Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle inspection, in particular to a take-off and landing platform of a boiler inspection unmanned aerial vehicle. Background Art

[0002] In order to reduce and prevent the occurrence of boiler water wall pipe explosion and leakage accidents, it is necessary to regularly use drone inspection systems to inspect water wall tubes. When drones inspect boiler water wall tubes, they need to enter through a boiler observation window of a specific size, but the boiler entrance and exit are narrow. In order to ensure the load capacity and stable flight of the drone, a landing platform that is convenient for drones to take off and land at high altitudes and suitable for installation at the boiler high-altitude window is needed.

[0003] In actual use, bolts are usually used to install and fix the landing platform, which makes installation and disassembly inconvenient and is not conducive to the subsequent maintenance of the landing platform. In addition, it is difficult to adjust the angle of the platform body by fixing with bolts, thereby making it difficult to ensure that the platform body is fixed parallel to the ground. Therefore, the staff needs to spend a lot of time adjusting the level of the platform body. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a landing platform for a boiler inspection drone, which is used to check whether the water-cooled wall tubes of the boiler have cracks or wear, so as to facilitate timely repair or replacement of the water-cooled wall tubes. The boiler has a boiler observation window 1, and the boiler observation window 1 has an opening 101. The drone is placed through the opening 101 or the internal situation of the boiler is observed. A platform body 16 is arranged at the opening 101. The platform body is a flat plate with a thickness. One end of the platform body 16 extends into the boiler, and the other end is connected to a fixed structure. The fixed structure is fixedly arranged on the outward surface of the boiler observation window 1, and the connection between the platform body 16 and the boiler observation window 1 is achieved through the fixed structure. Preferably, the fixing structure includes a mounting plate 5 for connecting the platform body 16, the mounting plate 5 is a rectangular plate, having a first surface 501 and a second surface 502 opposite to the first surface 501, the first surface 501 faces outward, away from the inside of the boiler; the mounting plate 5 is installed on the outward surface of the boiler observation window 1 across the opening 101, and the second surface 502 faces the inside of the boiler; a support frame 13 is provided on the second surface 502 of the mounting plate 5, and the platform body 16 is connected to the support frame 13; preferably, the support frame 13 is a rectangular frame, consisting of an upper frame, a lower frame opposite to the upper frame, a left frame and a right frame, the size of which matches the opening 101, and is embedded in the opening 101 to achieve position fixation of the platform body 16.

[0024] In order to realize the quick installation of the platform body 16 and the boiler observation window 1, a limit block 2 is arranged on the outer side surface of the boiler observation window 1, and there are two limit blocks 2, which are symmetrically arranged on both sides of the opening 101; the mounting plate 5 has a limit groove 6 corresponding to the position of the limit block 2, and the limit groove 6 is engaged with the limit block 2 to realize the installation of the mounting plate 5 and the boiler observation window 1.

[0025] Furthermore, the mounting plate 5 has a receiving cavity 7, which is rectangular, and both ends in the length direction penetrate the side end faces of the corresponding mounting plates 5 to form a through cavity. A first connecting plate 11 is slidably connected in the receiving cavity 7. The first connecting plate 11 consists of two pieces, which are respectively arranged on both sides of the length direction of the receiving cavity 7. There is a gap between the two first connecting plates 11. The opposite side end faces of the two first connecting plates 11 are connected with racks 12. The length of the racks 12 is less than the gap length. The two racks 12 are arranged in parallel and are respectively located above and below the receiving cavity 7. A gear 10 meshing with the two racks 12 is arranged between the two racks 12. A rotating shaft 8 is fixedly connected at the center of the gear 10. One end of the rotating shaft 8 penetrates the first surface 501 of the mounting plate 5 and is connected to the handle 9; a portion for fixing the first The fixed through slots 3 at the ends of the connecting plate 11 are opposite to each other; during the installation process, the gear 10 is driven to rotate clockwise by rotating the handle 9, and then the first connecting plate 11 is driven to move relative to each other by the rack 12 matched with the gear 10, so that the spacing between the two first connecting plates 11 is reduced until the two first connecting plates 11 are located between the two limiting through slots 6, so as to prevent the ends of the first connecting plates 11 from blocking the limiting through slots 6 and blocking the engagement of the limiting block 2 with the limiting through slots 6; after the limiting block 2 and the limiting through slots 6 are engaged, the gear 10 is driven to rotate counterclockwise by rotating the handle 9, and then the first connecting plates 11 are driven to move opposite to each other by the rack 12 matched with the gear 10, until the ends of the first connecting plates 11 are embedded in or penetrate the fixed through slots 3, and the installation of the mounting plate 5 is completed. The multi-directional positioning of the mounting plate 5 and the boiler observation window 1 is realized, so that the connection between the two is more firm. Preferably, in order to better ensure that the first connecting plate 11 retracts between the two limiting grooves 6, the sum of the length of the rack 12 and twice the length of the first connecting plate 11 connected thereto is equal to the spacing between the two limiting grooves 6. In the process of the rack 12 driving the first connecting plate 11 to slide, when the free end of the rack 12 contacts the end face of the first connecting plate 11 on the other side, the gear 10 can no longer rotate, and the two first connecting plates 11 are also exactly located between the two limiting grooves 6 without blocking the limiting grooves 6.

[0026] Furthermore, if Figure 4As shown, the platform body 16 is rotatably connected to the left and right frames of the support frame 13 through the connecting shaft 15. The platform body 16 can rotate around the connecting shaft 15. A threaded rod 14 is threadedly connected to the lower frame of the support frame 13 below. The top of the threaded rod 14 is hinged to the bottom surface of the platform body 16 through a hinge plate. A handwheel 141 is connected to the end of the threaded rod 14. The lifting and lowering of the threaded rod 14 is controlled by rotating the handwheel 141, thereby driving the platform body 16 to rotate around the connecting shaft 15, thereby realizing the angle adjustment of the platform body 16 relative to the horizontal plane, reducing the difficulty of the staff in adjusting the horizontality of the platform body 16.
