The aeration mechanism forms the main body of the aerator, including an air chamber 1 and an aeration branch pipe 2. In order to improve the aeration efficiency, the air chamber 1 consists of two parallel branches. In order to increase the air volume of the air chamber 1, the air chamber 1 in this embodiment is selected as a tube without an internal support tube. The counterweight mechanism is fixed below the air chamber 1 to provide counterweight for the aerator main body, so that it can sink underwater and prevent the aeration tube from floating. The aeration branch pipe 2 is evenly arranged with multiple branches along the extension direction of the air chamber 1. Preferably, there are an even number of branches. In this embodiment, there are 8 branches. The two ends of the aeration branch pipe 2 are respectively connected to the air chamber 1 and perpendicular to the air chamber 1.

The stabilizing bracket 4 is rectangular and is positioned above the aeration branch pipe 2, extending from the first end to the last end of the air chamber 1. The drive cylinder 3 is mounted on a counterweight mechanism and is parallel to the aeration branch pipe 2. The middle part of the stabilizing bracket 4 is fixed to the output end of the drive cylinder 3, which is used to drive the stabilizing bracket 4 to slide relative to the aeration branch pipe 2. The front and rear sides of the stabilizing bracket 4, i.e., the sides of the stabilizing bracket 4 closest to the two air chambers 1, have the freedom to slide to touch both ends of the aeration branch pipe 2 under the drive of the drive cylinder 3. Multiple cleaning scrapers 5 are arranged on the front and rear sides of the stabilizing bracket 4. The top of the cleaning scraper 5 is fixed to the lower end of the stabilizing bracket 4. The cleaning scraper 5 is positioned corresponding to the aeration branch pipe 2 and is fitted onto the aeration branch pipe 2. The cleaning scraper 5 and the aeration branch pipe 2 are in frictional contact with each other, and the scraper 5 has the freedom to slide relative to the aeration branch pipe 2 under the drive of the driving cylinder 3, thereby cleaning the outer surface of the aeration branch pipe 2 and removing adsorbed impurities. To ensure the cleaning effect of the cleaning scraper 5 and avoid scratching the aeration branch pipe 2, in this embodiment, the cleaning scraper 5 is selected as a rubber sleeve or rubber scraper manufactured by molding EPDM material. Whether it is a rubber sleeve or a rubber scraper, it is only necessary to cover the aeration hole setting range on the aeration branch pipe 2. No specific limitation is made in this embodiment.

[0026] Furthermore, in this embodiment, the drive cylinders 3 are arranged in pairs and respectively mounted on the counterweight mechanism below the two air chambers 1 via mounting seats.

The lower end of the stable balance support 4 extends below the air chamber 1 and is sleeved on the counterweight pipe 10 in a hoop shape, and is gap matched with the counterweight pipe 10. In order to provide stable counterweight for the aerator body, the number of the counterweight pipe 10 is set to be multiple, and is parallel to the aeration branch pipe 2, in actual operation, the number of the counterweight pipe needs to be set according to the specific extension length of the air chamber 1, which is not limited in the embodiment, and the multiple counterweight pipes 10 are evenly arranged along the extension direction of the air chamber 1. In addition, the filling in the counterweight pipe 10 can be sand or metal powder, in the embodiment, in order to ensure the sinking effect of the aerator body, iron powder is filled into the counterweight pipe 10, and both ends of the counterweight pipe 10 are sealed.
