Description

Technical Field

[0001] The present application relates to the technical field of surveying and mapping UAVs, and in particular to a multi-lens surveying and mapping UAV. Background Art

[0002] Compared with traditional surveying and mapping methods and technologies, UAV aerial surveying is a more innovative surveying and mapping technology. UAV aerial surveying is an aerial surveying method that uses aerial drones to collect data and conduct investigation and analysis. It is a technical means to achieve rapid surveying and mapping using aerial image data and auxiliary technologies equipped by drones. It is also called aerial survey and analysis.

[0003] With respect to the above-mentioned related technologies, the inventors believe that in the traditional technology, when a UAV is conducting surveying and mapping, the UAV needs to be equipped with a surveying lens. When the UAV is flying, the surveying lens can survey the site that needs to be surveyed below the UAV. However, the number of surveying lenses of existing surveying and mapping UAVs is fixed. Since the site that the UAV needs to survey is not fixed, the surveying range of the conventional number of surveying lenses is limited and there are defects. Therefore, a multi-lens surveying and mapping UAV is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that in traditional technology, when drones are surveying and mapping, the drones need to be equipped with surveying lenses. When the drone is flying, the surveying lenses can survey the site that needs to be surveyed below the drone. However, the number of surveying lenses of existing surveying drones is fixed. Since the site that needs to be surveyed by the drone is not fixed, the surveying range of the conventional number of surveying lenses is limited. This application provides a multi-lens surveying drone.

[0006] The multi-lens mapping drone provided in this application adopts the following technical solution:

[0007] A multi-lens mapping drone comprises a drone body, a lens base and a lens protection assembly, wherein four rectangular grooves are provided at equal intervals and in a circumferential shape at the bottom of the drone body, a servo motor is fixedly connected to the inner wall of one end of the rectangular groove, an output end of the servo motor is fixedly connected to a lead screw via a coupling, an external thread of the lead screw is connected to a slider, a transmission rod is hinged to the top of the slider, an end of the transmission rod away from the slider is hinged to the bottom of the lens base, a lens is installed at the bottom of the lens base, the servo motor is started, the servo motor drives the lead screw to rotate, the rotation of the lead screw drives the slider outside the lead screw to move outside the lead screw, the slider slides outside the lead screw, and under the action of the transmission rod, the lens base rotates around the hinged edge, thereby realizing the angle adjustment of the lens base and the lens, thereby increasing the mapping range of the lens.

[0008] Preferably, the lens protection assembly includes an annular groove formed at the bottom of the drone body and located at the periphery of the lens base, an annular protective shell is movably provided inside the annular groove, a connecting ear is fixedly connected to the edge of one side of the bottom of the annular protective shell, a hydraulic cylinder is fixedly connected to the edge of one side of the drone body, and the output end of the hydraulic cylinder is fixedly connected to the connecting ear. When the drone does not need to perform surveying and mapping work, the hydraulic cylinder is started, and the hydraulic cylinder starts to drive the connecting ear and the annular protective shell to detach from the inside of the annular groove, thereby enclosing the four lenses, thereby effectively protecting the lenses.

[0009] Preferably, damping rods are fixedly connected to the four corners of the bottom of the drone body, and the bottom of the damping rods is fixedly connected to a support pad. When the drone body lands on the ground, the support pad will first contact the ground. At this time, the damping rod is compressed, thereby effectively buffering the impact energy of the drone body when it lands on the ground, thereby achieving effective protection of the drone body.

[0010] Preferably, at least one outer side wall of the slider is tightly fitted with the inner wall of the rectangular groove, thereby increasing the stability of the slider when moving inside the rectangular groove.

[0011] Preferably, the lens base is hinged to the bottom of the drone body, and the lens base can rotate around the drone body.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By starting the servo motors inside each rectangular slot, the lead screw will rotate under the action of the servo motor, and the rotation of the lead screw will drive the slider outside it to move outside the lead screw. Under the action of the transmission rod, multiple lens bases and lenses will rotate around the hinged edge; compared with the prior art, the present application can realize the angle adjustment of four lens bases and lenses, thereby greatly increasing the surveying and mapping range of the drone.

