Description

Technical Field

[0001] This invention relates to the field of colorimetric measurement technology, specifically to a colorimetric measurement device based on specular reflection with a rapid roll-changing function. Background Technology

[0002] Color-attracting behavior is one of the most important tropism behaviors in insects, playing a crucial role in pest control and the utilization of natural enemies. In agricultural production, some small insects, such as whiteflies, psyllids, and flea beetles, often cause serious damage. By utilizing the color-attracting nature of pests, yellow or other colors can be used to attract pests to the group. Then, by using major imaging equipment to capture more images of the pests, more targeted research can be conducted to prevent different pests, leading to greater progress in agricultural production.

[0003] For most cameras and insect-attracting rolls installed inside the overall device, a large space is required inside the device to position the insect-attracting roll directly opposite the camera. This not only limits the miniaturization of the device, restricting its application in confined or special environments, but also increases the overall size of the device, affecting portability and ease of installation. The winding and positioning of the insect-attracting roll requires a complex mechanical structure, increasing the complexity and failure rate of the device, affecting its reliability and lifespan. The complex mechanical structure also increases manufacturing costs and maintenance difficulty. The complex internal structure of the device, with the insect-attracting roll needing to navigate around multiple axes, and the limited internal space, makes roll-changing inconvenient, requiring users to perform complex operations in a confined space, thus affecting the efficiency of changing the roll.

[0004] To overcome the aforementioned shortcomings, existing technology (Chinese patent publication number: CN220712609U, application date: 2023-09-11) discloses a micro-sized intelligent pest monitoring system. This system includes a frame with a base at the bottom, through which the frame is driven to rotate horizontally; a housing that slides with the frame; a lifting mechanism mounted on the frame; an automatic replacement mechanism located within the housing, comprising two paper rolls and sticky insect-attracting paper connecting the two rolls, the sticky paper at least partially forming a photographing area for a photographing component; a photographing component located within the housing and equipped with a supplementary light; a solar panel located at the top of the frame; an insect-attracting lamp comprising multiple lamps of different wavelengths, all located within the area enclosed by the sticky paper; a perforated plate detachably mounted at the insect inlet to prevent insects larger than the mesh from entering; and a main control board communicatively connected to the automatic replacement mechanism, the photographing component, the lifting mechanism, the solar panel, and the insect-attracting lamp, and equipped with a communication module. This application offers advantages such as extending the lifespan of the sticky paper, automatically adjusting the height, and flexibly targeting specific pests.

[0005] Existing automatic roll-type insect trapping and monitoring equipment has many inconveniences in the operation of changing the insect trap roll. The traditional method of changing the insect trap roll requires opening the equipment and operating inside the equipment to install the roll. The operating space is limited, the operation process is complicated and time-consuming, which affects the working efficiency of the equipment. Moreover, the existing camera setting position greatly affects the observation of insects and is not conducive to the ease of assembly of the overall equipment. It is also susceptible to external interference. Summary of the Invention

[0006] The purpose of this invention is to provide a color-attracting monitoring device based on specular reflection with a rapid roll-changing function, in order to solve the many inconveniences in the existing automatic roll-type insect-attracting monitoring devices mentioned in the background art regarding the replacement of insect-attracting rolls. The traditional method of replacing insect-attracting rolls requires opening the device and operating inside to install the roll. The operating space is limited, the operation process is complex and time-consuming, which affects the working efficiency of the device. Furthermore, the design of the shooting part is not convenient enough. The installation problem between the camera and the insect-attracting roll greatly affects the assembly of the overall device, making the overall device larger and the installation more time-consuming, which greatly increases the trouble in the installation process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a colorimetric monitoring device based on specular reflection with a rapid roll-changing function, comprising a photovoltaic panel mounted on the top of the mounting housing, the photovoltaic panel being fixedly mounted on the top of the mounting housing, a plane mirror mounted below the photovoltaic panel, the plane mirror being rotatably mounted on the front of the mounting housing, an insect-attracting inner groove being provided on the front of the mounting housing, and a sliding transmission mechanism for rotating the sticky insect roll being installed inside the insect-attracting inner groove, the sliding transmission mechanism including a drive motor being fixedly mounted on the right side of the mounting housing, an active shaft being mounted on the output end of the drive motor, the active shaft being rotatably mounted on the right side of the mounting housing, a rotating fixing plate being mounted on the left side of the active shaft, and the other end of the active shaft being rotatably mounted inside the rotating fixing plate;

[0008] The opening and closing contact door is rotatably mounted on the left side of the mounting housing, and an elastic sliding mechanism for fixing the fixed fitting rod is mounted on the back of the mounting housing.

