Indoor culture fishpond capable of automatically collecting and discharging dirt

Abstract

The invention relates to an indoor culture fishpond capable of automatically collecting and discharging dirt, and the indoor culture fishpond comprises a main pond body and a subordinate pond body, wherein the pond bottom of the subordinate pond body is lower than the pond bottom of the main pond body; the pond bottom of the main pond body is connected with the pond wall of the subordinate pond body through a communicating pipe; a dirt discharging pipe and a reflux vertical pipe are arranged in the subordinate pond body; the inlet end of the dirt discharging pipe is arranged on the pond bottom of the subordinate pond body, and the outlet end of the dirt discharging pipe is arranged outside the subordinate pond body; a supporting frame is arranged in the subordinate pond body; a pollutant intercepting mesh sheet is arranged in the subordinate pond body above the supporting frame; the inlet end of the reflux vertical pipe is arranged in the subordinate tank body above the pollutant intercepting mesh sheet; a reflux transverse pipe is connected on the middle section of the reflux vertical pipe; the outlet end of the reflux transverse pipe is arranged in the main pond body; and an oxygen filling head is arranged in the reflux vertical pipe close to the pollutant intercepting mesh sheet. The indoor culture fishpond capable of automatically collecting and discharging the dirt disclosed by the invention is simple in structure, easy and convenient to operate, and low in manufacturing cost, and regular dirt discharging of the fishpond is changed into instant dirt discharging.

Description

technical field [0001] The invention relates to an indoor aquaculture fish pond capable of automatically collecting and discharging sewage, and belongs to the technical field of aquaculture equipment. Background technique [0002] Indoor aquaculture fish pond refers to a fish breeding place made of cement bricks in a greenhouse. It has unified heating equipment, drainage equipment and water purification equipment. It is a common fishery facility in the field of aquaculture. It is multi-purpose It is used in factory farming, fish overwintering and seed breeding, etc. [0003] Common indoor aquaculture fish ponds for seed breeding and fish overwintering are compared with factory aquaculture fish ponds, which are equipped with water purification equipment so that the aquaculture water can be recycled. However, the cost of factory farming is relatively high, and it is currently only used for the cultivation of high economic value fish such as flounder and perch, and the cultiva...

Problems solved by technology

[0004] Although indoor aquaculture fish ponds are equipped with unified drainage channels, the regular sewage discharge of fish ponds still requires manual operation, which is not only time-consuming and labor-intensive, but also sometimes causes fish disturbance and stress during the sewage discharge process of using siphon to change water. affect its feeding
