Description

Technical Field

[0001] This invention relates to a convenient cable protection pipe for shore power supply on ships. Background Technology

[0002] Currently, with the rapid development of the global economy and the increasing attention paid to the human living environment, especially the atmospheric environment, by countries around the world, ships, as one of the sources of air pollution emissions, are increasingly required by national cities to use shore power after docking. In addition, the International Maritime Organization's sulfur limit order requires that the sulfur content of fuel oil for ships when docking be ≤0.1%. Shore power is being promoted as a zero-emission solution. Therefore, how to quickly, conveniently and safely connect to shore power is particularly important. The emergence of convenient cable protection pipes has perfectly solved this problem. Summary of the Invention

[0003] The purpose of this invention is to provide a fast, convenient, and safe portable cable protection pipe for ship shore power.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: a convenient cable protection pipe for shore power on ships, comprising a steel pipe (1), a sealing cap (2), a chain (4), a first eye plate (5), a second eye plate (6), a wing nut (8), a pin (9), and a clamp (10). The main body of the steel pipe (1) is fixed to the hull, the sealing cap (2) is installed at the end of the steel pipe (1), the first eye plate (5) is fixed to the upper part of the steel pipe (1), and one end of the chain (4) is fixed... The first eye plate (5) is fixed inside the second eye plate (5), and the other end is fixed on the sealing cover (2), thereby enabling the sealing cover (2) to open and close with the first eye plate (5) as the center. The second eye plate (6) is fixed to the lower part of the steel pipe (1). One end of the pin (9) is connected inside the second eye plate (6), and the other end is fixed to the outside of the sealing cover (2) by the butterfly nut (8) and the clamp (10). The clamp (10) is fixed at the lower end of the sealing cover (2) and is on the same straight line as the chain (4).

[0005] A rubber sheet (3) is provided between the sealing cap (2) and the steel pipe (1) to provide a sealing effect.

[0006] One end of the chain (4) is fixed inside the first eye plate (5) by the first bolt (10).

[0007] One end of the pin (9) is connected to the second eye plate (6) by the second bolt (7), so that the pin (9) can rotate freely.

[0008] This invention relates to a convenient cable protection pipe for shore power systems on ships. It has a simple design, uses mostly pre-made parts, saving an average of 40% in material usage. It is fixed with wing bolts, making operation quick and convenient, saving an average of 50% in labor, greatly improving operational safety, providing convenience for later maintenance and replacement, ensuring its watertightness, and preventing seawater from entering.

[0011] like Figure 1 and Figure 2 As shown, the ship shore power convenient cable protection conduit includes a steel pipe 1, a sealing cap 2, a rubber sheet 3, a chain 4, a first eye plate 5, a second eye plate 6, a wing nut 8, a pin 9, and a clamp 10. The main body of the steel pipe 1 is fixed to the hull. The sealing cap 2 is installed at the end of the steel pipe 1. The rubber sheet 3 is placed between the sealing cap 2 and the steel pipe 1 to provide a seal. The first eye plate 5 is fixed to the upper part of the steel pipe 1. One end of the chain 4 is fixed inside the first eye plate 5 by a first bolt 10, and the other end is fixed to the sealing cap 2, thereby enabling the sealing cap 2 to open and close with the first eye plate 5 as the center. The second eye plate 6 is fixed to the lower part of the steel pipe 1. One end of the pin 9 is connected inside the second eye plate 6 by a second bolt 7, allowing the pin 9 to rotate freely. The other end is connected to... The wing nut 8 and clamp 10 fix the pin 9 to the outside of the sealing cover 2, ultimately achieving the watertight requirement of the ship's shore power - convenient cable protection pipe during navigation. The clamp 10 is fixed at the lower end of the sealing cover 2 and is in the same straight line as the chain 4. When the ship docks, simply rotate the wing nut 8 outward a few threads to make the pin 9 rotate and fall around the second bolt 7, quickly opening the sealing cover 2 and realizing the rapid opening of the ship's shore power cable protection pipe. Finally, the shore power cable can be conveniently and quickly sent into the shore power equipment room. The ship's shore power convenient cable protection pipe of this invention has operational safety and convenience, and can perfectly solve the actual need for the ship to connect to shore power as soon as possible after docking, improving the timeliness of the crew during the use of the ship.
