Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The invention provides an offshore assembled buoyancy tank platform, which comprises a plurality of buoyancy tanks and connecting devices, wherein the buoyancy tanks are arranged on the offshore assembled buoyancy tank platform; the buoyancy tank and the connecting device are used in a matched mode, and are different from the traditional buoyancy tank, and the buoyancy tank and the connecting device are independent.
As shown in fig. 1, the buoyancy tank body 1 is provided with a groove at the periphery thereof for engaging with the connecting device, and the groove is divided into a horizontal connecting seat 2 and a vertical connecting seat. The adjacent floating boxes are connected transversely and longitudinally through the connection device and the groove in a clamping mode.
As shown in fig. 2, the connecting device includes a housing 5, a triangular top block 3, a joint 4 and a hydraulic system. The hydraulic system adopts a bidirectional oil cylinder.
The shell 5 is in a frame form, and two opposite side surfaces of the shell 5 are provided with joint slideways which are communicated with the outside; the triangular top block 3 is arranged inside the shell 5, and the triangular top block 3 is in sliding fit with the joint 4; flotation tank I links firmly through connecting device with flotation tank II, and connecting device one side flotation tank I links firmly, and the opposite side and flotation tank II with link firmly, connecting device height is unanimous with flotation tank thickness, is covered with whole flotation tank height. Taking the internal structure of the connecting device at the connecting side of the buoyancy tank I as an example, a triangular top block 3 is matched with two connectors 4; the two triangular jacking blocks 3 respectively move towards two ends of the shell 5 under the driving of a hydraulic system to drive the joint 4 to extend out or retract in a joint slideway, and the joint slideway is vertical to the moving direction of the triangular jacking blocks 3; the joint 4 is used for being clamped with the groove, and the extending end of the joint 4 is a spherical surface.
The triangular top block 3 is provided with a T-shaped dovetail groove along the inclined plane; and a T-shaped rail 6 which is in sliding fit with the T-shaped dovetail groove is arranged on the joint 4. The T-shaped rail 6 is hinged with the joint 4.
In the use process, the upper joint 4 and the lower joint 4 are connected with the corresponding transverse connecting seat 2/longitudinal connecting seat of the buoyancy tank body 1, and under the action of wind and wave flow under a high sea condition, the whole joint 4 is simultaneously subjected to the actions of pressing, shearing and bending moment. The connecting device adopts a hydraulic pump station as a hydraulic power source, and an inner interface of a groove on the upper part of the connecting device shell 5 can be quickly connected with the pump station through a quick connector. As shown in fig. 3, (1) and (2) are respectively in an extending state and a retracting state, the extending of the joint 4 is realized by pushing the triangular ejecting block 3 through the bidirectional oil cylinder, the inclined plane of the triangular ejecting block 3 pushes the inclined plane of the joint 4 to extend, and the joint is automatically locked by a hydraulic lock after the connecting seat corresponding to the buoyancy tank body 1 is connected in place; as shown in fig. 4, when the joint 4 is retracted, the T-shaped rail 6 of the joint 4 is in sliding fit with the T-shaped dovetail groove of the triangular top block 3, and when the bidirectional oil cylinder is retracted, the triangular top block 3 drives the joint 4 to retract. In order to prevent the T-shaped rail 6 of the joint 4 from being locked with the T-shaped dovetail groove of the triangular top block 3, as shown in fig. 5, the T-shaped rail 6 of the joint 4 is hinged to the opposite side of the extending end of the joint 4 through a pin shaft, and the angle can be automatically finely adjusted.
