TECHNICAL FIELD
[0001] The application belongs to the technical field of land consolidation, and particularly relates to an image collection device for land consolidation engineering. BACKGROUND
[0002] Land consolidation refers to the activity of improving the efficiency of land use by consolidating low-efficiency, unreasonable, and unused land as well as land damaged by production and construction activities and natural disasters. In the past, land resource data collection mainly relied on manual field measurement. Workers need to carry professional measurement tools such as total stations and levels to the site and measure point by point according to certain specifications and procedures. Specifically, they need to set up instruments at each predetermined measurement point, adjust device parameters to ensure measurement accuracy, and then record the coordinates, elevation, and other related data of the point. This method was the main means of obtaining accurate land information at that time and was widely used in various land-related projects. With the continuous progress of science and technology, remote sensing unmanned aerial vehicle technology has become mature and gradually introduced into the field of land resource data collection. Now the scheme is to let the remote sensing unmanned aerial vehicle carry a camera collection device and combine with a geographic information system to realize the collection of land data. At the same time, remote sensing image processing technology is used to process the images taken by the remote sensing unmanned aerial vehicle, including geometric correction, radiation correction, image enhancement, and classification, and a series of operations, thereby effectively improving the image quality and information extraction capability, so as to more accurately identify and analyze the characteristics and changes of land resources, and on this basis, comprehensively analyze the land consolidation project and develop appropriate management measures.
[0003] The existing remote sensing unmanned aerial vehicle simply relies on its own flight platform to carry out image collection when performing remote sensing flight tasks. Some image collection devices are equipped with lens protection covers for protection, but dust and rain can still fall on the lens protection cover, which may block some key area pixels, causing the image to appear blurred, distorted, and other situations, increasing the difficulty and error rate of data processing. Moreover, there is a lack of effective cleaning measures, and manual intervention is needed to remove dirt on the lens, which not only affects work efficiency, but also makes it difficult to clean in time in harsh environments, affecting the accuracy of the collected data, and thus reducing the reliability and effectiveness of the entire land consolidation engineering image collection data.
[0004] Therefore, there is an urgent need to provide an image collection device for land consolidation engineering to solve the above problems. SUMMARY
[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide an image collection device for land consolidation engineering.
[0006] The technical scheme adopted to solve the above technical problems is: an image acquisition device for land consolidation and rehabilitation projects, comprising a remote sensing unmanned aerial vehicle body, a mounting rack is fixed to the bottom end of the remote sensing unmanned aerial vehicle body through bolts, a first telescopic protective cover is fixed to the bottom end of the mounting rack, and an adjusting plate frame is fixed to the bottom end of the first telescopic protective cover. Four heightening triangular foot supports are fixed to the outside of the adjusting plate frame, a second telescopic protective cover is fixed to the bottom end of the adjusting plate frame, and a mounting shell is fixed to the bottom end of the second telescopic protective cover. A shooting mechanism for collecting land resource data is arranged between the mounting rack and the mounting shell, and an adjusting mechanism for changing the length of the first telescopic protective cover is arranged between the mounting rack and the adjusting plate frame. A replacement mechanism for quickly disassembling and assembling a lens piece is arranged in the mounting shell, and a cleaning mechanism located in the mounting shell is arranged at the bottom end of the replacement mechanism, thereby scraping off dirt on the lens piece.
[0007] Through the above technical scheme, the remote sensing unmanned aerial vehicle body serves as a flight platform, the first telescopic protective cover is arranged between the mounting rack and the adjusting plate frame for protection, and the first telescopic protective cover can be adjusted in length, the second telescopic protective cover is arranged between the adjusting plate frame and the mounting shell for protection, and the second telescopic protective cover can be self-adaptively adjusted, the first telescopic protective cover and the second telescopic protective cover effectively isolate external environmental factors, prolong the service life of the device, and the heightening triangular foot supports can keep the entire device at a certain distance from the ground and provide a landing buffer for the remote sensing unmanned aerial vehicle body, thereby avoiding direct impact of ground protrusions on key components.
