[0049] Embodiment 1

[0050] This embodiment provides a cover plate assembly 1, which is used to cover the opening of a processing tank 2 of a photovoltaic cell sheet.

[0051] Please refer to Figures 1 to 3 Specifically, the cover plate assembly 1 includes a first cover plate 10, a second cover plate 20 and a first stopper 31; the first cover plate 10 has a first end and a second end that are arranged opposite to each other, and the first end is rotatably connected to the first supporting component; the second cover plate 20 has a third end and a fourth end that are arranged opposite to each other, and the third end is hinged to the second end so that the second cover plate 20 and the first cover plate 10 can be folded along the hinge; the first stopper 31 is arranged on the first cover plate 10 or the second cover plate 20; when the second cover plate 20 and the first cover plate 10 are folded along the hinge, the second cover plate 20 abuts against the first cover plate 10 through the first stopper 31 to limit the folding angle between the second cover plate 20 and the first cover plate 10 along the hinge.

[0052] It should be noted that the first supporting member may be a frame, a wall of the processing tank 2 or a dedicated supporting structure, all of which can be rotatably connected to the first end of the first cover plate 10, and no specific limitation is made here.

[0053] The cover plate assembly 1 in the present embodiment greatly reduces the space occupied by the cover plate assembly 1 and improves the space utilization rate of the cover plate assembly 1 by dividing the cover plate assembly 1 into a first cover plate 10 and a second cover plate 20, and the first cover plate 10 and the second cover plate 20 are foldable along the hinge. In addition, by providing a first stopper 31 on the first cover plate 10 or the second cover plate 20, the rotation angle of the cover plate assembly 1 during the folding process is limited, thereby avoiding the cover plate assembly 1 from being folded too much, thereby avoiding the cover plate assembly 1 from being stuck and colliding, and improving the service life of the cover plate assembly 1.

[0054] Optionally, the length from the first end to the second end is greater than the length from the third end to the fourth end, so that the first cover plate 10 also has a portion rotatably connected to the first supporting component. At the same time, such an arrangement also allows the first cover plate 10 to bear the weight of the second cover plate 20 when in a folded state, thereby avoiding the safety issue of the entire cover plate assembly 1 falling due to the second cover plate 20 being heavier than the first cover plate 10 and causing the first cover plate 10 to have a poor supporting effect, thereby improving the safety of the cover plate assembly 1.

[0055] Please refer to Figure 1 In some embodiments, a plurality of hinges 80 are provided between the first cover plate 10 and the second cover plate 20, and the hinges 80 are used to realize the hinge connection between the two. Optionally, the hinges 80 are hinge structures, which can realize the hinge connection between the first cover plate 10 and the second cover plate 20.

[0056] In this embodiment, the cover plate assembly 1 has not only a folded state but also an unfolded state to realize the opening of the processing tank 2 .

[0057] Specifically, when the second cover plate 20 and the first cover plate 10 are unfolded along the hinge, the second cover plate 20 and the first cover plate 10 cover the opening of the processing tank 2 to cover the processing tank 2, thereby realizing the function of the cover plate assembly 1 to open or close the processing tank 2.

[0058] Please refer to Figure 3 More specifically, the rotation stroke of the first cover plate 10 has a first stop point and a second stop point; when the first cover plate 10 is located at the first stop point, the second cover plate 20 abuts against the first cover plate 10 through the first stop member 31, and at this time, the folding between the first cover plate 10 and the second cover plate 20 is completed; when the first cover plate 10 is located at the second stop point, the second cover plate 20 and the first cover plate 10 are unfolded along the hinge, so that the second cover plate 20 and the first cover plate 10 cover the opening of the processing tank 2, so as to facilitate the opening and closing of the processing tank 2.

[0059] Please refer to Figures 4 to 6In some embodiments, the cover plate assembly 1 also includes a second stop member 32 for limiting the rotation of the first cover plate 10, so as to limit the first cover plate 10 to a first stop point, that is, to limit the folded state of the first cover plate 10, thereby avoiding excessive folding of the first cover plate 10 relative to the first support component, thereby avoiding the occurrence of collision between the first cover plate 10 and the first support component.

[0060] In some embodiments, the cover plate assembly 1 also includes a third stop member 33 for limiting the rotation of the first cover plate 10, so as to limit the first cover plate 10 to the second stop point, that is, to limit the unfolded state of the first cover plate 10, thereby avoiding excessive unfolding between the first cover plate 10 and the second cover plate 20, and thereby avoiding the occurrence of a jamming phenomenon between the first cover plate 10 and the second cover plate 20.

[0061] Since the cover assembly 1 is relatively large, the provision of a first stopper 31, a second stopper 32 and / or a third stopper 33 may cause the failure of their stop and limit functions. Therefore, optionally, a plurality of first stoppers 31, second stoppers 32 and / or third stoppers 33 are provided at intervals to ensure the effectiveness of the stop and limit functions of the first stopper 31, second stopper 32 and third stopper 33. It is understandable that the number of the first stoppers 31, second stoppers 32 and third stoppers 33 can be adaptively changed according to the size of the cover assembly 1, and is not specifically limited here.

[0062] In some embodiments, the first cover plate 10 rotates from the second stop point to the first stop point at an angle A, 90°<A≤145°. That is, when the cover plate assembly 1 is folded, the rotation angle of the first cover plate 10 is between 90° and 145°, and the opening of the cover plate assembly 1 to the processing tank 2 can be fully opened.

