Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, specifically to a photovoltaic energy storage device. Background Technology

[0002] Traditional fixed photovoltaic (PV) modules are limited by installation location, large footprint, and poor flexibility, making it difficult to meet energy demands in certain specific scenarios. Against this backdrop, mobile PV modules have emerged, becoming an important development direction in the PV technology field due to their flexible deployment, rapid response, and efficient utilization of solar energy resources.

[0003] The light-receiving surface of a photovoltaic (PV) module refers to the surface within the PV module that receives sunlight to convert solar energy into electrical energy. The size of the light-receiving surface directly affects the energy conversion efficiency of the PV module. However, a larger light-receiving surface results in a larger supporting structure for the PV module, which in turn leads to a larger overall size of the PV-energy storage device, making it less convenient for transporting and moving the device.

On the other hand, during the conversion between the extended and retracted states of the PV modules using the deployment and retraction brackets, because the PV panels move in different directions, more PV panels can overlap in the retracted state, making the structure of the PV modules more compact and smaller in volume. Understandably, the smaller the volume of the PV modules, the smaller the supporting structure can be, further reducing the overall volume of the PV energy storage device. With this configuration, the volume requirement for the traction equipment can be greatly reduced when moving the PV energy storage device, thus facilitating its transport and relocation.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] like Figures 1-17 As shown, the photovoltaic energy storage device in this embodiment includes a support structure 7 and photovoltaic modules, wherein:

[0078] Support structure 7 is the main structure used to support the photovoltaic modules.

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

[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] In the above structure, the photovoltaic module converts light energy into electrical energy, and then the electrical energy is directly delivered 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] In a further preferred embodiment, 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 to supply the load.

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

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

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

[0086] like Figures 13-16 As shown, in this embodiment, the photovoltaic module is set on the top of the support structure 7 and includes a retractable bracket and multiple photovoltaic panels 202 set on the retractable bracket. The retractable bracket can drive at least some of the photovoltaic panels 202 to move in different directions to increase the light-receiving area of ​​the photovoltaic module (the light-receiving area of ​​the photovoltaic module refers to the area of ​​the photovoltaic module that is not blocked and can receive solar radiation, that is, the sum of the areas of the unblocked parts of the light-receiving surface of all photovoltaic panel units 2).

[0087] The aforementioned mounting bracket refers to a bracket structure that can be used to change the relative positions of multiple photovoltaic panels 202 to increase or decrease the light-receiving area of ​​the photovoltaic module.

[0088] In practical implementation, the way the deployment and retraction bracket changes the relative positions of multiple photovoltaic panels 202 can be by causing some photovoltaic panels 202 to slide relative to other photovoltaic panels 202, or by causing some photovoltaic panels 202 to rotate relative to other photovoltaic panels 202. Of course, this application is not limited to this. For example, the deployment and retraction bracket can change the relative positions of multiple photovoltaic panels 202 by causing the photovoltaic panels 202 to rotate around a certain axis.

[0089] Furthermore, in practical implementation, the deployment and take-off support can be constructed from weather-resistant metal materials (i.e., the ability to withstand various climatic conditions and their effects in the natural environment), such as aluminum alloys and / or galvanized steel. Of course, this application is not limited to this; in practical implementation, the deployment and take-off support can also be made of ordinary carbon steel with a rust-proof surface treatment, or composite materials such as carbon fiber reinforced plastics.

[0090] When performing photoelectric conversion using the photovoltaic-storage device in this embodiment, the device is first moved to a preset position. Then, a retractable support frame is used to move the photovoltaic panels 202 in different directions, thereby reducing the overlap between different photovoltaic panels 202 and increasing the light-receiving area of ​​the photovoltaic module to ensure the photoelectric conversion efficiency of the photovoltaic module. When the photovoltaic-storage device needs to be moved, the retractable support frame is first used to retract the photovoltaic panels 202 towards 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, during the transition between the extended and retracted states of the photovoltaic modules using the deployment and retraction bracket, the photovoltaic panels 202 move in different directions. In the retracted state, more photovoltaic panels 202 overlap, resulting in a more compact and smaller structure. Consequently, the smaller size of the photovoltaic modules allows for a corresponding reduction in the size of the support structure 7, further minimizing the overall volume of the photovoltaic storage device. This configuration significantly reduces the volume requirement for the traction equipment 9 during the transfer of the photovoltaic storage device, making it easier to move and transport the device.

