Description

Technical Field

[0002] Traditional fixed photovoltaic modules are limited by their installation location, large footprint, and limited flexibility, making them difficult to meet energy needs in certain scenarios.

With their flexible deployment, rapid response, and efficient use of solar energy, they have become a key development direction in photovoltaic technology.

[0003] The light-receiving surface of a photovoltaic module refers to the surface of the module that receives sunlight and converts it into electricity. The size of the light-receiving surface directly affects the module's energy conversion efficiency. However, a larger light-receiving surface results in a larger supporting structure for the module, which in turn increases the overall size of the photovoltaic storage device, making it difficult to transport and transfer.

[0076] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0077] like Figures 1-17 As shown, the photovoltaic storage device in the embodiment of the present application includes a support structure 7 and a photovoltaic module, wherein:

[0078] The supporting structure 7 is the main structure for supporting the photovoltaic components.

[0079] like Figure 13-16As shown, the support structure 7 in this embodiment has a cavity (in a specific implementation, the support structure 7 can be a support box, a support cabinet, etc., or the support structure 7 can also be a frame structure formed by connecting multiple cross beams and multiple longitudinal beams, and the outer periphery of the frame structure is provided with a metal plate for enclosing the cavity), and the inverter 15 and the energy storage battery 17 are provided in the cavity. Among them:

[0080] The inverter 15 is electrically connected to the photovoltaic module, and the energy storage battery 17 is electrically connected to the inverter 15 .

[0081] Under the above structure, the photovoltaic module converts light energy into electrical energy, and then transmits the electrical energy directly to the load end through the inverter 15. When the power consumption of the load end is less than the power generation of the photovoltaic module, the excess power generated by the photovoltaic module will be stored in the energy storage battery 17 through the inverter 15. At night, the power of the energy storage battery 17 can be used by the load at night through the inverter 15.

[0082] Further preferably, the photovoltaic storage device includes a diesel generator 16, and the diesel generator 16 is electrically connected to the inverter cavity. When encountering rainy weather and the photovoltaic storage device cannot generate electricity, the diesel generator 16 can be started through the inverter 15. At this time, the diesel generator 16 is the main power generation device for load use.

[0083] In addition, the energy storage battery 17 has a charging port and a discharging port, wherein the charging port is used to charge the energy storage battery 17 using AC power. In this way, when the photovoltaic storage device cannot be used to generate electricity in the external environment and the power generation of the diesel generator 16 cannot meet the requirements, the system can be pulled to a place with AC power and the energy storage battery 17 can be charged with AC power. When the energy storage battery 17 is fully charged, it can be moved to a place without power supply to provide electricity.

[0084] In this embodiment, since the inverter 15 and the energy storage battery 17 (and the diesel generator 16) are integrated into the interior of the support structure 7, the overall compactness of the photovoltaic storage device can be improved, thereby reducing the overall volume of the photovoltaic storage device.

[0085] Photovoltaic modules are components used in solar storage devices to convert solar energy into electrical energy.

[0086] like Figure 13-16 As shown, in this embodiment, the photovoltaic assembly is arranged on the top of the support structure 7, and includes an expansion and retraction bracket and a plurality of photovoltaic panels 202 arranged on the expansion and retraction bracket, and the expansion and retraction bracket can drive at least part of the photovoltaic panels 202 to move in different directions to increase the light-receiving area of ​​the photovoltaic assembly (the light-receiving area of ​​the photovoltaic assembly refers to the area of ​​the unblocked part of the photovoltaic assembly that can receive solar radiation, that is, the sum of the areas of the unblocked parts of the light-receiving surfaces of all photovoltaic panel units 2).

[0087] The aforementioned expansion and retraction bracket refers to a bracket-like structure that can be used to change the relative positions of the plurality of photovoltaic panels 202 to increase or decrease the light-receiving area of ​​the photovoltaic assembly.

[0088] In a specific implementation, the deployment bracket can change the relative positions of the plurality of photovoltaic panels 202 by causing some photovoltaic panels 202 to slide relative to other photovoltaic panels 202, or by causing some photovoltaic panels 202 to flip relative to other photovoltaic panels 202. Of course, the present application is not limited thereto. For example, the deployment bracket can change the relative positions of the plurality of photovoltaic panels 202 by causing the photovoltaic panels 202 to rotate about a certain axis.

[0089] Furthermore, in a specific implementation, the deployment bracket can be made of a metal material with strong weather resistance (i.e., the ability to withstand various climatic conditions and their effects in the natural environment), such as aluminum alloy and / or galvanized steel. Of course, the present application is not limited thereto, and in a specific implementation, the deployment bracket can also be made of ordinary carbon steel with a rust-proof surface treatment, or composite materials such as carbon fiber reinforced plastic.

[0090] When using the photovoltaic storage device of this embodiment for photoelectric conversion, the photovoltaic storage device is first moved to a preset position. Then, the photovoltaic panels 202 are moved in different directions using the deployment and retraction brackets, thereby reducing the overlap between different photovoltaic panels 202, thereby increasing the light-receiving area of ​​the photovoltaic module and ensuring the photovoltaic conversion efficiency of the photovoltaic module. When the photovoltaic storage device needs to be moved, the deployment and retraction brackets are first used to move the photovoltaic panels 202 toward the center position, thereby increasing the overlap between different photovoltaic panels 202, and then the photovoltaic storage device is moved.

