Sewage drainage mechanism of fishpond cleaning system

Abstract

The invention discloses a sewage drainage mechanism of a fishpond cleaning system. The sewage drainage mechanism comprises a fishpond, a pond bottom of the fishpond is in a funnel shape, a sewage drainage port is formed in the pond bottom of the fishpond, a sewage drainage valve is installed on the sewage drainage port, and a driving mechanism is installed on the sewage drainage valve; the sewagedrainage valve comprises a valve body and a valve lid; the valve lid is rotatably fixed to the valve body; the valve body is further provided with a limiting block to control the maximal opening angleof the valve lid to be smaller than 90 degrees. According to the sewage drainage mechanism, the sewage drainage valve is arranged at the funnel-shaped pond bottom and communicated with the outside through a sewage drainage pipeline, so that the sewage drainage speed is high and the sewage drainage effect is good; besides, through the cooperation of an air cylinder / oil cylinder, a pulley and a traction rope, the valve lid of the sewage drainage valve is opened and closed conveniently; through limiting of a limiting plate, the opening angle of the valve lid is smaller than 90 degrees to avoid the situation that the opening angle is too large and a user cannot close the valve lid by himself / herself.

Description

technical field [0001] The invention relates to the technical field of fish pond management, in particular to a sewage discharge mechanism of a fish pond cleaning system. Background technique [0002] If the fish pond is not cleaned for a long time, the silt at the bottom of the fish pond will be thicker, the effective water storage depth of the pond will become shallower, the capacity of the water body will decrease, the living space of aquatic products will be reduced, and the fish output will be reduced. The silt contains a large amount of organic matter, which is oxidized and decomposed under the action of microorganisms, continuously consuming a large amount of dissolved oxygen in the water body, aggravating the "oxygen debt" of the pond, causing fish to float, and even turning over the pond. The nitrogen-containing and sulfur-containing organic matter in the sludge is decomposed (inorganized) by bacteria under anoxic conditions, and some reduced intermediate products (...

AI Technical Summary

Problems solved by technology

[0003] However, due to the large area of ​​the fish pond, the large amount of water storage, and the variety of fish raised in the pond, the cleaning of the fish pond is complicated. Most of the mud in the pond is cleaned manually. The work efficiency is low, time-consuming and labor-intensive, and affects the normal use of the fish pond.