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

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

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

[0095] Specifically, the lifting structure 11 is located 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. This improves the space utilization of the cavity of the support structure 7, thereby further improving the overall structural compactness of the optical storage device and reducing its volume.

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

[0097] In alternative embodiments, such as Figure 16 As shown, the lifting structure 11 can be a hydraulic rod, with one end hinged to the base plate 701 of the support structure 7 and the other end hinged to the photovoltaic bracket 1 of the photovoltaic module. Thus, the angle of the photovoltaic module can be adjusted by extending and retracting 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] Furthermore, regarding the number of lifting structures 11, the design can be adapted to the specific implementation, and this application does not impose a specific limitation on this. However, it should be noted that when multiple lifting structures 11 are installed, the multiple lifting structures 11 should be able to start and stop synchronously.

[0100] The locking component 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. In this way, undesirable automatic adjustments to the tilt angle of the photovoltaic module can be avoided, which helps the photovoltaic module maintain the optimal tilt angle and improve the photoelectric conversion efficiency of the photovoltaic module.

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

[0102] Slider 1201 is slidably mounted on support structure 7; specifically, as follows: Figure 17 As shown, the slider 1201 is slidably mounted on the outer wall 702 of the frame 602.

[0103] One end of the connecting rod 1202 is hinged to the photovoltaic module, and the other end is hinged to the slider 1201. In this way, the linkage between the photovoltaic module and the slider 1201 can be realized by using the connecting rod 1202. That is, when the tilt angle of the photovoltaic module 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 tilt angle of the photovoltaic module by fixing the position of the slider 1201 relative to the outer wall 702.

[0104] A locking element is provided on the slider 1201 and / or the support structure 7, and is used to fix the position of the slider 1201 relative to the support structure 7.

[0105] For example, in a specific implementation, the locking element can be a locking screw, which is threaded onto the slider 1201 and can abut against the outer wall 702. Of course, this application is not limited to this; for example, the locking element can also be a snap-fit ​​element that can achieve snap-fit ​​fixation between 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, which includes a guide groove and a protrusion. The guide groove is located on one of the support structure 7 and the slider 1201 and extends along the height direction of the support structure 7; the protrusion is located on the other of the support structure 7 and the slider 1201 and is slidably connected to the guide groove. In this way, the movement of the slider 1201 on the outer wall 702 is restricted by the guide groove and the protrusion.

[0107] In some embodiments, the bottom of the support structure 7 is provided with a roller assembly for moving the support structure 7.

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

[0109] The roller assembly is a structure designed to facilitate the movement of the support structure 7, such as... Figures 14-16 As shown, the roller assembly includes multiple rollers 703, all of which are rotatably mounted on the bottom of the support structure 7, and the tread surfaces of the rollers 703 (i.e., the surfaces of the rollers 703 that surround the axis of rotation of the rollers 703 and are parallel to the axis of rotation 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 component is provided on the outer periphery of the support structure 7. This support component is used to support the support structure 7 and enables the roller 703 to be suspended in the air.

[0111] Once the optical storage device is moved to the designated position, the support assembly is adjusted to suspend the roller 703, and then the support assembly replaces the roller 703 to support the support structure 7. This effectively improves the stability of the support.

[0112] In some embodiments, the support structure 7 includes multiple support beams that extend outward (i.e., away from the support structure 7) parallel to the base plate 701 of 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. Thus, when the optical storage device is in a retracted state, the outwardly extending end of the support beam can be retracted, and / or the support beam can be rotated to reduce the impact of the support beam on the volume of the optical storage device in the retracted state.

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

[0115] When it is necessary to use the support components to support the photovoltaic storage equipment, simply control the telescopic part to move away from the chassis frame until the roller 703 is suspended in the air.

[0116] It should be understood that the support column 8, including the fixed part and the telescopic part, is only an exemplary implementation of the support column 8, but the embodiments of this application are not limited thereto. For example, the support column 8 can also be a rigid support structure 7 that cannot be telescopic, and the support column 8 is rotatably mounted on the chassis frame.

