Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment protection technology, specifically to a new energy photovoltaic panel protection device. Background Technology

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy using the photoelectric effect. When sunlight shines on the surface of a photovoltaic panel, the light energy is absorbed by the photovoltaic cells and generates an electric current. However, photovoltaic panels themselves are relatively fragile and require protection.

[0003] In recent years, various protective devices for photovoltaic panels have emerged. For example, Chinese patent CN217406442U discloses a protective device for new energy photovoltaic panels. It uses anti-slip grooves and slots on the surface of the enclosure frame to slide and adjust the position of the protective plate and elastic connecting piece. The protective plate and elastic connecting piece are stretched to protect the photovoltaic panel.

[0004] However, the device still has some shortcomings in actual use. In heavy snow, the snow will cover the photovoltaic panels. When the photovoltaic panels need to be put back into use, the snow on the protective device needs to be removed before the photovoltaic panels can be exposed to sunlight and work, which increases the operation and maintenance costs and time costs. In view of this, a new energy photovoltaic panel protection device is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a protection device for new energy photovoltaic panels that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention proposes a new energy photovoltaic panel protection device, comprising a protective box, wherein the protective box is internally provided with a folding and fixing mechanism and a reinforcing support mechanism. The folding and fixing mechanism is used to fix the photovoltaic panel body, and the reinforcing support mechanism is used to strengthen the support and stability of the photovoltaic panel body. The folding and fixing mechanism is provided with a positioning mechanism. The folding and fixing mechanism includes:

[0007] A fixed plate is fixedly connected to the inner wall of the protective box. A telescopic hinge frame is hinged to the outer wall of the fixed plate. The end of the telescopic hinge frame away from the fixed plate is hinged to the outer wall of the movable plate. Rollers are installed at the bottom of the movable plate.

[0008] A connecting rod is fixedly connected to the hinge shaft of the telescopic hinge frame, and the end of the connecting rod away from the telescopic hinge frame is fixedly connected to the outer wall of the connecting block;

[0009] The electric telescopic rod is fixedly connected to the inner wall of the protective box, and the telescopic end of the electric telescopic rod is fixed to the connecting block.

[0010] Preferably, by extending the telescopic end of the electric telescopic rod, the connecting block can drive the connecting rod to move, and the telescopic hinge frame can be pushed to unfold. After the telescopic end of the electric telescopic rod retracts, the telescopic hinge frame can be folded and retracted. In this way, the photovoltaic panel body fixed on the telescopic hinge frame can be folded and unfolded, so that the device can be unfolded when needed. In the event of extreme weather such as heavy snow, multiple sets of photovoltaic panel bodies can be quickly stored in the protective box, and the movable plate can seal the opening of the protective box to achieve the protective effect of the photovoltaic panel body. It is also very convenient to use the photovoltaic panel body in the future.

[0011] Preferably, the reinforcing support mechanism includes a multi-stage telescopic rod, the sleeve end of which is fixedly connected to the inner wall of the protective box. A connecting plate is fixedly connected to the outer wall of each telescopic end of the multi-stage telescopic rod. A round rod one is fixedly connected to the outer wall of one set of connecting plates, and round rod two is fixedly connected to the outer wall of the other sets of connecting plates.

[0012] Preferably, the number of telescopic parts of the multi-stage telescopic rod matches the telescopic hinge frame, the first round rod is fixed to the connecting block, and the second round rod is fixed to the hinge shaft of the telescopic hinge frame.

[0013] Preferably, during the unfolding and retraction of the telescopic hinge frame, each telescopic end of the multi-stage telescopic rod will extend or retract, and the second round rod can strengthen the support at the hinge axis of the telescopic hinge frame. In this way, the stability of the telescopic hinge frame during unfolding and folding can be guaranteed, the strength of the telescopic hinge frame can be improved, and the telescopic hinge frame can effectively support multiple photovoltaic panel bodies, preventing the telescopic hinge frame from deforming and being damaged due to the large weight of multiple photovoltaic panel bodies.

[0014] Preferably, an elastic telescopic rod is fixedly connected to the outer wall of the connecting plate where the round rod is located, and an elastic protrusion is fixedly connected to the telescopic end of the elastic telescopic rod.

