Description

Technical Field

[0001] This invention relates to the field of urban environmental management technology and forestry pest control, and in particular to an airflow-guided synergistic flocculant trapping device that combines natural wind guidance, flocculant retention, and flying insect attraction. Background Technology

[0002] Willow and poplar catkins are a common environmental problem in northern Chinese cities during the spring, affecting not only air quality and residents' lives but also posing a fire hazard. Meanwhile, the ash-narrow-toothed beetle, a devastating borer, is widely distributed in North China. These borers, along with other tree-boring insects, can damage ash trees and other garden trees, impacting urban green landscapes and forest health.

[0003] Existing technologies for controlling willow and poplar catkins mainly include methods such as water spraying, pruning, chemical injection, active adsorption, or passive collection using interception nets. Existing patents for willow and poplar catkin collection devices mainly include: a handheld willow and poplar catkin collection tube using a fan for adsorption (patent application number: CN202610035145.8); a vertical mesh device using an interception net for passive collection of willow and poplar catkins (patent application number: CN202610272013.7); a box-type device using a fan to adsorb willow and poplar catkins and centrally incinerate them (patent application number: CN202511811406.2); and a vehicle-mounted device for autonomously cleaning and collecting willow catkins from roads (patent application number: CN202420987585.X). The above patents can collect flying catkins, but they mainly rely on active adsorption or subsequent cleaning and utilization. They do not arrange the catkin collection area and the target flying insect attraction path in a continuous structure, and cannot achieve the synergistic effect of high-quality landscape effect, safety and portability, insect control, cleaning and utilization of willow catkins.

[0004] Existing methods for trapping flying insects mostly employ bait boxes, lures, sticky traps, or net cages. Existing technologies also include trapping devices for target flying insects such as the ash-necked jewel beetle, including: an ash-necked jewel beetle trap and trapping method, which uses yellow-green components and sticky glue to attract and trap adult insects (patent application number: CN106489867A); and an ash-necked jewel beetle trap, which uses a green sticky trap, lure, or attractant for trapping (patent application number: CN209376508U). These trapping devices primarily rely on color, lures, attractants, or adhesive structures to trap and kill flying insects, without considering the use of natural wind to collect drifting pollen, nor establishing a coordinated trapping path involving wind guidance and aggregation, comb-like trapping of pollen, insect passage, and secondary interception by net cages.

[0005] For scenarios such as communities, parks, pedestrian streets, and courtyards, devices that rely solely on fan adsorption often suffer from energy consumption and maintenance issues. Simple interception net structures are prone to clogging or are affected by wind direction, and traditional insect-attracting devices struggle to utilize the floating pollen to create a physical structure conducive to trapping insects. Therefore, there is an urgent need for a device that is relatively simple in structure, easy to maintain, and capable of utilizing natural wind to guide the flow and achieve the coordinated capture of floating pollen and flying insects. Summary of the Invention

[0006] The purpose of this invention is to provide an airflow-guided synergistic flocculant trapping device to solve the problems of existing flocculant trapping and flying insect trapping devices having relatively simple functions, insufficient synergy, and poor adaptability to lightweight application scenarios.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An airflow-guided synergistic trapping device for worms includes a support frame, a central worm-attracting zone located in the middle of the support frame, and multiple airflow-guided trapping units arranged circumferentially around the central worm-attracting zone. The central worm-attracting zone includes an adhesive net cage 5 and a target insect attractant box 6 located in the inner cavity or central region of the adhesive net cage 5; each airflow-guided trapping unit includes a concave curved airflow guide plate 3 and a trapping comb 4.

[0008] The flow-guiding and trapping unit includes at least one flow-guiding plate 3 with a concave curved surface. The flow-guiding plate 3 is radially and uniformly distributed around the central insect-attracting area, and its concave surface points towards the central insect-attracting area. The guide vane 3 is in the shape of a flat teardrop, with its large end facing outward and its small end pointing towards the central insect-attracting area; the blade has a concave wind-gathering surface, and the curvature of the concave surface gradually increases from the large end to the outer edge and then to the small end. It utilizes the Coanda effect to smoothly converge the horizontal airflow to the central area, and at the same time utilizes the Venturi effect to accelerate the airflow in the narrow channel between the blades, so that the natural wind carries the floating catkins to the central side and converges and passes through the collecting comb 4.

[0009] Furthermore, the trapping comb 4 is located between the concave curved guide plate 3 and the adhesive net cage 5, with the comb teeth of the trapping comb 4 extending into or adjacent to the outlet airflow path of the guide channel; the adhesive net cage 5 is disposed on the central side of the trapping comb 4, and a gap is formed between the adhesive net cage 5 and the trapping comb 4. The trapping comb 4 and the adhesive net cage 5 are sequentially located on the outer periphery of the target flying insect attractant box 6.

[0010] Through the above structure, the natural wind entering the device first converges to the collecting comb 4 through the guide channel. The floating fluff is entangled on the collecting comb 4 and forms a fluff collection area. After being attracted by the attractant box 6, the target flying insects fly from the periphery to the center. Their attraction path passes through the fluff collection area and the adhesive net cage 5 in sequence, so that the fluff entanglement, the attraction of flying insects and the secondary interception of missed objects form a continuous combination.