[0009] Furthermore, the elastic sliding mechanism includes a fixed abutment frame, which is fixedly installed on the back of the mounting housing. A fixed fitting rod is installed inside the fixed abutment frame, and the fixed fitting rod is fixedly installed on the outer surface of the opening and closing abutment door. The fixed fitting rod has an L-shaped design, and an inner fitting groove is formed on the upper surface of the end of the fixed fitting rod.

[0010] Furthermore, a sliding rod is installed inside the inner groove of the fitting, and a limiting groove is formed on the outer surface of the sliding rod. An abutment rod is installed inside the limiting groove, and the abutment rod is fixedly installed on the back of the mounting housing. An auxiliary spring is installed on the outer surface of the sliding rod.

[0011] Furthermore, the auxiliary spring is nested on the outer surface of the sliding rod, and a transmission wire assembly is installed on the top of the sliding rod. The lower surface of the transmission wire assembly passes through an auxiliary guide frame, and the auxiliary guide frame is fixedly installed on the back of the mounting housing. A pull rod is installed at the other end of the transmission wire assembly, and a limiting sliding frame is installed on the outer surface of the pull rod. A sliding inner groove is opened on the outer surface of the limiting sliding frame, and the pull rod slides downward along the inside of the sliding inner groove.

[0012] Furthermore, the inner surface of the limiting groove contacts the outer surface of the abutment rod to form a sliding structure, and the end of the auxiliary spring contacts the outer surface of the abutment rod to form an elastic structure. Moreover, the pull rod contacts the top of the fitting sliding rod through the end of the transmission line assembly to form a transmission structure.

[0013] Furthermore, limiting sliding plates are installed on the left and right sides of the rotating fixed plate, and limiting sliding grooves are installed on the outer surface of the limiting sliding plates. The limiting sliding grooves are fixedly installed on the inner surface of the mounting shell, and an insect-sticking plate is installed on the outer surface of the drive shaft.

[0014] Furthermore, a driven shaft is installed above the drive shaft, and the two ends of the driven shaft are rotatably installed inside the mounting housing and the rotating fixing plate, respectively. A guide shaft is installed on the left side of the driven shaft, and the two ends of the guide shaft are rotatably installed inside the mounting housing and the rotating fixing plate, respectively.

[0015] Furthermore, a macro camera is installed on the top of the inner surface of the mounting housing, and the working angle of the macro camera is facing the plane mirror. The sticky insect roll connects the active shaft, the driven shaft, and the guide shaft. When the sticky insect roll is installed on the guide shaft, the outer surface is aligned with the insect-attracting inner groove. An opening and closing contact door is installed on the left side of the mounting housing, and a supporting contact block is installed on the inner surface of the opening and closing contact door.

[0016] Furthermore, the end of the supporting contact block contacts the rotating fixing plate, and the opening and closing contact door is rotatably mounted on the left side of the mounting housing. Moreover, the drive motor and the drive shaft are integrated into one piece, and a control box is installed on the inner bottom surface of the mounting housing.

[0017] Furthermore, the drive shaft, driven shaft, and guide shaft are all rotatably mounted between the right side of the mounting housing and the interior of the rotating fixed plate. The rotating fixed plate and the limiting sliding plate are designed as a single unit, and the inner surface of the limiting sliding groove contacts the outer surface of the limiting sliding plate to form a sliding structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: When the color-attracting detection device based on mirror reflection with a quick roll-changing function needs to replace the sticky insect roll, the drive motor is started, and the drive motor drives the fixedly installed active shaft to rotate. Since the end of the sticky insect roll is fixed to the outside of the active shaft, the sticky insect roll is driven as it rotates. The rotation of the sticky insect roll will simultaneously drive the driven shaft and the guide shaft, which are in sliding contact. The sticky insect roll is extended and replaced through the driven shaft fixed at the other end. The used sticky insect roll is rotated and retracted by the active shaft. Moreover, the reflection design of the plane mirror makes the shooting process of the macro camera more stable and will not cause problems such as unclear shooting images due to weather or external interference. At the same time, it also makes the assembly of the overall device more convenient.

[0019] Furthermore, when it is necessary to replace the sticky insect roll, open the opening and closing contact door and pull the rotating fixed plate backward along the inside of the limit slide groove. This will allow the left end of the drive shaft, driven shaft, and guide shaft to open. In order to ensure the installation stability of the rotating fixed plate, when the opening and closing contact door is closed, the support contact block will push the rotating fixed plate inward to its limit position, ensuring the stability of the installation.