[0091] As described above, in this embodiment, when the photovoltaic assembly is converted between the deployed and collapsed states using the deployment and retraction brackets, the photovoltaic panels 202 move in different directions. When the photovoltaic storage device is collapsed, more photovoltaic panels 202 can be overlapped, making the photovoltaic assembly more compact and smaller in size. As can be seen, the smaller size of the photovoltaic assembly allows the support structure 7 used to support the photovoltaic assembly to be correspondingly smaller, further reducing the overall size of the photovoltaic storage device. With this arrangement, the volume requirement for the traction device 9 can be greatly reduced when the photovoltaic storage device is transferred, making it easier to tow and transfer the photovoltaic storage device.

[0092] In some embodiments, the photovoltaic assembly is rotatably connected to the support structure 7 via a hinge shaft; the photovoltaic storage device also includes an angle adjustment assembly, which is used to drive the photovoltaic assembly to rotate around the hinge shaft to adjust the angle between the light and the light-receiving surface of the photovoltaic assembly.

[0093] During the use of photovoltaic modules, the absorption of solar radiation energy can be optimized by adjusting the tilt angle of the photovoltaic modules, thereby improving the power generation efficiency of the photovoltaic storage equipment.

[0094] In an exemplary embodiment, the angle adjustment assembly includes a lifting structure 11 and a locking assembly 12 .

[0095] Specifically, the lifting structure 11 is arranged inside the cavity of the support structure 7, and the output end of the lifting structure 11 extends to the outside of the support structure 7. In this way, the space utilization rate of the inner cavity of the support structure 7 can be improved, thereby further improving the overall structural compactness of the optical storage device and reducing the volume of the optical storage device.

[0096] Furthermore, the output end of the lifting structure 11 is hinged to the photovoltaic module.

[0097] In an alternative embodiment, if Figure 16 As shown, the lifting structure 11 can be a hydraulic rod, one end of which is hinged on the bottom plate 701 of the support structure 7, and the other end is hinged to the photovoltaic bracket 1 of the photovoltaic module. In this way, the angle of the photovoltaic module can be adjusted by the extension and contraction of the hydraulic rod.

[0098] In an optional embodiment, the lifting structure 11 may also be a lifting assembly formed by a screw and a threaded sleeve.

[0099] In addition, regarding the number of lifting structures 11, in specific implementation, adaptive design can be made according to needs, and this application does not make specific restrictions on this. However, it should be noted that when multiple lifting structures 11 are provided, the multiple lifting structures 11 should be able to start and stop synchronously.

[0100] The locking assembly 12 is disposed between the photovoltaic module and the support structure 7 and is used to prevent the photovoltaic module from rotating about the hinge axis. This prevents the photovoltaic module from automatically adjusting its tilt angle, thereby helping the photovoltaic module maintain an optimal tilt angle and improving its photoelectric conversion efficiency.

[0101] In an exemplary embodiment, the locking assembly 12 includes a slider 1201, a connecting rod 1202, and a locking member, wherein:

[0102] The slider 1201 is slidably arranged on the support structure 7; specifically, Figure 17 As shown, the slider 1201 is slidably disposed on the outer side wall 702 of the vehicle support frame 602 .

[0103] One end of the connecting rod 1202 is hinged to the photovoltaic component, and the other end is hinged to the slider 1201; in this way, the connecting rod 1202 can be used to realize the linkage between the photovoltaic component and the slider 1201, that is, when the inclination angle of the photovoltaic component changes, the position of the slider 1201 on the outer wall 702 needs to change synchronously, so that the locking component 12 in this embodiment can fix the inclination angle of the photovoltaic component by fixing the position of the slider 1201 relative to the outer wall 702.

[0104] The locking member is provided on the slider 1201 and / or the supporting structure 7 and is used to fix the position of the slider 1201 relative to the supporting structure 7 .

[0105] For example, in a specific implementation, the locking member can be a locking screw that is threadedly connected to the slider 1201 and can abut against the outer wall 702. Of course, the present application is not limited to this. For example, the locking member can also be a clamping member that can achieve clamping and fixing of the slider 1201 and the outer wall 702.

[0106] Furthermore, in a specific implementation, the slider 1201 is connected to the support structure 7 via a guide mechanism comprising a guide groove and a protrusion. The guide groove is provided on one of the support structure 7 and the slider 1201 and extends along the height of the support structure 7. The protrusion is provided on the other of the support structure 7 and the slider 1201 and is slidably connected to the guide groove. In this manner, the guide groove and the protrusion restrict the movement of the slider 1201 on the outer wall 702.

[0107] In some embodiments, a roller assembly is provided at the bottom of the support structure 7 for driving the support structure 7 to move.

[0108] In specific implementation, the roller assembly can be arranged on the side wall of the support structure 7, or can also be arranged on the bottom frame beam of the support structure 7 for supporting the bottom plate 701. This application does not make specific limitations on this.

[0109] The roller assembly is a structure used to facilitate the movement of the support structure 7. Figure 14-16 As shown, the roller assembly includes multiple rollers 703, all of which are rotatably arranged at the bottom of the support structure 7, and the treads of the rollers 703 (i.e., the surfaces of the rollers 703 that surround the rotating axis of the rollers 703 and are parallel to the axial direction of the rotating axis of the rollers 703) can all abut against the support surface of the optical storage device.