[0117] like Figures 13-16 As shown, the photovoltaic energy storage device also includes a carrier trolley 6, which is a carrier structure for facilitating long-distance transportation of photovoltaic modules; while the support structure 7 is a frame structure for facilitating short-distance adjustment of photovoltaic modules.

[0118] In this embodiment, when the photovoltaic storage device needs to be transported over long distances, the support structure 7 and the carrier trolley 6 are in an assembled state. When a short-distance adjustment of the installation position of the photovoltaic storage device is required, the support structure 7 and the carrier trolley 6 can be separated. This avoids the inconvenience caused by the large turning radius of the carrier trolley 6, thus making the position adjustment of the photovoltaic storage device more flexible.

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

[0120] Wheel 601 is used to facilitate the movement of the trolley 6.

[0121] The frame 602 is a support structure 7 for forming a load-bearing surface, and the frame 602 is provided with a travel connection structure for connecting the wheel 601, so as to connect the wheel 601 and the frame 602.

[0122] The trailer 603 has a towing end and a fixed end. The fixed end is fixedly connected to the frame 602, and the towing end is provided with a towing structure for connecting the towing equipment 9 (e.g., a vehicle). The trailer 603 is used to facilitate the connection between the trolley 6 and the towing equipment 9, thereby facilitating the movement of the optical storage equipment.

[0123] Furthermore, the carrier trolley 6 also includes a ramp 605, one end of which is hinged to the side of the frame 602 away from the trailer 603, and the other end can be attached to the surface supporting the optical storage device. In this way, after the optical storage device reaches the preset position, the vehicle frame 602 and other structures can be loaded and unloaded through the ramp 605, thereby facilitating the loading and unloading of the support structure 7 and other structures.

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

[0125] Furthermore, the number of inclined pedals 605 can be one or two. This application does not specifically limit this number, and adaptive designs can be made as needed during implementation.

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

[0127] Furthermore, in addition to the aforementioned inclined pedal 605, the carrying trolley 6 also includes a winch 606, which is fixedly mounted on the side of the frame 602 near the trailer 603 and can at least be used to move the traction support structure 7.

[0128] For example, such as Figures 14-16 As shown, the winch 606 includes a fixed frame, a fixed pulley rotatably mounted on the fixed frame, a cable wound on the fixed pulley, and a drive structure for driving the fixed pulley to rotate.

[0129] Under the above configuration, during operation, after fixing the free end of the cable to the support structure 7, the drive structure is activated to wind up and unwind the cable, and the support structure 7 can be loaded and unloaded using the winch 606.

[0130] Furthermore, for ease of description, the first side is used to refer to the side of the frame 602 connected to the inclined foot pedal 605, and the second side is used to refer to the side of the frame 602 connected to the trailer 603.

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

[0132] By setting the limiting track 10, the movement direction of the support structure 7 on the bearing surface of the frame 602 is restricted, which can effectively prevent the movement direction of the support structure 7 from deviating during the loading and unloading process, thus preventing the support structure 7 from falling off the bearing trolley 6.

[0133] Furthermore, the limiting track 10 is a limiting groove formed in the supporting structure 7, and the tread surface of the roller 703 abuts against the bottom of the limiting groove. With this arrangement, the limiting track 10 can enhance the limiting effect on the supporting structure 7, and further reduce the probability of the supporting structure 7 deviating on the trolley 6.

[0134] For example, the aforementioned limiting groove can be formed by parallel and spaced protrusions on the frame 602. Alternatively, it can be formed by a recess in the bearing surface of the frame 602.

[0135] Furthermore, based on the aforementioned carrier trolley 6, such as Figures 14-16 As shown, wheel 601 includes a supporting traveling wheel 6011 and a supporting guide wheel 6012, wherein:

[0136] The supporting walking wheel 6011 is connected to the walking connection structure through the shock absorption component and is set near the first side of the frame 602, that is, near the side of the frame 602 away from the trailer 603.

[0137] In practical implementation, the shock absorption components can be adapted to meet specific needs. For example, the shock absorption components mentioned above can be a shock absorption structure formed by multiple leaf springs, or a shock absorption structure formed by multiple hydraulic shock absorbers, or a shock absorption system formed by air springs.

