Description

Subsea Sediment Pumping Equipment {A SUBMARINE DEPOSIT PUMPING DEVICE}

The present invention relates to a seabed sediment pumping device, and more particularly, to a seabed sediment pumping device capable of supplying sediment on the seabed to surface seawater.

In general, upwelling in the ocean refers to a phenomenon in which deep seawater is eluted to the surface seawater. This phenomenon can be configured to increase phytoplankton by supplying nutrient salts such as nitrogen and phosphorus contained in deep water in deep seas to surface waters with relatively poor nutrient salts, thereby forming a good fishery in surface waters. .

Examples of mass uptake include the West Coast of South America and the West Coast of Africa. This is mainly due to the deep seawater rising to the surface to compensate for ocean currents in the western coastal waters of the continent, which is rich in phytoplankton by light and nutrients, forming a rich fishing ground. have. It is estimated that this Yongyong sea area accounts for about half of the total fish production, although it covers only 0.1% of the entire ocean.

Therefore, techniques have been developed for artificially pumping nutrients in deep water over most of the deep seas that cannot form a good fishery due to lack of nutrients on the surface seawater and supplying them to the surface seawater to form a good fishery.

However, in the conventional case, even if the deep water is artificially pumped and supplied to the surface seawater, it is difficult to supply the nutrients to the surface seawater as much as required, since the deep water is pumped to a limited position.

In addition, performing the pumping of such deep water requires continuous power supply. However, when supplying power using solar heat as in the prior art, there is a problem that the power supplied is limited depending on weather conditions.

In the present invention, in order to solve the above problems, it is to provide a seabed sediment pumping device that can supply the deep sea water containing a high concentration of nutrient salts from the sea bottom.

In addition, it is to provide a subsea sediment pumping device that can be continuously driven without being affected by external conditions such as weather.

An object of the present invention described above, the stirrer to form a deposit turbid liquid by impacting the sea bottom at the lower end of the yongyong pipe, and the turbidity liquid is installed in the upper portion of the yongung pipe rises along the yongyong pipe It can be achieved by a subsea sediment pumping device including a pumping pumping pump.

At this time, the upper side and the lower side of the water pipe includes an opening, the deposit turbidity is preferably configured to rise along the water pipe by the surrounding water pressure.

Here, the stirrer may include a motor and a rotating body that is rotated by the motor, so that the rotating body impacts the sea bottom when the motor is driven to form the deposit turbidity.

In addition, the rotating body is installed to be rotated in the horizontal direction by the motor, the stirrer is preferably moved on the sea bottom while forming the deposit turbidity by the rotation of the rotating body.

Alternatively, the stirrer may include an end portion of the tube extending from the upper side along the upwelling pipe, and may be configured to impact the sea bottom using water pressure of water sprayed from the tube to form the deposit turbidity. .

In this case, the tube may be configured to use a separate pump, or to supply water in the lower direction of the tube by maintaining the water level higher than the sea level.

And, the end of the tube is sprayed with water in a direction oblique to the bottom surface, the stirrer is preferably moved on the bottom while forming the deposit turbidity when water is injected from the end of the tube.

On the other hand, the pump pump may pump the deposit turbidity, it may be supplied to the adjacent sea surface through the turbidity supply hose.

In addition, the turbidity supply hose is preferably controlled to supply the deposit turbidity in accordance with the sea current direction of the sea surface.

In addition, it may be configured to further include a generator for generating power using the temperature difference between the sediment turbidity and the sea level rising along the water pipe.

Here, the generator preferably supplies power to the stirrer or the pump.

According to the present invention, it is possible to supply a high concentration of nutrients from the deep water to the surface seawater, so that the economic profit can be expected through the formation of a new fishery.

In addition, the use of an energy source capable of continuously supplying power regardless of weather conditions can improve the efficiency of supplying nutrients to surface water surface.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the seabed sediment pumping device according to a first embodiment of the present invention.

1 is a cross-sectional view showing a cross section of the seabed sediment pumping device 1 according to the present invention.

As shown in FIG. 1, the present invention includes a water conduit 10 for forming a moving path of deep water, an agitator 20 for forming a turbid liquid with sediments on the sea bottom, and a sediment rising along the water conduit 10. It may be configured to include a pump pump 30 for pumping the turbid liquid.

The water pipe 10 may be configured in a tubular shape having a length sufficient to extend from the sea surface to the bottom surface of the sea. The lower end is located at the bottom of the sea floor and the upper end is extended to be adjacent to the sea surface to form a path for deep water in the sea bottom.

Here, the water pipe 10 may have a length or more than the height (H) of the sea surface to be able to move flexibly according to the current, it may be composed of a flexible (flexible) material. Alternatively, it may be made of a rigid material so as to stably secure the flow path while resisting currents.

