Telescoping bank foundation LNG filling arm

Abstract

The invention discloses a telescoping bank foundation LNG filling arm which comprises a traction device, a rail, rollers and an LNG filling arm body. The LNG filling arm body comprises an LNG liquid-phase arm and an LNG gas-phase arm, and the LNG liquid-phase arm and the LNG gas-phase arm are both telescoping filling pipes. The rail is arranged along a bank slope of a bank foundation, and the rollers are arranged in the rail. The LNG liquid-phase arm and the LNG gas-phase arm are both connected with the rollers. The LNG liquid-phase arm and the LNG gas-phase arm are pulled by the traction device through a steel wire rope to move back and forth along the rail, and finally expansion and contraction of the LNG filling arm body are completed. According to the telescoping bank foundation LNG filling arm, fluid loading and unloading work can be carried out on a ship located at any water level, the security coefficient is high, leakage is not prone to happening, and cold energy losses are low.

Description

technical field [0001] The invention relates to a fluid loading and unloading device, in particular to a retractable shore-based LNG filling arm. Background technique [0002] With the popularization of the concept of environmental protection, LNG (low temperature natural gas) has been widely used as a clean energy. In order to protect the environment, my country has begun to try to change the ships powered by diesel and gasoline to use LNG as fuel power for ships operating in inland rivers and lake tourist areas. Due to the ultra-low temperature characteristics of LNG, the following problems will be caused when filling LNG ships on the shore, especially in the case of a large drop between the shore base and the water level, the use of conventional hose connections for filling will cause a large loss of cold energy , or leakage caused by wear and tear during the filling process, there are serious safety hazards; in addition, the conventional fixed filling arm is difficult t...
