Mechanism for rapidly removing sediments in culture pond

The invention relates to a mechanism for quickly removing sediments in a culture pond, which comprises a sewage collecting pond and a sewage discharge channel, the sewage discharge channel extends left and right and is arranged below the sewage collecting pond, the sewage discharge channel is provided with a gap which is consistent with the extending direction of the sewage discharge channel and is communicated with the bottom of the sewage collecting pond, and the left end of the sewage discharge channel extends to the outside to form a sewage discharge port; the bottom surface of the sewage collecting tank is an inclined surface of which the side edge inclines towards the gap; a channel communicated with the bottom of the culture pond is also arranged in the bottom of the sewage collecting pond. The sewage collecting tank is used for temporarily storing the sediments such as the breeding water and the excrement, so that the sediments such as the excrement can be concentrated and gathered (temporarily remain
