[0002] Aerial survey modeling is a further application of UAVs. It combines radio remote control equipment or airborne computer remote control flight and other advanced technologies such as automatic photogrammetry and GPS automatic positioning to achieve rapid acquisition and synchronous processing of aerial remote sensing data. UAV aerial survey has the characteristics of fast aerial survey response capability, outstanding timeliness and cost-effectiveness, limited monitoring area, and fast ground data acquisition and modeling capabilities. The UAV pod integrates related electrical devices, cameras, lidar and other visual and position sensing components. Usually the pod is installed on the belly of the fuselage.

[0003] There are many types of such pod devices on the market today, which can basically meet people's usage needs, but there are still certain shortcomings. The existing pod devices of this type are installed on the belly of the drone. Since the pod is an external accessory, this results in the pod directly contacting the ground after the drone lands. During this process, the electrical components inside the pod are subject to a large impact from the landing. After the drone rises and falls for a long time, the internal components may be damaged, making it difficult to ensure the service life of the pod. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figures 1 to 4 A pod device for large-scale unmanned aerial survey equipment comprises a mounting seat 1, a pod body 2, a first support frame 3, and a second support frame 4; the pod body 2 is arranged at the bottom of the mounting seat 1, and the number of the first support frame 3 and the second support frame 4 is two, the two first support frames 3 are symmetrically arranged at the left ends of the front and rear sides of the mounting seat 1, and the two second support frames 4 are symmetrically arranged at the right ends of the front and rear sides of the mounting seat 1, the first support frame 3 and the second support frame 4 are parallel to each other, and the first support frames 3 and the second support frames 4 on both sides of the mounting seat 1 are staggered; a group of bidirectional motors 5 are arranged inside the interlayer of the mounting seat 1, and the front and rear output ends of the group of bidirectional motors 5 are respectively provided with rotating shafts 6 fixedly connected to the first support frame 3 and the second support frame 4.

[0018] In this embodiment: a group of first brackets 3 and a group of second brackets 4 are arranged at the front and rear ends of both sides of the mounting seat 1 through the rotating shaft 6. When the drone falls, the bidirectional motor 5 is started, and the rotating shaft 6 drives the first bracket 3 and the second bracket 4 to rotate and be perpendicular to the ground. When the first bracket 3 and the second bracket 4 are perpendicular to the ground, the bottom of the first bracket 3 and the second bracket 4 is much lower than the bottom of the pod body 2, and there is no need to adjust the body posture of the drone as a whole. After the drone hovers, the pod body 2 is in a suspended state with the ground, which can avoid the landing impact of the pod body 2 and other components, effectively extending the service life of the pod device, and the first bracket 3 and the second bracket 4 are both composed of a support rod 7 and a buffer rod 8. The buffer rod 8 enables the first bracket 3 and the second bracket 4 to have a buffering and shock-absorbing function, which can avoid damage to the electrical components inside the pod body 2, and effectively extend the service life of the pod device; when the drone is flying, the bidirectional motor 5 is started, and the rotating shaft 6 drives the first bracket 3 and the second bracket 4 to rotate and be parallel to the mounting seat 1, and the pod body 2 can rotate normally for shooting without being blocked by the first bracket 3 and the second bracket 4.

[0019] As a technical optimization solution of the utility model, the first support frame 3 and the second support frame 4 have the same composition and function. The first support frame 3 is composed of a support rod 7 and a buffer rod 8 arranged at one end of the support rod 7, and the other end of the support rod 7 is arranged on the outer wall of the rotating shaft 6.

[0020] In this embodiment, the rotating shaft 6 drives the supporting rod 7 and the buffer rod 8 to rotate perpendicular to the ground, so that the pod body 2 can be suspended in the air to avoid contact with the ground.

[0021] As a technical optimization scheme of the utility model, the buffer rod 8 includes a buffer sleeve 9, a spring ring 10, a connecting rod 11, and a support seat 12. The buffer sleeve 9 is arranged on the support rod 7, one end of the connecting rod 11 is arranged on the support seat 12, and the other end of the connecting rod 11 is inserted into the buffer sleeve 9. The two ends of the spring ring 10 are respectively arranged in the buffer sleeve 9 and on the support seat 12, and the connecting rod 11 is sleeved in the spring ring 10.

[0022] In this embodiment: the spring in the buffer tube elastically supports the support seat 12, and the connecting rod 11 plays a guiding role. When the support seat 12 is vibrated, the spring flexibly expands and contracts in the buffer tube, and the spring elastically supports the support seat 12 through the connecting rod 11, which can reduce the impact force of the first support frame 3 and the second support frame 4. The first support frame 3 and the second support frame 4 are in contact with the ground, avoiding damage to the electrical components inside the pod body 2, and effectively extending the service life of the pod device.

[0023] As a technical optimization solution of the present invention, a rubber pad 13 is provided on a side of the support seat 12 away from the connecting rod 11 .

[0024] In this embodiment, the rubber pad 13 also has elastic properties to reduce the vibration force generated when the support base 12 contacts the ground.

[0025] As a technical optimization solution of the utility model, a distance sensor 14 and a PLC controller 15 are arranged at the bottom of the mounting base 1 , and the PLC controller 15 is electrically connected to the distance sensor 14 and the bidirectional motor 5 .

[0026] In this embodiment: when the drone falls (before the drone hovers), the distance sensor 14 monitors the distance from the ground. When the distance is lower than the set value, the PLC controller 15 controls the bidirectional motor 5 to be energized, and the rotating shaft 6 drives the first support frame 3 and the second support frame 4 to rotate and be perpendicular to the ground, so that the drone can hover safely; similarly, when the drone's flight altitude is higher than the set value, the first support frame 3 and the second support frame 4 are rotated to be parallel to the mounting base 1 to prevent the first support frame 3 and the second support frame 4 from blocking the pod body 2.

[0027] Working principle: when the drone is falling, the distance sensor 14 monitors the distance from the ground. When the distance is lower than the set value, the PLC controller 15 controls the bidirectional motor 5 to be energized, and the rotating shaft 6 drives the first support frame 3 and the second support frame 4 to rotate and be perpendicular to the ground. When the first support frame 3 and the second support frame 4 are perpendicular to the ground, the bottom of the first support frame 3 and the second support frame 4 is much lower than the bottom of the pod body 2. There is no need to adjust the drone's body posture as a whole. After the drone is hovering, the pod body 2 is in a suspended state with the ground, which can avoid the landing impact on the pod body 2 and other components, and the buffer rod 8 can avoid damage to the electrical components inside the pod body 2 when the drone falls, effectively extending the service life of the pod device; when the drone is flying, start the bidirectional motor 5, the rotating shaft 6 drives the first support frame 3 and the second support frame 4 to rotate and be parallel to the mounting base 1, and the pod body 2 can rotate normally for shooting without being blocked by the first support frame 3 and the second support frame 4.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
