Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the relative positions of the corresponding components in the direction of gravity when they are in use; "inner" and "outer" generally refer to the relative positions of the corresponding components with respect to their own contours; and terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0026] Based on the specific embodiments provided in this disclosure, refer to Figures 1 to 5 As shown, a photovoltaic panel protection device is provided, including a fixed bracket 1, a translation mechanism 2, and a protective cover 3. The fixed bracket 1 is used to install a photovoltaic panel 4, and the protective cover 3 is installed on the fixed bracket 1 in an adjustable position via the translation mechanism 2. The translation mechanism 2 is used to drive the protective cover 3 to switch between a first position and a second position relative to the fixed bracket 1: in the first position, the protective cover 3 is away from the photovoltaic panel 4 so that the photovoltaic panel 4 is exposed; in the second position, the protective cover 3 is placed over the photovoltaic panel 4.

[0027] Through the above technical solution, in the photovoltaic panel protection device provided in this disclosure, the fixed bracket 1 is used to install the photovoltaic panel 4, and the protective cover 3 is movably installed on the fixed bracket 1 through the translation mechanism 2. In this way, the movement of the protective cover 3 relative to the fixed bracket 1, i.e. the photovoltaic panel 4, can be controlled by the translation mechanism 2 to selectively expose the photovoltaic panel 4 according to whether the photovoltaic panel 4 needs to be put into use. When the photovoltaic panel 4 is put into use, the movement of the protective cover 3 is controlled to expose the photovoltaic panel 4. When the photovoltaic panel 4 is no longer in use, the protective cover 3 is controlled to cover the photovoltaic panel 4 to avoid the photovoltaic panel 4 being exposed to direct sunlight and to improve the service life of the photovoltaic panel 4.

[0028] In the photovoltaic panel protection device provided in this disclosure, the translation mechanism 2 can be constructed in any suitable form, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1 and Figure 2 As shown, the translation mechanism 2 may include a first driving device 21 and a first transmission structure 22. The first driving device 21 may be installed on one of the protective cover 3 and the fixed bracket 1, and the first driving device 21 is connected to the other of the protective cover 3 and the fixed bracket 1 through the first transmission structure 22 to drive the protective cover 3 to switch between a first position and a second position. In this disclosure, the first driving device 21 is fixed to the protective cover 3 and connected to the fixed bracket 1 through the first transmission device. In this way, the first driving device 21 drives the first transmission device, and the first transmission device drives the protective cover 3 to move, realizing the switching of the photovoltaic panel 4 between the first position and the second position.

[0029] In some other embodiments, the first driving device 21 can also be fixed to the fixed bracket 1 and connected to the protective cover 3 through the first transmission device, which can also realize the movement of the protective cover 3 relative to the fixed bracket 1. This disclosure does not make specific limitations in this regard.

[0030] The first transmission structure 22 can be constructed in any suitable form to drive the protective cover 3 to move relative to the fixed bracket 1, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1As shown, the first driving device 21 can be constructed as a linear motor 211, and the first transmission structure 22 can be constructed as a telescopic rod 221. The linear motor 211 is fixed to the fixed bracket 1, one end of the telescopic rod 221 is connected to the output shaft of the linear motor 211, and the other end of the telescopic rod 221 is connected to the outside of the protective cover 3. In this way, the linear motor 211 drives the free end of the telescopic rod 221 to move through the output shaft, thereby adjusting the length of the telescopic rod 221. Since the free end of the telescopic rod 221 is fixed to the protective cover 3, the distance between the protective cover 3 and the fixed end of the telescopic rod 221 relative to the free end can be adjusted. The fixed end is fixed to the fixed bracket 1, which also allows for the adjustment of the distance between the protective cover 3 and the fixed bracket 1, ultimately achieving the switching of the position of the protective cover 3 relative to the fixed bracket 1.

[0031] In some other embodiments, the first driving device 21 can also be constructed as a cylinder. In this case, the first transmission structure 22 may not be provided. The body of the cylinder can be fixed to one of the protective cover 3 and the fixed bracket 1, and the piston rod of the cylinder can be connected to the other of the protective cover 3 and the fixed bracket 1. In this way, the working piston rod of the cylinder can perform linear reciprocating motion, thereby realizing the switching of the protective cover 3 between the first position and the second position. This disclosure does not impose any specific limitations on this.

