Description

Water vapor evaporation suppression unit, water vapor evaporation suppression device and artificial floating island

The present invention reduces meteorological disasters by suppressing excessive evaporation of water vapor from the sea surface, which is one of the sources of the frequent occurrence and intensification of abnormal weather, normalizes the circulation of the atmosphere, and makes effective use of water vapor. The present invention relates to an artificial floating island equipped with a water vapor evaporation suppressing unit, a water vapor evaporation suppressing device using a water vapor evaporation suppressing unit, and a water vapor evaporation suppressing device.

Due to the decrease in the cooling efficiency of seawater at the extreme points such as defrosting of the north and south poles, activation of submarine volcanoes, and global warming, the seawater temperature rises around the equator further promotes excessive evaporation of water vapor and disturbs the atmospheric circulation, and is saturated everywhere. The situation has occurred, and meteorological disasters caused by frequent intensification of tornadoes, typhoons, torrential rains, and heavy snowfalls are widespread and have a great impact on human society.

Despite advances in technology in all fields such as revetment breakwaters, drainage facilities, and weather forecasts, excessive evaporation of water vapor from the sea surface around the equator causes frequent low pressure systems, which intensifies the energy and disturbs the atmospheric circulation. Before the widespread diffusion of water vapor, there is a reality that local catastrophic meteorological disasters are occurring in many areas, and the current situation is that we cannot cope with this enormous amount of energy and are trying our best to escape.

Therefore, as an invention made to prevent excessive evaporation of water vapor from the sea surface, for example, the apparatus disclosed in Japanese Patent Application Laid-Open No. 50-9233 (Patent Document 1) and Japanese Patent No. 2727128 (Patent Document 2) is known. ing.

In these devices, a sheet is stretched between a plurality of floating bodies floating on the sea to prevent water vapor evaporation from the sea surface below the sheet, and the sheet is made of flexible plastic such as vinyl chloride. Therefore, it is possible to transport the floating body and the sheet in a folded state and extend them at the installation location, or to combine the sheets with the floating bodies arranged at predetermined intervals on the sea. Provided is a device for preventing the evaporation of water vapor from the sea surface, which is highly assembling and portable.

However, in each of the above devices, it is necessary to install a large number of anchors in order to keep the sheet stretched while preventing drifting from the installation location. If the floating body is steered to change the direction of the device according to the tidal current, the anchor should be installed only on the upstream side, but then it cannot be installed in a place where the tidal current reverses.

Moreover, each of the above devices is regarded simply for the purpose of preventing the evaporation of water vapor from the sea surface, and attention is not paid to the effective use of water vapor from the sea surface.

In this way, conventional equipment is all about preventing the evaporation of water vapor, and it does not consider moving it from a fixed point installation location, and if it were to be moved to a different installation location, it would be a great deal. It requires a lot of effort.

Japanese Unexamined Patent Publication No. 50-9233 Japanese Patent No. 2727128

The present invention suppresses the emission of excessively evaporating water vapor in the sea near the equator to the air as a countermeasure against the enormous energy source of abnormal weather, reduces abnormal weather disasters, and normalizes the atmospheric circulation. The challenge is to store water vapor and make it available.

The present invention made to solve the above problems is a water vapor evaporation suppressing unit installed on the ocean and suppressing water vapor evaporation from the sea surface, and is a box having four or three side surfaces and a top surface and an open bottom surface. It consists of a body and a plurality of floats attached to the box, and the inside of the box is divided into two layers, an upper layer and a lower layer, by a guide surface inclined so as to be lowered toward one of the side surfaces. A water storage unit capable of introducing water vapor evaporated from the sea surface below the box into the box and storing water in which the water vapor is condensed in a position located at a lower position of the guide surface in the upper layer. It is characterized by having.

By introducing and collecting the water vapor evaporated from the sea surface at sea in this way inside the box, excess water vapor evaporation from the sea surface is suppressed, and the water vapor inside the box is condensed mainly at night when the temperature drops. This fresh water is effectively used because it becomes water droplets and is stored in the water storage section along the side surface or guide surface of the box.

