[0002] Animal population survey refers to the process of systematically observing and counting the quantity, distribution, structure, behavior, and survival status of a certain or multiple species of animals in a specific area through scientific methods. Its core objective is to obtain reliable population dynamics data to provide a basis for ecological research, species protection, and management decision-making.

Deploying infrared cameras requires a large amount of manpower for deployment and maintenance. During the deployment and maintenance process, a large number of human activities will be carried out in the living environment of the animal population.

[0021] Embodiment 1:

[0022] As Figure 1 shown, this embodiment provides an animal population survey device, which includes a support rod 1. A regulating mechanism 3 is connected to the support rod 1, and a plurality of auto-focus cameras 2 are connected to the regulating mechanism 3; The support rod 1 includes an embedded pipe section 11, a support pipe section 12, and a connecting pipe section 13. The embedded pipe section 11 is used to be embedded in the ground to form a base. The connecting pipe section 13 has a first connection state and a second connection state. When the connecting pipe section 13 is in the first connection state, the support pipe section 12 is inserted through the connecting pipe section 13, and the bottom end of the connecting pipe section 13 is hinged to the embedded pipe section 11; when the connecting pipe section 13 is in the second connection state, the support pipe section 12 is connected to the embedded pipe section 11, and the bottom of the connecting pipe section 13 is connected to the top of the support pipe section 12; The regulating mechanism 3 includes a lifting assembly 31 and an angle adjusting assembly 32. The lifting assembly 31 is connected through the connecting pipe section 13, and the angle adjusting assembly 32 is detachably connected to the lifting assembly 31; the angle adjusting assembly 32 is used to drive the auto-focus camera 2 to perform rotation angle adjustment and downward viewing angle adjustment, so that the auto-focus camera 2 can obtain image information of an annular survey range; the lifting assembly 31 is used to drive the auto-focus camera 2 to move to a set number of height positions, so that the auto-focus camera 2 can obtain image information of a plurality of adjacent annular survey ranges.

[0023] It can be understood that after determining the survey area of the animal population, an earth pit is excavated at the middle position of the survey area, the embedded pipe section 11 is embedded in the earth pit to form a base, and the gap between the embedded pipe section 11 and the earth pit is backfilled and compacted. Subsequently, the support pipe section is threaded through the connecting pipe section 13, and the bottom end of the connecting pipe section 13 is hinged to the embedded pipe section 11. When the connecting pipe section 13 forms a first connection state, by pushing the connecting pipe section 13, the connecting pipe section 13 deflects on the embedded pipe section 11 and then assumes a vertical state; then the support pipe section 12 is connected to the embedded pipe section 11, and the hinge between the connecting pipe section 13 and the embedded pipe section 11 is disassembled. After pushing the connecting pipe section 13 to slide within the support pipe section 12, the bottom of the connecting pipe section 13 is connected to the top of the support pipe section 12, and the connecting pipe section 13 forms a second connection state; after the connecting pipe section 13 is in the second connection state, the angle adjustment component 32 is connected to the lifting component 31. During the investigation of the animal population, the angle adjustment component 32 drives the multiple auto-focus cameras 2 to adjust the rotation angle. Through the cooperation of the multiple auto-focus cameras 2, the image information of the annular survey range is obtained; the angle adjustment component 32 drives the multiple auto-focus cameras 2 to adjust the top-down angle, so that the width of the annular survey range obtained at the current height position increases; after the image information of the current annular survey range is obtained, the lifting component 31 drives the multiple auto-focus cameras 2 to rise or fall to the next set height position. When the top-down angle adjustment range of the auto-focus camera 2 remains unchanged and the height position of the auto-focus camera 2 changes, the radius of the annular survey range obtained by the auto-focus camera 2 increases or decreases. After the lifting component 31 drives the auto-focus camera 2 to rise or fall to the next set height position, the current obtained annular survey range is closely adjacent to the annular survey range obtained at the previous height position. The lifting component 31 drives the multiple auto-focus cameras 2 to gradually rise or fall to the set multiple height positions, and the image information of multiple adjacent annular survey ranges is obtained, so as to realize the investigation of the animal population. The angle adjustment component 32 cooperates with the lifting component 31 to run multiple times step by step, and the survey area is repeatedly surveyed multiple times. After the survey period ends, it is gradually disassembled and evacuated; in this technical solution, the support rod 1 is connected by the embedded pipe section 11, the support pipe section 12 and the connecting pipe section 13, and the survey point can be quickly built in the living environment of the animal population. The angle adjustment component 32 drives the auto-focus camera 2 to adjust the rotation angle and the top-down angle, and the image information of the annular survey range is obtained. The lifting component 31 drives the auto-focus camera 2 to move to the set multiple height positions, and the image information of multiple adjacent annular survey ranges is obtained, so as to realize large-scale survey in the living environment of the animal population through a single survey point, reduce human activities and improve the coverage of the survey range.

