Description

Technical Field

[0001] This utility model belongs to the field of UAV surveying and mapping technology, specifically relating to a rapid fixing and protection device for UAV-borne lidar terrain surveying equipment. Background Technology

[0002] With the rapid development of fields such as geographic information mapping, geological disaster monitoring, and smart city construction, UAV-borne lidar topographic surveying technology has gradually become a core means of topographic data acquisition due to its advantages of high efficiency, accuracy, and flexibility. This technology, using UAVs equipped with lidar surveying equipment, can quickly acquire three-dimensional topographic information of target areas, significantly improving measurement efficiency and data accuracy. It is particularly suitable for scenarios where traditional surveying methods are difficult to cover, such as complex terrain and remote areas.

[0003] In practical applications, on the one hand, the connection structure between existing UAVs and lidar measurement equipment is mostly customized, and the installation process is cumbersome. It requires special tools to fix multiple points, which is not only time-consuming, but also difficult to adjust flexibly according to the size of different models of measurement equipment, resulting in poor versatility. On the other hand, lidar measurement equipment has extremely high requirements for the cleanliness of the working environment. If its laser emission and reception windows are blocked by impurities, it will directly lead to the attenuation or distortion of the measurement signal, which will seriously affect the accuracy of the terrain data. Utility Model Content

[0004] The purpose of this invention is to provide a fast-fixing and protective device for UAV-borne lidar terrain surveying equipment. It can be installed on different models of lidar, has high flexibility, and can provide convenient protection for lidar.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A rapid fixing and protective device for UAV-borne lidar terrain surveying equipment includes a UAV body, rotors mounted on the side walls of the UAV body, a bracket fixedly connected to the bottom of the UAV body, two crossbeams fixedly connected between the brackets, a mounting plate between the two crossbeams, several mounting holes on the top surface of the mounting plate, connecting plates fixedly connected to both ends of the mounting plate, fixing components between the two ends of the connecting plates and the crossbeams, and two support rods on the upper side of each crossbeam, with protective components mounted on the support rods.

[0007] Furthermore, the fixing component includes bent plates fixedly connected to both ends of the connecting plate, each bent plate having a positioning bolt threaded to its sidewall, and the crossbeam having a plurality of screw holes on its sidewall, the positioning bolts being threadedly connected to the screw holes.

[0008] Furthermore, the protective assembly includes two connecting rods, which are respectively mounted on two support rods on the same side, and multiple protective nets are provided between the two support rods.

[0009] Furthermore, the support rod and the bent plate are connected by locking bolts.

[0010] Furthermore, the side wall of the connecting rod is provided with several through holes, two of which are into which fixing bolts are inserted, and the fixing bolts are threadedly connected to the support rod.

[0011] Furthermore, hooks are fixedly connected to both ends of the protective net, and the hooks are connected to the through holes.

[0012] Furthermore, the protective net is made of stainless steel or plastic mesh.

[0013] The technical effects achieved by this utility model are as follows:

[0014] The rapid fixing and protection device for UAV-borne lidar terrain surveying equipment of this utility model, through the cooperation between the mounting plate, fixing components and connecting plate, and the multiple mounting holes on the mounting plate, can meet the installation of radar equipment of different specifications, with high versatility, and can be easily fixed to the UAV body with the fixing components.

[0015] This utility model's rapid fixing and protection device for UAV-borne lidar topographic surveying equipment, through the cooperation between the UAV body, crossbeam, and protective components, allows for flexible adjustment of the protective net's position according to protection requirements. This effectively protects the radar equipment by directly blocking impurities such as leaves, dust, and insects carried by the rotor airflow from contacting the surface of the measuring equipment. This prevents impurities from obstructing the laser emission and reception windows, fundamentally reducing measurement signal attenuation or distortion, and ensuring the accuracy of topographic surveying data.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, the rapid fixing and protection device for UAV-borne lidar terrain surveying equipment includes a UAV body 1, a rotor 2 mounted on the side wall of the UAV body 1, a bracket 3 fixedly connected to the bottom of the UAV body 1, two crossbeams 4 fixedly connected between the brackets 3, an installation plate 8 between the two crossbeams 4, several installation holes 9 opened on the top surface of the installation plate 8, connecting plates 7 fixedly connected to both ends of the installation plate 8, fixing components are set between the two ends of the connecting plates 7 and the crossbeams 4, and two support rods 13 are set on the upper side of each crossbeam 4, with protective components set on the support rods 13.

[0024] like Figure 2 and Figure 3 As shown, the fixing component includes bent plates 6 fixedly connected to both ends of the connecting plate 7. The side walls of the bent plates 6 are threaded with positioning bolts 10. The side walls of the crossbeam 4 are provided with several screw holes 5, and the positioning bolts 10 are threadedly connected to the screw holes 5.

[0025] The U-shaped bending plate 6 is easy to hang on the two side beams 4. In addition, the locking method of the positioning bolts 10 and screw holes 5 can prevent the mounting plate 8 from lateral displacement, thereby improving its stability.

[0026] like Figure 2 and Figure 3 As shown, the protective assembly includes two connecting rods 14, which are respectively mounted on two support rods 13 on the same side. Multiple protective nets 17 are arranged between the two support rods 13. Hooks 12 are fixedly connected to both ends of the protective nets 17, and the hooks 12 are connected to the through holes 16.

[0027] The protective netting 17 is made of stainless steel or plastic mesh. It possesses good flexibility to resist the impact of falling objects, while also exhibiting good strength and a long service life.

[0028] Specifically, multiple protective nets 17 are provided, and users can adjust the protection range of each protective net 17 according to their protection needs. During the flight of the drone body 1, the airflow generated by its rotor 2 will disturb and disperse impurities such as leaves and insects. The protective nets 17 can block the impurities from falling from above, thereby protecting the radar equipment and improving the measurement accuracy of the radar equipment.

[0029] like Figure 3 As shown, the support rod 13 is connected to the bending plate 6 by a locking bolt 11. The angle of the support rod 13 can be adjusted by tightening or loosening the locking bolt 11, which facilitates the adjustment of the height and range of the protective net 17, thereby improving the flexibility of use.

[0030] like Figure 2 and Figure 4 As shown, the connecting rod 14 has several through holes 16 on its side wall, two of which are into which fixing bolts 15 are inserted. The fixing bolts 15 are threadedly connected to the support rod 13. The position of the connecting rod 14 can be flexibly adjusted using the fixing bolts 15, allowing for targeted protection. For example, if the protection range on the left side needs to be extended, the connecting rod 14 can be extended to the left to a certain length, and a protective net 17 can be installed for protection.

[0031] The working principle of this utility model is as follows: First, the bent plate 6 is clamped on the two side crossbeams 4 and the positioning bolts 10 are tightened so that they are inserted into the corresponding screw holes 5 to fix the mounting plate 8. Then, the radar equipment is placed under the mounting plate 8 and screws are inserted into the corresponding mounting holes 9 to fix the radar equipment. Next, the angle of the support rod 13 is adjusted by tightening the locking bolts 11, and then the connecting rod 14 is assembled by using the fixing bolts 15. After that, the protective net 17 is hung in the through hole 16 by the hooks 12 to complete the protection of the radar equipment.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
