[0025] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] Embodiment 1:

[0027] A water conservancy water quality sampling device includes a box body 1 and a box cover 2. The inner cavity of the box body 1 is divided into a power cavity 5, a collection cavity 6, and a storage cavity 7 by a first partition 3 and a second partition 4. A servo pump 8, a power supply, and a control component are arranged inside the power cavity 5. The power supply provides power to the servo pump 8, and the servo pump 8 is controlled to be switched on and off through the control component. The servo pump 8 is fixedly installed in the power cavity 5, and the water inlet end of the servo pump 8 is fixedly connected to one end of a water inlet pipe 9. The other end of the water inlet pipe 9 extends to the outside of the box body 1 and is threadedly connected to a water absorption component 17;

[0028] The water outlet end of the servo pump 8 is fixedly connected to one end of a water outlet pipe 10. The other end of the water outlet pipe 10 is fixedly connected to a classification collection component arranged in the collection cavity 6. The classification collection component is used for the collection and storage of various water qualities.

[0029] The classification collection component includes a water outlet branch pipe 11 and a first valve 12. The water outlet branch pipe 11 is composed of multiple branch pipes. First valves 12 are arranged at the ends of the multiple branch pipes, and the first valves 12 control the flow direction of the water in the water outlet pipe 10.

[0030] The classification collection component further includes a water outlet 13, a second valve 14, and a collection bottle 15. The water outlet 13 is arranged at the center of the water outlet branch pipe 11, and a second valve 14 is arranged on the water outlet 13. The collection port of the collection bottle 15 is threadedly connected to the bottom end of the water outlet 13.

[0031] In this embodiment, by arranging a classification collection component in the collection cavity 6, the collection and storage of multiple types of water quality are realized. By adjusting the first valves 12 and the second valves 14 on the multiple branch pipes of the water outlet branch pipe 11, the water in the water outlet pipe 10 is respectively collected into the collection bottle 15 through different branch pipes. After the collection is completed, due to the threaded connection between the water outlet 13 and the collection bottle 15, it is convenient to disassemble the collection bottle 15, and the collection bottle 15 is sealed and stored in the storage cavity 7 through the bottle cap, thus facilitating the operation of the staff, improving the classification collection of different types of water quality, and improving work efficiency.

[0032] Embodiment Two:

[0033] Based on Embodiment One, the water absorption component 17 mentioned in Embodiment One is described:

[0034] The water absorption component 17 includes a water absorption hose 171 and a filtering water absorption head 172. The connecting end of the water absorption hose 171 is threadedly connected to the water inlet pipe 9, and the other end of the water absorption hose 171 is equipped with a filtering water absorption head 172. Scale lines can be arranged on the outer side of the water absorption hose 171. By adjusting the positions of the lead block 174 and the float 176 according to the scale lines, it is convenient to sample water at different depths.

[0035] The water absorption assembly 17 further includes a stop block 173, a lead block 174, an external hanging block 175 and a float 176. The stop block 173 and the external hanging block 175 are made of rubber and are slidably connected to the outer side of the water absorption hose 171 inside. The inside of the lead block 174 is slidably connected to the outer side of the water absorption hose 171 and is located between adjacent stop blocks 173. A float 176 is arranged on the external hanging block 175, and the float 176 is used to ensure the suspension of the filtering water absorption head 172 in water.

[0036] In this embodiment, by setting the water absorption assembly 17, the collection of water at different depths is realized. By adjusting the position of the external hanging block 175 on the water absorption hose 171, the position of the float 176 is adjusted, so as to realize the sampling collection of water at different depths. The filtering water absorption head 172 is suspended in water for sampling collection by the action of the float 176, and the lead block 174 can drive the filtering water absorption head 172 and the water absorption hose 171 to sink.

[0037] A drain pipe 16 is arranged on one side of the bottom of the collection chamber 6, and a third valve 20 is arranged on the drain pipe 16. The collection chamber 6 is used to collect the redundant water in the water outlet branch pipe 11, and the redundant water is discharged out of the box body 1 through the drain pipe 16.

[0038] A hose collection tray 18 and a clamping block 19 are arranged on the inner side of the box cover 2, and the hose collection tray 18 and the clamping block 19 are used for storing the water absorption assembly 17.

[0039] Working principle: First, open the box cover 2 and take out the water absorption hose 171 inside it from the hose collection tray 18. After the connection end of the water absorption hose 171 is threadedly connected and fixed to the water inlet pipe 9 outside the box body 1, adjust the lead block 174 and the float 176 to appropriate positions according to the water depth, and then throw the water absorption hose 171 into the water. Use the position of the float 176 to sample the water quality at different depths. The farther the float 176 is from the filtering water absorption head 172, the deeper the filtering water absorption head 172 sinks. On the contrary, the shallower the sampling water quality depth of the filtering water absorption head 172. Ensure the suspended state of the filtering water absorption head 172 through the action of the float 176, and ensure the balance state of the filtering water absorption head 172 and the water absorption hose 171 in the water through the position of the lead block 174, reducing inclination or distortion. Adjust the lead block 174 to a position close to the filtering water absorption head 172, so that the filtering water absorption head 172 sinks faster, and vice versa slower. Open the first valve 12 and the second valve 14 on one branch pipe, and drive the servo pump 8 to pump water through the water absorption hose 171 into the water outlet pipe 10, and collect the water into the collection bottle 15 through the branch pipe with the valve opened. According to the scale line on the collection bottle 15, close the valve and the servo pump 8 at any time. When sampling other water quality, close the first valve 12 and the second valve 14 on the previous branch pipe, open the valve on the other branch pipe, and start the servo pump 8 to sample the water quality. During the sampling process of the previous water quality, there will more or less be residual water from the previous water quality sampling in the water pipe. At this time, do not install the collection bottle 15 first. After discharging a part of the water from the water outlet 13, then install and fix the collection bottle 15 to collect it, ensuring the quality of sampling different water quality classifications. After the collection is completed, remove the collection bottle 15 and seal it with the bottle cap and place it in the storage cavity 7. At this time, open the first valve 12 and the second valve 14 on the water outlet branch pipe 11 to discharge the excess water in the pipe into the collection cavity 6, and then open the third valve 20 on the drain pipe 16 to discharge the water in the collection cavity 6. After the sampling work is completed, disassemble and separate the water absorption assembly 17 from the water inlet pipe 9, wind the water absorption hose 171 of the water absorption assembly 17 around the hose collection tray 18, and finally snap the filtering water absorption head 172 into the block 19 to realize the storage of the water absorption assembly 17.
