Description

Technical Field

[0001] This invention belongs to the technical field of resident bird monitoring stations, specifically relating to a portable resident bird monitoring station suitable for urban environments. Background Technology

[0002] With the acceleration of urbanization, urban parks, green spaces and other green areas have become key habitats for maintaining biodiversity. As an indicator group that is extremely sensitive to environmental changes, resident birds directly reflect the integrity and stability of urban ecosystems through their population dynamics, behavioral patterns and health status. Therefore, carrying out refined urban resident bird monitoring has become the core foundation for biodiversity conservation and urban ecological assessment. Traditional monitoring relies on manual transect surveys, which are not only time-consuming and labor-intensive with high professional thresholds, but also difficult to achieve continuous data collection around the clock, and cannot meet the needs of large-scale and high-frequency monitoring. Automatic monitoring technology based on miniaturized and intelligent equipment has become an inevitable trend in the development of this field. To overcome the limitations of traditional monitoring, portable bird monitoring technology has been gradually developed and applied. Among the existing technologies, some solutions focus on long-distance observation of wild bird flocks. For example, a stereo vision system is built using a consumer-grade camera phone to reconstruct the flight trajectory of bird flocks through multi-view imaging. Although it has portability and deployment flexibility, it is mainly aimed at the study of wild group behavior and is not adapted to the characteristics of resident birds in urban environments, such as their solitary nature and small activity range. Moreover, the monitoring dimension is limited to visual imaging and lacks the collaborative capture of multi-sensory data. Another solution integrates video image and audio acquisition modules and combines sound source localization technology to realize automatic recording and location tracing of bird activity. However, its sensor layout and data processing logic focus more on "target discovery" and fail to optimize monitoring accuracy for special environments such as urban background noise interference and frequent human activity. Although passive acoustic monitoring technology has achieved the advantages of low power consumption and long-term monitoring and can record environmental parameters such as temperature and humidity at the same time, single acoustic monitoring is difficult to fully reflect the key information such as the morphological characteristics and resting behavior of resident birds. In high-density building areas, it is easily affected by traffic and industrial noise, which leads to a decrease in recognition accuracy. In terms of equipment protection and functional integration, existing portable monitoring devices still have significant shortcomings. On the one hand, to ensure sensor sensitivity, the devices typically have pre-drilled holes for optical lenses, acoustic acquisition, and heat dissipation. However, when not monitoring, these openings are exposed to the urban environment for extended periods, making them susceptible to blockage by dust and rainwater, or malfunction due to bird droppings or corrosive gases, significantly shortening their lifespan. Existing protection solutions for monitoring equipment primarily focus on repelling birds and diverting droppings, without designing appropriate sealing and protection mechanisms for the opening structures of the monitoring devices. On the other hand, existing technologies have limitations in monitoring and sample collection. The bottleneck of separation is that most bird droppings collection devices are independent field sampling devices that attract birds to defecate by using simulated lawns or foldable birdcages. Although they can collect samples, they cannot be integrated with the monitoring system, resulting in the loss of key information such as the bird species and behavioral background corresponding to the droppings samples. Moreover, the separate deployment increases the operational complexity in the small urban space. In addition, existing monitoring devices either focus on long-distance group observation or use structures such as spikes to drive away lingering birds, making it difficult to achieve close-range observation of resident birds in the city and obtain detailed data such as their feather condition and subtle behaviors, thus limiting the depth of monitoring. In summary, current portable bird monitoring technologies have significant shortcomings in adaptability to urban environments. Their multi-sensor collaborative monitoring capabilities and environmental interference resistance need improvement. The equipment channels lack targeted protective designs, the integration of monitoring and sample collection is low, and close-range observation of resident birds is difficult. These deficiencies prevent existing equipment from efficiently and accurately meeting the refined monitoring needs of urban resident birds. Therefore, there is an urgent need to develop an integrated portable monitoring device that combines multi-dimensional monitoring, equipment protection, close-range observation, and sample collection functions. Summary of the Invention

A threaded rod is rotatably connected between the L-shaped mounting plate and the bottom collection chamber. The output end of the first motor passes through the L-shaped mounting plate and connects to the threaded rod. At least one limiting strip is fixed between the L-shaped mounting plate and the bottom collection chamber. A mounting frame is slidably connected to the outer side of the limiting strip, and the mounting frame is threadedly connected to the threaded rod. The monitoring component is installed within the mounting frame. A movable plate is slidably connected inside the observation port.

