Heat-preservation crab pond

Abstract

The invention discloses a heat-preservation crab pond which comprises crab ponds and heat-preservation devices, wherein the crab ponds comprise a first crab pond, a second crab pond and a third crab pond; the first crab pond is arranged on the ground; the second crab pond is connected with the ground through first support columns; the third crab pond is connected with the ground through second support columns; and the heat-preservation devices are positioned on the second crab pond and the third crab pond. The crab ponds can be supported in air through support plates, so that the breeding areaof crabs is increased, a relatively large amount of crabs can be bred conveniently for farmers, in addition, each crab pond can have sufficient sunshine, and the benefits of users can be increased; the support columns of the crab ponds can be freely prolonged or shrunk and can be conveniently adjusted by users; in addition, tubes are arranged inside the support columns, so that water can be conveniently fed into the crab ponds; and the heat-preservation devices are arranged inside both the second crab pond and the third crab pond, the temperature of water inside the crab ponds can be conveniently controlled according to demands of users, and a good living environment can be provided for crabs.

Description

technical field [0001] The invention relates to a freshwater culture pond, in particular to a crab pond capable of heat preservation. Background technique [0002] Crabs are rich in protein and trace elements, which have a good nourishing effect on the body. Crabs are known as "gutless men". Although they are small in size, they have all five internal organs. In recent years, more and more people keep crabs as pets, and they pay more and more attention to crabs.

The bristles are long and dense. Hairy ...
