Description

Technical Field

[0001] This invention belongs to the field of wildlife conservation and ecological engineering, and specifically relates to an intelligent nest box device for attracting wild mandarin ducks. Background Technology

[0002] As an important indicator species of wetland ecosystems in my country, wild mandarin ducks rely heavily on natural tree cavities for their breeding. However, with the continuous acceleration of urbanization and the ongoing transformation of aquatic environments, the number of natural nest sites suitable for wild mandarin duck breeding is decreasing, which directly threatens the stable development of wild mandarin duck populations.

[0003] To alleviate the shortage of nesting sites, traditional artificial nest boxes have been introduced. However, these boxes have several limitations: they are functionally limited, providing only basic habitat space and failing to meet the diverse needs of mandarin ducks during breeding; they have poor environmental adaptability, struggling to cope with the complex and ever-changing climate and ecological conditions in the wild; in terms of materials, they mostly use artificial boards, which not only have high formaldehyde content, potentially harming the health of mandarin ducks, but also have relatively high manufacturing costs; more importantly, traditional artificial nest boxes generally lack effective monitoring mechanisms and data support capabilities, failing to provide accurate and timely information for ecological conservation research on wild mandarin ducks, and thus failing to meet the practical needs of modern ecological conservation work and scientific monitoring; furthermore, the existing nest boxes have unreasonable fixing structures, cumbersome installation processes, and difficulty in quickly and stably fixing them to tree trunks of different diameters and shapes. Moreover, they often use rigid fixing methods, which can cause continuous compression damage to the tree trunk as the tree grows, affecting normal tree growth and potentially causing the nest box to loosen and fall off, further reducing the practical application effect of artificial nest boxes. Summary of the Invention

[0004] To overcome the problems of traditional artificial nest boxes, such as limited functionality, poor environmental adaptability, health risks and high cost of materials, lack of effective monitoring mechanisms and data support capabilities, unreasonable fixed structure design leading to cumbersome installation and easy damage to trees and nest box loosening and falling off, a smart nest box device for attracting wild mandarin ducks is proposed.

[0014] Furthermore, the simulation mechanism includes a support rod fixed to the upper end of the fixed column, a bearing block fixed to the upper part of the side wall of the support rod, and multiple simulated branches fixed to both sides of the bearing block.

[0019] The beneficial effects of this invention are:

[0020] 1. By incorporating components such as temperature and humidity sensors, RFID devices, and infrared sensors, multi-dimensional monitoring of the internal environment of the nest box and the activities of mandarin ducks is achieved. The temperature and humidity sensors can detect changes in temperature and humidity inside the lower tray in real time, providing data reference for a suitable environment for mandarin duck breeding. The RFID device can record the entry and exit information of mandarin ducks, helping to study their activity patterns. The infrared sensor, in conjunction with the entry mechanism, can accurately detect the entry and exit status of mandarin ducks. At the same time, the through slots and ventilation slots on the fixing plate ensure air circulation inside the nest box, meeting the environmental needs of mandarin ducks during the breeding process, breaking the limitation of traditional nest boxes that can only provide habitat space.

[0021] 2. The solar panels in the intelligent control components provide energy for the entire device. Combined with the inverter and battery, they can provide stable power supply under different lighting conditions and adapt to the complex energy environment in the wild. The simulation mechanism simulates the vegetation morphology in the natural environment through the support blocks and simulated branches on the support rods, reducing the mandarin ducks' aversion to artificial nest boxes and improving their adaptability. In addition, the structural design of the lower support tube and straight tube can effectively resist the impact of wind, rain and other climates, enhancing the adaptability of the nest box in complex climate and ecological conditions in the wild.

[0022] 3. This invention does not use traditional artificial boards, but instead uses natural wood or other environmentally friendly materials to make each component, thus avoiding the potential harm of formaldehyde and other harmful substances to the health of mandarin ducks from the source. At the same time, the application of solar panels reduces the dependence on external power, reduces long-term use costs, and the detachable design of each component facilitates maintenance and replacement, further reducing the overall cost.