At this time, it is preferable that the upwelling pipe 10 is configured such that predetermined portions of the upper side and the lower side form the opening 11, respectively. Therefore, the portions in which the openings 11 are formed, respectively, can form a continuous pressure distribution with the adjacent portions. For example, when the water pipe 10 is installed from the sea level to the sea bottom, the opening formed in the upper portion of the water pipe 10 may have only a water pressure corresponding to atmospheric pressure similar to the sea level. In addition, the opening formed at the lower side of the water pipe forms a continuous pressure distribution with the sea bottom, and when a difference in water pressure occurs in a predetermined direction, seawater may flow in a low water pressure direction.

Therefore, when the pump pump 30 continuously pumps water above the water pipe 10, water flows from the lower end of the water pipe 10 and rises due to the pressure distribution inside the water pipe 10. It is possible to supply it to surface seawater. In this case, when the upwelling pipe 10 forms a closed flow path except for the opening 11 provided on the upper side and the lower side, the deep water of the sea bottom including a large number of nutrient salts such as organic matters is formed on the upper side of the upwelling tube 10. Can only supply

On the other hand, the stirrer 20 is installed at the lower end of the pipe (10). Then, the sediment layer on the sea bottom is stirred to form a deposit turbid liquid.

As described above, the deep water of the deep sea contains many nutrient salts such as various minerals necessary for the growth of living organisms. Furthermore, these materials accumulate at the bottom of the deep sea, forming yuni. Therefore, the present invention can agitate these deposits using the stirrer 20 to form a thick concentrate deposit. In addition, the high-density sediment turbidity liquid formed in the stirrer 20 may rise along the permeation pipe 10 and be supplied to the surface seawater.

Of course, even when the stirrer 20 is not provided, it is possible to supply the nutrients necessary for the growth of living organisms by supplying deep water containing minerals to the surface sea water, but using the stirrer 20 as in the present invention. When used to form a high concentration of sediment turbidity, it is possible to supply nutrients to the surface seawater more effectively. Furthermore, feeding the sediment turbidity can induce phytoplankton growth in surface waters. At this time, phytoplankton absorbs carbon dioxide to perform photosynthesis, and when phytoplankton induces proliferation in a wide range, it can also be expected to reduce the amount of carbon dioxide in the atmosphere.

As shown in Figure 1, the stirrer 20 is provided at the lower end of the water pipe 10, when the seabed sediment pumping device (1) is installed in the deep sea, it is located adjacent to the sea bottom. Here, the stirrer 20 may form a deposit turbidity by stirring the deposit while applying a predetermined energy to the deposit on the sea bottom.

Here, the manner in which the stirrer 20 impacts the deposits on the sea bottom may be configured in various forms. In the present embodiment, it can be configured using the rotating body 22 that rotates by using the power of the motor 21. Here, the rotating body 22 may be configured in the form of a propeller, a screw or a wheel.

As shown in FIG. 1, in this embodiment, the rotating body 22 may be configured by using a screw having a spiral protrusion formed on an outer circumferential surface thereof. At this time, the rotor 22 is rotated by the motor 21, the projection formed on the outer peripheral surface can form a deposit turbid liquid while stirring the deposition of the sea bottom.

At this time, the rotating body 22 according to the present embodiment is preferably configured to have a horizontal axis of rotation. In this case, it is possible for the screw-shaped rotary body 22 to move on the sea bottom by the reaction force generated during the agitation while stirring the sea bottom by the motor 21. That is, instead of continuously stirring only a predetermined position during the operation of the stirrer 20, it is possible to perform the stirring of the deposit while changing the position on the sea bottom. Therefore, it is possible to stir evenly the seabed surface while preventing the specific position of the seabed surface from being dug and the rotating body 22 failing.

On the other hand, the stirrer 20 may further include a case 23 that can continuously protect from the lower end of the water pipe 10, the motor 21 and the rotating body 22. In addition, at least one hollow 24 may be formed on an outer circumferential surface of the case 23. Therefore, the water pressure inside the stirrer can be continuously distributed with the water pressure of the adjacent seawater, and the movement of the water flow can be smoothly generated when the water pressure difference occurs. In addition, when the deposit turbidity rises along the upwelling pipe 10 by the pump pump 30, adjacent deep water may flow into the agitator to form the deposit turbidity.

At this time, the case 23 is provided in a shape in which the cross section becomes wider toward the lower side, and may form a space in which the deposit turbid liquid is accommodated when the rotor 22 stirs the sea bottom. In this case, it is possible to minimize the mixing of the sediment turbidity with the deep water and to rise to the upwelling pipe 10 while maintaining a high concentration.

On the other hand, the pump pump 30 is installed on the upper side of the water pipe 10, it is possible to pump the sediment turbidity rising along the water pipe (10). That is, the lower end of the water pipe 10 by the pumping of the pump pump 30 has a relatively low water pressure than the adjacent water level. Therefore, the deep water is continuously introduced into the stirrer 20 to form a sediment turbidity, which rises on the upwelling pipe 10.

Pumping pump 30 is preferably pumped sediment turbidity that rises along the riser pipe 10 at a predetermined depth lower than the sea level. In this case, even if the level of the sea level changes according to external conditions, the water pressure of a predetermined size or more can be maintained while pumping the deposit turbidity at a lower position than the sea level.

