Description

Technical Field

[0001] This invention relates to the field of animal survey and monitoring technology, and more specifically, to an observation device and method for monitoring the breeding of wild crested ibises. Background Technology

[0002] The crested ibis is a Class I protected wild animal in my country. Wild crested ibis populations used to primarily nest in the low-to-medium altitude mountainous areas of Yangxian County, with Masson pine as their main nesting tree species. The average nest height was about 13 meters. Surveyors typically had to climb the trees directly or reach a high point on the hillside parallel to the nest to observe the number of eggs in the nest from a distance using binoculars—a process that was extremely time-consuming and laborious. After 2004, wild crested ibis populations gradually began to spread to the Hanzhong Plain. By 2018, the proportion of nest sites in the plains had exceeded that in the mountains. In the plains, the main nesting tree species are poplar and elm, which have thicker trunks and result in even higher nests (around 15 meters). Due to the flat terrain, traditional survey methods were impossible, forcing the interruption of long-term monitoring of nest numbers. This resulted in a lack of crucial data support for crested ibis research and theoretical innovation.

[0003] However, due to a lack of effective technical equipment and methods, monitoring of released crested ibises in various regions is extremely inadequate, and important parameters such as breeding success rates are unclear. This makes it difficult to assess the effectiveness of releases and to formulate targeted protection and management strategies, posing a significant challenge to the survival and development of released populations. Therefore, effectively investigating breeding conditions such as nest size is a technical challenge in establishing a self-sustaining crested ibis release population. Furthermore, for other birds nesting in tall trees, investigating breeding parameters is also a technical bottleneck for conservation and research. Some researchers have used large mechanical equipment such as aerial tramways, but this method causes significant disturbance to birds, is costly, and is greatly limited by terrain and road conditions. Summary of the Invention

[0004] To address the above problems, this invention provides an observation device and method for monitoring the breeding of wild crested ibises.

[0005] In a first aspect, the present invention provides an observation device for monitoring the breeding of wild crested ibises, comprising:

[0006] Multi-stage telescopic rod, with a maximum and minimum section;

[0007] The exploration mechanism includes an arc-shaped elastic rod and a miniature ultra-high-definition camera lens. One end of the arc-shaped elastic rod is detachably connected to the smallest cylindrical section, and the other end of the arc-shaped elastic rod extends off-axis from the multi-stage telescopic rod. The miniature ultra-high-definition camera lens is built into the other end of the arc-shaped elastic rod.

[0008] Optionally, the end of the arc-shaped elastic rod furthest from the smallest cylindrical section is designated as the projectile end.

[0009] Optionally, the arc-shaped elastic rod contains a secondary transmission line, one end of which is electrically connected to the miniature ultra-high-definition camera lens. A plug is located at the end of the arc-shaped elastic rod furthest from the miniature ultra-high-definition camera lens. A socket is located at the end of the smallest cylindrical section. A main transmission line is located within the smallest cylindrical section. A controller is located within the largest cylindrical section. The other end of the secondary transmission line is electrically connected to the plug, which is used to connect to the socket. The socket is electrically connected to one end of the main transmission line, and the other end of the main transmission line is electrically connected to the controller.

[0010] Optionally, the inner bottom of the largest section is provided with a winding mechanism, and the main transmission line is connected to the winding mechanism so that the main transmission line can be wound on the winding mechanism as the smallest section moves.

[0011] Optionally, the winding mechanism includes a measuring tape spring and a housing, the housing being connected to the bottom of the largest cylindrical section, the measuring tape spring having a concave arc surface and a convex arc surface, and the main transmission line being connected to the concave arc surface.

[0012] Optionally, the observation device for monitoring the breeding of wild crested ibises further includes a counterweight cylinder, a counterweight block, and an adaptive adjustment mechanism. The counterweight cylinder is connected to the largest cylinder section and is parallel to the largest cylinder section. The counterweight block is slidably connected inside the counterweight cylinder. The adaptive adjustment mechanism is located on the counterweight cylinder and the largest cylinder section. When the smallest cylinder section is pulled out a greater distance, the counterweight cylinder is closer to the bottom of the counterweight cylinder.

