Technical Field

The invention relates to the technical field of shellfish culture, in particular to a full-automatic microalgae feeding device system suitable for shellfish culture.

Background

The sea water floating raft hanging cage type shellfish culture is one of the main modes of shellfish culture at present, namely, artificially cultured shellfish seedlings are arranged in a net cage according to a certain density proportion, an appropriate distance and a water layer are selected according to culture varieties and water quality conditions of a culture area, and the net cage is hung on a floating raft arranged on the sea to be cultured. However, with the increase of shellfish demand, the culture area is continuously enlarged, the arrangement density of the floating rafts is continuously increased, the content of microalgae in natural seawater is low, the ingestion demand of high-density cultured shellfish cannot be met, and a large amount of artificial bait feeding is needed for improving economic benefit. On the one hand, the water pollution of the culture area is serious, and the ecological environment of the nearby marine area is unbalanced; on the other hand, the death rate of the cultured shellfish is continuously improved, and economic loss is caused to related culture enterprises. In addition, the artificial bait feeding for shellfish culture in the past is complex, the culture depth is limited, and the development requirement of shellfish culture is limited.

Further, energy supply device is solar cell panel, and solar cell panel is connected with the centrifugal pump electricity. Adopt solar cell panel to make things convenient for the offshore operation for the centrifugal pump energy supply, avoided being not convenient for power transmission because of floating platform is too far away from the coast.

Furthermore, the bottom of the supporting tube is provided with a rotary actuator, and the top of the supporting tube is rotatably connected with the floating platform.

Further, the rotary actuator comprises a plurality of force bearing plates which are uniformly arranged at the bottom of the supporting tube in the circumferential direction.

As shown in fig. 1 to 3, a fully automatic microalgae feeding system suitable for shellfish culture comprises: the device comprises a floating platform 1, wherein a microalgae incubator 2 is arranged on the floating platform 1, a support tube 3 is connected to the bottom of the floating platform 1, and a plurality of Venturi assisted algae sprayers 4 are connected to the outer wall of the support tube 3 from top to bottom; the venturi assisted algae spraying device 4 comprises a venturi tube 41, a microalgae nozzle 42 is arranged in the venturi tube 41, the microalgae nozzle 42 is communicated with the microalgae incubator 2 through a pipeline 43 arranged in the support tube 3 and a centrifugal pump 5 arranged on the floating platform 1, and an energy supply device for driving the centrifugal pump 5 to work is arranged on the floating platform 1. The energy supply device is a solar cell panel 6, and the solar cell panel 6 is electrically connected with the centrifugal pump 5 through a circuit control system.

The bottom of the supporting tube 3 is provided with a rotary actuator 7, and the top of the supporting tube 3 is rotatably connected with the floating platform 1 through a bearing 8.

The rotary actuator 7 comprises a plurality of force-bearing plates which are uniformly mounted circumferentially at the bottom of the support tube 3. The rotary actuator 7 can realize 360-degree rotation of the supporting tube 3, and the stress plate drives the supporting tube 3 to rotate under the action of seawater flow, so that 360-degree feeding is realized.

The inlet section 44 of the venturi tube 41 is disposed downward, the diffuser section 45 of the venturi tube 41 is disposed upward, and the throat 66 of the venturi tube 41 is connected and fixed to the support tube 3 via the connection pipe 47. The throat 66 is provided with a sealing plug 48 at the connection part 47, and the sealing plug 48 wraps the pipeline 43. The microalgae nozzle 42 is conical and is arranged upwards, and the outer diameter of the upper end of the microalgae nozzle 42 is smaller than that of the lower end.

Under the working state: the solar cell panel 6 supplies energy to the centrifugal pump 5, and the centrifugal pump 5 pumps microalgae in the microalgae incubator 2 and transmits the microalgae to the microalgae nozzle 42, and the microalgae is diffused and sprayed out under the action of the venturi tube 41. Meanwhile, the support pipe 3 is driven by the rotary actuator 7 to rotate, so that the Venturi assists in spraying the algae by rotating the algae sprayer 4 in the circumferential direction.

The working principle is as follows: the algae liquid in the microalgae incubator 2 is conveyed to the microalgae nozzle 42 through the pipeline 43 in the supporting pipe 3, and the microalgae nozzle is acted by gravity G-mg and simultaneously needs to overcome the pressure P-rho of the seawater_{Seawater, its production and use}ghs, and the potential gravitational energy mgh ═ ρ of the algae liquid in the pipe 43 actually_{Algae liquid}ghs are consistent with the opportunity for seawater pressure to be overcome, where p_{Algae liquid}Slightly larger than rho_{Seawater, its production and use}But the difference is not much, and the two are considered to be consistent (wherein h is the height of the algae liquid in the pipeline 43, and s is the cross-sectional area of the algae transporting pipe, i.e. the cross-sectional area of the pipeline 43). After the centrifugal pump 5 provides a certain power for the algae liquid in the pipeline 43, the algae liquid with a certain initial speed can be easily conveyed to the microalgae nozzle 42 through the pipeline 43. The microalgae nozzle 42 is conical, and the initial microalgae spraying speed is further increased by using the Bernoulli principle and in a mode of reducing the area of a spraying opening.

As shown in FIG. 3, the external venturi 41, again using the Bernoulli principle, i.e. the venturi isFirst, the height h of the inlet section 44 of the venturi 41₁A height h lower than the microalgae nozzle 42₂The static pressure at the inlet section 44 of the venturi 41 is greater than the static pressure at the microalgae nozzle 42, i.e. ρ_{Seawater, its production and use}gh₁＞ρ_{Algae liquid}gh₂(ii) a Secondly, the microalgae liquid jetted from the microalgae nozzle 42 has a certain initial velocity v₂The inlet section 44, which is much larger than the venturi 41, may beProvided velocity v₁From the "fundamental principle of large velocity and small pressure", the dynamic pressure at the inlet section 44 of the venturi 41 is much higher than that at the microalgae nozzle 42, i.e. the dynamic pressure is greaterMeanwhile, because the temperature of the algae liquid conveyed to the microalgae nozzle 42 by the pipeline 43 is higher than the temperature of the seawater, the pressure at the microalgae nozzle 42 above the throat 66 is far lower than the pressure at the inlet section 44 of the venturi tube 41, namely P₂<<P₁. Therefore, the algae liquid delivered to the microalgae nozzle 42 by the pipeline 43 is smoothly ejected by the pressure difference between the inlet section 44 of the venturi tube 41 and the pressure of the microalgae nozzle 42. In the process, an ideal injection effect can be achieved without an additional power source.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
