Self-control fish feed feeding device capable of reducing pollution for reservoir

Abstract

The invention discloses a self-control fish feed feeding device capable of reducing pollution for a reservoir. The device comprises a main body box, wherein a lifting cavity with a downward opening isformed in the main body box; an annular floating block positioned on the outer side of the lifting cavity is fixedly connected to the lower end face of the main body box; a waste through cavity is communicated with the left side of the lifting cavity; a waste cavity is communicated with the left side of the waste through cavity; and a feeding box which can be slidably and cooperatively connectedwith the lifting cavity is arranged in the lifting cavity. Through the design of the liftable feeding box, the feeding box is positioned on the upper side of the water surface during non-feeding time,the situation is avoided that feed is soaked in water for a long time and accordingly water eutrophication is caused, and meanwhile the situation can also be avoided that feed precipitation is causedby direct feeding; and after feeding is completed each time, waste is scraped off through a scraping plate, whether or not the waste is left is judged through a contact sensor, accordingly the heightof an abutting plate is adjusted, the feeding amount of the next time is adjusted, the feeding amount is adjusted in real time, and the situation is avoided that the feeding amount is too large or too small due to fish flow.

Description

technical field [0001] The invention relates to the related technical field of water conservancy engineering, in particular to a self-controlling fish feed feeding device for reservoirs that can reduce pollution. Background technique [0002] When raising fish in a reservoir, due to the large water surface of the reservoir, it is difficult and costly to put fish feed on a regular basis for fine farming. At the same time, the fish in the reservoir are highly mobile, and the number of fish in the same area will change at different times. Quantitative feeding may Due to the change in the number of fish, too much feed will lead to waste of feed sedimentation or too little feed will lead to insufficient nutrition of fish. At the same time, excessive fish feed soaked in water for a long time will pollute the water body and lead to the possibility of eutrophication of the water body. On the one hand, the precipitated feed will also block the water outlet of the reservoir. Content...
