A device for removing excrement at the bottom of a fish tank

Abstract

The invention discloses a device for removing excrement at the bottom of a fish tank, comprising a fish tank, a partition net is laid in the fish tank, a device plate is fixedly connected between the partition net and the inner bottom of the fish tank, and an oxygen pump is placed on the upper end of the partition net Air stone, the device plate is provided with a device chamber, the inner bottom of the device chamber is rotatably connected with a rotating shaft, the lower end of the rotating shaft is fixedly connected with a cam, and the upper end of the rotating shaft penetrates through the partition net and the oxygen pump air stone and is fixed An impeller is connected, and the impeller is located directly above the gas stone of the oxygen pump. A cavity is provided on one side of the device cavity, and the cavity is divided into a first cavity and a second cavity by a piston. The piston The side wall of the side wall is fixedly connected with a resisting rod extending into the device cavity, and the end side wall of the resisting rod is fixedly connected with a limiting plate. The invention has a reasonable structure and can cleverly use the power of the oxygen pump as a driving source to automatically realize the cleaning of pollutants at the bottom of the fish tank.

Description

technical field [0001] The invention relates to the technical field of fish tanks, in particular to a device for removing excrement at the bottom of the fish tank. Background technique [0002] Fish tank, a kind of water tank containing live fish, the tank body is transparent, mostly made of glass, and can also be used to raise tropical fish or goldfish for ornamental purposes. The fish tank is not only the home of the fish, but also the life enjoyment of the family. The flawless double-layer float glass not only creates a warm home for the fish, but also ensures the safety of the overall living environment. [0003] Due to the closed nature of the fish tank, the water in the tank cannot be effectively circulated. In this environment, fish farming, food residues and fish excrement cannot be discharged, resulting in the deterioration of the water quality in the breeding tank and the imbalance of pH, which will cause the fish in the tank. The water is seriously polluted, and...

Problems solved by technology

[0003] Due to the closed nature of the fish tank, the water in the tank cannot be effectively circulated. In this environment, fish farming, food residues and fish excrement cannot be discharged, resulting in the deterioration of the water quality in the breeding tank and the imbalance of pH, which will cause the fish in the tank. The water is seriously polluted, and over time it may even cause the death of fish in the pool

[0004] At present, filters are generally used to filter fish tanks, but they can only filter out impurities in the water body. Most of the food residue and excrement will settle at the bottom of the fish tank and cannot be filtered. Only the water can be completely poured out to clean up. trouble
