[0058] The application will be described in detail below in combination with the drawings and specific embodiments.

[0059] The embodiment provides a solar unmanned aerial vehicle flexible photovoltaic module paving device, as shown in Figures 1-3As shown, the device includes a horizontally positioned base 10, a support 20 slidably connected to the base 10, and a clamping part 30 that cooperates with the drone 40. The support 20 can not only adjust its position to cooperate with the wings of the drone 40, but also supports and fixes the wings of the solar-powered drone 40. The support 20 is mounted on the base 10 and can slide horizontally along the width of the base 10 and move vertically up and down. The clamping part 30 cooperates with the wing ribs 41 and photovoltaic modules 42 in the drone 40. It is equipped with a rigid skin 31 and an adsorption assembly. The rigid skin 31 is detachably connected to the wing ribs 41 for placing the photovoltaic modules 42. The adsorption assembly is located on both sides of the rigid skin 31 and the photovoltaic modules 42. The adsorption assembly has adjustable adsorption heat-pressing capacity to press against the photovoltaic modules 42 and melt the adhesive layer 43 to adhere the photovoltaic modules 42 to the wing ribs 41.

[0060] In this application, the wings of the solar-powered drone 40 feature a flexible, skeletal design structure made of pure carbon fiber. The photovoltaic module 42 is a fully flexible design, with individual cells made of one of the following materials: flexible gallium arsenide, crystalline silicon, or perovskite. The radius of curvature of the photovoltaic module 42 is no greater than 500 mm, and its performance degradation after 1000 bends is no greater than 5%. The adhesive layer 43 is a flexible thin-film adhesive layer with a thickness of 50-200 μm. It has a certain initial tack at room temperature and can bond well with the carbon fiber material on the upper surface of the flexible wing ribs 41 in the solar-powered drone 40. The adhesive layer 43 begins to melt at 90°C and, after heating between 120-150°C for a certain period, can reliably bond to the bonding interface.

[0061] like Figure 4 As shown, the support 20 includes tracks 21 arranged in parallel along the width direction of the base 10, several vertical support frames 22 cooperating with the tracks 21, and upright plates 23 supported by the support frames 22. The upright plates 23 span the pairs of support frames 22 placed on the two tracks 21, meaning the upright plates 23 are arranged along the length direction of the base 10, and at least two sets of upright plates 23 are arranged in parallel to form a parallel upright plate 23 structure that can be freely adjusted in the width direction. Correspondingly, the support frames 22 are vertically adjustable frames that can be raised and lowered via guide shafts and guide sleeves. The driving method is not limited; this is common knowledge in the art and is omitted here. The upright plates 23 are provided with slots 24 for securing the wing ribs 41. Simultaneously, the top of the upright plates 23 between adjacent slots 24 is provided with a concave surface adapted to the wing belly structure to prevent interference between the top of the upright plates 23 and the belly position of the UAV 40 when the wing ribs 41 are secured by the slots 24.

[0062] The adjacent support frames 22 can adjust their positions in the horizontal width direction and / or synchronously adjust their positions in the height direction to adapt to the height or width of the wing ribs 41 of the solar unmanned aerial vehicle 40, and adjust the matching size to the appropriate position to support and fix the flexible wings of the solar unmanned aerial vehicle 40, facilitate the fixing of the wings of the solar unmanned aerial vehicle 40 on the clamping grooves 24 of the support part 20, and prevent the movement of the wings of the solar unmanned aerial vehicle 40 during paving. The base 10 is a solid metal water platform surface, which provides a stable horizontal reference surface for paving the flexible photovoltaic module 42 in the solar unmanned aerial vehicle 40, and can ensure that all parts are on the same horizontal reference surface.

[0063] As shown in Figure 3 The hard skin 31 is shaped to match the structure of the upper end surface of the wing rib 41 and is arranged on the inner wall of the adjacent wing rib 41. The hard skin 31 can be detachably fixed between the adjacent wing ribs 41 by mechanical clamps. Of course, other detachable connection methods can also be used to install the hard skin 31, which is not specifically limited and omitted in the drawings. On the premise of not affecting the cooperation of the photovoltaic module 42 and the wing, the hard skin 31 can provide ideal profile support for the paving of the flexible photovoltaic module 42. The adhesive layer 43 is arranged between the wings of the photovoltaic module 42, that is, on the upper surface of the wing rib 41.

[0064] As shown in Figures 5-6 The hard skin 31 is made of fluorine-containing plastic material, which has good release effect with the adhesive layer 43. The thickness of the hard skin 31 is 3-5 mm. Since the flexible photovoltaic module 42 is provided with a lead cable, a plurality of circular holes (omitted in the drawings) through which the cable can pass must be designed on the hard skin 31, and the diameter of the circular hole is 10-15 mm.

