Description

Technical Field

[0001] The invention belongs to the technical field of wave energy power generation, and in particular relates to a shipborne portable wave energy power generation component and application thereof. Background Art

[0002] At present, fossil energy is decreasing, environmental problems are becoming more and more serious, and the development and utilization of clean energy are receiving more and more attention. There are many kinds of huge energy in the ocean, among which wave energy is one of the most important energy sources of ocean energy. The purpose of alleviating energy pressure and improving the environment can be achieved by developing and utilizing wave energy. Commonly used wave energy power generation devices include pendulum type, wave surface raft type, oscillating water column type, etc., but they all have the following problems: large structure, high requirements for wave conditions, low power generation, and most of the equipment is expensive and has high maintenance costs. The reason is that the core power generation component of the current wave energy power generation device relies on the traditional electromagnetic induction generator. Because the wave frequency is low, the dispersion is wide, and the wave peak is random, the performance of the electromagnetic induction generator is greatly limited.

[0003] Friction nanogenerators have the advantages of flexible shape, small size, and high efficiency in collecting low-frequency waves. However, the friction surface of the friction nanogenerator is easily worn, and the output power of a single generator unit is low. They need to be set up in parallel to form a wave energy generation array to increase the output power. Summary of the invention

[0004] The present invention provides a shipborne portable wave energy power generation component and its application to solve the technical problems existing in the known technology. The component has good durability, high output power, simple structure, low cost and is easy to carry.

[0005] The present invention adopts a technical solution to solve the technical problems existing in the known technology: a ship-borne portable wave energy power generation component, including a sea snake type floating shell, a closed cabin is arranged inside the sea snake type floating shell, an air gap is arranged between the closed cabin and the sea snake type floating shell, the closed cabin is connected to the bottom of the sea snake type floating shell by an interference spring, a friction nano generator is installed in the closed cabin, the main body adopts a stacked structure, from top to bottom, a friction film, an induction electrode layer and a generating electrode base are arranged, a polytetrafluoroethylene ball rolling along the longitudinal direction is arranged on the upper surface of the main body, the polytetrafluoroethylene ball is provided with a limit cover, both ends of the limit cover are elastic films, and the limit cover is installed on the upper surface of the main body; when the power generation component floats under the action of waves, the polytetrafluoroethylene ball rolls on the friction film to generate friction, resulting in charge transfer, generating induced charges on the induction electrode layer, and generating alternating current is generated through an external circuit.

[0006] The friction film is made of nylon film.

[0007] The sea snake type floating shell adopts a retractable structure.

[0008] The sensing electrode layer is a sputtered copper layer.

[0009] The light emitting electrode substrate is made of an acrylic plate.

[0010] The enclosed cabin is made of acrylic plate.

[0011] The sea snake type floating shell is provided with an acrylic resin coating.

[0012] A plurality of parallel-connected friction nanogenerators are arranged inside the sealed cabin.

[0013] Each of the friction nanogenerators is provided with a plurality of polytetrafluoroethylene balls which generate rolling friction with the friction film.

[0014] Another technical solution adopted by the present invention to solve the technical problems existing in the known technology is: an offshore working vessel, which is powered by the above-mentioned ship-borne portable wave energy power generation component.

[0015] The advantages and positive effects of the present invention are:

[0016] 1) The motor adopts a multi-layer structure as the main body, and multiple polytetrafluoroethylene balls that are easy to obtain electrons are used to roll on the main body. The rolling friction surface is not easy to wear and has good durability; it helps to increase the friction charge density, thereby increasing the output voltage and power, and improving the power generation performance of the friction nanogenerator.

[0017] 2) An air gap is set to isolate the power generation electrode from the water, because the dielectric constant r of water is very high. If there is no gap, the electric field will be in the water. This will lead to a significant increase in capacitance, which will cause the output voltage of the device to become lower. The air gap structure between the water snake shell and the closed cabin effectively avoids this situation, thereby increasing the power generation of the system.

[0018] 3) Simple structure, low cost, easy to use, and easy to carry on ships. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0026] See also Figure 1 to Figure 6 A ship-borne portable wave energy power generation component includes a sea snake type floating shell 1, a closed cabin 2 is arranged inside the sea snake type floating shell 1, an air gap is arranged between the closed cabin 2 and the sea snake type floating shell 1, and the closed cabin 2 is connected to the bottom of the sea snake type floating shell 1 by an interference spring 3.

[0027] A friction nanogenerator is installed in the closed cabin 2. The main body adopts a stacked structure, which includes a friction film 5, an induction electrode layer 6 and an electrode substrate 7 from top to bottom. A polytetrafluoroethylene ball 8 rolling along its longitudinal direction and a limiting cover 9 for limiting the polytetrafluoroethylene ball 8 are provided on the upper surface of the main body of the friction nanogenerator. Elastic films 10 are used at both ends of the limiting cover 9.

