DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] In order to facilitate the detection of water bodies at different depths, as an embodiment of the present invention, Figure 1-3 As shown, a detection device for water environment in water areas described in the present invention comprises a vertically arranged fixed rod 1, the upper end of the fixed rod 1 is fixedly connected to a mounting frame 2, an electric wire winder is fixedly connected inside the mounting frame 2, a steel cable 3 is wound around the electric wire winder, the upper end of the fixed rod 1 is slidably connected to a moving structure, the lower end of the steel cable 3 is fixedly connected to the moving structure, one side of the moving structure is fixedly connected to a detection structure, a cleaning structure is provided on the outer side of the detection structure, a driving structure is provided at the lower end of the moving structure, and the driving structure drives the cleaning structure to work during the up and down movement.

[0018] When in use, when it is necessary to detect the water body, the lower end of the fixed rod 1 is vertically inserted into the water body. At this time, the detection structure is located above the water surface. When it is necessary to detect different depths of the water body, the electric winder is used to release the steel cable 3. At this time, the mobile structure moves downward and drives the detection structure to move downward synchronously. After the detection structure moves downward, water bodies of different depths can be detected, thereby improving the convenience of water quality detection. When the mobile structure moves downward, the driving structure drives the cleaning structure to work, and the cleaning structure cleans the outside of the detection structure to prevent impurities in the water from accumulating on the outside of the detection structure during the downward movement of the detection structure, causing blockage of the outside of the detection structure, and preventing the water from entering the detection structure, thereby affecting the detection effect of the water body; It should be pointed out that the fixing rod 1 described in the present invention can be spliced ​​by several groups of rods, and adjacent rods can be connected by threads, so as to facilitate the splicing of fixing rods 1 of appropriate length according to actual use requirements, and after the splicing is completed, it should be ensured that the first spiral guide groove 17 and the guide groove 5 can be used normally.

[0019] In order to facilitate the downward movement of the detection structure, for example, Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes that the movable structure includes a counterweight ring 4 mounted on the fixed rod 1, the lower end of the steel cable 3 is fixedly connected to the upper surface of the counterweight ring 4, the inner side of the counterweight ring 4 is fixedly connected with a plurality of groups of vertically arranged longitudinal guide sliders 30, the fixed rod 1 is provided with a vertically arranged guide slot 5, and the longitudinal guide slider 30 is slidably connected to the guide slot 5.

[0020] During use, when it is necessary to detect different depths of water bodies, the steel cable 3 is released by the electric winder, and the counterweight ring 4 is moved downward by relying on its own weight. When the counterweight ring 4 moves downward, it relies on the longitudinal guide slider 30 to slide in the guide slot 5 to ensure the downward stability of the counterweight ring 4 and to facilitate the counterweight ring 4 to drive the detection structure to move downward synchronously, thereby facilitating the detection of water bodies at different depths; it should be pointed out that the specifications of the longitudinal guide slider 30 should be large to avoid the longitudinal guide slider 30 being stuck in the first spiral guide slot 17.

[0021] For example, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the detection structure includes a vertically arranged detection cylinder 6, the outer side of the detection cylinder 6 is fixedly connected with a connecting rod 7, the detection cylinder 6 is fixedly connected to one side of the counterweight ring 4 through the connecting rod 7, the lower end of the detection cylinder 6 is fixedly connected with a protective shell 8 with an opening facing upward, a plurality of groups of detection probes 9 are arranged inside the detection cylinder 6, the lower ends of the detection probes 9 pass through the detection cylinder 6 and are located in the protective shell 8, the outer side of the protective shell 8 is provided with a plurality of groups of water inlet holes 10 arranged through, the outer side of the detection cylinder 6 is rotatably connected with a horizontally arranged first rotating ring 11, the lower surface of the first rotating ring 11 is fixedly connected with a vertically arranged arc-shaped cleaning plate 12, the arc-shaped cleaning plate 12 is in contact with the outer side of the protective shell 8, the outer side of the first rotating ring 11 is provided with a circumferentially distributed first tooth structure 13, and the driving structure is meshed with the first tooth structure 13 for transmission.

[0022] During use, when the counterweight ring 4 moves downward, the connecting rod 7 drives the detection tube 6 and the protective shell 8 to move downward synchronously. After the protective shell 8 moves down into the water body, the water enters the protective shell 8 through the water inlet hole 10. At the same time, the water quality is detected by the detection probe 9. As the counterweight ring 4 drives the detection tube 6 to move downward, the driving structure engages with the first tooth structure 13 for transmission, and drives the first rotating ring 11 to rotate. When the first rotating ring 11 rotates, it drives the arc cleaning plate 12 to rotate. The water inlet hole 10 on the outside of the protective shell 8 is cleaned by the rotation of the arc cleaning plate 12, so as to prevent impurities in the water body from clogging the water inlet hole 10, thereby affecting the accuracy of the water quality detection data.

