[0001] The present invention relates to the technical field of image acquisition equipment, and in particular to an image acquisition equipment for biological control by unmanned aerial vehicles. Background Art

[0002] In today's agricultural and ecological protection fields, drone biological control technology plays an increasingly important role. With its high efficiency and flexibility, drones can quickly cover large areas to monitor and control biological problems such as pests and diseases. In the process of drone biological control, image acquisition equipment is an important tool for obtaining key information.

[0003] Traditional image acquisition equipment for biological control by drones has many problems in practical applications. First, in terms of installation, the connection method with the drone is often complicated and cumbersome, and it takes a lot of time and effort to install and disassemble, which greatly limits the rapid deployment of the equipment in different operating scenarios and reduces work efficiency. In terms of heat dissipation and cleaning functions, traditional equipment has obvious deficiencies. In the complex environment of the field, the lens of the equipment is easily contaminated with dust, debris, etc. The existing cleaning method is not effective and it is difficult to ensure the cleanliness of the lens, which in turn affects the quality of image acquisition.

[0004] In summary, the existing image acquisition equipment for biological control by unmanned aerial vehicles has many defects in terms of installation convenience, stability, heat dissipation and cleaning, and adjustment functions. A new image acquisition equipment is urgently needed to solve these problems. The image acquisition equipment for biological control by unmanned aerial vehicles of the present invention is developed based on such a background. Summary of the invention

The camera device is installed in the installation tube so that its bottom end contacts the buffer pad, and the buffer pad is used to protect the camera device. The threaded installation cover is then rotated to complete the installation of the installation cover and the installation tube. The fixing plate is pressed against the camera device to fix it by rotating the pressing rod, and the camera device can be quickly disassembled and assembled.

The impeller rotates outside the mounting tube due to the flow of wind, and drives the swivel to rotate through the fixing frame, the inertia of the handle is increased by the lead block, and the handle rotates and unfolds on the guide column under the action of centrifugal force until it is blocked by the stop rod, and when the handle rotates, its outer wall slides in contact with the outer wall of the perspective mirror, so that dust and other impurities on the surface of the perspective mirror can be cleaned.

When air cannot enter the outer cover, the impeller cannot rotate, so that the rotating handle rotates and resets under the action of the torsion spring, so that when it is not cleaned again, the rotating handle does not clean on the perspective mirror, so as to prevent affecting the shooting effect of the camera device.

[0009] The present invention is further configured such that the outer wall of the fixing frame is fixedly connected with a wind collecting hood, the outer wall of the wind collecting hood is fixedly connected with a connecting hose, the end of the connecting hose away from the wind collecting hood is fixedly connected with an exhaust pipe, an exhaust groove is provided in the wall of the exhaust pipe, and the outer wall of the exhaust pipe is fixedly connected with the outer wall of the rotating handle. The wind collecting hood on the fixing frame collects the airflow discharged by the impeller, transports it to the exhaust pipe through the connecting hose, and discharges it to the outside through the exhaust groove, so as to blow away the dust, and further enhance the cleaning effect.

The mounting plate is fixed to the bottom end of the drone, and the mounting rod is installed in the block through the sliding connection between the mounting rod and the block, and the threaded mounting pin is rotated to pass through the mounting rod and the block, so that the mounting rod cannot be separated from the mounting plate, which is convenient for quick installation and removal.

Damping blocks are provided at both ends of the slider and slide on the limit rod. When the drone shakes during flight, the slider slides in the mounting rod and squeezes the buffer springs at both ends, playing a buffering role through the damping blocks and buffer springs. The support rod rotates with the movement of the slider to further disperse the vibration.

[0012] The present invention is further configured such that the adjustment device includes a fixed ring, the outer wall of the fixed ring is rotatably connected to the adjustment ring, notches are provided in the walls of the fixed ring and the adjustment ring, the outer wall of the adjustment ring is fixedly connected to the gear ring, a servo motor is provided outside the adjustment ring, and the output end of the servo motor is fixedly connected to the driving gear. The servo motor is started to drive the driving gear to rotate, and since the driving gear is meshed with the gear ring, the adjusting ring is driven to rotate on the fixed ring. At this time, the notches in the walls of the fixed ring and the adjusting ring are opposite, so that the wind generated by the flight of the drone enters the outer cover. On the contrary, when the notches in the walls of the fixed ring and the adjusting ring do not correspond, the wind cannot enter the outer cover.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a fixing device, and the connection between the mounting plate and the drone is simple and efficient.

[0016] 2. The present invention significantly improves the heat dissipation and cleaning functions of the equipment through the coordinated work of the heat dissipation slot and the cleaning component of the acquisition device. The heat dissipation slot can dissipate the heat generated by the camera device in time to ensure the stable performance of the equipment during long-term operation. The cleaning component uses the airflow generated by the rotation of the impeller and the movement of the handle to clean dust and other impurities on the surface of the perspective mirror, and discharge the airflow through the wind condensing hood, connecting hose and exhaust pipe, thereby enhancing the cleaning effect and further optimizing the working environment of the equipment.

