Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying technology, and in particular to a UAV for land surveying. Background Technology

[0002] When drones are used to survey land, they typically carry camera equipment to take aerial photos and then transmit the images back to the ground for monitoring and management. During the photo-taking process, the camera equipment is usually positioned below the drone to obtain a better field of view.

[0003] Chinese utility model patent CN219487741U discloses an aerial surveying drone for land mapping, including a drone body, a storage base at the bottom of the drone body, an aerial surveying camera at the bottom of the storage base, an annular storage groove inside the storage base, and a storage protection component inside the annular storage groove, the storage protection component including a protective outer cylinder disposed inside the annular storage groove.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the aerial survey camera used for taking pictures in the above-mentioned device is fixedly installed on the bottom surface of the drone body. During the drone shooting process, since the aerial survey camera is fixedly installed on the bottom surface of the drone body, the angle of the aerial survey camera is fixed, making it impossible to shoot a larger area of ​​land, thereby increasing the limitations of the device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a drone for land surveying.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a land surveying drone, including a drone body, connecting arms arranged in an array on the side wall of the drone body, each of the connecting arms being provided with a wing, a landing gear being provided on the bottom surface of the drone body, a surveying camera being provided on the bottom surface of the drone body, and an adjustment device for adjusting the angle of the surveying camera being provided on the bottom surface of the drone body, the adjustment device including an X-axis adjustment mechanism and a Y-axis adjustment mechanism.

[0007] By adopting the above technical solution, when staff need to survey land, they need to activate the drone, causing its wings to work and lift the drone into the air, allowing the surveying camera to photograph the land. The captured images are then uploaded. During this process, if staff need to adjust the angle of the surveying camera, they need to activate the adjustment device to adjust the angle of the camera, thereby photographing a larger area of ​​land and reducing the limitations of the device.

[0008] Furthermore, the X-axis adjustment mechanism includes a support frame fixedly mounted on the bottom surface of the UAV body. The bottom surface of the support frame has a spherical groove. The X-axis adjustment mechanism also includes a spherical component rotatably mounted in the spherical groove, a first motor fixedly mounted on the side wall of the support frame, a first arc-shaped component fixedly mounted on the end of the output shaft of the first motor, a connecting rod mounted on the spherical component, and a connecting plate fixedly mounted on the bottom surface of the connecting rod. The mapping camera is fixed to the connecting plate. The first arc-shaped component has a first arc-shaped groove extending through it. The connecting rod passes through the first arc-shaped groove and matches the first arc-shaped groove. The output shaft of the first motor passes through the support frame and is fixed to the first arc-shaped component.

[0009] Furthermore, the surface of the spherical component is provided with a connecting groove, and the Y-axis adjustment mechanism includes a connector that is slidably disposed in the connecting groove, a second motor that is fixedly disposed on the side wall of the support frame, and a second arc-shaped component that is fixedly disposed at the end of the output shaft of the second motor. A second arc-shaped groove is provided through the second arc-shaped component, and the connecting rod passes through the second arc-shaped groove and matches the second arc-shaped groove. The connecting rod and the connector are fixed to each other.

[0010] By adopting the above technical solution, when the operator needs to adjust the X-axis angle, the first motor is activated, causing its output shaft to rotate. This, in turn, causes the first arc-shaped component to rotate, which in turn causes the connecting rod to rotate along the second arc-shaped groove. Consequently, the connecting plate, connecting component, and spherical component rotate under the action of the connecting rod, thus changing the X-axis angle of the surveying camera under the action of the connecting plate. Subsequently, when the operator needs to adjust the Y-axis angle, the second motor is activated, causing its output shaft to rotate. This, in turn, causes the second arc-shaped component to rotate, which in turn causes the connecting rod to rotate along the first arc-shaped groove under the action of the second arc-shaped groove. This, in turn, causes the connecting component to slide along the connecting groove under the action of the connecting rod, thus causing the connecting plate to rotate under the action of the connecting rod. Consequently, the Y-axis angle of the surveying camera changes under the action of the connecting plate, allowing for the imaging of a larger area of ​​land and reducing the limitations of the device.

[0011] Furthermore, the connector has an arc-shaped surface at one end near the first arc-shaped component, and the arc-shaped surface matches the inner wall of the first arc-shaped component.

[0012] By adopting the above technical solution, when the connector slides along the connecting groove under the action of the connecting rod, the arc-shaped surface slides relative to the inner wall of the first arc-shaped component. During this process, the arc-shaped surface reduces the probability of the connector wobbling during sliding, thereby improving the stability of the device. In addition, the arc-shaped surface abuts against the inner wall of the first arc-shaped component, and the connector abuts against the spherical component, further reducing the probability of the spherical component wobbling, thus improving the stability of the device.

[0013] Furthermore, the support frame has two rotating slots, and a rotating rod is rotatably installed in each of the two rotating slots. The two rotating rods are respectively fixed to the first arc-shaped component and the second arc-shaped component.