[0023] For example, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the driving structure includes a sliding tube 14 fixedly connected to the lower surface of the counterweight ring 4, the lower end of the sliding tube 14 is rotatably connected to a second rotating ring 15, the outer side of the second rotating ring 15 is provided with a second tooth structure 16, and the second tooth structure 16 is meshed with the first tooth structure 13 for transmission; The fixing rod 1 is provided with a first spiral guide groove 17 which is spirally arranged, and the inner side of the second rotating ring 15 is provided with a first guide block 18 which cooperates with the first spiral guide groove 17 . The first guide block 18 is located in the first spiral guide groove 17 and is slidably connected with the first spiral guide groove 17 .

[0024] When in use, the counterweight ring 4 moves downward, driving the sliding tube 14 and the second rotating ring 15 to move downward synchronously. When the second rotating ring 15 moves downward, it relies on the first guide block 18 to slide in the first spiral guide groove 17 to rotate the second rotating ring 15. When the second rotating ring 15 rotates, it relies on the second tooth structure 16 to mesh with the first tooth structure 13 to drive, thereby driving the first rotating ring 11 to rotate. When the first rotating ring 11 rotates, it drives the arc cleaning plate 12 to clean the outside of the protective shell 8, thereby ensuring the accuracy and convenience of water quality detection.

[0025] For example, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes that the inner wall of the protective shell 8 is provided with a vertically arranged driving rod 19, the lower end of the driving rod 19 passes through the protective shell 8 and is rotatably connected to the protective shell 8, the lower end of the driving rod 19 is fixedly connected to a rotating shaft 20, and the outer side of the rotating shaft 20 is fixedly connected to a plurality of groups of circumferentially distributed impellers 21; The driving rod 19 is provided with a spirally arranged second spiral guide groove 22, and the protective shell 8 is provided with a horizontally arranged cleaning ring 23. One end of the driving rod 19 passes through the cleaning ring 23 and is slidably connected to the cleaning ring 23. The inner side of the cleaning ring 23 is fixedly connected with a second guide block 24 corresponding to the second spiral guide groove 22. The second guide block 24 is slidably connected to the second spiral guide groove 22. The cleaning ring 23 is initially located at the inner bottom of the protective shell 8.

[0026] When in use, when the steel cable 3 is released, the counterweight ring 4 drives the detection tube 6 and the protective shell 8 to move downward synchronously. When the protective shell 8 moves downward, the impeller 21 at the bottom is squeezed and contacted with the water body, driving the impeller 21 to rotate. When the impeller 21 rotates, it drives the rotating shaft 20 and the driving rod 19 to rotate synchronously. When the driving rod 19 rotates, it drives the second guide block 24 to move by relying on the second spiral guide groove 22, so that the second guide block 24 moves upward in the second spiral guide groove 22. When the second guide block 24 moves upward, it drives the cleaning ring 23 to move upward synchronously, and relies on the upward movement of the cleaning ring 23 to clean the inner wall of the protective shell 8, so as to prevent the impurities adsorbed on the inner wall of the protective shell 8 from clogging the water inlet 10 and affecting the detection accuracy of the water body; When the water quality detection work is completed, the steel cable 3 is used to drive the counterweight ring 4 to reset and move upward. When the counterweight ring 4 is reset and moved upward, the second tooth structure 16 is again engaged with the first tooth structure 13 for transmission, driving the arc cleaning plate 12 to clean the outside of the protective shell 8, so as to facilitate the cleaning of the protective shell 8 when the counterweight ring 4 is reset and moved upward, so as to improve the accuracy of water quality detection when it is used again in the future; when the counterweight ring 4 stops moving, the cleaning ring 23 in the protective shell 8 relies on its own weight to make the second guide block 24 slide slowly in the second spiral guide groove 22, so as to facilitate the cleaning ring 23 to return to its initial state, and facilitate the counterweight ring 4 to move down again to drive the cleaning ring 23 to clean the inner wall of the protective shell 8 again.

[0027] For example, Figure 2 , Figure 4 , Figure 5 As shown, the present invention also includes that a plurality of drain pipes 25 are provided on the inner upper part of the protective shell 8, one end of the drain pipe 25 is connected to the inside of the protective shell 8, and the other end of the drain pipe 25 passes through the protective shell 8 and is connected to a one-way liquid outlet valve 26.

[0028] When in use, the second spiral guide groove 22 is used to drive the second guide block 24 to move, so that when the second guide block 24 moves upward, it drives the cleaning ring 23 to move upward synchronously, and the inner wall of the protective shell 8 is cleaned by relying on the upward movement of the cleaning ring 23. At the same time, relying on the extrusion force generated when the cleaning ring 23 moves upward, the impurities cleaned by the inner wall can be discharged through the drain pipe 25 and the one-way liquid outlet valve 26, preventing the impurities from being unable to be discharged through the water inlet hole 10 and falling into the protective shell 8 again, thereby further improving the accuracy of water quality detection and facilitating the cleaning of the inner wall of the protective shell 8.

