Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles (UAVs), and in particular is a ground receiving device for a power grid inspection UAV. Background Art

[0002] In recent years, with the improvement of science and technology, relevant research on drone power inspection has been carried out both at home and abroad. Some technical difficulties of drones have been gradually overcome, and drones can carry corresponding equipment to complete designated tasks as needed. Some drones will use ground receiving equipment during use. The drone takes off from the matching ground receiving equipment, completes the operation in the air, gradually descends and finally lands on the ground receiving equipment.

[0003] For example, the utility model with announcement number CN205422102U discloses a ground receiving device for drones, including a landing platform for carrying drones, the landing platform being provided with a sliding guide mechanism for quickly guiding the landing drone onto the landing platform, the sliding guide mechanism comprising a recessed portion provided on the landing platform, the top opening area of the recessed portion being larger than the bottom area, and the sidewall connecting the top opening and the bottom being a smooth slope. When the drone lands, the sliding surface of the drone's support foot contacts and slides with the smooth slope to quickly guide the drone onto the landing platform. This utility model has the advantages of being simple and compact in structure, not only being able to quickly guide the landing drone to the optimal parking position, but also being able to cushion the impact force of the drone during landing, facilitating the storage and transportation of the drone, and being particularly suitable for use with tethered drones.

[0004] When the above-mentioned device lifts the landing platform through the screw assembly, the landing platform will be higher or lower than the sliding door. At this time, when the drone lands, due to the small area of the landing platform, the drone will often land between the lifting platform and the sliding door. At this time, there is a height difference between the landing platform and the sliding door, which will cause the drone to roll over, making it inconvenient for people to receive the landing of the drone. Therefore, a ground receiving device for a power grid inspection drone is proposed to solve the problems raised in the background technology. Summary of the Invention

[0020] The present invention cooperates with the threaded rod, the third gear, the sliding door body and the connecting support rod and other structures, so that the device can prevent the problem of the drone rolling over due to the height difference between the lifting platform body and the sliding door body. By running the power motor, the first gear drives the second gear and the threaded rod to rotate, and then the third gear rotates, so that the third gear drives the sliding door body and the top end of the connecting support rod to the outside side. At this time, the connecting block drives the bottom end of the connecting support rod to move upward, and the connecting support rod will support the side of the bottom of the sliding door body away from each other.

After the connecting block contacts the top of the inner cavity of the protective shell, the lifting platform continues to drive the oblique block to move in the upward direction. At this time, the oblique block will squeeze the piston column and cause the piston column to move to the side away from the oblique block. At this time, the gas inside the first cavity is compressed and transported to the inside of the second cavity through the connecting pipe, thereby pushing the piston plate to drive the T-shaped rod to rotate. At the same time, the gas inside the second cavity away from the connecting pipe is discharged through the pressure-equalizing pipe. At this time, the vertical groove inside the card hole will be misaligned with the protrusion, thereby fixing the connecting block, thereby preventing the first elastic spring from resonating and causing the connecting block and the connecting support rod to drive the sliding door body to vibrate.

At this time, the connecting block 9 drives the bottom end of the connecting support rod 13 to move upward. The connecting support rod 13 will support the side of the bottom of the sliding door body 16 that is away from each other. At the same time, the rotation of the threaded rod 4 will also cause the lifting platform 6 and the oblique long block 10 to move upward synchronously. When the two sides of the top of the lifting platform 6 contact the top of the inner cavity of the protective shell 1, the lifting platform 6 and the sliding door body 16 are maintained at the same height. At the same time, the two sides of the lifting platform 6 will also contact the inner ends of the sliding door bodies 16 on both sides, so that the lifting platform 6 and the sliding door body 16 are maintained at the same height, so as to facilitate the landing of the drone.

