Description

Technical Field

[0001] This utility model relates to the field of sample distribution mechanism technology, specifically a quantitative sample distribution mechanism for water quality testing with a sterilization mechanism. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural waters, as well as various types of industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is some toxic substances, such as phenols, cyanides, arsenic, lead, chromium, cadmium, mercury, and organochlorine pesticides.

[0003] In most cases, when testing water quality, staff will divide the water source sample into equal portions and test and record each portion. However, this method has some inconveniences and room for improvement. For example, after use, the sample tubes usually need to be sterilized because the water source has mixed components. This is to prevent the experimental results from being deviated due to impurities during subsequent use. However, the existing sterilization process only disinfects and cleans the sample tubes, and there is still a possibility that impurities from the water source may remain inside the sample tubes due to inadequate cleaning, thus affecting the subsequent experimental results. Therefore, the method does not have the function of enhancing sterilization.

[0004] Now, a novel quantitative sampling mechanism for water quality testing with a sterilization system is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative sampling mechanism for water quality testing with a sterilization mechanism, so as to solve the problem mentioned in the background art that it does not have the function of enhancing sterilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative sampling mechanism for water quality testing with a sterilization mechanism, comprising a test platform, a lead screw fixedly connected to the left side of the top of the test platform, a sliding sleeve movably connected to the outside of the lead screw, a sample plate fixedly connected to the right side of the sliding sleeve, a water pump disposed on the right side of the top of the test platform, a transmission pipe inserted into the left side of the water pump, three sets of insertion tubes fixedly connected to the top of the transmission pipe, an inlet pipe inserted into the right side of the water pump, and a box-shaped component for enhanced sterilization disposed above the test platform.

[0007] The box-shaped assembly includes a heating box, which is fixedly connected to the outside of the insertion tube. An air inlet is inserted into the left side of the heating box, and an outer cover is fixedly connected to the left side of the air inlet. A fan and an electric heating tube are respectively arranged inside the outer cover. A fixing sleeve is fixedly connected to the top of the heating box, and a liquid outlet pipe is arranged inside the fixing sleeve. Multiple sets of spray holes are fixedly connected to the left and right sides of the liquid outlet pipe.

[0008] As a further technical solution of this utility model, the top end of the insertion tube is connected to the bottom end of the heating box and extends into the interior of the heating box, the vertical center line of the liquid outlet tube coincides with that of the insertion tube, and the shape and size of the inside of the fixing sleeve are adapted to the shape and size of the outside of the liquid outlet tube.

[0009] As a further technical solution of this utility model, there is a distance between the insertion tube and the air inlet, and the left side of the air inlet is connected to the right side of the outer casing and extends into the interior of the outer casing.

[0010] As a further technical solution of this utility model, the horizontal center lines of the air inlet, the outer casing and the heating box coincide, the nozzles are arranged at equal intervals, and the insertion tube and the liquid outlet tube are connected.

[0011] As a further technical solution of this utility model, a side plate is welded to the left side of the test bench, a motor is provided at the top of the side plate, a threaded rod is movably connected to the top of the motor, an inner rotating rod is provided inside the threaded rod, a connecting sleeve is threadedly connected to the outside of the threaded rod, and a connecting rod is fixedly connected to the left side of the connecting sleeve.

[0012] As a further technical solution of this utility model, the bottom end of the inner rotating rod is connected to the output end of the motor, the shape and size of the outer part of the threaded rod are adapted to the shape and size of the inner part of the connecting sleeve, and the right side of the connecting rod is fixedly connected to the left side of the sliding sleeve.

[0013] As a further technical solution of this utility model, the bottom end of the sample is provided with three sets of first threaded openings, the internal threads of the first threaded openings are connected to threaded heads, the bottom end of the threaded heads is fixedly connected to a sample tube body, the bottom end of the sample tube body is movably connected to a fixing plug, and a numbered sleeve is sleeved on the outside of the sample tube body.

[0014] As a further technical solution of this utility model, the shape and size of the inside of the three sets of first threaded openings are adapted to the shape and size of the outside of the threaded head, the vertical center lines of the sample tube body, the fixing plug and the numbering sleeve coincide, the numbering sleeve is made of silicone material, and the fixing plug and the sample tube body are tightly fitted.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the quantitative sampling mechanism for water quality testing with a sterilization mechanism not only realizes the function of enhanced sterilization, but also realizes the function of height adjustment, and also realizes the function of classification and disassembly.

