[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a regulating component.

[0020] 2. The present invention provides a flow-guiding mechanism. When the floating membrane rotates, it comes into contact with the inner wall of the drainage plate. The floating membrane impacts the sludge in the sewage, causing the sludge in the sewage to be drawn toward the absorption disk on the inner wall of the drainage plate. The sludge is then absorbed into the absorption disk through the internal storage cavity. By providing this mechanism, the sludge content in the sewage is reduced before the sewage comes into contact with the surface of the water quality sensor, thereby preventing large particles of sludge from adhering to the interior of the water quality sensor and affecting the accuracy and stability of the sensor's monitoring data.

[0021] 3. The present invention sets a telescopic mechanism, and the bottom of the discharge tube will squeeze the buffer bag and generate air pressure. The air pressure generated by the compression inside the buffer bag will be ejected through the injection hole on the surface of the discharge tube, thereby blowing the sludge attached to the inside of the contact groove of the water quality sensor and blowing the sludge out of the contact groove. By setting up this mechanism, the sludge that is difficult to remove from the inner wall of the water quality sensor can be removed, and small particles of sludge can be prevented from adhering to the inner wall of the water quality sensor and reducing the monitoring accuracy of the sensor.

[0022] 4. The present invention provides a compression ring, which compresses the buffer ring during the process of downward expansion and contraction of the compression ring, causing the buffer ring to shrink inward. At the same time, under the influence of the contraction of the buffer ring, one end of the telescopic column at the bottom of the buffer pad will also expand and contract inward. By providing this component, the impact force generated by the sewage on the guide plate can be buffered, thereby preventing the guide plate from loosening on the inner wall of the adjustment box after being impacted by sewage for a long time, which affects the monitoring efficiency of sewage inside the urban sewage treatment plant.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0034] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] Example 1: See Figures 1-4 The present invention provides a technical solution: a sewage monitoring and treatment device for an urban underground drainage network, comprising a base plate 1, a working box 2 being fixedly connected to the top of the base plate 1, a feed box 10 being fixedly connected to the right side of the working box 2, a water quality sensor 6 being fixedly connected to the left side of the inner wall of the working box 2, and an adjustment component 7 being provided on the surface of the feed box 10;

[0036] The adjustment component 7 includes:

[0037] Regulating box 701, regulating box 701 is fixedly connected to the left side of feed box 10, regulating box 701 is arranged on both sides of feed box 10, and guide plates 702 are rotatably connected on both sides of the inner wall of regulating box 701 through rotating shafts, and the top of guide plate 702 is fixedly connected to limit plate 703, and guide plate 702 is used to divert sewage. The sewage monitoring and treatment equipment is installed at the sewer outlet of the urban underground drainage network. At this time, the controller inside regulating box 701 can be remotely started to drive guide plate 702 to rotate on the inner wall of regulating box 701. When one end of guide plate 702 rotates to the top on the inner wall of regulating box 701 to the inside of feed cavity 5, and the sewage inside the underground pipe network is discharged from the sewer outlet, the sewage will flow into the inside of working box 2 from the inside of feed box 10.

[0038] Compression ring 704, compression ring 704 is fixedly connected to the bottom of guide plate 702, and the bottom of compression ring 704 is fixedly connected with buffer pad 705, and the bottom of buffer pad 705 is fixedly connected with buffer ring 707, and buffer ring 707 is fixedly connected to the bottom of the inner wall of working box 2. Buffer ring 707 is used to support guide plate 702. During this process, part of the sewage pouring in from the inside of feed box 10 will flow into the inside of feed cavity 5 through the surface of guide plate 702, and the inside of feed cavity 5 will flow this part of sewage into the sewer through the inside of sliding cavity 4, which can be used to divert sewage pouring into the urban pipe network, avoid excessive contact between a large amount of sewage flowing inside the pipe network and water quality sensor 6, and reduce the probability of sludge residue adhering to the inside of water quality sensor 6.

