Description

Technical Field

[0001] This invention belongs to the field of environmental monitoring technology, specifically an environmental protection monitoring device and monitoring method. Background Technology

[0002] Environmental protection refers to all actions taken by human beings to solve existing or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of the economy and society. In order to better achieve the purpose of environmental protection, accurately, timely and comprehensively reflect the current status and development trend of environmental quality, and provide scientific basis for environmental management, pollution source control and environmental planning, it is necessary to use environmental protection monitoring equipment to monitor the environment.

[0003] The environmental ecosystems to be tested include various insects, whose reproductive behavior is highly sensitive to environmental responses. Many insects require specific temperature, humidity, and light conditions to complete their reproductive process. Secondly, insects' food acquisition behavior is also an important aspect of their environmental response. Insects require specific foods to meet their growth and reproductive needs. Furthermore, insects' physiological adaptation mechanisms are also a form of response to the environment.

[0004] In order to collect the necessary data for environmental monitoring through insects, it is necessary to capture insects in the target environment. The common method is to use nets to capture insects. However, using nets to capture insects requires manual searching and capture one by one, which is a lot of work and requires a lot of manpower and time. At the same time, using nets to capture insects can also damage them, thus affecting the efficiency of capture.

[0005] Therefore, the present invention provides an environmental protection monitoring device and a monitoring method. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The environmental protection monitoring device and monitoring method of the present invention includes a supporting base plate, a container cylinder, a collection net, a supporting mechanism, a trapping mechanism and a sealing mechanism. The container cylinder is detachably installed on the upper end face of the supporting base plate. The collection net is slidably installed on the inner wall of the container cylinder. The collection net is a common stainless steel wire mesh. When capturing a target, the collection net is placed inside the container cylinder.

[0008] The bearing mechanism includes a bearing ring and a guide shaft. The bearing ring is fixedly installed on the outer wall of the receiving cylinder and is integrated with the receiving cylinder. The guide shaft is detachably installed on the upper end face of the bearing ring.

[0009] The trapping mechanism includes a protective cover and an information generator. The information generator is used to emit trapping information and is detachably installed on the inner wall of the supporting base plate. A PCB board is provided on the inner wall of the supporting base plate, and LED beads are integrated on the PCB board. The protective cover is fixedly installed on the upper surface of the supporting base plate. The protective cover is located above the information generator and is used to close the information generator and protect the LED beads. The protective cover extends into the interior of the receiving cylinder.

[0010] The sealing mechanism includes a sealing cover and a closing cover. The closing cover is detachably installed on the inner wall of the sealing cover. The sliding sealing cover controls the synchronous sliding of the closing cover. The sealing cover is elastically installed on the outer wall of the guide shaft. The guide shaft guides the sliding of the sealing cover. After the target enters the collection net, the elastic force on the sealing cover controls the sliding of the sealing cover until the closing cover seals the opening end of the collection net.

[0011] Preferably, a limiting ring for inserting a closing cover is fixedly installed on the inner wall of the collection net. After the closing cover is inserted into the limiting ring, the closing cover is fixed by friction. A sealing plate is detachably installed on the bottom surface of the supporting base plate. The sealing plate is connected to the supporting base plate by bolts, and a rubber pad is provided at the contact position between the sealing plate and the supporting base plate. A limiting frame is fixedly installed on the upper end face of the supporting base plate. An insertion plate for sliding insertion into the limiting frame is fixedly installed on the inner wall of the receiving cylinder. A groove for insertion of the insertion plate is opened on the side wall of the limiting frame. The bottom surface of the receiving cylinder is pressed against the upper end face of the supporting base plate. The receiving cylinder is rotated until the insertion plate is inserted into the limiting frame, realizing the detachable connection between the supporting base plate and the receiving cylinder. An absorption layer is provided on the upper end face of the supporting base plate. The absorption layer is located between the collection net and the supporting base plate and is used to absorb the feces discharged by the target.

[0012] Preferably, an installation plate is fixedly installed on the inner wall of the closed cover. The installation plate and the closed cover adopt an integrated structural design. A rubber nipple for insertion into the installation plate is fixedly installed on the upper end face of the closed cover. A through hole for insertion of the rubber nipple is opened on the outer wall of the closed cover.

