Description
Technical Field
The invention relates to the technical field of solar panels, in particular to a piezoelectric-driven intelligent adjusting device for a solar panel.
Background
The solar cell panel is a green and environment-friendly renewable energy device, converts solar radiation energy into electric energy through a photoelectric effect or a photochemical effect, and is widely applied to the fields of traffic, communication, petroleum, weather and the like.
In practical use, the power generation efficiency of the solar cell panel is greatly related to the solar radiation angle (i.e. the included angle between the incident direction of sunlight and the top surface of the solar cell panel). The sunlight incidence direction of the working environment of the solar cell panel is constantly changed along with the time due to the day and night alternation and four-season alternation generated by the rotation and revolution of the earth. At present, most solar cell panel is installed on the fixed bolster, can't realize the angle modulation, has seriously influenced solar cell panel's work efficiency. A small amount of solar cell panel devices with angle adjusting functions also use an electromagnetic motor, a hydraulic mechanism and a pneumatic mechanism as power elements, but the devices have a plurality of structural and performance defects:
1. the existing solar cell panel angle adjusting device mainly takes an electromagnetic motor, a hydraulic mechanism and a pneumatic mechanism as power elements, and the adjusting device has large volume and complex structure, and increases the preparation cost and the processing difficulty; in addition, the performance of the electromagnetic motor, the hydraulic mechanism and the pneumatic mechanism is easily interfered by temperature, humidity and electromagnetic environment, and the application range of the adjusting device is limited.
2. The existing solar cell panel angle adjusting device is long in reaction time and not easy to control in movement, and mostly only has the angle adjusting function in the vertical direction, so that the solar cell panel cannot obtain the optimal working state in time, and the energy conversion efficiency of the solar cell panel is influenced.
3. The conventional solar cell panel angle adjusting device has noise in the working process, is easy to generate heat and cannot continuously work for a long time, and the adjusting device needs frequent maintenance work such as lubrication, liquid supplementation, air supplementation and the like, so that the operation cost of equipment is increased, and the service life is seriously influenced.
4. The existing solar cell panel angle adjusting device is heavy in weight, high in energy consumption and difficult in structure integration, and cannot meet the structural and performance requirements required by industry development under the development trend of light weight, miniaturization and intellectualization of new energy industry.
The piezoelectric material is a functional material with piezoelectric effect and inverse piezoelectric effect, has high rigidity, high strength, long service life, high energy conversion efficiency and good machining performance, and can realize the mutual conversion of electric energy and mechanical energy. The piezoelectric driver based on the inverse piezoelectric effect directly acts deformation or vibration on the driven part to carry out mechanical driving or mechanical control, and does not need to transmit motion to the driven part through a transmission mechanism such as a gear or a belt wheel and the like in the traditional power element, so that the piezoelectric driver has the characteristics of small volume, simple structure, humidity and heat resistance, no noise, low energy consumption, large driving force, no electromagnetic interference, high energy density, high response speed, high control precision and the like. In recent years, piezoelectric actuators have been used in the fields of micro-electromechanical systems, biotechnology, and medical health.
Regarding the inverse piezoelectric effect and the piezoelectric driver:
the piezoelectric material is a functional material having an inverse piezoelectric effect, and as shown in fig. 1, when an electric field is applied to the piezoelectric material, the piezoelectric material not only generates polarization, but also generates deformation proportional to the electric field intensity, and the deformation form (elongation or contraction) is related to the direction of the electric field, and when the applied electric field is removed, the deformation disappears, and this phenomenon of converting electric energy into mechanical energy is called the inverse piezoelectric effect.
The piezoelectric actuator is a novel actuator manufactured by utilizing the inverse piezoelectric effect of a piezoelectric material. When a certain voltage is input, the piezoelectric driver generates a deformation quantity which gradually increases along with the increase of the voltage, so that the electric energy is converted into mechanical motion. Currently, the piezoelectric drivers mainly include two types, a bimorph type piezoelectric driver and a stack type piezoelectric driver. As shown in fig. 2, the stacked piezoelectric actuator mainly comprises piezoelectric ceramic plates, internal electrodes, external electrodes, and the like, and adopts a mechanical series connection mode and an electrode parallel connection mode. Compared with a bimorph piezoelectric actuator, the stack type piezoelectric actuator has obvious advantages in deformation, driving force, energy conversion rate and stability.
