Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.

As shown in the figure 1-2, the breeding density of the parent shrimps is generally 100-200 pieces in 30-40 square, each shrimp is 50-100 g, and bait is required to be fed for 4-6 times every day, including clamworm, oyster, squid and soft pellet feed which is close to the nutrition of live bait, so that the residual bait, excrement, impurities and shrimp shells in each day need to be cleaned, and the times are generally once in the morning and at night.

The water changing process of the culture pond for the parent prawns comprises the following steps:

s1: the worker checks and starts or automatically starts the culture pond 1 for changing water within preset time;

s2: the control device 5 of the culture pond 1 receives a water changing command, sends a command to open the sewage outlet sealing cover 30, starts the sewage valve 22 to drain water, and the water level sensor 32 monitors water level information in real time and uploads the information to the control device 5;

s3: the waste water in the culture pond 1 which starts to work is slowly drained by the blowoff valve 22, and the water level of the culture pond 1 with the water level of 50-60 cm is slowly reduced to 20 cm;

s4: after the water level sensor 32 monitors that the water level is lower than 20 centimeters, the control device 5 sends a command to control the drain valve 22 to reduce the water yield, and opens the regulating valve 33 to begin to take water from the preparation reservoir 3 which stores the culture solution which is prepared in advance and is the same as the pool water in the culture pool 1 and inject the water into the culture pool 1;

s5: based on the water inlet pipe 31 which is arranged in an anticlockwise oblique downward opening manner, a vortex is formed in the culture pond 1 by the impulsive force of the inlet water and the bottom wall of the funnel-shaped culture pond 1 by taking the sewage discharge port 11 as the center;

s6: the residual baits, excreta, impurities, shrimp shells and dead shrimps sinking at the bottom of the pond are rolled by the large vortex at the moment and gathered to the sewage outlet 11 along the direction of the vortex to be slowly discharged;

s7: the high value live bait recovery device 2 of the sewage draining outlet 11 performs multiple filtration on the drained water, and separates and recycles the recoverable bait in the drained sewage;

s8: after the regulating valve 33 is opened to feed water in step S4, the water level sensor 32 monitors the water level, and when the water level reaches 35 cm, the control device 5 readjusts the water outlet amount of the blowoff valve 22 to increase;

s9: meanwhile, the control device 5 starts to count down after the regulating valve 33 of the water inlet pipe 31 is opened, and closes the drain valve 22 to prohibit water outlet after the timing is finished;

s10: after the blowoff valve 22 is closed, the water level sensor 32 monitors that the water level reaches 60 cm, the control device 5 gives a command to close the regulating valve 33, close the regulating valve 33 to complete water change, and loosen the pulling rope of the drain sealing cover 30 to close the drain 11.

The maximum water yield of the regulating valve 33 in the above steps can be adjusted to be larger than that of the blowoff valve 22, and when the drainage water is simultaneously opened, the water inflow is larger than that of the drainage water, so that the water level in the tank is prevented from being abutted to 20 centimeters.

The culture in the water changing process can be fished out of the culture pond to isolate and change water according to the condition, but can not be disturbed frequently.

The utility model utilizes the impact force formed by the water pressure of the inlet water to form a vortex to replace the vortex generated by external force in the prior art, the foreign matters to be discharged in the gathering water are gathered, the water inlet pipe is attached to the pool wall and is arranged obliquely downwards in the anticlockwise direction, the bottom of the breeding pool is in a cone shape, the drain is arranged at the lowest depression part, the utility model accords with the habit of the parent shrimps, and the parent shrimps can be actively kept away from the drain, and the utility model has the advantages of simple design, scientific and reasonable design, the vortex is continuously formed by the water pressure difference of the inlet water, the working strength of the operators is lightened, the damage brought to the parent shrimps by the water changing process is greatly avoided, the later mating and spawning effects of the parent shrimps are influenced by frequent frightening, the application is well realized in the actual breeding process, and all operations can be automatically completed only by the careful supervision of individual operators in the breeding process designed according to the scheme, for the frequent disturbance culture thing of changing of former a set of personnel individual pond, not only the waste time work efficiency is still low, and the damage to parent shrimp is big moreover, is unfavorable for the mating spawning work in later stage.

While the preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the appended claims be interpreted as including the preferred embodiment and all such alterations and modifications as fall within the scope of the invention.
