[0002] In the field of schistosomiasis control, Oncomelania snails, as the only intermediate host of Schistosoma, directly influence the risk of disease transmission due to their breeding and spread. These mollusks inhabit humid environments in schistosomiasis-endemic areas year-round, including moist field ridges, silted ditches, slow-flowing rivers, densely vegetated riverbanks, and lakes with abundant aquatic plants. Systematic surveys of Oncomelania snail distribution and population density monitoring are not only fundamental to developing precise control strategies but also crucial for evaluating the effectiveness of snail eradication measures.

[0003] Traditional snail surveys rely heavily on experience for manually delineating survey areas, leading to problems such as unclear boundaries and low efficiency, especially in complex terrain where it's difficult to guarantee survey coverage. Regarding tools, while the standard 33.33cm square wire mesh frame is widely used, its structural stability is insufficient, making it susceptible to displacement or shaking in wet and muddy environments, directly affecting sampling accuracy. More importantly, existing tools lack visual aids, making it difficult for surveyors to quickly establish spatial references, resulting in time-consuming and error-prone area delineation. Although existing technologies... Figure 7 As shown, there is a laser screw-checking frame, but this type of laser screw-checking frame is easily tilted by external forces, causing the screw-checking area to shift, affecting the accuracy of the screw-checking and resulting in inaccurate screw-checking.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] A laser screw-in mounting frame, comprising as follows Figures 1-6 As shown in this embodiment of the utility model, a laser screw-checking frame includes a housing 10, a mounting groove 11 on the side of the housing 10, a control panel 12 on the upper surface of the housing 10, a rotating shaft 20 rotatably mounted at both ends inside the mounting groove 11, a hinge plate 21 fixedly connected to the rotating shaft 20, and a projection component for projecting onto a designated area inside the hinge plate 21; a rotating groove 22 is provided inside the housing 10 below the rotating shaft 20, a gear 23 is rotatably mounted inside the rotating groove 22, and a fixing component for fixing the device to the ground is provided on the side of the gear 23; a limiting component for locking the rotating shaft 20 is provided on the side of the opening of the mounting groove 11 at the upper end of the housing 10.

[0025] In this embodiment, the design of the outer shell 10, mounting groove 11, and control panel 12, along with the combination of the rotating shaft 20 and the opening / closing plate 21 within the mounting groove 11, allows the equipment to be flexibly opened or closed. The projection component built into the opening / closing plate 21 can project onto a designated area, providing users with intuitive visual assistance to limit the screw-checking area and improve work efficiency. The gear 23 below the rotating shaft 20, in conjunction with the fixing component, enhances the stability of the equipment on the ground, ensuring stable operation even in complex environments. At the same time, the limiting component at the upper end of the outer shell 10 effectively locks the rotating shaft 20, effectively fixing the opened opening / closing plate 21 to prevent it from moving due to collisions or other external forces, ensuring operational stability and screw-checking accuracy, and improving the safety and reliability of the equipment.

[0026] Specifically, the fixing components include gear 25, swivel ring 26, and fixing post 28. Gear 1 23 has a rotating groove 24 inside the outer casing 10 on its side. Gear 25 is rotatably installed inside the rotating groove 24. Shaft 1 20 is fixedly connected to gear 25. Gear 25 has a moving groove 27 inside the outer casing 10 in the middle. Fixing post 28 is movably arranged inside the moving groove 27. Helical groove 29 is formed around the fixing post 28. Gear 2 25 has a meshing block that meshes with the helical groove 29 inside.

[0027] In this embodiment, the fixing assembly of the screw-checking frame, through the cooperation of components such as gear 23, gear 25, rotating ring 26, and fixing post 28, achieves the stable fixing function of the equipment in the ground environment, providing reliable support for screw-checking operations. When the user operates the screw-checking frame to unfold the opening and closing plate 21 for work, the fixing assembly is triggered simultaneously. Specifically, as the rotating shaft 20 rotates, it drives the gear 25 fixedly connected to it to start rotating. As a power transmission component, the gear 25 has a meshing block designed inside that meshes with the spiral groove 29 on the periphery of the fixing post 28. Driven by the rotation of gear 25, the fixing post 28 begins to move up and down along the trajectory of the moving groove 27. When it is necessary to fix the equipment, the rotation direction of gear 25 causes the fixing post 28 to move downwards. The pointed end of the fixing post 28, gradually inserted into the ground, effectively enhances the contact force with the ground, ensuring that the screw-checking frame is firmly fixed to the ground and preventing displacement or shaking of the equipment due to external forces during operation. Conversely, when it is necessary to release the equipment or adjust its position, simply change the rotation direction of gear 25, and the fixing post 28 will move upward along the moving groove 27, gradually detaching from the ground, realizing easy release and movement of the equipment. This design achieves convenient operation for fixing and releasing the equipment, improves the adaptability of the equipment in the ground environment, and can quickly and firmly fix it to the ground, providing a stable and reliable platform for subsequent screw-checking work. At the same time, this design also simplifies the operation process, reduces the difficulty of operation for users, improves work efficiency, and makes screw-checking operations more efficient and accurate.

