This invention relates to an automatic protective device for tumor particle beam distribution equipment, comprising a working platform, an equipment base, a particle emission base, a protective cover, a guide bracket, a baffle plate, an air curtain structure, a micropore cleaning component, and an emergency triggering component. The protective cover is detachably connected to the equipment base via magnetic attraction. Connecting pipes on both sides of the cover cooperate with the spray nozzles to form an air curtain to block impurities. The baffle plate is constrained by a traction rope. When the equipment is misaligned, the traction rope breaks, and the baffle plate descends under gravity to block impurities. The tungsten sand fluid inside the rubber bladder is pressurized to achieve a seal. The emergency triggering component cooperates with a beam monitoring sensor to quickly cut off the connection in case of accidental emission. The baffle plate provides emergency blocking under the action of a compression spring. When the baffle plate descends, a scraper and a micropore cleaning component simultaneously clean the surface of the emission end and the precision micropores. This invention solves the problems of existing protective devices having a single beam blocking trigger, slow baffle plate response speed, and poor protective effect.
