Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 8, the embodiment provides the following technical solutions:

the water conservancy desilting suction opening comprises a desilting pipe 1, a rotary filter ball 2 and a circular brush 3, wherein two bearings 11 are symmetrically and fixedly connected to the inner side wall of the desilting pipe 1 close to the pipe opening; the rotary filter ball 2 comprises a cavity ball 21 with a plurality of through holes 24 on the surface, a rotating shaft 22 which penetrates through the cavity ball 21 and has two ends extending out of the cavity ball 21 and fixedly connected with the cavity ball 21, and a water flushing impeller 23 which is fixedly connected with the rotating shaft 22 and arranged in the inner cavity of the cavity ball 21; two ends of a rotating shaft 22 of the rotary filter ball 2 are respectively and rotatably connected through two bearings 11 arranged on the inner side wall of the silt pumping pipe 1 close to the pipe orifice, so that the rotary filter ball 2 is rotatably connected with the silt pumping pipe 1; the circular brush 3 is nested on the inner side wall of the silt pumping pipe 1 close to the pipe orifice.

The bearing 11 is a one-way rotary bearing.

Referring to fig. 1-3, in order to prevent the suction opening from being blocked by large objects, such as bricks, stones, branches, plastic bags, etc., the embodiment further includes a grid cover 4, and the grid cover 4 is sleeved on the outer side wall of the silt pumping pipe 1 near the pipe opening.

Referring to fig. 1, 3 and 8, the inner ring side of the circular brush 3 is provided with bristles 31, the bristles 31 are in contact connection with the outer surface of the rotary filter ball 2 to brush off sludge adhered to the outer surface of the rotary filter ball 2, and in order to increase the effect of removing sludge on the outer surface of the rotary filter ball 2, the heights of the bristles 31 are sequentially increased from the inner ring to the outer ring to be matched with the spherical surface of the rotary filter ball 2.

During the use, be equipped with the utility model discloses a take out silt pipe 1 and insert suction silt water slurry in the silt pond, bars cover 4 has blockked thick debris in the silt pond.

In the pumping process, because the silt pumping pipe 1 has water flow, when the water flow flows through the rotary type filter ball 2, the water flushing impeller is driven to rotate, so that the rotary type filter ball 2 integrally rotates, even if silt is adhered to the spherical surface of the rotary type filter ball 2 and blocks the individual through hole 24, the acting force direction of the water on the silt is changed due to the rotation of the rotary type filter ball 2, and the silt can fall off under the combined action of the rotating centrifugal force.

To pasting stronger silt piece, owing to set up ring brush 3, also can make silt piece drop from rotary type filter ball 2. Due to the triple anti-blocking design, the suction port is guaranteed not to be blocked.
