Electric ship charging quick connection device

Abstract

The invention discloses an electric ship charging quick connection device, which comprises a plug and a socket, the plug is cylindrical, the front end of the plug is in a circular truncated cone shape, and the front end of the plug can be inserted into the socket; a positive electrode contact a and a negative electrode contact a are arranged on the outer surface of the plug; an electromagnet, an electromagnetic switch and a spring are arranged in the plug, the positive electrode contact a is connected with the anode of the electromagnet, the cathode of the electromagnet is connected with the electromagnetic switch, the electromagnetic switch is provided with the spring, and the spring is connected with a pull ring; the socket is provided with an insertion port, soft iron is arranged in the insertion port, and a positive electrode contact b and a negative electrode contact b are arranged on the inner wall of the insertion port; according to the invention, the plug and the socket are quickly connected in a magnetic manner and are not easy to fall off due to external force, and an effective, safe and stable connection state is realized.

Description

technical field [0001] The invention relates to a charging device for an electric boat, in particular to a fast connection device for charging an electric boat. Background technique [0002] Ships refer to those who use the buoyancy of water, rely on manpower, sails, engines (such as steam engines, gas turbines, diesel engines, nuclear power units) and other power to pull, pull, push, row, or push propellers and high-pressure nozzles to make A vehicle capable of moving on water. At present, most of the common ones rely on fuel oil to provide power to drive the operation of ships. Fuel combustion has significant defects: more waste gas and waste water are discharged, and the environmental pollution is relatively serious; noise pollution is very serious, and the comfort of the riding environment is relatively low; energy consumption The consumption is large, and the operating economy is poor. Especially in recent years, due to the rapid rise of fuel prices, ship operators are...

Problems solved by technology

At present, most of the common ones rely on fuel oil to provide power to drive the operation of ships. Fuel combustion has significant defects: more waste gas and waste water are discharged, and the environmental pollution is relatively serious; noise pollution is very serious, and the comfort of the riding environment is relatively low; energy consumption Large consumption and poor operating economy, especially in recent years, due to the rapid rise of fuel prices, ship operators are under greater pressure on operating costs

In the face of more stringent emission requirements, as well as improving the economic benefits of ship operations and meeting the special requirements of ships, people seek to solve the above problems by changing the energy source and propulsion mode of ships, and electric propulsion is an effective way. Now our company develops and produces electric boats, and the most important part of electric boats is the charging problem. The common charging mode in our life is plug-in connection, that is, the interface must be correctly aligned so that the power terminal and the charging terminal form an effective connection. To achieve power transmission, the traditional method for our company’s electric boats has caused a lot of inconvenience. For example, due to the impact of the shore environment, it is difficult for the staff to have the patience to slowly connect with plugs and sockets, and the shore environment Complicated, simple insertion of plugs and sockets, easy to fall off under external force, etc., these problems will appear, so there is an urgent need for a connection method that can quickly and accurately connect the power terminal and charging terminal to achieve safe and stable charging of electric boats