[0039] The adjustment component 7 also includes a telescopic column 706, one end of the telescopic column 706 is fixedly connected to the bottom of the buffer pad 705, and the end of the telescopic column 706 away from the buffer pad 705 is fixedly connected to the surface of the buffer ring 707. The top of the guide plate 702 is provided with a guide mechanism 8, the top of the working box 2 is fixedly connected to the communicator 3, the right side of the inner wall of the working box 2 is provided with a telescopic mechanism 9, the left side of the working box 2 is fixedly connected to the sliding cavity 4, and the top of the inner wall of the working box 2 is fixedly connected to the feeding cavity 5. The material cavity 5 is used to drain the sewage. When the guide plate 702 rotates on the inner wall of the regulating box 701, the compression ring 704 at the bottom of the guide plate 702 will be stretched. After the guide plate 702 adjusts the drainage angle of the sewage, the impact force generated by the flow of sewage on the surface of the guide plate 702 will cause the compression ring 704 at the bottom of the guide plate 702 to expand and contract inward. In the process of the compression ring 704 expanding and contracting downward, the buffer ring 707 will be compressed, causing the buffer ring 707 to shrink inward.

[0040] The compression ring 704 has the function of telescopic reset, and the telescopic column 706 can be telescoped inwardly and outwardly. An elastic bag is installed on the inner wall of the telescopic column 706. The compression ring 704 is used to adjust the guide plate 702. At the same time, affected by the contraction of the buffer ring 707, one end of the telescopic column 706 at the bottom of the buffer pad 705 will also telescope inwardly. Through multiple fixed telescopic columns 706, it can be ensured that the buffer ring 707 remains parallel and will not tilt outward during contraction, so that the impact force generated by sewage on the guide plate 702 can be buffered, so as to avoid the guide plate 702 from loosening on the inner wall of the adjustment box 701 after being impacted by sewage for a long time, affecting the monitoring efficiency of sewage inside the urban official website.

[0041] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The present invention provides a technical solution: the guide mechanism 8 includes a guide plate 801, which is fixedly connected to the top of the guide plate 702, and a connecting frame 803 is fixedly connected to both sides of the inner wall of the guide plate 801. The connecting frame 803 is fixedly connected to the top of the guide plate 702, and a cleaning component 804 is provided on the top of the connecting frame 803. The bottom of the inner wall of the guide plate 801 is fixedly connected to an absorption disk 802, and the absorption disk 802 is used to accommodate sludge in the sewage. When the sewage enters the surface of the guide plate 702 through the feed cavity 5, part of the sewage will flow on the inner wall of the guide plate 801. When the sewage flows, it will impact the floating film 8046 on the surface of the rotating ring 8041, thereby driving the rotating ring 8041 to rotate on the top of the connecting frame 803.

[0042] The cleaning assembly 804 includes a rotating ring 8041, the bottom of which is rotatably connected to the top of the connecting plate via a rotating shaft, and fixedly connected to the two sides of the rotating ring 8041 are clamping arms 8042, and the inner wall of the clamping arms 8042 is rotatably connected to a rotating column 8043, and the surface of the rotating column 8043 is fixedly connected to a floating membrane 8046, and the inner wall of the floating membrane 8046 is fixedly connected to a dividing block 8044, and the end of the floating membrane 8046 away from the rotating column 8043 is fixedly connected to an absorption tube 8045, and the rotating column 8043 is used to drive the floating membrane 8046 to rotate. When 8041 rotates, it drives the floating membranes 8046 on both sides to rotate on the inner wall of the drainage plate 801. When the floating membranes 8046 rotate, they come into contact with the inner wall of the drainage plate 801, and the sludge in the sewage is slapped by the floating membranes 8046, so that the sludge in the sewage is slapped and drawn to the absorption plate 802 on the inner wall of the drainage plate 801, and the sludge is absorbed into the absorption plate 802 through the internal storage cavity. When the floating membranes 8046 come into contact with the inner wall of the drainage plate 801, they bend inward. During the contact process, part of the sludge in the sewage will enter the absorption tube 8045.

