Shore-based wireless charging device for electric ship

Abstract

The invention discloses a shore-based wireless charging device for an electric ship. The device comprises a shell, a fixed ring is fixedly connected to the inner wall of the shell, an electric energyemission device is fixedly connected to the inner wall of the fixed ring, a motor is fixedly connected to the upper surface of the shell, the bottom of an output shaft on the motor is fixedly connected with a rotating shaft, the surface, close to the top, of the rotating shaft penetrates through the top of the shell and is rotatably connected with the shell, and fan blades are fixedly connected tothe bottom of the rotating shaft. Through cooperative use of the structures, the problems that in the actual use process, due to the fact that the shore electric energy emission device and an electric energy receiving device on the ship are in wireless attraction, and when electric transmission is carried out, a large amount of heat is generated, power transmission efficiency is easily reduced, meanwhile, the service life of the device is easily shortened, according to traditional wind cooling, air with water steam on the shore is easily blown to the device, the device is prone to failure, and inconvenience is brought to use are solved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a shore-based wireless charging device for electric boats. Background technique [0002] In the prior art, ship shore power technology is a kind of power supply technology used when ships are docked. At present, large ships, especially oil tankers and container ships, usually use fuel oil products (mostly heavy oil and diesel) to generate electricity when they are in port to meet the electricity demand of ships. Fuel products such as heavy oil and diesel produce a large amount of sulfide and nitrogen oxides during the combustion process, causing serious pollution to the surrounding environment. After pollution, the pollution can be spread to areas hundreds of kilometers away through climate effects. Moreover, many port areas at home and abroad are concentrated in urban areas, and the contradiction between pollution caused by ships calling at ports and environmen...

Problems solved by technology

The existing dockside power supply technology for berthing ships is an important means to reduce pollutant emissions during berthing; however, the traditional shoreside power supply devices for port docks are all wired transmission, and the connection process is more cumbersome than wireless charging. And when connecting, there is also a certain risk. For this reason, people propose a shore-based wireless charging device for electric boats, such as a wharf power supply device based on wireless charging technology disclosed in Chinese patent CN208094272U, including power supply device and a power receiving device; the power supply device includes a solar panel, a supercapacitor, an electric energy transmitting device, a camera and the first infrared sensor; the solar panel, the supercapacitor and the electric energy transmitting device are electrically connected in turn; the first infrared sensor and the camera are arranged on On the top surface of the power transmitting device; the power receiving device includes a second infrared sensor and a power receiving device, and the second infrared sensor is arranged on the top surface of the power receiving device; The basic power supply mode reduces the cumbersome process and potential danger of manual wire insertion; the use of solar power supply does not need to be connected to the municipal power grid, which is safe, environmentally friendly, and pollution-free; in addition, the structural configuration of its power supply device and power receiving device is reasonable to ensure its application and popularization. However, in actual use, a large amount of heat will be generated when the power transmitting device on the shore and the power receiving device on the ship perform wireless absorption and power transmission, which will easily reduce the power transmission efficiency and make the equipment The service life is reduced, and the traditional wind cooling is easy to blow the air with water vapor on the shore into the equipment, and it is also easy to cause the equipment to break down and bring inconvenience to the use
