrical floating body 101 is rectangular or polygonal so that the cylindrical floating body 101 has two levels parallel to the sea surface, which can further increase the water level and enhance the stability compared to the case that the section is circular. The inner space of the columnar floating body 101 can be utilized and set into a cabin structure, and a plurality of cabins can be distributed along the circumferential direction of the columnar floating body 101 and used as different functional areas, such as storage areas of ballast water, fresh water or oil, mechanical cabins and the like.
As shown in fig. 2, the work platform 2 may adopt an integrated platform structure, and the upper end surface of the platform is used as an offshore work platform layer for supporting and connecting various functional structures for offshore work activities, such as upper buildings, and the like, and the interior of the work platform 2 may be a hollow structure, and the space thereof may be specifically utilized according to functional requirements, such as hotel and the like. The axial upper end of the first connecting column 4 is connected with the lower end face of the platform, and the lower end is connected with the columnar floating body 101. As shown in fig. 3, the work platform 2 may include an upper frame 201 and an integrated platform laid over the upper frame 201. Preferably, the upper frame 201 has a ring structure, and the ring shape of the upper frame 201 may be the same as the ring shape of the main floating frame 1. The upper end of the first connection column 4 is connected to the upper frame 201, and the lower end is connected to the columnar floating body 101. The upper frame 201 is formed by a rod member having an annular structure, a support rod 202 is disposed in the annular space, and two ends of the support rod 202 are connected to different positions of the inner wall of the annular space. The plurality of support rods 202 can be uniformly arranged along one direction, can also be arranged along two mutually perpendicular directions to form a net structure, and can also extend along the radial direction of the annular space to form a structure which is crossed at the center of the annular space. Each support rod plays a role in supporting and stabilizing the integrated platform. The upper frame 201 and the support rods 202 may be formed of hollow rods or floats to provide a reserve buoyancy in severe sea conditions. When the annular space of the annular structure is circular, the radial direction of the annular space refers to the diameter direction of the circle; as shown in fig. 3, when the annular space has a polygonal shape, the radial direction of the annular space refers to the diameter direction of the circumscribed circle of the polygonal shape, i.e., the diagonal direction of the polygonal shape.
The first support platform may be a platform layer of a unitary structure, laid in the annulus of the main float frame 1, or, as shown in fig. 3, provided with reinforcing floats 102 connecting the inner walls of the columnar floats 101 at different locations. The reinforcing floating bodies 102 are multiple and can be uniformly arranged along one direction, or arranged along two mutually perpendicular directions to form a net structure, or can be structures which extend along the radial direction of the annular space and intersect at the center of the annular space. Each reinforcing floating body 102 forms a hollow first supporting platform and can play a role in enhancing the strength of the frame, enhancing the impact resistance of the columnar floating body 101, increasing the waterplane area and the reserve buoyancy of the main floating body frame 1, and improving the stability of the module.
Similarly, as shown in fig. 3, the lower frame 3 is formed of an annular floating body in an annular shape, and the second support platform is formed of a plurality of connection floating bodies located in the annular space, both ends of the connection floating bodies being connected to the inner wall of the annular space at different positions. Each connecting floating body can be uniformly arranged along one direction, can also be arranged along two mutually perpendicular directions to form a net structure, and can also extend along the radial direction of the annular space to form a structure crossed at the center of the annular space. Each connecting floating body can be used as an undersea hollow-out type supporting platform for undersea operation; but also increases the displacement, enhances the structural strength and stability. Or, in order to increase the supporting area of the supporting platform, a supporting layer can be laid in the annular space of the lower frame body 3 and above each connecting floating body, and the supporting layer is of a hollow structure, such as a steel mesh, so as to form the supporting platform of the lower frame body 3 and be used as an underwater operation platform. And the supporting platform in the annular space of the main floating body frame 1 can be designed in the same structure.
Preferably, the reinforcing float 102, the support rods 202 and the connecting floats are all in a configuration extending radially of the annulus, intersecting at the center of the annulus. Therefore, cross connection points among the floating bodies can be reduced, the strength reduction caused by excessive connection points is avoided, and a stable point can be formed at the center of the annulus.
Then, in order to reduce the span between each first connection column 4 and each second connection column 5, there may be auxiliary connection columns between the main floating body frame 1 and the working platform 2, and between the main floating body frame 1 and the lower frame 3. For example, a diagonal brace with two ends respectively connected with the first connecting column 4 and the upper frame 201 is arranged between the first connecting column 4 and the upper frame 201, and a diagonal brace with two ends respectively connected with the second connecting column 5 and the columnar floating body 101 is arranged between the second connecting column 5 and the columnar floating body; or, connecting columns with smaller radial size extending along the axial direction of the first connecting column 4 can be arranged between the supporting rod 202 and the reinforcing floating body 102 and between the connecting floating body and the reinforcing floating body 102 to enhance the longitudinal connection strength of the frame, and the connecting columns can be positioned at the circle center of the annulus and are crossed and connected with the cross points of the floating bodies at the circle center of the annulus.
The annular floating body, the upper frame body 201, the reinforcing floating body 102, the support rod 202, the connecting floating body, the first connecting column 4, the second connecting column 5 and the auxiliary connecting column are all made of hollow column tubes and are in hollow structures, so that the annular floating body has large section size under the same weight or has smaller structural weight under the same section size. The reinforced float 102 may increase the waterplane, displacement, reserve buoyancy and enhance the stability of the frame; the large cross-sectional dimensions of the upper frame 201 and the support rods 202 can increase the area of the working platform layer and provide a larger offshore working space; the large section size of the annular floating body and the connecting floating body can increase the displacement and the stability, and water can be injected into the cavities of the annular floating body and the connecting floating body according to the requirement under certain sea conditions to increase the load so as to lower the whole foundation module platform; the hollow structure of the first connecting column 4, the second connecting column 5 and the auxiliary connecting column can reduce the total weight of the structure. The cross-sectional shape of the vial is not limited to circular but may be rectangular or polygonal.
And the connection among all the parts can adopt a welding mode, so that the whole frame has high strength.
