Description

Technical Field

[0001] This application relates to the field of water quality testing technology, and in particular to a sampling device for water quality testing in a smart water management platform. Background Technology

[0002] With socio-economic development and increased environmental awareness, water resource quality management has become increasingly important. Therefore, in order to ensure water safety and maintain ecological balance and biodiversity, water quality sampling and testing are necessary.

[0003] The traditional and common sampling method is manual sampling, in which staff carry portable instruments to collect samples on-site and then send them back to the laboratory for analysis. Although this sampling method is simple and easy to implement, it is greatly affected by human factors and is difficult to monitor in real time, which has obvious shortcomings. Utility Model Content

[0004] To address the issue of significant human error in manual sampling, this application provides a sampling device for water quality testing in a smart water management platform.

[0005] The sampling device for water quality testing in a smart water management platform provided in this application adopts the following technical solution:

[0006] A sampling device for water quality testing in a smart water management platform includes a sampling pump electrically connected to a control system. The inlet of the sampling pump is connected to a sample delivery pipe that extends into a sample water source. The outlet of the sampling pump is equipped with a control valve for controlling the outflow of sample water.

[0007] By adopting the above technical solution, during sampling, the control system starts the sampling pump, the sample delivery tube begins to extract the sample, the control valve is opened, and the sample flows through the sampling pump and control valve before being poured into the storage bottle. This fully automated intelligent sampling method enables real-time monitoring of water quality, reducing the impact of human factors.

[0008] Optionally, a flow meter is also connected between the control valve and the outlet of the sampling pump, and both the flow meter and the control valve are electrically connected to the control system.

[0009] By adopting the above technical solution, the flow meter can monitor the flow rate of the extracted sample, and thereby control the opening and closing of the control valve according to the size of the storage container.

[0010] Optionally, the top of the sample delivery tube is connected to an internally hollow mounting box, and a filter screen for inserting into the sample delivery tube is vertically slidably arranged inside the mounting box. The top of the mounting box is also provided with a first telescopic cylinder electrically connected to the control system. The piston rod of the first telescopic cylinder extends into the mounting box and is connected to the filter screen by a pull wire.

[0011] By adopting the above technical solution, the control system starts the first telescopic cylinder, and the piston rod of the first telescopic cylinder extends downward, so that the filter screen descends into the sample delivery tube under the action of gravity, thereby intercepting impurities in the sample and saving the filtration process of sample detection.

[0012] Optionally, multiple filter screens are arranged in the installation box along the direction of water flow in the sample delivery tube. The aperture of the multiple filter screens gradually decreases as they approach the sampling pump. Each filter screen is connected to the piston rod of the first telescopic cylinder by a pull wire.

[0013] By adopting the above technical solution, multiple filters work together to achieve zoned interception and filtration of impurities of different sizes in the sample, reducing the possibility of impurities of different sizes accumulating in the same place and causing blockage.

[0014] Optionally, a second telescopic cylinder electrically connected to the control system is arranged on the side of the mounting box facing away from the sampling pump. Each filter screen has a limit ring on its top, and the limit rings are arranged coaxially. The piston rod of the second telescopic cylinder extends into the mounting box and slides through and cooperates with each limit ring.

[0015] By adopting the above technical solution, when the piston rod of the second telescopic cylinder extends, it can pass through each limiting ring. Thus, when the piston rod of the first telescopic cylinder extends, only the piston rod of the second telescopic cylinder that has not passed through the filter screen corresponding to the limiting ring can enter the sample delivery tube. This achieves further control and selection of the interception of impurities in the sample.

[0016] Optionally, a vertical lifting groove is provided on the side wall of the mounting box, and the filter screen extends into the lifting groove and slides therein.

[0017] By adopting the above technical solution, the filter screen and the lifting groove slide together, thereby guiding its lifting movement.

[0018] Optionally, a magnetic plate is arranged at the bottom of the sample delivery tube relative to the mounting box to attract the filter screen magnetically.

[0019] By adopting the above technical solution, the magnetic plate has a strong magnetic attraction to the filter screen, which can overcome the friction between the filter screen and the installation box and move it into the sample delivery tube.

[0020] Optionally, the sampling tube is also connected to a cleaning tube at a position between the sampling pump and the mounting box, and the cleaning tube is connected to a water supply device.

[0021] By adopting the above technical solution, the water supply device fills the sample delivery tube with clean water through the cleaning pipe, and the clean water can flush away the impurities in the sample delivery tube.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. During sampling, the control system starts the sampling pump, the sample delivery tube begins to extract the sample, the control valve is opened, and the sample flows through the sampling pump and control valve before being poured into the storage bottle. By adopting a fully automated intelligent sampling method, real-time monitoring of water quality can be achieved, reducing the impact of human factors.

[0024] 2. The control system starts the first telescopic cylinder, and the piston rod of the first telescopic cylinder extends downward, so that the filter screen descends into the sample delivery tube under the action of gravity, thereby intercepting impurities in the sample and saving the filtration process of sample testing.

