Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a UAV-based rice pest monitoring device. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants. They are remotely controlled from the ground or controlled by GPS to spray pesticides, seeds, powders, etc. Nowadays, drones are also commonly used for farmland inspection to facilitate the acquisition of information on crop growth and farmland environment. However, during operation, drones are affected by the farmland environment, and their movement disturbs the air, raising dust. The large amount of dust in the air can easily contaminate the lens of the drone, affecting the quality of the captured images.

[0003] To address this, Chinese patent CN219313042U discloses a farmland environment monitoring drone that provides a remote cleaning function for the mirror surface of the environmental monitoring drone. When the image transmitted back is not clear enough, the drone uses remote control to transmit a signal to a signal receiver. The signal receiver then activates a servo motor through a controller. The servo motor drives a lead screw to rotate, causing the scraper to slide up and down along the surface of the mirror, thereby achieving remote automatic cleaning of the mirror surface and improving the clarity of aerial photography.

[0004] However, the movement of the scraper also consumes a lot of energy, affecting the drone's battery life. Furthermore, the drone will vibrate during movement, which will affect the quality of aerial images.

Detailed Implementation

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-4A rice pest monitoring device based on a drone is installed on the frame 1 of the drone. The monitoring device includes a connecting structure 2. A flight component 11 and an observation component 12 are arranged on the frame 1, and a mounting base 13 is installed on the frame 1. The observation component 12 includes a mounting platform 121 and cameras 122. At least three cameras 122 are provided and are mounted on the mounting platform 121. The multiple cameras 122 are symmetrically distributed about the axis of the connecting rod 211. The connecting structure 2 includes a connecting component 21 and an airbag 22. The connecting component 21 includes a connecting rod 211, a fixing cover 212, a first elastic element 213, and a hinge seat 214. Both ends of the connecting rod 211 are respectively provided with limiting The positioning plate 2111 and the hinge joint 2112 are connected, and the connecting rod 211 is slidably engaged with the fixed cover 212. The limiting plate 2111 is slidably engaged with the mounting base 13. The fixed cover 212 is mounted on the frame 1 and is connected to the mounting base 13. There are two first elastic members 213. The two ends of one first elastic member 213 are respectively connected to the mounting base 13 and the limiting plate 2111, and the two ends of the other first elastic member 213 are respectively connected to the limiting plate 2111 and the fixed cover 212. The hinge seat 214 is rotatably mounted on the mounting platform 121 and is hinged to the hinge joint 2112 of the connecting rod 211. The airbag 22 is mounted on the mounting platform 121 and is located between the mounting platform 121 and the frame 1.

[0037] This invention achieves the function of protecting the camera 122 through the frame 1 and the connecting structure 2. When the drone shakes, it buffers the impact and reduces the vibration of the camera 122, solving the problem that the camera 122 is easily damaged when shaking. The camera 122 is installed below the mounting platform 121. When the drone shakes, the main body of the frame 1 shifts and shakes. Under the action of inertia, the two first elastic elements 213 deform, and the hinge joint 2112 of the connecting rod 211 rotates relative to the hinge seat 214, thereby compressing the airbag 22. The airbag 22 and the first elastic elements 213 absorb the vibration, buffer the impact and vibration of the camera 122, and protect the camera 122. At the same time, when performing shooting tasks, the airbag 22 and the first elastic elements 213 can stabilize the camera 122, thereby improving the quality of the captured images and improving the accuracy of monitoring.

