Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic technology.
Background Art
[0002] At present, there is no fixed inspection opening for regular inspection and maintenance of photovoltaic modules. During maintenance, operation and maintenance personnel locate on site, remove the photovoltaic panels, and then perform re-inspection. Since the photovoltaic brackets have been built and cross beams, inclined beams, etc. are arranged under the modules, if operation and maintenance personnel remove the modules during maintenance and then transfer them from above the cross beams to the ground, at least two staff members are required to operate together. For the sunrooms and in-hospital brackets with relatively high brackets, due to the high bracket height, it is relatively dangerous during the process of transferring the photovoltaic modules from the top, and a single operation and maintenance staff member cannot complete it. The operation and maintenance work is difficult and the operation is relatively difficult. For example, when transferring a module from one bracket to another, it is very difficult to place the modules neatly to avoid scratching the panel of another module by the frame of the moving module, resulting in cracks, etc., thus causing losses to the modules, affecting the power generation income, and making the later operation and maintenance labor cost high and the efficiency low.
Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic system convenient for maintenance.
[0004] To solve the above technical problem, the utility model adopts the following technical scheme:
[0005] A photovoltaic system convenient for maintenance, comprising a photovoltaic array composed of a plurality of photovoltaic modules. The photovoltaic array is provided with an inspection opening, and a switchable photovoltaic module is provided at a position corresponding to the inspection opening. A pulley fixing assembly is installed on the C side of the frame of the switchable photovoltaic module. The pulley fixing assembly includes a pulley. A pulley track is provided on the A side of the frame of the photovoltaic module adjacent to the switchable photovoltaic module. During maintenance, the switchable photovoltaic module cooperates with the pulley track through the pulley to open the inspection opening.
[0006] Preferably, the pulley fixing assembly includes a pulley fixing seat provided with a clamping groove and a fastener for fixing the clamping groove to the C side of the frame.
[0007] Preferably, the pulley fixing seat is provided with a pulley installation groove connected to the lower side of the clamping groove. The pulley is installed in the pulley installation groove, and a pulley shaft for rotatably supporting the pulley is provided between the two side walls of the pulley installation groove.
[0008] Preferably, the fastener is a fixing bolt passing through the upper and lower sides of the clamping groove; and / or, the upper side of the clamping groove is provided with an anti-slip convex surface.
[0009] Preferably, both ends of the pulley track are provided with limit blocks.
[0010] Preferably, the limit stop is made of hard plastic rubber.
[0011] Preferably, the back of the limit stop is adhesive and is adhesively fixed to the pulley track.
[0012] Preferably, the back of the pulley track is adhesive and is adhesively fixed to the frame.
[0013] Preferably, the pulley is provided with a wheel groove, and the middle of the pulley track is provided with a middle convex portion that cooperates with the wheel groove, and limit convex edges are provided on both sides.
[0014] Preferably, the pulley fixing seat is a sheet metal part; and / or, the pulley track is made of hard plastic rubber.
[0015] The technical solution adopted by the present utility model has the following beneficial effects:
[0016] 1. By providing a pulley on one of two adjacent photovoltaic modules and a pulley track on the other, during maintenance, the photovoltaic module can be opened, and the inspection opening can be opened through the cooperation of the pulley and the pulley track, enabling the inspection opening to have the ability to be fully opened during operation and maintenance. In this way, when maintenance, inspection, or cleaning is required, by pushing the openable photovoltaic module, the maintenance personnel can easily and quickly push the photovoltaic module with the pulley completely onto the photovoltaic module with the pulley track, realizing easy opening of the inspection opening and providing unobstructed maintenance and inspection; when the inspection is completed, the openable photovoltaic module is slid upward through the cooperation of the pulley and the pulley track and installed in its original position.
[0017] Since the openable photovoltaic module with the pulley is on the photovoltaic module with the pulley track, they do not directly contact, but achieve overhead movement and placement through the cooperation of the pulley and the pulley track, avoiding scratches on the surface of the photovoltaic module with the pulley track caused by the frame of the openable photovoltaic module.
[0018] Therefore, the above design not only improves work efficiency but also reduces potential risks during maintenance, providing a strong guarantee for the long-term stable operation of the photovoltaic system.
[0019] 2. After inserting the clamping groove into the C side of the frame and tightening the fastener, the pulley fixing seat can be quickly installed on the C side of the frame.
[0020] 3. Install the pulley in the pulley installation groove to prevent the pulley from moving laterally, thereby maintaining the relative cooperation position with the pulley track.
