Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a novel flexible hydraulic photovoltaic support. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the energy and power sector is undergoing a low-carbon transformation, and the application of wind power, photovoltaics, and energy storage is becoming more and more widespread. The importance of clean energy is becoming increasingly prominent. Solar energy, as one of the most promising clean energy sources, is developing rapidly. Among them, photovoltaic modules are common solar energy utilization devices that can absorb light energy and convert it into electrical energy, and are widely used.

[0003] Existing photovoltaic (PV) modules have the following drawbacks in use: The smallest component in a PV power generation system is the PV module, and PV mounting systems, as the supporting carriers for these modules, are mainly divided into fixed mounting systems and tracking mounting systems. Fixed mounting systems are further categorized into optimal tilt angle fixed mounting systems, sloping roof fixed mounting systems, and tilt angle adjustable fixed mounting systems. Tracking mounting systems are further categorized into flat single-axis tracking mounting systems, inclined single-axis tracking mounting systems, and dual-axis tracking mounting systems. As PV mounting system applications become increasingly complex and environmental adaptability requirements become more stringent, flexible tracking PV mounting systems will find wider application scenarios. Existing PV module mounting systems require a large amount of cement foundations, steel, and transmission components during construction, resulting in complex structures and high production, construction, and maintenance costs. Therefore, we propose a novel flexible hydraulic PV mounting system. Utility Model Content

[0004] The main objective of this invention is to provide a novel flexible hydraulic photovoltaic support system, which saves more on steel and cement foundation costs than fixed photovoltaic supports and conventional inclined single-axis photovoltaic supports. Furthermore, it allows for more efficient solar energy utilization by manually adjusting the optimal tilt angle of the photovoltaic modules in different seasons, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel flexible hydraulic photovoltaic (PV) support includes a cement base, crossbeams, and PV panels. Crossbeams are horizontally installed between the tops of the cement base, and PV panels are spaced apart on the tops of the crossbeams. A vertical main frame is vertically installed on the shaded side of the PV panels, and a horizontal main frame is horizontally installed on the shaded side of the PV panels. A support rod is vertically fixed to the top of the cement base, and the top of the support rod is connected to the vertical main frame via a pivot connector A. A hydraulic cylinder is installed on the top of the cement base next to the support rod, and a hydraulic rod is connected to the top of the hydraulic cylinder. A pivot connector B is installed at the top of the hydraulic rod and connected to the end of the horizontal main frame via the pivot connector B.

[0006] Furthermore, the photovoltaic panel has a horizontally spaced connecting frame laid on the shaded side; the horizontally spaced connecting frame serves to position and support the photovoltaic panel.

[0007] Furthermore, a support column is vertically fixed at the top of the cement base at the bottom of the cross frame. A connecting sleeve is installed on the surface of the cross frame, and the top of the support column is inserted into the connecting sleeve. Limiting holes are opened on the side of the connecting sleeve and the side of the support column, and pins are inserted between the limiting holes. The support column and the connecting sleeve at the top of the cement base cooperate to support and fix the cross frame. Multiple sets of limiting holes of different heights are provided on the side of the connecting sleeve. Aligning them with the limiting holes on the side of the support column and inserting pins can fix the height of the cross frame. By adjusting the height of the limiting holes between the support column and the connecting sleeve, the height of the cross frame can be adjusted, thereby adjusting the overall tilt angle of the photovoltaic panel. Taking the Northern Hemisphere as an example, the uppermost hole is used in summer, the middle hole is used in spring and autumn, and the lowermost hole is used in winter.

[0008] Furthermore, sleeves are installed at intervals inside the cross frame, and the bottom end of the vertical main frame passes through the inside of the sleeves; the sleeves serve as a connection between the cross frame and the vertical main frame, allowing the photovoltaic panels to deflect normally.

[0009] Furthermore, an oil supply pipe is provided on the side of the hydraulic cylinder, and a fixing rod is vertically fixed to the top of the cement base at the bottom of the hydraulic cylinder. A rotating shaft connector C is installed on the top of the fixing rod and is connected to the bottom of the hydraulic cylinder through the rotating shaft connector C. The oil supply pipe is connected to an external oil supply device, thereby realizing the control of the operation of the hydraulic cylinder. The fixing rod plays a connecting role between the cement base and the hydraulic cylinder, and the rotating shaft connector C located at the connection point allows the angle of the hydraulic cylinder to deflect within a certain range.