[0038] Reference Figure 1 , Figures 5-7The mounting platform 121 is also equipped with a cleaning device 3 and a driving structure 4. The cleaning device 3 includes a wiping assembly 31, a pushing assembly 32, and a limiting ring 33. The wiping assembly 31 includes a first mounting ring 311, a cleaning block 312, and a second elastic member 313. The first mounting ring 311 is movably mounted on the mounting platform 121 and slides in cooperation with the housing of the camera 122. Multiple cleaning blocks 312 are provided, each corresponding to one of the cameras 122. The cleaning blocks 312 are mounted on the first mounting ring 311 and slide in cooperation with the lens of the camera 122. The two ends of the second elastic member 313 are respectively... The first mounting ring 311 and the limiting ring 33 are connected together; the pushing assembly 32 includes a second mounting ring 321 and a third elastic member 322; the two ends of the third elastic member 322 are respectively connected to the second mounting ring 321 and the mounting platform 121; the outer diameter of the second mounting ring 321 is larger than the inner diameter of the first mounting ring 311, and in the working state, when the second mounting ring 321 descends, it will push the first mounting ring 311; the limiting ring 33 is connected to the camera 122 and is located below the camera 122; the mounting platform 121 is also provided with a driving structure 4 for driving the second mounting ring 321 to move.

[0039] This invention achieves a self-cleaning function for the lens of the camera 122 through a cleaning device 3 and a driving structure 4, enabling automatic cleaning of the lens during operation and preventing dust accumulation on the lens from affecting image quality. A first mounting ring 311 and a second mounting ring 321 are positioned below the mounting platform 121, with the second mounting ring 321 located between the first mounting ring 311 and the mounting platform 121. A limiting ring 33 is connected to the housing of the camera 122. During operation, the driving structure 4 controls the second mounting ring 321 to rise, causing the second elastic element 313 to contract under pressure. Simultaneously, the elastic force generated by the second elastic element 313 pushes the first mounting ring 311 and the cleaning block 312 to reset. When the second elastic element 313 contracts to its limit, the first mounting ring 311 and the cleaning block 312 complete their reset, and then the driving structure 4 stops driving the first mounting ring 311. 11. The cleaning block 312 slides rapidly downward under the elastic force of the second elastic member 313 and compresses the third elastic member 322. Due to the deformation of the third elastic member 322 and the second elastic member 313, the first mounting ring 311 will still rebound and slide upward when it moves to the bottom. The elastic force of the third elastic member 322 is greater than that of the second elastic member 313. After the first mounting ring 311 returns to stability, the first mounting ring 311 and the cleaning block 312 will be at the bottom until the drive structure 4 pushes the second mounting ring 321 again. The cleaning block 312 gradually resets under the elastic force of the second elastic member 313 so as to perform self-cleaning again.

[0040] Reference Figure 1 , Figure 5 , Figure 7 and Figure 8The drive structure 4 includes a power storage component 41 and a linear drive component 42. The power storage component 41 includes a support rod 411, a fourth elastic element 412, a rack 413, a first bracket 414, a first rotating shaft 415, and a first rotating gear 416. Multiple support rods 411 are provided, each corresponding to a camera 122. The support rods 411 are slidably mounted on the mounting platform 121, and the top of each support rod 411 has an abutment portion 4111, which slides in cooperation with the frame 1. The fourth elastic element 412... Both ends are connected to the abutment portion 4111 of the support rod 411 and the mounting platform 121 respectively; the rack 413 is connected to the bottom of the support rod 411; the first bracket 414 is mounted on the mounting platform 121; the first rotating shaft 415 is rotatably mounted on the first bracket 414; the first rotating gear 416 is sleeved on the first rotating shaft 415 and meshes with the rack 413; the linear drive assembly 42 is disposed on the mounting platform 121 and is used to control the movement of the second mounting ring 321, and the linear drive assembly 42 is connected to the first rotating gear 416 in a transmission connection.