[0028] When the power generation component floats under the action of waves, the polytetrafluoroethylene balls roll on the friction film to generate friction, which causes charge transfer and generates induced charges on the induction electrode layer, which are then conducted through an external circuit to generate alternating current.

[0029] In this embodiment, the friction film 5 is made of nylon film. The electrode layer 6 is a sputtered copper layer. The electrode substrate 7 is made of an acrylic plate. The enclosed cabin 2 is made of an acrylic plate. The sea snake type floating shell 1 is made of a flexible inflatable material and has a retractable structure for easy storage and carrying. The sea snake type floating shell 1 is provided with an acrylic resin coating to prevent seawater corrosion. A plurality of parallel friction nanogenerators are provided inside the enclosed cabin to increase the power generation. Each friction nanogenerator is provided with a plurality of polytetrafluoroethylene balls 8 to generate rolling friction with the friction film 5 to increase the power generation.

[0030] See also Figure 1 The above-mentioned ship-borne portable wave energy power generation component is connected to the offshore operation vessel 12 by a cable 11 to provide power for the offshore operation vessel 12.

[0031] Working principle and application of the present invention:

[0032] See also Figure 6 Under the action of waves, the sea snake-shaped retractable floating shell 1 floats up and down, the interference spring 3 connected to the closed cabin 2 bends under the action of waves, the closed cabin 2 tilts, and the polytetrafluoroethylene ball 8 rolls longitudinally on the friction film 5 to generate charge transfer, and induced charges are generated on the induction electrode layer 6. The induced charges are output through the external circuit to generate alternating current. After the waves pass through the sea snake-shaped floating shell, the closed cabin 2 will tilt in another direction. Under the promotion of the interference spring 3, the polytetrafluoroethylene ball 8 rolls longitudinally in another direction, increasing the frequency of induced charge generation. The generated alternating current outputs electrical energy after passing through the rectifier bridge to achieve power generation, and can also be connected to both ends of the capacitor for energy storage and then power generation.

[0033] In the generator unit, the polytetrafluoroethylene ball 8 rubs against the friction film, and the electrodes of the two are opposite. When the ball rolls and rubs on the friction film 5, due to frictional electrification, the ball loses electrons during the rolling friction process, and the friction film gains electrons, thereby generating frictional electricity. According to the principle of electrostatic induction, due to the change of charge, the induction electrode generates induced charge, which is derived through the external circuit to continuously generate alternating current.

[0034] See also Figure 1 The above-mentioned power generation component provides part of the power for the ship, realizing the effective utilization of wave energy during the ship's parking process. The friction nanogenerator in the power generation component is used to collect wave energy. A plurality of them are used, and the plurality of generators are connected in parallel by connecting a rectifier bridge and an external circuit, which can increase the output power of the power generation component. At the same time, it also has the advantages of good working stability and strong durability, thereby making the power generation component of the present invention have broad uses and good application prospects. The power generation component of the present invention also has the advantages of low cost, simple structure, high power generation and easy maintenance. In addition, the use of power generation components on offshore operating ships can buffer the impact of waves on the hull, can appropriately reduce the degree of roll of the ship, and can ensure the stability of the ship construction process to a certain extent. More importantly, this power generation component is relatively small as a whole, easy to place and recycle, simple and portable, and has a wide range of applications.

[0035] In summary, the present invention discloses a shipborne portable wave energy power generation component, which mainly includes a sea snake-shaped flexible support shell, a plurality of polytetrafluoroethylene friction balls, an induction electrode (nylon film, sputtered copper layer, supporting acrylic plate power generation substrate), an acrylic closed cabin and a flexible interference spring. Under the action of external waves, the water waves pass through the water snake structure shell, the friction nanogenerator unit tilts up and down, and the spring connected to the acrylic box will bend due to the vibration of the incident water wave. Next, the acrylic box will tilt, causing the ball to roll on the nylon membrane slide, the ball and the top nylon membrane of the induction motor will rub, generate charge transfer, generate charge on the induction electrode, and output alternating current through the external connection circuit. In addition, due to the addition of the spring, the instantaneous frequency plus the frequency conversion leads to an increase in current and power. Part of the power is provided to the ship by nano friction power generation, realizing the effective utilization of wave energy during the ship's parking process. The size of the power generation unit can be flexibly designed according to the application environment and requirements, and multiple power generation units can be connected in parallel to form a wave energy power generation array. In addition, the presence of the energy collection device in the device of the present invention has a buffering effect on the impact of waves, which can appropriately reduce the rolling degree of the ship and ensure the stability of the ship construction process to a certain extent. More importantly, the device is relatively small in size, easy to place and recycle, simple and portable, and has a wider range of applications.
