An insect monitoring instrument

Abstract

The present invention belongs to the technical field of insect extermination, and relates to an insect situation monitoring instrument. The insect situation monitoring instrument comprises a box, an insect baffle, and a filter. Since insects mainly fly toward an insect attracting lamp from one or two directions, one or two insect baffles are hit by more insects and become dirtier and less transparent, which affects the insect attracting effect. At this time, by adjusting the positions of the four insect baffles, the dirtier insect baffles are deviated from the position where the insects mainly fly, so that the original cleaner insect baffles are located at the position where the insects fly. In this way, the frequency of cleaning and replacing the insect baffles can be reduced without reducing the insect attracting effect. When the temperature in the box reaches a certain level, the water in the elastic telescopic tube is vaporized, so that the elastic telescopic tube is extended, and then the brush plate slides toward the end of the filter away from the baffle, and then the filter rotates around the rotating shaft and tilts, and at the same time, the brush brushes the insects on the filter to the edge of the filter and drops them into the insect container below.

Description

Technical Field

[0001] The invention belongs to the technical field of pest control and relates to an insect situation detection and reporting instrument. Background Art

[0002] Insect-killing lamps are a physical control method that uses the phototaxis of pests to lure and kill them. The insects are attracted to the lamps by their phototaxis, wavetaxis, colortaxis, and taxis information, and then killed by electric shock, drowning, poisoning, etc. Insect-killing lamps solve the problems of increasing resistance to pesticides among pests and diseases and the impact of pesticide residues on health.

[0003] The current insecticidal lamp mainly kills insects by electric shock. When the insects hit the electric grid, the electric grid will kill the insects with electric shock, but this method makes the insects stick to the electric grid and difficult to clean. An insect-blocking board can also be set. When the insects hit the insect-blocking board, they fall onto the collection device and then kill the insects. When the insects hit the insect-blocking board, the dust and scales on the insects will stick to the insect-blocking board and reduce the transparency of the insect-blocking board, affecting the insect-attracting effect. The insect-blocking board needs to be replaced or cleaned to meet the insect-attracting effect. In practice, the insects do not come from all directions evenly. The insects often fly in one or two directions, so that the insects often hit the insect-blocking board in one or two directions, making the dirt around the insect-blocking board uneven, but this still affects the insect-attracting effect.

[0004] In order to solve the above problems, the present invention proposes an insect monitoring instrument. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: an insect monitoring instrument, comprising a box 1, an insect blocking plate 11 and a filter 19. The upper end of the box 1 has a through hole 2, a mounting frame is installed at the through hole 2 of the box 1, and an insect trap lamp 7 is installed in the middle of the mounting frame. The insect blocking plate 11 has multiple pieces, and the multiple insect blocking plates 11 enclose a cylindrical body with a circular cross section around the insect trap lamp 7.

[0037] Specifically, the mounting frame includes a first annular plate 3, a second annular plate 10, a first fixed plate 5, and a second fixed plate 8. The first annular plate 3, the second annular plate 10, the first fixed plate 5, and the second fixed plate 8 are coaxially arranged. The first annular plate 3 is fixedly connected to the side wall of the through hole 2 by a first fixed rod 4. In this embodiment, there are four first fixed rods 4, and the four first fixed rods 4 are evenly distributed on the outer circumference of the first annular plate 3. An annular groove is provided at the upper end of the first annular plate 3. The second annular plate 10 is fixedly connected to the first annular plate 3 by a support plate 9, and the second annular plate 10 is located above the first annular plate 3. There are four support plates 9, and the four support plates 9 are evenly fixed on the circumference of the first annular plate 3.

[0038] The first fixing plate 5 is fixedly connected to the first annular plate 3 through the second fixing rod 6, and the first fixing plate 5 is located in the middle of the through hole 2. There are four second fixing rods 6, and the four second fixing rods 6 are evenly distributed along the inner circumference of the first annular plate 3. The insect trap lamp 7 is installed on the first fixing plate 5. The second fixing plate 8 is fixedly arranged on the upper end of the insect trap lamp 7. The second fixing plate 8 has a through hole in the middle. The second fixing plate 8 and the second annular plate 10 are on the same horizontal plane. There is a gap between the second fixing plate 8 and the second annular plate 10. The gap has the function of limiting and guiding the insect blocking plate 11.

