Description

[0002] Currently, with the increasing demand for clean energy, concentrated photovoltaic (CPV) power generation technology has become a key focus in the photovoltaic power generation field due to its ability to reduce the amount of photovoltaic cells used and lower costs.

The multi-level concentrating module 3 achieves efficient and uniform light concentration, improving the concentration effect; the adjustment module 2 allows for angle adjustment to ensure concentration efficiency; and the heat dissipation module 5 effectively dissipates heat from the cells, improving energy utilization and overall functionality. Specific settings are as follows: Please refer to Figure 1 Support platform 1 serves as the basic support component of the system, with internal assembly space for installing the battery. The height of support platform 1 is set at 40-60cm to avoid ground obstruction and ensure stability. It can be made of steel to meet structural strength requirements, and its top is flat to ensure stable assembly of the directional module 2. The battery is placed at the bottom of support platform 1, and ventilation holes are provided on the side walls of support platform 1 to prevent overheating of the internal equipment.

[0022] Please continue to refer to this. Figure 1 The steering module 2 includes a steering gimbal 21, a pitch motor push rod 22, and a bullseye bearing 23. The base of the steering gimbal 21 is fixedly mounted on the top of the support platform 1 to enable the steering gimbal 21 to rotate 360°. The base of the bullseye bearing 23 is fixedly connected to the center of the turntable of the steering gimbal 21, and the base of the pitch motor push rod 22 is connected to the side of the turntable of the steering gimbal 21.

[0023] The multi-level focusing module 3 includes a main frame 31, a planar reflector array 32, a Fresnel lens array 33, a reflector cup 34, a universal joint 35, a light tracking sensor 36, a mirror turntable 37, and a motor lead screw guide rail 38. The bottom of the main frame 31 is fixed to the steering end of the bullseye bearing 23 in the orientation module 2. The main frame is made of aluminum alloy to balance lightweight and strength. The bottom of the main frame 31 is also connected to the output end of the pitch motor push rod 22. The photovoltaic cell module 4 is screwed onto the main frame 31. The top of the main frame 31 is fixedly installed above the front panel of the photovoltaic cell module 4. The Fresnel lens array 33 corresponds to the photovoltaic cell module 4 and is used to drive the pitch motor push rod 22 and the photovoltaic cell module 4 to rotate synchronously 360° through the steering gimbal 21. Furthermore, the pitch motor push rod 22 can be used to achieve pitch drive orientation adjustment, thereby meeting the requirements of solar azimuth adjustment.

[0024] The light tracking sensor 36 is fixedly mounted at the top of the main frame 31, and the light tracking sensor 36 is connected to the input end of the electronic control module through a circuit. The output end of the electronic control module is connected to the steering gimbal 21 and the pitch motor push rod 22 through a circuit, so as to send the light intensity to the electronic control module in real time with the help of the light tracking sensor 36. The electronic control module controls the steering gimbal 21 and the pitch motor push rod 22 to move according to the signal at regular intervals, thereby realizing that the Fresnel lens array 33 and the photovoltaic cell module 4 automatically follow the sun's orientation.

[0025] It should be noted that the electronic control module includes a power supply component and a controller. The controller can be selected from, but is not limited to, a single-chip microcontroller control board of model AT80C51 or a microcontroller of model STM32.

[0026] The planar reflector array 32 consists of several planar reflectors, which are respectively mounted on the top side of the main frame 31 via universal joints 36. The reflective surfaces of the planar reflectors all face inwards. When the photovoltaic cell module 4 faces the sun, the angle of the planar reflectors can be adjusted by the universal joints 36 to effectively capture scattered light and accurately focus the reflected light onto the Fresnel lens array 24. A 2-4cm windproof gap is left between adjacent reflectors to effectively reduce wind resistance.

[0027] Specifically, the base of the motor screw guide 38 is fixedly mounted on both top sides of the main frame 31. The motor screw guide 38 has a linear kinetic energy output end, and the linear kinetic energy output end of the motor screw guide 38 is driven and fixedly connected to the mirror turntable 37.

The mirror array 32 can adjust its height relative to the Fresnel lens array 33 based on the real-time altitude of the sun via the mirror turntable 37 and the motor lead screw guide rail 38. For example, when the sun is at noon altitude, the plane mirror array 32 is adjusted to its highest position based on the motor lead screw guide rail 38, and when the sun is at sunrise or sunset altitude, the plane mirror array 32 is adjusted to its lowest position based on the motor lead screw guide rail 38. At the same time, the orientation of the plane mirror array 32 can be automatically adjusted with the help of the mirror turntable 37, which effectively improves the overall functionality and practicality.

[0028] The side of the main frame 31 is provided with a reflector cup 34 below the Fresnel lens array 33. The reflector cup 34 is respectively provided with the Fresnel lens array 33 and the photovoltaic cell module 4 to reflect the diverging light to the cell and improve the light concentration efficiency. Preferably, the outer wall of the reflector cup 34 is covered with a reflective film to enhance the reflection effect.

[0029] Please continue to refer to this. Figure 1 The heat dissipation module 5 includes a high heat flux density radiator 51, a circulation pump 52, and a circulation pipe 53. The high heat flux density radiator 51 is a hollow box with its upper surface directly laminated to the photovoltaic cell module 4.

The circulation pump 52 is installed inside the water tank 6 to form a pumping circulation loop.

[0030] As another preferred embodiment, the side wall of the support platform 1 is provided with a sliding track, and a snow removal and dust removal strip is mounted on the track via a motor-driven screw mechanism. The snow removal and dust removal strip is correspondingly attached to the photovoltaic panel of the photovoltaic cell module 4, so as to drive the snow removal and dust removal strip along the track via the motor-driven screw mechanism to clean the dust and snow on the photovoltaic panel of the photovoltaic cell module 4 and avoid shading that affects the light transmittance.

[0031] As another preferred embodiment, the outer side of the water tank 6 is covered with an insulation layer 61, and the water tank 6 is also connected to a hot water device 62, such as a domestic water device, to effectively realize the energy storage and further utilization of the heat source inside the water tank 6, thereby improving the resource utilization rate.

[0032] In one optional implementation, the water tank 6 and the hot water equipment 62 are both fixedly connected to the turntable side of the steering gimbal 21 via a bracket, so that the water tank 6 and the hot water equipment 62 can operate synchronously with the photovoltaic cell module 4 that is adapted to the sun's orientation, thereby reducing the risk of pipe entanglement.

[0033] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art.
