A sealing assembly is connected to a right side of a tank body of an anti-leakage device, an impurity removing assembly is connected to a lower side of the tank body, and the impurity removing assembly is connected to the sealing assembly. By adopting the technical solution above, if the leakage occurs from the hydrogen storage container, hydrogen leaks into an inner cavity of the tank body, and an anti-leakage effect is achieved by intercepting and collecting the hydrogen. With the increase of the amount of hydrogen collected in the inner cavity of the tank body, an air pressure in the tank body increases, and a high-pressure gas pushes a first linkage block and a sealing sleeve to move to the right, making the contact between the sealing sleeve and a first cylinder closer.
