DETAILED DESCRIPTION

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figure 1-3 As shown, the utility model is a water quality sampling device suitable for different depths, including a floating boat 1, a water pump 2 is arranged above the floating boat 1, metal pipes 21 are connected on both sides of the water pump 2, one side of the metal pipe 21 is connected to a collection box 26, and the other side of the metal pipe 21 is connected to a rotary joint 22, and the other end of the rotary joint 22 is connected to a sampling tube 23. By turning on the water pump 2 switch, suction is generated at the sampling tube 23, and the water required for sampling can be extracted. The extracted water enters the collection box through the metal pipe 21, and the water sampling and collection work is completed. A rotary joint is arranged at the connecting end of the metal pipe 21 and the sampling tube 23, and the outside of the metal pipe 21 is rotatably connected to the rotary joint 22 through a bearing, and the winding roller 16 can be placed. When the sampling tube 23 is wound, the sampling tube 23 will not be bent between the metal pipe 21 and the metal pipe 21, thereby ensuring the integrity of the sampling tube 23 during the sampling process.

[0021] The floating boat 1 is provided with a mounting frame 13, and a first motor 14 is provided on the side of the mounting frame 13. A rotating shaft 15 is provided at the output end of the first motor 14. A winding roller 16 is fixedly sleeved on the outside of the rotating shaft 15, and a sampling tube 23 is provided on the winding roller 16. By turning on the switch of the first motor 14, the rotating shaft 15 at the output end of the first motor 14 starts to rotate in the mounting frame 13 through the bearing, and the winding roller 16 fixedly sleeved on the outside of the rotating shaft 15 can start to rotate synchronously, which can drive the sampling tube 23 arranged outside it to rotate, and then the sampling length of the sampling tube 23 can be adjusted, so as to facilitate the sampling of water quality at different depths.

[0022] A sleeve 3 is sleeved at the water inlet of the sampling tube 23, and a filter plate 24 is provided at one end of the sleeve 3 away from the sampling tube 23. The filter plate 24 arranged at the end of the sleeve 3 can filter impurities such as aquatic plants during the sampling process, prevent impurities in the water from entering the collection box 26, and prevent impurities from clogging and damaging the sampling device.

[0023] The sleeve 3 is provided with fixed plates 32 on both sides, and a second motor 33 is provided on one side of the fixed plate 32. A screw rod 34 is provided at the output end of the second motor 33. A slider 35 is threadedly connected to the screw rod 34. A cleaning brush 37 is provided above the slider 35. By turning on the switch of the second motor 33, the screw rod 34 at the output end of the second motor 33 starts to rotate in the fixed plate 32 through the bearing. The rotation of the screw rod 34 can drive the threaded slider 35 to move. A cleaning brush 37 is fixedly connected above the slider 35. The movement of the slider 35 can drive the cleaning brush 37 to move. The cleaning brush 37 is slidably connected to the filter plate 24. The bristle end of the cleaning brush 37 is in sliding contact with the surface of the filter plate 24. The movement of the cleaning brush 37 can drive the bristles on the surface to clean the surface of the filter plate 24, so as to avoid clogging of the surface of the filter plate 24 during water quality sampling, thereby interrupting the sampling, avoiding the need for workers to tediously clean the filter plate 24, bringing convenience to the workers' work and improving the sampling efficiency.

[0024] In the above scheme, a solar panel 11 is provided above the floating boat 1, and the solar panel 11 is connected to a battery 12. During the sampling process, the solar panel 11 can charge the battery 12, and the battery 12 provides energy to the electrical equipment, saving resources.

[0025] In the above solution, a driving propeller 17 is provided below the floating boat 1. By controlling the driving propeller 17, the moving position of the floating boat 1 on the water surface can be controlled.

[0026] In the above solution, a weight block 25 is fixedly mounted on the outside of the sampling tube 23. Through the weight block 25, the sampling tube 23 can reach water at any depth to sample water quality at different depths.

[0027] In the above solution, a water depth sensor 31 is fixedly provided on the outside of the casing 3, and the water surface at a desired depth can be sampled through the water depth sensor 31.

[0028] In the above scheme, a slide rod 36 is fixedly installed in the fixed plate 32, and the slide rod 36 is slidably connected to the slider 35. The setting of the slide rod 36 can limit the rotation of the slider 35 and ensure the stability of the slider 35 driving the cleaning brush 37 to slide.

[0029] In the above scheme,

[0030] Working principle:

[0031] This water quality sampling device is suitable for different depths. When working, the floating boat 1 is moved to the water surface where sampling is required by controlling the driving paddle 17. By turning on the switch of the first motor 14, the winding roller 16 starts to rotate, and the sampling tube 23 is transported downward. The sampling tube 23 is quickly moved to the inside of the water surface driven by the weight block 25, and reaches the water surface depth required for sampling through the water depth sensor 31. The water pump 2 is turned on, and the water pump 2 extracts water samples through the metal tube 21 and the sampling tube 23 to perform water quality sampling. During the sampling process, when the surface of the filter plate 24 is blocked, the second motor 33 is turned on, and the screw rod 34 at the output end of the second motor 33 starts to rotate, which can control the cleaning brush 37 to move, and the cleaning brush 37 removes foreign matter on the surface of the filter plate 24 to ensure that foreign matter blockage does not occur during the sampling process.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
