技术领域technical field
本实用新型属于新能源利用技术领域，涉及一种导管架海洋平台集成波能发电装置。The utility model belongs to the technical field of new energy utilization, and relates to a jacket ocean platform integrated wave energy generating device.
背景技术Background technique
一方面，随着全球能源消耗量日益增加，传统的不可再生能源逐渐减少，能源问题越来越突出。绿色可再生能源得到人类的广泛关注。其中波浪能开发对环境的影响小且以机械能的形式存在，是可再生能源开发的热点。另一方面，目前国内外的许多边际油田面临生产效益低下的问题。这些油田位于近海区域，储油量少，故采油设施的运行和维护比较简单，通常是无人值守的，而且不能通过像大型油田那样直接燃烧开采的石油来提供生产生活用电。因此，这一类的小型石油开采设施的用电问题可以通过波浪能发电来解决。On the one hand, with the increasing global energy consumption and the gradual reduction of traditional non-renewable energy sources, energy problems are becoming more and more prominent. Green and renewable energy has been widely concerned by human beings. Among them, the development of wave energy has little impact on the environment and exists in the form of mechanical energy, which is a hot spot in the development of renewable energy. On the other hand, many marginal oil fields at home and abroad are facing the problem of low production efficiency. These oilfields are located in the offshore area and have little oil storage. Therefore, the operation and maintenance of oil extraction facilities are relatively simple, and they are usually unattended, and they cannot provide electricity for production and living by directly burning the extracted oil like large oilfields. Therefore, the power consumption problem of such small-scale oil extraction facilities can be solved through wave energy generation.
导管架海洋平台集成波能发电装置最主要的部分是振荡水柱式波能转换装置，该装置主要有固定式和浮式两种，其主体结构是一个向下开口的气室结构，上部有气孔管道连接空气透平装置。而目前已有的固定式结构，都只有一侧面向来浪方向，不能同时对不同方向来浪进行有效吸收；浮式结构一般采用锚链结构固定，其成本高、可靠性低且波能转换率较低。因此，提高波浪能利用率、降低波能发电成本，始终是波能利用研究的关键。导管架海洋平台集成波能发电装置可以接收各个方向的来浪，不仅提高了波能利用率，而且使固定式的振荡水柱波浪能发电装置从近岸走向离岸成为可能，为海洋的平台正常运行提供了电能。The most important part of the integrated wave energy power generation device on the jacket offshore platform is the oscillating water column wave energy conversion device. There are mainly two types of this device: fixed type and floating type. Pipes connect to the air turbine unit. At present, the existing fixed structures have only one side facing the direction of incoming waves, and cannot effectively absorb incoming waves from different directions at the same time; floating structures are generally fixed by anchor chain structures, which have high cost, low reliability and low wave energy conversion efficiency. lower. Therefore, improving the utilization rate of wave energy and reducing the cost of wave energy generation are always the key to the research of wave energy utilization. The integrated wave energy generation device of the jacket offshore platform can receive incoming waves from all directions, which not only improves the utilization rate of wave energy, but also makes it possible for the fixed oscillating water column wave energy generation device to move from the near shore to the offshore, which is a normal Power is provided for operation.

The top of the gas chamber 2 adopts a hemispherical ring body 3, and the gas enters the air hole pipe 5 through the hemispherical ring body 3, which can effectively reduce resistance, increase air velocity, and improve power generation efficiency.
所述的海洋平台桩基结构7为圆柱型钢管桩，水柱上下振动时能有效减少阻力，提高发电效率。海洋平台桩基结构7设置在圆柱环体1中轴线上，能有效减少气室内部水面晃荡。The offshore platform pile foundation structure 7 is a cylindrical steel pipe pile, which can effectively reduce resistance and improve power generation efficiency when the water column vibrates up and down. The pile foundation structure 7 of the offshore platform is arranged on the central axis of the cylindrical ring body 1, which can effectively reduce the sloshing of the water surface inside the gas chamber.
所述的气室2内水柱有一个固定的波动频率，选择合适的气室2尺寸可以使得气室内水面振荡频率与外面波浪频率相近，共振的水面波动幅度会远高于波浪的幅度，大大提高气体的流速和流量，从而提高系统效率。The water column in the air chamber 2 has a fixed fluctuation frequency. Choosing a suitable size of the air chamber 2 can make the water surface oscillation frequency in the air chamber similar to the frequency of the waves outside, and the resonant water surface fluctuation amplitude will be much higher than the wave amplitude, greatly improving The flow rate and flow rate of the gas, thus improving the system efficiency.