[0110] like Figure 14 and Figure 16 As shown, a support assembly is provided on the outer peripheral side of the support structure 7, and the support assembly is used to support the support structure 7 and enable the roller 703 to be suspended in the air.

[0111] When the optical storage device is moved to a designated position, the roller 703 is suspended by adjusting the support assembly, and then the support assembly is used to replace the roller 703 to support the support structure 7. In this way, the support stability can be effectively improved.

[0112] In some embodiments, the support structure 7 includes a plurality of support beams extending outwardly parallel to the base plate 701 of the support structure 7 (i.e., extending away from the support structure 7), and support columns 8 arranged one-to-one with the support beams. The arrangement of the support beams can effectively avoid the problem of insufficient support stability caused by the reduction in the volume of the support structure 7.

[0113] In a preferred embodiment, the support beam is a telescopic beam, and / or the support beam is rotatably connected to the support structure 7. In this way, when the optical storage device is in a folded state, the end of the support beam extending outward can be retracted, and / or the support beam can be rotated to reduce the impact of the setting of the support beam on the volume of the optical storage device in the folded state.

[0114] More specifically, the support column 8 is provided at one end of the support beam away from the support structure 7, and the support column 8 includes a fixed portion and a telescopic portion. The fixed portion is fixedly connected to the support beam and extends along the supporting direction, and the telescopic portion is movably provided on the fixed portion along the supporting direction.

[0115] When the support assembly is needed to support the optical storage device, it is only necessary to control the telescopic portion to move in a direction away from the chassis frame until the roller 703 is suspended in the air.

[0116] It should be understood that the above-mentioned support column 8 including a fixed part and a telescopic part is only an exemplary implementation method of the support column 8, but the embodiment of the present application is not limited to this. For example, the support column 8 can also be a rigid support structure 7 that cannot be telescoped, and the support column 8 is rotatably set on the chassis frame.

[0117] like Figure 13-16 As shown, the photovoltaic storage device also includes a carrying trolley 6, which is a carrying structure for facilitating long-distance transportation of photovoltaic components; and the supporting structure 7 is a frame structure for facilitating short-distance adjustment of photovoltaic components.

[0118] In this embodiment, when the solar storage device needs to be transported over long distances, the support structure 7 and the carrying trolley 6 are assembled. When the solar storage device needs to be adjusted over a short distance, the support structure 7 and the carrying trolley 6 can be separated. This avoids inconveniences caused by the large turning radius of the carrying trolley 6, thereby making the position adjustment of the solar storage device more flexible.

[0119] In some embodiments, the carrying trolley 6 includes wheels 601, a frame 602 and a towing rack 603, wherein:

[0120] The wheels 601 are used to facilitate the movement of the carrying trolley 6 .

[0121] The vehicle frame 602 is a support structure 7 for forming a bearing surface, and a running connection structure for connecting the wheels 601 is provided on the vehicle frame 602 to facilitate connecting the wheels 601 and the vehicle frame 602 .

[0122] The towing frame 603 has a traction end and a fixed end. The fixed end is fixedly connected to the vehicle frame 602, and the traction end is provided with a traction structure for connecting to a traction device 9 (such as a vehicle). The towing frame 603 is used to facilitate the connection between the carrying vehicle 6 and the traction device 9, thereby making it easier to move the optical storage device.

[0123] Furthermore, the trolley 6 includes an inclined step 605, one end of which is hinged to the side of the frame 602 away from the towing bracket 603, and the other end of which can be attached to a surface supporting the solar storage device. Thus, after the solar storage device reaches a predetermined position, the inclined step 605 can be used to load and unload the vehicle frame 602 and other structures, thereby facilitating the loading and unloading of the supporting structure 7 and other structures.

[0124] like Figure 14 and Figure 15 As shown, in a specific implementation, the above-mentioned inclined pedal 605 can be a metal plate with relatively high strength, such as an aluminum alloy plate or a high-strength steel plate.

[0125] In addition, the number of inclined pedals 605 can be one or two, and this application does not make any specific restrictions on this. During implementation, adaptive design can be performed as needed.

[0126] It should be understood that the above-mentioned hinged connection of the inclined pedal 605 to the frame 602 is only an exemplary connection method between the frame 602 and the inclined pedal 605, and the present application is not limited thereto. For example, the inclined pedal 605 can also be detachably connected to the frame 602 through a quick-release structure.

[0127] Furthermore, on the basis of the above-mentioned inclined pedal 605, the carrying trolley 6 also includes a winch 606, which is fixedly arranged on one side of the frame 602 close to the towing frame 603 and can at least be used to tow the support structure 7 to move.

[0128] For example, Figure 14-16 As shown, the winch 606 includes a fixed frame, a fixed pulley rotatably disposed on the fixed frame, a cable wound around the fixed pulley, and a driving structure for driving the fixed pulley to rotate.

[0129] Under the above arrangement, during operation, after the free end of the cable is fixed to the support structure 7 , the driving structure is started to retract and release the cable, and the support structure 7 can be loaded and unloaded using the winch 606 .

[0130] Furthermore, for the convenience of description, the first side is used below to represent the side of the frame 602 connected to the inclined pedal 605 , and the second side is used to represent the side of the frame 602 connected to the trailer rack 603 .