[0023] 4. The camera in the intelligent control component can capture real-time images of the inside and surrounding area of ​​the nest box. The microcontroller and wireless transceiver in the control box can transmit the data collected by the camera, temperature and humidity sensor, RFID device, infrared sensor, etc. to the background in a timely manner, providing accurate and timely information for the ecological protection research of wild mandarin ducks, and meeting the actual needs of modern ecological protection work and scientific research monitoring.

[0024] 5. The first and second clamping components use the first bolt and the second nut to clamp and fix tree trunks of different diameters and shapes. The installation process is simple and convenient. At the same time, this clamping method is not rigid, which can adapt to the growth of trees and avoid continuous compression damage to the tree trunk. The cooperation between the limiting post and the second limiting cylinder in the auxiliary support mechanism enhances the stability of the nest box fixation, prevents the nest box from loosening and falling off, and improves the practical application effect of artificial nest boxes.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Mandarin ducks, a Class II protected animal in China, are highly regarded for their beautiful plumage and unique lifestyle. In their natural environment, mandarin ducks rely on suitable nests for breeding, but traditional nesting sites such as natural tree cavities are becoming increasingly scarce due to urbanization and human activities. To effectively protect mandarin duck populations and promote their breeding and habitat, intelligent nest box devices have emerged as an innovative conservation method.

[0038] The design of the smart nest box is based on several factors, primarily the ecological habits of mandarin ducks. Mandarin ducks typically choose natural tree cavities in tall trees near water as their nests. These cavities are generally 3-10 meters above the ground, with an opening diameter of about 8-10 centimeters, providing ample space for the female to lay eggs, incubate, and raise her young. Therefore, the smart nest box design references these dimensions, using wood to simulate the appearance and texture of a natural tree cavity, providing a similar internal space. An opening of about 8-10 centimeters in diameter is located at the top front of the nest box for easy entry and exit. Furthermore, mandarin ducks prefer quiet, secluded environments with good water quality. Therefore, nest boxes are often located near lakes, wetlands, and other bodies of water in parks. Tall trees with a diameter at breast height of 40-60 centimeters are chosen as the hanging carrier, 5-6 meters above the ground. This ensures the stability of the nest box, provides a sense of security for the ducks, and aligns with their preference for the height of natural tree cavities. Besides ecological habits, functional requirements are also a crucial design consideration. To monitor the activities of mandarin ducks in their nest boxes in real time, existing smart nest boxes are equipped with high-definition cameras. These cameras transmit images from inside the nest box to a data receiving terminal via wireless transmission technology. Researchers and conservationists can then view the images anytime using a mobile app or computer software, recording the mandarin ducks' egg-laying, incubation, and chick-rearing behaviors, thus providing data support for scientific research.

[0039] In some regions with variable climates, the temperature inside the nest box is crucial for the incubation of mandarin duck eggs and the survival of chicks. Some smart nest boxes are equipped with temperature sensors, controllers, and heating devices. When the temperature sensor detects that the temperature inside the nest box is below the suitable range (generally 30-35 degrees Celsius), the controller activates the heating device to maintain a stable temperature inside the nest box and improve the hatching success rate.