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

[0139] More specifically, such as Figures 14-16As shown, the extension direction of the support rod 604 is perpendicular to the bearing surface of the bearing trolley 6. The support guide wheel 6012 is rotatably mounted on the bottom end of the support rod 604 (that is, the end of the support rod 604 near the ground) through a shaft structure, and the tread of the support guide wheel 6012 can abut against the support surface of the photovoltaic storage device.

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

[0141] Furthermore, as mentioned above, the supporting walking wheel 6011 and the supporting guide wheel 6012 in this embodiment are arranged on opposite sides of the carrying trolley 6. This arrangement helps to distribute the load and thus improves the stability of the support.

[0142] It should be understood that the above is only one exemplary implementation of the support guide wheel 6012, but this application is not limited to this. For example, in specific implementations, the support rod 604 can also be fixedly mounted on the frame 602 or the trailer 603, and the support guide wheel 6012 can be set as a caster wheel. This can also achieve the purpose of enabling the optical storage device to self-adjust its direction of movement.

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

[0144] In some embodiments, the optical storage device further includes a wind speed meter 13 and an alarm light 14, wherein:

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

[0146] When the photovoltaic and energy storage equipment is in use, the anemometer 13 can monitor the wind speed level of the environment in real time. When the wind speed reaches the preset level, the alarm light 14 will be activated to remind the staff to take appropriate measures (such as strengthening the support of the photovoltaic modules or shutting down the photovoltaic and energy storage equipment). This will help prevent damage to the photovoltaic and energy storage equipment in strong winds.

[0147] In some embodiments, the deployment and retraction support includes a photovoltaic support 1 and a plurality of photovoltaic panel supports 201, wherein the photovoltaic support 1 is connected to the support structure 7; all photovoltaic panel supports 201 are provided with a plurality of photovoltaic panels 202 that can be deployed along a first direction; and at least one photovoltaic panel support 201 is movably connected to the photovoltaic support 1 so as to drive the photovoltaic panel 202 to move along a second direction; wherein the first direction and the second direction satisfy a perpendicular condition (that is, the sliding direction of the moving 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 moving photovoltaic panel and the extension direction of the first guide rail 102 can be in the range of 85°~95°).

[0148] Under the above-mentioned structure of the retractable support, when it is necessary to change the photovoltaic energy storage device from the retracted state to the extended state, the photovoltaic panel support 201 is first controlled to move relative to the photovoltaic support 1 so that the photovoltaic energy storage device changes from the retracted state to the intermediate state. Then, the photovoltaic panel 202 on the photovoltaic panel support 201 is controlled to unfold along the first direction, thereby changing the photovoltaic energy storage device from the intermediate state to the extended state.

[0149] The photovoltaic panel bracket 201 and the photovoltaic bracket 1 can be connected by a sliding connection or a hinged connection. This application does not impose specific limitations on this.

[0150] Furthermore, for ease of understanding, the following description uses the sliding connection between the photovoltaic panel bracket 201 and the photovoltaic bracket 1 as an example to illustrate the specific setting of the extension and retraction bracket. For ease of description, in this embodiment, one photovoltaic panel bracket 201 and multiple photovoltaic panels 202 disposed on the photovoltaic panel bracket 201 are referred to as a photovoltaic panel unit 2.

[0151] like Figures 1-12 As shown, the photovoltaic module includes a photovoltaic support frame 1 and multiple photovoltaic panel units 2. Wherein:

[0152] The photovoltaic bracket 1 is a structural system used for installing, fixing and adjusting the position of the photovoltaic panel unit 2.

[0153] like Figures 5-7 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 aforementioned support body 101 is the core load-bearing structure of the photovoltaic support 1, used to provide basic support for the entire photovoltaic module.

[0155] Optionally, the support body 101 can be a frame structure formed by multiple crossbeams, longitudinal beams, etc. The aforementioned crossbeams and longitudinal beams are preferably made of metal materials with strong weather resistance and high strength.

[0156] Optionally, the support body 101 can also be provided with a box-like structure with an opening.

[0157] The first guide rail 102 and the second guide rail 103 are both structures in the photovoltaic bracket 1 used to adjust 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 follows Figures 5-7 As shown, in this embodiment, the first guide rail 102 is fixedly connected to the support body 101. The second guide rail 103 is movably connected to the support body 101.

