Abstract

The invention discloses a lifting shore power junction box, which comprises a junction box body, a hydraulic lifting device and a shore power transmission cable, wherein a placement groove is dug under the ground; the hydraulic rod of the hydraulic lifting device is fixed on concrete on the bottom of the placement groove; the hydraulic lifting device is connected with a remote shore power supply control system; the remote shore power supply control system controls the hydraulic lifting device to rise or lower; the junction box body is stably placed on the hydraulic lifting device; the upper part of the junction box body is provided with a junction plugin; one end of the junction plugin is connected with a shore power supply through a shore power transmission cable, and other end of the junction plugin is used for connecting an external ship; the junction box body is square and is made of stainless steel materials, and the level of protection of the junction box body achieves IP (Ingress Protection)65; support beams are added in the junction box body and are cruciform, and a cruciform center point of the bottom is connected with the support rod of the hydraulic lifting device; the placement groove is dug from the front edge of a wharf and is deep enough to contain the hydraulic lifting device and the junction box body, and the inner wall of the placement groove is smooth and anti-corrosion.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a liftable shore power junction box. Background technique [0002] With the continuous and rapid development of the national economy, the pace of port construction is getting faster and faster, and the number and density of ships berthing at the docks have increased significantly. For this reason, a large amount of fuel oil has been consumed, forming a spectacular "sea floating chimney". During the berth of the ship, in order to meet its own electricity demand, the auxiliary generator consumes a large amount of heavy oil for power supply. [0003] Due to the limitations of the quality, scale, and quality of the ship's own equipment for power supply by fuel oil, the utilization rate of fuel oil is not high and the loss is serious, and the excess electric energy generated by the ship's diesel engine cannot be stored, which wastes a lot of energy and causes damage to the por...