[0014] By adopting the above technical solution, when the first arc-shaped component and the second arc-shaped component rotate, the rotating rod rotates under the action of the first arc-shaped component and the second arc-shaped component. In this process, the rotating rod reduces the probability of swaying during the rotation of the first arc-shaped component and the second arc-shaped component, thereby improving the stability of the device.

[0015] Furthermore, both the first motor and the second motor are electrically connected to the battery installed inside the drone body.

[0016] By adopting the above technical solution, both the first motor and the second motor are electrically connected to the battery installed inside the drone body, eliminating the need for additional batteries and thus improving the practicality of the device.

[0017] Furthermore, a protective cover is fixedly installed on the bottom surface of the drone body, and the protective cover is made of acrylic sheet material.

[0018] Furthermore, the protective cover has multiple heat dissipation holes.

[0019] By adopting the above technical solutions, the protective cover reduces the probability of camera shake during flight, thereby improving stability. Furthermore, the heat dissipation holes reduce the probability of overheating and damage to the first and second motors, thus extending the lifespan of the device.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when staff need to survey land, they need to activate the drone, causing the wings to work and lift the drone into the air, allowing the surveying camera to photograph the land. The captured images are then uploaded. During this process, if staff need to adjust the angle of the surveying camera, they need to activate the adjustment device to adjust the angle of the camera, thereby photographing a larger area of ​​land and reducing the limitations of the device.

[0022] 2. In this application, when the operator needs to adjust the X-axis angle, the operator needs to start the first motor, which in turn rotates the output shaft of the first motor. This causes the first arc-shaped component to rotate under the action of the first motor output shaft, which in turn causes the connecting rod to rotate along the second arc-shaped groove under the action of the first arc-shaped component. This causes the connecting plate, connecting component, and spherical component to rotate under the action of the connecting rod, thereby changing the X-axis angle of the surveying camera under the action of the connecting plate. Subsequently, when the operator needs to adjust the Y-axis angle, the operator needs to start the second motor, which in turn rotates the output shaft of the second motor. This causes the second arc-shaped component to rotate under the action of the second motor output shaft, which in turn causes the connecting rod to rotate along the first arc-shaped groove under the action of the second arc-shaped groove. This causes the connecting component to slide along the connecting groove under the action of the connecting rod, thereby causing the connecting plate to rotate under the action of the connecting rod. This causes the Y-axis angle of the surveying camera to change under the action of the connecting plate, thus enabling the imaging of a larger area of ​​land and reducing the limitations of the device.

[0023] 3. In this application, when the connector slides along the connecting groove under the action of the connecting rod, the arc-shaped surface slides relative to the inner wall of the first arc-shaped component. During this process, the arc-shaped surface reduces the probability of the connector wobbling during sliding, thereby improving the stability of the device. Furthermore, the arc-shaped surface abuts against the inner wall of the first arc-shaped component, and the connector abuts against the spherical component, further reducing the probability of the spherical component wobbling, thus improving the stability of the device.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-5 As shown in the illustration, this application discloses a land surveying drone, including a drone body 1, connecting arms 11, wings 12, landing gear 13, a surveying camera 14, an X-axis adjustment mechanism 2, and a Y-axis adjustment mechanism 3. Multiple connecting arms 11 are arranged in an array on the side wall of the drone body 1, and multiple wings 12 are respectively mounted on multiple connecting arms 11. The landing gear 13 is mounted on the bottom surface of the drone body 1, and the surveying camera 14 is mounted on the bottom surface of the drone body 1 for photographing and surveying the land. The adjustment mechanism is mounted on the bottom surface of the drone body 1 for adjusting the angle of the surveying camera 14, and includes the X-axis adjustment mechanism 2 and the Y-axis adjustment mechanism 3.

[0032] When staff need to survey the land, they need to activate the drone, causing the wings 12 to work and lift the drone body 1 into the air, allowing the surveying camera 14 to photograph the land. The captured images are then uploaded. During this process, if staff need to adjust the angle of the surveying camera 14, they need to activate the adjustment device to adjust the angle of the camera 14, thereby photographing a larger area of ​​land and reducing the limitations of the device.

[0033] The X-axis adjustment mechanism 2 includes a support frame 21, a spherical component 22, a first motor 23, a first arc-shaped component 24, a connecting rod 25, and a connecting plate 26. The support frame 21 is fixedly mounted on the bottom surface of the UAV body 1, and a spherical groove 27 is formed on the bottom surface of the support frame 21. The spherical component 22 is rotatably mounted within the spherical groove 27. The first motor 23 is fixedly mounted on the side wall of the support frame 21, with its output shaft axis horizontal. The first arc-shaped component 24 is fixedly mounted at the end of the output shaft of the first motor 23, and a first arc-shaped groove 28 is formed through the first arc-shaped component 24. The output shaft of the first motor 23 passes through the support frame 21 and is fixed to the first arc-shaped component 24. The connecting rod 25 is mounted on the spherical component 22, passes through the first arc-shaped groove 28, and matches the first arc-shaped groove 28. The connecting plate 26 is fixedly mounted on the bottom surface of the connecting rod 25, and the mapping camera 14 is fixed to the connecting plate 26.

