The invention provides a lifting system for extracting seawater, which comprises a water taking buffer cabin with a water taking buffer cavity, a water taking header pipe and a seawater lifting pump installed in a pump cabin, the water taking buffer cavity is located below the sea level, the lower end of the water taking header pipe is used for extending into seawater, the upper end of the water taking header pipe is communicated with the water taking buffer cavity, and the seawater lifting pump is installed in the seawater lifting pump. And a pump inlet of the seawater lifting pump is communicated with the water taking buffer cavity. The seawater lifting pump only needs to lift seawater in the water taking buffer cabin to a user at a set height, energy consumption is reduced, the seawater lifting pump is installed in the pump cabin, the seawater lifting pump only needs to adopt an in-cabin pump, an underwater pump is not needed, the purchase cost of the seawater lifting pump is reduced, and the cost of the seawater lifting pump is reduced. Compared with an underwater pump, the in-cabin pump is more convenient to maintain, lower in maintenance cost and longer in service life; the seawater lifting system can be suitable for being used under high sea conditions, can lift seawater in a large-flow and large-depth mode, can be laid and recycled and is high in flexibility.
本发明提供一种用于提取海水的提升系统,包括具有取水缓冲腔的取水缓冲舱、取水总管及安装在泵舱中的海水提升泵,取水缓冲腔位于海平面的下方,取水总管的下端用于伸入至海水中,取水总管的上端与取水缓冲腔相连通,海水提升泵的泵入口与取水缓冲腔相连通。海水提升泵所做的功只需将取水缓冲舱中的海水提升至设定高度处的用户即可,降低了能耗,且海水提升泵安装在泵舱中,使得本海水提升泵采用舱内泵即可,无需采用水下泵,降低了海水提升泵的采购成本,且舱内泵相比于水下泵维护更加方便、维护成本更低,使用寿命也更长;该海水提升系统能适应在较高海况条件下使用,能实现大流量、大深度提升海水,且可布放、回收,灵活性高。
