Description

[0002] As a core device for realizing the conversion of solar energy to electric energy, the photovoltaic panel is a core component in the photovoltaic power generation device. The photovoltaic panel is usually fixed to the ground at a specific angle by a support. One side of the photovoltaic panel is a light-receiving surface. The light-receiving surface of the photovoltaic panel receives sunlight and converts light energy into electric energy.

[0003] However, the existing photovoltaic power generation device has significant deficiencies in wind resistance design.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0029] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0030] As Figures 1 to 9 shown, a wind-resistant photovoltaic power generation device includes an outer frame 1, a plurality of foldable folding photovoltaic panel units are arranged in the outer frame 1, each folding photovoltaic panel unit includes a first photovoltaic panel assembly 2 and a second photovoltaic panel assembly 3, the first photovoltaic panel assembly 2 and the second photovoltaic panel are connected through a hinge 16; both sides of the first photovoltaic panel assembly 2 are respectively provided with a rotating shaft and are rotatably connected with both sides of the outer frame 1 through the rotating shaft; both sides of the second photovoltaic panel assembly 3 are respectively provided with a connecting groove 3-1; both sides of the outer frame 1 are slidably connected with a sliding block 12 corresponding to the connecting groove 3-1, the sliding block 12 is provided with a movable shaft 14, the movable shaft 14 extends into the connecting groove 3-1; the outer frame 1 is provided with a driving mechanism, the sliding block 12 is driven to move by the driving mechanism to generate relative rotation between the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3; when the wind-resistant photovoltaic power generation device is in the wind-resistant mode, the folding photovoltaic panel unit is in the superimposed state, at this time, any one of the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 covers the light-receiving surface of the other photovoltaic panel assembly.

[0031] In the present application, in the normal working mode, the folding photovoltaic panel unit is in the unfolded state, at this time, the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 in the folding photovoltaic panel unit are in the coplanar state, so that the first photovoltaic panel assembly 2 and the second photovoltaic panel can receive sunlight to the greatest extent, and the power generation efficiency is improved. When facing strong wind weather, the sliding block 12 is driven to move by the driving mechanism, under the driving of the sliding block 12, the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 on the folding photovoltaic panel unit are rotated and finally reach the superimposed state, when the folding photovoltaic panel unit is in the superimposed state, the horizontal wind-receiving area of the photovoltaic panel will be greatly reduced, thereby greatly reducing the horizontal wind load borne by the entire photovoltaic power generation equipment; reducing the risk of deformation of the equipment support, damage of the photovoltaic panel and the like, and improving the wind resistance performance.

[0032] When the folded photovoltaic panel unit is in the stacked state, due to the great reduction of the unfolded area of the photovoltaic panel, the probability of the photovoltaic panel being hit by solid objects will also be greatly reduced. Moreover, in the stacked state, any one of the two photovoltaic panel assemblies covers the light-receiving surface of the other photovoltaic panel assembly, in other words, in the stacked state, the photovoltaic panel assemblies of the folded photovoltaic panel unit are all back outward and light-receiving surface inward, so that the light-receiving surface of the photovoltaic panel assembly is hidden (not exposed outward), so that the light-receiving surface of the photovoltaic panel assembly is effectively protected, even if the tree branches, garbage and other solid objects in the strong wind are hit on the photovoltaic panel assembly, they will only hit the back of the photovoltaic panel assembly, and will not directly hit the relatively fragile light-receiving surface of the photovoltaic panel assembly; and the back of the photovoltaic panel usually has a back plate with high toughness and high impact resistance, which has a much better impact resistance than the light-receiving surface of the photovoltaic panel assembly (the light-receiving side surface of the photovoltaic panel assembly is usually encapsulated by a glass material with high light transmittance, which is weak and easy to break after impact), so as to effectively resist the impact of solid objects and protect the photovoltaic panel assembly from impact damage.