[0020] Furthermore, when it is necessary to open the door, the pull rod is slid down along the inside of the limit sliding frame. The sliding of the pull rod drives the transmission cable assembly to be pulled up along the auxiliary guide frame. The upward sliding of the transmission cable assembly causes the fixed end of the locking sliding rod to be driven upward. The movement of the locking sliding rod is resisted by the abutment rod, which retracts the auxiliary spring until the locking sliding rod leaves the inside of the fixed locking rod, thus completing the opening process of the door.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-9 The present invention provides the following technical solution: a colorimetric measurement device based on specular reflection with a fast roll-changing function, comprising a mounting shell 1, a photovoltaic panel 2, and a contact rod 28.

[0033] A photovoltaic panel 2 is installed on the top of the mounting housing 1 and is fixedly installed on the top of the mounting housing 1. A plane mirror 3 is installed below the photovoltaic panel 2 and is rotatably installed on the front of the mounting housing 1. An insect-attracting inner groove 27 is opened on the front of the mounting housing 1, and a sliding transmission mechanism for rotating the sticky insect roll plate 6 is installed inside the insect-attracting inner groove 27. The sliding transmission structure includes a drive motor 7 and is fixedly installed on the right side of the mounting housing 1. An active shaft 19 is installed at the output end of the drive motor 7 and is rotatably installed on the right side of the mounting housing 1. A rotating fixing plate 23 is installed on the left side of the active shaft 19 and the other end of the active shaft 19 is rotatably installed inside the rotating fixing plate 23.

[0034] The opening and closing contact door 5 is rotatably installed on the left side of the mounting housing 1, and the back of the mounting housing 1 is equipped with an elastic sliding mechanism for fixing the fixed fitting rod 17.

[0035] like Figure 2 , Figure 3 , Figure 4 The technical solution shown, in order to solve the problem of inconvenient manual maintenance in case of malfunction, discloses the following: Limiting sliding plates 25 are installed on the left and right sides of the rotating fixed plate 23, and limiting sliding grooves 24 are installed on the outer surface of the limiting sliding plates 25. The limiting sliding grooves 24 are fixedly installed on the inner surface of the mounting housing 1. An insect-sticking plate 6 is installed on the outer surface of the drive shaft 19. A driven shaft 20 is installed above the drive shaft 19, and both ends of the driven shaft 20 are rotatably installed inside the mounting housing 1 and the rotating fixed plate 23, respectively. A guide shaft 21 is installed on the left side of the driven shaft 20, and both ends of the guide shaft 21 are rotatably installed inside the mounting housing 1 and the rotating fixed plate 23, respectively. A macro camera 18 is installed on the top of the inner surface of the mounting housing 1, and the working angle of the macro camera 18 is directly facing the plane mirror 3. The insect-sticking plate 6 connects the drive shaft 19 and... The driven shaft 20 and the guide shaft 21 are connected to each other. When the sticky insect roll plate 6 is installed on the guide shaft 21, its outer surface is aligned with the insect-attracting inner groove 27. An opening and closing contact door 5 is installed on the left side of the mounting housing 1. A support contact block 26 is installed on the inner surface of the opening and closing contact door 5. The end of the support contact block 26 contacts the rotating fixing plate 23. The opening and closing contact door 5 is rotatably installed on the left side of the mounting housing 1. The drive motor 7 and the drive shaft 19 are integrated. A control box 22 is installed on the inner bottom surface of the mounting housing 1. The drive shaft 19, the driven shaft 20, and the guide shaft 21 are all rotatably installed between the right side of the mounting housing 1 and the inside of the rotating fixing plate 23. The rotating fixing plate 23 and the limiting sliding plate 25 are integrated. The inner surface of the limiting sliding groove 24 contacts the outer surface of the limiting sliding plate 25 to form a sliding structure.

