Description

Technical Field

[0001] This utility model relates to the field of drones, and to a Trichogramma bee dispenser, and more particularly to a Trichogramma bee ball drone delivery and mounting device. Background Technology

[0002] Trichogramma wasps are natural enemies of pests in corn, rice, and forestry, and their drone delivery technology is widely used in modern agricultural pest control. Currently, drone delivery of Trichogramma wasps mainly uses a self-propelled spherical wasp ball, which is launched to the target area by a specialized launcher. These launchers typically rely on a motor-driven dial or crank-slider mechanism to launch the wasp ball at a preset frequency, requiring dynamic matching with the drone's flight speed and altitude.

[0003] However, launching bee balls via a launcher may have the following drawbacks: First, the launching process is affected by fluctuations in flight speed, lateral wind speed, and terrain undulations, making it difficult to synchronize the initial launch velocity with the drone's flight speed in real time, resulting in uneven distribution of bee balls and scattered blank areas in the field; Second, individual bee balls have strong rolling properties in the vegetation canopy, especially in complex terrains such as hillsides and dense forests, making them prone to detaching from the target area and reducing the effective parasitism rate of Trichogramma wasps; Third, the precision transmission components of the launcher (such as gear sets and launch arms) are subjected to impact loads for a long time, and are prone to jamming and deformation due to dust intrusion or mechanical fatigue, requiring frequent maintenance and replacement.

[0004] Furthermore, to adapt to different operational scenarios, the launcher requires repeated adjustments to its launch parameters, making operation complex and demanding high levels of pilot skill. Additionally, during launch, the bee pellets may come into contact with the ground or hard structures, reducing the survival rate of the Trichogramma wasps. These limitations significantly increase time and economic costs in large-scale operations, hindering the efficient dissemination of biological control technologies. Utility Model Content

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0054] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0055] Example 1

[0056] As attached Figures 1 to 9 The illustrated trichroa fetidbit drone deployment and mounting device includes: a drone mounting platform 1, and further includes:

[0057] The bee ball unit group 2 is composed of at least two biodegradable hollow bee balls 201 connected in sequence, and the surface of the bee ball 201 is provided with a channel structure 202 for Trichogramma bees to escape;

[0058] The flexible connector 3 is fixedly connected at both ends to the adjacent honeycomb spheres 201;

[0059] The buffer landing mechanism 4 includes an deployable umbrella-shaped structure 401 and a trigger pull rope 402 connected to the end of the bee ball unit group 2;

[0060] in,

[0061] The drone mounting platform 1 is equipped with a storage section with a locking function;

[0062] The bee ball unit group 2 is stored in the storage part in a coiled form;

[0063] The first end of the trigger pull rope 402 is fixed to the end bee ball 201, and the second end is connected to the umbrella-shaped structure 401. The end refers to the last bee ball 201 that detaches from the UAV mounting platform 1 when the same group of bee ball units 2 unfolds and falls.

[0064] When the locking function is released, the bee ball unit group 2 unfolds and falls under the action of gravity, and the umbrella-shaped structure 401 is pulled open by the trigger pull rope 402.

[0065] Among them: the bottom of the UAV mounting platform 1 is equipped with a flow guide, and the inner wall of the flow guide is arranged with longitudinal flow guide ribs. The longitudinal flow guide ribs are arranged in a gradually changing pattern with sparser front and denser back. The front section of the ribs is processed with a streamlined bevel to guide the airflow diversion, and the rear section is opened with a vortex suppression channel to weaken turbulence. The upper end of the flow guide is connected to the UAV mounting platform 1 through a rotary bearing. The bottom of the flow guide is hinged with an elastic reset protective baffle. The inner surface of the baffle is fitted with the ends of the longitudinal flow guide ribs to form a continuous flow channel. When the honeycomb unit group 2 falls off the circumferential limiting component 502, it hits the baffle and instantly unfolds to form a funnel-shaped diffusion channel to prevent the end collision.

