Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation device technology, specifically a new energy photovoltaic power generation device. Background Technology

[0002] Against the backdrop of global energy transition, photovoltaic (PV) power generation, as an important form of clean and renewable energy utilization, directly impacts energy conversion efficiency and application costs due to the performance of its equipment. Traditional new energy PV power generation devices generally suffer from the following technical bottlenecks: First, PV panels are mostly installed using fixed brackets, making it impossible to dynamically adjust the tilt angle according to changes in solar altitude and azimuth angles. This limits the efficiency of light reception, especially in high-latitude regions or under cloudy weather conditions, where power generation efficiency can drop by 20%-30%. Second, PV panels generate heat due to photoelectric conversion losses during operation. If heat cannot be dissipated in time, the power generation efficiency will decrease by about 5% for every 10°C increase in panel temperature. Furthermore, prolonged high temperatures will accelerate the aging of PV panels and shorten their lifespan. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figs. 1-3 As shown, this utility model provides a new energy photovoltaic power generation device, including a base 1, a support column 101 vertically arranged on the base 1, a photovoltaic panel assembly 102, an angle adjustment mechanism 2 for adjusting the tilt angle of the photovoltaic panel assembly 102, and a heat dissipation assembly 3 arranged on the back of the photovoltaic panel assembly 102.

[0026] In this embodiment, the base 1 is fixedly connected to the ground, roof, or other supporting structure through multiple pre-set mounting holes to form a stable foundation support. The support column 101 is vertically installed in the center of the base 1, extending upwards to support the photovoltaic panel assembly 102 and various functional mechanisms at the top. The layout design of the mounting holes allows for rigid fixing using bolts or embedded parts, ensuring that the device can withstand loads such as wind and vibration in outdoor environments.

[0027] The multi-mounting hole design enhances the device's environmental adaptability, allowing for flexible installation on flat ground, sloping roofs, or specialized brackets to meet the engineering needs of various scenarios. The rigid support structure strengthens the device's stability, reduces the risk of collapse under extreme weather conditions (such as typhoons and heavy rain), and extends its overall service life.

[0028] In this embodiment, multiple photovoltaic panels are fixed in a matrix arrangement on the rotating shaft 202, with a 5-10mm gap between adjacent photovoltaic panels to form an airflow channel. When external airflow passes through, the gaps guide the air to quickly pass through the surface and back of the photovoltaic panels, assisting the heat dissipation component 3 in reducing the panel temperature. This provides a buffer space for the thermal expansion and contraction of the photovoltaic panels, avoiding structural deformation caused by temperature stress, and also removes surface dust particles through air convection, reducing the load on the cleaning mechanism 4.

[0029] The photovoltaic panel assembly 102 is connected to the top of the support column 101 via an angle adjustment mechanism 2. The angle adjustment mechanism 2 includes a fixed base 201, a rotating shaft 202, a drive motor 203, and a transmission gear. The fixed base 201 is disposed at the top of the support column 101, and the rotating shaft 202 is rotatably disposed on the fixed base 201. The photovoltaic panel assembly 102 is fixedly connected to the rotating shaft 202.

[0030] The drive motor 203 is fixed to the mounting base 201 at the top of the support column 101, and its output shaft meshes with the driven gear on the rotating shaft 202 through a transmission gear. When the motor starts, the gear set transmits rotational power to the rotating shaft 202, driving the photovoltaic panel assembly 102 to rotate around the shaft, thereby adjusting the tilt angle. The angle sensor monitors the actual tilt angle of the photovoltaic panel in real time and feeds the signal back to the controller, forming a closed-loop control. When the sensor detects a deviation between the current angle and the preset optimal illumination angle (such as that which varies with the solar altitude angle), the controller automatically drives the motor 203 to adjust until the optimal angle is reached.

[0031] Gear meshing transmission features high precision and low backlash, ensuring smooth angle adjustment and positioning accuracy, and preventing photovoltaic panels from swaying in strong winds.

[0032] The heat dissipation component 3 includes a heat dissipation substrate 301, heat dissipation fins, and a heat dissipation fan 302. The heat dissipation substrate 301 is attached to the back of the photovoltaic panel component 102, the heat dissipation fins are disposed on the back of the heat dissipation substrate 301, and the heat dissipation fan 302 is disposed on one side of the heat dissipation fins.

[0033] The heat dissipation substrate 301 (made of aluminum) is tightly attached to the back of the photovoltaic panel, absorbing the heat generated during panel operation through thermal conduction (the efficiency of the photovoltaic panel decreases with increasing temperature, dropping by approximately 0.4% for every 1°C increase). The fins on the back of the substrate are evenly distributed in a comb-like pattern, diffusing heat to a larger surface area and enhancing natural heat dissipation. The cooling fan 302 forces airflow from one side of the fins, creating a directional airflow that accelerates heat exchange, significantly improving heat dissipation efficiency, especially in high-temperature, windless environments. The fan speed can be automatically adjusted by the controller based on temperature sensor signals (e.g., set to start at 50°C and stop at 40°C) to achieve energy-saving operation.

