The present invention relates to a device for improving the underwater environment, and more particularly, it is installed in a sea or a lake where red tide or green algae occur, and the like, to prevent the occurrence of red tide or green algae, and to prevent or remove the red tide or green algae that have already occurred. The present invention relates to an underwater environmental improvement apparatus capable of improving the environment.

The water, the stagnant lake, and the streams stagnated by the dam have a density change depending on the depth due to the temperature difference according to the water depth, and the water circulation occurs in the vertical direction, causing the midnight action by the water circulation. However, in the summer or winter, the temperature of the surface of the water is high and the temperature decreases as the water is lowered to a predetermined depth, so that a stratification occurs in which a stable layer is formed.

Due to the temperature distribution as described above, the density of the water surface is small at a predetermined depth, and the density increases relatively to the water, so that the circulation of water in the vertical direction is extinguished, and the circulation of water in the vertical direction is stopped. Due to the lack of deep water mixing, the self-cleaning action of the water is lost.

In order to prevent the contamination of water due to the above-mentioned stratification phenomenon, the compressed water is injected into the stratified water to circulate the deep water to the surface layer, or the water is circulated by external power of a rotating mechanism such as a wind fan. .

1 is a perspective view showing an underwater environment improvement device 10 for circulating water using a rotating mechanism according to the prior art, and FIG. 2 shows an installation state of the underwater environment improvement device 10 shown in FIG. 1. Side view.

As shown in Figs. 1 and 2, the underwater environment improvement apparatus 10 according to the prior art is provided with a main body 17 having an opening 18 formed in an intermediate portion thereof and penetrating up and down, and installed above the main body 17. A motor 11, a rotating shaft 13 connected to the motor 11 and installed in the main body 17, and three impellers 14, 15, and 16 installed on the rotating shaft 13. When the underwater environment improvement device 10 is installed in a lake or the sea, the floating body 20 is connected to the main body 17 so that a part of the device 10 is exposed from the water surface.

When the device 10 is installed and operated in a lake or the sea, water is introduced into the main body 17 from the lower part of the main body 17 by the thrust generation direction of the impellers 14, 15, and 16, The water 17 is discharged to the outside through the opening 18 formed in the middle portion of the main body 17. On the other hand, by the rotation of the impeller 14 provided in the upper air from the upper portion of the main body 17 is introduced into the main body 17 is a structure that is mixed with the water rising from the lower. Reference numeral 12 in FIG. 1 shows a structure that allows the components to be connected at a predetermined position.

However, when the water is circulated and mixed using the above-described underwater environment improvement device 10, since the deep water is larger than the density of the surface water, the deep water has a property of returning to the lower part, so the circulation and mixing of the water is not active. Since the temperature is maintained as it is and the state in which sunlight is irradiated to the surface water is maintained as it is, it is not possible to prevent pollution such as green algae or red tide generated from the surface water, and also has to use external power, so there is a problem that cannot be used semi-permanently.

The present invention has been proposed to solve the problems of the conventional apparatus for improving the underwater environment as described above, while improving the vertical temperature distribution of the sea or the lake, and actively circulating and mixing the surface water and the deep water, In addition, the purpose of the present invention is to provide an underwater environment improvement device that can prevent red tide organisms from coming into contact with the sun's rays, thereby suppressing the occurrence of green algae or red tide and effectively eliminating the existing green algae or red tide.

In FIG. 4, a floating body connected to the underwater environment improvement device 100 is omitted. As shown in FIG. 4, when the apparatus 100 for improving the underwater environment is installed in a lake or the sea, the heat medium circulating in the circulation pipe 115 is heated by the heat collecting means 110 for receiving sunlight. The heated medium is forcedly circulated by the circulation pump 117, and heat is transferred to the deep water so that the temperature of the deep water rises to form a high temperature part in the deep water portion. On the other hand, since the sunlight is blocked by the heat collecting means 110 in the surface water in which the underwater environment improving apparatus 100 is installed, the temperature rise of the surface water is stopped and a low temperature portion is formed in the surface water.

Therefore, convection occurs due to the temperature distribution of the deep water and the surface water as described above, and the water is circulated and mixed in the vertical direction while the deep water rises.

In the unstable temperature distribution as described above, the convection of the water by the forced convection means 120 allows the deep water to rise to the surface of the water, thereby actively circulating and mixing the water. By blocking sunlight, algae such as green algae can thrive or cannot survive, thereby preventing environmental degradation such as green algae and red tide.