[0015] Preferably, a hemispherical block is fixedly connected to the inner wall of the protective box. Multiple sets of hemispherical blocks are arranged in an equidistant array. The hemispherical blocks and the elastic protrusion are on the same horizontal plane. During the extension and retraction of the multi-stage telescopic rod, the elastic protrusion is compressed by the hemispherical blocks, causing the telescopic end of the elastic telescopic rod to contract. After the elastic protrusion passes through the hemispherical blocks, the telescopic end of the elastic telescopic rod returns to its original length. The bottom inner wall of the protective box is inclined. During the folding process of the telescopic hinge frame, the photovoltaic panel body gradually tilts, causing impurities on the photovoltaic panel body to gradually slide off. Some of these impurities will remain in the protective box. As the elastic protrusion passes through the hemispherical blocks, the elastic telescopic rod can cause the elastic protrusion to strike and vibrate against the inner wall of the protective box, allowing the impurities that have fallen into the protective box to be discharged.

[0016] Preferably, the positioning mechanism includes a first hinge rod and a second hinge rod. One end of the first hinge rod and the second hinge rod are hinged to the rod body of the telescopic hinge frame. The other end of the first hinge rod and the second hinge rod are rotatably connected to a crossbar. The crossbar is sleeved by a sleeve rod. A rack rod is fixedly connected to the outer wall of the sleeve rod. The rack rod meshes with a gear. The gear is penetrated by a rotating rod and fixedly connected to the rotating rod. Multiple sets of swing rods are fixedly connected to the rotating rod. A positioning plate is hinged to the bottom of the swing rod. By unfolding the telescopic hinge frame, the movement of the telescopic hinge frame can drive the first hinge rod and the second hinge rod to move.

[0017] Preferably, the outer wall of the movable plate has a guide rail, the rack is slidably connected to the guide rail, and the rotating rod is rotatably connected to the inner wall of the movable plate. The use of the guide rail can ensure the stability of the rack's movement.

[0018] Preferably, during the unfolding process, the telescopic hinge frame drives hinge rod one and hinge rod two to move, the sleeve rod drives the rack rod to move to the left, and the gear rotates clockwise, so that the swing rod drives the positioning plate to fall and press against the ground. After the positioning plate presses against the ground, the moving plate can be stably positioned, increasing the stability of the moving plate.

[0019] This invention provides a protection device for new energy photovoltaic panels. It has the following beneficial effects:

[0020] (1) The new energy photovoltaic panel protection device uses a folding and fixing mechanism. Its electric telescopic rod drives the telescopic hinge frame to fold and unfold, so that the photovoltaic panel body can be quickly unfolded when needed. In extreme weather such as heavy snow, it can be quickly stored in the protection box. The moving plate can seal the opening of the protection box to achieve the protection effect of the photovoltaic panel body. It is also very convenient to use the photovoltaic panel body in the future.

[0021] (2) The new energy photovoltaic panel protection equipment strengthens the use of the support mechanism. The multi-stage telescopic rod and its connected round rod one and round rod two provide strong support for the telescopic hinge frame. This design ensures the stability of the telescopic hinge frame during the unfolding and folding process, effectively preventing deformation and damage caused by the large weight of the photovoltaic panel body, thereby extending the service life of the equipment.

[0022] (3) The new energy photovoltaic panel protection device uses the elastic telescopic rod and the elastic protrusion in conjunction with the hemispherical block. During the folding process of the telescopic hinge frame, the photovoltaic panel body will gradually tilt, and the impurities on the photovoltaic panel body will gradually slide off. Some of the impurities will be stored in the protection box. During the process of the elastic protrusion passing through the hemispherical block, the elastic telescopic rod can drive the elastic protrusion to knock and vibrate the inner wall of the protection box, effectively discharging the impurities that fall into the protection box.

[0023] (4) The new energy photovoltaic panel protection device uses a positioning mechanism in which components such as hinge rod one, hinge rod two, rack rod, gear and positioning plate work together to achieve stable positioning of the moving panel. When the telescopic hinge frame is unfolded, the positioning plate can automatically fall to the ground and press against it, thereby increasing the stability of the moving panel and preventing movement or tilting caused by external factors such as wind.