[0036] When it is necessary to recycle and replace the used part of the sticky insect roll plate 6, the drive motor 7, which is fixedly installed on the right side of the mounting housing 1, is started. With the start of the drive motor 7, the drive shaft 19, which is fixedly installed at the output end of the drive motor 7, is driven to rotate. Since the end of the sticky insect roll plate 6 is fixedly installed on the surface of the drive shaft 19, the sticky insect roll plate 6 is driven to rotate as the drive shaft 19 rotates. As the sticky insect roll plate 6 rotates, the guide shaft 21, which is slidably connected to the inner surface of the sticky insect roll plate 6, is also driven to rotate. The installation positions of the two sets of guide shafts 21 correspond to the opening positions of the insect-attracting inner groove 27. The sticky insect roll plate 6 is located outside the two sets of guide shafts 21. The rotation of the drive shaft 19 recycles the used sticky insect roll plate 6. Then, the driven shaft 20, which is fixed at the other end of the sticky insect roll plate 6, is extended outward to replace the unused sticky insect roll plate 6. The plane mirror 3, fixedly installed on the top of the mounting housing 1, is aligned at a 45-degree angle with the outer surface of the sticky insect roll plate 6 and can be adjusted accordingly. The device is rotated and adjusted according to usage. A macro camera 18, fixedly mounted on the top of the inner surface of the housing 1, is used to take pictures of the plane mirror 3. The power supply for the entire housing 1 is provided by a control box 22 fixed inside the housing 1. When replacing the sticky insect roll 6, the opening and closing contact door 5, rotatably mounted on the left side of the housing 1, is opened. Then, the rotating fixing plate 23, slidably mounted inside the housing 1, slides outward along the limit groove 24. Since the left ends of the drive shaft 19, driven shaft 20, and guide shaft 21 are slidably mounted inside the rotating fixing plate 23, removing the rotating fixing plate 23 opens the left ends of the drive shaft 19, driven shaft 20, and guide shaft 21, enabling the replacement operation. Furthermore, to ensure a more stable installation of the rotating fixing plate 23, a support contact block 26 is fixedly mounted on the inner surface of the opening and closing contact door 5. When the opening and closing contact door 5 is closed, the support contact block 26 pushes the rotating fixing plate 23 inward to its limit position, ensuring stable installation.

[0037] like Figure 2 , Figure 3 , Figure 4The technical solution shown, in order to solve the problem of inconvenient manual maintenance in case of malfunction, discloses the following: An elastic sliding mechanism includes a fixed abutment frame 16, which is fixedly installed on the back of the mounting housing 1. A fixed fitting rod 17 is installed inside the fixed abutment frame 16 and is fixedly installed on the outer surface of the opening / closing abutment door 5. The fixed fitting rod 17 has an L-shaped design, and an inner fitting groove 4 is formed on the upper surface of its end. An inner fitting groove 4 is installed inside the inner fitting groove 4, and a sliding rod 13 is installed inside the inner fitting groove 4. A limiting groove 15 is formed on the outer surface of the sliding rod 13, and an abutment rod 28 is installed inside the limiting groove 15. The abutment rod 28 is fixedly installed on the back of the mounting housing 1. An auxiliary spring 14 is installed on the outer surface of the sliding rod 13. Spring 14 is nested on the outer surface of the sliding rod 13, and a transmission wire assembly 11 is installed on the top of the sliding rod 13. The lower surface of the transmission wire assembly 11 passes through the auxiliary guide frame 12, and the auxiliary guide frame 12 is fixedly installed on the back of the mounting housing 1. A pull rod 10 is installed at the other end of the transmission wire assembly 11, and a limiting sliding frame 8 is installed on the outer surface of the pull rod 10. A sliding inner groove 9 is opened on the outer surface of the limiting sliding frame 8, and the pull rod 10 slides downward along the inside of the sliding inner groove 9. The inner surface of the limiting groove 15 contacts the outer surface of the abutment rod 28 to form a sliding structure, and the end of the auxiliary spring 14 contacts the outer surface of the abutment rod 28 to form an elastic structure. The pull rod 10 contacts the top of the sliding rod 13 through the end of the transmission wire assembly 11 to form a transmission structure.

[0038] When the opening and closing operation of the contact door 5 is required, the pull rod 10 slides downward along the inside of the limiting sliding bracket 8 fixedly installed on the back of the mounting housing 1. Since the limiting sliding bracket 8 has a sliding inner groove 9, the pull rod 10 slides downward along the inside of the sliding inner groove 9. The downward movement of the pull rod 10 simultaneously drives the transmission cable assembly 11 fixedly installed on the side of the pull rod 10. Since the transmission cable assembly 11 passes above the auxiliary guide bracket 12 fixedly installed on the back of the mounting housing 1, the transmission cable assembly 11 drives the locking sliding rod 13 fixedly installed at the other end upward. Driven by the transmission cable assembly 11, the locking sliding rod 13 moves upward. During the movement, the abutment rod 28 fixedly installed on the back of the housing 1 slides through the limiting groove 15 opened on the outer surface of the fitting sliding rod 13. As the fitting sliding rod 13 moves upward, the auxiliary spring 14 nested on the outer surface is also driven to move synchronously. During the movement, the auxiliary spring 14 is abutted by the abutment rod 28 and contracts until the lower end of the fitting sliding rod 13 completely leaves the fitting inner groove 4 opened at the corresponding position of the fixed fitting rod 17. The fixed fitting rod 17 is fixedly installed on the outer surface of the opening and closing abutment door 5. After the fixed fitting rod 17 rotates out of the fixed abutment frame 16, the opening and closing abutment door 5 can be rotated to open.
