[0003] In water treatment plants, multiple consecutive microbial tests are required to continuously monitor the water quality. However, existing testing devices leave residues of previous water samples after each test, which leads to sample mixing during continuous testing and affects the accuracy of the test results. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a multi-channel continuous detection device for aquatic microorganisms. This addresses the technical problem that current detection devices leave residual water samples from the previous test, which leads to sample mixing during continuous testing and affects the accuracy of the test results.
[0005] To achieve the objectives of this utility model, the technical solution adopted is as follows: A multi-channel continuous detection device for microorganisms in water is designed, comprising a support plate, a crossbar, a drainage trough, and a distilled water tank. A vertically oriented lifting groove is provided on the side wall of the support plate. A threaded rod is rotatably connected to the inner side of the lifting groove. The threaded rod passes through a threaded block and is threadedly connected to the threaded block. The outer side wall of the threaded block is fixedly connected to one end of the crossbar. Several detection chambers are evenly distributed on the inner side of the crossbar. A small water pump is fixedly connected to the top of the crossbar directly above each detection chamber. The outlet of the small water pump is connected to the interior of the detection chamber, and the inlet of the small water pump is connected to a metal... The water pipe has a rubber water pipe connected to its lower end, and the rubber water pipe and the metal water pipe are connected. An upper rinsing tank is fixedly connected to the surface of the support plate on one side of the lifting tank. Several cleaning pipes are evenly distributed at the bottom of the upper rinsing tank. A lower rinsing tank is fixedly connected to the surface of the support plate directly below the upper rinsing tank. A second small water pump is fixedly connected to the top of the distilled water tank. The outlet of the second small water pump is fixedly connected to one end of the water pump pipe and is connected to it. Two branches of the other end of the water pump pipe pass through the surface of the support plate and are located directly above the upper rinsing tank and the lower rinsing tank near the end of the support plate, respectively. A second electrically controlled valve is sealed at the connection between the water pump pipe and the support plate.
[0006] Preferably, a water quality analyzer is vertically inserted into the top of the support plate on one side of the No. 1 small water pump, and the bottom of the water quality analyzer is located at the bottom of the inner side of the testing chamber.
[0007] Preferably, a drainage trough is fixedly connected to the bottom of the crossbar, and a No. 1 electrically controlled valve is sealed between the detection chamber and the drainage trough, and the detection chamber is connected to the drainage trough.
[0008] Preferably, a servo motor is fixedly connected to the top surface of the support plate directly above the threaded rod, and the outer end of the drive shaft of the servo motor is fixedly connected to the top end of the threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model uses a distilled water tank, a second small water pump, a water pumping pipe, a lower rinsing tank, and a rubber water hose to rinse away water samples. After sampling, the crossbar rises, and the bottom end of the rubber water hose, under pressure, enters the lower rinsing tank. At this time, the second small water pump draws distilled water from the distilled water tank along the water pumping pipe into the lower rinsing tank. Then, the first small water pump draws water again, which draws the distilled water into the detection chamber and finally out through the drainage tank. In this process, the water samples are rinsed away, ensuring the isolation between different samples during continuous sampling and improving the accuracy of sampling and detection.