[0032] In the photovoltaic panel protection device provided in this disclosure, as an exemplary embodiment, the translation mechanism 2 may include a roller 23. The roller 23 may be installed inside the protective cover 3. The fixed bracket 1 may have a slide rail 11 that cooperates with the roller 23. The slide rail 11 and the telescopic rod 221 are arranged parallel to each other, and the roller 23 makes rolling contact with the slide rail 11. The roller 23 is movably connected inside the slide rail 11. Since the roller 23 is installed inside the protective cover 3 and the slide rail 11 is parallel to the telescopic rod 221, when the protective cover 3 moves along the direction of movement of the telescopic rod 221 to switch between a first position and a second position, the roller 23 moves inside the slide rail 11 under the drive of the protective cover 3. The arrangement of the roller 23 can provide a certain support for the protective cover 3 while minimizing the friction between the protective cover 3 and the fixed bracket 1, thereby improving the reliability of the movement of the protective cover 3.

[0033] In the photovoltaic panel protection device provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 1 and Figure 2As shown, the photovoltaic panel protection device may include a rotating mechanism 5 and a movable support 6. The rotating mechanism 5 may be mounted on a fixed support 1, and the movable support 6 may be connected to the fixed support 1 via the rotating mechanism 5. The movable support 6 is used to mount the photovoltaic panel 4, and the rotating mechanism 5 is used to drive the movable support 6 to move so that the movable support 6 forms an angle with respect to the fixed support 1. That is, the photovoltaic panel 4 is fixed to the movable support 6 and movably connected to the fixed support 1 via the rotating mechanism 5. When the rotating mechanism 5 drives the movable support 6 to move relative to the fixed support 1, the photovoltaic panel 4 can move relative to the fixed support 1, so that the photovoltaic panel 4 forms an angle with the fixed support 1. In this way, during actual use, the angle of the photovoltaic panel 4 can be adjusted according to different solar angles, so that the photovoltaic panel 4 can remain within the solar irradiation angle range at different times of the year and in different seasons, thereby improving the energy output of the photovoltaic panel 4.

[0034] In the photovoltaic panel protection device provided in this disclosure, the rotating mechanism 5 can be constructed in any suitable form, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1 and Figure 2 As shown, the rotating mechanism 5 may include a second driving device 51, a second transmission structure 52, and a connecting rod 53. One end of the connecting rod 53 may be hinged to the fixed bracket 1, and the other end may be hinged to the movable bracket 6. The second driving device 51 may be installed on the fixed bracket 1 and transmitted to the movable bracket 6 through the second transmission structure 52. The second driving device 51 drives the rotating mechanism 5 to work, thereby causing the movable bracket 6, i.e., the photovoltaic panel 4, to translate relative to the fixed bracket 1. One end of the connecting rod 53 is hinged to the movable bracket 6, and the other end is hinged to the fixed bracket 1, so that while the movable bracket 6 is translating relative to the fixed bracket 1, it can also drive the movable bracket 6 to rotate relative to the fixed bracket 1, ultimately achieving the adjustment of the angle of the movable bracket 6.

[0035] The second transmission structure 52 can be constructed in any suitable form to adjust the angle of the movable support 6, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 2 As shown, the second drive device 51 can be configured as a rotary motor 511, and the second transmission structure 52 can include a lead screw 521 and a nut 522 that cooperate with each other. The lead screw 521 is connected to the output shaft of the rotary motor 511, and the nut 522 is connected to the movable bracket 6. In this way, the rotary motor 511 works and drives the lead screw 521 to rotate through the output shaft. The nut 522 cooperates with the lead screw 521 to move along the axial direction of the lead screw 521. Since the movable bracket 6 is connected to the nut 522, the movable bracket 6 can move along the axial direction of the lead screw 521. Thus, with the joint cooperation of the second transmission structure 52 and the connecting rod 53, the angle of the movable bracket 6 relative to the fixed bracket 1 can be adjusted.