[0013] The inner wall of the bearing ring is threaded with a connecting cylinder. The bottom end of the guide shaft is rotatably connected to the axial end of the connecting cylinder. Rotating the connecting cylinder connects the guide shaft and the bearing ring, so as to provide a trajectory for the sliding of the enclosure.

[0014] Preferably, a connecting ear plate is fixedly installed on the outer wall of the enclosure, and a guide shaft passes through the connecting ear plate and is slidably connected to it. The inner wall of the connecting ear plate is slidably fitted to the outer wall of the guide shaft. A connecting spring is fixedly connected to the bottom surface of the connecting ear plate, and the other end of the connecting spring is fixedly connected to the outer wall of the connecting shaft. The elastic force of the connecting spring pulls the enclosure in real time, so that the enclosure has a downward sliding tendency in real time. A hook plate for engaging with the connecting ear plate is elastically installed on the outer wall of the guide shaft. The hook plate is moved until it separates from the connecting ear plate. At this time, the elastic force of the connecting spring controls the sliding of the enclosure until the enclosure is engaged with the limiting ring, thereby achieving target capture.

[0015] Preferably, a support plate is detachably mounted on the outer wall of the guide shaft. A limit hook is provided on the upper end face of the support plate. The bottom of the limit hook is connected to the support plate by a rope to suspend the support plate at the target position. An installation block is fixedly mounted on the bottom surface of the support plate. A controller is fixedly mounted in the inner cavity of the installation block. The controller is a common electromagnet. A magnetic plate is elastically mounted on the inner wall of the installation block. A top pressure rod for pushing the hook plate is fixedly mounted on the other end of the magnetic plate. When the hook plate needs to be moved, the controller is energized to generate a magnetic field, which pushes the magnetic plate through magnetic force and pushes the hook plate to separate from the connecting ear plate through the top pressure rod, thereby releasing the sealing cover.

[0016] Preferably, a limit frame is provided on the upper end face of the support plate, and an installation cylinder is fixedly installed on the upper end face of the limit frame. A limit ring is slidably installed on the inner wall of the installation cylinder, and an elastic plate is fixedly installed on the bottom surface of the limit ring. The elastic plate is a common elastic plastic plate, and a conical block is fixedly installed on the other end of the elastic plate. Multiple elastic plates and conical blocks are provided and arranged in a ring. The inner wall of the conical block fits against the outer wall of the guide shaft, and the inclined surface of the conical block slides against the inner wall of the installation cylinder. A conical groove adapted to the conical block is opened on the inner wall of the installation cylinder. After the guide shaft is inserted, the sliding of the installation cylinder is unidirectionally limited.

[0017] Preferably, a top-pressure spring is fixedly installed on the inner wall of the mounting cylinder, and the other end of the top-pressure spring is fixedly connected to the outer wall of the limiting ring. The top-pressure spring pushes the limiting ring, so that the conical block tends to fit against the inner wall of the conical groove in real time. The outer wall of the limiting frame slides against the outer wall of the mounting cylinder, and the outer wall of the limiting ring is fixedly connected to the inner wall of the limiting frame. The sliding limiting frame controls the sliding of the limiting ring, so as to facilitate the separation of the conical block from the conical groove and facilitate the removal of the collection net.

[0018] A monitoring method using an environmental protection monitoring device, the method comprising the following steps:

[0019] A1. First, check the power supply of the information generator, and then insert the collection net into the inner cavity of the container.

[0020] A2. Adjust the support plate and the enclosure to slide into the outer wall of the guide shaft, hang the limit hook at the target location, and fix the support plate by the weight of the whole device and the conical block.

[0021] A3. Slide the closed cover until the hook plate and the connecting ear plate are engaged;

[0022] A4. Turn on the information generator to lure the target. After the target enters the collection net, push the hook plate and the connecting ear plate to separate by the top pressure rod. The closed cover and the closed cover slide down until the closed cover is inserted into the limit ring.

