Fishpond safety protection device

Abstract

The invention discloses a fishpond safety protection device and belongs to the field of aquaculture. An annular floating body sleeves in the vertical direction of the L shape of a water outgoing pipe, a water outgoing hole is formed in an inner ring face, a water incoming hole is formed in one side of a lower face, and an inner communicating pipe connecting the water incoming hole with the water outgoing hole is arranged in a buoyancy cavity; a sealing ring is matched with the outer surface in the vertical direction of the L shape of the water outgoing pipe to enable the annular floating body to slide in the vertical direction of the L shape of the water outgoing pipe or matched with the inner ring face to enable the annular floating body to slide on a sealing ring mounted in the vertical direction of the L shape of the water outgoing pipe and can open or close a drainage channel when sliding up and down. The fishpond safety protection device is compact and reasonable in structure, convenient to manufacture and use, high in safety protection capability and automation level and good in effect on automatically draining water and maintaining water level in a fishpond; a person is not needed for guarding during automatic draining, the draining channel is automatically closed to maintain the water level when the water level in the fishpond is lower than a set breeding water level, and the fishpond safety protection device is necessary equipment for safety protection and automated management of the fishpond.

Description

technical field [0001] The invention relates to a fish pond safety protection device in the field of aquaculture. Background technique [0002] When it rains heavily, the water in the fish pond soars and causes the water in the fish pond to turn over from the ridge, washing away the fish cultured in the fish pond, and often washes down the ridge of the fish pond, causing damage to the cultured fish. Farmers have suffered enormous losses. In order to ensure the safety of fish pond farming, we have invented a device that can automatically protect the safety of fish ponds after long-term research. Contents of the invention [0003] The purpose of the present invention is to provide a device that can automatically manage and maintain the water level in the fish pond and protect the fish, shrimps, crabs, etc. cultured in the fish pond from being washed away by the heavy rain, and can automatically discharge excessive rainwater in the fish pond. Environmental protection safety...
