[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] In some embodiments, please refer to the accompanying drawings. Figures 1-6 A multi-dimensional water sample detection device includes a fixed plate 1, a connecting rod 2, an internal support fixing mechanism 3, a multi-station sampling mechanism 4, a receiving cylinder 5, a support base 6, and a fixing plate 7. The internal support fixing mechanism 3 is installed at the lower end of the fixed plate 1. The internal support fixing mechanism 3 includes a movable component 32 for controlling the contraction and expansion of multiple internal support plates 33, a fixed drive component 31 for controlling the movement of the movable component 32, and multiple internal support plates 33. The fixed drive component 31 is installed on the fixed plate 1, and the connecting rod 2 is installed below the fixed drive component 31. The movable component 32 is installed on the fixed drive component 31 and the connecting rod 2. Multiple internal support plates 33 are installed on the movable component 32. The outer ends of the internal support plates 33 are provided with anti-slip pads.

[0030] A receiving cylinder 5 is fixedly connected to the lower part of the connecting rod 2 via a mounting bracket; a water inlet is provided at the lower end of the receiving cylinder 5; a fixing plate 7 is fixedly installed in the middle of the receiving cylinder 5; a sampling port is provided in front of the fixing plate 7; a sampling station is provided in front of the fixing plate 7; waiting stations are provided on the left and right sides behind the fixing plate 7; a support base 6 is fixedly installed at the outer end of the receiving cylinder 5.

[0031] A multi-station sampling mechanism 4 for collecting water samples at different time periods is installed below the connecting rod 2 and inside the receiving cylinder 5. The multi-station sampling mechanism 4 includes a rotation drive assembly 41 for controlling the switching of the sampling component 42 between the sampling station and the waiting station, the sampling component 42, and a push cylinder 43. A part of the rotation drive assembly 41 is installed on the upper end of the fixed plate 1, and the other part of the rotation drive assembly 41 is connected to the fixed drive assembly 31, the connecting rod 2, the receiving cylinder 5, and the fixed plate 7. Multiple sampling components 42 are installed on the rotation drive assembly 41, and the sampling components 42 are evenly distributed in a circular array on the rotation drive assembly 41. The push cylinder 43 is fixedly installed at the front end of the receiving cylinder 5, and the output end of the push cylinder 43 is connected to the sampling component 42 at the sampling station. The sampling port located below the sampling component 42 at the sampling station is connected to the sampling port set in front of the fixed plate 7.

[0032] In this invention, the fixed drive assembly 31 controls the movement of the movable assembly 32. The movable assembly 32 drives multiple inner support plates 33 to unfold outward until the outer ends of the multiple inner support plates 33 abut against the inner wall of the sewer pipe. At this time, the receiving cylinder 5 is submerged in the water at the bottom of the sewer. Subsequently, the push cylinder 43 drives the sampling assembly 42, which is located at the sampling position, to move. The sampling assembly 42 samples the water in the receiving cylinder 5 through the sampling port set in front of the fixed plate 7. After sampling is completed, the rotation drive assembly 41 drives multiple sampling assemblies 42 to rotate simultaneously, so that the sampling assembly 42 moves to the waiting position on the right side behind the fixed plate 7 after sampling, and the sampling assembly 42 on the left side behind the fixed plate 7 rotates to the sampling position; and the next water sample sampling operation is carried out.

[0033] When the next sampling time period arrives, the push cylinder 43 operates again, driving the sampling component 42 in the sampling position to perform water sample collection. This operation is repeated until all sampling components 42 have completed water sample collection. At this point, water sample collection for different time periods throughout the day in the sewer is completed. After sampling is completed, the fixed drive component 31 operates, driving the movable component 32 to move. The movement of the movable component 32 causes multiple inner support plates 33 to retract inward, separating the inner support plates 33 from the inner wall of the sewer pipe. The device can then be pulled out. Through the cooperation of the fixed drive component 31, the movable component 32, and the inner support plates 33, the device can be fixed to the inner wall of the sewer, reducing the extra workload of manual entry into the sewer and improving the practicality of the device. Furthermore, through the cooperation of the rotating drive component 41 and the sampling component 42, the device can perform multiple sampling tests on water samples in the sewer pipe at different time periods, improving the accuracy of water sample testing.

[0034] like Figures 1-5 As shown, the fixed drive assembly 31 includes a lead screw 311, a first drive bevel gear 312, a first driven bevel gear 313, a first servo motor 314, guide rods 315, and a first upright plate 316.

[0035] like Figures 1-5 As shown, the movable component 32 includes a fixed ring 321, a sliding ring 322, a driven support rod 323, and an active support rod 324.

The sliding ring 322 is slidably connected to the guide rod 315. The inner ends of multiple active support rods 324 are hinged to the outer ends of the sliding ring 322, and the outer ends of the active support rods 324 are hinged to the upper inner end of the inner support plate 33. The inner ends of multiple driven support rods 323 are hinged to the outer ends of the fixed rings 321, and the outer ends of the driven support rods 323 are hinged to the inner end of the inner support plate 33. The lower end of the guide rod 315 is fixedly connected to the upper fixed ring 321.

