[0016] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0017] (1) The present invention uses a square plate, a round shell, a T-shaped shaft, a frame rod, a concave plate, a U-shaped plate, a surveying and mapping module, a gear ring, a vertical rod, a U-shaped wide frame, and a U-shaped shaft frame to match the groove roller.

[0018] (2) The present invention uses the setting of the anti-falling device to make the L-shaped rod, the ring plate and the I-shaped ring cooperate with the double pipe frame.

The L-shaped rod drives the double pipe frame to rotate, and the double pipe frame supports the vertical rod to rotate, so that the vertical rod rotation remains stable, preventing the unstable center of gravity of the frame rod from causing the surveying and mapping module to shake during shooting.

[0019] (3) The present invention sets an anti-falling device so that the L-shaped plate, the short rod and the vertical short plate cooperate with the sponge block. The L-shaped plate drives the short rod to rotate, the short rod drives the vertical short plate to rotate, and the vertical short plate drives the sponge block to rotate. During the rotation, the sponge block wipes the surface of the gear ring to prevent foreign matter from being trapped in the teeth of the gear ring and causing the equipment to run unsmoothly.

[0020] (4) The present invention arranges a light-blocking device so that the U-shaped rod, the T-shaped ring and the slot block cooperate with the light-shielding plate. The U-shaped rod drives the T-shaped ring to rotate, the T-shaped ring drives the slot block to rotate, and the slot block drives the light-shielding plate to rotate. The light-shielding plate blocks the sunlight on the side of the surveying and mapping module, preventing the sunlight from shining on the side of the surveying and mapping module and causing unclear shooting of the surveying and mapping module.

[0021] (5) The present invention sets a light-blocking device so that the square block and the arc-shaped spring piece cooperate with the square cover. The square block drives the arc-shaped spring piece to rotate, and the arc-shaped spring piece drives the square cover to rotate. Under the elastic force of the arc-shaped spring piece, the vibration amplitude of the light shielding plate during rotation is reduced, thereby preventing the light shielding plate from vibrating at high frequencies and causing poor shielding effect.

[0033] Bolt holes 101 are provided on all four sides of the top surface of the square plate 1. The bolt holes 101 are used to fix the bottom of the drone. A flange 102 is provided at the bottom of the outer wall of the vertical rod 9. The outer wall of the flange 102 is welded to the outer wall of the frame rod 4. Several heat dissipation vents 103 are provided on the bottom of the left and right sides of the surveying and mapping module 7.

[0034] The operator installs the square plate 1 under the drone through the bolt hole 101, and the operator controls the drone to fly above the photovoltaic area. When it is necessary to adjust the angle to survey the depression of the photovoltaic area, the square plate 1 supports the round shell 2, and the operator uses the remote control to start the servo motor in the round shell 2.

[0036] Working principle: Install the square plate 1 under the drone through the bolt hole 101, and control the drone to fly above the photovoltaic area. The square plate 1 supports the circular shell 2, and the rotating shaft of the servo motor drives the T-shaped shaft 3 to rotate. The T-shaped shaft 3 rotates in the T-shaped circular groove of the circular shell 2. The T-shaped shaft 3 drives the frame rod 4 to rotate, and the frame rod 4 drives the concave plate 5 to rotate. The concave plate 5 drives the U-shaped plate 6 to rotate, and the U-shaped plate 6 drives the surveying and mapping module 7 to rotate.

The vertical rod 9 drives the U-shaped wide frame 10 to rotate, and the U-shaped wide frame 10 drives the U-shaped axis frame 11 to rotate. The U-shaped axis frame 11 drives the groove roller 12 to rotate. The groove roller 12 contacts the surface of the gear ring 8 during rotation, and the groove of the groove roller 12 is stuck on the gear ring 8 and rolls.