[0039] There are multiple insect-blocking plates 11, and the multiple insect-blocking plates 11 are enclosed to form a cylinder with a circular cross-section, and the insect-attracting lamp 7 is located in the cylinder. The upper end of the insect-blocking plate 11 is located in the gap between the second fixing plate 8 and the second annular plate 10, and the lower end of the insect-blocking plate 11 is located in the annular groove. Magnets 12 are installed on both sides of the insect-blocking plate 11, and the magnetic poles of the opposite sides of adjacent magnets 12 are opposite, so that the adjacent insect-blocking plates 11 have the characteristic of repelling each other. A first inclined surface 13 is provided at the two corner ends of the upper end of the insect-blocking plate 11. An iron block 14 is installed in the middle of the upper end of the insect-blocking plate 11. In this embodiment, there are four insect-blocking plates 11. The insect-blocking plate 11 is made of a transparent material.

[0040] The position of the end point of the first inclined surface 13 on the upper end surface of the insect-blocking plate 11 is related to the number of insect-blocking plates 11. In this embodiment, the arc length between the two end points of the upper end surface of the insect-blocking plate 11 should be less than one-third of the arc length of the insect-blocking plate 11. When one of the insect-blocking plates 11 is separated from the other insect-blocking plates 11 and is located above the other insect-blocking plates 11, the other three insect-blocking plates 11 will be separated from each other and evenly distributed under the repulsive force of the magnet 12; that is, there are intervals between the remaining three insect-blocking plates 11, and the sum of the arc lengths of the intervals between the remaining three insect-blocking plates 11 is equal to the arc length of the removed insect-blocking plate 11, that is, the spacing between two adjacent insect-blocking plates 11 is equal to one-third of the arc length of the removed insect-blocking plate 11. Since the arc length between the upper end surfaces of adjacent insect-blocking plates 11 is greater than the arc length of the insect-blocking plate 11, when the separated insect-blocking plate 11 is located directly above the gap between the two adjacent insect-blocking plates 11, if the upper insect-blocking plate 11 moves downward at this time, it will fall between the corresponding two first inclined surfaces 13. Then, the insect blocking plate 11 located above pushes the corresponding insect blocking plate 11 to move away through the first inclined surface 13, so that the removed insect blocking plate 11 is replaced and reinstalled, and the used insect blocking plates 11 form a cylindrical structure again.

[0041] A rain shield 17 is provided on the mounting frame for movement up and down, and the rain shield 17 is rotatably provided on the mounting frame. An electromagnet 18 is fixedly provided at the lower end of the rain shield 17. The electromagnet 18 is provided in the same arc shape as the iron block 14 and is coaxially provided with the iron block 14. The electromagnet 18 cooperates with the iron block 14. When the electromagnet 18 is located directly above one of the iron blocks 14, the electromagnet 18 is energized, and the electromagnet 18 absorbs the corresponding iron block 14, so that the rain shield 17 can be fixedly connected with the corresponding insect-blocking plate 11.

[0042] Specifically, an electric push rod 15 is fixedly mounted on the first fixed plate 5, a motor 16 is fixedly mounted on the top of the push rod of the electric push rod 15, and the output shaft of the motor 16 is fixedly connected to the rain shield 17. The perforation at the upper end of the second fixed plate 8 provides a space for the motor 16 and the electric push rod 15. The electric push rod 15 drives the rain shield 17 to move up and down, and the motor 16 drives the rain shield 17 to rotate.

[0043] The filter screen 19 is rotatably arranged on the inner wall of the housing 1 through a rotating shaft. A torsion spring is sleeved on the rotating shaft, one end of which is fixedly connected to the inner wall of the housing 1, and the other end of which is fixedly connected to the filter screen 19. The torsion spring makes the filter screen 19 in a horizontal state in the initial state. The filter screen 19 has two pieces, and the two filter screens 19 are symmetrically arranged in the housing 1, and the two filter screens 19 are assembled into the same shape as the horizontal cross-section of the housing 1. When the filter screen 19 is in a horizontal state, the ends of the two filter screens 19 away from the rotating shaft are close to each other and have a certain gap. When the filter screen 19 rotates around the corresponding rotating shaft, it will not be interfered by the filter screen 19 on the opposite side.