[0066] The bee ball unit group 2 is composed of multiple biodegradable bee balls 201 connected in sequence. The surface of the bee ball 201 has a channel structure 202 for Trichogramma bees to escape. The edge of the channel structure 202 is equipped with a flow guide grid. The two ends of the bee ball 201 are provided with connecting bases 203, and the bases are embedded with rotatable locking sleeves 204. The surface is equipped with an openable and closable air permeable adjustment plate 205. The air permeable adjustment plate 205 is connected to the inner wall through a micro hinge shaft. The end of the hinge shaft is sleeved with a shape memory alloy sheet. The humidity response push rod is set inside and contacts the shape memory alloy sheet. When the ambient humidity exceeds the standard, the push rod extends and pushes the shape memory alloy sheet to deform, driving the air permeable adjustment plate 205 to open and form an airflow guiding angle with the flow guide grid. When falling, it guides the external airflow to rotate into the interior of the ball along the tangential direction of the channel structure 202.

[0067] The flexible connector 3 has two fixed connectors 307 at both ends. The side wall of the connector 307 has a radial groove 308, and the end is provided with a guide cone surface and a pressure sensing ball. The inner wall of the locking sleeve 204 is provided with a spiral protrusion that connects to the locking cavity. When the connector 307 is inserted, the guide cone surface squeezes the spiral protrusion to drive the locking sleeve 204 to rotate, and the pressure sensing ball slides into the cavity to complete the radial locking. The connecting base 203 has a separation spring inside that presses against the outer wall of the locking sleeve 204 and the end face of the connector 307. When falling, gravity triggers the separation spring to release the pre-pressure and push the locking sleeve 204 to rotate slightly to release the lock.

[0068] The flexible connector 3 is composed of three or more biodegradable fiber bundles 301 spirally interwoven to form a tubular body 302. The internal links 303 of the tube are connected by ball joints 304 to form a support frame 305. The ball joints 304 are equipped with radial limiting wing plates with low friction coatings that fit against the inner wall of the tubular body 302. The outer surface of the support frame 305 and the inner wall of the biodegradable fiber bundles 301 are filled with a viscoelastic buffer medium 306. The medium is embedded with shape memory mesh to fix the links 303.

[0069] When the winding device 5 is winding, the support frame 305 is subjected to radial pressure. The ball joint 304 drives the limiting wing plate to slide spirally, forcing the shape memory wire mesh to twist and deform to store energy. The viscoelastic buffer medium 306 generates a shear thickening effect to enhance the compressive strength. When released and falling, the wire mesh returns to its original shape, pushing the chain link 303 to extend axially. Simultaneously, the limiting wing plate is pulled open to form a rigid support, and the buffer medium turns into a viscous flow state to reduce sliding resistance. An axial sliding pair is formed between the inner wall of the tubular main body 302 and the viscoelastic buffer medium 306.

[0070] The surface of the rotating shaft component 501 of the winding device 5 is wound with the honeycomb ball unit group 2, and the flexible connector 3 is wound synchronously with the honeycomb ball 201; the circumferential limiting component 502 includes a variable diameter guide groove module 504, which is composed of two sets of coaxial radially telescopic arc-shaped guide rails 505. The inner surface of the guide rail is provided with staggered limiting protrusions 506, and the root of the protrusions is embedded with an elastic filler block to automatically compensate for the gap; the spacing adjuster 507 includes a worm gear disk 508 and a worm adjustment mechanism 509. The worm input end is connected to a servo motor and the coaxiality is compensated by a floating coupling. The edge of the worm gear disk 508 is provided with an annular ratchet groove; the movable end of the arc-shaped guide rail 505 is provided with a pressure adaptive pawl. The pawl is preloaded by a disc spring to fit the ratchet groove. When the worm drives the worm gear disk 508 to rotate, the pawl engages step by step to pull the arc-shaped guide rail 505 to extend and retract at equal intervals; a stroke buffer is provided at the end of the guide rail extension and retraction trajectory to absorb inertial impact.

[0071] A centrifugal anti-loosening mechanism 510 is added to the end of the variable diameter guide groove module 504. The mechanism includes a counterweight swing arm 511 and a reset spring 512. A linkage slider is set at the root of the counterweight swing arm 511 and is fitted into an annular slide coaxial with the worm gear disk 508. When the UAV turns, the centrifugal force pushes the counterweight swing arm 511 to swing outward. The linkage slider squeezes the bearing seat at the end of the worm gear adjustment mechanism 509 through the wedge-shaped push block, forcing the worm to fine-tune the angle of the worm gear disk 508 and drive the arc-shaped guide rail 505 to retract radially, reducing the gap of the limiting protrusion 506 to enhance the locking depth of the swing end of the counterweight swing arm 511. When the centrifugal force disappears, the reset spring 512 pulls the counterweight swing arm 511 back to its original position. The end locking mechanism 503 locks the end of the winding device 5 by rotating the locking tongue. A sloping groove is opened on the bottom surface of the locking tongue.