[0034] The spherical component 22 has a connecting groove 34 on its surface. The Y-axis adjustment mechanism 3 includes a connecting component 31, a second motor 32, and a second arc-shaped component 33. The connecting component 31 is slidably disposed within the connecting groove 34, and the connecting rod 25 is fixed to the connecting component 31. The second motor 32 is fixedly disposed on the side wall of the support frame 21, and its output shaft axis is horizontal. The second arc-shaped component 33 is fixedly disposed at the end of the output shaft of the second motor 32. A second arc-shaped groove 35 is formed through the second arc-shaped component 33, and the connecting rod 25 passes through the second arc-shaped groove 35 and matches the second arc-shaped groove 35.

[0035] When the operator needs to adjust the X-axis angle, the operator needs to start the first motor 23, which will cause the output shaft of the first motor 23 to rotate. This will cause the first arc-shaped component 24 to rotate under the action of the output shaft of the first motor 23, which will cause the connecting rod 25 to rotate along the second arc-shaped groove 35 under the action of the first arc-shaped component 24. This will cause the connecting plate 26, the connecting component 31, and the spherical component 22 to rotate under the action of the connecting rod 25, which will cause the X-axis angle of the surveying camera 14 to change under the action of the connecting plate 26. Subsequently, when the staff needs to adjust the Y-axis angle, they need to start the second motor 32, which in turn causes the output shaft of the second motor 32 to rotate. This causes the second arc-shaped component 33 to rotate under the action of the output shaft of the second motor 32, which in turn causes the connecting rod 25 to rotate within the first arc-shaped groove 28 under the action of the second arc-shaped groove 35. This causes the connecting component 31 to slide within the connecting groove 34 under the action of the connecting rod 25, which in turn causes the connecting plate 26 to rotate under the action of the connecting rod 25. This causes the Y-axis angle of the surveying camera 14 to change under the action of the connecting plate 26, thereby capturing images of a larger area of ​​land and reducing the limitations of the device.

[0036] To improve the stability of the device, the end of the connector 31 near the first arc-shaped member 24 is provided with an arc-shaped surface 4, which matches the inner wall of the first arc-shaped member 24. When the connector 31 slides along the connecting groove 34 under the action of the connecting rod 25, the arc-shaped surface 4 slides relative to the inner wall of the first arc-shaped member 24. During this process, the arc-shaped surface 4 reduces the probability of the connector 31 wobbling during sliding, thereby improving the stability of the device. In addition, the arc-shaped surface 4 abuts against the inner wall of the first arc-shaped member 24, and the connector 31 abuts against the spherical member 22, further reducing the probability of the spherical member 22 wobbling, thereby improving the stability of the device.

[0037] To improve the stability of the device, two rotating slots 5 are provided on the support frame 21, and rotating rods 51 are rotatably installed in each of the two rotating slots 5. The two rotating rods 51 are fixed to the first arc-shaped member 24 and the second arc-shaped member 33, respectively. When the first arc-shaped member 24 and the second arc-shaped member 33 rotate, the rotating rods 51 rotate under the action of the first arc-shaped member 24 and the second arc-shaped member 33. In this process, the rotating rods 51 reduce the probability of swaying during the rotation of the first arc-shaped member 24 and the second arc-shaped member 33, thereby improving the stability of the device.

[0038] To improve the practicality of the device, both the first motor 23 and the second motor 32 are electrically connected to a battery installed inside the drone body 1. Since both the first motor 23 and the second motor 32 are electrically connected to a battery installed inside the drone body 1, no additional power supply is required, thus improving the device's usability.

[0039] To extend the lifespan of the device, a protective cover 6 is fixedly installed on the bottom surface of the drone body 1. The protective cover 6 is made of acrylic sheet and has multiple heat dissipation holes 7 running through it. The protective cover 6 reduces the probability of shaking during flight of the mapping camera 14, thereby improving stability. In addition, the heat dissipation holes 7 reduce the probability of overheating and damage to the first motor 23 and the second motor 32, thus extending the lifespan of the device.

[0040] The operating principle of a land surveying drone in this embodiment is as follows: When staff need to survey the land, they need to start the drone, which causes the wings 12 to operate, thus lifting the drone body 1 into the air, allowing the surveying camera 14 to capture images of the land. The captured images are then uploaded. During this process, if staff need to adjust the angle of the surveying camera 14, they need to activate the adjustment device to adjust the angle of the camera 14, thereby capturing images of a larger area of ​​land and reducing the limitations of the device.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
