[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5This utility model provides a technical solution: a multi-depth sampler for water sampling, including a fixed base 1 and a movable base 11. The bottom of the movable base 11 is provided with a sampling component and a cleaning component. The sampling component includes multiple sampling tubes 21 arranged circumferentially and fixedly connected to the bottom of the movable base 11; a waterproof box 22 fixedly connected to one side of the sampling tubes 21; a battery 23 fixedly connected to one side of the waterproof box 22; a first motor 24 fixedly connected to the top side of the waterproof box 22; a first rotating shaft 25 fixedly connected to the output end of the first motor 24; a main gear 26 fixedly connected to the outside of the first rotating shaft 25; a driven gear 27 connected to the main gear 26; a second rotating shaft 28 fixedly connected to the driven gear 27; and a component fixedly connected to the bottom of the second rotating shaft 28. The system includes a fixed connecting plate 29 and a fixed sealing cover 30 connected to one side of the connecting plate 29. A main gear 26 meshes with a driven gear 27. Both the first rotating shaft 25 and the second rotating shaft 28 are rotatably connected to a waterproof box 22. The waterproof box 22 protects the first motor 24 and the battery 23. The battery 23 powers the first motor 24. When the first motor 24 starts, it drives the main gear 26 to rotate, which in turn drives the driven gear 27 and the sealing cover 30 to rotate, opening the sampling tube 21 for sampling. The sealing cover 30, when reset, seals the sampling tube 21, preventing water ingress or leakage. Multiple sampling tubes 21 can be directly sampled at multiple depths without repeated retrieval, greatly improving sampling efficiency. The fixed base 1 is topped with... Support plates 51 are fixedly connected to both sides of the sampling tube 21. A third rotating shaft 52 is rotatably connected between the two support plates 51. A winding wheel 53 is fixedly connected to the outside of the third rotating shaft 52. A connecting rope 54 is fixedly connected to the outside of the winding wheel 53. A worm gear 55 is fixedly connected to the outside of the third rotating shaft 52. A worm 56 is provided at the bottom of the worm gear 55. A second motor 57 is fixedly connected to one end of the worm 56. The worm gear 55 meshes with the worm 56. The second motor 57 can drive the worm 56 to rotate, which in turn drives the worm gear 55 to drive the third rotating shaft 52 to rotate, which in turn drives the winding wheel 53 to rotate, which in turn drives the connecting rope 54 to wind up and unwind. This allows control of the overall depth of the sampling tube 21, facilitating multi-depth sampling. An opening 61 is provided at the top of the fixed base 1. The opening 61 has two sides... A guide cylinder 62 is rotatably connected to the sampling tube 21. The connecting rope 54 can contact the guide cylinder 62, which protects the connecting rope 54 from direct friction with the inner wall of the opening 61, preventing damage. A first sealing groove 71 is provided at the bottom of the sampling tube 21, and a first sealing ring 72 is fixedly connected inside the first sealing groove 71. The first sealing ring 72 can seal the tube, preventing water from entering and flowing out of the sampling tube 21. A drain pipe 81 is fixedly connected to one side of the sampling tube 21, and a fixing cap 82 is screwed to one side of the drain pipe 81. A second sealing groove 83 is provided on one side of the drain pipe 81, and a second sealing ring 84 is fixedly connected inside the second sealing groove 83. The fixing cap 82 can be unscrewed from the drain pipe 81, thus facilitating the drainage of water from the sampling tube 21.The second sealing ring 84 serves to seal the surface and prevent water from leaking out of the sampling tube 21.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The impurity removal component includes connecting grooves 31 respectively opened on both sides of the bottom of the sampling tube 21, connecting blocks 32 connected to the connecting grooves 31, filter plates 33 fixedly connected to the connecting blocks 32, and mounting components for fixing the filter plates 33. The connecting blocks 32 are inserted into the connecting grooves 31 and can be vertically inserted into the connecting grooves 31 to fix the filter plates 33 to the sampling tube 21. The filter plates 33 can filter impurities in the water, preventing impurities from entering the sampling tube 21 and ensuring the cleanliness of the water, which is convenient for subsequent testing. The mounting components include a first magnet 41 fixedly connected to the top of the connecting blocks 32, an adsorption groove 42 respectively opened at the top of the connecting grooves 31, and a second magnet 43 fixedly connected to the top of the adsorption groove 42. The first magnet 41 and the second magnet 43 attract each other and can fix the filter plates 33 by mutual attraction, thereby preventing the filter plates 33 from moving vertically and detaching from the sampling tube 21. At the same time, the filter plates 33 can be quickly removed for cleaning and maintenance.

[0026] Working principle: During operation, the connecting block 32 is inserted into the connecting groove 31, and the first magnet 41 and the second magnet 43 come into contact and attract each other to fix them in place, which can quickly fix the filter plate 33. The second motor 57 is started, which drives the worm gear 56 to rotate. The rotation of the worm gear 56 drives the worm wheel 55 to rotate, which in turn drives the winding wheel 53 to rotate, thereby releasing the connecting rope 54. The sampling tube 21 enters the water and is placed in a suitable position. Then, the second motor 57 is turned off, and the first motor 24 is started, which drives the first rotating shaft 25 and the main gear 26 to rotate. The main gear 26 drives the driven gear 27 and the second rotating shaft 28 to rotate, which in turn drives the connecting plate 29 and the sealing cover 30 to rotate. The rotation of the sealing cover 30 opens the sampling tube 21, allowing water to enter the sampling tube 21. Impurities are filtered through the filter plate 33, preventing impurities from entering the sampling tube 21. Within 1, after sampling is completed, the first motor 24 reverses, causing the sealing cover 30 to reset, thus sealing the sampling tube 21 to prevent water leakage or ingress. The second motor 57 starts, releasing the connecting rope 54 again, allowing the moving seat 11 and sampling tube 21 to continue descending. After descending to the appropriate position, the first motor 24 can start again for sampling. Since there are multiple sampling tubes 21, multi-depth sampling can be performed without repeatedly retrieving the sampling tubes 21. After all sampling is completed, the second motor 57 reverses, causing the moving seat 11 and sampling tube 21 to move upward and be removed from the water. Tightening the fixing cover 82 allows the water in the sampling tube 21 to be drained, facilitating the detection of water at different depths. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
