[0020] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0021] refer to Figures 1 to 5A sewage pipe network water quality monitoring device described in an embodiment of the present invention includes a control box 1, a control connecting plate 11 is arranged inside the control box 1, and the top of the control connecting plate 11 is connected to a sealing device 2 through an electric wire to achieve communication, and a monitoring box 12 is arranged inside the sealing device 2, and the sealing device 2 includes: a cleaning shell 21 connected to the control connecting plate 11 through an electric wire; a sealing bearing 23 rotatably mounted on the bottom of the inner wall of the cleaning shell 21; a first telescopic rod 22 fixedly mounted at the top center of the cleaning shell 21; a sealing block 24 rotatably mounted on the upper end of the sealing bearing 23, a sealing protrusion 241 is fixedly mounted on the top of the sealing block 24, and a cleaning device 3 is fixedly mounted on the top of the sealing protrusion 241, and the cleaning device 3 is used to clean the outer wall of the monitoring box 12, and a transmission device 4 is arranged inside the cleaning shell 21, and the transmission device 4 is used to seal the bottom of the sealing block 24.

[0022] It should be noted that, considering that there is generally a large amount of dirt and grease inside the drain pipe, when monitoring the sewage, there may be dirt and grease adhering to the surface of the detection components, causing errors in the detection of the components. Generally, the detection components are cleaned during maintenance and overhaul, and the monitoring box 12 cannot be cleaned in time. In the above-mentioned comparative document, when the device is used to clean it, the cleaning device itself is placed in the sewage, and flows from the inside of the cleaning device, resulting in a large amount of oil and impurities covering the surface of the cleaning device, so that it cannot be moved into the sealed device during cleaning, resulting in poor cleaning effect.

[0023] When the monitoring box 12 inside the sealing device 2 is working, Figure 4As shown, the protruding truncated cone at the upper end of the monitoring box 12 is located on the inner wall of the sealing bearing 23, and the first telescopic rod 22 is in a fully extended state. After the monitoring box 12 has been working for a period of time, the outer wall of the monitoring box 12 will be covered with a large amount of oil, impurities and floating objects. Then, the first telescopic rod 22 is started, and the first telescopic rod 22 drives the monitoring box 12 to move toward the top of the cleaning shell 21, thereby driving the monitoring box 12 to move upward along the inner wall of the sealing block 24, and the multiple sealing blocks 24 in the initial state are in contact and meshing with each other. Therefore, when the truncated cone at the upper end of the monitoring box 12 is meshed with the sealing block 24, the transmission device 4 is started, and a circular plate is arranged inside the transmission device 4, so as to seal the bottom of the cleaning shell 21, and then the sealing bearing 23 is driven by a motor to rotate, and the sealing The rotation of the sealing bearing 23 drives the sealing block 24 to rotate. A cleaning device 3 is provided at the top of the sealing block 24, thereby driving the cleaning device 3 to rotate. The cleaning device 3 can clean the outer wall of the monitoring box 12, thereby completing the work of cleaning the monitoring box 12, and the transmission device 4 seals the bottom of the cleaning shell 21, so that when cleaning the monitoring box 12, the monitoring box 12 is separated from the external environment to prevent external oil and floating objects from entering the interior of the cleaning shell 21. After cleaning, stop rotating the sealing bearing 23 and the cleaning device 3, open the transmission device 4, start the first telescopic rod 22 to drive the monitoring box 12 to move downward until the frustum at the top of the monitoring box 12 contacts the inner wall of the sealing bearing 23, then the resetting work of the monitoring box 12 is completed, and the cleaning work is completed.

[0024] refer to Figures 1 to 5 The sealing device 2 also includes: an opening 232 arranged on the sealing bearing 23, and the openings 232 are distributed in a circumferential array at the top of the sealing bearing 23; a first rotating block 233 rotatably installed inside the opening 232, and the top of the first rotating block 233 is fixedly installed at the bottom of the sealing block 24, and the outer wall of the sealing bearing 23 is provided with a plurality of first teeth 231.

[0025] It should be noted that when cleaning the monitoring box 12, it is necessary to use a motor to drive the sealing bearing 23 to rotate, thereby driving the sealing block 24 to rotate, and the rotation of the sealing block 24 drives the cleaning device 3 at the top to rotate, so as to achieve the effect of cleaning the outer wall of the monitoring box 12. If only the cleaning device 3 is used without adding water for cleaning, the oil stains inside the monitoring box 12 cannot be cleaned out, and when multiple sealing blocks 24 contact each other, a sealed cavity is formed, and water cannot enter the interior of the sealing block 24. Therefore, a first pipe opening 211, an outlet sealing pipe 212, and a second pipe opening 213 are fixedly installed above the cleaning shell 21. The first pipe opening 211 and The second nozzle 213 is used to inject detergent and water into the interior of the cleaning shell 21, and the outlet sealing tube 212 is used to transmit the wiring harness connected to the top of the monitoring box 12. When cleaning, water can be injected into the first nozzle 211, and detergent can be injected into the outlet sealing tube 212. The sealing bearing 23 is driven to rotate by the rotation of the motor, thereby driving the sealing block 24 to rotate. A torsion spring is provided at the connection position between the sealing block 24 and the sealing bearing 23. Under normal conditions, the sealing blocks 24 are in mutual engagement. When the sealing bearing 23 drives the sealing blocks 24 to rotate rapidly, multiple sealing blocks 24 can be subjected to the effect of centrifugal force, thereby driving the sealing blocks 24 to open outwards, and being in a state like Figure 6 state, and the sealing block 24 can stir the water flow entering the cleaning shell 21, so that the water flow inside the cleaning shell 21 has a rotating effect, and the rotating water flow can flow into the interior of the monitoring box 12, thereby cleaning the surface of the detection element inside the monitoring box 12, and the interior of the cleaning shell 21 is passed through detergent, so that the oil and impurities inside the monitoring box 12 are cleaned by the rotation of the water flow and the effect of the detergent, and then the water is released by starting the transmission device 4 to complete the cleaning work.

