The entire adjustment process generally includes: offshore towing and shifting, offshore operation platform in place, pile legs extending into the seabed to find support, the platform body rising off the sea surface, and drilling construction.

Specifically, it is impossible to intuitively simulate the flow rate of seawater through the equipment, making it impossible to obtain the platform's ability to prevent rollover in the sea. In addition, it is impossible to simulate the platform's drilling and settlement conditions under different geological conditions, making it impossible for the entire simulation process to provide more intuitive parameters.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0027] Reference Figure 1-3 An embodiment of the utility model provides an offshore platform lifting control simulation system, comprising:

[0028] A pumping assembly 1, a water tank 2, and a drain port 3 connected to two opposite sides of the water tank 2. The water tank 2 is used to hold water to simulate the situation in the ocean. The pumping assembly 1 is used to pump water between the two drain ports 3. The two drain ports 3 can be connected through a pipeline. The pumping assembly 1 can adopt a structure such as an electric drive propeller, which can be set in the drain port 3 or in the pipeline.

[0029] A hanging frame 4 fixedly arranged relative to the water storage tank 2 and a plurality of pressure sensors 5 connected to the hanging frame 4, wherein the hanging frame 4 is located directly above the plane of the water storage tank 2;

[0030] A platform model 6, a pile model 7 arranged on the platform model 6, and a connecting frame 8 vertically slidably connected to the platform model 6, the platform model 6 and the pile model 7 together constitute a model structure of the construction platform, the connecting frame 8 is connected to a plurality of pressure sensors 5, and the plurality of pressure sensors 5 are evenly distributed in different directions in the horizontal direction;

[0031] Based on the above, when simulating the situation of an offshore platform in the ocean, the utility model installs a soil structure for simulating the seabed foundation at the bottom of the water tank 2, and fills the water tank 2 with water of appropriate depth, and the offshore platform model 6 is immersed in water. Through the vertical sliding between it and the connecting frame 8, the entire model sinks under the action of gravity, so that the bottom of the pile model 7 falls on the foundation model, thereby simulating the platform standing on the seabed, and the pumping component 1 is used to create a liquid flow effect, so that the water flows in from one of the drain ports 3 and is discharged from the other drain port 3, thereby forming a cycle, so that a unidirectional water flow is formed in the water tank 2, thereby simulating the flow of seawater. Based on this, the utility model can simulate the following parameters of the entire offshore platform model 6 when facing real ocean conditions:

[0032] The flow effect of the water flow in the water tank 2 causes a lateral impact on the model. At this time, the connecting frame 8 is subjected to a lateral breaking force on the hoisting frame 4, so that the forces between the multiple pressure sensors 5 are uneven. By observing the difference between the multiple force values, the degree of the roll force on the entire offshore platform model 6 can be obtained. The data results can be used for personnel to analyze whether the platform can ensure sufficient stability when facing this situation in the sea in actual situations;

[0033] In the case of non-water flow simulation, by obtaining the numerical difference between the multiple pressure sensors 5, it is possible to know the difference in settlement degree between the pile models 7 when they are located in different geological conditions, so as to allow personnel to analyze whether the platform can ensure sufficient stability when facing such actual geological conditions;

[0034] By observing the overall numerical conditions of the multiple pressure sensors 5, the gravity conditions of the model can be known, that is, the overall settlement of the entire platform model 6 can be analyzed, thereby obtaining the influence of the seabed with different degrees of softness on the stability of the platform;

[0035] To further facilitate reading of the value of the pressure sensor 5, the utility model can also be configured with a display module, such as a display or a computer, and the pressure sensor 5 can be connected to the display or computer, thereby facilitating an intuitive display of the value.

[0036] Further, see Figure 1-5 Regarding the connection method between the platform model 6 and the connecting frame 8, a vertical sleeve 9 is constructed on the platform model 6, and a part of the connecting frame 8 is an insertion rod 801, which is spline-connected to the sleeve 9. Specifically, the sleeve 9 is spline-mounted on the insertion rod 801, so that a vertical sliding relationship is formed between the platform and the connecting frame 8 to ensure the stability of the entire platform model 6.

[0037] Further, see Figure 1-3 In order to ensure the relative fixed stability between the hanging frame 4 and the water tank 2, the hanging frame 4 can be directly fixedly connected to the water tank 2. Specifically, the hanging frame 4 is fixedly connected to the water tank 2 through at least two connecting bridges 10, and the two connecting bridges 10 are symmetrically distributed in position, so that the hanging frame 4 is erected above the water tank 2, while ensuring a certain stability effect.

[0038] Further, see Figure 4 The connecting frame 8 also includes a plurality of supporting legs 802 integrally connected to the insertion rod 801, and the plurality of supporting legs 802 are distributed in a circular array. The plurality of pressure sensors 5 are respectively connected to the plurality of supporting legs 802, and the insertion rod 801 is located in the central area of ​​the plurality of supporting legs 802, so that when the insertion rod 801 is subjected to force, the force can be quickly and evenly distributed to the plurality of pressure sensors 5.

[0039] Further, see Figure 5 The pile model 7 movably penetrates the platform model 6, and can slide vertically on the platform model 6 and rotate at the same time. A driving motor 11 is fixedly arranged on the platform model 6, and a driving rod 12 is connected to its output end. The driving rod 12 is movably inserted in the pile model 7 and is splined with the pile model 7. The driving motor 11 controls the driving rod 12 to rotate, so that the rotation of the pile model 7 can be controlled, so that it can simulate the situation of piling in the sea.

[0040] Further, see Figure 1 and Figure 2The space inside the water tank 2 includes a first area 201 and two second areas 202 located on both sides of the first area 201 in the horizontal direction. A barrier 13 is provided between the first area 201 and the second area 202 to separate the three areas. The first area 201 is used to load the foundation model, that is, to load the soil blocks simulating the actual situation of the seabed. Through the action of the barrier 13, the water flow is not easy to impact the soil blocks when flowing in the lower layer, so as to not easily cause the soil to escape in the water. The barrier 13 can be a partition, and its height can be slightly half of the depth of the water tank 2, so as not to hinder the upper water flow, and at the same time play a blocking effect on the soil blocks in the lower layer.

[0041] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
