DETAILED DESCRIPTION

[0051] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0052] Example:

[0053] like Figures 1 to 8 As shown, a photovoltaic panel transportation device based on a drone includes a load-bearing fixture 2, a first rope 3, a second rope 4, a third rope 5 and an unloading structure 9, wherein the load-bearing fixture 2 is connected to the first rope 3, the third rope 5 is respectively connected to the first rope 3 and the second rope 4, the unloading structure 9 is respectively connected to the first rope 3 and the second rope 4 through a fourth rope 6, and the unloading structure 9 is connected to the drone 1 through a fifth rope 7.

[0054] The unloading structure 9 includes a draw line, a line clamp, a fixing frame 905, a first support member 910 and a second support member 911. The draw line passes through the line clamp and the fixing frame 905 and is connected to the fourth rope 6. The line clamp and the fifth rope 7 are respectively connected to the fixing frame 905. The first support member 910 and the second support member 911 are respectively welded to the inner wall of the fixing frame 905. The fifth rope 7 is connected to the drone 1 through the first connecting member 8.

[0055] The draw line includes a first draw line 901 and a second draw line 902, and the line clip includes a first line clip 903 and a second line clip 904. The first line clip 903 and the second line clip 904 are respectively arranged on both sides of the fixing frame 905. The first draw line 901 passes through the first line clip 903 for connection. The first draw line 901 is tied at one end away from the second draw line 902 to prevent it from slipping out of the first line clip 903. The second draw line 902 is also operated in the same way. The second draw line 902 passes through the second line clip 904 for connection. One end of the first line clip 903 is connected to the second draw line 902 and the fourth rope 6. The first line clip 903 and the second line clip 904 can fix the length of the draw line in the direction of being lowered to the second connecting member 906. The first line clip 903 and the second line clip 904 are draw line buckle structures, with springs arranged inside and a sliding structure. The draw line can pass through from the middle. The sliding structure on one side of the line clip is pushed by the spring elastic force to press the draw line and fix it. Pressing the sliding structure can release the fixation of the draw line. This structure is a mature existing technology.

[0056] The second connecting piece 906, the third connecting piece 907, the fourth connecting piece 908 and the fifth connecting piece 909 are welded and connected to the fixing frame 905, the fourth rope 6 is connected to the fixing frame 905 through the second connecting piece 906, the fifth rope 7 is connected to the fixing frame 905 through the third connecting piece 907, the drawing line passes through the fixing frame 905 through the fourth connecting piece 908 and the fifth connecting piece 909, one end of the first supporting piece 910 is connected to the second connecting piece 906, and the other end of the first supporting piece 910 is connected to the third connecting piece 907, and they are in an inverted V shape, and four second supporting pieces 911 are provided, which are respectively connected to the second connecting piece 906, the third connecting piece 907, the fourth connecting piece 908 and the fifth connecting piece 909. The second connecting piece 906, the third connecting piece 907, the fourth connecting piece 908, the fifth connecting piece 909, the first supporting piece 910, and the second supporting piece 911 can be made of waste steel bar residues with a diameter between 6-10 mm.

[0057] The fourth rope 6 is connected to the first rope 3 and the second rope 4 via the sixth connecting member 10, the sixth connecting member 10 is connected to the first rope 3 via the first buckle structure 14, and the sixth connecting member 10 is connected to the second rope 4 via the second buckle structure 15. All the above connecting members may be annular.

[0058] A sleeve rod structure 16, a sliding rod 17, a first elastic member 19 and a second elastic member 20 are arranged on the inner wall of the first buckle ring structure 14, an opening and closing end 21 is arranged on the load-bearing clamp 2, one end of the sliding rod 17 is connected to the inner wall of the first buckle ring structure 14, the other end of the sliding rod 17 extends into the sleeve rod structure 16 for sliding connection, one end of the sleeve rod structure 16 is connected to the inner wall of the first buckle ring structure 14, two ends of the first elastic member 19 are respectively connected to the inner wall of the first buckle ring structure 14, the second elastic member 20 is arranged in the sleeve rod structure 16, one end of the second elastic member 20 is connected to the sliding rod 17, and the other end of the second elastic member 20 is connected to the inner wall of the sleeve rod structure 16, the second buckle ring structure 15 has the same structure as the first buckle ring structure 14, one end of the first buckle ring structure 14 is connected to the first rope 3, the other end of the first buckle ring structure 14 is connected to the sixth connecting member 10, one end of the second buckle ring structure 15 is connected to the second rope 4, and the other end of the second buckle ring structure 15 is connected to the sixth connecting member 10. The slide bar 17 can be made of waste steel bars at the construction site, and the sleeve rod structure 16 can be made of hollow steel pipes or box-shaped steel, but its size must be compatible with the size of the slide bar 17 so that the slide bar 17 can work normally.

[0059] The two first buckle ring structures 14 are connected to both sides of the sixth connecting member 10 respectively, and the second buckle ring structure 15 is connected to the lower part of the sixth connecting member 10 to avoid interference between the first rope 3 and the second rope 4. When the opening and closing end 21 of the first buckle ring structure 14 is pressed, a gap appears in the first buckle ring structure 14, which can be buckled into the sixth connecting member 10 for connection. Under the elastic force of the first elastic member 19 and the second elastic member 20, the gap does not exist, so the first buckle ring structure 14 can be prevented from escaping from the sixth connecting member 10. The operation of the second buckle ring structure 15 is the same as that of the first buckle ring structure 14. The first rope 3 is connected to the first buckle ring structure 14 through the second knotting point 18, and the second rope 4 is connected to the second buckle ring structure 15 through the second knotting point 18. The first elastic member 19 and the second elastic member 20 mainly play the function of telescopic reset, and are not used as the load-bearing structure of the photovoltaic panel. Their specifications and models can be selected according to actual conditions.

