Marine DC Power Unit

Abstract

The invention discloses an ocean direct current power source device which is installed underwater. The ocean direct current power source device comprises a flow guiding cover in a both-way horn shape. An alternating current generating device is installed in the flow guiding cover and comprises an outer rotor. Blades are arranged on the outer surface of the rotor. A permanent magnet is arranged on the inner surface of the rotor. A stator is arranged in the rotor. A shaft penetrates the center of the stator. The rotor is rotationally installed at the two ends of the shaft through bearings, and the load is transmitted to the stator through the bearings at the two ends. The alternating current electric energy output end of the alternating current generating device is connected with a direct current electric energy module converting the alternating current electric energy into the direct current electric energy. The direct current electric energy module comprises a rectifier circuit. The input end of the rectifier circuit is directly connected with the alternating current electric energy output end of the alternating current generating device. The output end of the rectifier circuit is connected with a voltage stabilizing circuit. The output end of the voltage stabilizing circuit is the direct current electric energy output end of the direct current electric energy module and is connected with other direct current power utilization devices.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery and electronic equipment, and relates to a marine direct-current power supply device for generating electricity and outputting direct-current electric energy by bidirectionally utilizing ocean tidal current or river current energy. Background technique [0002] With the development of modern economy and military technology, the application requirements of underwater equipment, especially military underwater equipment, are becoming more and more extensive, including nearshore, offshore, far sea, deep water, and deep sea. However, although most of the equipment or equipment that needs to be used for a long time are electronic products, the power supply voltage is not high, and the power demand is not large, they all need long-term power supply or backup power. Therefore, the power supply is an extremely critical issue affecting its use effect. [0003] At present, most of the underwater equ...

Problems solved by technology

However, although most of the equipment or equipment that needs to be used for a long time are electronic products, the power supply voltage is not high, and the power demand is not large, they all need long-term power supply or backup power. Therefore, the power supply is an extremely critical issue affecting its use effect

[0003] At present, most of the underwater equipment used for a long time is powered by batteries, which have a short service life and need to be replaced regularly, making maintenance difficult and costly. Cabling and post-maintenance are also quite difficult

In addition, frequent maintenance is not suitable for military applications