[0008] Further, the shooting mechanism comprises an air bag mounting rack fixed to the bottom end of the mounting rack, a shock-absorbing air bag is fixed to the top end of the air bag mounting rack, and a gimbal mounting seat is fixed to the top end of the shock-absorbing air bag.
[0009] Through the above technical scheme, the air bag mounting rack and the gimbal mounting seat are buffered by the shock-absorbing air bag.
[0010] Further, a photographic camera is detachably connected to the bottom end of the gimbal mounting seat, a first clasp joint is fixed to the bottom end of the photographic camera, a second clasp joint is fixed to the top end of the mounting shell, and the first clasp joint and the second clasp joint are detachably connected.
[0011] Through the above technical solution, the gimbal mount is connected to the camera via an interface. When the device vibrates or is impacted during operation, the airbag mount will be the first to receive these external forces. Due to the presence of the shock-absorbing airbag, it will undergo compression deformation when subjected to force, absorbing most of the energy and converting it into its own elastic potential energy, thereby reducing the impact force transmitted to the gimbal mount and the camera. The camera is connected to the second snap ring connector of the mounting housing through the first snap ring connector, ensuring that the camera can maintain a relatively stable position when subjected to the remaining minor impact force, without significant shaking, thus ensuring the stability and clarity of the captured image.
[0012] Furthermore, the adjustment mechanism includes two folding rods rotatably mounted on the bottom of the mounting frame, four folding buffer shells rotatably mounted on the top of the adjustment plate frame, and an electric telescopic rod rotatably mounted between the two folding rods.
[0013] With the above technical solution, when the electric telescopic rod drives the two folding rod frames to rotate to the opposite side, the two folding rod frames drive the four folding buffer shells to fold accordingly. A limiting plate is provided on one side of the folding buffer shell, so that the two folding buffer shells will be spliced together after folding. When the electric telescopic rod drives the two folding rod frames to rotate to opposite sides, the two folding rod frames drive the four folding buffer shells to unfold accordingly. A limiting plate is provided on one side of the folding buffer shell to prevent the folding rod frames and folding buffer shells from folding outward.
[0014] Furthermore, a connecting pivot block is slidably installed inside the folding buffer shell. The interior of the connecting pivot block is rotatably connected to one end of the folding rod frame. A rubber damping block is fixed to one end of the connecting pivot block. The exterior of the rubber damping block is tightly fitted to the interior of the folding buffer shell. A first spring is fixed between the rubber damping block and the folding buffer shell.
[0015] Through the above technical solution, the folding pole is rotatably connected to the folding buffer shell through the connecting pivot block. When the remote sensing drone body falls, the height-increasing tripod will transfer the impact force of the fall to the folding buffer shell through the adjusting plate frame, so that the connecting pivot block moves inside the folding buffer shell through the rubber damping block. The rubber damping block absorbs energy through friction and is buffered by the first spring.
[0016] Furthermore, the replacement mechanism includes a lens mounting piece that is slidably mounted on the mounting housing guide rail, one end of the lens mounting piece is fixed with an opening and closing pull ring, and a switch housing is fixed inside the opening and closing pull ring.
[0017] Through the above technical solution, the lens mounting piece is precisely positioned inside the mounting housing via a guide rail, ensuring that the lens mounting piece is in the optimal position during shooting, thereby improving the image quality of the camera. In addition, both sides of the lens mounting piece are coated to provide oleophobic, hydrophobic, and dustproof protection.
[0018] Furthermore, a second spring is fixed to the inner wall of the switch housing, and a locking block is fixed to one end of the second spring. The outside of the locking block is slidably connected to the inside of the switch housing, and a positioning pressure plate is fixed to the inside of the switch housing by bolts.
[0019] By pressing the locking cylinder with your hand, the locking cylinder separates from the slot of the mounting housing. The old lens mounting piece can then be removed from the mounting housing by opening and closing the pull ring. Similarly, after the new lens mounting piece is installed inside the mounting housing, the second spring will drive the locking cylinder to insert into the slot of the mounting housing, realizing the quick unlocking and locking of the lens mounting piece, simplifying the lens replacement process and improving work efficiency.