[0159] This application does not specifically limit the method of fixing the first guide rail 102 to the bracket body 101. For example, the first guide rail 102 and the bracket body 101 can be connected by a connection structure such as bolts; or, the first guide rail 102 can also be welded to the bracket body 101.

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

[0161] Furthermore, based on the aforementioned movable connection between the second guide rail 103 and the support 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 support body 101, the second guide rail 103 can switch between the aforementioned first state and second state.

[0162] In the first state, the second guide rail 103 is located on one side of the width direction of the first guide rail 102, or the extension direction of the second guide rail 103 has a non-zero angle with the extension direction of the first guide rail 102. That is, in the first state described above, 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] Photovoltaic panel unit 2 is the core component for converting light energy into electrical energy.

[0165] In this embodiment, multiple 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 this embodiment, 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 are fixedly mounted on the bracket body 101.

[0166] Furthermore, the photovoltaic panel unit 2, which is movably connected to the first guide rail 102, can move 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 essentially an extension of the first guide rail 102. That is, the photovoltaic module in this embodiment forms a foldable track structure by setting the first guide rail 102 and the second guide rail 103. When the photovoltaic module needs to be transported, the second guide rail 103 is controlled to be in the first state, making the structure of the photovoltaic module more compact so that the photovoltaic module can have a smaller volume. When the photovoltaic module 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 increases, thereby increasing the effective power generation area of ​​the photovoltaic module and making the photovoltaic module have a higher energy conversion efficiency.

[0168] It should be noted that the number of photovoltaic panel units 2 can be adapted to the specific implementation as needed, and this application does not impose any specific restrictions on this.

[0169] For example, such as Figures 1-3 As shown, photovoltaic panel unit 2 can be configured as three units, in a direction perpendicular to the light-receiving surface of photovoltaic panel unit 2 (i.e., Figure 1 In the X direction, three photovoltaic panel units 2 are distributed sequentially. 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; and the two photovoltaic panel units 2 movably connected to the first guide rail 102 move along the extension direction of the first guide rail 102, and the moving directions are opposite.

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

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

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

[0173] The light-receiving area of ​​the photovoltaic panel unit 2 mentioned above refers to the area of ​​the unshaded part of the photovoltaic panel unit 2 that can receive solar radiation, which is the total area of ​​the unshaded part of the light-receiving surface of all photovoltaic panels 202.

[0174] Based on the aforementioned photovoltaic panel unit 2, which includes a movable photovoltaic panel, the photovoltaic panel unit 2 has an overlapping state and an unfolded state. Furthermore, 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. Wherein:

[0175] The overlapping state refers to the fact that, in the direction perpendicular to the light-receiving surface, the overlap between different photovoltaic panels 202 is not less than 80%. That is, in the direction perpendicular to the light-receiving surface, at least 80% of the projection of one photovoltaic panel 202 falls on the adjacent photovoltaic panel 202. At this time, because the light-receiving surface of the photovoltaic panel 202 is largely blocked, the light-receiving area of ​​the photovoltaic panel unit 2 is relatively small.

[0176] The "unfolded state" refers to a situation where, in the direction perpendicular to the light-receiving surface, the overlap between different photovoltaic panels 202 is less than 20%. That is, in the direction perpendicular to the light-receiving surface, at most 20% of the projection of one photovoltaic panel unit 2 falls on the adjacent photovoltaic panel 202. At this time, since 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 relatively large.

[0177] It is understood that the aforementioned overlap amounts of different photovoltaic panels 202 in the overlapping state and in the unfolded state are not intended to limit this application; that is, in specific implementations, the overlap amounts of different photovoltaic panels 202 in the overlapping state and in the unfolded 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 components in 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 earlier, the movable photovoltaic panel is movably connected to the photovoltaic panel bracket 201. This movable connection includes, but is not limited to, hinged or sliding connections.

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

[0180] Specifically, the movable 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 movable photovoltaic panel.

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

[0182] The aforementioned auxiliary support structure 7 can be a support structure 7 movably connected to the photovoltaic panel bracket 201, or it can be a support structure 7 detachably connected to the photovoltaic panel bracket 201. This application does not specifically limit this. However, it should be ensured that, in the overlapping state of the photovoltaic panel units 2, the auxiliary support structure 7 should not affect the movement of the photovoltaic panel units 2 on the first guide rail 102.

