The invention discloses a vacuum suction cup isolation type automatic anti-ice device and method of a low-temperature filling system. The device comprises a suction cup (3). A tray (5) and elastic supporting plates (4) are fixed to the suction cup (3). A sliding shaft (15) is fixedly arranged on the tray and is mounted in a base (10) in a sleeved manner. A proximity switch (14) and an induction block (9) are fixedly arranged on the base and the sliding shaft correspondingly. An air suction hole connector (7), an air inlet hole connector (8) and a pressure sensor (6) are arranged on the tray. The method comprises the following steps that the device is aligned to and approaches to the low-temperature filling system, after the device is in contact with the low-temperature filling system, a spring is compressed, and the device stops propulsion; negative pressure is formed in the suction cup; and the device is adsorbed to the low-temperature filling system, and the anti-ice function is achieved. The vacuum suction cup isolation type automatic anti-ice device and method of the low-temperature filling system have the beneficial effects of being good in anti-ice good, high in adaptability, high in universality, high in automation degree, safe to use and the like.
Description
technical field [0001] The invention relates to the field of automatic low-temperature filling, in particular to a vacuum suction cup isolated automatic anti-icing device and method for a low-temperature filling system. Background technique [0002] In aerospace, aviation, LNG and other fields, cryogenic filling systems are widely used to fill cryogenic media (liquid hydrogen, liquid oxygen, liquid natural gas, etc.) During the low-temperature filling process, the temperature of the filling device, connectors, valves and other equipment in the filling system drops rapidly under the action of the low-temperature medium, and due to the moisture in the outside air, frost and ice appear on the outer wall. Especially after the low-temperature filling is completed and the equipment falls off, the inner cavity of the equipment is exposed to the air, and frosting and freezing occur rapidly. In order to ensure the safety of the low-temperature filling system and the normal execution...
