Upwelling flow generator

Abstract

The BioFan fluid theory, which has been developed as a principle for water cultivation since 2006 and has achieved numerous successes, is the culmination of a theory based on energy conservation. Because it was designed so that a large amount of energy is not consumed in the flow rising from the seabed, there was a problem in that it could not directly draw up large amounts of water from the seabed of deep lakes, bays, or oceans. [Solution] A new theory was constructed to directly draw large amounts of water from depths where photosynthesis is declining. By introducing three design condition equations to fully satisfy this theory, it became possible to regenerate large and deep lakes, bays, and oceans into abundant fishing grounds and suppress the ocean acidification that is currently a problem.

Description

Detailed description of the invention in the field of technology

[0001] This invention relates to a technology that directly draws up large quantities of water from the seabed where sunlight has weakened and photosynthesis is not taking place, meaning that oxygen has also been depleted, making it impossible for zooplankton such as rotifers, water fleas, and krill, as well as fish and shellfish, to survive. By spreading this water on the surface of lakes and oceans, photosynthesis is activated, and carbon dioxide (H2CO3), which is a concern due to acidification, is converted into phytoplankton and rendered harmless. At the same time, the large amount of oxygen produced by photosynthesis makes it possible for zooplankton and fish and shellfish to survive, thereby revitalizing lakes, bays, and oceans into abundant fishing grounds. [Background technology]

[0002] The development of a technology that uses a biofan to cultivate water, supplying oxygen to the seabed to promote the growth of fish and shellfish, and then spreading the seabed water over a vast surface area to expose it to wind and sunlight, thereby removing water odors and COD that cannot be removed by microorganisms using the ultraviolet rays of sunlight, has been ongoing since 2006. It has now grown to the point where it is recognized as a principle of water cultivation, but there have yet to be any reported examples of it revitalizing lakes, bays, or oceans into rich fishing grounds.

[0003] The development of biofans up to that point had been the culmination of technologies centered on energy conservation. For example, if the flow velocity of water rising from the bottom of the water increases, energy is consumed in the flow at a rate proportional to the square of that velocity. To prevent this, the water-pulling plates were designed to be placed away from the axis of rotation. As a result, it was not possible to directly draw up water from deep places. This was the cause of the impasse. [Disclosure of the Invention]

[0004] A common characteristic of lakes, bays, and oceans is that as you go deeper, sunlight weakens, photosynthesis declines, oxygen production ceases, and there are always areas where zooplankton and fish can no longer survive.

[0005] Because nutrients are not synthesized by phytoplankton in that area, the water contains not only nutrients but also carbon dioxide, which is a problem that causes ocean acidification. If this water is brought up to the surface where photosynthesis is active, the nutrients and carbon dioxide will combine to form phytoplankton, the acidification will be resolved, zooplankton will proliferate with the oxygen produced by photosynthesis, and sardines will come to life, attracting tuna, which in turn will gather, reviving the vast body of water into a thriving fishing ground.

[0006] It is generally said that areas with strong upwelling currents become prime fishing grounds, and this device was named the Upwelling Current Generator based on that assertion. The objective of this invention is to achieve results worthy of its name. Means for solving this problem

[0007] When a biofan is floated in the deep part of a lake and its blades are turned, the water in the deep part instantly starts moving towards the biofan. Focusing on the unique fluid dynamics of the biofan that constitutes this water cultivation principle, the equation [Equation 1] was created by considering the continuous rotation of the blades as shown in Figure 1.

[0008] The challenge is to retrieve the water from the seabed at a depth of Hm using this [Equation 1] at a rate of M0m per minute. 3 The goal is to change the way the water spreads out in the direction of the water surface, from a width W0 to a narrower width W.

[0009] First, as shown in Figure 1, three webbed plates with width W0 and length R0 are rotated to lift the water from the bottom. The amount of water M0 and the length R0 of the webbed plates are plugged into equation [Equation 1] to calculate H, which then determines M0 and H0 so that the required water depth is achieved. 3 The power P0 required to lift the volume of water from depth H is also calculated using [Equation 2].