[0037] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the anti-falling device 13 includes an L-shaped rod 131, which passes through and is fixed to the bottom surface of the U-shaped wide frame 10, and the L-shaped rod 131 is located on the left side of the vertical rod 9. The left end of the L-shaped rod 131 is fixed with a ring plate 132, and the bottom of the outer wall of the circular shell 2 is fixed with an I-shaped ring 133.

The double pipe rack 134 is used to support the vertical rod 9. The L-shaped rod 131 is located below the U-shaped axis frame 11, and a circular opening is opened at the bottom of the outer wall of the double pipe rack 134.

[0038] While the vertical rod 9 drives the U-shaped wide frame 10 to rotate, the U-shaped wide frame 10 drives the L-shaped rod 131 to rotate, the L-shaped rod 131 drives the ring plate 132 to rotate, the ring plate 132 rotates in the I-shaped ring 133, and the I-shaped ring 133 supports the rotation of the ring plate 132. At the same time, the L-shaped rod 131 drives the double-tube rack 134 to rotate. During the rotation of the double-tube rack 134, the double-tube rack 134 supports the rotation of the vertical rod 9, so that the rotation of the vertical rod 9 remains stable, thereby avoiding the problem of shooting jitter of the mapping module 7 caused by the unstable center of gravity of the frame rod 4 during the high-altitude mapping of photovoltaic areas by the drone.

[0039] An L-shaped plate 135 is fixed in the middle of the front and back of the ring plate 132. Two short rods 136 are respectively passed through and fixed opposite the L-shaped plate 135. A vertical short plate 137 is fixed opposite the short rod 136. A sponge block 138 is fixed opposite the vertical short plate 137. The opposite side of the sponge block 138 is in sliding contact with the outer wall of the gear ring 8. The sponge block 138 is used to wipe the outer wall of the gear ring 8.

The sponge block 138 wipes the surface of the gear ring 8 during the rotation process to keep the teeth gaps of the gear ring 8 free of foreign matter, thereby avoiding the problem of foreign matter in the teeth gaps of the gear ring 8 causing the equipment to run poorly during the high-altitude mapping of photovoltaic areas by the drone.

[0041] The light blocking device 14 includes a U-shaped rod 141, which is fixed to the inner wall of the circular opening of the double-tube frame 134.

A groove block 143 is fixed to the outer wall of the T-shaped ring 142. A light shielding plate 144 is fixed to the right side of the groove block 143. The light shielding plate 144 is located to the right of the surveying and mapping module 7 and is used to block sunlight on the right side of the surveying and mapping module 7.

[0042] While the L-shaped rod 131 drives the double tube rack 134 to rotate, the double tube rack 134 drives the U-shaped rod 141 to rotate, the U-shaped rod 141 drives the T-shaped ring 142 to rotate, the T-shaped ring 142 drives the slot block 143 to rotate, and the slot block 143 drives the sunshade 144 to rotate. During the rotation process, the sunshade 144 blocks the sunlight on the side of the surveying and mapping module 7, thereby avoiding the problem of unclear shooting of the surveying and mapping module 7 due to sunlight shining on the side of the surveying and mapping module 7 when the drone is surveying the photovoltaic area at high altitude.

A square cover 147 is fixed to the end of the arc-shaped spring piece 146 away from the block 145. The square cover 147 is sleeved on the right end of the frame rod 4. The elastic force of the arc-shaped spring piece 146 is used to reduce the amplitude of the sunshade 144 when it moves.

[0044] While the slot block 143 drives the sunshade 144 to rotate, the sunshade 144 drives the block 145 to rotate, the block 145 drives the arc-shaped spring piece 146 to rotate, and the arc-shaped spring piece 146 drives the square cover 147 to rotate. Under the elastic force of the arc-shaped spring piece 146, the vibration amplitude of the sunshade 144 during rotation is reduced, thereby avoiding the problem of poor shielding effect caused by high-frequency vibration of the sunshade 144 during high-altitude mapping of photovoltaic areas by the drone.