[0025] 3. Multiple filters work together to achieve zoned interception and filtration of impurities of different sizes in the sample, reducing the possibility of impurities of different sizes accumulating in the same place and causing blockage.

[0026] 4. When the piston rod of the second telescopic cylinder extends, it can pass through each limiting ring. Thus, when the piston rod of the first telescopic cylinder extends, only the piston rod of the second telescopic cylinder that has not passed through the filter screen corresponding to the limiting ring can enter the sample delivery tube. This achieves further control and selection of impurities in the sample. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a sampling device for water quality testing in a smart water management platform.

[0032] Reference Figure 1 The sampling device for water quality testing in the smart water platform includes a sampling pump 1 electrically connected to the control system. The inlet of the sampling pump 1 is connected to a sample delivery pipe 2, which extends into the sample water source.

[0033] Reference Figure 1The sampling pump 1 is also connected to an outlet pipe, on which a flow meter 4 and a control valve 3 are arranged. The flow meter 4 is located between the sampling pump 1 and the control valve 3. The control valve 3 is a solenoid valve in the prior art. Both the control valve 3 and the flow meter 4 are electrically connected to the control system.

[0034] Reference Figure 1 The control system starts sampling pump 1, and sample delivery tube 2 begins to extract the sample. Control valve 3 is opened, and the sample flows through sampling pump 1 and control valve 3, being poured into the storage bottle. Flow meter 4 monitors the sample flow rate, thereby controlling the opening and closing of control valve 3 according to the size of the storage bottle.

[0035] Reference Figure 1 and Figure 2 The top of the sample delivery tube 2 is welded and connected to an internally hollow installation box 5. A lifting groove 51 is vertically opened on the inner side wall of the installation box 5. A filter screen 6 is placed inside the installation box 5. The filter screen 6 extends into the lifting groove 51 and slides with it. The filter screen 6 is used to enter the sample delivery tube 2 to filter impurities.

[0036] Reference Figure 1 and Figure 2 Multiple filter screens 6 are arranged inside the installation box 5 along the direction of water flow in the sample delivery tube 2, and the aperture of the multiple filter screens 6 gradually decreases along the direction closer to the sampling pump 1.

[0037] The top of the outer wall of the mounting box 5 is bolted with a first telescopic cylinder 7 that is electrically connected to the control system. The piston rod of the first telescopic cylinder 7 extends into the mounting box 5, and each filter screen 6 is connected to the piston rod of the first telescopic cylinder 7 with a pull wire 8.

[0038] Reference Figure 1 and Figure 2 The control system activates the first telescopic cylinder 7, and the piston rod of the first telescopic cylinder 7 extends downward. Each filter screen 6 descends under the action of gravity, thereby entering the sample delivery tube 2 to filter the sample and reduce the possibility of impurities clogging the sampling pump 1.

[0039] Reference Figure 1 and Figure 2 The mounting box 5 is bolted to the side facing away from the sampling pump 1 with a second telescopic cylinder 9 that is electrically connected to the control system. Each filter screen 6 has a limit ring 10 welded to its top. Each limit ring 10 is coaxial with the piston rod of the second telescopic cylinder 9. The piston rod of the second telescopic cylinder 9 extends into the mounting box 5 and slides through and cooperates with each limit ring 10.

[0040] Reference Figure 1 and Figure 2When the piston rod of the second telescopic cylinder 9 extends, it can pass through each limiting ring 10. Thus, when the piston rod of the first telescopic cylinder 7 extends, only the piston rod of the second telescopic cylinder 9 that has not passed through the filter screen 6 corresponding to the limiting ring 10 can enter the sample delivery tube 2. This achieves further control and selection of the interception of impurities in the sample.

[0041] Reference Figure 1 and Figure 2 A magnetic plate 11 is attached to the bottom of the sample delivery tube 2 relative to the mounting box 5 to attract the filter screen 6 magnetically. This reduces the possibility that the filter screen 6 will not enter the sample delivery tube 2 due to the large friction between it and the side wall of the mounting box 5 after the piston rod of the first telescopic cylinder 7 extends.

[0042] Reference Figure 1 The sampling tube 2 is connected to the cleaning tube 12 between the sampling pump 1 and the mounting box 5. The cleaning tube 12 is connected to the water supply device, and a cleaning valve 13 is arranged on the cleaning tube 12.

[0043] After the sample delivery tube 2 has been used for a long time, the worker opens the cleaning valve 13, and the water supply device sends clean water into the sample delivery tube 2 through the cleaning pipe 12 to flush out the impurities in the sample delivery tube 2, thereby reducing the possibility of impurities accumulating and causing blockage.

[0044] The implementation principle of the sampling device for water quality testing of a smart water management platform according to an embodiment of this application is as follows: The control system first activates the first telescopic cylinder 7, the piston rod of the first telescopic cylinder 7 extends downward, and each filter screen 6 descends under the action of gravity and magnetic plate 11. The control system then activates the sampling pump 1, the sample delivery tube 2 begins to extract the sample, the control valve 3 is opened, the sample flows through the sampling pump 1 and the control valve 3, and is poured into the storage bottle.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