[0010] Next, in order to change the flow that spreads out toward the water surface with a width of W0 to a flow that spreads out with a narrow width of W, three water-spreading plates with width W and length R are attached on top of the water-spreading plates W0 and R0 as shown in Figure 2, and the power P required to rotate these water-spreading plates so that the amount of water M that is pumped up is equal to the amount of water M0 that is pulled up from the bottom is calculated using [Equation 3].

[0011] The problem can be easily solved by using the power obtained by adding the powers P and P0 together, (P0+P), to rotate six webbed boards: three with width W0 and length R0, and three with width W and length R.

[0013] In April 2024, there was a request from China to create a biofan that directly pumps water from a depth of 7 m in a lake where the temperature difference between the water surface and the bottom is 6°C. Therefore, a biofan modified so that H is calculated to be 7 m by Equation (1) was floated on the lake for actual measurement, and there was a report that it was indeed observed that water rose directly from the bottom where H = 7 m.

[0014] Through this experiment, it can be said with certainty that the flow caused by the upwelling flow generator can be analyzed by the theories of Equations (1), (2), and (3) up to a depth of several tens of meters. However, there must be people who have doubts when pumping water from a depth of as much as 100 m in lakes, bays, or the ocean.

[0015] Therefore, first, let's calculate the upwelling flow generator that is floated in Tokyo Bay where the bottom at 10 m is said to be decaying. Rotating three water scraping plates with W0 = 3 m and R0 = 2.06 m, the electric power P0 required to pump 300 m 3 of water per minute from the bottom at a depth of 10 m is calculated by Equation (2) with M0 = 300 m 3 to be "P0 = 246.9 [W]". Also, assuming that the temperature difference Δθ between the water surface and the bottom is 10°C, when calculating the pumping depth H of 300 m 3 of water per minute by Equation (1), H = 10 m is calculated.

[0016] From the above explanation, it is possible to calculate an upwelling flow generator that floats three water scraping plates with W0 = 3 m and R0 = 2.06 m, rotates with an electric power of P0 = 246.9 [W], and pumps 300 m 3 of water per minute from the bottom at a depth of about 10 m, causing a flow that spreads in the water surface direction with a width of W0 = 3 m.

[0017] Next, we want to reduce the width of the flow that spreads with a width of W0 of 3 m to 1 m. Therefore, we will attach and rotate water scraping plates with W = 1 m and R = 3.6 m on top of the plates with W0 and R0. At this time, the required electric power is calculated by Equation (3) to be "P = 740.7 [W]", so the electric power required to rotate the six assembled water scraping plates is, (P0 + P) = (246.9 + 740.7) = 987.6 [W] could be estimated.

[0018] As described above, with a solar power of only 988 [W], six water scraping plates are rotated, including three water scraping plates with W0 = 3 m and R0 = 2.06 m and three water scraping plates with W = 1 m and R = 3.6 m, to pump water from the bottom of 10 m at a rate of 300 m per minute. 3 It was also possible to calculate an upwelling current generating device that pumps water at a rate of 300 m per minute from the bottom of 10 m and causes a water flow with a width of 1 m in the water surface direction.

[0019] When the device calculated in this way is floated in Tokyo Bay, the area that spreads in the water surface direction in one day is calculated by the following formula. TIFF2026050285000004.tif18109 Therefore, the annual spreading area is 365 times this value, spreading over a water surface of 12.6 km × 12.6 km, and 157,680,000 tons of water pumped from the bottom of 10 m annually can be exposed to sunlight. By eliminating the acidification of the bay, a large amount of oxygen generated by photosynthesis will cause large reproduction of zooplankton such as copepods, cladocerans, and mysids in the bay, and Tokyo Bay will be reborn as a large fishing ground where sardines gather for them and tuna gather for sardines.