[0072] The frame support component 601 of the release control module 6 is rigidly connected to the UAV mounting platform 1. The component integrates an unlocking unit 602 and an environmental sensing unit. The unlocking unit 602 includes an electromagnetic drive component 604 and a linkage push rod 605. The middle of the push rod is provided with a double guide sleeve to form an axial sliding pair, and a wedge-shaped top block is machined at the end. One end of the linkage push rod 605 is hinged to the electromagnetic drive component 604, and the other end passes through the separation component 603 and acts on the ramp groove of the end locking mechanism 503. When the electromagnetic drive component 604 is energized, the linkage push rod 605 is advanced, and the wedge-shaped top block is embedded in the ramp groove, which pushes the rotating lock tongue to deflect counterclockwise to unlock.

[0073] The separation component 603 has a built-in preloaded spring that provides a reverse reset thrust. An anti-rebound claw is added to the side of the rotating latch. When the latch deflects to the unlocking angle, the claw automatically engages with the side wall groove to form a secondary lock. When the end locking mechanism 503 unlocks, the honeycomb unit group 2 falls away from the circumferential limiting component 502 under the action of gravity. The support frame 305 of the flexible connector 3 extends synchronously to maintain a linear posture. The ventilated adjustment plate 205 of the honeycomb body 201 controls the airflow to ensure that the connector degrades and separates quickly after landing.

[0074] The buffer landing mechanism 4 provides cushioning during the descent of the bee ball unit group 2, preventing the bee ball 201 from accidentally breaking upon landing and affecting the survival rate of the Trichogramma bees. The umbrella-shaped structure 401 operates on the same principle as a parachute, increasing air resistance upon deployment and thus providing cushioning for the descent of the bee ball unit group 2. One end of the trigger pull rope 402 is fixed to the bee ball 201 at the very end of the bee ball unit group 2, and the other end is connected to the restraint mechanism of the folded umbrella-shaped structure 401. When the bee ball unit group 2 detaches from the winding device 5 and falls, the trigger pull rope 402 is pulled by gravity, first breaking the restraint strap of the umbrella-shaped structure 401 to release it from its folded state. Then, under the action of air resistance, the umbrella-shaped structure 401 automatically unfolds, thereby increasing wind resistance, slowing down the descent speed of the bee ball unit group 2, and achieving a cushioned landing. This process is achieved entirely through mechanical linkage and requires no additional control unit.

[0075] Example 2

[0076] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 9 As shown below, see details:

[0077] In a preferred embodiment, the flexible connector 3 is composed of multiple strands of biodegradable fiber bundles 301 arranged in a spiral interlacing manner to form a tubular body 302. Axially sliding links 303 are embedded within the tubular cavity. The links 303 are connected by ball joints 304 to form a support frame 305. A viscoelastic buffer medium 306 is filled between the outer surface of the support frame 305 and the inner wall of the biodegradable fiber bundles 301. Furthermore, radially limiting wing plates are provided at the ball joint 304 nodes of the support frame 305. The edges of the wing plates are covered with a low-friction coating and conform to the inner wall of the tubular body 302 to form a sliding guide. The viscoelastic buffer medium 306 is internally embedded with a shaped... The shape memory mesh is fixedly connected to the chain link 303. When the winding device 5 winds up the honeycomb unit group 2, the supporting frame 305 is subjected to radial pressure. The ball joint 304 drives the radial limiting wing plate to slide spirally along the inner wall of the tubular body 302, forcing the shape memory mesh to undergo torsional deformation and store elastic potential energy. During the release and falling process, the mesh returns to its original shape, pushing the chain link 303 to extend axially, and simultaneously pulling the radial limiting wing plate to unfold and form rigid support. At the same time, the viscoelastic buffer medium 306 generates a shear thickening effect when the mesh is torsional deformed, enhancing the compressive strength in the winding state. When the mesh recovers its extension, it turns into a viscous flow state to reduce the sliding resistance of the frame. This linkage structure triggers the rigid-flexible conversion of the frame through the switching between winding and release states. The deformation recovery of the shape memory mesh, together with the rheological characteristics change of the buffer medium, realizes dual-modal adaptive adjustment of compact folding during winding and rapid straightening during release.