In addition, the pump pump 30 may supply the sediment turbidity to the surface seawater of the adjacent sea surface through the turbidity supply hose 31. Therefore, the area adjacent to the point where the seabed sediment pumping device 1 according to the present invention is installed can be sufficiently supplied with nutrients necessary for the growth of living organisms in the surface seawater, thereby forming a good fishing ground.

At this time, the turbidity supply hose 31 is preferably configured to control the direction of supplying the deposit turbidity. In addition, the turbidity supply hose 31 is configured to detect the direction of the current changes according to the region and weather conditions, it is more preferably configured to control the direction in which the turbidity is supplied reflecting this.

On the other hand, the seabed sediment pumping device 1 according to the present invention may further comprise a generator 40 for generating electric power by using the temperature difference between the turbidity of the sediment rising along the water pipe 10 and the sea surface. . Depending on the region, the temperature difference between the surface seawater and the sediment turbidity generated in the deep water may reach 20 ° C to 30 ° C, so that it is possible to generate a seawater temperature generator.

In general, the turbine of the generator 40 may include a low boiling medium therein, and may be cooled or condensed by a low temperature sediment turbidity liquid raised in a deep sea, and then heated and vaporized by surface seawater at room temperature. It is possible to produce electric power using the generator 40 using such a circulation method, the specific configuration can be configured using a seawater temperature difference generator generator disclosed in the prior art.

Furthermore, the generator 40 is preferably configured to supply power to the stirrer 20 or the pump pump 30. Seawater temperature generators do not require auxiliary systems for energy storage, are economical in construction and operating costs, and have an adequate amount of net energy output. Therefore, even if each is installed separately in the deep sea it can be possible to continue driving without additional power.

In the above, the seabed sediment pumping apparatus 1 which forms the deposit turbid liquid using the rotating body 22 was demonstrated. The above-described stirrer 20 is configured using the rotating body 22 having a horizontal axis of rotation, but the present invention is not limited thereto. It is also possible to comprise using the rotating body which has a rotating shaft of a vertical direction, and can also comprise using another apparatus. Hereinafter, another embodiment of the agitator will be briefly described with reference to FIG. 2.

2 is a cross-sectional view showing a seabed sediment pumping device according to a second embodiment of the present invention. Here, the stirrer 20 which applies impact energy by the hydraulic pressure more than predetermined pressure to the said sea bottom surface and forms a deposit turbid liquid can be used.

As shown in FIG. 2, the seabed sediment pumping apparatus 1 according to the present embodiment may further include a separate tube 50 extending along the upwelling pipe 10. Here, the tube 50 forms a flow path through which water is introduced from the upper side and is supplied downward.

Specifically, the upper end of the tube 50 is configured to supply water at a predetermined pressure or more. In addition, the lower end 51 of the tube 50 is installed inside the stirrer 20, and the water moving through the tube 50 has a predetermined hydraulic pressure through the lower end 51 of the tube 50. It is sprayed, and it can be used to stir the sediment stack on the bottom.

As such, in order for the water passing through the tube 50 at the lower end 51 of the tube 50 to be sprayed with a predetermined water pressure, the water passing through the inside of the tube 50 at a height of the sea level is a certain pressure higher than atmospheric pressure. Should be maintained. To this end, the tube 50 may be configured to continuously receive water from the water tank 52 of a position higher than the sea level, to maintain a high water pressure corresponding to the height from the sea surface to the water tank 52. have. Alternatively, water may be supplied to the tube 50 by using a separate pump 53. In this embodiment, as shown in Figure 2, by using the height of the water tank 52 and the pump 53 at the same time was configured to be sprayed with water at a high water pressure on the stirrer (20).

Meanwhile, the lower end 51 of the tube 50 installed inside the stirrer 20 may be configured to spray water in a direction oblique to the sea bottom. In this case, the water is sprayed to form a deposit turbid liquid, and when the lower end 51 and the bottom surface of the tube 50 are installed adjacent to the agitator ( 20) it is possible to move on the sea floor.

Compared to the above-described embodiment, the present embodiment does not include a separate driving device at the lower end of the stirrer 20, and thus has an advantage of easy inspection and repair. In addition, the water is continuously sprayed on the stirrer 20 at a predetermined water pressure, there is an advantage that can prevent the phenomenon of the inside of the stirrer blocked by the deposit turbidity.

Figure 3 is a schematic diagram showing a working ship is installed seabed sediment pumping device according to the present invention.

The subsea sediment pumping device 1 according to the present invention can be installed independently, such as to drive a pile at a predetermined position in the deep sea. However, as shown in FIG. 3, the subsea sediment pumping device 1 is installed below the work line 2 to change the position of the work line 2 so as to facilitate management and position search after installation. A fishery can be formed by supplying the sediment turbidity of the seabed to a predetermined range of sea areas. At this time, it may be configured to include a plurality of seabed sediment pumping device below the work line, it is also possible to simply drive by using a work line having one seabed sediment pumping device as shown in FIG.