[0041] The present invention realizes the function of driving the second mounting ring 321 to move through the energy storage component 41 and the linear drive component 42. The airbag 22 and the first elastic element 213 achieve the effect of storing energy and automatically controlling the movement of the second mounting ring 321 after the energy storage is completed, without the need for additional energy supply, thereby reducing the impact on the flight time of the UAV. During operation, the drone takes off, and the wind it generates stirs up dust on the ground. Then, due to inertia, the first elastic element 213 between the limiting plate 2111 and the mounting base 13 extends, increasing the distance between the mounting platform 121 and the frame 1. It then self-resets. During this process, the fourth elastic element 412 contracts, causing the support rod 411 to slide accordingly, which in turn moves the rack 413. The rack 413 drives the first rotating gear 416, which is connected to it, to rotate. The first rotating gear 416 drives the first rotating shaft 415 to rotate. The first rotating shaft 415 controls the second mounting ring 321 to rise via the linear drive assembly 42. The second elastic element 313 contracts under pressure, and simultaneously, the elastic force generated by the second elastic element 313 pushes the first mounting ring 311 and the cleaning block 312 to reset. When the second elastic element 313 contracts to its limit, the first mounting ring 311 and the cleaning block 312 are reset. Then, the drive structure 4 stops driving the first mounting ring 311. The cleaning block 312 slides down rapidly under the elastic force of the second elastic element 313 and compresses the third elastic element 322. Due to the deformation of the third elastic element 322 and the second elastic element 313, the first mounting ring 311 will still rebound and slide up when it moves to the bottom. The elastic force of the third elastic element 322 is greater than that of the second elastic element 313. After the first mounting ring 311 returns to stability, the first mounting ring 311 and the cleaning block 312 will be at the bottom until the drive structure 4 pushes the second mounting ring 321 again. The cleaning block 312 gradually resets under the elastic force of the second elastic element 313 so as to perform self-cleaning again.

[0042] Reference Figure 1 , Figure 7 and Figure 10The mounting platform 121 is also provided with a transmission structure 5 for transmitting power between the first rotating shaft 415 and the linear drive assembly 42. The transmission structure 5 includes a one-way transmission assembly 51 and a synchronous transmission assembly 52. ​​The one-way transmission assembly 51 includes a second bracket 511, a second rotating shaft 512, a ratchet 513, a third mounting ring 514, and a stop pawl 515. The second bracket 511 is mounted on the mounting platform 121. The second rotating shaft 512 is rotatably mounted on the second bracket 511, and the axis of the second rotating shaft 512 is collinear with the axis of the first rotating shaft 415. The ratchet 513 is sleeved on the second rotating shaft 512. The third mounting ring 514 is mounted on the first rotating gear 416. The stop pawl 515 is mounted on the third mounting ring 514 and meshes with the ratchet 513. The synchronous transmission assembly 52 is set on the limiting ring 33, and its two ends are respectively transmitted to the second rotating shaft 512 and the linear drive assembly 42.

[0043] The present invention realizes the function of connecting the first rotating shaft 415 and the linear drive component 42 through the unidirectional transmission component and the synchronous transmission component 52, so that the rack 413 can only drive the linear drive component 42 in one direction, avoiding the problem of the rack 413 repeatedly moving under the elastic force of the fourth elastic element 412 and doing useless work. During operation, when the frame 1 shakes, the airbag 22 is compressed, the corresponding fourth elastic element 412 contracts, and the support rod 411 slides accordingly, thereby driving the rack 413 to move. During this movement, the rack 413 drives the first rotating gear 416, which is connected to it, to rotate. The first rotating gear 416 drives the first rotating shaft 415 and the mounting ring to rotate. The mounting ring drives the stop pawl 515 to rotate. When the support rod 411 and rack 413 descend, the first rotating shaft 415 rotates in the forward direction, and the stop pawl 515 drives the ratchet 513, which is meshed with it, to rotate. The ratchet 513 drives the second rotating shaft 512 to rotate, and the second rotating shaft 512 drives the linear drive assembly 42 through the synchronous transmission assembly 52. The linear drive assembly 42 drives the second mounting ring 321 to rise, and the third elastic element 322 contracts to store energy. When the support rod 411 and rack 413 rise, the first rotating shaft 415 rotates in the opposite direction, and the stop pawl 515 will not drive the ratchet 513 to rotate, thus avoiding affecting the energy storage of the second mounting ring 321. When the second mounting ring 321 moves to the upper limit position, the third elastic element 322 is compressed to the limit. At this time, the linear drive assembly 42 is disconnected from the second mounting ring 321. Under the elastic force of the third elastic element 322, the second mounting ring 321 moves rapidly downward, thereby pushing the first mounting ring 311. The first mounting ring 311 drives the cleaning block 312 to move, performing self-cleaning operation.