[0033] The driving mechanism comprises a lead screw 5, a lead screw nut 13 arranged on the sliding block 12, the lead screw 5 is arranged on both sides of the outer frame 1, and the lead screw 5 is in threaded cooperation with the lead screw nut 13; one end of the lead screw 5 is connected with the motor 4. The sliding block 12 can move along the axial direction of the outer frame 1, and the lead screw 5 is arranged along the axial direction of the outer frame 1. The motor 4 is fixedly connected with the outer frame 1, and the motor 4 drives the lead screw 5 to rotate. When the lead screw 5 rotates, the lead screw nut 13 connected with the lead screw 5 can be driven to move, and the lead screw nut 13 drives the movable shaft 14 to move synchronously when the lead screw nut 13 moves, and the movable shaft 14 drives the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 to rotate relative to each other when the movable shaft 14 moves.

[0034] The outer frame 1 is provided with a sliding groove 1-1 on both sides, and the sliding block 12 is slidingly connected in the sliding groove 1-1. The sliding direction of the sliding block 12 is guided through the sliding groove 1-1.

[0035] The back surfaces of the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 are provided with a protective plate 20. The protective plate 20 can be made of PP composite material and can be attached to the back surfaces of the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 to improve the impact resistance of the back surfaces of the photovoltaic panel assemblies. The back surface of the photovoltaic panel refers to the side opposite to the light-receiving surface of the photovoltaic panel assembly.

[0036] Further, the connecting groove 3-1 is long and the movable shaft 14 can move between the two ends of the connecting groove 3-1; the second photovoltaic panel assembly 3 is provided with a transmission oil cylinder 15, the transmission oil cylinder 15 is located below the connecting groove 3-1, the transmission oil cylinder 15 comprises a first cylinder body, a first piston 15-2 is arranged in the first cylinder body, a first medium cavity 15-3 is formed between the first piston 15-2 and one end of the first cylinder body, and a first spring 15-4 is arranged in the first medium cavity 15-3; a piston rod 15-5 is arranged on the first piston 15-2, the piston rod 15-5 passes out from the other end of the first cylinder body, the front end of the piston rod 15-5 is in contact with the movable shaft 14; the first medium cavity 15-3 is filled with pressure transmission medium; the back of the second photovoltaic panel assembly 3 is provided with an execution oil cylinder 18, the execution oil cylinder 18 comprises a second cylinder body, a second piston 18-2 is arranged in the second cylinder body, a second medium cavity 18-3 is formed between the second piston 18-2 and one end of the second cylinder body, and a second spring 18-4 is arranged between the second piston 18-2 and the other end of the second cylinder body; a top rod 18-5 is arranged on the second piston 18-2 and passes out from the second cylinder body; the first cylinder body and the second cylinder body are connected through a connecting pipe 17, the connecting pipe 17 connects the first medium cavity 15-3 and the second medium cavity 18-3; the back of the first photovoltaic panel assembly 2 is fixedly provided with a pushed plate 19, and the pushed plate 19 is arranged correspondingly to the execution oil cylinder 18; when the top rod 18-5 on the execution oil cylinder 18 extends, a pushing force is applied to the pushed plate 19 to make the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 relatively rotate.

[0037] When the folding photovoltaic panel unit is switched from the unfolded state to the folded state, at the initial stage of driving, since the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 are in the same straight line, and the direction of the force applied by the movable shaft 14 to the second photovoltaic panel assembly 3 will pass through the rotation center of the second photovoltaic panel assembly 3, at this time, the force generated by the movable shaft 14 cannot generate a rotation torque on the second photovoltaic panel assembly 3, and the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 will generate a "rotation dead point" that cannot be rotated. In order to pass through this "rotation dead point", the transmission oil cylinder 15 and the driving oil cylinder are arranged to solve the problem of the "rotation dead point".

