Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to a measuring head adjustment device for a highway aerial survey unmanned aerial vehicle. Background Art

[0002] With the continuous acceleration of urbanization, the number of motor vehicles has continued to increase dramatically, and the urban road network has continued to extend. However, while these urban traffic networks bring convenience to people's lives, the situation of many cars and roads has also buried huge hidden dangers for traffic safety, and has posed more arduous challenges to traffic managers. However, there are many loopholes and blind spots in traditional traffic management methods, the defects and disadvantages of the original infrastructure have been continuously exposed, and the technological level of traffic management is stretched. Mobility, urgency, and suddenness are the characteristics of police work, which cannot be met by traditional traffic management methods such as traffic police road patrols and fixed-point camera monitoring. Drones have the characteristics of rapid action, comprehensive information collection, and high controllability, which can meet the real-time data and information needs of the traffic management field. Especially in the field of traffic law enforcement in complex environments, drones provide a new solution for traffic management, which can greatly expand the detectable field in high-risk environments and reduce the harm of dangerous law enforcement environments to the life and property safety of traffic management personnel. For traffic management departments, the comprehensive use of intelligent traffic equipment such as drones, based on the use of existing transportation infrastructure, is of great significance in improving the utilization rate of transportation infrastructure and speeding up the handling of accidents. Fully applying advanced scientific and technological technologies to traffic management has achieved the long-term development goal of "using technology to increase police force" to a certain extent.

[0003] A Chinese patent document with authorization number CN111268131B discloses a drone inspection device, which belongs to the field of equipment inspection technology and includes a drone body, support columns, protective curtains, and protective doors: a slide rail is provided on the drone body, and a camera is slidably arranged on the slide rail; there are four support columns, and the four support columns are symmetrical in pairs and arranged around the slide rail. One end of the support column is connected to the drone body, and the other end is connected to the bottom plate. A vertical slide groove is provided on the support column; there are three protective curtains, and the protective curtains are arranged between two support columns and can slide along the vertical slide grooves of the support columns on both sides thereof; there are two protective doors, and the two protective doors are respectively arranged on two adjacent support columns and opposite to the lens of the camera. The two protective doors can move toward each other and close, and the protective doors and protective curtains protect the camera by closing.

[0004] After the drone inspection is completed, the staff will retract the drone into the hangar used to carry the drone, and then store the drone to protect it. During the use of the above-mentioned drone inspection equipment, when the drone is retracted into the hangar carrying the drone after the inspection, the drone will be lowered to the apron surface of the hangar. Since the legs of the drone are in a fixed position, when the camera equipment is flipped left and right for aerial survey, at certain angles, the legs will directly enter the shooting screen, resulting in part of the screen being blocked, affecting the integrity of the shooting content. For example, when shooting large areas of terrain, buildings and other scenes, the originally complete landscape may be missing due to the obstruction of the legs, and comprehensive and accurate information cannot be obtained.

[0038] The following will refer to the attached Figures 1 to 7 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0039] As attached Figure 1-Figure 7 As shown, a road aerial survey UAV measuring head adjustment device comprises:

[0040] The drone body 10 has a base 11 fixed at the bottom thereof, the base 11 having an opening extending from front to back, a shooting assembly 20 and a supporting assembly 30 installed at the bottom of the base 11, the shooting assembly 20 is used for aerial surveying of roads, and the supporting assembly 30 is used for supporting the drone body 10 when it lands on the ground.

[0041] The shooting assembly 20 includes a mounting frame 21 disposed on the lower side of the base 11. In the present embodiment, the mounting frame 21 is in an inverted U shape. A shooting member 22 is disposed inside the mounting frame 21. First rotating shafts 23 are mounted on both sides of the shooting member 22, and the ends of the two first rotating shafts 23 away from the shooting member 22 are rotatably connected to the inner wall of the mounting frame 21 for supporting the shooting member 22. A first driving source 24 is mounted on one side of the mounting frame 21, and the output end of the first driving source 24 is fixed to one end of the corresponding first rotating shaft 23. The output end of the first driving source 24 drives the shooting member 22 to rotate through the first rotating shaft 23, thereby adjusting the angle at which the shooting member 22 is flipped longitudinally for shooting. In the present embodiment, the first driving source 24 is a motor.

[0042] A support plate 25 is provided on the top of the mounting frame 21. A limit shaft is fixed on the top of the mounting frame 21. The top of the limit shaft is rotatably connected to the bottom of the support plate 25. A second driving source 26 is installed on the top of the support plate 25, and the output end of the second driving source 26 is fixed on the top of the mounting frame 21. The second driving source 26 is used to drive the shooting member 22 to flip horizontally, so as to adjust the shooting angle of the shooting member 22. In this embodiment, the second driving source 26 is also a motor. A support frame 27 is fixed on the top of the mounting frame 21. In this embodiment, the support frame 27 is also an inverted U-shape. A cylinder 28 is installed on the inner wall of the base 11, and the piston rod end of the cylinder 28 is fixed on the top of the support frame 27 for adjusting the height of the shooting member 22.

