Description

Technical Field

[0001] The utility model relates to the technical field of solar energy application, in particular to a windproof photovoltaic charging shed fixed adjustment integrated structure. Background Art

[0002] Photovoltaic charging sheds, as an innovative application that combines photovoltaic power generation with charging facilities, are gradually being widely used. However, in practical applications, photovoltaic charging sheds face many challenges, especially stability and safety issues in strong wind environments. In the existing designs of photovoltaic charging sheds, most structures are relatively simple and lack effective wind protection measures. Common fixing methods usually rely only on simple support columns and foundation connections, which cannot cope with the huge impact force brought by strong winds. When encountering strong winds, photovoltaic panels and supporting structures are susceptible to direct wind impact, causing structural deformation, damage or even collapse, which not only affects normal charging services, but may also cause serious safety hazards.

[0003] The traditional photovoltaic charging sheds do not take the flow characteristics of wind into consideration in their design, and there is no specially designed photovoltaic panel mounting frame, which results in large wind resistance of the photovoltaic panels, causing the entire structure to be under greater pressure in the wind. At the same time, due to the lack of an elastic buffering mechanism, the impact of wind force is directly transmitted to the structure, which can easily cause vibration and fatigue damage, shortening the service life of the photovoltaic charging shed. In addition, most of the existing photovoltaic panel mounting frames are fixed and cannot be flexibly adjusted according to wind direction and sun position. On the one hand, this reduces the efficiency of photovoltaic power generation, and on the other hand, when strong winds come, the wind resistance cannot be reduced by changing the direction of the photovoltaic panels, which increases the risk of structural collapse. At this stage, a windproof photovoltaic charging shed with a fixed and adjustable integrated structure is needed. Utility Model Content

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1 , a windproof photovoltaic charging shed fixed adjustment integrated structure of this embodiment includes:

[0030] A photovoltaic panel mounting frame, a support column, an adjustment unit, and a control detection unit for controlling the movement of the adjustment unit, wherein the photovoltaic panel mounting frame is connected to the upper end of the support column, and the adjustment unit is installed at the connection between the photovoltaic panel mounting frame and the support column;

[0031] The adjustment unit includes a telescopic mechanism and a driving mechanism, wherein the driving mechanism is installed to the side wall of the telescopic mechanism, one end of the telescopic mechanism is connected to the side of the support column, and the other end of the telescopic mechanism is connected to the bottom end of the photovoltaic panel mounting frame through a connecting rod, and is used for adjusting the angle of the photovoltaic panel mounting frame. The control and detection unit includes a wind direction sensor and a microcontroller, wherein the wind direction sensor is installed to the side wall of the photovoltaic panel mounting frame, the signal output end of the wind direction sensor is connected to the microcontroller, and the microcontroller is connected to the driving mechanism through a data line.

[0032] Specifically,

[0033] This embodiment provides a windproof photovoltaic charging shed with an integrated fixed and adjustable structure, which aims to improve the stability and adaptability of the photovoltaic charging shed in complex environments.

[0034] like Figure 1 As shown, the structure mainly includes a photovoltaic panel mounting frame, a support column 1, an adjustment unit and a control detection unit. The photovoltaic panel mounting frame serves as the main structure for carrying photovoltaic panels, and is composed of a main beam 10, a secondary beam 11, a mounting panel and a support arm 9. A high-strength aluminum alloy material 6061 aluminum alloy is selected for the photovoltaic panel mounting frame, and its tensile strength can reach 290MPa, and its yield strength is about 240MPa, with good comprehensive performance. For key stress-bearing parts, such as the main beam 10 supporting the photovoltaic panel and the part connected to the rotating mechanism, thickened plates or increased reinforcing ribs are used to improve local strength. A reinforcing rib with a thickness of 5 mm is added to the bottom of the main beam 10, which can significantly improve its bending resistance. In terms of surface treatment, an anodizing process is used to form an oxide film with a thickness of 10 to 25 microns on the surface of the aluminum alloy, which can not only improve corrosion resistance, but also increase surface hardness and wear resistance.

[0035] like Figure 4 As shown, the end of the secondary beam is fixedly connected to the side of the main beam 10 by welding, which enhances the strength of the overall frame. A sleeve is provided at the end of the main beam 10, and the support arm 9 is inserted into the sleeve and welded to form a closed welded joint. The mounting panel is horizontally installed above the stable frame formed by the main beam 10 and the secondary beam 11. A special groove is provided on the upper surface of the mounting panel for mounting the photovoltaic panel. At the same time, L-shaped locks are provided around the mounting panel, one end of the L-shaped lock is fixed to the side of the mounting panel, and the other end is pressed to the upper surface of the photovoltaic panel. The part where the L-shaped lock contacts the photovoltaic panel is made of elastic material, including a rubber pad with a certain thickness. When strong wind acts, the impact force on the photovoltaic panel will cause the elastic material to deform to a certain extent, thereby allowing the photovoltaic panel to have a slight displacement and absorb a certain degree of buffering force.