[0029] It should be noted that, considering the need to understand the movement state of the cleaning device 3 during cleaning, the specific structure of the cleaning device 3 is disclosed, and when the sealing bearing 23 drives the sealing block 24 and the cleaning device 3 to rotate, it can drive the lifting plate 38 inside the cleaning device 3 to rotate, thereby driving the brush 34 to rotate. When the brush 34 rotates around the monitoring box 12 as the center of the circle, the outer wall of the monitoring box 12 can be cleaned, thereby brushing off the oil and floating objects adhered to the outside of the monitoring box 12, thereby achieving the cleaning effect.

[0030] refer to Figures 5 to 7 The cleaning device 3 further includes: a first limit block 35 fixedly mounted on the side wall of the fixed block 31 , wherein the first limit block 35 is used to limit the rotation angle of the second rotating block 32 .

[0033] It should be noted that, considering that the rotation of the sealing block 24 can drive the cleaning device 3 to rotate, and the second rotating block 32 inside the cleaning device 3 rotates, thereby driving the cleaning block 33 to rotate and adjust the angle of the brush 34, in the initial state, the fixed block 31 and the cleaning block 33 are in a parallel state, and a torsion spring is provided inside the connection part between the second rotating block 32 and the fixed block 31, and the sealing block 24 rotates quickly so that the cleaning device 3 is in a state such as Figure 5 state, thereby cleaning the attachments and oil stains at the bottom of the monitoring box 12, therefore, an adjusting protrusion 36 is provided on the side wall of the fixed block 31, and when the sealing block 24 rotates to drive the cleaning device 3 to rotate, the sealing protrusion 241 at the top of the sealing block 24 begins to move away from the center of the circle of the monitoring box 12, and the lifting rod 37 lifts the lifting plate 38, thereby lifting the adjusting protrusion 36, so that the adjusting protrusion 36 moves upward, and then drives the second rotating block 32 and the cleaning block 33 to rotate 90°, so that the brush 34 rotates to the position as shown in the figure. Figure 7state, the first telescopic rod 22 is retracted to the shortest state, so that the brush 34 can contact the bottom end of the monitoring box 12, thereby cleaning the bottom end of the monitoring box 12, improving the cleaning ability and increasing the cleaning position.

[0035] It should be noted that, considering that the bottom end of the cleaning shell 21 needs to be sealed when the monitoring box 12 is being cleaned, so as to separate the monitoring box 12 from the sludge, a transmission device 4 is provided inside the bottom end of the cleaning shell 21, and the second telescopic rod 41 inside the transmission device 4 is telescopic to drive the first sealing plate 42 to move, and the diameter of the first sealing plate 42 is the same as the size of the opening at the bottom end of the cleaning shell 21, so that the opening at the bottom end of the cleaning shell 21 is completely sealed, and a water suction port 43 is provided inside the center of the first sealing plate 42, and the water suction port 43 is connected to a water pump to pump out the sewage adsorbed by the lower end of the monitoring box 12, and when the interior of the cleaning shell 21 is filled with water, after the interior of the monitoring box 12 is cleaned, the water suction port 43 can still suck out the sewage after cleaning, thereby achieving the effect of sealing and replacing water after cleaning.

[0036] refer to Figures 7 to 9 The transmission device 4 also includes: a first groove 242 and a second groove 243 arranged inside the bottom end of the cleaning shell 21; a slide rod 46 slidably installed inside the first groove 242; a second sealing plate 44 fixedly installed at the end of the slide rod 46, the diameter of the second sealing plate 44 is the same as that of the second groove 243, and the second groove 243 is connected to the interior of the cleaning shell 21; a protruding rod 45 fixedly installed at the bottom center end of the second sealing plate 44; and a spring 47 fixedly installed on the outer wall of the slide rod 46.

[0037] It should be noted that a second sealing plate 44, a slide rod 46 and a spring 47 are provided inside the bottom end of the cleaning shell 21, so that the protruding rod 45 is squeezed during the movement of the first telescopic rod 22, thereby driving the protruding rod 45 to move in the direction of the slide rod 46, thereby opening the connection between the inside of the cleaning shell 21 and the second groove 243. When the sealing bearing 23 at the center of the first telescopic rod 22 moves to the same vertical line as the center of the second groove 243, the water pump can be started to pump out the water flow inside the cleaning shell 21, thereby preventing the sewage after the monitoring box 12 is cleaned from staying inside the cleaning shell 21, causing poor cleaning effect during the next cleaning.
