Embodiment

[0018] This embodiment is specifically described through the experimental simulation in the design process of the culture pond. The side length of the simulated culture pond is 6420 mm, the thickness of the pond wall is 100 mm, and the depth of the center of the pond bottom is 1500 mm.

[0019] Such as figure 1 , figure 2 The shown shows a culture pond for excreting metabolites and residual bait by water movement, including a culture pond 1 , a water inlet main pipe 2 , a water inlet branch pipe 3 , and a double-layer return pipe 4 . Embodiment Build 4 groups of culture ponds, each group includes two culture ponds, the shape is three-dimensional inverted circular arc rectangle, the bottom is conical, the culture pond side length is 6420mm, and the arcs around are π / 2. The water inlet main pipe 2 is installed above the breeding pond, and the water inlet main pipe includes two water inlet branch pipes 3, and the two water inlet branch pipes 3 extend from the two ends of the w...

specific Embodiment 1

[0020] The first group of culture ponds were built according to the above method, and the center slope of the bottom of the three culture ponds was controlled to be 0.03. By adjusting the water inlet speed of the water inlet branch pipe, the surface water body rotation of the culture pond was controlled at about 1.4m / s. However, the length of the arc angle around the first breeding pool of this group is 1 / 4 side length, the arc length around the second culture pool is 1 / 6 side length, and the arc length around the third culture pool is 1 / 4 side length. 1 / 8 side length. After the flow rate of the water body was measured at 1.4m / s by the current meter, the residual bait was sprinkled into the two groups of culture ponds, and the residual bait was distributed evenly in the water body as much as possible. After spreading, start to measure the time for the residual bait in the two breeding ponds to gather to the bottom of the middle of the breeding pond (a small amount of residual ...

specific Embodiment 2

[0022] Build the second group of culture ponds according to the above method, and the third group of culture ponds has 3 experimental ponds in total. The arc angle and arc length around the two culture ponds are controlled to be 1 / 6 side length, and the culture is controlled by adjusting the water inlet speed of the water inlet branch pipe. The water velocity on the surface of the pool is about 1.4m / s. But the bottom center slope of the first culture pond of this group is controlled to be 0.03, the bottom center slope of the second culture pond is controlled to be 0.04, and the bottom center slope of the second culture pond is controlled to be 0.05. After the flow rate of the water body was measured at 0.4m / s by the current meter, the residual bait was sprinkled into the two groups of culture ponds respectively, and the residual bait was distributed evenly in the water body as much as possible. After spreading, start to measure the time for the residual bait in the two breedin...

Abstract

The invention discloses a culture pond capable of draining metabolites and residual feed by means of water flow movement. The culture pond comprises a culture pond body, wherein the culture pond body is in a shape of a three-dimensional rectangular pond, four corners of the three-dimensional rectangular pond are arc-shaped, and the bottom is in a shape of a conical pot bottom with the deep middle and two shallow sides; a double-layer water return pipeline is mounted in the center of the culture pond body; a main water inlet pipe is mounted on one side above the culture pond body and comprises two water inlet branch pipes, the two water inlet branch pipes extend to two opposite corners below the water surface of the culture pond body from two ends of the main water inlet pipe and have different extension heights, opposite water injection directions and the identical water injection speed, and the rotating speed of the surface water body of the culture pond body is controlled to be in a range of 0.4-2.0 m / s by adjusting the water injection speed of the water inlet branch pipes. The culture pond is designed for drainage of the feed by using the effect of the rotating centripetal force and the tea leaf paradox principle, the feed is drained by integrating three factors including the radian, the bottom gradient and the water velocity of the culture pond, and water in the pond body is driven by the two water inlet branch pipes extending into the pond body to form micro vortex flow, so that the feed is drained timely.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a culture pond for excreting metabolites and residual bait by using water flow movement. Background technique [0002] In modern intensive fish farming ponds, metabolites and residual baits in the ponds need to be cleaned or discharged regularly to avoid affecting water quality. There are two main methods for cleaning metabolites and residual bait in the existing breeding technology. One is to install a baffle at the water outlet of the breeding pond 50cm away from the edge of the pond. The pool wall fits and fixes, and there is a gap between the bottom and the bottom of the pool. A conical sewage collection pool is built at the rear of the breeding pool, and sewage pipes and valves are installed at the bottom of the sewage collection pool. Underflow is formed at the bottom of the pond, and the sediment at the bottom of the culture pond is sucked into the baffle with the ...