[0011] Furthermore, the trapping comb 4 includes multiple comb teeth arranged circumferentially or radially along the central insect-attracting area. The surface of the comb teeth is provided with barbs, grooves or rough retention structures to trap the floating fluff that enters with the airflow and form a fluff trapping area.

[0012] Furthermore, the adhesive net cage 5 is a cage-like structure with mesh openings, and an adhesive layer is provided on its outer surface, inner surface, or mesh structure to perform secondary interception of fine floating catkins and missed flying insects after passing through the trapping comb 4.

[0013] Furthermore, the target insect attractant box 6 is a ceresin narrow-necked jelly attractant box, and is equipped with a release hole or a slow-release structure.

[0014] Furthermore, it also includes an intelligent control system, which comprises a solar panel, an image sensor, and a micro servo motor; The solar panels are mounted on top of the device to provide power to the entire system; The image sensor is a wide-angle miniature camera, installed below the solar panel, used to monitor the lint load on the comb in real time; The micro servo motor is connected to the guide vane and is used to adjust the angle of the guide vane according to the monitoring data of the image sensor.

[0015] Furthermore, the image sensor can distinguish between willow catkins and adult ash beetles attached to the comb teeth, and classify, count, and store the data. When the amount of catkins is low, a signal is sent to the micro servo motor to open the air inlet of the guide vane to increase the amount of catkins trapped. When the catkins are overloaded, the guide vane on one side is closed to prevent the catkins from being blown off by the wind. When the amount of catkins captured is high, indicating a high density of insects in the surrounding area, the concentration of pheromone release is adjusted as needed.

[0016] Furthermore, the device is shaped like a lantern and has a hanging ring at the top, allowing it to be suspended from facilities such as streetlights and utility poles at a height of not less than 2.2 meters.

[0017] Furthermore, the trapping comb and adhesive mesh cage are detachable, making them easy to clean and replace.

[0018] Compared with the prior art, the present invention has the following advantages: 1. In this invention, the flow channel, the trapping comb 4, the adhesive net cage 5, and the target insect attractant box 6 are arranged in a continuous path from the outer periphery to the center, so that the capture of drifting catkins and the attraction of flying insects are no longer simple parallel structures, but form a synergistic capture path of flow channeling and aggregation, catkin storage by the comb, insect attraction and secondary interception by the net cage.

[0019] 2. The trapping comb 4 is located at the center side outlet of the flow channel, which can preferentially trap large clumps of floating fluff that enter with the airflow and form a fluff trapping area. This fluff trapping area is located on the path of the flying insects, which helps to increase the chances of the flying insects coming into contact with the fluff, comb teeth and adhesive structures.

[0020] 3. The adhesive net cage 5 and the trapping comb 4 are set separately with gaps between them, which can intercept the fine floating catkins and missed flying insects that pass through the trapping comb 4, and reduce the risk of blockage on a single interception surface.

[0021] 4. The device can utilize natural wind to guide and collect floating fluff, reducing reliance on external power fans; the collecting comb 4, adhesive net cage 5, and target insect bait box 6 can be detachable for easy cleaning and maintenance.

[0022] 5. The device can achieve positive feedback in the synergistic control of willow catkins and insects. It uses ash pheromone pheromone to attract pests to the vicinity of the device, where the pests are entangled by willow catkins that are pre-wrapped on the comb. The trapped insects then form new blocking structures, further improving the efficiency of intercepting the drifting catkins and creating a positive feedback loop of "willow catkins entangle insects - insects help trap catkins".

[0023] 6. The device can be further integrated with solar panel 1, image sensor 2, control module and guide vane drive mechanism to monitor the lint load in real time and intelligently adjust the angle of the guide vane, and adjust the lint storage amount and pheromone release concentration as needed to achieve precise control.

[0024] 7. The device is shaped like a lantern, with the guide vanes designed in the form of biomimetic petals. It closes like a bud when there is no wind and opens when there is wind, creating a dynamic aesthetic. It can be used as a community landscape feature. It can be hung on existing facilities such as streetlights and utility poles, and is suitable for lightweight scenarios such as communities, parks, pedestrian streets, and courtyards where existing equipment is difficult to cover.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, this embodiment provides an airflow-guided synergistic trapping device for lint, which is shaped like a spherical lantern with a diameter of 500mm. It can be suspended from facilities such as streetlights, utility poles, and trees by means of hanging rings, or it can be installed by means of poles, brackets, or wall fixation, depending on the usage scenario.

[0029] The device mainly consists of a central insect-attracting area and six flow-guiding and trapping units distributed around it. Each flow-guiding and trapping unit contains four concave curved flow-guiding plates. The four flow-guiding plates are evenly distributed radially around the central insect-attracting area, forming a double-layer back-to-back structure.

