Description

Technical Field

[0001] This invention relates to the field of ecological monitoring and insect collection technology, specifically to a rainproof modular insect trap. Background Technology

[0002] Insect traps are passive or active collection devices designed to utilize insects' attraction to stimuli such as light, shape, or odor. They play an important role in ecological research, agricultural pest monitoring, and biodiversity surveys. Existing common insect traps include Mak's nets, light traps, and sticky insect boards, but these devices often have shortcomings in terms of waterproofing, rainproofing, and portability, making them difficult to operate stably for extended periods.

[0003] Traditional Marshall nets are large in size and complex to construct, and are easily restricted by rainfall, wind and terrain, making them unsuitable for continuous deployment in variable environments such as grasslands and forests. Light traps rely on electricity, which is energy-intensive and susceptible to light pollution, often resulting in the overcapture of non-target insects. Although some improved devices have improved capture efficiency, they still generally suffer from simple structures, inconvenient cleaning, complex installation and significant ecological disturbance, failing to meet the needs of long-term ecological monitoring and multi-point deployment.

[0004] Therefore, there is an urgent need for a new type of insect trapping device that is simple in structure, modularly disassembled and assembled, rainproof, and adaptable to diverse installation environments. This device can effectively prevent rainwater from entering the insect trapping unit and achieve stratified capture of lightweight and heavy insects, thereby improving capture efficiency and reducing environmental disturbance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rainproof modular insect trap with a simple structure that can be modularly disassembled and assembled, effectively enabling the layered capture of flying insects in the wild.

[0006] This invention provides a rainproof modular insect trap, comprising:

[0007] A bottom insect collector, wherein a lower insect guide tube is fixed to the top of the bottom insect collector, the upper end of the lower insect guide tube protrudes from the top of the bottom insect collector, and the lower end of the lower insect guide tube extends into the bottom insect collector;

[0008] A hydrophobic insect-guiding funnel is provided above the bottom insect collector, and the bottom of the hydrophobic insect-guiding funnel is provided with an insect-dropping interface that connects with the upper end of the lower insect-guiding tube.

[0009] A cross-shaped plate is disposed above the hydrophobic insect-guiding funnel, and the lower end of the cross-shaped plate is fixed inside the opening at the upper end of the hydrophobic insect-guiding funnel.

[0010] A rain cap, wherein the rain cap is placed above the cross-shaped plate and fixed to the upper end of the cross-shaped plate, and the top of the rain cap has an upward-protruding upper interface;

[0011] The top insect collector is located above the rain cap. The bottom of the top insect collector is provided with an upper insect guide tube. The lower end of the upper insect guide tube protrudes from the bottom of the top insect collector and connects with the upper insect interface. The upper end of the upper insect guide tube extends into the top insect collector.

[0012] Furthermore, the bottom insect collector includes a bottom container and a top cover covering the top of the bottom container, and the lower insect guide tube passes through the top cover and is fixedly connected to it.

[0013] Furthermore, the bottom of the bottom container is provided with a drainage pipe, the lower end of which is connected to the outside of the lower side of the bottom container, the upper end of which extends into the bottom container and is provided with a drainage net, a gap is formed between the lower end of the lower insect guide tube and the upper end of the drainage pipe, and the vertical projection of the lower end of the drainage pipe is located within the range of the drainage net.

[0014] Furthermore, the lower part of the bottom container, located in the cavity between its inner wall and the drainage pipe, is provided with anti-corrosion liquid.

[0015] Furthermore, the cross plate includes two transparent plates, one of which has a latch at the bottom and the other has a latch at the top. Each transparent plate is cross-locked with the corresponding other transparent plate through the latch.

[0016] Furthermore, each of the transparent plates has a groove in the middle, and the snap-fit ​​extends to the groove. When the two transparent plates are snapped together in a cross shape, the grooves on the two transparent plates form a space for fixing the insect attractant.