[0040] In practical applications, several regions have reported relevant cases. Since 2016, Zhaolin Park in Harbin has installed artificial nest boxes, some of which are intelligent nest boxes. Statistics show that the breeding success rate of Mandarin ducks has improved after the installation of intelligent nest boxes. Through video monitoring, researchers observed that the number of eggs per nest for Mandarin ducks is generally 10-12. The behaviors of female Mandarin ducks during incubation, such as turning their eggs, were also recorded in detail. Furthermore, phenomena such as multiple Mandarin ducks "competing" for the same nest box and "nest parasitism" (other Mandarin ducks laying their eggs in already occupied nest boxes) have been studied and understood more deeply. On the campus of Harbin Medical University, in 2023, the project team installed seven artificial nest boxes for Mandarin ducks, five of which were used by Mandarin ducks for egg laying and incubation, resulting in a nest box utilization rate of 71.4%. Through the installation of intelligent video monitoring equipment by Bai Niao (a bird monitoring platform) inside and outside the nest boxes, the behavior of Mandarin ducks during their breeding cycle was recorded, obtaining a large amount of first-hand Mandarin duck breeding data, providing strong data support for campus ecological protection and Mandarin duck conservation efforts. With the support of the Hangzhou West Lake Water Management Office and other units, the first batch of artificial nest boxes for mandarin ducks has been hung in Liulang Wenying Park in Hangzhou West Lake. These nest boxes are made of natural wood (Mongolian oak, maple, etc.), with smooth and rounded entrances and exits, blending into the environment. Although no intelligent functions are explicitly mentioned, some nest boxes are equipped with simple monitoring devices and are expected to be upgraded to intelligent nest boxes in the future to further monitor the use of nest boxes by mandarin ducks and the breeding effect.

[0041] Intelligent nest boxes have played a crucial role in the conservation of wild mandarin ducks. By simulating the natural nesting environment and providing monitoring and regulation functions, they effectively meet the breeding and habitat needs of mandarin ducks, improve breeding success rates, and provide abundant data for scientific research. In the future, intelligent nest boxes can be further optimized, such as by adding monitoring of more environmental parameters (e.g., air quality, light intensity, and ambient noise levels), improving data transmission stability and security, and reducing costs to expand their application scope. Simultaneously, by combining artificial intelligence technology, they can achieve automatic analysis and early warning of mandarin duck behavior, providing more precise and efficient technical support for wild mandarin duck conservation, allowing these beautiful wild birds to thrive and multiply better in both urban and natural environments under human protection.

[0047] In use, the mounting cylinder 3 is installed on the upper end of the lower support cylinder 1, the straight cylinder 4 is installed on the upper end of the mounting cylinder 3, and the intelligent control component 5 is threaded onto the upper end of the straight cylinder 4. Then, the second bolt 11 passes through the second protrusion 10 and the welding ring 2 and extends to the lower part of the welding ring 2.

A second limiting cylinder 15 is fixed to the lower end of the horizontal block, and the inner wall of the second limiting cylinder 15 and the upper part of the side wall of the limiting post 14 are attached to each other.

The upper end of the stop block 21 is in contact with the lower end of the rotating disk 19. When the threaded posts 20 rotate and the stop block 21 releases its obstruction of the rotating disk 19, the rotating disk 19 can rotate along the inside of the circular groove. A ventilation groove 22 is extending through the side wall of the lower support cylinder 1.

[0050] In this embodiment, specifically: the entry mechanism includes a through circular hole opened in the side wall of the straight cylinder 4, an inlet 16 is fixedly connected to the side wall of the straight cylinder 4, the inner wall of the inlet 16 is flush with the inner wall of the circular hole of the straight cylinder 4, an infrared sensor 17 is fixedly connected to the end of the inlet 16 away from the straight cylinder 4, and a standing block 18 is fixedly connected to the side wall of the straight cylinder 4, the standing block 18 is located below the inlet 16.

[0051] In this embodiment, specifically: a third fixing ring 23 is fixedly connected to the upper part of the inner wall of the lower support cylinder 1, and multiple temperature and humidity sensors 24 are fixedly connected to the lower end of the third fixing ring 23. An RFID device 25 is fixedly connected to the inner wall of the lower support cylinder 1. An inner ring 31 is fixedly connected to the inner wall of the mounting cylinder 3. A fixing disk 32 is fixedly connected to the inner wall of the inner ring 31. Multiple through slots are opened through the upper end of the fixing disk 32. A uniformly distributed first threaded rod 33 is fixedly connected to the upper end of the inner ring 31. A first nut 34 is threadedly installed on the side wall of the first threaded rod 33. A first fixing ring 41 is fixedly connected to the lower part of the inner wall of the straight cylinder 4. A uniformly distributed through hole is opened through the upper end of the first fixing ring 41. The inner wall of the through hole and the side wall of the first threaded rod 33 are in contact. The lower end of the first nut 34 abuts against the upper end of the first fixing ring 41.

