Description

Technical Field

[0001] The invention relates to the technical field of tidal energy power generation, and in particular to a self-cleaning tidal energy power generation device capable of preventing marine organisms from attaching. Background Art

[0002] As a clean and renewable energy source, the development and utilization of tidal energy is of great significance for reducing dependence on traditional fossil fuels and addressing climate change. However, existing tidal power generation devices face many challenges in practical applications, especially in terms of anti-marine biofouling and energy conversion efficiency. These problems not only affect the performance of the equipment, but also increase operating costs.

[0003] Existing tidal power generation devices usually convert mechanical energy into electrical energy by floating and swinging the buoy up and down. Although this design cleverly utilizes the natural movement of the tide, it will inevitably encounter the problem of marine organism attachment during long-term operation. The abundant microorganisms, algae, shellfish and other organisms 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 buoy, resulting in a decrease in its swing amplitude, which in turn affects the energy conversion efficiency. Due to the lack of an effective self-cleaning mechanism, current power generation devices are unable to remove these attachments by themselves, and usually require regular manual cleaning, which undoubtedly increases maintenance costs and workload. In addition, frequent manual intervention will increase the safety risks of operators and may cause equipment downtime to be extended, affecting the overall power generation efficiency.

[0004] In addition to marine biological attachment, the energy conversion efficiency of existing tidal power generation devices is also an urgent problem to be solved. Although the floating design can capture the mechanical energy of the tide, the loss in the energy conversion process is large and the maximum energy utilization is not fully realized. For example, when the tidal water flow is slow, the swing frequency and amplitude of the buoy will be affected, thereby reducing the power generation efficiency. Moreover, some devices adopt more complex mechanical structures in pursuit of high power output. Although this can increase the instantaneous power generation to a certain extent, it also increases the failure rate and maintenance difficulty, which is not conducive to long-term stable operation. To make matters worse, with the accumulation of marine biological attachments, the effective working area of ​​the equipment gradually decreases, further weakening the energy conversion efficiency.

[0005] Existing tidal power generation devices also show obvious shortcomings in coping with the complex and changeable marine environment. The marine environment is highly dynamic and unpredictable, and factors such as tidal cycles, water flow intensity and direction are constantly changing. However, the control strategies of most current power generation devices are 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, the attachment of marine organisms not only affects the physical properties of the equipment, but may also be the cause of accelerated corrosion in certain parts, which poses a threat to the durability and reliability of the equipment.

[0006] Therefore, how to provide a self-cleaning tidal energy power generation device that prevents marine organisms from attaching is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0046] The self-cleaning tidal energy power generation device for preventing marine organism attachment provided by the present invention has the following beneficial effects and advantages:

[0047] 1. Self-cleaning function: The cleaning component 2 can effectively remove marine organisms attached to the surface of the tidal buoy 4 through the coordinated action of the cleaning motor 2.1, the cleaning gear pair 2.2, the swing rod 2.3 and the scraper 2.4, so as to prevent the marine organisms from adhering to the surface of the equipment for a long time 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-efficiency energy conversion: The device uses a tidal power unit to convert the up and down movement of the tide into mechanical energy, and further enhances the energy conversion efficiency through a hydraulic system and a gear transmission system; the hydraulic system increases the driving force through the work of a curved pressure rod 5.1 and a curved piston 5.2, and effectively converts the kinetic energy of the tide into hydraulic power. The hydraulic push rod 5.6 pushes 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 tidal energy.

[0049] 3. Stable power output: Mechanical energy is further converted into electrical energy through the gear transmission system of the power assembly 7; the meshing 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 movement will not affect the stability of the system due to changes in direction; in particular, through the design of the one-way transmission part, it is ensured that the power generation gear 7.13 always rotates in a single direction, thereby avoiding the negative impact of reverse movement and ensuring the stability of power output.

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

[0051] 5. Modular design and easy maintenance: The design of the present invention fully considers the modular layout of each component, which is convenient for individual maintenance and replacement, and reduces the maintenance cost and operation complexity of the equipment in long-term use.

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

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

[0054] 1. Stable power generation output: Since the rotation direction of the generator gear 7.13 always remains consistent, the working mode of the generator 8 is stable, avoiding frequent direction reversal and current fluctuations; this stability can ensure that the output power of the generator 8 is more uniform and provide a more stable power supply.

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

[0056] 3. Reduce mechanical burden: The one-way drive system can reduce the pressure of reverse motion on the mechanical transmission system, reduce the possibility of equipment wear, and extend the service life of mechanical parts; this not only reduces maintenance costs, but also improves equipment reliability.

[0057] 4. Simplify transmission design: Through the one-way transmission system, the complexity of the gear transmission system can be simplified, and the number of transmission components that require precise adjustment can be reduced; such a design is simpler, more compact, easier 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 and ensure that the up and down movement of each tide can be effectively converted into mechanical energy and ultimately into electrical energy.

[0059] 6. Strong system adaptability: The one-way transmission system can maintain a consistent operating mode under different tidal conditions. No matter how the tidal fluctuations change, the system can always efficiently and stably convert mechanical energy into electrical energy to ensure efficient operation of the device.