[0063] Optionally, 92°≤A≤105° is the optimal value for the rotation of the first cover plate 10 when the cover plate assembly 1 is folded. Within this range, the opening of the processing tank 2 can be fully opened without causing excessive interference between the cover plate assembly 1 and the surrounding space, thereby avoiding affecting the surrounding structure.

[0064] Please refer to Figure 6 In some embodiments, an elastic member 40 is further provided between the first cover plate 10 and the second cover plate 20, and the elastic member 40 is configured to be stretched as the cover plate assembly 1 is unfolded, or reset as the cover plate assembly 1 is folded; wherein, the unfolding of the cover plate assembly 1 refers to the unfolding of the second cover plate 20 and the first cover plate 10 along the hinge; and the folding of the cover plate assembly 1 refers to the folding of the second cover plate 20 and the first cover plate 10 along the hinge. This arrangement further avoids the occurrence of the first cover plate 10 and the second cover plate 20 being stuck, and at the same time provides assistance when the cover plate assembly 1 is folded, so as to facilitate the folding of the cover plate assembly 1.

[0065] Please refer to Figure 2and Figure 6 In this embodiment, the first end is rotatably connected to the first supporting component with the cover plate rotating shaft 60 as the rotating shaft to achieve a rotatable connection between the first end and the first supporting component.

[0066] In some embodiments, the cover assembly 1 further includes a driving assembly 50, which includes a connecting rod structure 52 and a driving member 51, one end of the connecting rod structure 52 is fixedly connected to the cover shaft 60; the driving member 51 includes a fixed end 511 and a movable end 512, either of which is hinged to the second support component, and the other of which is hinged to the other end of the connecting rod structure 52, so as to drive the cover shaft 60 to rotate and drive the first cover 10 to rotate, thereby realizing the folding or unfolding of the cover assembly 1. When in use, the driving member 51 drives the connecting rod structure 52 to drive the first cover 10 to rotate, thereby driving the second cover 20 to rotate, so as to realize the unfolding and folding of the cover assembly 1.

[0067] Specifically, the driving member 51 is a cylinder, which has a large output force, strong adaptability and is easy to maintain.

[0068] It should be noted that the second supporting component can be a frame, a wall of the processing tank 2 or a dedicated supporting structure; and the second supporting component is different from the first supporting component, and its specific structure is not specifically limited here.

[0069] Optionally, the driving member 51 is vertically installed on the second supporting component, which occupies a small space and can use gravity to reset the driving member 51, thereby reducing the energy consumption of the driving member 51 when the cover assembly 1 is folded.

[0070] In this embodiment, the first supporting member and the second supporting member are both disposed on the processing tank 2 to achieve the connection between the cover plate assembly 1 and the processing tank 2 .

[0071] Please refer back to Figure 1 In some embodiments, a slide plate 201 is provided at the opening of the processing tank 2, and a pulley 70 is provided on the fourth end of the second cover plate 20, so that during the folding or unfolding of the cover plate assembly 1, the fourth end of the second cover plate 20 can be slidably connected to the slide plate 201, thereby realizing convenient opening and closing of the cover plate assembly 1.

[0072] In some embodiments, the slide surface of the slide plate 201 is a plane, and the pulley 70 is a directional wheel, which is slidably connected to the slide surface. This is because the processing tank 2 is often in a high temperature state. If a slide groove is set on the tank wall of the processing tank 2, the slide groove may be deformed under high temperature conditions to block the sliding track of the pulley 70, which may cause the pulley 70 to be unable to slide; the slide surface of the slide plate 201 is set as a plane, so there is no need to worry about the problem of heat deformation affecting the sliding track of the pulley 70, which improves the reliability of the opening and closing of the cover assembly 1.

[0073] It is understandable that since most photovoltaic devices are often required to be in a high temperature environment, in order to ensure the smooth opening and closing of the cover assembly 1, most of the structures in the cover assembly 1 are made of high temperature resistant materials to avoid deformation during use.

[0074] The utility model also provides a photovoltaic device, which includes the cover assembly 1 described in any of the above schemes. The photovoltaic device limits the opening and closing of the cover assembly 1 to a certain extent to avoid internal collision or jamming of the cover assembly 1, thereby improving the reliability and service life of the photovoltaic device.

[0075] It should be noted that the photovoltaic equipment can be an all-in-one equipment composed of one or more of texturing equipment, washing equipment, drying equipment, electroplating equipment, film removal equipment, and etching equipment, and is not specifically limited here.

[0076] Optionally, one or two cover plate assemblies 1 can be provided, both of which can realize the opening and closing of the opening of the processing tank 2.

[0077] Specifically, the photovoltaic device includes two cover plate assemblies 1, which are symmetrically arranged at the opening of the processing tank 2, thereby reducing the volume of a single cover plate assembly 1, making it easier for operators to open and close the cover plate assembly 1, and avoiding the situation where the cover plate assembly 1 is too large and inconvenient to operate, so that it can match photovoltaic devices of larger sizes and improve its adaptability.

[0078] Embodiment 2

[0079] This embodiment provides a cleaning device. The difference between this embodiment and the first embodiment lies in the different arrangement position of the driving member 51 .

[0080] Please refer to Figure 7 In this embodiment, the driving member 51 is horizontally installed on the second supporting member to prevent the opening and closing of the cover assembly 1 from being greatly affected by gravity, making it more convenient to unfold and fold the cover assembly 1.

[0081] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