[0037] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-10 This invention proposes a new energy photovoltaic panel protection device, including a protection box 1. The protection box 1 is equipped with a folding and fixing mechanism 2 and a reinforcing support mechanism 4. The folding and fixing mechanism 2 is used to fix the photovoltaic panel body 3, and the reinforcing support mechanism 4 is used to strengthen the support and stability of the photovoltaic panel body 3. The folding and fixing mechanism 2 is equipped with a positioning mechanism 5.

[0040] In an embodiment of the present invention, in order to facilitate the protection of the photovoltaic panel body 3 and the use of the photovoltaic panel body 3, specifically, the folding and fixing mechanism 2 includes a fixing plate 21, a connecting rod 24, and an electric telescopic rod 26. The fixing plate 21 is fixedly connected to the inner wall of the protective box 1. A telescopic hinge frame 22 is hinged to the outer wall of the fixing plate 21. The end of the telescopic hinge frame 22 away from the fixing plate 21 is hinged to the outer wall of the moving plate 23. Rollers are installed at the bottom of the moving plate 23. The connecting rod 24 is fixedly connected to the hinge shaft of the telescopic hinge frame 22. The end of the connecting rod 24 away from the telescopic hinge frame 22 is fixedly connected to the outer wall of the connecting block 25. The sleeve part of the electric telescopic rod 26 is fixedly connected to the inner wall of the protective box 1. The telescopic end of the telescopic rod 26 is fixed to the connecting block 25. As the telescopic end of the electric telescopic rod 26 extends, the connecting block 25 can drive the connecting rod 24 to move, and the telescopic hinge frame 22 can be pushed to unfold. After the telescopic end of the electric telescopic rod 26 retracts, the telescopic hinge frame 22 can be folded and retracted. In this way, the photovoltaic panel body 3 fixed on the telescopic hinge frame 22 can be folded and unfolded, so that the device can be unfolded when needed. In the event of extreme weather such as heavy snow, multiple sets of photovoltaic panel bodies 3 can be quickly stored in the protective box 1, and the moving plate 23 can seal the opening of the protective box 1 to achieve the protective effect of the photovoltaic panel body 3. It is also very convenient to use the photovoltaic panel body 3 in the future.

[0041] Furthermore, to enhance the stability of the folding and fixing mechanism 2 during use, the supporting mechanism 4 specifically includes a multi-stage telescopic rod 41. The sleeve of the multi-stage telescopic rod 41 is fixedly connected to the inner wall of the protective box 1. A connecting plate 42 is fixedly connected to the outer wall of each telescopic end of the multi-stage telescopic rod 41. A round rod 44 is fixedly connected to the outer wall of one set of connecting plates 42, and round rods 43 are fixedly connected to the outer walls of other sets of connecting plates 42. The number of telescopic parts of the multi-stage telescopic rod 41 matches the telescopic hinge frame 22. The round rod 44 is fixed to the connecting block 25, and the round rod 43 is fixed to the hinge shaft of the telescopic hinge frame 22. During the unfolding and retraction of the telescopic hinge frame 22, each telescopic end of the multi-stage telescopic rod 41 will extend or retract. The round rod 43 can strengthen the support at the hinge axis of the telescopic hinge frame 22. In this way, the stability of the telescopic hinge frame 22 during unfolding and folding can be guaranteed, the strength of the telescopic hinge frame 22 can be improved, and the telescopic hinge frame 22 can effectively support multiple photovoltaic panel bodies 3. This design ensures the stability of the telescopic hinge frame 22 during unfolding and folding, effectively prevents deformation and damage caused by the large weight of the photovoltaic panel body 3, and thus extends the service life of the equipment.

[0042] Furthermore, an elastic telescopic rod 421 is fixedly connected to the outer wall of the connecting plate 42 where the round rod 44 is located. An elastic protrusion 422 is fixedly connected to the telescopic end of the elastic telescopic rod 421. A hemispherical block 101 is fixedly connected to the inner wall of the protective box 1. Multiple sets of hemispherical blocks 101 are arranged in an equidistant array. The hemispherical blocks 101 and the elastic protrusion 422 are on the same horizontal plane. During the telescopic process of the multi-stage telescopic rod 41, the elastic protrusion 422 is compressed by the hemispherical block 101, causing the telescopic end of the elastic telescopic rod 421 to contract. After the protrusion 422 passes through the hemispherical block 101, the telescopic end of the elastic telescopic rod 421 returns to its original length and extends. The bottom inner wall of the protective box 1 is inclined. During the folding process of the telescopic hinge frame 22, the photovoltaic panel body 3 will gradually tilt, and the impurities on the photovoltaic panel body 3 will gradually slide off. Some of these impurities will remain in the protective box 1. As the elastic protrusion 422 passes through the hemispherical block 101, the elastic telescopic rod 421 can drive the elastic protrusion 422 to knock and vibrate the inner wall of the protective box 1, so that the impurities that fall into the protective box 1 can be discharged from the protective box 1.

