Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 and figure 2 As shown, bolt holes for fixing are distributed on the base 1 of the device, and bearing supports 2 are respectively provided at both ends. The coaxial large runners 5 and 6 on the left side of the device are discs with grooves on the radially outer edge. The disc center of the rotating shaft 3 is arranged, and is matched with the left support of the base through bearings, and the bearing cap 4 is arranged on the rotating shaft 3 top. The coaxial small runner 10,11 on the right side of the device is a disk with grooves on the radially outer edge, and the center of the rotating shaft 9 disks is arranged, and cooperates with the support on the right side of the base through a bearing. The large runner 5 and the small runner 11 in the front part of the device are connected and driven by a common transmission belt 8,...

Abstract

The invention discloses a power supply device of a submarine volcanic observation instrument based on the sea-water temperature difference. The power supply device mainly comprises two pairs of coaxial rotating wheels with different sizes, wherein one pair of coaxial rotating wheels is driven by an ordinary belt, and the other pair of coaxial rotating wheels is driven by an alloy belt made of two-way shape memory alloy. The power supply device is characterized in that the energy in a temperature field is converted into the rotational kinetic energy of an output shaft in the power supply device by utilizing the difference of the ambient temperatures of the upper part and the lower part of the shape memory alloy. Compared with the traditional overland long-distance power transmission mode, in the power supply device, the difficulty for realizing on the engineering is greatly reduced; and compared with power supply by a storage battery, in the power supply device, the energy in the temperature field near a submarine volcanic vent can be continuously converted into electric energy for a long time, and the technical difficulty for periodical replacement of the storage battery is reduced.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply device for submarine volcano observation instruments based on seawater temperature difference. Background technique [0002] Undersea volcanic activity produces undersea hydrothermal vents, and scientists have discovered unusual life forms and geological formations near these vents in recent years. Long-term monitoring of the marine environment near submarine volcanic vents is of great scientific significance for marine environmental monitoring, research on hydrothermal mineralization mechanisms and hydrothermal vent biomes. [0003] For long-term monitoring of the marine environment near submarine craters, submarine observation instruments need to perform long-term continuous operations on the seabed. Electric energy is very important in the submarine monitoring system. Without a continuous and stable power supply, all observation instruments cannot operate normally. [...
