[0038] Embodiment 1:

[0039] like Figure 1 As shown, an anti-interference device for a composite wing UAV of the utility model comprises a UAV 1, wherein the UAV 1 comprises a body 101, a mounting seat 106 is arranged on the top of the body 101, an external thread 107 is arranged on the outer side of the mounting seat 106, and a first thread groove 108 is provided inside the mounting seat 106; the mounting seat 106 is detachably connected with a mounting mechanism 2, the mounting mechanism 2 comprises a device body 201, a mounting rod 202 is arranged on the bottom of the device body 201, a threaded rod 203 is arranged on the bottom of the mounting rod 202, and the threaded rod 203 is meshed with the first thread groove 108; a sliding ring 204 is slidably connected to the outer side of the mounting rod 202, a second thread groove 205 is provided on the inner side of the sliding ring 204, the second thread groove 205 is meshed with the external thread 107, and the thread directions of the external thread 107 and the second thread groove 205 are opposite, and the arrangement of the mounting seat 106 makes the installation and disassembly of the device simple and convenient, and at the same time ensures the stability of the connection through the threaded connection. The external thread 107 and the first thread groove 108 on the mounting seat 106 cooperate with the threaded rod 203 of the mounting mechanism 2 to ensure a tight and stable connection.

[0040] like Figure 2 As shown, a sealing ring is provided at the bottom of the sliding ring 204, and a sealing groove 109 is opened on the outer side of the mounting seat 106, and the sealing groove 109 abuts against the sealing ring. The sealing ring tightly abuts against the sealing groove 109 on the outer side of the mounting seat 106, thereby enhancing the sealing property of the mounting seat 106, effectively preventing external impurities such as dust and moisture from entering, and protecting the integrity and safe operation of the internal structure of the mounting seat 106.

[0041] like Figure 3 As shown, the sealing groove 109 and the sealing ring are used to seal the mounting seat 106. The tight fit between the sealing groove 109 and the sealing ring further ensures the sealing of the mounting seat 106, provides good protection for the internal components, extends the service life of the device, and enhances the working stability of the UAV in various environments.

[0042] like Figure 3As shown, a protective mechanism 3 is arranged on the top of the device body 201, and the protective mechanism 3 includes a rotating seat 301 arranged at the top rear end of the device body 201, the inner side of the rotating seat 301 is rotatably connected to a rotating rod 302, and one side of the rotating rod 302 is rotatably connected to a blocking piece 303. The protective mechanism 3 can be flexibly rotated and adjusted through structures such as the rotating seat 301, the rotating rod 302 and the blocking piece 303, thereby effectively protecting the top of the device body 201 from impact by external objects, thereby enhancing the durability and working reliability of the device.

[0043] like Figure 3 As shown, a sliding seat 304 is provided at the top front end of the device body 201, and a sliding block 305 is slidably connected inside the sliding seat 304. The arrangement of the sliding seat 304 and the sliding block 305 makes the adjustment of the protection mechanism 3 more flexible and precise, and facilitates the adjustment of the protection angle and position as needed, thereby improving the protection effect and stability of the device body 201.

[0044] like Figure 3 As shown, the other end of the baffle 303 is connected to the sliding block 305, and the front end of the sliding block 305 is rotatably connected to the adjusting bolt 306. The baffle 303 is connected to the sliding seat 304 through the sliding block 305 and the adjusting bolt 306, so that the adjustment of the protective mechanism 3 becomes simpler and more convenient. The adjusting bolt 306 can accurately adjust the position of the baffle 303 to meet different protection requirements.

[0045] like Figure 3 As shown, the adjusting bolt 306 passes through the sliding seat 304 and is threadedly connected to the sliding seat 304. The adjusting bolt 306 passes through the sliding seat 304 and is threadedly connected to the sliding seat 304.

[0046] like Figure 3 As shown, the protective mechanism 3 is used to protect the top of the device body 201. The main function of the protective mechanism 3 is to protect the top of the device body 201 from external damage, such as impact, wind and rain, etc., so as to ensure the overall performance and safety of the device.

[0047] like Figure 4 As shown, a support rod 102 is provided at the bottom of the body 101, and a pulley 103 is provided on the outer side of the support rod 102. The support rod 102 and the pulley 103 make it more convenient for the UAV to move on the ground, improve the ground maneuverability and transportation efficiency of the UAV, and also facilitate the storage and management of the UAV.

[0048] like Figure 2As shown, composite wings 104 are provided on both sides of the fuselage 101, and a propeller 105 is provided at the rear end of the fuselage 101. The composite wings 104 provide the UAV with good flight stability and lift, and the propeller 105 provides the UAV with forward power. These settings ensure the stability and power requirements of the UAV in various flight environments, so that the anti-interference device can work stably in various situations.

[0049] During implementation, first, it is necessary to check the drone 1 and all its components, including the fuselage 101, the composite wing 104, the propeller 105, etc., to ensure that they are all in good condition. Then, it is necessary to align the threaded rod 203 of the mounting mechanism 2 with the first thread groove 108 of the mounting seat 106.

[0050] Then, slide the sliding ring 204 downward along the mounting rod 202 until the second thread groove 205 on the inner side thereof is engaged with the outer thread 107 of the mounting seat 106. Since the thread directions of the outer thread 107 and the second thread groove 205 are opposite, when the sliding ring 204 rotates, it moves upward or downward along the mounting rod 202, thereby adjusting the tightness of the mounting mechanism 2.

[0051] Afterwards, adjust the position of the sliding ring 204 until the mounting mechanism 2 is firmly fixed on the mounting seat 106. At this time, the sealing ring should fit tightly in the sealing groove 109 to form a good sealing effect.

[0052] In addition, the protective mechanism 3 on the top of the device body 201 can be adjusted. By rotating the adjusting bolt 306, the position of the sliding block 305 in the sliding seat 304 can be changed, thereby adjusting the angle and position of the baffle 303. The baffle 303 can be rotated on the rotating seat 301 through the rotating rod 302 to adapt to different protection requirements.

[0053] The advantages of this technical solution in practical applications include but are not limited to the following:

[0054] 1. Stable installation and easy operation: The utility model is firmly installed on the top of the UAV body through a specially arranged mounting seat, providing a solid installation foundation for the anti-interference device. At the same time, the tight fit between the external thread and the first thread groove enables the installation mechanism to be firmly and easily connected to the UAV, ensuring the stability of the flight.

[0055] 2. Flexible and adaptable: The installation mechanism ensures the safe fixation of the anti-interference device through the firm connection between the installation rod and the threaded rod and the mounting seat. In particular, the combination of the sliding ring and the second threaded groove provides a flexible fixing method, which enables the device to adapt to the installation of anti-interference equipment of various sizes and weights, greatly enhancing its practicality and adaptability.

[0056] 3. Efficient sealing system: By pairing the sealing ring with the sealing groove, an efficient sealing system is formed. This setting effectively prevents external impurities such as moisture and dust from invading the interior of the mount, provides good protection for the anti-interference device and important components inside the drone, and significantly improves the durability and reliability of the overall equipment.

[0057] 4. Comprehensive protection capability: The adopted protection mechanism can fully protect the top of the device body from external impact through the coordinated action of components such as the rotating seat, rotating rod, baffle, sliding seat, sliding block and adjusting bolt. At the same time, the protection mechanism is also highly flexible and adjustable, and can be precisely adjusted according to different protection needs and environments, greatly improving the safety and service life of the device in various complex environments.
