Connection device for large-scale fishery platforms at deep open sea

Abstract

The invention discloses a connection device for large-scale fishery platforms at the deep open sea. The device comprises three or more damping devices and two or more X-shaped anchor chain devices, and the damping devices and the X-shaped anchor chain devices are arranged between the two fishery platforms; each damping device comprises a spherical connection rod, two pistons arranged at the two ends of the spherical connection rod respectively, an air cylinder matched with the pistons and two connection fixing components. The two ends of each spherical connection rod can freely rotate in the corresponding pistons. Each X-shaped anchor chain device comprises two cross anchor chains, the two ends of each anchor chain are connected with fixing parts respectively, and the fixing parts are fixedly connected with the upper surfaces of the fishery platforms. The connection device for the large-scale fishery platforms at the deep open sea is optimized in structure, has an obvious effect and islong in service life, safe and efficient. Compared with a traditional connection device for fishery platforms, the connection device has the advantages of being capable of achieve mechanization trend, suitable for connection among the large-scale platforms and wider in application prospect.

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
