Description

Technical Field

[0001] This invention relates to the field of engineering cost estimation, and in particular to an aerial photography aircraft for measuring building area. Background Technology

[0002] Unmanned aerial surveying is a powerful supplement to traditional aerial photogrammetry, and it has broad prospects, especially in basic surveying and mapping, land resource investigation and monitoring, dynamic monitoring of land use, digital city construction, and emergency disaster relief surveying and mapping data acquisition.

[0003] Traditional aerial photography drones generally fall into two categories: those with built-in cameras and those requiring manual camera mounting. Because surveying requires recording various factors, drones equipped with different types of cameras to meet specific needs are more popular.

[0004] Traditional cameras require different mounting brackets depending on their shape and size during installation. The process of disassembling and assembling these brackets is quite cumbersome, making camera replacement inconvenient and requiring improvement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an aerial photography aircraft for measuring building area, which offers the advantage of convenient camera replacement.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an aerial photography aircraft for measuring building area, comprising:

[0007] Drones are flown by remote control.

[0008] The suspension is located below the drone;

[0009] A pair of grippers are horizontally slidably disposed on the lower end face of the suspension and are used to grip both sides of the camera;

[0010] A pair of springs are disposed on the suspension and are used to drive the pair of grippers to move closer to each other;

[0011] A hook is provided on the inside of the gripper and is used to hook the lower end face of the camera.

[0012] By adopting the above technical solution, when it is necessary to fix a camera, mobile phone, or webcam, a pair of grippers are pushed apart, and then the camera equipment is placed between the grippers. The grippers hold the sides of the camera equipment, while the hooks secure the bottom surface of the camera equipment, thus achieving clamping and fixing. Therefore, by setting up a clamping fixing mechanism, different types of camera equipment can be clamped and fixed, enabling quick replacement of camera equipment, meeting different usage needs, and improving practicality.

[0013] In a preferred embodiment, the present invention can be further configured such that: the gripper includes a slide rail and a slide plate, the slide rail is vertically disposed on the suspension, the slide plate is vertically slidably connected to the slide rail, the hook is located on the slide plate, and a locking mechanism for fixing the slide plate is provided on the slide rail.

[0014] By adopting the above technical solution, when fixing camera equipment of different thicknesses, the vertical sliding of the slide plate is controlled, the height of the hook is adjusted, and the sliding plate is fixed by the locking mechanism, so as to achieve stable fixing of camera equipment of different thicknesses.

[0015] In a preferred embodiment, the present invention can be further configured such that: the locking mechanism includes a locking plate, a torsion spring, and a locking hook; the locking plate is rotatably connected to the side wall of the slide rail in a bent shape; the torsion spring is located at the rotatable connection position of the locking plate; the locking hook is disposed at the lower end of the locking plate and is used to penetrate the slide rail; and the outer wall of the slide plate is provided with a row of locking grooves for the locking hook to be inserted.

[0016] By adopting the above technical solution, when adjusting the extension / retraction of the skateboard, pressing the locking plate flips it, causing the locking hook to disengage from the locking groove, thus releasing the skateboard from its lock. When the skateboard is in the correct position, releasing the locking plate causes it to flip in the opposite direction under the action of the torsion spring, and the locking hook engages with the locking groove, locking the skateboard in place. Therefore, by setting up a simple and easy-to-operate locking mechanism, the extension / retraction of the skateboard can be quickly adjusted.

[0017] In a preferred embodiment, the present invention may be further configured such that the upper end of the locking plate is bent outward to form a pressing portion.

[0018] By adopting the above technical solution and setting a pressing part, the pressing and flipping process of the locking plate becomes easier and more convenient.

[0019] In a preferred embodiment, the present invention may be further configured such that a silicone pad is provided on the inner side of the connection position between the skateboard and the hook.

[0020] By adopting the above technical solution and setting silicone pads, the corners of the camera equipment can be protected to prevent pressure damage.

[0021] In a preferred embodiment, the present invention may be further configured such that a suction cup is provided on the lower end face of the suspension.

[0022] By adopting the above technical solution, suction cups are used to attach and fix the camera equipment, thereby increasing the stability of the camera equipment during operation.

[0023] In a preferred embodiment, the present invention may be further configured such that the suction cup is provided with a flat-nozzle-shaped exhaust pipe.

[0024] By adopting the above technical solution, when the suction cup is working, the gas inside the suction cup can be discharged through the exhaust pipe. At the same time, after discharge, the openings of the exhaust pipes are sealed together, creating a vacuum inside the suction cup. When it is necessary to disassemble the camera equipment, the exhaust pipe is squeezed to open it, ensuring communication between the inside and outside of the suction cup, thus facilitating the removal and disassembly of the camera equipment.

