[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-5 A heavy metal sampling and filtration device shown in the figure comprises a sampling device body 1, wherein positioning mechanisms 2 are fixedly connected on all sides of the sampling device body 1, a buckle 3 is fixedly connected to one side of the sampling device body 1, a water level detection probe 4 is clamped in the buckle 3, and a controller 5 is fixedly connected to one end of the water level detection probe 4, a sampling seat 6 is fixedly connected to the front side of the sampling device body 1, three cavities 7 are horizontally opened in the sampling seat 6, a mounting seat 8 is fixedly connected to one side of the cavity 7, an electric valve 9 is connected through the sampling seat 6 and the mounting seat 8, and a sampling bottle 10 is connected to the other end of the mounting seat 8. The sampling device body 1 and the positioning mechanism 2 in this embodiment are both existing structures of the sampling and filtration device, and the water sample is drawn into the sampling box by the driving component in the sampling device body 1, so as to discharge the ultrapure water in the water tank, and the second power mechanism is arranged in the sample box, so as to draw the water sample containing heavy metals released by the bottom mud into the sample box when the first power mechanism discharges the ultrapure water in the water tank. When using the automatic sampling device for releasing heavy metals from lake sediments to collect sediments from lakes and rivers, the automatic sampling device for releasing heavy metals from lake sediments is placed on the sediment at the bottom of lakes and rivers. The water from lakes and rivers enters the sampling box after particulate matter is filtered out by filter paper. The ultrapure water in the water tank is then discharged by the first power mechanism. Since the concentration of heavy metals in the water is lower than that in the sediment, the heavy metals in the sediment will be released and diffused into the water, thereby allowing the heavy metals released and diffused from the sediment to enter the water in the sampling box through the sampling port covered and blocked by the filter paper to become water samples to be collected. The water samples in the sampling box are then drawn into the sample box by the second power mechanism to complete the collection of the water samples of heavy metals released from the sediment. The water level detection probe 4 on the front side of the sampling device body 1 can be used to perform real-time detection of the sampling water level of the sampling device. The multiple sampling bottles 10 in the sampling seat 6 are used for multi-level sample collection of the device.

[0026] One end of the water level detection probe 4 is fixedly connected to a water level sensor 11, and the external part of the controller 5 is connected to a power supply. By applying the existing water level detection technology of sensors, the water level sensor 11 in the water level detection probe 4 can perform real-time detection of the water level depth of the sampling device body 1 at the position, and obtain the detection sample depth of the sampling and filtration device.

[0027] The controller 5 is provided with a display screen, and the controller 5 is provided with control switches 12 having the same number as the cavities 7. The water level data detected by the water level detection probe 4 can be displayed and processed through the display screen. Then, the control switches 12 in the controller 5 are set and used in the same number as the cavities 7, so that each cavity 7 can control and process the switch state of the cavity 7 respectively, thereby realizing remote switch processing of the cavity 7.

[0028] The cavity 7 is connected with the mounting seat 8 and the electric valve 9, and the sampling bottle 10 is connected with the cavity 7. The cavity 7 is connected with the mounting seat 8 and the electric valve 9, which facilitates the pouring of external heavy metal water samples into the sampling bottle 10, thereby realizing multi-stage sampling of heavy metal water samples. The use of the mounting seat 8 in the cavity 7 facilitates the installation of the sampling bottle 10 and the sampling seat 6.

[0029] A threaded ring 13 is arranged at one end of the sampling bottle 10, and a threaded groove is opened on the inner side of the mounting seat 8. The threaded ring 13 is threadedly connected to the mounting seat 8 through the threaded groove. The threaded ring 13 is through-connected with the connecting pipe 14. The threaded ring 13 and the threaded groove are convenient for adding a threaded connection structure to the end of the sampling bottle 10, so that the sampling bottle 10 can be screwed into the threaded groove of the mounting seat 8 by rotating the sampling bottle 10, thereby fixing the position of the sampling bottle 10 and connecting the sampling bottle 10 with the connecting pipe 14.

[0030] The inner diameter of the cavity 7 is the same as the outer diameter of the mounting seat 8. The electric valve 9 includes a connecting tube 14 that is connected to the sampling seat 6. One end of the connecting tube 14 is fixedly connected to a connecting seat 15. A sealing plate 16 is rotatably connected to the connecting seat 15. One side of the sealing plate 16 is fixedly connected to a motor 17. By setting the mounting seat 8 in the cavity 7, it is convenient to increase the threaded connection end inside the cavity 7, which is convenient for connecting the sampling bottle 10 to the cavity 7. By using the connecting seat 15, the sealing plate 16 and the motor 17 in the electric valve 9, it is possible to increase the electric switch structure outside the sampling seat 6. The motor 17 drives the rotation of the sealing plate 16, which can control the switching state of the connecting seat 15, and then automatically adjust the switch of the connecting tube 14.

[0031] The diameter of the sealing plate 16 is the same as the inner diameter of the connecting seat 15. The outside of the sealing plate 16 is covered with a rubber sleeve. The sealing plate 16 fits the inner wall of the connecting seat 15 so that the sealing plate 16 can close the connecting seat 15. The rubber sleeve is used for sealing the sealing plate 16 and the inner wall of the connecting seat 15.

By using the water level sensor 11 at the end of the water level detection probe 4, the user on the river surface can obtain the water level depth of the sampling device body 1 through the data displayed on the display screen. The user can control the electric valve 9 at different positions through the control switch 12 at different positions in the controller 5 to open or close the sampling bottle 10. When opening, the sealing plate 16 is driven to rotate by the motor 17 in the electric valve 9, so that the sealing plate 16 is arranged in parallel in the connecting seat 15. The connecting seat 15 is opened, so that the external water source is pressed into the sampling bottle 10 under the influence of pressure, and then the sampling bottle 10 is opened by the control When the switch 12 is closed, the sampling bottle 10 can be closed to obtain the heavy metal water sample at the water level. Then, through the arrangement of the three sampling bottles 10 and the electric valve 9 on the sampling device body 1, the sampling and filtration device can perform multi-level sample extraction. The sampling device body 1 can punch heavy metal water samples of different depths, which increases the convenience of water sample collection and improves the convenience of sampling and filtration device. After the sampling device is completed, the open end of the sampling bottle 10 is set upward, and the sampling bottle 10 is rotated. Through the rotation of the threaded ring 13 at the end of the sampling bottle 10 and the threaded groove in the mounting seat 8, the sampling bottle 10 can be screwed out of the mounting seat 8 to take out the heavy metal sample, so that the sampling device body 1 can perform multi-level heavy metal water sample filtration, which increases the ease of operation of the filtration device, improves the convenience of use of the filtration device, and is practical.
