The connection structure between these modular platforms is crucial to the modular design. Traditional connection methods, such as welding, require manual intervention for locking, are complex to operate, have low automation, and lead to low operational efficiency, long work cycles, and increased costs.

[0032] Example

[0033] This embodiment provides a connection and locking device for a modular offshore platform. See [link / reference] Figure 1 It includes a first connecting component 1 and a second connecting component 2. The first connecting component 1 is disposed on the platform body, and the second connecting component 2 is disposed on an adjacent platform body. The first connecting component 1 and the second connecting component 2 cooperate and are locked together by a locking connecting component 3.

[0034] Preferred, see Figure 1 and Figure 5 The first connecting component 1 includes a concave connecting structure, which includes a first connecting seat 1.1 and a concave groove 1.2 disposed on the first connecting seat 1.1; the first connecting seat 1.1 is connected to the platform body; the second connecting component 2 includes a convex connecting structure, which includes a second connecting seat 2.1 and a boss 2.2 disposed on the second connecting seat 2.1; the second connecting seat 2.1 is connected to the platform body; the boss 2.2 matches the concave groove 1.2, and when the concave connecting structure and the convex connecting structure are connected, the boss 2.2 and the concave groove 1.2 are mutually engaged.

[0035] Preferably, the two opposite sides of the boss 2.2 are set as tapered surfaces, and the two opposite sides of the concave groove 1.2 are also set as tapered surfaces. The tapered surfaces of the boss 2.2 and the concave groove 1.2 match. By setting the tapered surfaces, a guiding effect can be formed, which facilitates the rapid docking of the concave connection structure and the convex connection structure. At the same time, the cooperation of the tapered surfaces can realize the longitudinal bending resistance and the lateral torsion resistance between adjacent platforms.

[0036] See Figure 2The locking connection assembly 3 is disposed in the internal cavity of the convex connection structure. The locking connection assembly 3 includes a locking block 3.1 and a driving device 3.2. The driving device 3.2 drives the locking block 3.1 to lock the concave connection structure and the convex connection structure.

[0037] In this embodiment, the driving device 3.2 includes a hydraulic cylinder 3.2.1. A cylinder base is fixed inside the internal cavity of the boss 2.2. The fixed end of the hydraulic cylinder 3.2.1 is fixed to the cylinder base. The piston rod of the hydraulic cylinder 3.2.1 is connected to the push rod 3.2.2, driving the push rod 3.2.2 to reciprocate. The movement direction of the push rod 3.2.2 is perpendicular to the movement direction of the locking block 3.1. A wedge block 3.2.3 is provided on the push rod 3.2.2, and the wedge block 3.2.3 slides in cooperation with the locking block 3.1.

[0038] In this embodiment, preferably, the wedge block 3.2.3 is a triangular apex block, the locking block 3.1 is a spherical connector, and the two inclined surfaces of the triangular apex block slide in contact with the spherical surface of the spherical connector.

[0039] In this embodiment, see Figure 2 The boss 2.2 has two opposite sides (i.e. two conical surfaces on the boss) symmetrically provided with slides 2.3, which are connected to the outside; the spherical connector is disposed in the slide 2.3, and the driving device 3.2 drives the spherical connector to extend or retract in the slide 2.3.

[0040] See Figure 4 and Figure 5 The concave groove 1.2 is symmetrically provided with sliding grooves 1.3 on two opposite sides, and the sliding grooves 1.3 match the locking block 3.1; after the boss 2.2 is assembled with the concave groove 1.2, the axis of the slide 2.3 and the sliding groove 1.3 coincides.

[0041] In this embodiment, four slide rails 2.3 are provided, symmetrically arranged on two conical surfaces of the boss; correspondingly, four sliding grooves 1.3 are provided, symmetrically arranged on two conical surfaces of the concave groove 1.2. After the boss and the concave groove 1.2 are assembled, the slide rails 2.3 and the sliding grooves 1.3 correspond one-to-one; four spherical connectors are provided accordingly. Preferably, an elastic connecting device, such as a spring, is provided between the spherical connector and the slide rail 2.3. The triangular apex moves and contacts the spherical connector, pushing the spherical connector to move along the slide rail 2.3, extend and enter the sliding groove 1.3, realizing the locking connection between the boss and the concave groove 1.2. Figure 4 When the triangular apex moves and does not contact the spherical connector, the spherical connector resets under the action of the spring, disconnecting the connection between the boss and the concave groove 1.2.

[0042] In this embodiment, preferably, there is one hydraulic cylinder 3.2.1, and wedges 3.2.3 are fixedly provided at both ends of the push rod 3.2.2. The wedges 3.2.3 are coaxially arranged with the push rod 3.2.2, and the two wedges 3.2.3 are arranged in the same direction. The push rod 3.2.2 is connected to the piston rod of the hydraulic cylinder 3.2.1 through a support plate. See [reference needed] Figure 3 When the piston rod extends, it drives the push rod to move upward, which in turn drives the two wedges 3.2.3 to move upward. The two wedges 3.2.3 push the four locking blocks 3.1 to extend out of the boss 2.2 and lock into the concave groove 1.2.

[0043] As another preferred technical solution, the hydraulic cylinders 3.2.1 are configured as two, and each hydraulic cylinder 3.2.1 controls one push rod to drive one wedge block 3.2.3 to move up and down, so as to realize the locking connection between the concave connection structure and the convex connection structure.

[0044] In this embodiment, see Figure 2 and Figure 5 The boss 2.2 is internally provided with a locking pin 3.3, which is perpendicular to the push rod 3.2.2. The push rod 3.2.2 is provided with a locking slot 3.4, and the locking pin 3.3 cooperates with the locking slot 3.4 to lock and limit the push rod 3.2.2. When the push rod 3.2.2 moves upward under the drive of the hydraulic cylinder 3.2.1, the wedge block 3.2.3 also moves upward under the drive of the push rod 3.2.2, thereby pushing the locking block 3.1 to extend. When the push rod 3.2.2 has reached its travel limit, the locking pin 3.3 and the locking slot 3.4 cooperate to lock and limit the push rod 3.2.2, preventing the wedge block 3.2.3 from moving and causing the locking device to fail, thus increasing the reliability of the locking device.

[0045] In this embodiment, see Figure 5 and Figure 6 The locking pin 3.3 includes a pin body 3.3.1, one end of which is connected to a beveled connecting block 3.3.2, and the other end is connected to the top of the inside of the boss 2.2 via a spring. The axis of the pin body 3.3.1 is perpendicular to the axis of the push rod 3.2.2. The connecting block 3.3.2 engages with the locking lug 3.4. During the upward movement of the push rod 3.2.2, the top of the push rod 3.2.2 slides against the connecting block 3.3.2. When the spring is compressed, the push rod 3.2.2 moves to its maximum position. When the spring reaches its maximum position, the locking port 3.4 aligns with the connecting block 3.3.2. The connecting block 3.3.2 is pushed into the locking port 3.4 under the action of the spring, thus locking and limiting the push rod 3.2.2. By setting an inclined surface on the connecting block 3.3.2, it is beneficial for the push rod 3.2.2 and the connecting block 3.3.2 to slide into and out of the locking port 3.4.

[0046] The connection structure provided by this utility model is simple in structure and easy to operate. In particular, the connection between adjacent platform bodies can be realized by driving the locking block to extend and retract through the driving device, without the need for manual operation. It has a high degree of automation, improves work efficiency, and thus reduces costs.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