[0044] Each filter 19 is slidably matched with a brush plate 21, and a slide seat 20 is fixed on both sides of the filter 19. The brush plate 21 is slidably connected with the slide seat 20. The upper end of the brush plate 21 is a second inclined surface, and the lower end of the brush plate 21 is a brush matched with the filter 19. The brush has a certain weight. When the brush slides on the filter 19 toward the middle of the box body 1, the filter 19 will rotate around the rotating shaft, and the insects on the filter 19 will be moved to the edge of the filter 19 and fall off.

[0045] A baffle 23 is fixedly provided at one end of the filter screen 19 close to the box body 1. A mounting groove is provided on the brush plate 21, and an elastic telescopic tube 22 is installed in the mounting groove, one end of the elastic telescopic tube 22 is fixedly connected to the bottom wall of the mounting groove, and the other end of the elastic telescopic tube 22 is fixedly connected to the baffle 23. The elastic telescopic tube 22 is filled with a temperature control liquid, and the temperature control liquid in this embodiment is water.

[0046] In the natural state, the elastic telescopic tube 22 is in a telescopic state, and the brush plate 21 is located at one end of the filter 19 close to the baffle 23. At this time, the filter 19 is in a horizontal state under the action of the torsion spring. When the temperature in the box 1 rises to a certain level, the water in the elastic telescopic tube 22 will quickly vaporize, increasing the volume of the water vapor, causing the elastic telescopic tube 22 to overcome its own elastic force and stretch. The elastic telescopic tube 22 drives the brush plate 21 to slide away from the baffle 23. Due to the principle of the lever, the end of the filter 19 away from the rotating shaft rotates downward around the rotating shaft under the action of the brush plate 21, causing the filter 19 to tilt. The brush brushes the insects on the filter 19 to the edge of the filter 19 and falls downward under the action of gravity.

[0047] A heater 26 and a camera 27 are installed in the box 1. The heater 26 raises the temperature in the box 1, and when the temperature reaches a certain level, the insects in the box 1 are killed. Raising the temperature in the box 1 to 100 degrees Celsius can vaporize the water in the elastic telescopic tube 22. The camera 27 takes pictures of the insects on the filter 19 at a preset time and uploads the pictures to the cloud platform. After AI analysis, the types and quantities of the insects are automatically identified, and the identification results are pushed to relevant units. Provide insect information to staff.

[0048] A collection box 24 is fixedly arranged at the bottom of the filter 19, and the collection box 24 is connected to a connecting pipe 25, and one end of the connecting pipe 25 away from the filter 19 passes through the side wall of the box 1 and extends to the outside of the box 1. When it rains, rainwater enters the box 1 through the through hole 2, falls into the collection box 24 through the filter 19, and is discharged to the outside of the box 1 through the connecting pipe 25.

[0049] An insect container 28 for collecting insects is arranged at the bottom of the box body 1 , and the box body 1 has a closing door 29 to facilitate cleaning of the insects in the insect container 28 .

[0050] The insect situation detector also includes a rain sensor, a light sensor, and a controller. The rain sensor, the light sensor, the heater 26, the insect trap light 7, the camera 27, the electric push rod 15, and the motor 16 are all electrically connected to the controller. Through the rain sensor, when it rains and the number of insects is small, the insect situation detector automatically enters the standby state. Through the light sensor, when there are more insects at night, the insect situation detector automatically turns on, and when the light is strong during the day, the insect situation detector automatically turns off.

[0051] Working principle: In the initial state, the elastic telescopic tube 22 is in a shortened state, the brush plate 21 is located at one end of the filter screen 19 close to the baffle 23, and the filter screen 19 is in a horizontal state under the action of the torsion spring.

