[0060] See also Figure 1-5 The utility model provides a technical solution: an unmanned aerial vehicle inspection auxiliary device, comprising:

[0061] The drone compartment 3 has a drone charging seat fixedly mounted on the bottom of its inner cavity. The drone compartment 3 has a built-in rechargeable power supply for supplying power to the drone charging seat, and the drone charging seat is used to supply power to the drone 5 plugged therein, and at the same time, the placement position of the drone 5 is positioned to avoid displacement during the hoisting process;

[0062] The drone 5 is located in the drone compartment 3 and is plugged into a drone charging station for charging;

[0063] A transverse sliding connection structure 4 is provided in the middle of the upper surface of the drone cabin 3;

[0064] A steel cable winding mechanism 2, which is located above the drone cabin 3;

[0065] The wire rope reeling mechanism 2 includes a wire rope 25 reeled therein, and the lower end of the wire rope 25 is fixedly connected to the movable part of the transverse sliding connection structure 4;

[0066] The steel cable winding mechanism 2 drives the drone warehouse 3 to rise and fall by winding the steel cable 25. As the steel cable 25 is wound or lowered, it drives the fixed connection block 43 connected to it to slide in the horizontal slide groove 41. There are two steel cables 25 on the left and right. When winding, the steel cable 25 drives the connection block 43 to move to the outer end of the horizontal slide groove 41, and winds until the top surface of the drone warehouse 3 fits with the bottom surface of the steel cable winding mechanism 2. The driving motor 23 used is a power-off self-locking motor, which self-locks after power failure to ensure the stable hoisting of the drone warehouse 3.

[0067] The rear end of the cable winding mechanism 2 is fixedly mounted with a fixed bracket 1, and the rear end of the fixed bracket 1 is fixedly mounted on the top of the transmission tower;

[0069] In some embodiments, in order to land the drone 5 on the power line when necessary, the power line is used to support the drone 5, and the drone 5 only needs part of the propeller to provide power for forward and backward movement, and also includes a power line guide structure 7, which is installed on the bottom surface of the drone 5;

[0070] The transmission line guide structure 7 comprises:

[0071] There are two vertical plates 71 parallel to each other on the left and right sides, and the two vertical plates 71 are symmetrically fixedly assembled on the left and right sides of the bottom surface of the drone 5;

[0072] The left and right sides of the bottom surface of the drone 5 are longitudinally provided with sliding guide grooves 72;

[0073] The sliding guide groove 72 is located at the inner edge of the vertical plate 71;

[0074] The sliding guide groove 72 slides on the transmission line, and the inner wall of the vertical plate 71 slides and fits with the transmission line. Through the shielding of the vertical plates 71 on the left and right sides, the sliding guide groove 72 on the bottom of the drone 5 that falls on the transmission line is sleeved on the transmission line. It is suitable for use on two transmission lines arranged side by side. The spacing between the vertical plates 71 on both sides and the sliding guide grooves 72 on both sides is set according to the spacing between the two transmission lines arranged side by side. Through the above setting, when the drone 5 is inspecting, only part of the propellers need to work, which reduces power consumption and extends the inspection time.

[0075] In some embodiments, in order to ensure that the drone 5 is placed stably, the drone 5 includes:

[0076] The drone body 51 has a bracket 52 fixedly mounted on its bottom surface;

[0077] The transmission line guide structure 7 is assembled on the bottom surface of the bracket 52 .

[0078] In some embodiments, in order for the bracket 52 to ensure the stability of the support, the bracket 52 is U-shaped, and the shape of the bracket 52 is small at the top and large at the bottom.

[0079] In some embodiments, in order to enable the connecting block 43 to slide in the transverse sliding groove 41 in coordination with the winding of the wire rope winding mechanism 2, the transverse sliding connecting structure 4 includes:

[0080] A transverse chute 41 is provided in the middle of the upper surface of the drone cabin 3;

[0081] Wedge-shaped sliders 42 are slidably engaged on both left and right sides of the inner cavity of the transverse slide groove 41;

[0082] A connecting block 43 is fixedly mounted on the upper end of the wedge-shaped slider 42;

[0083] The number of the steel cables 25 wound up in the steel cable winding mechanism 2 is two;

[0084] The lower end of the steel cable 25 is fixedly connected to the connecting block 43 on the same side. There are two steel cables 25, so the lifting and lowering is more stable.

