Abstract

The invention discloses an emergency data protection system for marine surveying equipment. The system is installed on a submersible. The system comprises an ejector and a data cartridge arranged in the ejector, the ejector comprises a shaft cavity and a cartridge cavity sequentially arranged along the axis of the ejector, and an opening formed in the outer side of the cartridge cavity is blockedby a sealing valve; the shaft cavity is provided with a first spring and a supporting and pushing shaft abutted against the first spring, a data cartridge with a truncated cone-shaped structure is arranged in the cartridge cavity, and two ends of the data cartridge are connected with a first elastic float ball and a second elastic float ball through cables respectively; in a sealing state, components which are abutted are sequentially the first spring, the supporting and pushing shaft, the second elastic float ball, the data cartridge, the first elastic float ball and the sealing valve, at themoment the first spring is in a compression state, and the first and second elastic float balls are in a flattening state.

Description

technical field [0001] The invention relates to an emergency data preservation device, in particular to an emergency data preservation system for marine survey equipment. Background technique [0002] Marine surveys often involve underwater data sampling and data measurement. Submersibles are frequently used equipment for underwater ocean surveys. However, due to the existence of uncertain factors such as mechanical failures and underwater obstacles, the submersible is stuck underwater, and the precious survey data may be more important than the submersible itself. Therefore, the data preservation work of the submersible needs to be done well. The data security system similar to the black box on the aircraft is the direction for reference of the technology of the present invention. The present invention needs to solve the problem of data preservation in case of various failures, accidents, etc. of marine survey equipment such as submersibles. Contents of the invention ...