[0052] When in use, turn on the insect trap lamp 7, and the insects fly towards the insect trap lamp 7 under the lure of the insect trap lamp 7. In the process of flying towards the insect trap lamp 7, the insects hit the insect blocking plate 11. After hitting the insect blocking plate 11, the insects will fall and fall onto the filter 19 through the through hole 2. In this way, the insects continue to fall onto the filter 19. After a period of time, there are more and more insects on the filter 19. When the number of insects on the filter 19 reaches a certain amount, the heater 26 is started to raise the temperature in the box 1 to 85 degrees Celsius. The insects are killed without damage under high temperature baking at 85°C. Then the camera 27 takes pictures of the insects at the preset time and uploads the pictures to the cloud platform. After AI analysis, the type and number of insects are automatically identified, and the identification results can be pushed to relevant units. Then, by controlling the heater 26, the temperature in the box 1 is raised to 100°C. At this time, the water in the elastic telescopic tube 22 is violently vaporized, and the volume of the gas in the elastic telescopic tube 22 increases rapidly, so that the elastic telescopic tube 22 overcomes its own elastic potential energy and stretches. The elastic telescopic tube 22 pushes the brush plate 21 to move toward the middle of the box body 1. The brush plate 21 is gradually moved away from the rotating shaft between the filter screen 19 and the box body 1, and the force arm between the brush plate 21 and the rotating shaft is gradually increased, thereby gradually increasing the torque of the brush plate 21 acting on the rotating shaft. When the torque increases to a certain extent, the brush plate 21 causes the filter screen 19 to overcome the elastic force of the torsion spring and rotate downward around the rotating shaft, so that the filter screen 19 becomes tilted. When the filter screen 19 tilts, the elastic force of the torsion spring will increase. Then, as the brush plate 21 moves, the torque of the brush plate 21 on the rotating shaft is further increased, so that the filter screen 19 continues to overcome the elastic force of the torsion spring and rotates downward around the corresponding rotating shaft. Until the brush plate 21 moves to the edge of the filter screen 19 away from the rotating shaft. When the torque of the brush plate 21 on the rotating shaft is balanced with the elastic potential energy of the torsion spring, the filter screen 19 stops rotating.

[0053] The insects on the filter 19 move toward the edge of the filter 19 under the action of the brush plate 21, and then fall from the edge of the filter 19 under the action of gravity and fall into the insect container 28. Then turn off the heater 26, the temperature in the box 1 will gradually decrease, and the water vapor in the elastic telescopic tube 22 will gradually liquefy and the volume will decrease. The elastic telescopic tube 22 gradually shortens and returns to the initial state under the action of its own elasticity, and the elastic telescopic tube 22 drives the brush plate 21 to move in the direction close to the baffle 23, and the brush plate 21 gradually returns to the initial position. When the brush plate 21 gradually moves in the direction close to the baffle 23, the torque of the brush plate 21 and the corresponding rotating shaft gradually decreases, so that the filter 19 gradually rotates around the rotating shaft to a horizontal state, and finally returns to a horizontal state.

[0054] Because the insect condition detector is equipped with a light sensor and a rain sensor, when it is rainy and the number of insects is small, the insect condition detector automatically stops working and enters a standby state. When rainwater enters the box body 1 through the through hole 2 on a rainy day, the rainwater will enter the collection box 24 through the filter 19 and then be discharged to the outside of the insect condition detector through the connecting pipe 25.

[0055] When insects hit the insect shield 11, dust or scales on the insects will adhere to the surface of the insect shield 11, affecting the light transmittance of the insect shield 11, and further affecting the insect attracting effect of the insect attracting lamp 7. In actual use, insects often fly from one or two directions, so insects often hit one or two insect shields 11, so that one or two of the four insect shields 11 will be dirtier than the other insect shields 11.