[0017] Each of the transparent plates has two symmetrical threading holes on the upper and lower sides of the groove, which are located on both sides of the latch. Two fixing wires pass through the four threading holes on the upper side of the groove and the four threading holes on the lower side of the groove, respectively, to fix the two transparent plates that are cross-clamped together.

[0018] Furthermore, the four corners of the lower end of the cross plate are provided with first snap-fit ​​parts, and the upper opening of the hydrophobic insect-guiding funnel is provided with four first snap-fit ​​parts around it. Each first snap-fit ​​part and each first snap-fit ​​part are snap-fitted together in a one-to-one correspondence.

[0019] The four corners of the upper end of the cross plate are respectively provided with second locking parts, the rain cap is provided with an annular limiting ring, and four second locking grooves are provided around the annular limiting ring. Each second locking part and each second locking groove are engaged in a one-to-one locking fit.

[0020] Furthermore, the top insect collector includes a top container and a bottom cover covering the bottom of the top container, with the upper insect guide tube passing through and fixedly connected to the bottom cover.

[0021] Furthermore, the bottom insect collector is directly supported on the ground or supported on the ground via a leveling base;

[0022] The leveling base includes a support platform and multiple threaded adjustable legs located at the bottom of the support platform. The bottom insect collector is used for positioning and supporting on the support platform, and each of the threaded adjustable legs is used for supporting on the ground.

[0023] Furthermore, the upper side of the rain cap is provided with at least two hanging rings around its center, which are used to connect a hanging rope or hook during hanging installation.

[0024] The beneficial effects of this invention are reflected in:

[0025] The insect trap of the present invention consists of several parts, including a bottom insect collector, a hydrophobic insect funnel, a cross-shaped plate, a rainproof cap, and a top insect collector. The structure is modular, simple, and can be disassembled and assembled in a modular manner, making it convenient for disassembly and assembly, transportation, and installation.

[0026] In use, insects are lured to the cross-shaped plate. Heavier insects collide with the plate and fall into the hydrophobic insect-guiding funnel. They then enter the bottom insect collector through the lower guide tube, thus capturing the heavier insects. Lighter insects, due to their lighter weight, do not fall upon impact with the plate. Instead, driven by their flight instincts and airflow, they actively choose to rise along the plate and enter the top insect collector through the upper guide tube, thus capturing the lighter insects. Therefore, this invention achieves stratified insect capture, with lighter insects guided to the top collector and heavier insects falling into the bottom collector, resulting in highly representative samples.

Detailed Implementation

[0045] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0046] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0047] This invention provides a rainproof modular insect trap, such as... Figures 1-2 As shown, the insect trap includes a bottom insect collector 100, a hydrophobic insect-guiding funnel 200, a cross-shaped plate 300, a rain cap 400, and a top insect collector 500.

[0048] Reference Figure 3 and Figure 4 The bottom insect collector 100 has a lower insect guide tube 110 fixed to its top. The upper end of the lower insect guide tube 110 protrudes from the top of the bottom insect collector 100, and the lower end of the lower insect guide tube 110 extends into the bottom insect collector 100. The bottom insect collector 100 is used to collect heavy insects, which can enter the bottom insect collector 100 through the lower insect guide tube 110.

[0049] To facilitate opening the bottom insect collector 100, the bottom insect collector 100 includes a bottom container 120 and a top cover 130 covering the top of the bottom container 120. The lower insect guide tube 110 passes through the top cover 130 and is fixedly connected to it. The top cover 130 and the bottom container 120 can be connected by means of threads, snaps, or direct clamping.

[0050] Preferably, the bottom of the bottom container 120 is provided with a drainage pipe 140, the lower end of the drainage pipe 140 is connected to the outside of the lower side of the bottom container 120, the upper end of the drainage pipe 140 extends into the bottom container 120 and is provided with a drainage net 141, a gap is formed between the lower end of the lower insect guide tube 110 and the upper end of the drainage pipe 140, and the vertical projection of the lower end of the drainage pipe 140 is located within the range of the drainage net 141.