[0131] like Figure 14 As shown, a limiting track 10 is provided on the bearing surface of the frame 602, the limiting track 10 is provided opposite to the limiting track 10, and extends from the first side to the second side; the support structure 7 is movably connected to the limiting track 10, and the support structure 7 can move along the extension direction of the limiting track 10.

[0132] By setting the limiting rail 10 to limit the moving direction of the support structure 7 on the load-bearing surface of the frame 602, it is possible to effectively prevent the support structure 7 from being deviated in its moving direction during loading and unloading, thereby causing the support structure 7 to fall from the load-bearing trolley 6.

[0133] Furthermore, the limiting track 10 is a limiting groove formed in the support structure 7, and the tread of the roller 703 abuts against the bottom of the limiting groove. Under this arrangement, the limiting track 10 can enhance the restraining effect on the support structure 7, further reducing the probability of the support structure 7 running off on the carrying trolley 6.

[0134] For example, the limiting grooves may be formed by parallel and spaced-apart protrusions provided on the frame 602 , or may be formed by depressions on the bearing surface of the frame 602 .

[0135] Furthermore, based on the above-mentioned carrying trolley 6, as Figure 14-16 As shown, the wheel 601 includes a supporting walking wheel 6011 and a supporting guide wheel 6012, wherein:

[0136] The supporting walking wheel 6011 is connected to the walking connection structure through a shock-absorbing assembly and is arranged close to the first side of the frame 602, that is, close to the side of the frame 602 away from the towing frame 603.

[0137] In specific implementation, the shock absorbing assembly can be adaptively designed as needed. For example, the above-mentioned shock absorbing assembly can be a shock absorbing structure formed by multiple leaf springs, or a shock absorbing structure formed by multiple hydraulic shock absorbers, or the shock absorbing assembly can also be a shock absorbing system formed by air springs.

[0138] The support guide wheel 6012 is set on the second side of the frame 602 or the trailer frame 603 through the support rod 604; and the support guide wheel 6012 is rotatably set on the bottom end of the support rod 604, and the support rod 604 can be rotatably set around its own axis on the second side of the frame 602 or the trailer frame 603.

[0139] More specifically, Figure 14-16As shown, the extension direction of the support rod 604 is perpendicular to the bearing surface of the carrying trolley 6, and the support guide wheel 6012 is rotatably arranged at the bottom end of the support rod 604 (that is, the end of the support rod 604 close to the ground) through the axis structure, and the tread of the support guide wheel 6012 can abut against the supporting surface of the optical storage device.

[0140] In the process of moving the optical storage device using the vehicle-mounted frame 602, the moving direction of the optical storage device can be changed by rotating the support rod 604, that is, the optical storage device in the embodiment of the present application can self-adjust the moving direction. Compared with the method of completely relying on the traction device 9 to adjust the moving direction, the support guide wheel 6012 provided in the embodiment of the present application can effectively reduce the turning radius of the optical storage device, thereby making it easier to move the optical storage device and control the moving path of the optical storage device.

[0141] In addition, as mentioned above, the supporting walking wheels 6011 and the supporting guide wheels 6012 in the embodiment of the present application are arranged on opposite sides of the carrying trolley 6. This arrangement is conducive to distributing the load, thereby improving the stability of the support.

[0142] It should be understood that the above is only an exemplary implementation of the support guide wheel 6012, but the present application is not limited thereto. For example, in a specific implementation, the support rod 604 can also be fixed to the frame 602 or the trailer 603, and the support guide wheel 6012 can be configured as a universal wheel. This can also achieve the purpose of enabling the optical storage device to self-adjust its movement direction.

[0143] Further preferably, based on the above-mentioned wheel 601 including the supporting running wheel 6011 and the supporting guide wheel 6012, the number of the supporting running wheels 6011 can be two, which is more conducive to reducing the steering resistance of the solar storage device.

[0144] In some embodiments, the solar energy storage device further includes an anemometer 13 and an alarm light 14, wherein:

[0145] The anemometer 13 is arranged on the outer wall 702 of the support structure 7 and is used to detect the wind speed of the surrounding environment of the solar storage device; the alarm light 14 is arranged on the outer wall 702 of the support structure 7 and is electrically connected to the anemometer 13 to alarm when the wind speed reaches a preset level.

[0146] When the solar-powered storage device is in use, the anemometer 13 can monitor the wind speed level in the environment where the solar-powered storage device is located in real time. When the wind speed reaches a preset level, the alarm light 14 is activated to remind the staff to take appropriate measures (such as strengthening the support of the photovoltaic modules or deactivating the solar-powered storage device), thereby preventing the solar-powered storage device from being damaged by strong winds.

[0147] In some embodiments, the deployment bracket includes a photovoltaic bracket 1 and multiple photovoltaic panel brackets 201, wherein the photovoltaic bracket 1 is connected to the support structure 7; all photovoltaic panel brackets 201 are provided with multiple photovoltaic panels 202 that can be deployed along a first direction; and at least one photovoltaic panel bracket 201 is movably connected to the photovoltaic bracket 1 to be able to drive the photovoltaic panel 202 to move along a second direction; wherein the first direction and the second direction meet the vertical condition (that is, the sliding direction of the mobile photovoltaic panel is approximately perpendicular to the extension direction of the first guide rail 102. For example, the angle between the sliding direction of the mobile photovoltaic panel and the extension direction of the first guide rail 102 can be in the range of 85° to 95°).

