DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1

[0031] A rotary screen dirt remover, such as Figure 1-5As shown, it includes a grille frame 1 and a mounting shell 2, and a plurality of lifting columns 14 are fixedly connected on both sides of the mounting shell 2. Specifically, two lifting columns 14 are respectively arranged on both sides of the mounting shell 2. The four lifting columns 14 can stably maintain the two lifting arms 12 to rise and fall smoothly. The top of the lifting column 14 is fixedly connected with the lifting arm 12, and the lifting arm 12 is rotatably connected to both sides of the top of the grille frame 1. An arc-shaped slide groove 5 is arranged at the bottom end of the grille frame 1, and a sliding rod 6 is slidably connected in the slide groove 5. The sliding rod 6 is simultaneously slidably connected in the slide rail 4, and the slide rail 4 is arranged at both ends of the sliding rod 6 and is fixedly connected to the bottom surface in the water channel.

[0032] See also Figure 1 An arc-shaped baffle 15 is fixedly connected to the top of the mounting shell 2. The projection of the arc-shaped baffle 15 toward the cleaning roller 13 can completely cover the cleaning roller 13. The arc-shaped baffle 15 can well block the debris thrown out by the rotation of the cleaning roller 13, so that the debris can accurately fall into the debris discharge port at the bottom of the mounting shell 2 and fall together with the debris dropped from the top of the grille belt 3.

[0033] See also Figure 1-4 A cleaning roller 13 is rotatably connected between the lifting arms 12 connected to both sides of the grille frame 1. The cleaning roller 13 contacts the grille belt 3. The cleaning roller 13 connected to the lifting arms 12 is used to clean the grille belt 3, so that the debris on the grille belt 3 can fall better, effectively avoiding the accumulation of debris on the grille belt 3 and causing the water permeability of the grille belt 3 to decrease, thereby avoiding the clogging of the dirt remover. A driving motor 10 is fixedly connected to one side of the grille frame 1, and a rotating shaft at the top of the grille belt 3 is rotatably connected to a transmission column at the end close to the driving motor 10. 11. A transmission belt is connected between the output end of the driving motor 10 and the driving column 11, and a transmission belt is connected between the driving column 11 and the rotating shaft of the cleaning roller 13. When the driving motor 10 drives the grille belt 3 to move, the cleaning roller 13 is rotated synchronously. Since the rotation direction of the cleaning roller 13 is the same as the rotation direction of the rotating shaft of the grille belt 3, but the cleaning roller 13 and the grille belt 3 are close to each other, the cleaning roller 13 can clean the debris on the grille belt in the opposite direction of the moving direction of the grille belt 3 when it rotates, effectively avoiding the residue of debris on the grille belt.

[0034] Embodiment 2

[0035] A rotary screen dirt remover, such as Figure 1-5 As shown, air bags 7 are provided on both sides of the grille frame 1. The air bags 7 on both sides of the grille frame 1 can seal the inner wall of the water channel and both sides of the grille frame 1 after the grille frame 1 is placed in water, thereby preventing debris from flowing away from both sides of the grille frame 1. At the same time, the air bags 7 on both sides of the grille frame 1 can also provide a certain buoyancy for the grille frame 1, which can effectively reduce the pressure applied by the slide rail 4 at the bottom end of the grille frame 1, and can effectively extend the service life of the slide rail 4.

[0036] See also Figure 1-5 Air pumps 9 are provided on both sides of the mounting shell 2, and the air outlet of the air pump 9 is connected to the air inlet of the airbag 7 through the air guide tube 8. A pressure relief port is provided at the bottom of the airbag 7. The air pump 9 is continuously operated to inflate the airbag 7. When the pressure in the airbag 7 exceeds the threshold, the excess gas will be discharged from the bottom of the airbag 7, keeping the airbag 7 in a full state at all times, so that the airbag 7 can continue to fit the inner wall of the canal. The airbag 7 is arranged along the length direction of the grid frame 1, and is arranged in an arc shape around the bottom of the grid frame 1 to avoid the appearance of gaps at the bottom of the grid frame 1 through which debris can pass after the angle of the grid frame 1 is adjusted.

[0037] The working principle of the utility model is as follows: when the inclination angle of the grille belt 3 needs to be adjusted, the lifting column 14 is extended, so that the lifting arm 12 is raised, thereby pulling the bottom end of the grille frame 1 toward the mounting shell 2, and the sliding rod 6 slides to the bottom end in the slide groove 5, and the sliding rod 6 also slides synchronously in the slide rail 4 toward the mounting shell 2, and the inclination angle of the grille belt 3 increases. Conversely, when the lifting column 14 is shortened, the bottom end of the grille frame 1 moves away from the mounting shell 2, and the inclination angle of the grille belt 3 decreases.

[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
