It is sucked close to the second sampling tube 41, which causes the second sampling tube 41 to be blocked.

As a further expansion of this solution, as shown in FIG. 5 , the detection agent adding mechanism 5 includes a second through pipe 51 that is connected to the outer wall of the second sampling cylinder 23 . The second through pipe 51 extends from one end of the outer wall of the second sampling cylinder 23 A liquid storage cylinder 52 is provided in communication, and a sealing cover 53 is provided on the outer wall of the liquid storage cylinder 52.

The purpose of this arrangement is , so that the liquid in the inner cavity of the second sampling cylinder 23 will not enter the inner cavity of the liquid storage cylinder 52 through the second pipe 51. On the contrary, when the inner cavity of the liquid storage cylinder 52 is pressurized, the stored liquid can be The treatment agent inside the cylinder 52 flows into the inner cavity of the second sampling cylinder 23 through the second pipe 51 and the second one-way valve 54, and is used to mix and detect the sewage in the inner cavity of the second sampling cylinder 23, wherein the liquid storage The inside of the barrel 52 is provided with a second piston plate 55 that moves back and forth in the horizontal direction.

When the first piston plate 24 moves to the connection between the first pipe 106 and the top cover 21 and the second piston plate 55 is completely located on the left side of the liquid storage cylinder 52, the elastic membrane 109 expands slightly and does not block the first piston plate 24. Pass pipe 106; when the first piston plate 24 moves above the second sampling cylinder 23, and when the second piston plate 55 is completely located on the right side of the liquid storage cylinder 52, the elastic membrane 109 fully expands and blocks the first pass pipe 106 , so that when the first piston plate 24 is pushed to the right side of the second sampling tube 23, the second sampling tube 23 is blocked and cannot sample, and when the first piston plate 24 is located on the left side of the second sampling tube 23, the second sampling tube 23 is blocked. The sampling cylinder 23 can sample normally, so you can select whether the second sampling cylinder 23 participates in sampling by adjusting the position of the first piston plate 24, thereby meeting the requirements for separate sampling at different depths and different environments.

As another application scenario of the detection agent adding mechanism 5 of the present invention, by pushing and pulling the push plate 57, the second piston rod 56 can synchronously push the second piston plate 55 to move in the horizontal direction in the inner cavity of the liquid storage cylinder 52, and then the liquid storage cylinder 52 can be moved horizontally. The detection agent inside the liquid cylinder 52 is squeezed into the inner cavity of the second sampling cylinder 23, so that the detection agent and the sewage are fully mixed for detection. At the same time, the number of the liquid storage cylinders 52 is set to at least two, and the two liquid storage cylinders 52 are The tubes 52 are arranged in a longitudinal and linear equidistant state with respect to the outer wall of the second sampling tube 23, and a third through-tube 59 is provided in communication between the two liquid storage tubes 52.

Put the equipment into the sewage. The sewage enters the first sampling tube 101 from the second sampling tube 41 and the first sampling tube 102. The filter plate 103 filters the sewage so that it enters the inside of the first sampling tube 101 and interacts with the microbial detection probe. The impurity content in the water sample contacted by 104 is reduced, and the microbial detector 105 is started to detect the water sample entering the inner cavity of the first sampling cylinder 101 to detect the microbial content.

Start the biaxial motor 31 to drive the connecting rotating rod 32 and the threaded screw 33 to rotate synchronously. The connecting rotating rod 32 drives the first connecting rod 47 and the second connecting rod 48. The first connecting rod 47 drives the connected first scraper. 49 and the second scraper 410 rotate, so that the first scraper 49 rotates and scrapes on the inner wall of the first sampling tube 102, and the second scraper 410 rotates and moves at the bottom of the filter plate 103, thereby avoiding the need to pump water. When sampling, impurities block the filter plate 103 and the first sampling tube 102, affecting the smooth extraction of water samples.

The second connecting rod 48 drives the second sampling pipe 41 to rotate, and the threaded sleeve 42 moves up and down on the second sampling pipe 41, so that the threaded sleeve 42 drives the first support rod 43 to move linearly on the outer wall of the second sampling pipe 41, thereby following the The gradual descent of the threaded sleeve 42 can cause the first support rod 43 to gradually change from an inclined state to a horizontal state, and then expand the second support rod 44 and the stirring blade 45 outward, so that when the water sample is extracted, the first support rod 43 will be moved to the horizontal state. The impurities at the sampling tube 102 and the second sampling tube 41 are pushed out to prevent larger impurities from being sucked close to the second sampling tube 41 and causing the second sampling tube 41 to be blocked.

At the same time, the threaded screw rod 33 rotates to drive the adapter frame 36 to move up and down, so that the adapter frame 36 drives the first piston rod 22 to move up and down, and then the first piston rod 22 and the first piston plate 24 move the top cover 21 and the second sample The inner cavity of the cylinder 23 is pumping gas. When the push plate 57 is pushed, the push plate 57 and the liquid storage cylinder 52 are sucked together by the armature 60 and cannot rebound. The gas in the liquid storage cylinder 52 is discharged in advance without causing excess gas. Entering the second sampling tube 23 and the top cover 21, when the first piston plate 24 moves upward from the bottom, the gas in the second sampling tube 23 and the top cover 21 passes through the elastic membrane connecting tube 108, causing the elastic membrane 109 to expand. , when the first piston plate 24 rises and is limited by the limiting plate 28 , the gas is not enough to expand the elastic membrane 109 to completely block the first sampling tube 102 , thereby filtering the inside of the first sampling tube 101 by the filter plate 103 The filtered water sample is loaded into the inner cavity of the corresponding second sampling cylinder 23 through the first pipe 106. At this time, all the second sampling cylinders 23 are disassembled from the bottom of the top cover 21, and the detection agent is removed from the sealing cover 53. Push the push plate 57 in the adding liquid storage cylinder 52 to add the detection agent into the second sampling cylinder 23. A third pipe 59 is connected between the two liquid storage cylinders 52, so that the detection agent is added to the inner cavity of the second sampling cylinder 23. When squeezing in the detection agent, multiple liquid storage cylinders 52 can be arranged so that the detection agent is mixed in the sewage in layers. The cavities remain connected to each other, so that when the detection agent is added from the sealing cover 53, the multiple liquid storage cylinders 52 can replenish the detection agent synchronously, so that the water sample can be quickly detected and used, and there are many types of sewage detection agents. By taking multiple samples at one time, you can pour different detection agents into different second sampling tubes for testing, eliminating the need to repeatedly take water samples and repeatedly add detection agents. This can eliminate these tedious steps and conduct water sample testing more quickly.

When you want to take different areas separately or individually, push the corresponding push plate 57 to push the gas in the liquid storage cylinder 52 into the second sampling cylinder 23. At this time, the first piston plate 24 moves upward from the bottom. When a piston plate 24 rises and is limited by the limiting plate 28, the gas in the second sampling tube 23 and the top cover 21 passes through the elastic film connecting pipe 108, causing the elastic film 109 to expand. Since the gas in the second sampling tube 23 increases, the gas in the second sampling tube 23 increases. The expansion of the elastic membrane 109 completely blocks the first sampling tube 102, so the water sample cannot enter the corresponding second sampling tube 23. The excess gas enters the gas passage tube 25 through the constant pressure valve 26. When the pressure exceeds the pressure of the constant pressure valve, When the pressure is high, the constant pressure valve 26 opens, and the gas and pressure in the air cylinder 20 are discharged to the outside through the constant pressure valve 26. This allows separate water collection in different areas, avoiding the need to exchange sample barrels back and forth to cause leakage of water samples and affect the actual detection. .

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