[0043] The support assembly 30 includes two support members 31 symmetrically arranged at the bottom of the base 11. The support member 31 is composed of a concave block and a bottom shaft. The concave cavity of the concave block faces downward, and both ends of the bottom shaft are rotatably connected to the inner wall of the concave block.

[0044] The top of each support member 31 is fixedly connected to two lower support plates 32, and the outer parts of the two lower support plates 32 are sleeved with upper support plates 33, and the inner part of the upper support plate 33 has a accommodating cavity for accommodating the lower support plates 32, and each lower support plate 32 is slidably connected in the accommodating cavity of the corresponding upper support plate 33, and the top of every two adjacent upper support plates 33 is fixed with a second rotating shaft 34, which is used to drive the support member 31 to rotate, thereby providing a shooting field of view for the shooting member 22, and side panels 35 are installed on both sides of the base 11, each side panel member 35 corresponds to a second rotating shaft 34, and each side panel member 35 is composed of two side panels, and the two side panels are symmetrical with the corresponding second rotating shaft 34 as the center, and both ends of each second rotating shaft 34 are rotatably connected to the side walls of the corresponding side panel.

[0045] An adjusting assembly 40 is disposed on the base 11 for adjusting the angles of the supporting member 31 , the lower supporting plate 32 and the upper supporting plate 33 , so that the shooting member 22 will not be affected when flipping horizontally for shooting.

[0046] The adjusting assembly 40 includes two supporting shafts 41 symmetrically fixed on the supporting disk 25, and two receiving holes 42 symmetrically matched with the supporting shafts 41 are opened on the mounting frame 21, and each receiving hole 42 corresponds to a supporting shaft 41, and the supporting shaft 41 is slidably connected inside the corresponding receiving hole 42, a connecting plate 43 is fixed to the top of each supporting shaft 41, a first tooth plate 44 is fixed to the bottom of each connecting plate 43, a first tooth ring 45 is fixed to the outer wall of each second rotating shaft 34, and each first tooth ring 45 corresponds to a first tooth plate 44, and the first tooth ring 45 is meshed with the first tooth plate 44, when the supporting shaft 41 moves down on the inner wall of the receiving hole 42, the cooperation between the first tooth plate 44 and the first tooth ring 45 can drive the second rotating shaft 34 to rotate and adjust the angle.

[0047] A sleeve 46 is provided on one side of each lower support plate 32, and a limiting hole 47 matched with the sleeve 46 is opened on one side of each lower support plate 32, and the outer surface of the sleeve 46 is fixed on the inner wall of the limiting hole 47, and the diameter of the limiting hole 47 is greater than the diameter of the sleeve 46. Two guide rails 48 are fixed to the outer walls of both sides of the base 11, and each guide rail 48 corresponds to a lower support plate 32, and the sleeve 46 is slidably connected to the inside of the guide rail 48. When the sleeve 46 slides along the track of the guide rail 48, it can drive the lower support plate 32 to slide inside the upper support plate 33.

[0048] Since the shooting piece 22 is a shooting device, and the shooting piece 22 and the drone body 10 are both existing technologies, they are not described again. When in use, the shooting piece 22 is turned on for shooting, and the drone body 10 can be controlled to take off through the ground control system, and the cylinder 28 drives the support frame 27 to move down in height. During the downward movement of the support frame 27, the support shaft 41 simultaneously moves down inside the accommodating hole 42, and the connecting plate 43 also drives the first tooth plate 44 to move down. Since the first tooth plate 44 is meshed and connected with the first gear ring 45, the second rotating shaft 34 rotates from the inside of the base 11 to the outside thereof, and the two second rotating shafts 34 rotate in opposite directions.

[0049] In the rotating state, the second shaft 34 drives the lower support plate 32 to rotate around the axial direction of the second shaft 34 through the upper support plate 33, and the lower support plate 32 synchronously drives the support member 31 to rotate. At this time, the two support members 31 are in an unfolded state away from the shooting member 22, and the upper support plate 33 drives the lower support plate 32 to unfold. At the same time, the sleeve 46 slides inside the guide rail 48, and the sleeve 46 slides from the bottom end of the guide rail 48 to the top end thereof. Since the guide rail 48 is arc-shaped, the bottom end of the guide rail 48 is away from the axis of the second shaft 34, and the top end of the guide rail 48 is close to the axis of the second shaft 34, and the upper support plate 33 rotates around the axis of the second shaft 34. When the guide rail 48 is moved, the sleeve 46 slides from the bottom end to the top end thereof, and at this time, the sleeve 46 drives the connected lower support plate 32 to slide inside the corresponding upper support plate 33, and the lower support plate 32 drives the side plate 35 to slide toward the base 11. After the cylinder 28 drives the support frame 27 to move down to the extreme position, the sleeve 46 is located at the top end of the guide rail 48, thereby preventing the second driving source 26 from driving the shooting member 22 to flip horizontally for aerial survey through the first rotating shaft 23, and the field of view is blocked by the support member 31, the lower support plate 32 and the upper support plate 33. The first driving source 24 can drive the shooting member 22 to flip vertically for aerial survey.