[0020] Thus, if the water depth is several tens of meters, even if the device is made, it is affordable and the effect can be trusted. Now, let's calculate the device with a water depth of 100 m. Assuming W0 = 8 m, M0 = 500 [m 3 / min], first estimate R0 using [Equation 1] so that the water depth becomes 100 m, assuming Δθ = 10 °C. TIFF2026050285000005.tif1770, so it can be estimated that R0 = 1.49 m. The power required to rotate three water scraping plates with W = 8 m and R0 = 1.49 m is calculated using [Equation 2] as "P0 = 307.2 [W]". Next, to narrow the flow that spreads with a width of W = 8 m to a width of 1 m, three water scraping plates with W = 1 m and R = 4.7 m are rotated, and the power required for this is calculated using [Equation 3] as "P = 2450 [W]". Therefore, with a solar panel of P0 + P = 307.2 [W] + 2457.6 [W] = 2765 [W], water can be pumped from the bottom of 101 m at a rate of 500 m per minute. 3The calculations suggest that by drawing up water, a device could be created to generate upwelling currents that would regenerate damaged areas of lakes, bays, and oceans into rich fishing grounds. The size of the device would also be such that it could be manufactured like a toy by China, which is focusing on developing marine ranches, or by shipbuilding companies. [Examples]

[0021] We are confident in the effectiveness of the invention at depths of several tens of meters, based on the results of demonstration experiments conducted in China, but at a depth of 100 meters from the seabed, at a rate of 500 meters per minute... 2 The practice of draining water from lakes, bays, and oceans to restore them into fertile fishing grounds has not yet been implemented.

[0022] This is currently on hold due to various issues, including the inability to obtain permission for installation sites, the lack of companies eager to develop large-scale upwelling generators, and other problems. However, ocean acidification is not man-made. It is a natural disaster caused by the Earth, and therefore its mitigation cannot be ignored. We expect that the development of a super-large upwelling generator that can enable mitigation will definitely be carried out. Potential for industrial use

[0023] Something terrible is happening right now. The ocean temperature has risen by 2°C. Seawater acidification is having a serious impact on fisheries. In Indonesia in particular, it is said that acidification caused by CO2 released from underwater volcanoes is causing a drastic decline in fish catches, which is becoming a major problem.

[0024] This is not limited to Indonesia. This ocean acidification is caused by the vaporization of CO2 contained in deep-sea water that has become hot due to anomalies in the ocean floor crust. The Japan Meteorological Agency and the Ministry of the Environment should understand that no matter how much humanity conserves coal, oil, and natural gas, it will not be able to prevent global warming or ocean acidification. Nevertheless, the United Nations, which has not been able to resolve the chaos of wars related to oil and natural gas, is further exacerbating the chaos by forcing CO2 reductions. Following the dictates of this dysfunctional UN, only the Japanese Prime Minister and the Governor of Tokyo have publicly declared that they will invest 2 trillion yen annually in CO2 reduction for 10 years, exposing Japan's ignorance to the world. This is more than just a disgrace. Wasting the hard-earned tax money of the people is a criminal act and cannot be tolerated. Despite this, such practices are rampant and have become commonplace around the world. What is needed now is to make the world aware of the current state of this global crisis through the development of upwelling current generators.

[0025] In recent years, about 300 years after the Industrial Revolution, the depletion of oil and natural gas and food shortages have become hot topics, and conflicts related to these issues continue unabated. However, it is also said that if coal becomes available, humanity could live without energy shortages for nine times the period of 300 years. What Japan must do now is not what humanity will do 2700 years from now when coal is depleted. It must eliminate 2 trillion yen in waste, and develop disaster-resilient land and cities in preparation for the unavoidable disasters triggered by rising ocean temperatures. It must also revitalize all industries that have been forced to shrink due to the reduction of electricity and thermal power.

[0026] What Japan must do now is use just a small portion of its 2 trillion yen budget to develop and provide to the world a super-large upwelling current generator that can mitigate ocean acidification, restore the oceans to abundant fishing grounds, and address the food problem caused by ocean acidification. It is abundantly clear that this invention will be utilized not only in Japan but in all industries around the world. [Brief explanation of the drawing]
