Description

Technical Field

[0001] The utility model belongs to the technical field of UAV launching equipment, and particularly relates to an orientation adjusting device for a UAV launching rack. Background Technique

[0002] UAVs have been widely used in modern society. Since UAVs do not require a pilot, they can perform many dangerous tasks. Civilians, the application prospects of UAVs in the fields of aerial photography, forest fire prevention inspection, geological survey, high-voltage transmission line inspection, oil field pipeline inspection, highway management, emergency rescue and ambulance are also extremely broad. Militarily, UAVs, with their accurate, efficient and flexible reconnaissance, interference, deception, search and rescue, calibration and combat capabilities under non-standard conditions, have significantly improved the efficiency and effectiveness of military operations.

[0003] At present, many small UAVs are launched by rocket boost on the launching rack. Under the thrust of the booster rocket engine, the UAV can quickly fly away from the launching rack. After takeoff, the booster rocket is discarded, and the main engine on the aircraft completes the flight mission. When using rocket boost zero-length launch, the ambient wind has an important impact on the launch takeoff quality and safety of the UAV. Generally speaking, it is preferred to launch the UAV against the wind, followed by launching with the wind. Side wind launch should be avoided as much as possible, especially head-on side wind. This is because side wind will have an adverse impact on the stability and flight trajectory of the UAV, increasing the risk during the launch process.

[0004] The existing devices for adjusting the launch direction basically drive the launch rack to rotate through a hydraulic system, with a high cost; moreover, a lot of anchor bolts need to be drilled on the ground, the workload is very large, and only limited direction adjustment can be achieved. Therefore, there is an urgent need to provide a UAV launching rack that can conveniently and quickly adjust the direction. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies in the prior art and provide an orientation adjusting device for a UAV launching rack.

[0006] The specific technical solution adopted by the utility model is as follows:

[0007] The utility model provides an orientation adjusting device for a UAV launching rack, including a base and a launching rack; a plurality of base fixing plates for fixing with the ground are fixed under the base, and fixing holes are opened on each base fixing plate; fixing pieces pass through the fixing holes on the base fixing plates to fix the base on the ground;

[0008] An arc-shaped adjustment groove is provided on the base; a launch rack fixing plate is fixed to the bottom surface of each vertical rod of the launch rack; the launch rack fixing plate is located on the adjustment groove of the base and can rotate along the direction in which the adjustment groove is provided to achieve 360° stepless orientation adjustment; a connection hole is provided on the launch rack fixing plate, and a connecting member passes through the connection hole on the launch rack fixing plate and the adjustment groove on the base to fix the launch rack on the base.

[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the present utility model can be combined correspondingly without conflict.

[0024] As Figure 1 shown, as a preference of the specific implementation manner provided by the present utility model, this embodiment provides an orientation adjustment device for a drone launch rack, mainly including a base 1 and a launch rack 2.

[0025] In the device provided by the present utility model, a plurality of base fixing plates 102 for fixing to the ground are fixed below the base 1, and fixing holes are formed in each base fixing plate 102; a fixing member passes through the fixing holes in the base fixing plate 102 to fix the base 1 to the ground. In order to firmly fix the base 1 to the ground and reduce the vibration and displacement caused by the impact on the base 1 during the drone launch process, anchor bolts are used as the fixing members in this embodiment. Anchor bolts can not only effectively prevent the device from tipping over or shifting, but also be applicable to various different ground materials.

[0026] In this embodiment, both the base 1 and the base fixing plates 102 are made of steel plates. Six base fixing plates 102 are provided and evenly distributed along the circumferential direction of the base 1. The base fixing plates 102 are fixed below the base 1 by welding. Since the base fixing plates 102 have a certain thickness, the base 1 is also at a certain distance from the ground, which is convenient for subsequent installation of the connecting members for fixedly connecting the launch rack 2 and the base 1. It should be noted that the base 1 and the base fixing plates 102 can also be made of other materials, as long as the base can stably support the upper launch rack.

[0027] As Figure 2 shown, an arc-shaped adjustment groove 101 is formed in the base 1. The base 1 can be made of a circular steel plate or an arc-shaped steel plate. In this embodiment, the adjustment groove 101 is provided with six arc-shaped segments each with an angle of 60°. Of course, those skilled in the art can also directly set the adjustment groove 101 to three arc-shaped segments each with an angle of 120°, or set it to two arc-shaped segments each with an angle of 180° according to actual needs.

[0028] In the device provided by the present utility model, a launcher fixing plate 201 is fixed to the bottom surface of each vertical rod of the launcher 2. In this embodiment, the launcher has four vertical rods, so four launcher fixing plates 201 are provided. The launcher fixing plate 201 is located on the adjustment groove 101 of the base 1 and can rotate along the opening direction of the adjustment groove 101 to achieve 360° stepless orientation adjustment. A connection hole is formed on the launcher fixing plate 201, and a connecting member passes through the connection hole on the launcher fixing plate 201 and the adjustment groove 101 on the base 1 to fix the launcher 2 to the base 1. In this embodiment, the connecting member can directly adopt a bolt.

[0029] When using the orientation adjustment device of the above-mentioned drone launcher, first fix the base to the ground with anchor bolts, and then fix the launcher to the adjustment groove of the base through bolts according to the on-site wind direction. If the environmental wind direction at the launch site changes, only need to loosen the bolts, adjust the launcher to the appropriate direction, and then fix the bolts. Through this device, the rapid adjustment of the drone launch direction can be realized, and the problem that the change of the wind direction at the drone launch site affects the launch safety is solved.

[0030] The above-described embodiments are only a preferred solution of the present utility model, but it is not intended to limit the present utility model. Those of ordinary skill in the relevant technical field can still make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
