Description

Technical Field

[0001] This utility model relates to the field of turbidity sensor calibration technology, and more specifically, to a batch calibration device for turbidity sensors. Background Technology

[0002] A turbidity sensor is an instrument used to measure the degree of light scattering or absorption by suspended particulate matter in a liquid. It quantifies the turbidity of the liquid by detecting changes in this optical property. Turbidity sensors need to be calibrated after production or after long-term use. When there are a large number of turbidity sensors, batch calibration is required.

[0003] Currently, most low turbidity sensor manufacturers need to perform multi-point data acquisition and linear fitting on each sensor in various concentration standard solutions to complete the sensor calibration work. This process results in low calibration efficiency and inconsistent performance.

[0004] Chinese patent application CN202223577676.6 discloses a batch calibration device for low turbidity sensors, including a standard solution storage tank, multiple standard solution circulation loops, a data acquisition unit, and a host computer; each standard solution circulation loop includes a peristaltic pump and a sensor flow cell. Using this utility model, the calibration of batch low turbidity sensors uses the same standard solution source, and each standard solution circulation loop circulates the solution via a peristaltic pump, resulting in high consistency of sensor calibration data; multiple low turbidity sensors can be simultaneously calibrated at once, achieving high calibration efficiency.

[0005] However, as can be seen from the accompanying drawings in the specification, this utility model involves inputting a standard solution into multiple detection cells, which allows turbidity sensors placed inside the detection cells to detect the turbidity of the standard solution. Batch calibration is achieved by comparing the turbidity value with that of the standard solution. When the turbidity sensors are removed from the detection cells and calibrated for a second inspection, it is inconvenient to clean the liquid remaining on the surface of the turbidity sensors, which can easily affect the second inspection and the effect of moving and placing them. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a batch calibration device for turbidity sensors to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a batch calibration device for turbidity sensors, including a workbench. A support plate is fixedly connected to one side of the top of the workbench, and multiple detection pools are fixedly connected to one side of the support plate. Multiple detection pools facilitate batch testing of multiple turbidity sensors, enabling batch calibration. A peristaltic pump is installed at the top of each detection pool to control the amount of standard liquid entering the pool. A control button is installed on one side of the peristaltic pump to control its opening and closing, and to control the amount of liquid passing through. A water outlet pipe is connected to the bottom of the peristaltic pump, facilitating the input of liquid into the detection pool. The bottom end of the water outlet pipe extends to the lowest point of the detection pool's inner cavity, making the liquid entering the detection pool through the water outlet pipe more stable, avoiding the generation of air bubbles, and ensuring that the measured values ​​are not affected, thus improving the accuracy of the test.

[0008] The top of the detection pool is equipped with a clamping and fixing mechanism, the front of the top of the workbench is equipped with a water collection tank, and one side of the top of the workbench is equipped with a rinsing pool. A faucet and a valve are installed on the top of the workbench corresponding to the rinsing pool. A hook is installed on the side of the support plate near the rinsing pool. The clamping and fixing mechanism facilitates the fixing of the turbidity sensor placed in the middle of the detection pool, improving the accuracy of the detection. The water collection tank facilitates the collection of dripping liquid. The rinsing pool facilitates the rinsing of the turbidity sensor surface, making cleaning convenient. The valve facilitates the control of the cleaning solution entering the rinsing pool through the faucet, facilitating rinsing. The hook facilitates the hanging of a wiping towel, making it convenient to wipe and clean the turbidity sensor after cleaning, improving the usage effect.

[0009] The workbench is equipped with a standard solution storage tank, a pressure tank, a clean water tank, and a collection tank in the middle. The pressure tank and the collection tank are respectively equipped with a second water pump and a first water pump. The second water pump inputs the standard solution from the standard solution storage tank into the pressure tank, which facilitates timely replenishment of the standard solution into the pressure tank. The pressure tank ensures that the liquid always generates a force that enters the pipeline on the peristaltic pump side. The first water pump allows the cleaning solution to be flushed out through the tap, which is convenient for cleaning the turbidity sensor and for rinsing before use.

[0010] Preferably, the input end of the second water pump is connected to the inner cavity of the standard solution storage tank, and the output end of the second water pump is connected to the inner cavity of the pressure tank. The inner cavity of the pressure tank is connected to one side of the pipes of multiple peristaltic pumps through a pipe. The second water pump facilitates the input of liquid from the standard solution storage tank into the pressure tank. The pressure tank causes the liquid to generate force to enter the pipes of the peristaltic pumps, thereby opening the peristaltic pumps and allowing the standard solution to enter the detection pool through the outlet pipe.