[0010] Compared with the prior art, this utility model has the following beneficial effects: The crossbeam and support rod, as the main support components of the photovoltaic panel, are fixed to the top of the cement base. The crossbeam is connected to the bottom of the photovoltaic panel via a sleeve, and the support rod is connected to the middle of the sun-facing side of the photovoltaic panel. The hydraulic cylinder and hydraulic rod, as adjustment components, are connected to the end of the sun-facing side of the photovoltaic panel. The rotating shaft connector A allows the photovoltaic panel to be angled at the top of the support rod. When the hydraulic rod extends or retracts, it pushes the side of the photovoltaic panel. Simultaneously, the rotating shaft connectors B and C at the connection point allow the operation of the hydraulic cylinder to adjust the angle of the photovoltaic panel. During use, if the hydraulic cylinder controls the hydraulic rod to retract, the height of the photovoltaic panel near the hydraulic rod continuously decreases. If the hydraulic cylinder... The hydraulic cylinder controls the lifting of the hydraulic rod, which continuously raises the height of the photovoltaic panel near the hydraulic rod. By controlling the hydraulic cylinder, the angle of the photovoltaic panel can be adjusted. The angle and direction of the photovoltaic module can be automatically adjusted according to the position of the sun, thereby maximizing energy generation efficiency. Compared with existing tracking bracket components, this reduces the need for fixed steel pipes and cement foundations. In the case of a photovoltaic plant of the same capacity, this solution saves more on steel and cement foundation costs compared with fixed photovoltaic brackets and conventional inclined single-axis photovoltaic brackets, greatly reducing project construction investment and subsequent maintenance costs. Furthermore, it allows for manual adjustment of the optimal tilt angle of the photovoltaic module in different seasons, achieving more efficient solar energy utilization. At the same time, the hydraulic adjustment structure is simple and durable. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-12 As shown, a novel flexible hydraulic photovoltaic support includes a cement base 1, a crossbeam 2, and photovoltaic panels 3. The crossbeam 2 is horizontally installed between the tops of the cement base 1, and photovoltaic panels 3 are installed at intervals on the tops of the crossbeam 2. A vertical main frame 301 is vertically installed on the shaded side of the photovoltaic panels 3, and a horizontal main frame 302 is horizontally installed on the shaded side of the photovoltaic panels 3. A support rod 6 is vertically fixed on the top of the cement base 1, and the top of the support rod 6 is connected to the vertical main frame 301 through a pivot connector A601. A hydraulic cylinder 7 is installed on the top of the cement base 1 on the side of the support rod 6, and a hydraulic rod 701 is connected to the top of the hydraulic cylinder 7. A pivot connector B703 is installed on the top of the hydraulic rod 701 and is connected to the end of the horizontal main frame 302 through the pivot connector B703.

[0026] The photovoltaic panel 3 is horizontally spaced with connecting frames 303 on its shaded side. A pillar 4 is vertically fixed to the top of the cement base 1 at the bottom of the cross frame 2. A connecting sleeve 401 is installed on the surface of the cross frame 2, and the top of the pillar 4 is inserted into the connecting sleeve 401. Limiting holes 402 are provided on the sides of both the connecting sleeve 401 and the pillar 4, and pins 403 are inserted between the limiting holes 402. The horizontally spaced connecting frames 303 provide positioning and support for the photovoltaic panel 3. The pillar 4 is located at the top of the cement base 1. In conjunction with the connecting sleeve 401, it plays a role in supporting and fixing the cross frame 2. Multiple sets of limiting holes 402 of different heights are provided on the side of the connecting sleeve 401. Aligning it with the limiting holes 402 on the side of the support column 4 and inserting the pin 403 can fix the height of the cross frame 2. By adjusting the height of the limiting holes 402 between the support column 4 and the connecting sleeve 401, the height of the cross frame 2 can be adjusted, thereby adjusting the overall tilt angle of the photovoltaic panel 3. Taking the Northern Hemisphere as an example, the uppermost hole is used in summer, the middle hole is used in spring and autumn, and the lowermost hole is used in winter.

[0027] The cross frame 2 has sleeves 5 installed at intervals inside, and the bottom end of the vertical main frame 301 passes through the sleeves 5. The hydraulic cylinder 7 has an oil supply pipe 702 on its side. The bottom of the hydraulic cylinder 7 has a fixing rod 704 fixed vertically at the top of the cement base 1. The top of the fixing rod 704 is equipped with a rotating shaft connector C705, which is connected to the bottom of the hydraulic cylinder 7. The sleeves 5 connect the cross frame 2 and the vertical main frame 301, allowing the photovoltaic panel 3 to deflect normally. The oil supply pipe 702 connects to an external oil supply device, thereby controlling the operation of the hydraulic cylinder 7. The fixing rod 704 connects the cement base 1 and the hydraulic cylinder 7. The rotating shaft connector C705 at the connection point allows the angle of the hydraulic cylinder 7 to deflect within a certain range.

[0028] It should be noted that this utility model is a novel flexible hydraulic photovoltaic support. In use, the crossbeam 2 and support rod 6 serve as the main support components for the photovoltaic panel 3, fixed to the top of the cement base 1. The crossbeam 2 is connected to the bottom end of the photovoltaic panel 3 via a sleeve 5. The support rod 6 is connected to the middle of the shaded side of the photovoltaic panel 3. The hydraulic cylinder 7 and hydraulic rod 701, as adjustment components, are connected to the shaded end of the photovoltaic panel 3. The pivot connector A601 allows the photovoltaic panel 3 to rotate at the top of the support rod 6. When the hydraulic rod 701 extends or retracts, it pushes the side of the photovoltaic panel 3. Simultaneously, the pivot connectors B703 and C705 at the connection point allow the operation of the hydraulic cylinder 7 to adjust the angle of the photovoltaic panel 3. During use, if the hydraulic cylinder 7 controls the hydraulic rod 701 to retract, the photovoltaic panel 3 moves closer to... The height of one end of the hydraulic rod 701 continuously decreases. If the hydraulic cylinder 7 controls the hydraulic rod 701 to rise, the height of the photovoltaic panel 3 near the hydraulic rod 701 continuously increases. By controlling the hydraulic cylinder 7, the angle of the photovoltaic panel 3 can be adjusted. The angle and direction of the photovoltaic module can be automatically adjusted according to the position of the sun, thereby maximizing the energy generation efficiency. Compared with the existing tracking bracket components, it reduces the need for fixed steel pipes and cement foundations. In the case of photovoltaic plant areas of the same capacity, the application of this solution can save more on steel and cement foundation costs compared with fixed photovoltaic brackets and conventional inclined single-axis photovoltaic brackets, greatly saving on engineering construction investment and subsequent maintenance costs. It can also achieve more efficient solar energy utilization by manually adjusting the optimal tilt angle of the photovoltaic module in different seasons. At the same time, the hydraulic adjustment structure is simple and durable.
