[0002] Global climate change and population growth pose severe challenges to sustainable agricultural development. As the core resource for food production, the dynamic monitoring of arable land is crucial to ensuring food security. Remote sensing technology, with its advantages of wide coverage, high timeliness, and low cost, has become the core means of monitoring arable land changes. With the advancement of agricultural modernization, the application of drone technology in the agricultural field is becoming increasingly widespread, especially in arable land distribution monitoring and livestock management, where it has shown significant advantages. In terms of arable land distribution monitoring, drones, equipped with high-definition digital cameras, multispectral sensors, and other equipment, can acquire real-time spatial information of farmland, including field boundaries, crop type identification, and area estimation, significantly improving the efficiency and accuracy of farmland information monitoring.

[0003] However, existing remote sensing drones, when equipped with high-definition digital cameras and other equipment, are usually directly exposed to the elements. During the process of collecting images of farmland distribution, they are easily affected by harsh environments, which can cause camera equipment to malfunction. At the same time, in harsh environments, impurities can easily adhere to the camera lens and fog up, causing the lens to be obstructed. This brings a lot of trouble to the image collection of farmland distribution and reduces the effectiveness of use. Utility Model Content

[0004] The purpose of this invention is to provide a remote sensing drone for image acquisition, in order to solve the problems in the prior art where, in harsh environments, the camera lens is easily obstructed by impurities and fog, causing considerable trouble for image acquisition of farmland distribution and reducing the effectiveness of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a remote sensing drone for image acquisition, comprising:

[0006] The drone component and the protective component mounted on the bottom of the drone component, and the cleaning component mounted on the front end of the protective component;

[0007] The drone component includes a drone body, and a gimbal frame is mounted on the bottom of the drone body.

[0008] The protective assembly includes a protective box installed between the pan-tilt units, a mounting bracket slidably installed inside the protective box, a remote sensing camera fixedly installed on the top of the mounting bracket, and a protective lens corresponding to the lens of the remote sensing camera embedded in the front end of the protective box.

[0009] The cleaning assembly includes a threaded rod and a sliding rod respectively installed at the front end of the protective box.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1:

[0028] This utility model provides a remote sensing drone for image acquisition, comprising:

[0029] The drone component 1, the protective component 2 mounted on the bottom of the drone component 1, and the cleaning component 3 mounted on the front end of the protective component 2;

[0030] The drone component 1 includes a drone body 11, and a gimbal frame 15 is mounted on the bottom of the drone body 11.

[0031] The protective component 2 includes a protective box 21 installed between the pan-tilt frame 15. A mounting bracket 25 is slidably installed inside the protective box 21. A remote sensing camera 22 is fixedly installed on the top of the mounting bracket 25. A protective lens 26 corresponding to the lens of the remote sensing camera 22 is embedded in the front end of the protective box 21.

[0032] The cleaning component 3 includes a threaded rod 33 and a slide rod 38 respectively installed at the front end of the protective box 21. A moving tube 32 is installed between the threaded rod 33 and the slide rod 38. The rear end of the moving tube 32 is connected to a number of jet nozzles 34 arranged at equal intervals. The jet nozzles 34 correspond to the protective lens 26. A heating wire 311 is fixedly installed inside the moving tube 32.

[0033] As can be seen from the above, by installing the gimbal 15 on the underside of the drone body 11 during use, and by mounting the remote sensing camera 22 on the mounting bracket 25 and inserting the mounting bracket 25 into the protective box 21, the remote sensing camera 22 can be easily placed inside the protective box 21, so that the lens of the remote sensing camera 22 can correspond to the protective lens 26, allowing the remote sensing camera 22 to perform normal shooting operations. After the drone body 11 takes off, it can easily collect images of farmland distribution from high altitude. Through the angle rotation function of the gimbal 15, the angle of the protective box 21 can be controlled, so that the remote sensing camera 22 can easily adjust the shooting angle synchronously with the protective box 21. The protective box 21 and the protective lens 26 can easily protect the body and lens of the remote sensing camera 22, and can avoid damage to the remote sensing camera 22 caused by the harsh environment.

[0034] During image acquisition, the rotation of the threaded rod 33 drives the moving tube 32 to move up and down, which in turn drives the jet head 34 to move up and down. By introducing airflow into the moving tube 32, the jet head 34 can blow off the impurities adhering to the protective lens 26. The air outlet angle of the jet head 34 is tilted downward, allowing the airflow to be blown obliquely onto the protective lens 26, which can push the impurities downward and blow them off the protective lens 26 relatively quickly. The heating wire 311 can heat the air inside the moving tube 32, and the hot airflow blown out can heat the protective lens 26, which can prevent the protective lens 26 from fogging in harsh weather such as humid and cold weather, and can make high-altitude shooting clearer, bringing more convenience to the image acquisition of farmland distribution.

