The principle of the invention for preventing the wading building from icing is as follows.
The iron frame 23 of the fish tank 2 is fixed to the wading structure 1 by an anchor bolt 24 and a bolt 25, and the length of the fish tank 2 can be determined according to the length of the wading structure 1. The freezing point of the salt water filled in the fish culturing tank body 2 and containing certain salinity is lower than that of the common fresh water, and when the common fresh water reaches the freezing point, the salt water in the fish culturing tank body 2 cannot be frozen. And in winter, the salt water can be heated by the heating mechanism, so that the salt water in the fish culture box body 2 is not easy to freeze and freeze. Therefore, the wading structure 1 has a certain heat preservation effect, the wading structure 1 is effectively prevented from being in direct contact with the ice layer 20, and the wading structure 1 is well protected.
The heating mechanism can be directly supplied with energy by the solar cell panel 4, the loss of energy is greatly reduced, the heating temperature of the heating mechanism can be controlled by the PLC 18, and the current passing into the heating mechanism can be controlled, so that the heating mechanism can heat the wading building 1 by the heat transfer principle and is favorable for the survival rate of the salted fish cultured in the fish culturing box body 2 except that the salted water in the fish culturing box body 2 is heated.
The concrete operation steps of the invention for preventing the wading building from icing are as follows.
Step one, installing a fish farming box body 2 through a fixing structure before the ice-forming period every year, wherein the water inlet depth of the fish farming box body 2 is 0.5-1.0 m, the water height is about 0.5m, the width is about 2m, and the length is determined by the anti-freezing range of a wading building.
Step two, arranging a fine sand layer 6 on the bottom layer in the fish culture box body 2, or arranging corallite above the fine sand layer 6, and planting water plants 7 above the fine sand layer 6, wherein the water plants 7 can be seaweed, seaweed and the like.
And step three, transversely arranging a plurality of heating pipes 5 above the fine sand layer 6. The solar cell panel 4 and the PLC 18 are arranged above the top end of the fish culture box body 2, and a temperature value and an oxygen content value are set in the PLC 18. And a light supplement lamp 3 is arranged on the inner wall of the top end of the fish culture box body 2. The high water level sensor 12, the dissolved oxygen sensor 15, the water temperature sensor 14 and the low water level sensor 13 are arranged on the inner wall of the fish culture box body 2 from top to bottom in sequence.
Step four, injecting saline water into the fish culture box body 2 through the water conveying mechanism. PLC controller 18 controls into water solenoid valve 101 and opens, and the simultaneous control water pump function holds the saltwater pump sending of pool to inlet channel 10 with the saltwater, carries out the water injection by inlet channel 10 to the inside of box 2 of breeding fish. The filling level should be higher than the low water level sensor 13 and lower than the high water level sensor 12. When the injected water is higher than the high water level sensor 12, the high water level sensor 12 sends a high water level instruction to the PLC controller 18, and the PLC controller 18 controls the water pump to stop operating and simultaneously controls the water inlet electromagnetic valve 101 to be closed.
And step five, putting the salted fish. The opening and closing door is opened, and the saltwater fish 8 is thrown from the throwing port 26. The species of the saltwater fish are flatfish, yellow croaker, grouper and other fishes living in a shallow sea water layer.
And step six, the oxygen delivery mechanism introduces oxygen into the saline water in the fish culture box body 2. When the dissolved oxygen sensor 15 detects that the oxygen content in the salt water is lower than a set value, the dissolved oxygen sensor 15 feeds a low-oxygen signal in the salt water back to the PLC 18, the PLC 18 controls the oxygen delivery pump to operate, and controls the supplementary feeding electromagnetic valve 91 to be opened, and oxygen is introduced into the fish culture box body 2 through the supplementary feeding pipe 9.
And step seven, the heating mechanism heats the saline water in the fish culture box body 2. In cold winter, when the outside temperature is lower than minus degree centigrade, and the water temperature sensor 14 detects that the water temperature is lower than the set value, the water temperature information is fed back to the PLC controller 18, and the PLC controller 18 controls the operation of the heating pipe 5 and controls the heating temperature of the heating pipe 5 to be between 15 degrees and 26 degrees.
Step eight, the light supplement lamp 3 illuminates the saltwater fish in the fish culture box body 2. When the external sunlight is insufficient, the PLC 18 controls the light supplement lamp 3 to operate, so that the lighting operation is realized.
And step nine, periodically discharging the saline water in the fish culture tank body 2. The PLC 18 controls the blow-down electromagnetic valve 111 to open, and the salt water in the fish culture box body 2 is discharged through the blow-down pipeline 11. When the water level is lower than the low water level sensor 13, the low water level sensor 13 sends a low water level signal to the PLC 18, and the PLC 18 controls the sewage discharge electromagnetic valve 111 to be closed, so that the excessive outflow of the salt water in the fish culture box body 2 is prevented. Meanwhile, the one-way valve 112 is set to only allow the salt water in the fish tank 2 to be discharged into the water body 19.
Step ten, regularly throwing baits. Bait is put into the fish box body 2 through the feeding port 26, and the fish feed amount is small in winter, so that the bait feeding is almost not needed, and the operation cost is reduced.
Step eleven, after the icing period is finished, salvaging the salt water fish in the fish culture box body 2, and dismantling the fish culture box body 2.