[0052] In this embodiment, specifically: the simulation mechanism includes a support rod 71 fixed to the upper end of the fixed column 7, a bearing block 72 fixed to the upper part of the side wall of the support rod 71, and multiple simulated branches 73 fixed to both sides of the bearing block 72.

[0053] In this embodiment, specifically: the intelligent control component 5 includes a first limiting cylinder 51 threadedly installed on the inner wall of the upper end of the straight cylinder 4, a fixing box 52 fixed to the upper end of the first limiting cylinder 51, a camera 53 fixed to the top surface of the inner wall of the fixing box 52, and a control box 54. The control box 54 is equipped with a microcontroller, an inverter, a wireless transceiver, and a battery. An inclined block 55 is fixed to the upper end of the fixing box 52, and a solar panel 56 is fixed to the upper end of the inclined block 55.

[0054] Example 1: In this example, specifically: the first clamping component 6 includes a first arc-shaped block 61 fixed to both sides of the side wall of the horizontal block, and a vertical plate 62 fixed to one end of each of the two first arc-shaped blocks 61 that is close to each other. There is a gap between the two vertical plates 62, and at least two first bolts 63 are threaded through on the two vertical plates 62. Two second nuts 64 are threaded on the side wall of the first bolts 63.

[0055] By setting up a first arc-shaped block 61, a vertical plate 62, a first bolt 63, and a second nut 64, the spacing of the vertical plate 62 can be adjusted by adjusting the position of the second nut 64 on the first bolt 63, thereby adapting to clamping requirements of different sizes. The structure is simple and the connection is stable.

[0056] Example 2: In this example, specifically: the first clamping assembly 6 includes a second arc-shaped block 65 fixed to both ends of the horizontal block, or a second arc-shaped block 65 rotatably connected to the horizontal block via a rotating member, an arc-shaped frame 66 fixed to one end of the two second arc-shaped blocks 65 that is far apart from each other, a second threaded rod 67 slidably disposed on the inner wall of the arc-shaped frame 66, a sleeve block 68 fixed to the side wall of the two second threaded rods 67, and a third nut 69 threadedly installed on the side wall of the second threaded rod 67. A first protrusion 610 is fixed to one end of the sleeve block 68 near the welding ring 2. A reflector 611 is fixed to the upper part of the side wall of the second threaded rod 67, and the lower end of the reflector 611 is fixed to the upper end of the sleeve block 68.

[0057] By setting up a second arc-shaped block 65, an arc-shaped frame 66, a second threaded rod 67, a sleeve block 68, a third nut 69, a first protrusion 610, and a reflector 611, the second threaded rod 67 can slide within the arc-shaped frame 66 and be fixed by the third nut 69. The positions of the sleeve block 68 and the first protrusion 610 can be flexibly adjusted to adapt to different clamping scenarios. The reflector 611 can provide auxiliary lighting or reflective functions to improve operational visibility. At the same time, the second arc-shaped block 65 can be rotated by a rotating component, increasing the flexibility of the clamping angle.

[0058] Example 3: This example is based on Example 2, specifically: the rotating component is a rotating block 612, which is fixed to the horizontal block, and the second arc-shaped block 65 is rotatably mounted on the rotating block 612.

[0059] By setting the rotating block 612, the second arc-shaped block 65 can rotate around the rotating block 612, realizing the flexible adjustment of the angle of the second arc-shaped block 65. This makes it easy to change the clamping direction according to actual needs, improving the adaptability of the component. Moreover, this design is suitable for situations with larger trunk diameters. Compared with the second arc-shaped block 65, which is directly fixed to both ends of the horizontal block without the rotating block 612, it increases the deformable range of the second arc-shaped block 65, making it easier to clamp trunks with larger diameters.

