Description

Technical Field

[0001] The invention relates to the technical field of distance measurement, and in particular to a bamboo leaf frog jumping research platform and a measurement method. Background Art

[0002] The bamboo leaf frog is an amphibian of the genus Rana in the family Ranidae. The bamboo leaf frog is small in size and has smooth skin. The back is usually light brown with dorsal folds and green outside the folds. The head is long, the snout is rounded, and the snout ridges are obvious. The limbs are slender, and there are horizontal stripes on the thighs of the hind limbs. They mostly live near streams or waterfalls in mountainous areas with lush vegetation, and often squat on mosses by the water. The bamboo leaf frog's long-distance movement is mostly by jumping. Therefore, the study of the bamboo leaf frog's jumping mechanism and the distance and method of jumping is of great scientific significance.

[0003] Existing research on bamboo leaf frog jumping generally studies the jumping height and jumping distance of different bamboo leaf frogs, and the jumping distance or jumping arc of the same bamboo leaf frog at different heights and in different environments (sand, soil, silt). However, in fact, the same type of bamboo leaf frog in the same area often encounters an uneven ground instead of the flat ground simulated in the laboratory. When facing this kind of actual ground, the active jumping distance of the bamboo leaf frog will be obviously disturbed by the organism itself, and the measurement is generally carried out with a ruler, etc., and the starting jumping position of the bamboo leaf frog, such as the ground or the height of the lotus leaf, tree branch, etc., is also different.

[0021] The present invention also provides a preferred technical solution, a method for measuring a bamboo leaf frog jumping research platform, characterized in that the method comprises the following steps:

[0022] S1. Preparation: Debug the drive motor and servo motor to ensure that they work normally, and adjust the forward and reverse rotation of the servo motor as needed;

[0023] S2, adjusting the camera surface, wiping the surface of the mesh screen to ensure that there is no dust, placing the required number of motion cameras on the corresponding fourth support plate, debugging the motion cameras, and setting the shutter buttons of multiple motion cameras to be opened at the same time;

[0024] S3, adjust the initial jumping position of the bamboo leaf frog: first, insert the positioning rod through the positioning plug block and then insert it into the surface of the research operation platform, then start the driving motor, the driving motor drives the first threaded rod to rotate, under the limit of the second limit slider and the third support plate on the bamboo leaf frog jumping platform, the first threaded rod rotates to drive the bamboo leaf frog jumping platform to rise and fall, adjust the initial jumping height of the bamboo leaf frog for the first time, and in this process, the first threaded rod drives the rotating rod to rotate through the central transmission rod, and finally the bamboo leaf frog jumping platform rises to the corresponding position. At the same time, when the threaded sleeve does not move, the first threaded rod will drive the mesh curtain to rise, and as the mesh curtain rises, more grids can also be displayed to assist the sliding rod to record data;

[0025] S4, adjust the bamboo leaf frog landing ground: start the servo motor to drive the main driving part to work, and at this time let the driving gear rotate clockwise. When the driving gear rotates clockwise, the two ratchet gear rings rotate in the same direction, that is, at this time, the rotation of the driving gear will only drive the second driven rod to rotate and will not drive the first driven rod to rotate, and will not start the left lifting adjustment part to move, that is, the main driving part starts to drive the multiple slope simulation components to rotate. At this time, when the multiple slope simulation components rotate, the bamboo leaf frog landing simulation platform will be pushed out to different heights, and finally the bamboo leaf frog landing simulation platform will form different slopes;

[0026] S5, start the bamboo leaf frog jumping experiment: put a bamboo leaf frog on the bamboo leaf frog jumping pad, so that its front side faces the first support plate, and food can be hung on the first support plate or light can be used to drive the bamboo leaf frog to jump in the positive direction of the first support plate. When the bamboo leaf frog jumps, start the motion camera to take pictures;

[0027] S6, multiple recording experiment: Repeat steps S and S multiple times, but adjust the bamboo leaf frog take-off platform to different heights, and use multiple slope simulation components to allow the bamboo leaf frog to land on the simulation platform to form different slopes before continuing to shoot;

[0028] S7. Arrange the experimental data: After developing the taken photos, arrange the photos into a group of complete jumps, and record the arc of the bamboo leaf frog's jump at different starting heights and different landing surfaces, the maximum jump height, and the maximum jump distance.