[0044] Reference Figures 7-9The synchronous transmission assembly 52 includes a third bracket 521, a third rotating shaft 522, a bevel gear 523, a bevel gear ring 524, a first sleeve 525, and a first synchronous belt 526. Multiple third brackets 521, third rotating shafts 522, and bevel gears 523 are provided, each corresponding to a camera 122. The third bracket 521 is mounted on a limiting ring 33. The third rotating shaft 522 is rotatably mounted on the third bracket 521. The bevel gear 523 is sleeved on the third rotating shaft 522. The bevel gear ring 524 is rotatably mounted on the limiting ring 33, and the bevel gear 523 and bevel gear ring 524 are connected in a transmission connection. The linear drive assembly 42 is also connected in a transmission connection with the bevel gear ring 524. Two first sleeves 525 are provided, and the two first sleeves 525 are respectively sleeved on the second rotating shaft 512 and the third rotating shaft 522. The two sides of the first synchronous belt 526 are respectively straddled on the two first sleeves 525.

[0045] The present invention realizes the function of connecting multiple second rotating shafts 512 through the third bracket 521, the third rotating shaft 522, the bevel gear 523, the bevel gear ring 524, the first sleeve 525 and the first synchronous belt 526, so that multiple racks 413 can drive the bevel gear ring 524 to rotate, and the bevel gear ring 524 is controlled to rotate in one direction through the one-way transmission component 51 to continuously store power. During operation, when the frame 1 shakes, the airbag 22 is compressed, the corresponding fourth elastic element 412 contracts, and the support rod 411 slides accordingly, thereby driving the rack 413 to move. During this movement, the rack 413 drives the first rotating gear 416, which is connected to it, to rotate. The first rotating gear 416 drives the first rotating shaft 415 and the mounting ring to rotate. The mounting ring drives the stop pawl 515 to rotate. When the support rod 411 and rack 413 descend, the first rotating shaft 415 rotates forward, and the stop pawl 515 drives the ratchet 513, which is meshed with it, to rotate. The ratchet 513 drives the second rotating shaft 512 to rotate. The second rotating shaft 512, through the transmission of the first sleeve 525 and the first synchronous belt 526, drives the third rotating shaft 522 to rotate. The third rotating shaft 522 drives the bevel gear 523 to rotate. 23 drives the bevel gear ring 524 to rotate, which in turn drives the linear drive assembly 42. The linear drive assembly 42 drives the second mounting ring 321 to rise, and the third elastic element 322 contracts to store force. When the support rod 411 and rack 413 rise, the first rotating shaft 415 rotates in the opposite direction, and the stop pawl 515 will not drive the ratchet gear 513 to rotate, thus avoiding affecting the storage of force in the second mounting ring 321. When the second mounting ring 321 moves to the upper limit position, the third elastic element 322 is compressed to the limit. At this time, the linear drive assembly 42 is disconnected from the second mounting ring 321. Under the elastic force of the third elastic element 322, the second mounting ring 321 moves rapidly downward, thereby pushing the first mounting ring 311. The first mounting ring 311 drives the cleaning block 312 to move, performing self-cleaning operation. When the bevel gear 523 drives the bevel ring 524 to rotate, the bevel ring 524 will also drive the other bevel gears 523 to rotate. The bevel gears 523 drive the third rotating shaft 522 to rotate. The third rotating shaft 522 drives the second rotating shaft 512 to rotate through the first synchronous belt 526. The second rotating shaft 512 drives the ratchet 513 to rotate, but the ratchet 513 will not drive the stop pawl 515 to rotate.