[0078] In a preferred embodiment, the flexible connector 3 is fixedly connected to a plug 307 at one end. The plug 307 has a radial groove 308 on its sidewall. The honeycomb ball 201 has connecting bases 203 at both ends. A rotatable locking sleeve 204 is embedded in each connecting base 203. The radial groove 308 engages with the locking sleeve 204 to achieve unidirectional rotational locking. Furthermore, a guide cone surface is added to the end of the plug 307, with a ball groove annularly arranged at the root of the cone surface and fitted with pressure-sensitive balls. A spiral protrusion is provided at a corresponding position on the inner wall of the locking sleeve 204, with the end of the spiral protrusion connecting to a locking cavity. When the plug 3... When the locking sleeve 204 is inserted axially, the guide cone surface squeezes the spiral protrusion, driving the locking sleeve 204 to rotate. The pressure-sensing ball slides into the locking cavity along the spiral protrusion trajectory to complete the radial engagement. At the same time, a separation spring is set inside the connecting base 203. The two ends of the spring press against the outer wall of the locking sleeve 204 and the end face of the connector 307, respectively. The pre-pressure direction of the spring is opposite to the spiral protrusion rotation direction. When the honeycomb unit group 2 falls off the winding device 5, gravity causes the connector 307 to have an axial displacement tendency. The separation spring releases the pre-pressure, pushing the locking sleeve 204 to rotate slightly in the opposite direction. The pressure-sensing ball disengages from the locking cavity and releases the radial constraint. This linkage structure automatically completes the locking through the spiral guidance during the insertion process. The gravity triggers the release of the pre-pressure of the separation spring during the fall to achieve self-unlocking, ensuring that the flexible connector 3 can be quickly degraded and separated after the honeycomb 201 lands.

[0079] In a preferred embodiment, the UAV mounting platform 1 is provided with a winding device 5, which includes a rotating shaft component 501, a circumferential limiting component 502, and an end locking mechanism 503. The bee ball unit group 2 is wound around the surface of the rotating shaft component 501, and the flexible connector 3 is wound synchronously with the bee ball 201. The circumferential limiting component 502 is used to constrain the bee ball unit group 2 in the wound state, and the end locking mechanism 503 is used to lock the end of the winding device 5. Further, the two ends of the rotating shaft component 501 are rotatably mounted on the UAV mounting platform 1 through bearings, and one end of it is provided with a locking groove or locking hole that cooperates with the end locking mechanism 503. The circumferential limiting component 502 is an arc-shaped or semi-circular constraint band or constraint frame that surrounds the outer periphery of the bee ball unit group 2 in the wound state, and its inner surface is provided with a shape that matches the outer contour of the bee ball 201. The groove or limiting block, the constraint strap or constraint frame is fixed at one end to the UAV mounting platform 1, and the other end is linked with the end locking mechanism 503. When the end locking mechanism 503 is in the locked state, its locking tongue or latch is inserted into the locking groove or locking hole at the end of the rotating shaft component 501 to prevent the rotating shaft component 501 from rotating. At the same time, the constraint strap or constraint frame of the circumferential limiting component 502 is tightly attached to the honeycomb unit group 2 to provide radial constraint to prevent loosening. When the end locking mechanism 503 is unlocked, its locking tongue or latch is withdrawn from the locking groove or locking hole of the rotating shaft component 501, releasing the rotation restriction on the rotating shaft component 501. At the same time, the constraint strap or constraint frame of the circumferential limiting component 502 is released in linkage, so that it is freed from the tight constraint on the honeycomb unit group 2. At this time, the honeycomb unit group 2 under the action of gravity drives the rotating shaft component 501 to rotate and unfold, and the flexible connector 3 and the honeycomb body 201 are released from the coiled state and fall.

[0080] In a preferred embodiment, the winding device 5 further includes:

[0081] The variable diameter guide groove module 504 is composed of two sets of coaxial radially expandable arc-shaped guide rails 505, and the inner surface of the arc-shaped guide rails 505 is provided with staggered limiting protrusions 506.

