Novel crab culturing structure

Abstract

The invention relates to a novel crab culturing structure. The novel crab culturing structure comprises a left surface, a right surface, a back surface, a front surface and a bottom surface, wherein the bottom surface is closely combined together with the left surface, the right surface, the back surface and the front surface to form a closed inner space; the bottom surface of a box is in the shape of a bucket or a cone consisting of a plurality of surfaces and forms an inclination angle of 1-45 degrees with the horizontal surface; a water inlet pipe and a double-layer water outlet pipe are arranged in the closed inner space; and the water inlet pipe is clamped in one pair of grooves on the left surface and the right surface. The bottom of the novel crab culturing structure provided by the invention is in inclined design to ensure that submerging pollutants can quickly flow to the lower side of the double-layer water outlet pipe under double actions of water flow and gravity, and a ring-shaped groove is formed at the lower side of the double-layer water outlet pipe to ensure that the pollutants can be collected and concentrated more efficiently and discharged out of a culture box quickly and completely, so that the cleanliness of the culture box is kept, the quality of a water environment for culturing crabs is improved, and better economic benefits can be created.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a novel crab breeding structure. Background technique [0002] The structure proposed by the original "a new type of crab breeding structure" patent "ZL201220024095.7" has a flat bottom of the box, and the submerged pollutants cannot be discharged quickly, resulting in the accumulation of residual bait and feces in the box during the breeding process. This leads to an increase in the concentration of ammonia nitrogen and nitrous acid in the water. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and proposes a new type of crab breeding structure, so that the submerged pollutants at the bottom can quickly flow to the bottom of the double-layer outlet pipe with the dual effects of water flow and gravity. An annular groove enables pollutants to be collected and concentrated more effectively, and is quickly and ...
