Technical Field

[0001] This utility model relates to the field of surveying drones, and more specifically, to a protective structure for surveying drones. Background Technology

[0002] In the field of surveying and mapping, drones are increasingly widely used. However, their rotors are extremely susceptible to collisions with external objects during flight, such as tree branches, birds, or debris in complex environments. This can not only damage the rotors and affect the drone's flight performance, but may even cause the drone to crash, resulting in equipment loss and interruption of surveying and mapping tasks.

[0003] How to invent a protective structure for surveying drones to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a protective structure for a surveying drone, aiming to improve the problem that when a drone is used for surveying work, the drone rotor is easily hit by external objects during flight. This may not only damage the rotor and affect the flight performance of the drone, but may even cause the drone to crash, resulting in equipment loss and interruption of the surveying mission.

[0005] This utility model is implemented as follows: A protective structure for a surveying drone includes a protective net covering the outside of the rotors on both sides of the surveying drone. The protective net includes a pair of opposing upper and lower covers, which are detachably connected by fasteners. Both ends of the upper and lower covers are arc-shaped structures coaxially arranged with the corresponding rotors of the surveying drone, and a protective isolation structure is provided in the hollow part of the arc structure. The two rotors on one side of the surveying drone are located in the internal space formed by the upper and lower covers. Two parallel connecting rods are integrally provided on the outer wall of one side of the upper cover, and a connecting slider is integrally provided at the end of each connecting rod. Each connecting rod is detachably connected to a connecting mechanism provided on the outer wall of the corresponding side of the surveying drone through the connecting slider.

[0006] In a preferred embodiment of this utility model, both the upper cover and the lower cover include a connecting frame and a structural frame. Each structural frame is located on one side of the corresponding connecting frame and the two are arranged in parallel. The area of ​​the structural frame is smaller than that of the connecting frame. The two ends of the connecting frame and the structural frame form corresponding arc-shaped structures. Each connecting frame has a plurality of evenly distributed connecting holes for inserting fasteners on its circumferential surface.

[0007] In a preferred embodiment of this utility model, a plurality of protective rods are integrally provided between the outer walls of the corresponding arc structure at one end of the connecting frame and the corresponding structural frame. These rods are evenly distributed in a ring.

[0008] In a preferred embodiment of this utility model, the structural frame is an overall closed rod-shaped structure in the middle connected to an annular structure at both ends.

[0009] In a preferred embodiment of this utility model, the connecting frame, the structural frame, and the protective rod are all made of low-weight, high-strength materials.

[0010] In a preferred embodiment of this utility model, the connecting mechanism includes two connecting blocks. Each connecting block is detachably connected to the outer wall of the corresponding side of the surveying drone by fasteners. A connecting groove corresponding to the connecting slider is opened on one side surface of each connecting block. Each connecting slider is slidably connected in the corresponding connecting groove. An abutment limiting block is also slidably connected in each connecting groove. The two abutment limiting blocks are connected to the locking mechanism.

[0011] In a preferred embodiment of this utility model, the locking mechanism includes a connecting plate, with both ends of the connecting plate fixedly connected to two abutting limit blocks respectively. An insertion hole is provided on the upper surface of the connecting plate, and a threaded rod is inserted into the insertion hole. One end of the threaded rod is threadedly connected to a threaded hole on the surface of a screw hole seat. The screw hole seat is fixedly installed on the outer wall of the corresponding side of the surveying drone, and an abutting limit knob is fixedly connected to the other end of the threaded rod.

