AI Technical Summary
Existing technologies make it difficult to safely and effectively conduct vibration detection on hydrogen-fueled ships. In particular, the technical means that cannot meet the requirements of ammonia and chlorine are: the flammability and explosiveness of hydrogen, its low density, and the installation requirements and high-pressure storage requirements increase the difficulty and cost of detection.
A vibration test sensor mounting fixture for hydrogen fuel cell ships was designed, including an acrylic base and studs, which are combined with vibration sensors and output wires and fixed to the hull with glue for testing.
The technical means for detecting ammonia chlorine can improve the safety and reliability of detection, and provide safety and cost-effectiveness.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of vibration detection special for hydrogen fuel ship, especially relates to a vibration test sensor fixing tool special for hydrogen fuel ship. BACKGROUND
[0002] Three gorges hydrogen boat 1 is a double -hull traffic ship with hydrogen fuel as the main and lithium iron phosphate battery power, is 500kw level hydrogen fuel cell power ship, and hydrogen fuel cell is the power source of the ship, is the core component of the ship, in order to facilitate better detection of the vibration of the ship in actual operation, a vibration detection tool and a feasible scheme are urgently needed, it is known that hydrogen is a highly flammable, explosive gas, therefore, in the vibration detection process, the detection tool has very high requirements, ordinary clamping tool on the market is difficult to meet the requirements, first, hydrogen needs to be stored in low temperature or high pressure environment to prevent its leakage or cause fire, second, due to the extremely low density of hydrogen, large storage tanks are needed to store sufficient amount, which also increases the installation difficulty of the tool, finally, due to the explosive property of hydrogen, strict safety measures are needed to ensure the safety during the detection process, these factors jointly cause the difficulty and cost of the vibration test of hydrogen fuel ship, in order to ensure the safety of ship navigation, facilitate better detection of the vibration of the ship in actual operation, improve the service life of hydrogen fuel cell, a vibration test sensor fixing tool special for hydrogen fuel ship is designed for the above problems. SUMMARY
[0003] The utility model discloses a vibration test sensor fixing tool special for hydrogen fuel ship can reduce the risk in vibration detection process, provide security level, have simple structure, convenient operation, save the cost characteristics, can fully satisfy the requirement of hydrogen fuel ship vibration test.