[0060] The third rope 5 is arranged around the first rope 3 and the second rope 4, and a first knotting point is arranged at the connection between the third rope 5 and the first rope 3 and the second rope 4, that is, the intersecting ropes are knotted and connected at this point. The unloading structure 9 is a quick-release structure, which can quickly disassemble the part that fixes the photovoltaic panel 12 in combination with the first buckle structure 14 and the second buckle structure 15. When the first buckle structure 14 and the second buckle structure 15 are operated to relax the first draw line 901 and the second draw line 902, the fourth rope 6 no longer tightens the sixth connecting member 10. Since the entire transportation device mainly fixes the photovoltaic panel 12 by tightening the rope, when the sixth connecting member 10 is no longer tightened, the other first ropes 3 and the second ropes 4 are in a relaxed state. At this time, the first buckle structure 14 and the second buckle structure 15 can be opened to quickly take out the photovoltaic panel 12, so that the drone 1 can continue to work without landing.

[0061] The load-bearing clamp 2 includes a cushion block 22 and a rope channel 13. The rope channels 13 are arranged on both sides of the cushion block 22. The cushion block 22 is arranged in an L shape. The rope channel 13 is arranged along the edge of the cushion block 22 following the curve. The first rope 3 passes through the rope channel 13 for sliding connection. Two first ropes 3 can be arranged.

[0063] T1. According to the size of a single photovoltaic panel 12 and the weight of a single transport, calculate the maximum weight that the drone can carry, the rope tension, and the diameter value, and prepare the transport device;

[0064] T2. After passing the first rope 3 through the four load-bearing clamps 2, first buckle structures 14 are respectively installed at both ends of the first rope 3, and then the first buckle structure 14 is connected to the sixth connecting member 10;

[0065] T3, after the second rope 4 and the bottom of the first rope 3 are knotted and fixed, the second buckle structure 15 is installed at both ends of the second rope 4 respectively, and then the second buckle structure 15 is connected to the sixth connecting member 10;

[0066] T4, fix the third rope 5 to the outside of the middle of the first rope 3 and the second rope 4, so that the first rope 3, the second rope 4 and the third rope 5 are connected to obtain a photovoltaic panel fixing device;

[0067] T5, fix the unloading structure 9 to the drone through the fifth rope 7, and tighten the fifth rope 7;

[0068] T6, connect the fourth rope 6 to the sixth connector 10, fix the photovoltaic panel fixing device to the unloading structure 9 through the fourth rope 6, and tighten the first wire clip 903 and the second wire clip 904, so that the first draw wire 901 and the second draw wire 902 pull the fourth rope 6 upward;

[0069] T7, start the opening and closing ends 21 of the first buckle ring structure 14 and the second buckle ring structure 15, load the required number of photovoltaic panels 12 for transportation, and place the photovoltaic panels with their long sides facing downwards;

[0070] T8, close the opening and closing ends 21 of the first buckle structure 14 and the second buckle structure 15, and calibrate the stability of the load-bearing clamp 2 and the tightness of the rope;

[0071] T9. Start UAV 1 to transport photovoltaic panels. UAV 1 must slowly rise and land;

[0072] T10. Rapid installation and removal of the photovoltaic panel 12 is achieved by controlling the tightness of the first line card 903 and the second line card 904.

[0073] Assuming that the length×width×height of the photovoltaic panel 12=L×B×H, N photovoltaic panels 12 are transported each time, K is the distance between the axes of the rope channels 13 on both sides of the cushion block 22, and then:

[0074] The dimensions of the photovoltaic panel fixing device must meet the following requirements:

[0075] K=NH (1)

[0076] T=L (2)

[0077] E=B (3)

[0078] In formula (1) to formula (3): K is the distance between the axis centers of the rope channels 13 on both sides of the cushion block 22; T is the bottom width of the photovoltaic panel fixing device; E is the side height of the photovoltaic panel fixing device; N is the number of photovoltaic panels 12; L is the length of the photovoltaic panel 12; B is the width of the photovoltaic panel 12; and H is the height of the photovoltaic panel 12.

[0079] The calculation method of the tension of the fifth rope 7 includes:

[0080] F a =NW a +W b +F c (4)

[0081] The calculation method of the tension of the fourth rope 6 includes:

[0082]

[0083] N is the number of photovoltaic panels, W a is the weight of a single photovoltaic panel, W b F is the net weight of the photovoltaic panel fixing device, c To unload the deadweight of the structure 9 , θ is the angle formed by the two fourth ropes 6 at the second connecting member 906 .

[0084] In order to facilitate on-site installation and ensure safe transportation, select ropes with greater single rope force:

[0085] The formula for calculating the maximum weight that the drone can carry is:

[0086] P=F=max{F a ,F b} (6)

[0087]

[0088] After transforming formula (6) and formula (7), the rope diameter formula can be obtained as follows:

[0089]

[0090] F is the rope tension value, which includes the rope tension values ​​of the fourth rope 6 and the fifth rope 7. a is the tension of the fifth rope 7, F b is the tension of the fourth rope 6, we know: F c <F b ≤F a , P is the maximum weight that drone 1 can carry, σ max is the maximum tensile stress of the rope, which is the rope nameplate value; D is the rope diameter, in mm, and then we get:

[0091] P=F=max{F a ,F b} (9)

[0092]

[0093] The diameters of the fourth rope 6 and the fifth rope 7 can be calculated by formula (10). In order to ensure that the ropes can be freely inserted into the rope hole 13, the diameter of the reserved rope hole 13 should not be less than D. The model of the drone can be determined based on the maximum weight P value that the drone can carry.