[0029] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0030] 1. Adjustable take-off and landing points: The present invention can accurately adjust the take-off position of the bamboo leaf frog by lifting the adjustment member and the bamboo leaf frog take-off platform. Similarly, the bamboo leaf frog landing simulation platform can simulate different landing points to study the jumping performance of the bamboo leaf frog under different conditions.

[0031] 2. Slope simulation component: The present invention can simulate different terrain slopes. By adjusting the position and height of the driven gear and the simulation bump, a variety of complex jumping environments can be created, thereby providing a more comprehensive understanding of the jumping behavior of bamboo leaf frogs on different terrains.

[0032] 3. Motion camera and measurement auxiliary parts: The motion camera and measurement auxiliary parts of the present invention are used to record the jumping process of the bamboo leaf frog and assist researchers in accurate measurement and analysis. The motion camera can capture the movement trajectory of the bamboo leaf frog, and the measurement auxiliary parts provide a background board so that the photo can intuitively present the entire image, which is convenient for subsequent data processing and analysis.

[0033] 4. The main driving part of the present invention is the core part of the entire experimental platform. All moving parts are driven by a servo motor. This design allows researchers to easily adjust the operating state of the entire experimental platform by controlling the servo motor, thereby achieving rapid switching and setting of different experimental conditions.

[0034] By using this experimental platform, researchers can gain a deeper understanding of the bamboo leaf frog's jumping mechanism, influencing factors, and ability to adapt to different environments, especially uneven terrain, through distance measurement and photogrammetry. When faced with this type of actual terrain, the bamboo leaf frog's active jumping distance will be significantly affected by the movement trajectory and distance of the organism itself. This study can provide inspiration for the movement of the bamboo leaf frog, which is of great significance for protecting and studying the bamboo leaf frog, an important species in the ecosystem, and understanding its ecological functions and behavioral characteristics.

DETAILED DESCRIPTION

[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0052] Embodiment 1:

[0053] See also Figure 1 - Figure 8 In an embodiment of the present invention, a bamboo leaf frog jumping research platform includes a research operation platform 1, a lifting adjustment member 3 is rotatably connected to the research operation platform 1, a bamboo leaf frog take-off platform 9 for providing an initial standing position of the bamboo leaf frog is rotatably connected to the lifting adjustment member 3, a plurality of groups of slope simulation components 2 arranged in parallel are arranged at the bottom of the research operation platform 1, a bamboo leaf frog landing simulation platform 7 for providing a bamboo leaf frog landing position is arranged on the research operation platform 1, and the bamboo leaf frog landing simulation platform 7 is located above the plurality of slope simulation components 2, these main bodies are first installed on the research operation platform 1, and after installation, a preliminary prototype is realized as a whole, so that the bamboo leaf frog can jump from the bamboo leaf frog take-off platform 9 and finally land on the bamboo leaf frog landing simulation platform 7, so as to realize a jumping simulation;

[0054] Among them, a fourth support plate 16 is installed in front of the research operation platform 1, and a motion camera 17 is placed on the fourth support plate 16. A measurement auxiliary part 5 for assisting the motion camera 17 to shoot the motion trajectory of the bamboo leaf frog is set at the rear of the research operation platform 1. On the basis of the above-mentioned preliminary jump simulation, the motion camera 17 is added to shoot the motion image of the bamboo leaf frog, and the measurement auxiliary part 5 is to make a background plate for the motion camera 17, so that there is no need to manually change it to a line background later, so that the whole image can be intuitively seen in the photo;

[0055] During this shooting process, the distance between the measuring auxiliary member 5 and the motion camera 17 should ensure that no matter which grid the motion camera 17 is placed in on the fourth support plate 16, the entire bamboo leaf frog jumping scene can be shot, and the entire scene will not be unable to be shot due to the distance between the measuring auxiliary member 5 and the motion camera 17 being too close;

[0056] A main driving component 6 for driving the lifting and adjusting component 3 and multiple slope simulation components 2 to rotate is also installed at the bottom of the research operation platform 1. A central transmission rod 4 is also provided for driving the lifting and adjusting component 3 and the measuring auxiliary component 5. The main driving component 6 is the core part of the operation of the entire structure. The operation of the servo motor 61 in the main driving component 6 can drive multiple slope simulation components 2 independently, and can also drive the movement of the slope simulation component 2 and the lifting and lowering of the lifting and adjusting component 3 at the same time, so as to further drive the lifting and lowering of the bamboo leaf frog jumping platform 9 and the unfolding of the measuring auxiliary component 5 in linkage at the same time. In this way, the entire system can be operated by a main driving component 6, and the taking-off point of the bamboo leaf frog, the landing point of the bamboo leaf frog and the area of ​​the mesh curtain 51 unfolded for shooting can be adjusted.