[0043] In an embodiment of the present invention, in order to improve the stability of the movable plate 23 during unfolding and thus ensure the stable use of the device, the positioning mechanism 5 specifically includes a first hinge rod 51 and a second hinge rod 52. One end of the first hinge rod 51 and the second hinge rod 52 are hinged to the rod body of the telescopic hinge frame 22, and the other end of the first hinge rod 51 and the second hinge rod 52 are rotatably connected to the crossbar 53. The crossbar 53 is sleeved by a sleeve rod 54, and a rack rod 55 is fixedly connected to the outer wall of the sleeve rod 54. The rack rod 55 meshes with a gear 57, and the gear 57 is penetrated by a rotating rod 58 and fixedly connected to the rotating rod 58. Multiple sets of swing rods 59 are fixedly connected to the rotating rod 58. A positioning plate 510 is hinged to the bottom of the movable plate 23. A guide rail 56 is mounted on the outer wall of the movable plate 23. A rack rod 55 is slidably connected to the guide rail 56. A rotating rod 58 is rotatably connected to the inner wall of the movable plate 23. By unfolding the telescopic hinge frame 22, the movement of the telescopic hinge frame 22 can drive the first hinge rod 51 and the second hinge rod 52 to move. The sleeve rod 54 drives the rack rod 55 to move to the left, and the gear 57 rotates clockwise, causing the swing rod 59 to drive the positioning plate 510 to fall and press against the ground, thus achieving stable positioning of the movable plate 23. This increases the stability of the movable plate 23, prevents movement or tilting caused by external factors such as wind, and ensures the effectiveness of the device.

[0044] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0045] In use, the electric telescopic rod 26 is activated first. The telescopic end of the electric telescopic rod 26 extends, and the connecting block 25 can drive the connecting rod 24 to move. The telescopic hinge frame 22 can be pushed to unfold, and the moving plate 23 moves by the rollers at the bottom. During this process, under the action of the first round rod 44 and the second round rod 43, each telescopic end of the multi-stage telescopic rod 41 will extend. The second round rod 43 can strengthen the support at the hinge axis of the telescopic hinge frame 22. In this way, the stability of the telescopic hinge frame 22 when unfolding and folding can be guaranteed, the strength of the telescopic hinge frame 22 can be improved, and the telescopic hinge frame 22 can effectively support multiple photovoltaic panel bodies 3.

[0046] Meanwhile, as the telescopic end of the electric telescopic rod 26 extends to its longest end, the telescopic hinge frame 22 moves, which can drive the hinge rod 1 51 and the hinge rod 2 52 to move. The sleeve rod 54 drives the rack rod 55 to move to the left, and the gear 57 rotates clockwise, causing the swing rod 59 to drive the positioning plate 510 to fall and press against the ground, thus achieving stable positioning of the moving plate 23.

[0047] Meanwhile, during heavy snow, by activating the electric telescopic rod 26, the telescopic end of the electric telescopic rod 26 retracts, and the moving plate 23 moves by the rollers at the bottom. During this process, under the action of the first round rod 44 and the second round rod 43, each telescopic end of the multi-stage telescopic rod 41 will retract, and the gear 57 will rotate counterclockwise, causing the swing rod 59 to drive the positioning plate 510 to rotate. The positioning plate 510 moves away from the ground. During the retraction of the telescopic hinge frame 22, the photovoltaic panel body 3 will gradually tilt, and impurities on the photovoltaic panel body 3 will gradually slide off. Some of these impurities will remain in the protective box 1. As the elastic protrusion 422 passes through the hemispherical block 101, the elastic telescopic rod 421 can drive the elastic protrusion 422 to knock and vibrate the inner wall of the protective box 1, so that the impurities that fall into the protective box 1 can be discharged from the protective box 1.