[0082] The pitch adjuster 507 includes a worm gear disc 508 and a meshing worm gear adjusting mechanism 509;

[0083] The movable end of the arc-shaped guide rail 505 is hinged to the worm gear disk 508. Furthermore, the input end of the worm gear adjustment mechanism 509 is connected to the output shaft of a servo motor, and the output shaft compensates for coaxiality deviation through a floating coupling. An annular ratchet groove is formed on the edge of the worm gear disk 508, and a pressure-adaptive pawl is provided at the movable end of the arc-shaped guide rail 505. The pawl is pre-compressed by a disc spring and tightly fits against the ratchet groove tooth surface. When the worm gear adjustment mechanism 509 drives the worm gear disk 508 to rotate, the pawl engages and displaces step-by-step along the ratchet groove, synchronously pulling the two sets of arc-shaped guide rails 505 to extend and retract radially at equal intervals. A stroke buffer is provided at the end of the extension and retraction trajectory of the arc-shaped guide rail 505. The buffer has a reset spring embedded in it that contacts the hub of the worm gear disk 508, absorbing inertial impact when the guide rail retracts. An elastic filler block is embedded at the root of the limiting protrusion 506, and the filler block automatically compensates for the gap width of the protrusion as the guide rail extends and retracts radially. This linkage structure achieves synchronous diameter change of the guide rail through the rigid transmission of ratchet teeth and pawls, the floating coupling eliminates assembly error interference, and the elastic filler block maintains the continuous wrapping constraint of the honeycomb unit group 2 during the winding process.

[0084] In a preferred embodiment, the UAV mounting platform 1 is further provided with a release control module 6, the release control module 6 comprising:

[0085] The frame support component 601 is rigidly connected to the UAV mounting platform 1;

[0086] The unlocking unit 602 is integrated into the frame support component 601;

[0087] Separation component 603 connecting the unlocking unit 602 and the end locking mechanism 503;

[0088] The unlocking unit 602 controls the end locking mechanism 503 to switch from a locked state to an unlocked state via the separation component 603. When the end locking mechanism 503 is in the unlocked state, the bee ball unit group 2 is released from the constraint of the circumferential limiting component 502 and falls under the action of gravity. Furthermore, the unlocking unit 602 includes an electromagnetic actuator and a push rod linked thereto. One end of the push rod is hinged to the output end of the electromagnetic actuator, and the other end passes through the separation component 603 and abuts against the locking tongue of the end locking mechanism 503. The separation component 603 is provided with a guide for the push rod to move axially. The linear guide rail has a limiting boss on its inner wall to limit the rotation angle of the push rod. When the electromagnetic driver is energized and retracts, it drives the push rod to move axially along the linear guide rail, pushing the locking tongue to retract inward against the elastic force of its return spring, so that the front end of the locking tongue is released from the buckle constraint on the end of the winding device 5. The end locking mechanism 503 switches from the locked state to the unlocked state. At this time, the honeycomb unit group 2 driven by gravity drives the winding device 5 to rotate. The flexible connector 3 and the honeycomb body 201 are released and unfolded from the winding state. The honeycomb unit group 2 as a whole is released from the constraint of the circumferential limiting component 502 and begins to fall.

[0089] In a preferred embodiment, the unlocking unit 602 includes an electromagnetic drive assembly 604 and a linkage push rod 605. One end of the linkage push rod 605 is hinged to the electromagnetic drive assembly 604, and the other end passes through the separation assembly 603 and acts on the end locking mechanism 503 to unlock it. Further, the linkage push rod 605 has a double guide sleeve in the middle, with a self-lubricating bushing fitted into the inner wall of the sleeve to form an axial sliding pair. The end of the push rod is machined into a wedge-shaped top block. The end locking mechanism 503 has a rotating locking tongue inside, with a ramp groove on the bottom surface of the locking tongue that matches the wedge-shaped top block. When the electromagnetic drive assembly... When 604 is energized, the linkage push rod 605 advances axially along the sliding sleeve, and the wedge-shaped top block embeds into the ramp groove, pushing the rotating locking tongue to deflect counterclockwise, releasing the lock on the end of the winding device 5. At the same time, the separation component 603 has a built-in preload spring, with both ends of the spring abutting against the limiting boss of the linkage push rod 605 and the housing of the separation component 603, respectively, providing a reverse reset thrust after the unlocking action is completed. An anti-rebound claw is added to the side of the rotating locking tongue. The claw is hinged to the base of the end locking mechanism 503 through a torsion spring. When the rotating locking tongue deflects to the unlocking angle, the claw automatically engages with the groove on the side wall of the locking tongue under the action of the torsion spring to form a secondary lock. This linkage structure achieves low-power unlocking through the force amplification and transmission of the wedge surface-slope, the double guide sliding sleeve eliminates the push rod sway, and the anti-rebound claw ensures that the locking mechanism is in a stable open state when the honeycomb unit group 2 is released.

