Detailed Implementation

[0031] The following will refer to the appendix in the embodiments of this utility model. Figure 1 To be continued Figure 8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1 to 8As shown, this utility model provides an online monitoring and sampling device for the inlet of a sewage treatment plant, including: a connecting component 1, a collecting component 2, a cleaning component 3, and a linkage component 4.

[0033] The connecting assembly 1 includes an equipment housing 11, which is connected to a connecting pipe 13. A fixing sleeve 12 is fixedly connected to the bottom end of the connecting pipe 13, and the fixing sleeve 12 is connected to the connecting pipe 13. Thus, the equipment housing 11, the connecting pipe 13, and the fixing sleeve 12 form a complete communicating channel. Meanwhile, a partition plate 14 is fixedly connected to the inner wall of the equipment housing 11, dividing the inner cavity of the equipment housing 11 into two independent inner cavities. The upper cavity of the partition plate 14 is named the equipment cavity, and the lower cavity is named the liquid flow cavity. Additionally, a protective housing 17 is fixedly connected to the front end of the equipment housing 11.

[0034] To reduce the amount of large debris entering the equipment box 11 and connecting pipe 13 during wastewater collection, a filter screen 5 is fixedly connected to the bottom end of the fixed sleeve 12.

[0035] A connecting frame 16 is fixedly connected to the middle of the equipment box 11, and a fixing frame 15 is fixedly connected to the bottom of the connecting frame 16. The fixing frame 15 is U-shaped, and the inner wall of the fixing frame 15 faces downward.

[0036] Specifically, in use, the fixing frame 15 in the connecting assembly 1 of this utility model is snapped onto the top of the side wall of the coarse screen tank in the water inlet channel, and then the fixing frame 15 is fixedly connected to the side wall of the screen tank by multiple bolt groups. Then, the fixing frame 15 and the filter screen 5 at its bottom are inserted into the sewage tank below the liquid surface.

[0037] The collection component 2 includes a three-way pipe 21 inserted into one side of the equipment box 11. A collection bottle 22 is fixedly connected to the outlet of the lower side of the three-way pipe 21. The end of the three-way pipe 21 away from the equipment box 11 is solid. An air hole is opened on the top side of the three-way pipe 21 away from the equipment box 11. A waterproof and breathable membrane is fixedly connected to the inner wall of the air hole, thus allowing only gas to enter and exit the three-way pipe 21, while preventing moisture from entering and exiting the three-way pipe 21 through the air hole.

[0038] The collection assembly 2 also includes an impeller 31 located inside the equipment housing 11 and below the partition plate 14, with the impeller 31 rotatably connected to the equipment housing 11. When the impeller 31 rotates, it generates negative pressure in the connecting pipe 13 and the three-way pipe 21, causing the wastewater sample to pass sequentially through the filter screen 5, the connecting pipe 13, and then be drawn into the three-way pipe 21, finally flowing into the collection bottle 22.

[0039] The cleaning assembly 3 includes a connecting sleeve 32 connected to the equipment box 11 and the fixed sleeve 12 on the side away from the tee pipe 21 via a fixing block. A rotating rod 33 is rotatably connected inside the sleeve, and an actuating rod 34 is fixedly connected to the bottom end of the rotating rod 33. The actuating rod 34 is in contact with the bottom end of the filter screen 5.

[0040] It should be noted that the lever 34 in this embodiment is equipped with a bristle assembly. When cleaning the filter screen 5, the bristles on the bristle assembly can penetrate into the mesh of the filter screen 5 to further remove the blockage of the filter screen 5.

[0041] Furthermore, when the rotating rod 33 rotates, the actuating rod 34 can pry open the large pieces of dirt at the bottom of the filter screen 5, preventing the dirt from clogging the filter screen 5 and affecting the subsequent collection and testing.

[0042] The equipment housing 56 is fixedly connected to the upper part of the equipment box 11 on the side away from the T-joint 21. The linkage assembly 4 includes a drive unit 41 and a swing unit 42. The swing unit 42 is located in the equipment housing 56.

[0043] The drive unit 41 includes a drive motor 411 fixedly connected to the top of the connecting frame 16. A rotating hole 1 is opened at the upper rear end of the equipment box 11. The output shaft of the drive motor 411 passes through the rotating hole 1 at the rear end of the equipment box 11 and is fixedly connected to a bevel gear 412. The front end of the bevel gear 412 meshes with a bevel gear 413, and the front end of the bevel gear 413 meshes with a bevel gear 414.