[0028] Specifically, the limiting components include a second rotating shaft 31, a connecting rod 32, and an insertion post 33. A slot 30 is opened on the side of the opening of the mounting groove 11 at the upper end of the outer shell 10. The second rotating shaft 31 is rotatably installed inside the slot 30. The second rotating shaft 31 is movably connected to the connecting rod 32. An insertion post 33 is fixedly installed below one end of the connecting rod 32. An insertion groove 34 is opened on the upper surface of the first rotating shaft 20.

[0029] In this embodiment, the locking assembly of the screw-locking frame, through the combination of components such as the second rotating shaft 31, the connecting rod 32, and the insertion post 33, constructs a simple and efficient locking mechanism for the first rotating shaft 20. During the use of the screw-locking frame, when the opening and closing plate 21 is unfolded to a suitable working angle and it is necessary to lock the first rotating shaft 20 to prevent accidental rotation, the user only needs to manually rotate the connecting rod 32. This operation, using the second rotating shaft 31 as a fulcrum, smoothly and accurately transmits the force to the insertion post 33. The second rotating shaft 31 rotates stably at one end inside the slot 30, providing reliable support for the swing of the connecting rod 32 and ensuring the smoothness of the entire locking process. As the connecting rod 32 rotates, its end... The fixed insertion post 33 begins to move along the preset trajectory. When the connecting rod 32 rotates to a specific position, the insertion post 33 is precisely aligned with the insertion slot 34 on the upper surface of the rotating shaft 20 and is smoothly inserted into it. The tight fit between the insertion post 33 and the insertion slot 34 effectively prevents the rotation of the rotating shaft 20. Since the rotating shaft 20 is directly connected to the opening and closing plate 21, locking the rotating shaft 20 also directly locks the opening and closing plate 21, ensuring the stability of the opening and closing plate 21 during operation. The design is simple and practical, and has extremely high reliability. It can effectively prevent the screw frame from moving unexpectedly due to collision or other external forces, thereby avoiding the risk of equipment damage or operational errors.

[0030] Specifically, the projection assembly includes a movable plate 35, a laser emitter 36, and a slider 37. A groove is provided at one end of the rotating shaft 20, and the movable plate 35 is movably arranged inside the groove. The laser emitter 36 is provided on the side of one end of the movable plate 35, and the slider 37 is fixedly arranged on both sides of the movable plate 35. A sliding groove is provided on the inner side of the groove inside the rotating shaft 20, and the slider 37 is slidably arranged inside the sliding groove.

[0031] In this embodiment, the projection component of the screw-checking frame, through the coordinated operation of components such as the moving plate 35, laser emitter 36, and slider 37, achieves the function of projecting onto a designated area, providing clear and intuitive visual assistance for screw-checking work, and improving the practicality and ease of operation of the equipment. When the screw-checking frame is ready and projection positioning is required, the projection component starts working. The user can manually push the built-in drive mechanism to control the moving plate 35 to slide in the groove inside the rotating shaft 20 according to the actual work needs. The sliders 37, which are fixedly set on both sides of the moving plate 35, cooperate with the sliding grooves opened on the side of the groove inside the rotating shaft 20. The sliders 37 slide smoothly in the sliding grooves, ensuring the stability of the moving plate 35 during the sliding process, avoiding shaking or displacement, thereby ensuring the accuracy of the projection position. When the moving plate 35 slides to the appropriate position, the laser emitter... The laser emitter 36 is activated and emits a laser beam. Since both sides of the screw-checking frame are equipped with such laser emitters 36, the laser emitters 36 on both sides work simultaneously. The laser beams emitted by them cooperate to form a clear and well-defined area boundary. This area can be flexibly adjusted according to actual needs. By changing the position of the moving plate 35, the projection area can be expanded or reduced to adapt to screw-checking areas of different sizes and shapes. In practical applications, it provides users with an intuitive visual reference. Users do not need complicated measurements and markings. They only need to observe the projection area to quickly and accurately determine the screw-checking range, which greatly improves work efficiency. At the same time, the high visibility of the laser beam allows the projection area to be clearly identified under various lighting conditions. Whether in a bright outdoor environment or a dimly lit indoor place, it can ensure the smooth progress of screw-checking work.