[0013] Optionally, the adaptive adjustment mechanism includes a first winding component and a second winding component. The first winding component is driven to the measuring tape spring, the first winding component is driven to the second winding component, and the second winding component is driven to the counterweight block, so that when the measuring tape spring is released, the counterweight block slides toward the bottom of the counterweight cylinder.

[0014] Optionally, the measuring tape spring has continuous teeth on its convex surface, and the teeth are driven to connect with the first winding component.

[0015] Optionally, a mobile phone holder is connected to the largest cylindrical section.

[0016] Secondly, embodiments of the present invention also provide an observation method based on the observation equipment for monitoring the breeding of wild crested ibises as described above, comprising the following steps:

[0017] S1: After carrying the equipment to the nest tree, connect the curved elastic rod to the smallest section, and at the same time turn on the miniature ultra-high-definition camera lens, connect it to the smartphone via WIFI hotspot and synchronize the video stream;

[0018] S2: Press the bottom of the largest tube section firmly against the ground at the base of the nest tree, and extend the curved elastic rod upwards until the miniature ultra-high-definition camera lens is higher than the bird's nest;

[0019] S3: Observe through a smartphone and adjust the position of the miniature ultra-high-definition camera lens by rotating or raising / lowering the multi-stage telescopic rod according to the field of view to find the best shooting angle;

[0020] S4: After observing a clear view of the nest, remain still and record the number of eggs, the number of hatched chicks, the growth of the chicks' feathers, and other breeding conditions in the nest, while taking photos or videos.

[0021] S5: After observation, rotate the curved elastic rod to face away from the nest to prevent it from getting caught on the edge of the nest when retracting the rod. Retract the rod section by section.

[0022] S6: Turn off the power, remove the curved elastic rods, put them into the storage bags, and leave the nest site as soon as possible.

[0023] The beneficial effects of the observation device for monitoring the breeding of wild crested ibises of this invention are as follows: the overall length can be changed by pulling and extending the multi-stage telescopic rod to adapt to nests of different heights; the arc-shaped elastic rod and the smallest cylindrical section are designed to be detachably connected to facilitate the carrying of the exploration mechanism in the field; and the arc-shaped elastic rod is set to extend off the axis of the multi-stage telescopic rod, which on the one hand allows the miniature ultra-high-definition camera lens to capture a panoramic view of the nest without directly contacting it; on the other hand, the arc-shaped elastic rod has a certain degree of elasticity, which allows it to move more smoothly among the branches and leaves, greatly reducing human interference and the risk of damage to the nest.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0033] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0034] This invention provides an observation device for monitoring the breeding of wild crested ibises, comprising:

[0035] The multi-stage telescopic rod 1 has a maximum section 11 and a minimum section 12;

[0036] The exploration mechanism 2 includes an arc-shaped elastic rod 21 and a miniature ultra-high-definition camera lens 22. One end of the arc-shaped elastic rod 21 is detachably connected to the smallest cylindrical section 12, and the other end of the arc-shaped elastic rod 21 extends off-axis from the multi-stage telescopic rod 1. The miniature ultra-high-definition camera lens 22 is built into the other end of the arc-shaped elastic rod 21.

[0037] Specifically, in combination Figure 1 and Figure 2 As shown, the multi-stage telescopic rod 1 is composed of multiple nested sections with progressively decreasing diameters, including the thickest largest section 11 and the thinnest smallest section 12. The largest section 11 is the handle, and the smallest section 12 is the top section. The overall length can be changed by pulling it to accommodate bird nests of different heights. One end of the curved elastic rod 21 can be detachably connected to the end of the smallest section 12 via threads, snaps, or magnets. It is elastic and can deform and recover upon slight impact, preventing damage to the bird nest or itself from hard impacts. A miniature ultra-high-definition camera lens 22 is embedded in the other end of the curved elastic rod 21. Its lens direction is pre-adjusted to ensure that when the multi-stage telescopic rod 1 is raised, the lens is directly facing the bird nest below. The miniature ultra-high-definition camera lens 22 has high-definition video recording and photo taking functions and integrates a WIFI module for wireless video streaming.

