Description

Technical Field

[0001] The utility model relates to the technical field of geographic information measurement, in particular to a spatial planning topographic surveying device. Background Art

[0002] Topographic surveying plays a vital role in national land space planning. It accurately measures the projection position and elevation of objects and terrain on the horizontal plane, and draws topographic maps at a certain scale, providing rich data support for the rational use and planning of land resources. One of the main means of topographic surveying is aerial photogrammetry, which uses professional photographic equipment carried by aircraft to photograph the ground, combined with ground control points, mapping and stereo mapping technologies, to achieve efficient and accurate topographic map production. The basic principle of aerial photogrammetry lies in the perspective transformation of central projection and the geometric inversion of the projection process, which ensures the accuracy and reliability of the measurement results.

[0003] In recent years, with the rapid development of UAV technology, the application of UAV in the field of topographic surveying has become increasingly widespread. With its high efficiency, precision and flexibility, UAVs have greatly improved the efficiency and accuracy of topographic surveying and have been widely favored by the industry. However, UAVs still face some challenges in practical applications, such as collision damage and falling due to insufficient power supply. These problems not only increase the cost of measurement, but may also have a negative impact on measurement accuracy and efficiency. Therefore, how to fully utilize the advantages of UAVs in topographic surveying while ensuring their safe and stable operation is an important issue that needs to be solved at present.

[0024] By adopting the above technical solution, when the UAV 1 collides or is about to fall due to insufficient power, the telescopic rod 16 drives the folding wings 23 to unfold quickly by controlling the movement of the gear block 17, thereby slowing down the falling speed of the UAV 1 by increasing air resistance, and driving the UAV 1 to glide, further reducing the impact force with the ground, thereby reducing the degree of damage to the UAV 1. When the UAV 1 falls to the water surface, the folding airbag 10 will be quickly inflated by the high-pressure gas cylinder 8 in a short time to form a buoyancy support structure. This structure can effectively support the buoyancy of the UAV 1 on the water surface and prevent the UAV 1 from sinking to the bottom of the water. At the same time, the folding airbag 10 is used in conjunction with the folding wings 23 to further improve the stability of the UAV 1 on the water surface and ensure the safety of the UAV 1 after falling.

[0025] The gear set includes a tooth block 17 fixedly connected to the telescopic end of the telescopic rod 16, gears 19 are symmetrically arranged on both sides of the tooth block 17 inside the top seat 15, the bottom end of the connecting block 21 passes through the top seat 15 and is fixedly connected to the gear 19, the gear 19 is meshed with the tooth block 17, a fixed clamping block 18 is fixedly connected to the inner side of the top seat 15, an opening is penetrated on one side of the tooth block 17, and the fixed clamping block 18 is clamped inside the opening of the tooth block 17 to limit the movement of the tooth block 17.

[0026] By adopting the above technical solution, the telescopic end of the telescopic rod 16 contracts. When the telescopic end contracts, it will pull the tooth block 17 to move. When the tooth block 17 moves, it will drive the gear 19 to rotate. The rotation of the gear 19 will drive the connecting block 21 to rotate. The rotation of the connecting block 21 will drive the driving rod 22 out from under the top plate 20.

[0027] A control valve 13 is provided inside the gas cylinder compartment 7 near the high-pressure gas cylinder 8, one end of the high-pressure gas cylinder 8 is connected to the control valve 13, a connecting pipe 14 is fixedly connected to one side of the control valve 13, one end of the connecting pipe 14 is fixedly connected to the folding airbag 10, a protective plate 12 is provided inside the base 6 near the folding airbag 10, and limiting slide grooves 9 are symmetrically provided on both sides of the base 6, and sliders 11 are fixedly connected to the limiting slide grooves 9 at both ends of one side of the folding airbag 10, and the slider 11 is adapted to the limiting slide groove 9 and is slidably connected.

[0028] By adopting the above technical solution, the control valve 13 in the gas cylinder compartment of the base 6 will open automatically. When the control valve 13 is opened, the high-pressure gas in the high-pressure gas cylinder 8 will enter the folding airbag 10 through the connecting pipe 14. When a large amount of gas enters the folding airbag 10, it will quickly unfold and expand. One side of the folding airbag 10 is fixedly connected to the base 6, and the other side is slidably connected to the limiting slide groove 9 through the slider 11. When the folding airbag 10 is unfolded, it will only unfold inside the base 6 due to the restriction of the slider 11.

[0029] The working principle of the utility model is that in actual application, the drone may fall due to collision damage and insufficient power. When in use, the measuring camera 2 is installed at the bottom of the drone 1, and then the protective cover 3 is put on the outside of the measuring camera 2 and fixed to the drone 1. The protective cover 3 is made of transparent material. Then the drone 1 can be lifted into the air and drive the measuring camera 2 to take pictures. When the drone 1 is hit or falls due to insufficient power, the attitude sensor 4 detects that the drone 1 is unbalanced, and first controls the telescopic end of the telescopic rod 16 to contract. When the telescopic end contracts, it will pull the tooth block 17 to move. When the tooth block 17 moves, it will drive the gear 19 to rotate. The rotation of the gear 19 will drive the connecting block 21 to rotate. The rotation of the connecting block 21 will drive the driving rod 22 to come out from under the top plate 20. One side of the folding wing 23 is fixed to the driving rod 22, and the other side is fixed to the top plate 20. When the driving rod 22 moves, it will pull the folding wing 23 to unfold. The maximum opening angle of the driving rod 22 is 140 degrees. When the folding wing 23 is unfolded, the air resistance is increased to slow down the drone 1. The falling speed is increased, and the UAV 1 is driven to glide, further reducing the impact force with the ground, thereby reducing the damage to the UAV. At the same time, the control valve 13 in the gas cylinder compartment of the base 6 will automatically open. When the control valve 13 is opened, the high-pressure gas in the high-pressure gas cylinder 8 will enter the folding airbag 10 through the connecting pipe 14. When a large amount of gas enters the folding airbag 10, it will quickly expand. One side of the folding airbag 10 is fixedly connected to the base 6, and the other side is slidably connected to the limiting slide groove 9 through the slider 11. When the folding airbag 10 is unfolded, it will only be unfolded inside the base 6 through the restriction of the slider 11. The folding airbag 10 is used in conjunction with the folding wing 23. When the UAV 1 falls to the water surface, the folding airbag 10 will be quickly inflated by the high-pressure gas cylinder 8 in a short time to form a buoyancy support structure. This structure can effectively support the buoyancy of the UAV 1 on the water surface and prevent the UAV 1 from sinking to the bottom of the water. At the same time, the folding airbag 10 is used in conjunction with the folding wing 23 to further improve the stability of the UAV 1 on the water surface and ensure the safety of the UAV 1 after falling.
