An offshore planting platform utilizing wave energy and temperature difference energy and its working method

Abstract

The invention discloses a seaborne planting platform using wave energy and temperature difference energy and a working method thereof. The seaborne planting platform comprises a floating platform, a turbine power generation component, a sea water desalinating and circulating system and an anchoring system, wherein the floating platform sequentially comprises an indicator lamp layer, a plant growth layer, a soil layer, an equipment layer and an air chamber layer from top to bottom; vent holes are formed in the outer wall of the plant growth layer and communicated with the atmosphere, and raw materials needed by photosynthesis are provided for plants; a steam channel with permeable holes is pre-buried in the soil layer and used for irrigating crops planted in the soil; facilities such as water pumps, a heater and a control module are fixed in the equipment layer. When waves are incident into the air chamber layer, a turbine is impacted by airflow generated by wave fluctuation to convert energy of an oscillating water column into mechanical energy of the turbine, and then a power generator is driven to generate power. The invention provides a sea water desalinating method, which is low in cost, convenient and fast, of the seaborne planting platform.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to an offshore planting platform utilizing wave energy and temperature difference energy. Background technique [0002] With the aggravation of the global energy crisis, the greenhouse effect and the environmental pollution caused by the exploitation of traditional energy sources, the development of marine renewable energy has attracted more and more attention. Among them, wave energy has attracted widespread attention due to its huge reserves. At present, a large number of wave energy devices in various forms have been developed. type, raft type, point absorption type, magnetic fluid wave energy generation device. Among them, the development technology of floating oscillating water column wave energy generation device is widely used. Under the action of wave incident waves, the water column in the air chamber is excited to oscillate, pushing th...
