DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will combine the drawings of the present application and embodiments to make further detailed description of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Figures 1-4 The purpose, technical scheme and advantages of the present application will be further described in detail in combination with the drawings of the present application and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0038] An embodiment of the present application discloses a water pollution sensing device. Referring to Figure 1 , the water pollution sensing device comprises a controller 110, a sample collector 120, a reagent storage device 130, a waste liquid treatment device 140 and a water quality detector 150, and the controller 110 is signal connected with the water quality detector 150.

[0039] The sample collector 120 is used to collect water samples at a sampling site. In an example, the collection depth of the sample collector 120 can be adjusted, so that the collection depth of the sample collector 120 can be adjusted according to the actual monitoring needs. In actual implementation, the number of sample collectors 120 can be one, or can be more than two. In the case of more than two sample collectors 120, different sample collectors 120 are arranged at different collection positions of the target water area, so that the collected samples can better reflect the actual situation of the target water area.

[0040] The reagent storage device 130 is used to store reagents required in the water quality detection process, such as zinc sulfate, potassium sodium tartrate solution, etc. In an example, the reagent storage device 130 comprises at least one reagent tank, and different reagent tanks can be used to store different types of reagents.

[0041] The water quality detector 150 comprises a sample inlet 151, a reagent inlet 152, and a waste liquid outlet 153. The sample collector 120 is connected to the sample inlet 151 through a first pipeline, the reagent storage device 130 is connected to the reagent inlet 152 through a second pipeline, and the waste liquid treatment device 140 is connected to the waste liquid outlet 153 through a third pipeline.

[0042] The water quality detector 150 is configured to obtain the water sample collected by the sample collector 120 through the first pipeline, obtain the reagent stored in the reagent storage device 130 through the second pipeline, discharge the waste liquid to the waste liquid treatment device 140 through the third pipeline, and transmit the detection data obtained by detecting the water sample to the controller 110 based on the communication connection between the water quality detector 150 and the controller 110.

[0043] In one example, when the water quality is detected by the water quality detector 150, the sample collected by the sample collector 120 is obtained first, then the reagent stored in the reagent storage device 130 is obtained, the reagent is mixed with the sample, the mixed liquid is detected, and then the mixed liquid is discharged into the waste liquid treatment device 140.

[0044] Further, since the reagent is usually corrosive, the second pipeline can be a corrosion-resistant pipeline, which can help to avoid corrosion of the second pipeline during use, thereby helping to improve the service life of the water pollution perception device. In one example, the inner wall of the corrosion-resistant pipeline comprises a coating with a corrosion-resistant function, such as a polytetrafluoroethylene coating, a polyethylene coating, etc. In actual implementation, the corrosion-resistant pipeline can also be made of a corrosion-resistant material as long as it has a corrosion-resistant function.

[0045] The waste liquid treatment device 140 is configured to treat the waste liquid generated in the detection process. Specifically, the waste liquid treatment device 140 can be a waste liquid collection tank for collecting waste liquid, or can also be a waste liquid filtering device for filtering waste liquid, such as a device for neutralizing and precipitating waste liquid. The implementation of the waste liquid treatment device 140 is not limited in the embodiment.

[0046] The controller 110 is configured to control the water quality detection process. In one example, the controller 110 is configured to control the operation of the water quality detector 150 and obtain the detection result generated by the water quality detector 150. In one example, the controller 110 comprises a storage device for storing the received detection result. In another example, the water pollution perception device further comprises a communication module, and the controller 110 is in communication connection with a background server through the communication module, so that the controller 110 can send the received data to the background server for comprehensive research and judgment of the water pollution state by combining different dimensions of factors through the background server.

[0047] In one example, the waste liquid outlet 153 is provided with an electromagnetic valve connected with the controller 110 in signal, for opening and closing under the control of the controller 110, so that the opening and closing of the waste liquid outlet 153 can be controlled by the controller 110, thereby realizing the control of the waste liquid discharge.

[0048] In some embodiments, the water pollution sensing device further comprises a flow rate sensor connected with the controller 110 in signal, for collecting the flow rate of the water quality monitoring area and sending to the controller 110. In one example, the flow rate sensor is arranged near the sample collector 120. Since the water flow rate can affect the quality of the collected water sample, and thus affect the result of water pollution sensing, the flow rate sensor arranged in the water pollution sensing device can collect the flow rate synchronously during the water pollution sensing process, thereby helping to analyze and process the flow rate and detection result later.

[0049] In some embodiments, the water pollution sensing device further comprises a positioning device, so that the latitude and longitude coordinates of the device can be located. In this way, when the device carries out detection, the information uploaded to the cloud server includes the detection time, latitude and longitude coordinates, and water pollution related information. Thus, the flow path of the device can be accurately known when visualized.

[0050] In actual implementation, the water pollution sensing device can further comprise other devices, such as a temperature monitoring device, and the present embodiment does not limit the composition of the water pollution sensing device.