[0006] The pressing structure includes multiple connecting strips rotatably connected inside the bottom collection chamber, and each connecting strip is disposed diagonally above each moving plate. A transmission wheel is fixed to the outer side of each connecting strip and the threaded rod. Two transmission wheels are connected by a belt. A first gear is fixed to the outer side of each connecting strip. A first rack is slidably connected to the inner wall of the bottom collection chamber, and the first rack meshes with the first gear. An abutment plate is fixed inside the bottom collection chamber on the moving plate, and the abutment plate is disposed near the top of the moving plate. An abutment block is fixed to the side of the first rack near the abutment plate, and the abutment block is disposed above the abutment plate. When the first rack moves downward, the abutment block presses the abutment plate downward.

[0007] A blocking block is fixed on the outside of the limiting strip and between the mounting bracket and the transmission wheel.

[0008] The support assembly includes an artificial bird's nest mounted on the top of the top connecting compartment. The upper side of the artificial bird's nest is provided with a collecting arc groove, and the collecting arc groove is inclined towards the inner side of the artificial bird's nest. A weight sensor is installed between the artificial bird's nest and the top connecting compartment.

[0016] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0017] like Figures 1-8As shown, a portable resident bird monitoring station suitable for urban environments includes a bottom collection compartment 1, a top connecting compartment 2 threadedly connected to the top of the bottom collection compartment 1, a top plate 3 provided on the upper part of the top connecting compartment 2, and a plurality of accordion folding plates 4 provided between the top connecting compartment 2 and the top plate 3. The plurality of accordion folding plates 4 are all located at the edge positions of the top connecting compartment 2 and the top plate 3. When the top plate 3 moves toward the top connecting compartment 2, the accordion folding plates 4 fold. In its initial state, the accordion folding plate 4 is folded, and the top plate 3 is almost flush with the top connecting compartment 2, making the monitoring station portable. When the monitoring station needs to be used, the top plate 3 and the top connecting compartment 2 can be pulled apart to unfold the accordion folding plate 4. A hook or other device can be installed on the top plate 3 so that the top plate 3 can be hung on a tree branch to monitor resident birds. Multiple monitoring components 14 are installed inside the bottom collection chamber 1. Each monitoring component 14 contains various monitoring devices, such as sound and light monitors and cameras, which can monitor the calls or forms of resident birds. The multiple monitoring components 14 are distributed around the inside of the bottom collection chamber 1, so that the monitoring components 14 can monitor the environment around the bottom collection chamber 1. Multiple observation ports 7 are provided on the inner wall of the bottom collection chamber 1, and each observation port 7 corresponds to each monitoring component 14. A moving mechanism is installed inside the bottom collection chamber 1 to move the monitoring components 14. See attached document Figure 3 and attached Figure 6 The moving mechanism includes multiple L-shaped plates 9, which are fixed inside the bottom collection chamber 1. The L-shaped plates 9 are respectively located at the lower part of the observation port 7. A first motor 10 is installed on the side of the L-shaped plate 9 away from the bottom collection chamber 1. A threaded rod 11 is rotatably connected between the L-shaped plate 9 and the bottom collection chamber 1. The output end of the first motor 10 passes through the L-shaped plate 9 and is connected to the threaded rod 11. At least one limiting strip 12 is fixed between the L-shaped plate 9 and the bottom collection chamber 1. A mounting frame 13 is slidably connected to the outside of the limiting strip 12. The mounting frame 13 is threadedly connected to the threaded rod 11. The monitoring component 14 is installed in the mounting frame 13. When it is necessary to move the monitoring component 14 out of the bottom collection chamber 1, the first motor 10 can be driven so that the output end of the first motor 10 drives the threaded rod 11 to rotate. Combined with the threaded connection between the threaded rod 11 and the mounting frame 13, and through the sliding connection between the mounting frame 13 and the limiting strip 12, the mounting frame 13 can drive the monitoring component 14 to move towards the observation port 7, so that the monitoring component 14 can extend out of the observation port 7 to the outside of the bottom collection chamber 1, thereby enabling the monitoring of resident birds around the bottom collection chamber 1. A blocking pad can be set on the outside of the monitoring component 14 or the mounting frame 13 to block the space outside the observation port 7 except for the monitoring component 14, so as to prevent external impurities from entering the bottom collection chamber 1. A movable plate 8 is slidably connected inside the observation port 7. A mounting groove 22 is provided inside the bottom collection chamber 1 and located at the bottom of the observation port 7, and the movable plate 8 is slidably connected to the mounting groove 22. A spring 23 is installed in the mounting groove 22 and is connected to the movable plate 8. A pressing structure is installed between the bottom collection chamber 1 and the threaded rod 11. The pressing structure is used to press the movable plate 8 downward toward the mounting groove 22. When the monitoring component 14 moves, the pressing structure presses the movable plate 8 downward toward the mounting groove 22, thereby compressing the spring 23 and exposing the observation port 7. This allows the monitoring component 14 to extend to the outside of the bottom collection chamber 1. When the monitoring component 14 moves into the bottom collection chamber 1, the pressing structure removes its obstruction of the movable plate 8. The movable plate 8 moves toward the observation port 7 under the elastic force of the spring 23, thereby blocking the observation port 7 and further ensuring that external impurities are prevented from entering the bottom collection chamber 1 from the observation port 7.

