Volute spring energy storage ocean temperature difference energy obtaining and conversion power generation device

Abstract

The invention discloses a volute spring energy storage ocean temperature difference energy obtaining and conversion power generation device which comprises a temperature difference energy obtaining unit, a mechanical transmission unit and a power generation unit. The temperature difference energy obtaining unit is composed of a heat exchange pipe, a press machine and a flowmeter; the mechanical transmission unit is composed of a one-way hydraulic cylinder, a lead screw and nut mechanism, a ratchet mechanism, a volute spring mechanism and a speed increase mechanism; and the power generation unit comprises a permanent magnet brushless direct current motor and a circuit control board, the heat exchange pipe is connected with the one-way hydraulic cylinder through a pressure gage and the flowmeter, a screw of the lead screw and nut mechanism is connected with a ratchet shaft of the ratchet mechanism, the ratchet shaft is connected with an input shaft of the volute spring mechanism, an output shaft of the volute spring mechanism is connected with a speed increase shaft of the speed increase mechanism, and an output shaft of the speed increase mechanism is connected with the permanent magnet brushless direct current motor. The device has the beneficial effects of avoiding disassembling, being long in service life, capable of being repeatedly used and free of pollution and the like.

Description

technical field [0001] The invention relates to a device capable of acquiring external temperature difference energy and converting it into electrical energy, in particular to a marine temperature difference energy acquisition and conversion power generation device with a coil spring energy storage. Background technique [0002] In the field of underwater submersible energy, use rechargeable batteries or disposable batteries to provide energy, fully charge the battery or install a fully charged disposable battery on the shore or on the mother ship, and wait until the submersible power is exhausted. Then salvage it out to sea, recharge or replace the battery. So as to maintain the normal operation of the submersible. [0003] This energy supply method has certain defects, which are mainly manifested in: first, the main working place of the underwater submersible is the ocean. The special environment of the ocean is not suitable for human long-term operation, and it is very i...

AI Technical Summary

Problems solved by technology

[0003] This energy supply method has certain defects, which are mainly manifested in: First, the main working place of underwater submersibles is the ocean, and the special environment of the ocean is not suitable for long-term human operations, and it is very inconvenient to search and salvage underwater submersibles

Secondly, it is very inconvenient to disassemble and replace disposable batteries. The underwater submersible requires a compact structure and good airtightness. Disassembling the underwater submersible may damage its structure. Even if a rechargeable battery is used, its life is limited and it needs to be replaced regularly

Finally, the production of batteries needs to consume materials, and the disposal of scrapped batteries also requires material resources and manpower
