Description

Technical Field

[0001] The present invention belongs to the technical field of power generation devices, and particularly relates to a device and method for generating electricity by using the relative displacement in the normal direction between two flat plates. Background Art

[0002] Energy is the cornerstone of the development of human society. However, with the rapid growth of the global population and the acceleration of the industrialization process, the global energy structure is facing unprecedented challenges. These problems not only threaten our economic development and living standards, but also cause great pressure on the ecological environment. Nowadays, while technological progress is promoting the rapid development of various industries, the demand for electric power resources is becoming more urgent. The pollutant emissions generated by the traditional energy supply system during the energy consumption process seriously threaten the stability of the earth's ecosystem, making the ecological environment deteriorate continuously. Solar power generation and wind power generation, as two important renewable energy power generation methods, although having the advantages of being clean and renewable, also have some disadvantages. For example, solar power generation generates electricity through sunlight and can only work during the day. Weather conditions such as rain, snow, cloudy days, and fog days will affect the efficiency of photovoltaic power generation. And due to the low energy density of solar energy, photovoltaic power generation requires a large floor area. Wind power generation generates a large amount of noise pollution during operation, and the initial investment and maintenance costs are relatively high. Therefore, the research on new power generation methods is extremely urgent. There are many devices that will undergo pressing behaviors during operation, such as speed bumps for vehicle deceleration and high-speed moving yachts.

[0003] A speed bump is a raised device fixed on the road surface. When a vehicle passes by, the raised speed bump will exert a resistance on the vehicle, thereby achieving the deceleration of the vehicle. At the same time, the raised speed bump will lift the vehicle, increasing the gravitational potential energy of the vehicle, resulting in the waste of the vehicle's gravitational potential energy. V-bottom yachts are mostly made of lightweight materials to reduce the hull weight, improve the speed and flexibility. Driven by a powerful power system, the center of gravity of the yacht moves backward, and the bow will naturally lift, reducing the contact area with the water surface, thereby reducing the friction force and increasing the speed. When the speed of the yacht reaches a certain level, the yacht may completely leave the water and jump, increasing the gravitational potential energy of the yacht, resulting in the waste of the yacht's gravitational potential energy. Therefore, there is an urgent need to design a device for effectively recovering the energy generated by phase displacement. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and method for generating electricity by using the relative displacement in the normal direction between two flat plates. When the pressable upper plate is pressed and moves downward, it drives the linear power generation mechanism and the rotary power generation mechanism to generate electricity simultaneously, achieving higher energy utilization efficiency.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A device for generating electricity by using the relative displacement in the normal direction between two flat plates, comprising: a linear power generation mechanism and a rotary power generation mechanism, wherein the linear power generation mechanism and the rotary power generation mechanism are installed between a pressable upper plate and a lower plate;

[0007] The linear power generation mechanism includes a connecting rod installed below the pressable upper plate, a permanent magnet is installed on the connecting rod, a spring is provided between the lower end of the permanent magnet and the lower plate, a copper coil is fixed on the lower plate in a spiral shape, and the copper coil is sleeved outside the permanent magnet and the spring;

[0008] The rotary power generation mechanism includes a rack installed on the pressable upper plate, the rack meshes with a first gear, the first gear meshes with a second gear, the second gear meshes with a third gear when rotating counterclockwise, and the second gear disengages from the third gear when rotating clockwise. The third gear and the fourth gear are installed on a first transmission shaft, the fourth gear meshes with a fifth gear, and the fifth gear is connected to a flywheel and a generator through a second transmission shaft, and the generator is installed on a support.

[0009] Further, the first gear and the third gear are fixed on a support plate through shafts, the second gear is fixed in a groove on the support plate through a shaft, and the second gear performs a horizontal translation movement in the groove.

[0010] Further, the pitch circle diameters of the second gear and the third gear are the same, and the pitch circle diameter of the first gear is larger than the pitch circle diameters of the second gear and the third gear.

[0011] Further, when the second gear and the third gear are meshed, the center distance between the second gear and the first gear is increased, the pitch circles of the second gear and the first gear are not tangent, but still meshed, and the meshing tooth area is reduced.

[0012] Further, the fourth gear and the fifth gear are bevel gears, and the pitch circle diameter of the fifth gear is smaller than the pitch circle diameter of the fourth gear.

[0013] Further, the copper coil and the generator are respectively externally connected to a power storage device.

[0014] Further, the inner diameter of the copper coil is larger than the outer diameters of the spring and the permanent magnet.

[0015] Further, the support plate is fixed on the lower plate.

[0016] The present invention may further include:

[0017] A power generation method of a device for generating electricity by using the relative displacement in the normal direction between two flat plates as described above. When the pressable upper plate is pressed and moves downward, it simultaneously drives the linear power generation mechanism and the rotary power generation mechanism to generate electricity together;

[0018] When the pressable upper plate drives the connecting rod to move downward, the connecting rod drives the permanent magnet to move downward. The copper coil is stationary relative to the lower plate, and a relative displacement is generated between the permanent magnet and the copper coil for power generation, realizing the power generation of the linear power generation mechanism;

[0019] When the pressable upper plate moves upward, the pressable upper plate drives the connecting rod to move upward, the connecting rod drives the permanent magnet to move upward. The copper coil is stationary relative to the lower plate, and a relative displacement is generated between the permanent magnet and the copper coil for power generation, realizing the power generation of the linear power generation mechanism;

[0020] When the pressable upper plate is pressed and moves downward, it also drives the rack to move downward. The rack converts the vertical downward movement into the clockwise rotation of the first gear. The first gear drives the counterclockwise rotation of the second gear, and at the same time gives the second gear a horizontal leftward force, pushing the second gear to move horizontally to the left along the groove and engage with the third gear, thereby driving the clockwise rotation of the third gear. The third gear drives the fourth gear to rotate clockwise through the first transmission shaft. The fourth gear drives the fifth gear to rotate downward. The fifth gear drives the flywheel to store energy and the generator to generate electricity through the second transmission shaft, realizing the power generation of the rotary power generation mechanism.

[0021] Furthermore, when the pressable upper plate moves upward, it also drives the rack to move upward. The rack converts the vertical upward movement into the counterclockwise rotation of the first gear. The first gear drives the second gear to rotate clockwise, and at the same time gives the second gear a horizontal rightward force, pushing the second gear to move horizontally to the right along the groove and disengage from the third gear, so that the second gear rotates idly to avoid the reverse rotation of the generator.

[0022] The beneficial effects of the present invention are as follows:

[0023] Through the cooperation of each component of the present invention, when in use, when the pressable upper plate is pressed and moves downward, it can drive the linear power generation mechanism and the rotary power generation mechanism to generate electricity simultaneously. Through the electromagnetic induction phenomenon generated by the magnet and the coil and the generator, the normal relative displacement between the two plates is converted into electric energy, avoiding the waste of energy, integrating the two power generation methods of linear power generation and rotary power generation, and realizing higher energy utilization efficiency.

[0024] The present invention uses a flywheel for rotational energy storage. When the pressable upper plate moves upward, the second gear and the third gear disengage, but the second transmission shaft where the fifth gear, the flywheel and the generator are located can still rotate, and then generate electricity; when the pressable upper plate moves downward again, the second gear and the third gear engage, driving the third gear to rotate. The third gear drives the fourth gear to rotate coaxially, and the fourth gear drives the fifth gear to rotate. If the flywheel has not stopped rotating before, it will accelerate the rotation speed of the second transmission shaft where the fifth gear, the flywheel and the generator are located, and then improve the power generation efficiency of the generator.
