[0061] In a specific embodiment, the renewable power system 2 includes a photovoltaic component 21 for converting solar energy into electric energy, an energy storage device 22 for storing the electric energy converted by the photovoltaic component, and a spark gap switch 23 for controlling the first electrode 423 and the second electrode 424 to release a pulse electric field, which are connected in sequence; and the energy storage device 22 is specifically an energy storage capacitor and its size is 20 to 120 μF;

[0062] A transformer is also provided between the energy storage device 22 and the spark gap switch 23;

[0063] The transformer is used to adjust the voltage output from the energy storage device 22 so as to transmit it to the first electrode 423 and the second electrode 424 through the spark gap switch 23; preferably, the electrode material of the first electrode 423 and the second electrode 424 is a metal corrosion-resistant material, such as a tungsten-copper alloy; the electrode spacing is 2 to 15 mm; the electrode spacing is the distance between the top of the first electrode 423 and the bottom of the second electrode 424; the curvature radius of the electrode tip of the second electrode 424 is 0.5 to 5 mm.

[0068] The inner wall of the hollow cavity structure is provided with a catalytic functional coating for obtaining free radicals under strong photocatalysis to promote the generation of strong oxidizing substances;

[0069] In this embodiment, after the curved cavity structure 41 is filled with water, the spark gap switch 23 is turned on, the voltage is adjusted to 10-30 kV through the transformer, and the release period is 1-30 s / time.

In this process, multiple physical and chemical effects (pulsed electric field, strong light, strong oxidizing active substances, pressure waves) are simultaneously generated. The inner wall of the water tank is coated with a catalytic functional coating. Due to the photocatalytic effect, more free radicals are stimulated, thereby increasing the generation of strong oxidizing active substances, thereby oxidizing and damaging the algae cell structure, and achieving efficient inactivation of algae; the pressure wave is enhanced due to the energy reflection of the inner wall of the curved cavity structure 41, and is emitted from the pressure wave emission port 411 to the designated fish school.

[0072] In a specific embodiment, Figure 4 As shown, it includes an electrode driving device 421 for adjusting the electrode spacing, which includes an air compressor 4211 and a compression cylinder 4212;

[0075] The first electrode 423 and the second electrode 424 are respectively disposed at two ends of the insulating member 422;

[0076] The top of the insulating member 422 is provided with an annular structure 4221, and the top of the annular structure 4221 is fixed to the inner wall of the top of the curved cavity structure 41, and the inner diameter of the annular structure 4221 is the same as the diameter of the mounting hole structure 413;

[0077] The compression cylinder 4212 is fixedly connected to the outer wall of the hollow cavity structure through the mounting hole structure 413, and the output end of the piston rod of the compression cylinder 4212 is connected to one end of the second electrode 424;

[0078] The other end of the second electrode 424 passes through the annular structure 4221 and is movably connected to the annular structure 4221;

[0079] The air compressor 4211 can drive the piston rod of the compression cylinder 4212 to move back and forth through a pipeline, thereby driving the second electrode 424 and the annular structure 4221 to move relative to each other.

[0080] In this embodiment, the initial distance of the electrode spacing is set and recorded, and the electrode spacing control module controls the air compressor 4211 to drive the piston rod of the compression cylinder 4212 to reciprocate through the gas in the air pipe, and then the movement distance of the piston rod is measured by existing equipment (such as by installing a displacement sensor on the compression cylinder 4212) to adjust the electrode spacing. The compression cylinder 4212 is made of insulating material such as plastic.

[0081] In a specific embodiment, it also includes one or more speakers 44 which are arranged outside the curved cavity structure 41 and connected to the inner wall of the curved cavity structure 41 and are adjacent to the pressure wave emission port 411 .

[0082] In a specific embodiment, the curved cavity structure 41 is specifically an elliptical hollow cavity structure.

[0083] In a specific embodiment, the material of the catalytic functional coating includes at least any one of Ag-modified TiO2, Ni-Cu-modified TiO2, non-metal-modified TiO2, non-metal-modified g-C3N4, Mo-Cu-modified g-C3N4 or Ni-Ag-modified g-C3N4.

[0084] A multi-effect coupling method for removing algae and driving fish driven by renewable electric energy, such as Figure 1 As shown, the following steps are included:

[0085] S1: Control the main body driving device 412 through the mobile control module to realize the multi-effect coupling algae removal and fish driving device 4 to move underwater;

[0086] S2: setting a preset sampling period, and controlling the underwater monitoring device 43 through the underwater monitoring control module, periodically collecting underwater image data during the movement of the multi-effect coupling algae removal and fish driving device 4, and obtaining fish school / algae data in the underwater image data based on the existing image recognition technology;

[0087] The underwater monitoring device 43 includes an underwater camera, an underwater lighting lamp and an underwater sonar device; the fish school / algae data at least includes the type of fish school / algae and the number and position of fish school / algae;

