Abstract

The invention provides a seabed node, the seabed node comprises a buoyancy device, a base device and a controller, the buoyancy device is installed at the top of the seabed node, and the buoyancy device comprises a water storage cavity; a communicating vessel, wherein one end of the communicating vessel is communicated with the water storage cavity; an electromagnetic valve which is communicated with the other end of the communicating vessel; a compression water pump which is communicated with the electromagnetic valve; a base device which is mounted at the bottom of the seabed node, comprises a waterproof electromagnetic device and is connected with the seabed node; a counterweight which is electromagnetically coupled with the waterproof electromagnetic device; and a controller which is used for controlling the electromagnetic valve to be opened and controlling the compression water pump to inject water into the water storage cavity through the communicating vessel, so that the seabed node sinks; the controller further controls the electromagnetic valve to be opened, controls the compression water pump to enable the water storage cavity to drain water through the communicating vessel, and controls the waterproof electromagnetic device to enable the configuration and the waterproof electromagnetic device to be decoupled, so that the seabed node floats upwards.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploration and development, and in particular, relates to a submarine node. Background technique [0002] In recent years, with the gradual advancement of offshore oil exploration and exploitation to the deep sea, the application demand for deploying submarine nodes to obtain information has gradually increased. At present, the deployment of submarine nodes in deep water areas uses underwater robots to deploy each submarine node to a designated location one by one under the guidance of the positioning system, and the recovery process is similar to this. [0003] The inventors of the present application found that the conventional operation method is inefficient because the number of subsea nodes carried by the underwater robot is limited each time, and it takes a long time to deploy and recover. In addition, due to the large size of underwater robots, it is difficult to correct the...
