Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a protective device for a photovoltaic solar power generation panel. Background Art

[0002] With the continuous growth of global demand for clean energy, photovoltaic solar power generation, as a green and sustainable energy utilization method, has occupied an increasingly important position in the field of electricity supply. As the core component of the photovoltaic power generation system, the normal operation of photovoltaic solar panels is directly related to the power generation efficiency and system stability. However, in actual application, photovoltaic solar panels face challenges from many natural environmental factors, especially severe weather such as strong winds and dust, which are particularly harmful to the panels. The limitations of existing protective devices are becoming increasingly prominent.

[0003] On the one hand, the traditional photovoltaic solar panel support structure has poor stability. Most panels use a fixed-angle support method. Although it can meet daily light reception needs, in windy weather, the thin support structure is difficult to withstand the impact of strong winds, which can easily cause the panels to tilt, loosen or even overturn. Not only does it cause physical damage to the panels, it may also cause circuit failures, endangering the safety of surrounding facilities and personnel. Although some protective devices are equipped with simple reinforcement structures, they lack the ability to adaptively adjust to extreme wind forces and cannot effectively protect the panels when strong winds come.

[0004] On the other hand, existing protective devices lack sufficient intelligence and automation to handle severe weather conditions. When faced with extreme weather conditions such as high winds and dust storms, manual intervention measures often lag behind and fail to respond promptly to environmental changes. For example, during a sudden strong wind, manually adjusting or securing panels is not only inefficient but also dangerous. Some automated protective devices lack a buffering design when panels fall, which can easily cause secondary damage to the photovoltaic modules on the panels' surfaces due to the excessive impact force. Furthermore, they lack follow-up protection for the panels, making it impossible to prevent the continued impact of foreign objects such as sand and gravel carried by strong winds.

[0005] To sum up, the development of a photovoltaic solar panel protection device that can effectively resist the impact of severe weather while ensuring the light receiving efficiency of the power generation panel and has adaptive adjustment and buffer protection has become an urgent need to promote the stable development of the photovoltaic power generation industry. The photovoltaic solar panel protection device of the present invention came into being based on this background. Summary of the Invention

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-11As shown, a protective device for a photovoltaic solar panel provided by an embodiment of the present invention includes a base 101 and a mounting plate 102, the upper surface of the mounting plate 102 is fixedly mounted with photovoltaic panels 103 distributed at equal distances, the upper surface of the base 101 is fixedly mounted with a fixed shaft 104, the end of the mounting plate 102 is fixedly mounted with a rotating member 105, and the rotating member 105 is rotatably sleeved on the outside of the fixed shaft 104, the upper surface of the base 101 is also fixedly mounted with symmetrically distributed first ear seats 106, and a rotating shaft 107 is rotatably mounted between the first ear seats 106, the outer wall of the rotating shaft 107 is fixedly mounted with a support plate 108, and the side wall of the support plate 108 is fixedly mounted with a U-shaped card plate 109, the lower surface of the mounting plate 102 is fixedly mounted with a support rod 110, and the end of the support rod 110 is fixedly mounted with The clamping rod 111, the end of the clamping rod 111 is located in the U-shaped clamping plate 109, and the upper surface of the base 101 is also provided with a fixing port 112 for the support rod 110 to pass through the base 101, and also includes: a pulling mechanism, the pulling mechanism is arranged between the base 101 and the mounting plate 102, and is used to apply traction to the mounting plate 102; a buffer mechanism, the buffer mechanism is arranged in the base 101, and is used to buffer the descending mounting plate 102 when the clamping rod 111 is separated from the U-shaped clamping plate 109; a locking mechanism, the locking mechanism is arranged on the surface of the base 101, and is used to lock the position of the mounting plate 102 when the mounting plate 102 is rotated to a state parallel to the base 101; a protective mechanism, the protective mechanism is arranged on the outside of the base 101, and is used to shield the photovoltaic panel 103 on the surface of the mounting plate 102 when the mounting plate 102 is flat.

