A platform connection device for large-scale deep-sea fishing grounds

Abstract

The invention discloses a connecting device for a deep-sea large-scale fishing ground platform, which comprises at least three damping devices and at least two X-shaped anchor chain devices arranged between two fishing ground platforms; Two pistons at both ends of the spherical connecting rod, a cylinder matched with the piston, and two connecting and fixing members, both ends of the spherical connecting rod can freely rotate in the piston, and the X-shaped anchor The chain device includes two anchor chains arranged crosswise, the two ends of the anchor chains are respectively connected with the fixing parts, and the fixing parts are fixedly connected with the upper surface of the fishing ground platform. The structure of the connection device for large-scale deep-sea fishing grounds disclosed by the present invention is optimized, with remarkable effect, long service life, safety and high efficiency. Compared with the traditional connection device for fishing grounds, it tends to be mechanized and is suitable for the connection between large platforms, and has a brighter application prospect. For the vast.

Description

technical field [0001] The invention relates to a platform connection device, in particular to a platform connection device for large-scale deep-sea fishing grounds. Background technique [0002] With the improvement of people's living standards in our country, people's demand for aquatic products continues to increase, especially for some deep-water fish. my country has a marine land area of ​​nearly 3 million square kilometers, which has not been fully utilized yet. Therefore, the development of offshore aquaculture, especially deep-sea aquaculture, the formation of marine pastures and blue granaries, and the provision of food production and quality assurance are the focus of aquaculture in the future. Fish farming is an important part of my country's marine economy, and large-scale marine fish farming is based on the reality of marine fishery resources. [0003] my country's deep-sea aquaculture technology is currently in the development stage and has a broad prospect. ...

AI Technical Summary

Problems solved by technology

At present, offshore aquaculture is relatively mature in domestic development. The wind and waves in the offshore area are relatively small, and the interaction between platforms is not large. Therefore, the existing connecting device only considers the connection between platforms. According to a certain method such as cross-winding connection, for deep-sea aquaculture areas, no effective connection device is provided to overcome the extrusion force between platforms

[0006] 2. The existing connection device does not analyze the maximum point of force for the specific position, the device is too single, and the use is unreasonable

However, existing connection devices have not yet addressed this issue.

[0007] 3. The existing connection device does not have a certain test basis to determine the maximum point of tension and compression

Existing connection devices do not analyze this situation based on physical model tests
