Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a wastewater sampling collection box that is easy to clean, including a box body 1 and a liquid injection main pipe 2. The box body 1 has a circular collection chamber and a square filter chamber inside. A push handle is fixed to one side wall of the box body 1, and casters are fixed to the bottom of the box body 1. The push handle and casters can move the box body 1, improving the flexibility of wastewater sampling. A sealing door is provided on the other side of the box body 1. Rotating the sealing door allows for quick disassembly and assembly of the filter plate 9, facilitating the cleaning of impurities filtered on the top of the filter plate 9. The liquid injection main pipe 2 is located in the box body 1. On one side, a three-way pipe 3 is fixed to one side of the box body 1. The three-way pipe 3 can allow the collected sewage to flow into the two circular collection chambers respectively. One end of the liquid injection main pipe 2 is fixedly installed at one end of the three-way pipe 3. The other two ends of the three-way pipe 3 are fixedly installed with liquid injection branch pipes 7. The other end of the liquid injection branch pipes 7 is located inside the square filter chamber. A fixing frame 4 is fixed to the top of the box body 1. The fixing frame 4 has a fixing effect on the cleanable inner wall stirring component 5. The cleanable inner wall stirring component 5 is fixedly installed on the inner wall of the top of the fixing frame 4. A self-cleaning liquid drainage component 6 is fixedly installed on the other side of the box body 1.

[0029] A limiting plate 8 is fixed inside the square filter chamber. The bottom of the limiting plate 8 contacts the top of the filter plate 9. The limiting plate 8 has a limiting effect on the filter plate 9, preventing the filter plate 9 from moving up and down inside the square filter chamber. The filter plate 9 is set inside the square filter chamber, and the limiting plate 8 is located above the filter plate 9.

[0030] One application of this embodiment is as follows: one-way valves are provided on the outside of the two injection branch pipes 7, and the other ends of the two injection branch pipes 7 are respectively located inside the two square filter chambers, which facilitates the classification and collection of sewage. The filter plate 9 can filter out larger impurities contained in the sewage. The filtered sewage can flow into the circular collection chamber under its own gravity. The sewage inside the circular collection chamber can be stirred by the cleanable inner wall stirring component 5 to prevent the collected sewage from stratifying. It can make the various components in the sewage fully mixed, ensuring that the collected sample is representative. It can also clean the inner wall of the circular collection chamber. Finally, the sewage inside the circular collection chamber can be discharged by the self-cleaning drainage component 6, and the inner wall of the pipe can be cleaned.

[0031] The cleanable inner wall mixing assembly 5 includes a mixing motor 501 and a rotating shaft 502. The mixing motor 501 is fixedly installed on the top inner wall of the fixed frame 4. The top of one of the rotating shafts 502 is installed at the output end of the mixing motor 501. The two rotating shafts 502 are located inside the two circular collection chambers respectively. The bottom of the two rotating shafts 502 is rotatably installed on the bottom inner wall of the box body 1. Synchronous pulleys 503 are fixedly installed on the outside of the two rotating shafts 502. A synchronous belt 504 is meshed between the two synchronous pulleys 503. A mixing frame 505 and a conveying blade 506 are fixed on the outside of the two rotating shafts 502. The mixing frame 505 and the conveying blade 506 are located inside the circular collection chamber, which facilitates the thorough mixing of the sewage inside the circular collection chamber.

[0032] In this embodiment, the stirring motor 501 drives one of the rotating shafts 502 to rotate, and one of the synchronous pulleys 503 rotates along with the rotating shaft 502. Teeth are provided on the outer sides of both synchronous pulleys 503 and the inner side of the synchronous belt 504, so that the synchronous belt 504 meshes with both synchronous pulleys 503. Under the action of the synchronous belt 504, the two synchronous pulleys 503 can rotate simultaneously, thereby driving both rotating shafts 502 to rotate simultaneously. The outer side of the stirring frame 505 contacts the inner wall of the circular collection chamber, allowing the stirring frame 505 to not only stir the wastewater and prevent stratification, but also clean the inner wall of the circular collection chamber. This reduces corrosion and damage to the chamber 1 caused by impurity accumulation and microbial growth, extends the service life of the chamber 1, and reduces replacement and maintenance costs. Furthermore, the conveying blades 506 can transport the wastewater from the bottom of the circular collection chamber to the top, ensuring the representativeness of the collected samples and thus improving the accuracy of subsequent analysis results.

[0033] The self-cleaning drainage assembly 6 includes a mounting plate 601 and a drainage pipe 602. The mounting plate 601 is fixedly installed on the other side of the housing 1. The mounting plate 601 can fix the electric push rod 603. One end of the drainage pipe 602 passes through and is fixed inside the circular collection chamber. The electric push rod 603 is fixedly installed on the other side of the mounting plate 601. The other end of the electric push rod 603 is fixed with a connecting plate 604. The connecting plate 604 can connect the electric push rod 603 and the piston 605 together, so as to facilitate flexible adjustment of the position of the piston 605. The piston 605 is fixedly installed on the connecting plate 604. The piston 605 is located inside the drainage pipe 602. A circular rubber scraper is fixed on the outside of the piston 605.

[0034] In this embodiment, when the electric push rod 603 is stretched, it can drive the connecting plate 604 to move. The piston 605 can move along with the connecting plate 604. The piston 605 consists of a piston rod, a piston head, and a circular rubber scraper. The piston head and the circular rubber scraper can block the drain pipe 602. As the piston head and the circular rubber scraper separate from the drain pipe 602, sewage can flow out through the drain pipe 602. At the same time, the circular rubber scraper can clean the inner wall of the drain pipe 602, extending the service life of the drain pipe 602.

[0035] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
