[0001] The utility model relates to the technical field of sewage discharge detection, in particular to online detection equipment for sewage treatment wastewater discharge outlets. Background Art

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage. Since sewage contains a large amount of pollutants, direct discharge will have serious negative impacts on the environment. Therefore, sewage needs to be treated before it can be discharged.

[0003] At present, water quality testing instruments are generally installed at wastewater discharge outlets, and the detection heads of the water quality testing instruments are used to detect various indicators in sewage, so as to understand whether the sewage meets the discharge requirements. After the detection, there will be residual sewage inside the water quality testing instrument and on the surface of the detection head, which will affect the next detection result. Based on this, an online detection device for sewage treatment wastewater discharge outlets is proposed to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figures 1 to 3 As shown, the online detection device for the wastewater discharge outlet of the sewage treatment in this embodiment includes a sewage pipe 1, which is connected to an external sewage treatment device, and a discharge outlet 2 is arranged at one end of the sewage pipe 1. A blocking mechanism is installed on the side of the sewage pipe 1 near the discharge outlet 2, and the blocking mechanism is used to block the sewage pipe 1 to prevent unqualified sewage from being discharged from the sewage pipe 1. An extraction pipe 4 is installed at the upper end of the sewage pipe 1, and an extraction pump is installed on the extraction pipe 4. One end of the extraction pipe 4 extends to the inside of the sewage pipe 1, and a detection box 5 is installed at the other end of the extraction pipe 4. The internal movable A detection head 6 is installed, an equipment box 7 is installed on the upper end of the detection box 5, a discharge pipe 8 is installed on one side of the lower end of the detection box 5, and an electric valve is installed on the discharge pipe 8. The treated sewage in the sewage pipe 1 is extracted into the detection box 5 through the extraction pipe 4, and the sewage is detected by the detection head 6 to realize online detection of the sewage. After the detection, the sewage in the detection box 5 is discharged from the discharge pipe 8 to the sewage pipe 1 again. Cleaning components are installed in the detection box 5 on both sides of the detection head 6, and the cleaning components can rinse the surface of the detection head 6 after the detection.

[0022] Specifically, the blocking mechanism includes a shielding plate 301, a rotating shaft 302 and a driving motor 303. The driving motor 303 is installed on the surface of the sewage pipe 1 near the discharge port 2. The output end of the driving motor 303 is located inside the sewage pipe 1 and is installed with a rotating shaft 302. The shielding plate 301 is installed on the surface of the rotating shaft 302. The shielding plate 301 can control the on-off of the sewage pipe 1. A sealing gasket is installed on the surface of the shielding plate 301. The sealing gasket ensures the sealing performance of the shielding plate 301 when shielding. By controlling the rotation of the driving motor 303, the driving motor 303 drives the shielding plate 301 to rotate through the rotating shaft 302. The shielding plate 301 can block the sewage pipe 1, thereby controlling the on-off of the sewage pipe 1 and preventing unqualified sewage from being directly discharged from the sewage pipe 1.

[0023] Furthermore, an electric telescopic rod 10 is installed at the upper end of the detection box 5 in front of the equipment box 7. The output end of the electric telescopic rod 10 is located inside the detection box 5 and a mounting plate 11 is installed. The detection head 6 is installed at the lower end of the mounting plate 11. When the detection head 6 is moved by extending and shortening the electric telescopic rod 10, it is convenient to align the detection head 6 and the cleaning nozzle 902, thereby facilitating the cleaning of the detection head 6.

[0024] Furthermore, the cleaning component includes a cleaning tube 901 and a cleaning nozzle 902. Cleaning tubes 901 are installed at both ends of the detection head 6. One end of the cleaning tube 901 extends to the interior of the detection box 5. The cleaning tube 901 is located inside the detection box 5 and has a cleaning nozzle 902 installed at one end. The cleaning tube 901 is connected to an external liquid tank, and pure water is placed inside the liquid tank. The pure water inside the cleaning tube 901 is sprayed out from the inside of the cleaning nozzle 902 to flush the detection head 6, thereby avoiding the residual sewage from the last detection on the surface of the detection head 6 to avoid affecting the next detection result.

[0025] Furthermore, a return pipe 12 is installed below the surface of the sewage pipe 1 on one side of the shielding plate 301, and a circulation pump 13 is installed on the return pipe 12. The return pipe 12 is used to re-extract the unqualified sewage in the sewage pipe 1 into the sewage treatment equipment for re-treatment.

[0026] Furthermore, a guide block 14 is installed at the bottom of the detection box 5 , and the guide block 14 is used to guide the sewage after detection in the detection box 5 , so as to achieve complete discharge of the sewage in the detection box 5 .

[0027] The method of using this embodiment is as follows: before use, the device can be remotely controlled and the device status can be checked. When in use, the driving motor 303 drives the shielding plate 301 to rotate through the rotating shaft 302, and the shielding plate 301 shields the sewage pipe 1, so that the sewage pipe 1 is in a closed state. The sewage treated by the sewage treatment equipment enters the sewage pipe 1, and then the extraction pump on the extraction pipe 4 extracts a part of the sewage inside the sewage pipe 1 into the detection box 5. The electric telescopic rod 10 drives the detection head 6 on the mounting plate 11 to descend and contact the sewage inside the detection box 5, so as to realize online detection of the sewage. After the detection is qualified, the driving motor 303 drives the shielding plate 301 to rotate. The baffle 301 rotates to open the sewage pipe and discharge the sewage in the sewage pipe 1. When the test fails, the reflux pipe 12 flushes the sewage in the sewage pipe 1 through the circulation pump 13 and extracts it into the sewage treatment equipment for further treatment. After the test is completed, the valve on the discharge pipe 8 is opened, and the electric telescopic rod 10 is shortened to drive the detection head 6 to rise. The detection head 6 and the cleaning nozzle 902 are at the same height. The pure water in the cleaning pipe 901 flushes the detection box 5 and the detection head 6 through the cleaning nozzle 902, effectively avoiding residual sewage in the detection box 5 and the detection head 6, so as to avoid affecting the accuracy of the next detection result.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
