Description

Technical Field

[0001] The invention relates to the field of energy collection devices, and in particular to a composite coal mining machine vibration energy collection device based on an arc structure. Background Art

[0002] Coal mining machine vibration energy harvesting technology is mainly used in the coal mining industry. Coal mining machines generate vibrations of a certain frequency when working. The energy harvesting structure bends due to these vibrations, and the piezoelectric element is compressed or stretched in the process, thereby generating electrical energy. This process can be achieved through electromagnetic induction or piezoelectric effect. Utilizing the above vibration energy, a self-powered solution is provided for coal mining machine monitoring systems, sensors, signal transmission equipment and other devices, which helps reduce dependence on traditional power supplies, improve the equipment's autonomous operation capabilities, and reduce maintenance costs.

[0003] However, there are several problems with the existing vibration energy collection devices for coal mining machines. First, the energy conversion efficiency of the device is low. The energy conversion efficiency of piezoelectric materials under high-frequency or low-frequency vibrations is often not high, resulting in unsatisfactory energy collection effects and poor adaptability of the device. The vibration characteristics of coal mining machines have a certain randomness. Existing energy collection devices are often optimized for specific frequencies, resulting in unstable performance under different working conditions. The structure of the device is relatively complex. In order to improve the energy collection efficiency, the design often requires the addition of components, resulting in a complex overall system structure and increased difficulty in installation and maintenance. The reliability of the device is poor. The coal mining environment is harsh, and the vibration and impact force are large, which may cause material fatigue and damage. The existing technology has failed to fully consider the reliability under long-term work in material selection and structural design.

[0004] Therefore, we made improvements to this and proposed a composite coal mining machine vibration energy collection device based on an arc structure. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the scheme of this application:

[0019] 1. In order to solve the problem that existing energy collection devices in the prior art are often optimized for specific frequencies, resulting in unstable performance and poor applicability under different working conditions, the present application combines two energy conversion mechanisms by setting an arc frame and a piezoelectric layer. The arc frame excites the piezoelectric material to produce piezoelectric output through vibration, and produces electromagnetic output through the cooperation of magnets and coils.

In addition, the energy management system aggregates and adjusts the piezoelectric and electromagnetic outputs, which can smooth the energy output and ensure stable power supply. It is suitable for devices with high requirements for stable power supply, which improves the applicability of energy harvesting devices.

[0021] 3. The arc-shaped structural design enables it to work in a variety of vibration environments, with strong adaptability, and can effectively cope with the multi-frequency vibration characteristics of the coal mining machine under different operating conditions. The use of high-strength materials and optimized structural design enhances the durability of the device in high-intensity vibration and harsh environments, and extends its service life. The design of the arc frame is relatively simple, which reduces the overall complexity of the device and helps to reduce manufacturing and maintenance costs.

[0022] 4. By integrating piezoelectric and electromagnetic mechanisms, the device can make full use of the various energy forms generated by the coal mining machine, improve the flexibility of energy collection, and the composite design reduces the friction of moving parts, reduces wear, reduces the maintenance frequency of equipment, and enhances overall reliability. By utilizing the vibration energy of the coal mining machine for self-powering, it reduces dependence on traditional batteries, reduces the risk of environmental pollution, and supports sustainable development. In addition to its application in coal mining machines, it can also be expanded to self-powered systems of other vibration sources, such as transportation vehicles and industrial equipment, and has broad market prospects.
