The invention discloses an underwater robot temperature difference energy charging device, belonging to the technical field of underwater vehicles. The underwater robot temperature difference energy charging device comprises a robot body, the robot body is provided with a temperature difference energy generating device. The temperature difference energy generating device comprises: a transducing cavity sleeving the robot body in a ring shape; a temperature difference generating unit arranged at the outer wall of the transducing cavity; a seal cover forming a watertight holding cavity for holding the temperature difference generating unit with the outer wall of the transducing cavity; a heat pipe hinged at the bottom portion of the transducing cavity through a hinge seat and communicating with the transducing cavity; and a drive mechanism used to drive the heat pipe to rotate in the horizontal and vertical directions. In an AUV navigation state, the heat pipe is in the state of horizontal retraction, and in a charging state, the heat pipe is rotated to a vertical state, and is inserted into the heat liquid port. The hot end of the temperature difference generating unit arranged on the transducing cavity is subjected to temperature rise through heating, the cold end is in a low-temperature state close to the room-temperature seawater, and in the temperature difference effect, thetemperature difference generating unit outputs electric energy to charge the AUV to prolong the operation time of the AUV.
Description
technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to a temperature difference energy charging device for an underwater robot. Background technique [0002] There are rich biological communities, mineral resources, and geological structures near seafloor hydrothermal fluids that need to be observed and analyzed. AUVs are one option that can accomplish the above tasks. At present, the energy supply method of AUV is mainly battery-powered, and it needs to return to the voyage to charge after running for a period of time, and the hydrothermal vent is generally located 2,000 meters below the sea, and the deep sea is far away from the land, making it difficult to supply power to the observation equipment. [0003] One way of AUV power supply is to return to the mother ship after performing a mission for a period of time, that is, the single mission mode. After the AUV is recovered by the technician, it will be charged or re...
