Liquid hydrogen transfer, mobile hydrogenation and transfer injection tank car

The invention relates to a liquid hydrogen transfer, mobile hydrogenation and transfer injection tank car which comprises a liquid hydrogen tank car, and an exhaust path, a self-pressurization loop, a liquid hydrogen filling path and a liquid hydrogen conveying path which are arranged on the liquid hydrogen tank car. Liquid hydrogen transfer, mobile liquid hydrogen filling and transfer filling between tank cars can be carried out, the fluctuating liquid hydrogen requirement of the liquid hydrogen refueling station can be met, the mobile liquid hydrogen refueling station can also be used as a mobile liquid hydrogen refueling station, and the requirements of various situations during liquid hydrogen transfer are met. And meanwhile, the liquid hydrogen transfer, mobile hydrogenation and transfer injection tank car can also recover the cold energy of evaporated cold hydrogen generated in the processes, so that the resource waste is reduced. 本发明涉及一种液氢转运、移动加氢与转注槽罐车,包括液氢槽罐车和均设置于所述液氢槽罐车的排气路、自增压回路、液氢加注路以及液氢输送路，所述液氢转运、