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

[0184] For example, the movable photovoltaic panel can be slidably connected to the photovoltaic panel bracket 201 via a slide rail.

[0185] Specifically, the slide rail includes an inner rail and an outer rail; the outer rail is a strip-shaped structure with grooves, and the extension direction of the grooves is consistent with the length direction of the outer rail. The side of the outer rail away from the grooves is connected to the photovoltaic panel bracket 201. The inner rail can slide in the grooves of the outer rail and is connected to the movable photovoltaic panel.

[0186] Further preferably, a structure such as ball bearings can be provided between the inner and outer rails to reduce friction.

[0187] Furthermore, based on the sliding connection of the movable photovoltaic panel to the photovoltaic panel bracket 201, in a preferred embodiment, such as... Figure 12 As shown, the sliding direction of the movable photovoltaic panel and the extending direction of the first guide rail 102 satisfy the perpendicular condition. That is, the sliding direction of the movable photovoltaic panel and the extending direction of the first guide rail 102 are approximately perpendicular. For example, the angle between the sliding direction of the movable photovoltaic panel and the extending direction of the first guide rail 102 can be in the range of 85°~95°.

[0188] In this configuration, when the photovoltaic module is fully extended, the space required for it in the extension direction of the first guide rail 102 is smaller. Furthermore, this configuration reduces the force exerted by the photovoltaic panel unit 2 on the second guide rail 103 by shortening the lever arm, thereby improving the stability of the photovoltaic module in the extended state and reducing the probability of the second guide rail 103 in the photovoltaic module malfunctioning due to excessive force.

[0189] When the photovoltaic module in this embodiment is used, such as Figures 2-4 As shown, first control the photovoltaic panel unit 2 to move relative to the first guide rail 102, so that the photovoltaic module moves from the retracted state (e.g., Figure 2 ) transforms into an intermediate state (such as Figure 3 Then, control the moving photovoltaic panel to move relative to the photovoltaic panel support 201, so that the photovoltaic panel unit 2 changes from an overlapping state to an unfolded state, thereby putting the photovoltaic module in an unfolded state (e.g., 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 module, the photovoltaic panel unit 2 can be further expanded, thereby further increasing the light-receiving area of ​​the photovoltaic module.

[0191] For ease of description, the photovoltaic panel unit 2 movably connected to the first guide rail 102 will be referred to as the movable photovoltaic panel unit, and the photovoltaic panel unit 2 fixedly mounted on the photovoltaic bracket 1 will be referred to as the fixed photovoltaic panel unit. The photovoltaic panel bracket 201 movably connected to the photovoltaic bracket 1 will be referred to as the movable photovoltaic panel bracket.

[0192] In some embodiments, a limiting structure 3 is provided between the movable photovoltaic panel unit and the photovoltaic support 1, that is, a limiting structure 3 is provided between the movable photovoltaic panel support and the photovoltaic support 1; the limiting structure 3 is used to restrict the movement of the movable photovoltaic panel unit relative to the photovoltaic support 1, so as to improve the movement accuracy of the movable photovoltaic panel unit and prevent the movable photovoltaic panel unit from derailing during movement, thereby reducing the failure rate of the photovoltaic module.

[0193] In an exemplary implementation, such as 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 disposed on the movable photovoltaic panel unit (specifically, it can be disposed on the movable photovoltaic panel bracket) and can move along the extension direction of the first guide rail 102 with the movable photovoltaic panel unit; the second limiting block 302 is disposed on the photovoltaic bracket 1 and is located on the moving path of the first limiting block 301.

[0194] In this configuration, when the photovoltaic module switches between the unfolded state and the retracted state, the first limiting block 301 can move along the extension direction of the first guide rail 102 with the moving photovoltaic panel unit. When the moving photovoltaic panel unit moves to the preset position, the first limiting block 301 can abut against the second limiting block 302, thereby preventing the moving photovoltaic panel unit from continuing to move, so as to ensure that the moving photovoltaic panel unit will not derail.

[0195] The aforementioned movement of the movable photovoltaic panel to the preset position includes, but is not limited to, the position of the movable photovoltaic panel unit relative to the photovoltaic support 1 when the photovoltaic module is in the intermediate state.