[0036] In the photovoltaic panel protection device provided in this disclosure, the movable support 6 can be constructed in any suitable form, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 1 and Figure 2 As shown, the movable support 6 may include a first mounting base 61 and a frame body 62. The first mounting base 61 may be fixed to the nut 522, and the frame body 62 is rotatably connected to the first mounting base 61 and is used to mount the photovoltaic panel 4. The first mounting base 61 restricts the nut 522 from rotating circumferentially along the lead screw 521 under its drive, ultimately achieving the purpose of moving the nut 522 and the first mounting base 61 axially along the lead screw 521. The first mounting base 61 also provides a carrier for the installation of the frame body 62, i.e., the photovoltaic panel 4, enabling the photovoltaic panel 4 to move axially along the lead screw 521.

[0037] The frame body 62 can be rotatably connected to the first mounting base 61 in any suitable form, and this disclosure does not impose specific limitations in this regard. As an exemplary embodiment, refer to... Figure 1 or Figure 2 As shown, the movable support 6 may further include a first rotating shaft 63, which is rotatably supported on a first mounting base 61. Both ends of the first rotating shaft 63 are respectively hinged to hinge seats 631, which are slidably connected to the fixed support 1. The frame body 62 can be hinged to the hinge seats 631. The frame body 62 is rotatably connected to the first mounting base 61 via the first rotating shaft 63. Through the cooperation of the first rotating shaft 63 and the hinge seats 631, it can rotate relative to the fixed support 1 while being slidably connected to it. Thus, the first rotating shaft 63 moves axially along the lead screw 521 under the drive of the first mounting base 61. Under the action of the connecting rod 53, the frame body 62 moves axially along the lead screw 521 while rotating relative to the first mounting base 61, thereby adjusting the angle of the frame body 62, i.e., the photovoltaic panel 4.

[0038] In some other embodiments, the hinge seat 631 may be omitted, and the frame body 62 may be directly hinged to both ends of the first rotating shaft 63. Similarly, under the combined action of the first mounting base 61 and the connecting rod 53, the angle of the frame body 62 can be adjusted. In this disclosure, the hinge seat 631 allows the frame body 62 to be connected to the fixed support 1, improving the reliability of the frame body 62's movement. In yet another embodiment, the first rotating shaft 63 and the hinge seat 631 may be omitted, and the frame body 62 may be directly hinged to the first mounting base 61 to achieve angle adjustment. This disclosure does not impose specific limitations on this.

[0039] The connecting rod 53 can be hinged to the fixed bracket 1 in any suitable manner, and this disclosure does not impose any specific limitations on this. As an exemplary embodiment, refer to...Figure 1 or Figure 2 As shown, the movable support 6 may include a second rotating shaft 64, and the fixed support 1 may be provided with a second mounting base 12. The second rotating shaft 64 is rotatably supported on the second mounting base 12. One end of the connecting rod 53 may be hinged to the end of the second rotating shaft 64, and the other end of the connecting rod 53 may be hinged to the frame body 62. In this way, when the frame body 62 moves axially along the lead screw 521 under the drive of the first mounting base 61 and the first rotating shaft 63 and rotates relative to the fixed support 1, one end of the connecting rod 53 is hinged to the frame body 62, and the other end is hinged to the fixed support 1 through the cooperation of the second rotating shaft 64 and the second mounting base 12. This allows the angle of the frame body 62 to be adjusted according to its position and angle. Furthermore, the connecting rod 53 can also provide certain support for the frame body 62 when it moves to the desired position, facilitating the fixation of the frame body 62's position.

[0040] When in use, the photovoltaic panel protection device provided in this disclosure has the protective cover 3 in the first position (see reference). Figure 3 As shown in the diagram, the linear motor 211 is controlled to operate to push the telescopic rod 221 to extend, thereby causing the protective cover 3 to switch from the first position to the second position (see reference). Figure 4 As shown in the diagram, to expose the photovoltaic panel 4 to sunlight, the rotary motor 511 is controlled to drive the lead screw 521 to rotate, thereby causing the first mounting base 61 to move along the axial direction of the lead screw 521. Simultaneously, under the combined action of the connecting rod 53, the movable bracket 6 moves relative to the fixed bracket 1 and rotates to the desired position (see reference). Figure 5 As shown in the figure, the angle of the movable support 6, i.e. the photovoltaic panel 4, can be adjusted so that the photovoltaic panel 4 can remain within the range of solar irradiation angle at different times of different seasons, thereby improving the energy output of the photovoltaic panel 4.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