[0024] Such asFigure 2 As shown, the embedded pipe section 11 is provided with a plurality of limiting openings 111 penetrating therethrough. An embedded plate 112 is hinged in the limiting opening 111. After the embedded pipe section 11 is embedded into the ground, the embedded plate 112 is located inside the embedded pipe section 11. An internally threaded pipe is installed inside the embedded pipe section 11. The internally threaded pipe is threadedly connected to a threaded rod. The top end of the threaded rod is integrally provided with a docking column 113. The bottom of the docking column 113 is provided with a tapered section. The docking column 113 is used to squeeze the embedded plate 112 to deflect outside the embedded pipe section 11, so that the embedded plate 112 is embedded into the soil.

[0025] It can be understood that after the embedded pipe section 11 is embedded into the ground, under the weight of the support pipe section 12, the connecting pipe section 13 and the adjusting mechanism 3, there is a risk of the embedded pipe section 11 tipping over; therefore, a plurality of limiting openings 111 are penetrated and opened in the embedded pipe section 11, and the embedded plate 112 is hinged in the limiting opening 111. After the embedded pipe section 11 is embedded into the ground, the embedded plate 112 is located inside the embedded pipe section 11; after the embedded pipe section 11 is embedded into the ground, the threaded rod is then connected to the internally threaded pipe, so that the docking column 113 moves up and down inside the embedded pipe section 11. During the process of the docking column 113 moving up and down inside the embedded pipe section 11, the tapered section at the bottom of the docking column 113 gradually pushes the embedded plate 112 outside the embedded pipe section 11, so that the embedded plate 112 is embedded into the soil. After the threaded rod and the internally threaded pipe are connected in place, the docking column 113 abuts and supports the plurality of embedded plates 112, limiting the plurality of embedded plates 112 outside the embedded pipe section 11. The plurality of embedded plates 112 are embedded into the soil to form multi-point support for the embedded pipe section 11, increasing the connection area between the embedded pipe section 11 and the soil, thereby enhancing the anti-tipping performance of the embedded pipe section 11.

[0026] As Figures 2 - 4 shown, the top end of the docking column 113 is integrally provided with an adjusting ear plate 114. The adjusting ear plate 114 is penetrated and connected with a connecting rod 115. The connecting rod 115 drives the docking column 113 to rotate through the adjusting ear plate 114. The bottom end of the connecting pipe section 13 is integrally provided with a U-shaped ear plate 131. When the connecting pipe section 13 is in the first connection state, the connecting rod 115 is penetrated and hinged inside the adjusting ear plate 114 and the U-shaped ear plate 131. A bayonet 121 is opened at the bottom end of the support pipe section 12. After the support pipe section 12 is connected to the embedded pipe section 11, the connecting rod 115 is disassembled and taken out from the bayonet 121.

[0027] It can be understood that after the threaded rod is connected to the internal threaded pipe in place, the support pipe section 12 is sleeved on the connecting pipe section 13, and the connecting rod 115 is sleeved in the adjusting ear plate 114 and the U-shaped ear plate 131 for hinging, so that the connecting pipe section 13 is in the first connection state. By hinging the adjusting ear plate 114 and the U-shaped ear plate 131, it is convenient for the staff to push and deflect the connecting pipe section 13 from the horizontal state to the vertical state. After the connecting pipe section 13 is pushed and deflected to the vertical state, the support pipe section 12 is connected to the embedded pipe section 11, so that the support pipe section 12 restricts the connecting pipe section 13 to remain in the vertical state. Subsequently, the connecting rod 115 is removed from the bayonet 121, and the connection between the adjusting ear plate 114 and the U-shaped ear plate 131 is separated. After pushing the connecting pipe section 13 to slide in the support pipe section 12, the bottom of the connecting pipe section 13 is connected to the top of the support pipe section 12, and the connecting pipe section 13 forms the second connection state.

[0028] As Figure 3 shown, two wire grooves are symmetrically opened on the inner wall of the support pipe section 12. A steel cable 122 is arranged in a U shape in the support pipe section 12. The steel cable 122 is located in the wire grooves. One end of the steel cable 122 is fixedly connected to the support pipe section 12. A fixed pulley 132 is connected to the bottom end of the connecting pipe section 13. A pulley block 123 and a winch 124 are connected to the outer wall of the support pipe section 12. The steel cable 122 is wound around the fixed pulley 132 and the pulley block 123. The other end of the steel cable 122 is in transmission connection with the winch 124. The steel cable 122 is used to drive the connecting pipe section 13 to slide in the support pipe section 12, which is convenient for the connecting pipe section 13 to be converted between the first connection state and the second connection state.

