Rice field cultured fish circulating drain valve

Abstract

The invention discloses a rice field cultured fish circulating drain valve. The rice field cultured fish circulating drain valve comprises a shell; a drainage cavity is formed in the shell, a buoyancychamber is formed in the drainage cavity, a buoyancy ball is arranged in the buoyancy chamber in a sliding mode, a buoyancy sliding block is arranged in the buoyancy chamber in a sliding mode, a buoyancy connecting rod is fixedly arranged at the upper end of the buoyancy sliding block, an adjusting connecting rod is fixedly arranged on the buoyancy connecting rod, an adjusting rod is fixedly arranged on the adjusting connecting rod, and a rotating wheel is fixedly arranged on the adjusting rod. According to the intelligent water valve, nursing of farmers on a rice field can be reduced, fish culture in the rice field is not burdened any more, when the water surface is too high or rainstorm occurs, the water valve is opened, a pipeline is enlarged, water in the rice field is rapidly drained, when the water level is too low, a water pump is started, water in a water storage chamber is pumped into the rice field, the water valve is closed, outflow of water in the rice field is reduced, anautomatic cleaning device can effectively clean weeds and sewage in front of the water valve, and the water outflow efficiency is improved.

Description

technical field [0001] The invention relates to the field of water conservancy gates, in particular to a circular drainage valve for fish farming in paddy fields. Background technique [0002] As we all know, fish farming in paddy fields can effectively improve the economic benefits of fish farming and rice planting, and it is widely promoted now. Fish farming in paddy fields needs to control the amount of water. When the water level in the paddy field is too high, the rice will die and the fish will jump away. If it is too low, fish will die, and weeds and sludge are easy to accumulate in the paddy field, which will block the water valve. Therefore, it is necessary to design a device that can automatically adjust and control the water level in the paddy field and replenish water in time. Contents of the invention [0003] The purpose of the present invention is to provide a rice field cultured fish circulation drain valve for overcoming the above-mentioned defects in the ...