[0020] Furthermore, the cleaning mechanism includes belt grooves respectively located on both sides of the inner wall of the mounting housing, a mounting beam fixed between the two belt grooves, a dual-head motor fixed to the outside of the mounting beam, and two first gear shafts fixedly connected to the output shaft of the dual-head motor via a coupling.
[0021] Through the above technical solution, the mounting beam serves as an important support structure for the entire cleaning mechanism. It not only provides a solid mounting foundation for the dual-head motor but also supplies it with power, ensuring that the dual-head motor can operate stably. This allows the cleaning mechanism to move undisturbed within the belt conveyor groove, and enables the dual-head motor to drive the first gear shaft to rotate.
[0022] Furthermore, a second gear shaft is rotatably mounted between the two belt grooves, and two gear belts are externally meshed with the first and second gear shafts, with a cleaning scraper fixed between the two gear belts.
[0023] Through the above technical solution, the first gear shaft drives the gear belt to rotate through the second gear shaft, and the gear belt drives the cleaning scraper to move accordingly, thereby scraping the outside of the lens mounting plate, effectively removing dust and stains from the outside of the lens mounting plate, and improving image quality.
[0024] The beneficial effects of this invention are as follows: (1) The present invention provides a shooting mechanism and an adjustment mechanism. The first telescopic protective cover protects the camera from dust and water by using the second telescopic protective cover. The second telescopic protective cover can be concave and convex. When the second telescopic protective cover is concave, it will block the dust and rainwater around the shooting lens, reducing the image blurring and distortion caused by pollutants and improving the quality of the acquired image. When the second telescopic protective cover is convex, it will reduce the air resistance during flight, improve the flight performance and energy efficiency of the remote sensing UAV, and enable the camera to work stably in environments with sandstorms or frequent rain. (2) The present invention has a cleaning mechanism that can automatically clean the lens mounting plate during flight without manual intervention, reducing the number of repeated acquisitions caused by image quality problems, improving work efficiency, reducing overall operating costs, and the high-quality image data improves the accuracy and scientific nature of land consolidation project decision-making, which helps to better plan and manage project progress. (3) The present invention has a replacement mechanism and a guide groove inside the mounting housing to ensure that the lens mounting piece can be accurately aligned with the optical axis center after each replacement. When the lens mounting piece is severely damaged or contaminated and cannot be used, the operator can replace it with a new lens mounting piece through simple operation. The whole replacement process is quick and convenient, which greatly shortens the equipment downtime and enhances the adaptability and flexibility of the device. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0028] like Figures 1-10As shown, an image acquisition device for land consolidation engineering in this embodiment includes a remote sensing drone body 1. A mounting frame 2 is bolted to the bottom of the drone body 1. A first telescopic protective cover 3 is fixed to the bottom of the mounting frame 2, and an adjusting plate frame 4 is fixed to the bottom of the first telescopic protective cover 3. Four height-increasing tripods 5 are fixed to the outside of the adjusting plate frame 4. A second telescopic protective cover 6 is fixed to the bottom of the adjusting plate frame 4, and a mounting shell 7 is fixed to the bottom of the second telescopic protective cover 6. A shooting mechanism 8 for acquiring land resource data is provided between the mounting frame 2 and the mounting shell 7. The shooting mechanism 8 includes... An airbag mounting bracket 801 is fixed to the bottom of the mounting frame 2. A shock-absorbing airbag 802 is fixed to the top of the airbag mounting bracket 801. A gimbal mounting base 803 is fixed to the top of the shock-absorbing airbag 802. A camera 804 is snapped onto the bottom of the gimbal mounting base 803. A first retaining ring connector 805 is fixed to the bottom of the camera 804. A second retaining ring connector 806 is fixed to the top of the mounting shell 7. The first retaining ring connector 805 and the second retaining ring connector 806 are snapped together. Through