Abstract

FIELD: methods and apparatus for producing or collecting water.

SUBSTANCE: invention relates to devices for producing fresh water from water vapours contained in ambient air, and can be used to produce fresh water mainly in coastal areas with high tide intensity. Device comprises a cooled partition separating the condensation zone of water vapour and cooling water, a vessel for receiving fresh water. Cooled partition is made in the form of shields fixed along the external side surface of the pool filled with sea water at high tide and emptied at low tide. Pool is equipped in the lower part with weirs with opening and closing doors so that their ends opposite to the fixed ones are in a free state above the fresh water collection vessel. Shields are fixed so that they can be pulled out when the pool is empty at low tide and located at angle of 100 to 150 degrees relative to the vertical plane with rigid fixation and move in until it touches the external side surface of the pool when it is filled during high tide.

EFFECT: reduced area occupied by shields during high tide.

Description

The invention relates to devices for obtaining fresh water from water vapor contained in the surrounding atmospheric air, and can be used to obtain fresh water mainly in coastal areas with high tides and low tides.

The prototype of the invention is the device described in [1].

The device contains a cooled partition separating the condensation zone of water vapor and cooling water, and a vessel for receiving fresh water. The cooled partition is made in the form of shields fixed around the perimeter and located at an angle in the direction from the pool, which is filled with sea water during high tide and emptied during low tide. The pool is equipped in the lower part with spillways with opening and closing doors so that their ends, opposite the fixed ones, are in a free state above the container for collecting fresh water. To provide strength to the fastening of the shields, additional supports are provided in their central part, dug into the ground, and the ends of the shields attached to the pool are located in close proximity to the spillways.

The disadvantage of the device is that the shields occupy a fairly large area and prevent any objects from being located and moving near the pool.

The purpose of the invention is to reduce the area occupied by shields during high tide.

The goal is achieved by the fact that the shields are fixed so that they can be pulled out when the pool is filled with sea water during low tide and positioned at an angle of 100 to 150 degrees relative to the vertical plane with rigid fixation, and moved in until it comes into contact with the outer side surface of the pool when it is devastation at high tide.

The design of the device is shown in Fig. 1.

The device consists of a pool 1, filled with sea water during high tide, in the lower part of which there are spillways 2, initially closed with special doors 3. To the side surface of the pool 1 along its perimeter in the immediate vicinity of the spillways 2 and above them using fastening devices 4, shields 5 are installed. Shields 5 are fixed on the side surface of the pool 1 from its outer side so that they can extend when the pool 1 is filled with sea water at low tide and are located at an angle of 100 to 150 degrees relative to the vertical plane with rigid fixation, and move until it comes into contact with the outer side surface of pool 1 when it is emptied during high tide. The ends of the shields 5 in the extended state are in a free state above the container for collecting fresh water 6.

The device works as follows. At high tide, pool 1 is filled with seawater at a temperature below ambient temperature, which is typical for almost all regions in the summer. In this case, the spillways 2 are in their original position (closed by doors 3). After low tide, when the level of sea water outside the pool is significantly lower than the level of the spillways 2 doors 3 open - the outflow of sea water into the environment begins. The cold sea water flowing through the weirs 2 will cool the extended shields 5, thereby creating a condensation zone on their upper surface. Due to their inclination, the moisture condensed on this surface of the shields 5 will flow into the fresh water collection container 6, from where it will be removed for further use before the next tide. Folding the panels 5 while filling the pool 1 with sea water at high tide will reduce the area occupied by the structure.
