[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides the following technical solution: A transmission device for monitoring the water environment based on fiber optic sensing technology, comprising a support platform 1, a controller 2 mounted on top of the support platform 1, an optical fiber cable 3 connected to the input end of the controller 2, an optical fiber sensor 4 connected to the input end of the optical fiber cable 3, a gravity hammer 5 mounted on the outer side of the lower end of the optical fiber cable 3, and floats 20 connected to both the front and rear sides of the support platform 1; a servo motor 6 mounted on the front left side of the support platform 1, and a bidirectional lead screw 7 connected to the output end of the servo motor 6. The outer side of the screw 7 is connected to a movable seat 8 by a threaded connection. The outer side of the double-acting screw 7 is connected to a first bevel tooth 9 by a key. The front side of the first bevel tooth 9 is engaged with a second bevel tooth 10. The middle part of the second bevel tooth 10 is connected to a rotating shaft 11 by a key. The end of the rotating shaft 11 is rotatably connected to the support platform 1. A limit seat 21 is installed on the upper side of the support platform 1. The inside of the support platform 1 is rotatably connected to an adjusting screw 12. The outer side of the adjusting screw 12 is connected to a movable plate 13 by a threaded connection. The lower end of the movable plate 13 is hinged to an adjusting rod 14. The lower end of the adjusting rod 14 is hinged to a gravity hammer 5.

[0027] Furthermore, the optical fiber cable 3 passes sequentially through two sets of limiting seats 21 and two sets of moving seats 8. The moving seats 8 penetrate the upper wall of the support platform 1 and are slidably connected to the support platform 1, which can limit and guide the optical fiber cable 3. The length of the optical fiber cable 3 underwater can be adjusted by moving the moving seats 8. The front and rear sections of the bidirectional lead screw 7 have opposite thread distribution directions. The opposite thread distribution sections of the bidirectional lead screw 7 are connected to the moving seats 8. The rotation of the bidirectional lead screw 7 can drive the moving seats 8 to move in the opposite direction at the same time. The rotating shaft 11 and the adjusting lead screw 12 are distributed parallel to each other. The rotating shaft 11 and the adjusting lead screw 12 are driven by belt. The rotation of the rotating shaft 11 can drive the adjusting lead screw 12 to rotate synchronously, realizing the transmission between the two. The moving plate 13 has a "T" shaped structure. The moving plate 13 penetrates the lower wall of the support platform 1 and is slidably connected to the support platform 1, which can prevent the moving plate 13 from detaching from the support platform 1, so that the moving plate 13 can move horizontally to adjust the position of the optical fiber sensor 4 underwater.

[0028] Specifically, the support platform 1 is placed on the water surface. The buoyancy of the float 20 keeps the support platform 1 afloat. The fiber optic sensor 4 extends underwater, using optical fiber as the sensing medium. It detects environmental changes by monitoring changes in the propagation characteristics of light within the fiber. In the aquatic environment, the fiber optic sensor 4 can detect various pollutants such as chemicals, heavy metals, biotoxins, and radioactive substances, and transmits the monitoring data to the controller 2. The controller 2 analyzes and processes the data, connects the servo motor 6 to the power supply, and controls the bidirectional lead screw 7 connected to the output end to rotate. The bidirectional lead screw 7 controls the rotation of the first bevel tooth 9 connected to the outer key, which in turn controls the rotation of the meshing second bevel tooth 10. The second bevel tooth 10 then controls... The inner key-connected shaft 11 rotates, which controls the belt-connected adjusting screw 12 to rotate. The adjusting screw 12 controls the outer threaded moving plate 13 to move to the left. The moving plate 13 controls the lower hinged adjusting rod 14 to rotate, which controls the lower hinged gravity hammer 5 to move down, thereby driving the fiber optic cable 3 and fiber optic sensor 4 to move down. At the same time, the bidirectional screw 7 rotates, which can control the relative movement of the outer threaded moving seat 8, thereby relaxing the tension on the fiber optic cable 3. This allows the fiber optic cable 3 to adapt to the moving distance of the fiber optic sensor 4 for expansion and contraction, while maintaining the tension of the fiber optic cable 3. The fiber optic sensor 4 is then moved down to different height positions in the water environment for monitoring.

[0029] The fiber optic sensor 4 is equipped with a protective component to prevent external impurities from affecting the monitoring effect.

[0030] Furthermore, the protective assembly includes a fixed cover 15 installed at the lower end of the fiber optic cable 3, an adjusting cover 16 is bolted to the lower side of the fixed cover 15, a rotating rod 17 is rotatably connected to the lower end of the adjusting cover 16, a fan blade 18 is installed on the outside of the rotating rod 17, and a scraper 19 is connected to the outside of the rotating rod 17.

[0031] Furthermore, both the fixed cover 15 and the adjusting cover 16 have a mesh structure, and scrapers 19 are attached to the outside of both the fixed cover 15 and the adjusting cover 16, which can intercept impurities and clean the attached impurities through the scrapers 19.

[0032] Specifically, water in the aquatic environment comes into contact with the fiber optic sensor 4 through the mesh-like fixed cover 15 and adjusting cover 16, preventing impurities in the water from adhering to the fiber optic sensor 4. At the same time, the flow of water will drive the fan blade 18 to rotate, and the fan blade 18 controls the rotating rod 17 to rotate on the adjusting cover 16, thereby controlling the rotating rod 17 to drive the scraper 19 to rotate, scraping and cleaning the fixed cover 15 and adjusting cover 16, preventing impurities from adhering and affecting the monitoring effect of the fiber optic sensor 4. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