[0016] The sample tube is fixedly installed inside the first threaded port at the bottom of the sliding sleeve, with a heating box, air inlet, outer casing, fan, electric heating tube, fixing sleeve, liquid outlet tube, and spray holes. The sterilization solution enters from the inlet tube on the right side of the water pump and is transported by the water pump to the transmission tube on the left side. Because the insert tube extends from the inside of the fixing sleeve to the liquid outlet tube at the top of the sample tube, the sterilization solution inside the transmission tube is input into the liquid outlet tube through the insert tube. Then, the sterilization solution is evenly sprayed into the sample tube through the spray holes on both sides of the liquid outlet tube to sterilize the inside of the sample tube. At the same time, the fan inside the outer casing is turned on and the electric heating tube is heated. Because the left and right sides of the air inlet are connected to the outer casing and the heating box respectively, the heated high-temperature gas enters the interior of the heating box through the air inlet and heats the sterilization solution transported upward inside the insert tube. Ultimately, the sterilization effect inside the sample tube is further enhanced, the internal sterilization efficiency of the sample tube is improved, the high-temperature sterilization effect is better, and the function of enhanced sterilization is realized.

[0017] Equipped with a side plate, motor, threaded rod, inner rotating rod, connecting sleeve, and connecting rod, when monitoring the water source stored inside the sample tube is required, the motor at the top of the side plate is turned on, causing the inner rotating rod connected to the motor output to rotate. Simultaneously, the threaded rod fixedly connected to the outside of the inner rotating rod rotates synchronously, causing the connecting sleeve connected to the threaded rod to rotate synchronously. This causes the connecting rod on the right side of the connecting sleeve to drive the sliding sleeve connected to its right side to move up and down outside the screw, ultimately allowing the sliding sleeve to move the sample plate and sample tube upwards to detect the water source inside the sample tube. After the sample tube is used, the sliding sleeve drives the sample plate downwards until the liquid outlet tube is connected to the inside of the sample tube for sterilization. The use and sterilization processes of the sample tube are separated and do not interfere with each other, making the quantitative sample dispensing mechanism more flexible and enabling height adjustment.

[0018] By configuring a first threaded opening, a threaded head, a sample tube body, a fixing plug, and a numbered sleeve, the threaded head at the top of the sample tube body is disengaged from the three sets of first threaded openings at the bottom of the sample plate, and the test water source inside the sample tube body is replaced. This simplifies the disassembly and replacement of the sample tube body. The fixing plug is inserted into the bottom of the sample tube body. When sterilization of the sample tube body is required, the fixing plug is removed from the bottom of the sample tube body and the outlet tube is connected to the inside of the sample tube body. After sterilization, the fixing plug is reinserted into the bottom of the sample tube body to facilitate continued testing of the internal water source. The numbered sleeve makes the classification of the sample tube body clearer and prevents confusion during the test. The sample tube bodies inside the three sets of first threaded openings can be filled with different doses of water source for simultaneous experimentation, resulting in better quantitative water source dispensing and achieving the function of categorized disassembly and assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4A quantitative sampling mechanism for water quality testing with a sterilization mechanism includes a test bench 1. A lead screw 2 is fixedly connected to the left side of the top of the test bench 1. A sliding sleeve 3 is movably connected to the outside of the lead screw 2. A template 4 is fixedly connected to the right side of the sliding sleeve 3. A water pump 7 is provided on the right side of the top of the test bench 1. A transmission pipe 5 is inserted into the left side of the water pump 7. Three sets of insertion pipes 6 are fixedly connected to the top of the transmission pipe 5. An inlet pipe 8 is inserted into the right side of the water pump 7. A box-shaped component that can enhance sterilization is provided above the test bench 1.

[0026] Please see Figure 1-4 A quantitative sampling mechanism for water quality testing with a sterilization mechanism also includes a box-shaped component. The box-shaped component includes a heating box 9, which is fixedly connected to the outside of the insertion tube 6. An air inlet 10 is inserted into the left side of the heating box 9, and an outer cover 11 is fixedly connected to the left side of the air inlet 10. A fan 12 and an electric heating tube 13 are respectively arranged inside the outer cover 11. A fixing sleeve 14 is fixedly connected to the top of the heating box 9, and an outlet pipe 15 is arranged inside the fixing sleeve 14. Multiple sets of spray holes 16 are fixedly connected to the left and right sides of the outlet pipe 15.