the above technical solution, the remote sensing UAV body 1 serves as a flight platform. The mounting frame 2 and the adjustment plate frame 4 are connected by a first telescopic protective barrier. The first telescopic protective cover 3 provides protection, and it is adjustable. The adjustment frame 4 and the mounting shell 7 are protected by the second telescopic protective cover 6, which is self-adjusting. The first and second telescopic protective covers 3 and 6 effectively isolate external environmental factors, extending the equipment's lifespan. The heightening tripod 5 keeps the entire device a certain distance from the ground and provides a landing buffer for the remote sensing UAV body 1, preventing ground protrusions from directly impacting key components. The gimbal mount 803 is connected to the camera 804 via an interface. When vibration occurs during equipment operation, or When subjected to a collision, the airbag mounting bracket 801 will be the first to receive these external forces. Due to the presence of the shock-absorbing airbag 802, it will undergo compression deformation when subjected to force, absorbing most of the energy and converting it into its own elastic potential energy, thereby reducing the impact force transmitted to the gimbal mount 803 and the camera 804. The camera 804 is connected to the second retaining ring connector 806 of the mounting housing 7 through the first retaining ring connector 805, ensuring that the camera 804 can still maintain a relatively stable position when subjected to the remaining small impact force, without significant shaking, thereby ensuring the stability and clarity of the captured image.
[0029] like Figures 3-7As shown, an adjustment mechanism 9 for changing the length of the first telescopic protective cover 3 is provided between the mounting frame 2 and the adjustment plate frame 4. The adjustment mechanism 9 includes two folding rods 901 rotatably mounted at the bottom of the mounting frame 2, four folding buffer shells 902 rotatably mounted at the top of the adjustment plate frame 4, an electric telescopic rod 903 rotatably mounted between the two folding rods 901, a connecting pivot block 904 slidably mounted inside the folding buffer shell 902, the inside of the connecting pivot block 904 rotatably connected to one end of the folding rod 901, and a rubber damping block 905 fixed to one end of the connecting pivot block 904. The exterior of the 05 is tightly fitted to the interior of the folding buffer shell 902. A first spring 906 is fixed between the rubber damping block 905 and the folding buffer shell 902. When the electric telescopic rod 903 drives the two folding rod frames 901 to rotate to the opposite side, the two folding rod frames 901 drive the four folding buffer shells 902 to fold accordingly. A limiting plate is provided on one side of the folding buffer shell 902, so that the two folding buffer shells 902 will be spliced together after folding. This allows the mounting frame 2 and the adjusting plate frame 4 to retract through the first telescopic protective cover 3, reducing the volume of the first telescopic protective cover 3 and reducing the risk of injury during flight. Air resistance is reduced, improving the flight performance and energy efficiency of the remote sensing UAV body 1. When the electric telescopic boom 903 drives the two folding boom frames 901 to rotate to opposite sides, the two folding boom frames 901 drive the four folding buffer shells 902 to unfold accordingly. A limiting plate is provided on one side of the folding buffer shell 902 to prevent the folding boom frames 901 and the folding buffer shells 902 from folding outwards. This allows the mounting frame 2 and the adjusting plate frame 4 to extend through the first telescopic protective cover 3. The adjusting plate frame 4 drives the second telescopic protective cover 6 to move accordingly, thereby forming a surrounding enclosure around the mounting shell 7, preventing the remote sensing UAV body 1 from... During flight, dust or rain splashes onto the lens film. When the remote sensing drone 1 takes off and lands via the heightening tripod 5, the heightening tripod 5 transmits the impact force of the fall to the folding buffer shell 902 through the adjusting plate frame 4. The folding rod 901 is rotatably connected to the folding buffer shell 902 through the connecting pivot block 904. The impact received by the heightening tripod 5 is transmitted to the connecting pivot block 904, causing the connecting pivot block 904 to move inside the folding buffer shell 902 through the rubber damping block 905. The rubber damping block 905 absorbs energy through friction and is buffered by the first spring 906.