[0018] See attached document Figure 6 The pressing structure includes multiple connecting bars 15 rotatably connected inside the bottom collection chamber 1, and each connecting bar 15 is located diagonally above each moving plate 8. A transmission wheel 16 is fixed to the outside of the connecting bar 15 and the threaded rod 11. The two transmission wheels 16 are driven by a belt 17. A first gear 18 is fixed to the outside of the connecting bar 15. A first rack 19 is slidably connected to the inner wall of the bottom collection chamber 1, and the first rack 19 is meshed with the first gear 18. An abutment plate 21 is fixed inside the bottom collection chamber 1 of the moving plate 8, and the abutment plate 21 is located near the top of the moving plate 8. An abutment block 20 is fixed to the side of the first rack 19 near the abutment plate 21, and the abutment block 20 is located above the abutment plate 21. When the first rack 19 moves down, the abutment block 20 presses the abutment plate 21 down. When the threaded rod 11 rotates, it drives the belt 17 via the transmission wheel 16, which in turn drives the transmission wheel 16 on the connecting bar 15 to rotate. This, in turn, drives the connecting bar 15 and the first gear 18 to rotate. Through the meshing connection between the first gear 18 and the first rack 19, the first rack 19 moves downward, causing the abutment block 20 to move downward, which in turn causes the abutment plate 21 and the moving plate 8 to move downward. When the threaded rod 11 reverses direction, it drives the first rack 19 to move upward, thus relieving the pressure of the abutment block 20 on the abutment plate 21. This causes the moving plate 8 and the abutment plate 21 to move upward due to the elastic force of the spring 23, thereby blocking the observation port 7. Due to the threaded connection between the threaded rod 11 and the mounting bracket 13, the mounting bracket 13 drives the monitoring component 14 to move to... When the observation port 7 is in position, it takes a certain amount of time. The threaded rod 11 directly drives the first gear 18 to rotate, which in turn drives the moving plate 8 to move down. When the monitoring component 14 moves to a position close to the observation port 7, the moving plate 8 has already moved to expose the observation port 7. A blocking block 32 is fixed on the outside of the limiting strip 12 and between the mounting bracket 13 and the transmission wheel 16. By setting the blocking block 32, the blocking block 32 can prevent the mounting bracket 13 from contacting the blocking block 32 first when it moves towards the belt 17, thereby avoiding collision with the belt 17. The belt 17 is replaced by a chain, and the transmission wheel 16 can be replaced by a sprocket, thereby ensuring the transmission performance of the transmission wheel 16 and the belt 17.

