It is a mature and widely used power generation method with advantages such as mature technology, large power generation and relatively low cost. However, thermal power generation will increase greenhouse gas emissions and release more air pollutants, which will have a greater impact on environmental pollution and climate warming. Therefore, people are paying more and more attention to the development of clean energy.

[0003] Wave power generation uses the kinetic energy of waves and converts it into electrical energy through special mechanical devices or hydraulic systems. Wave power generation has the advantages of high energy density and strong predictability. However, wave power generation technology is still in the development stage and faces technical challenges, high costs and environmental adaptability issues, which require further research and development and optimization. Summary of the invention

[0004] The purpose of the present invention is to overcome the above problems and provide a swing type power generation device. To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A swing type power generation device comprises a workbench, a power generation component and a support component;

[0006] The workbench is provided with a receiving cavity inside, and the receiving cavity is provided with a liquid for increasing the swing frequency and swing amplitude of the workbench, and the liquid does not fill the receiving cavity and can swing freely in the receiving cavity;

[0007] The power generation assembly includes a rotating assembly, a transmission assembly and a generator. The rotating assembly includes a transmission rod, a connecting rod, a pendulum and a slideway. The slideway is a circular slideway. The transmission rod is arranged at the center of the circular slideway. Both ends of the connecting rod are fixedly connected to the transmission rod and the pendulum respectively. The pendulum rotates along the slideway under the action of an external power source and drives the transmission rod to rotate. The transmission rod drives the generator to generate electricity through the transmission assembly.

[0008] The support assembly includes a support seat and a spring, and two ends of the spring are fixedly connected to the top of the support seat and the bottom of the workbench respectively; the number of the support assembly is one group or multiple groups.

[0009] As an improvement, the transmission assembly is a gearbox, which is provided with an input shaft and an output shaft, the input shaft and the output shaft are perpendicular to each other, the end of the input shaft is fixedly connected to the transmission rod and keeps synchronous rotation, the output shaft is arranged parallel to the working surface of the workbench, and the output shaft is linearly connected to the rotor shaft of the generator.

[0010] As an improvement, the rotor shaft of the generator is linearly connected to the output shaft of the gearbox via a coupling.

[0011] As an improvement, the liquid occupies 40-70% of the volume of the accommodating chamber.

[0012] As an improvement, a mast and a sail are provided at the center of the top of the workbench; the mast and the sail are fixed to the workbench through a supporting frame.

DETAILED DESCRIPTION

[0029] The present invention is described in detail and specifically by specific examples below to provide a better understanding of the present invention, but the following examples do not limit the protection scope of the present invention.

[0030] Example 1

[0031] This embodiment discloses a swing-type power generation device, which includes: a workbench 1 , a power generation component 2 and a support component 3 .

[0032] The workbench 1 adopts an octagonal structure. A receiving chamber 11 is provided inside the workbench 1. A liquid 4 for increasing the swing frequency and swing amplitude of the workbench is provided in the receiving chamber 11. In this embodiment, the liquid 4 is water, and the amount of the liquid 4 accounts for 60% of the volume of the receiving chamber 11. The liquid 4 does not fill the receiving chamber 11 and can freely sway in the receiving chamber 11.

[0033] The power generation assembly 2 includes a rotating assembly 21, a transmission assembly 22 and a generator 23. The rotating assembly 21 includes a transmission rod 211, a connecting rod 212, a pendulum 213 and a slideway 214; the transmission rod 211 is arranged at the center of the slideway 214, and the two ends of the connecting rod 212 are fixedly connected to the transmission rod 211 and the pendulum 213 respectively. The slideway 214 is a circular slideway with the transmission rod 211 as the center.

[0034] When the workbench 1 tilts and swings under the action of external force, the pendulum 213 rotates along the slideway 214 under the action of gravity and drives the transmission rod 211 to rotate. After the transmission rod 211 rotates, it drives the generator 23 to generate electricity through the transmission assembly 22. A pulley 215 matching the slideway 214 is provided at the bottom of the pendulum 213, and the pendulum 213 slides along the slideway 214 through the pulley 215. The main function of the slideway 214 is to support and fix, which can support the pendulum 213 and limit the pendulum 213 on the slideway 214 to avoid derailment during operation. The pulley 215 can reduce the friction when the pendulum 213 rotates and improve the energy conversion efficiency.

[0035] The transmission assembly 22 includes a gearbox 221, which is provided with an input shaft 222 and an output shaft 223, the input shaft 222 and the output shaft 223 being perpendicular to each other. The end of the input shaft 222 is fixedly connected to the transmission rod 211 and keeps synchronous rotation, and the output shaft 223 is parallel to the working surface of the workbench.

[0036] The generator 23 is disposed on the workbench 1 . The output shaft 223 is linearly connected to the rotor shaft 231 of the generator 23 via a coupling 224 .