[0148] Under the structure of the above-mentioned expansion and retraction bracket, when the photovoltaic storage device needs to be transferred from the folded state to the unfolded state, the photovoltaic panel bracket 201 is first controlled to move relative to the photovoltaic bracket 1, so that the photovoltaic storage device is transferred from the folded state to the intermediate state, and then the photovoltaic panel 202 on the photovoltaic panel bracket 201 is controlled to be expanded along the first direction, thereby transferring the photovoltaic storage device from the intermediate state to the expanded state.

[0149] The active connection between the photovoltaic panel support 201 and the photovoltaic support 1 may be a sliding connection or a hinge connection, which is not specifically limited in this application.

[0150] Furthermore, for ease of understanding, the specific setting method of the deployment bracket is exemplified below using the sliding connection between the photovoltaic panel bracket 201 and the photovoltaic bracket 1 as an example, and for ease of description, in this embodiment, a photovoltaic panel bracket 201 and a plurality of photovoltaic panels 202 arranged on the photovoltaic panel bracket 201 are recorded as a photovoltaic panel unit 2.

[0151] like Figures 1-12 As shown, the photovoltaic assembly includes a photovoltaic bracket 1 and a plurality of photovoltaic panel units 2. Among them:

[0152] The photovoltaic support 1 is a structural system used to install, fix and adjust the position of the photovoltaic panel unit 2.

[0153] like Figure 5-Figure 7 As shown, the photovoltaic bracket 1 in this embodiment includes a bracket body 101 , a first guide rail 102 and a second guide rail 103 .

[0154] The bracket body 101 is the core load-bearing structure of the photovoltaic bracket 1 and is used to provide basic support for the entire photovoltaic assembly.

[0155] Optionally, the support body 101 may be a frame structure formed by a plurality of cross beams, longitudinal beams, etc. The cross beams and longitudinal beams are preferably made of a metal material with strong weather resistance and high strength.

[0156] Optionally, the bracket body 101 may also be provided with an open box-like structure.

[0157] The first guide rail 102 and the second guide rail 103 are both structures in the photovoltaic bracket 1 for adjusting the position of the photovoltaic panel unit 2. Adjusting the position of the photovoltaic panel unit 2 here refers to adjusting the position of the photovoltaic panel unit 2 relative to the bracket body 101.

[0158] Specifically, continue as Figure 5-Figure 7 As shown, in this embodiment, the first guide rail 102 is fixedly connected to the bracket body 101 , and the second guide rail 103 is movably connected to the bracket body 101 .

[0159] This application does not specifically limit the manner in which the first guide rail 102 is fixedly connected to the bracket body 101. For example, the first guide rail 102 and the bracket body 101 may be connected by a connection structure such as bolts; or the first guide rail 102 may be welded to the bracket body 101.

[0160] Furthermore, the aforementioned movable connection between the second guide rail 103 and the bracket body 101 refers to a connection to the bracket body 101 that enables the second guide rail 103 to move relative to the bracket body 101. This includes, but is not limited to, hinged connections and sliding connections. Furthermore, a detachable connection between the second guide rail 103 and the bracket body 101 also falls within the scope of the movable connection between the second guide rail 103 and the bracket body 101 in this application.

[0161] Furthermore, based on the above-mentioned active connection between the second guide rail 103 and the bracket body 101, the second guide rail 103 has a first state and a second state, and as the second guide rail 103 moves relative to the bracket body 101, the second guide rail 103 can switch between the above-mentioned first state and the second state.

[0162] In the first state, the second guide rail 103 is located on one side of the first guide rail 102 in the width direction, or the extension direction of the second guide rail 103 forms a non-zero angle with the extension direction of the first guide rail 102. That is, in the first state, the guide rail system composed of the first guide rail 102 and the second guide rail 103 requires less space in the extension direction of the first guide rail 102.

[0163] In the second state, the second guide rail 103 is located on one side of the length direction of the first guide rail 102, and the extension direction of the second rail is consistent with the extension direction of the first rail, and the support surface of the second rail is flush with the support surface of the first rail; that is, in the second state, the second guide rail 103 is essentially a structure for extending the first guide rail 102.

[0164] The photovoltaic panel unit 2 is the core component for converting light energy into electrical energy.

[0165] In this embodiment, a plurality of photovoltaic panel units 2 are provided, and at least one photovoltaic panel unit 2 is movably connected to the first guide rail 102; that is, in the embodiment of the present application, all photovoltaic panel units 2 can be movably connected to the first guide rail 102, or some photovoltaic panel units 2 can be movably connected to the first guide rail 102, and the remaining photovoltaic panel units 2 can be fixedly provided on the bracket body 101.

[0166] Furthermore, the photovoltaic panel unit 2 movably connected to the first guide rail 102 can be moved along the extension direction of the first guide rail 102 to the second guide rail 103 in the second state.

