Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tidal energy power generation, and particularly relates to a self-cleaning tidal energy power generation device capable of preventing marine biofouling. BACKGROUND

[0002] Tidal energy, as a clean and renewable energy source, has great significance in reducing dependence on traditional fossil fuels and addressing climate change. However, existing tidal energy power generation devices face many challenges in practical application, particularly in preventing marine biofouling and improving energy conversion efficiency. These problems not only affect the performance of the equipment, but also increase operating costs.

[0003] Existing tidal energy power generation devices typically convert mechanical energy into electrical energy through the up-and-down floating swing of a float. Although this design ingeniously utilizes the natural movement of tides, it inevitably encounters the problem of marine biofouling during long-term operation. Microorganisms, algae, and shellfish in the marine environment easily form a thick layer of attachments on the surface of the equipment. These attachments not only increase the weight of the structure, but also change the fluid dynamics of the float, resulting in a decrease in swing amplitude and affecting energy conversion efficiency. Due to the lack of effective self-cleaning mechanisms, current power generation devices cannot remove these attachments on their own, and usually require regular manual cleaning, which undoubtedly increases maintenance costs and workload. In addition, frequent manual intervention also increases the safety risk of operators and may cause extended equipment downtime, affecting overall power generation efficiency.

[0004] In addition to marine biofouling, the energy conversion efficiency of existing tidal energy power generation devices is also a problem that needs to be solved. Although the floating design can capture the mechanical energy of tides, there is a significant loss in the energy conversion process, which fails to fully maximize energy utilization. For example, when the tidal water flow speed is slow, the swing frequency and amplitude of the float are affected, reducing power generation efficiency. Moreover, some devices use more complex mechanical structures to pursue high power output, which can increase instantaneous power generation to some extent, but also increases the failure rate and maintenance difficulty, which is not conducive to long-term stable operation. Worse still, as marine biofouling accumulates, the effective working area of the equipment gradually decreases, further weakening energy conversion efficiency.

[0005] In response to the complex and changeable marine environment, the existing tidal power generation devices also show obvious shortcomings. The marine environment has high dynamicity and unpredictability, and factors such as tidal period, flow intensity and direction are constantly changing. However, the control strategy of most current power generation devices is relatively simple, and it is difficult to respond quickly according to real-time conditions. This static or semi-static operating mode cannot fully utilize the energy brought by each tide, especially when the tidal flow rate is low or the direction changes, the power generation efficiency will be significantly reduced. In addition, marine organisms not only affect the physical performance of the equipment, but also may become the cause of accelerated corrosion in some parts, which threatens the durability and reliability of the equipment

[0006] Therefore, how to provide a self-cleaning tidal power generation device that prevents marine organisms from attaching is a problem that those skilled in the art need to solve. SUMMARY

This avoids the long-term attachment of marine organisms on the surface of the equipment, which affects the normal operation of the equipment. The implementation of the self-cleaning function reduces the need for manual cleaning and maintenance costs, and improves the long-term stability of the equipment. By providing a cold end plate and a hot end plate on the tidal buoy, an additional power supply is provided by the temperature difference power generation system of seawater and sunlight. The temperature difference between the cold end plate and the hot end plate is converted into electrical energy by a thermoelectric module, further improving the energy self-sufficiency of the equipment. The generated electrical energy is stored in the battery column for use by the cleaning motor, ensuring long-term operation of the cleaning system.

[0046] The self-cleaning tidal energy power generation device provided by the application has the following advantages and benefits:

[0047] 1. Self-cleaning function: the cleaning assembly 2 can effectively remove the marine organisms attached to the surface of the tidal buoy 4 through the cooperative action of the cleaning motor 2.1, the cleaning gear pair 2.2, the swing rod 2.3 and the scraper 2.4, thereby avoiding the long-term attachment of marine organisms on the surface of the equipment and affecting the normal operation of the equipment; the realization of the self-cleaning function reduces the need for manual cleaning and maintenance costs and improves the long-term stability of the equipment.

