Abstract

The invention discloses an automatic water change system for fresh-water fish breeding. The automatic water change system comprises a breeding pond, a water inlet pipe and a blow-off pipe, wherein theupper end of the inner side wall of the breeding pond is provided with an overflow pipe, the middle-lower portion of the inside of the breeding pond is provided with a breeding net, the side wall ofthe breeding net is provided with a water inlet pipe, the water inlet pipe is provided with a water pump, the end, close to the breeding pond, of the water inlet pipe is provided with a flow detector,one side of the flow detector is provided with a water inlet control valve, the lower end of the inner wall of the breeding pond is provided with an aeration pipe, the lower end of the inner wall ofthe breeding pond is provided with a row of ultrasonic oscillators, and the lower end of the inner wall of the breeding pond is provided with a flushing spray head. The automatic water change system has the advantages that the cleanliness situation of the water in the breeding pond can be automatically detected, oxygen content regulation or water change can be performed according to water quality,dredging operation can be automatically performed during water change, it is ensured that pond water is clean and hygienic, the automation degree is high, manual operation is decreased, and convenience is provided for management.

Description

technical field [0001] The invention relates to the technical field of freshwater aquaculture, in particular to an automatic water exchange system for freshwater fish aquaculture. Background technique [0002] Fish meat is tender, delicious and nutritious, and it is a good source of some vitamins and minerals. With the improvement of people's living standards, people's demand for fish meat is also increasing. In order to meet market demand, many people start freshwater fish farming. The culture of freshwater fish is mostly carried out in fish ponds or special fish ponds. These places generally use stagnant water. In order to ensure the normal growth of fish, it is necessary to add oxygen to the water regularly. Due to the impact of fish food and fish feces, the water quality in the fish pond will gradually deteriorate, and in severe cases, the fish will die. In order to ensure the normal growth of fish, the water needs to be replaced regularly. At present, the staff of fis...

Problems solved by technology

Due to the influence of fish food and fish feces, the water quality in the fish pond will gradually deteriorate, and in severe cases, the fish will die. In order to ensure the normal growth of fish, the water needs to be replaced regularly

At present, fish farming staff mainly judge whether to change the water through subjective judgment, and subjective judgment is prone to errors, resulting in the death of fish, and the water quality needs to be checked frequently, which is time-consuming and laborious