[0035] like Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9As shown, the fixed structure 18 includes a piston column 181, and a first cavity 182, a second cavity 184, a pressure equalizing pipe 1811 and a connecting pipe 1812 are respectively provided inside the front and rear ends of the two side walls of the protective shell 1, the piston column 181 is movably connected to the inside of the first cavity 182, and the side of the piston column 181 away from the first gear 3 is fixedly connected to the second elastic spring 183, and the front and rear ends of the inner cavities on both sides of the protective shell 1 are movably connected with T-shaped rods 185, and the middle part of the outer surface and the rear end of the top of the outer surface of the T-shaped rod 185 are respectively fixedly connected to the first annular spring sheet 186 and the piston plate 188, a vertical groove 187 is provided at the bottom of the T-shaped rod 185, and a card hole 189 is provided at the top of the connecting block 9, and a protrusion 1810 is fixedly connected to the middle upper part of one side of the inner cavity of the card hole 189, and the vertical groove 187 cooperates with the protrusion 1810, and one end of the bottom of the outer surface of the T-shaped rod 185 is fixed with the card hole 189. Internal movable connection; after the connecting block 9 contacts the top of the inner cavity of the protective shell 1, the lifting platform 6 continues to drive the oblique block 10 to move upward. At this time, the oblique block 10 will squeeze the piston column 181 and make the piston column 181 move to the side away from the oblique block 10. At this time, the gas inside the first cavity 182 is compressed and transported to the inside of the second cavity 184 through the connecting pipe 1812, thereby pushing the piston plate 188 to drive the T-shaped rod 185 to rotate. At the same time, the gas inside the second cavity 184 away from the connecting pipe 1812 is discharged through the pressure equalizing pipe 1811. At this time, the vertical groove 187 inside the card hole 189 will be misaligned with the protrusion 1810, thereby fixing the connecting block 9, thereby preventing the first elastic spring 12 from resonating and causing the connecting block 9 and the connecting support rod 13 to drive the sliding door body 16 to vibrate.

[0036] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 As shown, the protective structure 19 includes a reel 191, which is movably connected to the front and rear ends on both sides of the inner cavity of the protective shell 1, and the inner cavity of the reel 191 is fixedly connected to a second annular spring piece 192, and the second annular spring piece 192 is fixedly connected to the protective shell 1 on the side away from the reel 191, and the outer surface of the reel 191 is fixedly connected to a protective cloth 193, which is movably connected to the inside of the protective shell 1, and one end of the bottom of the protective cloth 193 is fixedly connected to the side of the connecting block 9 away from the top of the card hole 189; the lifting platform 6 will drive the oblique long block 10 to move downward, and at the same time, the oblique long block 10 presses the connecting block 9 and drives the connecting block 9 to move downward, and at this time, it will also drive one end of the bottom of the protective shell 1 to move downward, and at the same time, the reel 191 rotates to compress the second annular spring piece 192, thereby completing the sealing of the protective shell 1, thereby protecting the drone inside the protective shell 1.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, the first gear 3 is meshed with the second gear 5, the lifting platform 6 is movably connected to the inner cavity of the protective shell 1, the inner cavity in the middle of both sides of the lifting platform 6 is threadedly connected to the middle of the outer surface of the threaded rod 4, the number of sliding door bodies 16 is two, and one end of the bottom of the two sliding door bodies 16 is in contact with the top of the protective shell 1, the sliding door body 16, the middle of the outer surface of the limiting rod 17 is movably connected to the inner cavity at the top of the protective shell 1, one end of the top of the threaded rod 4 passes through the top of the protective shell 1 and the threaded rod 4 extends to the interior of the sliding door body 16, the third gear 7 is meshed with the tooth plate 8, the top of the connecting block 9 close to the end of the oblique long block 10 is matched with the bottom of the oblique long block 10, the top end of the connecting support rod 13 is hinged to the inner cavity at the bottom of the matching block 14, the bent spring sheet 15 is fixedly connected to the inner cavity of the sliding door body 16 at one end away from the matching block 14, and the limiting column 1 The top and bottom of 1 are fixedly connected to the top and bottom of the inner cavity of the protective shell 1 respectively, and the top and bottom of the first elastic spring 12 are fixedly connected to the connecting block 9 and the protective shell 1 respectively; through the cooperation between the third gear 7 and the tooth plate 8, the sliding door body 16 will move. When the sliding door body 16 moves toward the outside, the lifting platform 6 drives the inclined long block 10 to rise, thereby releasing the restriction on the connecting block 9, and then due to the elastic force of the first elastic spring 12, the connecting block 9 rises. When the top of the connecting block 9 contacts the top of the inner cavity of the protective shell 1, the lifting platform 6 continues to rise with the rotation of the threaded rod 4. At this time, the outward movement of the sliding door body 16 will cause the matching block 14 to move toward the side close to the bent spring sheet 15, thereby maintaining support for the end of the bottom of the sliding door body 16 away from the protective shell 1.