[0034] Furthermore, the aforementioned new energy photovoltaic power generation device is characterized in that the drive motor 203 is mounted on the fixed base 201, and the transmission gear is mounted on the output shaft of the drive motor 203 and meshes with the driven gear on the rotating shaft 202. High-precision angle adjustment, positioning error ≤0.5°; 2. High mechanical strength, adaptable to high-frequency outdoor adjustment requirements.

[0035] Furthermore, the mounting base 201 is also equipped with an angle sensor, which is used to detect the tilt angle of the photovoltaic panel assembly 102. This provides real-time feedback and automatic calibration without manual intervention; and allows for rapid restoration of the optimal angle in response to sudden changes in lighting conditions such as cloudy weather.

[0036] Furthermore, the heat dissipation substrate 301 is made of aluminum, and the heat dissipation fins are evenly distributed on the back of the heat dissipation substrate 301. The aluminum substrate combines lightweight and high thermal conductivity (thermal conductivity of approximately 205 W / (m·K)), reducing weight by 60% compared to a steel substrate while meeting heat dissipation requirements. The fin spacing is matched with the fan airflow to avoid airflow short-circuiting. After optimization through fluid dynamics simulation, the heat dissipation efficiency is improved by 30% compared to traditional flat plate structures.

[0037] Furthermore, the base 1 is provided with multiple mounting holes for fixing the base 1 to the ground or other supporting structure. It is compatible with various installation scenarios (ground / roof / bracket), features modular installation, and reduces the construction cycle by 50%.

[0038] Furthermore, the photovoltaic panel assembly 102 includes multiple photovoltaic panels arranged in a matrix, with gaps between adjacent panels to facilitate airflow. This promotes air convection, assists in natural heat dissipation, reduces dust accumulation, and decreases the frequency of cleaning.

[0039] Further explanation is provided: a cleaning mechanism 4 is included, which is disposed above the photovoltaic panel assembly 102. The cleaning mechanism 4 includes a mounting frame 401, a drive shaft 403, a lead screw 402, a cleaning brush 405, and a cleaning motor 404. The cleaning brush 405 is connected to the drive shaft 403, and the cleaning motor 404 is connected to the drive shaft 403. The cleaning motor 404 is disposed on the mounting frame 401, and the cleaning brush 405 moves along the surface of the photovoltaic panel assembly 102 via the lead screw 402.

[0040] A cleaning motor 404 is fixed to a mounting bracket 401 above the photovoltaic panel, driving a lead screw 402 to rotate. This causes a nut seat to reciprocate along the lead screw 402, while a cleaning brush 405, fixed to the nut seat, simultaneously sweeps the surface of the photovoltaic panel. The brush bristles are made of soft nylon or silicone material and adhere to the panel surface with a pressure of 10-15N to remove dust, bird droppings, and other contaminants. The controller can be set to perform timed cleaning (e.g., every morning) or trigger-based cleaning (activated when the light intensity sensor detects a decrease in light transmittance exceeding a threshold).

[0041] Furthermore, the bristles of the cleaning brush 405 are made of soft material, and the length of the cleaning brush 405 is adapted to the width of the photovoltaic panel assembly 102. The length of the cleaning brush 405 perfectly matches the width of the photovoltaic panel assembly 102 (error ≤ 2mm), ensuring that a single movement can cover the entire panel surface without any blind spots. The lead screw 402 transmission has a self-locking function; when stopped, the cleaning brush 405 is fixed in a non-working position (such as the right edge) to avoid blocking sunlight.

[0042] Furthermore, it also includes a control box 103, which is located on the side of the support column 101. The control box 103 contains a controller, which is electrically connected to the angle adjustment mechanism 2, the cleaning mechanism 4, and the heat dissipation component 3.

[0043] The controller (microprocessor or PLC) inside the control box 103 integrates multi-channel sensor inputs (angle, temperature, light intensity) and equipment outputs (motor, fan, cleaning mechanism 4) interfaces. Through a preset algorithm (such as a solar trajectory tracking algorithm), it calculates the optimal photovoltaic panel angle in real time and coordinates the operation logic of heat dissipation and cleaning functions.

[0044] In the early morning, the cleaning brush 405 removes accumulated dust from the night before. Then, based on feedback from the angle sensor, the photovoltaic panels are adjusted to the initial angle for the day's sunlight. When the temperature exceeds a threshold at noon, the cooling fan 302 automatically starts, while simultaneously fine-tuning the photovoltaic panel angle to prevent localized overheating. After power generation ceases in the evening, the photovoltaic panels are controlled to return to a horizontal position to reduce wind resistance. Fully automated operation reduces manual maintenance costs, making it particularly suitable for remote areas or large-area photovoltaic power plants. Multi-mechanism collaborative control maximizes energy efficiency. Actual measurements show that compared to traditional fixed-angle photovoltaic devices, annual power generation is increased by 15%-20%.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