[0196] Further preferably, two second limiting blocks 302 are provided in the extension direction of the first track, and the two limiting blocks are spaced apart. A first limiting block 301 is positioned between the two limiting blocks. Thus, when the photovoltaic module is unfolded to its intermediate state, the limiting structure 3 can restrict the movement of the moving photovoltaic panel unit; when the photovoltaic module is retracted to its retracted state, the limiting structure 3 can also restrict the movement of the moving photovoltaic panel unit. This better prevents the moving photovoltaic panel unit from derailing.

[0197] Furthermore, when the first limiting block 301 and the second limiting block 302 come into contact, that is, when the movable photovoltaic panel unit moves to the preset position, a locking structure can be set to restrict the movement of the first limiting block 301 relative to the second limiting block 302, thereby making the movable photovoltaic panel unit stationary relative to the photovoltaic support 1.

[0198] In specific implementation, the locking structure described above can be a bolt, or it can be an electromagnetic component, etc. This application does not make specific limitations on this. In specific implementation, an adaptive design can be made as needed.

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

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

[0201] Furthermore, continuing as Figures 9-11 As shown, the photovoltaic support 1 also includes a limiting beam 104 fixedly connected to the support body 101. The limiting beam 104 is 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 configuration, the limiting wheel assembly is held between the limiting beam 104 and the first guide rail 102, thereby preventing the moving photovoltaic panel unit from falling due to one side being suspended during the photovoltaic module deployment process.

[0202] Based on the photovoltaic module including the above-mentioned guide wheel group, in some embodiments, the guide wheel group includes multiple guide wheels 4, all of which are rotatably mounted on the photovoltaic panel bracket 201 and are distributed at intervals along the extension direction of the first guide rail 102; and the gap between adjacent guide wheels 4 on the side closer to the first limiting block 301 is smaller than the gap between adjacent guide wheels 4 on the side farther from the first limiting block 301.

[0203] Understandable, such as Figure 2As shown, when the movable photovoltaic panel unit moves along the first guide rail 102 to increase the light-receiving area of ​​the photovoltaic module, the overlap between the movable photovoltaic panel unit and the photovoltaic support 1 will become smaller and smaller as the movable photovoltaic panel unit moves, or in other words, the amount of cooperation between the guide wheel assembly and the first guide rail 102 will become smaller and smaller.

[0204] Based on the above, in this embodiment, by setting the gap of the adjacent guide wheel 4 on the side closer to the first limiting block 301 to be smaller than the gap of the adjacent guide wheel 4 on the side farther from the first limiting block 301, it is beneficial to increase the movement of the mobile photovoltaic panel unit while ensuring that the fit 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, such as Figure 10 and Figure 11 As shown, a set of limiting wheels is provided on the bracket body 101. The set of limiting wheels includes multiple limiting wheels 5 distributed along the extension direction of the first guide rail 102. All the limiting wheels 5 are rotatably mounted on the bracket body 101, and the tread surfaces of all the limiting wheels 5 can abut against the photovoltaic panel bracket 201.

[0206] The setting of the limit wheel group can constrain the movement direction of the movable photovoltaic panel unit during its movement relative to the photovoltaic support 1. This prevents the movable photovoltaic panel unit from deviating during movement, thereby ensuring the normal movement of the movable photovoltaic panel unit.

[0207] In a preferred embodiment, the movable photovoltaic panel unit is provided with limit wheel sets on both sides of its movement direction. In this way, the limit wheel sets, together with the guide wheel sets, ensure that the movement direction of the movable photovoltaic panel unit is limited to the extension direction of the first guide rail 102, so as to further ensure the normal movement of the movable photovoltaic panel unit.

[0208] In some embodiments, the second guide rail 103 is hinged to the support body 101 via a pivot, and the axis of the pivot is 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 support 1 at the hinged position due to force after the photovoltaic panel unit 2 moves to it. In other words, the above-described arrangement in this embodiment helps to improve the support capacity of the second guide rail 103.

[0209] In an exemplary implementation, such as Figures 5-7 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 hinged 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, and the supporting diagonal rod 106 is connected to the side of the second guide rail 103 away from the vertical rod 105 in the extending direction of the second guide rail 103. This allows the second guide rail 103, the vertical rod 105, and the supporting diagonal rod 106 to 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 to the second guide rail 103.