[0038] like Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9As shown, the side of the first cavity 182 away from the piston column 181 is connected to one end of the top of the connecting pipe 1812, and the bottom end of the connecting pipe 1812 is connected to the side of the top of the second cavity 184 away from the piston column 181. The end of the second elastic spring 183 away from the piston column 181 is fixedly connected to the protective shell 1, the side of the oblique long block 10 close to the piston column 181 cooperates with the piston column 181, and the piston plate 188 is movably connected to the inside of the second cavity 184. The inner cavity of the second cavity 184 away from the side of the connecting pipe 1812 is connected through the pressure equalizing pipe. The channel 1811 is in communication with the outside world, and the end of the first annular spring piece 186 away from the T-shaped rod 185 is fixedly connected to the protective housing 1; the design of the connecting pipe 1812 plays a role in exhausting the gas inside the second cavity 184 away from the side of the connecting pipe 1812, thereby facilitating the injection of gas into the second cavity 184 from the connecting pipe 1812, making it easier for the piston plate 188 to rotate. The design of the first annular spring piece 186 and the piston column 181 ensures the subsequent reset of the T-shaped rod 185 and the piston column 181;

[0039] It is worth noting here that when the top of the lifting platform 6 is at the same height as the top of the sliding door body 16 , the side of the oblique block 10 close to the piston column 181 will contact and squeeze the piston column 181 .

[0040] The working principle and use process of the present invention:

[0041] When the drone needs to land, running the power motor 2 will cause the first gear 3 to drive the second gear 5 and the threaded rod 4 to rotate, thereby causing the third gear 7 to rotate. At this time, through the cooperation between the third gear 7 and the tooth plate 8, and due to the limiting effect of the limit rod 17, the third gear 7 will drive the sliding door body 16 and the top end of the connecting support rod 13 to move to the outside side. At the same time, due to the elastic force of the first elastic spring 12, the connecting block 9 will drive the bottom end of the connecting support rod 13 to move upward. At this time, the connecting support rod 13 will support the side of the bottom of the sliding door body 16 that is away from each other. At the same time, the rotation of the threaded rod 4 will also cause the lifting platform 6 and the oblique long block 10 to move upward synchronously. When the two sides of the top of the lifting platform 6 contact the top of the inner cavity of the protective shell 1, the lifting platform 6 and the sliding door body 16 remain at the same height. At the same time, the two sides of the lifting platform 6 will also contact the inner end of the sliding door body 16 on both sides to complete the operation;

[0042] When the connecting block 9 contacts the top of the inner cavity of the protective shell 1, the interior of the card hole 189 will cooperate with one end of the bottom of the T-shaped rod 185, and the lifting platform 6 continues to drive the oblique long block 10 to move upward. At this time, the oblique long block 10 will squeeze the piston column 181 and make the piston column 181 move to the side away from the oblique long block 10. At this time, the gas inside the first cavity 182 is compressed and transported to the inside of the second cavity 184 through the connecting pipe 1812, thereby pushing the piston plate 188 to drive the T-shaped rod 185 to rotate, the first annular spring sheet 186 will be compressed, and the gas inside the second cavity 184 away from the connecting pipe 1812 is discharged through the pressure equalizing pipe 1811. At this time, the vertical groove 187 inside the card hole 189 will be misaligned with the protrusion 1810, thereby fixing the connecting block 9, thereby preventing the first elastic spring 12 from resonating and causing the connecting block 9 and the connecting support rod 13 to drive the sliding door body 16 to vibrate;

[0043] When the device needs to reset the drone, the lifting platform 6 will drive the oblique block 10 to move downward, and at the same time, the oblique block 10 will press the connecting block 9 and drive the connecting block 9 to move downward. At this time, it will also drive one end of the bottom of the protective shell 1 to move downward, and at the same time, the reel 191 will rotate so that the second annular spring sheet 192 is compressed, thereby completing the sealing of the protective shell 1.