[0027] The top end of the insertion tube 6 is connected to the bottom end of the heating box 9 and extends into the interior of the heating box 9. The vertical center line of the liquid outlet tube 15 coincides with that of the insertion tube 6. The shape and size inside the fixing sleeve 14 are adapted to the shape and size outside the liquid outlet tube 15. There is a distance between the insertion tube 6 and the air inlet 10. The left side of the air inlet 10 is connected to the right side of the outer cover 11 and extends into the interior of the outer cover 11. The horizontal center lines of the air inlet 10, the outer cover 11, and the heating box 9 coincide. The nozzles 16 are arranged at equal intervals. The insertion tube 6 and the liquid outlet tube 15 are connected.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the sample tube body 25 is fixedly installed inside the first threaded port 23 at the bottom of the sliding sleeve 3. After the sterilizing solution enters from the inlet pipe 8 on the right side of the water pump 7, it is transported by the water pump 7 to the inside of the transfer pipe 5 on the left side. Because the insertion tube 6 is connected to the outlet pipe 15 inside the sample tube body 25 that extends from the inside of the fixed sleeve 14, the sterilizing solution inside the transfer pipe 5 is input into the outlet pipe 15 through the insertion tube 6. Then, the sterilizing solution is evenly sprayed into the inside of the sample tube body 25 by the spray holes 16 on both sides of the outlet pipe 15, so as to facilitate sterilization. The sample tube 25 is sterilized inside, and the fan 12 inside the outer casing 11 is turned on to heat the heating tube 13. Since the left and right sides of the air inlet 10 are connected to the outer casing 11 and the heating box 9 respectively, the heated high-temperature gas enters the interior of the heating box 9 through the air inlet 10 and heats the sterilization liquid transported upward inside the insertion tube 6 at high temperature. This further enhances the sterilization effect inside the sample tube 25, improves the internal sterilization efficiency of the sample tube 25, and achieves better high-temperature sterilization.

[0029] A side plate 17 is welded to the left side of the test bench 1. A motor 18 is installed at the top of the side plate 17. A threaded rod 19 is movably connected to the top of the motor 18. An inner rotating rod 20 is installed inside the threaded rod 19. A connecting sleeve 21 is threadedly connected to the outside of the threaded rod 19. A connecting rod 22 is fixedly connected to the left side of the connecting sleeve 21. The bottom end of the inner rotating rod 20 is connected to the output end of the motor 18. The external shape and size of the threaded rod 19 are compatible with the internal shape and size of the connecting sleeve 21. The right side of the connecting rod 22 is fixedly connected to the left side of the sliding sleeve 3.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, when it is necessary to monitor the water source stored inside the sample tube 25, the motor 18 at the top of the side plate 17 is turned on, causing the inner rotating rod 20 connected to the output end of the motor 18 to rotate. At the same time, the threaded rod 19 fixedly connected to the outside of the inner rotating rod 20 rotates synchronously, causing the connecting sleeve 21 connected to the threaded rod 19 to rotate synchronously. This causes the connecting rod 22 on the right side of the connecting sleeve 21 to drive the sliding sleeve 3 connected to its right side to move up and down outside the screw 2. Finally, the sliding sleeve 3 can drive the sample plate 4 and the sample tube 25 to move upward, thereby detecting the water source inside the sample tube 25. After the sample tube 25 is used, the sliding sleeve 3 drives the sample plate 4 to move downward until the liquid outlet tube 15 is connected to the inside of the sample tube 25, so as to sterilize the used test tube. The use and sterilization processes of the test tube are separated and do not interfere with each other, making the quantitative sample dispensing mechanism more flexible.

[0031] The bottom of the sample 4 is provided with three sets of first threaded openings 23. The internal threads of the first threaded openings 23 are connected to threaded heads 24. The bottom of the threaded heads 24 is fixedly connected to the sample tube body 25. The bottom of the sample tube body 25 is movably connected to a fixing plug 26. The outside of the sample tube body 25 is fitted with a numbered sleeve 27. The internal shape and size of the three sets of first threaded openings 23 are matched with the external shape and size of the threaded heads 24. The vertical center lines of the sample tube body 25, the fixing plug 26 and the numbered sleeve 27 coincide. The numbered sleeve 27 is made of silicone. The fixing plug 26 and the sample tube body 25 fit tightly together.