[0023] A5. Disassemble the guide shaft, separate the closure from the mounting plate, and finally remove the collection net with the closure inserted to complete the target capture and collection.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. This invention uses a protective cover and an information generator. The protective cover is located above the information generator and is used to seal the information generator. The protective cover extends into the interior of the container. When environmental protection monitoring is required, the information generator emits a trapping signal to lure the target into the inner cavity of the collection net from the upper end of the container. At the same time, a sealing cover and a closing cover are set. After the target enters the collection net, the elastic force of the sealing cover controls the sliding of the sealing cover until the closing cover seals the opening end of the collection net, thereby capturing the target, improving the efficiency of sample collection, and reducing the harm to the captured target.

[0026] 2. This invention utilizes a hook plate, the middle of which is rotatably connected to the outer wall of a guide shaft via a pin. A spring is installed on the outer wall of the hook plate, and the other end of the spring is fixedly connected to the outer wall of the guide shaft. After the target enters the inner cavity of the collection net, the controller is energized to generate a magnetic field. The magnetic force pushes the magnetic plate and pushes the hook plate and connecting ear plate apart through the top pressure rod, thereby releasing the sealing cover until the sealing cover is inserted with the limiting ring, realizing automatic target capture and further improving the efficiency of target collection.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] Example 1: As Figures 1 to 6 As shown in the embodiment of the present invention, an environmental protection monitoring device and monitoring method includes a supporting base plate 1, a container cylinder 2, a collection net 3, a supporting mechanism, a trapping mechanism, and a sealing mechanism. The container cylinder 2 is detachably installed on the upper end face of the supporting base plate 1. The collection net 3 is slidably installed on the inner wall of the container cylinder 2. The collection net 3 is a common stainless steel wire mesh. When capturing a target, the collection net 3 is placed inside the container cylinder 2.

[0041] The bearing mechanism includes a bearing ring 13 and a guide shaft 12. The bearing ring 13 is fixedly installed on the outer wall of the accommodating cylinder 2. The bearing ring 13 and the accommodating cylinder 2 are integrally set. The guide shaft 12 is detachably installed on the upper end face of the bearing ring 13. There are three guide shafts 12, and the axis of the guide shaft 12 coincides with the axis of the bearing ring 13.

[0042] The trapping mechanism includes a protective cover 17 and an information generator 22. The information generator 22 is used to emit trapping information. In this embodiment, the information generator 22 is made of LED beads, which emit light after being powered on, and is used to trap target insects that are attracted to light. The information generator 22 can be detachably installed on the inner wall of the supporting base plate 1. The inner wall of the supporting base plate 1 is provided with a PCB board, and the LED beads are integrated on the PCB board.

[0043] The protective cover 17 is fixedly installed on the upper surface of the supporting base plate 1. The protective cover 17 is located at the upper end of the information generator 22 and is used to close the information generator 22 and protect the lamp beads. The protective cover 17 extends into the interior of the receiving cylinder 2.

[0044] When environmental protection monitoring is required, the information generator 22 sends out a trapping signal, thereby luring the target from the upper end of the container 2 into the inner cavity of the collection net 3.

[0045] The sealing mechanism includes a sealing cover 10 and a sealing cover 21. The sealing cover 21 is detachably installed on the inner wall of the sealing cover 10. Sliding the sealing cover 10 controls the synchronous sliding of the sealing cover 21. The sealing cover 10 is elastically installed on the outer wall of the guide shaft 12. The guide shaft 12 guides the sliding of the sealing cover 10. After the target enters the collection net 3, the elastic force on the sealing cover 10 controls the sliding of the sealing cover 10 until the sealing cover 21 closes the opening end of the collection net 3, thereby capturing the target and facilitating the analysis of biological data and the formulation of effective environmental protection strategies.

[0046] The inner wall of the collecting net 3 is fixedly installed with a limiting ring 5 for the insertion of the closing cover 21. The limiting ring 5 is a common rubber ring. The inner diameter of the limiting ring 5 is equal to the outer diameter of the closing cover 21. After the closing cover 21 is inserted into the limiting ring 5, the closing cover 21 is fixed by friction.

[0047] A sealing plate 23 is detachably installed on the bottom surface of the support base plate 1. The sealing plate 23 is connected to the support base plate 1 by bolts, and a rubber gasket is provided at the contact position between the sealing plate 23 and the support base plate 1 to achieve sealing and waterproof protection of the PCB board and the information generator 22.