[0029] It can be understood that during the installation process, when the connecting pipe section 13 is converted from the first connection state to the second connection state, the height of the support pipe section 12 and the weight of the connecting pipe section 13 make it difficult to push and slide the connecting pipe section 13 upward within the support pipe section 12; during the disassembly process, when the connecting pipe section 13 is converted from the second connection state to the first connection state, after disassembling the connection between the bottom of the connecting pipe section 13 and the top of the support pipe section 12, the connecting pipe section 13 will quickly slide down within the support pipe section 12, and the huge impact force will cause component damage and safety accidents; therefore, a steel cable 122 is arranged within the support pipe section 12, and the connecting pipe section 13 is connected to the steel cable 122 through a fixed pulley 132, and the length of the steel cable 122 within the support pipe section 12 is adjusted through the cooperation of a pulley block 123 and a winch 124; when the connecting pipe section 13 is converted from the first connection state to the second connection state, the winch 124 cooperates with the pulley block 123 to wind up the steel cable 122 within the support pipe section 12, so that the steel cable 122 drives the connecting pipe section 13 to slide upward within the support pipe section 12 through the fixed pulley 132 until the bottom connection position of the connecting pipe section 13 is adapted to the top position of the support pipe section 12; when the connecting pipe section 13 is converted from the second connection state to the first connection state, after disassembling the connection between the bottom of the connecting pipe section 13 and the top of the support pipe section 12, the winch 124 cooperates with the pulley block 123 to unwind the steel cable 122, so that the steel cable 122 drives the connecting pipe section 13 to slide downward within the support pipe section 12 through the fixed pulley 132 until the connection position between the adjusting ear plate 114 and the U-shaped ear plate 131 corresponds to each other.

[0030] As Figures 2 - 4 shown, the embedded pipe section 11 is integrally provided with a limiting ring plate 116, and a butt joint cylinder 117 is integrally provided on the limiting ring plate 116, and the support pipe section 12 is connected within the butt joint cylinder 117 through a plurality of first bolts 118; A plurality of guide grooves are formed on the inner wall of the support pipe section 12, and a plurality of guide strips 133 are integrally provided on the outer wall of the bottom of the connecting pipe section 13, and the guide strips 133 are slidably connected to the guide grooves, and the top of the support pipe section 12 is connected to the guide strips 133 through a plurality of second bolts 134.

[0031] It can be understood that the limiting ring plate 116 can limit the depth of the embedded pipe section 11 embedded in the ground. At the same time, after the limiting ring plate 116 abuts against the ground, the anti-tipping performance of the embedded pipe section 11 can be enhanced. The support pipe section 12 is connected in the docking cylinder 117 through a plurality of first bolts 118, which facilitates connection or disassembly while ensuring connection stability; the sliding connection between the guiding strip 133 and the guiding groove restricts the connection pipe section 13 to only slide directionally within the support pipe section 12, so as to ensure that the connection position of the connection pipe section 13 corresponds to that of the support pipe section 12, and the connection position of the adjusting ear plate 114 corresponds to that of the U-shaped ear plate 131. By means of connection through the second bolt 134, it is convenient to connect or disassemble the connection pipe section 13 and the support pipe section 12.

[0032] As Figures 5 - 6 shown, the lifting assembly 31 includes a servo motor 311, a lead screw 312 and a connecting column 313. The lead screw 312 is rotatably connected within the connecting pipe section 13. The servo motor 311 is drivingly connected to the lead screw 312. The connecting column 313 is threadedly connected to the lead screw 312. The lead screw 312 is used to drive the connecting column 313 to move to a set number of height positions, so as to increase or decrease the radius of the annular survey range of the auto-zoom camera 2; A plurality of waist-shaped holes 135 are formed in the connecting pipe section 13. A support bar 314 is inserted through the waist-shaped holes 135. One end of the support bar 314 is snap-connected to the connecting column 313, and the other end of the support bar 314 is detachably connected to the angle adjustment assembly 32.

[0033] It can be understood that after the connecting pipe section 13 is in the second connection state, the support bar 314 is inserted into the waist-shaped hole 135 and snap-connected to the connecting column 313, and then the angle adjustment assembly 32 is connected to the support bar 314; the servo motor 311 is used to drive the lead screw 312 to rotate clockwise or counterclockwise by a set number of turns. After the lead screw 312 rotates clockwise or counterclockwise by a set number of turns, it drives the connecting column 313 to slide within the connecting pipe section 13 to a set height position, so that the auto-zoom camera 2 is adjusted to the corresponding height position, so as to increase or decrease the radius of the annular survey range of the auto-zoom camera 2.