[0032] Specifically, such as Figure 1 and Figure 4As shown, the threaded head 24 at the top of the sample tube 25 is disengaged from the three sets of first threaded ports 23 at the bottom of the sample plate 4, and the test water source inside the sample tube 25 is replaced, making the disassembly and replacement of the sample tube 25 simpler. The fixing plug 26 is inserted into the bottom of the sample tube 25. When it is necessary to sterilize the inside of the sample tube 25, the fixing plug 26 is removed from the bottom of the sample tube 25 and the outlet tube 15 is connected into the inside of the sample tube 25. After the sterilization is completed, the fixing plug 26 is reinserted into the bottom of the sample tube 25 to facilitate the continued testing of the internal water source. The numbering sleeve 27 makes the classification of the sample tubes 25 clearer and prevents confusion during the test. The sample tubes 25 inside the three sets of first threaded ports 23 can be filled with different doses of water source for simultaneous experimentation, making the quantitative filling effect of the water source better.

[0033] Working principle: In use, the sample tube 25 is first fixedly installed inside the first threaded port 23 at the bottom of the sliding sleeve 3. The sterilization solution enters from the inlet pipe 8 on the right side of the water pump 7 and is transported by the water pump 7 to the inside of the transfer pipe 5 on the left side. Because the insertion tube 6 is connected to the outlet pipe 15 inside the sample tube 25 extending from the inside of the fixed sleeve 14, the sterilization solution inside the transfer pipe 5 is input into the outlet pipe 15 through the insertion tube 6. Then, the sterilization solution is evenly sprayed into the inside of the sample tube 25 by the spray holes 16 on both sides of the outlet pipe 15 to sterilize the inside of the sample tube 25. At the same time, the fan 12 inside the outer cover 11 is turned on and the electric heating tube 13 is heated. The outer left and right sides are connected to the outer casing 11 and the heating box 9, respectively. The heated high-temperature gas enters the interior of the heating box 9 through the air inlet 10 and heats the sterilization liquid transported upward inside the insertion tube 6, thereby further enhancing the sterilization effect inside the sample tube 25 and improving the internal sterilization efficiency of the sample tube 25. The high-temperature sterilization effect is better. When it is necessary to monitor the water source stored inside the sample tube 25, the motor 18 at the top of the side plate 17 is turned on, causing the inner rotating rod 20 connected to the output end of the motor 18 to rotate. At the same time, the threaded rod 19 fixedly connected to the outside of the inner rotating rod 20 rotates synchronously, causing the connecting sleeve 21 threadedly connected to the outside of the threaded rod 19 to rotate synchronously. The movement causes the connecting rod 22 on the right side of the connecting sleeve 21 to move the sliding sleeve 3 connected to it up and down outside the screw 2. Ultimately, the sliding sleeve 3 moves the sample plate 4 and sample tube 25 upwards to detect the water inside the sample tube 25. After the sample tube 25 is used, the sliding sleeve 3 moves the sample plate 4 downwards until the outlet tube 15 is connected to the inside of the sample tube 25 for sterilization. The use and sterilization processes of the test tubes are separate and do not interfere with each other, making the quantitative sampling mechanism more flexible. The threaded head 24 at the top of the sample tube 25 is disengaged from the three sets of first threaded openings 23 at the bottom of the sample plate 4, and the detection device inside the sample tube 25 is replaced. The water source makes the disassembly and replacement of the sample tube 25 simpler. The fixing plug 26 is inserted into the bottom of the sample tube 25. When it is necessary to sterilize the inside of the sample tube 25, the fixing plug 26 is removed from the bottom of the sample tube 25 and the liquid outlet tube 15 is connected to the inside of the sample tube 25. After the sterilization is completed, the fixing plug 26 is reinserted into the bottom of the sample tube 25 to facilitate the continued testing of the water source inside. The numbering sleeve 27 makes the classification of the sample tubes 25 clearer and prevents confusion during the test. The sample tubes 25 inside the three sets of first threaded ports 23 can be filled with different doses of water source for simultaneous experimentation, making the quantitative filling effect of water source better.
