REGENERATED ENERGY ELECTRICITY GENERATION DEVICE

Title:

REGENERATED ENERGY ELECTRICITY GENERATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/137370

Kind Code:

A1

Abstract:

The objective is to provide a regenerated energy electricity generation device equipped with a cooling mechanism capable of efficiently cooling the operating oil for a hydraulic transmission. A regenerated energy electricity generation device (1) is equipped with: a tower (2); a nacelle (4) rotatably supported at the apex part (2B) of the tower; a main shaft (14) that rotates together with rotary blades (6B); a hydraulic pump (8) driven by the rotation of the main shaft (14); a hydraulic motor (10) driven by operating oil supplied from the hydraulic pump (8); an electricity generator (12) linked to the hydraulic motor (10); an operating oil line (30) provided between the hydraulic pump (8) and the hydraulic motor (10), and in which operating oil flows; a cooling medium line (40) in which a cooling medium that cools the operating oil through an intermediate heat exchanger (52) circulates; and a main heat exchanger (51) that cools the cooling medium by exchanging heat with a cold water source comprising seawater, lake water, river water, or underground water in the vicinity of the base part of the tower. Either the operating oil line (30) or the cooling medium line (40) has first pipes (31, 34) supported on the nacelle (4) side, second pipes (32, 33) supported on the tower (2) side, and a connecting part (100) that connects the first pipes (31, 34) and the second pipes (32, 33) so as to be capable of rotation relative to one another.