[0040] By engaging the clamping rod 111 at the end of the support rod 110 in the U-shaped clamping plate 109, the support plate 108 can play a supporting role on the mounting plate 102, so that the photovoltaic panel 103 on the surface of the mounting plate 102 can be tilted to achieve the purpose of receiving sufficient light. When encountering strong winds, the traction effect of the traction mechanism can prevent the clamping rod 111 from separating from the U-shaped clamping plate 109, so as to ensure the supporting stability of the support plate 108 on the mounting plate 102. When encountering severe windy weather and the wind force is strong enough to overturn the mounting plate 102, the strong wind force will cause the mounting plate 102 to rotate, thereby causing the clamping rod 111 to move in the U-shaped clamping plate 109 until the rotation of the mounting plate 102 exceeds the traction limit of the traction mechanism, at which time the clamping rod 111 will separate from the U-shaped clamping plate 109, and the support plate 102 will be lifted. 108 automatically falls down under the action of its own gravity and remains parallel to the base 101, and the mounting plate 102 also automatically falls down and remains parallel to the base 101 under the traction of its own gravity and the pulling mechanism, and when the mounting plate 102 is laid flat, the locking mechanism can just lock the mounting plate 102, effectively preventing the mounting plate 102 from being lifted up by strong winds again. Furthermore, when the mounting plate 102 is laid down, the buffer mechanism can also play a certain buffering role, effectively preventing the mounting plate 102 from generating a large impact force when it is laid down, causing an impact on the photovoltaic panel 103 on the surface of the mounting plate 102. Furthermore, when the mounting plate 102 is laid flat, the protective mechanism can also be used to shield the photovoltaic panel 103 on the surface of the mounting plate 102, preventing foreign objects carried by strong winds from hitting the surface of the photovoltaic panel 103 and causing damage, thereby achieving better use effect.

[0041] As an embodiment of the present invention, please refer to Figure 2 、 Figure 7 and Figure 10The pulling mechanism includes a pulling cylinder 201 rotatably arranged on the upper surface of the base 101, and a movable plate 204 is movably installed in the pulling cylinder 201. The lower surface of the movable plate 204 and the bottom inner wall of the pulling cylinder 201 are connected by a first spring 203. The upper surface of the movable plate 204 is fixedly installed with a pulling rope 205 that passes through the pulling cylinder 201. In this embodiment, preferably, the outer wall of the mounting plate 102 is fixedly installed with a hanging ring, and the end of the pulling rope 205 is fixedly installed with a hook, which is hung on the hanging ring. When installing, the hook can be removed. When the clamping rod 111 is clamped in the U-shaped clamping plate 109, the hook is hung on the hanging ring, which is more convenient to install. The side wall of the mounting plate 102 is fixedly installed with a fixing frame 202 , and the end of the traction rope 205 is connected to the fixed frame 202. Under the elastic force of the first spring 203, the traction rope 205 can apply a certain pulling force to the fixed frame 202 on one side of the mounting plate 102. As strong wind acts on the mounting plate 102, the movable plate 204 will be prompted to move in the pulling cylinder 201, prompting the first spring 203 to be stretched, and the more the clamping rod 111 moves in the U-shaped clamping plate 109, the greater the amplitude of the stretching of the first spring 203, and the greater the traction force applied by the traction rope 205 to the mounting plate 102. Only when the wind force exceeds a certain value will the clamping rod 111 come out of the U-shaped clamping plate 109, effectively ensuring the stability of the mounting plate 102 under a certain wind force, and the use effect is better.

[0042] As an embodiment of the present invention, please refer to Figure 3 、 Figure 6 and Figure 8 When the lifting block 301 is lifted up, the lifting block 301 is lifted up and the support frame 302 is tightened, so that the lifting block 301 can be tightened.

[0043] As an embodiment of the present invention, please refer to Figure 3 and Figure 5The locking mechanism includes a vertical plate 401 fixedly mounted on the upper surface of the base 101, and a movable opening is opened on the outer wall of the vertical plate 401, and a locking plate 402 is movably installed in the movable opening, and a baffle 403 is fixedly mounted on one end of the locking plate 402, and an oblique chamfer 405 is opened on the other end of the locking plate 402. The baffle 403 and the vertical plate 401 are connected by a third spring 404. When the mounting plate 102 is tilted, the side of the mounting plate 102 will contact the oblique chamfer 405 at the end of the locking plate 402, causing the locking plate 402 to move in the vertical plate 401, so that the third spring 404 is stretched. Until the mounting plate 102 completely passes over the locking plate 402, the locking plate 402 is reset under the elastic force of the third spring 404, and the mounting plate 102 can be restricted to the bottom of the locking plate 402, effectively preventing the strong wind from blowing the mounting plate 102 up again, and the use effect is better.