[0044] The front end of the bevel gear 414 is fixedly connected to a drive shaft 54. The front end of the equipment housing 11 has a rotating hole 2 communicating with the inner cavity of the protective housing 17. The drive shaft 54 ​​is rotatably connected to the rotating hole 2. Simultaneously, the front end of the drive shaft 54 ​​is located inside the protective housing 17 and fixedly connected to a pulley 51. Below the pulley 51 is a pulley 52. ​​The pulleys 51 and 52 are connected by a belt 53. It should be noted that both pulleys 51 and 52 are synchronous pulleys, and the belt 53 is a synchronous belt. This ensures the accuracy of power transmission and prevents slippage that could lead to a decrease in subsequent transmission accuracy. The rear end of the pulley 52 is fixedly connected to a drive shaft 55. The lower part of the front end of the equipment housing 11 has a rotating hole 3 communicating with the inner cavity of the protective housing 17. The drive shaft 55 is rotatably connected within the rotating hole 3. Simultaneously, the rear end of the drive shaft 55 is located in the protective housing 17 and fixedly connected to the impeller 31.

[0045] Furthermore, when the drive motor 411 is running, the meshing of bevel gear 1 412, bevel gear 2 413, and bevel gear 3 414 transmits power to pulley 1 51. Then, through the connection of belt 53, the power is transmitted to pulley 2 52. Pulley 2 52 then drives impeller 31 to rotate via drive shaft 2 55, thereby generating a negative pressure effect for pumping.

[0046] A rotating hole four is opened on the upper part of the side of the equipment box 11 away from the three-way pipe 21, and a rotating hole five is opened in the middle of the bottom end of the equipment shell 56.

[0047] The swing part 42 includes a fixed shaft 427, which is rotatably connected to the rotating hole 4. The fixed shaft 427 is fixedly connected to the bevel gear 3 414. The other end of the fixed shaft 427 is fixedly connected to a connecting block 426. A through hole is opened on the connecting block 426, and a connecting shaft 425 is inserted into the through hole. A stop block is fixedly connected to the side of the connecting shaft 425 near the fixed shaft 427 to prevent the connecting shaft 425 from detaching from the connecting block 426. The other end of the connecting shaft 425 is fixedly connected to a guide block 424. A guide shaft 423 is inserted into the guide block 424. The top and bottom ends of the guide shaft 423 are fixedly connected to a fixing bracket 422. A rotating shaft 421 is fixedly connected to both fixing brackets 422. The top end of the rotating shaft 421 is rotatably connected to the top wall of the equipment housing 56, and the bottom end of the rotating shaft 421 passes through the rotating hole 5 and is fixedly connected to the rotating rod 33.

[0048] Specifically, when the technician turns on the drive motor 411, the cleaning component 3, the linkage component 4, and the collection component 2 begin to operate.

[0049] The drive shaft of the drive motor 411 drives the first bevel gear 412 to rotate, which in turn drives the second bevel gear 413 to rotate, causing the fixed shaft 427 and the connecting block 426 to rotate. The connecting block 426 drives the guide block 424 to rotate through the connecting shaft 425, which is rotatably connected. This causes the guide block 424 to slide up and down on the guide shaft 423, causing the guide shaft 423 to swing back and forth. The guide shaft 423 drives the rotating shaft 421 and the rotating rod 33 to rotate back and forth through the fixed frame 422, causing the rotating rod 33 to drive the bottom actuating rod 34 to clean and brush the bottom of the filter screen 5.

[0050] At the same time, bevel gear 2 413 drives bevel gear 3 414 to rotate, causing pulley 1 51 to drive pulley 2 52 to rotate via belt 53, which in turn causes impeller 31 to rotate below partition plate 14. When impeller 31 rotates, negative pressure is generated in connecting pipe 13 and three-way pipe 21, so that sewage sample is sequentially drawn through filter screen 5 and connecting pipe 13 into three-way pipe 21 and flows into collection bottle 22 for collection and analysis.

[0051] In summary, the online monitoring and sampling device for the inlet of a wastewater treatment plant provided by this utility model has at least the following advantages: through the linkage component 4, the toggle lever 34 is automatically driven to clean the filter screen and extract wastewater when the drive motor 411 is started, realizing the simultaneous sampling and cleaning, avoiding monitoring interruption caused by filter screen blockage, and significantly reducing the frequency of manual cleaning and maintenance costs, effectively improving the continuity and stability of equipment operation.
