The connecting column 204a is rotatably connected inside the oil-water separator body 101, and the other end of the movable rod 204b penetrates through the collection box 103 and the movable rod 204b and extends to the outside of the oil-water separator body 101.

[0053] On both sides of the surface of the connecting column 204a, reverse threads are provided, and the movable rod 204b is located at the threaded part. The inner wall of the movable rod 204b is threadedly connected to the connecting column 204a. When it is necessary to gather the oil stains on the inner bottom wall of the collection box 103, the connecting column 204a is rotated, and the movable rod 204b is driven to move towards each other through the threads on the connecting column 204a, so as to gather the oil stains on the inner bottom wall of the collection box 103, so that the oil stains can be quickly discharged from the sewage pipe.

[0054] Specifically, the top of the movable rod 204b is inclined, and the inclination angle is 45 degrees.

[0055] By setting the top of the movable rod 204b to be inclined, the oil stains flow to the bottom of the collection box 103 when being scraped off, so as to facilitate the subsequent gathering of the oil stains.

[0056] Specifically, the collecting member 204 further includes a limiting rod 204c. The limiting rod 204c is movably connected to the movable rod 204b, and the end of the limiting rod 204c is fixed to the inner wall of the collection box 103.

[0057] Through the arrangement of the limiting rod 204c, it is used to limit the movable rod 204b, so that the movable rod 204b remains stable when moving.

[0058] When in use, first press down the pressing plate 202a. The push rod 201 is driven to move downward through the pressing plate 202a. The push rod 201 drives the connecting plate 203a and the first spring 202c to move, and the first spring 202c is deformed by the force. At the same time, the connecting plate 203a drives the first scraper 203b to move, and the first scraper 203b drives the second scraper 203c to move, so as to scrape the oil stains on the inner walls around the collection box 103. The lower end of the collection box 103 is conical. When the first movable plate 203b gradually moves downward, the two first scrapers 203b will move towards the inside of the connecting plate 203a, so as to keep the side of the scraper always in contact with the inner wall of the collection box 103. After the oil stains on the inner wall of the collection box 103 are scraped off, release the pressing plate 202a. At this time, the pressing plate 202a is pushed to move by the restoring elastic force of the first spring 202c. The pressing plate 202a drives the push rod 201 to move upward. The push rod 201 drives the connecting plate 203a to move. The connecting plate 203a drives the second scraper 203c to move upward through the first scraper 203b. At the same time, the connecting block 203e is pushed to move by the restoring elastic force of the second spring 203f. The connecting block 203e drives the two first scrapers 203b to move towards each other, and the two first scrapers 203b are reset. When it is necessary to gather the oil stains on the inner bottom wall of the collection box 103, the connecting column 204a is rotated, and the movable rod 204b is driven to move towards each other through the threads on the connecting column 204a, so as to gather the oil stains on the inner bottom wall of the collection box 103, so that the oil stains can be quickly discharged from the sewage pipe.