[0038] When the folding photovoltaic panel unit is switched from the unfolded state to the folded state, the driving mechanism first drives the slider 12 to move axially downward relative to the outer frame 1. The movable shaft 14 on the slider 12 first moves a certain distance in the connecting groove 3-1. In this process, the second photovoltaic panel unit cannot rotate due to being at a "rotational dead point". When the movable shaft 14 moves in the connecting groove 3-1, it exerts pressure on the piston rod 15-5 of the transmission oil cylinder 15 and drives it to move downward. At this time, the transmission oil cylinder 15 starts to work. With the continuous movement of the slider 12, the piston rod 15-5 pushes the first piston 15-2 to move into the first cylinder body, compressing the transmission medium in the first medium cavity 15-3. The transmission medium transmits pressure to the second medium cavity 18-3 through the connecting pipe 17, pushing the second piston 18-2 to move, and then making the top rod 18-5 of the execution oil cylinder 18 extend outward. After the top rod 18-5 extends, it exerts a pushing force on the pushed plate 19 on the back of the first photovoltaic panel assembly 2. This pushing force can cause the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 to rotate relative to each other, making them rotate at a certain angle and changing their state of being on the same straight line. Thus, it helps the folding photovoltaic panel unit to pass through the "rotational dead point". The whole process is shown in FIG. 8. Figure 8 After passing through the "rotational dead point", the force generated by the movable shaft 14 can generate a rotational torque on the second photovoltaic panel assembly 3, continuing to push the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3 to rotate relative to each other until reaching the folded state.

[0039] The present application utilizes the hydraulic transmission principle to convert the linear motion of the movable shaft 14 into the pushing force of the top rod 18-5 on the pushed plate 19 through the cooperative work of the transmission oil cylinder 15 and the execution oil cylinder 18, providing additional rotational power for the first photovoltaic panel assembly 2 and the second photovoltaic panel assembly 3, so that the device can smoothly pass through the "rotational dead point" and realize the switching of the folding photovoltaic panel unit from the unfolded state to the folded state. This design ensures that the folding photovoltaic panel unit can reliably perform unfolding and folding operations in various situations, improving the overall reliability and stability of the wind-resistant photovoltaic power generation device, allowing it to better protect the photovoltaic panel assembly in the wind-resistant mode and reduce equipment damage caused by extreme weather such as strong winds. The structural design of the transmission oil cylinder 15 and the execution oil cylinder 18 is compact, and through hydraulic transmission, it can efficiently transmit force and motion. The hydraulic system has the characteristics of fast response speed and high control precision, which can accurately control the rotation of the folding photovoltaic panel unit, and is also convenient for integration and installation with other components.

[0040] In this embodiment, the transmission medium is hydraulic oil.

[0041] The application further comprises a movable support frame 7, both ends of the outer frame 1 are respectively provided with guide rails 8, both ends of the movable support frame 7 are respectively connected with the guide rails 8 at both ends of the outer frame 1 in a sliding mode; the outer frame 1 is provided with a driving member 9 for driving the movable support frame 7 to move horizontally; the movable support frame 7 is provided with support components 10 corresponding to the folded photovoltaic panel unit; when the wind-resistant photovoltaic power generation device is in the wind-resistant mode, the movable support frame 7 is driven to move to the support position by the driving member 9 so that the pushed plate 19 on the second photovoltaic panel assembly 3 is clamped into the support component 10.

[0042] When the wind-resistant photovoltaic power generation device is in the wind-resistant mode, the movable support frame 7 is driven to move horizontally along the guide rails 8 at both ends of the outer frame 1 to the support position by the driving member 9, so that the pushed plate 19 on the second photovoltaic panel assembly 3 is clamped into the support component 10. In this way, the movable support frame 7 can provide additional support force for the folded photovoltaic panel unit, effectively enhancing the stability of the device in adverse weather conditions such as strong wind, reducing the possibility of shaking, displacement or even damage of the photovoltaic panel assembly due to wind force, thereby improving the wind resistance of the entire photovoltaic power generation device. The use of the movable support frame 7 and the support component 10 can firmly fix the folded photovoltaic panel unit in the wind-resistant mode, avoiding relative rotation or collision between the photovoltaic panel assemblies, thereby protecting the light-receiving surface and other components of the photovoltaic panel assembly from damage, prolonging the service life of the photovoltaic panel assembly and reducing maintenance costs.

[0043] Among them, the setting of the guide rail 8 provides accurate guidance for the movement of the movable support frame 7, ensuring that the movable support frame 7 can accurately move to the support position, so that the pushed plate 19 can be accurately clamped into the support component 10, realizing reliable fixation of the folded photovoltaic panel unit.

[0044] Among them, the support component 10 comprises two oppositely arranged clamping plates, and a clamping groove for accommodating the pushed plate 19 is formed between the two clamping plates.

[0045] In this embodiment, the driving member 9 is an electric push rod.
