By providing the bypass and the sea going check valve 118, when live fish is inputted into the negative pressure storage tank 110, the sea going check valve 118 can be opened if the density of live fish is low due to excessive water in the tank because the fish and water simultaneously enter the tank, and the water in the tank can be discharged into the sea under the action of the circulating water pump 171.

In addition, the filter 172, the circulating water pump 171 and the ultraviolet sterilizing device 173 of the vitamin sterilizing line 170 may be sequentially connected to the water outlet side of the on-off valve 117 at the bottom of the negative pressure tank 110. And a branch is also provided on the outlet side of the ultraviolet radiation sterilizing device 173 to the outside of the ship. A row of sea check valves 119 can be provided on the branch to provide on-off of the branch. By arranging the branch and the sea discharge one-way valve 119, the sewage in the tank can be discharged to the sea after being filtered and sterilized by ultraviolet rays in the cleaning mode, and the environmental pollution of the sea water is avoided.

With the above configuration, the feed replenishment and live fish transport system 100 of the embodiment of the present application can have several modes of operation:

1. feed replenishment mode: the air outlet valve 123 is opened, the vacuum fan 121 is started to discharge the air in the negative pressure storage tank 110 to the atmosphere, and a certain vacuum degree is formed in the negative pressure storage tank 110. The first three-way valve 111 is adjusted to be in communication with the feed replenishment line 130 so that feed on the quay can be sucked into the negative pressure storage tank 110 through the feed delivery hose for storage.

In addition, install rotatory export 1103 at negative pressure storage tank 110 top shell, rotatory export 1103 can evenly distribute the pellet feed in the jar, avoids causing the storage space extravagant because of the fodder angle of piling up.

The top end of the negative pressure storage tank 110 can be further provided with a level gauge, and the level height in the tank can be monitored in real time through the level gauge, so that the feed conveying time can be controlled.

When feeding or replenishing the aquaculture net, the second three-way valve 112 is switched to a state of communication with the feed feeding line 150. At this time, the fodder can enter the discharger 151 by gravity, simultaneously the air outlet valve 123 is closed and the air inlet valve 122 is opened, the vacuum fan 121 is started, and the fodder in the discharger 151 is continuously conveyed to each of the spouts 152 on the periphery side of the deck of the ship body by wind power conveyance, and is directly fed. Or after being switched by the three-way control valve 153, the feed in the feeder 151 is supplemented into the feed storage device of the cultivation net cage.

Wherein, the blanking device 151 and the vacuum fan 121 are set to be controlled by frequency conversion, and the blanking speed, the air supply amount and the air pressure can be adjusted according to the actual feed conveying amount and the conveying distance.

In addition, the vacuum line 120 may also be provided with a dust filter 124. According to the feed supplying and live fish transporting system 100, the feed adopts a negative pressure charging and positive pressure supplying mode, so that the safety risk caused by dust overflow is reduced to the greatest extent, the feed crushing rate is reduced to the greatest extent, and the operation cost is reduced.

2. Live fish transportation, vitamins, sterilization and epidemic prevention working modes:

first, before loading live fish, a certain amount of water is filled in the negative pressure tank 110, and then the first three-way valve 111 is switched to a state of communication with the live fish input line 140. Closing the air inlet valve 122 and opening the air outlet valve 123, and starting the vacuum fan 121 to generate negative pressure in the negative pressure storage tank 110, so that the live fish in the breeding fishing ground can be continuously pumped into the tank together with water. Meanwhile, the number of live fish entering the negative pressure tank 110 can be counted in real time using the fish counter 141. The fish and water may be separated by the first fish water separator 142 to control the amount of water entering the negative pressure storage tank 110, thereby controlling the fish packing density. When the density of the live fish in the tank is low, the circulating water pump 171 may be started while the sea chest check valve 118 is opened to properly discharge the water in the negative pressure storage tank 110.

When the fish is required to be unloaded outwards, the second three-way valve 112, the third three-way valve 113 and the first valve 162 are communicated, the air outlet valve 123 is closed, the air inlet valve 122 is opened, and the vacuum fan 121 is started to charge air into the negative pressure storage tank 110. The fish and water are introduced into the fish discharging main pipe 161 through the second and third three-way valves 112 and 113 by air pressure.