[0017] 3. The present invention sets an adjustment device, drives the gear to rotate through a servo motor, and controls the rotation of the adjustment ring on the fixed ring through the cooperation of the driving gear and the gear ring, so as to flexibly control the air intake of the outer cover, thereby controlling the use of the cleaning component in different situations. This adjustment function enables the equipment to adapt to different working environments and heat dissipation requirements, thereby improving the applicability and reliability of the equipment.

[0029] The outer wall of the installation tube 51 is fixedly connected to the inner wall of the outer cover 1, the outer wall of the fixing plate 54 is slidably connected to the outer wall of the camera device 55, and the outer wall of the camera device 55 is slidably connected to the outer wall of the buffer pad 56. The camera device 55 is installed in the installation tube 51 so that its bottom end contacts the buffer pad 56, and the buffer pad 56 protects the camera device 55. Then, the threaded installation cover 52 is rotated to complete the installation of the installation cover 52 and the installation tube 51. By rotating the pressing rod 53 threadedly connected on the installation cover 52, the fixing plate 54 rotatably connected at its bottom end moves downward until the camera device 55 is pressed tightly to achieve fixation.

[0030] The cleaning assembly 6 includes an impeller 61, the outer wall of the impeller 61 is fixedly connected to a fixing frame 64, the outer wall of the fixing frame 64 is fixedly connected to a swivel 62, the inner wall of the swivel 62 is fixedly connected to a guide column 65, the outer wall of the guide column 65 is rotatably connected to a handle 66, the outer wall of the handle 66 is fixedly connected to a torsion spring 67, the outer wall of the handle 66 is fixedly connected to a lead block 611, and a blocking rod 63 is arranged inside the swivel 62.

[0031] The inner wall of the impeller 61 is rotatably connected to the outer wall of the mounting tube 51, the outer wall of the rotating ring 62 is rotatably connected to the bottom end of the mounting tube 51, the outer wall of the rotating handle 66 is slidably connected to the outer wall of the perspective mirror 58, the end of the torsion spring 67 away from the rotating handle 66 is fixedly connected to the outer wall of the guide column 65, and the outer wall of the blocking rod 63 is slidably connected to the outer wall of the rotating handle 66. During the process of wind discharge, the impeller 61 is driven to rotate on the outer wall of the mounting tube 51, and the fixed rotating ring 62 is driven to rotate through the connection of the fixing frame 64. The fixed lead block 611 increases the inertia of the rotating handle 66 during rotation. Under the action of centrifugal force, the rotating handle 66 rotates and unfolds on the outer wall of the guide column 65 until it is blocked by the blocking rod 63. When the rotating handle 66 rotates, its outer wall slides and contacts with the outer wall of the perspective mirror 58, so as to clean the dust and other impurities on the surface of the perspective mirror 58.

[0032] The outer wall of the fixed frame 64 is fixedly connected to a wind collecting hood 69, the outer wall of the wind collecting hood 69 is fixedly connected to a connecting hose 610, the end of the connecting hose 610 away from the wind collecting hood 69 is fixedly connected to an exhaust pipe 68, an exhaust groove 612 is opened in the wall of the exhaust pipe 68, and the outer wall of the exhaust pipe 68 is fixedly connected to the outer wall of the rotating handle 66.

[0033] The fixing device 3 includes a mounting plate 36, the outer wall of the mounting plate 36 is fixedly connected with a clamping block 37, the inner wall of the clamping block 37 is threadedly connected with a mounting pin 38, the inner wall of the clamping block 37 is slidably connected with a mounting rod 35, the inner wall of the mounting rod 35 is symmetrically slidably connected with a slider 32, the inner wall of the slider 32 is rotatably connected with a support rod 31, the inner wall of the mounting rod 35 is symmetrically fixedly connected with a limiting rod 34, and the outer wall of the slider 32 is symmetrically fixedly connected with a buffer spring 33.

[0034] The outer wall of the mounting pin 38 is threadedly connected to the inner wall of the mounting rod 35, the inner wall of the slider 32 is slidably connected to the outer wall of the limiting rod 34, the end of the buffer spring 33 away from the slider 32 is fixedly connected to the inner wall of the mounting rod 35, and the end of the support rod 31 away from the slider 32 is rotatably connected to the outer wall of the fixed plate 2 through a rotating shaft.

[0035] The adjusting device 4 includes a fixed ring 44, the outer wall of which is rotatably connected to an adjusting ring 43, notches 46 are provided in the walls of the fixed ring 44 and the adjusting ring 43, a gear ring 45 is fixedly connected to the outer wall of the adjusting ring 43, a servo motor 41 is arranged outside the adjusting ring 43, and a driving gear 42 is fixedly connected to the output end of the servo motor 41. When the servo motor 41 is started, the fixedly connected driving gear 42 is driven to rotate, and since the driving gear 42 is meshed with the gear ring 45, the adjusting ring 43 is driven to rotate on the fixed ring 44. At this time, the notches 46 provided in the walls of the fixed ring 44 and the adjusting ring 43 are opposite, so that the wind generated by the flight of the drone enters the outer cover 1, and vice versa, when the notches 46 in the fixed ring 44 and the adjusting ring wall 43 do not correspond, the wind cannot enter the outer cover 1.