[0051] When rainwater enters the bottom container 120 through the lower insect guide tube 110, it can directly pass through the drainage net 141 at the upper end of the drainage pipe 140 and flow out of the bottom container 120. When heavy insects enter the bottom container 120 through the lower insect guide tube 110, the drainage net 141 can prevent heavy insects from entering the drainage pipe 140. Insects that fall onto the drainage net 141 can crawl into the bottom container 120 through the gap between the lower insect guide tube 110 and the drainage pipe 140. Through this design, insects and water can be separated, and heavy insects collected in the bottom container 120 can be prevented from being soaked by rainwater.

[0052] The lower part of the bottom container 120, located in the chamber between its inner wall and the drainage tube 140, contains a preservative solution. This preservative solution is used to kill and preserve insect samples, prevent decay, and maintain the sample's morphology. The preservative solution can be a mixture of alcohol and glycerin in a 3:1 ratio.

[0053] In one specific embodiment, the bottom insect collector 100 is a semi-transparent PP tank with a volume of approximately 1.5L, a bottom diameter of 190mm, and a height of 190mm. The top cover 130 has a central opening for installing the lower insect guide tube 110. The lower insect guide tube 110 is made of PVC pipe, passes through the opening in the top cover 130, and is sealed with adhesive between the opening and the opening edge. The bottom container 120 has an opening at its bottom for installing a drain pipe 140. The drain pipe 140 is also made of PVC pipe, passes through the opening at the bottom of the bottom container 120, and is sealed with adhesive between the opening and the opening edge. The drain pipe 140 is aligned with the lower insect guide tube 110, and the diameter of the drain pipe 140 is larger than that of the lower insect guide tube 110 to ensure that all water flowing in through the lower insect guide tube 110 can be discharged through the drain pipe 140.

[0054] Reference Figure 5 and Figure 6 The hydrophobic insect-guiding funnel 200 is located above the bottom insect collector 100. The bottom of the hydrophobic insect-guiding funnel 200 is provided with an insect-dropping interface 210 that connects with the upper end of the lower insect-guiding tube 110. The lower insect-guiding tube 110 and the insect-dropping interface 210 can be connected by means of threads, snaps, or direct clamping.

[0055] The hydrophobic insect-guiding funnel 200 is made of black ABS plastic, with an outer diameter of 33cm and a total height of 14cm. The inner wall of the funnel 200 has a smooth, conical flow-guiding surface at a 45° angle, allowing rainwater and insects to slide smoothly down the wall. The outer edge of the funnel 200 has small drainage holes to further enhance its hydrophobic properties.

[0056] To prevent leakage between the insect lowering interface 210 and the lower insect guide tube 110, a waterproof rubber ring can be installed between the insect lowering interface 210 and the lower insect guide tube 110.

[0057] Reference Figure 7 and Figure 8 The cross-shaped plate 300 is positioned above the hydrophobic insect-guiding funnel 200, and the lower end of the cross-shaped plate 300 is fixed inside the opening at the upper end of the hydrophobic insect-guiding funnel 200.

[0058] The cross-shaped plate 300 includes two transparent plates 310, which can be made of transparent acrylic sheets. Each acrylic sheet is 2.5mm thick and has dimensions of 33.6cm × 60cm. One transparent plate 310 has a latch 311 at its lower part, and the other transparent plate 310 has a latch 311 at its upper part. Each transparent plate 310 is cross-shaped and interlocked with the corresponding other transparent plate 310 through the latch 311.

[0059] Two transparent plates 310 intersect vertically to form a four-way flight barrier, effectively preventing insects from flying horizontally and causing them to move vertically. Lighter insects will fly upwards into the top insect collector 500 due to their flight instinct and the airflow, while heavier insects will slide down along the hydrophobic insect funnel 200 due to inertia and gravity, thus achieving natural stratified capture.

[0060] Each transparent plate 310 has a groove 312 in the middle, and the snap 311 extends to the groove 312. When two transparent plates 310 are cross-shaped and snapped together, the groove 312 on the two transparent plates 310 forms an insect attractant fixing space 320. When in use, an insect attractant can be placed in the insect attractant fixing space 320 to attract insects.

