Automatic water replenishing device for fries

Abstract

The invention discloses an automatic water replenishing device for fries. The automatic water replenishing device comprises a fishpond, a certain amount of water is arranged in the fishpond, a water replenishing pipe is arranged on one side of the fishpond, a gear control disc is arranged on one side of the water replenishing pipe, a chain is arranged on the gear control disc, and the chain and the gear control disc are matched with each other. A water level buoy is arranged at one end of the chain and suspends on the water surface in the fishpond, a meta block is arranged at the other end ofthe chain, a rotary shaft is arranged in the middle of the gear control disc and arranged in the water replenishing pipe, a gear is arranged at the end of the rotary shaft, and a push plate matched with the gear is arranged in the water replenishing pipe. A gear rack is arranged on the push plate, the gear rack is meshed with the gear, and the end of the push plate is connected with a water stop plate. A rotating shaft is arranged in the middle of the water stop plate, and the rotating shaft is arranged on the water replenishing pipe. According to the automatic water replenishing device, the gear control disc is controlled to rotate through the metal block and the water level buoy, the push plate is controlled to rotate the water stop plate, the fishpond can be replenished with water conveniently, automatic operation is achieved, and manual operation is not needed.

Description

technical field [0001] The invention relates to the technical field of fry breeding, in particular to an automatic water replenishment device for fry. Background technique [0002] The growth of fish has very strict requirements on the surrounding environment. It not only needs normal food requirements, but also correlates with physical and chemical indicators such as water quality, dissolved oxygen, biochemical oxygen demand, temperature, and light. As a professional breeding place, fish ponds must observe various indicators every day and adjust them in time to achieve the optimal growth environment. However, due to the heavy production tasks and various indicators, the changes of certain indicators are often neglected, which will affect the growth of fish in serious cases, and then affect the benefits; [0003] The water storage capacity of the fish pond is a very important indicator. With the biological consumption and evaporation, the water volume will continue to decre...

However, due to the heavy production tasks and various indicators, the changes of certain indicators are often neglected, which will affect the growth of fish in serious cases, and then affect the benefits;

[0003] The water storage capacity of the fish pond is a very important indicator. With the biological consumption and evaporation, the water volume will continue to decrease over time, resulting in a decrease in the activity space of the fish, and with the increase of metabolites, the salt concentration will increase. , will affect the growth of organisms, therefore, a constant amount of water is very necessary for aquaculture, but the existing water replenishment for fish ponds generally uses artificial water replenishment, but artificial water replenishment cannot be accurately replenished, and cannot be replenished in real time, and for large fish ponds , fish ponds increase the labor load of workers more, for this reason the present invention proposes a kind of fish fry automatic water supply device to be used to solve the above-mentioned problem