[0038] In this optional embodiment, the overall length is changed by pulling the multi-stage telescopic rod 1 to adapt to bird nests of different heights. The arc-shaped elastic rod 21 is detachably connected to the smallest cylindrical section 12 to facilitate the carrying of the exploration mechanism 2 in the field. Furthermore, the arc-shaped elastic rod 21 is extended off-axis from the multi-stage telescopic rod 1. On the one hand, it allows the miniature ultra-high-definition camera lens 22 to capture a panoramic view of the nest without directly contacting it. On the other hand, the arc-shaped elastic rod 21 has a certain degree of elasticity, which allows it to move more smoothly among the branches and leaves, greatly reducing human interference and the risk of damage to the bird nest.

[0039] Optionally, the end of the arc-shaped elastic rod 21 furthest from the minimum cylinder section 12 is designated as the projectile end 211.

[0040] In this optional embodiment, the end of the arc-shaped elastic rod 21 furthest from the smallest cylindrical section 12 is designed as the projectile end 211. The projectile end 211 can be a smooth, streamlined hemispherical or ellipsoidal structure that wraps around and protects the internal miniature ultra-high-definition camera lens 22. Its surface is very smooth, which can effectively prevent the arc-shaped elastic rod 21 from hooking onto tree branches, bird nests or wires during the lifting process, greatly improving the smoothness and safety of operation. Even if it collides with branches and leaves, the streamlined design of the arc-shaped elastic rod 21 can make it slip off rather than hook.

[0041] Furthermore, the arc-shaped elastic rod 21 is provided with a secondary transmission line. One end of the secondary transmission line is electrically connected to the miniature ultra-high-definition camera lens 22. The end of the arc-shaped elastic rod 21 away from the miniature ultra-high-definition camera lens 22 is provided with a plug. The end of the smallest cylindrical section 12 is provided with a socket. The smallest cylindrical section 12 is provided with a main transmission line 33. The largest cylindrical section 11 is provided with a controller 32. The other end of the secondary transmission line is electrically connected to the plug. The plug is used to connect to the socket. The socket is electrically connected to one end of the main transmission line 33. The other end of the main transmission line 33 is electrically connected to the controller 32.

[0042] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, a secondary transmission line is pre-embedded within the arc-shaped elastic rod 21. One end of the secondary transmission line connects to the miniature ultra-high-definition camera lens 22, and the other end terminates at a plug. The plug is exposed at the connection end of the arc-shaped elastic rod 21. At the end of the smallest cylindrical section 12, a socket matching the aforementioned plug is provided. A main transmission line 33 is arranged in the internal cavity of the smallest cylindrical section 12. One end of the main transmission line 33 connects to the socket, and the other end passes downward through all the cylindrical sections, finally connecting to the controller 32 located inside the largest cylindrical section 11. The controller 32 can be an integrated circuit board containing a battery, a power management module, a WIFI transmitter, etc., used to power the miniature ultra-high-definition camera lens 22 and receive and forward its signals, thereby realizing a quick electrical connection between the miniature ultra-high-definition camera lens 22 and the smallest cylindrical section 12. In the field, a simple plug-in connection is all that is needed to simultaneously complete mechanical fixation and power supply, simplifying the operation process. Furthermore, the secondary transmission line and the main transmission line 33 are built-in, avoiding the problems of exposed cables being easily tangled and damaged.

[0043] Optionally, the inner bottom of the largest section 11 is provided with a winding mechanism 3, and the main transmission line 33 is connected to the winding mechanism 3 so that the main transmission line 33 can be wound on the winding mechanism 3 as the smallest section 12 moves.

[0044] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, by setting a winding mechanism 3 at the bottom inner part of the largest cylindrical section 11, the main transmission line 33 is not loosely placed inside the pole, but its end is fixed and wound around a winding mechanism 3, which has an automatic winding function. When the telescopic pole extends, the winding mechanism 3 releases the main transmission line 33; when the telescopic pole retracts, the winding mechanism 3 automatically winds the main transmission line 33 back, ensuring that the cable length can adapt to the change in pole length and is always in a taut state. This completely avoids the risk of the cable getting tangled, piled up, or knotted inside the pole, greatly improving the reliability and durability of the equipment.