[0048] A limiting frame 16 is fixedly installed on the upper end face of the supporting base plate 1. An insertion plate 18 for sliding insertion with the limiting frame 16 is fixedly installed on the inner wall of the accommodating cylinder 2. A groove for insertion of the insertion plate 18 is provided on the side wall of the limiting frame 16. The bottom surface of the accommodating cylinder 2 is pressed against the upper end face of the supporting base plate 1. The accommodating cylinder 2 is rotated until the insertion plate 18 is inserted with the limiting frame 16, so as to realize the detachable connection between the supporting base plate 1 and the accommodating cylinder 2. An absorption layer 15 is provided on the upper end face of the supporting base plate 1. The absorption layer 15 is a common sponge layer, located between the collecting net 3 and the supporting base plate 1, and is used to absorb the feces discharged by the target.

[0049] An mounting plate 19 is fixedly installed on the inner wall of the enclosure 10. The mounting plate 19 and the enclosure 10 adopt an integrated structural design. A rubber nipple 20 for inserting into the mounting plate 19 is fixedly installed on the upper end face of the enclosure 21. A through hole for inserting the rubber nipple 20 is opened on the outer wall of the enclosure 21. The enclosure 21 and the enclosure 10 are detachably connected by inserting the rubber nipple 20 into the through hole.

[0050] The inner wall of the bearing ring 13 is threaded with a connecting cylinder 14. The bottom end of the guide shaft 12 is rotatably connected to the axial end of the connecting cylinder 14. Rotating the connecting cylinder 14 realizes the connection between the guide shaft 12 and the bearing ring 13, so as to provide a trajectory for the sliding of the enclosure 10.

[0051] A connecting lug 11 is fixedly installed on the outer wall of the enclosure 10. A guide shaft 12 passes through the connecting lug 11 and is slidably connected to the connecting lug 11. The inner wall of the connecting lug 11 is slidably fitted to the outer wall of the guide shaft 12. The sliding connection between the enclosure 10 and the guide shaft 12 is achieved by setting the connecting lug 11.

[0052] A connecting spring 4 is fixedly connected to the bottom surface of the connecting ear plate 11. The other end of the connecting spring 4 is fixedly connected to the outer wall of the guide shaft 12. The elastic force of the connecting spring 4 pulls the sealing cover 10 in real time, so that the sealing cover 10 has a downward sliding tendency in real time.

[0053] A hook plate 6 is elastically installed on the outer wall of the guide shaft 12 for engaging with the connecting ear plate 11. The middle part of the hook plate 6 is rotatably connected to the outer wall of the guide shaft 12 via a pin. A spring is provided on the outer wall of the hook plate 6, and the other end of the spring is fixedly connected to the outer wall of the guide shaft 12. The closed cover 10 is slid until the hook plate 6 engages with the connecting ear plate 11, thereby fixing the closed cover 10. The hook plate 6 is moved until it separates from the connecting ear plate 11. At this time, the closed cover 10 is slid by the elastic force of the connecting spring 4 until the closed cover 21 is inserted into the limiting ring 5, thereby achieving target capture.

[0054] A support plate 7 is detachably installed on the outer wall of the guide shaft 12. A limit hook 8 is provided on the upper end face of the support plate 7. The bottom of the limit hook 8 is connected to the support plate 7 by a rope so as to suspend the support plate 7 at the target position.

[0055] A mounting block 9 is fixedly installed on the bottom surface of the support plate 7. A controller 24 is fixedly installed in the inner cavity of the mounting block 9. The controller 24 is a common electromagnet. A magnetic plate 25 is elastically installed on the inner wall of the mounting block 9. A top pressure rod 26 for pushing the hook plate 6 is fixedly installed on the other end of the magnetic plate 25. A spring is fixedly installed on the outer wall of the magnetic plate 25. The other end of the spring is fixedly connected to the inner wall of the mounting block 9. The spring force pushes the magnetic plate 25 in real time, so that the top pressure rod 26 tends to move away from the hook plate 6 in real time.

[0056] When the hook plate 6 needs to be moved, the controller 24 is powered on to generate a magnetic field, which pushes the magnetic plate 25 through the magnetic force and pushes the hook plate 6 to separate from the connecting ear plate 11 through the top pressure rod 26, thereby releasing the sealing cover 10.

