This invention discloses a system for coupling underground salt cavern energy storage and nuclear energy based on a dynamic heat pipe, belonging to the field of physical energy storage technology, and mainly used for coupling underground salt cavern energy storage and nuclear energy. The technical problem to be solved by this invention is to provide a system for coupling underground salt cavern energy storage and nuclear energy based on a dynamic heat pipe, including a salt cavern, a compressor, an expander, a nuclear power plant, and a dynamic heat pipe system. The compressor and expander are electrically connected to the nuclear power plant. The dynamic heat pipe system includes an interconnected evaporation section, a condensation section, and a storage tank. The evaporation section is connected to the nuclear power plant, and the condensation section is located between the salt cavern and the expander. A storage tank is located between the evaporation section and the condensation section, containing a heat exchange medium. A mechanical pump is located between the storage tank and the evaporation section. This invention utilizes a dynamic heat pipe system to achieve coupling between a nuclear energy system and an underground salt cavern energy storage system, fully utilizing the energy generated by the underground salt cavern and the nuclear power plant, and improving the energy utilization rate of the entire coupled system.

This utility model discloses a crayfish temporary holding device, solving the problem of large space requirements and inconvenient management in existing crayfish farming. The utility model includes several stackable temporary holding boxes, an installation mechanism inside each box, a detachable shielding mechanism on the installation mechanism, a detachable top cover on the box, a rotatable feeding mechanism for feeding and observing the crayfish, and a connecting mechanism on and connected to each box for connecting adjacent boxes. Ventilation holes are evenly distributed on the box and top cover, and the connecting mechanism has an inlet and an outlet. This utility model's temporary holding device consists of multiple independent boxes that can be stacked or used individually, thus reducing the installation space required for crayfish temporary holding. The shielding mechanism is detachably installed on the installation mechanism, providing a climbing and sheltering area for the crayfish.