[0025] In a preferred embodiment, the present invention can be further configured as follows: the drone includes a base, four arms, four propellers, and a support frame. The arms are arranged around the base, the propellers are rotatably mounted on the arms, the support frame is arranged on the lower end face of the base, a receiving groove is provided between the side walls of the base and the arms, an airbag is embedded in the receiving groove, a plastic buckle for holding the airbag is provided in the receiving groove, and an air inlet pipe with an opening facing downward and communicating with the airbag is provided on the lower end face of the base.

[0026] By adopting the above technical solution, when the drone descends rapidly or crashes, air will enter the airbag along the air intake pipe as the drone descends, causing the airbag to detach from the plastic buckle and inflate into a fan shape. At this time, multiple airbags, together with the base, form a circular parachute to increase the contact area with the air, slow down the drone's descent speed, and allow the drone to land slowly or fall to the ground, which can reduce damage to the drone and reduce harm to people.

[0027] In a preferred embodiment, the present invention can be further configured such that: a one-way valve is provided on the lower end face of the base, and the upper end of the air inlet pipe is ball-connected to the one-way valve.

[0028] By adopting the above technical solution, when the drone lands or crashes, air enters the airbag. At this time, the one-way valve prevents the air from escaping, keeping the airbag in an inflated state and ensuring a stable landing. Upon landing, the air intake pipe and one-way valve can be disconnected to expel the air from the airbag and allow it to retract. Simultaneously, because the air intake pipe is ball-connected to the one-way valve, it automatically rotates regardless of whether the drone falls flat or at an angle, aligning its lower end with the direction of movement to facilitate air entry into the airbag. Furthermore, with any airbag inflation, the drone's direction is automatically adjusted, ensuring a flat descent and guaranteeing the drone's support frame contacts the ground, reducing damage to the drone and minimizing injury to people.

[0029] In a preferred embodiment, the present invention can be further configured such that the lower end of the air inlet pipe is flared.

[0030] By adopting the above technical solution and setting up an flared air inlet pipe, air can easily enter the air inlet pipe, enabling the airbag to expand rapidly, reducing the drone's fall speed immediately, and giving ground personnel sufficient preparation time.

[0031] In summary, the present invention has the following beneficial effects:

[0032] 1. By setting up a clamping and fixing mechanism, different types of camera equipment can be clamped and fixed, enabling quick replacement of camera equipment, meeting different usage needs, and improving practicality;

[0033] 2. By setting adjustable grippers, the height of the hook can be adjusted, and a locking mechanism can be used to fix the slide plate, thus achieving stable fixation of camera equipment of different thicknesses;

[0034] 3. By using suction cups to attach and fix the camera equipment, the stability of the camera equipment during operation can be increased. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 , Figure 2 As shown, a drone for measuring building area includes a drone 1, a suspension 2, a pair of grippers 3, a pair of springs 4, and a hook 5.

[0043] like Figure 2 As shown, the drone 1 is remotely controlled to fly, and the suspension 2 is located below the drone 1. A pair of grippers 3 are horizontally slidably mounted on the lower end face of the suspension 2 and are used to grip both sides of the camera. A pair of springs 4 are mounted on the suspension 2 and are used to drive the pair of grippers 3 to move closer together. Hooks 5 are located on the inner side of the grippers 3 and are used to hook the lower end face of the camera.

[0044] When it is necessary to fix a camera, mobile phone or webcam, push a pair of clamps 3 away from each other, then place the camera equipment between the pair of clamps 3, use the clamps 3 to hold the two sides of the camera equipment, and at the same time use the hooks 5 to hook the lower end of the camera equipment to achieve the clamping and fixing of the camera equipment.

[0045] Therefore, by setting up a clamping and fixing mechanism, different types of camera equipment can be clamped and fixed, enabling quick replacement of camera equipment, meeting different usage needs, and improving practicality.

[0046] like Figure 2 As shown, a suction cup 6 is provided on the lower end face of the suspension 2 to achieve adsorption and fixation of the camera equipment, increasing the stability of the camera equipment during operation. The suction cup 6 is equipped with a flat-nozzle-shaped exhaust pipe 61. When the suction cup 6 is working, the gas inside the suction cup 6 can be discharged through the exhaust pipe 61. Simultaneously, after discharge, the opening of the exhaust pipe 61 closes together, creating a vacuum inside the suction cup 6. When it is necessary to disassemble the camera equipment, the exhaust pipe 61 is squeezed to open it, ensuring communication between the inside and outside of the suction cup 6, thus facilitating the removal and detachment of the camera equipment.