[0011] Preferably, the outlet pipe corresponds to the detection pool, the peristaltic pump corresponds one-to-one with the detection pool, and the control button is used to control the amount of liquid passing through the middle of the peristaltic pump. By controlling the peristaltic pump to turn on by controlling the control button, the liquid can be controlled to enter the interior of the detection pool through the outlet pipe.

[0012] Preferably, a drain pipe is connected to one side of the bottom of the detection pool, a valve is provided in the middle of the drain pipe, and one end of the drain pipe is connected to the inner cavity of the standard solution storage tank, so as to facilitate the return of the liquid inside the detection pool to the inside of the standard solution storage tank for reuse.

[0013] Preferably, the inner cavity of the rinsing pool is connected to the inner cavity of the collection tank, the input end of the first water pump is connected to the inner cavity of the clean water tank, and the output end of the first water pump is connected to the inner cavity of the faucet. The rinsing pool facilitates rinsing of the turbidity sensor after detection, and the cooperation of the first water pump and the valve facilitates the output of the cleaning solution inside the clean water tank through the faucet for easy rinsing.

[0014] Preferably, the clamping and fixing mechanism includes limiting blocks fixed on both sides of the top of the detection pool, clamping plates are symmetrically arranged on both sides of the top of the detection pool, a limiting groove is opened in the middle of the clamping plate, the limiting block is adapted to the limiting groove, and the limiting block is arranged in the middle of the limiting groove.

[0015] Preferably, a stabilizing rod is fixedly connected to the middle of the limiting groove. The stabilizing rod passes through the middle of the limiting block and is slidably connected to the limiting block. A clamping groove is provided on the opposite side of the two clamping plates. A spring is sleeved on the side of the stabilizing rod near the clamping groove. The spring pushes the limiting block, so that the two clamping plates generate a clamping force on the turbidity sensor in the middle, which facilitates the clamping and fixing of the turbidity sensor.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model firstly facilitates the rinsing of residual standard liquid on the surface of the turbidity sensor by setting up a rinsing pool, which facilitates secondary re-inspection and improves the accuracy of detection. The towel hanging on the hook facilitates wiping the surface of the turbidity sensor and improves the re-inspection effect. The water collection tank facilitates the collection and discharge of liquid dripping from the removed turbidity sensor, which improves the cleanliness of the work surface. The clamping and fixing mechanism facilitates the clamping and fixing of the turbidity sensor to be monitored, which improves the accuracy of detection.

[0018] 2. This utility model also uses a pressure tank and a second water pump to input the liquid inside the standard solution storage tank into the pressure tank. The pressure tank then evenly inputs the standard solution into the pipe connected to the peristaltic pump. When the peristaltic pump is turned on, the standard solution automatically flows out through the outlet pipe and enters the detection pool. This avoids the generation of air bubbles inside the detection pool, making the liquid flow into the detection pool more smoothly and not affecting the detection values, thus improving the accuracy of the detection.

[0019] In summary, through the interaction of the above-mentioned multiple functions, it is convenient to rinse the residual standard liquid on the surface of the turbidity sensor, facilitate secondary re-inspection, improve the accuracy of detection, and facilitate the centralized drainage of liquid dripping from the removed turbidity sensor, improving the cleanliness of the work surface and facilitating the clamping and fixing of the turbidity sensor to be monitored, thereby improving the accuracy of detection.

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.

[0026] As attached Figure 1-4The batch calibration device for turbidity sensors shown includes a workbench 1. A support plate 2 is fixedly connected to one side of the top of the workbench 1. Multiple detection cells 3 are fixedly connected to one side of the support plate 2. The multiple detection cells 3 facilitate batch testing of multiple turbidity sensors, making batch calibration convenient.

A water outlet pipe 6 is connected to the bottom of the peristaltic pump 4, which facilitates the input of liquid into the detection cells 3. The bottom end of the water outlet pipe 6 extends to the lowest point of the inner cavity of the detection cells 3, making the liquid entering the detection cells 3 through the water outlet pipe 6 more stable, avoiding the generation of air bubbles, etc., which will not affect the detection values ​​and improve the accuracy of the detection.

