[0002] Otter fecal odor retention detection devices are used to monitor and analyze the odor emitted by otter feces to facilitate research on otter behavior and habitats. These devices, often combined with sensor technology, can detect changes in the concentration of specific compounds, thereby determining otter activity and population numbers. By collecting long-term data, researchers can gain a deeper understanding of the ecological needs of otters and their role in the ecosystem, providing a scientific basis for the conservation and management of otter populations.

A motor 3 is installed on the top of the base 1, the base 1 supports and fixes the motor 3. The driving end of the motor 3 is fixedly connected to the rotating shaft 4, and the motor 3 is started, and the rotation of the driving end of the motor 3 drives the rotating shaft 4 to rotate. The top of the rotating shaft 4 is fixedly connected to a gear 5, and the rotation of the rotating shaft 4 drives the gear 5 to rotate. The inner wall of the frame cover 2 is slidably connected to a mesh plate 7, and the frame cover 2 supports and fixes the mesh plate 7. The outside of the gear 5 is meshedly connected to the outside of the tooth plate 6, and the rotation of the gear 5 drives the tooth plate 6 to change its position left and right.

[0032] The mesh plate 7 is fixedly connected to the outside with a tooth plate 6, and the movement of the tooth plate 6 drives the mesh plate 7 to change its position. A small hole is opened on the top of the frame cover 2, and a small hole is opened on the inside of the mesh plate 7. The bottom of the small hole is coupled to the top of the small hole, so that the position change of the mesh plate 7 drives the change of the position of the small hole and the small hole. When the position of the small hole and the small hole coincide, it appears that the air inside and outside the device is connected. After a period of time, the internal odor concentration no longer changes, allowing the odor detector 8 to detect external odors without being exposed to the outside world. The odor detector 8 is installed on the top of the base 1. The base 1 has the function of fixing the position of the odor detector 8. The model of the odor detector 8 is XP-329IIIR.

[0033] Reference Figures 2 to 3 The top of the base 1 is fixedly connected to a cleaning component for controlling the removal of internal retained odors. The cleaning component includes a cylinder 9. The top of the cylinder 9 is fixedly connected to a connecting column 10. When the cylinder 9 is started, the movement of the driving end of the cylinder 9 drives the connecting column 10 to move its position. The top of the connecting column 10 is movably connected to a lifting frame 11. The rise or fall of the connecting column 10 drives the lifting frame 11 to rise or fall. The inner wall of the frame cover 2 is rotatably connected to a rotating shaft 12. The frame cover 2 supports and fixes the position of the rotating shaft 12. The outside of the moving column 15 is movably connected to the inner wall of the lifting frame 11. The rise and fall of the lifting frame 11 drives the moving column 15 to change its position.

[0034] The other end of the disc 13 is rotatably connected to a movable column 15, and the position change of the movable column 15 drives the disc 13 to rotate. The other end of the rotating shaft 12 is rotatably connected to the disc 13, and the rotation of the disc 13 drives the rotating shaft 12 to rotate. A ventilator 14 is installed on the outside of the disc 13. The rotation of the disc 13 drives the ventilator 14 to rotate, allowing the ventilator 14 to absorb the air inside the device and replace it with cleaner air, so that each odor detection inside the device will not be affected by the previous detection. The outside of the ventilator 14 is detachably connected to the air pipe 17, and the ventilator 14 has the function of fixing the position of the air pipe 17. The outside of the air pipe 17 contacts the inner wall of the disc 13. The rotation of the disc 13 drives the air pipe 17 to rotate, so that the air pipe 17 will not be entangled with other structures due to rotation.

[0035] The top of the base 1 is fixedly connected to a connection port 16, and the base 1 supports and fixes the connection port 16. The outside of the air pipe 17 is in contact with the inner wall of the connection port 16, and the connection port 16 fixes the air pipe 17 and reduces friction. The inner wall of the base 1 is slidably connected to a drawer 18, and the base 1 supports and fixes the drawer 18. The other end of the air pipe 17 is detachably connected to the top of the drawer 18, and the air pipe 17 is used to connect the inside and outside air and transmit it to the inside of the drawer 18. The inside of the drawer 18 is a cavity, and the inner wall of the cavity is detachably connected to an adsorption plate 19, which has an adsorption effect on odorous gases, so that the odorous gases will not cause harm to the human body during subsequent treatment.

[0036] Working principle: Start the motor 3, the rotation of the driving end of the motor 3 drives the rotating shaft 4 to rotate, the rotation of the rotating shaft 4 drives the gear 5 to rotate, the rotation of the gear 5 can drive the tooth plate 6 to move left and right, the left and right movement of the tooth plate 6 drives the mesh plate 7 to move its position, so that the position change of the mesh plate 7 drives the change of the position of the small holes and the small holes. When the positions of the small holes and the small holes coincide, it appears that the air inside and outside the device are connected. After a period of time, the internal odor concentration no longer changes, so that the odor detector 8 can detect external odors without being exposed to the outside world. Therefore, at a specific detection time, the odor concentration inside the device can be kept stable, and the stability of the gas concentration inside the otter excrement odor retention detection device is controlled to ensure that the sensor is in the best working state, improve the detection accuracy and sensitivity, and reduce the interference of external environmental changes on the measurement results.

[0037] Start the cylinder 9. The position change of the driving end of the cylinder 9 drives the connecting column 10 to rise or fall. The lifting and lowering of the connecting column 10 drives the lifting frame 11 to rise and fall. The position change of the lifting frame 11 drives the moving column 15 to move in contact with the inner wall of the lifting frame 11. The position change of the moving column 15 drives the disc 13 to rotate. The rotation of the disc 13 drives the ventilator 14 to rotate slowly inside the device, making the ventilator 14 more accurate in absorbing and replacing air. Regularly cleaning the inner wall of the otter excrement odor retention detection device can effectively eliminate the influence of the last detection residue, ensure the accuracy and reliability of each detection, thereby improving the sensitivity of the odor detection and ensuring that the equipment is always in the best condition for monitoring.