[0060] Working principle: When the device is working, the inner ring 31 of the mounting cylinder 3 is first placed on the upper end of the third fixing ring 23 on the upper part of the inner wall of the lower support cylinder 1, so that the inner wall of the mounting cylinder 3 is in contact with the upper part of the side wall of the lower support cylinder 1. Then, the first fixing ring 41 on the lower part of the inner wall of the straight cylinder 4 is sleeved on the first threaded rod 33 of the mounting cylinder 3, so that the first threaded rod 33 passes through the through hole of the first fixing ring 41. Then, the first nut 34 is threaded on the side wall of the first threaded rod 33, so that the lower end of the first nut 34 abuts against the upper end of the first fixing ring 41, thereby fixing the straight cylinder 4 and the mounting cylinder 3.

[0061] Then, the first limiting cylinder 51 of the intelligent control component 5 is threaded onto the inner wall of the upper end of the straight cylinder 4. The camera 53 and control box 54 in the fixed box 52 can remotely view the breeding status and capture individual images. The solar panel 56 at the upper end of the inclined block 55 provides power to the battery in the control box 54.

[0062] Next, the second bolt 11 is passed through the second protrusion 10 on the side wall of the mounting cylinder 3 and the welding ring 2 on the side wall of the lower support cylinder 1 and extends to below the welding ring 2. The fourth nut 12 is threaded on the lower end side wall of the second bolt 11 so that the lower end of the second protrusion 10 abuts against the upper end of the second fixing ring 8 at the upper end of the welding ring 2, thereby fixing the mounting cylinder 3 and the welding ring 2.

[0063] The device is installed on the tree trunk using the first clamping component 6 and the second clamping component 9. If it is the first clamping component 6 of Embodiment 1, the two first arc-shaped blocks 61 are attached to the tree trunk. The position of the first bolt 63 passing through the two upright plates 62 is adjusted, and then the second nut 64 is rotated to make it abut against the upright plate 62, so as to adjust the spacing of the upright plates 62 to clamp the tree trunk.

[0064] If it is the first clamping component 6 of embodiment 2, the second arc-shaped block 65 is attached to the tree trunk, the second threaded rod 67 in the sliding arc frame 66 adjusts the position of the sleeve block 68 and the first protrusion 610, and the third nut 69 is rotated to abut against the arc frame 66 to fix it. The angle of the second arc-shaped block 65 can be adjusted by rotating the rotating block 612 around the horizontal block, so that the tree trunk is clamped between the two second arc-shaped blocks 65 and the first protrusion 610.

[0065] The limiting post 14 at the upper end of the connecting block 13 of the second clamping assembly 9 can be inserted into the second limiting cylinder 15 at the lower end of the horizontal block, so that the upper part of the side wall of the limiting post 14 fits against the inner wall of the second limiting cylinder 15, providing auxiliary support for the lower end of the welding ring 2.

[0066] If it is as in Example 3, it can handle tree trunks with a larger diameter;

[0067] Wild mandarin ducks can perch on the standing block 18 on the side wall of the straight cylinder 4 and enter the interior of the lower support cylinder 1 through the inlet 16. The infrared sensor 17 at the inlet 16 can detect their entry and exit. The RFID device 25 on the inner wall of the lower support cylinder 1 and the temperature and humidity sensor 24 at the lower end of the third fixing ring 23 can monitor the internal status.

[0068] When unloading, rotate the threaded post 20 at the lower end of the lower support cylinder 1 to move the lower end of the stop block 21 downward to release the obstruction of the rotating disk 19. The rotating disk 19 can unload by rotating along the inner wall of the circular groove at the lower end of the lower support cylinder 1. The ventilation groove 22 on the side wall of the lower support cylinder 1 can ensure internal ventilation.

[0069] The simulated branches 73 on both sides of the support rod 71 at the top of the fixed column 7 can enhance the attraction to wild mandarin ducks. The whole system achieves functions such as attracting wild mandarin ducks and monitoring their reproduction through the synergistic effect of each component.
