Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a multifunctional photovoltaic support system. Background Art

[0002] In the context of the global response to climate change and the promotion of renewable energy, photovoltaic power generation has become a key development direction in the energy field with its significant advantages of cleanliness and sustainability, and has received extensive attention and in-depth application internationally. Photovoltaic support systems, as the basic support structure for the stable placement and efficient operation of photovoltaic modules, have long been stuck in the dilemma of functional limitations.

[0003] In the past, common photovoltaic support systems were mostly defined as having only basic load-bearing functions, that is, to firmly support photovoltaic modules at a predetermined angle and position to ensure their basic lighting and power generation conditions. Traditional design ideas focus on structural strength and stability considerations, but seriously ignore the increasingly diverse and stringent functional demands as the photovoltaic industry evolves rapidly. On the one hand, most support systems lack the ability to efficiently track and utilize the dynamic changes of sunlight. The position of the sun in the sky continues to change with time and season, and the incident angle of light at different times varies significantly. Fixed-angle supports make it difficult for photovoltaic modules to always maintain the best light-receiving posture, causing power generation efficiency to hover at a low level for a long time. For example, in the morning and evening, the solar altitude angle is low, the light is oblique, and the effective illumination area received by the photovoltaic modules is far less than the vertical incidence, so a lot of light energy is wasted.

[0004] On the other hand, the accumulation of dust, dirt and other impurities on the surface of photovoltaic modules is also a difficult challenge that affects the power generation efficiency. In outdoor environments, foreign objects such as sand, bird droppings, and leaf debris can easily adhere to the surface of the modules, forming a shielding barrier that weakens the light penetration rate. Conventional brackets do not have an integrated effective cleaning mechanism. Even if a cleaning device is added later, it is often necessary to build additional complex auxiliary structures, which not only destroys the overall aesthetic coordination, but also has poor compatibility with existing bracket systems in terms of mechanical installation and electrical control. It is also easy to generate safety hazards and operation and maintenance problems due to additional loads and complex line laying.

[0005] Furthermore, the temperature of the working environment of photovoltaic modules fluctuates violently, especially extreme high temperature conditions will interfere with the electrical properties of internal semiconductor materials, resulting in reduced power generation efficiency and shortened service life. Most of the existing bracket layouts do not take into account the temperature control factors. Simply relying on the heat dissipation design of the components themselves is far from meeting the needs of stable and efficient power generation under complex climatic conditions. When additional temperature control facilities are added, it is difficult to achieve seamless integration and precise temperature control due to the limitations of the original structure of the bracket. In summary, the traditional photovoltaic bracket system is in urgent need of innovation and upgrading to break through the shackles of a single support function. Summary of the invention

[0006] The object of the present invention is to provide a multifunctional photovoltaic support system integrating automatic tracking, intelligent temperature control, automatic cleaning and safety protection.

[0013] Furthermore, the branch pipe has at least one pair of nozzles which are symmetrical to each other and are arranged to tilt upwards.

[0014] Furthermore, each group of the temperature control components includes a temperature sensor and two heat dissipation fans, and the two heat dissipation fans are respectively directed toward two groups of mutually symmetrical photovoltaic modules.

[0031] Example 1

[0032] like Figure 1-Figure 8As shown, the present invention provides a multifunctional photovoltaic support system, including a support component 1, a cleaning component and a general control module. The support component 1 includes a plurality of columns 101, and two rotatable beams 2 parallel to each other are mounted on the top of the columns 101, and a photovoltaic component is mounted on each beam 2; the plurality of columns 101 are arranged at equal intervals along the length direction of the beam 2, and two bearing seats 102 are symmetrically fixedly installed on the top of each column 101, and the beam 2 is penetrated and installed on the bearing seat 102.

[0033] The photovoltaic assembly includes a photovoltaic panel 3 and a support frame 4 for supporting the photovoltaic panel 3. The photovoltaic panel 3 is fixedly mounted on the top of the support frame 4. The support frame 4 includes a main purlin 401 and an oblique brace 402. The main purlin 401 and the oblique brace 402 are fixedly mounted on the crossbeam 2 through a U-shaped checkpoint 403. The end of the oblique brace 402 away from the crossbeam 2 is connected to the main purlin 401 by bolts. The photovoltaic assembly also includes a plurality of photoelectric sensors arranged along the circumference of the photovoltaic panel 3.

