[0002] Water sampling refers to collecting water samples of contaminated water bodies, and through analysis and determination, obtaining basic data of water body pollution. The water sample for analysis should be representative and can reflect the chemical composition and characteristics of the water body. The method, position, time and frequency of sampling are determined according to the characteristics of the water body and the analysis purpose.

[0003] Water sampling usually uses a sampling pipe, and the material of the sampling pipe has many kinds, such as disposable plastic material and reusable glass material. For the reusable sampling pipe, it usually needs to be cleaned deeply after one use, and because the water quality of the sample usually has a certain pollution (such as oil pollution), manual brushing is usually required. The number of samples is usually very large, manual cleaning is not only time-consuming and laborious, but also ineffective, and after cleaning, it needs to be dried and dried, and the cleaning cycle is long. Therefore, a more efficient sampling pipe cleaning device can be designed. SUMMARY

Specific implementation

[0022] Embodiment

[0023] The following is further illustrated in conjunction with specific embodiments, such as the accompanying Figure 1 - the accompanying Figure 7 As shown in the drawings, the sampling pipe cleaning device for water quality detection of the embodiment comprises a shell 11 with an open upper end, a cover 12 arranged at the upper end of the shell 11, a support plate 13 horizontally arranged in the shell 11, a water leakage hole 14 arranged on the support plate 13, a plurality of water spraying pipes 21 vertically arranged on the support plate 13, a water spraying hole 22 arranged on the side wall of the water spraying pipe 21, a water supply pipe 23 in communication with the lower ends of the plurality of water spraying pipes 21, an air compressor in communication with the end of the water supply pipe 23 away from the water spraying pipe 21, a conduit 24 connected to the side wall of the water supply pipe 23, and a water source connected to the conduit 24; the sampling pipe 40 is inverted on the support plate 13, and one water spraying pipe 21 is inserted into one sampling pipe 40. Specifically, in use, the sampling pipe 40 after use and pouring out of water sample is inverted on the water spraying pipe 21, then the cover 12 is covered on the shell 11, so that the cover 12 is pressed on the bottom of the sampling pipe 40, and the air compressor is started, and high-speed airflow is sent into the water spraying pipe 21 through the water supply pipe 23. In this process, because the airflow in the water supply pipe 23 has high flow rate and low air pressure, water in the water source can be sucked into the water supply pipe 23 through the conduit 24, and then sent into the water spraying pipe 21, and sprayed out of the water spraying hole 22 to clean the inner wall of the sampling pipe 40. The cleaned water is discharged through the water leakage hole 14 on the support plate 13, and after cleaning, the water supply of the conduit 24 is cut off (or the water source is closed), and the sampling pipe 40 can be dried by the air compressor. In this way, the sampling pipe 40 can be flushed without using a water pump (the conduit 24 can be directly connected to a faucet), and the sampling pipe 40 after flushing can be dried, so that the cleaning efficiency is higher, and the sampling pipe 40 can be quickly put into use after cleaning.

[0024] The sidewall of the water supply pipe 23 in the embodiment is communicated with a connecting pipe 25, and the connecting pipe 25 is connected with a liquid storage tank 26. Valves are arranged on the connecting pipe 25 and the conduit 24. The valves are automatic valves. Specifically, different cleaning agents such as alcohol and dishwashing liquid can be stored in different liquid storage tanks 26, so that the sampling pipe 40 can be better cleaned, and the use amount and use timing of the cleaning agent can be controlled through the valves.

[0025] The lower end of the water spraying pipe 21 in the embodiment is internally provided with a water blocking valve 30. The water blocking valve 30 comprises a hollow blocking block 31 arranged in the water spraying pipe 21, a water outlet hole 32 arranged at the upper end of the blocking block 31, a water inlet hole 33 arranged at the lower end of the blocking block 31, a floating ball 34 arranged in the blocking block 31, and a top rod 35 connected with the upper side of the floating ball 34. The diameter of the floating ball 34 is smaller than the diameter of the internal space of the blocking block 31, and the diameter of the floating ball 34 is larger than the diameter of the water outlet hole 32. The upper end of the top rod 35 extends outward after penetrating through the upper end of the water spraying pipe 21. The top rod 35 is in sliding connection with the upper end of the water spraying pipe 21. Specifically, the water blocking valve 30 functions as follows: when there is no sampling pipe 40 placed on the water spraying pipe 21, the water spraying pipe 21 does not spray water. The operating principle is as follows: when there is no sampling pipe 40 on the water spraying pipe 21, the water supply pipe 23 sends water into the water spraying pipe 21, and the water flow lifts the floating ball 34, and the top rod 35 is in abutment with the inner top wall of the cover body 12. At this time, the floating ball 34 is blocked at the water outlet hole 32 (as shown in FIG. 6), so that water cannot enter the water spraying pipe 21. When there is a sampling pipe 40 on the water spraying pipe 21, the floating ball 34 and the top rod 35 are lifted upward, and the top rod 35 is in abutment with the inner bottom wall of the sampling pipe 40. At this time, the floating ball 34 cannot reach the water outlet hole 32, and there is a gap between the floating ball 34 and the water outlet hole 32 (as shown in FIG. 7), so that the water flow can enter the water spraying pipe 21 through the gap. Figure 6 Figure 7

[0026] The floating ball 34 and the top rod 35 in the embodiment are made of hard plastic material. Specifically, the water flow can more easily lift the floating ball 34 and the top rod 35.

[0027] The inner top wall of the cover body 12 in the embodiment is provided with a plurality of limiting rings 15, one limiting ring 15 is arranged directly above one water spraying pipe 21, and the bottom of one sampling pipe 40 is clamped in one limiting ring 15. Specifically, after the cover body 12 is covered on the shell 11, the bottom of the sampling pipe 40 is clamped in the limiting ring 15, so that the sampling pipe 40 can be better limited and prevented from shaking.

[0028] ​​In summary, the sampling tube cleaning device for water quality detection of the embodiment is used to pour the sampling tube 40, which has been used and has water sample poured out, upside down on the water spraying pipe 21, then cover the cover 12 on the shell 11, press the cover 12 on the bottom of the sampling tube 40, start the air compressor, send the high-speed airflow in the water spraying pipe 21 through the water supply pipe 23, in the process, because the airflow in the water supply pipe 23 has high flow rate and low air pressure, the water in the water source can be sucked into the water supply pipe 23 through the conduit 24, then sent into the water spraying pipe 21, sprayed from the water spraying hole 22, clean the inner wall of the sampling tube 40, the cleaned water is discharged through the water leakage hole 14 on the support plate 13, after the cleaning is completed, cut off the water supply of the conduit 24 (or close the water source), the sampling tube 40 can be blown dry through the air compressor. In this way, the sampling tube 40 can be flushed without using the water pump, and the sampling tube 40 after flushing can be blown dry, the cleaning efficiency is higher, and after the cleaning is completed, the sampling tube 40 can be quickly put into use.