[0029] For example, Figure 4 , Figure 7 As shown, the present invention also includes that the inner wall of the protective shell 8 is provided with a vertical positioning groove 27, and the outer side of the cleaning ring 23 is fixedly connected with a positioning block 28, and the positioning block 28 is located in the positioning groove 27 and is slidably connected to the positioning groove 27.

[0030] When in use, the vertically arranged positioning groove 27 can ensure the movement stability of the cleaning ring 23, prevent the cleaning ring 23 from rotating synchronously when the driving rod 19 rotates, and further facilitate cleaning the inner wall of the protective shell 8.

[0031] For example, Figure 1 As shown, the present invention also includes that a conical head 29 is provided at the lower end of the fixing rod 1 .

[0032] When in use, the conical head 29 facilitates the insertion of the fixing rod 1 into the water body to ensure the overall stability. At the same time, according to the location of the water area to be detected, the fixing rod 1 is inserted into the designated position and water quality detection at different depths is performed, further improving the convenience of detection.

[0033] When the present invention is in use, according to the location of the water area to be detected, when it is necessary to detect the water body, the conical head 29 is used to facilitate the fixing rod 1 to be inserted into the water body to ensure the overall stability. When it is necessary to detect different depths of the water body, the electric winder is used to release the steel cable 3, and the counterweight ring 4 is moved downward by its own weight. When the counterweight ring 4 moves downward, the longitudinal guide slider 30 slides in the guide slot 5 to ensure the downward stability of the counterweight ring 4 and facilitate the counterweight ring 4 to drive the detection tube 6 and the protective shell 8 to move downward synchronously. After the protective shell 8 moves down into the water body, the water enters the protective shell 8 through the water inlet hole 10, and the water quality of the water body is detected by the detection probe 9 at the same time; When the counterweight ring 4 moves downward, it drives the sliding tube 14 and the second rotating ring 15 to move downward synchronously. When the second rotating ring 15 moves downward, it relies on the first guide block 18 to slide in the first spiral guide groove 17 to rotate the second rotating ring 15. When the second rotating ring 15 rotates, it relies on the second tooth structure 16 to mesh with the first tooth structure 13 to drive, thereby driving the first rotating ring 11 to rotate. When the first rotating ring 11 rotates, it drives the arc cleaning plate 12 to clean the outside of the protective shell 8, so as to prevent impurities in the water body from clogging the water inlet hole 10, thereby affecting the accuracy of the water quality detection data; When the protective shell 8 moves downward, the impeller 21 at the bottom is squeezed and contacted with the water body, driving the impeller 21 to rotate. When the impeller 21 rotates, it drives the rotating shaft 20 and the driving rod 19 to rotate synchronously. When the driving rod 19 rotates, it drives the second guide block 24 to move by relying on the second spiral guide groove 22, so that the second guide block 24 moves upward in the second spiral guide groove 22. When the second guide block 24 moves upward, it drives the cleaning ring 23 to move upward synchronously. The vertically arranged positioning groove 27 can ensure the movement stability of the cleaning ring 23. The inner wall of the protective shell 8 is cleaned by relying on the upward movement of the cleaning ring 23 to prevent the impurities adsorbed on the inner wall of the protective shell 8 from clogging the water inlet hole 10 and affecting the detection accuracy of the water body. At the same time, relying on the squeezing force generated when the cleaning ring 23 moves upward, the impurities cleaned from the inner wall can be discharged through the drain pipe 25 and the one-way liquid outlet valve 26, preventing the impurities from being unable to be discharged through the water inlet hole 10 and falling into the protective shell 8 again, thereby further improving the accuracy of water quality detection and facilitating the cleaning of the inner wall of the protective shell 8; When the water quality detection work is completed, the steel cable 3 is used to drive the counterweight ring 4 to reset and move upward. When the counterweight ring 4 is reset and moved upward, the second tooth structure 16 is again engaged with the first tooth structure 13 for transmission, driving the arc cleaning plate 12 to clean the outside of the protective shell 8, so as to facilitate the cleaning of the protective shell 8 when the counterweight ring 4 is reset and moved upward, so as to improve the accuracy of water quality detection when it is used again in the future; when the counterweight ring 4 stops moving, the cleaning ring 23 in the protective shell 8 relies on its own weight to make the second guide block 24 slide slowly in the second spiral guide groove 22, so as to facilitate the cleaning ring 23 to return to its initial state, and facilitate the counterweight ring 4 to move down again to drive the cleaning ring 23 to clean the inner wall of the protective shell 8 again.