[0027] The top of the detection pool 3 is equipped with a clamping and fixing mechanism. A water collection tank 8 is located on the front side of the top of the workbench 1. A rinsing pool 11 is located on one side of the top of the workbench 1. A faucet 12 and a valve 13 are located on the top of the workbench 1 corresponding to the rinsing pool 11. A hook 10 is located on the side of the support plate 2 near the rinsing pool 11. A standard solution storage tank 14, a pressure tank 15, a clean water tank 16, and a collection tank 17 are located in the middle of the workbench 1. A second water pump 19 and a first water pump 18 are respectively installed on the top of the pressure tank 15 and the collection tank 17. The clamping and fixing mechanism facilitates the fixing of the turbidity sensor placed in the middle of the detection pool 3, improving the accuracy of the detection. The water collection tank 8 facilitates the collection of dripping water. Liquid collection is facilitated by rinsing tank 11 for easy rinsing of the turbidity sensor surface. Valve 13 allows for easy control of the cleaning solution entering the rinsing tank 11 via faucet 12 for convenient rinsing. Hook 10 allows for easy hanging of a wiping towel for easy cleaning of the turbidity sensor after cleaning, improving its performance. Second water pump 19 transfers standard solution from standard solution storage tank 14 into pressure tank 15 for timely replenishment. Pressure tank 15 ensures that the liquid always generates force to enter the pipe on one side of peristaltic pump 4. First water pump 18 allows the cleaning solution to be flushed out via faucet 12 for easy cleaning of the turbidity sensor and convenient rinsing.

[0028] As attached Figure 1 , 2As shown, the input end of the second water pump 19 is connected to the inner cavity of the standard solution storage tank 14, and the output end of the second water pump 19 is connected to the inner cavity of the pressure tank 15. The inner cavity of the pressure tank 15 is connected to one side of the pipes of multiple peristaltic pumps 4 through a pipe. The second water pump 19 facilitates the input of liquid from the standard solution storage tank 14 into the pressure tank 15. The pressure tank 15 generates a force that drives the liquid into the pipes of the peristaltic pumps 4, thereby turning on the peristaltic pumps 4. This allows the standard solution to be input into the detection cell 3 through the outlet pipe 6. The outlet pipe 6 corresponds to the detection cell 3, and the peristaltic pumps 4 correspond one-to-one with the detection cells 3. The control button 5 is used to control the amount of liquid passing through the middle of the peristaltic pump 4. By controlling the peristaltic pump 4 to turn on, the peristaltic pump 4 can be activated. The control liquid is input into the detection pool 3 through the water outlet pipe 6. A drain pipe is connected to one side of the bottom of the detection pool 3. A valve is installed in the middle of the drain pipe. One end of the drain pipe is connected to the inner cavity of the standard solution storage tank 14, which facilitates the return of the liquid inside the detection pool 3 to the inner cavity of the standard solution storage tank 14 for reuse. The inner cavity of the rinsing pool 11 is connected to the inner cavity of the collection tank 17. The input end of the first water pump 18 is connected to the inner cavity of the clean water tank 16. The output end of the first water pump 18 is connected to the inner cavity of the faucet 12. The rinsing pool 11 facilitates rinsing of the turbidity sensor after detection. With the cooperation of the first water pump 18 and the valve 13, the cleaning solution inside the clean water tank 16 is conveniently output through the faucet 12 for rinsing.

[0029] As attached Figure 1-4 As shown, the clamping and fixing mechanism includes limiting blocks 20 fixed on both sides of the top of the detection pool 3. Clamping plates 21 are symmetrically arranged on both sides of the top of the detection pool 3. A limiting groove 22 is opened in the middle of the clamping plate 21. The limiting block 20 is adapted to the limiting groove 22. The limiting block 20 is located in the middle of the limiting groove 22. A stabilizing rod 23 is fixedly connected to the middle of the limiting groove 22. The stabilizing rod 23 passes through the middle of the limiting block 20 and is slidably connected to the limiting block 20. A clamping groove 25 is opened on the opposite side of the two clamping plates 21. A spring 24 is sleeved on the side of the stabilizing rod 23 near the clamping groove 25. The spring 24 pushes the limiting block 20, so that the two clamping plates 21 generate a clamping force on the turbidity sensor in the middle, which facilitates the clamping and fixing of the turbidity sensor.

[0030] The working principle of this utility model is as follows: When in use, multiple turbidity sensors that need to be calibrated are placed between two clamping plates 21 and clamped and fixed by the clamping groove 25. Then, the peristaltic pump 4 is turned on by the control button 5, and the standard solution is introduced into the detection cell 3 through the water outlet pipe 6. This ensures that the amount of liquid in multiple detection cells 3 is the same and avoids the generation of air bubbles in the detection cell 3. This makes the liquid entering the detection cell 3 more stable and will not affect the detection value. By observing whether the detection value of the turbidity sensor is the same as the turbidity value of the standard solution, the turbidity sensor can be easily adjusted and calibrated.

[0031] When the turbidity sensor needs to be tested again after adjustment and calibration, the turbidity sensor is placed inside the rinsing tank 11 to rinse it, thereby cleaning the turbidity sensor to avoid residual standard liquid. It is then wiped with a towel hanging on the hook 10 for easy retesting. The water collection tank 8 is used to collect the liquid dripping from the turbidity sensor for easy centralized discharge.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
