Technical Field

[0001] This utility model relates to the field of water sampling technology, and more specifically, to a water pollution detection and sampling device. Background Technology

[0002] A water pollution detection sampling device is a specialized tool used to collect water samples for water quality analysis and pollution detection. An existing water sampler for water body detection, with publication number CN222105121U, includes a sampling frame, a drive unit, a hanging rope, and a sampler. The drive unit is mounted on the upper surface of the sampling frame, the hanging rope is connected to the side of the drive unit, the sampler is connected to the bottom of the hanging rope, a sampling port is connected to the left side of the sampler, and a water inlet is connected to the right side of the sampler.

[0003] However, in the above scheme, wastewater will remain on the outer wall of the sampler after sampling. When the same sampler is used at different sampling points, the pollutants from the previous sampling point may contaminate the subsequent sampling points, resulting in inaccurate test results. Utility Model Content

[0004] The main objective of this invention is to provide a water pollution detection and sampling device that can effectively solve the problems in the prior art where wastewater remains on the outer wall of the sampler after sampling, and where the same sampler may cause contamination of subsequent sampling points by pollutants from previous sampling points when used at different sampling points, leading to inaccurate test results.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1-6 As shown, a water pollution detection and sampling device includes a support frame 1, an avoidance groove 2 is provided through the upper surface of the support frame 1, and a sampling component 3 for sampling is provided on the upper surface of the support frame 1.

[0028] A cleaning component 4 for cleaning is provided between the two sides of the inner wall of the support frame 1;

[0029] Both sides of the lower surface of the support frame 1 are fixedly installed with base plates 101, and both sides of the upper surface of the two base plates 101 are provided with mounting holes 102.

[0030] Sampling component 3 includes two support plates 301, which are fixedly installed on both sides of the upper surface of support frame 1. A crossbar 302 is rotatably installed between the two support plates 301. A winch 303 is sleeved in the middle of the crossbar 302. A wire rope 304 is provided on the outer wall of the winch 303. A sampling bottle 305 is provided at the lower end of the wire rope 304.

[0031] One of the support plates 301 has a first motor 306 fixedly installed on one side, and one end of the crossbar 302 passes through the support plate 301 and is fixedly connected to the output shaft end of the first motor 306.

[0032] The cleaning assembly 4 includes two horizontal plates 401, which are fixedly installed on both sides of the inner wall of the support frame 1. An annular plate 402 is fixedly installed between the two horizontal plates 401. A rotating ring 404 is rotatably installed in the annular plate 402 via a bearing 403. A cavity 405 is opened in the rotating ring 404.

[0033] A water inlet pipe 406 is fixedly installed on the upper surface of the rotating ring 404, and several water outlet pipes 407 are fixedly installed on the inner wall of the rotating ring 404.

[0034] The staff starts the first motor 306, causing its output shaft to drive the crossbar 302 to rotate. The rotating crossbar 302 drives the winch 303 to rotate, causing one end of the wire rope 304 to lower the sampling bottle 305. After the sampling bottle 305 samples the sewage, the staff controls the output shaft of the first motor 306 to reverse, causing the sampling bottle 305 to reset. After the sampling bottle 305 resets, the staff pours disinfectant into the inlet pipe 406. The disinfectant is then sprayed onto the outer wall of the sampling bottle 305 through the outlet pipe 407, thereby disinfecting the outer wall of the sampling bottle. This prevents the contaminants from the previous sampling point from contaminating subsequent sampling points when the same sampler 305 is used at different sampling points, which could lead to inaccurate test results.

[0035] In another embodiment of this utility model, a horizontal pipe 5 is fixedly installed through one side of the support frame 1, and one end of the horizontal pipe 5 is fixedly connected to the water inlet pipe 406 through a flexible hose 6.

[0036] By setting up a horizontal pipe 5 and a flexible hose 6, after the staff fills the horizontal pipe 5 with disinfectant, the disinfectant enters the water inlet pipe 406 through the flexible hose 6.

[0037] In another embodiment of the present invention, an external toothed ring 7 is sleeved on the outer wall of the rotating ring 404;

[0038] A second motor 8 is fixedly installed on one side of the lower surface of one of the horizontal plates 401. The output shaft of the second motor 8 passes through the horizontal plate 401 and is fitted with a first gear 9. The first gear 9 meshes with the external gear ring 7.

[0039] The staff started the second motor 8, which caused its output shaft to drive the first gear 9 to rotate. Under the meshing action of the first gear 9 and the external gear ring 7, the rotating ring 404 rotated back and forth, increasing the spray range of the disinfectant and improving the disinfection efficiency.

[0040] In another embodiment of this utility model, a round rod 10 is rotatably installed between the two sides of the inner wall of the support frame 1. A rotating plate 11 is sleeved on the body of the round rod 10. A groove 12 is opened on one side surface of the rotating plate 11. A drainage hole 13 is opened through one side surface of the inner wall of the groove 12. A cylinder 15 is fixedly installed on one side of the support frame 1 through a bracket 14. A rack 16 is fixedly installed on the output end of the cylinder 15. One end of the round rod 10 passes through the support frame 1 and is sleeved with a second gear 17. The second gear 17 meshes with the rack 16.

[0041] The staff starts the cylinder 15, which drives the rack 16 to move. Under the meshing action of the rack 16 and the second gear 17, the rotating plate 11 rotates, allowing the disinfectant to fall into the groove 12. Then, the staff removes the blockage in the drain hole 13, allowing the water to flow out to the corresponding location, making it convenient for the staff to recycle the disinfectant.

[0042] The working principle of this water pollution detection and sampling device:

[0043] In use, the staff starts the first motor 306, causing its output shaft to drive the crossbar 302 to rotate. The rotating crossbar 302 drives the winch 303 to rotate, causing one end of the wire rope 304 to lower the sampling bottle 305. After the sampling bottle 305 samples the sewage, the staff controls the output shaft of the first motor 306 to reverse, causing the sampling bottle 305 to reset. After the sampling bottle 305 resets, the staff pours disinfectant into the inlet pipe 406. The disinfectant is then sprayed onto the outer wall of the sampling bottle 305 through the outlet pipe 407, thereby disinfecting the outer wall of the sampling bottle. This prevents the contaminants from the previous sampling point from contaminating subsequent sampling points when the same sampler 305 is used at different sampling points, which could lead to inaccurate test results.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
