Offshore floating type rainwater collecting and storing device

Abstract

The invention provides an offshore floating type rainwater collecting and storing device. The device comprises a spherical storage tank, wherein a water inlet is formed in the top of the spherical storage tank, and multiple rainwater collecting blades extending upwards are hinged to the inner wall in the circumferential direction of the water inlet; a floating pipe is fixedly arranged in the middle of the periphery of the spherical storage tank in the circumferential direction, and an external unit is arranged on the upper portion of the periphery of the annular storage tank; the interior of the annular storage tank is divided into a flow abandoning chamber, a water storage chamber and a collecting chamber communicated with the water inlet, wherein the flow abandoning chamber, the water storage chamber and the collecting chamber are sequentially arranged from bottom to top; the bottom of the water storage chamber communicates with the flow abandoning chamber in an adjusting mode, multiple turbulent flow units are arranged on the annular inner wall of the lower portion of the water storage chamber, and a filtering unit is fixedly arranged in the middle of the water storage chamber; the water inlet end of the filtering unit communicates with the collecting chamber, and the water outlet end of the filtering unit communicates with the water storage chamber; and the flow abandoning chamber, the water storage chamber and the collecting chamber are communicated with a water outlet pipe leading to the exterior of the spherical storage tank. The rainwater collecting and storing device can be flexibly arranged and float on the sea, the floating posture under sea surface wind wave impact is guaranteed, and the requirements for collecting and storing fresh water in remote islands can be met.

Description

technical field [0001] The invention relates to the technical field of rainwater collection, in particular to an offshore floating rainwater collection and storage device. Background technique [0002] Fresh water resources are one of the important factors limiting the strategic development of islands, and obtaining sustainable fresh water resources supply has become a prerequisite for island construction and development. For a long time, the way to obtain fresh water resources on islands has mainly relied on three methods: land fresh water resource transportation, seawater desalination, and island groundwater development. Ship transportation costs are high and cannot meet urgent needs; secondly, the cost of seawater desalination is too high, and research has proved that drinking desalinated seawater for a long time is not good for human health; the development of groundwater is likely to cause geological damage to islands and is not sustainable. At the same time, the above...