[0045] Furthermore, the winding mechanism 3 includes a measuring tape spring 31 and a housing 34. The housing 34 is connected to the bottom of the largest cylindrical section 11. The measuring tape spring 31 has a concave arc surface and a convex arc surface, and the main transmission line 33 is connected to the concave arc surface.

[0046] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, the specific structure of the winding mechanism 3 consists of a measuring tape spring 31 and a housing 34. The housing 34 can be a circular or square box fixed to the bottom of the largest section 11. The measuring tape spring 31 can be an elastic, coiled steel strip or composite material strip with an arc-shaped cross-section, having concave and convex arc surfaces, similar to a steel measuring tape. The main transmission line 33 is fixed to its concave arc surface by means of clips or adhesive. When the smallest section 12 is pulled out, the main transmission line 33 is pulled, causing the measuring tape spring 31 to unfold and deform (release). When released, the elastic restoring force of the measuring tape spring 31 will drive it to automatically rewind, thereby winding up the main transmission line 33. By adopting the measuring tape spring 31 structure, purely mechanical, unpowered automatic cable management is achieved. The structure is simple, highly reliable, and requires no power drive, making it very suitable for use in field environments.

[0047] Optionally, the observation equipment for monitoring the breeding of wild crested ibises also includes a counterweight cylinder 4, a counterweight block 5, and an adaptive adjustment mechanism 6. The counterweight cylinder 4 is connected to the largest cylinder section 11 and is parallel to the largest cylinder section 11. The counterweight block 5 is slidably connected inside the counterweight cylinder 4. The adaptive adjustment mechanism 6 is located on the counterweight cylinder 4 and the largest cylinder section 11. When the smallest cylinder section 12 is pulled out a greater distance, the counterweight cylinder 4 is closer to the bottom of the counterweight cylinder 4.

[0048] In this optional embodiment, combined with Figure 3 , Figure 4 and Figure 5 As shown, the counterweight cylinder 4 is a cylindrical tube fixed parallel to the largest cylinder section 11, and the upper part of the counterweight cylinder 4 can be partitioned to accommodate the arc-shaped elastic rod 21 and the miniature ultra-high-definition camera lens 22. The counterweight block 5 can be a heavy object made of high-density material (such as brass or lead blocks), whose shape matches the inner wall of the counterweight cylinder 4 and can slide up and down along the inner wall of the cylinder. When the smallest cylinder section 12 is pulled out (the rod becomes longer), the mechanism drives the counterweight block 5 to move to the bottom of the counterweight cylinder 4. When the smallest cylinder section 12 is retracted, the counterweight block 5 is pulled back to the top. In other words, the longer the multi-stage telescopic rod 1 extends, the higher the center of gravity and the more violent the shaking. At this time, the counterweight block 5 moves down, thereby lowering the center of gravity of the multi-stage telescopic rod 1 as a whole, significantly enhancing wind resistance and stability, and improving the stability of the top miniature ultra-high-definition camera lens 22 during observation.

[0049] Furthermore, the adaptive adjustment mechanism 6 includes a first winding component 61 and a second winding component 62. The first winding component 61 is driven to be connected to the measuring tape spring 31, the first winding component 61 is driven to be connected to the second winding component 62, and the second winding component 62 is driven to be connected to the counterweight 5, so that when the measuring tape spring 31 is released, the counterweight 5 slides toward the bottom of the counterweight cylinder 4.

[0050] Optionally, the measuring tape spring 31 has continuous teeth 311 on its convex arc surface, and the teeth 311 are driven to be connected to the first winding component 61.