[0012] The beneficial effects of this utility model are as follows: The protective structure for a surveying drone obtained through the above design allows for convenient installation and disassembly, facilitating maintenance and replacement, through the combined design of the upper and lower covers and the coordination of the connecting mechanism. The protective isolation structure and the stable frame structure reliably protect the rotor from impacts by external objects, ensuring the drone's flight safety and enabling the drone to operate stably and efficiently in surveying tasks, thus improving the efficiency and quality of surveying work.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a protective structure for a surveying drone, including a protective net cover 1 covering the outside of the rotors on both sides of the surveying drone 2. The protective net cover 1 includes a pair of oppositely arranged upper cover 101 and lower cover 102, which are detachably connected by fasteners. Both ends of the upper cover 101 and lower cover 102 are arc-shaped structures coaxially arranged with the corresponding rotors of the surveying drone 2, and a protective isolation structure is provided in the hollow part of the arc structure. The two rotors on one side of the surveying drone 2 are located in the internal space formed by the upper cover 101 and lower cover 102. Two parallel connecting rods 107 are integrally arranged on the outer wall of one side of the upper cover 101. Each connecting rod 107 has an integrally arranged connecting slider 108 at its end. Each connecting rod 107 is detachably connected to the connecting mechanism provided on the corresponding side of the outer wall of the surveying drone 2 through the connecting slider 108.

[0021] Please see Figures 2 to 4Both the upper cover 101 and the lower cover 102 include a connecting frame 103 and a structural frame 104. Each structural frame 104 is located on one side of the corresponding connecting frame 103 and the two are arranged in parallel. The area of ​​the structural frame 104 is smaller than that of the connecting frame 103. The two ends of the connecting frame 103 and the structural frame 104 form corresponding arc-shaped structures. Each connecting frame 103 has several evenly distributed connecting holes 106 on its circumferential surface for inserting fasteners.

[0022] The connecting frame 103 serves as the basic structure for connecting the upper cover 101 and the lower cover 102, as well as for connecting the upper cover 101 to the outer wall of the surveying drone 2. The structural frame 104 is located above or below the corresponding connecting frame 103. The protective isolation structure is located between the arc structures at both ends of the connecting frame 103 and the structural frame 104, forming a raised structure between the upper cover 101 and the lower cover 102 to provide normal rotation space for the rotor of the surveying drone 2. The arc structure is coaxial with the rotor rotation axis. In use, the lower cover 102 is first... The lower cover 102 is fitted onto the two rotors on one side of the surveying drone 2, with its overall height lower than that of the rotors. The upper cover 101 is then placed over the two rotors, with the structural frames 104 in the upper cover 101 and the lower cover 102 aligned. At this point, several connecting holes 106 are also aligned one by one. Fasteners are inserted into each set of corresponding connecting holes 106, and nuts are used to limit the connection between the upper cover 101 and the lower cover 102. Finally, the upper cover 101 is connected to the outer wall of the surveying drone 2 via the connecting rod 107 to complete the overall installation.

[0023] Furthermore, a number of protective rods 105 evenly distributed in a ring are integrally provided between the outer walls of the corresponding arc structure at one end of the connecting frame 103 and the corresponding structural frame 104.

[0024] The protective isolation structure consists of several protective rods 105. The protective rods 105 are evenly distributed in a ring around the center of the arc structure of the connecting frame 103 and the structural frame 104. The protective rods 105 are integrally formed with the connecting frame 103 and the structural frame 104 to ensure the stability of the overall structure. The protective rods 105, the connecting frame 103 and the structural frame 104 form an integral whole with a mesh structure at both ends, which isolates the internal and external spaces of the mesh and protects the rotor of the surveying UAV 2.

[0025] Furthermore, the structural frame 104 is an overall closed rod-shaped structure in the middle connected to the ring-shaped structures at both ends.

[0026] The closed rod-shaped structure in the middle of the structural frame 104 effectively supports the protective mesh and maintains its shape stability. It also makes efficient use of space without adding excessive weight, ensuring all-around protection for the rotor and achieving a good balance between the protective performance and structural compactness of the protective mesh. The ring-shaped structures at both ends of the structural frame 104 facilitate fitting the lower cover 102 onto the two corresponding rotors.

[0027] Furthermore, the connecting frame 103, the structural frame 104, and the protective rod 105 are all made of low-weight, high-strength materials.

[0028] The connecting frame 103, structural frame 104, and protective rod 105 can be made of common low-weight, high-strength materials such as carbon fiber, aluminum alloy, and titanium alloy. Carbon fiber has advantages such as low density, high strength, and high modulus, and is widely used in aerospace, sporting goods, and other fields. Aluminum alloy maintains a certain strength while being relatively lightweight and is often used in the automotive and construction industries. Titanium alloy has excellent strength and corrosion resistance and has important applications in medical devices and high-end machinery manufacturing. This design ensures the overall robustness of the protective net cover 1 while relatively reducing the load on the surveying drone 2, thus guaranteeing the protective effect and minimizing usage limitations.

