Aquarium bottom excrement removing device

Abstract

The invention discloses an aquarium bottom excrement removing device, comprising an aquarium; a partition net is laid in the aquarium; a device plate is fixedly connected between the partition net andthe inner bottom of the aquarium; an oxygen pumping stone is placed at the upper end of the partition net, and a device cavity is arranged in the device plate; a rotating shaft is rotatably connectedto the inner bottom of the device cavity, and a cam is fixedly connected to the lower end of the rotating shaft; the upper end of the rotating shaft penetrates the partition net and the oxygen pumping stone and is fixedly connected with a blade wheel; the blade wheel is positioned right above the oxygen pumping stone, and one side of the device cavity is provided with an empty cavity; the empty cavity is divided into a first cavity and a second cavity through a piston; the side wall of the piston is fixedly connected with an abutting rod extending into the device cavity; and the end side wallof the abutting rod is fixedly connected with a limiting plate. The aquarium bottom excrement removing device is reasonable in structure, power of the oxygen pump can be skillfully utilized as a driving source, and pollutants at the bottom of the aquarium can be automatically removed.

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
