Embodiment Construction
[0016] figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 is the appearance diagram of this device,
[0017] See Figure 7 , is the sectional structure diagram of the device, and is also the system diagram of the whole device, which is composed of a ballast chamber, a filter and a water storage tank.
[0018] See Figure 7 : Ballast chamber--filled with "① ballast", can be filled by concrete, or ordinary metal, or rock blocks, etc., its function is to match enough heavy objects to make the whole device sink into the water against buoyancy.
[0019] Filter - "③ filter tube" in the filter is made of molecular permeable membrane. Under the action of pressure, the water molecules in the seawater penetrate through the filter tube of the filter and gather into the water storage bucket in the device. The filter is connected with the water storage barrel through a connector, and the filter can be easily disassembled and replaced. The filter tube can also be replaced repe...

The invention relates to a miniature easy ocean fresh water (clean water) fetching bucket which comprises a ballast weight bin, a filter and a water storage bucket. The miniature easy ocean fresh water (clean water) fetching bucket adopts the basic principle that enough loads are arranged in the ballast weight bin, and the ocean fresh water fetching bucket is immersed into water at a suitable depth so as to form a pressure difference large enough between the interior and the exterior of the ocean fresh water fetching bucket. A filter tube of the filter in the ocean fresh water fetching bucket is made of a molecular permeable membrane; water molecules in seawater penetrate through the filter tube of the filter under the action of pressure, permeate and gather to the water storage bucket of the ocean fresh water fetching bucket while original air in the bucket is expelled from a valve at the top of the bucket; the ocean fresh water fetching bucket is lift back onto the water after a certain amount of fresh water is collected for a period of time; and the fresh water can be obtained by opening the valve. The miniature easy ocean fresh water (clean water) fetching bucket is easy to fetch fresh water from oceans resembling fetching water from wells and can fetch clean water from different water bodies if different filter tubes are replaced.
Description
Technical field [0001] The invention relates to a small and simple seawater desalination facility. Background technique [0002] At present, the use of permeable membranes for seawater desalination usually requires large-scale equipment and consumes high amounts of energy, which greatly restricts its application. Today, people go to sea to sail, live in isolated islands, work in the ocean, etc., and fresh water is still mainly supplied by land transportation. People's survival depends on fresh water all the time, and fresh water restricts people's development and utilization of the ocean. Contents of the invention [0003] The invention is a small and simple seawater desalination device, and the whole device is composed of a ballast chamber, a filter and a water storage barrel. The basic principle is: arrange enough heavy objects in the ballast chamber, sink the device into the water to an appropriate depth, and form a large enough pressure difference inside and outside ...