[0057] A microcontroller is installed on the inner wall of the mounting block 9. The microcontroller is powered on by the preset time control controller 24 at a preset time, thereby controlling the closing of the collection net 3 according to the trapping time.

[0058] Example 2: Figures 7 to 9 As shown in Example 1, another embodiment of the present invention is as follows:

[0059] A limit frame 32 is provided on the upper end face of the support plate 7. An installation cylinder 28 is fixedly installed on the upper end face of the limit frame 32. The guide shaft 12 passes through the installation cylinder 28, and the inner wall of the installation cylinder 28 slides against the outer wall of the guide shaft 12.

[0060] A limiting ring 30 is slidably installed on the inner wall of the mounting cylinder 28. An elastic plate 27 is fixedly installed on the bottom surface of the limiting ring 30. The elastic plate 27 is a common elastic plastic plate. A conical block 31 is fixedly installed on the other end of the elastic plate 27. Multiple elastic plates 27 and conical blocks 31 are provided and arranged in a ring.

[0061] The inner wall of the conical block 31 fits against the outer wall of the guide shaft 12, and the inclined surface of the conical block 31 slides against the inner wall of the mounting cylinder 28. A conical groove adapted to the conical block 31 is provided on the inner wall of the mounting cylinder 28. After the guide shaft 12 is inserted, the sliding of the mounting cylinder 28 is unidirectionally limited.

[0062] When it is necessary to fix the whole device, insert the guide shaft 12 into the mounting cylinder 28, and then suspend the limit hook 8 at the target position. Under the influence of gravity, the guide shaft 12 slides downward. At this time, the friction between the guide shaft 12 and the outer wall of the conical block 31 pulls the conical block 31 to slide. At this time, the inner wall of the conical groove squeezes the conical block 31 to clamp the guide shaft 12, thereby fixing the support plate 7 and fixing the device.

[0063] After the target enters the inner cavity of the collection net 3, the hook plate 6 is pushed by the top pressure rod 26 to release the sealing cover 10 to seal the collection net 3. Then, the connecting cylinder 14 is rotated until the connecting cylinder 14 is separated from the bearing ring 13. At this time, the sliding adjustment limit ring 30 is adjusted until the conical block 31 is separated from the conical groove. The sliding support plate 7 is adjusted until the mounting cylinder 28 is separated from the guide shaft 12. At this time, the collection net 3 is taken out to realize the capture and collection of the target sample.

[0064] A top pressure spring 29 is fixedly installed on the inner wall of the mounting cylinder 28. The other end of the top pressure spring 29 is fixedly connected to the outer wall of the limiting ring 30. The top pressure spring 29 pushes the limiting ring 30, so that the conical block 31 tends to fit the inner wall of the conical groove in real time.

[0065] The outer wall of the limiting frame 32 slides against the outer wall of the mounting cylinder 28, and the outer wall of the limiting ring 30 is fixedly connected to the inner wall of the limiting frame 32. The sliding limiting frame 32 controls the sliding of the limiting ring 30 so that the conical block 31 can be separated from the conical groove so that the collection net 3 can be taken out.

[0066] like Figure 10 As shown, a monitoring method using an environmental protection monitoring device includes the following steps:

[0067] A1. First, check the power supply of the information generator 22, and then insert the collection net 3 into the inner cavity of the container 2;

[0068] A2. Adjust the support plate 7 and the enclosure 10 to slide into the outer wall of the guide shaft 12, hang the limit hook 8 at the target location, and fix the support plate 7 by the gravity of the whole device and the conical block 31.

[0069] A3. Slide the closed cover 10 until the hook plate 6 engages with the connecting ear plate 11;

[0070] A4. Turn on the information generator 22 to lure the target. After the target enters the collection net 3, push the hook plate 6 and the connecting ear plate 11 through the top pressure rod 26. The closed cover 10 and the closed cover 21 slide down until the closed cover 21 is inserted into the limit ring 5.

[0071] A5. Disassemble the guide shaft 12, separate the closed cover 21 from the mounting plate 19, and finally remove the collection net 3 with the closed cover 21 inserted to complete the target capture and collection.
