[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figures 3-6As shown in the figure, a sundry interception grille plate for sewage treatment includes a main grille frame 1, an extended grille frame 4 and an anti-blocking cleaning component 7. Above the rear side of the main grille frame 1, an upper plate 2 is fixed. And below the middle of the upper plate 2, a telescopic rod 3 is installed. The lower side of the telescopic rod 3 is installed with an extended grille frame 4, and the extended grille frame 4 is in an "L" shape. Vertically fixed in front of the extended grille frame 4 is a stop frame 5. And inside the main grille frame 1, the extended grille frame 4 and the stop frame 5, an interception net 6 is fixed. On the front sides of both sides of the extended grille frame 4, sliding strips 8 are fixed, and the sliding strips 8 are in a "T" shape. On the rear sides of both sides of the main grille frame 1, limit sliding frames 9 are provided. At the same time, the sliding strips 8 and the limit sliding frames 9 are in sliding connection. The main grille frame 1 is in a rectangular structure, and the symmetry centers of the main grille frame 1 and the extended grille frame 4 coincide. On the outer walls of the left and right sides of the main grille frame 1, connecting blocks 10 are fixed. On the outside between two adjacent connecting blocks 10, a connecting frame 11 is slidably installed, and the connecting frame 11 is in a "king" shape. Two adjacent main grille frames 1 can be spliced and assembled together. During assembly, the connecting frame 11 in a "king" shape is slidably installed on the outside of the connecting blocks 10 on the sides of the two main grille frames 1. The splicing is simple and convenient, suitable for interception processing of different widths. Through the telescopic movement of the telescopic rod 3, it is convenient to drive and adjust the position of the extended grille frame 4 to adjust the total height of the main grille frame 1 and the extended grille frame 4, suitable for water levels of different heights. At this time, the sliding cooperation between the sliding strips 8 and the limit sliding frames 9 makes the movement of the extended grille frame 4 stable. The extended grille frame 4 is in an "L" shape and a stop frame 5 is vertically fixed in front. When in a non-draining state after interception, the U-shaped frame formed by the extended grille frame 4 and the stop frame 5 can collect some sundries, which is convenient for cleaning these sundries.

[0018] As Figures 1-2As shown, an anti-clogging cleaning component 7 is installed in the middle of the front side of the main grid frame 1. The anti-clogging cleaning component 7 includes a fixed frame 701, a drive motor 702, and a lead screw 703. The drive motor 702 is installed on the upper outer side of the fixed frame 701, and the lead screw 703 is rotatably installed inside the fixed frame 701. The anti-clogging cleaning component 7 also includes a movable sleeve 704 and a connecting block 705. The movable sleeve 704 is sleeved on the outer side of the lead screw 703, and the connecting block 705 is fixed on the front side of the movable sleeve 704. The anti-clogging cleaning component 7 also includes a connecting plate 706 and a cleaning brush 707. The connecting plate 706 is fixed on the outer side of the connecting block 705, and the connecting plate 706 has a "U" shaped structure. The cleaning brushes 707 are fixed on both sides of the connecting plate 706, and the cleaning brushes 707 are attached to the outer surface of the main grid frame 1 and its internal interceptor mesh 6. The anti-clogging cleaning component 7 also includes a dustproof fold. The stacked cover 708, the movable sleeve 704, and the connecting block 705 are slidably connected to the inner wall of the fixed frame 701. The upper and lower sides of the connecting block 705 are connected to the upper and lower sides of the fixed frame 701 by a dustproof folding cover 708. The main grid frame 1, the extended grid frame 4, and the baffle frame 5 are all fixed with an intercepting net 6 for intercepting debris during sewage treatment. At the same time, the main grid frame 1 and the extended grid frame 4 are all fixed with grid bars to strengthen the structure. The dustproof folding cover 708 is used to protect the inside of the fixed frame 701 from pollution. The drive motor 702 can easily drive the screw 703 to rotate, thereby driving the outer movable sleeve 704 and the connecting block 705 to move. This allows the connecting block 705 to drive the connecting plate 706 and the cleaning brush 707 to move up and down, thereby cleaning the outer surface of the main grid frame 1 and its internal intercepting net 6 to prevent blockage.

[0019] In summary, such as Figures 1-6 As shown, the wastewater treatment debris interception grid can be used by first assembling two adjacent main grid frames 1 in pairs. During assembly, the "king" shaped assembly frame 11 is slidably installed on the outside of the assembly block 10 on the side of the two main grid frames 1, making it suitable for interception treatment of different widths. Then, the position of the extension grid frame 4 can be adjusted by the extension and retraction of the telescopic rod 3 to adjust the total height of the main grid frame 1 and the extension grid frame 4, which is suitable for water levels of different heights. At this time, the sliding cooperation between the sliding strip 8 and the limiting sliding frame 9 makes the extension grid frame 4 move smoothly. The main grid frame 1, the extended grid frame 4, and the baffle frame 5 are all fixed with an interception net 6 for intercepting debris during sewage treatment. At the same time, the main grid frame 1 and the extended grid frame 4 are all fixed with grid bars to strengthen the structure. The extended grid frame 4 has an "L" shaped structure and a baffle frame 5 is fixed vertically on the front side. This allows the U-shaped frame formed by the extended grid frame 4 and the baffle frame 5 to collect some debris in the non-drainage state after interception, thus facilitating the cleaning of this debris. During use, the dustproof folding cover 708 is used to protect the inside of the fixed frame 701 from dirt. It can also periodically drive the rotation of the lead screw 703 by the drive motor 702, thereby driving the movement of the outer moving sleeve 704 and the connecting block 705. This allows the connecting block 705 to drive the connecting plate 706 and the cleaning brush 707 to move up and down, thereby cleaning the outer surface of the main grid frame 1 and its internal interception net 6 to prevent blockage. This completes the use of the wastewater treatment debris interception grid.