[0047] like Figure 2 As shown, the gripper 3 includes a slide rail 31 and a slide plate 32. The slide rail 31 is vertically mounted on the suspension 2, and the slide plate 32 is vertically slidably connected to the slide rail 31. The hook 5 is located on the slide plate 32, and a silicone pad 33 is provided on the inner side of the connection position between the slide plate 32 and the hook 5 to protect the corners of the camera equipment and prevent damage from pressure.

[0048] like Figure 2 As shown, a locking mechanism 7 for fixing the slide plate 32 is provided on the slide rail 31. The locking mechanism 7 includes a locking plate 71, a torsion spring 72, and a locking hook 73. The locking plate 71 is rotatably connected to the side wall of the slide rail 31 in a bent shape, and the upper end of the locking plate 71 is bent outward to form a pressing part 74.

[0049] like Figure 2 As shown, the torsion spring 72 is located at the rotatable connection position of the locking plate 71, the locking hook 73 is located at the lower end of the locking plate 71 and is used to pass through the slide rail 31, and the outer wall of the slide plate 32 is provided with a row of locking grooves 75 for the locking hook 73 to be inserted.

[0050] When fixing camera equipment of different thicknesses, press the locking plate 71 to flip it, causing the locking hook 73 to disengage from the locking groove 75, thereby releasing the locking of the slide plate 32. Then, the slide plate 32 can be controlled to slide vertically, adjusting the height of the latch 5.

[0051] When the hook 5 and the slide plate 32 are in the correct positions, the locking plate 71 is released. At this time, under the action of the torsion spring 72, the locking plate 71 is flipped in the opposite direction, and the locking hook 73 hooks the locking groove 75, thereby locking the slide plate 32. At the same time, the camera equipment of different thicknesses can be securely fixed.

[0052] like Figure 3 , Figure 4 , Figure 5 As shown, the UAV 1 includes a base 11, four booms 12, four propellers 13, and a support frame 14. The base 11 is square in shape, the four booms 12 are arranged around the base 11, the four propellers 13 are rotatably mounted on the booms 12, and the support frame 14 is arranged on the lower end face of the base 11.

[0053] like Figure 3 , Figure 4 , Figure 5 As shown, a receiving groove 15 is provided between the side walls of the base 11 and the arm 12. An airbag 16 is embedded in the receiving groove 15. A plastic buckle 17 is provided in the receiving groove 15 to hold the airbag 16. When the airbag 16 is inflated, it bursts open the plastic buckle 17 and unfolds outward in a fan shape.

[0054] like Figure 3 , Figure 4 , Figure 5 As shown, a one-way valve 18 is provided on the lower end face of the base 11, and an air inlet pipe 19 with an opening facing downward and connected to the one-way valve 18 is provided below the base 11. The upper end of the air inlet pipe 19 is ball-connected to the one-way valve 18, and the lower end is flared to facilitate the entry of air into the air inlet pipe 19, so as to realize the rapid expansion of the airbag 16, reduce the fall speed of the UAV 1 as soon as possible, and give the ground personnel sufficient preparation time.

[0055] When the drone 1 descends rapidly or crashes, as the drone 1 descends, air will enter the airbag 16 along the air intake duct 19, causing the airbag 16 to detach from the plastic buckle 17 and inflate to form a fan shape. At this time, multiple airbags 16, together with the base 11, form a circular parachute to increase the contact area with the air, slow down the descent speed of the drone 1, and allow the drone 1 to land slowly or fall to the ground, which can reduce the damage to the drone 1 and reduce the harm to people.

[0056] When the drone 1 lands or crashes, air enters the airbag 16. At this time, under the restriction of the one-way valve 18, the air in the airbag 16 is prevented from being discharged, so that the airbag 16 is always in an inflated state, ensuring the stable landing of the drone 1.

[0057] Upon landing, the air intake pipe 19 and the one-way valve 18 can be disconnected to expel air from the airbag 16 and allow the airbag 16 to be stored. At the same time, since the air intake pipe 19 is ball-connected to the one-way valve 18, the air intake pipe 19 can automatically rotate, so that the lower end faces the direction of movement, regardless of whether the drone 1 falls flat or tilted, which helps air enter the airbag 16.

[0058] Furthermore, as any airbag 16 inflates, the direction of the drone 1 can be automatically adjusted, ensuring that the drone 1 falls flat and that the support frame 14 of the drone 1 contacts the ground, thereby reducing damage to the drone 1 and minimizing harm to people.

[0059] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