[0030] like Figures 8-10As shown, the mounting housing 7 has a lens mounting mechanism 10 for quick lens replacement. The replacement mechanism 10 includes a lens mounting piece 1001 slidably mounted on the guide rail of the mounting housing 7. One end of the lens mounting piece 1001 is fixed with an opening / closing pull ring 1002. A switch housing 1003 is fixed inside the opening / closing pull ring 1002. A second spring 1004 is fixed to the inner wall of the switch housing 1003. One end of the second spring 1004 is fixed with a locking cylinder 1005. The outer side of the locking cylinder 1005 is slidably connected to the inside of the switch housing 1003. A positioning pressure plate 1006 is fixed inside the switch housing 1003 by bolts. The lens mounting piece 1001 is precisely positioned inside the mounting housing 7 via the guide rail, ensuring the lens is securely mounted. The lens mount 1001 is positioned optimally during shooting, improving the image quality of the camera 804. Both sides of the lens mount 1001 are coated for oleophobic, hydrophobic, and dust-proof properties. When replacing the lens mount 1001, pressing the locking cylinder 1005 separates it from the slot in the mounting housing 7, allowing the old lens mount 1001 to be removed from the mounting housing 7 via the opening and closing pull ring 1002. Similarly, after installing the new lens mount 1001 into the mounting housing 7, the second spring 1004 drives the locking cylinder 1005 to insert into the slot in the mounting housing 7, achieving quick unlocking and locking of the lens mount 1001, simplifying the lens replacement process and improving work efficiency.
[0031] like Figures 8-9As shown, the bottom of the replacement mechanism 10 is equipped with a cleaning mechanism 11 located inside the mounting housing 7, which scrapes away dirt from the lens. The cleaning mechanism 11 includes belt grooves 1101 respectively located on both sides of the inner wall of the mounting housing 7. A mounting beam 1102 is fixed between the two belt grooves 1101. A dual-head motor 1103 is fixed to the outside of the mounting beam 1102. The output shaft of the dual-head motor 1103 is fixedly connected to two first gear shafts 1104 via a coupling. A second gear shaft 1105 is rotatably mounted between the two belt grooves 1101. Two gear belts 1106 are meshed on the outside of the first gear shafts 1104 and the second gear shaft 1105. A cleaning scraper 1107 is fixed between the two gear belts 1106. The gimbal mounting base 803 is equipped with... The battery provides power to the camera 804 and the dual-head motor 1103. The mounting beam 1102 provides a mounting base and power supply for the dual-head motor 1103, ensuring that the cleaning mechanism 11 moves undisturbed in the belt movement groove 1101. The dual-head motor 1103 drives the first gear shaft 1104 to rotate, which in turn drives the gear belt 1106 to rotate through the second gear shaft 1105. The gear belt 1106 drives the cleaning scraper 1107 to move within the belt movement groove 1101, thereby scraping the outer side of the lens mounting plate 1001. The cleaning scraper 1107 is made of silicone, which ensures a good fit while avoiding scratches on the lens mounting plate 1001, effectively removing dust and stains from the outer side of the lens mounting plate 1001 and improving image quality.