[0013] 2. This utility model uses an upper rinsing tank and a cleaning pipe to rinse the outside of a rubber water pipe. The cleaning pipe is located directly above the rubber water pipe. Before the distilled water in the lower rinsing tank is drawn from the rubber water pipe, a small second-stage water pump first draws distilled water into the upper rinsing tank. Then, the distilled water in the upper rinsing tank is discharged along the cleaning pipe to clean the rubber water pipe below. The cleaning water flows along the surface of the rubber water pipe into the lower rinsing tank and leaves through the drain pipe, thus ensuring the cleanliness of the outside of the rubber water pipe and minimizing the impact of water samples adhering to the outside of the rubber water pipe on the cleaning process, thereby improving the efficiency and purity of the cleaning.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0019] Example 1: A multi-channel continuous detection device for microorganisms in water, see [link to example]. Figures 1 to 3 The system includes a support plate 1, a crossbar 5, a drainage trough 7, and a distilled water tank 10. A vertical lifting groove 2 is formed on the side wall of the support plate 1. A threaded rod 3 is rotatably connected to the inner side of the lifting groove 2. The threaded rod 3 passes through a threaded block 4 and is threadedly connected to the threaded block 4. The outer side wall of the threaded block 4 is fixedly connected to one end of the crossbar 5. Several detection chambers 6 are evenly distributed on the inner side of the crossbar 5. A small water pump 9 is fixedly connected to the top of the crossbar 5 directly above the detection chambers 6. The outlet of the small water pump 9 is connected to the detection chambers. The interior of the chamber 6 is interconnected. The inlet of the first small water pump 9 is connected to a metal water pipe 901. The lower end of the metal water pipe 901 is connected to a rubber water pipe 902, and the rubber water pipe 902 is connected to the metal water pipe 901. The rubber water pipe 902 can easily recover its original shape when squeezed during the lifting and lowering process. During the lifting and lowering process, it is continuously squeezed by the lower flushing tank 14 and rebounds, so that the tap water in the tap water channel 16 can be sampled and the distilled water in the lower flushing tank 14 can be extracted and cleaned.
[0020] Meanwhile, an upper rinsing tank 13 is fixedly connected to the surface of the support plate 1 on one side of the lifting tank 2. Several cleaning pipes 131 are evenly distributed at the bottom of the upper rinsing tank 13. A lower rinsing tank 14 is fixedly connected to the surface of the support plate 1 directly below the upper rinsing tank 13. A second small water pump 11 is fixedly connected to the top of the distilled water tank 10. The outlet of the second small water pump 11 is fixedly connected to one end of the water pump pipe 12 and communicates with it. Two branches at the other end of the water pump pipe 12 pass through the surface of the support plate 1 and are located directly above the upper rinsing tank 13 and the lower rinsing tank 14 near the end of the support plate 1, respectively. A second electrically controlled valve 121 is sealed at the connection between the water pump pipe 12 and the support plate 1. The second electrically controlled valve 121 can control the opening and closing of the two branches of the water pumping pipe 12, thereby controlling the water intake of the upper rinsing tank 13 and the lower rinsing tank 14. The second small water pump 11 pumps distilled water from the distilled water tank 10 along the water pumping pipe 12 into the lower rinsing tank 14. At this time, the first small water pump 9 pumps water again, which will pump the distilled water into the detection chamber 6 and finally out through the drain trough 7. In this process, the water samples will be washed away, ensuring the isolation between different samples during continuous sampling. The distilled water in the upper rinsing tank 13 is discharged along the cleaning pipe 131 to clean the rubber water pipe 902 below, thereby ensuring the cleanliness of the outside of the rubber water pipe 902.
[0021] For details, see Figure 1 and Figure 2 A water quality analyzer 8 is vertically inserted into the top of the support plate 1 on one side of the No. 1 small water pump 9. The bottom of the water quality analyzer 8 is located at the bottom of the inner chamber 6. It can be pulled out directly when maintenance or replacement is needed, and the installation is very quick and convenient.
[0022] It should be noted that the water quality analyzer 8 is a well-known device that can be purchased directly from the market. We are only using it here and have not made any structural or functional improvements to it, so we will not go into details here.
[0023] Further, see Figure 2 and Figure 3 A drainage trough 7 is fixedly connected to the bottom of the crossbar 5. A first electrically controlled valve 701 is sealed between the detection chamber 6 and the drainage trough 7, and the detection chamber 6 is connected to the drainage trough 7. The first electrically controlled valve 701 is closed when water body testing is performed to ensure that the water sample in the detection chamber 6 can remain. After the test is completed, it is opened to drain the sample. During cleaning, it is closed first to allow distilled water to rinse the inner wall of the detection chamber 6, and then opened to drain the distilled water.
