Semi-submersible type ocean current energy power generating system driven by blades

Abstract

The invention discloses a semi-submersible type ocean current energy power generating system driven by blades. The system comprises a floating body, a water assembly and an underwater assembly. The floating body is fixed to the seabed through a chain anchor, the water assembly is arranged on the upper portion of the floating body, and the water assembly comprises a universal joint and an alternating current power generator in transmission connection with the universal joint. The underwater assembly is arranged on the lower portion of the floating body, the underwater assembly comprises multiple groups of blade drive devices connected in series stage by stage and an active buoyancy control ball. The first group of blade drive device is in transmission connection with the universal joint, and the last group of blade drive device is connected with the active buoyancy control ball. The blade drive devices comprise connectors, segmented shafts and the blades sleeving the segmented shafts. The surface of the buoyancy control ball is fixedly connected with multiple ocean current rudders evenly, and a heavy object is further hung on the buoyancy control ball. According to the semi-submersible type ocean current energy power generating system driven by the blades, the number of the parts below the sea surface is further reduced, the sea water corrosion risk is reduced, the operating cost is reduced, and the installation limitation of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of ocean current power generation, in particular to a blade-driven semi-submersible ocean current power generation system. Background technique [0002] In today's energy situation, the development of new energy generation methods has become a hot research topic. The vast ocean, which accounts for 70% of the earth's surface area, concentrates 97% of the water and contains a large amount of energy, including wave energy, tidal energy, ocean current energy, temperature difference energy and salinity difference energy. As a new energy power generation method, ocean current energy has the characteristics of energy stability. Therefore, since the last century, many forms of power generation based on ocean current energy have emerged, among which the most widely used are the submarine blade type ocean current energy generation method and the vertical semi Submersible ocean current power generation method.

Problems solved by technology

All the transmission mechanisms and power generation equipment of this power generation method are under the water surface, so the waterproof requirements of the equipment are extremely high, and the construction is difficult; and due to the strong corrosion of seawater, the maintenance cost is relatively high

[0003] The traditional vertical semi-submersible ocean current power generation system is an improved system, which places the power generation equipment above the water surface, which alleviates the construction investment, maintenance difficulty and cost to a certain extent, but the driving blades under the water surface cannot be tilted in this way. That is to say, the distance below the water surface of this system cannot be changed, which brings difficulties to the maintenance and installation of the system

In view of the current situation of ocean current power generation, this paper proposes a new type of ocean current energy semi-submersible power generation system, which solves the problem of limited installation of traditional ocean current power generation systems and reduces maintenance costs