[0036] The inner wall of the fixing ring 44 is fixedly connected to the outer wall of the top end of the mounting tube 51 , the servo motor 41 is fixedly connected to the outer wall of the fixing plate 2 through the frame, and the driving gear 42 is meshed with the gear ring 45 .

[0037] Working principle:

[0038] When in use, the fixing device 3 can make the collection device 5 and the drone quickly installed and disassembled, and use the buffer spring 33 and the rotatable support rod 31 to effectively buffer the impact of the drone's flight vibration on the equipment; the collection device 5 uses the pressing rod 53 and the fixing plate 54 to fix the camera device 55 to ensure the stability of image collection, and also achieves heat dissipation and lens cleaning through the synergistic effect of the heat dissipation groove 57 and the cleaning component 6; the adjustment device 4 controls the wind entering the outer cover 1 through the cooperation of the driving gear 42 and the gear ring 45. These devices cooperate with each other, so that the image collection device can stably and clearly collect images during the drone biological control operation, providing strong data support for biological control work;

[0039] In daily use, the mounting plate 36 is fixed to the bottom end of the drone, and the mounting rod 35 is installed in the block 37 through the sliding connection between the mounting rod 35 and the block 37, and the threaded mounting pin 38 is rotated to pass through the block 37 and the mounting rod 35, so that the mounting rod 35 cannot be separated from the mounting plate 36, which is convenient for quick installation and removal. When the drone shakes during flight, the slider 32 slides in the mounting rod 35 and squeezes the buffer springs 33 at both ends, and the damping block and the buffer spring 33 play a buffering role. The support rod 31 rotates with the movement of the slider 32 to further disperse the vibration and ensure that the image acquisition device is stably connected to the drone.

[0040] The camera device 55 is installed in the installation tube 51 so that its bottom end contacts the buffer pad 56. The camera device 55 is protected by the buffer pad 56. Then the threaded installation cover 52 is rotated to complete the installation of the installation cover 52 and the installation tube 51. The fixing plate 54 is pressed against the camera device 55 by rotating the pressing rod 53 to fix it. The camera device 55 can be quickly disassembled and assembled for easy maintenance. The perspective mirror 58 in the wall of the installation tube 51 is used to transmit light when shooting, ensuring that the camera device 55 can clearly capture images. It can also protect the lens of the camera device 55. Through the heat dissipation groove 57 provided on the outside of the installation tube 51, the camera device 55 can also dissipate the heat generated in the installation tube 51.

[0041] When the drone is flying and collecting images through the camera device 55, the servo motor 41 in the adjustment device 4 is started to drive the driving gear 42 to rotate. Since the driving gear 42 is meshed with the gear ring 45, the adjustment ring 43 is driven to rotate on the fixed ring 44 until the notches 46 in the walls of the fixed ring 44 and the adjustment ring 43 are opposite, so that the wind generated by the drone flying enters the outer cover 1, and part of the wind enters through the heat dissipation slots 57 provided on the outside of the mounting tube 51, thereby enhancing the heat dissipation effect;

[0042] The wind passing through the regulating device 4 is finally discharged from the bottom end of the outer cover 1. During the discharge process, the impeller 61 is driven to rotate outside the mounting tube 51, and the rotating ring 62 is driven to rotate through the connection of the fixing frame 64. The lead block 611 increases the inertia of the rotating handle 66 during rotation. Under the action of centrifugal force, the rotating handle 66 rotates and unfolds on the guide column 65 until it is blocked by the blocking rod 63. When the rotating handle 66 rotates, its outer wall slides and contacts with the outer wall of the perspective mirror 58, which can clean the dust and other impurities on the surface of the perspective mirror 58. At the same time, the wind collecting cover 69 on the fixing frame 64 collects the airflow discharged by the impeller 61, transports it to the exhaust pipe 68 through the connecting hose 610, and discharges it to the outside through the exhaust groove 612, blowing away the dust, further enhancing the cleaning effect;

[0043] After cleaning is completed, the servo motor 41 is started again to drive the adjusting ring 43 to rotate and reset, so that the notches 46 on the adjusting ring 43 and the fixing ring 44 no longer correspond to each other. At this time, air cannot enter the outer cover 1, so that the impeller 61 cannot rotate, and the rotating handle 66 rotates and resets under the action of the torsion spring 67, so that when cleaning is not done again, the rotating handle 66 will not clean on the perspective mirror 58 to prevent affecting the shooting effect of the camera device 55.

[0044] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
