[0019] In one embodiment, Figure 1-3 As shown, the automatic sand discharge device of the water sampling device comprises a water sampling tube 1, water inlets 2 are provided on the left and right sides of the water sampling tube 1 and near the top, a filter screen 3 is fixedly embedded in the water inlet 2, a sealing tube 4 is movably sleeved on the top of the water sampling tube 1, the water inlet 2 is arranged on the inner side of the sealing tube 4, the left and right sides of the top of the water sampling tube 1 are fixedly connected with first cylinders 5, the telescopic ends of the two first cylinders 5 are respectively fixedly connected with the left and right sides of the top surface of the inner wall of the sealing tube 4, the bottom of the water sampling tube 1 is fixedly sleeved with a collecting tube 6, and the water sampling tube 1 is bottom The water sampling tube 1 has an opening structure, with fixing holes on the left and right sides of the top, and the second cylinders 7 are fixedly sleeved in the two fixing holes. The telescopic ends of the second cylinders 7 penetrate into the water sampling tube 1, and the telescopic ends of the two second cylinders 7 are commonly fixedly connected with a first sealing plate 8. A through hole 9 is provided in the middle of the first sealing plate 8. A third cylinder 10 is fixedly connected to the middle of the top surface of the inner wall of the water sampling tube 1, and the telescopic end of the third cylinder 10 is fixedly connected to the second sealing plate 11, and the second sealing plate 11 is inserted into the through hole 9.

[0020] In order to facilitate the control of the operation of the first cylinder 5, the second cylinder 7, and the third cylinder 10, a remote sensing device 12 is fixedly connected to the left side of the top surface of the water sampling cylinder 1, and the first cylinder 5, the second cylinder 7, and the third cylinder 10 are all electrically connected to the remote sensing device 12, and the first cylinder 5, the second cylinder 7, and the third cylinder 10 are all electrically connected to an external power supply.

[0021] In order to conveniently discharge the water after the sediment is removed from the water sampling tube 1 , a water outlet pipe 13 is fixedly connected to the left side of the water sampling tube 1 near the bottom, and a butterfly valve 14 is installed on the water outlet pipe 13 .

[0022] In order to facilitate the removal of mud and sand from the collecting barrel 6, a drainage opening 15 is opened at the bottom of the right side of the collecting barrel 6, and a sealing block 16 is inserted into the drainage opening 15. A sealing rubber ring is sleeved on the surface of the sealing block 16, and a pull ring 17 is fixedly connected to the left side of the sealing block 16. The sealing block 16 is taken out of the drainage opening 15 by pulling the pull ring 17, so that the mud and sand in the collecting barrel 6 can be discharged from the drainage opening 15.

[0023] In order to facilitate putting the device into water and taking it out of water later, a lifting ring 18 is fixedly connected to the top surface of the sealing cylinder 4 , and a lifting rope 19 is wound around the lifting ring 18 .

[0024] In order to increase the buoyancy of the device in water and thus reduce the sinking speed of the device in water, a floating plate 20 is fixedly connected to the bottom surface of the collecting tube 6 , and floating blocks 21 are fixedly connected to the four corners of the bottom surface of the floating plate 20 .

[0025] Working principle: When the utility model is used, the device is first put into the water until the device falls to the bottom of the water, and then the floating plate 20 can increase the buoyancy of the device in the water, thereby reducing the speed of the device falling in the water, and then the remote sensing device 12 is controlled on the water surface, and the remote sensing device 12 starts the first cylinder 5, and the first cylinder 5 pushes the sealing tube 4 to rise. After the sealing tube 4 rises, the water inlet 2 is exposed, and water will enter the water collection tube 1 from the water inlet 2. The filter 3 filters larger debris in the water to avoid larger debris. The object enters the water sampling tube 1, and then the water in the water sampling tube 1 will contain relatively small silt, and then wait for the silt in the water to gradually sink, and the sinking silt will fall into the collecting tube 6. When the silt is completely settled on the bottom surface of the inner wall of the collecting tube 6, the remote sensing device 12 starts the second cylinder 7, and the second cylinder 7 pushes the first sealing plate 8 down until the first sealing plate 8 is located at the bottom of the water outlet pipe 13, blocking the bottom of the water sampling tube 1, and then the remote sensing device 12 starts the third cylinder 10, and the third cylinder 10 pushes The second sealing plate 11 is moved down until the second sealing plate 11 is re-inserted into the through hole 9 to block the through hole 9. At this time, even if the device shakes, the silt in the collecting tube 6 will not enter the water sampling tube 1. Then, the butterfly valve 14 on the outlet pipe 13 is twisted to discharge the water in the water sampling tube 1 after the silt is removed, thereby ensuring the purity of the collected water sample, reducing the interference factors in the subsequent analysis, and improving the accuracy and reliability of the data. The sealing block 16 is taken out from the drainage opening 15 by pulling the pull ring 17, so that the silt in the collecting tube 6 can be discharged from the drainage opening 15. When the device is placed in the water, first, the floating plate 20 and the floating block 21 can greatly enhance the buoyancy of the device in the water, thereby reducing the speed of the device descending in the water and reducing the impact force when the device falls on the river bottom. At the same time, when the device falls on the river bottom, the bottom surface of the four floating blocks 21 contacts the river channel, reducing the bottom surface of the device in contact with the river bottom, reducing the silt splashed when the device falls on the river bottom, thereby effectively reducing the silt entering the water sampling tube 1 with the water.

[0026] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
