Description

Technical Field

[0001] The utility model relates to a mounting mechanism, in particular to a wingtip mounting mechanism for a geophysical prospecting unmanned aerial vehicle. Background Art

[0002] UAVs are unmanned aircraft that are controlled by radio remote control equipment or onboard computer program control systems. UAVs have a simple structure and low operating costs. They can not only complete the tasks performed by manned aircraft, but are also suitable for tasks that manned aircraft are not suitable for. They play a great role in emergency response and early warning of emergencies. Compared with manned aircraft, UAV geophysical exploration has the advantages of low cost, high safety, and low complexity. It has been a widely used geophysical exploration method in recent years.

[0003] For example, the Chinese patent publication number CN214138956U discloses a wingtip mounting device for an aeromagnetic geophysical exploration UAV with an adjustable attitude, which includes a vertical section on the outside of the main wing, a probe cover, a forward probe rod, and a magnetic probe; the wingtip of the main wing section of the UAV is equipped with the vertical section on the outside of the main wing, magnetic probes are installed at both ends of the vertical section on the outside of the main wing, and the probe cover is installed outside the magnetic probe; the forward probe rod is perpendicular to the vertical section on the outside of the main wing, that is, parallel to the heading direction of the UAV, and the magnetic probe is installed inside the forward probe rod. When the UAV is conducting geomagnetic field detection, the appearance of this solution can effectively reduce the additional resistance of the UAV caused by the probe arrangement and provide a positive gain to the lift-to-drag ratio of the entire aircraft, which can well ensure the smooth operation of the UAV aeromagnetic measurement operation process; at the same time, a total of 6 probes on both sides of the UAV can adjust different attitudes according to needs to meet the test requirements, improve the data accuracy of the geomagnetic measurement results, and provide high-quality geomagnetic measurement results;

[0004] Some problems were found during the use of the above-mentioned existing adjustable attitude aeromagnetic geophysical exploration UAV wingtip mounting device. First, although the mounting device can effectively carry multiple probes, UAV geophysical exploration often requires the use of multiple devices to continuously carry out exploration operations, and it is impossible to quickly replace other probes for other exploration or tasks, resulting in the problem of a high-value UAV having a relatively wide range of uses. Utility Model Content

[0005] The purpose of the utility model is to provide a wingtip mounting mechanism for a geophysical exploration UAV to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wingtip mounting mechanism for a geophysical prospecting UAV, comprising a wingtip, a bracket fixedly connected under the wingtip, a connecting shaft fixedly connected behind the bracket, a connecting frame provided under the wingtip, a probe clamped under the connecting frame, a bearing sleeve embedded and installed in the connecting frame near one end edge, the bearing sleeve is rotatably connected to the connecting shaft, a fixing hole is provided in the connecting frame, a threaded connection hole is provided at the end of the wingtip, and a threaded rod is threadedly installed in the threaded connection hole.

[0007] Preferably, a limit block is transversely fixed to the underside of the wing tip, and the rear side of the limit block is aligned with the rear side of the bracket.

[0008] Preferably, a dovetail slot is provided on the front of the connecting frame, a dovetail slider is fixedly connected to the probe, and the dovetail slider is slidably matched with the dovetail slot.

[0009] Preferably, a plurality of threaded fixing holes are provided on the bottom of the connecting frame, and the connecting frame is L-shaped as a whole and fits the end of the wing tip.

[0010] Preferably, an interference head is fixedly connected to one end of the threaded rod, and an inner corner hole is opened at the other end of the interference head.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Use an internal angle wrench to insert into the internal angle hole to drive the threaded rod to rotate, so that the interference head is retracted into the threaded connection hole. At this time, the connection frame restriction will be released, so that the connection frame can be moved back and removed. After the dovetail slider is no longer blocked by the limit block, the probe can be easily moved forward and removed for replacement.