[0056] For the convenience of description, the four insect-blocking plates 11 are respectively named as No. 1 insect-blocking plate 1101, No. 2 insect-blocking plate 1102, No. 3 insect-blocking plate 1103, and No. 4 insect-blocking plate 1104. Assume that most bookworms hit No. 1 insect-blocking plate 1101 and No. 2 insect-blocking plate 1102, and No. 1 insect-blocking plate 1101 and No. 2 insect-blocking plate 1102 are adjacent, so that No. 1 insect-blocking plate 1101 and No. 2 insect-blocking plate 1102 are dirtier than No. 3 insect-blocking plate 1103 and No. 4 insect-blocking plate 1104. At this time, by adjusting the positions between No. 1 insect-blocking plate 1101 and No. 2 insect-blocking plate 1102 and No. 3 insect-blocking plate 1103 and No. 4 insect-blocking plate 1104, the insect situation detector can be used normally.

[0057] Start the motor 16, which drives the rain shield 17 to rotate, so that the electromagnet 18 on the rain shield 17 moves to the top of the No. 3 insect shield 1103 and corresponds to the iron block 14 on the No. 3 insect shield 1103. Then turn off the motor 16, start the electromagnet 18, so that the electromagnet 18 adsorbs the iron block 14, and then the No. 3 insect shield 1103 is fixedly connected to the rain shield 17. Then start the electric push rod 15, so that the electric push rod 15 extends, and the electric push rod 15 will drive the rain shield 17 and the No. 3 insect shield 1103 to move upward until the No. 3 insect shield 1103 is separated from the other insect shields 11, and the No. 3 insect shield 1103 passes the gap between the second fixing plate 8 and the second annular plate 10 and is above the other insect shields 11. Stop the electric push rod 15. At this time, the first insect deflector plate 1101, the second insect deflector plate 1102, and the fourth insect deflector plate 1104 will rotate along the annular groove under the repulsive force of the magnet 12, so that the adjacent insect deflector plates 11 are away from each other and the three insect deflector plates 11 reach a balanced state. At this time, the distance between two adjacent insect deflector plates 11 among the three insect deflector plates 11 is equal to one third of the arc length of the insect deflector plate 11.

[0058] The motor 16 is started, and the motor 16 drives the rain shield 17 and the third insect shield 1103 to rotate. When the third insect shield 1103 moves to the top of the gap between the first insect shield 1101 and the second insect shield 1102, the motor 16 is turned off, and the electric push rod 15 is started to shorten the electric push rod 15, and the electric push rod 15 drives the rain shield 17 and the third insect shield 1103 to move downward. The lower end of the third insect shield 1103 passes through the gap between the second fixing plate 8 and the second annular plate 10 and gradually approaches the upper ends of the first insect shield 1101 and the second insect shield 1102. When the lower end of the third insect-blocking plate 1103 contacts the first inclined surface 13 between the first insect-blocking plate 1101 and the second insect-blocking plate 1102, the third insect-blocking plate 1103 pushes the first insect-blocking plate 1101 and the second insect-blocking plate 1102 to move away from each other through the first inclined surface 13, and the third insect-blocking plate 1103 enters between the first insect-blocking plate 1101 and the second insect-blocking plate 1102 until the lower end of the third insect-blocking plate 1103 enters the annular groove on the first annular plate 3. The electric push rod 15 is turned off, and the electromagnet 18 is turned off. The gap between the second fixed plate 8 and the second annular plate 10 has a limiting and guiding effect on the third insect-blocking plate 1103, so that the third insect-blocking plate 1103 can smoothly push the first insect-blocking plate 1101 and the second insect-blocking plate 1102 to move.

[0059] Then, the fourth insect-blocking plate 1104 is placed between the third insect-blocking plate 1103 and the first insect-blocking plate 1101 or the second insect-blocking plate 1102 in the above manner. In this way, the positions of the four insect-blocking plates 11 are adjusted, that is, the positions of the third insect-blocking plate 1103 and the fourth insect-blocking plate 1104 are exchanged with the positions of the first insect-blocking plate 1101 and the second insect-blocking plate 1102, so that the insects will hit the third insect-blocking plate 1103 or the fourth insect-blocking plate 1104. The frequency of replacing and cleaning the insect-blocking plate 11 is reduced.

[0060] Of course, the position of the four insect blocking plates 11 can also be adjusted by moving the first insect blocking plate 1101 and the second insect blocking plate 1102 .

[0061] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