[0167] As described above, in the second state, the second guide rail 103 is actually an extension of the first guide rail 102, that is, the photovoltaic assembly in the embodiment of the present application forms a foldable track structure by setting the first guide rail 102 and the second guide rail 103. When the photovoltaic assembly needs to be transported, the second guide rail 103 is controlled to be in the first state, so that the structure of the photovoltaic assembly is more compact, so that the photovoltaic assembly can have a smaller volume; when the photovoltaic assembly needs to be used for photoelectric conversion, the second guide rail 103 is controlled to be in the second state. In this way, under the action of the second guide rail 103, the movable amount of the photovoltaic panel unit 2 along the first guide rail 102 is increased, thereby increasing the effective power generation area of ​​the photovoltaic assembly, so that the photovoltaic assembly has a higher energy conversion efficiency.

[0168] It should be noted that the number of photovoltaic panel units 2 can be adaptively designed according to needs in specific implementation, and this application does not make any specific restrictions on this.

[0169] For example, Figure 1-Figure 3 As shown, the photovoltaic panel unit 2 can be set to three, in the direction perpendicular to the light receiving surface of the photovoltaic panel unit 2 (i.e. Figure 1 The three photovoltaic panel units 2 are arranged in sequence. Two of the three photovoltaic panel units 2 are movably connected to the first guide rail 102, and the other is fixedly connected to the bracket body 101. Furthermore, the two photovoltaic panel units 2 movably connected to the first guide rail 102 both move along the extension direction of the first guide rail 102, and move in opposite directions.

[0170] In some embodiments, the photovoltaic panel unit 2 includes a photovoltaic panel support 201 and a plurality of photovoltaic panels 202.

[0171] The photovoltaic panel support 201 is a structural system in the photovoltaic panel unit 2 for installing, fixing and adjusting the position of the photovoltaic panel 202 .

[0172] Multiple photovoltaic panels 202 are all set on the photovoltaic panel bracket 201, and at least one photovoltaic panel 202 is a mobile photovoltaic panel, which is movably connected to the photovoltaic panel bracket 201, and the light-receiving area of ​​the photovoltaic panel unit 2 can change with the movement of the mobile photovoltaic panel unit relative to the photovoltaic panel bracket 201.

[0173] The light-receiving area of ​​the photovoltaic panel unit 2 refers to the area of ​​the unblocked portion of the photovoltaic panel unit 2 that can receive solar radiation, that is, the total area of ​​the unblocked portion of the light-receiving surfaces of all photovoltaic panels 202 .

[0174] Based on the photovoltaic panel unit 2 including the movable photovoltaic panel, the photovoltaic panel unit 2 has an overlapping state and an unfolded state, and as the movable photovoltaic panel moves relative to the photovoltaic panel support 201, the photovoltaic panel unit 2 can switch between the overlapping state and the unfolded state, thereby adjusting the light receiving area of ​​the photovoltaic panel unit 2.

[0175] The overlapping state means that the overlap between different photovoltaic panels 202 in the direction perpendicular to the light-receiving surface is no less than 80%. In other words, at least 80% of the projection of one photovoltaic panel 202 falls on the adjacent photovoltaic panel 202 in the direction perpendicular to the light-receiving surface. In this case, because the light-receiving surface of each photovoltaic panel 202 is largely blocked, the light-receiving area of ​​the photovoltaic panel unit 2 is small.

[0176] The expanded state means that the overlap between different photovoltaic panels 202 in the direction perpendicular to the light-receiving surface is less than 20%. In other words, in the direction perpendicular to the light-receiving surface, the projection of a photovoltaic panel unit 2 falls on the adjacent photovoltaic panel 202 by at most 20%. In this state, because only a small portion of the light-receiving surface of the photovoltaic panel 202 is blocked, the light-receiving area of ​​the photovoltaic panel unit 2 is larger.

[0177] It is understood that the aforementioned overlap between different photovoltaic panels 202 in the overlapping state and the overlap between different photovoltaic panels 202 in the deployed state are not limitations of this application; that is, in a specific implementation, the overlap between different photovoltaic panels 202 in the overlapping state and the overlap between different photovoltaic panels 202 in the deployed state can be adaptively adjusted as needed. However, it should be noted that when the photovoltaic panel unit 2 is movably connected to the first guide rail 102, in the overlapping state, the photovoltaic panels 202 and other structural members of the photovoltaic panel unit 2 should not interfere with the movement of the photovoltaic panel unit 2 on the first guide rail 102.

[0178] As mentioned above, the mobile photovoltaic panel is movably connected to the photovoltaic panel support 201, and the movably connected connection includes but is not limited to a hinged or sliding connection.

[0179] In an exemplary embodiment, the movable photovoltaic panel is hinged to the photovoltaic panel support 201 .

[0180] Specifically, the mobile photovoltaic panel can be hinged to the photovoltaic panel bracket 201 through the shaft hole structure, and the photovoltaic panel unit 2 can be switched between the overlapping state and the unfolded state by flipping the mobile photovoltaic panel.

[0181] In addition, in order to improve stability, when the mobile photovoltaic panel is hinged on the photovoltaic panel bracket 201, an auxiliary support structure 7 can be provided, and the auxiliary support structure 7 can support the mobile photovoltaic panel in the unfolded state.

[0182] The auxiliary support structure 7 may be a support structure 7 movably connected to the photovoltaic panel support 201 or a support structure 7 detachably connected to the photovoltaic panel support 201, and this application does not impose any specific restrictions on this. However, it should be ensured that when the photovoltaic panel units 2 are in an overlapping state, the auxiliary support structure 7 does not affect the movement of the photovoltaic panel units 2 on the first guide rail 102.

