Water circulation type fishing vessel

Abstract

The invention discloses a water circulation type fishing vessel which comprises a vessel, wherein the vessel is provided with a live well and a liquidometer which is used for detecting the water levelof the live well; a water inlet is formed in the bottom of the live well; a water inlet valve is arranged on the water inlet; the live well is further internally provided with a casing; one end of the casing is close to the opening of the live well; the other end of the casing is close to the bottom of the live well; a drainage device which can be moved up and down inside the casing is arranged inside the casing. The water circulation type fishing vessel is communicated with seawater or river water through the water inlet, the seawater or river wall can automatically flow into the live well under the action of pressure, and together with the drainage device, the seawater or river wall can be circulated in and out in the live well, then flowing water is made, and living fishes can survivewell; meanwhile, the drainage device can be moved up and down in the casing, the water drainage height of the drainage device can be adjusted according to fish capacities, water levels in the live well can be adjusted, in case of a small amount of fishes, the water level heights of the live well can be reduced, then the self weight of the vessel can be reduced, and the operation cost of a vessel owner can be reduced.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a water circulation fishing boat. Background technique [0002] With the improvement of people's living standards, great changes have taken place in the way of seafood supply, from the previous "frozen" supply system to the current "live and fresh" supply system. higher requirements. Therefore, in the transportation process, it is guaranteed that the live fish is not damaged, and it is guaranteed that the fish in the live fish compartment will be carried in time in a short period of time. The current live water transport ships use the method of pumping seawater into the fishing cabin, directly opening a hole at a fixed position on the side of the fishing cabin to overflow and discharge the living water circulation or directly opening a hole at the bottom of the fishing cabin to naturally flow into the seawater, and a fixed suction port is installed in the fishing cabin ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the running water in the running water tank can only maintain a water level no matter what the loading situation is. When the fish cargo is large, it is easy to damage the live fish. When the fish cargo is small, the unloading time is long, the energy consumption is large, and the operating cost is high.

The water level in the living water tank cannot be adjusted according to the amount of fishing cargo
