Leaking liquid driven system, transport device and leaking liquid driven method
By installing a room-temperature gas source in the fuel tank to connect the leak collection pipeline and the purging pipeline, the room-temperature gas is used to drive the rapid flow of cryogenic fuel and accelerate its vaporization, thus solving the problem of cryogenic damage caused by the liquid accumulation pan and achieving safe and reliable protection for the transport device.

AI Technical Summary
Technical Problem
In the prior art, the accumulator tray of the fuel tank causes low-temperature damage to the hull structure when collecting cryogenic fuel, affecting the structural strength and service life.
Method used
By setting up a normal temperature gas source connected to the leak collection pipeline and the purging pipeline, the normal temperature gas is used to drive the rapid flow of cryogenic fuel, and the vaporization is accelerated through heat exchange and the purging pipeline, thus preventing cryogenic damage.
Benefits of technology
It enables rapid vaporization of cryogenic fuels, protects the structural strength of the transportation equipment, improves operational safety, and reduces maintenance costs.

Abstract
This invention discloses a leaking liquid driving system, a transport device, and a leaking liquid driving method. The leaking liquid driving system is used on a transport device with a fuel tank. The system includes: a sump for collecting leaked cryogenic fuel from the fuel tank; a room-temperature gas source for supplying a room-temperature gaseous medium; a purge line located below the sump, with multiple purge ports facing the sump to spray the room-temperature gaseous medium to the bottom of the sump; a leak collection line, with its inlet connected to a leak channel space at the bottom of the fuel tank, at least a portion of which is located inside the sump for spraying cryogenic fuel; and the room-temperature gas source connected to the inlet of the leak collection line and the inlet of the purge line. The room-temperature gas drives the cryogenic fuel to flow rapidly, initially raising the liquid temperature. The purge line directly raises the temperature of the sump itself, promptly dissipating cold energy.