[0036] like Figure 2 As shown, the support column 1 is used as the basic support part of the entire structure. It is made of high-strength steel pipes or steel sections. Its bottom is fixed by anchor bolts that penetrate deep into the ground and are firmly combined with the reinforced concrete foundation. A ball joint seat is provided at the upper end of the support column 1, and a ball head that matches the ball joint seat is provided at the bottom of the photovoltaic panel mounting frame. Through this ball joint connection method, the photovoltaic panel mounting frame can be more flexibly adjusted in angle. In addition, the adjustment unit is divided into two completely identical parts, which are symmetrically connected to the two ends of the photovoltaic panel mounting frame. When the microcontroller issues a command, the adjustment unit at one end starts to act. Figure 3As shown, for example, if the telescopic mechanism in the adjustment unit at one end begins to extend, that is, the pressure ring rises, the telescopic rod is extended through the connecting rod, thereby pushing this end of the photovoltaic panel mounting frame to rise. At the same time, the adjustment unit at the other end receives the instruction of the microcontroller, the corresponding telescopic mechanism shortens, the pressure ring descends, and the telescopic rod is driven to contract, so that the other end of the photovoltaic panel mounting frame descends. The speed and number of rotations of the driving motor 6 are exactly the same, and the rotation direction is opposite. When it is necessary to adjust the angle or position of the photovoltaic panel mounting frame, the rotating ring is rotated through the gear set 5 at the output end of the reducer 7. The gear set 5 includes a driving gear 8 and a driving gear. The driving gear is connected to the output end of the reducer 7. The driving gear 8 drives the rotating ring. Due to the cooperation between the internal thread of the rotating ring and the external thread of the connecting sleeve, the rotating ring will move along the connecting sleeve. The connecting sleeve moves up and down, and the up and down movement of the rotating ring drives the telescopic leg 2 to perform telescopic movement through the connecting rod. When the rotating ring moves upward, the fixed ring connected thereto is also driven to move upward. Since one end of the connecting rod is connected to the outer wall below the fixed ring through a connecting shaft, the upward movement of the fixed ring will generate a pulling force on the connecting rod, so that the end of the connecting rod connected to the fixed ring is lifted upward. At the same time, the other end of the connecting rod is connected to the telescopic leg 2 through the connecting shaft. Since the overall length of the connecting rod remains unchanged and one end is pulled upward, under the force transmission, the connecting rod will generate an inward pulling force on the telescopic leg 2, thereby causing the telescopic leg 2 to contract. The other end of the telescopic leg 2 is connected to the bottom of the photovoltaic panel mounting frame. When the telescopic leg 2 is extended, it will push the photovoltaic panel mounting frame to lift up or tilt to one side; when the telescopic leg 2 is shortened, it will pull the photovoltaic panel mounting frame downward or tilt to the other side. In addition, the telescopic mechanism also includes an electromagnetic lock, and mounting grooves matching the size of the electromagnetic lock are respectively processed on the contact surface of the connecting rod and the fixed ring. The main body of the electromagnetic lock is embedded in these mounting grooves, and the outer shell of the electromagnetic lock is fixed to the connecting rod and the fixed ring respectively by screws or welding. When the telescopic mechanism does not need to be adjusted and needs to maintain its current state, the electromagnetic lock is powered on and started, and the lock core of the electromagnetic lock will extend to fill the gap between the connecting rod and the fixed ring, thereby preventing the connecting rod from rotating or moving relative to the fixed ring. Since the movement of the connecting rod is restricted, even if the rotating ring continues to rotate or other external forces act, the telescopic mechanism cannot change its length, thereby maintaining its current state.

[0037] The wind direction sensor 3 in the control detection unit is fixed to the outside of the side wall of the photovoltaic panel mounting frame through a mounting bracket. A fixing plate 4 is provided at the joint between the mounting bracket and the outside of the side wall. The fixing plate 4 is firmly connected to the photovoltaic panel mounting frame through a plurality of fixing bolts. A support seat is vertically extended from the outside of the fixing plate 4. The mounting bracket is fixed to the support seat. The wind direction sensor 3 can detect the change of wind direction in real time and transmit the signal to the microcontroller. The microcontroller is connected to the driving mechanism through a data line. After receiving the signal of the wind direction sensor 3, the microcontroller processes and analyzes it, and then sends the corresponding instruction to the driving mechanism. The driving mechanism controls the telescopic mechanism according to the instruction, and drives the photovoltaic panel mounting frame to adjust the angle through the connecting rod to adapt to the change of wind direction. When encountering strong wind weather, the wind direction sensor 3 quickly senses the change of wind direction and transmits the signal to the microcontroller. The microcontroller pre-stores preset algorithms and programs. These programs contain calculation rules for the angles required to adjust the photovoltaic panel mounting frame under different wind direction conditions. When the microcontroller receives the processed wind direction information, it will calculate the current angle value that needs to be adjusted according to these rules. After the calculation is completed, the microcontroller immediately sends the corresponding instruction to the driving mechanism. After receiving the command, the driving mechanism starts the driving motor 6. Through the deceleration and torque-increasing effect of the reducer 7 and the transmission of the gear set 5, the rotating ring is driven to rotate, so that the telescopic mechanism is extended or shortened. The action of the telescopic mechanism is transmitted to the photovoltaic panel mounting frame through the connecting rod, so as to adjust the angle of the photovoltaic panel mounting frame, reduce the force of the wind on the entire structure, and prevent collapse. After the photovoltaic panel mounting frame is adjusted to a suitable angle, the microcontroller starts the electromagnetic lock to fix the connecting rod position to ensure that the angle of the photovoltaic panel mounting frame does not change. When the telescopic mechanism needs to be adjusted again, the electromagnetic lock is powered off, the lock core is retracted, and the connecting rod resumes its active state. The telescopic mechanism can perform telescopic actions normally to achieve angle adjustment.

[0038] The anti-collapse fixing structure of the windproof photovoltaic charging shed of this embodiment can effectively adapt to different environmental conditions and ensure the stable operation of the photovoltaic charging shed.

[0039] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