[0183] In an exemplary embodiment, the mobile photovoltaic panel is slidably connected to the photovoltaic panel support 201 .

[0184] Exemplarily, the movable photovoltaic panel may be slidably connected to the photovoltaic panel support 201 via a slide rail.

[0185] Specifically, the sliding rail includes an inner rail and an outer rail; wherein, the outer rail is a strip structure with a groove, and the extension direction of the groove is consistent with the length direction of the outer rail. The side of the outer rail away from the groove is connected to the photovoltaic panel bracket 201, and the inner rail can be slidably connected in the groove of the outer rail and connected to the mobile photovoltaic panel.

[0186] Further preferably, a structure such as a ball bearing may be provided between the inner rail and the outer rail for reducing friction.

[0187] In addition, based on the sliding connection of the mobile photovoltaic panel to the photovoltaic panel support 201, in a preferred embodiment, as shown in FIG. Figure 12 As shown, the sliding direction of the mobile photovoltaic panel and the extension direction of the first guide rail 102 meet the perpendicular condition. That is, the sliding direction of the mobile photovoltaic panel and the extension direction of the first guide rail 102 are approximately perpendicular. For example, the angle between the sliding direction of the mobile photovoltaic panel and the extension direction of the first guide rail 102 can range from 85° to 95°.

[0188] With this arrangement, when the photovoltaic assembly is fully deployed, it requires less space in the extension direction of the first rail 102. Furthermore, with this arrangement, by shortening the lever arm, the force exerted by the photovoltaic panel unit 2 on the second rail 103 is reduced, thereby improving the stability of the photovoltaic assembly in the deployed state and reducing the probability of failure of the second rail 103 in the photovoltaic assembly due to excessive force.

[0189] When the photovoltaic module in this embodiment is in use, Figure 2-Figure 4 As shown, the photovoltaic panel unit 2 is first controlled to move relative to the first guide rail 102, so that the photovoltaic assembly is moved from the folded state (such as Figure 2 ) into an intermediate state (such as Figure 3 ), and then control the mobile photovoltaic panel to move relative to the photovoltaic panel bracket 201, so that the photovoltaic panel unit 2 is transformed from the overlapping state to the unfolded state, thereby making the photovoltaic assembly in the unfolded state (such as Figure 4 ).

[0190] As described above, in this embodiment, after the photovoltaic panel unit 2 moves relative to the first guide rail 102 to initially increase the light receiving area of ​​the photovoltaic assembly, the photovoltaic panel unit 2 can be further unfolded to further increase the light receiving area of ​​the photovoltaic assembly.

[0191] For ease of description, the photovoltaic panel unit 2 that is movably connected to the first guide rail 102 is referred to as a mobile photovoltaic panel unit, and the photovoltaic panel unit 2 that is fixedly mounted on the photovoltaic support 1 is referred to as a fixed photovoltaic panel unit. The photovoltaic panel support 201 that is movably connected to the photovoltaic support 1 is referred to as a mobile photovoltaic panel support.

[0192] In some embodiments, a limiting structure 3 is set between the mobile photovoltaic panel unit and the photovoltaic bracket 1, that is, a limiting structure 3 is set between the mobile photovoltaic panel bracket and the photovoltaic bracket 1; the limiting structure 3 is used to limit the movement of the mobile photovoltaic panel unit relative to the photovoltaic bracket 1, so as to improve the movement accuracy of the mobile photovoltaic panel unit and avoid the mobile photovoltaic panel unit from derailing during the movement, thereby reducing the failure rate of the photovoltaic module.

[0193] In an exemplary embodiment, Figure 8 As shown, the limiting structure 3 includes a first limiting block 301 and a second limiting block 302. The first limiting block 301 is provided on the mobile photovoltaic panel unit (specifically, it can be provided on the mobile photovoltaic panel support) and can move along the extension direction of the first guide rail 102 with the mobile photovoltaic panel unit; the second limiting block 302 is provided on the photovoltaic support 1 and is located on the moving path of the first limiting block 301.

[0194] Under this setting, when the photovoltaic assembly switches between the expanded state and the folded state, the first limit block 301 can move along the extension direction of the first guide rail 102 with the mobile photovoltaic panel unit, and when the mobile photovoltaic panel unit moves to the preset position, the first limit block 301 can abut against the second limit block 302, thereby preventing the mobile photovoltaic panel unit from continuing to move, so as to ensure that the mobile photovoltaic panel unit will not derail.

[0195] The above-mentioned movement of the photovoltaic panel to the preset position includes but is not limited to moving the photovoltaic panel unit relative to the photovoltaic bracket 1 when the photovoltaic assembly is in the middle state.

[0196] Further preferably, two second limit blocks 302 are provided in the extension direction of the first track, and the two limit blocks are spaced apart, and the first limit block 301 is provided between the two limit blocks. In this way, when the photovoltaic assembly is deployed to the intermediate state, the limit structure 3 can limit the continued movement of the mobile photovoltaic panel unit; when the photovoltaic assembly is retracted to the retracted state, the limit structure 3 can also limit the continued movement of the mobile photovoltaic panel unit. This can better prevent the mobile photovoltaic panel unit from derailing.