[0046] Reference Figure 5 , Figure 6 and Figure 11The linear drive assembly 42 includes an internal gear ring 421, a fourth rotating shaft 422, a second rotating gear 423, a reciprocating lead screw 424, a second sleeve 425, a second synchronous belt 426, a push plate 427, and a guide rod 428. The internal gear ring 421 is rotatably mounted on the limiting ring 33 and connected to the bevel gear ring 524, with the axis of the internal gear ring 421 collinear with the axis of the bevel gear ring 524. The fourth rotating shaft 422 is rotatably mounted on the limiting ring 33. The second rotating gear 423 is sleeved on the fourth rotating shaft 422, and the second rotating gear... Wheel 423 meshes with internal gear ring 421; reciprocating screw 424 is rotatably mounted on mounting platform 121 and threadedly connected to push plate 427; two second sleeves 425 are provided, and the two second sleeves 425 are respectively sleeved on fourth rotating shaft 422 and reciprocating screw 424; the two sides of second synchronous belt 426 are respectively straddled on the two second sleeves 425; guide rod 428 is mounted on mounting platform 121; push plate 427 slides with guide rod 428, and push rod can be separated and abuts against second mounting ring 321.

[0047] This invention achieves the function of driving the second mounting ring 321 to move through an internal gear ring 421, a fourth rotating shaft 422, a second rotating gear 423, a reciprocating screw 424, a second sleeve 425, a second synchronous belt 426, a push plate 427, and a guide rod 428. When the airbag 22 is compressed, the fourth elastic element 412 in the corresponding direction contracts, the support rod 411 slides accordingly, and thus drives the rack 413 to move. During the movement, the rack 413 drives the first rotating gear 416 connected to it to rotate. The first rotating gear 416 drives the first rotating shaft 415 and the mounting ring to rotate. The mounting ring drives the stop pawl 515 to rotate. When the support rod 411 and the rack 413 descend, the first rotating shaft 415 rotates in the forward direction. The stop pawl 515 drives the ratchet 513 connected to it to rotate. The ratchet 513 drives the second rotating shaft 512 to rotate. The second rotating shaft 512 drives the third rotating shaft 522 to rotate through the transmission of the first sleeve 525 and the first synchronous belt 526. The three rotating shafts 522 drive the bevel gear 523 to rotate, the bevel gear 523 drives the bevel ring 524 to rotate, the bevel ring 524 drives the internal gear ring 421 to rotate, the internal gear ring 421 drives the second rotating gear 423 connected to it to rotate, the second rotating gear 423 drives the fourth rotating shaft 422 to rotate, the fourth rotating shaft 422 drives the reciprocating screw 424 to rotate through the transmission of the second sleeve 425 and the second synchronous belt 426, the reciprocating screw 424 drives the push plate 427 connected to it to move, and then drives the second mounting ring 321 to rise through the push plate 427, and the third elastic element 322 to contract to store force. After the force is stored, the push plate 427 is separated from the second mounting ring 321 to perform the cleaning action.

[0048] Reference Figure 6 , Figure 10 and Figure 12The push plate 427 is also provided with an auxiliary control structure 6, which includes an abutment component 61 and a control component 62. The abutment component 61 includes a slider 611, a fifth elastic element 612, and a locking block 613. The slider 611 is slidably mounted on the push plate 427, and an oblique notch is provided at one end of the slider 611 away from the axis of the first mounting ring 311. The two ends of the fifth elastic element 612 are respectively connected to the slider 611 and the push plate 427. The locking block 613 is disposed on the second mounting ring 321. The control component 62 is disposed on the mounting platform 121 and is used to control the sliding of the slider 611. In the working state, when the push plate 427 moves from between the mounting platform 121 and the second mounting ring 321 to between the second mounting ring 321 and the limiting piece 2111, when the push plate 427 passes the locking block 613, the locking block 613 squeezes the oblique notch of the slider 611, the fifth elastic element 612 is compressed, and the push plate 427 passes through the second mounting ring 321.

