Problems solved by technology

[0003] During the use of the existing offshore oilfield shore power connection device, if the sea level rises or other natural factors are encountered, the connection between the cable and the distribution box will be eroded by sea water, which will seriously affect its service life. However, the existing shore The electrical connection device has not been considered in this regard, resulting in the need for irregular replacement of the shore power connection device, which increases the cost input

Abstract

The invention belongs to the technical field of shore power connection, and particularly relates to an offshore oilfield shore power connection device based on shore-based power supply, which comprises a power distribution box, supporting plates are fixedly connected to the outer walls of the two sides, close to the top end, of the power distribution box, and air cylinders are fixedly connected to the outer walls of the tops of the two supporting plates. The outer walls of the tops of the two air cylinders are fixedly connected with connecting plates. According to the invention, by arranging the air cylinders, the wire plate, the connecting cylinders and the telescopic pipe, when a cable for shore power connection is installed, the cable is guided through the wire plate, and when the sea level rises or during influence of other natural factors, the air cylinders can be adjusted to drive the wire plate to rise, so that the telescopic pipe is driven to stretch; the cable connecting height is increased, corrosion caused by seawater to the cable is avoided, meanwhile, the telescopic pipe can also shield the shore power connection place, external seawater is prevented from entering the distribution box, and the interior of the distribution box is kept dry.

Description

technical field [0001] The invention relates to the technical field of shore power connection, in particular to a shore power connection device for offshore oil fields based on shore-based power supply. Background technique [0002] my country's offshore oil is now mainly being explored and developed by China National Offshore Oil Corporation, currently operating in the Bohai Sea, the South China Sea and the East China Sea, and has built a large number of offshore cooperative and self-operated oil and gas fields. In 1999, the output of crude oil was 16.16 million tons and natural gas was 440,000 cubic meters. The company has good economic benefits. In the construction of offshore oil fields, it is necessary to connect power supply through shore power connection devices. [0003] During the use of the existing offshore oilfield shore power connection device, if the sea level rises or other natural factors are encountered, the connection between the cable and the distribution ...
