Embodiment 1

[0019] Example 1, see Figure 1 to Figure 2 , a fish pond with automatic sewage function, comprising a fish pond body 1, the bottom of the fish pond body is provided with a sewage outlet 2; the fish pond body is divided into a fish farming activity unit 110 and a sewage discharge unit 120, the above-mentioned fish farming activity unit The height is not less than 1 / 2 of the height of the fish pond body; if the height is not enough, it will cause more sewage discharge on the one hand, and on the other hand, the density of fish will be too high during the cleaning process, resulting in hypoxia; between the fish farming activity unit and the sewage unit Plane net 130 is provided; the order number of plane net can be selected according to the kind, the size of actual cultured fish, also will meet the smooth passage of residual bait and excrement in addition; The sewage unit is divided into a retractable shielding mechanism 140 of independent chambers; its purpose is to use the shi...

Embodiment 2

[0025] Example 2, see Figure 4, the retractable shielding mechanism 140 can also adopt the following scheme, including the first slideway 141 fixed on the side wall of the fish farming activity unit in mirror image, the crossbeam 142 connecting the first slideways on both sides, and the two ends of the crossbeam Road wheels 143 are installed, and the road wheels are positioned in the first slideway and move horizontally along the first slideway; the crossbeam 142 is equipped with a submersible motor 143 that drives the crossbeam to move horizontally along the first slideway, and the submersion motor Connect one of the walking wheels 143 of the above-mentioned walking wheels through a transmission, and the submersible motor is connected to a controller that controls the opening or closing of the submersible motor; a flexible bearing plate 145 is installed on the crossbeam 142; the free end of the flexible bearing plate extends to the maintenance The upper part of the fish acti...

Abstract

The invention relates to a fishpond with an automatic sewage discharging function. The fishpond comprises a fishpond body, a sewage discharging opening is formed in the bottom of the fishpond body, the fishpond body is divided into a fish moving unit and a sewage discharging unit, a plane net is arranged between the fish moving unit and the sewage discharging unit, a retractable type shielding mechanism which can separate the fish moving unit and the sewage discharging unit into independent cavities is arranged at the bottom of the fish moving unit, and a movable horizontal sweeping mechanism is arranged at the upper portion of the sewage discharging unit. By means of the technical scheme, the fishpond body is divided into two independent cavities in an upper-lower mode by a shielding function of the shielding mechanism, dirt in the sewage discharging unit can be swept in a concentrated mode, the fish moving unit above the sewage discharging unit cannot be affected, and normal movement of fish is not affected. The dirt and water in the sewage discharging unit can be stirred by the horizontal sweeping mechanism, so that sedimentary excrement and residual feed can fully float up, sewage can be wholly discharged through the sewage discharging opening in a concentrated mode, and automatic full sewage discharging is achieved. In a sewage discharging process, a lot of aquaculture water is effectively prevented from being drained out, and water resources are saved.

Description

technical field [0001] The invention belongs to the technical field of fish pond construction, in particular to a fish pond with automatic sewage discharge function. Background technique [0002] At present, in the factory farming in our country, most of the fish ponds are cubes, and there is a drainage ditch at the bottom of the fish pond to connect the drainage outlet. The whole fish pond is a single drainage outlet. If it is completely removed, the dirt will be stored at the bottom of the pond for a long time, causing the concentration of ammonia nitrogen and nitrite in the breeding water to increase, which is extremely unfavorable to the growth of farmed fish. When it accumulates to a certain amount, it can kill the fish. [0003] With the increasing shortage of water resources, the aquaculture industry is one of the most water-consuming agriculture, and water-saving factory farming technology is imperative. Feed, etc.), circulating aquaculture, reducing evaporation and...