[0024] It is worth noting that, see Figure 2A servo motor 301 is fixedly connected to the top surface of the support plate 1 directly above the threaded rod 3. The outer end of the drive shaft of the servo motor 301 is fixedly connected to the top of the threaded rod 3. After the servo motor 301 is started, it drives the threaded rod 3 to rotate, thereby driving the crossbar 5 to rise and fall, so that the whole device can perform sampling and rinsing cycles.
[0025] It is worth noting that, see Figure 1 and Figure 3 A drain pipe 15 is provided at the bottom of the lower rinsing tank 14 away from the support plate 1. A No. 3 electric control valve 151 is sealed at the connection between the drain pipe 15 and the lower rinsing tank 14. The No. 3 electric control valve 151 is opened when the upper rinsing tank 13 rinses the outer wall of the rubber water pipe 902, so that the rinse distilled water is discharged along the drain pipe 15. Then, when rinsing the lower rinsing tank 14, it remains open until the lower rinsing tank 14 is clean, and then it is closed to store water, so that the rubber water pipe 902 can pump water to rinse the detection chamber 6.
[0026] It is worth mentioning that, see Figure 3 The bottom end of the cleaning pipe 131 is located directly above the surface of the rubber water pipe 902, so that the outer surface of the rubber water pipe 902 can be rinsed, and the rinsing area is higher than the depth of the rubber water pipe 902 extending into the tap water channel 16, ensuring that all the parts soaked in tap water in the tap water channel 16 are rinsed.
[0027] Working principle: When sampling and testing are required, the servo motor 301 drives the threaded rod 3 to rotate, causing the threaded block 4 to descend along with the crossbar 5, so that the bottom end of the rubber water pipe 902 contacts the tap water flowing in the tap water channel 16 below. Then, the first small water pump 9 starts, drawing the tap water along the rubber water pipe 902 and the metal water pipe 901 into the testing chamber 6, where it is then tested by the water quality analyzer 8. After testing, the first electrically controlled valve 701 opens, guiding the sample tap water in the testing chamber 6 into the drainage trough 7 for unified discharge. The water is then discharged through the distilled water tank 10 and the second small water pump. Pump 11, water pipe 12, lower rinsing tank 14, and rubber water pipe 902 can rinse away water samples. After sampling, the crossbar 5 rises, and the bottom end of the rubber water pipe 902, under pressure, enters the lower rinsing tank 14. At this time, the second small water pump 11 draws distilled water from the distilled water tank 10 along the water pipe 12 into the lower rinsing tank 14. Then, the first small water pump 9 draws water, which is then drawn into the detection chamber 6 and finally exits through the drain trough 7. In this process, the water samples are rinsed away, ensuring that different samples are rinsed away during continuous sampling. The isolation improves the accuracy of sampling and detection. Simultaneously, the outer side of the rubber water pipe 902 can be rinsed through the upper rinsing tank 13 and the cleaning pipe 131. The cleaning pipe 131 is located directly above the rubber water pipe 902. Before the rubber water pipe 902 draws distilled water from the lower rinsing tank 14, the second small water pump 11 first draws distilled water into the upper rinsing tank 13. Then, the distilled water in the upper rinsing tank 13 is discharged along the cleaning pipe 131 to clean the lower rubber water pipe 902. The cleaning water then flows along the surface of the rubber water pipe 902 into the lower rinsing tank 14 and... The water sample leaves through the drain pipe 15, thus ensuring the cleanliness of the outside of the rubber water pipe 902 and minimizing the impact of water samples on the outside of the rubber water pipe 902 on the cleaning process, thereby improving the cleaning efficiency and purity. After the rubber water pipe 902 is cleaned by the upper rinsing tank 13 and the cleaning pipe 131, the lower rinsing tank 14 needs to be rinsed before water can be stored. At this time, the second small water pump 11 pumps water into the lower rinsing tank 14, cleans the lower rinsing tank 14 in the flow, and leaves through the drain pipe 15, thus preventing water samples from remaining in the lower rinsing tank 14.