[0034] As Figures 6 - 7 shown, the angle adjustment assembly 32 includes a positioning ring plate 321 and an adjustment ring plate 322. The positioning ring plate 321 is connected to the support bar 314 through a third bolt. The adjustment ring plate 322 is rotatably connected below the positioning ring plate 321; A plurality of arc-shaped holes 323 are formed through the adjusting ring plate 322. A plurality of positioning columns are integrally provided on the positioning ring plate 321. The positioning columns are inserted into the arc-shaped holes 323. A first electric cylinder 324 is hinged on the positioning columns. The first electric cylinder 324 is in transmission connection with the adjusting ring plate 322. The first electric cylinder 324 is used to drive the adjusting ring plate 322 to adjust the rotation angle, so that the automatic zoom camera 2 obtains image information of an annular survey range. A plurality of U-shaped seats 325 are symmetrically connected to the adjusting ring plate 322. An adjusting plate 326 is hinged in the U-shaped seats 325. The automatic zoom camera 2 is connected to the adjusting plate 326. A plurality of second electric cylinders 327 are hinged on the adjusting ring plate 322. The second electric cylinders 327 are in transmission connection with the adjusting plate 326. The second electric cylinders 327 are used to drive the automatic zoom camera 2 to adjust the overlooking angle, so that the width of the annular survey range of the automatic zoom camera 2 is increased.

[0035] It can be understood that after the support bar 314 passes through the kidney-shaped hole 135 and is snap-connected to the connecting column 313, the positioning ring plate 321 is connected to the support bar 314 through a third bolt. When adjusting the rotation angle, the first electric cylinder 324 drives the adjusting ring plate 322 to rotate or reset by a set rotation angle, so that the automatic zoom camera 2 obtains perspectives at different rotation angles. The perspectives at a plurality of different rotation angles are combined to obtain image information of the annular survey range. When adjusting the overlooking angle, the second electric cylinder 327 drives the adjusting plate 326 to adjust or reset by a set elevation angle. The second electric cylinder 327 has a plurality of stroke lengths, so that the overlooking angle of the automatic zoom camera 2 is gradually changed. The overlooking angle of the automatic zoom camera 2 adjusted by the second electric cylinder 327 is gradually changed between 30° and 60°. The plurality of strokes of the second electric cylinder 327 adjust the overlooking angle adjusted each time by the automatic zoom camera 2 to be 5°-10°, so that the width of the annular survey range of the automatic zoom camera 2 is increased.

[0036] As Figure 8 shown, a pushing assembly 4 is provided on the embedded pipe section 11. The pushing assembly 4 includes a T-shaped bottom plate 41, a translation device 42 and a push rod 43. A T-shaped card slot 119 is integrally provided on the limiting ring plate 116. The head of the T-shaped bottom plate 41 is connected in the T-shaped card slot 119 through a fourth bolt 44. The translation device 42 is connected to the tail of the T-shaped bottom plate 41. A push ear plate is connected to the moving seat of the translation device 42. One end of the push rod 43 is hinged to the push ear plate through a fifth bolt. A support ear plate is connected to the support pipe section 12. The other end of the push rod 43 is hinged to the support ear plate through a sixth bolt.

[0037] It is understandable that when the connecting pipe section 13 is in the first connection state, it is difficult for the staff to push the connecting pipe section 13 from the horizontal state to the vertical state, and there is a high risk in the pushing process; therefore, a pushing component 4 is set on the embedded pipe section 11. After the connecting pipe section 13 is in the first connection state, the staff erects the connecting pipe section 13 to an inclined state, slides the supporting pipe section 12 to the bottom of the connecting pipe section 13, and then connects the T-shaped bottom plate 41 to the T-shaped slot 119 through the fourth bolt 44, and then hinges one end of the pushing rod 43 to the supporting ear plate through the sixth bolt, and after adjusting the moving seat of the translation device 42, the other end of the pushing rod 43 is pushed The fifth bolt is hinged to the push ear plate, and then the translation device 42 is driven to push and deflect the connecting pipe section 13 from the inclined state to the vertical state through the push rod 43, and then the supporting pipe section 12 is connected to the embedded pipe section 11, so that the supporting pipe section 12 restricts the connecting pipe section 13 to remain in the vertical state; similarly, when disassembling, the translation device 42 cooperates with the push rod 43 to slowly deflect the connecting pipe section 13 from the vertical state to the inclined state, and after supporting and erecting the connecting pipe section 13 in the inclined state, the push rod 43 and the translation device 42 are gradually disassembled; thereby reducing the difficulty of installation or disassembly and avoiding risks during installation or disassembly.