[0061] Each transparent plate 310 has two symmetrical wire holes 313 on the upper and lower sides of the groove 312, which are located on both sides of the latch 311. Two fixing wires pass through the four wire holes 313 on the upper side of the groove 312 and the four wire holes 313 on the lower side of the groove 312 to fix the two transparent plates 310 that are cross-locked.

[0062] To facilitate the detachable connection between the cross plate 300 and the hydrophobic insect-guiding funnel 200, the four corners at the lower end of the cross plate 300 are provided with first snap-fit ​​parts 314, and the upper opening of the hydrophobic insect-guiding funnel 200 is provided with four first snap-fit ​​parts 220. Each first snap-fit ​​part 314 and each first snap-fit ​​part 220 are matched and engaged in a one-to-one manner.

[0063] Reference Figure 9 and Figure 10 The rain cap 400 is placed above the cross plate 300 and fixed to the upper end of the cross plate 300. The top of the rain cap 400 is provided with an upward protruding upper interface 410.

[0064] The rain cap 400 is made of black ABS plastic, with a diameter of 48cm and a thickness of 0.5cm. It has a central opening for attaching an insect mount 410, which is made of PVC tubing that passes through the opening and is sealed with adhesive. The rain cap 400 is conical in shape with a streamlined outer edge to prevent water accumulation and allow water to slide off along the edge.

[0065] To facilitate the detachable connection between the cross plate 300 and the rain cap 400, the four corners of the upper end of the cross plate 300 are provided with second locking parts 315. The rain cap 400 is provided with an annular limiting ring 420, which fits against the upper edge of the cross plate 300 to ensure the stability of the overall structure. The annular limiting ring 420 is provided with four second locking slots 421 around its perimeter. Each second locking part 315 and each second locking slot 421 are engaged in a one-to-one locking fit.

[0066] Reference Figure 11 and Figure 12 The top insect collector 500 is located above the rain cap 400. The bottom of the top insect collector 500 has an upper insect guide tube 510. The lower end of the upper insect guide tube 510 protrudes from the bottom of the top insect collector 500 and connects with the upper insect interface 410. The upper end of the upper insect guide tube 510 extends into the top insect collector 500. The upper insect guide tube 510 and the upper insect interface 410 can be connected by threads, snaps, or direct clamping.

[0067] To facilitate opening the top insect collector 500, the top insect collector 500 includes a top container 520 and a bottom cover 530 covering the bottom of the top container 520. The upper insect guide tube 510 passes through the bottom cover 530 and is fixedly connected to it. The top container 520 and the bottom cover 530 can be connected by means of threads, snaps, or direct clamping.

[0068] The top insect collector 500 is a transparent PP bottle with high transparency, allowing for direct observation of insect capture. The top insect collector 500 has a volume of approximately 1000mL, a base diameter of 110mm, and a height of 138mm. A 5cm diameter hole is cut into the bottom cap 530 for installing the upper insect guide tube 510. The upper insect guide tube 510 is made of PVC pipe, passes through the hole in the bottom cap 530, and is sealed with glue at the edge of the hole. The upper insect guide tube 510 is inserted into the top container 520 to a depth of approximately 1.5cm.

[0069] Reference Figures 13-15 The bottom insect collector 100 is supported directly on the ground or via a leveling base 600. The leveling base 600 includes a support platform 610 and multiple threaded adjustable legs 620 located at the bottom of the support platform 610. The bottom insect collector 100 is positioned and supported on the support platform 610, and each threaded adjustable leg 620 is supported on the ground, allowing the height of each threaded adjustable leg 620 to be rotated and adjusted.

[0070] like Figure 13 As shown, when the ground is flat, the bottom insect collector 100 can be directly installed on the ground. Multiple pull ropes 710 are connected around the rain cap 400, and the other end of each pull rope 710 is fixed by ground nails 720, which can play a role in preventing tipping.

