[0002] At present, the purpose of bird-repelling work at airports is to ensure that flights are not affected by birds during takeoff and landing, and to reduce the probability of "bird strikes". With the continuous development of related technologies, the methods of bird-repelling at airports are also increasing, such as the common sound wave bird-repelling and bird-repellent bird-repelling methods. Among them, bird-repellent is generally made of pure natural raw materials (or equivalent natural raw materials) and processed into a biological agent. After being deployed and used, it can slowly and persistently release a special fragrance that affects the nervous system and respiratory system of birds. Birds will fly away after smelling it and will not come back during their memory period. It has a long service life and a strong ability to adapt to the environment.

[0003] However, during the actual operation, the applicant found that the bird repellent bags currently used to store bird repellents are mostly hung and installed in a single storage structure, which is prone to the risk of theft and being wet by rain.

[0036] Working principle:

[0037] Example 1

[0038] A proper amount of bird repellent is added to the interior of the filter-type medicine bag 1 through the feeding tube 9. The smell of the bird repellent subsequently passes through the filter-type medicine bag 1, the protective sleeve 2, and the outer protective sleeve 6 and drifts into the use environment, thereby affecting the nervous system and respiratory system of birds, causing them to fly away immediately after smelling it and not return during their memory period.

[0039] As for the anti-lost installation of the entire device, a pit is dug at the designated position, and then the bottom of the hollow support cone rod 8 and the second positioning sleeve 11, the first buffer spring 12, the first positioning sleeve 10 and the pressure detection component 13 are buried in the designated position pit, and the hollow support cone rod 8 is always maintained in a vertical state to the ground, thereby ensuring the stable installation of the entire device;

[0040] Later, when a criminal wants to steal the device, during the process of vigorously shaking the hollow supporting cone rod 8, the movable rod 132 inside the pressure detection component 13 will be pressurized synchronously and the pressure will be transmitted to the pressure sensor 133. The pressure sensor 133 then generates a pressure signal and transmits it to the battery module 5. After the pressure data exceeds the preset standard value, the alarm inside the battery module 5 will sound, prompting airport personnel to catch the thief.

[0041] Example 2

[0042] During the process of the bird repellent odor spreading inside the filter-type medicine bag 1, if the natural wind in the use environment is strong, the outer baffle 32 inside the passive air supply component 3 drives the fan blades 33 to rotate synchronously through the transmission shaft 31, and then the fan blades 33 generate accelerated airflow inside the filter-type medicine bag 1, further accelerating the spread of the bird repellent odor inside the filter-type medicine bag 1;

[0043] If the natural wind in the use environment is weak and the spread speed of the bird repellent odor inside the filter-type medicine bag 1 needs to be accelerated, the axial flow fan 4 is turned on by the battery module 5, and the axial flow fan 4 operates inside the protective sleeve 2 to accelerate the air inside the protective sleeve 2, thereby actively improving the spread speed of the bird repellent odor inside the filter-type medicine bag 1.

[0044] Example 3

[0045] When it rains in the operating environment, the outer protective sleeve 6 can be rotated, and the bearing between the outer protective sleeve 6 and the protective sleeve 2 provides support, and the annular magnet 14 provides a magnetic limiting condition, thereby aligning and closing the air outlet slot inside the outer protective sleeve 6 and the baffle assembly 7. The subsequent expansion of the bird repellent odor can be dispersed through the filter-type medicine bag 1, the protective sleeve 2, and the set gap between the outer protective sleeve 6 and the protective sleeve 2, meeting the use requirements while providing waterproof protection for its main operating structure.