[0057] The main driving member 6 includes a servo motor 61, the output shaft of the servo motor 61 is fixedly connected to a second threaded rod 62 through a coupling, a driving gear 63 is meshed at the bottom of the second threaded rod 62, a second driven rod 65 is arranged on the side of the driving gear 63 close to the slope simulation component 2, a first driven rod 64 is arranged on the other side of the driving gear 63, a first bevel gear is installed on the first driven rod 64, and the second driven rod 65 is meshed with the lifting adjustment member 3 through the first bevel gear;

[0058] It is worth noting that the surface of the first driven rod 64 near the end of the driving gear 63 and the interior of the driving gear 63 are both provided with mutually meshing ratchet gear rings 66. The above content shows all the operation modes of the main driving member 6. When the servo motor 61 is started, the driving gear 63 is driven to rotate through the second threaded rod 62. Regardless of the forward or reverse rotation, the second driven rod 65 will drive the multiple slope simulation components 2 to rotate. However, when the driving gear 63 is in Figure 7From the perspective of clockwise rotation, the ratchet tooth ring 66 of the driving gear 63 and the ratchet tooth ring 66 on the first driven rod 64 cannot be engaged, and only rotate along the teeth. In this way, the slope simulation component 2 can be adjusted separately. When simultaneous adjustments are required, it is only necessary to change the rotation direction of the servo motor 61, that is, to let the driving gear 63 rotate counterclockwise. At this time, the rotation of the driving gear 63 can not only drive the second driven rod 65 to rotate, but also drive the first driven rod 64 to rotate, that is, the slope simulation component 2, the lifting adjustment component 3, the bamboo leaf frog jumping platform 9 and the measurement auxiliary component 5 can be operated at the same time.

[0059] Among them, the slope simulation component 2 includes a fixed gear ring 21 and a center gear 25. The center gear 25 is arranged on the inner ring of the fixed gear ring 21. Four circumferentially distributed driven gears 23 are meshed on the center gear 25, and the four driven gears 23 are all meshed with the inner tooth surface of the fixed gear ring 21. Each driven gear 23 is installed with a simulation bump 24. Two positioning rods 22 are installed on the fixed gear ring 21. The fixed gear ring 21 is fixed to the bottom of the research operation platform 1 through the two positioning rods 22. The second driven rod 65 passes through multiple center gears 25 in sequence and is fixed to the axis of multiple center gears 25.

[0060] When the central gear 25 rotates, because the fixed gear ring 21 is fixed, the rotation of the central gear 25 drives the rotation of the driven gear 23. When the driven gear 23 rotates, due to the fixed gear ring 21, the driven gear 23 also moves in a circular motion with the central gear 25 as the center. In this way, the plurality of simulated protrusions 24 can be driven to rotate along the direction of their own rotation and can also revolve around the central gear 25 as the axis, thereby realizing multiple adjustments.

[0061] It is worth noting that in the attached drawings, we can clearly see that among the multiple simulation protrusions 24 of different shapes, one simulation protrusion 24 will eventually fit with the bamboo leaf frog landing simulation platform 7, and the simulation protrusions 24 of different shapes will push the bamboo leaf frog landing simulation platform 7 to different heights, so that the multiple slope simulation components 2 will eventually push the bamboo leaf frog landing simulation platform 7 to different heights, and finally make the bamboo leaf frog landing simulation platform 7 present an uneven slope surface;

[0062] Both ends of the bamboo leaf frog landing simulation platform 7 are connected to the research operation platform 1, and the above content is connected. This is to fix the two ends of the bamboo leaf frog landing simulation platform 7 with multiple slope simulation components 2, so that the slope surface as shown in the figure can be presented;

