Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping instrument fixing, in particular to a surveying and mapping instrument fixing device for aircraft surveying and mapping. Background Art

[0002] Compared with traditional surveying and mapping methods, UAV surveying and mapping is flexible, convenient, efficient, fast, precise, accurate, has low operating costs, and a wide range of applications. Its advantages are more obvious when faced with surveying and mapping areas with small areas and complex terrain, so it has been widely used.

[0003] Application No. CN201811544025.2 shows a surveying and inspection fixed-wing vertical take-off and landing UAV, which is connected to the camera by a connecting mechanism such as a rotating connecting shaft. Therefore, when the speed of the UAV changes, due to the action of inertia, the camera flexibly connected to the mounting block will shake at the moment of acceleration or deceleration. At this time, the camera is no longer horizontal with the horizontal plane, but is in a tilted state. At this time, the picture taken by the camera will shake. In the present invention, when the speed of the UAV changes, due to the action of inertia, the camera has an impact force in a certain direction. At this time, the moving rod hinged to the camera has a tendency to extend into the cylinder, and the moving rod on the other side has a tendency to extend out of the cylinder. However, whether the moving rod has a tendency to extend into the cylinder or the moving rod has a tendency to extend out of the cylinder, it is necessary to overcome the damping force of the flow of the flowable medium. Therefore, when overcoming this process, the effect of the inertia force on the camera has been weakened a lot. At this time, the camera only needs to shake slightly to overcome the effect of the inertia force, further improving the camera's stability and improving the smoothness of picture shooting.

[0004] The existing drone aerial photography and mapping is completed through the camera. The connection method between the existing surveying instrument camera and the drone is mostly fixed connection or bolt connection. It is troublesome to fix or disassemble the surveying camera assembly, and the operation is not convenient. At the same time, there are more dust and impurities in the air when the drone is surveying at high altitude. The dust and impurities will adhere to the camera surface of the surveying instrument, affecting the surveying and mapping effect. Most of the existing cleaning operations use a cleaning rod to move back and forth on the surface of the lens to achieve the cleaning effect. However, since the camera is always in the camera state during the surveying process, when the cleaning rod moves back and forth to clean, the image taken during the surveying and mapping period will have a shadow blocked by the cleaning rod when it moves on the lens surface, affecting the overall shooting continuity and shooting effect. Summary of the invention

[0005] The object of the present invention is to provide a surveying instrument fixing device for aircraft surveying and mapping, so as to solve the problem that the connection method between the existing surveying instrument camera and the drone proposed in the above background technology is mostly fixed connection or bolt connection, which is troublesome and inconvenient to operate when fixing or disassembling the surveying and mapping camera assembly. At the same time, when the drone is surveying at high altitude, there are more dust and impurities in the air, and the dust and impurities will adhere to the camera surface of the surveying instrument, affecting the surveying and mapping shooting effect. Most of the existing cleaning operations use a cleaning rod to move back and forth on the surface of the lens to achieve the cleaning effect. However, since the camera is always in the shooting state during the surveying and mapping process, when the cleaning rod moves back and forth to clean, the image taken during the surveying and mapping period will have a shadow blocked by the cleaning rod when it moves on the lens surface, affecting the overall shooting continuity and shooting effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the arrangement of the gas collecting cylinder 1 and the piston contact rod, when the UAV lands on the ground, the piston contact rod contacts and squeezes the ground, thereby squeezing the internal gas of the gas collecting cylinder 1 into the inside of the gas collecting cylinder 2, so that the piston rod drives the supporting frame to rise steadily under the limit of the limit angle block, thereby driving the surveying and mapping camera assembly fixed by the secondary adsorption of the suction cup on the top of the supporting frame to be lifted and removed synchronously, so that it is convenient for the operator to quickly disassemble and remove the surveying and mapping camera assembly. At the same time, when the UAV takes off, the piston contact rod is separated from the ground, and the tension spring is reset and rebounded, so that the internal gas of the gas collecting cylinder 1 is sucked back into the inside of the gas collecting cylinder 1, so that the lifted supporting frame and the surveying and mapping camera assembly are automatically reset and fixed inside the disc loading box, so that the surveying and mapping camera assembly can be automatically lifted and disassembled and automatically dropped and fixed, and the overall operation is convenient and easy to use;

