Seawater sucking method and seawater conveying device

Abstract

The invention discloses a seawater sucking method and a seawater conveying device and relates to the field of seawater utilization. The seawater conveying device comprises a total seawater pipe (10), wherein one end of the total seawater pipe extends downwards to a deep part of the sea, at least one atmosphere communicating pipe (5) directly communicated with the atmosphere is arranged on a near-coast part of the total seawater pipe (10), a communication port of the atmosphere communicating pipe is lower than the lowest water level (2), an upper port of the atmosphere communicating pipe (5) is higher than the highest water level (3), a port (in a low level impounding reservoir (15)) of the total seawater pipe (10) is lower than the lowest water level (2), and a breathable cover (4) is installed on the upper port of the atmosphere communicating pipe (5); a gate valve (6), exhaust valves (14), a water injection valve (7), a gate valve (11), a coarse cleaner (1) and a fine cleaner (9) are installed on the total seawater pipe (10); the gate valve (6) and the gate valve (11) on the total seawater pipe (10) are both positioned below the lowest water level (2); and when the total seawater pipe (10) is filled with the seawater, the gate valve (11) is opened after the gate valve (6) is firstly opened in the process of high tide to realize that a large amount of low-temperature deep seawater with high quality can be introduced to the lands without energy consumption.

Description

technical field [0001] A seawater absorption method and a conveying device relate to the field of seawater utilization. Background technique [0002] The development and utilization of seawater has broad prospects. The development and utilization of low-temperature and high-quality deep seawater is more environmentally friendly, energy-saving and low-carbon. Now seawater is generally directly pumped by water pumps, but it consumes a lot of energy. Patent No.: ZL200810014173·3 A large amount Although the method, device and installation method for extracting and absorbing deeper seawater can extract and absorb without consuming energy, they also have shortcomings. They cannot make full use of atmospheric pressure and water level, and need to dig deeper and longer land to lay pipelines. Maintenance is also inconvenient. Contents of the invention [0003] The present invention proposes the following technical proposals for the above problems: seawater absorption method and de...