[0065] The adsorption assembly includes an electromagnetic block 32 with magnetic characteristics and a pressing strip 33. The pressing strip 33 is arranged along the length edge of the photovoltaic module 42 and cooperates with the electromagnetic block 32 arranged below the hard skin 31 to form a plurality of parallel magnetic fields penetrating the thickness of the photovoltaic module 42. The pressing strip 33 is placed above the photovoltaic module 42 and directly above the adhesive layer 43. The electromagnetic block 32 is a long strip structure, which is arranged in the same row along the length direction of the photovoltaic module 42, that is, the electromagnetic block 32 is arranged along the length direction of the hard skin 31 at intervals and is arranged below the hard skin 31 and close to the edge of the wing rib 41. The electromagnetic block 32 and the hard skin 31 are arranged in the cavity between the adjacent wing ribs 41, and all the electromagnetic blocks 32 are arranged below the corresponding pressing strip 33 on the same side.

[0066] As shown in Figure 7As shown, the electromagnetic blocks 32 can be connected in parallel or in series, and when energized, can form a magnetic field together with the upper pressure strip 33, which can penetrate the thickness of the hard skin 31 and the photovoltaic module 42; at the same time, the pressure strip 33 is a flexible and energizable structure, which, when energized, has a vertical downward heat pressure on the photovoltaic module 42 to accelerate the bonding strength of the photovoltaic module 42 with the adhesive layer 43.

[0067] Preferably, all electromagnetic blocks 32 have the same structure and shape, and the electromagnetic blocks 32 do not directly contact the wing rib 41, which can increase the magnetic field coverage area of the electromagnetic blocks 32. In this case, it is required that the magnetic field of each electromagnetic block 32 can cover a width that is 3 times wider than the width of the wing rib 41, so as to completely cover the width position of the pressure strip 33 and prevent the photovoltaic module 42 from being placed deviated on the upper surface of the wing. If the electromagnetic blocks 32 directly contact the wing rib 41, the width of the magnetic field that can be covered by the electromagnetic blocks 32 can only be less than or equal to the width of the wing rib 41, which is not conducive to the laying connection of the photovoltaic module 42 and the wing rib 41.

[0068] After the switch for controlling the electromagnetic blocks 32 is started, the current flowing through the electromagnetic blocks 32 is adjusted to achieve the strength adjustment of the parallel magnetic field formed by the electromagnetic blocks 32 and the pressure strip 33 perpendicular to the thickness of the hard skin 31 and the photovoltaic module 42, and the strength of the parallel magnetic field is set in the range of 0.1-3T.

[0069] The pressure strip 33 is placed above the photovoltaic module 42, the internal material of the pressure strip 33 is a magnetic medium, and the external wrapping material of the pressure strip 33 is a high-insulation elastic material, which can be attracted by the electromagnetic blocks 32 and has good adhesion with the wing rib 41 of the wing of the solar-powered unmanned aerial vehicle 40. When the pressure strip 33 is energized, the heating power of the pressure strip 33 can be adjusted by adjusting the current flowing through the pressure strip 33, and the temperature of the pressure strip 33 is controlled in the range of 30-160℃. Preferably, the width of the pressure strip 33 is 20-40mm and greater than the width of the electromagnetic blocks 32, and the width of the pressure strip 33 is adapted to the width of the wing rib 41 of the wing of the solar-powered unmanned aerial vehicle 40.

[0070] The electromagnetic field generated by the electromagnetic blocks 32 closely adheres to the pressure strip 33 with flexible heat pressing characteristics, which realizes the rapid positioning and bonding laying of the photovoltaic module 42, so as to accurately lay the photovoltaic module 42 on the upper surface of the wing, ensures the stability and consistency of the photovoltaic module 42 and the wing, improves the laying quality, and does not require personnel to participate, which is high in laying efficiency and safe and reliable.

[0071] A laying method of a solar-powered unmanned aerial vehicle flexible photovoltaic module laying device, which comprises the laying device as described above, and the steps comprise:

[0072] The position of the support part 20 is first adjusted to clamp the wing rib 41, so that the wing is horizontally fixed on the support part 20, specifically: the vertical height of the support frame 33 and the horizontal width between adjacent support frames 33 are automatically adjusted to make the wing rib 41 clamped in the clamping groove 24, and the flexible wing in the solar unmanned aerial vehicle 40 is supported and fixed.

[0073] The hard skin card 31 is fixed on the inner side wall between adjacent wing ribs 41 where the photovoltaic module 42 is to be placed, that is, the hard skin 31 is fixed and installed between adjacent wing ribs 41 to provide a matching profile support for the photovoltaic module 42. Among them, the hard skin 31 is lower than the upper surface of the wing rib 41, and the height difference with the upper surface of the wing rib 41 is less than 1mm. The hard skin 31 is made of fluoroplastic material, which has good release effect with the glue 43, and the thickness is 3-5mm. A plurality of round holes are arranged on the hard skin 31, and the diameter of the round holes is 10-15mm.

[0074] Among them, the photovoltaic module 42 is designed to be fully flexible, and the single cell is made of one of flexible gallium arsenide, crystalline silicon and perovskite; the curvature radius of the photovoltaic module 42 is not greater than 500mm, and the performance attenuation after bending 1000 times is not greater than 5%. The glue layer 43 is a thin film glue, and the thickness is 50-200μm.

