Description

  The present invention relates to a configuration of a power generation device that supplies inboard power in a ship.

  A conventional marine vessel propulsion device includes an internal combustion engine, a power transmission device, and the like, and drives a propeller connected to the power transmission device after the driving force of the internal combustion engine is decelerated by the power driving device.

  The propulsion device supplies the output of the traveling internal combustion engine to the power generation device and the power transmission device, and supplies stable power to the power generation device and drives the propeller connected to the power transmission device. (For example, Patent Document 1).

  The conventional cooling configuration for power generation equipment is a configuration in which a cooling fan is provided on the flywheel, and ventilation equipment is formed in the flywheel housing and mounting flange to cool the power generation equipment, and the power generation equipment case is closed. As a result, the power generating device and the power generating device case, which are at the highest temperature, are difficult to be cooled, resulting in poor cooling efficiency. In addition, water generated by dew condensation or the like accumulates inside the case member, leading to corrosion of the generator section and life deterioration. When the cooling configuration is a water-cooling type, there is a problem that a system for the entire power generation device becomes complicated because pipes and pumps are attached, making maintenance work difficult and costly.

  Also known is a system in which an onboard power generation device is interposed between the internal combustion engine and a deceleration power transmission device, and the power generated by the power generation device is stably supplied to the ship via an inverter. (For example, Patent Document 2).

  In the conventional power generation equipment, the power output from the power generation equipment is converted into AC power by a single inverter and supplied with power, so it is necessary to use an inverter with a large output. However, when an inverter with a large output is used, there is a problem that costs are increased. Further, when the power generation device is interposed between the internal combustion engine and the power transmission device and covered with the case member, it is necessary to provide an extraction means for extracting the output from the inside of the case to the outside. Further, in the ship propulsion device, the power generation equipment is attached when the inboard power is required, and the power generation equipment is removed when it is not necessary. Therefore, if the mounting dimensions of the power take-out part of the internal combustion engine and the mounting dimensions of the power input part of the power transmission device are different depending on whether or not the generator is installed, the number of parts increases and costs increase. There was a problem that.

  Further, in the conventional propulsion device installation configuration, the internal combustion engine, the power generation device, and the power transmission device are integrally configured, and the propulsion device is mounted on the hull by supporting the internal combustion engine with a plurality of vibration isolation members. It was installed. However, in the conventional propulsion device, since the position of the attachment portion for attaching the vibration isolating member is limited, it cannot be easily attached to various types of ships.

  Therefore, in the present invention, in order to solve the above-mentioned problem, in the marine vessel propulsion device in which the internal combustion engine for traveling and the engine for power generation are made the same, a drainage structure that prevents corrosion and life deterioration of the generator section is provided. The present invention provides a power generation device and a cooling structure that are simple and inexpensive. In addition, we provide ship propulsion devices that can be easily installed in various types of ships, and in power generation equipment, it is possible to reduce costs while ensuring the total output capacity. It is also an object of the present invention to improve the performance and wiring workability.
