Ship shore-based automatic safe power supply method and device

Abstract

The invention relates to a ship shore-based automatic and safe power supply method and device. The method comprises the following steps: 1, output electric energy of a ship shore-based power supply center monitors a power quality parameter through a power monitor unit, and the electric quantity is measured by a power terminal measurement unit and led out to a complete power supply unit through a cable; 2, the water level is detected by adopting a water level monitor transmission unit and uploaded to a power supply control unit, and the power supply control unit controls the cable paying-off height in real time according to the data of the water level, so that the complete power supply unit is controlled to be always positioned on a water surface safety position; and 3, a power supplier and a power user record the current power quantity, a power supply start button is started, and power supply is started. According to the ship shore-based automatic and safe power supply method and device, the heights of an interface and a plug socket can be regulated in real time according to a water surface height signal, the electric connector is always guaranteed to be in a safe range, and the aim of safe power supply is realized.

Description

technical field [0001] The invention relates to a device and a method for using a power source on land to supply power to a ship docked on a shore base, in particular to a method and a device for automatically and safely supplying power to a ship's shore base. Background technique [0002] When the ship is docked at the dock, the diesel engine that provides power for the whole ship is in a low-load and variable-load operation state, and at this time it will discharge more harmful substances than normal operation. Generally, the concentration of NOx in the port cities along the Yangtze River is between 0.01 and 0.15 mg / m3, and the concentration of SOx is between 0.02 and 0.10 mg / m3, resulting in the air environment indicators in the central urban areas of these cities being close to or lower than the air quality stipulated by the state. The second-level standard, and some urban areas are even lower than the third-level standard. Among them, the estimated NOx and SOx emission...

Problems solved by technology

Although this patent realizes the frequency conversion of the power supply on land to supply power to ships in docked ports, the operation is troublesome. During the use, the power supply interface, plugs and sockets will be submerged by the rising water surface, and the risk factor is high, which affects the normal power supply.

[0004] Another publication number is CN102285318A, and the patent name is: a shore-based power supply device for river port ships. Although the device realizes the power supply of land power to ships in port, the operation needs to be operated on the panel of the shore power connection box. The installation position of the shore power connection box is easily affected by the structure layout of the wharf, which makes it impossible for the operator to monitor the operating position of the plug in real time

At the same time, since the water level on the coast of the port changes at any time, it is impossible to effectively adjust the height of the interface, plugs and sockets during use, which will easily cause the water level to rise rapidly and submerge the connectors and sockets, resulting in electrical safety issues

In addition, since the electricity can only be displayed on site, there is no electricity authentication method recognized by both parties, which may easily lead to disputes on electricity payment