[0013] 2. The connecting frame can be rotatably connected to the connecting shaft through the bearing sleeve, and can be installed under the wingtip. At the same time, the other end of the connecting shaft is not connected to any other structure. The connecting frame can be slid out from the rear of the connecting shaft, so that the connecting frame can be easily removed. When there is no need to mount equipment, the end fixing mechanism can be completely removed to avoid affecting normal flight. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a wingtip mounting mechanism for a geophysical prospecting UAV, comprising a wingtip 1, a bracket 2 fixedly connected to the bottom of the wingtip 1, a connecting shaft 201 fixedly connected to the back of the bracket 2, a connecting frame 3 provided under the wingtip 1, a probe 4 clamped under the connecting frame 3, a bearing sleeve 301 embedded and installed in the connecting frame 3 near one end edge, the bearing sleeve 301 is rotatably connected to the connecting shaft 201, a fixing hole 302 is provided in the connecting frame 3, a threaded connection hole 101 is provided at the end of the wingtip 1, and a threaded rod 5 is threadedly installed in the threaded connection hole 101.

[0022] In this embodiment, the connecting frame 3 can be rotatably installed under the wingtip 1 by rotating the bearing sleeve 301 and the connecting shaft 201. At the same time, the other end of the connecting shaft 201 is not connected to any other structure, and the connecting frame 3 can slide out from the rear of the connecting shaft 201. The threaded rod 5 cooperates with the fixing hole 302 to limit the rotation and forward and backward movement of the connecting frame 3, so that the threaded rod 5 and the connecting shaft 201 are used to fix the connecting frame 3 to the end of the wingtip 1, and the probe 4 is clamped under the connecting frame 3 so that the probe 4 is mounted on the end of the wingtip 1. The threaded rod 5 is rotated to screw it into the threaded connection hole 101, and the threaded rod 5 is removed from the fixing hole 302 to release the restriction on the connecting frame 3. At this time, the connecting frame 3 can be easily removed, which is convenient for replacing different probes 4 later.

[0023] Among them, in order to achieve the purpose of fixing the probe 4 under the connecting frame 3, the present device adopts the following technical solution: a limit block 102 is laterally fixed under the wingtip 1, the rear of the limit block 102 is aligned with the rear of the bracket 2, a dovetail groove 303 is provided on the front of the connecting frame 3, and a dovetail slider 401 is fixed on the probe 4, and the dovetail slider 401 slides in cooperation with the dovetail groove 303.

[0024] The probe 4 is clamped under the connecting frame 3 by sliding the dovetail slider 401 in cooperation with the dovetail slot 303. Since the dovetail slot 303 is opened from the front of the connecting frame 3, when the dovetail slider 401 is clamped into the dovetail slot 303, the limit block 102 will block the dovetail slider 401 from moving out of the dovetail slot 303, thereby fixing the probe 4 under the connecting frame 3.

[0025] Among them, in order to achieve the purpose of rotating the threaded rod 5, this device adopts the following technical solution: a number of threaded fixing holes 304 are opened under the connecting frame 3, the connecting frame 3 is L-shaped as a whole, fitting the end of the wingtip 1, and an interference head 501 is fixed to one end of the threaded rod 5, and an inner corner hole 502 is opened at the other end of the interference head 501.

[0026] Different geophysical exploration equipment can be connected by bolts through the threaded fixing hole 304. The connecting frame 3 is L-shaped as a whole and fits onto the end of the wingtip 1, so that the interference head 501 can be inserted into the fixing hole 302. The outer wall of the interference head 501 is smoothed to reduce the friction between the interference head 501 and the inner wall of the fixing hole 302, making it easier for the interference head 501 to be removed or inserted into the fixing hole 302. An internal angle wrench is inserted into the internal angle hole 502, so that the threaded rod 5 can be easily rotated to drive the interference head 501 to retract into the threaded connection hole 101.

[0027] The working principle and usage process of the present invention are as follows: by connecting the shaft rod 201 and the interference head 501 to cooperate with each other, the connecting frame 3 can be fixed under the end of the wingtip 1. At this time, the end of the dovetail slot 303 will be blocked by the limit block 102, so that the dovetail slider 401 can be blocked in the dovetail slot 303, thereby effectively fixing the probe 4 under the connecting frame 3. When a different probe 4 needs to be replaced, use an internal angle wrench to insert the internal angle hole 502 to drive the threaded rod 5 to rotate, so that the interference head 501 is retracted into the threaded connection hole 101. At this time, the restriction of the connecting frame 3 will be released, so that the connecting frame 3 can be moved backward and removed. After the dovetail slider 401 is no longer blocked by the limit block 102, it can be moved forward and removed for replacement.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
