Abstract: Disclosed is an anti-leakage device for a hydrogen storage container. 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.

Abstract: The present invention discloses a neuromorphic computer supporting billions of neurons, comprising hierarchical extended architecture and algorithmic process control within the architecture; the architecture comprises multiple neuromorphic computing chips with hierarchical organization management for implementing computing tasks, each containing computing neurons and synaptic resources and forming a neural network, spike events between computing neurons within the architecture are transmitted through a hierarchical transmission mode; the algorithmic process control comprises controlling parallel processing of computing tasks within the architecture, controlling management of synchronization time within the architecture, and controlling reconstruction of neural networks within the architecture to achieve fault tolerance and robust management of computing neurons and synaptic resources. The neuromorphic computer can support spiking neural network inference calculations with a neuron scale of billions.