[0085] In some embodiments, in order to drive the drone cabin to be raised and lowered, it is raised to the upper end of the transmission tower for storage after use, and lowered to the lower end of the transmission tower when in use, and the wire rope winding mechanism 2 includes:

[0086] The strip-shaped rectangular housing 21 has strip-shaped mounting grooves 22 on both sides of its bottom surface;

[0087] The left and right ends of the strip-shaped rectangular housing 21 are fixedly connected with a driving motor 23, and the output end of the driving motor 23 passes through the outer wall of the strip-shaped rectangular housing 21. The driving motor 23 used is a power-off self-locking motor, which self-locks after power failure to ensure the stable hoisting of the drone cabin 3;

[0088] The output end of the driving motor 23 is fixedly connected with a round rod 24, and the round rod 24 is located in the strip-shaped mounting groove 22 on the same side;

[0089] One end of the steel cable 25 is wound and fixed on the round rod 24, and the other end of the steel cable 25 passes through the strip mounting groove 22 on the same side. The driving motor 23 drives the round rod 24 to rotate to reel in or lower the steel cable 25 thereon. During the reeling or lowering process, the position of the steel cable 25 wound on the round rod 24 changes, and the lower end of the steel cable 25 drives the connecting block 43 and the wedge-shaped slider 42 to slide in the horizontal slide groove 41.

[0090] In other embodiments, the wire rope winding mechanism 2 may be provided with a corresponding controller and a communication module, and the controller controls the wire rope winding mechanism 2 to be turned on or off through a mobile phone APP, a communication module and a controller.

[0091] In some embodiments, in order to shield the front opening of the drone compartment 3, to protect the drone 5 when it is stored, and to facilitate opening when the drone 5 needs to be taken out, the door panel shielding structure 6 includes:

[0092] A strip-shaped through hole 61 is provided on the front side of the upper surface of the drone cabin 3;

[0093] A door panel 62 is slidably inserted into the strip-shaped through hole 61;

[0094] A door panel opening limit structure 63 is installed at the lower end of the front wall of the door panel 62; the door panel 62 is pulled out from the upper end to open, and after the door panel 62 is raised to a high position, the raised door panel 62 can be limitedly connected to the upper surface of the drone compartment 3 by operating the door panel opening limit structure 63, so as to facilitate the removal and placement of the drone 5.

[0095] In some embodiments, in order to clamp the door panel 62 on the upper surface of the drone compartment 3 after it is raised, so as to facilitate the placement and removal of the drone 5, the door panel opening limit structure 63 includes:

[0096] A strip-shaped groove 631 is longitudinally opened at the lower end of the front wall of the door panel 62;

[0097] A strip plate 632 is hinged at the lower end of the inner cavity of the strip groove 631, and the strip plate 632 is interference fit with the inner wall of the strip groove 631;

[0098] After the strip plate 632 is raised, it is flipped over to be horizontal and against the upper surface of the drone cabin 3. The strip plate 632 is interference fit with the inner wall of the strip groove 631. Sufficient external force needs to be applied during the flipping process. The strip plate 632 flipped to the horizontal is limited by this interference fit. The strip groove 631 is longer than the strip plate 632. After the strip plate 632 is stored in the strip groove 631, there is enough space at the upper end to conveniently buckle out the upper end of the strip plate 632.

[0099] In some embodiments, in order to reduce the impact on the door panel 62 when it is closed, a rubber pad 8 is adhered and fixed to the bottom surface of the door panel 62.

[0100] In some embodiments, in order to fix the drone cabin 3 on the transmission tower, the fixing bracket 1 includes:

[0101] The mounting plate 11 has mounting holes 13 evenly formed thereon, through which bolts for fixing pass, and is fixed to the upper end of the transmission tower by the cooperation of the bolts and nuts;

[0102] Connecting rods 12 are vertically fixedly mounted on both left and right sides of the front wall of the mounting plate 11;

[0103] The front ends of the left and right connecting rods 12 are fixedly connected to the rear ends of the cable winding mechanism 2 .

[0104] Working principle:

[0105] During use, the control cable winding mechanism 2 is opened, the control cable 25 is lowered to drive the connecting block 43 to slide in the horizontal slide groove 41, and the drone warehouse 3 is lowered to the ground as the cable 25 is lowered. The user opens the door panel shielding structure 6 to take out the drone 5 for use, and puts the drone 5 back into the drone warehouse 3 after use, closes the door panel shielding structure 6, and opens the cable winding mechanism 2 again. The control cable 25 is wound up and drives the connecting block 43 to slide in the horizontal slide groove 41. The drone warehouse 3 rises as the cable 2 is wound up until it is in contact with the bottom surface of the cable winding mechanism 2. The driving motor 23 used in the cable winding mechanism 2 is a power-off self-locking motor. After power failure, self-locking ensures that the drone warehouse 3 is hoisted stably, and the stored drone 5 is hoisted to the top of the transmission tower, which is more effective to prevent human damage and theft.