[0019] See attached document Figure 6 The top connecting compartment 2 is equipped with a support assembly, which includes an artificial bird's nest 5 mounted on the top of the top connecting compartment 2. The upper side of the artificial bird's nest 5 is provided with a collection arc groove 6, which is inclined towards the inner side of the artificial bird's nest 5. A weight sensor 24 is installed between the artificial bird's nest 5 and the top connecting compartment 2. An adapter groove 36 is provided on the lower side of the top plate 3 and directly above the artificial bird's nest 5. Through the setting of the artificial bird's nest 5 and the collection arc groove 6, resident birds can nest in the collection arc groove 6 to rest when they stop flying. The bottom collecting compartment 1 is also equipped with a controller and a chip. When the weight sensor 24 is pressed, it transmits a signal to the chip. The chip controls the following observation component to start through the controller, so that when the top plate 3 moves down until it is in contact with the top connecting compartment 2, the setting of the adapter groove 36 can prevent the artificial bird's nest 5 and the top plate 3 from blocking each other. See attached document Figures 7-8 An observation assembly is installed on the top plate 3. The observation assembly includes a ring frame 30, which is rotatably connected to the bottom of the top plate 3. Multiple monitoring cameras 35 are installed inside the ring frame 30, and each monitoring camera 35 is tilted towards the direction close to the artificial bird nest 5. When the controller receives a signal, it can control multiple monitoring cameras 35 to start synchronously, so that the monitoring cameras 35 can observe the resident birds nested in the artificial bird nest 5 and observe their shape, feather color and other conditions. A drive structure is installed inside the top plate 3 to drive the ring frame 30 to rotate. The drive structure includes a third motor 40 installed inside the top plate 3. A third gear 39 is fixed vertically upward at the output end of the third motor 40. An annular rack 38 is provided on the inner wall of the ring frame 30 at a position corresponding to the third gear 39, and the annular rack 38 is meshed with the third gear 39. When it is necessary to rotate the ring frame 30, the third motor 40 can be driven, so that the output end of the third motor 40 drives the third gear 39 to rotate, and the rotation is achieved through the third gear 39 and the annular rack. The meshing connection between 38 allows the third gear 39 to drive the ring rack 38 and the ring frame 30 to rotate, thereby driving multiple monitoring cameras 35 to rotate as well. This allows the multiple monitoring cameras 35 to adjust and observe the resident birds from different angles. The top of the top connecting compartment 2 and directly below the ring frame 30 is provided with an adapter ring groove 37. When the top plate 3 moves down and causes the ring frame 30 to move down, the adapter ring groove 37 allows the ring frame 30 to move down until it is inserted into the adapter ring groove 37, avoiding any obstruction between it and the top connecting compartment 2.

[0020] See attached document Figures 3-5 Both the artificial bird nest 5 and the top connecting chamber 2 have a droppings trough 31 at their center. The bottom collection chamber 1 has an installation plate 33 with a sliding groove 34 inside. The sliding groove 34 has a sliding collection box 25 inside. The top of the sliding collection box 25 has a collection groove 26 at the bottom of the droppings trough 31. When the resident bird's nest is on the artificial bird nest 5, the droppings of the resident bird can be collected and guided by the collection arc groove 6, so that some of the droppings roll into the collection groove 26 in the sliding collection box 25. The bottom collection chamber 1 can be unscrewed through the threaded connection between the bottom collection chamber 1 and the top connecting chamber 2 to collect the droppings in the collection groove 26. This allows for the monitoring of information such as the resident bird's food based on the droppings.

[0021] The sliding collection box 25 is slidably connected to the sliding groove 34. Multiple collection grooves 26 are evenly arranged above the sliding collection box 25. A second rack 27 is provided at the bottom of the sliding collection box 25. A second motor 29 is mounted on the bottom of the mounting plate 33. A second gear 28 is fixed to the output end of the second motor 29, and the second gear 28 meshes with the second rack 27. By driving the second motor 29, the output end of the second motor 29 drives the second gear 28 to rotate. Through the meshing connection between the second gear 28 and the second rack 27, the second gear 28 drives... The second rack 27 and the sliding collection box 25 move, causing the sliding collection box 25 to move along the sliding groove 34 on the mounting plate 33, and then move to different adapter grooves 36 to collect the droppings of different resident birds. When the monitoring camera 35 detects that the resident bird has flown away, it can drive the signal to be transmitted to the chip, and the chip can transmit the signal to the controller. The controller controls the second motor 29 to drive and move the sliding collection box 25 until the next collection groove 26 moves to the bottom of the droppings trough 31 to collect the droppings of the next resident bird that lands on the artificial bird nest 5. The bottom collection compartment 1 is equipped with a battery, which can power the electrical components on the bottom collection compartment 1 and the top plate 3. The bottom collection compartment 1 can also be connected to the mains power for power supply.