[0037] like Figure 1 and Figure 3 As shown, the generator 23 and the transmission assembly 22 are arranged in the area surrounded by the slide 215. The connecting rod 212 is arranged above the generator 23 and the transmission assembly 22, and the pendulum 213 bypasses the outside of the generator 23 and the transmission assembly 22 when swinging or rotating. The above structure can simplify the connection between the generator 23 and the gearbox 221 and the workbench 1, making it more stable and reliable. The above design can effectively increase the length of the connecting rod 212, increase the torque when the pendulum 213 moves, and improve the power generation effect. At the same time, the above structure can optimize the space utilization on the workbench 1, so that the distribution of the working components on the workbench 1 is more reasonable.

[0038] The support assembly 3 includes a support seat 31 and a spring 32, and the two ends of the spring 32 are respectively fixedly connected to the top of the support seat 31 and the bottom of the workbench 1; the number of the support assembly 3 can be one or more groups. In this embodiment, the number of the support assembly 3 is 8 groups, which are evenly distributed at the bottom of the workbench 1.

[0039] When working, this embodiment can be fixed on the hull through the support seat 31. When the hull tilts and swings under the action of the waves, it can drive the workbench 1 to tilt and swing. Under the action of gravity, the pendulum 213 rotates along the slideway 214 and drives the input shaft 222 to rotate, and then drives the rotor of the generator 23 to rotate through the gearbox 221 to generate electricity.

[0040] In this embodiment, a plurality of springs 32 are provided at the bottom of the workbench 1, and a receiving chamber 11 for storing the liquid 4 is provided inside. The provision of the springs 32 and the receiving chamber 11 can further increase the instability of the workbench 1, increase the swing amplitude and the swing frequency when the workbench swings, and make the workbench 1 swing continuously under the action of external force, so that the pendulum 213 can slide continuously along the slideway 214, thereby achieving the purpose of continuous high-efficiency power generation.

[0041] Example 2

[0042] This example discloses a swing-type power generation device.

[0043] In this embodiment, a mast and a sail 5 are provided at the center of the top of the workbench 1 ; the mast and the sail 5 are fixed on the workbench 1 via a supporting frame 6 .

[0044] The other structures of this embodiment are the same as those of Embodiment 1.

[0045] This embodiment adds a mast and a sail 5 on the basis of the first embodiment, increases the acquisition of external energy, and further utilizes wind energy to improve the swing effect of the workbench 1, increase its swing amplitude and swing frequency. On the sea surface, the sea waves and wind energy can be comprehensively utilized to improve the power generation efficiency.

[0046] At the same time, since the present embodiment can swing with the help of wind energy, the application scenario of the present embodiment is more extensive. It can be used not only on the sea surface, but also on the site with sufficient wind energy and vibration energy.

[0047] The electric power generated by the device of the present invention can be transmitted to a storage battery through a rectifying device or transmitted to the outside through a transmission line.

[0048] Traditional wave energy power generation devices mainly include pendulum wave power generation systems and buoyancy pendulum wave energy power generation devices.

[0049] The pendulum wave power generation system uses the pendulum to absorb wave energy and convert it into mechanical energy, and drives the power generation device through the rotation of the pendulum. The device has a simple structure, is easy to maintain and repair, and is suitable for a variety of marine environments.

[0050] The buoyancy pendulum wave energy power generation device uses the direct action of waves on the buoyancy pendulum to convert the up and down movement of the waves into mechanical energy of the buoyancy pendulum and then into electrical energy. The device can include a three-level or four-level energy conversion process, which increases the controllability and stability of energy conversion.

[0051] Traditional wind power generation devices usually have large impellers. The impellers require abundant and stable wind energy resources to drive them, and have high requirements for the site selection of power generation sites. In addition, traditional wind power generation devices occupy a large area, which is not conducive to deployment in cities or areas with limited space. In addition, the manufacturing, transportation and maintenance costs of large impellers are relatively high, and they also have certain visual and noise impacts on the environment.

[0052] Compared with traditional wave power or wind power generation devices, this solution has the following technical advantages:

[0053] 1. The present invention can comprehensively utilize multiple energy sources, including wave energy, wind energy, gravitational potential energy, spring elastic potential energy, and liquid surge energy, etc., which can comprehensively improve the energy capture efficiency, improve the power generation efficiency, and at the same time improve the applicability of the device so that it can be used in a variety of work scenarios.

[0054] 2. The present invention is provided with a mechanism for enhancing the swing, and through the design of the internal liquid and the spring, the swing amplitude and frequency of the workbench are increased, thereby achieving the purpose of increasing the swing frequency and swing amplitude of the pendulum, and further improving the power generation efficiency.

[0055] 3. The present invention adopts a modular design, and each component is assembled in a modular manner, which is convenient for maintenance and replacement of components and reduces long-term operating costs.

[0056] 4. The present invention has strong environmental adaptability, can comprehensively utilize a variety of natural forces, and has good power generation capabilities under different environmental conditions.

[0057] 5. The present invention adopts a swinging design, which enables it to swing under the action of various natural forces, thereby capturing energy and achieving the effect of improving energy utilization efficiency.

[0058] The specific embodiments of the present invention are described in detail above, but they are only examples, and the present invention is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