[0030] The guide vane 3 is flat and teardrop-shaped, with its larger end facing outward and its smaller end pointing towards the central insect-attracting area. The blade has a concave wind-gathering surface, and the curvature of the concave surface gradually increases from the larger end towards the outer edge and towards the smaller end. This design utilizes both the Coanda effect and the Venturi effect: when natural wind comes into contact with the concave surface of the blade, the Coanda effect causes the airflow to adhere to the curved wall and flow, instead of dissipating directly. It is "caught" by the concave structure and converges towards the central insect-attracting area. Meanwhile, the narrowing channel between the blades forms a Venturi tube structure, and the airflow speeds up when it squeezes from the wide inlet into the narrowing gap, carrying the willow catkins at high speed towards the central trapping comb 4.

[0031] The central insect-attracting area includes a trapping comb 4, a sticky net cage 5, and a target flying insect attractant box 6 located in the center of the sticky net cage.

[0032] The collecting comb 4 consists of multiple sets of radially distributed comb teeth. The tips of the comb teeth do not extend beyond the inner edge of the guide plate 3. The surface of the comb teeth is provided with small barbs and grooves, which can effectively entangle and retain willow catkins. The collecting comb 4 has a detachable structure, and the number of comb teeth can be increased or decreased as needed, and it is also easy to clean and replace.

[0033] The adhesive net cage 5 is located inside the collecting comb 4, with a certain gap between it and the collecting comb 4, forming a two-layer interception structure of "comb teeth-net cage": the wind speed is faster at the collecting comb 4, which is used to intercept large clumps of willow catkins and larger insects; the wind speed is slower at the adhesive net cage 5, which is used to intercept the remaining small catkins and small flying insects that escaped capture. This design is not easy to clog and greatly improves the capture efficiency.

[0034] The target insect attractant box 6 is positioned at the center of the adhesive net cage 5. Its purpose is to attract adult white wax jewel beetles to the vicinity of the device. The attracted insects will crash into or actively burrow into the complex mesh environment composed of "toothed combs + flying catkins" on the outside, and become entangled and trapped by this physical structure. The insects die outside, mixed with the willow catkins, and can be disposed of together during cleaning, which is very convenient.

[0035] like Figure 5 As shown, the device can also be equipped with an intelligent control component. The intelligent control system consists of a solar panel 1, an image sensor 2, and a miniature servo motor. The solar panel 1 is installed on the top of the device, providing power to the entire system and enabling zero-energy operation. The image sensor 2 is a wide-angle miniature camera, installed below the solar panel 1, capable of monitoring the lint load on the collecting comb 4 from all angles in 360 degrees.

[0036] Image sensor 2 has the following functions: 1. Differentiate whether the adhering material on the comb teeth is willow catkins or white wax beetle adults, and classify, count and store them; 2. Real-time monitoring of fluff quantity: When the fluff quantity is low, a signal is sent to the micro servo motor to open the air inlet of the guide vane 3 to deliberately trap more willow fluff and ensure that there is enough fluff to trap insects; when the fluff accumulation is overloaded, the guide vane 3 on one side is closed to prevent the fluff from being blown away by the strong wind. 3. Monitor insect population density: When the capture rate of white ash narrow jewel beetles is high, indicating a high insect population density in the surrounding area, adjust the concentration of pheromone release as needed; 4. When the comb tooth is full of worms, send a cleaning and replacement reminder.

[0037] The miniature servo motor is connected to the guide vane 3 and is used to precisely adjust the angle of the guide vane 3 according to the monitoring data of the image sensor 2, actively regulate the amount of filaments stored, and make reserves for insect trapping.

[0038] like Figure 6 and Figure 7 As shown, the workflow of this invention is as follows: 1. Natural winds enter the airflow trapping unit from all directions. The Coanda and Venturi effects cause the airflow to gather and accelerate, carrying willow catkins and flying insects towards the central insect-attracting area. 2. Airflow carrying catkins and insects impacts the trapping comb 4, initially intercepting and trapping large clumps of willow catkins and larger insects; 3. The pheromone attractant attracts vesicles from the periphery to the center. The insects are forced to fly through the filamentous area and are captured by the filamentous silk. 4. Fine flocs and missed insects adhere to the central adhesive net cage 5, achieving secondary interception; 5. Powered by solar panel 1, image sensor 2 uses a wide-angle camera to identify the morphology of caterpillars and monitor the load status; 6. Adjust the air intake volume by finely adjusting the angle of the guide vanes according to the load conditions, and send cleaning and replacement reminders.

[0039] In practical use, the number of flow-guiding and trapping units, the size of the flow-guiding plates, the density of the comb teeth, the mesh size of the net cage, and the type of attractant box can be adjusted according to the intensity of pollen generation, the species of target flying insects, the installation location, and landscape requirements. Multiple devices can be combined to form a wider-coverage control network as needed. In residential areas and areas with less pollen, its insect-killing function can be mainly utilized; in parks, communities, and other places, it can simultaneously play a role in pollen trapping and insect-killing, and the device itself can also serve as a landscape feature, achieving "unobtrusive control."

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
