Abstract

Official abstract text for this publication.

A foreign matter collecting device provided at a ship propulsion device that is configured to apply a propulsive force to a ship, the foreign matter collecting device includes an anti-ventilation plate extending in a horizontal direction and a collecting part provided in the anti-ventilation plate. A flow path extending from a water intake port to a water discharge port is provided in the anti-ventilation plate. A filter configured to collect fine-grained foreign matters from a water flow in the flow path is provided in the collecting part.

First claim

Opening claim text (preview).

What is claimed is: 1. A foreign matter collecting device provided at a ship propulsion device that is configured to apply a propulsive force to a ship, the foreign matter collecting device comprising: an anti-ventilation plate extending in a horizontal direction; and a collecting part provided in the anti-ventilation plate, wherein a flow path extending from a water intake port to a water discharge port is provided in the anti-ventilation plate, wherein a filter configured to collect fine-grained foreign matters from a water flow in the flow path is provided in the collecting part, and wherein the anti-ventilation plate is provided integrally with the ship propulsion device. 2. The foreign matter collecting device according to claim 1 , wherein the collecting part is provided in a rear portion of the anti-ventilation plate, and wherein the water intake port is provided at a front portion of the anti-ventilation plate, and the water discharge port coupled to the collecting part is provided at a rear portion of the anti-ventilation plate. 3. The foreign matter collecting device according to claim 1 , wherein the anti-ventilation plate has a flat plate shape. 4. The foreign matter collecting device according to claim 1 , wherein a backflow prevention structure is provided in the flow path of the anti-ventilation plate between the water intake port and the collecting part. 5. The foreign matter collecting device according to claim 1 , wherein the collecting part is of a cartridge type, and the filter is a filtration member having a multilayer structure with different fineness. 6. The foreign matter collecting device according to claim 1 , wherein a rectifying device is detachably provided in the anti-ventilation plate. 7. A foreign matter collecting device provided at a ship propulsion device that is configured to apply a propulsive force to a ship, the foreign matter collecting device comprising: an anti-ventilation plate extending in a horizontal direction; and a collecting part provided in the anti-ventilation plate, wherein a flow path extending from a water intake port to a water discharge port is provided in the anti-ventilation plate, wherein a filter configured to collect fine-grained foreign matters from a water flow in the flow path is provided in the collecting part, and wherein the anti-ventilation plate is detachably provided at the ship propulsion device. 8. The foreign matter collecting device according to claim 7 , wherein the collecting part is provided in a rear portion of the anti-ventilation plate, and wherein the water intake port is provided at a front portion of the anti-ventilation plate, and the water discharge port coupled to the collecting part is provided at a rear portion of the anti-ventilation plate. 9. The foreign matter collecting device according to claim 7 , wherein the anti-ventilation plate has a flat plate shape. 10. The foreign matter collecting device according to claim 7 , wherein a backflow prevention structure is provided in the flow path of the anti-ventilation plate between the water intake port and the collecting part. 11. The foreign matter collecting device according to claim 7 , wherein the collecting part is of a cartridge type, and the filter is a filtration member having a multilayer structure with different fineness. 12. The foreign matter collecting device according to claim 7 , wherein a rectifying device is detachably provided in the anti-ventilation plate.