[0090] In a preferred embodiment, the viscoelastic buffer medium 306 is covered with a directional sliding layer 309, which forms an axial sliding pair with the inner wall of the tubular body 302. Furthermore, the outer surface of the directional sliding layer 309 facing the inner wall of the tubular body 302 is provided with axially extending guide ribs. These guide ribs are embedded in corresponding axial grooves on the inner wall of the tubular body 302, restricting its circumferential rotation. Simultaneously, the inner surface of the directional sliding layer 309 facing the viscoelastic buffer medium 306 is tightly fitted with the medium and is provided with fixing ribs or rough textured structures to prevent relative sliding. When the flexible connector 3 is subjected to external force, causing the link 303 of the supporting frame 305 to slide axially or the ball joint 304 to rotate, the link 303 directly drives the viscoelastic buffer medium 306 to deform through its surface protrusions or grooves. The deformation force of the viscoelastic buffer medium 306 drives the directional sliding layer 309, which is fixed to it, to slide synchronously along the axial grooves on the inner wall of the tubular body 302, thereby achieving the transmission of buffering force and axial displacement compensation.

[0091] In a preferred embodiment, the end of the variable diameter guide groove module 504 is provided with a centrifugal anti-loosening mechanism 510. The centrifugal anti-loosening mechanism 510 includes a counterweight swing arm 511 and a reset spring 512. The swing end of the counterweight swing arm 511 can extend into the gap formed between adjacent limiting protrusions 506 under the action of centrifugal force. Furthermore, the root of the counterweight swing arm 511 is hinged to the module end base 514 through a pivot 513. A reset spring 512 providing reset force is installed near the pivot 513. A middle part or near the root of the swing arm is provided with a reset spring 512. The guide rail 515 limits the outward swing trajectory. When the variable diameter guide groove module 504 rotates with the rotating shaft component 501 and generates centrifugal force, the counterweight swing arm 511 overcomes the elastic force of the reset spring 512 and swings outward. The claw 516 with a specific shape at its end extends radially along the guide rail 515 and is precisely embedded in the gap between adjacent limiting protrusions 506 to form a mechanical lock, preventing the winding body from loosening. When the rotation stops, the reset spring 512 pulls the counterweight swing arm 511 to rotate, so that the claw 516 completely disengages from the gap of the limiting protrusions 506 and releases the lock.

[0092] In a preferred embodiment, the surface of the bee sphere 201 is provided with an openable and closable air-permeable adjustment plate 205. The air-permeable adjustment plate 205 is made of biodegradable material and is staggered with the channel structure 202. Further, the air-permeable adjustment plate 205 is connected to the inner wall of the bee sphere 201 through a micro-hinged shaft, and a shape memory alloy sheet is sleeved at the end of the hinge shaft. A humidity-responsive push rod is provided inside the bee sphere 201, and the top of the push rod contacts the shape memory alloy sheet to form a linkage fulcrum. When the ambient humidity reaches a preset threshold, the humidity-responsive push rod extends axially to push the shape memory alloy sheet to deform, driving the air-permeable adjustment plate 205 to rotate and open around the hinge shaft. At the same time, a flow-guiding grid is provided at the edge of the channel structure 202, and the inclination angle of the grid forms an airflow guiding angle with the open air-permeable adjustment plate 205. During the descent of the bee sphere 201, the open air-permeable adjustment plate 205 and the flow-guiding grid work together to change the airflow path, so that the external airflow is introduced into the bee sphere 201 along the tangential direction of the channel structure 202. This linkage structure triggers the directional opening and closing of the breathable adjustment plate 205 through environmental parameters, and works with the flow guide grid to form a swirling ventilation, which not only accelerates the escape response of the Trichogramma wasp, but also avoids the humidity overload inside the sphere when it falls.