At this time, if classification is required, the first valve 162 may be switched to be in communication with the fish classifier 165, so that the live fish can be discharged after classification.

Alternatively, the first valve 162 may be switched to a state of being in communication with the second valve 163, and the second valve 163 may be switched to a state of being in communication with the outside, so that the live fish and water can be discharged to the outside together.

Alternatively, the second valve 163 may be switched to a state of being in communication with the second fish-water separator 166, and the second fish-water separator 166 may separate the fish from the water, and then the live fish may be transported to the live fish processing area on the wharf or the ship for preliminary processing by the third valve 164.

The feed replenishment and live fish transport system 100 of the present application avoids the installation of fish-catching devices in the negative pressure storage tank 110 by means of negative pressure loading and positive pressure unloading of fish. Thereby improving the space utilization and reducing the equipment maintenance and fault risks. And the fish-catching device is not required to be disassembled and assembled when the feed supply and live fish transportation modes are switched, so that the labor load is greatly reduced, and the operation and maintenance cost is reduced for users.

In addition, if it is inconvenient to pre-charge water in the negative pressure storage tank 110 in advance, the live fish input line 140 may be connected through the third three-way valve 113, and the fish in the farming facility may be gently sucked into the negative pressure storage tank 110 by the cooperation of the third three-way valve 113 and the second three-way valve 112.

The working procedures of vitamins, sterilization and epidemic prevention of live fish in the transportation process are as follows:

the on-off valve 117 is opened, the circulating water pump 171 is started, water in the negative pressure storage tank 110 enters the ultraviolet disinfection device 173 after being filtered by the filter 172, and finally returns to the negative pressure storage tank 110 through the oxygenation device 176 for adjusting the water temperature by the temperature control device 175.

If it is found that live fish is ill or the fish body carries germs, more than 98% of bacterial microorganisms in the water can be killed by the ultraviolet sterilizing device 173 provided in the vitamin sterilization line 170.

And the medicine adding device 174 arranged in the vitamin sterilization pipeline 170 can add symptomatic medicines to the sick fish in a targeted way to eliminate diseases and epidemic prevention. The function is especially suitable for sucking out the live fish from the net cage to the ship for medicated bath treatment when the live fish in the culture net cage are ill in large area. Thus, the medicine receiving density of the fish can be increased, the treatment effect is ensured, and the waste of the medicine and the pollution to the marine environment are reduced.

3. Dehumidification and cleaning mode of operation:

during the alternate transportation of the feed and live fish, the inside of the negative pressure storage tank 110 is cleaned and dehumidified to ensure the cleaning of the tank.

When dehumidification is performed, the intake valve 122 is opened, the vacuum fan 121 is started, and the fourth three-way valve 114 is switched to a state of communication with the heater 115. The air introduced into the negative pressure storage tank 110 is heated by the heater 115 to achieve the purpose of high-temperature dehumidification.

Also, during the feed transportation and replenishment process, the feed needs to be temporarily stored in the negative pressure storage tank 110 for a period of time. Because of high humidity at sea and large day and night temperature difference, condensed water is easy to generate on the inner wall of the negative pressure storage tank 110, so that the stored feed in the tank is easy to mould, and waste is caused. At this time, the hot air may be kept fed into the negative pressure tank 110 during the temporary storage of the feed so that the temperature in the negative pressure tank 110 is higher than the atmospheric dew point temperature. And the high-temperature air can reduce the air humidity in the tank and reduce the feed mildew risk.

During cleaning, the on-off valve 117 is opened, the circulating water pump 171 is started, and water in the negative pressure storage tank 110 is filtered by the filter 172, enters the ultraviolet disinfection device 173, and is discharged out of the ship through the sea discharge one-way valve 119. In the process, the sewage in the cleaning tank is discharged to the sea after being filtered and sterilized by ultraviolet, so that the environmental pollution is greatly avoided.

In addition, in the feed replenishment and live fish transport system 100, all external interfaces, such as the interface of the feed transfer hose with an external silo, are in the form of standard quick interfaces for easy quick insertion and quick connection during operation. Thereby effectively saving the operation time, reducing the operation difficulty and reducing the safety risk.

In addition, in the feed replenishment and live fish transport system 100, each valve is a remote control valve, so that centralized control can be performed at a remote control station, the operation risk is reduced, and the manpower load is reduced.
