Description

Technical area

[0001] The utility model relates to an unmanned aerial vehicle and in particular to a UAV for geographical surveying of coastal terrain. Background technology

[0002] With the continuous development of drone technology, its applications are becoming increasingly widespread in many fields, especially in the field of geographical surveying. However, conventional quadrotor UAVs often encounter problems with insufficient stability and buffer capacity when conducting geographical surveying operations. In complex and variable environments, such as coastal areas, the UAV is exposed to external shocks and vibrations during landing, which not only affects the accuracy of the geographical survey data but can also cause damage to the quadrotor UAV itself.

[0003] Therefore, there is an urgent need in the market for a better UAV for geographical surveying of coastal terrain. Content of the utility model

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned technology and to provide a UAV for geographical surveying of coastal terrain.

[0005] To solve the above-mentioned technical problems, the utility model represents a UAV for geographical surveying of coastal terrain: It comprises a quadrotor UAV. Geographical surveying equipment is attached to the underside of the quadrotor UAV.

[0006] The four sides of the quadrotor UAV are secured with buffer mechanisms.

[0007] The buffer mechanism includes a side support frame, which is fixed to the side of the quadrotor UAV. The body of the side support frame is provided with an inner side support plate.

[0008] The upper end of the inner support plate is provided with an upper support arm, and the lower end of the inner support plate is provided with a lower support arm.

[0009] The end of the lower support arm and the end of the upper support arm rotate together and are provided with an outer support plate.

[0010] The upper end of the outer lateral support plate is articulated with the upper spring damper through a joint connection, and the lower end of the outer lateral support plate is articulated with the outer support arm through a joint connection. The end of the outer support arm and the end of the upper spring damper are rotated together and fitted with the outer support plate. The outer support plate and the lower support arm are connected by the middle spring damper. The outer support plate is rigidly fitted with the external spring damper.

[0011] The inner support plate is arranged vertically.

[0012] The extension direction of the lower support arm and the extension direction of the upper support arm are parallel to each other.

[0013] The inner support plate, the upper support arm, the lower support arm and the outer support plate form a parallelogram structure.

[0014] The lower end of the external spring damper is provided with support feet.

[0015] The advantages of the utility model over the prior art are that stability and buffering are provided by the buffer mechanism: The buffer mechanism designed for this quadrotor UAV significantly increases stability during flight, especially in complex environments or sudden situations. Flexibility of parallelogram structures: The parallelogram structure consisting of the inner support plate, upper support arm, lower support arm, and outer support plate is not only robust but also highly flexible. This design allows the structure to undergo a certain degree of elastic deformation when subjected to external forces, effectively absorbing and dispersing impact forces and preventing the drone from serious damage in the event of a collision.

[0016] Excellent shock absorption effect of the spring damper: Components such as the upper spring damper and the external spring damper utilize the properties of the spring and damping materials to effectively reduce the vibrations generated by the UVA during landing or collision. This design not only protects the precision instruments inside the UVA but also ensures the normal operation of the geospatial equipment in bumpy or unexpected situations.

[0017] Comprehensive protection for UAVs and geographic surveying equipment: The integration of multiple spring dampers provides the UAV with excellent damping during landing or collision. This comprehensive protection significantly extends the service life of the UAV. Description with drawings

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model are described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0023] A UAV for geographical surveying of coastal terrain in conjunction with the attached drawings includes quadrotor UAV 101. Geographical surveying equipment 102 is attached to the underside of the quadrotor UAV 101.

[0024] The four sides of the quadrotor UAV 101 are secured with buffer mechanisms 200.

[0025] The buffer mechanism 200 includes a side support frame 201, and the side support frame 201 is fixedly arranged on the side of the quadrotor UAV 101. The body of the side support frame 201 is provided with an inner side support plate 202. The inner support plate 202 is arranged vertically. The upper end of the inner support plate 202 is provided with an upper support arm 203, and the lower end of the inner support plate 202 is provided with a lower support arm 204. The extending direction of the lower support arm 204 and the extending direction of the upper support arm 203 are parallel to each other. The end of the lower support arm 204 and the end of the upper support arm 203 rotate together and are provided with an outer support plate 205. The inner support plate 202, the upper support arm 203, the lower support arm 204 and the outer support plate 205 form a parallelogram structure.The upper end of the outer lateral support plate 205 is articulated with the upper spring damper 206 through a joint connection mode, and the lower end of the outer lateral support plate 205 is articulated with the outer support arm 207 through a joint connection mode. The end of the outer support arm 207 and the end of the upper spring damper 206 are rotated together and provided with the outer support plate 208. The outer support plate 208 and the lower support arm 204 are connected by the middle spring damper 209. The outer support plate 208 is fixedly provided with the external spring damper 210. The lower end of the external spring damper 210 is provided with support feet 211. It has a very good damping effect.

[0026] The specific structure of the buffer mechanism 200 is as follows: First, the main frame of the buffer mechanism 200 consists of a side support frame 201, which is stably installed on the side of the quadrotor UAV 101. An inner support plate 202 is provided on the side support frame 201, and the plate is in a vertical state.

[0027] The upper and lower ends of the inner support plate 202 are each connected to an upper support arm 203 and a lower support arm 204. The extension directions of the two support arms are parallel to each other. A rotatable outer support plate 205 is jointly connected to the end of the lower support arm 204 and the end of the upper support arm 203. Thus, the inner support plate 202, the upper support arm 203, the lower support arm 204, and the outer support plate 205 form a parallelogram structure that can be flexibly deformed to a certain extent to adapt to different collisions and collisions.

[0028] Furthermore, the upper end of the outer support plate 205 is connected to an upper spring damper 206 via a hinge connection. At the same time, the lower end of the outer support plate 205 is also connected to an outer support arm 207 via a hinge connection. The end of the outer support arm 207 and the end of the upper spring damper 206 are jointly connected to a rotatable outer support plate 208.

[0029] Furthermore, the outer support plate 208 and the lower support arm 204 are connected via a central spring damper 209 to increase the buffering effect. An outer spring damper 210 is also attached to the outer support plate 208, with a support foot 211 provided at its lower end.

[0030] The utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited thereto.