[0018] 2. Through the arrangement of the disc loading box, the glass ring arranged in close contact and rotation on the inner wall, and the sealing cover, the mapping camera assembly can be isolated and protected. At the same time, when the UAV lands on the ground and the piston contact rod contacts and squeezes the ground, the piston rod will drive the twisted rod to rise synchronously, thereby driving the guide block installed through to rotate, thereby driving the external protective plate to rotate synchronously, so as to isolate and protect the surface of one side of the glass ring exposed at the through hole, avoiding damage caused by touching the exposed surface of the glass ring by the operator during disassembly and maintenance, and playing a certain protective role. At the same time, when the UAV takes off, the twisted rod descends, driving the guide block and the protective plate to reset and rotate, so that one side of the glass ring is exposed again, ensuring the high-altitude shooting effect;

[0019] 3. The output shaft of the driving motor drives the gear to rotate, thereby driving the sealing ring, the gear ring and the glass ring on one side to rotate synchronously, so that the glass ring surface at the shooting end of the surveying and mapping camera assembly rotates and switches continuously, and at the same time, the rotating glass ring surface will be wiped by the wiping cloth belt on one side that is not in the lens, so as to perform the dust cleaning operation. At the same time, during the surveying and mapping shooting and dust cleaning process, the images taken during this period of time will not have the shadow of the cleaning rod moving on the lens surface, so as to ensure the overall shooting continuity and shooting effect. At the same time, when the gear rotates, it will drive the rotating shaft to rotate, thereby driving the externally mounted fitting belt and wiping cloth belt to rotate, so that the contact surface of the wiping cloth belt and the glass ring can be automatically switched, and at the same time, the switched surface of the wiping cloth belt will contact the comb plate on one side, so as to comb up and separate the impurities and dust cleaned on the surface of the wiping cloth belt, automatically clean the surface of the wiping cloth belt, avoid impurities accumulation, increase service life and ensure the cleaning effect;

[0020] 4. When the operating temperature of the surveying and mapping camera assembly inside the disc loading box is too high, the heat expansion airbag inside one side of the copper box body will expand due to the heat, thereby resisting the partition to drive the sealing block to move so that multiple heat dissipation holes on the top of the sealing cover are opened for heat dissipation. At the same time, the movement of the resisting partition will drive the slider to move synchronously, so that the rubber roller on one side of the slider fits the inner wall of one side of the glass ring, so that when the glass ring rotates, it will drive the rubber roller to rotate synchronously, and cooperate with the transmission connection of the sprocket chain transmission assembly to drive the fan blades on the bottom side of the heat dissipation hole to rotate synchronously, thereby improving the heat dissipation efficiency of the heat inside the disc loading box, and the overall heat dissipation effect is good, ensuring the operating stability of the surveying and mapping camera assembly and extending its service life.

When the drone is landing, the camera disassembly and assembly assembly 6 is triggered to operate, thereby The surveying and mapping camera assembly 11 is moved out of the disc loading box 2. When the UAV takes off, the camera disassembly and assembly assembly 6 is triggered to run again, thereby resetting the surveying and mapping camera assembly 11 to the inside of the disc loading box 2, so that the surveying and mapping camera assembly 11 can be automatically lifted and disassembled and automatically dropped and fixed. The overall operation is convenient and easy to use. When the UAV drives the surveying and mapping instrument for high-altitude surveying and mapping, the cleaning assembly 7 can be started to rotate the glass ring 10 to clean the surface of the glass ring 10, thereby ensuring the cleanliness of the surface of the glass ring 10 on the front side of the surveying and mapping camera assembly 11 and ensuring the surveying and mapping shooting effect. At the same time, during the surveying and mapping shooting cleaning process, the images taken during this period of time will not have shadows blocked by the cleaning rod when it moves on the lens surface, thereby ensuring the overall shooting continuity and shooting effect.