[0075] The adhesive area on the upper surface of the adjacent wing rib 41 where the photovoltaic module 42 is to be placed is coated with a glue layer 43, that is, the glue layer 43 is coated on the upper surface of the wing rib 41 where the photovoltaic module 42 is to be fixed, that is, the flexible glue layer 43 is fixed on the upper surface of the wing rib 41 of the wing.

[0076] The photovoltaic module 42 is flatly attached above the hard skin 31 by tensioning machine, and the lead cable on the photovoltaic module 42 is passed through the round hole reserved in the hard skin 31. At the same time, the photovoltaic module 42 is placed on the wing rib 41 and the edge side of the photovoltaic module 42 is aligned with the corresponding glue layer 43.

[0077] The photovoltaic module 42 is clamped by the adsorption assembly and a magnetic field is formed, specifically:

[0078] The pressing strip 33 in the adsorption assembly is placed on the two side edges of the upper end surface of the photovoltaic module 42 close to the glue layer 43, and the outer edge of the pressing strip 33 is flush with the outer edge of the photovoltaic module 42, and the pressing strip 33 covers the position of the glue layer 43. At the same time, the electromagnetic block 32 opposite to the pressing strip 33 is placed on the lower end surface of the hard skin 31, that is, the electromagnetic block 32 is fixed below the hard skin 31 in the cavity between adjacent wing ribs 41.

[0079] Further, all the electromagnetic blocks 32 are arranged uniformly along the length direction of the pressing strip 33, and the electromagnetic blocks 32 are not in direct contact with the wing ribs 41, so that the magnetic field coverage area of the electromagnetic blocks 32 can be improved, and in the present case, the magnetic field of each electromagnetic block 32 can cover a width 3 times greater than the width of the wing ribs 41. If the electromagnetic blocks 32 are in direct contact with the wing ribs 41, the magnetic field coverage width of the electromagnetic blocks 32 can only be less than or equal to the width of the wing ribs 41, which is not conducive to the paving connection of the photovoltaic assembly 42 and the wing ribs 41. Preferably, the width of the pressing strip 33 is 20-40 mm and greater than the width of the electromagnetic blocks 32, and the width of the pressing strip 33 matches the width of the wing ribs 41.

[0080] The control is performed on all the electromagnetic blocks 32 to be connected in series or in parallel, and all the pressing strips 33 to be connected in series, so that the electromagnetic blocks 32 and the pressing strips 33 form a plurality of parallel magnetic fields that can penetrate the thickness of the photovoltaic assembly 42.

[0081] The magnetic field intensity is controlled to bond and fix the photovoltaic assembly 42 and the wing ribs 41, and specifically:

[0082] The switch for controlling the electromagnetic blocks 32 is started to form a preliminary pre-tightening pressure, so that the photovoltaic assembly 42 is preliminarily attached to the wing ribs 41 of the aircraft wing, and then the position of the photovoltaic assembly 42 is finely adjusted to ensure that the circuit part of the flexible photovoltaic assembly 42 has no interference with the aircraft wing of the solar-powered unmanned aerial vehicle 40 and has a good shaping effect. Then, the current flowing through the electromagnetic blocks 32 is adjusted to realize the adjustment of the magnetic field intensity, wherein the magnetic field intensity ranges from 0.1 T to 3 T; that is, the electromagnetic field intensity flowing through the electromagnetic blocks 32 is gradually increased, and at the same time, the heating power of the pressing strip 33 is gradually increased, and the heating temperature is increased to 140℃, and the temperature is maintained at 140℃ for 30-60 min, so that the flexible photovoltaic assembly 42 is firmly fixed to the wing ribs 41 of the aircraft wing. Further, the electromagnetic field generated by the electromagnetic blocks 32 is closely attached to the pressing strip 33, so that the photovoltaic assembly 42 is quickly positioned.

[0083] Then, the heating switch of the pressing strip 33 is turned off, and after the temperature is reduced to room temperature or 40℃, the magnetic field intensity is gradually reduced until the pressing strip 33 returns to the natural state, and then the pressing strip 33 is removed.

[0084] The solar-powered unmanned aerial vehicle flexible photovoltaic assembly paving device designed in the present application has a simple structure and is easy to control, and discards the traditional liquid structural adhesive coating scheme. The rapid paving of the super-large size flexible photovoltaic assembly on the solar-powered unmanned aerial vehicle is realized through the heat pressing mode with adjustable adsorption force, which can greatly improve the development efficiency of the solar-powered unmanned aerial vehicle photovoltaic assembly and the consistency of product quality. The present application also proposes a paving method for the solar-powered unmanned aerial vehicle flexible photovoltaic assembly paving device.

[0085] The above detailed description of the application has been given to understand the application better. It should not be taken as limiting the scope of the application. Any changes and improvements that anyone skilled in the art can make within the scope of the application should be deemed to fall within the scope of the patent protection of the application.