[0050] After the aerial survey is completed, the first driving source 24 and the second driving source 26 both drive the shooting member 22 to return to the initial position, and then the piston rod end of the cylinder 28 drives the support frame 27 to move upward, and the first gear plate 44 drives the second rotating shaft 34 to rotate through the first gear ring 45, so that the support member 31, the lower support plate 32 and the upper support plate 33 are retracted, and the sleeve 46 slides along the top of the guide rail 48 to its bottom end again. When the piston rod end of the cylinder 28 drives the support frame 27 to move up to the extreme position, the sleeve 46 slides from the top of the guide rail 48 to its bottom end, and then the user uses the control system to land the drone body 10 to the apron, and the support member 31 rests on the apron surface.

[0051] The first driving source 24 provided on the mounting frame 21 can drive the mounting frame 21 to flip longitudinally, so that the shooting component 22 can flip up and down for aerial survey. The second driving source 26 provided on the supporting plate 25 can drive the mounting frame 21 to flip transversely, so that the shooting component 22 can flip left and right for aerial survey.

[0052] The cylinder 28 provided on the base 11 can drive the support member 31 to move down in height, thereby expanding the shooting angle of the shooting member 22. During the downward movement of the support frame 27, the support shaft 41 simultaneously moves down inside the accommodating hole 42, and the first tooth plate 44 cooperates with the first tooth ring 45 to drive the second rotating shaft 34 to rotate, and the second rotating shaft 34 drives the connected upper support plate 33 to unfold, and the upper support plate 33 drives the lower support plate 32 and the support member 31 away from the shooting member 22, and the sleeve 46 slides along the track of the guide rail 48, so that the support member 31 can slide toward the installation frame 21, thereby avoiding the loss of field of view when the shooting member 22 is flipped over for shooting, resulting in incomplete shooting.

[0053] Embodiment 2

[0054] When the drone body 10 lands, the bottom shaft of the support member 31 will contact the ground, thereby stabilizing the drone body 10 on the ground. When dirt is attached to the bottom shaft of the support member 31, the contact point between the bottom shaft of the support member 31 and the ground will change, and the originally horizontal support surface will become uneven. When the drone body 10 lands, the center of gravity cannot be evenly distributed on the bottom shaft of the support member 31, resulting in uneven force on a certain bottom shaft and failure to provide sufficient supporting force, thereby causing the drone body 10 to tilt. As the tilt angle increases, the drone body 10 loses balance and eventually falls. In view of this, improvements are made to the first embodiment.

[0055] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a cleaning assembly 50 is provided on the base 11 for cleaning dirt attached to the bottom shaft, thereby maintaining the stability of the drone body 10 when it lands.

[0056] The cleaning assembly 50 includes two scraping strips 51 symmetrically fixed at the bottom of the recess, and the bottom shaft is located between the two corresponding scraping strips 51, which is used to clean the surface of the bottom shaft. A second gear ring 52 is installed on the bottom shaft, and the inner wall of the lower support plate 32 is slidably connected to a second gear plate 53, and the second gear plate 53 is meshingly connected to the second gear ring 52.

[0057] A top plate 54 is fixed to the top of the second tooth plate 53, an end plate 55 is fixed to the inner wall of the lower support plate 32, and a return spring 56 is fixed between the top of the end plate 55 and the bottom of the top plate 54 for supporting the top plate 54 so as to facilitate the return of the top plate 54.

[0058] The inner wall of each sleeve 46 is rotatably connected to a third rotating shaft 57, and one end of the third rotating shaft 57 is rotatably connected to the inner wall of the corresponding lower support plate 32, and a linkage member 58 is fixed to the outer wall of one end of the third rotating shaft 57 located inside the lower support plate 32. In the present embodiment, the linkage member 58 is an arc-shaped block, and a third gear ring 59 is fixed to the outer wall of the third rotating shaft 57, and a linkage rack 510 is fixed to the inner wall of the guide rail 48, and the third gear ring 59 is meshedly connected with the linkage rack 510.

[0059] When the second rotating shaft 34 slides along the track of the guide rail 48, the third gear ring 59 cooperates with the linkage rack 510 to make the third rotating shaft 57 rotate inside the sleeve 46. When the linkage member 58 of the third rotating shaft 57 squeezes the top plate 54, the top plate 54 will move downward, and the second gear ring 52 cooperates with the second tooth plate 53 to drive the bottom shaft to rotate, and the scraper 51 will scrape off the dirt attached to the surface of the bottom shaft, thereby cleaning the surface of the bottom shaft. As the third rotating shaft 57 rotates, when the linkage member 58 releases the restriction on the top plate 54, the top plate 54 is reset by the reset spring 56, and the second gear ring 52 cooperates with the second tooth plate 53 to rotate the bottom shaft again.

[0060] Through the rotation of the third rotating shaft 57, the linkage 58 drives the top plate 54 to move downward, and the second gear ring 52 cooperates with the second gear plate 53 to drive the bottom shaft to rotate, and the scraper 51 can clean the surface of the bottom shaft, thereby preventing the dirt attached to the surface of the bottom shaft from causing the drone body 10 to land and tilt or even fall down.

[0061] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