[0029] Furthermore, the connection mechanism includes two connection blocks 109. Each connection block 109 is detachably connected to the outer wall of the corresponding side of the mapping drone 2 by fasteners. Each connection block 109 has a connection groove 110 on one side surface that corresponds to the connection slider 108. Each connection slider 108 is slidably connected in the corresponding connection groove 110. Each connection groove 110 is also slidably connected to an abutment limit block 111. The two abutment limit blocks 111 are connected to the locking mechanism.

[0030] After the upper cover 101 and the lower cover 102 are connected, the two connecting rods 107 on one side of the upper cover 101 are slidably installed through the connecting slider 108 and the connecting grooves 110 on the two connecting blocks 109. After the connecting rods 107 and the connecting slider 108 are installed, the two abutting limit blocks 111 are slidably installed into the corresponding connecting grooves 110, abutting the corresponding connecting slider 108 from above, and the upper cover 101 and the lower cover 102 are connected to the surveying UAV 2 as a whole after being limited by the locking mechanism.

[0031] Furthermore, the locking mechanism includes a connecting plate 112, with both ends of the connecting plate 112 fixedly connected to two abutment limit blocks 111 respectively. The upper surface of the connecting plate 112 is provided with an insertion hole 113, and a threaded rod 114 is inserted into the insertion hole 113. One end of the threaded rod 114 is threadedly connected to a threaded hole in the surface of a screw hole seat 115. The screw hole seat 115 is fixedly installed on the outer wall of the corresponding side of the surveying UAV 2, and the other end of the threaded rod 114 is fixedly connected to an abutment limit knob 116.

[0032] The connecting plate 112 is used to connect two abutment limiting blocks 111. After the abutment limiting blocks 111 are installed in place, the threaded rod 114 in the insertion hole 113 is rotated by the abutment limiting knob 116, so that its bottom end is gradually threaded into the threaded hole opened on the surface of the threaded hole seat 115. Finally, the bottom surface of the abutment limiting knob 116 is tightly abutted against the upper surface of the connecting plate 112 to limit the two abutment limiting blocks 111, ensuring the stability of the upper cover 101 and the lower cover 102 during use.

[0033] Working principle: During installation, the lower cover 102 is first fitted onto the two rotors on one side of the surveying UAV 2, with the overall height of the lower cover 102 lower than the height of the rotors. Next, the upper cover 101 is placed over the two rotors, aligning the structural frames 104 of the upper and lower covers 101. At this point, the connecting holes 106 also correspond one-to-one. Fasteners are inserted into the corresponding connecting holes 106 and secured with nuts, completing the connection between the upper and lower covers 101. Subsequently, the connecting rod 107 on one side of the upper cover 101 is slidably installed through the connecting slider 108 onto the connecting groove 110 on the connecting block 109. Then, the abutment limiting block 111 is slid into the connecting groove 110 to abut against the connecting slider 108 from above, and is secured by a locking mechanism. In the locking mechanism, rotating the abutment limit knob 116 causes the threaded rod 114 to be threaded into the threaded hole of the screw hole seat 115, thereby tightly abutting against the upper surface of the connecting plate 112, realizing the connection between the upper cover 101 and the lower cover 102 and the surveying UAV 2. During flight, the connecting frame 103, structural frame 104, and protective rod 105 in the protective net cover 1 form a stable structure. The protective isolation structure composed of the protective rod 105 can effectively isolate the space inside and outside the net cover, preventing foreign objects from contacting the rotor. At the same time, the structural frame 104 maintains a stable shape and makes reasonable use of space, and the connecting frame 103 ensures that the overall connection foundation is solid. Moreover, these components are made of low-weight, high-strength materials, which reduces the load on the UAV while ensuring the protective effect, ensuring the normal rotation of the rotor and flight safety of the surveying UAV 2.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
