Description

Technical Field

[0001] The utility model relates to a marine power device for generating electricity from methanol gas, belonging to the technical field of marine power devices. Background Art

[0002] Methanol is now widely used as fuel for ships due to its high efficiency and low pollution. Methanol is directly injected into the combustion chamber, mixed with air and ignited to generate high-temperature and high-pressure heat energy, which is then converted into electrical energy through turbine machinery, and then the electrical energy drives the ship's power unit to work.

[0003] A Chinese patent discloses a detachable marine power device with the publication number CN208248477U. The technical solution disclosed in the patent document is as follows: a power component, which is installed at the rear of the electrical compartment and is used for propulsion; an adjustment component, which includes a first adjustment part installed at the rear end of the electrical compartment and a second adjustment part installed at the front end of the electrical compartment, and the first adjustment part and the second adjustment part are both used to adjust the motion state of the main ship; and a drive component, which is installed inside the electrical compartment and is used to control the power component to work.

[0004] In order to solve the problem of secondary processing of the hull, which affects both the cost and the waterproof performance, the existing technology adopts the method of installing the battery pack and the control group in the electrical compartment. However, there is still a situation where the power motor cannot be protected from overload. If the propeller is entangled by foreign objects, the power motor will be subjected to a large load, which can easily cause the power motor to overheat and be damaged, causing great economic losses to users.
