Description

Technical Field

[0001] The invention relates to marine garbage cleaning, and in particular to a marine garbage cleaning system based on water circulation power generation. Background Art

[0002] At present, the rapid development of the marine economy has continuously strengthened the development and utilization of marine resources. However, the marine garbage generated by human activities has posed a significant pollution challenge to the marine water environment. In order to effectively alleviate the increasingly serious trend of marine pollution, the marine garbage automatic cleaning system has been regarded as a key link in cleaning up marine garbage and has received much attention.

[0003] The automatic marine garbage cleaning system is a garbage cleaning system that can automatically clean the waters near the harbor around the clock. This system is not only convenient for cleaning marine garbage in the waters around the harbor, but also provides protection for marine pollution in terms of environmental protection and energy saving. The traditional garbage cleaning system cannot provide a strong endurance for the marine garbage cleaning system. At present, there are some "marine garbage bins" that use solar power generation equipment. Because they use solar energy, they not only have low power generation efficiency, but are also easily affected by the weather and environment, and cannot provide a stable supply of energy. In addition, the traditional manual operation method of salvaging marine garbage is not only inefficient, but also consumes a lot of time, manpower and material resources.

[0004] To this end, a marine garbage cleaning system based on water circulation power generation is designed. The self-circulating power generation equipment provides a stable energy supply for the garbage cleaning system, ensuring its strong endurance. At the same time, the automatic cleaning and processing of garbage is achieved by maintaining the all-weather operation of the self-priming pump. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a marine garbage cleaning system based on water cycle power generation, comprising a marine garbage cleaning platform, a water suction pump arranged on the upper part of the marine garbage cleaning platform, a power supply system and a power generation system connected to the water suction pump, and a marine garbage bin placed in the seawater, wherein the marine garbage bin is connected to the water suction pump through a water pipe; the water suction pump, the power supply system and the power generation system are all connected to an automatic control system controller;

[0006] The power generation system comprises an axial flow turbine generator connected to the water outlet of the water suction pump, and the water outlet end of the axial flow turbine generator is provided with a water outlet channel extending from the offshore garbage cleaning platform into the sea water;

[0007] The power supply system comprises a battery pack connected to a water suction pump, the axial flow turbine generator is connected to the water suction pump via a three-phase rectifier, and the battery pack is connected to the axial flow turbine generator via a contact regulator.

[0008] The present invention also discloses a method for implementing the same, comprising the following steps:

[0009] (1) The battery pack is started by the automatic control system controller, and the battery pack provides power to the water suction pump to start the water suction pump;

[0010] (2) After the water suction pump is started, on the one hand, the rotation of the water suction pump drives the axial flow turbine generator to rotate and generate electrical energy; at the same time, the electrical energy generated by the axial flow turbine generator is used to power the water suction pump through the three-phase rectifier;

[0011] (3) After the water suction pump is started, the suction force generated by the water suction pump will form a negative pressure in the marine garbage bin, causing the water in the ocean to enter the marine garbage bin together with the garbage. The garbage in the seawater is caught by the high-fiber filter net in the marine garbage bin and separated from the seawater. The seawater enters the water suction pump and the power generation system through the water suction pump to generate electricity;

[0012] (4) When the water suction pump starts to use the electricity provided by the generator, the automatic control system controller controls the contact regulator to automatically shut down the lithium battery pack to protect the battery and ensure efficient operation of the system.

[0013] The advantages of the present invention over the prior art are: the system forms a negative pressure in the marine garbage bin by setting a water suction pump, sucking garbage and water from the ocean into the garbage bin, and the water in the bin flows out along the drain outlet and enters the hydro-generator through the water pipe to generate electricity in a cycle, while the garbage in the bin is retained in the bin by the high-density fiber filter installed in the bin. The power supply system and power generation system of the system form a closed-loop energy circulation system, which is low in sensitivity to weather conditions, ensuring that the system can maintain a stable working state under any climatic conditions. In addition, the system significantly reduces dependence on external energy, thereby helping to reduce energy consumption and save economic costs, reflecting the dual considerations of environmental protection and economic benefits.

[0025] The power generation system 3 includes an axial-flow hydro-turbine generator connected to the water outlet of the water suction pump 2, and the water outlet end of the axial-flow hydro-turbine generator is provided with a water outlet channel 5 extending from the offshore garbage cleaning platform 1 into the sea water; the axial-flow hydro-turbine generator is a highly efficient hydroelectric power generation device, when the water flow impacts the turbine in the axial-flow hydro-turbine generator, its kinetic energy is converted into mechanical energy, driving the turbine to rotate; then, this rotational motion drives the generator in the axial-flow hydro-turbine generator to rotate, and the electromagnetic field inside the generator interacts with the rotating rotor, thereby generating electrical energy.

[0026] The water suction pump is a DC booster self-priming pump. The working principle of the DC booster self-priming pump is to use the negative pressure formed when the pump is working through DC power supply to pressurize the water below the water suction port under the action of atmospheric pressure, and then discharge it from the drainage end.

[0027] The power supply system includes a battery pack connected to the water suction pump 2, the axial flow turbine generator is connected to the water suction pump 2 through a three-phase rectifier, and the battery pack is connected to the axial flow turbine generator through a contact regulator. A three-phase rectifier is a device that converts AC power into DC power, and its main function is to convert an AC motor into a DC motor; in the power generation process of this system, the electric energy generated by the axial flow turbine generator is AC power, which is converted into DC power by a three-phase motor rectifier, and then the DC power energy is transmitted to the water pump for power supply.

[0028] The marine trash can 4 comprises a main barrel body 401, a seawater inlet 402 is arranged at the top of the main barrel body 401, a seawater outlet 403 connected to the water pipe 6 is arranged at the bottom, and a high-fiber filter net 404 covering the seawater inlet 402 is arranged inside the main barrel body 401; the marine trash can 4 is an inverted cone.

[0029] The implementation method of this system includes the following steps:

[0030] (1) The battery pack is started by the automatic control system controller, and the battery pack provides power to the water suction pump 2, so that the water suction pump 2 is started;

[0031] (2) After the water suction pump 2 is started, on the one hand, the rotation of the water suction pump 2 drives the axial flow turbine generator to rotate and generate electric energy; at the same time, the electric energy generated by the axial flow turbine generator is used to supply power to the water suction pump 2 through the three-phase rectifier;

[0032] (3) After the water suction pump 2 is started, the suction force generated by the water suction pump 2 will form a negative pressure in the marine garbage bin 4, so that the water in the ocean and the garbage enter the marine garbage bin 4 together, and the garbage in the seawater is caught by the high-fiber filter 404 in the marine garbage bin 4 and separated from the seawater. The seawater enters the water suction pump 2 and the power generation system 3 through the water suction pump 2 to generate electricity;

[0033] (4) When the water suction pump 2 starts to use the electric energy provided by the generator, the automatic control system controller controls the contact regulator to automatically shut down the lithium battery pack to protect the battery and ensure efficient operation of the system.

[0034] The power supply system of the marine garbage cleaning system of this embodiment is a self-circulating, green and efficient energy solution. The system starts the water suction pump through the battery pack to extract water, and the extracted water is then guided to the axial flow turbine generator through the water pipeline; in this process, the water flow drives the impeller in the turbine generator to rotate, thereby generating electricity; this power supply device constitutes a closed-loop energy circulation system, which realizes the automated cleaning of marine garbage, effectively solves the energy supply problem in the cleaning operation, and significantly improves the operating stability of the system; at the same time, it greatly reduces the consumption of non-renewable resources and saves manpower, financial resources and energy costs.

[0035] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
