Background technique

As land-based resources are difficult to meet the needs of the development of human society, countries all over the world regard marine renewable energy as a strategic resource to solve energy shortages and address climate change. Especially in the 21st century, facing the increasing scarcity of fossil energy such as coal and oil and the enormous pressure of reducing environmental pollution and coping with climate change, the international community has reached a consensus on the strategic position of marine renewable energy in the future energy field. Development and utilization has become one of the important contents of global high-tech in the 21st century.

As a clean and renewable energy source, wave energy has been studied by humans as early as a century ago, but the wave energy research at that time was mainly focused on the invention of wave energy conversion devices, and the truly practical wave energy devices rare. It was not until the mid-1970s that people began to seriously study the actual utilization technology of wave energy. After long-term research, developed countries such as the United States, Denmark, the United Kingdom, and Japan have developed rapidly in wave energy research technology, made breakthroughs, and carried out large-scale application demonstration tests. China is also one of the major wave energy research and development countries in the world. Since the early 1980s, researches have been mainly carried out on fixed and floating oscillating water column wave energy devices and pendulum wave energy devices.

Although wave energy absorbing devices have developed to a certain extent, compared with other forms of energy utilization devices, such as wind energy, they are still in an immature state. At present, the following modes are generally adopted by wave energy generating devices: 1. Convert wave energy into hydraulic energy, and promote the rotation of a turbine connected to the generator, so that the generator rotates to generate electricity. The design of the wave energy generating device with this structure is relatively complicated, and the cost is high and the maintenance cost is high. 2. Convert wave energy into mechanical energy and directly drive the generator to generate electricity. Theoretically speaking, this method has fewer stages of capacity conversion and avoids energy loss in the process of multi-stage conversion, but its reliability in dealing with extreme weather conditions is poor. 3. To convert wave energy into flowing compressed air, and then generate electricity, the main method is to add a space structure connected to seawater in the breakwater. With the surge of waves, the water level rises and falls, and then drives the generator impeller to rotate, and finally drives Generators generate electricity. During use, the amplitude of water level is low, and the efficiency of energy absorption is relatively low. The above-mentioned wave energy generating devices have their own advantages and disadvantages, and there is a demand for improving the generating devices and increasing the power generation efficiency. Therefore, based on the development of existing wave energy generation technology, there is an urgent need for a wave energy generation device with high wave energy absorption rate, low cost, and high reliability in long-term operation.

The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the present invention, and are not intended to limit the present invention.

As shown in Fig. 1, Fig. 2 and Fig. 2, a flexible capsule wave energy power generation device of the present invention includes a base bed 1 fixed on the bottom of the water, and is characterized in that a silicone tube 2 with a flexible structure is fixed on the base bed 1, One end of the silicone tube 2 is sealed, and the other end of the silicone tube 2 is connected with a vertical pipe 3 for transferring water, and the top of the vertical pipe 3 is provided with an air inlet chamber 4 and an exhaust chamber 5; The chamber 4 is provided with an air inlet 10, and an air inlet valve 9 is arranged between the air inlet chamber 4 and the inner chamber of the vertical pipe 3; the top of the exhaust chamber 5 is provided with an air outlet 8, and the air outlet A wind generator 6 is arranged above the port 8, and above the exhaust port 8 is a circular channel, and the wind generator 6 is fixed on the central axis of the circular channel. An exhaust valve 7 is provided between the exhaust chamber 5 and the inner cavity of the vertical pipe 3 .

In the present invention, the flexible capsule formed by the silicone tube 2 has strong shrinkage, and the silicone tube 2 is filled with water, and the silicone tube 2 shrinks or expands with the change of the crest and trough of the external wave to form a pulsation to transmit the water body , so that the water body in the silicone tube 2 rushes to the vertical pipe 3 at its tail end, and the water level in the vertical pipe 3 is compressed to discharge and quickly inhale air along with the sudden rise and fall of the pulsation; when the water level drops suddenly, as shown in Figure 4 As shown by the dotted arrow line in the figure, the gas enters the inner cavity of the vertical pipe 3 through the air inlet 10, the air inlet chamber 4, and the air inlet valve 9 in turn; when the water level rises suddenly, as shown by the solid arrow line in Figure 4, The gas in the inner cavity of the vertical pipe 3 is compressed, and the compressed gas is exhausted through the exhaust valve 7, the exhaust chamber 5, and the exhaust port 8 in sequence, and the wave energy is converted into flowing compressed air. The impeller 11 of the quasi-wind generator, the top of the impeller 11 is connected with the wind generator 6, and the gas blows the impeller 11 of the wind generator to drive the wind generator 6 to generate electricity.

The power generating device of the invention has simple structure and low manufacturing cost; the wave energy is captured by the silica gel tube, and the wave energy utilization rate is high; the silica gel structure is stable and reliable; the silica gel tube has strong corrosion resistance and low maintenance cost.

In order to improve the stability of the device, preferably, the silicone tube 2 is in a sealed semi-cylindrical shape and fixedly laid on the foundation bed 1 . In this preferred embodiment, the semi-cylindrical silicone tube 2 can be stably placed on the panel of the foundation bed 1, and only the upper semicircle expands and contracts up and down with the waves, which is more stable. Of course, it is not ruled out that the silicone tube 2 can also be a cylindrical structure and be directly placed on the panel of the foundation bed 1.