[0035] From the appendix Figure 2It can be seen that the bottom of the drone body 11 is fixedly installed to the gimbal frame 15 through the mounting base 14, and the two sides of the drone body 11 are fixedly installed with support frames 12, and the bottom of the support frame 12 is fixedly installed with a support plate 13.

[0036] As can be seen from the above, the mounting base 14 can conveniently provide an installation position for the gimbal frame 15, which can be fixed at the bottom of the drone body 11. The support frame 12 and the support plate 13 can conveniently provide support for the drone body 11 during landing, which can prevent the protective box 21 from contacting the ground.

[0037] For details, please refer to the appendix. Figure 3 As shown, a sealing cover 23 is fixedly installed at the rear end of the mounting bracket 25. The sealing cover 23 is attached to the rear end of the protective box 21, and the sealing cover 23 and the protective box 21 are fixed together by a fixing bolt 24.

[0038] As can be seen from the above, by sliding the mounting bracket 25 into the protective box 21, the sealing cover 23 can be fitted with the protective box 21, which can easily seal the opening at the rear end of the protective box 21. By rotating the fixing bolt 24, the sealing cover 23 and the protective box 21 can be easily fixed together.

[0039] For details, please refer to the appendix. Figure 4 As shown, a protective cover 31 is fixedly installed at the front end of the protective box 21, and the movable tube 32 extends into the interior of the protective cover 31.

[0040] As can be seen from the above, after cleaning the protective lens 26, the moving tube 32 and the jet head 34 can be moved into the protective cover 31 for concealment. The protective cover 31 can protect the moving tube 32 and the jet head 34 from damage caused by collisions with external objects.

[0041] Working principle: After takeoff, the UAV body 11 carries the remote sensing camera 22 to a high altitude. The angle adjustment function of the gimbal 15 adjusts the protective box 21 to a suitable angle, allowing the remote sensing camera 22 to adjust synchronously with the protective box 21. The protective lens 26 allows light to enter the protective box 21, enabling the remote sensing camera 22 to collect images of the farmland distribution. The protective lens 26 and the protective box 21 protect the lens and body of the remote sensing camera 22 from damage during shooting. The rotation of the threaded rod 33 drives the moving tube 32 to move up and down. The jet nozzle 34 blows off the impurities adhering to the protective lens 26. At the same time, the hot air jet heats the protective lens 26, preventing fogging and allowing for clearer image capture.

[0042] Example 2:

[0043] Reference Appendix Figure 4 As shown, the movable tube 32 and the threaded rod 33 are connected by a threaded sleeve 37, and the movable tube 32 and the slide rod 38 are slidably installed by a sliding sleeve 39.

[0044] As can be seen from the above, the threaded sleeve 37 and the threaded rod 33 are connected by a threaded engagement, which allows the threaded rod 33 to rotate forward and backward, thereby driving the threaded sleeve 37 to move up and down. This drives the moving tube 32 to move up and down, allowing the jet head 34 to easily blow airflow back and forth onto the surface of the protective lens 26, which can quickly blow off impurities from the surface of the protective lens 26. The sliding sleeve 39 can slide up and down along the sliding rod 38. By using the limiting effect of the sliding rod 38 on the sliding sleeve 39, the rotation of the threaded rod 33 can drive the moving tube 32 to move up and down.

[0045] Reference Appendix Figure 4 As shown, the threaded rod 33 and the protective box 21 are rotatably mounted together via a shaft bracket 36, and a driving component 35 corresponding to the threaded rod 33 is fixedly mounted on the top of the shaft bracket 36.

[0046] As can be seen from the above, the threaded rod 33 can be supported by the shaft bracket 36, enabling the threaded rod 33 to rotate. The drive component 35 is an electric motor, which can provide power to the threaded rod 33, making it easy to drive the threaded rod 33 to rotate.

[0047] Reference Appendix Figure 5 As shown, a miniature air pump 310 is fixedly installed on the top of the moving tube 32, and the miniature air pump 310 is connected to the moving tube 32.

[0048] As can be seen from the above, the micro air pump 310 can easily inject air into the moving tube 32, and the airflow can be distributed along the moving tube 32 to multiple jet heads 34. The airflow can be blown out through the jet heads 34 to blow off the impurities adhering to the surface of the protective lens 26.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