[0044] As an embodiment of the present invention, please refer to Figure 1 、 Figure 3 and Figure 4 , the protective mechanism includes a slide 701 opened on both sides of the base 101, and a plurality of sliders 702 are slidably installed in the slide 701, a U-shaped frame 703 is fixedly installed on the outer wall of the slider 702, and adjacent U-shaped frames 703 are connected by a protective cloth 704, a stepper motor 705 is fixedly installed on the lower surface of the base 101, and the driving end of the stepper motor 705 is rotatably connected to a screw rod 706, and the outer side of the screw rod 706 is connected to a moving block 707, the slider 702 at the head end of the slide 701 and the moving block 707 are connected by a connecting rod 708, and the slider 702 at the tail end of the slide 701 is fixedly installed in the slide 701 by bolts, and the base 1 01 is also provided with a trigger unit, which is used to trigger the stepper motor 705 to drive the moving block 707 to move outside the screw rod 706 when the mounting plate 102 is placed flat. When the mounting plate 102 is placed horizontally on the surface of the base 101, the stepper motor 705 can also drive the screw rod 706 to rotate, and the screw rod 706 drives the moving block 707 to move. The moving block 707 drives the U-shaped frame 703 to move above the base 101 with the help of the connecting rod 708, so that the protective cloth 704 between the U-shaped frames 703 can be unfolded and covered above the photovoltaic panel 103, which plays the role of shielding the photovoltaic panel 103, effectively preventing foreign objects in strong winds from damaging the photovoltaic panel 103, and having a better use effect.

[0045] As an embodiment of the present invention, please refer to Figure 3 、 Figure 8 and Figure 9The trigger unit includes: a first trigger component, which is arranged below the base 101 and is used to detect whether the mounting plate 102 is in a horizontal state with the base 101; a second trigger component, which is arranged above the base 101 and is used to detect whether the support plate 108 is rotated. When the first trigger component detects that the mounting plate 102 is in a horizontal state with the base 101 and the second trigger component detects that the support plate 108 is rotating, the stepper motor 705 will be triggered to start working, effectively avoiding the stepper motor 705 from being started due to accidental touch, and the use effect is better.

[0046] As an embodiment of the present invention, please refer to Figure 8 and Figure 9 The first trigger assembly includes a rotating plate 501 arranged below the base 101, a second ear seat 502 is fixedly installed on the lower surface of the base 101, a fixing rod 503 is fixedly installed between the second ear seats 502, and the rotating plate 501 is rotatably sleeved on the outside of the fixing rod 503, the rotating plate 501 is located directly below the fixing port 112, a torsion spring 504 is sleeved on the outside of the fixing rod 503, one end of the torsion spring 504 is connected to the second ear seat 502, and the other end of the torsion spring 504 is connected to the rotating plate 501, and an inclined plate 505 is also fixedly installed on the lower surface of the base 101, and the inclined plate 505 A touch switch 506 is fixedly installed on the outer wall, which is used to contact the touch switch 506 when the rotating plate 501 rotates. When the mounting plate 102 is automatically tilted due to strong wind, the clamping rod 111 connected to the bottom of the mounting plate 102 through the support rod 110 will enter the fixing port 112 and push the rotating plate 501 to rotate, causing the torsion spring 504 on the outside of the fixing rod 503 to twist. When the mounting plate 102 remains horizontal, the rotating plate 501 just contacts the touch switch 506 on the outside of the inclined plate 505, thereby achieving the purpose of detecting whether the mounting plate 102 remains horizontal with the base 101.

[0047] As an embodiment of the present invention, please refer to Figure 3 The second trigger component includes a vertical plate 601 fixedly arranged on the upper surface of the base 101, and a mounting tube 602 is fixedly installed on the outer wall of the vertical plate 601. The end of the mounting tube 602 is in contact with the outer wall of the support plate 108, and a distance sensor 603 is fixedly installed in the mounting tube 602 to detect whether the support plate 108 is moved from the end of the mounting tube 602. When the support plate 108 rotates, and until the support plate 108 releases the obstruction of the mounting tube 602, the value detected by the distance sensor 603 in the mounting tube 602 will increase significantly, indicating that the support plate 108 has been moved from the end of the mounting tube 602, thereby achieving the purpose of detecting whether the support plate 108 has rotated, and the use effect is better.

[0048] It should be noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
