It has the advantages of flexibility, efficiency, safety and low cost. Its application areas include urban planning, geographic surveying, environmental protection, agricultural monitoring, etc. UAVs are maneuverable, flexible, efficient, fast, precise and accurate, and can reduce the cost of surveying and mapping operations and expand the scope of surveying and mapping. It has obvious advantages in small areas and areas where flying is difficult.

[0003] A Chinese utility model patent with publication number CN217994806U discloses a UAV surveying and mapping data acquisition device, which relates to the field of UAV surveying and mapping technology, and includes a UAV surveying and mapping body and fixed support legs, wherein the fixed support legs are installed and fixed on both sides of the lower end of the UAV surveying and mapping body, a fixed panel is arranged between the fixed support legs, a gear motor is arranged at the upper end of the fixed panel, and a range gear adjuster is arranged on the outer side of the gear of the gear motor.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the process of surveying and photographing by drone, once the drone fails or an emergency such as "explosion" occurs, the above-mentioned device lacks protection for the photographic device, and the photographic device is easily directly damaged after the drone falls. Not only is the data in the photographic device easily lost, but the cost of repair or replacement is increased. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a photography device for unmanned aerial vehicle surveying and mapping.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a photographic device for unmanned aerial vehicle surveying and mapping, comprising an unmanned aerial vehicle body and a photographic device body arranged at the bottom of the unmanned aerial vehicle body, a mounting frame is fixed at the bottom of the unmanned aerial vehicle body, mounting blocks are fixed to the side walls on both sides of the mounting frame, each of the side walls of the mounting blocks is provided with a mounting groove, each of the side walls of the mounting blocks is installed with a protective component for protecting the photographic device body, each group of the protective components includes a rotating shaft rotatably connected to the inner wall of the mounting groove, a fixed block fixedly sleeved on the rotating shaft, a protective shell fixed to the upper surface of the fixed block, and a torsion spring arranged in the mounting groove, one end of the torsion spring is fixed to the inner wall of the mounting groove, and the other end of the torsion spring is fixed to the side wall of the fixed block, and a limiting component for limiting the protective shell is installed at the bottom of the unmanned aerial vehicle body.

[0007] By adopting the above technical solution, when the drone body fails or an emergency such as "explosion" occurs, the staff releases the limiting effect on the protective shell by controlling the limit assembly. The two protective shells rotate downward under the torsion of the torsion spring, so that the two protective shells cooperate with each other and press tightly. The photographic device body is covered inside the protective shell, which protects the photographic device, reduces the probability of data loss or damage caused by the photographic device body falling, and reduces the cost of repair or replacement.

[0008] Furthermore, the limit assembly includes a mounting plate fixed to the bottom of the drone body, a mounting rod rotatably connected to the side wall of the mounting plate, an L-shaped block fixedly mounted on the mounting rod, and a drive motor fixed to the side wall of the mounting plate, the output shaft of the drive motor passes through the side wall of the mounting plate and is rotatably connected, the end of the output shaft of the drive motor is fixed to the end of the mounting rod, a controller electrically connected to the drive motor is provided at the bottom of the drone body, and a signal receiver electrically connected to the controller is provided at the bottom of the drone body.

[0009] By adopting the above technical solution, when it is necessary to release the limiting effect of the limiting assembly, the signal receiver receives the control signal and transmits it to the controller. The controller controls the drive motor to start and drive the mounting rod to rotate. The L-shaped block rotates with the mounting rod and moves away from the protective shell, so that the protective shell rotates and opens under the torsion of the torsion spring. When there is no need to open the protective shell, the L-shaped block maintains an abutment state with the protective shell, reducing the probability of the protective shell automatically opening and affecting the surveying and mapping.

[0010] Furthermore, two side walls of the protective shell are embedded with strong magnetic blocks, and the two strong magnetic blocks are magnetically attracted to each other.

[0011] By adopting the above technical solution, after the protective shell is opened, two strong magnetic blocks adsorb the two protective shells together, thereby reducing the probability of the protective shell being opened under the action of gravity or external force.

[0012] Furthermore, each side wall of the protective shell is fixed with a rubber pad.

[0013] By adopting the above technical solution, the rubber pad is made of rubber material, and the material is elastic, which reduces the impact on the protective shell and enhances the protective effect on the photographic device body.

[0014] Furthermore, the side wall of the mounting plate is provided with a protective cover for covering the driving motor.

[0015] By adopting the above technical solution, the protective cover protects the drive motor and reduces the probability of damage to the drive motor under the action of external force.

[0016] Furthermore, a gyro sensor electrically connected to the controller is provided at the bottom of the drone body.

[0017] By adopting the above technical solution, when the gyro sensor recognizes that the flight posture of the drone body is abnormal, the controller controls the drive motor to start the limit release to open the protective shell, thereby eliminating the tedious operation of opening the protective shell by remote control, which is conducive to the rapid protection of the photographic device body.

[0018] Furthermore, a plurality of warning lights electrically connected to the controller are provided on the surface of the drone body.

[0019] By adopting the above technical solution, when the limiting effect of the limiting assembly is released by driving the motor and the protective shell is opened, the warning light lights up and flashes, making the drone body more eye-catching and facilitating the staff to quickly find the drone body.

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

[0021] 1. In this application, when the drone body fails or an emergency such as "explosion" occurs, the staff releases the limiting effect on the protective shell by controlling the limiting component, and the two protective shells rotate downward under the torsion of the torsion spring, so that the two protective shells cooperate with each other and press tightly, and the camera body is covered inside the protective shell, which protects the camera body, reduces the probability of data loss or damage caused by the camera body falling, and reduces the cost of repair or replacement;

[0022] 2. In the present application, when the limiting function of the limiting assembly needs to be released, the signal receiver receives the control signal and transmits it to the controller, and the controller controls the drive motor to start and drive the mounting rod to rotate, and the L-shaped block rotates with the mounting rod and moves away from the protective shell, so that the protective shell rotates and opens under the torsion of the torsion spring. When the protective shell does not need to be opened, the L-shaped block remains in contact with the protective shell, reducing the probability of the protective shell automatically opening and affecting the surveying and mapping;

[0023] 3. In this application, after the protective shell is opened, two strong magnetic blocks adsorb the two protective shells together, reducing the probability of the protective shell being opened under the action of gravity or external force. BRIEF DESCRIPTION OF THE DRAWINGS