[0063] The lifting and lowering adjusting member 3 comprises a first threaded rod 31, a threaded sleeve 32 is threadedly connected to the surface of the first threaded rod 31, the surface of the threaded sleeve 32 is rotatably connected to the research and operation platform 1, a conical gear ring 33 is installed on the threaded sleeve 32, the threaded sleeve 32 is meshed with the main driving member 6 through the conical gear ring 33, a second conical gear is installed on the top of the first threaded rod 31, and third conical gears are installed at both ends of the central transmission rod 4, and the first threaded rod 31 is meshed with the adjacent third conical gear through the second conical gear;

[0064] Among them, a driving motor 34 is arranged at the bottom of the threaded sleeve 32, the output shaft of the driving motor 34 is fixed to the bottom of the first threaded rod 31 through a coupling, a lifting limit rod 35 is installed on the driving motor 34, and a third support plate 15 is installed at the bottom of the research operation platform 1, and the driving motor 34 is connected to the third support plate 15 by sliding up and down through the lifting limit rod 35;

[0065] The lifting and lowering adjusting member 3 is a receiving component that cooperates with the central transmission rod 4. The lifting and lowering adjusting member 3 can be driven by the first threaded rod 31, because the first driven rod 64 can only rotate counterclockwise under the action of the ratchet gear ring 66, that is, the threaded sleeve 32 can only be driven to rotate in one direction through the conical gear ring 33;

[0066] It is worth noting that when the conical gear ring 33 is driven by the first driven rod 64 to drive the threaded sleeve 32 to rotate, the first threaded rod 31 threadedly connected to the threaded sleeve 32 rotates to link the central transmission rod 4 to rotate and perform other operations. When the driving motor 34 starts automatically, the positioning plug 36 on the surface of the threaded sleeve 32 is first inserted into the positioning plug 37, and the positioning plug 37 is inserted into the surface of the research and operation platform 1, the threaded sleeve 32 is kept stationary, and the driving motor 34 drives the first threaded rod 31 to rotate. Under the limitation of the second support ring 14 on the central transmission rod 4 and the lifting limit rod 35 on the third support plate 15, the first threaded rod 31 itself can drive the bamboo leaf frog jumping platform 9 to rise or fall;

[0067] It is worth noting that the bamboo leaf frog take-off platform 9 itself is a lifting and adjusting member 3 that maintains a rotational connection relationship rather than a threaded connection. The rise and fall of the bamboo leaf frog take-off platform 9 depends on the rise and fall adjustment of the first threaded rod 31 itself. The rotational connection relationship between the bamboo leaf frog take-off platform 9 and the first threaded rod 31 can be connected by a bearing. The inner ring of the bearing is threadedly connected to the surface of the first threaded rod 31, while the outer ring is fixed to the bamboo leaf frog take-off platform 9. In this way, the rotation of the first threaded rod 31 itself will not affect the work of the bamboo leaf frog take-off platform 9. When you want to adjust the initial position of the bamboo leaf frog take-off platform 9 on the first threaded rod 31, you only need to clamp and fix the first threaded rod 31, and rotate the inner ring of the bearing. At this time, you only need to adjust the initial position of the bamboo leaf frog take-off platform 9.

[0068] The measurement auxiliary part 5 includes a rotating rod 52, a mesh curtain 51 is wound around the rotating rod 52, and the bottom end of the mesh curtain 51 is connected to the top of the research operation platform 1, and a fourth bevel gear is installed at one end of the rotating rod 52 close to the central transmission rod 4, and the rotating rod 52 is meshed with the adjacent third bevel gear through the fourth bevel gear;

[0069] Among them, two positioning rings 53 are installed on the rotating rod 52, and the two positioning rings 53 are respectively located on both sides of the mesh curtain 51;

[0070] A first support plate 11 is installed on the top of the research operation platform 1, a first limit slider 54 is fixedly installed on one end of the rotating rod 52 away from the central transmission rod 4, the first limit slider 54 is slidably connected to the first support plate 11, a first support ring 13 is installed on the rotating rod 52, a support tube 19 is installed on the top of the research operation platform 1, a sliding rod 18 is slidably connected to the top of the support tube 19, and the top of the sliding rod 18 is fixed to the first support ring 13;

