The present invention discloses methods and apparatus for converting water wave energy into electricity on a utility scale. The device comprises: (1) an oscillating body that effectively responds to waves in all six degrees of freedom: surge, sway, heave, roll, pitch, and yaw, (2) a restraining system to prevent the oscillating body from being displaced by steady environmental loads, and (3) a power takeoff system comprising linear generators which are directly driven by the oscillating body to generate electricity. The devised devices excel in harnessing wave energy across a wide spectrum of frequencies and are well-suited for deployment in both shallow and deep ocean waters.

To provide the construction and a method of a natural farm that gives no stress to an aquatic organism, causes no risk of disturbing an environment due to escape, is safe, and has low costs by installing an escape and hiding place of a juvenile fish, protecting the juvenile fish, improving a survival rate of the juvenile fish, culturing the juvenile fish by natural predation of an organism, employing water quality with natural purification action, and culturing the juvenile fish in the same ecosystem as that in the ambient, and to create a rich fishing place in a coast by discharging deep ocean water onto a front layer of a sea level having poor nutrition.SOLUTION: Proliferation is achieved by protecting a juvenile fish by providing: a surrounding part provided in a land side water area of an offshore breakwater block, having no bottom surface, having a lower end edge portion always contacting a water bottom, and having an upper end edge portion always being over the water level; and a hiding place for a juvenile fish that has entered the place through a clearance part, that is provided in the surrounding part, and to and from which a juvenile fish can enter and exit and an adult fish cannot enter and exit, and by fertilizing the periphery of the surrounding part by a deep water upwelling device.SELECTED DRAWING: Figure 1

The invention discloses an ocean deep water quality evaluation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring ocean deep water data through a preset ocean deep water survey station; extracting test data of the deep ocean water based on the deep ocean water data; constructing evaluation indexes of multiple evaluation aspects of the deep ocean water based on the basic characters of the deep ocean water resources; substituting the test data into the evaluation index to obtain the index score of the single index of each characteristic of the deep ocean water; and in response to the target purpose of the deep ocean water, obtaining a water quality evaluation result based on the index score of the at least one single index. According to the method, comprehensive evaluation can be carried out by selectively combining the scores of the related single indexes according to the specific target purpose of the deep ocean water, so that the evaluation result highly conforms to the actual application requirement, and the water quality evaluation of the deep ocean water can be accurately carried out.

This invention belongs to the field of cosmetic technology, specifically disclosing a deep-sea water mineral powder, its preparation method, and its application. The preparation method includes the following steps: vacuum evaporation and concentration of deep-sea water to obtain a concentrated solution; adding NaOH solution dropwise while stirring to adjust the pH, continuing stirring, centrifuging, discarding the precipitate, and obtaining the reactant; adjusting the pH to acidic, stirring at a certain speed, adding tannic acid solution dropwise, gradient heating, and allowing to stand for aging to obtain the reaction mixture; centrifuging to separate the precipitate, washing, and obtaining a wet filter cake; vacuum drying, pulverizing, and sieving to obtain the deep-sea water mineral powder. This deep-sea water mineral powder exhibits excellent water-holding capacity and oil-controlling properties, as well as excellent antioxidant activity, showing promising application prospects as a cosmetic raw material.

The present invention relates to the field of marine science and energy technology, and discloses a deep-sea water lifting device utilizing wave energy. The deep-sea water lifting device utilizing wave energy comprises a barrel, a float, a one-way valve and a counterweight mechanism. The barrel is provided with a water channel that runs up and down along the axial direction. The float is arranged on the outer wall of the upper part of the barrel. The one-way valve is arranged at the bottom opening of the water channel. The counterweight mechanism comprises a connecting assembly and a counterweight block, the barrel is rotatably connected to the first end of the connecting assembly, and the counterweight block is connected to the second end of the connecting assembly. The deep-sea water lifting device utilizing wave energy provided by the present invention can lift the bottom water of the ocean to the surface with the help of the action of waves, without the need for additional energy supply, and no personnel need to be sent to guard after being arranged on the seabed, and can be arranged in offshore waters with poor sea conditions.

The invention provides a method for producing an enhanced foliar fertilizer by using a deep sea water concentrated solution instead of a hydrosolvent, the deep sea water concentrated solution is produced more efficiently and at lower cost by adopting a magnetofluid seawater desalination separation method, and the concentrated solution produced by the method, an electrodeionization method and other methods is used as a solvent. The traditional water solvent for producing foliar fertilizers and nutrient solutions is replaced, various water-soluble enhanced foliar fertilizers and plant nutrient solutions are produced on the premise of not changing the existing equipment and process, various mineral substances and trace elements can be supplemented, the absorption rate of crops to the mineral substances and the trace elements is improved, and the water-soluble enhanced foliar fertilizers and plant nutrient solutions are obtained. The disease resistance, stress resistance, immunocompetence and growth ability of plants can be enhanced, the yield and quality of crops are improved, the usage amount of chemical fertilizers and pesticides is reduced, pollution and damage to the environment are reduced, and development of deep sea resources and green functional agriculture is greatly promoted.