[0032] The working principle of this embodiment is as follows: The remote sensing UAV body 1 serves as a flight platform, collecting land data for the land consolidation project via the camera 804. The heightening tripod 5 keeps the entire device a certain distance from the ground and provides a landing buffer for the remote sensing UAV body 1, preventing ground protrusions from directly impacting key components. The gimbal mount 803 is connected to the camera 804 via an interface. When the equipment vibrates or is impacted during operation, the airbag mount 801 will be the first to receive these external forces. Due to the presence of the shock-absorbing airbag 802, it will undergo compression deformation under stress, absorbing most of the energy and converting it into its own elastic potential energy, thereby reducing the impact force transmitted to the gimbal mount 803 and the camera 804. The camera 804 is connected to the second retaining ring connector 806 of the mounting housing 7 via the first retaining ring connector 805, ensuring that the camera 804 maintains a relatively stable position even when subjected to residual minor impact force, without significant shaking, thus ensuring the stability and clarity of the captured image. After the remote sensing UAV body 1 takes off, the electric telescopic rod 903 drives the two folding rod frames 901 to rotate to opposite sides. The two folding rod frames 901 drive the four folding buffer shells 902 to fold accordingly. A limiting plate is provided on one side of the folding buffer shell 902, so that the two folding buffer shells 902 will be spliced together after folding. This allows the mounting frame 2 and the adjustment plate frame 4 to retract through the first telescopic protective cover 3, reducing the volume of the first telescopic protective cover 3 and lowering the height of the mounting frame 2. The reduced air resistance during flight improves the flight performance and energy efficiency of the remote sensing UAV 1. The gimbal mount 803 houses a battery, providing power to the camera 804 and the dual-head motor 1103. The mounting beam 1102 provides the mounting base and power supply for the dual-head motor 1103, ensuring the cleaning mechanism 11 operates undisturbed in the belt groove 1101. When dust and dirt accumulate on the outer side of the lens mount 1001, the dual-head motor 1103 drives the first gear shaft 1104 to rotate. The first gear shaft 1104 drives the gear belt 1106 to rotate via the second gear shaft 1105. The gear belt 1106 drives the cleaning scraper 1107 to move within the belt groove 1101, thus cleaning the outer side of the lens mount 1001. The cleaning scraper 1107 is made of silicone, which ensures a good fit while avoiding scratches on the lens mounting plate 1001. It effectively removes dust and stains from the outside of the lens mounting plate 1001, improving image quality. In case of excessive dust or rain, the mounting frame 2 and the adjustment plate frame 4 are protected by a first telescopic protective cover 3, which is adjustable in length. The adjustment plate frame 4 and the mounting housing 7 are protected by a second telescopic protective cover 6, which is self-adjusting. The first and second telescopic protective covers 3 and 6 effectively isolate external environmental factors and extend the equipment's lifespan. At the same time, when the electric telescopic rod 903 drives the two folding rod frames 901 to rotate to opposite sides...Two folding rods 901 drive four folding buffer shells 902 to unfold. A limiting plate is provided on one side of each folding buffer shell 902 to prevent the folding rods 901 and folding buffer shells 902 from folding outwards. This allows the mounting frame 2 and the adjusting plate frame 4 to extend through the first telescopic protective cover 3. The adjusting plate frame 4 then moves the second telescopic protective cover 6, thus forming a surrounding enclosure of the mounting shell 7. This prevents dust or rainwater from splashing onto the lens of the remote sensing drone 1 during flight. When the remote sensing drone 1 lands, the height-increasing tripod 5 transmits the impact force to the folding buffer shells 902 through the adjusting plate frame 4. The folding rods 901 are rotatably connected to the folding buffer shells 902 via connecting pivot blocks 904. The impact received by the height-increasing tripod 5 is transmitted to the connecting pivot blocks 904, causing the connecting pivot blocks 904 to move inside the folding buffer shells 902 via rubber damping blocks 905. Friction absorbs energy, and the first spring 906 provides cushioning. The lens mounting piece 1001 is precisely positioned inside the mounting housing 7 via a guide rail, ensuring it is in the optimal position during shooting and improving the image quality of the camera 804. Both sides of the lens mounting piece 1001 are coated for oleophobic, hydrophobic, and dustproof properties. When the lens mounting piece 1001 is severely damaged or contaminated and cannot be used, pressing the locking cylinder 1005 separates it from the slot in the mounting housing 7, allowing the old lens mounting piece 1001 to be removed from the mounting housing 7 via the opening and closing pull ring 1002. Similarly, after installing the new lens mounting piece 1001 into the mounting housing 7, the second spring 1004 drives the locking cylinder 1005 to insert into the slot in the mounting housing 7, achieving quick unlocking and locking of the lens mounting piece 1001, simplifying the lens replacement process and improving work efficiency.