[0051] In this optional embodiment, combined with Figure 3 , Figure 4 and Figure 5 As shown, the adaptive adjustment mechanism 6 consists of a first winding component 61, a second winding component 62, and a steel wire. The first winding component 61 consists of a first rotating shaft, a first gear, a first reel, and a first steel wire. The second winding component 62 consists of a second rotating shaft, a second gear, a second reel, a second steel wire, a third gear, and a third rotating shaft. The two ends of the first steel wire are respectively wound around the first reel and the second reel. When the measuring tape spring 31 is released or retracted, the continuous teeth 311 become vertical, driving the first gear and the first reel to rotate. This, in turn, drives the second gear and the second reel to rotate via the first steel wire, and then drives the third gear and the first reel to rotate. The third shaft rotates, and one end of the second steel wire is wound around the third shaft. The other end of the second steel wire is connected to the counterweight 5. When the multi-stage telescopic rod 1 extends and the measuring tape spring 31 is released, the steel wire is released, and the counterweight 5 slides down naturally under the action of gravity. When the multi-stage telescopic rod 1 retracts and the measuring tape spring 31 retracts, the counterweight 5 is lifted and reset. In other words, in the initial state, the smallest cylinder section 12 is completely retracted into the largest cylinder section 11, and the measuring tape spring 31 is in the maximum winding state, storing elastic potential energy, which makes the counterweight 5 lifted and suspended in the middle of the counterweight cylinder 4, thereby making the center of gravity central, which is convenient for carrying and transportation. When the operator begins to pull out the smallest section 12 during operation, the main transmission line 33 is pulled out, causing the measuring tape spring 31 to release (unfold). The release process of the measuring tape spring 31 is a process of weakening its stored elastic potential energy. The unfolding motion (linear motion) of the measuring tape spring 31, through the continuous teeth 311 on its convex arc surface, and through the first winding component 61 and the second winding component 62, causes the counterweight 5 to begin to slide smoothly downward along the inner wall of the counterweight cylinder 4 under its own weight. In other words, the longer the multi-stage telescopic rod 1 is pulled out, the more the measuring tape spring 31 is released, and the lower the position of the counterweight 5 as it slides down. As the rod body rises and the risk of swaying increases, the counterweight 5 descends synchronously, effectively pulling the overall center of gravity of the multi-stage telescopic rod 1 downward, significantly enhancing the stability of the equipment and suppressing the swaying of the arc-shaped elastic rod 21.

[0052] Furthermore, a mobile phone holder 7 is connected to the largest cylindrical section 11.

[0053] In this optional embodiment, combined with Figure 1 and Figure 3 As shown, a mobile phone holder 7 is connected to the largest cylindrical section 11. The mobile phone holder 7 can be fixed to the largest cylindrical section 11 by clamping or magnetic attraction. The position is convenient for the operator to view, and the investigator can fix the smartphone on the mobile phone holder 7 and use it directly as a monitor. This frees up the operator's hands, allowing them to focus more on and operate the multi-stage telescopic rod 1 more stably, while avoiding the shaking and errors that may be caused by holding a smartphone, thus improving observation efficiency.

[0054] This invention also provides an observation method based on the above-mentioned observation equipment for monitoring the breeding of wild crested ibises, comprising the following steps:

[0055] S1: After carrying the equipment to the nest tree, connect the arc-shaped elastic rod 21 to the smallest cylindrical section 12, and at the same time turn on the miniature ultra-high-definition camera lens 22 to connect to the smartphone via WIFI hotspot and synchronize the video stream;

[0056] S2: Press the bottom of the largest tube section 11 tightly against the ground at the base of the nest tree, and extend the curved elastic rod 21 upwards until the miniature ultra-high-definition camera lens 22 is higher than the bird's nest;

[0057] S3: Observe through a smartphone and rotate or raise / lower the multi-stage telescopic rod 1 as needed to adjust the position of the miniature ultra-high-definition camera lens 22 to find the best shooting angle;

[0058] S4: After observing a clear view of the nest, remain still and record the number of eggs, the number of hatched chicks, the growth of the chicks' feathers, and other breeding conditions in the nest, while taking photos or videos.

[0059] S5: After observation, rotate the curved elastic rod 21 to face away from the nest to prevent it from getting caught on the edge of the nest when retracting the rod. Retract the rod section by section.

[0060] S6: Turn off the power, remove the curved elastic rod 21, put them into the storage bag, and leave the nest site as soon as possible.

[0061] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