[0049] This invention achieves the function of controlling the contact and separation of the push plate 427 and the second mounting ring 321 through the contact component 61 and the control component 62. During power accumulation, the push plate 427 moves upward, which drives the slider 611 to move synchronously. The slider 611 pushes the locking block 613 on the second mounting ring 321, thereby pushing the second mounting ring 321 upward. After power accumulation is completed, the control component 62 controls the slider 611 to move, overcoming the elastic force of the fifth elastic element 612, and controls the slider 611 to move away from the locking block 613 until the slider 611 separates from the locking block 613. Under the elastic force of the third elastic element 322, the second mounting ring 321 moves rapidly downward, thereby pushing the first mounting ring 311 to move, performing self-cleaning. Then, the sliding of the support rod 411 will continue to control the rotation of the reciprocating screw 424. The reciprocating screw 424 drives the push plate 427 to move upward. When the push plate 427 passes the locking block 613, the slider 611 is squeezed by the locking block 613 and slides towards the axis of the second mounting ring 321, so that the push plate 427 can pass smoothly through the second mounting ring 321. When the push plate 427 moves to the upper limit, the rotation of the reciprocating screw 424 will drive the push plate 427 to move downward and store force again.

[0050] Reference Figure 2 , Figures 12-14 The control component 62 includes a fixing block 621; the fixing block 621 is mounted on the mounting platform 121; the slider 611 has a groove 622; in the working state, when the push plate 427 approaches the fixing block 621, the fixing block 621 will squeeze the groove 622 of the slider 611, pushing the slider 611 to move away from the locking block 613.

[0051] This invention achieves the function of controlling the movement of the slider 611 through the fixing block 621 and the inclined groove 622, realizing the effect of automatically controlling the slider 611 to separate from the locking block 613 when the push plate 427 moves to the top. During the charging process, the push plate 427 moves upward, which drives the slider 611 to move synchronously. The slider 611 pushes the locking block 613 on the second mounting ring 321, thereby pushing the second mounting ring 321 to rise. After the slider 611 contacts the fixing block 621, the fixing block 621 squeezes the inclined groove 622 of the slider 611, overcoming the elastic force of the fifth elastic element 612 and driving the slider 611 to move away from the locking block 613 until the slider 611 separates from the locking block 613. The second mounting ring 321 moves rapidly downward under the elastic force of the third elastic element 322, thereby pushing the first mounting ring 311 to move for self-cleaning. Then, the sliding of the support rod 411 will continue to control the rotation of the reciprocating screw 424. The reciprocating screw 424 drives the push plate 427 to move upward. When the push plate 427 passes the locking block 613, the slider 611 is squeezed by the locking block 613 and slides towards the axis of the second mounting ring 321, so that the push plate 427 can pass smoothly through the second mounting ring 321. When the push plate 427 moves to the upper limit, the rotation of the reciprocating screw 424 will drive the push plate 427 to move downward and store force again.

[0052] Reference Figure 2 The airbag 22 is equipped with a compression spring for supporting the airbag 22; and the bottom of the airbag 22 is provided with multiple air outlets 221, which are located at the lens of the camera 122.

[0053] This invention achieves the effect of blowing away dust adhering to the lens of the camera 122 when the airbag 22 is compressed by using a compression spring and an air outlet 221, thereby further improving the self-cleaning performance. When the airbag 22 is compressed, the gas inside it is ejected from the air outlet 221, thereby blowing away the dust adhering to the lens of the camera 122. At the same time, after the external force is removed, the airbag 22 returns to its original shape under the elastic force of the compression spring, maintaining its cushioning function.

[0054] Reference Figure 5 A rotary handle 43 is sleeved on the reciprocating lead screw 424.

[0055] This invention enables manual control of the power storage state by rotating the handle 43. When the push plate 427 resets slowly, the operator can rotate the handle 43 to control the reciprocating screw 424, thereby controlling the movement of the push plate 427 and enabling it to reset quickly.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