Further, the box body is composed of a plurality of pillars erected on the float, a string-shaped member connecting the upper portions and lower portions of the respective pillars, and a daylighting sheet that transmits sunlight, and the side surfaces and the above-mentioned side surfaces. The top surface is formed by the daylighting sheet attached to the string-shaped member, and the guide surface is attached to one side of the daylighting sheet to the string-shaped member extending between a predetermined side surface and the opposite side surface of the box body. When it is characterized in that it is formed by inclining the other side toward the water storage portion, it can be easily transported from land to sea without being bulky by using, for example, a flexible resin daylighting sheet. Further, when a string-shaped member attachment portion is formed on a resin daylighting sheet and assembled in advance in a three-dimensional shape, the string-shaped member stretched between columns after being easily transported from land to sea without being bulky. This unit can be completed by simple construction by simply attaching a daylighting sheet.

Further, when a light-shielding portion is provided above the water storage portion, for example, water vapor can be condensed in the vicinity of the light-shielding portion and stored in the water storage portion even during the daytime, so that it can be efficiently stored in the water storage portion. Can produce fresh water.

Furthermore, when the top surface of the box is inclined so as to be higher toward the upper side of the water storage portion, this inclination guides water vapor upward, that is, toward the water storage portion. , It is possible to efficiently generate fresh water.

The water vapor evaporation suppressing device using the water vapor evaporation suppressing unit is formed by connecting a plurality of the water vapor evaporation suppressing units, and in particular, the water vapor evaporation suppressing unit exhibits an isosceles triangle shape or a fan shape having a predetermined central angle. By connecting the ends of the floats to each other, the water vapor evaporation suppressing unit has a disk shape as a whole.

Further, the floats are composed of three types of floats, which are rod-shaped outer peripheral floats, middle peripheral floats, and inner peripheral floats, and are multiple concentric by connecting the ends of the respective floats of the adjacent water vapor evaporation suppressing units. When forming an annular floating row, the outer peripheral floating row and the inner peripheral floating row can be maintained at equal intervals with a relatively simple configuration, and columns erected at both ends of the middle peripheral floating row. A string-shaped member for forming a guide surface can be easily provided by connecting the spaces with a string-shaped member.

Further, by arranging a plurality of the water vapor evaporation suppressing units connected in the circumferential direction so as to surround the outer periphery of the water vapor evaporation suppressing unit connected in the circumferential direction, a ring formed by two or more connected water vapor evaporation suppressing units is formed. In the case of the above, a large-scale water vapor evaporation suppressing device can be configured to suppress excessive water vapor evaporation from a wider range of sea surfaces.

Further, the top surface of the box is formed so that the outer peripheral floating side is low and the inner peripheral floating side is high, or the top surface of the box is formed so that the outer peripheral floating side is high and the inner peripheral floating side is high. When the outer circumference side is high and the inner circumference side is low, the structure is suitable for land and the sea near the island, and conversely, the outer circumference side is low and the inner circumference side is low. When it is raised, it is suitable for land and offshore far from the island.

Further, when a central float having an anchor is arranged in the center and the central float and the inner peripheral float are connected to each other, the position of the central float is simply fixed by the anchor to fix the position of the entire device. Since the position can be fixed, it can be installed easily.

In addition, if the central float is equipped with at least one of a heliport, rescue equipment equipment, a solar power generator, a wind power generator, a hydroelectric generator, a lighting equipment, a transmission / reception equipment, and a propulsion means, it is at sea. It is possible to utilize security and move to any point.

An artificial floating island using the water vapor evaporation suppressing device is formed by accommodating the water vapor evaporation suppressing device in the holes of a large plate-shaped member having a plurality of circular holes formed therein. According to this artificial floating island, the water stored in the water storage section can be used as domestic water in the artificial floating island, and it becomes possible to make an artificial floating island in which a large number of people can live for a long period of time.

According to the present invention, it is possible to suppress excessive evaporation of water vapor from the sea, etc., and it is urgent to move and deploy it appropriately and seasonally in consideration of quantity, scale, and cooperation with meteorological satellites based on international cooperation. It has the potential to mitigate and resolve major disasters caused by abnormal weather, which is an issue.

Mitigating and adjusting the excessive evaporation of water vapor not only controls the frequent intensification of tornadoes, typhoons, torrential rains, and heavy snowfalls, but also moderate water vapor is diffused over the sky by high pressure to bring about even rainfall and normalize atmospheric circulation. .. It can be a global disaster mitigation method by restoring the cooling efficiency of seawater at the extreme points, preventing air pollution, protecting green areas, and preventing excessive evaporation of water vapor around the equator.