[0014] 2. When the UAV does not need to perform surveying and mapping work, the hydraulic cylinder is started, and the hydraulic cylinder starts to drive the connecting ear and the annular protective shell to separate from the inside of the annular groove, enclosing the four lenses, thereby effectively protecting the lenses.

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application embodiment discloses a multi-lens mapping drone, referring to Figure 1 , Figure 4 and Figure 5, including a drone body 1, a lens base 2 and a lens protection component. The bottom of the drone body 1 is provided with four rectangular grooves 3 at equal intervals and in a circumferential shape. A servo motor 4 is fixedly connected to the inner wall of one end of the rectangular groove 3. The output end of the servo motor 4 is fixedly connected to a screw rod 5 through a coupling. The external thread of the screw rod 5 is connected to a slider 6. The top of the slider 6 is hinged with a transmission rod 7. The end of the transmission rod 7 away from the slider 6 is hinged to the bottom of the lens base 2. A lens 8 is installed at the bottom of the lens base 2. By starting the servo motor 4, the servo motor 4 works to drive the screw rod 5 to rotate. The rotation of the screw rod 5 will drive the slider 6 outside it to move outside the screw rod 5. The slider 6 slides outside the screw rod 5. Under the action of the transmission rod 7, the lens base 2 will rotate around the hinged edge, so that the angle adjustment of the lens base 2 and the lens 8 can be achieved, thereby increasing the mapping range of the lens 8.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The lens protection assembly includes an annular groove 9 which is opened at the bottom of the drone body 1 and located at the periphery of the lens base 2. An annular protective shell 10 is movably arranged inside the annular groove 9. A connecting ear 11 is fixedly connected to the edge of one side of the bottom of the annular protective shell 10. A hydraulic cylinder 12 is fixedly connected to the edge of one side of the drone body 1. The output end of the hydraulic cylinder 12 is fixedly connected to the connecting ear 11. When the drone does not need to perform surveying and mapping work, by starting the hydraulic cylinder 12, the hydraulic cylinder 12 starts to drive the connecting ear 11 and the annular protective shell 10 to separate from the inside of the annular groove 9, and the four lenses 8 are enclosed, thereby effectively protecting the lenses 8.

[0024] Reference Figure 2 and Figure 4 The four corners at the bottom of the drone body 1 are fixedly connected with damping rods 13, and the bottom of the damping rods 13 is fixedly connected with support pads 14. When the drone body 1 lands on the ground, the support pads 14 will first contact the ground. At this time, the damping rods 13 are compressed, so that the impact energy of the drone body 1 when it lands on the ground can be effectively buffered, thereby achieving effective protection for the drone body 1.

[0025] Reference Figure 5 At least one outer wall of the slider 6 is tightly fitted with the inner wall of the rectangular groove 3, thereby increasing the stability of the slider 6 when moving inside the rectangular groove 3.

[0026] Reference Figure 4 and Figure 5 The lens base 2 is hinged to the bottom of the drone body 1 , and the lens base 2 can rotate around the drone body 1 .

[0027] The implementation principle of a multi-lens mapping drone in the embodiment of the present application is as follows: by starting the servo motor 4, which is preferably of the HBS57 type, the servo motor 4 drives the screw 5 to rotate, and the rotation of the screw 5 drives the slider 6 outside it to move outside the screw 5, and the slider 6 slides outside the screw 5. Under the action of the transmission rod 7, the lens base 2 will rotate around the hinged edge, so that the angle adjustment of the lens base 2 and the lens 8 can be achieved, and the mapping range of the four lenses 8 is increased. When the drone does not need to perform mapping work, by starting the hydraulic cylinder 12, which is preferably of the TN16-20 type, the hydraulic cylinder 12 is started to drive the connecting ear 11 and the annular protective shell 10 to disengage from the inside of the annular groove 9, and the four lenses 8 are enclosed, thereby effectively protecting the lenses 8. When the drone body 1 lands on the ground, the support pad 14 will first contact the ground. At this time, the damping rod 13 is compressed, so that the impact energy of the drone body 1 when it lands on the ground can be effectively buffered, thereby achieving effective protection of the drone body 1.