[0071] The measuring auxiliary component 5 itself serves as a background plate for the shooting of the motion camera 17. The reason for unfolding the measuring auxiliary component 5 more is that when the bamboo leaf frog jumps higher on the bamboo leaf frog jumping platform 9, the mesh curtain 51 can also be unfolded more to ensure that the highest point of the bamboo leaf frog will not exceed the highest point of the unfolded mesh curtain 51. In this process, the driving of the measuring auxiliary component 5 only relies on the engagement between the rotating rod 52 and the central transmission rod 4, and the auxiliary support on one side is realized by the support tube 19 and the sliding rod 18 telescopically cooperating with the first support ring 13, while the other side is assisted by the sliding of the first limit slider 54 on the first support plate 11 to assist the support on the other side. In this way, it can be ensured that the measuring auxiliary component 5 can operate stably, and the role of the positioning ring 53 is to assist the mesh curtain 51 to keep it from rolling up when it is telescopically retracted and rolled up.

[0072] A second support plate 12 is installed on the side of the research operation platform 1, a bamboo leaf frog back baffle 8 is installed on the bamboo leaf frog take-off platform 9, a bamboo leaf frog take-off pad 91 is installed on the top of the bamboo leaf frog take-off platform 9, and a second limiting slider 92 is installed on the side of the bamboo leaf frog take-off platform 9 away from the bamboo leaf frog landing simulation platform 7, and the bamboo leaf frog take-off platform 9 is slidably connected to the second support plate 12 through the second limiting slider 92;

[0073] Furthermore, the bamboo leaf frog landing simulation platform 7 is made of Oxford cloth, which will form different slopes when the simulation protrusion 24 is lifted up.

[0074] A second support ring 14 is also slidably connected to the second support plate 12 . The second support ring 14 is rotatably connected to the central transmission rod 4 . The second support ring 14 is also fixed to the first support ring 13 .

[0075] The function of the bamboo leaf frog jumping platform 9 is to place the initial jumping point of the bamboo leaf frog. Adding the bamboo leaf frog back baffle 8 can prevent the bamboo leaf frog from jumping in the opposite direction, and adding the bamboo leaf frog jumping pad 91 can prevent the bamboo leaf frog from slipping when jumping and affecting the experimental results. Finally, the addition of the second support ring 14 can further stabilize the linkage operation between the lifting adjustment part 3, the central transmission rod 4 and the measurement auxiliary part 5, and the connection between the second support ring 14 and the first support ring 13 can allow the central transmission rod 4 to not only use the bevel gear to drive the measurement auxiliary part 5 to rotate, but also drive the measurement auxiliary part 5 to rise or fall.

[0076] Furthermore, multiple motion cameras 17 are placed, and motion cameras 17 with different shooting frame rates can be selected to minimize the difference in experimental data. Cameras with 10 frames per second, 20 frames per second, or other frame rates can be used, or frame-by-frame capture after shooting can be adopted.

[0077] Embodiment 2:

[0078] See also Fig. 9 , 10 The bamboo leaf frog landing simulation platform 7 includes a lifting seat 71, and landing limit blocks 72 are installed on both sides of the lifting seat. A landing limit rod 73 is installed on the research operation platform 1, and the lifting seat 71 is lifted and slid by the landing limit block 72 and the landing limit rod 73.

[0079] In this embodiment, other parts remain unchanged, except that the bamboo leaf frog landing simulation platform 7 is replaced with a plurality of lifting seats 71 that can be raised and lowered. The lifting seats are filled with water, and lotus leaves are placed on the water, so as to more vividly simulate the aquatic environment of the bamboo leaf frog. There is a corresponding slope simulation component 2 under each lifting seat 71 for contact operation, so that the environment and the landing point of the bamboo leaf frog when jumping can be more vividly simulated.

[0080] In summary, the advantages include:

[0081] 1. A variety of complex jumping environments can be created to more fully understand the jumping behavior of bamboo leaf frogs on different terrains;

[0082] 2. Assist researchers to conduct precise measurement and analysis.

[0083] 3. The operating status of the entire experimental platform can be easily adjusted by controlling the servo motor, thereby realizing rapid switching and setting of different experimental conditions.
