Description

Technical Field

[0001] The present invention relates to the technical field of marine renewable energy and biological resources, and in particular to an integrated marine wind power-microalgae cultivation combined device and method. Background Art

[0002] As a clean and renewable energy technology, wind power generation has been widely used around the world. It uses natural wind energy and converts it into electrical energy through wind turbines to provide power support for human society. With the continuous growth of global energy demand and the increasing awareness of environmental protection, wind power generation, as a low-carbon and environmentally friendly energy form, has become increasingly important.

[0003] The traditional form of wind power generation is onshore wind power generation. However, traditional onshore wind power generation facilities often occupy a large amount of land resources, especially those high-quality agricultural lands located in areas suitable for wind power generation. This occupation not only limits the space for agricultural production, but also intensifies the competition for agricultural resources, which has an adverse impact on traditional agriculture.

[0004] Secondly, as an efficient and sustainable way to develop biological resources, the development of microalgae farming itself is also limited by land resources. The growth of microalgae requires light, water and a suitable nutritional environment, and these conditions often overlap with the resources required for agricultural production. Microalgae farming around traditional land-based wind power facilities may further intensify competition for land resources, which is not conducive to the coordinated development of agriculture and biological resource development.

[0005] In addition, traditional onshore wind power generation facilities may generate certain noise and visual pollution during operation, causing interference to the surrounding environment and residents' lives. Microalgae farming requires a relatively quiet and pollution-free growth environment to ensure the healthy growth and high-quality output of microalgae. Therefore, the combination of traditional onshore wind power generation and microalgae farming also has certain challenges in terms of environmental compatibility. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides an integrated marine wind power-microalgae cultivation combined device, which combines a vertical axis wind turbine for wind power generation, effectively utilizing the abundant wind energy resources in the ocean. At the same time, the electricity generated by power generation is used for microalgae cultivation, which realizes the multi-level utilization of energy and improves the efficiency of resource utilization. Microalgae cultivation, as a bioenergy production method, has lower carbon emissions and environmental pollution compared to traditional fossil energy. By cultivating microalgae in the marine environment, a large amount of carbon dioxide can also be absorbed, which helps to alleviate the problem of ocean acidification and promote the balance of marine ecology. Vertical axis wind turbine power generation can provide a stable source of electricity for microalgae cultivation and reduce the cost of cultivation.

[0017] Furthermore, each blade is connected to the side plate of the tower through a connecting rod, ensuring the stability and reliability of the blade during rotation, thereby improving the efficiency of wind power generation. The tower is the main supporting structure of the wind drive unit, and its bottom is vertically driven on the power generation unit, making the entire structure more stable and able to withstand greater wind force and torque.

[0018] Furthermore, the rotating shaft, as a connecting component between the wind drive unit and the power generation unit, can effectively convert the wind energy captured by the blades into mechanical energy and transmit it to the power generation unit for electrical energy conversion.

[0019] Furthermore, as the core part of the power generation unit, the cabin is equipped with a motor inside, which can efficiently receive the mechanical energy transmitted from the tower and blades and convert it into electrical energy. The bottom of the tower is directly connected to the motor through the cabin via the rotating shaft, which reduces the intermediate links of energy transmission, reduces energy loss, and improves energy conversion efficiency. The first power control module and the second power control module are respectively connected to the motor, which can accurately control the distribution and transmission of electrical energy to ensure stable power supply to the microalgae cultivation unit and the light source unit.

[0020] Furthermore, the U-shaped box design maximizes the use of the internal space. The power generation unit is located in the center of the box, and the microalgae cultivation unit surrounds it. This layout is compact and efficient, reducing space waste. The surrounding microalgae cultivation units can make full use of the lighting conditions at the edge of the box, while avoiding the problem of insufficient light in the center area due to shading. Furthermore, two groups of microalgae cultivation tubes are arranged around the U-shaped structure of the box, making full use of the space, while ensuring that the microalgae grow under sufficient light and suitable cultivation conditions, which helps to increase the cultivation density and yield of microalgae. The setting of the air supply interface and the material delivery interface allows the microalgae cultivation tube to easily replenish gas and transport materials. Air supply helps microalgae to photosynthesize and increase the growth rate; material delivery can achieve regular harvesting and nutrient supplementation of microalgae to maintain the stability of the cultivation environment. The setting of the gas distribution valve and the diverter valve can accurately control the delivery volume of gas and materials to avoid waste and over-supply. The delivery pump ensures the stable delivery of gas and materials in the microalgae cultivation tube. The first control module realizes remote monitoring and intelligent control of the entire microalgae cultivation unit by connecting the gas distribution valve, the diverter valve and the delivery pump. This can not only improve the cultivation efficiency, but also reduce labor costs.

[0021] Furthermore, the light source unit uses a plurality of LED light source boards distributed at the bottom of the microalgae breeding unit, which can realize accurate supplementary light for the microalgae breeding unit. The LED light source has the advantages of high efficiency, energy saving, long life, etc., and the spectrum is adjustable, which can provide suitable lighting conditions according to the growth requirements of microalgae. Through accurate supplementary light, the photosynthesis efficiency of microalgae can be improved, and the rapid growth and reproduction of microalgae can be promoted, thereby improving the yield and quality of microalgae. As the control center of the light source unit, the second control module can intelligently adjust the brightness and working time of the LED light source board according to the sunlight intensity monitored by the irradiance sensor. When the sunlight is sufficient, the supplementary light intensity of the LED light source board is reduced; when the sunlight is insufficient, the supplementary light intensity is increased to ensure that the microalgae breeding unit obtains suitable lighting conditions. As a backup power supply for the light source unit, the second energy storage battery can provide a stable power supply for the LED light source board when the power generation unit fails or the power is insufficient. This ensures that the microalgae breeding unit can obtain sufficient lighting conditions under any circumstances, ensuring the continuous operation of the system and the normal growth of microalgae. The irradiance sensor is arranged on the pipeline fixing frame, which can monitor the sunlight intensity in real time and feed the monitoring data back to the second control module. This helps to promptly detect and resolve insufficient or excessive lighting issues, improving system reliability and stability.

[0022] Furthermore, a boarding ladder is provided between the power generation unit and the box body, which provides a convenient passage for the staff, so that they can easily reach the power generation unit for daily maintenance, inspection and troubleshooting, improve the reliability and stability of the equipment, and reduce the downtime caused by equipment failure. The present invention also provides an integrated marine wind power-microalgae cultivation method, which combines marine wind power with microalgae cultivation to achieve efficient integration and utilization of marine resources. The wind drive unit uses the sea wind to drive the power generation unit to generate electricity, which not only reduces the dependence on traditional energy, but also makes full use of the renewable energy of the ocean. At the same time, the microalgae cultivation unit uses this electricity to cultivate microalgae, forming a circular utilization of resources. Providing electricity for microalgae cultivation through wind power generation avoids the use of traditional energy, reduces energy consumption and carbon emissions. In addition, the method also accurately manages the electricity in the microalgae cultivation process through an intelligent control module, thereby improving the efficiency of energy utilization.

[0023] Furthermore, the transparent glass material can allow sunlight to penetrate and shine into the microalgae cultivation unit, providing sufficient lighting conditions for the microalgae. BRIEF DESCRIPTION OF THE DRAWINGS
