Technical Field
[0001] The utility model relates to a sea well, in particular to a top cover for the sea well. Background Art
[0002] As an indispensable and important equipment in the field of marine scientific exploration, the sea well is installed at the bottom of the cabin and goes deep into the sea to obtain various data in the sea, collect various types of resources or observe the specific conditions in the sea. It is generally installed on scientific research ships and is used to obtain comprehensive data of scientific research ships.
[0003] However, despite the importance of sea wells, the current equipment still has certain shortcomings. Since sea wells need to measure various data frequently, during maintenance, in order to facilitate observation of the internal structure of the cylinder, the top cover cannot be completely sealed. Although this design facilitates observation, it brings new problems during use.
[0004] When using a sea well, it is important to ensure that it is sealed to prevent seawater from seeping in. However, existing sea well equipment cannot meet this requirement, which restricts its function to a certain extent. Therefore, it is particularly important to improve the sea well. We need to optimize the structure of the sea well so that it can be completely sealed while maintaining excellent observation results. This not only helps prevent seawater from seeping in and ensures data accuracy, but also facilitates technicians to maintain the equipment and extend its service life. Summary of the invention
