Description

Bubble diversion type jellyfish display system

Technical Field

The invention belongs to the technical field of aquatic animal breeding display equipment, and particularly relates to a bubble diversion type jellyfish display system.

Background

The coastal hydrozoan jellyfishes in China are rich in variety, attractive in appearance and various in breeding mode, and the demand of aquariums for long-term popular science display of the jellyfishes is higher and higher. Compared with the pot jellyfish, the individual jellyfish of Hydra is small, the diameters of various umbrellas are only a few millimeters, after the individual jellyfish is impacted and deformed by water flow through a pipeline, a 60-mesh grid net can be passed through, in the feeding work, the mode that a water pump is used for directly spraying water flow to circulate in the traditional mode is changed, and a bubble diversion mode is used, so that the feeding water body which is more stable and has excellent water quality is obtained. The jellyfish breeding has higher requirement on water quality, and the water body circulating and filtering effect cannot be ensured only by using bubble flow guiding, so that the invention adopts an internal circulating and external circulating and overlapping mode, ensures stable water flow and obtains more excellent water body physicochemical property.

The existing jellyfish display cylinder is generally a cylinder body with a transparent front wall, a smooth cylinder body and a circulating system, and cannot be used for displaying small jellyfish of Hydra and jellyfish larva of potted Hydra. At present, the method for displaying the jellyfishes generally utilizes the jellyfishes cultured in the back field to be continuously supplemented, the operation is troublesome, the survival rate of the jellyfishes is low, and the display effect is poor, so that the number of venues capable of displaying the jellyfishes is small, and the popularization and the appreciation of the jellyfishes are influenced.

The invention also provides a using method of the system, wherein the water flow running direction in the system is as follows: the water flow in the internal circulation cylinder runs anticlockwise, and the water flow in the external circulation cylinder runs clockwise. The external water flow enters from the water inlet of the external circulation cylinder, the water flow keeps running clockwise at a high speed, and the additional water flow in the internal circulation cylinder enters the external circulation cylinder from the internal circulation cylinder through the gap between the flow guide grooves of the internal intermediate body and enters the circulating and filtering system connected with the external circulation cylinder through the water outlet of the external circulation cylinder by virtue of the Bernoulli effect. In the upper half part of the external circulation cylinder, namely the part above the water outlet, the water flow is slower, and the speed is kept lower; through the water flow of the internal circulation cylinder, partial water flow above the external circulation cylinder is guided into the internal circulation cylinder from the side wall opening of the internal intermediate body, so that the water body exchange of the internal circulation cylinder and the external circulation cylinder is completed, and the cultured jellyfishes are taken and placed through the opening of the internal intermediate body.

Compared with the prior art, the invention has the beneficial effects that:

the system is used for displaying the jellyfishes, the jellyfishes are placed into the internal circulating cylinder, the stable water quality is ensured through the water body circulating filtration of the external circulating cylinder, the water flow direction of the external circulating cylinder is opposite to that of the internal circulating cylinder, the water body exchange effect of the external circulating cylinder and the water body exchange effect of the internal displaying cylinder are enhanced through the Bernoulli effect, and the stable water quality of the water body of the internal circulating cylinder is ensured.

The system is mainly used for displaying jellyfish varieties such as polyp jellyfish larva and the like, the water body convection effect of the external circulation cylinder and the internal circulation cylinder is obvious, the water flow of the internal display cylinder is stable, the stimulation to the displayed jellyfish is small, the physicochemical property of the internal water body is stable, and the condition that the small jellyfish is directly impacted by the water flow to cause animal damage caused by the common water flow circulation cylinder is avoided. The feeding effect is greatly improved compared with the conventional method.