[0039] When the UAV takes off, the piston contact rod 602 is separated from the ground, and the tension spring 609 is reset and rebounded, so that the piston contact rod 602 moves downward, thereby sucking the internal gas of the gas collecting cylinder 601 back into the gas collecting cylinder 601, so that the lifted support frame 606 and the surveying and mapping camera assembly 11 are automatically reset and fixed inside the disc loading box 2, so that the surveying and mapping camera assembly 11 can be automatically lifted and disassembled and automatically dropped and fixed, and the overall operation is convenient and easy to use.

[0046] Combination Fig. 9 , Fig.10 and Fig.11 As shown, when the gear 704 rotates, it will drive the rotating shaft 707 to rotate, thereby driving the externally mounted belt 708 and the wiping cloth belt 709 to rotate, so that the surface of the wiping cloth belt 709 in contact with the glass ring 10 can be automatically switched, and at the same time, the switched surface of the wiping cloth belt 709 will contact the comb plate 7011 on one side, thereby combing up and separating the impurities and dust cleaned on the surface of the wiping cloth belt 709, automatically cleaning the surface of the wiping cloth belt 709, avoiding the accumulation of impurities, increasing the service life and ensuring the cleaning effect.

A sealing block 809 is fitted on one side of the bottom end of the heat dissipation hole 801, and one side of the sealing block 809 is fixed to the top side of the partition 807 through a bracket.

[0048] Combination Fig.10 and Fig.12 As shown, when the operating temperature of the surveying and imaging assembly 11 inside the disc loading box 2 is too high, the heat expansion airbag 808 inside one side of the copper box body 802 expands due to the heat, thereby contacting the partition 807 and driving the sealing block 809 to move so that the multiple heat dissipation holes 801 on the top of the sealing cover 5 open to dissipate heat.

[0049] At the same time, the surface temperature of the glass ring 10 located on one side of the through hole 4 in contact with the outside air is relatively low, while the surface temperature of the glass ring 10 located inside the disc loading box 2 is relatively high. Through the continuous rotation of the glass ring 10, the heat generated by the operation of the surveying and imaging component 11 inside the disc loading box 2 can be rotated and absorbed and brought out, and it also has a certain heat dissipation effect.

[0050] In some embodiments, the self-cooling component 8 also includes a rubber roller 804, a fan blade 805 and a sprocket chain transmission assembly 806, the rubber roller 804 is rotatably installed on the side of the slider 803 close to the glass ring 10, and the fan blade 805 is rotatably installed on the side of the slider 803 close to the heat dissipation hole 801, and the sprocket chain transmission assembly 806 is installed in a transmission connection between the fan blade 805 and the rubber roller 804; the self-cooling component 8 also includes a reset spring 8010, and the reset spring 8010 is fixedly connected to the outside of the side of the partition 807 away from the thermal expansion airbag 808, and the other end of the reset spring 8010 is embedded and fixed on the inner wall of one side of the copper box body 802.

[0051] Combination Fig.12As shown, when the abutting partition 807 moves, the slider 803 is driven to move synchronously, so that the rubber roller 804 on one side of the slider 803 fits with the inner wall of one side of the glass ring 10, so that when the glass ring 10 rotates, the rubber roller 804 is driven to rotate synchronously, and the transmission connection of the sprocket chain transmission assembly 806 is cooperated, so that when the rubber roller 804 rotates, the fan blade 805 on the bottom side of the heat dissipation hole 801 is driven to rotate synchronously, thereby improving the heat dissipation efficiency of the internal heat of the disc loading box 2, and the overall heat dissipation effect is good, ensuring the operating stability of the surveying and mapping camera assembly 11 and extending the service life. When the internal temperature of the disc loading box 2 drops, the thermal expansion airbag 808 shrinks and cooperates with the reset spring 8010 to resist and reset, so that the sealing block 809 moves to close the multiple heat dissipation holes 801 on the top of the sealing cover 5, so as to prevent impurities or rainwater from entering the disc loading box 2 through the heat dissipation holes 801 when the internal temperature is not high, causing short circuit damage to internal components.
