Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a water quality monitoring device with automatic monitoring and dosing. Background Technique

[0002] Water quality monitoring refers to the regular or continuous monitoring of various physical, chemical and biological parameters in water bodies to evaluate and ensure that the water quality meets specific standards and requirements, and sometimes it is necessary to add corresponding medicaments to the water bodies in a timely manner according to the monitored data to protect the water quality.

[0003] For example, a water quality monitoring and dosing device with automatic monitoring and dosing, the authorized announcement number is: CN220270886U. Fill the inside of the sampling box with water, then start the motor to drive the screw to rotate, so that the clamping plate on the screw drives the telescopic tube fixedly connected inside it to move up and down, and sample the water at the upper, middle and lower positions inside the sampling box. Then start the first water pump. When sampling the water above, open the first valve and close the other two valves. When sampling the water in the middle, open the second valve and close the other two valves. When sampling the water below, open the third valve and close the other two valves. After the sampled water enters the required detection box and reacts with the reagents in the box, determine the amount of medicine sent to the sampling box according to the data shown by the reagents, and finally start the second water pump to carry out the medicine delivery process.

[0004] However, the inside of the sampling box in the prior art is a complete cavity. Therefore, the water poured into the sampling box will be mixed during the injection process, and directly performing stratified pumping and detection will affect the detection result. Although waiting for the water in the sampling box to automatically stratify and then performing stratified pumping and detection can ensure the detection result, the waiting time for stratification will affect the detection efficiency.

However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] As Figures 1-5 shown, a water quality monitoring device for automatic monitoring and dosing includes a base 1, and a sampling box 4 is provided on the base 1. Inside the sampling box 4, a plurality of layers of partition plates 20 are arranged from top to bottom, and the inside of the sampling box 4 is divided into different spaces by the plurality of layers of partition plates 20 from top to bottom. By providing the plurality of partition plates 20, it can be ensured that the sample water bodies extracted at different depths or different sampling points are stored separately without mixing. At the top edge position of the side wall of each space inside the sampling box 4, a water inlet pipe 12 is connected, and at the bottom edge position, a water outlet pipe 13 is connected. A spring rod 15 is fixedly connected inside the water outlet pipe 13, and a sealing plate 16 for blocking the inner port of the water outlet pipe 13 is fixedly connected to the telescopic end of the spring rod 15. Sample water is injected into the corresponding space through the water inlet pipe 12, and the sealing plate 16 provided in the water outlet pipe 13 plays a role in blocking the water outlet pipe 13 under the elastic support of the spring rod 15 to prevent the loss of the sample water quality in the space. When detection is required, only need to insert the telescopic pipe 19 into the water outlet pipe 13 and continuously move it to push the sealing plate 16 to move and open against the thrust of the spring rod 15, then the medicament can enter the sample water quality along the telescopic pipe 19. A sliding frame 6 is slidably connected to the outside of the base 1 near the sampling box 4. Inside the sliding frame 6, a lead screw 9 driven by a motor is rotatably connected, and a lifting block 8 threadedly connected to the lead screw 9 is slidably installed. One side of the lifting block 8 is fixedly connected with a connecting pipe 14. A telescopic pipe 19 for pushing the sealing plate 16 is slidably sleeved inside the connecting pipe 14, and a water quality detection sensor 17 is arranged inside the telescopic pipe 19. As Figure 1 shown, a plurality of water inlet pipes 12 and water outlet pipes 13 are arranged in parallel. Therefore, in actual use, the sliding frame 6 is slid to make the connecting pipe 14 located in the vertical plane where the plurality of water inlet pipes 12 are located, and the lifting block 8 is lifted and lowered by rotating the lead screw 9 inside the sliding frame 6. The connecting pipe 14 is driven by the lifting block 8 to the position of each water inlet pipe 12 or water outlet pipe 13, and the telescopic pipe 19 is moved by installing an electric telescopic rod inside the connecting pipe 14, then the telescopic pipe 19 can be sleeved on the water inlet pipe 12 or inserted into the water outlet pipe 13 and used to push the sealing plate 16 to move.

[0025] In addition: A sampling pump 5 is provided on one side of the base 1. The water inlet end of the sampling pump 5 extends into the water body, and the water outlet end is sleeved on one end of the connecting pipe 14 through a hose. An electric push rod 7 for pushing the sliding frame 6 to slide is fixedly connected to the base 1. A reflux cover 18 is fixedly connected to the upper surface of the base 1 near the sampling box 4. The side of the reflux cover 18 is hollowed out at positions equal to the height of each water inlet pipe 12, and the hollowed-out part is inserted with the telescopic pipe 19. During actual use, a known winch can be used to connect the water inlet end of the sampling pump 5 to realize the lifting of the water inlet end of the sampling pump 5 within the same sampling point, so as to obtain water body samples at different depths, or move the position of the water inlet end of the sampling pump 5 to realize the acquisition of water body samples at different sampling points. In addition, the sampling pump 5 provided can be a commonly used water pump on the market. The function of the provided reflux cover 18 is that when sampling water body samples at different depths or different positions, first adjust the position of the sliding frame 6 so that the connecting pipe 14 is aligned with the reflux cover 18, and insert the telescopic pipe 19 into the reflux cover 18 to ensure that the initial water body sample is discharged along the reflux cover 18, that is, the initial water body sample drawn can wash away the residual water body sample from the previous draw in the connecting pipe 14, the sampling pump 5 and the telescopic pipe 19, preventing the residual part of the water body sample from the previous draw from mixing with the water body sample drawn next time.