[0088] In order to avoid that the collected underwater image data cannot clearly and accurately identify the fish / algae through the image recognition technology, the method also includes data processing of the periodically collected underwater image data: that is, the underwater image is preliminarily processed by the Gaussian filtering algorithm to blur the high-frequency noise in the underwater image; the guided filtering algorithm is used to perform secondary processing on the low-frequency noise in the underwater image after the Gaussian filtering; the results of the Gaussian filtering and the guided filtering are synthesized to form a bilateral filter, and the noise of the underwater image after the guided filtering is processed by the bilateral filter; the bilateral filtering result is obtained, and a pixel-level analysis is performed to determine whether there is a color deviation; if the pixel-level analysis determines that there is a color deviation, the image parameters are dynamically adjusted by the white balance correction algorithm to generate underwater image data after white balance correction, and then the category of the fish / algae in the underwater image data is obtained according to the image recognition technology, and obtaining the category of the fish / algae in the underwater image data by the image recognition technology is an existing well-known technical means, which will not be repeated here;

[0089] The method for obtaining the number of fish / algae is as follows:

[0090] The underwater sonar equipment is used to collect sonar images within a preset distance range under the water surface. The principle of sonar imaging is to use ultrasonic waves to send out signals, which are reflected back after hitting a moving underwater object. The underwater fish / algae are identified by calculating the time, direction and strength of the signal response.

[0091] A preprocessed image after each sonar image is processed is obtained through image preprocessing, and the image preprocessing includes linear stretching, median filtering and sharpening processing; the area to be divided of the target fish in the preprocessed image is extracted through edge detection technology; a binary division threshold for acoustic calibration of the target fish is set based on an image binarization division threshold algorithm, and the area to be divided is binarized according to the binary division threshold, and the target fish in the binarized image is extracted; the number of fish schools / algae is obtained according to the number of target fish in each sonar image;

[0092] S3: Based on the fish / algae data, the electrode distance control module controls the electrode driving device 421 to adjust the electrode distance, and adjusts the voltage output from the energy storage device 22 according to the transformer 24 to transmit to the first electrode 423 and the second electrode 424 through the spark gap switch 23;

[0093] Specifically, the corresponding fish / algae data is obtained according to a preset sampling period, that is, the electrode spacing and impulse voltage that can achieve the removal effect under the corresponding conditions are set according to the number of fish / algae, and then the electrode spacing sequence table and impulse voltage sequence table corresponding to different numbers of fish / algae are obtained;

[0094] The electrode spacing sequence table and the impulse voltage sequence table are a descending order table of the distances between the first electrode 423 and the second electrode 424 corresponding to the generation of multiple physical and chemical effects of different intensities, and an impulse voltage sequence table corresponding to the descending order table;

[0095] For example, when there are many fish, the electrode spacing can be reduced and the impulse voltage can be increased to generate stronger light, pressure waves and sound waves, as well as more strong oxidizing substances to achieve the effect of driving fish and removing algae; when there are few fish, the electrode spacing can be increased and the impulse voltage can be reduced to generate smaller light, pressure waves and sound waves, as well as less strong oxidizing substances to achieve the effect of driving fish and removing algae, which can effectively reduce energy consumption and energy utilization.

[0096] S4: releasing a pulse electric field in the water through the first electrode 423 and the second electrode 424 to produce a variety of products capable of removing algae and repelling fish under multiple physical and chemical effects;

[0097] The products include strong light, strong oxidizing substances, pressure waves and sound waves;

[0098] The strong oxidizing substances at least include hydrogen peroxide, ozone and active free radicals;

[0099] S5: Obtain free radicals through the catalytic functional coating under strong photocatalysis to promote the generation of strong oxidizing substances;

[0100] and damage algae cells through oxidation by strong oxidizing substances;

[0101] The pressure wave is reflected and enhanced by the inner wall of the curved cavity structure 41;

[0102] The generated sound waves are amplified by the speaker 44;

[0103] The amplified sound waves, the reflected and enhanced pressure waves released through the pressure wave emission port 411, and the generated strong light can be used to achieve directional driving of the school of fish.

[0104] This embodiment provides a device and method for multi-effect coupling algae removal and fish driving driven by renewable electric energy.

Its advantages include: first, the device of the present invention uses solar energy to generate electricity, which is energy-saving and environmentally friendly; second, the system has high processing efficiency and high degree of automation, and the equipment is simple and easy to operate; third, the device is driven by renewable electric energy to induce multiple physical and chemical effects (pulsed electric field, strong light, strong oxidizing active substances, pressure waves) underwater to effectively remove algae blooms and achieve large-scale fish driving to prevent them from eating aquatic plants; fourth, the device does not need to add chemical agents and will not cause secondary pollution to the water body; it is precisely because of the above advantages that the device can quickly and efficiently achieve the effect of algae removal and fish driving.
