Abstract

Piezoelectric power generation belongs to the new green energy power generation. Piezoelectric materials are usually installed on vibration sources (such as roads and bridges) to convert the vibration energy into power. Its disadvantages are huge equipment, easy maintenance, low power generation efficiency, and power generation conditions. limit.

This creation belongs to the category of piezoelectric power generation, but it is not passive power generation in energy-consuming collection mode, but the application of the principle of the swing of the bell hammer. The pendulum action shaft rolls the piezoelectric device on the bearing surface of the structural frame to generate electricity.

The pendulum swing only needs to consider the loss of minimal friction and air resistance, so it can almost continue to swing without providing additional energy. Such a generator is not only simple in equipment, but also has low operation and maintenance costs. The power generation process is almost completely silent. This invention will change the civilization of human use of energy.

Description

Pendulum piezoelectric generator

The present invention relates to a piezoelectric generator, especially a generator that applies the principle of a pendulum and gravity, and the weight of the pendulum repeatedly presses the piezoelectric material device to generate electricity by swinging the pendulum.

At present, the main application method of piezoelectric power generation is to lay piezoelectric materials on vibration sources, such as roads and bridges. The piezoelectric material device that the car body presses the pavement through the road through the road and the weight of the car body generates electricity. The equipment is huge and the installation is expensive. The source of vibration is unstable, the loss of equipment is large, and the maintenance is quite troublesome.

Piezoelectric devices installed outdoors are not only prone to wear and tear, but they are also likely to cause circuit problems in case of weather changes, humidity, and overheating. The main method is to collect the energy consumption of other power devices, and the production of electricity is quite passive and cannot be stable and sustainable.

The new type uses the weight of the pendulum to press against the piezoelectric material to generate electrical energy. The pendulum swings to form the force of repeated compression, so that the piezoelectric device placed on the bearing surface of the structural frame or the axis of action of the pendulum generates electrical energy. It is for active piezoelectric power generation. , Without any source of vibration or pressure provided by the outside world.

1. The location of the piezoelectric material device

method one:

The piezoelectric material device is under the weight pressure of the pendulum on the structural frame (as shown in No. 5 of Figure 1)

1. The swing of the pendulum produces displacement of the point of force, and the weight of the pendulum presses on the original No. 5 (as shown in Figures 8 and 9), thus generating electricity.

2. Piezoelectric devices can be stacked in multiple layers to produce multiple power outputs. (As shown in Figure 2)

Method 2:

The piezoelectric material is installed on the axis of the pendulum (as shown in element 7 of Figure 1)

1. The swing of the pendulum produces displacement of the force point, and the weight of the pendulum presses on the original No. 5 (as shown in Figures 8 and 9), thus generating electricity.

2. Piezoelectric devices overlap in multiple layers, producing multiple power outputs. (As shown in Figure 2)

Method 3:

In the first and second integrated methods, piezoelectric materials (such as No. 5 and No. 7 components in Figure 1) are placed on the pendulum action shaft and the bearing surface of the structural body. This method has higher power generation efficiency.

2. Control of pendulum swing

1. Place electromagnets or other control devices on both sides of the pendulum (this design uses electromagnets as the design, considering that the energy loss of the electromagnet is lower than other equipment). When the pendulum swings to the extreme position on one side, use The electromagnet attracts to stabilize its swing.

2. When the pendulum swings to one side, the electromagnet on that side is energized to generate magnetic force. When the pendulum swings to the limit of the preset position on that side, the electromagnet is synchronously powered off and loses its magnetism, allowing the pendulum to move flexibly Swing back.

3. When the pendulum swings to the other side, the electromagnet on that side is energized to generate magnetic force. When the pendulum swings to the limit of the preset position on the side, the electromagnet is synchronously powered off and loses its magnetism, allowing the pendulum to flexibly Swing back.

4. The force of the pendulum action shaft pressing the piezoelectric material device is controlled by the weight adjustment of the overall pendulum.

5. Electromagnetic energy is to compensate for the kinetic energy loss caused by the friction and air resistance and other resistance of the swing. If the pendulum is properly designed, these losses can be minimized. For example, a traditional clock with a pendulous swing only needs to be wound every few months.

6. The power of electromagnetic energy can use the power generated by the power generation device itself. Therefore, the power generating device can generate power without energy.

3. Control of swing frequency

1. The frequency of swing is related to the frequency of electrical energy output, and is also related to the efficiency of the generator. Its control is the adjustment of the center of gravity of the pendulum. The longer the lower pendulum hammer, the slower the swing.

1. Under special circumstances, the pendulum action axis can be increased, and only the upper pendulum and the pendulum action axis and the pendulum rod form an integral pendulum, and the entire pendulum structure forms a tumbler or rocking chair.

2. In special cases, it is also possible to use the pendulum action shaft only, similar to a rugby ball or a half-moon type, as long as it can oscillate left and right steadily, a piezoelectric material device can be placed on the force bearing surface of the arc bottom of the pendulum action axis.

3. When this generator is used to generate alternating current, two generators (two-phase) or three generators (three-phase) must be operated together to control the time difference of the pendulum swing of each generator to achieve the phase of output power.