[0021] 4. The fastener is a fixing bolt passing through the upper and lower sides of the clamping groove and avoiding the C side of the frame, which facilitates quick installation and eliminates the need for an additional connection structure on the C side of the frame. Since the upper side of the clamping groove is provided with anti-slip convex surfaces, the friction can be increased to prevent relative sliding and loosening between the clamping groove and the C side of the frame.
[0022] 5. Limit blocks are provided at both ends of the pulley track. Since the back of the limit block is adhesive and is bonded and fixed to the pulley track, the limit block near the inspection opening is not installed temporarily to facilitate lifting the openable photovoltaic module, enabling the pulley to cooperate with the pulley track. After the inspection opening is opened, the limit block near the inspection opening is installed to limit the openable photovoltaic module during maintenance and keep the inspection opening in an open state.
[0023] 6. Both the limit block and the pulley track are made of hard plastic rubber, which not only has high strength but also is wear-resistant and can be used for a long time.
[0024] 7. Relying on the self-gravity of the openable photovoltaic module, the pulley forms a fit with the pulley track. Moreover, due to the limitation of the middle convex part and the limit convex edge, the pulley is prevented from separating from the pulley track.
[0025] 8. The pulley fixing seat is a sheet metal part, which has the advantages of light weight, high strength, low cost, and good mass production performance. Moreover, due to its certain elasticity, the clamping groove can elastically clamp on the C side of the frame and then be fastened with fixing bolts, ensuring reliable fixation.
[0026] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings.

[0043] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.
[0044] The terms used in the present utility model are for the purpose of describing specific embodiments only and are not intended to limit the present utility model. For example, the terms indicating orientation or positional relationship such as "upper", "lower", "inner", "outer", etc. are only based on the orientation or positional relationship shown in the drawings.

[0047] In the present utility model, unless otherwise clearly specified and defined, the terms such as "installation", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0048] Refer to Figures 1 to 13 As shown, this embodiment provides a photovoltaic system convenient for maintenance, including a photovoltaic array 100 composed of a plurality of photovoltaic modules. The periphery of the photovoltaic modules is provided with a frame 10, and the frame has an A side 101 on the upper side and a C side 102 on the lower side. The photovoltaic array is provided with a maintenance opening 1003, and a photovoltaic module that can be opened is provided corresponding to the position of the maintenance opening. A pulley fixing assembly 1 is installed on the C side 102 of the frame of the photovoltaic module that can be opened. The pulley fixing assembly 1 includes a pulley 11, and a pulley track 2 is provided on the A side 101 of the frame of the photovoltaic module adjacent to the photovoltaic module that can be opened. During maintenance, the photovoltaic module that can be opened cooperates with the pulley track 2 through the pulley 11 to open the maintenance opening 1003.
[0049] Here, the openable photovoltaic module is referred to as the first photovoltaic module 1001, and the photovoltaic module adjacent to the openable photovoltaic module is the second photovoltaic module 1002. And generally, the first photovoltaic module 1001 is arranged in the central area of the photovoltaic array, and the second photovoltaic module 1002 is arranged on the longitudinal lower side of the first photovoltaic module. In this way, when opening the maintenance port, the first photovoltaic module can slide down easily by means of the inclination.
[0050] In the above technical solution, by arranging a pulley on one of the two adjacent photovoltaic modules and a pulley track on the other, during maintenance, the openable photovoltaic module can cooperate with the pulley and the pulley track to open the maintenance port, enabling the maintenance port to have the ability to be fully opened during operation and maintenance. In this way, when maintenance, repair or cleaning is required, by pushing the openable photovoltaic module, the maintenance personnel can easily and quickly push the photovoltaic module with pulleys completely onto the photovoltaic module with a pulley track, realizing the easy opening of the maintenance port and providing unobstructed maintenance and repair; when the maintenance is completed, the openable photovoltaic module is slid upward through the cooperation of the pulley and the pulley track and installed in its original position.
[0051] Since the openable photovoltaic module with pulleys is on the photovoltaic module with a pulley track, they do not directly contact, but realize overhead movement and placement through the cooperation of the pulley and the pulley track, avoiding scratches on the surface of the photovoltaic module with a pulley track caused by the frame of the openable photovoltaic module.
[0052] Therefore, the above design not only improves work efficiency but also reduces potential risks during maintenance, providing a strong guarantee for the long-term stable operation of the photovoltaic system.
