Technical Field

The utility model belongs to the technical field of the aquaculture technique and specifically relates to a temporary rearing pond and be provided with the above-mentioned temporary rearing system of temporary rearing pond.

Background

The existing temporary rearing ponds are as follows:

firstly, the temporary culture pond is integrally built by waterproof canvas, the temporary culture pond is convenient to build, disassemble and store, but the temporary culture pond is low in overall rigidity and easy to collapse;

secondly, the temporary culture pond is integrally made of polypropylene or polyvinyl chloride materials, and the temporary culture pond has enough rigidity compared with a temporary culture pond built by canvas, but cannot be enlarged in the temporary culture pond, so that the temporary culture pond is difficult to be suitable for medium-large culture;

thirdly, the temporary culture pond is integrally cast by concrete, and although the temporary culture pond has enough rigidity compared with the second temporary culture pond and can be suitable for medium and large-scale culture, the temporary culture pond is higher in integral construction cost;

fourthly, the wall of the temporary culture pond is made of polypropylene or polyvinyl chloride materials, the bottom of the temporary culture pond is formed by pouring concrete, and the bottom of the temporary culture pond is wrapped at the lower part of the wall of the temporary culture pond and forms a culture cavity with the wall of the temporary culture pond.

In the second to fourth temporary rearing ponds, a fish outlet may be formed at the bottom of the temporary rearing pond, and a gate may be formed at the fish outlet to open or close the fish outlet, wherein the fish outlet is provided to facilitate discharging fish from the temporary rearing pond. However, the present breed chamber bottom surface of breeding the pond temporarily all is the plane setting, lead to when unloading the fish to have a small part fish and water to remain on the bottom surface of breeding the chamber for need the manual work to clear out remaining fish from breeding the pond temporarily and need the manual work to clean remaining water and dirty filth (like the excrement of fish, fish scale, leaf etc.), increased raiser's work load, and when breeding remaining water and dirty filth in the intracavity and not in time clearing up, still breed the bacterium easily, the mosquito and give off the stink easily.

Disclosure of Invention

In order to solve the problems, the main object of the utility model is to provide a temporary rearing pond convenient to arrange fish, water and dirty filth in the pond to the greatest extent.

Another object of the utility model is to provide a system of raising temporarily that is provided with the above-mentioned pond of raising temporarily.

In order to realize the utility model discloses a main objective, the utility model provides a temporary culture pond, including cell body and gate, the cell body has the breed chamber, and the cell body is being provided with out the fish mouth in the bottom department that is close to self, and the gate setting is in a fish mouth department, and the gate can be opened or seal out the fish mouth, and wherein, the first bottom surface of breeding the chamber is the conical surface setting, and the conical surface is the bottom protrusion towards the cell body, and the cell body is provided with out the fish groove in the below of conical surface, and the second bottom surface that goes out the fish groove inclines towards a fish mouth from the summit department of conical surface and extends, and goes out fish groove intercommunication and breed the chamber and go out.