[0034] A driving assembly for driving the cross beam 2 to rotate is installed on both sides of each column 101, and the driving assembly includes a linear actuator 5 and a swing arm 6. The swing arm 6 is fixedly connected to the cross beam 2, and the top of the linear actuator 5 is hinged to the bottom of the swing arm 6. The bottom of the linear actuator 5 is hinged to the column 101. The cross beam 2 is driven to rotate by the telescopic movement of the linear actuator 5, thereby realizing the angle adjustment of the photovoltaic module with the horizontal plane. The linear actuator 5 in this embodiment is a hydraulic cylinder, a cylinder or an electric telescopic rod.

[0035] The cleaning component includes a water tank 7 and a water pipe 8. The water tank 7 is equipped with a high-pressure water pump. The water pipe 8 is arranged between two groups of photovoltaic modules. A plurality of groups of cleaning nozzles 10 are arranged at intervals on the water pipe 8 between the two groups of photovoltaic modules. The specific arrangement structure is as follows: a plurality of branch pipes 9 are arranged at equal intervals on the water pipe 8 between the two groups of photovoltaic modules, and a plurality of nozzles 10 are symmetrically installed on each branch pipe 9, wherein at least one pair of mutually symmetrical nozzles 10 are arranged on the branch pipe 9 and are tilted upwards, respectively, to facilitate spray cleaning of the surface of the rotated photovoltaic module.

[0036] Multiple groups of temperature control components are arranged between every two adjacent columns 101, and each group of temperature control components includes two heat dissipation fans 12, which are respectively directed toward two groups of mutually symmetrical photovoltaic modules, and the heat dissipation of the lower surface of the photovoltaic panel 3 can be achieved through the heat dissipation fans 12. The heat dissipation fans 12 are installed in the following manner: a mounting beam 11 is welded between every two adjacent columns 101, and multiple groups of mounting brackets for fixing and installing the heat dissipation fans 12 are arranged at equal intervals on the mounting beam 11. The temperature control components also include a temperature sensor for real-time sensing of the external temperature.

[0037] In order to adjust the angle of the photovoltaic module according to the wind speed so that its windward area is minimized, a wind speed sensor is also required.

[0038] The linear drive 5, temperature sensor, photoelectric sensor and high-pressure water pump in the system are all electrically connected to the main control module, and the automatic tracking function, heavy snow protection function, strong wind protection function, automatic cleaning function and automatic temperature control function of the bracket system are realized through the main control module.

[0039] Automatic tracking function: By controlling the linear drive 5 on both sides of the column 101 to drive the photovoltaic assembly to rotate, the support system can automatically track the position of the sun during operation to increase the power generation of the photovoltaic support system. In order to achieve the above-mentioned automatic tracking function, photoelectric sensors are installed around the photovoltaic panel 3. The photoelectric sensors work based on the photoelectric effect and can sense changes in light intensity and light direction. The intensity of sunlight received by sensors at different positions will vary depending on the position of the sun. When the solar altitude angle changes, the light conditions received by each sensor change. By comparing the strength of the signals fed back by these sensors, the approximate position and height of the sun can be determined, thereby providing a basis for adjusting the tilt angle of the photovoltaic panel 3.

[0040] Heavy snow protection function: The bracket control system drives the two groups of photovoltaic modules to rotate in different directions according to the real-time weather conditions. The two linear drivers 5 on the column 101 respectively make the two groups of photovoltaic modules present a "human" shape structure, so that the snow on the photovoltaic panel 3 slides down, ensuring that there is no snow accumulation on the photovoltaic modules in heavy snow weather.

[0041] Strong wind protection function: The main control module automatically judges according to the wind speed (if automatic control is realized, a wind speed sensor needs to be set), so that the support system enters the strong wind protection mode, and uses the linear drive 5 to adjust the photovoltaic module to the horizontal level, so that the photovoltaic module has no inclination, and ensures that the windward area of ​​the photovoltaic module is minimized.

[0042] Automatic cleaning function: Overheating of photovoltaic modules not only affects the power generation efficiency of the photovoltaic support system, but also affects the service life of photovoltaic modules. When the main control module detects that the temperature of the photovoltaic module is too high, the support system automatically enters the temperature control mode, that is, the linear driver rotates the photovoltaic module to the working range of the temperature control components, and then the temperature control components cool down the photovoltaic module. The support temperature control and heat dissipation can dissipate heat on the upper and lower surfaces of the photovoltaic module respectively. The upper surface can use the cleaning component for water cooling, and the lower surface can use air cooling.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