[0053] Specifically, the pulley fixing assembly 1 includes a pulley fixing seat 13 provided with a clamping groove 131 and a fastener for fixing the clamping groove to the C side of the frame. After inserting the clamping groove into the C side of the frame, the fastener is tightened, so that the pulley fixing seat can be quickly installed on the C side of the frame. The pulley fixing seat 13 is provided with a pulley installation groove 132 connected to the lower side of the clamping groove. The pulley 11 is installed in the pulley installation groove 132. A pulley shaft for rotatably supporting the pulley is provided between the two side walls of the pulley installation groove. The pulley installation groove limits the pulley to prevent lateral movement of the pulley, so as to maintain the relative cooperation position with the pulley track. The position of the pulley corresponds to the position of the upper A side, so as to facilitate cooperation with the pulley track of the photovoltaic module with a pulley track. The fastener is a fixing bolt 12 passing through the upper and lower sides of the clamping groove 131, and the fixing bolt 12 avoids the C side of the frame, which is convenient for quick installation without the need to design an additional connection structure on the C side of the frame. The upper side of the clamping groove 131 is provided with an anti-slip convex surface 133 to increase the friction force and prevent relative sliding and loosening between the clamping groove and the C side of the frame.
[0054] Further, limit stops 23 are provided at both length ends of the pulley track 2. The back of the limit stop 23 is adhesive and is adhered and fixed to the pulley track 2. Among them, the limit stop near the inspection opening is not installed temporarily to facilitate lifting the openable photovoltaic module, so that the pulley cooperates with the pulley track. After the inspection opening is opened, the limit stop near the inspection opening is installed to limit the openable photovoltaic module during maintenance and keep the inspection opening in an open state.
[0055] To facilitate the installation of the pulley track, the back of the pulley track 2 is adhesive and is adhered and fixed to the frame. Since this design relies on the original photovoltaic support, the main increase in cost is the adhesive pulley track on the back and the pulley fixing seat, and no special modification is required for the original photovoltaic support, reducing the cost.
[0056] Specifically, the pulley 11 is provided with a wheel groove, and the middle of the pulley track 2 is provided with a middle convex portion 21 that cooperates with the wheel groove, and limit convex edges 22 are provided on both sides. Relying on the self-gravity of the openable photovoltaic module, the pulley forms a cooperation with the pulley track, and due to the limitation of the middle convex portion and the limit convex edges, the pulley is prevented from separating from the pulley track.
[0057] Preferably, the pulley fixing seat 13 is a sheet metal part. Sheet metal parts have the advantages of light weight, high strength, low cost, and good mass production performance. Moreover, due to having a certain elasticity, the clamping groove can elastically clamp on the C side of the frame, and then a fixing bolt is used for reliable fixation. The pulley track 2 is made of hard plastic rubber. The limit stop 23 is made of hard plastic rubber. Hard plastic rubber not only has high strength but also is wear-resistant and can be used for a long time.
[0058] Referring to the prior art, the photovoltaic array 100 is installed on the photovoltaic support 200, and the photovoltaic support 200 includes longitudinal beams, cross beams 201, columns, etc. The photovoltaic module is fixed to the cross beam 201 by a pressing plate assembly 3. The pressing plate assembly 3 includes an upper pressing plate 31 pressed on the C side of the frame, a lower pressing plate 32 provided on the lower side of the cross beam, and a pressing plate bolt 33 connecting the upper pressing plate and the lower pressing plate. Among them, the pressing plate bolt is a U-shaped bolt, and the mouth is downward, and the nut is tightened below the cross beam.
[0059] The installation and use method of the present utility model is described as follows:
[0060] When initially installing the photovoltaic module, according to the design requirements, the adhesive pulley track on the back is pasted onto the second photovoltaic module frame adjacent to the inspection opening. The limit stops are first fixed at the lowermost ends of the A sides of the horizontal two-side frames of the first photovoltaic module frame with the pulley track. The connection scheme between it and the cross beam still uses the pressing plate assembly for fixation.
[0061] The first photovoltaic module is pre-installed with a pulley fixing assembly. Among them, the clamping groove of the pulley fixing seat clamps the C side of the module frame, and then it is fixed by a fixing bolt. The connection scheme between it and the cross beam still uses the pressing plate assembly for fixation.
[0062] Other photovoltaic modules are installed normally.
[0063] Under normal use conditions, the photovoltaic modules are fixed by the pressing plate assembly, and the pulley track and pulley fixing assembly do not affect the use of the photovoltaic support and the normal power generation of the photovoltaic modules.
[0064] In the operation and maintenance state, first loosen the pressing plate bolts at the connection position between the first photovoltaic module and the crossbeam, then lift the photovoltaic module upward and place it on the adjacent second photovoltaic module with a pulley track. Then, slide the first photovoltaic module over through the pulley. Open the inspection opening. When the first photovoltaic module slides to the edge of the second photovoltaic module below and the front pulley reaches the position of the limit stop, stop. Then install a limit stop behind the rear pulley to keep the first photovoltaic module above stationary, thus opening the inspection opening.
[0065] As described above, it is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