[0048] 2. High energy conversion efficiency: the device converts the up-and-down movement of the tide into mechanical energy through the tidal power unit, and further enhances the energy conversion efficiency through the hydraulic system and the gear transmission system; the hydraulic system increases the driving force through the work of the curved pressure rod 5.1 and the curved piston 5.2, effectively converts the kinetic energy of the tide into hydraulic power, and the hydraulic push rod 5.6 drives the displacement tooth plate 5.7 to move, thereby driving the operation of the power assembly 7; the energy conversion chain of the system is reasonable and effective, and can maximize the utilization of tidal energy.

[0049] 3. Stable power output: The mechanical energy is further converted into electrical energy through the gear transmission system of the power assembly 7. The engagement between the extended power main gear 7.1 and the retracted power main gear 7.14 and the displacement gear plate 5.7 ensures that the conversion of tidal up and down movements does not affect the stability of the system due to changes in direction. Especially through the design of one-way transmission, it ensures that the power generation gear 7.13 always rotates in a single direction, thereby avoiding the negative effects of reverse motion and ensuring the stability of the power output.

[0050] 4. Thermoelectric power enhancement system: By setting the cold end plate 2.5 and the hot end plate 2.6 on the tidal float 4, the thermoelectric power system using the temperature difference between seawater and sunlight provides additional electrical energy. The temperature difference between the cold end plate 2.5 and the hot end plate 2.6 is converted into electrical energy by the thermoelectric module 2.7, further improving the energy self-sufficiency of the device. The battery column 2.8 stores the generated electrical energy for the use of the cleaning motor 2.1, ensuring the long-term operation of the cleaning system.

[0051] 5. Modular design, easy to maintain: The design of the invention fully considers the modular layout of each component, which is easy to maintain and replace, reducing the maintenance cost and operation complexity of the device during long-term use.

[0052] 6. Environmental protection and energy saving: Tidal energy is a renewable energy source. This device efficiently utilizes tidal energy, reduces dependence on traditional fossil fuels, helps reduce carbon emissions, and promotes sustainable development. At the same time, the self-cleaning function of the marine ecosystem helps protect marine biodiversity and meets environmental protection requirements.

[0053] The power generation gear 7.13 always rotates in a single direction, thereby avoiding the negative effects of reverse motion and ensuring the stability of the power output, as follows:

[0054] 1. Stable power generation output: Since the rotation direction of the power generation gear 7.13 always remains consistent, the working mode of the generator 8 is stable, avoiding frequent direction reversal and current fluctuation. This stability ensures that the output power of the generator 8 is more uniform, providing more stable electrical energy supply.

[0055] 2. Improve efficiency: By delivering power to the generator 8 in one direction, any possible energy loss or unnecessary reverse motion is avoided. Each rise and fall of the tide can maximize the use of mechanical energy for power generation, reducing energy waste and improving the overall energy efficiency of the system.

[0056] 3. Reduce mechanical burden: The one-way drive system can reduce the pressure on the mechanical transmission system caused by reverse motion, reducing the possibility of equipment wear and tear and prolonging the service life of mechanical components. This not only reduces maintenance costs but also improves the reliability of the equipment.

[0057] 4. Simplified transmission design: With the one-way transmission system, the complexity of the gear transmission system can be simplified, reducing the need for precise adjustment of transmission components; such design is more simple, compact, easy to manufacture and maintain.

[0058] 5. Efficient tidal energy utilization: Tidal energy is a natural resource with periodicity and directionality. Through this one-way transmission design, it can better adapt to the characteristics of tides, ensuring that each tidal movement can be effectively converted into mechanical energy and ultimately into electrical energy.

[0059] 6. Strong system adaptability: The one-way transmission system can maintain consistent operation mode under different tidal conditions. Regardless of the change in tidal range, the system can always efficiently and stably convert mechanical energy into electrical energy, ensuring efficient operation of the device.