[0026] In addition: Two raw material tanks 3 and a sodium hypochlorite storage tank 2 are also provided on the base 1. A discharge pump 10 is provided at the position of the two raw material tanks 3 on the base 1, and a digital metering pump 11 is provided at the position of the sodium hypochlorite storage tank 2. Both the water inlet end and the water outlet end of the discharge pump 10 are provided with two. The two water inlet ends and the two water outlet ends are grouped in pairs. Each group specifically includes a water inlet and a water outlet. The water inlet and the water outlet of one group are respectively communicated with the two raw material tanks 3. The water inlet and the water outlet of the other group are respectively connected to one of the raw material tanks 3 and the connecting pipe 14. The number of the digital metering pumps 11 is two. The water inlet and the water outlet of one of the digital metering pumps 11 are respectively connected to the sodium hypochlorite storage tank 2 and the connecting pipe 14. The water inlet and the water outlet of the other digital metering pump 11 are respectively connected to the sodium hypochlorite storage tank 2 and the clear water tank. One end of the discharge pump 10, the sodium hypochlorite storage tank 2 communicated with the connecting pipe 14, and the bottom end of the partition plate 20 are all connected with a switching valve. In this solution, the two raw material tanks 3 provided are respectively used to store the commercial stock solution with a concentration of 10%, and for empty use. And an additional water pump can be provided for the empty raw material tank 3 to add water into it. Under the action of one of the discharge pumps 10, a part of the commercial stock solution in the other raw material tank 3 is sent into the empty raw material tank 3, and water equal to the amount of the sent commercial stock solution is added into the empty raw material tank 3 through the water pump. The raw material tank 3 uses a mechanical stirrer to mix and dilute the commercial stock solution by adding water in a ratio of 1:1 to a concentration of 5% for storage and dosing. The discharge pump 10 uses a fluoroplastic magnetic pump, which also serves to discharge the commercial liquid to the storage tank and mix after dilution. And the mixed stock solution is sent through the other discharge pump 10 along the connecting pipe 14 and the telescopic pipe 19 to the upper part of the corresponding partition plate 20 for experiments, and the amount and concentration of the poured stock solution are adjusted in real time according to the detection data of the water quality detection sensor 17. And one of the digital metering pumps 11 provided sends the sodium hypochlorite solution in the sodium hypochlorite storage tank 2 along the connecting pipe 14 and the telescopic pipe 19 into the corresponding water sample for reaction observation. When the volume and concentration of the added stock solution and the amount of the added sodium hypochlorite solution can treat the sample water quality in the sampling tank 4, the reverse rotation of the additionally installed water pump can be directly used to realize the addition of the stock solution in the raw material tank 3 and the solution in the sodium hypochlorite storage tank 2 into the water body at the sampling point by using the other digital metering pump 11.

[0027] Working principle: When the sliding frame 6 moves by using the telescopic movement of the electric push rod 7, the telescopic pipe 19 is aligned with the positions of a plurality of water inlet pipes 12. Then, when the lifting block 8 moves to the corresponding water inlet pipe 12 by using the rotation of the lead screw 9, the telescopic pipe 19 extends to be sleeved on the water inlet pipe 12. Then, the water body sample at the sampling point is sent into a partial space in the sampling box 4 communicated with the water inlet pipe 12 by using the sampling pump 5. Then, the position of the telescopic pipe 19 is adjusted. Before extracting the next sample, the telescopic pipe 19 moves to the reflux cover 18, so that the water body sample extracted in the early stage flushes the residual water body sample of the previous time in the pipeline. After flushing clean, the telescopic pipe 19 moves to the water inlet pipe 12 on the next layer to realize the collection of the re-extracted water body sample. After the water body sample extraction is completed, the telescopic pipe 19 moves to the water outlet pipe 13 and extends into the water outlet pipe 13 to push the sealing plate 16 to move and open. According to the data of the water quality detection sensor 17 in the telescopic pipe 19, appropriate medicaments are added to the water body in the sampling box 4 by using the discharging pump 10 and the digital metering pump 11, and the addition is from less to more until the concentration and volume of the added medicaments can effectively treat the water body sample in the sampling box 4. Then, according to the volume ratio of the water body sample in the sampling box 4 to the volume of the added medicaments, and according to the volume of the water body at the sampling point, the corresponding medicaments are added by using other water pumps and the digital metering pump 11.
