Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a water landing gear with an anti-slip structure for an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle specifically refers to an unpiloted aircraft, which is a flying vehicle controlled by a radio remote control device and a self-contained program control device. Simply put, it is an unpiloted flying vehicle. Compared with traditional manned aircraft, it has the advantages of small size, low cost, and convenient use. At present, unmanned aerial vehicles can be divided into many types and are widely used in fields such as aerial photography, surveying and mapping, reconnaissance, and agriculture.

[0003] Due to the different application fields of unmanned aerial vehicles, unmanned aerial vehicles often need to land on the water due to work requirements. When an unmanned aerial vehicle lands on the water, a floating frame often needs to be assembled. However, the existing floating frames of unmanned aerial vehicles have a relatively simple structure, average floating performance, and are relatively inconvenient to disassemble and install. Therefore, a water landing gear with an anti-slip structure for an unmanned aerial vehicle is introduced according to the above-mentioned problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a water landing gear with an anti-slip structure for an unmanned aerial vehicle in view of the above-mentioned deficiencies in the prior art.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a water landing gear with an anti-slip structure for an unmanned aerial vehicle, including a base, and a support mechanism is arranged on the base;

[0006] The support mechanism includes a first support column, an inner support column, an airbag foot, a bolt, a threaded port, a connecting column, a support airbag, and an inflation port;

[0007] The first support column is fixedly installed on one side of the outer wall of the base. The inner support column is slidably connected inside the first support column. The airbag foot is fixedly installed at the bottom of the inner support column. A threaded port is opened on the base. The connecting column is threadedly connected below the threaded port. The support airbag is fixedly installed at the bottom of the connecting column. By arranging multiple groups of first support columns, the stable anti-slip effect on the water is strengthened.

[0008] Preferably, a bolt is threadedly connected to the first support column, and the extending end of the bolt is installed on the inner support column.

[0009] Preferably, an inflation port is opened at the top of the support airbag. The number of the first support columns is four groups, and the four groups of first support columns are respectively symmetrically installed at both ends of the outer wall of the base.

[0010] Preferably, a fixing mechanism is provided on the base. The fixing mechanism includes a bidirectional screw rod which is rotatably connected. The extended end of the bidirectional screw rod is fixedly sleeved with a worm gear.

[0011] Preferably, a support plate is installed on the outer wall of the base. A worm is threadedly connected to the support plate, and the worm meshes with the worm gear.

[0012] Preferably, fixing blocks are threadedly connected to the outer wall of the bidirectional screw rod. The bottom of the fixing block is slidably connected to the inner wall of the base. The number of the fixing blocks is two groups, which are symmetrically arranged at both ends of the outer wall of the bidirectional screw rod respectively.

[0013] Adopting the above technical solution, the utility model can bring the following beneficial effects:

[0014] First, for the water landing gear with an anti-slip structure for an unmanned aerial vehicle, by installing a first support column on one side of the base and slidably connecting an inner support column in the support column, the position of the airbag feet can be adjusted arbitrarily. And a support airbag is threadedly connected under the base, which enhances the stability of the overall unmanned aerial vehicle during landing on the water surface.

[0015] Second, for the water landing gear with an anti-slip structure for an unmanned aerial vehicle, by providing a fixing mechanism on the base, rotating the worm drives the worm gear to rotate. When the worm gear rotates, it drives the bidirectional screw rod to rotate. When the bidirectional screw rod rotates, the fixing blocks on the outer wall of the bidirectional screw rod are fixed to the bottom of the unmanned aerial vehicle, and it can adapt to unmanned aerial vehicles of different sizes, facilitating quick limit fixing.