[0197] Furthermore, when the first limit block 301 and the second limit block 302 are in contact, that is, when the mobile photovoltaic panel unit moves to a preset position, a locking structure can be set to limit the movement of the first limit block 301 relative to the second limit block 302, thereby making the mobile photovoltaic panel unit stationary relative to the photovoltaic bracket 1.

[0198] In specific implementation, the above-mentioned locking structure can be a bolt, or an electromagnetic component, etc., and this application does not make specific limitations on this. In specific implementation, adaptive design can be carried out according to needs.

[0199] In some embodiments, as Figures 9-11 As shown, the mobile photovoltaic panel unit is movably connected to the first guide rail 102 via a guide wheel set.

[0200] In this arrangement, the friction between the guide wheel assembly and the first guide rail 102 is rolling friction. This reduces resistance to the movement of the mobile photovoltaic panel unit relative to the photovoltaic support 1, thereby facilitating adjustment of the light-receiving area of ​​the photovoltaic module. Furthermore, it reduces wear on the mobile photovoltaic panel unit and / or the first guide rail 102.

[0201] Further, continue as Figures 9-11 As shown, the photovoltaic bracket 1 further includes a limiting beam 104 fixedly connected to the bracket body 101. The limiting beam 104 is arranged parallel to and spaced apart from the first guide rail 102, and is used to limit the movement of the guide wheel assembly in a direction perpendicular to the support surface of the first guide rail 102. In this arrangement, the limiting wheel assembly is clamped between the limiting beam 104 and the first guide rail 102, thereby preventing the mobile photovoltaic panel unit from falling due to one side being suspended during the deployment of the photovoltaic assembly.

[0202] On the basis that the photovoltaic assembly includes the above-mentioned guide wheel group, in some embodiments, the guide wheel group includes a plurality of guide wheels 4, which are all rotatably set on the photovoltaic panel bracket 201 and are spaced apart along the extension direction of the first guide rail 102; and the gap between adjacent guide wheels 4 close to the side of the first limit block 301 is smaller than the gap between adjacent guide wheels 4 away from the side of the first limit block 301.

[0203] Understandably, Figure 2As shown, when the mobile photovoltaic panel unit moves along the first guide rail 102 to increase the light-receiving area of ​​the photovoltaic component, as the mobile photovoltaic panel unit moves, the overlap between the mobile photovoltaic panel unit and the photovoltaic bracket 1 will become smaller and smaller, or in other words, the coordination between the guide wheel group and the first guide rail 102 will become smaller and smaller.

[0204] Based on the above situation, in this embodiment, by setting the gap between the adjacent guide wheels 4 on the side close to the first limit block 301 to be smaller than the gap between the adjacent guide wheels 4 on the side away from the first limit block 301, it is beneficial to increase the movement amount of the mobile photovoltaic panel unit while ensuring that the matching amount between the guide wheel group and the first guide rail 102 meets the connection requirements between the mobile photovoltaic panel unit and the photovoltaic bracket 1.

[0205] In some embodiments, as Figure 10 and Figure 11 As shown, a limiting wheel group is provided on the bracket body 101, and the limiting wheel group includes a plurality of limiting wheels 5 distributed along the extension direction of the first guide rail 102; and all the limiting wheels 5 are rotatably provided on the bracket body 101, and the treads of all the limiting wheels 5 can abut against the photovoltaic panel bracket 201.

[0206] The setting of the limiting wheel group can constrain the moving direction of the mobile photovoltaic panel unit during the movement relative to the photovoltaic bracket 1, thereby preventing the mobile photovoltaic panel unit from deviating during the movement and ensuring the normal movement of the mobile photovoltaic panel unit.

[0207] In a preferred embodiment, the mobile photovoltaic panel unit is provided with limiting wheel groups on both sides of its moving direction. In this way, the limiting wheel groups cooperate with the above-mentioned guide wheel groups so that the moving direction of the mobile photovoltaic panel unit can only be the extension direction of the first guide rail 102, so as to further ensure the normal movement of the mobile photovoltaic panel unit.

[0208] In some embodiments, the second guide rail 103 is hinged to the bracket body 101 via a rotating shaft, with the axis of the rotating shaft perpendicular to the support surface of the second guide rail 103. This reduces the probability that the second guide rail 103 will move relative to the photovoltaic bracket 1 at the hinged position due to force after the photovoltaic panel unit 2 moves onto the second guide rail 103. In other words, the above arrangement in this embodiment helps to improve the supporting capacity of the second guide rail 103.

[0209] In an exemplary embodiment, Figure 5-Figure 7 as well as Figure 9As shown, a vertical rod 105 is provided on the side of the second guide rail 103 away from its supporting surface, and is hingedly connected to the photovoltaic bracket 1 via the vertical rod 105. A supporting diagonal rod 106 is connected to the side of the vertical rod 105 away from the second guide rail 103. In the extension direction of the second guide rail 103, the supporting diagonal rod 106 is connected to the side of the second guide rail 103 away from the vertical rod 105. Consequently, the second guide rail 103, the vertical rod 105, and the supporting diagonal rod 106 cooperate to form a stable triangular structure. This reduces the probability of deformation of the second guide rail 103 after the photovoltaic panel unit 2 moves onto the second guide rail 103.
