Problems solved by technology

Seabed-based instruments require a huge operating cost each time they are put in and updating the power supply device, ranging from tens of thousands of yuan to more than a hundred thousand yuan; in the process of recycling and re-launching, the risk of accidental damage is also increased due to weather. Possibility and difficulty of delivery. The use of submarine power supply cables for power transmission is only suitable for offshore areas where the power grid is more developed, and is particularly vulnerable to damage due to shallow waterways and harsh environments; obtaining power from the sea will also face wind and wave damage, line loss, and low reliability. , Difficult to hide and other unsolvable problems

Abstract

The electricity generating apparatus is composed of the dynamo shell the motor and stator, the stator and the coil of the disk generator is on the bottom of the taper shell, which installed on the thick disk chassis connect with taper chassis, the rotor is fixed on the taper shell, the rotor shaft connect with the annularity floatage rotor through flexible shaft, the generator rotor is permanent magnet with unguiform magnetic pole, the sand preventing rotor shaft is at the top of the taper shell, the foam floatage obturator hub rotate hob is on the middle of the annularity floatage rotor, with many blades and dentate cut to protect from dragnet destruction.

Description

technical field [0001] The invention belongs to the technical field of generators, and specifically relates to a generator that uses a conical base to adjust its position on the seabed and uses ocean currents to generate electricity. The international patent classification number is F03B 13 / 00. Background technique [0002] At present, marine development is a very promising career. With the full development of marine monitoring work, the monitoring work based on underwater seabed-based platforms in the marine three-dimensional real-time detection system has attracted more and more attention. This is because the seabed-based instrument system has the characteristics of long-term and all-weather continuous data acquisition, which is incomparable to any other current ocean monitoring methods, especially in the seabed engineering, related pollution deposition process and migration involved in the further development and utilization of the ocean. The law of ocean currents, the co...
