Description

Waterproof structure of fixed wing tip Technical Field The utility model belongs to the technical field of aircrafts, and particularly relates to a waterproof structure for a fixed wing tip. Background In military exercises and weapon trials, unmanned aerial vehicles are required to simulate airborne targets in various real scenes, including flights in severe weather conditions and in complex geographical environments. For example, in offshore military exercises, unmanned aerial vehicles need to fly and recover in humid and high-salinity marine environments, and waterproof designs can ensure that the unmanned aerial vehicles work normally in such environments, so that reliable targets are provided for testing and training of weapon systems, and tactical technical performance of the weapon systems in complex environments is more accurately checked. If the unmanned aerial vehicle does not have good waterproof design, moisture can lead to the problem such as electronic component short circuit, metal part corruption in the unmanned aerial vehicle inside to reduce unmanned aerial vehicle's performance and reliability, cause equipment to damage even and can't use again, especially wing wingtip department is the mounted position of equipment such as drag pipe, therefore the waterproof important ring of unmanned aerial vehicle of wingtip, design wingtip waterproof construction becomes necessary. Disclosure of utility model The utility model provides a waterproof structure for a fixed wing tip, and aims to solve the problems that in the prior art, the wing tip of an unmanned aerial vehicle cannot be waterproof or the waterproof performance of gluing is poor. Therefore, the utility model provides a waterproof structure for a fixed wing tip, which comprises a binding post and an insulating sealing screw sleeve, wherein the binding post is sleeved in the insulating sealing screw sleeve. Preferably, the device further comprises a fastener, and the fastener is connected with one end of the binding post. Preferably, the terminal further comprises a first sealing element, and the first sealing element is connected to the outer side of the terminal. Preferably, the sealing device further comprises a second sealing element, and the outer side of the insulating sealing screw sleeve is connected with the second sealing element. Preferably, the insulating sealing screw sleeve is a plastic core. Preferably, the inner side and the outer side of the insulating sealing screw sleeve are both provided with threads. Preferably, the fastener is a compression nut. Preferably, the first sealing element and the second sealing element are raw material belts. Preferably, the insulation sealing screw sleeve further comprises a detachable connecting piece, one end of the detachable connecting piece is connected with the other end of the binding post, one end of the detachable connecting piece is sleeved in the insulation sealing screw sleeve, and the other end of the detachable connecting piece is positioned outside the insulation sealing screw sleeve. Preferably, the detachable connection member is a set screw. The utility model has the beneficial effects that: 1. The waterproof structure of the fixed wing tip prevents moisture from entering electronic elements, circuits and the like in the wing tip of the unmanned aerial vehicle, and avoids equipment faults caused by problems such as short circuit and corrosion, so that the flight safety of the unmanned aerial vehicle under various weather conditions is ensured, the risk of flight accidents is reduced, and the flight safety is enhanced. 2. The waterproof structure for the fixed wing tip effectively protects the wing tip and internal components of the unmanned aerial vehicle from being corroded by water, reduces component damage and performance reduction caused by damp, prolongs the service life of the wing tip of the unmanned aerial vehicle and the whole aircraft, and reduces the use cost and maintenance frequency. 3. The waterproof structure of the fixed wing tip can keep the aerodynamic shape and structural integrity of the wing tip of the unmanned aerial vehicle, avoid wing tip deformation, weight change and the like caused by moisture accumulation or component damage, ensure stable aerodynamic performance such as lift force, resistance and the like of the unmanned aerial vehicle in the flight process, and improve the flight precision and controllability. 4. The waterproof structure for the fixed wing tip enables the unmanned aerial vehicle to fly normally under severe weather conditions such as humidity, raininess and the like, is not limited by environmental humidity and precipitation, expands application scenes and task ranges of the unmanned aerial vehicle, such as tasks of monitoring, reconnaissance and the like in environments such as ocean, rainforest and the like, and improves reliability and stability of the whole unmanned aerial vehicle system.
