Product Description
I. Buoy Body
1. Buoy body diameter 500mm, buoy wall thickness 8mm; It is in the shape of streamline ball, all made of ABS raw material. The floating body has high rigidity and high strength, which can meet the force requirement of the buoy when it is abandoned, and the structure is reliable. The two hemispheres of the buoy are sealed with O-rings and structural glue, so there is no risk of leakage. The upper hemisphere of the buoy is a transparent process to seal the solar power panel in the float ball and ensure that sunlight can normally beam into the solar power panel.
2. The solar power panel in the floating body is 20W, and the charging time of normal light for 1 hour can complete the charging of the lithium battery pack in the buoy. The entire power supply system provides more than 220 hours of continuous rainy days.
3. The lower hemisphere of the buoy is a comprehensive warehouse for sensors, circuits, acquisition boards and batteries. The lower hemisphere houses solar panels and communication modules.
4. The buoy can withstand strong typhoons with wind speeds above 60 m/s after strength calculation, and has a 15-year service life design.

The system can active and passive data reissue. When the buoy storage module has data reissue detected in the process of system transmission, the reissue program will be automatically started after the completion of the master transmission, and the system data will be reissue operation. Customers can also perform the manual data retransmission function through the remote server, sending the specified command, requiring the buoy communication system to send the specified data to the server.
Company Profile
Yantai Kekan Ocean Technology Co., Ltd. is a technology-based small and medium-sized enterprise that integrates the researchand production of marine observation and monitoring equipment, marine environmental services,and the development of key supporting systems for marine engineering. Adhering to the spirit of "scientfic management and exploration of the deep sea", it focuses on the research and development of intelligent marine observation and monitoring equipment and the safety guarantee of offshore engineering.
The R&D team of the company is led by Professor You Zajin, an academician of the European Academy of Sciences. He has been engaged in research on ocean dynamics, numerical model construction,and has led projects funded by the Natonal Young Scholars Fund, the Ministry of Sclence and Technology's key R&D project, the National Key Fund, and multiple Australian Key Fund projects.The core personnel of the team also include multiple doctoral and high-end managemert talents in the marine field, with complementary professional backgrounds and a solid foundation for cooperation. They have jointy cariedout muliple related projects/research projects and possess the strength of product design, manufacturing, and sales. Since its establishment, the company has applied for more than 30 patents and softworks, of which 13 have been authorized, possessing exclusive intellectual property rights and strong technical barriers.
The company's main products are intelligent marine environmental element observation and monitoring equipment and high-precision early warning and forecasting system, among which the intelligent observation and monitoring equipment has the function of self-positioning, which can adjust the positioning based on real-time sea conditions and relying on low-power power system; The submarine winch has the advantages of small size, strong traction and good sealing, which can better adapt to the complexity of the seabed work; The high-precision marine hydrological element early warning and prediction system provides wave, tide, storm surge and sediment transport data, solves the problems of unclear physical mechanism and low simulation accuracy of current numerical simulaton, and can provide a solid guarantee for marine enginering.