[0051] The implementation principle of the water pollution sensing device according to the embodiment of the present application is as follows: the water pollution sensing device comprises a controller, a sample collector, a reagent storage device, a waste liquid treatment device and a water quality detector, the controller is connected with the water quality detector in signal; the water quality detector comprises a sample inlet, a reagent inlet and a waste liquid outlet; the sample collector is connected with the sample inlet through a first pipeline, the reagent storage device is connected with the reagent inlet through a second pipeline, and the waste liquid treatment device is connected with the waste liquid outlet through a third pipeline; the water quality detector is used to obtain the water sample collected by the sample collector through the first pipeline, obtain the reagent stored in the reagent storage device through the second pipeline, discharge waste liquid to the waste liquid treatment device through the third pipeline, and transmit the detection data obtained by detecting the water sample to the controller based on the communication connection between the controller. By adopting the above technical solution, since the water pollution sensing device comprises the reagent storage device, and the reagent storage device is connected with the water quality detector through the third pipeline, it can help to use the reagent to process the water sample during water quality detection, thereby helping to realize some complex detection, and thus better meeting the diversified water pollution monitoring demand.

[0052] In addition, the waste liquid treatment device is connected with the waste liquid outlet of the water quality detector to receive the waste liquid generated in the detection process, so as to reduce the influence of the detection process on the environment, and to meet the green and environmental protection requirements.

[0053] In some embodiments, referring to Figure 2 , the first peristaltic pump 161 is arranged on the first pipeline, and the second peristaltic pump 162 is arranged on the second pipeline. The controller 110 is signal connected with the first peristaltic pump 161 and the second peristaltic pump 162 respectively to control the operation of the first peristaltic pump 161 and the second peristaltic pump 162.

[0054] Specifically, the first peristaltic pump 161 is used to draw the sample in the sample collector 120 into the water quality detector 150 through the first pipeline. The second peristaltic pump 162 is used to draw the reagent in the reagent storage device 130 into the water quality detector 150 through the second pipeline.

[0055] In the above technical solution, the peristaltic pump is used as the power for sample and reagent transmission, which can avoid cross contamination of the sample and corrosion of the pump body metal parts by the reagent, thereby improving the safety of the sample and reagent transmission process.

[0056] Further, the first peristaltic pump 161 and the second peristaltic pump 162 are driven by a stepping motor. Since the stepping motor can provide precise speed and position control, the amount of sample and reagent drawn can be accurately controlled, thereby improving the accuracy of the detection result. In actual implementation, the first peristaltic pump 161 and the second peristaltic pump 162 can also be controlled by a servo motor or a direct current motor.

[0057] In some embodiments, referring to Figure 3 , the waste liquid treatment device includes a reaction container 154 and a sensing assembly 155 arranged in the reaction container.

[0058] Correspondingly, the sample inlet 151, the reagent inlet 152 and the waste liquid outlet 153 are arranged on the reaction container 154. The sample inlet 151 is used to introduce the sample into the reaction container 154, the reagent inlet 152 is used to introduce the reagent into the reaction container 154, and the waste liquid outlet 153 is used to guide the waste liquid in the reaction container 154 out. In this way, the sample and the reagent can be mixed and reacted in the reaction container 154. Further, the reaction container 154 is provided with a stirring assembly to enable the sample and the reagent to be fully mixed and reacted.

[0059] The sensing assembly 155 is configured to collect the chemical properties of the liquid in the reaction container 154. Since the sample and the reagent can be mixed and reacted in the reaction container 154, and the sensing assembly 155 can collect the chemical properties of the liquid in the reaction container 154, the reaction result of the sample and the reagent can be collected by the sensing assembly 155, so as to realize the collection of the detection result. In actual implementation, the sensing assembly 155 includes at least one of a turbidity sensor, a dissolved oxygen sensor, a conductivity sensor, an ammonia nitrogen sensor, and the like.

[0060] Further, the waste liquid outlet is located at the bottom of the reaction container 154, and the height difference between the sample inlet 151 and the reagent inlet 152 and the waste liquid outlet 153 is greater than two-thirds of the height of the reaction container 154. Therefore, after the sample and the reagent flow into the reaction container 154 from the sample inlet 151 and the reagent inlet 152 located above the reaction container 154, they are mixed and reacted at the bottom of the reaction container 154, and finally flow out from the bottom of the reaction container 154. Therefore, the waste liquid and the reagent can be mixed and reacted in the reaction container 154 by taking full advantage of gravity, and then flow out as waste liquid, which can help the smooth progress of the detection process.

[0061] The embodiments of the present application also provide a water pollution monitoring system, which refers to Figure 4 The water pollution monitoring system includes a cloud server 200 and at least one water pollution sensing device 100 provided by the above-mentioned embodiments, and the water pollution sensing device 100 is in communication connection with the cloud server 200. Specifically, the water pollution sensing device 100 includes a communication module connected with the controller, and the communication module is configured to be in communication connection with the cloud server 200. In one example, the communication module is a DTU (Data Transfer Unit) transmission module. In one example, the water pollution sensing device 100 and the cloud server 200 are connected through a cellular network, such as a 4G / 5G network.

[0062] The above is only part of the embodiments of the present application, and it should be pointed out that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