[0071] like Figure 14 and Figure 15 As shown, when the ground is uneven, a detachable leveling base 600 can be installed below the bottom insect collector 100 to keep the insect catcher level on uneven ground.

[0072] The leveling base 600 can be triangular, cross-shaped, or ring-shaped, made of metal or high-strength plastic, and is fixedly connected to the bottom insect collector 100 via a slot. The height of the leveling base 600 is preferably 10-15cm to avoid grass or water accumulation affecting the capture effect. This installation method is suitable for deployment in grasslands, wetlands, and plains, offering high stability and convenient maintenance.

[0073] Reference Figure 16 The rain cap 400 has at least two hanging rings 430 around its center on the upper side, which are used to connect the hanging rope 800 or hook during hanging installation.

[0074] When the insect trap is used for hanging installation, a hanging rope 800 or hook can be connected to a hanging ring 430 on the rain cap 400 to suspend the insect trap on a support pole or tree branch. The hanging height is preferably 1.2 to 1.5 meters above the ground to ensure that the insect trap is subjected to vertical force. During installation, ensure that the insect trap is kept vertical to prevent rainwater from flowing back in due to tilting. This method is suitable for environments under forests, in shrubbery, or in experimental sheds, and can effectively reduce ground disturbance and improve capture efficiency.

[0075] Ground-based and suspended deployment methods can be used alternately according to terrain conditions to form a standardized deployment system that meets the insect monitoring needs in diverse ecological environments.

[0076] The steps for using this embodiment are as follows: ① Assemble the modules together according to the design; ② Place the insect trap on the ground or hang it on a support pole or tree branch; ③ Add preservative solution to the bottom insect collector 100; ④ Take a sample once a week, unscrew the bottom insect collector 100 to replace the preservative solution and collect the sample; ⑤ Clean it and reinstall it for continued use.

[0077] The insect trap in this embodiment consists of several parts: a bottom insect collector 100, a hydrophobic insect-guiding funnel 200, a cross-shaped plate 300, a rainproof cap 400, and a top insect collector 500. The structure is modular, simple, and can be disassembled and assembled in a modular manner, making it convenient for disassembly and assembly, transportation, and installation.

[0078] In this embodiment, insects are induced to the cross-shaped plate 300. Heavier insects collide with the cross-shaped plate 300 and fall downwards into the hydrophobic insect-guiding funnel 200. They then enter the bottom insect collector 100 through the lower insect-guiding tube 110, thus capturing the heavier insects. Lighter insects, due to their lighter weight, do not fall when they collide with the cross-shaped plate 300. Instead, driven by their flight instincts and airflow, they actively choose to rise along the cross-shaped plate 300 and enter the top insect collector 500 through the upper insect-guiding tube 510, thus capturing the lighter insects. Therefore, this invention can achieve stratified insect capture, with lighter insects guided to the top insect collector 500 and heavier insects falling into the bottom insect collector 100, resulting in highly representative samples.

[0079] Understandably, in order to further attract lightweight insects into the top insect collector 500, the insects' phototaxis can be utilized by setting up a light source inside the top insect collector 500.

[0080] This embodiment has excellent rainproof performance. The double-layer structure of the rain cap 400 and the hydrophobic funnel effectively prevents rainwater from entering.

[0081] The materials used in each module of this implementation are PP, ABS, and acrylic, which are lightweight, low-cost, and highly weather-resistant.

[0082] This embodiment can be placed on the ground or suspended, adapting to various outdoor environments.

[0083] This embodiment has high overall transparency and minimal visual interference, making it suitable for long-term monitoring and scientific research.

[0084] In summary, this embodiment features a scientifically sound and rationally designed structure, high modularity, long service life, and adaptability to various environmental conditions. Its rainproof and insect-guided design significantly improves capture rate and sample integrity while reducing human interference. The insect trap is reusable, making it both economical and practical. Compared to existing technologies, this invention can efficiently capture flying insects in different ecosystems, offering advantages such as rainproofing, corrosion resistance, stratified capture, and reusability, making it suitable for long-term ecological monitoring and scientific research applications.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