[0032] Specifically, a groove is provided on the upper part of the gear 25 inside the outer casing 10, and a rotating ring 26 is rotatably arranged inside the groove, and the rotating ring 26 is fixedly connected to the surface of the gear 25.

[0033] In this embodiment, the rotating ring 26 is rotatably disposed in the groove above the gear 25 and is fixedly connected to the surface of the gear 25. This allows the gear 25 to be restricted when rotating by the rotating ring 26. The presence of the rotating ring 26 not only enhances the structural stability of the gear 25, but also provides the necessary support and guidance for the vertical movement of the fixing column 28, ensuring the normal operation of the fixing assembly.

[0034] Specifically, a limiting groove 210 is provided at the upper end of the fixed column 28, and a limiting plate 211 is movably arranged inside the limiting groove 210. The limiting plate 211 is fixedly arranged inside the upper end of the movable groove 27.

[0035] In this embodiment, a limiting plate 211 is fixedly installed inside the upper end of the moving groove 27, while a limiting groove 210 is opened on the upper end of the fixing column 28. When the fixing column 28 moves up and down in the moving groove 27, the limiting plate 211 slides in the limiting groove 210, which effectively prevents the fixing column 28 from moving excessively or coming out, and ensures the safety and reliability of the fixing component.

[0036] Specifically, scales 38 are provided on both sides of the movable plate 35.

[0037] In this embodiment, the scales 38 on both sides of the movable plate 35 provide users with accurate measurement basis. When using the projection component for positioning or measurement, users can accurately determine the position or moving distance of the movable plate 35 by observing the scales 38, thereby accurately determining the projection area and enhancing the practicality of the device.

[0038] The user places the screw frame stably on the surface area to be tested. The user issues a command via the control panel 12, which drives the rotating shafts 20 at both ends of the mounting slot 11 to rotate. The rotation of the rotating shafts 20 causes the opening and closing plate 21, which is fixedly connected to them, to gradually unfold until the preset working angle is reached. After confirming the projection range, the user manually pulls the moving plate 35 out a set distance. At this point, the projection component inside the opening and closing plate 21 is initialized and ready for projection operation. Simultaneously with the rotation of the rotating shafts 20, since the rotating shafts 20 are fixedly connected to the gear 25, the gear 25 rotates synchronously within the rotating slot 24. The meshing block inside the gear 25 engages with the outer periphery of the fixing post 28. The spiral groove 29 begins to mesh. As the gear 25 continues to rotate, the meshing action drives the fixed column 28 to move downward along a predetermined trajectory within the moving groove 27. The limiting groove 210 at the upper end of the fixed column 28 cooperates with the limiting plate 211 fixedly installed at the upper end of the moving groove 27 to prevent the fixed column 28 from moving excessively or coming off, ensuring stability during the movement process. Finally, the bottom end of the fixed column 28 makes close contact with the ground surface. Through the pointed tip at its bottom, the screw-checking frame is firmly fixed to the ground surface, preventing the equipment from shifting or shaking due to external forces during operation. This provides a stable platform for screw-checking work, ensuring that the projection component can accurately project in the designated area, and assisting users in efficiently completing screw-checking tasks.

[0039] The control panel 12 can automatically record the screw-check trajectory, points, location information, screw-check information, etc. through the projection area and automatically upload them to the server, which can be directly accessed on the computer. At the same time, the screw-check trajectory and frame information of the environment are automatically merged and organized, or manually adjusted and automatically generated screw-check logs and frame tables.

[0040] Specifically, the control panel 12 is equipped with a GPS positioning module and an information input module. The information input module, such as a mobile phone, can input monitoring information from various points and send it to the server.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