[0043] The floating membrane 8046 has the characteristics of being flexible and stretchable. The surface of the absorption tube 8045 is provided with an absorption groove, and the interior of the absorption disk 802 is provided with a storage cavity. The absorption tube 8045 is used to absorb the sludge inside the sewage. After the floating membrane 8046 is used for a long time, the sludge will adhere to and accumulate on the inner wall of the dividing block 8044. When cleaning is required, the working box can be taken out from the inside of the urban official website, and the sludge blocks accumulated inside the dividing block 8044 are cleaned first, and the sludge inside the absorption disk 802 is cleaned at the same time. Finally, the absorption disk 802 is removed from the inside of the guide plate 801 to clean the sludge in the storage cavity inside the absorption disk 802. Before the sewage comes into contact with the surface of the water quality sensor 6, the sludge content in the sewage is first reduced to prevent large particles of sludge from adhering to the inside of the water quality sensor 6, thereby affecting the accuracy and stability of the sensor's monitoring data.

[0044] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8 The present invention provides a technical solution: the telescopic mechanism 9 includes a telescopic tube 901, one end of the telescopic tube 901 is fixedly connected to the right side of the inner wall of the working box 2, and the inner wall of the telescopic tube 901 is fixedly connected with a telescopic cavity 902. The telescopic tube 901 is used to accommodate the telescopic cavity 902. During the long-term contact between the water quality sensor 6 and the sewage, small particles of sludge will adhere to the contact groove on the surface of the water quality sensor 6, thereby reducing the monitoring sensitivity of the water quality sensor 6. At this time, the telescopic device inside the telescopic tube 901 is remotely started to push the purification rod 9031, so that the purification rod 9031 is extended from the inside of the telescopic cavity 902 to the outside to the surface of the water quality sensor 6.

[0045] The purification assembly 903 includes a purification rod 9031 that is slidably connected to the inner wall of the telescopic cavity 902. A partition 9033 is fixedly connected to the inner wall of the purification rod 9031. A buffer capsule 9032 is fixedly connected to the inner wall of the purification rod 9031. A material removal pipe 9034 is slidably connected to the inner wall of the buffer capsule 9032. The top of the material removal pipe 9034 is provided with an absorption hole. The partition 9033 is used to form a closed space inside the purification rod 9031. When the purification rod 9031 is extended from the inside of the telescopic cavity 902, the material removal pipe One end of 9034 will pop out from the inside of the buffer bag 9032. During the movement of the purification rod 9031 on the surface of the water quality sensor 6, the top of the discharge tube 9034 will squeeze the inside of the contact groove on the surface of the water quality sensor 6, and the sludge inside the contact groove will be scraped into the inside through the top pipe mouth of the discharge tube 9034. At the same time, due to the collision between the top of the discharge tube 9034 and the inside of the contact groove on the surface of the water quality sensor 6, the bottom of the discharge tube 9034 will squeeze the buffer bag 9032 and generate air pressure.

[0046] A spray hole is provided on the surface of the discharge tube 9034, and the buffer bag 9032 is made of a compressible air film material. The buffer bag 9032 is used to support the discharge tube 9034. The air pressure generated by the internal compression of the buffer bag 9032 will be sprayed out through the spray hole on the surface of the discharge tube 9034, thereby blowing the sludge attached to the inside of the contact groove of the water quality sensor 6. When the sludge is blown out from the inside of the contact groove, part of the blown sludge will settle into the sealed area separated by multiple partitions 9033 inside the purification rod 9031. Finally, when cleaning the sludge inside the working box, the sludge on the inner wall of the purification rod 9031 can be processed at the same time, and the sludge that is difficult to remove on the inner wall of the water quality sensor 6 can be removed to prevent small particles of sludge from adhering to the inner wall of the water quality sensor 6 and reducing the monitoring accuracy of the sensor.
