Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a methanol / diesel dual-fuel pusher. Background Art

[0002] Pushboats are motor boats used to push barges and barge fleets. Pushboats are developed from tugboats and need to be driven by methanol / diesel dual fuel when pushing boats for navigation.

[0003] For example, a methanol fuel dual-fuel ship with publication number CN113047994A includes a hull, a methanol fuel storage tank, a methanol fuel daily tank, a fuel preparation room, a methanol fuel supply system, a methanol valve unit, and a methanol fuel oil dual-fuel ship. Although the above document can realize the switching between the two supply modes of fuel oil and methanol fuel, making the ship a methanol and fuel oil dual-fuel supply, not only the investment cost and operating cost are low, but also the carbon emission and sulfur emission of the ship can be reduced; however, when in use, the dual-fuel pusher uses methanol / diesel to drive the motor during the voyage to make the propeller move. The dual-fuel pushboat rotates to drive the pushboat to move. When the propeller rotates, some floating branches or some water plants floating in the water may easily bump against the propeller or the water plants may be entangled around the propeller, causing damage to the propeller, thereby reducing the practicality of the dual-fuel pushboat. At the same time, when the dual-fuel pushboat is sailing, there is no protective structure on the outside of the dual-fuel pushboat to protect the hull of the dual-fuel pushboat and prevent the dual-fuel pushboat from hitting reefs in the water, resulting in a collision of the hull of the dual-fuel pushboat and damage to the hull, thereby reducing the protection effect of the dual-fuel pushboat.