[0036] like Figures 1-5 As shown, the rotation drive assembly 41 includes a second drive bevel gear 411, a second driven bevel gear 412, a second servo motor 413, a rotating rod 414, a rotating disk 415, a second upright plate 416, and a supporting crossbeam 417. The middle part of the rotating disk 415 is rotatably connected to the lower end of the connecting rod 2; the outer end of the rotating disk 415 is rotatably connected to the inner end of the receiving cylinder 5; the rotating rod 414 is disposed inside the lead screw 311 and the connecting rod 2, and the rotating rod 414 is rotatably connected to the interior of the lead screw 311 and the inner wall of the connecting rod 2; the supporting crossbeam 417 is fixedly installed on the upper end of the fixed disk 1, and the upper end of the rotating rod 414 is rotatably connected to the supporting crossbeam 417; the lower end of the rotating rod 414 is fixedly installed on the upper end of the fixed disk 1. The middle part of the fixed plate 7 is rotatably connected; the second driven bevel gear 412 is rotatably mounted on the support crossbeam 417, and the second driven bevel gear 412 is fixedly connected to the rotating rod 414; the second upright plate 416 is fixedly mounted on the upper left side of the fixed disk 1, the second driving bevel gear 411 is rotatably mounted on the right end of the second upright plate 416, the second servo motor 413 is fixedly mounted on the left end of the second upright plate 416, and the output end of the second servo motor 413 is fixedly connected to the second driving bevel gear 411; the second driving bevel gear 411 is meshed with the second driven bevel gear 412; multiple sampling components 42 are provided on the rotating disk 415; the lower part of the rotating rod 414 is fixedly connected to the rotating disk 415;

[0037] like Figure 6 As shown, the sampling assembly 42 includes a cylinder 421, a piston 422, a core rod 423, and a push plate 424. The cylinder 421 is detachably connected to the rotating disk 415. A sliding groove is provided inside the cylinder 421. The piston 422 is slidably connected to the sliding groove. The core rod 423 is fixedly connected to the upper end of the piston 422. The push plate 424 is fixedly installed on the upper end of the core rod 423. The output end of the push cylinder 43 is in contact with the push plate 424 at the sampling station. A feed port is provided at the lower end of the cylinder 421, and the sampling port provided on the fixed plate 7 is connected to the feed port of the cylinder 421 at the sampling station.

[0038] In this invention, the first servo motor 314 drives the first driving bevel gear 312 to rotate, which in turn drives the first driven bevel gear 313 to rotate, causing the lead screw 311 to rotate along with the driven bevel gear 313. At this time, the sliding ring 322 moves downwards along the guide rod 315. During this movement, it pushes the active support rod 324 upwards, causing the inner support plate 33 to rotate. The rotation of the inner support plate 33 then drives the driven support rod 323 upwards until the outer end of the inner support plate 33 abuts against the inner wall of the sewer pipe. At this point, the receiving cylinder... Body 5 is submerged in the water at the bottom of the sewer; then the push cylinder 43 works to push the push plate 424 at the sampling position upward. The push plate 424 works to drive the core rod 423 and piston 422 to move upward along the sliding groove set on the cylinder 421. At this time, the gas volume inside the cylinder 421 increases and the pressure decreases. The external atmospheric pressure will force the liquid in the container cylinder 5 into the interior of the cylinder 421 through the sampling port set on the fixed plate 7. After the liquid enters the container cylinder 5, the internal air pressure is still lower than the outside air pressure. The atmospheric pressure supports the liquid in the container cylinder 5, preventing it from flowing out.

[0039] After sampling is completed, the second servo motor 413 drives the second drive bevel gear 411 to rotate, and the rotation of the second drive bevel gear 411 drives the second driven bevel gear 412 to rotate, so that the rotating rod 414 rotates together with the second driven bevel gear 412. At this time, the rotating disk 415 will drive multiple cylinders 421 to rotate simultaneously, so that after sampling, the cylinders 421 move to the waiting position on the right side behind the fixed plate 7, and the cylinders 421 on the left side behind the fixed plate 7 rotate to the waiting position; and the next water sample sampling operation is carried out.

[0040] When the next sampling time period arrives, the push cylinder 43 works again to push the push plate 424, which is in the sampling position, to move upward to carry out water sample sampling. The above operation is repeated until all cylinders 421 have completed water sample collection. At this time, the water sample sampling operation of the sewer at different time periods of the day is completed.

[0041] Once sampling is complete, the first servo motor 314 drives the sliding ring 322 to move, causing multiple inner support plates 33 to retract inward and separate from the inner wall of the sewer pipe. Then, the device can be pulled out of the sewer by the support crossbeam 417.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
